Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, there are containers of different sizes. Therefore, it is difficult to use one storage case lid for containers of different sizes. For this reason, it is necessary to prepare a plurality of storage case lids according to the sizes of the containers of different sizes, and there is room for improvement from this point of view.

[0005] An object of the present invention is to provide a storage case lid that can be used for storage cases of different sizes.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention proposes the following means. (1) The storage case lid according to the present invention covers an opening provided at the upper end of a storage case and is a storage case lid capable of stacking other storage cases. It has a lid body that covers the opening, a raised portion provided along the outer periphery of the lid body, a first vertical wall protruding downward from the outer wall of the raised portion, and a second vertical wall protruding downward from a position away from the center side of the lid body with respect to the inner wall of the raised portion.

[0007] Here, for example, among the storage cases, there are large storage cases and small storage cases with different sizes. Therefore, the first vertical wall is protruded downward from the outer wall of the raised portion, and the second vertical wall is protruded downward from a position away from the center side of the lid body with respect to the inner wall of the raised portion.

[0008] Thus, when the storage case lid is used for a large storage case (hereinafter sometimes referred to as a large storage case), the upper end portion of the large storage case can be arranged inside with respect to the first vertical wall. Thereby, it is possible to prevent the storage case lid from coming off from the upper end portion of the large storage case, and the storage case lid can be stably held at the upper end portion of the large storage case.

[0009] Also, when the storage case lid is used for a small storage case (hereinafter sometimes referred to as a small storage case), the upper end portion of the small storage case can be arranged inside with respect to the second vertical wall. Thereby, it is possible to prevent the storage case lid from coming off from the upper end portion of the small storage case, and the storage case lid can be stably held at the upper end portion of the small storage case. Alternatively, when the upper end portion of the small storage case is arranged outside with respect to the second vertical wall, the second vertical wall can prevent the storage case lid from coming off from the upper end portion of the small storage case, and the storage case lid can be stably held at the upper end portion of the small storage case.

[0010] In this way, by projecting the first vertical wall downward and the second vertical wall downward, the storage case lid can be made to fit storage cases of different sizes, such as large storage cases and small storage cases. In other words, the storage case lid can be made to fit containers of various sizes by changing the contact (contacting) locations with large containers and small containers, and can be prevented from moving more than necessary with respect to the container.

[0011] Furthermore, it is possible to stack other storage cases on the storage case lid. Here, legs protrude downward from the bottom of the storage case. Therefore, in a state where other storage cases are stacked on the storage case lid, the legs can be arranged inside with respect to the inner wall of the raised portion. Thereby, it is possible to prevent other storage cases from coming off the storage case lid and stably hold other storage cases on the storage case lid.

[0012] (2) In the above aspect, the second vertical wall may be arranged inside the corner of the lid body and provided along the corner.

[0013] According to this configuration, the second vertical wall is arranged inside the corner and provided along the corner. Therefore, the second vertical wall can be formed in a curved shape in plan view. Thereby, the rigidity (strength) of the second vertical wall can be ensured. Therefore, the storage case lid can be held more stably at the upper end of the small storage case.

[0014] Also, by providing the second vertical wall at the corner of the lid body, the weight of the storage case lid can be reduced compared to, for example, the case where the second vertical wall is provided around the entire circumference of the lid body. Furthermore, the raw materials used in manufacturing the storage case lid can be reduced.

[0015] (3) In the above aspect, the first vertical wall may have a restricting portion that is recessed toward the lid body side.

[0016] According to this configuration, the regulating portion of the first upright wall is recessed toward the lid body side. Therefore, the regulating portion can be brought into contact with or close to the upper end portion of the large storage case. Thereby, it is possible to suppress rattling of the storage case lid at the upper end portion of the large storage case. Further, by recessing the regulating portion in the first upright wall, the rigidity (strength) of the second upright wall can be ensured. Thereby, the storage case lid can be held more stably at the upper end portion of the large storage case.

[0017] (4) In the above aspect, the raised portion may have a groove portion through which a binding member wound around the outer periphery of the storage case passes.

[0018] According to this configuration, a groove portion is provided in the raised portion, and a binding member (for example, a binding belt) wound around the outer periphery of the storage case is passed through the groove portion. Therefore, the binding member can be held at a predetermined position of the storage case lid. Thereby, the storage case lid can be easily fixed to the upper end portion of the storage case with the binding member.

