EXAMPLE 1

Manufacture of a Disposable Flat-Pack Liquid Container

[0171] A disposable flat-pack liquid container or bottle 2 is shown in FIGS. 1 to 7. The bottle 2 can have many different applications, such as those described in Example 5, including storing liquid for drinking, gardening purposes, catering and kitchen applications etc. However, the primary use of the bottle 2 is as a male urine storage container.

[0172] One of the advantages conferred by the bottle 2 is that it is stored in a flat, planar configuration 122, as shown in FIG. 1. In the flat configuration the bottle has a maximum length of about 330 mm and a width of about 200 mm, and the total height is less than 3 mm. The dimensions of the width and the length have been constrained by the sealing plate on the heat sealer used by the inventors. However, it will be appreciated that alternative heat sealers could be used which would allow the length and width to be varied.

[0173] The bottle 2 can then be readily converted to an open configuration 124, as shown in FIGS. 4 to 7, in which it holds liquid, such as water (or urine). In this configuration it will have a maximum height of about 135 mm, which is defined by the length of a tenth volume crease 106, which is described below. It will be appreciated that as the bottle 2 is converted from the flat configuration 122 into the open configuration 124, it must pass through a partially open configuration 123, which is shown in FIGS. 2 and 3.

[0174] Referring to FIG. 8, the bottle 2 is made from a single piece of polyethylene (PE) coated cardboard which is die-cut to form a planar cut-out 4. The laminated material is designed to withstand contact with liquid for extended periods of time, and retain its shape without going soggy and losing its shape or form, which would cause leaks. The cut-out 4 is pre-creased, having a central crease 6, which extends along the centre thereof dividing the cut-out 4 into a top face 8 (shown on the right hand side of FIG. 8) and a bottom face 10 (shown on the left hand side of FIG. 8). Extending diagonally across one end of the bottom face 10, the cut-out 4 also includes a flap crease 34, along which the cut-out 4 is folded to create a distal flap 36. Hence, while it will be appreciated that the cut-out 4 consists of one piece of card in the embodiment illustrated, the central crease 6 and flap crease 34 define three connected portions in the cut-out 4, namely the top face 8 (as shown in FIG. 9), the bottom face 10 (as shown in FIG. 10), and the flap 36 (as shown in FIG. 11). To better illustrate the various features of each of these portions they are illustrated separately in FIGS. 9 to 11. However, in practice, these portions are connected.

[0175] Turning now to the features defined by the shape of the cut-out 4 and the location of the creases. Referring again to FIG. 8, the central crease 6 separates the top face 8 from the bottom face 10. Extending spaced about 10 mm apart from, and parallel with the left and right peripheral edges 11, 13 of the top and bottom faces 8, 10, there are disposed left and right edge creases 14, 18, which create left and right flanges 16, 20, respectively. The cut-out 4 is folded over central crease 6 to produce the bottle 2 in its flat configuration 122, as shown in FIG. 1, such that the central crease 6 then defines a third side edge 12. Left and right flanges 16, 20 on the top and bottom faces 8, 10 are stuck together, due to a heat sealing step, such that the planar configuration of the bottle 2 is sealed along three edges, i.e. the third side edge 12, and the left and right flanges 16, 20.

[0176] The top face 8 is provided with a curved front edge 22. One section of the edge 22 is inwardly curved (i.e. concave), which leads into another curved section (i.e. convex) which forms a tab 26. The tab 26 comprises a rounded head 28 and a pinched neck section 30, along which extends a tab crease 24, which separates the tab head 28 from the rest of the top face 8 of the cut-out 4.

[0177] The bottom face 10 is also provided with a curved front edge 32, which is outwardly curved (i.e. convex). The front edge 32 is partially defined by the shape of the cut-out 4 and partially defined by the flap crease 34 which separates the bottom face 10 from the flap 36. A first rounded aperture 38 is disposed in a section of the bottom face 10 substantially adjacent to the front edge 32 and the left edge crease 14. To reduce the risk of tearing, the first aperture 38 is disposed a minimum of 10 mm from the first front edge 32. A second aperture 40 is disposed in the flap 36. The first and second apertures 38, 40, when aligned with each other, together define a shape which roughly corresponds to the shape of the head 28 of the tab 26, but is slightly larger to allow the head 28 to fit therethrough. Additionally, each aperture 38, 40 includes a straight edge 42 along one side thereof which defines an indent 44 which is slightly wider than the width of the neck 30 of the tab 26. The first and second apertures 38, 40 are shaped and disposed on the cut-out 4 such that they are mirror images of each other and the flap crease 34 defines the line of symmetry.

