[Modes for carrying out the invention]

[0009] Hereinafter, a container storage rack 1 according to an embodiment of the present invention, which is an example of the present invention, will be described with reference to the attached drawings.

[0010] Figure 1 is a plan view of the container storage rack 1 viewed from above. Figure 2 is a side view of the container storage rack 1 taken in the direction of arrow II in Figure 1. Figure 3 is a side view of the container storage rack 1 taken in the direction of arrow III in Figure 1. Figure 4 is a perspective view of the container storage rack 1 according to an embodiment of the present invention, taken from diagonally above. Figure 5 is a cross-sectional view taken along line VV in Figure 1.

[0011] [Container storage rack] The container storage rack 1 is a rack that is applied to a washing machine while containing a plurality of bottomed, open-top cylindrical containers G. In this embodiment, the bottomed, open-top cylindrical container is a cylindrical drinking glass in which the outer diameter of the opening edge is slightly larger than the outer diameter of the bottom. However, this is just an example, and containers of different shapes and materials may be used as bottomed, open-top cylindrical containers. For example, they may be mugs or teacups. In addition, the material may be plastic or ceramic, not just glass. The transparency of the material is not a requirement; it may be transparent, translucent, or opaque.

[0012] The container storage rack 1 comprises a frame 10 that forms the outer shape of the container storage rack 1, and a mounting section 20 on which a plurality of containers G are placed. The containers G are placed on the mounting section 20 with their opening edges facing downwards and their bottoms facing upwards.

[0013] As shown in Figure 1, in this embodiment, the frame 10 is rectangular in shape, having a short side and a long side. Also, as shown in Figures 2 and 3, the frame 10 has a first frame 11 that constitutes the upper part of the frame 10 and a second frame 12 that constitutes the lower part of the frame 10. The frame 10, with the first frame 11 and the second frame 12 superimposed, is fastened to each other, for example, by a locking mechanism consisting of locking claws and locking holes.

[0014] The first frame body 11 and the second frame body 12 can each be formed of an engineering plastic with high durability, water resistance, and heat resistance. As an example, PP (polypropylene) can be used.

[0015] The first frame body 11 has a pair of first short side surfaces 11A and 11B that constitute the short sides, and a pair of first long side surfaces 11C and 11D that constitute the long sides. The second frame body 12 has a pair of second short side surfaces 12A and 12B that constitute the short sides, and a pair of second long side surfaces 12C and 12D that constitute the long sides.

[0016] In the present embodiment, the first frame body 11 includes two protruding portions 13 at predetermined intervals on the first long side surfaces 11C and 11D, respectively. The protruding portions 13 protrude upward from the upper edge portion 11u of the first frame body 11. On the first long side surfaces 11C and 11D, the protruding portions 13 are arranged at positions facing each other. The height h of the protruding portions 13 from the upper edge portion 11u of the first frame body 11 is set to be higher than the end of the container G placed on the placement portion 20.

[0017] The second frame body 12 has a pair of second short side surfaces 12A and 12B that constitute the short sides, and a pair of second long side surfaces 12C and 12D that constitute the long sides. As shown in FIG. 2, a concave portion 14 that is recessed downward from the upper edge portion 12u is formed at a substantially central position of the upper edge portion 12u of the second short side surface 12A in the second frame body 12. Although not shown in FIG. 2, a concave portion similar to the concave portion 14 is also formed at a substantially central position of the upper edge portion 12u of the second short side surface 12B. The placement portion 20 is arranged on the second frame body 12.

[0018] The concave portions 14 are formed at positions facing each other on the second short side surfaces 12A and 12B.

[0019] As shown in FIG. 3, on the upper edge 12u of the second long side surface portion 12C in the second frame body 12, two recesses 15 recessed downward from the upper edge 12u are formed at a predetermined interval. Although not shown in FIG. 3, two recesses similar to the recesses 15 are also formed on the upper edge 12u of the second long side surface portion 12D. The recesses 15 are formed at positions facing each other in the second long side surface portions 12C and 12D.

[0020] In other words, regarding the recess 15, a recess 15 recessed downward from the upper edge 12u is formed in the second long side surface portion 12C, and a convex portion 16 protruding upward is formed in the central region of the recess 15. The convex portion 16 is formed such that the top of the convex portion 16 is flush with the upper edge 12u.

