Description

The present invention relates to a storage container for storing stored items, which has a double structure of an outer container that maintains the outer shape and an inner container that is mounted inside the container and is in charge of heat insulation from the outside world.

Conventionally, there has been known a storage container in which an inner container having a certain degree of flexibility and high heat insulation is attached to the inside of an outer container having a relatively high rigidity to have a cold or heat insulating function. The one described in Patent Document 1 is also an example. In this type of double-structured storage container, the inner container is usually removable from the outer container. The same applies to the heat insulating container of Patent Document 1.

In the heat insulating container of the same document, the one indicated by "10" in FIG. 1 is the outer body (outer container), and the one indicated by "20" is the inner body (inner container). "30" is the lid of the interior body. Looking at the "exterior body 10" among them, "through ports 12" for handles are provided on the side wall portions on both short sides thereof. Along with this, a "convex portion 22" is provided outward on the side wall portion of the "interior body 20". Looking at FIG. 3 of the same document, a cross-sectional view of the "interior body 20" mounted inside the "exterior body 10" is drawn. In the state of this cross-sectional view, the "convex portion 22" has entered the "through port 12". As a result, the "interior body 20" is prevented from being detached from the "exterior body 10" by itself.

Japanese Unexamined Patent Publication No. 10-17031

However, the above-mentioned conventional storage container has the following problems. First, the "interior body 20" is unexpectedly easy to come off from the "exterior body 10". The cause lies in the positions of the "convex portion 22" and the "through port 12". That is, as is clear from FIG. 1 of Patent Document 1, the "convex portion 22" and the "through port 12" are located at the central portion in the width direction in the side wall portion where they are formed. This is the position where the side wall is most deformed when some external force is applied. For this reason, the "convex portion 22" and the "through port 12" are unexpectedly easily disengaged.

The "through port 12" also has a meaning as a handle when a person holds a heat insulating container. However, when a finger is inserted into the "through hole 12" for that purpose, the "convex portion 22" exists there. That is, the "convex portion 22" interferes with the function as a handle. Further, in many cases, the "interior body 20" is made of a highly flexible material such as a foaming material. Therefore, the "convex portion 22" may be damaged or deformed due to a collision with a finger inserted into the "through port 12". In this case, the hooking function between the "convex portion 22" and the "through port 12" is reduced, and the "interior body 20" is more likely to come off from the "exterior body 10".

The present invention has been made to solve the problems of the above-mentioned conventional techniques. That is, the problem is to provide a storage container in which the inner container does not easily come off from the outer container and the locking shape for that purpose does not interfere with other functions of the storage container.

The storage container according to one aspect of the present invention is a storage container composed of an outer container made of a non-foamed resin material and an inner container made of a foamed resin material mounted inside the outer container. also be of a shape having a side wall portion provided on the same side with respect to the respective sides and polygonal-shaped bottom portion, with the engaging portion is provided on the outer surface of the side wall of the inner container A locked portion is provided on the inner surface side of the side wall portion of the outer container, and the locked portion and the locked portion are caught in the state where the inner container is attached to the outer container. It prevents the inner container from coming off by itself, and is provided at a position within 30% from one end of the formed side wall portion with respect to the total width in the horizontal direction.

In the storage container in the above aspect, the locked portion and the locked portion are caught in the mounted state in which the inner container is mounted on the outer container. As a result, the inner container cannot be removed from the outer container by itself. The position where the locking portion and the locked portion are formed is a position near the end portion of the formed side wall portion, which is deviated from the central portion in the width direction. Therefore, even if an unintended external force is applied to the side wall portion of the inner container, the position where the locking portion and the locked portion are formed does not deform so much. For this reason, it is difficult to release the hook between the locked portion and the locked portion. In addition, the locking portion does not interfere with the function of the handle hole or the like, which is usually formed in the central portion in the width direction of the side wall portion. The "multi-sided shape" of the bottom surface of the outer container and the inner container is often a rectangle, but is not limited to this and may be any polygon. Also, even if the corners are rounded, it does not prevent it from being a polyhedron.

