Description

The present invention relates to containers and assembled containers.

BACKGROUND ART An assembled container including a plurality of containers of different sizes is known. When in use, it is possible to select a container of an appropriate size and store items therein, and when not in use, a small container can be stored inside a large container.

Patent Document 1 describes an invention related to a combination container consisting of containers of a plurality of sizes for accommodating food therein and storing it in a refrigerator or a freezer. The combination container consists of a large container, a medium container, and a small container. Each container has a container body and a lid, and the container body and lid are formed with a handle piece that projects outward. When not in use, the container body of the medium container is accommodated within the container body of the large container, and the container body of the small container is accommodated within the container body of the medium container. In this state, the upper edges of the container bodies of the medium and small containers do not protrude from the upper edges of the container bodies of the large container. Therefore, a stack of lids for a large container, a medium container, and a small container can be placed on top of the container body of the large container and stored with the handle pieces of the container body and the lid overlapped.

Japanese Patent Application Publication No. 5-317174

However, since the handle pieces of each container body and each lid are formed in a shape that projects horizontally outward from the side wall of the container body, the volume of the container body of a medium container is smaller than that of the container body of a large container. The volume of the small container and the volume of the container body of the small container have to be reduced. Therefore, container loss of the container body of medium containers and small containers becomes large. There is a need for containers and assembled containers that can suppress volume loss.

In order to solve the above problems, a container of the present invention includes a container main body having a side wall and a bottom wall and an opening formed at the upper edge of the side wall, and a lid that closes the opening. The side wall is provided with a handle portion extending upward from the upper edge and having a finger hole extending through the thickness direction, and the side edge of the lid body is provided with a handle portion having a shape concave downward. When a recess is formed and the lid closes the opening, the finger hole communicates with the recess.

According to the above configuration, the handle portion in which the finger hole is formed extends upward from the upper edge of the side wall of the container body. Therefore, compared to the case where the handle extends outward in the horizontal direction, the area occupied by the handle in the horizontal direction is reduced, and the outer dimension of the container in the horizontal direction can be reduced. As a result, when the container is housed inside a large outer container, the volume of the main body of the container can be ensured sufficiently with respect to the size of the outer container. Volume loss of the container can be suppressed.

In the above configuration, an inwardly recessed side wall is formed below the handle on the outer surface of the side wall, and the outer surface of the handle is flush with the outer surface of the side wall recess. It is preferable that

According to the above configuration, the outer surface of the handle portion is recessed inward from the outer surface of the side wall in the portion where the handle portion is not formed. Therefore, when the container is placed inside a larger outer container, even if there is almost no gap between the inner surface of the outer container and the outer surface of the container, you can insert your finger into the finger hole in the handle. Easy to do. The container can be easily taken in and out of the outer container while suppressing volume loss of the container.

In the above configuration, preferably, when the lid closes the opening, the lower end edge of the finger hole is located above the upper surface of the recess.
According to the above configuration, it is easy to insert a finger into the finger hole.

In the above configuration, the upper end edge of the side wall is configured as a placement part on which the lid is placed, and when the lid is placed on the placement part and closes the opening, Preferably, the upper edge of the handle portion is located at approximately the same position as the upper surface of the lid.

According to the above configuration, when the opening of the container is closed with the lid, the protrusion length of the handle from the top surface of the lid is suppressed. Therefore, the handle portion is less likely to get in the way when the container is housed inside the outer container or when a plurality of containers are stacked one on top of the other. Note that approximately the same height here refers to cases where the height of the top surface of the lid and the top edge of the handle are completely the same, and also when the height of the top edge of the handle is the same as the height of the top of the lid. This includes cases where it is a little higher or a little lower than the top surface. Specifically, this includes cases where the difference in height between the top surface of the lid and the top edge of the handle is up to about 10 mm.

In order to solve the above-mentioned problem, the assembled container of the present invention includes the above-mentioned container and an outer container that can accommodate the above-mentioned container inside.
According to the above configuration, since volume loss of the container can be suppressed, the outer container can be made more compact.

