The description of one part applies by reference to another similar part, where appropriate, thereby reducing repetition of text without limiting the disclosure.
[0396]
[0397] The blank 1 is intended for folding to form a handheld tool and it has a flat, elongated, and essentially symmetric shape, its symmetrical axis A being indicated as a dash-dotted line in the figure.
[0398] The blank 1 comprises a top surface 2, a bottom surface 3 opposite to the top surface 2, a first side edge 4, a second side edge 4′ opposite to the first side edge 4, a front edge 5, and a rear edge 6.
[0399] The blank 1 essentially comprises three sections—a handle section 7, a functional section 8, as well as an intermediate section 9 which connects the handle section 7 with the functional section 8.
[0400] The blank 1 also comprises a bending aid in the form of downward bending lines 10, 10′ and an upward bending line 11 for facilitating bending or folding of the blank 1 in a predefined manner for forming the handheld tool with the desired form.
[0401] The upward bending line 11 which is shown as a dashed line has a shape of a smooth continuous line extending between two opposite edges 4, 4′ of the blank and comprising two essentially straight upward bending segments 12, 12′. Each one of the straight upward bending segments extends from a respective side edge 4, 4′ at the handle section 7 of the blank 1 over the intermediate section 9 towards the functional section 8 under an oblique angle with respect to the symmetrical axis A of the blank 1 such that the both upward bending segments 12, 12′ are connected over a middle or connecting segment 13 forming a blunt vertex at the functional segment 8 of the blank 1.
[0402] Depending on the specific embodiment, the shape of the vertex 13 may be different. In the embodiment of
[0403] The downward bending lines 10 comprise two symmetrically arranged smooth continuous lines which are shown as solid lines, each comprising a straight segment 14, 14′, extending from the rear edge 6 of the blank 1 towards the vertex 13, and a curved portion 15, each one of the curved portion 15 of the downward bending lines 10 ending at a respective junction point 16 at the upward bending line 11 in the vicinity of the vertex 13.
[0404] The straight segments 14, 14′ of the downward bending line 10 are extending longitudinally on both sides and close to the symmetrical axis A, such that a stripe extending from the rear edge 6 to the vertex 13 is formed.
[0405] In this embodiment, the straight portions 15 are parallel to each other and to the symmetrical axis A of the blank 1. Thus, the central stripe or middle channel has an essentially constant width over its whole length, except in the vertex region, in which the middle channel widens due to the curved portions 15 of the downward bending lines 10.
[0406] At the junction points 16, the upward bending line 11 lie essentially perpendicular to the downward bending line 10.
[0407] In some embodiments, the angle between the upward bending line 11 and the downward bending line 10 at the junction point 16 is between 60° and 90°, more specifically between 80° and 90°.
[0408] The upward bending segments 12, 12′ of the upward bending line 11 form or build an angle of approximately 26°.
[0409] The length of the tool is approximately 130 mm while its width is about 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 40 mm, 63 mm, and 27 mm, respectively.
[0410] Depending on the purpose and on the design of the tool, the angle between the upward bending segments 12, 12′ of the upward bending line 11 may vary, in particular, from approximately 20° up to approximately 66°.
[0411] The vertex 13 of the upward bending line 11 and the curved portions 15 of the downward bending line 10 show a circular curvature with approximately the same curvature radius as the vertex 13. The curvature radius in this embodiment is approximately 5 mm.
[0412] In the handle section 7 of the blank 1, elevated portions or bumps 17 of essentially round shape are provided.
[0413] At the ends of the straight segments 14, 14′ of the downward bending line 10, indentations 18 are provided in the rear edge 6 of the blank 1. The rear edge 6 is essentially straight and has rounded corners 19. The radius of curvature of the rounded corners is approximately 2 mm.
[0414] The side edges 4 of the blank 1 are straight and slightly inclined with respect to the symmetrical axis A of the blank in such a way that the width of the blank 1 at the rear edge 6 is smaller than the width of the functional section 8 of the blank 1.
[0415] In this embodiment, the front edge 5 has a circular shape with a curve diameter equal to the width of the functional section 8.
[0416] The depth of the indentations 18 in the rear edge are approximately 2 mm.
[0417] The length of the blank 1 is approximately 130 mm and the maximum width is 40 mm.
[0418] In the handle section 7 adjacent to the intermediate section 9 elongated transversal structures 20 are provided.
[0419] In this embodiment, the transversal structures 20 are provided in a shape of elongated bumps lying perpendicular to the symmetrical axis A of the blank 1.
[0420] The bending lines 10, 10′, 11 are formed as bending grooves scored in a surface of the blank.
[0421] In the case of the downward bending line 10, 10′, the bending groove is provided on the top surface 2 of the blank 1.
[0422] In the case of the upward bending line 11, the bending groove is provided on the bottom surface 3 of the blank 1.
[0423] Depending on the specific embodiment, the bumps and/or the bending aids may be provided with colour marks in order to facilitate the recognition of the handle section and/or the bending aids.
[0424] In the present embodiment, the blank 1 is a blank for a disposable spoon made from paper which is approved by the Food and Drug Administration (FDA). The area density of the paper is approximately 300 to approximately 400 g/m.sup.2.
[0425] As a basic material of the blank various materials may be used, such as paper, cardboard, metal, silicone, or any other suitable material.
[0426] In particular, the blank may comprise compostable and/or recyclable FDA-approved food-safe materials, including but not limited to paper, especially with an area density in the range from about 200 g/m.sup.2 to about 350 g/m.sup.2 and to paper an area density in the range from about 350 g/m.sup.2 to about 500 g/m.sup.2
[0427] The depth and the width of the bending scores depends in general on the material, thickness, and the purpose of the blank.
[0428] The blank 1 can be easily shaped into a handheld tool by manually bending it along the bending lines 10 and 11.
[0429] In particular, due to the bending scores provided on different surfaces of the blank 1 along the bending lines 10, 10′ and 11, it is particularly easy to bend the blank 1 downwards along the downward bending lines 10 and upwards along the upward bending line 11.