Further, in the storage container in the above aspect, it is desirable that a groove in the vertical direction is formed in the side wall portion of the inner container, and the locking portion is formed at a position within 10 mm in the horizontal direction from the outer edge of the groove. As a result, the portion of the side wall portion of the inner container where the locking portion is formed is likely to be deformed when the side wall portion is intentionally deformed for mounting or removing the inner container. Therefore, it is easy to attach or detach.

Or in the container above Symbol embodiment, easily deformable portion on the side wall of the inner container is formed, easily deformable portion, the vertical direction of the grooves and the region between the two formed in the side wall, the side wall portion the formed thin recess regions, areas that are raised foaming rate of the material resin is from locations other than the easily deformable portion of the side wall portion is either, locking unit is in the range of easily deformable portions It is desirable that it is formed. Since the locking portion is formed within the range of the easily deformed portion in this way, the side wall portion is easily deformed during the mounting or dismounting operation, and the operation is easy.

Easily deformable portion more in storage container state like that provided is a plurality of engaging portions on the outer surface of definitive within the easy deformation portion is formed, on the inner surface side of the side wall of the external container, the outer It is desirable that a plurality of locked portions are formed at positions corresponding to the plurality of locking portions with the inner container attached to the container. By providing a plurality of locked portions within the range of one easily deformed portion in this way, it is difficult for the inner container to come off by itself from the outer container even if the easily deformed portion is provided. ..

In the storage container of any of the above aspects, the inner container also has a partition-shaped portion continuously provided from the inner surface of the side wall portion, which partitions a part of the storage space partitioned by the bottom surface portion and each side wall portion. A positioning convex portion provided on the outer surface of the side wall portion within a range corresponding to the back surface of the position where the partition shape portion is formed, which contacts the inner surface of the side wall portion of the outer container when the inner container is attached to the outer container. It is desirable that and is formed. By reinforcing the position of the positioning convex portion by using the partition shape portion in this way, the positioning effect of the positioning convex portion on the outer container of the inner container becomes more reliable.

In the storage container of the above aspect provided with the partition shape portion and the positioning convex portion, the locking portion is further located on the outer surface of the side wall portion of the inner container, rather than the range in which the partition shape portion is formed on the back surface. It is desirable that the container is provided at a position closer to the center in the width direction. As a result, the partition shape portion does not interfere with the intentional deformation of the side wall portion of the inner container during the mounting or dismounting operation. In the storage container of any of the above aspects, it is also desirable that the locking portion is provided at a position within the upper half of the vertical dimension of the side wall portion of the inner container. As a result, there is less intentional deformation during the mounting or dismounting operation.

According to this configuration, a storage container is provided in which the inner container does not easily come off from the outer container, and the locking shape for that purpose does not interfere with other functions of the storage container.

Hereinafter, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings. This embodiment embodies the present invention as the storage container 1 shown in FIG. The storage container 1 of FIG. 1 is composed of an outer container 2, an inner container 3, and a lid 4. The outer container 2 is a part that has the outer shape of the storage container 1 and has the necessary strength. The inner container 3 is a part that actually stores the stored items in the storage container 1. The main functions of the inner container 3 are heat insulating properties and shock absorbing properties. The lid 4 is a part that closes the opening of the inner container 3.

The materials of the outer container 2, the inner container 3, and the lid 4 are all synthetic resins. However, the type of material resin is different between the outer container 2 and the inner container 3. Comparing the material resin of the outer container 2 and the material resin of the inner container 3, the latter has higher flexibility and higher heat insulation. The type of resin itself is not particularly limited, but by forming the outer container 2 with a non-foaming resin (for example, polypropylene, etc.) and the inner container 3 with a foamed resin (for example, foamed polypropylene, foamed polyethylene, foamed polystyrene, etc.), the above Can be achieved. The material of the lid 4 may be the same as that of the inner container 3.