In the above configuration, preferably, when the container is housed inside the outer container, a gap is formed between the outer surface of the handle portion and the inner surface of the outer container.
According to the above configuration, when the container is housed inside the outer container, it is easy to grip the handle portion of the container.

In the above configuration, the outer container can accommodate the two containers, and when the two containers are accommodated, the gap between the side surface of the recess and the inner surface of the handle portion is It is preferable that the gap be larger than the gap between the outer surface of the handle portion and the inner surface of the outer container.

According to the above configuration, even when two containers are housed, it is easy to insert fingers into the recess, and the handle portion can be firmly gripped by the fingers inserted into the recess. Thereby, the container can be smoothly taken out from the outer container, and the container can be smoothly stored inside the outer container. Moreover, even when the difference between the outer dimensions of the container and the inner dimensions of the outer container is reduced to ensure a large volume of the container, the handle portion is easy to grip.

According to the present invention, it is possible to suppress volume loss of the container that can be accommodated inside the outer container.

As shown in FIG. 2, an opening 15 that opens upward is formed at the upper end edge of the short side wall 12 and the long side wall 13. In the following description, the upper and lower sides of the assembled container 1 will be defined with the outer container 10 placed on a horizontal ground with the opening 15 facing upward.

As shown in FIGS. 2 and 8, a peripheral wall 16 is formed at the upper end portions of the short side wall 12 and the long side wall 13 so as to surround the outer surfaces thereof. The upper edges of the short side wall 12 and the long side wall 13 and the upper edge of the peripheral wall 16 are connected by a connecting wall 17 extending in the horizontal direction. The connecting wall 17 functions as a mounting portion on which the outer container lid 20 is mounted.

As shown in FIG. 2, a grip portion 18 extending in the width direction is formed in the pair of short side walls 12 at an intermediate position in the width direction of the upper end portion. The gripping portion 18 has a downward substantially L-shaped cross section. The outer container main body 11 can be lifted by hooking a finger from the lower side of the grip part 18. The upper surface 18a of the grip part 18 is located at the same height as the upper surface 17a of the connecting wall 17. The upper surface 18a of the gripping portion 18 functions as a mounting portion on which a gripping portion 26 of an outer container lid 20, which will be described later, is placed.

As shown in FIGS. 1 and 2, a buckle 19 is rotatably attached to the upper end portions of the pair of short side walls 12 in such a manner as to sandwich the grip portion 18 therebetween. When the outer container lid 20 is placed on the outer container main body 11 and the buckle 19 is rotated upward, the connecting portion 19b of the buckle 19 comes into contact with the upper surface of the grip portion 26 of the outer container lid 20, which will be described later. Then, the outer container lid 20 is fixed to the outer container main body 11. In this state, the outer container 10 can be lifted by hooking a finger from below the connecting portion 19a of the buckle 19. Furthermore, in order to remove the outer container lid 20 from the outer container main body 11, the buckle 19 may be rotated downward to release the fixation by the connecting portion 19b.

Legs (not shown) are formed protruding from the lower surface of the bottom wall 14 of the outer container body 11. The legs are formed as protrusions extending along the short side wall 12 and the long side wall 13 at the four corners of the lower surface of the bottom wall 14 .

As shown in FIGS. 1 and 3, the outer container lid 20 has a rectangular shape in top view and includes an upper wall 21, an upper wall 22, a lower wall 23, and a mounting wall 24. A plurality of ribs 25 are formed on the lower surface of the outer container lid 20 so as to extend in the longitudinal direction and the lateral direction. The outer container lid 20 is reinforced by a plurality of ribs 25.

On the side edge of the outer container lid 20 in the longitudinal direction, a grip portion 26 extending in the lateral direction is formed at an intermediate position in the lateral direction. The grip portion 26 is integrally formed to protrude from the upper wall 22 at a portion where the lower wall 23 and the placement wall 24 are cut out. As shown in FIG. 3, a plurality of reinforcing ribs 27 are formed on the lower surface of the grip portion 26. As shown in FIG.

