Description

  The present invention relates to a container body of a food packaging container that contains vegetables, meats, prepared vegetables and the like used for sale or take-out.

Food packaging containers that are used in convenience stores and supermarkets and store vegetables, meat, and prepared dishes for sale are molded from a synthetic resin sheet and raised from the bottom to form a bottom, and from the bottom edge It is comprised from the dish-shaped container main body which has a wall part which stands | starts up, and the cover body which is shape | molded from a transparent synthetic resin sheet and covers a container main body.
As an example of such a food packaging container, Japanese Patent Application Laid-Open No. 2002-95429 (Patent Document 1) describes a sushi packaging container.

The sushi packaging container described in Japanese Patent Application Laid-Open No. 2002-95429 (Patent Document 1) appears to be buried in a sill provided on the container body, although the sushi fit is good, and there is no sense of volume. It was. These problems apply not only to sushi, but also to other foods.
Therefore, ingenuity has been made to improve the appearance of the stored food so that the food is visually recognized with a sense of volume.

  For example, the container body 1 shown in FIG. 9 includes a bottom 2 having legs 2a and a side wall 3 rising upward from the periphery of the bottom, and is formed in a dish shape that is substantially rectangular in plan view. And the food mounting part 2b inside the leg part 2a is made into the inclined surface 4 as a device which improves the appearance of food. As shown in the cross-sectional views of FIG. 9 and FIG. 10, the inclined surface 4 includes a front inclined portion 4a and a rear inclined portion 4b that rise from the one side 3a side of the rectangular side wall 3 toward the opposite side 3b side. However, it is comprised as what was continued over 2 steps | paragraphs by the step part 4c.

  The food placed on the inclined surface 4 extending in two stages is more three-dimensionally visible while facing the front of the consumer from the diagonal front of the food packaging container. Therefore, the food can be given a sense of volume, and the overall appearance can be improved.

JP 2002-95429 A

When selling food contained in a food packaging container in a supermarket or the like, it is usual to place several food packaging containers in layers. The container body 1 has legs 2a so that it can be placed stably when placed one by one on a table or the like, but when placed in a stacked manner, the legs 2a are placed on the lid that is underneath. Instead, since the food placing portion 2b inside the leg portion 2a is placed on the lid, there arises a problem that if the food placing portion 2b has the inclined surface 4, it cannot be horizontally stacked.
Accordingly, the present invention provides a container body of a food packaging container that can be stably stacked and displayed even when food packaging containers having inclined surfaces are stacked on the food placing portion of the container body. It was made for the purpose.

  That is, a container body in a food packaging container comprising a container body that contains food and a lid that can be visually recognized from outside and is attached to the container body, the legs projecting downward and the inside of the legs And a side wall that rises upward from an edge of the bottom portion. The food placement portion has an inclined surface, and projects downward from the inclined surface. Provided is a container body in a food packaging container provided with a support protrusion that is engaged with a top surface of a lid when a plurality of packaging containers are stacked.

Since the container main body for containing food constitutes a food packaging container together with a lid that allows food to be visually recognized from outside and is attached to the container main body, the food can be stored while being blocked from the outside. Moreover, when the packaging container for food is provided with a lid, the food can be stacked without damaging the food when the container main body is stacked.
Since the container body is provided with a bottom portion having a leg portion protruding downward and a food placement portion for placing food on the inside of the leg portion, the food placement portion can be raised. Moreover, since the container main body is provided with the side wall that rises upward from the edge of the bottom, it can be accommodated without impairing the shape of the three-dimensional food.

Since the food placing portion has an inclined surface, the food can be seen from the front with respect to the consumer's line of sight from diagonally forward of the food packaging container. Moreover, it can be made to visually recognize with depth and can show food more three-dimensionally. Furthermore, food can be put on a position higher than the base end of the leg by the inclined surface. Therefore, the food can be given a sense of volume, and the overall appearance can be improved.
And since the support protrusion which protrudes below from this inclined surface and latches to the top | upper surface of a cover body when a plurality of this food packaging container was stacked, this support protrusion can be made to contact on a cover body. And the container body can be stably stacked on the lid. In other words, if there is no support protrusion, it is possible to avoid the inconvenience that the inclined body comes into direct contact with the top surface of the lid and the container body is inclined.