[0430] The bending lines 10, 10′ and 11 demarcate four separate areas of the blank 1, including two side wings 30 arranged symmetrically with respect to the symmetrical axis A of the blank 1, a middle lane 31 corresponding to the central channel along the symmetrical axis A, and a bow 32 which includes the functional section 8 and extends over the intermediate section 9 and partially circumvents the vertex 13. The side wings 30 extend from the rear edge 6 of the blank 1 over the handle section 7 and the intermediate section 9 to the vertex 13. At the side edges 4 of the blank, the side wings 30 and the bow meet at respective endpoints 21, 21′ which are endpoints of the upward bending line 11.
[0431] The downward bending lines 10 demarcate the border between the side wings 30 and the middle lane 31.
[0432] In order to shape the blank 1 into a handheld tool, the side wings 30 of the blank 1 are bent downwards (away from the viewer) with respect to the middle lane 31. The downward movement of the side wings 30 is indicated by downward movement arrow symbols 33.
[0433] At the same time, by bending or folding the side wings 30 downwards with respect to the middle lane 31, an elevated plateau along the middle lane 31 is formed, which lies between two brinks resulting from the folding of the blank 1 along the downward folding lines 10.
[0434] Due to the form-stability of the middle lane 31, in the beginning of the bending process, the longitudinal dimensions of the blank remain essentially the same and the endpoints 21, 21′ move essentially perpendicular to the symmetrical axis A of the blank 1 or to the middle lane 31. This means that along the circumference of the bow 32 a tensile stress or tension is building up, which extends along the front edge 5 and the side edge to the respective endpoint 21, 21′. The tensile stress along the circumference of the bow 32 is shown as bended arrows 40.
[0435] Simultaneously, with the bending of the side wings 30 downwards, the endpoints 21, 21′ at the side edges 4 are also moved or dragged down. This means that the endpoints 21, 21′ leave the plane of the drawing or the plane of the middle lane 31 and move down, travelling essentially in a plane perpendicular to the symmetrical axis A of the blank, resulting in a deformation of the bow 32.
[0436] In fact, due to the dragging down of the endpoints 21, 21′ by the wings 30, the bow 32 ceases to be a plane or essentially two-dimensional object and it becomes a three-dimensional object instead.
[0437] With the formation of side brinks along the upward bending line 11, the middle lane 31 provides a form-stable carrier construction of the tool. If the tool is provided as a spoon, in use, the middle lane 31 together with the side brinks acts to prevent cutting of mouth or lips of the user.
[0438] By continuing the downward bending of the wings 30, the tensile stress along the circumference of the bow 32 grows, pulling the tip 22 of the blank 1 towards the vertex 13 against the middle lane 31, resulting in an essentially axial compression force (indicated by a wide arrow 41) in the region of the vertex 13.
[0439] With the widening of the middle lane 31 at the vertex 13 and due to the tapered shape of the vertex 13, the compression force from the frontal part of the bow 32 is distributed over the width of the vertex 13 in such way that the compression stress at the perimeter of the vertex 13 is reduced.
[0440] With the reduction of the compression stress at the vertex 13 damage to the vertex 13 or vertex region can be avoided.
[0441] With the tensile stress and the central compression stress caused by the bending of the side wings 30, the planar geometry of the frontal part, in which the frontal part or the tip 22 remains in the plane of the middle lane 31, becomes energetically unstable.
[0442] By manually tilting the tip 22 of the functional section 8 upwards, the frontal part of the bow 32 can flip upwards and can take a stable position, in which the circumferential tension along the tension lines 40 is minimized. The upward movement of the front part of the bow 32 is shown by an upward movement arrow symbol 34.
[0443] After flipping upwards, the frontal part of the bow 32, and accordingly the functional section 8, takes a stable position.
[0444] In particular, by flipping upwards, the frontal part of the bow 32, the functional section 8 obtains a cup shape, the vertex 13 being the deepest point of the cup, and the blank 1 becomes a form-stable tool which in this embodiment is a small spoon.
[0445] As long as the side wings are kept bent down, especially by holding the tool in the hand, any deviation from this final shape would be energetically unfavourable, since it would increase the tensile stress along the circumvention of the bow 32.
[0446] Thus, by folding the side wings 30 downwards with respect to the middle lane 31, a form-stable handheld tool is formed. The bumps 17 and the transversal structures 20 can serve as grip structures or grippers for easier handling of the tool by the user.
[0447] The blank of
[0448] The bending lines may be scored or coined in the blank sheet of the blank material at predefined positions in correspondence with the specific embodiment of the blank.
[0449] The bumps 17 and the transversal structures 20 may be embossed or coined, by pressing the worksheet between two complementary tools of appropriate shape. In some embodiments, the bumps and/or the transversal structures are blind-embossed in the worksheet.
[0450] The blank 1 is cut out of the worksheet, in particular by means of die-cutting.
[0451] The formation of the bending lines 10, 11, bumps 17, transversal structures 20, and/or die cutting can be performed on a bigger area of a worksheet in such way that more than one blank out of a single panel is produced. Such a batch or bulk production can save time and costs in the manufacturing process.
[0452] A rolling machine, in particular a die-cutting roller, may be used for carrying out at least one of the previously mentioned operations.
[0453] In some embodiments, one or more reinforcement layers are provided, in particular of the middle lane 31.
[0454] The reinforcement may be formed as an additional material layer provided along the middle lane. The additional material layer may comprise metal, thermoplastic or thermoset material. It may be laminated, especially glued, onto the on the top surface 2 or on the bottom surface 3 of the blank 1. In some embodiments, reinforcement is embedded in the blank 1.
[0455] The reinforcement may comprise fibres embedded in the blank material or applied on one of the surfaces of the blank material.