As shown in FIGS. 1 and 7, the inner circumference of the lower wall 23 is slightly larger than the outer circumference of the peripheral wall 16 of the outer container body 11. Further, the size of the inner circumference of the upper wall 22 is slightly smaller than the size of the inner circumferences of the short side wall 12 and the long side wall 13 of the outer container main body 11. Therefore, when the outer container lid 20 is placed on the outer container main body 11, the mounting wall 24 of the outer container lid 20 is placed on the connection wall 17 of the outer container main body 11, and the The outer surface of the peripheral wall 16 is covered by the lower wall 23 of the outer container lid 20. Thereby, the outer container lid 20 closes the opening 15 of the outer container main body 11. At this time, the grip portion 26 of the outer container lid 20 is placed on the upper surface 18a of the grip portion 18 of the outer container body 11.

As shown in FIGS. 1 and 7, a recess 28 that is recessed downward is formed on the upper surface of the upper wall 21 of the outer container lid 20. As shown in FIGS. The recess 28 has a rectangular shape when viewed from above. The size of the recess 28 is slightly larger than the outer surface of a leg (not shown) as a protrusion formed on the lower surface of the bottom wall 14 of the outer container body 11. Therefore, when the outer container main body 11 of another outer container 10 is stacked on the outer container lid 20 of one outer container 10, the inside of the recess 28 of the outer container lid 20 of the lower outer container 10 The legs (not shown) of the outer container main body 11 of the upper outer container 10 can be accommodated in the upper outer container 10 . Thereby, it is possible to stack the plurality of outer containers 10 in the vertical direction, and it is possible to suppress the collapse of the cargo when stacked.

<About the container 30>
As shown in FIGS. 2, 4 to 6, and 8, the container 30 includes a container body 40 and a lid 50.

As shown in FIGS. 2 and 8, the height of the container 30 is slightly lower than the height of the outer container body 11. Further, the size of the container 30 when viewed from above is approximately half the size of the outer container main body 11. Therefore, when two containers 30 are accommodated inside the outer container main body 11, the two containers 30 can be accommodated in a state where wobbling is suppressed.

The container body 40 is formed into a rectangular parallelepiped box shape having a pair of opposing short side walls 41 and long side walls 42, and a bottom wall 43. The short side wall 41 and the long side wall 42 are formed with substantially the same thickness throughout. An opening 44 that opens upward is formed at the upper end edge of the short side wall 41 and the long side wall 42 . The upper end edges of the short side wall 41 and the long side wall 42 function as a mounting portion on which a mounting wall 54 of a lid body 50, which will be described later, is mounted.

As shown in FIGS. 4 and 6, the pair of short side walls 41 have a side wall recess 45 at an intermediate position in the width direction that extends throughout the entire vertical direction and is recessed inward from the outer surface of the short side walls 41. It is formed. The side wall recess 45 is formed by bending the short side wall 41 inward. Therefore, as shown in FIG. 6, the inner surface of the short side wall 41 corresponding to the side wall recess 45 forms a side wall protrusion 45a that projects inward.

As shown in FIGS. 6 and 8 , a handle portion 46 having the same width as the side wall recess 45 is formed at the upper end edge of the side wall recess 45 in a shape that projects upward from the upper end edge of the short side wall 41 . The handle portion 46 is formed such that, when the container 30 is housed inside the outer container 10, the upper edge 46b of the handle portion 46 has a height slightly lower than the upper surface 17a of the connecting wall 17 of the outer container main body 11. has been done. Since the upper surface 17a of the connecting wall 17 is located at the same height as the upper surface 18a of the gripping part 18, the upper edge 46b of the handle part 46 has a height slightly lower than the upper surface 18a of the gripping part 18.