[0178] As can be seen in FIG. 8, the right edge crease 18 extends between the curved front edge 22 of the top face 8 and the curved front edge 32 of the bottom face 10. Similarly, the left edge crease 14 extends between an indentation 75, which is adjacent the curved front edge 22 of the top face 8, and the curved front edge 32 of the bottom face 10. The indentation 75 is defined in more detail below. As will be clear from FIG. 8, the top face 8, bottom face 10 and flap 36 are provided with further creases which divide these features into various sub-sections. To improve clarity, each of these elements is shown separately in FIGS. 9 to 11, although it will be appreciated in practice that the elements are not detachable from the cut-out 4.

[0179] Referring to FIG. 9, the top face 8 has three major sections, namely a top central section 46, a top left section 48 and a top right section 50. The top central section 46 is in the shape of a scalene triangle, the edges of which are defined by the third side edge 12, a first volume crease 52, which extends diagonally between the point where the left edge crease 14 and the third side edge 12 meet and a first top node 54, and a second volume crease 56, which extends diagonally between the point where the right edge is crease 18 and the third side edge 12 meet and the first top node 54. For reasons that will be explained below, the first top node 54 is disposed closer to the right edge crease 18 than the left edge crease 14. For instance, in the embodiment of the bottle 2 shown in the Figures, the first top node 54 is disposed 85 mm from the right edge crease 18 and 95 mm from the left edge crease 14.

[0180] The top left section 48 is in the shape of a right angle triangle, the edges of which are defined by the first volume crease 52, the left edge crease 14 and the third volume crease 58, which extends between the left peripheral edge 11 and the first top node 54, and makes a right angle with the left peripheral edge 11. The top right section 50 is an irregular four sided shape, the edges of which are defined by the second volume crease 56, the right edge crease 18, the concave portion of the curved front edge 22, and a fourth volume crease 60 which extends between the curved front edge 22 and the first top node 54.

[0181] The top face 8 also comprises six minor sections. One of the minor sections is the tab 26, which has already been described above, and the remaining five minor sections are a first isosceles triangle section 62, a second isosceles triangle section 64, a first fixing portion 66, a second fixing portion 68 and a third fixing portion 70.

[0182] The first isosceles triangle section 62, is in the shape of a right angled isosceles triangle, and is disposed adjacent to the top left section 48 and its longest edge is defined by the third volume crease 58. The remaining two edges are of equal length, one of which is defined by a fifth volume crease 72 which extends between the first top node 54 and a second top node 74. The remaining edge is defined in part by a portion of the indentation 75, which is defined by an L-shape in the cut-out 4, and in part by a triangle crease 76 which extends from the point where the left edge crease 14 and third volume crease 58 meet and towards the second top node 74. The second isosceles triangle section 64 is disposed adjacent to the first isosceles triangle section 62, and is roughly identical to it in size and shape, i.e. it also comprises a right-angled isosceles triangle. The longest edge of the second isosceles triangle section 64 is defined by the left edge crease 14. The remaining two edges are of equal length and defined by the indentation 75 and the triangle crease 76.

[0183] It will be appreciated that each of the first and second isosceles triangle sections 62, 64 can be viewed as defining a quartile of a square, and the relative positions of the first and second isosceles triangle sections 62, 64 means that together they define one half of the square.

[0184] The first fixing portion 66 is an irregular four sided shape and is disposed between the top right section 50, the first isosceles triangle section 62 and the tab 26. The sides of the first fixing portion 66 are defined by the fourth volume crease 60, the fifth volume crease 72, the curved front edge 22 in combination with the tab crease 24, and a first fixing crease 78, which extends from the curved front edge 22 to the second top node 74. The first fixing crease defines an angle of about 90 with the curved front edge 22.

[0185] The second fixing portion 68 is roughly in the shape of a right angled isosceles triangle and is disposed adjacent to the first fixing portion 66. The sides of roughly equal length of the second fixing portion are defined by the first fixing crease 78 and the curved front edge 22. The longest side is defined by a second fixing crease 80, which extends from the curved front edge 22 to the second top node 74.

[0186] The third fixing portion 70 is an irregular elongate shape, which is disposed adjacent to and extends away from second fixing portion 68. The third fixing portion 70 is separated from the second isosceles triangle section 64 due to the indentation 75 which defines a gap therebetween. The shape of the third fixing portion 70 is defined by the second fixing crease 80, the curved front edge 22, and the indentation 75.

[0187] It will be appreciated that the indentation 75 provides ample space to allow the second isosceles triangle section 64 to fold towards the first isosceles triangle section 62, and away from the third fixing portion without problem.