[0456] In a special embodiment, the blank 1 of
[0457]
[0458] The blank 1a of
[0459] One difference to the embodiment of
[0460] Due to the arrangement of the downward bending lines 10, the middle lane 31 narrows towards the rear edge 6 turning essentially into a single line at the rear edge 6.
[0461] The vertex 13 has a flat tip and rounded corners. The junction points 16 between the downward bending lines 10 and the upward bending line 11 lie slightly apart from the rounded corners of the vertex on the straight segments 12 of the upward bending line 11. The angle between the straight segments 12 of the upward bending line 11 is approximately 22 degrees.
[0462] The blank 1a also comprises the transversal structure 20 and the bumps 17. The bumps 17 in this embodiment are elongated and transversally oriented.
[0463] The bumps 17 and the transversal structures 20 are coloured in order to designate the handle section for ease of use.
[0464] The particular shape of the blank 1a is attributable to the particular shape of the handheld tool which is to be formed out of the blank 1a. The tool formed out of the blank 1a of
[0465] The broad flat shape of the vertex allows for forming a cup that is shallow and broad. The broad flat shape may also be helpful to reduce the compression stress at the vertex and also to obtain the desired three-dimensional shape of the functional section of the tool.
[0466] The narrowing of the middle lane 31 towards the rear edge 6 may be useful for saving material during mass production of the tool. In particular, due to the tapered shape of the blank 1a, more blanks 1a can be accommodated side by side on the same area by placing them in alternating orientation, and hence more blanks can be produced out of a single workpiece.
[0467] The weakening of the plateau or central carrying construction by the narrowing of the main lane 31 at the rear edge does not significantly deteriorate the overall stability of the tool, since the main tensions are distributed over the intermediate section 9 and the functional section 8, with a maximum of compression stress in the region of the vertex 13.
[0468]
[0469] In contrast to the previous embodiments, the blank 1b of
[0470] The additional folding lines 10a and 10a′ act to provide a stronger middle lane 31.
[0471] The vertex 13 is slightly narrower as compared to the embodiment of
[0472] In the handle section 7 of the blank 1b, similar to the embodiment of
[0473] Different from the previous embodiments, the functional section 8 has a rounded, slightly elongated or elliptical shape, essentially defined for a specific purpose or intended use of the tool. In the present case, the tool to be formed is a spoon which, due to the sharper shape of the tip 22 and the additional downward folding lines 10 and 10′ is suitable for handling harder materials, for example hard ice cream or similar.
[0474]
[0475] The blank 1c of
[0476] Different to
[0477] The handle section 7 is narrow as compared to the widest part of the blank 1c. The widest part of the blank 1c is in the intermediate section 9, closer to the functional section 8.
[0478] The angle between the straight segments 12 of the upward bending line 11 is approximately 30.5 degrees.
[0479] The length of the tool is approximately 130 mm, the width at the widest part and at the rear edge 6 are approximately 40 mm and 35 mm respectively. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 40 mm, 60 mm, and 30 mm respectively.
[0480] The middle lane 31 has an additional reinforcement 50 shown as a black stripe in the area of the middle lane 31.
[0481] The reinforcement 50 is formed by embossing. In a general sense, the reinforcement 50 can also be formed by debossing.
[0482] A characteristic feature of the traditional Chinese spoon, besides its typical shape and proportions, is the shallowness of the spoon, or more precisely of the cup of the spoon. The shallowness of the cup has inter alia an advantage of allowing for rapid cooling of the content of the spoon whilst the spoon is in use.
[0483] Different from traditional Chinese spoons, the cup of the spoon made out the blank 1c of
[0484] The narrowness of the handle section results in a smaller tensile stress along the circumference of the bow 8 and accordingly in a smaller deformation of the bow from the initial plane geometry. Thus, a shallow form of the cup can be easily achieved.
[0485]
[0486] The angle between the straight segments 12 and 12′ of the upward bending line 11 is approximately 34.50 degrees.
[0487] The length of the tool is approximately 130 mm, the width at the widest part and at the rear edge 6 is approximately 50 mm and 35 mm, respectively. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 40 mm, 60 mm, and 30 mm, respectively.
[0488] The middle lane 31 has an additional reinforcement 50 in the form of a reinforcement layer provided along the symmetrical axis A of the blank 1d.
[0489] For a blank 1d that comprises paper, the reinforcement 50 can be provided using blind embossing, which can provide a strong middle lane 31.

[0507] As seen in
[0508] Due to this configuration of the middle lane 31 and the handle wings 60, a portion of the handle section between the handle wings 60 at the rear edge 6 can remain unfolded after the tool is formed. Thus, a comfortable handle with a kind of “volume-effect” can be shaped.
[0509] Further, the embodiment of
[0510] In other embodiments, the reinforcement may comprise surface layers laminated on the blank 1j, particularly at locations which are exposed to increased strain, like the middle lane 31, especially in the vicinity of the vertex 13 or the handle section, which is grasped by the user while using the tool.
[0511] The front edge 5 is straight such that the tip 22 of the front portion is essentially flat.
[0512] The length of the tool is approximately 160 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 50 mm, 80 mm, and 40, respectively.
[0513] The angle between the straight segments 12 of the upward bending line 11 is approximately 25.90 degrees.
[0514] The dimensions, especially the length of the intermediate section 9 and the functional section 8, as well as the angle between the straight segments 12 of the upward bending lines 11 may vary significantly depending on the purpose of the tool.
[0515] The length of the tool is approximately 160 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have respective lengths of approximately 50 mm, 80 mm, and 30 mm. The width of the middle lane 31 is approximately 4 mm.
[0516] The blank 1j also comprises grip structures or grippers. The grippers in this embodiment are provided in the form of elongated structures or stripes of protruded silicone.
[0517] In some embodiments, the grippers with coloured patterns are provided in the handle section 7. The colour pattern and the geometry of the grippers may vary, depending on the specific design of tool.

[0519]
[0520]
[0521] The front edge 5 has a circular shape such the tip 22 of the front portion or the function section 8 is essentially round.
