Description

[Technical field]

[0001] The present invention relates to a container with a lid for storing an item. [Background technology]

[0002] A container with lid used for transporting or storing items has a box-shaped container body with an opening that is open at the top. The container with lid has a lid member that is rotatably provided on a side wall of the container body and opens and closes the opening of the container body. A restricting protrusion is formed on the surface of the lid member and restricts horizontal movement of the upper container body relative to the lid member in a stacked configuration (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jpn. Jpn. Published No. 58-049945 Summary of the Invention [Problem to be solved by the invention]

[0004] When the containers are nested with the openings of the container bodies open, the restricting protrusions of the lid members on the upper tier come into contact with the lid members on the lower tier. As a result, the lid members on each tier except the bottom tier spread horizontally such that the leading edges of the lid members are separated from the container body by an amount corresponding to the amount of protrusion of the restricting protrusions of the lid members. This may result in an increase in the horizontal storage space required for multiple nested containers with lids.

[0005] Therefore, one aspect of the present invention aims to reduce the horizontal storage space required for multiple lidded containers in a nested configuration. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, a lidded container according to one aspect of the present invention comprises a container body having an opening that opens upward, and a lid member that is rotatably provided on an upper edge of a side wall of the container body and opens and closes the opening of the container body, and can take a nesting form in which the container bodies are stacked vertically so that the upper container body is accommodated inside the lower container body, and a stacking form in which the container bodies are stacked vertically so that the upper container body is placed on the lower lid member. A restricting protrusion is formed on a surface of the lid member to restrict horizontal movement of the upper container body relative to the lid member in the stacking form, and the lid member has a housing portion on its back side that can house a part of the restricting protrusion of the upper lid member in the nesting form.

[0007] According to the above configuration, in the nesting form, the lid members of each stage other than the bottom stage spread in the horizontal direction so that their leading edge portions move away from the container body. Meanwhile, as described above, the lid members have the accommodation portion on the back side thereof that can accommodate a part of the regulating convex portion of the lid member on the upper stage side in the nesting form. Therefore, in the nesting form, the horizontal spread of the lid members of each stage other than the bottom stage can be suppressed by the amount that the part of the regulating convex portion of the lid member on the upper stage side is accommodated in the accommodation portion of the lid member on the lower stage side. In other words, in the nesting form, the horizontal spread of the lid members of each stage other than the bottom stage can be suppressed by the amount that the part of the regulating convex portion of the lid member on the upper stage side enters inside the contour (side contour) of the lid member on the lower stage side. This allows the horizontal storage space of the multiple lidded containers in the nesting form to be reduced.

[0008] In a lidded container according to one embodiment of the present invention, a reinforcing rib for reinforcing the lid member is formed on the back surface of the lid member, and the storage portion of the lid member may be located on the back surface side of the lid member relative to an end face of the reinforcing rib.

[0009] According to the above configuration, in the nested configuration, the accommodation portion of the cover member can accommodate a part of the restricting protrusion of the upper cover member by an amount that is located on the back surface side of the cover member.

[0010] In one embodiment of the present invention, the reinforcing rib includes an engaging rib that engages with the opening of the container body, the storage portion of the lid member is positioned closer to the center of the lid member than the engaging rib that is located on the side edge side of the lid member, and the lid member may have an opening portion on its back side that opens from the storage portion to the base edge portion of the lid member.

[0011] According to the above configuration, as described above, the lid member has the opening on the back side thereof, which opens from the storage portion to the base end edge of the lid member. Therefore, when removing the lidded container in the nested configuration, the restricting protrusion of the lid member on the upper side is less likely to get caught on the reinforcing rib of the lid member on the lower side. This can improve the efficiency of the removal operation of the lidded container in the nested configuration.

[0012] In one embodiment of the lidded container of the present invention, at least the engaging rib located on the side edge side of the lid member may have a first inclined surface adjacent to the storage portion that is inclined with respect to the back surface of the lid member so as to gradually decrease toward the base edge of the lid member, or the engaging rib located on the base edge side of the lid member may have a second inclined surface adjacent to the storage portion that is inclined with respect to the back surface of the lid member so as to gradually decrease toward the side edge of the lid member (the open portion).

[0013] According to the above configuration, when the containers are nested, the restricting protrusions of the upper lid members are less likely to be caught by the reinforcing ribs of the lower lid members, thereby improving the efficiency of stacking the containers in the nested configuration.

[0014] In one embodiment of the lidded container of the present invention, the storage portion is arranged on each of both side edge portions of the lid member, and the engaging rib located on each side edge portion of the lid member has a first inclined surface adjacent to the storage portion that is inclined relative to the back surface of the lid member so as to gradually lower toward the base edge portion of the lid member, and the engaging rib located on each side edge portion of the lid member may be further away from the base edge portion of the lid member than the reinforcing rib opposite it.