[0021] Since the first frame body 11 and the second frame body 12 have the above-described configuration, by overlapping the lower surface of the first frame body 11 and the upper edge 12u of the second frame body 12, a short side surface opening 17 due to the recess 14 is formed in the short side surface portion of the frame body 10, and a long side surface opening 18 due to the recess 15 is formed in the long side surface portion.

[0022] The short side surface opening 17 and the long side surface opening 18 allow the inflow of the cleaning liquid from the side surface portion of the frame body 10, respectively. The shapes and sizes of the recess 14 and the recess 15 only need to allow the cleaning liquid to flow in, and are not limited to the illustrated shapes and sizes.

[0023] Also, as shown in FIGS. 1 and 4, the second frame body 12 is located below the placement portion 20 and includes a reinforcing portion 12E for reinforcing the second frame body 12. In the present embodiment, the reinforcing portion 12E is composed of a plurality of reinforcing members 12e. Further, the reinforcing portion 12E has a frame body opening 12h that communicates the outside and the inside of the frame body 10.

[0024] The plurality of reinforcing members 12e are each supported between the second long side surface portions 12C and 12D below the columnar member 23 that constitutes the extending portion 21. The frame body opening 12h is a gap formed between the plurality of reinforcing members 12e.

[0025] The second frame 12, by being equipped with multiple reinforcing members 12e, has increased strength against twisting of the second frame 12 and against stress acting in the direction that brings the second long side portions 12C and 12D closer together.

[0026] As shown in Figures 1 and 4, the mounting section 20 has an extension 21 extending in one direction from the frame 10 and an opening 22 formed adjacent to the extension 21.

[0027] In this embodiment, the extension portion 21 is composed of a plurality of cylindrical members 23 (23a, 23b, 23c, 23d, 23e, 23f) that extend in the longitudinal direction of the frame 10 and have a substantially circular cross-section perpendicular to the longitudinal direction. Hereinafter, when the cylindrical members constituting the extension portion 21 are not distinguished from each other, they will be referred to as cylindrical members 23.

[0028] A single cylindrical member 23 can support the opening edge of the container G at at least two points. In this embodiment, the extension 21 is composed of two cylindrical members 23 as a pair.

[0029] That is, as shown in Figure 4, the mounting section 20 has a first lane L1 made of cylindrical members 23a and 23b, a second lane L2 made of cylindrical members 23c and 23d, and a third lane L3 made of cylindrical members 23e and 23f. In each lane, the opening edge of the container G can be supported at four points by a pair of cylindrical members 23. In this embodiment, the space between the cylindrical members 23 that constitute the extension section 21 constitutes the opening 22.

[0030] Furthermore, in this embodiment, the container storage rack 1 further includes a partition 24 that extends in one direction within the frame 10 and restricts the movement of multiple containers G in a direction intersecting the direction in which the extension portion 21 extends.

[0031] As shown in Figure 4, the partitions 24 are arranged in the short-side direction at intervals that match the outer diameter of the container G. In this embodiment, the partitions 24 include a first partition 25 that separates the first lane L1 and the second lane L2 along the longitudinal direction, and a second partition 26 that separates the second lane L2 and the third lane L3 along the longitudinal direction.

[0032] The first partition section 25 has an upper partition member 25u that abuts against the upper side of the placed container G, and a lower partition member 25b that abuts against the lower side of the container G. Similarly, the second partition section 26 has an upper partition member 26u and a lower partition member 26b (see Figures 5 and 6).

[0033] The upper partition members 25u and 26u are located on the first frame 11, and the lower partition members 25b and 26b are located on the second frame 12.

[0034] The upper partition members 25u, 26u and the lower partition members 25b, 26b are all composed of multiple cylindrical members with a substantially circular cross-section, similar to the extension 21. In the following, when the upper partition members 25u, 26u and the lower partition members 25b, 26b are not distinguished from each other, they will simply be referred to as the partition 24.

[0035] In this embodiment, the container storage rack 1 is configured as described above, with a mounting section consisting of a plurality of cylindrical members 23 and partition sections 24, so that a plurality of containers G can be placed in series along the direction in which the extension section 21 and partition sections 24 extend.

