[0003] [Patent Document 1] JP 2014-003949 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the cooler box of Patent Document 1, the rigidity of the base part is the same as that of the contact part. Therefore, if the amount of protrusion of the contact part is increased to enlarge the area where the contact part contacts the box body, a finger may get caught on the contact part and the base part may come off the groove part. Also, if the depth of the groove part is made shallow to increase the amount of protrusion of the contact part, the base part becomes more likely to come off the groove part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] 1 and 2, a cooler box 1 according to an embodiment of the present invention includes a box body 3, a cover member 5, and a sealing member 7. In the following, the up-down direction is defined with the cooler box 1 in a state where it is placed on the ground. In other words, the up-down direction is the direction in which gravity acts on the cooler box 1.

[0026] As shown in Fig. 1, the box body 3 has an opening 14 that opens upward. That is, the box body 3 is formed in a box shape that opens upward. The box body 3 has an outer case 11 shown in Fig. 1 and an inner case 13 shown in Fig. 2. The inner case 13 is disposed inside the outer case 11 and attached to the outer case 11.

[0027] As shown in Fig. 3, the inner surface of the inner case 13 forms an opening 14. The inner case 13 has a protrusion 13a. The protrusion 13a protrudes from an upper surface 13b of the inner case 13. In detail, the protrusion 13a protrudes in an arc shape from the upper surface 13b of the inner case 13. The protrusion 13a extends in a rectangular shape so as to surround the opening 14 of the inner case 13.

[0028] 1, the cover member 5 is formed in a substantially rectangular shape. The cover member 5 is disposed opposite the box body 3. In detail, the cover member 5 is disposed opposite the box body 3 so as to cover the opening 14 of the box body 3.

[0029] The cover member 5 is configured to be attachable to and detachable from the box body 3 by operating a pair of operating members 9. In detail, the cover member 5 is configured to be attachable to and detachable from the outer case 11 by operating the pair of operating members 9.

[0030] As shown in FIG. 2, the lid member 5 has an outer lid 15 and an inner lid 17. The inner lid 17 is disposed inside the outer lid 15 and attached to the outer lid 15. The inner lid 17 is disposed facing the inner case 13. The inner lid 17 has a groove 17a. The groove 17a is provided on a surface facing the inner case 13, for example, a lower surface 17b of the inner lid 17. The groove 17a is recessed from the lower surface 17b of the inner lid 17 and extends in a rectangular shape. When the lid member 5 is attached to the box body 3, the groove 17a is disposed facing the protrusion 13a shown in FIG. 3.

[0031] As shown in Fig. 2, the seal member 7 is disposed in the groove portion 17a. As shown in Fig. 4, the seal member 7 has a base portion 19, a contact portion 21, and a connecting portion 23. As shown in Figs. 5A and 5B, the base portion 19 is fitted into the groove portion 17a. Specifically, as shown in Fig. 4, the base portion 19 is formed as a solid body. As shown in Figs. 5A and 5B, the base portion 19 is press-fitted into the groove portion 17a.

[0032] As shown in Fig. 4, the contact portion 21 is provided on the base portion 19. In this embodiment, the contact portion 21 is integrally formed with the base portion 19. The contact portion 21 has a hollow portion therein. As shown in Fig. 5B, the contact portion 21 comes into contact with the box main body 3.

[0033] 5B, when the base portion 19 is press-fitted into the groove portion 17a, the contact portion 21 contacts the box main body 3. More specifically, when the base portion 19 is press-fitted into the groove portion 17a, the contact portion 21 contacts the protrusion portion 13a. More specifically, when the base portion 19 is press-fitted into the groove portion 17a, the contact portion 21 contacts the upper surface 13b of the inner case 13 and the protrusion portion 13a.

[0034] As shown in FIG. 4, the connecting portion 23 connects the contact portion 21 and the base portion 19. The connecting portion 23 is formed integrally with the contact portion 21 and the base portion 19. As shown in FIG. 5A, the connecting portion 23 is partially fitted into the groove portion 17a. Specifically, as shown in FIG. 4, a part of the connecting portion 23 has a hollow portion therein. That is, a hollow portion is formed inside the contact portion 21 and the connecting portion 23. As shown in FIG. 5A, the connecting portion 23 is partially press-fitted into the groove portion 17a.

[0035] 4, the connecting portion 23 has a mark portion 23a. The mark portion 23a is used to determine whether the fitting depth of the seal member 7 with respect to the groove portion 17a is appropriate.

[0036] 4, the mark portion 23a includes a pair of mark portions 23a. The pair of mark portions 23a is provided on the surface 23b of the connecting portion 23. The pair of mark portions 23a protrude from the surface 23b of the connecting portion 23. The pair of mark portions 23a may extend continuously along the direction in which the seal member 7 extends, or may be disposed at a predetermined interval in the direction in which the seal member 7 extends.

[0037] 5B, when the seal member 7 is fitted into the groove portion 17a, the pair of mark portions 23a are disposed opposite to a pair of corner portions 18 formed by the wall surface of the groove portion 17a and the lower surface 17b of the inner lid 17. By disposing the pair of mark portions 23a in this manner, the seal member 7 can be appropriately disposed with respect to the groove portion 17a.

[0038] In the above-described cooler box 1, the rigidity of the base portion 19 is higher than the rigidity of the contact portion 21. In particular, the rigidity of the base portion 19 is higher than the rigidity of the contact portion 21 and is higher than the rigidity of the connecting portion 23.

[0039] When the seal member 7 is disposed in the groove 17a, the ratio (BH / GH) of the contact height BH of the base portion 19 to the wall height GH of the groove 17a is preferably 0.4 or more and 1.0 or less. When the wall height GH varies, the wall height GH is evaluated as the minimum wall height of the groove 17a.

[0040] With the seal member 7 disposed in the groove 17a, the ratio (CH / GH) of the protruding height CH of the contact portion 21 to the wall height GH of the groove 17a is preferably greater than 0 and less than or equal to 1.0. If the wall height GH varies, the protruding height CH of the contact portion 21 is evaluated as the maximum protruding height.

[0041] In the above-described cooler box 1, the rigidity of the base portion 19 is higher than the rigidity of the contact portion 21, and the base portion 19 is press-fitted into the groove portion 17a of the lid member 5, and the contact portion 21 contacts the box body 3. This configuration can improve the holding force of the seal member with respect to the groove portion.

[0042] (Modification) The seal member 7 of the embodiment may be configured as the seal member 107 shown in Fig. 6. In this case, the base portion 119 has a first base portion 119a and a second base portion 119b. The first base portion 119a is formed integrally with the contact portion 21. In detail, the first base portion 119a is formed integrally with the contact portion 21 via the connecting portion 23.

[0043] In this modification, the first base portion 119a is integrally formed with the connecting portion 23, and the connecting portion 23 is integrally formed with the contact portion 21. The second base portion 119b is formed separately from the first base portion 119a. The second base portion 119b is attached to the first base portion 119a. The hardness of the second base portion 119b is higher than the hardness of the first base portion 119a.

[0044] In this configuration, the thickness of base portion 119 can be adjusted by second base portion 119b according to the depth of groove portion 17a. Also, by making the hardness of second base portion 119b higher than the hardness of first base portion 119a, the holding force of seal member 107 to groove portion 17a can be improved.

[0045] Second base portion 119b may be made of a resin material different from that of first base portion 119a and integrated with first base portion 119a by a technique such as two-color molding. Second base portion 119b made of a metal such as a stainless steel alloy may be attached to first base portion 119a by adhesive or double-sided tape. [Explanation of symbols]