Effects of the Invention

[0019] According to the present invention, it is possible to cope with storage cases of different sizes.

Mode for Carrying Out the Invention

[0021] Hereinafter, with reference to the drawings, a storage case lid according to an embodiment of the present invention will be described. In the embodiment, a container is described as an example of the storage case, but the storage case is not limited to the container. Hereinafter, the opening side of the container will be described as upward, and the bottom side of the container will be described as downward. Also, the back side of the storage case lid will be described as downward, and the front side of the storage case lid will be described as upward.

[0022] FIG. 1 is a perspective view showing a state where the storage case lid of the embodiment is used for a large container. As shown in FIG. 1, the storage case lid 10 is disposed, for example, at the upper end of a container as a storage case. The container is formed of, for example, a resin material. Here, among the containers, there are a large container 100 and a small container 200 (see FIG. 7) having different sizes. The large container 100 is formed with a smaller "length", "width", and "height" than the small container 200. Hereinafter, the large container 100 may be referred to as the "large container 100". Also, the small container 200 may be referred to as the "small container 200".

[0023] The large container 100 has, for example, a bottom 101 formed in a rectangular shape, and side walls 102 are raised from the four sides of the bottom 101. Further, the large container 100 has legs 104 (see FIG. 6) protruding downward from the four corners 101a of the bottom 101. Furthermore, the large container 100 is formed in a box shape with an opening 106 (see FIG. 6) provided at the upper end 105.

[0024] The large container 100 is used, for example, as a storage case for transporting and storing harvested products such as vegetables and fruits. Alternatively, the large container 100 is used, for example, as a storage case for storing tools used in agricultural work. Further, in the large container 100, for example, the bottom 101 and the side walls 102 are formed in a mesh shape. By forming the bottom 101 and the side walls 102 in a mesh shape, it is possible to maintain the freshness of the agricultural products stored in the large container 100 and reduce the weight during transportation of the agricultural products. A storage case lid 10 is disposed at the upper end portion 105 of the large container 100.

[0025] FIG. 2 is a perspective view of the storage case lid of the embodiment as viewed from below. FIG. 3 is a cross-sectional view of the storage case lid of FIG. 2 taken along line III-III. As shown in FIGS. 1 to 3, the storage case lid 10 is integrally formed of, for example, a resin material. The storage case lid 10 includes a lid body 12, a raised portion 13, a first standing wall 14, a second standing wall 15, a reinforcing rib 16, and a groove portion 17.

[0026] The lid body 12 is disposed so as to cover the opening 106 (see FIG. 6) in a state where the storage case lid 10 is disposed at the upper end portion 105 (see FIG. 6) of the large container 100. The lid body 12 is formed in a rectangular shape so as to cover the opening 106 in plan view. Another large container 120 (see FIG. 6) is placed on the lid body 12. Specifically, the legs 122 (see FIG. 6) at the bottom 121 of another large container 120 are placed on the lid body 12. The lid body 12 has four corner bodies (corners) 12a. The four corner bodies 12a are formed in a curved shape protruding outward in plan view. A raised portion 13 is provided along the outer periphery of the lid body 12.

[0027] The raised portion 13 is formed in a rectangular frame shape in plan view by a pair of long sides 21 and a pair of short sides 22. The raised portion 13 also has an inner wall 25, a top portion 26, and an outer wall 27. The inner wall 25 is provided along the outer periphery of the lid body 12. The inner wall 25 is raised upward from the outer periphery of the lid body 12.

[0028] The top 26 is provided along the upper side of the inner wall 25. The top 26 is horizontally projected outward from the upper side of the inner wall 25 and is formed flat. The outer wall 27 is provided along the outer periphery of the top 26. The outer wall 27 is projected outward in an inclined manner downward from the outer periphery of the top 26. The first standing wall 14 is provided along the lower side of the outer wall 27.

[0029] The first standing wall 14 is projected downward from the lower side of the outer wall 27 and is formed in a rectangular frame shape in plan view. The first standing wall 14 has four corner standing walls 31 and four regulating portions 32. The four corner standing walls 31 are provided at four corner outer walls 27a of the outer wall 27. The four corner standing walls 31 are formed in a curved shape protruding outward in plan view.