[0036] In this embodiment, cylindrical members 23 (23a, 23b, 23c, 23d, 23e, 23f) and partitions 24 (upper partition members 25u, 26u, lower partition members 25b, 26b) can all be cylindrical members having the same diameter and length.

[0037] In this embodiment, the cylindrical members 23 (23a, 23b, 23c, 23d, 23e, 23f) and the partitions 24 (upper partition members 25u, 26u, lower partition members 25b, 26b) are configured to be detachably attached to the frame 10.

[0038] Figure 6 is a cross-sectional view of the container storage rack 1 along the line VI-VI in Figure 1. As shown in Figure 6, the first frame 11 has a plurality of U-shaped support portions 31a that are open upwards on the inside of the first short side portion 11A. The support portions 31a support one end of the upper partition member 25u and one end of the upper partition member 26u.

[0039] Furthermore, the first frame 11 has a support portion 31b on the inside of the first short side portion 11B that faces the first short side portion 11A, which supports the other end of the upper partition member 25u and the other end of the upper partition member 26u (see Figure 5). The support portion 31b is provided in the first short side portion 11B at a position where the upper partition members 25u and 26u are horizontally attached to the frame 10.

[0040] Furthermore, the second frame 12 has a plurality of U-shaped support portions 32a on the inside of the second short side portion 12A that are open upward. Each of the support portions 32a supports one end of the lower partition member 25b and one end of the lower partition member 26b.

[0041] Furthermore, the second frame 12 has a support portion 32b on the inside of the second short side portion 12B that faces the second short side portion 12A, which supports the other end of the lower partition member 25b and the other end of the lower partition member 26b (see Figure 5). The support portion 32b is provided in the second short side portion 12B at a position where the lower partition members 25b and 26b are horizontally attached to the frame 10.

[0042] Furthermore, the second frame 12 has a plurality of U-shaped support portions 33a on the inside of the second short side portion 12A that are open upward. Each support portion 33a supports one end of the cylindrical member 23 (23a, 23b, 23c, 23d, 23e, 23f).

[0043] The second frame 12 has a support portion 33b on the inside of the second short side portion 12B that faces the second short side portion 12A, which supports the other end of the cylindrical member 23 (23a, 23b, 23c, 23d, 23e, 23f) (see Figure 5). The support portion 33b is provided on the second short side portion 12B at a position where the cylindrical member 23 (23a, 23b, 23c, 23d, 23e, 23f) is horizontally attached to the frame 10.

[0044] The U-shaped support portions 31a, 31b, 32a, 32b, and 33a, 33b are each formed such that their open portions abut the outer diameters of the cylindrical members 23 (23a, 23b, 23c, 23d, 23e, 23f) and the partition portions 24 (upper partition members 25u, 26u, lower partition members 25b, 26b), or they are formed to be slightly narrower than the outer diameters.

[0045] Support parts 31a, 31b, support parts 32a, 32b, and support parts 33a, 33b can be integrally molded with the first frame 11 or the second frame 12, for example, by injection molding. Since each of the support parts 31a, 31b, support parts 32a, 32b, and support parts 33a, 33b can be realized with the same structure, the following explanation will use support part 31 as an example.

[0046] When the end of the partition portion 24 (upper partition member 25u) is positioned along the second short side portion 12A and pushed toward the closed portion of the support portion 31a, the flexibility of the frame 10 and the materials forming the support portion 31a causes the open portion of the support portion 31a to deform to follow the outer shape of the end of the upper partition member 25u. Once the end of the upper partition member 25u is inside the U-shape, the open portion tries to return to its original position, and this biasing force holds the end of the upper partition member 25u inside the U-shape.

[0047] Furthermore, as shown in Figure 4, the frame 10 (first frame 11) has projections 11P on its first short side portions 11A and 11B at positions corresponding to the first lane L1, the second lane L2, and the third lane L3, respectively.

[0048] In this embodiment, the projection 11P is located above a certain portion on the side surface of the end portion of the extension 21 in the direction of extension of the extension 21, and is formed as a convex portion that protrudes inward from the frame 10 more than that certain portion. The projection 11P is configured to contact the upper side of the container G, i.e., the bottom side of the container G, when the container G is placed on the mounting portion 20 (extension 21) with its opening edge facing downward.