[0015] According to the above-mentioned configuration, as described above, the fitting ribs located on each side edge of the lid member are farther away from the base edge of the lid member than the reinforcing ribs facing them. Therefore, when the nesting configuration is adopted, the restricting protrusions of the lid member on the upper side are less likely to get caught on the reinforcing ribs of the lid member on the lower side. This makes it possible to further increase the work efficiency of stacking the lidded containers in the nesting configuration.

[0016] In one aspect of the present invention, the regulating convex portion of the lid member may have a guide surface that is slidably guided along the base end edge portion of the lid member on the lower side when the lid member assumes the nesting form.

[0017] According to the above configuration, when the containers are in the nested configuration, a part of the restricting protrusion of the upper lid member is stably accommodated in the accommodating portion of the lower lid member, thereby improving the efficiency of stacking the containers in the nested configuration.

[0018] In one embodiment of the present invention, in a lidded container, the base edge portion of the lid member may protrude upwardly relative to the upper edge portion of the side wall portion of the container body when the lid member opens the opening of the container body, and may be placed on the upper edge portion of the side wall portion of the container body when the lid member closes the opening of the container body.

[0019] According to the above-mentioned configuration, as described above, the base end edge of the lid member rests on the upper edge of the side wall of the container body when the lid member closes the opening of the container body. Therefore, in the stacking configuration, it is possible to prevent the lid member from falling due to the load from the upper lidded container. This allows a plurality of the lidded containers to be stored stably in the stacking configuration. Effect of the Invention

[0020] According to one aspect of the present invention, it is possible to reduce the horizontal storage space required for multiple lidded containers in a nested configuration. [Brief description of the drawings]

An intermediate pivotal support 26 is formed between the pair of pivotal supports 24 on the upper side 16u of each lateral side wall 16, and each intermediate pivotal support 26 is formed with a notch 26n.

[0028] (Overview of the cover member 28) As shown in Figures 1 and 2, the lidded container 10 includes a lid member 28 that is rotatably provided on the upper edge portion 16u of each lateral side wall portion 16 and opens and closes the opening 12a of the container body 12. In other words, the lidded container 10 includes a pair of lid members 28 that open and close the opening 12a of the container body 12. Each lid member 28 is made of a resin such as polypropylene, and is formed by injection molding. Note that the material of each lid member 28 is not limited to resin, and may be a metal such as aluminum. Also, the manufacturing method of each lid member 28 is not limited to injection molding, and may be a manufacturing method other than injection molding.

[0029] 1 to 3, each lid member 28 is configured to be switched between an open state and a closed state by its rotational movement. The open state refers to a state in which the opening 12a of the container body 12 is open, and the closed state refers to a state in which the opening 12a of the container body 12 is closed. Note that opening the opening 12a of the container body 12 includes opening a partial area of ​​the opening 12a of the container body 12. Closing the opening 12a of the container body 12 includes closing a partial area of ​​the opening 12a of the container body 12.

[0030] (hinge part 30) 1, 4, and 5, a hinge portion 30 is formed on the base end edge portion 28b of each cover member 28 for rotatably connecting each cover member 28 to the upper side portion 16u of each lateral side wall portion 16. Each hinge portion 30 has a pair of hinge shafts 32 spaced apart in the lateral direction, and a central hinge shaft 34 arranged coaxially between the pair of hinge shafts 32 and extending in the lateral direction. Each hinge shaft 32 is rotatably supported by each pivot support portion 24 of each lateral side wall portion 16, and each intermediate hinge shaft 34 is rotatably supported by each intermediate pivot support portion 26 of each lateral side wall portion 16.

[0031] Both lateral ends of the base end edge 28b of each lid member 28 protrude upward relative to the upper edge 16u of each lateral side wall 16 of the container body 12 when each lid member 28 opens the opening 12a of the container body 12 (see FIG. 2). The base end edge 28b of each lid member 28 rests on the upper edge 16u of the lateral side wall 16 of the container body 12 when each lid member 28 closes the opening 12a of the container body 12 (see FIG. 10).

[0032] (Engagement protrusion 36, engagement recess 38) 1, 4, and 5, an engagement protrusion 36 is formed on the tip edge 28t of each lid member 28 from the horizontal center to one end, protruding toward the opposite side to the hinge portion 30. An engagement recess 38 is formed on the tip edge 28t of each lid member 28 from the horizontal center to the other end, recessed toward the hinge portion 30. The engagement protrusion 36 on one side of each lid member 28 engages with the engagement recess 38 of the other lid member 28 when the pair of lid members 28 close the opening 12a of the container body 12.