The anti-lid locking surface formed by the tip of the support protrusion and the lower base end of the inclined surface is substantially horizontal. When a plurality of food packaging containers are stacked, the support protrusion and the lower base end are covered with each other. It can be set as the container main body latched substantially horizontally with respect to the top | upper surface of a body.
By making the anti-lid locking surface formed by the tip of the support protrusion and the lower base end of the inclined surface substantially horizontal, when a plurality of food packaging containers are stacked, the support protrusion and the lower base end Can be locked substantially horizontally with respect to the top surface of the lid. Therefore, a plurality of food packaging containers can be stacked vertically and stably.

If the support protrusion is provided closer to the center of the inclined surface, a triangle is formed by a straight line portion that is the lower base end of the inclined surface and one point that is the tip of the support protrusion, and is brought into contact with the top surface of the lid. it can. Therefore, the container main body can be stably stacked on the lid.
Further, if food is placed on the food placing portion, the supporting protrusion can be hidden. Therefore, it can be set as the container main body which cannot see presence of a support protrusion from the outside, when food is accommodated.
Furthermore, since it has a support protrusion, the whole food mounting part can be made into an inclined surface. If the whole food placing part is an inclined surface, an ideal arrangement with a good appearance can be performed on the whole food placing part.

The food placing portion is provided with a horizontal portion, and the anti-lid locking surface formed by the tip of the support protrusion and the horizontal portion is substantially horizontal. When a plurality of the food packaging containers are stacked, It can be set as the container main body which a support protrusion and a horizontal part latch substantially horizontally with respect to the top | upper surface of a cover body.
When the food placing portion is provided with a horizontal portion, and the tip of the support protrusion and the anti-lid locking surface formed by the horizontal portion are substantially horizontal, when a plurality of food packaging containers are stacked, The support protrusion and the horizontal portion can be locked substantially horizontally with respect to the top surface of the lid. Therefore, a plurality of food packaging containers can be stacked vertically and stably.

In addition, since the food placing portion has a horizontal portion, in the case of a large-area container body, compared to the case where the entire food placing portion is an inclined surface, the lower end of the inclined surface to the upper end. Can be shortened. Therefore, it is possible to prevent the position of the bottom portion from becoming higher than necessary and the side wall from becoming higher.
In particular, if the support protrusion is provided closer to the center of the inclined surface, the horizontal part located at the lower base end of the inclined surface and the tip of the support protrusion abut against the top surface of the cover body. The container body can be stacked.

  The inclined surface provided in the food placing portion can be an inclined surface formed over a plurality of stages. Since the inclined surface formed over a plurality of stages is provided, a step is generated between the food placed on each of the front inclined part corresponding to the preceding stage and the rear inclined part corresponding to the subsequent stage, and the three-dimensional effect of the food to be placed is further increased. I can feel it. Therefore, the appearance of the food can be further improved.

  Further, a container body in a food packaging container comprising a container body that contains food and a lid that can be visually recognized from the outside and is attached to the container body, the leg portion projecting downward and the leg portion A bottom portion having a food placement portion for placing food on the inside, and a side wall rising upward from an edge of the bottom portion; the food placement portion as an inclined surface, and the inclined surface and four leg portions; There are four horizontal portions in between, and the anti-lid locking surface formed by these four horizontal portions is substantially horizontal. When a plurality of the food packaging containers are stacked, the four horizontal portions are the top of the lid body. Provided is a container body in a food packaging container that is locked substantially horizontally with respect to a surface.

  When four horizontal portions are provided between the inclined surface and the four leg portions, and the anti-lid locking surface formed by the four horizontal portions is substantially horizontal, a plurality of food packaging containers are stacked. It can be set as the container main body which four horizontal parts latch substantially horizontally with respect to the top | upper surface of a cover body. Therefore, a plurality of food packaging containers can be stacked vertically and stably.