[0522] The length of the tool is approximately 110 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 50 mm, 30 mm, and 30 mm, respectively. The width of the middle lane 31 is approximately 2 mm.
[0523] The angle between the straight segments 12 of the upward bending line 11 is approximately 66.00 degrees.
[0524] Due to its dimensions and shape, the blank 1k in the folded state results in a tool which is specifically suitable for using as a small scoop for ice-cream or rice, or as a ladle by bending the segment 8 in the other direction.
[0525] In some embodiments, the blank 1k comprises magnetized metal plates for ease of use.
[0526]
[0527] The embodiment of
[0528] The length of the tool is approximately 140 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 50 mm, 60 mm, and 30 mm, respectively. The width of the middle lane 31 is approximately 4 mm.
[0529] The angle between the straight segments 12 of the upward bending line 11 is approximately 34.10 degrees.
[0530] Such dimensions and shape of the blank 1l make the blank 1l suitable for forming a tool which can be used as a ladle, scoop, spatula, funnel, spade or shovel.
[0531]
[0532] This embodiment corresponds to the embodiment of
[0533] A tool formed out of such a blank 1m is particularly suitable for usage as a spatula, scraper, funnel, spade or shovel.
[0534]
[0535] The blank 1n of
[0536] The middle lane 31 with a reinforcement extends along the symmetrical axis A of the blank 1n over the intermediate section 9 and the handle section 7 without reaching the vertex 13 and the rear edge 6.
[0537] The length of the tool is approximately 140 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 50 mm, 50 mm, and 40 mm, respectively. The width of the middle lane 31 is approximately 2 mm.
[0538] The angle between the straight segments 12 of the upward bending line 11 is approximately 41 degrees.
[0539] The hole 70 at the vertex can serve for stress release and can facilitate the forming of the tool.
[0540] The particular shape and the holes 70 make the blank 1n particularly suitable for forming tools which can be used as a strainer, scoop or similar.
[0541] The plurality of holes 70 can be die-cut in the blank 1n. The holes are essentially round and have a diameter of approximately 1.5 mm.
[0542] The diameter of the holes can be varied, in particular in the range from 1 mm up to 3 mm, depending on the purpose of the tool.
[0543] In an embodiment, no holes in the functional section 8 and at the vertex 13 are provided. In the embodiment without holes, the middle lane and the reinforcement of the middle lane 31 can be extended to the vertex 13. Tools shaped out of such embodiments can be used for example as a spatula, scoop or ladle.

[0547] As can be seen from
[0548] Thus, the tapered shape of blanks, along with the design's technical importance discussed above, has an advantage from the manufacturing point of view. In particular, in the bulk production of the blanks worksheet material and production costs can be saved by alternating the orientation of adjacent blanks in the worksheet. Thus, due to the tapered shape of the blank, a saving of more than 10% in worksheet material in the bulk production can easily be achieved.
[0549] In this example, a material saving of 11.25% has been achieved.
[0550] Even in bulk production with smaller panels, i.e. in the case of smaller workpieces, the alternating orientation of the blanks can still lead to considerable savings.
[0551] In some embodiments of the manufacturing process, two blanks are produced and die-cut out of a single workpiece or worksheet. Due to the tapered shape of the blank, up to approximately 6% of material savings can be achieved, depending on the specific design of the blank.

[0559] In some embodiments, an extrusion-moulded rubber is used, as a reinforcement.
[0560] Further, in the embodiments of
[0561] It is also worth mentioning that the tools formed out of the blanks according the embodiments can be in general easily modified or transformed by changing the bending direction of the functional part of the blank. In particular, an energetically favourable stable configuration can also be achieved when the front portion of the functional section is bent in the same direction with respect to the plane of the middle lane as the side wings.

[0833] In use, the shape of the moulded blank 1p can change under pressure. In other words, the moulded blank 1p is flexible. Without external pressure or force, specifically external compressive forces, the blank 1p has a shape as shown in
[0834] The bending line 10p′ includes a groove or channel, wherein the groove is connected to two opposing parts. One part can bend or rotate around the groove, with respect to the other part.
[0835] A connection or joint between the first sheet portion 9-1p and the bending cum connection strip 11p acts as a bending line. The first sheet portion 9-1p can bend or rotate around the bending line, with respect to the bending cum connection strip 11p.
[0836] Similarly, a connection or joint between the second sheet portion 9-2p and the bending cum connection strip 11p also acts as a bending line. The second portion 9-2p can bend or rotate around the bending line, with respect to the bending cum connection strip 11p.
[0837] A method producing the blank 1p using pulp moulding is described below. The pulp moulding is also called heat pressing or thermoforming of fibre.
[0838] A fine wire mesh is initially provided. The wire mesh, which acts as a mould, is connected a chamber with a vacuum pump, wherein the wire mesh is suspended above a liquid return pool. The wire mesh has a shape of an upper or exposed surface of the blank 1p, wherein the surface includes bending lines. After this, a food-safe wet fibrous slurry is sprayed from below onto the wire mesh. The fibrous slurry is produced using food-safe fibers.
[0839] The vacuum pump then draws the slurry tightly against the wire mesh, wherein fibers of the slurry fills all or most gaps and spaces of the wire mesh while also drawing water of the slurry through the wire mesh into the vacuum chamber. When airflow through the wire mesh has been sufficiently blocked by the fibers, excess slurry falls into the return pool for recycling.
[0840] The wire mesh together with the fibers, which are shaped by the wire mesh, later moves to an area for drying the fibers, wherein the dried fibers form the blank 1p.
[0841] Following this, the wire mesh is separated from the dried blank 1p.
[0842] In one implementation, a blank produced by pulp moulding has a thickness of at least 1 millimeter (mm).
[0843] The pulp moulding can elevate a bowl section and a handle section of the blank whilst elevating or lowering bending lines of the blank according to design-engineered customized moulds used to produce the blank. These elevated parts and the lowered parts enable ease of use. In other words, these parts allow the blank to be folded easily. A user can simply pinch the blank to fold the blank to form a desired tool, such as a fork or spoon.