Both the outer container 2 and the inner container 3 have a box shape with an upper opening as a general outline shape as a whole. That is, the outer container 2 has a rectangular bottom surface portion 21, a long side side wall portion 23 provided on the upper side with respect to both long sides thereof, and a short side side wall portion provided on the upper side with respect to both short sides. It has 24 and. A large number of holes 25 are formed in the bottom surface portion 21. A large number of holes 26 are also formed in each long side side wall portion 23. A handle hole 27 is formed in each short side side wall portion 24. The handle hole 27 is located at the center of the short side side wall portion 24 in the width direction (the longitudinal direction of the short side side wall portion 24 when viewed from above).

The inner container 3 also has a rectangular bottom surface portion 31, a long side side wall portion 33 provided on the upper side with respect to both long sides thereof, and a short side side wall portion 34 provided on the upper side with respect to both short sides. And have. A partition-shaped portion 35 is provided inside the inner container 3. The partition shape portion 35 is continuously provided from the inner surfaces of the long side side wall portion 33 and the short side side wall portion 34. The partition shape portion 35 partitions a part of the storage space inside the inner container 3 and serves as a place to attach the cooling agent 5 shown in FIG. A convex locking portion 36 and a positioning convex portion 37 are provided on the outer surface of the long side side wall portion 33 of the inner container 3. In FIG. 1, only the locking portion 36 of the long side side wall portion 33 on the front side is visible, but the locking portion 36 is also formed on the outer surface of the long side side wall portion 33 on the back side. The positioning convex portion 37 is also provided on the outer surface of the short side side wall portion 34 of the inner container 3. The inner container 3 is not provided with a hole as provided in the outer container 2.

FIG. 3 shows a perspective view of the outer container 2, the inner container 3, and the lid 4 in a state of being turned upside down. The lid 4 is a rectangular plate-shaped member that has almost the same overall shape as the bottom surface portion 21 and the bottom surface portion 31.

FIG. 4 shows a perspective view of the outer container 2 with the inner container 3 attached. In the storage container 1 in the state shown in FIG. 4, the lid 4 is not attached. On the other hand, in the storage container 1 of FIG. 4, the ice pack 5 shown in FIG. 2 is attached. The ice pack 5 in FIG. 2 is held in the space between the short side side wall portion 34 and the partition shape portion 35 in the inner container 3.

Further, in FIG. 4, the locking portion 36 of the inner container 3 projects to the outside through the hole 26 of the outer container 2. That is, the convex locking portion 36 is in a state of being caught in the hole 26 which is a through hole from the inner surface side. That is, the hole 26 functions as a locked portion on which the locking portion 36 is hooked. The state of being caught between the locking portion 36 and the hole 26 is shown in the cross-sectional view of FIG. As a result, in the storage container 1 of FIG. 4, the inner container 3 cannot be removed from the outer container 2 by itself. Although a large number of holes 26 are provided in FIG. 4 and the like, the locking portion 36 is hooked at a position facing the locking portion 36 when the outer container 2 and the inner container 3 are mounted. There is. However, since the inner container 3 is flexible as described above, the inner container 3 can be removed from the outer container 2 by intentionally pushing the locking portion 36 from the outside to release the hook with the hole 26. Can be done.

The inner container 3 will be further described with reference to the plan view of FIG. In FIG. 6, the total length of the inner container 3 in the long side direction is indicated by L1. This L1 is the total width of the long side side wall portion 33. L2 in FIG. 6 indicates a range corresponding to 30% of the total width L1 from one end (right end in FIG. 6) of the long side wall portion 33. The locking portion 36 of the inner container 3 is provided within the range of this region L2. That is, the locking portion 36 is formed at a position off the center of the long side side wall portion 33 in the width direction. As a result, in the storage container 1 of the present embodiment, the inner container 3 is less likely to come off from the outer container 2 than the conventional one. Even if some kind of stress is applied to the long side side wall 33, it is greatly deformed because it is the central part in the width direction of the long side side wall 33, and the locking part 36 is at a position deviated from that. be. Therefore, even if some unintended external force is applied to the long side side wall portion 33, the deformation of the portion where the locking portion 36 is located is small, and it is difficult to release the hook between the locking portion 36 and the hole 26. There is no such thing.