A finger hole 47 is formed in the handle portion 46 and extends through the handle portion 46 in the thickness direction. The lower end edge 47a of the finger hole 47 is located at approximately the same height as the upper end edges of the short side wall 41 and the long side wall 42. Ribs 46a projecting outward are formed on the outer periphery of the handle portion 46 and on the outer periphery of the finger hole 47 in the handle portion 46. The outer surface of the portion of the handle portion 46 where the rib 46a is not formed is flush with the outer surface of the side wall recess 45.

As shown in FIGS. 4 and 6, a long side wall recess 48 is formed at the lower end of the pair of long side walls 42, extending in the width direction and recessed inward from the outer surface of the long side wall 42. The long side wall recess 48 is formed by bending the long side wall 42 inward. Therefore, as shown in FIG. 6, the inner surface of the long side wall 42 corresponding to the long side wall recess 48 forms a long side wall convex portion 48a that projects inward.

Legs (not shown) are formed protruding from the lower surface of the bottom wall 43 of the container body 40. The legs are formed as protrusions that protrude downward from the lower surface of the bottom wall 14 along the periphery of the bottom wall 14 .

As shown in FIGS. 4, 5, and 7, the lid 50 is formed into a rectangular shape in top view, and includes an upper wall 51, an upper wall 52, a lower wall 53, and a mounting wall 54. The size of the inner periphery of the lower wall 53 is slightly larger than the size of the outer periphery of the short side wall 41 and the long side wall 42 of the container body 40. Further, the size of the inner circumference of the upper side wall 52 is slightly smaller than the size of the inner circumferences of the short side wall 41 and the long side wall 42. Therefore, when the lid 50 is placed on the container body 40, the mounting wall 54 of the lid 50 is placed on the upper edge of the short side wall 41 and the long side wall 42 of the container body 40, and A lower wall 53 of the lid body 50 covers the outer surfaces of the short side wall 41 and the long side wall 42 . Thereby, the lid 50 closes the opening 44 of the container body 40.

As shown in FIG. 5, downwardly recessed recesses 55 are formed on both longitudinal edges of the lid 50. As shown in FIG. The recess 55 is formed into an L-shaped cross section with a side wall 56 and a lower wall 57. The length of the recess 55 in the lateral direction of the lid 50 is slightly longer than the width of the handle 46 of the container body 40.

As shown in FIG. 8, when the lid 50 closes the opening 44 of the container body 40, the lower edge 47a of the finger hole 47 of the handle 46 is connected to the lower wall 57 of the recess 55 of the lid 50. It is located at approximately the same height as the upper surface 57a. Therefore, the finger hole 47 is in communication with the recess 55. Further, the upper end edge 46b of the handle portion 46 is located at approximately the same position as the upper wall 51 of the lid body 50, and is located at a slightly higher height than the upper surface of the upper wall 51. Specifically, the upper edge 46b of the handle portion 46 is located at a height approximately 10 mm higher than the upper surface of the upper wall 51 of the lid body 50. Note that the difference between the upper edge 46b of the handle portion 46 and the upper surface of the upper wall 51 of the lid body 50 is preferably about 10 mm, and more preferably about 5 mm.

As shown in FIG. 5, a recess 58 that is recessed downward is formed on the upper surface of the upper wall 51 of the lid 50. As shown in FIG. The recess 58 has a rectangular shape when viewed from above. The size of the recess 58 is slightly larger than the outer surface of a leg (not shown) as a protrusion formed on the lower surface of the bottom wall 43 of the container body 40. Therefore, by storing the legs of the container body 40 of the upper container 30 in the recess 58 of the lid 50 of the lower container 30, it is possible to stack a plurality of containers 30 in the vertical direction. It is possible to suppress the collapse of cargo when stacked.

<About assembled container 1>
Next, the assembled container 1 in which the container 30 is housed inside the outer container 10 will be described along with its function.