[0844] The blank produced by pulp moulding can also be branded or incorporated with a description through various methods, such as precision emboss and deboss.
[0845] This blank can remain essentially flat when packed due to flexibility and thinness of material used to produce the blank.
[0846] The pulp moulding allows production of thin walled products or blanks, which are often be well defined and have smooth surfaces.
[0847] In a further implementation, the blank is produced using thermoforming. While a mould forms a blank or product, the mould also produces heat to press and densifies the moulded product. The product is later ejected from the heated mould in its finished state as opposed to being dried in a heated oven. Such product often has the appearance of plastic material while the production process allows accurate formation of the product.
[0848] The blank is often designed, wherein the bending lines are placed on the same side of the blank. This allows the bending lines (and any crease and preforation) to be produced using the same mould. Furthermore, the placement of the bending lines is precise, since one, and not two moulds, is used to produce these bending lines.
[0849] In a generic sense, the blank can be made using various methodologies including moulding and/or injection moulding of different materials. Examples of this include FDA approved food grade (recyclable) silicone/rubber.
[0850] The blank can also be produced from different other materials, such as silicone, and it can have various thickness depending on material original strength and purpose of tool being produced by the blank.
[0851] In another embodiment, a sheet of paper is provided. After this, a mould is used to press the sheet to form the first sheet portion 9-1p together with the elevated second sheet portion 9-2p of the blank 1p. Following this, the bending line 10p and 10p′ are provided on the paper using scoring to form the finished blank 1p. Heat can also be applied to form the elevated second sheet portion 9-2p.
[0852] The blank 1p provides a benefit in that the separation of plane of the first sheet portion 9-1p from the plane of the second sheet portion 9-2p allows for easier folding of the blank 1p to form the spoon.
[0853] A user can just bend the bank 1p to form a spoon in one movement. The user presses the side edges 4 and 4′ toward each other. The bending cum connection strip 11p then allows and eases the first sheet portion 9-1p to bend or rotate around the bending line or joint, which is provided between the first sheet portion 9-1p and the bending cum connection strip 11p. Similarly, the bending cum connection strip 11p also allows and facilitates the second sheet portion 9-2p to bend or rotate around the bending line or joint, which is provided between the second portion 9-2p and the bending cum connection strip 11p.
[0854] In summary, the blank includes a first flat part, a second flat part, and a connection part. The first flat part is connected to the connection part, which is connected to the second flat part such that the first flat part is elevated with respect to the second flat part.
[0855] The elevation or separation between the two flat parts can be formed using different methods. Each method can include different process steps, such as application of pressure, application of vacuum or suction, and/or application of heat.
[0856] Referring to the blank, height of the elevation can be selected according to material of the blank. In general, the height should be more than a thickness of the blank.
[0857] The blank can be produced from paper material or metal material or other food-safe material.
[0858] In use, the elevated part is often selected to serve as a handle/bridge section.

Similarly, the bending line 10p′ comprises two straight bending line segment 14p1′ and 14p2′ and a curved bending line segment 15p′. The curved bending line segments 15p and 15′ are illustrated in
[0868] The straight bending line segments 14p1 and 14p2 and the straight bending line segments 14p1′ and 14p2′ extend longitudinally with respect to the blank 1q.
[0869] The blank 1q is formed by scoring the top surface 2 and the bottom surface 3 and by debossing the bottom surface 3.
[0870]
[0871]
[0872] The blank 1q provides a benefit in that the shape of the moulded blank 1q allows for easier folding of the blank 1q to form a spoon. A user can just bend the bank 1q to form a spoon in one movement by pressing the side edges 4 and 4′ toward each other.

[0877] In a general sense, dimensions of the blank 681 can also be adapted to form a ladle, a shovel, a spade, or other tools.
[0878] The thin blank 681 includes an elongated sheet 683 with a plurality of scored lines 685. The scored lines 685 are located on major surfaces of the sheet 683.
[0879] Each scored line 685 includes a narrow hollow channel, a bending groove, or a narrow elongated depressed area for facilitating bending or folding of the blank 681 to form the desired spoon. The depth and the width of the scored line are adapted according to material, to thickness, and to purpose of the blank 681.
[0880] In detail, the unfolded elongated sheet 683 is essentially flat and is symmetrical about its longitudinal axis.
[0881] The sheet 683 has a top surface with a bottom surface being provided opposite to the top surface. The sheet 683 also has a first side edge 683S1 with a second side edge 683S2 being provided opposite to the first side edge 683S1, and a front edge 683F with a rear edge 683R being provided opposite to the front edge 683F.
[0882] The front edge 683F and the rear edge 683R are placed at longitudinal ends of the sheet 683. The front edge 683F is connected to the first side edge 683S1, which is connected to the rear edge 683R. The rear edge 683R is connected to the second side edge 683S2, which is connected to the front edge 683F. Furthermore, the sheet 683 also comprises a bowl portion 702, a first handle portion 704, and a second handle portion 706, as illustrated in

A first end of the edge 702A is placed next to a first end of the edge 702B. A second end of the edge 702B is placed next to a first end of the edge 702C. A second end of the edge 702C is placed next to a first end of the edge 702D. A second end of the edge 702D is placed next to a second end of the edge 702A.
[0884] Similar to the bowl portion 702, the first handle portion 704 includes an essentially straight edge 704A with an essentially straight edge 704C, and an essentially straight edge 704B with an essentially straight edge 704D.
[0885] Similar to the bowl portion 702, the second handle portion 706 includes an essentially straight edge 706A with an essentially straight edge 706C, and an essentially straight edge 706B with an essentially straight edge 706D.
[0886] Referring to the bowl portion 702, the edge 702A is placed next to the front edge 683F or is a part of the front edge 683F. The edge 702D is placed next to the first side edge 683S1 or is a part of the first side edge 683S1. The edge 702B is placed next to the second side edge 683S2 or is a part of the second side edge 683S2. The edge 702C is placed to the edge 704A of the first handle portion 704.