[0188] An aperture cut out in the shape of a first arrow 82 is provided adjacent the left edge crease 14, in the second isosceles triangle section 64. Similarly, an aperture cut out in the shape of a second arrow 84 is provided adjacent to the right edge crease 18 in the top right section 50. It will be appreciated that the first and second arrows 82, 84 need not be disposed adjacent the left and right edge creases 14, 18, respectively. Accordingly, in an alternative embodiment, the first and second arrows 82, 84 are disposed spaced apart from the left and right edge creases 14, 18, respectively, by about 5 mm (not illustrated).

[0189] Referring now to FIG. 10, the bottom face 10 comprises of three major sections, namely a bottom central section 86, a bottom left section 88 and a bottom right section 90. The bottom central section 86 corresponds to the top central section 46 in the top face 8. Hence, it is in the shape of a scalene triangle, the edges of which are defined by the third side edge 12, a sixth volume crease 92, which extends between the point where the left edge crease 14 and the third side edge 12 meet and a bottom node 94, and a seventh volume crease 96, which extends between the point where the right edge crease 18 and the third side edge 12 meet and the bottom node 94. As with the first top node 54, the bottom node 94 is disposed closer to the right edge crease 18 than the left edge crease 14.

[0190] The bottom left section 88 corresponds to the top left section 48. Accordingly, it is in the shape of a right angled triangle, the edges of which are defined by the sixth volume crease 92, the left edge crease 14 and an eighth volume crease 98, which extends at a right angle from the left edge crease 14 to the bottom node 94. The bottom right section 90 differs slightly in shape to the top right section 50. It is an irregular four sided shape, the edges of which are defined by the seventh volume crease 96, the right edge crease 18, the curved front edge 32 and a ninth volume crease 100 which extends from the curved front edge 32 to the first bottom node 94, and defines a right angle with the eighth volume crease 98.

[0191] The bottom face 10 also comprises two minor sections, namely a third isosceles triangle section 102 and a first handle section 104. The third isosceles triangle section 102 is disposed adjacent to the bottom left section 88, it is right-angled isosceles triangle, and roughly corresponds to the combined shape and size of the first isosceles triangle section 62 and the second isosceles triangle section 64. The sides of equal length of the third isosceles triangle section 102 are defined by the eighth volume crease 98 and the left edge crease 14. The longest side is defined by the tenth volume crease 106, which extends from where the left edge crease 14 meets the curved front edge 32 to the bottom node 94. As mentioned above, the tenth volume crease is about 35 mm long. The first handle portion 104 contains the first aperture 38, and is disposed between the third isosceles triangle section 102 and the bottom right section 90. The sides of the handle section are defined by the ninth volume crease 100, the tenth volume crease 106 and the curved front edge 32.

[0192] Referring to FIG. 11, the flap 36 consists of two portions, namely a second handle section 108, by which the bottle 2 can be carried when filled with liquid, and a further tapered section 110 extending therefrom. The second handle section 108 is defined by the shape of the cut-out, the flap crease 34, a further crease 112 which divides the tapered section 110 from the handle section 108. A further small elongated aperture 114 extends along the further crease 112, and provides ample space to allow the flap 36 to fold towards the tapered section 110 without problem. As can be seen in FIG. 8, the further crease 112 extends from the flap crease 34 from the point where the ninth volume crease 100 intersects the flap crease 34. The direction in which the further crease 112 extends is the mirror of the direction of the ninth volume crease 100 where the flap crease 34 is the line of symmetry. The further section 110 is adjacent to the second handle section 108 and its shape is defined by the shape of the cut-out, the flap crease 34, the further crease 112 and the further aperture 114.

[0193] In order to form the bottle 2, the cut-out 4 is folded along the central crease 6 so that the top face 8 overlies the bottom face 10, and the polyethylene coated surfaces 116 of the cut-out 4 face each other. It will be understood that the top central section 46 will directly overlie the bottom central section 86, and the top left section 48 will directly overly the bottom left section 88. The first isosceles triangle section 62 and the second isosceles triangle section 64 will also directly overlie the third isosceles triangle section 102. Additionally, the top right section 50 will overlie the bottom right section 90, but since the bottom right section 90 is larger than the top right section 50, it will extend beyond the top right section 50, as shown in FIG. 1.

[0194] The cut-out 4 is also folded along the flap crease 34 so that the flap 36 overlies the bottom face 10. It will be appreciated that the second handle section 108 will partially overlie the first handle section 104, and the second aperture 40 will directly overly the first aperture 38 to create handle 118. It will be appreciated that the handle 118 is reinforced due to the two layers which have been used to create it. The further section no will partially overlie the bottom right section 90.

