Description

[Technical Field]

[0001] The present invention relates to a used container recovery device and a method for using the used container recovery device. [Background technology]

[0002] Recycling of used beverage containers, food containers, and other items has been attracting attention as an approach to environmental issues. While metal and glass containers have traditionally been collected, washed, and reused, paper containers and other items have been collected and incinerated, with the heat generated during the process being used as energy, a process known as thermal recycling. However, there is an international trend toward the recognition that thermal recycling does not constitute recycling, as it merely utilizes the heat from incineration and does not actually recycle the materials. Therefore, efforts are being made to reuse paper containers after collection, such as by washing them. However, if containers such as paper cups are freely thrown into trash cans without controlling their direction, they become bulky, and even a small number of them can fill up the trash can, resulting in poor transportation efficiency.

[0003] In order to solve the above problems, Patent Document 1 discloses a device that collects used containers stacked in the same direction and stores them in a collection box in that state. Specifically, the device comprises a top surface with multiple openings for receiving paper cups, and a cylindrical body connected to the openings and guiding the paper cups vertically, so that used paper cups inserted through the openings and guided into the cylindrical body can be collected in a stacked state in the collection box. Note that the above document also states that the cylindrical body may be composed of multiple independent rod-shaped bodies. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-231003 Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned document discloses a device in which the side of the cylinder is folded like an accordion to reduce the contact area between the side of the paper cup and the inner wall of the cylinder, and a device in which the cylinder is composed of multiple independent rods, in order to prevent the paper cup from getting stuck in the middle of the cylinder. However, in these devices, the cylinder occupies a large proportion of the collection box, and the number of paper cups that can be collected relative to the volume of the collection box is reduced. In other words, the device described in the above document has room for improvement in terms of the so-called filling rate.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a collection device that can collect used containers that have been inserted in a stacked state and that can prevent a decrease in the filling rate of the collection box. [Means for solving the problem]

[0007] According to one aspect of the present invention, there is provided a used container collection device comprising an exterior body having a front panel, a back panel, and a pair of side panels, and a partition member having at least one horizontal partition panel arranged parallel to the front panel and at least one vertical partition panel arranged parallel to the side panels, wherein when the exterior body is placed over the outside of the peripheral wall of the collection box, the partition member divides the interior of the collection box into a plurality of spaces capable of accommodating stacked used containers. In this device, the front panel, the back panel, and the pair of side panels form the exterior body by interlocking their vertically oriented slits, the horizontal partition panel and the vertical partition panel form partition members by interlocking their vertically oriented slits, and the exterior body and the partition member are combined together by interlocking their vertically oriented slits. At both ends of the upper part of the horizontal partition plate, there are provided ears that protrude upward and to the side and have slits that engage with the slits in the side plate, and the width of the slits in the ears is the sum of the thickness of the side plate, the thickness of the peripheral wall of the collection box, and the thickness of the lid extending from the peripheral wall of the collection box, and the slits in the ears are fixed to the collection box by engaging with the lid and peripheral wall that are folded outward. [Effects of the Invention]

[0008] According to the above aspect, the partition member divides the interior of the collection box into multiple spaces that can accommodate used containers in a stacked state, so that the used containers can be collected in a stacked state. Furthermore, since the partition member is made of a plate-shaped member, the filling rate can be increased compared to the configuration in which a cylinder is provided for each area that accommodates used containers, as in the device described in the above document.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Device configuration]

[0011] Fig. 1 is a perspective view of a used container recovery device (hereinafter also referred to as "recovery device") 1 according to this embodiment, seen from diagonally above the front. Fig. 2 is a perspective view of the recovery device 1, seen from diagonally above the rear. Fig. 3 is a view (plan view) of the recovery device 1 seen from above.

[0012] In the following description, the containers are paper cups for drinks, but the recovery device 1 can also be applied to other containers, such as plastic cups and food containers.

[0013] The collection device 1 is used by placing it over the outside of a collection box for collecting paper cups, and by doing so, it has the function of dividing the inside of the collection box into multiple spaces that can accommodate multiple paper cups stacked on top of each other (hereinafter, this state will also be referred to as the stacking state).

[0014] The recovery device 1 comprises an exterior body 5 having a front panel portion 2, a back panel portion 3, and a pair of side panel portions 4, and a partition member 8 having at least one horizontal partition panel portion 6 arranged parallel to the front panel portion 2 and at least one vertical partition panel portion 7 arranged parallel to the side panel portions 4.