[0890] Similarly, the edge 702B of the bowl portion 702, the edge 704B of the first handle bowl portion 704, and the edge 706B of the second handle portion 706 are placed such that they lie on a straight line.
[0891] Moreover, the sheet 683 also includes a pair of spoon rest grooves 735G1 and 735G2. The spoon rest grooves 735G1 and 735G2 can also be called fork rest grooves, in certain implementations. The spoon rest groove 735G1 is placed along the first side edge 683S1 and is placed between the first handle portion 704 and the second handle portion 706.
[0892] The other spoon rest groove 735G2 is placed along the second side edge 683S2 and is placed between the first handle portion 704 and the second handle portion 706.
[0893] The spoon rest grooves 735G1 and 735G2 curve inward or are curved tapered. In other words, they are not straight. This curve of the spoon rest grooves 735G1 and 735G2 is configured or designed such that they act to prevent tearing of the spoon rest grooves 735G1 and 735G2, especially when the blank 681 is folded to form the desired spoon. In short, the curve of the spoon rest grooves 735G1 and 735G2 serve to resistance tearing.

A first end of the bending line segment 710S is placed next to a first end of the first long-bending line segment 710L1. A second end of the first long-bending line segment 710L1 is placed next to a first end of the second long-bending line segment 710L2. A second end of the second long-bending line segment 710L2 is placed next to a second end of the short-bending line segment 710S.
[0898] The first long-bending line segment 710L1 is placed at a small angle to the second long-bending line segment 710L2. The short-bending line segment 710S is placed at a middle portion of the edge 702C of the bowl portion 702. The second end of the first long-bending line segment 710L1 and the first end of the second long-ending line segment 710L2 are placed at a midpoint of the edge 706C of the second handle portion 706.
[0899] Referring to the set of diagonal-scored lines, they include a first straight bending line segment 724 and a second straight bending line segment 726.
[0900] In detail, the first straight bending line segment 724 is placed on the bottom surface of the sheet 683 and it extends from one end of the short-bending line segment 710S to one end of the second-long edge 704C of the first handle portion 704, which is placed near to the first side edge 683S1.
[0901] The first straight bending line segment 724 of the diagonal-scored lines forms an angle of about 30 degrees with the first side edge 683S1.
[0902] Similarly, the second straight bending line segment 726 is placed on the bottom surface of the sheet 683 and it extends from another end of the short-bending line segment 710S to another end of the second-long edge 704C of the first handle portion 704, which is placed near to the second side edge 683S2.
[0903] The second straight bending line segment 726 of the diagonal-scored lines forms an angle of about 30 degrees with the second side edge 683S2.
[0904] Referring to the outer longitudinal-scored lines, they include a first longitudinal straight bending line 730L1 and a second longitudinal straight bending line 730L2. The first longitudinal straight bending line 730L1 is placed parallel to the second longitudinal straight bending line 730L2.
[0905] The first longitudinal straight bending line 730L1 extends from one end of the first straight bending line segment 724 to the edge 706C of the second handle portion 706. The one end of the first straight bending line segment 724 is placed near to the spoon rest groove 735G1.
[0906] Similarly, the second longitudinal straight bending line 730L2 extends from one end of the second straight bending line segment 726 to the edge 706C of the second handle portion 706. The one end of the second straight bending line segment 726 is placed near to the spoon rest groove 735G2.
[0907] In a special embodiment, the scored lines 685, such as the straight bending line segments 724 and 726, as well as the long-bending line segments 710L1 and 710L2 include sectional perforated lines to aid bending of the blank 681, especially when the blank 681 is thick or stiff. The sectional perforated line includes either through small slits, holes, or blind holes.
[0908] In one implementation, the think blank 681 has a paper material of more than 400 GSM.
[0909] Functionally, the blank 681 is intended for folding manually to form a spoon.
[0910] The bowl portion 702 is intended for folding to form a container of the spoon.
[0911] The first handle portion 704 and the second handle portion 706 are intended for folding to form a handle of the spoon.
[0912] The scored lines 685 allow parts of the blank 681 to bend toward different predetermined directions for forming the spoon.
[0913] In detail, the first straight bending line segment 724, the short bending line segment 710S, the second straight bending line segment 726 allow the respective parts of the blank 681 to bend to form the container of the spoon.
[0914] The first longitudinal straight bending line 730L1, the second longitudinal straight bending line 730L2, the first long-bending line segment 710L1, and the second long-bending line segment 710L2 allow the respective parts of the blank 681 to bend to form the handle of the spoon.
[0915] The first straight bending line segment 724, the short bending line segment 710S, and the second straight bending line segment 726 have curved parts, which are adapted such that these segments 724, 710S, and 726 form a smooth line which does not cut a user of the spoon. In other words, the smooth line does not have sharp corners, which can cut the user.
[0916] The first long-bending line segment 710L1 is placed at a small angle to the second long-bending line segment 710L2 for strengthening the handle. Put differently, this arrangement of the first long-bending line segment 710L1 and the second long-bending line segment 710L2 prevents the handle from bending.
[0917] The handle locking slits 740S1 and 740S2 are used for interlocking with each other such that the handle is formed in a firm or secured manner. In other words, the handle locking slits 740S1 and 740S2 act as a locking mechanism.
[0918] The spoon rest grooves 735G1 and 735G2 are intended for placing on a rim of a cup or bowl such that the spoon hangs on the cup or bowl. The spoon rest grooves 735G1 and 735G2 allow the rim to support the spoon.
[0919] In short, the blank includes a container portion, a handle portion, and two cut-off parts being positioned between the container portion and the handle portion.
[0920] The cut-off parts act as spoon rest grooves. The two cut-off parts also allow the blank to fold easily along a longitudinal axis of the blank. In other words, the cut-off parts enable the respective parts of the blank to bend easily about the first longitudinal straight bending line 730L1 and the second longitudinal straight bending line 730L2.