The container body 40 of the container 30 that can be accommodated inside the outer container 10 is formed to be about half the size of the outer container body 11 when viewed from above. Moreover, two containers 30 can be accommodated inside the outer container 10. Therefore, when two containers 30 are housed inside the outer container 10, no large gap is formed between the outer surface of the containers 30 and the inner surface of the outer container 10.

When taking out the container 30 from the inside of the outer container 10, after removing the outer container lid 20 from the outer container main body 11, grasp the pair of handles 46 formed on the container main body 40 of the container 30 and remove the container 30. lift.

As shown in FIG. 8, a side wall recess 45 is formed in the short side wall 41 of the container body 40 of the container 30, and the outer surface of the handle portion 46 is flush with the outer surface of the side wall recess 45. Therefore, a gap A is formed between the outer surface of the handle portion 46 and the inner surface of the short side wall 12 of the outer container body 11.

The lower edge 47a of the finger hole 47 of the handle portion 46 is located at approximately the same height as the upper surface 57a of the lower wall 57 of the recess 55 of the lid body 50, and the finger hole 47 communicates with the recess 55. There is. A gap B is formed between the outer surface (side surface) of the side wall 56 of the recess 55 and the inner surface of the handle portion 46. Gap B is larger than Gap A.

When taking out the container 30 from the inside of the outer container 10, insert a finger into the finger hook hole 47 from the outside of the handle portion 46 and put the fingertip into the recess 55. At this time, fingers can be easily inserted into the gap A formed by the side wall recess 45 formed in the container body 40. Since the handle portion 46 is formed to protrude from a part of the short side wall 41 in the width direction, it is easily bent inward of the container body 40 by inserting a finger, and this also facilitates insertion of the finger. Furthermore, since the lower edge 47a of the finger hook hole 47 and the upper surface 57a of the lower wall 57 of the recess 55 are located at approximately the same height, insertion of the finger from the finger hook hole 47 toward the recess 55 is smooth. . Further, since the gap B is larger than the gap A, the handle portion 46 can be firmly gripped by the fingers inserted into the recess 55. Lift the container 30 while gripping the handle portion 46 and take out the container 30 from the inside of the outer container 10.

Conversely, when storing the container 30 inside the outer container 10, the handle portion 46 is grasped, the container 30 is lifted, and the container 30 is stored inside the outer container main body 11. After housing the container 30, the grip portion 26 of the outer container lid 20 is grasped and lifted to close the opening 15 of the outer container body 11 with the outer container lid 20. The buckle 19 is rotated to fix the outer container lid 20 to the outer container main body 11.

Note that when taking out the container 30 from the inside of the outer container 10 or storing the container 30 inside the outer container 10, insert your finger into the finger hole 47 from the inside of the handle portion 46, that is, from the recess 55 side. It is also possible to insert it and hold the handle portion 46 with the opposite hand. Also at this time, since the gap B is larger than the gap A, interference between the base of the fingers and the back of the hand with the side wall 56 of the recess 55 is suppressed. The handle portion 46 is easy to hold.

As shown in FIG. 8, in the container 30 housed inside the outer container 10, the upper edge 46b of the handle portion 46 is located at a lower height than the short side wall 12 and the long side wall 13 of the outer container main body 11. There is. That is, the upper edge 46b of the handle portion 46 is located at a lower height than the upper surface 17a of the connecting wall 17 of the outer container body 11 on which the outer container lid 20 is placed. Therefore, when the outer container lid 20 is placed on the outer container main body 11, the handle portion 46 is prevented from interfering with the outer container lid 20.

According to this embodiment, the following effects can be obtained.
(1) The short side wall 41 of the container 30 is provided with a handle portion 46 having a finger hole 47 that extends upward from the upper edge and penetrates in the thickness direction. Therefore, volume loss of the container 30 with respect to the outer container 10 can be suppressed compared to a container in which the handle portion extends horizontally outward.