[0015] The numbers of horizontal partitions 6 and vertical partitions 7 are set appropriately taking into consideration the dimensions and filling rate of the collection box 11 and the paper cups 12 to be collected, which will be described later, and are preferably set so that the vertical and horizontal dimensions of one area defined by the horizontal partitions 6 and vertical partitions 7 in plan view are slightly larger than the diameter of the paper cup. In this embodiment, the interior of the exterior body 5 is divided into 25 areas, 5 rows and 5 columns. That is, there are four horizontal partitions 6 and four vertical partitions 7.

[0016] Fig. 4 is a view showing the front panel portion 2. Fig. 5 is a view showing the back panel portion 3. Fig. 6 is a view showing the side panel portion 4. Fig. 7 is a view showing the vertical partition panel portion 7. Fig. 8 is a view showing the horizontal partition panel portion 6. Fig. 9 is a view showing the pressing member 9.

[0017] The front panel 2, rear panel 3, side panel 4, horizontal partition panel 6 and vertical partition panel 7 are all made of paper with a thickness of about 0.5 to 2.0 mm. These are preferably waterproofed.

[0018] The front plate 2 is a substantially rectangular, flat member having a pair of vertical slits 20 extending upward from the lower end near the left and right ends. The vertical slits 20 are preferably provided with a claw portion 21 and a pair of horizontal slits 22 that engage with the front pressing member 9 described below.

[0019] The back panel 3 is a substantially rectangular, flat member having a pair of vertical slits 30 extending upward from the lower end near the left and right ends. The vertical slits 30 are preferably provided with a claw portion 31 and a pair of horizontal slits 32 that engage with the back pressure member 10 described below.

[0020] The side panel portion 4 is a substantially rectangular, flat member that has a pair of vertical slits 41 extending downward from the upper end near the front and rear ends, and four vertical slits 40 between the pair of vertical slits 41. In FIG. 6, the portion of the upper edge where the four vertical slits 40 are provided has an upwardly convex arc shape, but this is not a required configuration. It is also preferable that a receiving hole 43 be provided below the vertical slits 41 and a receiving hole 44 be provided below the vertical slits 40. It is also preferable that a horizontal slit 42 extend from the front to the rear and a horizontal slit 42 extend from the rear to the front.

[0021] The front plate 2 and the side plate 4 are combined by interlocking the vertical slit 20 of the front plate 2 with the vertical slit 41 of the side plate 4. The back plate 3 and the side plate 4 are combined by interlocking the vertical slit 30 of the back plate 3 with the vertical slit 41 of the side plate 4. These components are combined to form the exterior body 5. It is preferable that the upper corners of the front plate 2, the back plate 3, and the side plate 4 are chamfered as shown in Figures 4 to 6.

[0022] When the front plate 2 and the back plate 3 are orthogonal to the pair of side plate parts 4, the claws 21 and 31 engage with the receiving holes 43. By engaging the claws 21 and 31 with the receiving holes 43, the front plate 2, the back plate 3 and the pair of side plate parts 4 are positioned and fixed in an orthogonal state.

[0023] The vertical partition plate portion 7 is a substantially rectangular flat plate member, and is provided with four vertical slits 70 extending upward from the lower end.

[0024] The horizontal partition plate 6 is a substantially rectangular, flat member with four vertical slits 60 extending downward from its upper end. The horizontal partition plate 6 also has tabs 6A at both ends of its upper portion, each having a slit 61 that protrudes upward and laterally and engages with the slits 40 in the side panel 4. The width of the slit 61 in the tab 6A is the sum of the thickness of the side panel 4, the thickness of the peripheral wall 11B of the collection box 11, and the thickness of the lid 11A extending from the peripheral wall 11B of the collection box 12. Note that the "total" here does not only refer to the exact sum of the thicknesses, but also includes a slight deviation from the exact sum due to thickness tolerances and other factors. Considering that the collection box 11 may be used with a plastic bag or the like stored inside, as described below, the total may include the thickness of two plastic bags or the like. The slits 61 in the tabs 6A are preferably provided with tabs 6B.

[0025] The horizontal partition plate portion 6 and the vertical partition plate portion 7 constitute a partition member 8 by the vertical slits 60 of the horizontal partition plate portion 6 and the vertical slits 70 of the vertical partition plate portion 7 engaging with each other.

[0026] The partition member 8 is combined with the exterior body 5 by engaging the slits 61 of the ear portions 6A with the vertical slits 40 of the side panel portions 4. In the combined state, the claw portions 6B of the ear portions 6A engage with the receiving holes 44 of the side panel portions 4. This positions the exterior body 5 and the partition member 8.