[0921] The handle portion includes a locking mechanism. The locking mechanism comprises the handle locking slits. The handle portion is intended for folding to form a handle of the hand-held tool while the locking mechanism serves to lock folded parts of the handle portion such that the folded parts are fixed to one another.

[1009] In use, a user inserts his finger into the finger handle portion to move the finger fork. The bowl portion is used for mixing or serving food. The bowl portion can be used for scooping and holding food or liquids.
[1010] These finger fork blanks are flat and are intended for folding to form finger forks. These finger fork blanks are variants of the fork blank of
[1011]
[1012] The finger fork blank 681-1F includes a front edge 683F with slots 763 for defining different prongs 766 of the fork. The finger fork blank 881-1F also includes a pair of fork rest grooves 735G1 and 735G2, a pair of handle locking slits 740S1 and 740S2 and a finger handle portion. In detail, the finger handle portion includes an inner hollow portion that is adapted for receiving a user finger.
[1013]
[1014]
[1015] The folding allows handle locking slits 740S1 and 740S2 of the blank 881-1F to interlock with each other. The handle locking slits 740S1 and 740S2 are curved such that the interlocking allows side edges 683S1 and 683S2 of the blank 881-1F to move and to tilt slightly with the respect to each to other.
[1016] In use, a user inserts his finger into a finger handle portion of the finger fork to move the finger fork, as shown in
[1017] The slight movement side edges 683S1 and 683S2 with respect to each other allows the handle portion to adapt and receive the finger. The handle portion can then wrap closely around the finger, thereby providing a snug or close fit.

[1029] The blank 981-1 includes spoon rest grooves 735G1 and 735G2 and handle locking slits 740S1 and 740S2. The blank 981-1 also includes straight bending lines 724 and 726, long-bending line segments 710L1 and 710L2, as well as longitudinal straight bending lines 730L1 and 730L2.
[1030] These bending lines 724 and 726, the line segments 710L1 and 710L2, and the straight bending lines 730L1 and 730L2 have perforations P. The perforation P refers to an opening or to a through hole.
[1031] The perforated bending line 724 allows easy bending of parts of the blank 981-1 which are attached to or are placed on the bending line 724. These parts are bent when the blank 981-1 is folded to form a spoon. Similarly, the perforated bending line 726, and the perforated bending lines 730L1 and 730L2 allow easy bending of the respective parts of the blank 981-1 to form the spoon.
[1032] The ease of bending is useful, especially when the blank 981-1 is thick, wherein the thickness makes the blank 981-1 stiff and difficult to bend.
[1033] Furthermore, the perforation allows for further cost saving. As an example, bottom-scoring, the perforation, and die-cut can be achieved in one process with one tool. Any top-scoring can be replaced by the perforated lines and by the bottom-scoring. This then enable saving of production cost as the only step is needed to provide the bending lines on the blank for forming spine and apex segment of the blank, which is resistant to tearing.
[1034] In short, the perforation of the blank 981-1, the scoring of the blank 981-1, and the die-cut to form the spoon blank with bending lines can be done using the same mould and at the same process step. This means the perforation can be done with minimal or no additional cost. This is useful for allowing the blank 981-1 to be produced a low cost.
[1035]
[1036] The spoon blank 981-2 includes spoon rest grooves 735G1′ and 735G2′, which have a narrow width. Furthermore, the blank 981-2 also includes a pair of long-bending line segments 710L1 and a pair of long-bending line segments 710L2. Both long-bending line segments 710L1 and both long-bending line segments 710L2 have perforations P.
[1037] The perforated long-bending line segments 710L1 and 710L2 allow easy bending of respective parts of the spoon blank 981-2 to form a spoon.
[1038]
[1039] The blank 981-3 includes spoon rest grooves 735G1′ and 735G2′, which have a narrow width. The blank 981-3 also includes straight bending lines 724 and 726, as well as a pair of long-bending line segments 710L1 and a pair of long-bending line segments 710L2.
[1040] In particular, a segment of the bending line 724 and a segment of the bending line 726 include perforations P. A long segment of the outer long-bending line segment 710L1 includes perforations P while a long segment of the outer long-bending line segment 710L2 includes perforations P.
[1041] The perforated bending lines 724 and 726 and the perforated long-bending line segment 710L1 and the perforated long-bending line segment 710L2 allows easy bending of the respective parts of the blank 981-3 to form a spoon.
[1042]
[1043] The blank 981-4 includes spoon rest grooves 735G1′ and 735G2′, which have a narrow width. The blank 981-3 also includes straight bending lines 724 and 726, as well as a pair of long-bending line segments 710L1 and a pair of long-bending line segments 710L2.
[1044] In particular, a segment of the bending line 724 and a segment of the bending line 726 include perforations P. A short segment of the outer long-bending line segment 710L1 includes perforations P while a short segment of the outer long-bending line segment 710L2 includes perforations P.
[1045] The perforated bending lines 724 and 726 and the perforated long-bending line segment 710L1 and the perforated long-bending line segment 710L2 allows easy bending of the respective parts of the blank 981-3 to form a spoon.
[1046] The length of the perforated segment can be adjusted according to material and to the thickness of the blank 981-3.
[1047] In summary, the blank has formation, strength and durability because it includes a few important lines, angles, curvatures and especially craniovertebral-vertebrae like structure. These features provide functions that are triggered in required proportions and are correlated with one another to produce the required dynamics in unity.
[1048] The blank has a bowl section, a neck section and a handle section, which are similar to the supportive structure of human beings, namely the vertebral column or the spine of which the significant parts include the atlas and axis combination, and together, they form a ‘craniovertebral vertebrae’ part of the blank.