Further, as shown in FIGS. 1, 3 and 6, a vertical groove 38 is formed at a position between two locking portions 36 on the outer surface of the long side side wall portion 33 of the inner container 3. There is. Therefore, the long side side wall portion 33 is more easily deformed in the groove 38 and the portion around it as compared with other portions. That is, the position near the locking portion 36 in the long side side wall portion 33 is a easily deformed portion that is more easily deformed than other positions. This easily deformed portion includes the groove 38 itself, and further includes an adjacent region (a region within 10 mm in the horizontal direction from the outer edge of the groove 38). Therefore, the operation of mounting the inner container 3 on the outer container 2 can be easily performed by forming the groove 38. The same applies when the inner container 3 is intentionally removed from the outer container 2. Even if an unintended external force is applied to the long side side wall portion 33 in the mounted state, the inner container 3 is not likely to come off due to the groove 38 unless the external force specifically targets the position near the locking portion 36. ..

Further, as is clear from FIG. 6, the locking portion 36 is in the width direction of the long side side wall portion 33 (direction of arrow L1) rather than the range in which the partition shape portion 35 is continuous with the inner surface of the long side side wall portion 33. It is located on the outer surface at a position closer to the center. That is, when the inner container 3 is viewed from above, the partition shape portion 35 is not formed at the position on the back surface of the position where the locking portion 36 is provided. Therefore, when the inner container 3 is attached or detached, the partition-shaped portion 35 does not hinder the deformation of the long side side wall portion 33. In this respect as well, it can be said that the storage container 1 of the present embodiment can easily attach and detach the inner container 3.

Further, as can be seen from FIG. 1, the locking portion 36 is provided at a position within the range of the upper half in the vertical dimension of the long side side wall portion 33. This also makes it easy to attach and detach the inner container 3. This is because, at the time of attachment, it is necessary to deform the long side side wall portion 33 so as to push the locking portion 36 inward, but the time required for the deformation is short. Further, at the time of removal, it is also necessary to deform the locking portion 36 by pushing it inward, but this is because the locking portion 36 escapes from the outer container 2 at an early stage and the deformation is eliminated.

Further, as also shown in FIGS. 1, 3 and 6, the positioning convex portion 37 is arranged at a position within a range in which the partition shape portion 35 is continuous with the long side side wall portion 33 or the short side side wall portion 34. Has been done. That is, when the inner container 3 is viewed from above, the partition-shaped portion 35 is formed at the position on the back surface of the position where the positioning convex portion 37 is provided. This has the following effects.

In the first place, the positioning convex portion 37 stabilizes the position of the inner container 3 in the horizontal plane in the mounted state of FIG. That is, when the storage container 1 in the mounted state is viewed from above, it is as shown in FIG. In FIG. 7, the inner surface of the outer container 2 and the outer surface of the inner container 3 are firmly in close contact with each other only at the positioning convex portion 37. This situation is shown in the cross-sectional view of FIG. The positioning convex portion 37 in the states of FIGS. 7 and 8 is pushed by the inner surface of the outer container 2 and is in a slightly compressed state. As a result, the position of the inner container 3 in the horizontal plane with respect to the outer container 2 is stable. In particular, even if the storage container 1 is a combination in which the fitting is loose due to individual differences within the dimensional tolerances of the outer container 2 and the inner container 3, the position of the inner container 3 is stable due to the effect of the positioning protrusion 37. ..

Here, due to the positional relationship between the positioning convex portion 37 and the partition shape portion 35 described above, the backward movement of the positioning convex portion 37 by the inner surface of the outer container 2 in the mounted state, that is, the inward movement is suppressed. As a result, the positioning effect of the positioning convex portion 37 is more reliable. Even in the state shown in FIG. 7, the lid 4 is not attached as in FIG. Further, in the state of FIG. 7, the ice pack 5 is not attached. On the other hand, FIG. 8 shows a state in which the lid 4 and the ice pack 5 are attached to the inner container 3. As can be seen from FIG. 8, the presence of the lid 4 also contributes to suppressing the retreat of the positioning convex portion 37 and further ensuring the positioning effect.