[0030] The four regulating portions 32 are linearly provided between adjacent corner standing walls 31 and corner standing walls 31. That is, the regulating portion 32 connects adjacent corner standing walls 31 and corner standing walls 31. The regulating portion 32 is formed so as to be recessed stepwise toward the lid body 12 side with respect to the corner standing wall 31.

[0031] The four second standing walls 15 are projected downward from a position 12b away from the center side of the lid body 12 with respect to the inner wall 25 of the raised portion 13. The four second standing walls 15 are arranged inside the four corner bodies 12a of the lid body 12 and are respectively provided along the four corner bodies 12a. Further, the second standing wall 15 is arranged along the corner standing wall 31 inside the corner standing wall 31. Therefore, the second standing wall 15 is formed in a curved shape protruding outward in plan view.

[0032] Between adjacent second vertical walls 15 and 15, a rib 34 is provided linearly. That is, the rib 34 connects adjacent second vertical walls 15 and 15. The rib 34 projects downward from a position away from the center side of the lid body 12 with respect to the inner wall 25 of the raised portion 13. The rib 34 is arranged along the restricting portion 32 inside the restricting portion 32.

[0033] FIG. 4 is a cross-sectional view of the storage case lid of FIG. 2 taken along line IV-IV and broken. As shown in FIGS. 2 to 4, a reinforcing rib 16 is provided along the inner surface of the raised portion 13. The reinforcing rib 16 has, for example, a plurality of first reinforcing ribs 41 and a plurality of second reinforcing ribs 42. The plurality of first reinforcing ribs 41 are provided at intervals in the circumferential direction between the second vertical wall 15 and the corner vertical wall 31. The first reinforcing rib 41 is arranged so as to be orthogonal to the corner vertical wall 31 and the corner vertical wall 31 in plan view. The upper side 41a of the first reinforcing rib 41 is integrally formed along the inner surface of the raised portion 13 and the inner surface along the outer periphery of the lid body 12. Further, the outer side 41b of the first reinforcing rib 41 is integrally formed on the upper inner surface of the corner vertical wall 31. Furthermore, the inner side 41c of the first reinforcing rib 41 is integrally formed on the upper outer surface of the second vertical wall 15. Also, the lower side 41d of the first reinforcing rib 41 is formed flat.

[0034] The plurality of second reinforcing ribs 42 are provided at intervals in the circumferential direction between the rib 34 and the restricting portion 32. The second reinforcing rib 42 is arranged so as to be orthogonal to the rib 34 and the restricting portion 32 in plan view. The second reinforcing rib 42, like the first reinforcing rib 41, has its upper side integrally formed along the inner surface of the raised portion 13 and the inner surface along the outer periphery of the lid body 12. Also, the outer side of the second reinforcing rib 42 is integrally formed on the upper inner surface of the restricting portion 32. Furthermore, the inner side of the second reinforcing rib 42, like the first reinforcing rib 41, is integrally formed on the upper outer surface of the second vertical wall 15. Also, the lower side 42a of the second reinforcing rib 42 is formed flat.

[0035] The lower sides 41d of the plurality of first reinforcing ribs 41 and the lower sides 42a of the plurality of second reinforcing ribs 42 are formed flat and arranged at the same height. Also, the lower sides 41d of the plurality of first reinforcing ribs 41 and the lower sides 42a of the plurality of second reinforcing ribs 42 are positioned above the lower ends 14a of the first vertical wall 14 and the lower ends 15a of the second vertical wall 15.

[0036] As shown in FIGS. 1 and 3, the raised portion 13 has a groove portion 17. The groove portion 17 has, for example, a pair of first groove portions 51, a pair of second groove portions 52, and a pair of third groove portions 53. The pair of first groove portions 51 are provided closer to one short side 22 on the pair of long sides 21 of the raised portion 13. The pair of first groove portions 51 are formed in a concave shape. Also, the groove bottoms 51a of the pair of first groove portions 51 are formed flush with the surface of the lid body 12. A bundling belt (bundling member) 60 wound around the outer periphery of the large container 100 is passed through the pair of first groove portions 51.