[1049] When the blank is adapted for forming a spoon, the meeting of a blunted vertex at a base of the spoon with an ‘anterior arch of atlas’ part creates a semi-convex edge on a ‘craniovertebral vertebra’ part of a neck section of the spoon. In use, this acts to direct and distribute forces and pressure as well as to increase stability for forming a ‘spinous process’ (spine) part and an ‘articular pillars’ part of a handle section of the spoon through to a neck section of spoon.
[1050] A mere pinch on sides of a shoulder of the handle section effects or forms a bowl section of the spoon to rise in opposite direction on one surface, interchangeably to form a scoop section on the other surface.
[1051] The significant feature in the blank is the pair of curved portions (‘arch’ on the bowl section) at the end of the pair of bending lines of the handle section. The vertex of the upward bending line and the curved portions of downward bending line form a pair of circular curvatures (‘arch’) on the sides and a semi-convex edge on the neck section of the spoon.
[1052] In short, the atlas and axis combination of the blank acts as the ‘craniovertebral vertebrae’ that produces a powerful ‘semi-convex edge’ with an ‘anterior arch of atlas’ part at the vertex of the upward bending line at the central of base of the spoon.
[1053] The pair of circular curvatures and the ‘semi-convex edge’ on the neck section elevate to form a sturdy structure for the base of bowl section.
[1054] The ‘semi-convex edge’ of the pair of circular curvatures ensures balanced distribution of forces, strength and pressure on the base of bowl section as well as the neck section of the spoon. This ‘semi-convex edge’ of the atlas and axis is a critical attribute to the strong base of spoon and for the neck section and the handle section (akin to our skull and neck, the atlas and axis being pivotal in holding the skull as well as enabling flexibility of movement).
[1055] Equally significant, the end points (‘transverse process’) of these pair of curved portions (‘arch’) divert the immense pressure impact away from a head-on meeting point on vertex as compared to straight line endpoints. The diversion endpoints (‘transverse process’) of the curved portions (arch’) prevent tearing at meeting points on vertex that straight-line endpoints cannot withstand.
[1056] The curved portions (arch’) at the end of the pair of bending lines are in a pair. Without them, the ‘semi-convex edge’ cannot form, thus results to a weak spoon.
[1057] The blank's continuous directional bending lines with circular curvatures and ‘semi-convex edge’ are especially significant in preventing paper spoon from being easily ‘disfigured’ and/or deformed by users. Without precise directional lines, it is difficult to control formation of the paper spoon because apart from difficulty in bending thick stock, paper grains are never truly straight angle (180°) nor right angle (90°).
[1058] The ‘craniovertebral vertebrae’ part in the blank embodies a ‘spinous process’ part of handle section created with a pair of straight bending lines in the middle of the ‘articular pillars’, formed by two straight bending lines beside and parallel to the ‘spinous process’ straight lines.
[1059] Similar to human vertebral column, the blank's strength and durability are provided with one ‘spine’, reinforced by two ‘pillars/columns’ with four straight bending lines from the ‘semi-convex edge’ at the neck section of spoon to the edge of handle section of spoon to enable a strong and sturdy user-friendly handheld tool.
[1060] The other significant feature in the blank is the wide vertex where forces meet upon formation. Regarding the circular or round-cornered trapezoid vertex, the meeting of opposing force at this blunted ‘anterior arch of atlas’ wide vertex distributes energy/strength/pressure for and from the ‘semi-convex edge’ of the neck section and base of the bowl section.
[1061] The meticulously structured ‘anterior arch of atlas’ vertex transforms the central base of the bowl section together with the ‘semi-convex edge’ at the neck section of spoon into the strongest form to sturdily contain, carry and/or support volume/weighted content multiple times beyond its own weight (akin to human's ability to carry tremendous weight and/or variety of content on our head).
[1062] The blank serves as tools that are multiform and multifunction.
[1063] Referring to the bowl section of the blank, the bowl section is formed by a kind of anterior arch of atlas with wide blunted vertex, which can be circular or round-cornered trapezoid. The bowl section has enough depth, thereby allowing it to provide multi-functions to act as spoon, scoop, funnel or spreader. The depth also enables the bowl section to hold various contents, as what a spoon can do, including liquid or semi-liquid foods, and very small or powdery solid items.
[1064] Referring to the neck section of the blank, it has no hinge. It can serve as child proof eating utensils enabling spoonful of content to be consumed with ease. It is structurally sturdy and well supported from the handle section to the neck section and to the bowl section. It is user-friendly.
[1065] The neck section structurally prevents backflowing on its spoon side. The blank has circular curvature on its anterior arch of atlas vertex providing more than 2 distinct uses on each side of the tool. On one side, it can be a spoon or ladle holding liquids without possibility of leak/backward flow. On the other side, it can be a scoop or a funnel allowing liquids to flow through.
[1066] The neck section provides stability and ease of carrying multitude of content and volume multiple times its own weight. Upon elevation of parts of the blank, the ‘craniovertebral vertebrae’ part that is created by the pair of curved portions (‘arch’) equally distribute forces, equalizes burden and pressure thus form a stable neck section and base of spoon. This is a crucial point in its ability to carry with ease, content variations with volume multiple times heavier than itself.
[1067] Referring to the handle section of the blank, it is strong as the forces on the handle section are connected and directed from its ‘craniovertebral vertebrae’ part. A pair of downward bending lines forming the ‘spinous process’ part in the middle is further strengthened by ‘articular pillars’ formed by another pair of downward bending lines. In turn, they create a semi 3-tier slopes on the handle section upon formation.
[1068] The 3-tier slopes on top surface of the handle section create a formidable strong tri-spine to the handle section. This strong ‘tri-spine’ close-top handle section produces a practical, sturdy spoon that is comfortable to hold. The 3-tier slopes on spoon handle section provide users the ease of control. The sturdy handle section is further available in a variety of friction studs or grooves for greater grip to suit usage.
[1069] It should be noted that the term “scoring” can be replaced with the term “creasing” when producing the blank using paper.
[1070] The paper can have a weight of about 250 grams per square meter (gsm) to about 500 gsm.