Further, as also shown in FIGS. 1, 3 and 6, the range adjacent to the positioning convex portion 37 on the outer surface of the long side side wall portion 33 and the short side side wall portion 34 is the concave portion 39. The recess 39 is continuously formed from the upper end to the lower end. Since the concave portion 39 is formed, it is easy to insert the inner container 3 into the outer container 2 while compressing the positioning convex portion 37. This is because the influence of the deformation of the positioning convex portion 37 due to compression does not reach much outside the concave portion 39 of the long side side wall portion 33 and the short side side wall portion 34.

The storage container 1 of this embodiment can be stacked in multiple stages. FIG. 9 shows a state in which the storage containers 1 are stacked in three stages. In FIG. 9, the locking portion 36 is seen through the hole 26 in any of the three-tiered outer containers 2. From this, it can be seen that each storage container 1 is in a state in which the inner container 3 is attached to the outer container 2. Further, although it is not clear in the drawing only for the uppermost container, the lid 4 is attached to the inner container 3 in each storage container 1. Regarding the ice pack 5, there is no difference in the external view of FIG. 9 whether or not it is attached.

Subsequently, a modified example of the inner container 3 in the storage container 1 of the present embodiment will be described. The first modification (FIGS. 10 and 11) and the second modification (FIGS. 12 and 13) will be described here. It will be explained in order.

First, a perspective view of the inner container 6 according to the first modification is shown in FIG. 10, and a plan view is shown in FIG. 11, respectively. The difference between the inner container 6 of FIGS. 10 and 11 from the above-mentioned inner container 3 is the arrangement of the locking portion 36 and the groove 38. That is, in the above-mentioned interior container 3, two locking portions 36 are formed within a range closer to one end in the width direction of each long side side wall portion 33, whereas in the interior container 6 according to this modification, the interior container 3 has two locking portions 36. , One locking portion 36 is formed in the range near both ends in the width direction of each long side side wall portion 33. The total number of locking portions 36 is the same for both the inner container 3 and the inner container 6.

On the other hand, regarding the groove 38, in the above-mentioned inner container 3, one groove 38 is formed between two adjacent locking portions 36. On the other hand, in the inner container 6 of the present modification, one groove 38 is formed on both sides of each locking portion 36. That is, in terms of the total number of grooves 38, the number of the interior container 3 is 2, whereas the number of the interior container 6 is 8. The easily deformed portion in this case includes at least two grooves 38 and a region between them. Therefore, even if the relationship between the locking portion 36 and the groove 38 is the same as that of the inner container 6 of the present modification, the outer container 2 and the inner container 6 are surely connected as in the case of the above-mentioned inner container 3. It can be prevented from coming off and easy to install. Regarding the other points, there is no particular difference between the inner container 3 and the inner container 6.

Next, a perspective view of the inner container 7 according to the second modification is shown in FIG. 12, and a plan view is shown in FIG. 13, respectively. The difference between the inner container 7 of FIGS. 12 and 13 from the above-mentioned inner container 3 is that the recess 40 is formed in place of the groove 38. The groove 38 is formed on the outer surface of the long side side wall portion 33, while the recess 40 is formed on the inner surface. Within the range where the recess 40 is formed, the long side side wall portion 33 is thinner than the other portions. The easily deformed portion in this case includes at least the range in which the recess 40 is formed. Further, an adjacent region (a region within 10 mm in the horizontal direction from the outer edge of the recess 40) is also included. The locking portions 36 in the inner container 7 of the present modification are all located within a range corresponding to the back surface of the range in which the recess 40 is formed. Even with such a configuration, as in the case of the inner containers 3 and 6 described above, it is possible to surely prevent the outer container 2 and the inner container 7 from coming off and to facilitate the mounting operation. Regarding the other points, there is no particular difference between the inner container 3 and the inner container 7.

As described in detail above, according to the present embodiment, in the storage container 1 in which the inner container (3, 6, 7) having higher flexibility and higher heat insulation is attached to the outer container 2. The locking portion between the hole 26 (locked portion) of the outer container 2 and the locking portion 36 of the inner container (3, 6, 7) is removed from the vicinity of the center in the width direction of the long side wall portions 23, 33. It is placed near the edge. Therefore, even when an unintended external force is applied to the inner container (3, 6, 7), the amount of deformation of the locked portion of the inner container (3, 6, 7) is small. Therefore, it is unlikely that the inner container 3 will come off from the outer container 2 by itself.