(2) A recess 55 recessed downward is formed on the side edge of the lid 50. When the lid 50 closes the opening 44 of the container body 40, the finger hole 47 communicates with the recess 55. Therefore, the length of the handle portion 46 protruding from the lid body 50 can be reduced. While suppressing volume loss of the container 30 with respect to the outer container 10, it is possible to prevent the handle portion 46 of the lower container 30 from interfering with the upper container 30 when the containers 30 are stacked vertically. can.

(3) When the lid 50 closes the opening 44 of the container body 40, the finger hole 47 communicates with the recess 55. Therefore, when taking out the container 30 from inside the outer container 10 or storing the container 30 inside the outer container 10, the work can be done without removing the lid 50 of the container 30.

(4) A side wall recess 45 recessed inward is formed below the handle portion 46 on the outer surface of the short side wall 41 of the container body 40. The outer surface of the handle portion 46 is formed flush with the outer surface of the side wall recess 45. Therefore, the outer surface of the handle portion 46 is recessed inward from the outer surface of the short side wall 41 in the portion where the handle portion 46 is not formed. Even when there is almost no gap between the inner surface of the outer container body 11 and the outer surface of the container 30, a gap A is formed between the inner surface of the outer container body 11 and the outer surface of the handle part 46. This makes it easy to insert fingers into the finger hook hole 47 of the handle portion 46. The container 30 can be easily taken in and out of the outer container 10 while suppressing volume loss of the container 30.

(5) The short side wall 41 and the long side wall 42 of the container body 40 are formed to have substantially the same thickness throughout. The side wall recess 45 is formed in a shape in which the short side wall 41 is bent inward, and the inner surface of the short side wall 41 corresponding to the side wall recess 45 is formed as a side wall protrusion 45a that projects inward. It is formed. By forming the side wall recess 45, the rigidity of the short side wall 41 is improved, and the rigidity of the container body 40 is improved.

(6) The long side wall recess 48 is formed in a shape in which the long side wall 42 is bent inward, and the inner surface of the long side wall 42 corresponding to the long side wall recess 48 has a shape that projects inward. It is formed as a long side wall convex portion 48a. By forming the long side wall recess 48, the rigidity of the long side wall 42 is improved, and the rigidity of the container body 40 is improved.

(7) When the lid 50 closes the opening 44 of the container body 40, the lower edge 47a of the finger hole 47 is located at approximately the same height as the upper surface 57a of the lower wall 57 of the recess 55 of the lid 50. are doing. Therefore, when inserting a finger from the finger hook hole 47 toward the recess 55, the fingertip is unlikely to get caught on the lower wall 57 of the recess 55. You can insert your fingers smoothly.

(8) The upper edges of the short side wall 41 and the long side wall 42 function as a placement portion on which the lid 50 is placed. When the lid 50 is placed on the upper edges of the short side wall 41 and the long side wall 42 and closes the opening 44, the upper edge 46b of the handle 46 is at approximately the same position as the top surface of the lid 50. Therefore, it is located at a height of about 10 mm higher than the upper surface of the upper wall 51 of the lid body 50.

Therefore, when the opening 44 of the container body 40 is closed with the lid 50, the protrusion length of the handle 46 from the top surface of the lid 50 is suppressed. When storing the container 30 inside the outer container 10 or when stacking a plurality of containers 30 in the vertical direction, the handle portion 46 is unlikely to get in the way.

(9) Two containers 30 can be accommodated inside the outer container 10. When the two containers 30 are housed inside the outer container 10, a gap A is formed between the outer surface of the handle portion 46 and the inner surface of the short side wall 12 of the outer container body 11. Further, in the container 30, a gap B is formed between the outer surface of the side wall 56 of the recess 55 and the inner surface of the handle portion 46. The gap B is larger than the gap A. Therefore, it is easy to insert a finger into the recess 55 from the finger hook hole 47. The handle portion 46 can be firmly gripped with the fingers inserted into the recess 55.

(10) In the container 30 housed inside the outer container 10, the upper edge 46b of the handle portion 46 is located at a lower height than the short side wall 12 and the long side wall 13 of the outer container 10.