[0037] The pair of second groove portions 52 are provided closer to the other short side 22 on the pair of long sides 21 of the raised portion 13. The pair of second groove portions 52 are formed in a concave shape. The groove bottoms 52a of the pair of second groove portions 52 are formed flush with the surface of the lid body 12. A bundling belt 60 wound around the outer periphery of the large container 100 is passed through the pair of second groove portions 52.

[0038] The pair of third groove portions 53 are provided at the center on the pair of short sides 22 of the raised portion 13. The pair of third groove portions 53 are formed in a concave shape. The groove bottoms 53a of the pair of third groove portions 53 are formed flush with the surface of the lid body 12. A bundling belt 60 wound around the outer periphery of the large container 100 is passed through the pair of third groove portions 53.

[0039] The closing belt 60 is passed through, for example, a pair of first groove portions 51 and a pair of second groove portions 52 selected from a pair of first groove portions 51, a pair of second groove portions 52, and a pair of third groove portions 53 in a state where the storage case lid 10 is arranged at the upper end portion 105 of the large container 100. Alternatively, the closing belt 60 is passed through, for example, a pair of third groove portions 53 selected from a pair of first groove portions 51, a pair of second groove portions 52, and a pair of third groove portions 53. In addition, the closing belt 60 is also applicable to the storage case lid 10 arranged at the upper end portion 205 of the small container 200 shown in FIG. 7. In the embodiment, the closing belt 60 is described as an example of the binding member, but the binding member is not limited to the closing belt 60. As another example, other binding members such as a binding string may be used.

[0040] Next, an example of using the storage case lid 10 for the large container 100 will be described with reference to FIGS. 1, 5, and 6. FIG. 5 is a perspective view for explaining an example of using the storage case lid of the embodiment for a large container. FIG. 6 is a cross-sectional view for explaining an example of using the storage case lid of the embodiment for a large container.

[0041] As shown in FIGS. 1, 5, and 6, the storage case lid 10 is arranged from above at the upper end portion 105 of the large container 100. The lower sides 41d (see FIG. 4) of the plurality of first reinforcing ribs 41 and the lower sides 42a of the plurality of second reinforcing ribs 42 are placed on the upper end portion 105 of the large container 100. In addition, the four regulating portions 32 contact or are close to the outer periphery 105a of the upper end portion 105. Thereby, the four regulating portions 32 can suppress the storage case lid 10 from rattling with respect to the upper end portion 105 of the large container 100. In this state, the opening 106 of the upper end portion 105 in the large container 100 can be covered with the storage case lid 10.

[0042] Further, another large container (storage case) 120 can be stacked on the storage case lid 10 disposed at the upper end portion 105 of the large container 100. The other large container 120 is configured in the same manner as the large container 100. That is, legs 122 protrude downward from the bottom 121 of the other large container 120. When the other large container 120 is stacked on the storage case lid 10, the legs 122 are placed on the lid body 12 of the storage case lid 10. The legs 122 protrude downward from the bottom 121. The legs 122 are disposed inside the raised portion 13 when placed on the lid body 12. Thereby, it is possible to prevent the other large container 120 from coming off the storage case lid 10.

[0043] Next, an example in which the portion where the storage case lid 10 contacts or approaches the container differs depending on the size of the container will be described with reference to FIGS. 7 to 9. For example, in the case of the small container shown in FIG. 7, the second standing wall 15 contacts or approaches the container. In the case of the other large container shown in FIG. 8, the first standing wall 14 contacts or approaches the container. In the case of the other small container shown in FIG. 9, the second standing wall 15 contacts or approaches the container. Hereinafter, the examples of FIGS. 7 to 9 will be described in detail.

[0044] First, an example of using the storage case lid 10 for the small container 200 will be described with reference to FIG. 7. FIG. 7 is a cross-sectional view for explaining an example of using the storage case lid of the embodiment for a small container.

[0045] As shown in FIG. 7, the small container 200 is formed with a smaller “length”, “width”, and “height” than the large container 100. That is, the small container 200 has a bottom 201 formed in a rectangular shape and side walls 202 rising from four sides of the bottom 201, for example, in the same manner as the large container 100. Further, the small container 200 has legs 204 protruding downward from four corners 201a on the bottom 201. Furthermore, the small container 200 is formed in a box shape with an opening 206 provided at the upper end portion 205.

