It is configured. However, since the engagement groove 33 is formed at the center of the bottom 31 of the inner container 3, it is difficult to visually recognize the position of the engagement groove 33 when the engagement groove 33 is engaged with the partition wall 27. As a result, there is a problem that it is difficult to perform the engaging work. Furthermore, when the inner container 3 is engaged, the inner container 3 is supported at the center of the bottom portion 31, so that when the food storage position stored in the inner container 3 is biased, etc. Had the problem of poor stability.

  Therefore, it is desired to realize a packaging container that can easily engage the middle container and can satisfactorily stabilize the middle container in the engaged state.

The packaging container according to the present disclosure is:
A packaging container comprising: a container body; a middle container placed on the container body in a state of engaging with the container body; and a lid that covers the container body and the middle container,
The inner container has an inner peripheral wall and a bottom that form a concave storage space for storing an object to be stored, and an outer peripheral wall that surrounds the inner peripheral wall,
An engaging portion of the middle container with the container main body is formed on the outer peripheral wall.

  According to this structure, since the engaging part with the container main body in the middle container is formed on the outer peripheral wall of the middle container, the engaging part is engaged with the container main body while visually confirming the engaging part. can do. Therefore, the engagement of the middle container can be facilitated, and for example, the engagement operation can be easily performed even when the object to be accommodated is accommodated in the accommodation space of the middle container. Moreover, since the engaging part is formed in the outer peripheral wall, the intermediate container is supported at the position of the outer peripheral wall when the intermediate container is engaged. Therefore, for example, even when there is a bias in the accommodation position of the object to be accommodated, the inner container can be satisfactorily stabilized.

As one aspect,
It is preferable that the bottom portion is disposed above the engaging portion.

  According to this configuration, a space can be formed below the bottom of the middle container. Therefore, for example, the space can be used as a storage space for storing an object to be stored, separately from the storage space formed by the inner peripheral wall and the bottom. Moreover, when an object is accommodated in this space, it can suppress that an object is in contact with the lower surface of a bottom part. For example, when the object to be contained is food, the bottom surface of the bottom is prevented from being stained.

As one aspect,

The partition wall includes an annular partition wall that is formed in an annular shape and is provided on the center portion side of the container body,
It is preferable that the middle container is placed on the annular partition wall in a state of being accommodated inside the outer edge of the annular partition wall.

  According to this configuration, the middle container can be prevented from protruding outside the annular partition wall. For example, when the container side accommodation space is arranged outside the annular partition wall, the container side accommodation space and the middle container can be prevented from overlapping when viewed in the vertical direction. Therefore, it is possible to suppress the middle container from becoming an obstacle when taking out the object to be accommodated in the container side accommodation space.

As one aspect,
It is preferable that the outer peripheral wall is formed in a tapered shape that spreads outward in the downward direction.

  According to this configuration, since the external force acting downward on the outer peripheral wall can be dispersed outward, the shape retaining property of the intermediate container against the external force can be improved. For example, when stacking packaging containers, the outer peripheral wall in which the weight of the packaging container located above contacts the lid body from below via the lid body of the packaging container located below Overload. Even in such a case, the outer peripheral wall can distribute the load to the outside, and as a result, the shape of the inner container can be maintained.

More specifically, the overlap length L2 is set to the length in the vertical direction from the upper end of the gently tapered portion 34C1 to the lower end of the engaged recess portion 34C5 in the engaged portion 34C.

  As shown in FIGS. 1 and 2, the lid 7 covers the middle container 5 and the container body 3 in a state where the middle container 5 is placed on the container body 3. The lid body 7 is formed to cover the middle container 5 and the container body 3 from above, and to project downward from the outer edge of the lid body ceiling part 72, while the middle container 5 and the container body 3 are disposed outward. A lid side wall 71 that covers the outer periphery of the container body 3, and an outer peripheral engagement portion 73 that is formed at the lower end of the lid side wall 71 and engages with the outer peripheral engaged portion 37 of the container body 3. The shape of the lid 7 can be appropriately changed according to the shape of the container body 3. In the present embodiment, the lid body 7 is formed in a circular shape in plan view. Thereby, it can be engaged with the container main body 3 formed in a circular shape in plan view. Note that the shape of the lid 7 does not depend on the shape of the middle container 5.