[0033] (Reinforcement rib 40, fitting ribs 40A, 40B) 4 and 5, a plurality of reinforcing ribs 40 that reinforce each lid member 28 are formed on the back surface 28r of each lid member 28. The plurality of reinforcing ribs 40 of each lid member 28 include a plurality of fitting ribs 40A, 40B that fit into the opening 12a of the container body 12. The two fitting ribs 40A of each lid member 28 are located on the side of the side edge portion 28s of each lid member 28, and the fitting rib 40B of each lid member 28 is located on the base edge portion 28b of each lid member 28.

[0034] (stacking form, nesting form) As shown in Figures 6 to 10, the lidded container 10 can be in a nesting form or a stacking form as a tiered form. The nesting form is a tiered form in which the container bodies 12 are stacked vertically so that the upper container body 12 is accommodated inside the lower container body 12 (see Figures 6 to 8). The stacking form is a tiered form in which the container bodies 12 are stacked vertically so that the upper container body 12 is placed on the lower closed lid member 28 (see Figures 9 and 10). In the nesting form, the lower ends of the support pieces 22 of the upper container body 12 abut against the upper ends of the upper edge portions 16u of the lateral side walls 16 of the lower container body 12.

[0035] (Regulation protrusion 42) As shown in Figures 4, 9 to 11, restricting protrusions 42 are formed on both lateral ends of the surface 28f of each lid member 28, and each restricting protrusion 42 restricts horizontal movement of the upper container body 12 relative to the lid member 28 in the closed state in the stacked form. Each restricting protrusion 42 of each lid member 28 can abut against the lower end of each protruding portion 20 of the upper container body 12 in the stacked form. Each restricting protrusion 42 of each lid member 28 has a guide surface 42g, and the guide surface 42g is slidably guided by the base end edge portion 28b of the lower lid member 28 when the nesting form is adopted (see Figure 11).

[0036] (Housing section 44) As shown in Figures 2, 5, 8, 11, and 12, each of the cover members 28 has a storage portion 44 at both lateral ends on the back surface 28r side, and each storage portion 44 stores a part of each of the restricting protrusions 42 of the cover member 28 in the open state on the upper side in the nested configuration. In other words, a part of each of the restricting protrusions 42 of each of the cover members 28 is configured to enter inside the contour (side contour) of the cover member 28 on the lower side via each of the storage portions 44 of the cover member 28 on the lower side when viewed from the side in the nested configuration. Note that in Figures 8 and 12, a part of the contour of the cover member 28 is shown by a dashed line.

[0037] 2, 5, and 10, each accommodation portion 44 of each lid member 28 is disposed closer to the lateral center of each lid member 28 than the fitting rib 40A of each lid member 28. Each accommodation portion 44 of each lid member 28 is formed between the fitting rib 40A of each lid member 28 and the reinforcing rib 40C adjacent thereto in the lateral direction. Each accommodation portion 44 of each lid member 28 is located on the back surface 28r side of each lid member 28 with respect to the end face 40e of the reinforcing rib 40 (see FIG. 10).

[0038] (Open part 46) 2 and 5, each of the lid members 28 has an open portion 46 at both lateral ends on the back surface 28r side thereof, the open portion 46 being open from each of the accommodation portions 44 to the base end edge portion 28b of each of the lid members 28. In other words, each of the lid members 28 has an open portion (absent portion) 46 where no reinforcing rib 40 is present from each of the accommodation portions 44 to the base end edge portion 28b of each of the lid members 28, the open portion 46 being open ...

[0039] (1st slope 40Ai etc.) As shown in FIG. 5, each fitting rib 40A of each lid member 28 has a first inclined surface 40Ai at a portion adjacent to each storage portion 44 in the lateral direction. The first inclined surface 40Ai of each fitting rib 40A of each lid member 28 is inclined with respect to the back surface 28r of each lid member 28 so as to gradually lower toward the base end edge portion 28b of each lid member 28. Each fitting rib 40A of each lid member 28 is farther away from the base end edge portion 28b of each lid member 28 than the reinforcing rib 40 (40C) facing each fitting rib 40A. In addition, the fitting rib 40B of each lid member 28 may have a second inclined surface at a portion adjacent to each storage portion. Each second inclined surface of the fitting rib 40B of each lid member 28 is inclined with respect to the back surface 28r of each lid member 28 so as to gradually lower toward the side end edge portion 28s (open portion 46) of each lid member 28. The height of the reinforcing rib 40 including the fitting ribs 40A, 40B is determined by the length of the protrusion from the rear surface 28r of the cover member 28. In other words, when each lid member 28 of the lidded container 10 is in a closed state, each lid member 28 has a top plate portion 48, a restricting protrusion 42 protruding upward from the upper surface of the top plate portion 48, and a reinforcing rib 40 protruding downward from the lower surface of the top plate portion 48. Each lid member 28 has an accommodating portion 44 capable of accommodating a part of the restricting protrusion 42 of the upper lidded container 10 on the top plate portion 48 side relative to the end face 40e of the reinforcing rib 40.