[0049] <Effects and Effects> The container storage rack 1 according to this embodiment comprises a substantially rectangular frame 10 and a mounting section 20 arranged on the frame 10. The mounting section 20 is composed of an extension section 21 made up of a plurality of cylindrical members 23 extending in the longitudinal direction of the frame 10, and openings 22 between the cylindrical members 23.

[0050] Furthermore, the frame 10 comprises a first frame 11 that constitutes the upper part of the frame 10 and a second frame 12 that constitutes the lower part of the frame 10. The second frame 12 is provided with a plurality of reinforcing members 12e at positions that do not interfere with the container G placed on the mounting section 20, that is, on the lower side of the mounting section 20, and a frame opening 12h is formed between the plurality of reinforcing members 12e.

[0051] At the bottom surface of the frame 10, the container G is exposed through the opening 22 and the frame opening 12h.

[0052] Container G is placed on the mounting section 20 with its opening edge facing downwards and its bottom facing upwards, in an inverted state compared to when it is in use, and in contact with the cylindrical member 23 which serves as the extension 21. This allows the cleaning liquid that has passed through the opening 22 in the mounting section 20 and the frame opening 12h to enter the container G from the opening edge toward the bottom, thereby cleaning the inside of container G.

[0053] In the container storage rack 1 according to this embodiment, the mounting section 20 can support the opening edge of the container G at four points by a set of cylindrical members 23. Therefore, the container G is stably supported, and the area of ​​the contact surface between the cylindrical members 23 and the container G can be reduced.

[0054] The contact area between the opening edge of container G and the cylindrical member 23 is small, and the contact surface is curved. Therefore, the liquid that washes the inside of container G and returns to the opening edge side does not remain at the contact point, but easily drips down the outer surface of the cylindrical member 23. Consequently, the container storage rack 1 has good water drainage.

[0055] Furthermore, the container storage rack 1 is equipped with partitions 24 that restrict the movement of multiple containers G in a direction intersecting the direction in which the cylindrical members 23 constituting the extended portion 21 extend. This allows multiple containers G to be neatly arranged in a single line in each lane, and prevents containers G lined up in adjacent lanes from coming into contact with each other.

[0056] Figure 7 is an explanatory diagram illustrating the movement of container G remaining in container storage rack 1 when container G is removed from container storage rack 1. The upper part of Figure 7 shows container G being removed from container storage rack 1, and the lower part shows the state after container G has been removed from container storage rack 1. In Figure 7, for explanatory purposes, containers G are labeled with sub-numbers such as G1, G2, G3 to distinguish them.

[0057] As described above, in the container storage rack 1 according to this embodiment, the area of ​​the contact surface between the cylindrical member 23 and the container G can be reduced, so frictional resistance is less likely to occur between the container G and the cylindrical member 23, and the container G can easily slide on the surface of the cylindrical member 23.

[0058] Therefore, as shown in Figure 7, if the container storage rack 1 is installed with one side, the first short side portion 11A, lower and the other side, the first short side portion 11B, higher, then, as shown in the upper diagram of Figure 7, when container G1 is removed from the first short side portion 11A, the remaining containers G2, G3, etc., which are placed in series and touching each other, will slide towards the lower side due to their own weight, as shown in the lower diagram of Figure 7. As a result, the gap created when container G1 is removed is naturally filled by the remaining containers G2, G3, etc.

[0059] A suitable setting for the container storage rack 1 according to this embodiment is a family restaurant. In family restaurants, it is common for customers to take glasses from a glass stand themselves and pour their own beverages into the glasses. In such a setting, multiple glass racks containing glasses are provided at the beverage serving area.

[0060] With conventional container storage racks, users often haphazardly pick up glasses from easily accessible positions on the glass rack. Furthermore, the glass racks are stored in dedicated shelves at beverage service areas. Therefore, employees had to go to the beverage service area, pull the glass racks out of the shelves, and visually check the remaining number of glasses.