  According to the container main body of the food packaging container of the present invention, the food can be more directed toward the front with respect to the consumer's line of sight from the oblique front of the food packaging container, and can be visually recognized more three-dimensionally. In addition, the food can have a voluminous feel and the overall appearance can be improved. Moreover, according to the container main body of the food packaging container of the present invention, even when the food packaging containers provided with the inclined surfaces are stacked and placed, it is possible to stably display the stacked containers.

Embodiments of the present invention will be described with reference to the drawings. In addition, duplication description is abbreviate | omitted about the structure, material, manufacturing method, effect, etc. which are common in each embodiment.
First Embodiment [FIGS. 1 to 4] :
1 and 2 show a container main body 11 of a food packaging container suitable for housing sashimi, such as vegetables, meats and prepared dishes, and FIGS. 3 and 4 show a transparent lid to be attached to the container main body 11. The body 51 is shown. The food packaging container includes the container body 11 and the lid 51.

The container body 11 includes a bottom portion 12 having a leg portion 12a projecting downward, a food placement portion 12b for placing food inside the leg portion 12a, and a side wall 13 rising upward from the peripheral edge of the bottom portion 12. And is formed in a dish shape that is substantially rectangular in plan view.
The side wall 13 engages with the lid at an edge portion 13c provided at the tip thereof.
The leg portions 12a provided on the bottom portion 12 protrude downward at the four corners of the bottom portion 12, and the food packaging container can be placed on a table or the like horizontally with the food placing portion 12b raised.

And the food mounting part 12b made into the raising bottom is formed as the inclined surface 14. FIG. As shown in the sectional views of FIGS. 1 and 2C, the inclined surface 14 includes a front inclined portion 14a and a rear inclined portion that rise from one side 13a side of the rectangular side wall 13 toward the opposite side 13b. 14b is formed as a series of two steps with the stepped portion 14c as a boundary.
A support protrusion 17 protruding downward is formed around the center of the rear inclined portion 14b. The tip of the support protrusion 17 serves as a locking surface 17a that locks to the top surface of the lid, which will be described later, when a plurality of food packaging containers are stacked. The tip of the support protrusion 17 protrudes to a position where it can be horizontally stacked on the lid.

As shown in FIGS. 3 and 4, the lid 51 includes a top surface 52 that covers the top of the food, a flange portion 53 that engages with the container body 11, and a side surface portion 54 that extends from the top surface 52 to the flange portion 53. Is formed into a concave shape that opens downward, and is attachable to the container body 11.
The top surface 52 is formed in a transparent and flat plate shape so that the food contained in the container body 11 can be easily seen.

In order to vertically stack food packaging containers with a lid 51 on the container body 11, the top surface 52 of the lid 51 enters the inside of the leg 12a of the container body 11, and the inside of the leg 12a of the container body 11 Are arranged so that the side surface portion 54 of the lid body 51 is positioned along.
Then, the lower base end 15 of the inclined surface 14 shown in FIG. 2C, that is, the end portion of the front inclined portion 14 a continuous with the one side 13 a of the side wall 13, and the locking surface 17 a that is the distal end of the support protrusion 17. It contacts the top surface 52 of the lid 51.
The flat surface formed by the lower base end 15 and the locking surface 17a is the anti-lid locking surface, and since the anti-lid locking surface is substantially horizontal, it is stacked on the upper side with respect to the lower food packaging container. The food packaging container is placed horizontally.

Both the container body 11 and the lid body 51 can be formed from a synthetic resin sheet material using a thermoforming means such as vacuum forming or pressure forming. The lid 51 is made of a synthetic resin material that is transparent and hardly fogging so that the food of the contents can be easily seen. On the other hand, the container body 11 is preferably provided with various decorations and may be an opaque material.
Examples of the material of the container body 11 and the lid 51 include polystyrene resins such as polystyrene and polystyrene-based copolymers, polyolefin resins such as polyethylene, polypropylene, and olefin-based copolymers, and polyethylene terephthalate. And other various polyester resins such as thermoformable synthetic resins.

