  The lid body of the heat insulating container of Patent Document 1 includes an outer lid member, an inner lid member, and a heat insulating member disposed between the outer lid member and the inner lid member, and the inner lid member is related to the outer lid member. By stopping, the heat insulating member is held in a state of being covered with the inner lid member. For this reason, when the lid is closed to the container body, the container body and the inner lid member made of a hard material come into contact with each other, so that the adhesion between the lid body and the container body is low. The pocket member is formed separately from the outer lid member and the inner lid member, and is locked and fixed to the inner lid member. That is, in the heat insulating container of Patent Document 1, since the inner lid member is an indispensable member for holding the heat insulating member and the pocket member, the number of members constituting the lid body increases, Since the weight of the lid increases, there is a drawback that it is difficult to perform the opening and closing operation.

  Moreover, since the outer cover member, the inner cover member, and the pocket member which comprise a cover body are separate bodies, since the heat insulation container of patent document 1 has a shaping | molding die, an installation expense becomes expensive and manufacturing cost increases. There are difficulties. In addition, as the number of molds increases, the number of setup operations related to mold replacement increases and the number of molding work steps increases. This is a factor that decreases manufacturing efficiency and increases manufacturing costs. Furthermore, since the number of constituent members is large, there is a difficulty in managing the members.

In the embodiment, a plurality of (three in the embodiment) protruding edge portions 78 are formed on the front edge 70a of the holding plate portion 70 so as to be separated from each other in the left and right direction. That is, projecting edge portions 78 are formed at the left end, the right end, and the left and right centers of the front edge 70 a of the holding plate portion 70. The left end and the right end protruding portion 78 is a portion formed by bending the holding plate portion 70 toward the second heat insulating member 42. Further, the left and right center protruding edge 78 is a portion formed so that the holding plate 70 swells toward the second heat insulating member 42.

  The protruding piece portion 76 and each protruding edge portion 78 provided on the holding plate portion 70 of the holding body 16 come into contact with the back side of the second heat insulating member 42 at the end portion facing the second heat insulating member 42. ing. That is, in the holding body 16, the protruding piece portion 76 and each protruding edge portion 78 abut on the second heat insulating member 42 in a state where the holding space 74 is defined between the holding plate portion 70 and the second heat insulating member 42. . Here, the projecting piece portion 76 and each projecting edge portion 78 may be brought into contact with the back side of the second heat insulating member 42 in a natural state where the return elastic force does not act on the holding plate portion 70, or the holding plate portion 70. It is also possible to contact the back side of the second heat insulating member 42 in a deformed state where the return elasticity is applied. In the configuration in which the protruding piece 76 and each protruding edge 78 are brought into contact with the back side of the second heat insulating member 42 in a state in which the return elastic force does not act on the article holding portion 64 of the holding body 16, the second heat insulating member 42 is the outer lid member 40. The holding body 16 can appropriately regulate the separation from the back side of the. Further, in the configuration in which the protruding piece 76 and each protruding edge 78 are in contact with the back side of the second heat insulating member 42 in a state where the return elastic force is applied to the article holding portion 64 of the holding body 16, the second heat insulating member is held by the holding body 16. 42 may be pressed against the back side of the outer lid member 40. Each protruding edge portion 78 can press the sheet-like article S inserted into the holding space 74 against the back side of the second heat insulating member 42.

(Assembling the lid)
The lid 14 configured as described above is assembled in the process shown in FIG. That is, the holding body 16 formed integrally with the outer lid member 40 in the unfolded state, the opening 54 of the second heat insulating member 42 formed in a separate process in the unfolded state. Then, the second heat insulating member 42 is inserted from the front side (see FIG. 9A). And the 2nd heat insulation member 42 is laid down to the holding plate part 70 side as the state which the opening 54 was located in the boundary part of the holding plate part 70 and the attachment plate part 66 (FIG.9 (b)). As a result, the mounting plate portion 66 of the holding body 16 is inserted into the through hole 54 of the second heat insulating member 42.

  Next, the holding body 16 in the unfolded state is folded back by the integral hinge 60, and the holding body 16 and the second heat insulating member 42 are integrally displaced (FIG. 9C). Here, in the middle of stacking the holding body 16 on the back side of the outer lid member 40, each second locking hook 46 is inserted into the corresponding mounting portion 68 and hooked (see FIG. 5 (b)), and each first The locking hooks 44 are inserted into the corresponding insertion ports 56 and hooked on the locking step portions 56a (see FIG. 5A).

  Thereby, the holding body 16 is held by the outer top plate portion 40a of the outer lid member 40 in the installed state by the second locking hooks 46 being locked to the mounting portions 68. On the other hand, the 2nd heat insulation member 42 is hold | maintained at the outer top plate part 40a of the outer cover member 40 because each 1st latching hook 44 is hooked on each latching step part 46a. The second heat insulating member 42 is also held from the back side by the article holding portion 70 of the holding body 16. Accordingly, the second heat insulating member 42 is sandwiched between the outer top plate portion 40a of the outer lid member 40 and the article holding portion 70 of the holding body 16 in the front and back direction, and is held without rattling when the lid 14 is opened and closed. .