[0061] In contrast, according to the container storage rack 1 of this embodiment, the containers G remaining in the container storage rack 1 are moved towards the first short side portion 11A, making it easier to remove the containers G from the first short side portion 11A.

[0062] Furthermore, since the containers G remaining in the container storage rack 1 are always positioned towards the first short side portion 11A, it becomes easier to visually check the presence or absence of containers G in the container storage rack 1 without having to, for example, pull the container storage rack 1 out from the rack's shelf. As a result, employees can easily visually check the presence or absence of containers G from a distance without having to go to the front of the container storage rack 1. Therefore, according to the container storage rack 1 of this embodiment, the work required for employees to check the remaining number of containers G is simplified, thereby reducing the workload on employees.

[0063] Furthermore, with the container storage rack 1 according to this embodiment, the containers G remaining in the container storage rack 1 are positioned towards the first short side portion 11A. Therefore, compared to conventional container storage racks where users randomly and carelessly take out glasses, it becomes more difficult to return a container G that has been taken out of the container storage rack 1 back into the container storage rack 1. Consequently, the container storage rack 1 according to this embodiment reduces the possibility of a user touching multiple containers G, and is also more hygienic.

[0064] Based on the above, the container storage rack 1 can be used in a washing machine, and the containers G can be easily removed, thereby improving the convenience of the container storage rack. In addition, this can reduce the workload on employees and enable efficient store operations.

[0065] The first frame 11 constituting the container storage rack 1 has projections 11P at positions corresponding to the first lane L1, second lane L2, and third lane L3 on the first short side portions 11A and 11B, respectively, which are configured to contact the upper part of a container G when it is placed on the mounting portion 20 (extended portion 21) with its opening edge facing downwards, i.e., the bottom side of the container G.

[0066] Since container G has its center of gravity towards the bottom rather than the sides, when placed upside down, the center of gravity of container G is located at the bottom, i.e., at the top when it is placed upright.

[0067] In this state, if the container G slides along the cylindrical member 23 and the opening edge located on the lower side comes into contact with the second short side portion 12A of the second frame 12, a moment is likely to act that causes the bottom side to continue moving in the sliding direction, and as a result, the container G may tip over.

[0068] On the other hand, in the container storage rack 1 according to this embodiment, as shown in the lower diagram of Figure 7, the bottom side of the container G first comes into contact with the projection 11P, thereby preventing tipping due to moment.

[0069] In the container storage rack 1 according to this embodiment, the second frame 12 has a plurality of reinforcing members 12e, thereby increasing the strength of the second frame 12 against twisting and stress acting in the direction that brings the second long side portions 12C and 12D closer together.

[0070] Furthermore, the container storage rack 1 is provided with two overhangs 13 extending upward from the upper edge 11u of the first frame 11, at predetermined intervals from the first long side portions 11C and 11D of the first frame 11, and the height h of the overhangs 13 extending from the upper edge 11u is set to a height that exceeds the edge of the container G placed on the mounting portion 20.

[0071] As a result, even when the container storage racks 1 are stacked, they do not interfere with the containers G placed inside. Therefore, the convenience of handling the container storage racks 1 within the store, such as transportation and collection by employees, can be improved.

[0072] In this embodiment, the cylindrical members 23 (23a, 23b, 23c, 23d, 23e, 23f) and partitions 24 (upper partition members 25u, 26u, lower partition members 25b, 26b) that constitute the extension 21 are configured to be detachable from the frame 10 (first frame 11 and second frame 12). Therefore, containers G can be placed on the rack and subjected to a washing machine, and the container storage rack 1 itself can be disassembled and cleaned, making it hygienic.

[0073] Furthermore, if the cylindrical members 23 and partitions 24 are all made of cylindrical members having the same diameter and length, the process of disassembling, cleaning, and then reassembling can be easily carried out.

[0074] Furthermore, in the container storage rack 1, the lower surface of the first frame 11 and the upper edge 12u of the second frame 12 are overlapped, so that a short side opening 17 is formed on the short side of the frame 10 and a long side opening 18 is formed on the long side.

[0075] This allows the cleaning solution to penetrate the inside of the frame 10 through its side walls, thereby improving cleaning efficiency and reducing the weight of the frame 10. Consequently, the convenience of the container storage rack 1 can be improved.