[0040] (Effects of this embodiment) Next, the effects of this embodiment will be described.

[0041] In the nested form, the lid members 28 of each stage except the bottom stage spread horizontally so that their leading edge portions 28t are spaced apart from the container body 12. On the other hand, according to the configuration of the lidded container 10 of this embodiment, as described above, each lid member 28 has a housing portion 44 at both lateral ends of its back surface side that can house a part of each restricting protrusion 42 of the lid member 28 in the open state at the upper stage side in the nested form. Each housing portion 44 of each lid member 28 is located on the back surface 28r side of each lid member 28 with respect to the end face 40e of the reinforcing rib 40. Therefore, in the nested form, each housing portion 44 of each lid member 28 can house a part of each restricting protrusion 42 of the lid member 28 on the upper stage side in abutment to the extent that it is located on the back surface 28r side of each lid member 28.

[0042] As a result, in the nested configuration, the horizontal expansion of the lid members 28 of each stage other than the bottom stage can be suppressed by the amount that a portion of each restricting protrusion 42 of the lid member 28 on the upper stage is accommodated in each accommodation portion 44 of the lid member 28 on the lower stage. In other words, in the nested configuration, the horizontal expansion of the lid members 28 of each stage other than the bottom stage can be suppressed by the amount that a portion of each restricting protrusion 42 of the lid member 28 on the upper stage enters inside the contour (side contour) of the lid member 28 on the lower stage. Therefore, according to this embodiment, the horizontal storage space for multiple lidded containers 10 in the nested configuration can be sufficiently reduced.

[0043] According to the configuration of the lidded container 10 of this embodiment, as described above, each lid member 28 has an opening 46 that opens from each storage portion 44 to the base end edge 28b of each lid member 28 on both lateral ends of the back surface side. Therefore, when removing the lidded container 10 in the nested configuration, each restricting protrusion 42 of the upper lid member 28 is less likely to get caught on the reinforcing rib 40 of the lower lid member 28. Therefore, according to this embodiment, the efficiency of the removal operation of the lidded container 10 in the nested configuration can be improved.

[0044] According to the configuration of the lidded container 10 of this embodiment, as described above, each fitting rib 40A of each lid member 28 has a first inclined surface 40Ai at a portion laterally adjacent to each storage portion 44. Each fitting rib 40A of each lid member 28 is farther away from the base end edge portion 28b of each lid member 28 than the reinforcing rib 40 (40C) facing it. Therefore, when taking the nested form, each restricting protrusion 42 of the lid member 28 on the upper side is less likely to get caught on the reinforcing rib 40 of the lid member 28 on the lower side. Therefore, according to this embodiment, the work efficiency of stacking the lidded containers 10 in the nested form can be improved.

[0045] In particular, according to the configuration of the lidded container 10 of this embodiment, as described above, each of the restricting protrusions 42 of each of the lid members 28 has a guide surface 42g. Therefore, when the containers are in a nested configuration, a portion of each of the restricting protrusions 42 of the upper lid member 28 is stably accommodated in each of the accommodating portions 44 of the lower lid member 28. Therefore, according to this embodiment, the work efficiency of stacking the lidded containers 10 in the nested configuration can be further improved.

[0046] According to the configuration of the lidded container 10 of this embodiment, as described above, the base end edge 28b of each lid member 28 rests on the upper side 16u of the lateral side wall 16 of the container body 12 when each lid member 28 closes the opening 12a of the container body 12. Therefore, in the stacked configuration, it is possible to prevent the lid member 28 from falling due to the load from the lidded container 10 on the upper side. Therefore, according to this embodiment, multiple lidded containers 10 can be stably stored in the stacked configuration.

[0047] (Other embodiments) Instead of two restricting protrusions 42 being formed on the front surface 28f of each lid member 28, one restricting protrusion 42 may be formed. In this case, each lid member 28 has one accommodation portion 44 on the rear surface 28r side. Also, instead of having a pair of lid members 28 that open and close the opening 12a of the container body 12, the lidded container 10 may have one lid member that opens and closes the opening 12a of the container body 12.

[0048] Instead of including the lid member 28 having the reinforcing ribs 40, the lidded container 10 may include a thick lid member that does not have the reinforcing ribs 40. In this case, the thick lid member has a recessed accommodation portion on both lateral ends of the back surface thereof that can accommodate a part of each of the restricting protrusions 42 of the lid member 28 in the open state on the upper side in the nested configuration. In other words, when each of the lid members 28 of the lidded container 10 is in the closed state, the accommodation portion 44 of each of the lid members 28 is recessed in the thickness direction from the lower surface of the top plate portion 48.

[0049] The other embodiments also provide the same advantageous effects as the present embodiment described above.

[0050] (Additional Notes) The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