[0046] Place the storage case lid 10 above the upper end portion 205 of the small container 200. The lid body 12 is placed on the upper end portion 205 of the small container 200. Further, the four second vertical walls 15 contact or are close to the outer periphery 205a of the upper end portion 205. Thereby, the four second vertical walls 15 can suppress the rattling of the storage case lid 10 with respect to the upper end portion 205 of the small container 200. In this state, the opening 206 of the upper end portion 205 in the small container 200 can be covered with the storage case lid 10. Further, another small container (not shown) may be stacked on the storage case lid 10 disposed on the upper end portion 205 of the small container 200.

[0047] Next, an example of using the storage case lid 10 for another large container 150 will be described with reference to FIG. 8. FIG. 8 is a cross-sectional view for explaining an example of using the storage case lid of the embodiment for another large container. In FIG. 8, the large container 150 will be briefly described. As shown in FIG. 8, place the storage case lid 10 above the upper end portion 155 of the large container (storage case) 150. The lower sides 41d (see FIG. 4) of the plurality of first reinforcing ribs 41 and the lower sides 42a of the plurality of second reinforcing ribs 42 are placed on the upper end portion 155 of the large container 150. Further, the four regulating portions 32 in the first vertical wall 14 contact or are close to the outer periphery 155a of the upper end portion 205.

[0048] Thereby, the rattling of the storage case lid 10 with respect to the upper end portion 155 of the large container 150 and the detachment from the upper end portion 155 can be suppressed by the four regulating portions 32. In this state, the opening of the upper end portion 155 in the large container 150 can be covered with the storage case lid 10, and the storage case lid 10 can be stably held on the upper end portion 155 of the large container 150. Yes.

[0049] Next, an example of using the storage case lid 10 for another small container 250 will be described with reference to FIG. 9. FIG. 9 is a cross-sectional view for explaining an example of using the storage case lid of the embodiment for another small container. In FIG. 9, the small container 250 will be briefly described. As shown in FIG. 9, the storage case lid 10 is disposed above the upper end portion 255 of the small container (storage case) 250. The lower sides 41d of the plurality of first reinforcing ribs 41 (see FIG. 4) and the lower sides 42a of the plurality of second reinforcing ribs 42 are placed on the upper end portion 255 of the small container 250. Further, the four second vertical walls 15 contact or are close to the inner circumference 255a of the upper end portion 255.

[0050] Thereby, the four second vertical walls 15 can suppress the rattling of the storage case lid 10 with respect to the upper end portion 255 of the small container 250 and the detachment from the upper end portion 255. In this state, the opening of the upper end portion 255 in the small container 250 can be covered with the storage case lid 10, and the storage case lid 10 can be stably held on the upper end portion 255 of the small container 250.

[0051] As described above, according to the storage case lid 10 of the embodiment, as shown in FIG. 6, the first vertical wall 14 projects downward from the outer wall 27 of the raised portion 13. Therefore, when the storage case lid 10 is used for the large container 100, the upper end portion 105 of the large container 100 can be disposed inside with respect to the first vertical wall 14. Thereby, the detachment of the storage case lid 10 from the upper end portion 105 of the large container 100 can be prevented by the first vertical wall 14 (particularly, the restricting portion 32), and the storage case lid 10 can be stably held on the upper end portion 105 of the large container 100.

[0052] Also, as shown in FIG. 8, when the storage case lid 10 is used for the large container 150, the upper end portion 155 of the large container 150 can be disposed inside with respect to the first vertical wall 14. Thereby, the detachment of the storage case lid 10 from the upper end portion 155 of the large container 150 can be prevented by the first vertical wall 14 (particularly, the restricting portion 32), and the storage case lid 10 can be stably held on the upper end portion 155 of the large container 150.

[0053] Furthermore, as shown in FIG. 7, the second vertical wall 15 is projected downward from a position 12b away from the center side of the lid body 12 with respect to the inner wall 25 of the raised portion 13. Therefore, when the storage case lid 10 is used for the small container 200, the upper end portion 205 of the small container 200 can be arranged inside with respect to the second vertical wall 15. Thereby, the second vertical wall 15 can prevent the storage case lid 10 from coming off from the upper end portion 205 of the small container 200, and the storage case lid 10 can be stably held on the upper end portion 205 of the small container 200.