Further, the locking portion 36 does not enter the handle hole 27 located at the center of the short side side wall portion 24 of the outer container 2 in the width direction even in the mounted state. Therefore, the operation of inserting the fingertip into the handle hole 27 and lifting the storage container 1 is not hindered by the locking portion 36. Moreover, the locking portion 36 is not damaged by the operation.

Further, the portion of the inner container (3, 6, 7) where the locking portion 36 is formed is easily deformed by the groove 38 or the recess 40. Therefore, the mounting operation and the removing operation can be easily performed. Further, the inner container (3, 6, 7) is provided with a positioning convex portion 37 in addition to the locking portion 36, and is arranged at a position related to the front and back when viewed from above with respect to the partition shape portion 35 on the inner surface side. Has been done. Therefore, the positioning effect of the inner container (3, 6, 7) by the positioning convex portion 37 is certain. On the other hand, since the locking portion 36 is closer to the center than the partition shape portion 35, the partition shape portion 35 does not interfere with the mounting operation and the removing operation. Further, since the locking portion 36 is located at a position closer to the upper and lower side walls of the long side side wall portion 33, this also facilitates the mounting operation and the removing operation.

It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Therefore, as a matter of course, the present invention can be improved and modified in various ways without departing from the gist of the present invention. For example, in this embodiment, the locked portion, which is the shape of the outer container 2 for being hooked with the locking portion 36 in the mounted state, is a hole 26 which is a through hole. However, it is not essential that the locked portion is a through hole. Instead of the hole 26 which is a through hole, the portion may be a bottomed hole whose inner surface side is recessed. This is because even in this case, the locking portion 36 can enter the bottomed hole from the inner surface side and be caught in the mounted state.

Further, the relationship between the locking portion 36 and the locked portion may be reversed. That is, the locked portion is the inner surface-shaped convex portion of the long side side wall portion 23 of the outer container 2, and the locking portion 36 is the through hole or the outer surface side of the long side side wall portion 33 of the inner container (3, 6, 7). It may be a dented bottomed hole. Further, the locking portion 36 and the locked portion may be provided on the short side side wall portions 24, 34 instead of being provided on the long side side wall portions 23, 33. Alternatively, the locking portion 36 and the locked portion may be provided on both the long side side wall portions 23, 33 and the short side side wall portions 24, 34.

Further, in this embodiment, as is clear from FIG. 1 and the like, the long side side wall portion 23 is formed with the same shape as a large number of holes 26 in addition to the one that engages with the locking portion 36. Of course, this is not essential either, and a hole that does not engage with the locking portion 36 may not be formed. Alternatively, the shape may be different. Further, regarding the easily deformed portion, the arrangement of the groove 38 or the recess 40 is not limited to that shown in the figure. A groove 38 may be provided on the inner surface of the long side side wall portion 33, or a recess 40 may be provided on the outer surface. Both the groove 38 and the recess 40 may be provided. Alternatively, when the material resin of the inner container (3, 6, 7) is a foamed resin, the foaming rate may be increased only in the vicinity of the locking portion 36 as compared with the others, and this may be used as an easily deformed portion.

Further, the specific arrangement of the partition shape portion 35 is also arbitrary. In the example of the present embodiment, the ice pack 5 is brought close to the center of both short side wall portions 34 in the width direction and held one by one, but the present invention is not limited to this. The ice pack 5 may be held one by one toward the widthwise ends of both short side side wall portions 34, or one by one toward the widthwise center or end of both long side side wall portions 23. It may be the one that holds. The number of ice packs 5 held in the inner container (3, 6, 7) as a whole is not limited to two. It may be 1 or 4. Further, the positioning convex portion 37 does not necessarily have to be in a compressed state at the time of mounting. Also, the lid 4 is not absolutely necessary. For example, in the stacked state of FIG. 9, only the uppermost storage container 1 may have a lid 4, and the other storage containers 1 may have no lid 4.