[0076] [Rack System] Next, we will describe the rack system 100 to which the container storage rack 1 is applied.

[0077] Figure 8 is an explanatory diagram illustrating a rack system 100 consisting of multiple container storage racks 1, 2, and 3, and shelves 90 on which each of the container storage racks is set.

[0078] The shelf 90 comprises a shelf body 91 and holding parts 92, 93, and 94 for holding the container storage rack 1. Although not shown, the holding parts 92, 93, and 94 are equipped with an angle adjustment mechanism that allows for variable mounting angles to the shelf body 91, so that one end of the container storage racks 1, 2, and 3 can be set in an inclined state where it is lower than the other end.

[0079] As an example, the holding sections 92, 93, and 94 are each set at an angle of 10 degrees from the horizontal plane. This allows the containers G to slide appropriately within the mounting section 20 in the container storage rack 1 set in the holding sections 92, 93, and 94.

[0080] By using a shelf 90 with inclined holding sections 92, 93, and 94 instead of inclined mounting section 20 of the container storage rack 1, the size of the container storage rack 1 can be reduced compared to an example where the mounting section of the container storage rack is inclined. This reduces the volume occupied by the container storage rack 1 inside the dishwasher.

[0081] [Other embodiments] Although this embodiment has been described above, the above embodiment is merely one example of how the present invention can be applied, and it is not intended to limit the technical scope of the present invention to the specific configuration of the above embodiment.

[0082] The container G applied to the container storage rack 1 according to this embodiment is not limited to a cylindrical beverage glass in which the outer diameter of the opening rim is slightly larger than the outer diameter of the bottom. For example, it may be a mug or a teacup. In addition, the material may be plastic or ceramic, not glass. The transparency of the material is not limited and may be transparent, translucent, or opaque.

[0083] In the container storage rack 1, the first frame 11 and the second frame 12 may be integrally molded. In addition, the extension 21 (cylindrical member 23) and partition 24 (upper partition members 25u, 26u and lower partition members 25b, 26b), which were previously described as separable, may both be integrally molded with respect to the frame 10.

[0084] In the mounting section 20, the extension section 21 is described as being composed of a cylindrical member 23. However, the extension section is not limited to a cylindrical member, as long as the area of ​​the contact surface with the opening edge of the container G is as small as possible. For example, it may be a triangular prism member. In this case, it is preferable to position it so that the vertex of the triangle in the cross-section contacts the opening edge of the container G.

[0085] The projection 11P is located above a certain portion on the side surface of the end of the extension 21 and only needs to protrude inward from the frame 10 beyond that certain portion. For this reason, instead of the projection 11P protruding inward, a recess may be formed on the first short side surface 11A in an area other than the area on the inner surface of the first frame 11 corresponding to the bottom of the container G, with the recess facing outward. This allows the inner surface of the first short side surface 11A to function as a projection and contact the bottom of the container G when the side surface of the container G approaches the recess of the first short side surface 11A, thereby achieving the same effect as the projection 11P.

[0086] Although the first frame 11 is described as having two protruding portions 13 at predetermined intervals on the first long side portions 11C and 11D, the size and number of the protruding portions 13 along the side direction are not limited to those shown in the figures.

[0087] Alternatively, a first frame with a modified overhang height may be prepared, allowing the combination of the first and second frames to be appropriately changed according to the size of the container G to which it is applied.

[0088] Alternatively, instead of placing an overhang on the first frame, the side portion of the first frame may be pre-formed to be higher than the height of the container G placed on the mounting portion 20, and a recess may be formed inward from the side portion. This provides the equivalent effect of weight reduction through material removal and preventing the stacked container storage rack from interfering with the container G.

[0089] In this embodiment, the extension portion 21 is made up of two cylindrical members 23 with a substantially circular cross-section. That is, the container G is supported at four points at its opening edge. Alternatively, if the partition portion 24 can support the container G without it shifting in the short-side direction, the container G may be configured to be supported at two points by a single cylindrical member 23.

[0090] In the container storage rack 1, the number of lanes on which containers G are placed is not limited to three. The size of the container storage rack 1 is determined according to the size of the containers G and the internal volume of the dishwasher. [Explanation of Symbols]