[0054] In addition, as shown in FIG. 9, when the storage case lid 10 is used for the small container 250, the upper end portion 255 of the small container 250 can be arranged outside with respect to the second vertical wall 15. Also in the case of the small container 250, the second vertical wall 15 can prevent the storage case lid 10 from coming off from the upper end portion 205 of the small container 200, and the storage case lid 10 can be stably held on the upper end portion 205 of the small container 200.

[0055] In this way, in the storage case lid 10, the first vertical wall 14 is projected downward and the second vertical wall 15 is projected downward. Therefore, the storage case lid 10 can be made to correspond to containers of different sizes such as the large containers 100, 150 and the small containers 200, 250. In other words, the storage case lid 10 can correspond to containers of various sizes by changing the contact (contact) portions with the large containers 100, 150 and the small containers 200, 250, and can be prevented from moving more than necessary with respect to the container.

[0056] Furthermore, as shown in FIG. 6, another large container 120 can be placed on the lid body 12 of the storage case lid 10. Here, legs 122 project downward from the bottom 121 of the other large container 120. Therefore, in a state where another large container 120 is stacked on the raised portion 13, the legs 122 can be arranged inside with respect to the inner wall 25 of the raised portion 13. Thereby, it is possible to prevent the other large container 120 from coming off from the storage case lid 10, and the other large container 120 can be stably held on the storage case lid 10.

[0057] Further, as shown in FIGS. 2 and 7, the second standing wall 15 is disposed inside the corner body 12a of the lid body 12 and is provided along the corner body 12a. Therefore, the second standing wall 15 is formed in a curved shape in plan view. Thereby, the rigidity (strength) of the second standing wall 15 can be ensured. Therefore, the storage case lid 10 can be held more stably at the upper end portion 205 of the small container 200.

[0058] Also, by providing the second standing wall 15 on the corner body 12a of the lid body 12, the weight of the storage case lid 10 can be reduced as compared with, for example, the case where the second standing wall 15 is provided on the entire circumference of the lid body 12. Furthermore, the raw materials used for manufacturing the storage case lid 10 can be reduced.

[0059] Furthermore, as shown in FIGS. 2, 6, and 8, the restricting portion 32 of the first standing wall 14 is recessed in a stepped manner toward the lid body 12 side. Therefore, the restricting portion 32 can be brought into contact with or close to the upper end portion 105 (specifically, the outer circumference 105a) of the large container 100. Thereby, the rattling of the storage case lid 10 with respect to the upper end portion 105 of the large container 100 can be suppressed by the restricting portion 32. Similarly, the restricting portion 32 can be brought into contact with or close to the upper end portion 155 (specifically, the outer circumference 155a) of the large container 150. Thereby, the rattling of the storage case lid 10 with respect to the upper end portion 155 of the large container 150 can be suppressed by the restricting portion 32. Also, by providing the restricting portion 32 in the first standing wall 14 in a stepped recessed manner, the rigidity (strength) of the second standing wall 15 can be ensured. Thereby, the storage case lid 10 can be held more stably at the upper end portion 105 of the large container 100 and at the upper end portion 155 of the large container 150.

[0060] In addition, as shown in FIGS. 1 and 8, a pair of first groove portions 51, a pair of second groove portions 52, and a pair of third groove portions 53 are provided in the raised portion 13. For example, a binding belt 60 wound around the outer periphery of the large containers 100 and 150 is passed through the pair of first groove portions 51, the pair of second groove portions 52, and the pair of third groove portions 53. Thus, the binding belt 60 can be held at a predetermined position of the storage case lid 10. Thereby, the storage case lid 10 can be easily fixed to the upper end portion 105 of the large container 100 or the upper end portion 155 of the large container 150 with the binding belt 60. Similarly to the large containers 100 and 150, the storage case lid 10 can be easily fixed to the upper end portion 205 (both, see FIG. 7) of the small container 200 or the upper end portion 255 (both, see FIG. 9) of the small container 250 with the binding belt 60.

[0061] Note that the technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0062] In addition, within the scope not departing from the spirit of the present invention, it is possible to appropriately replace the components in the above-described embodiment with well-known components, and the above-described modified examples may be appropriately combined.