[0027] When the collection device 1 is placed over the collection box 11 (described later), it is preferable that there be a gap between the lower end of the partition member 8 and the bottom of the collection box 11. Furthermore, it is preferable that the slit width of the vertical slit 70 within a predetermined range from the lower end be wider than the slit width above the predetermined range. If the slit width of the vertical slit 70 is constant throughout, when combined with the horizontal partition plate 6 (described later), the entire vertical slit 70 will come into contact with the horizontal partition plate 6. Therefore, if the vertical partition plate 7 is deformed during transport, the deformed state will be maintained by friction with the horizontal partition plate 6, and the used paper cups 12 may not fall to the bottom of the collection box 11. Furthermore, if the lower end of the partition member 8 comes into contact with the bottom of the collection box 11 due to dimensional variations, the partition member 8 may be deformed, and the used paper cups 12 may not fall to the bottom of the collection box 11. In this respect, in the configuration of this embodiment, the wider slit width does not come into contact with the horizontal partition plate portion 6, so even if the paper cups 12 are deformed, they will return to their original shape due to the weight of the paper cups 12, and the paper cups 12 will reach the bottom of the collection box 11. In addition, there is a gap between the lower end of the partition member 8 and the bottom of the collection box 11, which can suppress deformation due to the above-mentioned dimensional variations.

[0028] Furthermore, it is preferable that the portion of the vertical slit 70 above the predetermined range be a wavy curve. This is because the wavy shape increases the contact pressure with the horizontal partition plate 6, making it possible to suppress misalignment between the vertical partition plate 7 and the horizontal partition plate 6.

[0029] 1 and 2, in this embodiment, the vertical dimension of the back panel 3 is larger than the vertical dimensions of the front panel 2 and the side panel 4, but this is not limited to this, and for example, the vertical dimensions of the back panel 3 and the front panel 2 may be the same. In this embodiment, the vertical dimension of the back panel 3 is larger than that of the other members in order to display on the part that protrudes upward from the other members that the device is a collection box for used paper cups, how to put used paper cups in, etc.

[0030] The outer casing 5 and the partition member 8 are combined, and the front plate portion 2 and the back plate portion 3 are fixed in this state so that they are perpendicular to the pair of side plate portions 4, by attaching the front pressing member 9 and the back pressing member 10.

[0031] 9 is a diagram showing the front pressing member 9. The front pressing member 9 and the rear pressing member 10 are identical components, and are distinguished as the front pressing member 9 and the rear pressing member 10 depending on where they are placed. In the following description, when there is no need to distinguish between them, they will simply be referred to as "pressure members 9, 10."

[0032] The front pressing member 9 is an L-shaped, flat member with a first pressing portion 9A on one side that contacts the front panel 2 and a second pressing portion 9B on the other side that contacts the side panel 4. The interior angle between the first pressing portion 9A and the second pressing portion 9B is approximately 90 degrees. The front pressing member 9 also has a slit 91 that extends on the same line as the first pressing portion 9A and a slit 92 that extends on the same line as the second pressing portion 9B. It is preferable that both slits 91 and 92 are wavy, as this makes them less likely to come loose after being assembled to the exterior body 5.

[0033] The front pressing member 9 is attached to the exterior body 5 so that the slits 91 and 92 are engaged with the horizontal slits 22 and 42, respectively. In other words, the front pressing member 9 is disposed at the location where the front plate 2 and the pair of side plate portions 4 intersect. This fixes the front plate 2 and the side plate portions 4 in a perpendicular state.

[0034] As described above, rear pressure member 10 is the same component as front panel member 9, and includes third pressure portion 10A that contacts rear panel 3, fourth pressure portion 10B that contacts side panel 4, slit 101 that extends on the same line as third pressure portion 10A, and slit 102 that extends on the same line as fourth pressure portion 10B. Rear pressure member 10 is attached to exterior body 5 so that slits 101 and 102 mate with horizontal slits 32 and 42. In other words, rear pressure member 10 is disposed at the location where rear panel 3 and the pair of side panels 4 intersect. This secures rear panel 3 and the side panels 4 so that they are perpendicular to each other.

[0035] [How to use the device]

[0036] Next, a method of using the recovery device 1 configured as above will be described with reference to Figures 10 to 12. Figure 10 is a diagram showing a schematic diagram of the process of using the recovery device 1.

[0037] As described above, the collection device 1 is used to collect used paper cups 12. One possible place where it might be used is a food court in a shopping mall, event venue, or the like. In such places, water is often provided from a water dispenser, and paper cups are used. A collection box 11 for collecting used paper cups is installed near the water dispenser or near a place where used dishes, trays, and the like are returned. However, if used paper cups are placed into the collection box 11 without controlling their direction, they become bulky and the collection box 11 will become full with even a small number of cups. In this regard, the collection device 1 according to this embodiment allows used paper cups to be collected in a stacked state. A method for using the collection device 1 will be described in more detail below.

