(22) In yet another aspect, the present disclosure provides a method of manufacturing a foldable box comprising providing a first sheet of material comprising a first layer and a second layer, wherein the first layer has a first surface and a second surface opposite to the first surface, the second surface has an adhesive coating, and the second layer covers the adhesive coating on the second surface; cutting a form of the first sheet of material; removing a part of the second layer to expose the adhesive coating of the first layer to obtain a second element; providing a second element comprising at least three pivotably connected parts; arranging for each of said at least three pivotably connected parts on the first element to be in contact with the exposed adhesive coating of the first layer; folding said at least three pivotably connected parts inwards along bevelled groove lines to form a box like structure wherein said pivotably connected parts form the sides of the box; removing the second layer from excess portion covering the adhesive surface of the first layer; folding the excess portion inwards and gluing the first layer to the outer sides of the at least three pivotably connected parts so that adhesive surface of the first layer is towards outer sides of the second element to cover the second element and form an outer surface of the foldable box, and attaching the first element to the second element so that the first element covers all outer surfaces of the second element.
(23) The present disclosure aims to provide a foldable box, a box folded from the foldable box and a method of manufacturing the foldable box. Notably, the foldable box of the present disclosure can be stacked in an unfolded position. Consequently, when needed, the foldable box can be folded into a box structure. Moreover, the foldable box and method of the present disclosure eliminates the need of extra space during transportation and warehousing of empty boxes. Additionally, the folded boxes are aesthetically appealing and durable. Furthermore, as the foldable boxes are stacked in a flat position, the structural integrity is not lost. Additionally, the boxes provide rigidity as tough material is used in the making. Herein, a foldable box refers to a box which is not folded i.e., is in a flat structure. The foldable box structure can be folded to produce the folded box.
(24) The system comprises a first element, and wherein, the second layer having an opening to partially expose the adhesive coating of the first layer. Herein, the first element is a cover element that forms the outer surface of the box. Notably, the first element is essentially a single sheet of material with minimal thickness that can cover the second element to provide structure and shape to the folded box. The first element comprises a stack of a first layer and a second layer, wherein the first layer has a first surface and a second surface opposite to the first surface, the second surface having an adhesive coating. Notably, the first surface of the first layer forms the outer surface of the foldable box, when folded and the second surface having the adhesive coating thereon enables the first element to adhere to the second element. The second layer is arranged to partially cover the second surface. In other words, the second layer partially covers the adhesive coating on the second surface and is arranged to keep the adhesive coating on the second surface of the first layer free from contact with air and other contaminants. Furthermore, the second layer prevents the adhesive coating of the first layer from drying. Moreover, the second layer has an opening that exposes the adhesive coating of the first layer. Herein, the opening in the second layer provides a space for the second element to come in contact with the first element. Moreover, once both the elements are in contact, the second layer of the first element can be removed (namely, peeled) in a methodical manner to expose the adhesive coating, thereby allowing different parts of the second element to be attached to the first element.
(25) Examples of the material used for manufacturing of the first layer, includes but is not limited to, paper and paper products, natural and synthetic fabrics, polymers.
(26) It will be appreciated that the first element is manufactured using materials which are highly flexibly and can be folded without any splitting, breaking, or fragmenting. Such material allows the first element, specifically the first layer of the first element, to be conveniently folded around the second element when folding the foldable box to obtain the folded box. Furthermore, the material for the second element is selected such that it can be easily peeled away from the adhesive coating without damaging the adhesive coating or leaving any residue thereupon, for example, a paper or plastic-based release liner.
(27) Optionally, the first surface of the first layer has printed information thereon. Herein, printed information refers to product printing, product information, logo, date of manufacture, date of expiry and the like. The printed information may also include patterns, for example graphic patterns, symbols and/or figures in different colours or shades of grey. Optionally, the printing is performed when the first element is in unfolded condition or when folded to a box structure or a combination of both.
(28) Moreover, information like product name, product logo and the like may be printed when the first element is in unfolded condition and further, information like date of manufacture, expiry, batch number and the like may be printed at a later stage when the foldable box is folded. Product printing is often required at a stage just before packing the product in the folded box. Furthermore, the information is printed using a printer or with the use of a hand-held stamp or both. Notably, the printed information is printed on all the sides of the box or on a pre-defined side. Herein, the printing varies based on a type of the product.