  In the example shown in FIGS. 1 and 2, the lid body 7 includes a displacement prevention portion 72 </ b> A that protrudes upward from the lid body ceiling portion 72. Moreover, as shown in FIG. 1, in this embodiment, the container side 2nd bottom part 32B of the container main body 3 is arrange | positioned above the some container side 1st bottom part 32A arrange | positioned around this. Therefore, the container bottom portion 32 has a shape in which the central portion side is recessed upward. For example, when a plurality of packaging containers 1 are stacked in a state where the lid body 7 is attached to the container main body 3, the container main body 3 of the packaging container 1 located above is packaged below. It is placed on the lid 7 of the container 1 for use. At this time, the displacement prevention portion 72A of the lid body 7 is fitted into the container bottom portion 32 positioned above the same. Thereby, the shift | offset | difference of the horizontal direction of the several packaging container 1 stacked in the up-down direction can be suppressed, and the several packaging container 1 can be stacked with sufficient stability.

  Here, when viewed as a single packaging container 1, it receives some external force even when the middle container 5 is not properly engaged with the container body 3 or when it is properly engaged. In such a case, the middle container 5 may come off from the container body 3. When the middle container 5 is detached from the container main body 3 with the lid body 7 mounted on the container main body 3, dishes (contained objects) pop out from the upper storage space 57 or the second storage space 36B below the upper storage space 57. Different types of dishes may be mixed between the container-side accommodation spaces 36. In such a situation, the middle container 5 slides upward with respect to the container main body 3 with the lid 7 attached to the container main body 3, and the engaging portion 53B gets over the engaged portion 34C. Caused by.

The gap L1 is set to be smaller than the overlapping length L2 between the engaging portion 53B and the engaged portion 34C in the vertical direction. In this example, the inner surface 72F is the lower surface of the lid ceiling portion 72.

  According to such a configuration, even when the middle container 5 slides upward with respect to the container body 3 with the lid body 7 attached to the container body 3, the engaging portion 53B is engaged. The top portion 56 of the middle container 5 contacts the inner surface 72F of the lid body 7 before completely overcoming (disconnecting) the portion 34C. Therefore, the state in which the engaging portion 53B and the engaged portion 34C overlap each other in the vertical direction can always be maintained, and the middle container 5 is detached from the container main body 3 with the lid 7 attached to the container main body 3. This can be suppressed.

  Further, in the present embodiment, in the overlapping length L2 between the engaging portion 53B and the engaged portion 34C, the vertical direction from the upper end portion of the engaged tapered portion 34C4 to the lower end portion of the engaged recessed portion 34C5 is determined. The length is set to the second overlap length L2a. And as shown in FIG. 4, the clearance gap L1 is set smaller than the 2nd overlap length L2a. Accordingly, even when the middle container 5 slides upward with respect to the container body 3 with the lid 7 mounted on the container body 3, the engagement bulging portion 53B3 of the engagement portion 53B is covered. The engaged recess 34C5 does not come off the engaged recess 34C5. Accordingly, it is possible to suppress the middle container 5 from being displaced from the container main body 3 in a state where the lid body 7 is attached to the container main body 3. In this case, naturally, the middle container 5 can be prevented from being detached from the container main body 3. .

  As described above, in the packaging container 1, the engaging portion 53 </ b> B of the middle container 5 with the container body 3 is formed on the outer peripheral wall 53. Therefore, the engaging portion 53B can be engaged with the container body 3 while visually recognizing the engaging portion 53B. For example, when the middle container 5 and the container body 3 are engaged with each other in a state in which food is stored in the upper storage space 57 of the middle container 5, these are engaged while visually confirming the engaging portion 53B. be able to. Accordingly, it is not necessary to use a nerve particularly with respect to the engagement between the middle container 5 and the container main body 3. For example, while taking care not to spill the food stored in the upper storage space 57, Can be easily engaged.

  Further, since the engaging portion 53B is formed on the outer peripheral wall 53, when the intermediate container 5 and the container main body 3 are engaged, the intermediate container 5 is disposed on the outer peripheral wall 53 disposed on the outermost side of the intermediate container 5. It is in a state supported by the position. Therefore, for example, the middle container 5 can be satisfactorily stabilized even when a deviation occurs in the accommodation position of the dish accommodated in the second accommodation space 36 </ b> B of the middle container 5.

  In addition, the packaging container 1 (the container main body 3, the middle container 5, and the cover body 7) of this embodiment can be manufactured using the sheet material which uses a thermoplastic resin as a raw material, for example. Examples of thermoplastic resins include polyolefin resins (polyethylene resins, polypropylene resins, etc.), polystyrene resins (impact polystyrene resins, etc.), and polyester resins (polyethylene terephthalate resins and modified with heat resistance). Polyethylene terephthalate resin, etc.) can be employed. As the sheet material, a foamed sheet material or a non-foamed sheet material can be used, and a laminated sheet obtained by laminating a film or the like can also be used. The packaging container 1 can be molded by thermoforming using the above-described various thermoplastic resin sheets. As specific methods for thermoforming, various methods such as vacuum forming, pressure forming, vacuum / pressure forming, and hot plate forming can be employed.

[Second Embodiment]