[0038] The recovery device 1 is assembled by assembling the front panel 2, the pair of side panel parts 4, and the partition member 8, and is then folded flat along each of the engagement parts (see (A) of Figure 10) before being transported to the location of use together with the back panel 3 and the retaining members 9, 10. This takes up less space and makes it easier to carry than if it were unfolded into a box shape before transporting. At this stage, the front panel 2, the pair of side panel parts 4, and the partition member 8 are not pushed in until the ends of each slit abut against each other. This is to make it easier to fold. Also, once each claw part engages with each receiving hole, it becomes impossible to fold.

[0039] The back panel 3 may also be folded in an assembled state.

[0040] When the device arrives at the place of use, the front panel 2 and the pair of side panel parts 4 are unfolded so that they intersect at right angles, and the back panel part 3 is assembled.

[0041] Although a dedicated collection box may be used as the collection box 11, in this embodiment, a cardboard box that has contained unused paper cups, i.e., a cardboard box that has been used to deliver paper cups, is used. The unused paper cups are removed from the collection box 11, and the lid 11A of the empty collection box 11 is folded back outward.

[0042] Then, the collection device 1 is placed over the collection box 11 from above so that the peripheral wall 11B and the folded-over lid portion 11A of the collection box 11 fit into the slits 61 of the ear portions 6A (see FIG. 10(B)). At this time, each member is pressed down until the slit ends of each engaging portion abut against each other (that is, until each claw portion engages with each receiving hole). Then, once each claw portion engages with each receiving hole, the pressing members 9 and 10 are assembled.

[0043] 11 and 12 are cross-sectional views of the state in which the collection device 1 is placed over the collection box 11 (hereinafter also referred to as the set state). Fig. 11 is a cross-sectional view taken along line XI-XI shown in Fig. 3, and Fig. 12 is a cross-sectional view taken along line XII-XII shown in Fig. 3.

[0044] In the set state, the peripheral wall 11B of the recovery box 11 is surrounded by the front panel 2, the back panel 3, and a pair of side panel parts 4, and the interior of the recovery box 11 is divided by the peripheral wall 11B and the partition member 8.

[0045] In the set state, the reaction forces of the four folded lid portions 11A act on the exterior body 5 and the horizontal partition plate portion 6. This makes it even more difficult for the collection device 1 to be folded.

[0046] Considering that the paper cups 12 may contain leftover water or the like, it is preferable that the collection box 11 be made of waterproof cardboard. However, even waterproof cardboard is vulnerable to water penetration from the outer cross section. Therefore, a plastic bag or the like may be placed in the collection box 11 with its opening open, and then the collection device 1 may be placed over it. In this case, a predetermined area from the top of the plastic bag or the like is folded back in the same way as the lid 11A of the collection box 11.

[0047] Once the container is set up as described above, it is placed at the place of use (see (C) of Figure 10). When a used paper cup 12 is dropped into one of the divided areas of the collection box 11, it falls along the partition members 8 etc. in the same position as when it was dropped in, and is stacked within that area.

[0048] When the collection box 11 is filled with used paper cups 12, the collection device 1 is pulled upward from the collection box 11 (see (D) of FIG. 10). After the collection device 1 is pulled out, the collection box 11 contains stacked used paper cups 12 in a 5-row x 5-column arrangement. In other words, the collection box 11 can be transported by closing the lid 11A.

[0049] [Summary of effects]

[0050] The configuration and effects of the recovery device 1 according to this embodiment described above will be summarized.

[0051] (1) According to this embodiment, a used container recovery device 11 is provided, which includes an exterior body 5 having a front panel 2, a back panel 3, and a pair of side panel parts 4, and a partition member 8 having at least one horizontal partition panel part 6 arranged parallel to the front panel part 2 and at least one vertical partition panel part 7 arranged parallel to the side panel part 4, and when the exterior body 5 is placed over the outside of the peripheral wall 11B of the recovery box 11, the partition member 8 divides the interior of the recovery box 11 into multiple spaces that can accommodate used paper cups (containers) 12 in a stacked state. With this device, used paper cups 12 are stored in each of the multiple spaces within the recovery box 11 in a stacked state, which allows for a higher filling rate than when used paper cups are freely inserted without any restriction on direction.