(29) Optionally, the first layer of the first element comprises scores that are covered by the second layer of the first element, wherein the first element is to be folded along the scores. Herein, scores refer to creases or perforation on the first layer of first element that allows easier folding thereof. Typically, scores are made using a piece of metal to compress the fibres of the first element in one small area in order to create a dip in the first element where it can easily fold. Additionally, scores enable the first element to be folded without buckling or cracking while being folded, and it decreases the chance that the folding process will hurt the printed information that is delicately placed on the first surface of first layer. Notably, the first layer of the first element has scores which are covered by the second layer. The scores ensure easy and proper folding of the first element after the second layer is removed. Moreover, the scores help in getting cleaner looking boxes and add-on to maintain the structural integrity of the folded boxes.
(30) The foldable box comprises the second element. Herein, the second element is manufacture using, but not limited to, cardboard, paperboard, plastic, polymer. Additionally, the material used in the manufacturing of the second element is comparatively rigid and strong than the first element. The second element comprises at least three pivotably connected parts, wherein at least one of the at least three pivotably connected parts is arranged to be in contact with the exposed part of the adhesive coating of the first layer. Notably, the at least three parts are pivotably connected to provide structure and rigidity to the foldable box. Typically, at least one of the three pivotably connected parts of the second element is arranged to be in contact with the adhesive coating of the first element. Moreover, the second element is placed on the first element in a manner that at least one of the at least three pivotably connected parts overlaps with the opening of the first element.
(31) Accordingly, in an exemplary embodiment, the second element comprise four pivotably connected parts (i.e., four sides of the foldable box), wherein each of the four pivotably connected parts is arranged to be in contact with the exposed part of the adhesive coating of the first layer. Notably, said four parts are pivotably connected to provide structure and rigidity to the foldable box. Each of the four pivotably connected parts of the second element is arranged to be in contact with the adhesive coating of the first element. Moreover, the second element is placed on the first element in a manner that each of the four pivotably connected parts overlaps with the opening of the first element.
(32) Herein, the first element is attached to the second element using the adhesive coating on the second surface of the first layer of first element. Furthermore, when the box is folded, the second element forms the rigid inner side and gives structure to the first element and shape to the box. Notably, the shape of the second element depends on the required shape of the box, when folded. Specifically, the number of pivotably connected parts depends on the required shape of the box. For example, four pivotably connected parts for a four-sided box, five pivotably connected parts for a five-sided box and so forth. The shape and size of the pivotable connected parts may vary depending on the shape and size of the box. For example, a four-sided box may have four pivotably connected parts of the same shape and the same size.
(33) It will be appreciated that for folding the foldable box, the second element is arranged on the opening in the second layer of the first element. Notably, prior to folding, the foldable box is substantially a two-dimensional structure, wherein the at least three pivotably connected parts are conjoined with each other using the first element (specifically, the first layer) to obtain a three-dimensional folded box.
(34) Optionally, the second element comprises bevelled groove lines along connecting edges of the at least three pivotably connected parts, wherein the bevelled groove lines enable fitting of the at least three pivotably connected parts when folded. Herein, the bevelled groove lines are obtained by chamfering the edges of at least three pivotably connected parts only along the edges that connect to each other during folding of the foldable box. The bevelled groove lines form a V-shaped structure that is not perpendicular to the faces of the piece between two pivotably connected parts that facilitates mating of a given connected part with another. Notably, at least three pivotably connected parts are required to form a closed structure. The number of pivotably connected parts and the degree of angle of the bevelled groove lines depends on the shape of the box.
(35) In an embodiment, the second element, when folded, forms sides of the foldable box and the foldable box further comprises a base element that is adhesively attachable to the sides of the foldable box and that forms a base thereof. Herein, the base element refers to an additional element that forms the base of the box when attached to the already formed sides of the box. Additionally, the base part is a separate element and is essential in order to complete the structure of the folded box. The base element is made of a similar material as the second element to provide rigidity. Notably, the base material is glued to the first element having an opening in the shape of the base, wherein, the shape of the base depends on the number of pivotably connected parts which further depends on the shape of the box. Furthermore, once the sides are formed by folding the pivotably connected parts, the base element is then placed in a way that the remaining adhesive surface of the base element gets adhesively attached to the inner sides of the box.