[0195] The folded cut-out 4 is then heat-sealed along the left flanges 16, the right flanges 20, and around the flap 36, the second isosceles triangle section 64 and the third fixing portion 70 to produce the planar bottle 2. The heat-seal points 120 are shown as dashed lines in FIG. 1. Accordingly, the bottle 2 is flat when it comes off the production line, being the thickness of just two layers of polyethylene board. In the embodiment illustrated, the bottle has a flat area similar to an A4 envelope.

EXAMPLE 2

Converting the Bottle from the Flat Configuration to the Open Configuration

[0196] When the bottle 2 has been manufactured, according to example 1, it will be provided in a flat configuration 122, as shown in FIG. 1. This flat configuration 122 allows the bottle 2 to be stored and transported easily. However, it needs to be converted to an open configuration 124, as shown in FIGS. 4 to 7, before it can be used to receive a liquid.

[0197] When a person wants to convert the bottle 2 to the open configuration 124 they need to apply pressure at a point which is adjacent to the first arrow 82, and at a second point which is adjacent to the second arrow 84. Accordingly, the arrows 82, 84 indicate where and how the pressure should be applied. The pressure causes the first top node 54 to be displaced away from the bottom node 94, defining a volume 126 therebetween. The bottle 2 is shown in a partially open configuration 123 in FIGS. 2 and 3. As pressure continues to be applied, the first top node 54 will be forced further apart from the bottom node 94 until the second isosceles triangle 64 completely overlies the first isosceles triangle 62, preventing the bottle 2 from being opened any further. At this point the bottle 2 is in the open configuration 124.

[0198] As can be seen in FIG. 7, when the bottle 2 is in the open configuration 124 the bottom face 10 defines a V-shape, when viewed from the front. Additionally, the volume 126 can be accessed via an opening 128. The opening 128 is defined by a bottom lip 130, a side wall 132 and a top lip 134.

[0199] It will be appreciated that the bottom lip 130 is defined by the portion of the flap crease 34 which separates the bottom right section 90 from the further section 110. Similarly, the side wall 132 comprises the first handle portion 104 of the bottom face 10 overlaid with the second handle portion 108 of the flap 36. Accordingly, a front edge 136 of the side wall 132 is defined by the flap crease 34 which separates the first handle portion 104 from the second handle portion 108. The fact that both the bottom lip 130 and front edge 136 are defined by a folded crease is advantageous as it means the edges that will come into contact with a user's penis will have been softened by the fold. It will be appreciated that the top lip 134 is defined by the portion of the front edge 22 which defines an edge of the top right section 50.

[0200] Once the bottle 2 is in the open configuration 124, the tab 26 can be folded through the aperture 38 in the handle 118. As can be seen in FIG. 7, the handle 118 has been positioned to sit as high above the bottom lip 130 as possible. Due to the shape of the handle 118, the head 28 of the tab 26 is able to pass therethrough, and the neck 30 of the tab 26 can be placed in the indent 44. Accordingly, this creates a lock-and-key type arrangement effectively holding the tab 26 in place and locking the bottle 2 into the open configuration 124.

[0201] The bottle 2 made by the inventors and shown in the Figures has a volume 126 which can hold up to 1 litre of liquid when it is in the open configuration. However, it will be appreciated that the capacity of the volume 126 may be varied by varying the dimensions of the cut-out 4.

[0202] In use the V-shape of the bottom face 10 allows the bottle 2 to rest in the gap between a user's legs with the left flange 16 and right flange 20 resting on, or slightly above, the user's legs. As mentioned above, the first top node 54 and the bottom node 94 are both disposed closer to the right edge crease 18 than the left edge crease 14. This positioning causes the opening 128 to be provided in a relatively central position. This will mean it is more comfortable for a user to position their penis in the opening 128.

[0203] As can be seen in FIGS. 5 and 6, when the bottle 2 is in the open configuration 124 the bottom central section 86 defines a flat surface on which the bottle 2 can be placed. Accordingly, the bottle 2 can be left on a flat surface after it has been used and prior to it being disposed. After use, the bottle 2 can also be transported by a user by inserting a finger into the handle 118, or simply gripping the handle section 108, and carried with ease.

[0204] While not illustrated in the Figures, in another embodiment, the top central section 46 or the bottom central section 86 comprises a transparent window with a scale printed therein, or adjacent thereto. This would allow a person to pick up the bottle 2 by the handle 118, and holding the handle 118 loosely they could then use the scale to measure the amount of liquid contained in the bottle 2. The bottle must be in the fully open configuration 124 to give an accurate measurement of its content's volume.