The container main body 11 has a sense of volume and can be viewed three-dimensionally when stuffed food, particularly sashimi, is packed. Moreover, when this food packaging container is stacked, it can be stacked stably.
Moreover, since the horizontal part is not provided at the end of the inclined surface unlike the container main body 31 shown in the third embodiment to be described later, the ideal arrangement can be performed using the entire inclined surface 14.

Second Embodiment [FIGS. 5 and 6] :
5 and 6 show a container main body 21 which is another embodiment in which the food placing portion 22b is different from the container main body 11 shown in the previous embodiment. The bottom 22 of the container body 21 according to the present embodiment has a front horizontal portion 24d extending horizontally from one side 13a of the side wall 13, a front inclined portion 24a rising from the front horizontal portion 24d to the opposite side 13b, and a stepped portion. It has an inclined surface 24 formed by a rear horizontal portion 24e extending horizontally across 24c and a rear inclined portion 24b rising from the rear horizontal portion 24e to the opposite side 13b.
The front surface and the right side surface of the container main body 21 appear in the same manner as the container main body 11.

  The support protrusion 17 is the same as the container main body 11 shown in the previous embodiment, but in this embodiment, the rear inclined portion is slightly rearward from the boundary portion between the rear horizontal portion 24e and the rear inclined portion 24b. A support protrusion 17 is provided at a position close to 24b.

  When food packaging containers with a lid 51 on the container body 21 are stacked vertically, the front horizontal portion 24d of the container body 21 and the locking surface 17a that is the tip of the support protrusion 17 are on the top surface 52 of the lid 51. It touches horizontally. Therefore, the stacked food packaging containers can be kept horizontal. This is because the anti-lid locking surface formed by the front horizontal portion 24d and the locking surface 17a is substantially horizontal.

  Further, unlike the container main body 31 shown in the third embodiment to be described later, since there is no horizontal portion at the end of the upper inclined portion that is easily visible from the outside, food can be served with a better appearance than the container main body 31.

Third Embodiment [FIGS. 7 and 8] :
7 and 8 show a container body 31 which is still another embodiment. The bottom 32 of the container main body 31 according to the present embodiment includes a food placing part 32b having a front inclined part 34a, a rear inclined part 34b, and a step part 34c similar to the container main body 11 shown in the first embodiment. However, the support protrusion 17 is not provided on the food placing portion 32b. Further, at the corner of the inclined surface 34, four horizontal portions, lid receiving surfaces 38a, 38b, 38c, 38d, are formed between the four leg portions 12a, 12a, 12a, 12a. The lid receiving surfaces 38 a, 38 b, 38 c, 38 d abut on the top surface 52 of the lid 51.
Note that the front surface and the right side surface of the container body 31 appear in the same manner as the container body 11.

  When the food packaging containers with the lid 51 on the container body 31 are stacked vertically, the four lid receiving surfaces 38a, 38b, 38c provided inside the four legs 12a, 12a, 12a, 12a of the container body 31 are provided. , 38d is in horizontal contact with the top surface 52 of the lid 51. Therefore, the stacked food packaging containers can be kept horizontal. This is because the anti-lid locking surface formed by the four lid receiving surfaces 38a, 38b, 38c, 38d is substantially horizontal.

Variations :
Although the example which provides only one support protrusion 17 in the approximate center part of rear side inclination part 14b, 24b is shown, it can provide not only one but multiple. This is because it is necessary to consider the balance when the container main body is placed on the lid body 51, and providing a plurality of container bodies is more stable. Further, the contact surface with the lid 51 other than the support protrusion 17 is the base end of the inclined surface or the horizontal portion. However, a plurality of support protrusions 17 are provided, and the cover body 51 is formed only by the support protrusion 17. You may make it contact | abut.

In addition, the example shown by the said embodiment and its modification is an illustration, and is not limited to such a form, The arbitrary modification which does not contradict the meaning of this invention is included. That is, a case where a part of the configuration described in the above embodiment is not included, another known configuration, or an alternative configuration is also included in the scope of the present invention.
For example, the leg portions 12 a may be provided at the center portions of the four sides of the bottom portions 12, 22, and 32 instead of being provided at the four corners of the bottom portion 12.