(36) In an exemplary embodiment, the first element comprises the first layer with the adhesive coating on second surface of the first layer, and the second layer. The second surface is covered with the second layer. Additionally, the second layer has an opening to expose the adhesive second surface of the first layer. Moreover, the second element comprises a first part, a second part, a third part and a fourth part. The first part is attached to the second part via the bevelled groove line. Similarly, the second part is connected to third part and the third part is connected to the fourth part. Since the second element has four parts, the foldable box can be folded into a folded box having a cuboidal shape, wherein the four parts form the sides of the cuboid. Furthermore, the groove line is processed preferably to have a 45-degree angle with a surface of the second element to enable folding of cuboidal box. Notably, the second element is placed to overlap the opening of the second layer of the first element. Moreover, the first part, the second part, the third part, and the fourth part of said pivotably connected parts are made to be in contact with the opening of the first element. Thus, all pivotably parts of the second element attach to the opening of the first element. Optionally, the adhesive surface of the first element is then folded inwards and is attached to sides of the second element. The second layer is removed completely to expose the adhesive coating of the first layer and the pivotably connected parts are folded. Thereafter, the four connected parts are along the bevelled groove lines in such a way that the fourth part of the second element mates with the first part of the second element. The box structure of the foldable box is closed/attached by connecting the adhesive coating of the first layer of the first element to the adjacent pivotably connected part of the second element that is completely covered with the first element. Said attachment is accomplished by the excess portion of the first element. Thus, after attachment, the outer surface of the adjacent side has two layers of the first element that cover the adjacent pivotally connected part and form a flat outer surface over it. Finally, a base part is separately constructed using a base shaped first element and a second element. Additionally, the base element is inserted from the top and is adhesively attached to the already formed sides of box. Such construction of the foldable box is illustrated further using
(37) In another embodiment, the second element further comprises a base part connected to the at least three pivotably connected parts, and wherein, when folded, the at least three pivotably connected parts form sides of the foldable box and the base part forms a base of the foldable box. Herein, the base part is an integral part of the second element which is further connected to the sides of the at least three pivotably connected parts. Notably, the base part forms the centre of the second element and the at least three pivotably connected parts are connected via the sides around it. The shape of the base depends on the number of pivotably connected parts which further depends on the shape of the box. Furthermore, when folded around the bevelled groove lines, the at least three pivotably connected parts forms the sides of the foldable box and the base part forms the base of the foldable box.
(38) In an exemplary embodiment, the first element comprises the first layer with the adhesive coating on the second surface of the first layer, and the second layer. Additionally, the second layer has an opening to expose the adhesive second surface of the first layer. Both layers, the first layer and the second layer, may be equal or different in size and shape, and may be arranged to be in contact with each other. Moreover, the second element comprises a first part, a second part, a third part, a fourth part and a base part. The base part is connected to the first part, second part, third part and the fourth part via bevelled groove lines. Furthermore, the second element is placed on top of the first element in such a way that the first part, the second part, the third part, the fourth part and the base part are in contact with the opening of the adhesive surface of the first layer of the first element. Notably, the first, second, third and fourth part can be pivotably turned in 90 degrees angle along the bevelled groove lines with respect to surface of the base part to form a cuboid box like structure. Additionally, part of second layer covering the adhesive surface can be removed and the first layer can be thus also glued to the other folded sides of the second element. In this embodiment, the attachment of the foldable box is accomplished by four excess portions of the first element. Each said excess portion has the shape and size of the adjacent pivotably connected part to cover outer side of said adjacent pivotably connected part throughout. Finally, a folded box with four sides and a base part is formed from the foldable box. Advantageously, the size and shape of the opening of the adhesive surface of the first layer of the first element and the size and shape of the second element correspond to each other so that the second element completely covers the exposed adhesive surface when attached. Such construction of the foldable box is illustrated further using
(39) The present disclosure further provides a box folded from the foldable box as described above. Herein, the resulting folded box is formed from the foldable box. Notably, the folded box comprises the first element and the second element wherein, the second element is connected to the first element using the adhesive coating on the first element.