[0052] In this device, the front panel 2, the back panel 3, and the pair of side panel 4 configure the exterior body 5 by interlocking their vertically oriented slits 20, 30, 41, and the horizontal partition panel 6 and the vertical partition panel 7 configure the partition member 8 by interlocking their vertically oriented slits 60, 70, and the exterior body 5 and the partition member 8 are combined by interlocking their vertically oriented slits 40, 61. In this way, the slits for combining the various components are all vertical slits, so that the device can be folded flat along the interlocking portions as needed.

[0053] (2) In this embodiment, ears 6A are provided at both ends of the upper portion of the horizontal partition plate 6, protruding upward and to the side and having slits 61 that engage with the slits 40 of the side plate 4. The width of the slits 61 of the ears 6A is the sum of the thickness of the side plate 4, the thickness of the peripheral wall 11B of the collection box 11, and the thickness of the lid 11A extending from the peripheral wall 11B of the collection box 11. The slits 61 of the ears 6A are fixed to the collection box 11 by engaging with the lid 11A and the peripheral wall 11B folded outward. This makes it possible to suppress deformation of the collection device 1 by utilizing the reaction force of the lid 11A.

[0054] (3) In this embodiment, the collection box 11 is a box in which unused paper cups 12 are packed. This allows the delivery box of the paper cups 12 to be used as a collection box as is. Furthermore, when the collection box 11 is full of used paper cups 12, it becomes ready for transport simply by removing the collection device 1 and closing the lid 11A. Note that the delivery box may have information on it that is inconsistent with the atmosphere of the place of use, such as product information such as the product number and number of cups contained, or information on the delivery destination. However, with the collection device 1 according to this embodiment, the lid 11A is folded back, and the exterior body 5 hides the peripheral wall of the collection box 11 and the folded back lid 11B, so these information do not spoil the appearance of the place of use.

[0055] (4) In the recovery device 1 according to this embodiment, at least a portion 70A of the vertical slit 70 of the vertical partition plate portion 7 is a wavy curve. This allows for stronger engagement with the horizontal partition plate 6, preventing the two from becoming separated during transport, etc. Note that it is sufficient for the slit to be wavy in at least one of the vertical partition plate portion 7 or the horizontal partition plate portion 6.

[0056] (5) The collection device 1 according to this embodiment includes at least one front pressing member 9 having a first pressing portion 9A in contact with the front panel 2 and a second pressing portion 9B in contact with the side panel 4, and at least one back pressing member 10 having a third pressing portion 10A in contact with the back panel 3 and a fourth pressing portion 10B in contact with the side panel 4. When the front panel 2 and the pair of side panel 4, and the back panel 2 and the pair of side panel 4, are perpendicular to each other, the front pressing member 9 is disposed at the location where the front panel 2 and the pair of side panel 4 intersect, and the back pressing member 10 is disposed at the location where the back panel 3 and the pair of side panel 4 intersect. This more reliably maintains the rectangular shape of the exterior body 5 in a plan view.

[0057] (6) In the recovery device 1 according to this embodiment, the vertical slits 70 of the vertical partition unit 7 are arranged upward from the bottom end, and the vertical slits 60 of the horizontal partition unit 6 are arranged downward from the top end, and the slit width of a predetermined range (70B in FIG. 7) from the bottom end of the vertical slit 70 of the vertical partition unit 7 is wider than the slit width of the portion above the predetermined range. As a result, the predetermined range from the bottom end of the vertical partition unit 7 does not come into contact with the horizontal partition unit 6. In other words, it is possible to prevent the vertical partition unit 7 from getting caught on the horizontal partition unit 6 and deforming, which can cause the paper cups 12 to become stuck midway.

[0058] (7) When the collection device 1 according to this embodiment is placed over the collection box 11, there is a gap between the lower end of the partition member 8 and the bottom surface of the collection box 11. This prevents the lower end of the partition member 8 from coming into contact with the bottom surface of the collection box 11, causing deformation and causing the paper cups 12 to become clogged.

[0059] (8) The recovery device 1 according to this embodiment is assembled from the front panel 2, the side panel 4, and the partition member 8, and is transported to the place of use in a flattened state along each of the mating portions. Therefore, it is not bulky when transported to the place of use.

[0060] When in use, the front panel 2 and the pair of side panel parts 4 are unfolded so that they intersect at right angles, the back panel part 3 is assembled, unused containers are removed, the lid part 11A of the empty collection box 11 is folded outward, and the collection device 1 is placed over the collection box 11 from above so that the peripheral wall 11B of the collection box 11 fits into the slit 61 of the ear part 6A. This makes it possible to easily set the collection device 1 on the collection box 11.

[0061] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.