  According to the heat insulating container 10 of the embodiment configured as described above, the holding body 16 connected to the outer edge of the outer edge plate portion 40b of the outer lid member 40 via the integral hinge 60 is connected to the outer edge of the outer lid member 40 from the outer edge. The back side of the second heat insulating member 42 passes through between the outer lid member 40 and the second heat insulating member 42, and through the through hole 54 formed in the second heat insulating member 42 corresponding to the inside of the opening of the inlet / outlet port 13. Therefore, the holding body 16 does not extend on the back side of the outer edge portion where the second contact surface 52 is formed in the second heat insulating member 42. That is, when the lid 14 is closed, the second contact surface 52 located at the outer edge of the second heat insulating member 42 is brought into contact with the first contact surface 30 located at the opening edge of the inlet / outlet 13 in the container body 12. When contacting, the holding body 16 does not get in the way, and the space between the lid body 14 and the container body 12 can be reliably sealed by the second heat insulating member 42 that directly contacts the first contact surface 30. . Further, since the second heat insulating member 42 can be appropriately deformed so that the second contact surface 52 comes into close contact with the first contact surface 30 when the cover body 14 is closed, the second heat insulating member 42 is disposed between the cover body 14 and the container body 12. Can be more reliably sealed. Therefore, the favorable heat insulation performance of the heat insulation container 10 is obtained, and the food B accommodated in the accommodation space 12a can be stored in a state where the temperature is maintained.

  Further, since the outer lid member 40 and the holding body 16 are integrally formed, the outer lid member 40 and the holding body 16 can be molded with the same mold, and the outer lid member 40 and the holding body are formed. There is no need to prepare a mold for each of the sixteen, and the number of molds can be reduced and the time required for mold changeover can be reduced, thereby reducing the manufacturing cost. The holding body 16 is connected to the outer edge of the outer lid member 40 via the integral hinge 60, and the holding body 16 is folded back by the integral hinge 60 from the unfolded state removed from the back side of the outer lid member 40. Therefore, the mold configuration can be simplified by molding in a developed state. Further, since the holding body 16 and the outer lid member 40 can be integrally formed with the holding body 16 in the unfolded state, the mold structure on the back side of the outer lid member 40 is not restricted by the holding body 16 and the second locking hook 46 Can be set to an optimum shape and position for holding the holding body 16, and the second locking hook 46 can be molded with a high degree of freedom. Similarly, since the mold structure on the back side of the outer lid member 40 is not restricted by the holding body 16, the first locking hook 44 can be set to an optimal shape and position for holding the second heat insulating member 42. In addition, since the holding body 16 and the outer lid member 40 can be integrally formed with the holding body 16 in an unfolded state, the mold structure of the holding body 16 is not restricted by the outer lid member 40, and the holding body 16 is attached to the article. It can be set to the optimal shape and position for holding. Furthermore, since the number of members constituting the heat insulating container 10 is reduced, there is an advantage that the member management becomes easy.

  The holding body 16 is connected to the outer edge of the outer lid member 40 by the integral hinge 60, and the second locking hook 46 and the attachment portion 68 are hooked, so that the holding body 16 is stacked on the back side of the outer lid member 40. The outer lid member 40 is stably held. When the sheet-like article S is put in and out of the holding space 74, even if the holding plate portion 70 of the holding body 16 is elastically deformed and a load is applied, the holding body 16 is against the outer lid member 40. Is maintained in the installed state.

  The second heat insulating member 42 is not separated from the back side of the outer lid member 40 because the first locking hook 44 and the locking step portion 56a formed on the outer top plate portion 40a of the outer lid member 40 are hooked. It is held by the outer lid member 40. In addition, since the second heat insulating member 42 is also held from the back side by the article holding portion 70 of the holding body 16, the second heat insulating member 42 is held more stably with respect to the outer lid member 40. Thereby, another member for holding the second heat insulating member 42 from the back side of the second heat insulating member 42 can be made unnecessary, and the weight of the lid 14 can be reduced.

The holding plate portion 70 of the article holding portion 64 in the holding body 16 is in contact with or separated from the back surface of the second heat insulating member 42 with the front edge 70a side being held on the outer top plate portion 40a of the outer lid member 40. Therefore, the sheet-like article S can be taken in and out of the holding space 74 easily and easily. And since the sheet-like article S accommodated in the holding space 74 can be elastically held by the article holding portion 70 of the holding body 16, the sheet-like article S is dropped from the holding space 74 when the lid body 14 is opened and closed. Can prevent. Further, since the sheet-like article S can be taken in and out of the holding space 74 from the front side and the right side of the lid body 14, the degree of freedom of putting and removing the sheet-like article S is high. Furthermore, since the holding space 74 is opened to the front and right sides, it is possible to hold the sheet-like article S having a size larger than that of the holding plate portion 70.