EXAMPLE 3

Disposal Test

[0205] As mentioned above, a disposable male urine bottle 2 should be easy to dispose. Accordingly, the inventors tested samples of the polyethylene laminated cardboard used to make the bottle 2 to ensure the material fully macerated in the standard macerator machine, which is found in most hospital wards. The material was deemed to macerate adequately enough to flow away in standard sewerage systems.

[0206] A second phase test was then undertaken which involved testing if the complete bottle 2 made from the polyethylene laminated cardboard would also fully macerate. Again, the material was deemed to macerate adequately enough to flow away in standard sewerage systems.

EXAMPLE 4

Water Proof Integrity Test

[0207] Any male urine bottle which can be used by the NHS has to have 100% leak integrity for a minimum of 5 hours. The inventors filled a bottle 2, made according to example 1, in the open configuration, with approximately 600 ml of water. The inventors checked for leak evidence on an hourly basis. There was no evidence of leak failure after 24 hours, when the test was terminated.

EXAMPLE 5

Further Uses of the Container

[0208] While the above examples have been concerned with using the container 2 as a disposable male urine container 2, it will be appreciated that it could also be used for other applications, such as a disposable container for using to hold liquid for drinking; as a disposable container for using to hold liquid for gardening purposes; as a disposable container for using to hold engineering liquids; as a disposable container for using to hold liquid for catering and kitchen applications; and as a disposable container for using to hold liquid for other purposes in the healthcare sector.

EXAMPLE 6

An Alternative Disposable Flat-Pack Liquid Container

[0209] An alternative embodiment of the invention is shown in FIGS. 12 to 14. The bottle 200 shown in these Figures is similar to the bottle 2 shown in FIGS. 1 to 11 and described above.

[0210] However, the cut-out of bottle 200 does not comprise a distal flap 36. Instead, the cut-out defines a handle strengthening portion 202 in the top face 8. The handle strengthening portion 202 is disposed adjacent to the second isosceles triangle section 64 and defines the second aperture 40. The top face 8 is configured such that when the cut-out is folded along the central crease 6 to form the bottle 200, the second aperture 40 will lie directly above the first aperture 38, and define the handle 118.

[0211] Additionally, the cut-out 4 defines a flap portion 204 in the bottom face 10. The flap portion 204 is an elongate curved section disposed adjacent to the bottom right section 90. Additionally, the tenth volume crease 106 comprises a cut-out 208. The purpose for these are discussed below.

[0212] Finally, when the bottle 200 is manufactured, the folded cut-out is only heat-sealed along the left flanges 16 and the right flanges 20. No further heat-sealing is required, thereby simplifying the manufacturing process.

[0213] The bottle 200 may be converted to the open configuration 124 by applying opposing forces to the left and right flanges 16, 20, as explained above. While arrows 82, 84 are not shown in the Figures, it will be appreciated that while these are not essential but may be included in some embodiments if desired.

[0214] Similar to the bottle 2, once the bottle 200 is in the open configuration 124, the tab 26 can be folded through the aperture 38 in the handle 118. Due to the shape of the handle 118, the head 28 of the tab 26 is able to pass therethrough, and the neck 30 of the tab 26 can be placed in the indent 44. Furthermore, in this embodiment, the cut-out 208 is positioned to receive a distal end of the head 28 of the tab 26. Accordingly, the tab 26 is held in place at two points, thereby securely locking the bottle 200 into the open configuration 124.

[0215] The flap portion 204 can then be folded along crease 206 to define a bottom lip 130. It will be appreciated that the flap portion 204 can be folded prior to or after the bottle 200 has been converted to the open configuration 124. As explained previously, the folded crease is advantageous as it means the bottom lip 130, which will come into contact with a user's penis, is softened by the fold.

CONCLUSION

[0216] As illustrated in examples 3 and 4 the bottle was found totally satisfactory and fit for purpose as a male urine bottle for use in an NHS hospital. As explained in example 1, the bottle 2 is flat when it comes off the production line, being the thickness of just two layers of polyethylene board. It is then a simple process for a nurse (or possibly a patient) to apply pressure to the bottle 2, where indicated by arrows 82, 84, and lock it into the open configuration 124 ready for use. The bottle 2 designed by the inventors will hold up to 1 litre of liquid, thereby removing the need for a range of different capacity products.

[0217] Inevitably much less space will be required for transportation to and storage in hospital wards, and many more units can be stored, thereby reducing transport costs. In addition, the complete supply chain will have a greatly reduced carbon footprint due to fewer lorry journeys, and greatly reduced demand on warehousing space and operations. In addition the high efficiency in transportation makes it possible to manufacture the bottle 2 further from the point of use, giving more opportunity to take advantage of possible cheaper production centres.
