  The present invention relates to a food container in which a plurality of inner containers containing foods are contained in a resin container main body, and more particularly to a food container in which the plurality of inner containers can be easily taken out from the container main body.

Conventionally, what was published by Unexamined-Japanese-Patent No. 2008-222309 (patent document 1) is known as this kind of food containers, for example. As shown in FIGS. 8 and 9, the food container Sa includes a resin-made rectangular container body 100 having a side portion 102 erected on the bottom portion 101 and having an open opening 103. A rectangular lid 104 made of resin that closes the opening 103 of the container main body 100 and a plurality of resin inner containers 105 accommodated in the container main body 100 are provided. The inner container 105 is formed in a cup shape with an inverted quadrangular frustum shape, and the bottom wall 106 is placed on the bottom 101 of the container body 100 and continuously arranged in a matrix form in the container body 100. The opening edge 103a of the container body 100 is inclined (angle α) in the expanding direction so that a space 107 is formed between the opening edge 103a and the opening edge 105a of the inner container 105.

  When using the food container Sa, the food is put in the inner container 105, the inner container 105 is stored in the container main body 100 side by side without any gap, and then the lid 104 is placed on the container main body 100. In this state, store the product as it is, or store it in a refrigerator, or store it in a freezer. Thereafter, when taking out the food, the lid 104 is removed, the inner containers 105 are taken out one by one, and the food is taken out. In this case, as shown in FIG. 9, since the space 107 is formed between the opening edge 103 of the container body 100 and the opening edge 105a of the inner container 105, as shown in FIG. When a fingertip is hooked on the upper part of one side of 105 and lightly pushed toward the container body 100 side (P direction in the figure), the other side of the inner container 105 is lifted, and the inner container 105 can be easily taken out.

JP 2008-222309 A

By the way, in the conventional food container Sa, the inner container 100 can be easily taken out by lifting the other side of the inner container 100 by lightly pressing one side of the inner container 100 with a finger. However, when the food container Sa is frozen, the bottom wall 106 of the inner container 105 freezes and sticks to the bottom 101 of the container body 100 when the inner container 105 is taken out while the food is frozen. In this case, there is a problem that it is difficult to take out the inner container 105.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a food container in which an inner container can be easily taken out even when the food is in a frozen state.

In order to achieve such an object, the food container of the present invention includes a resin container main body having a side portion standing on the bottom and an open top , and a resin that closes the opening of the container main body. In a food container comprising a made lid and a plurality of resin inner containers accommodated in the container body,
A plurality of first contents having a first opening opening that is continuously opened on the bottom of the container main body so as to form a void when viewed from above in the center of the container main body. A container, and a second inner container disposed in a space formed by the plurality of first inner containers and having an upper open second opening,
Forming an outward first flange on the outer peripheral edge of the first opening of the first inner container;
Forming an outward second flange supported on the first flange of the first inner container on the outer peripheral edge of the second opening of the second inner container;
When the second flange of the second inner container is supported on the first flange of the first inner container, a space is formed to separate the bottom wall of the second inner container and the bottom of the container body. Yes.

  When using this food container, the food is put into a plurality of first inner containers and second inner containers, and first, the first inner container is continuously arranged and accommodated in the container body. Thereby, a void is formed in the central portion of the container body as viewed from above by the plurality of first inner containers. Next, the second inner container is placed in this space, and the second flange of the second inner container is supported on the first flange of the first inner container. Then, the container body is covered with a lid. In this state, the food container containing the food is stored as it is, or is stored in a refrigerator, or is stored in a freezer and frozen. Thereafter, when taking out the food, the lid is removed and the second inner container is taken out first. In this case, since the second flange of the second inner container is supported by the first flange of the first inner container and exposed, the second inner container can be easily lifted by hooking it on the fingertip. It can be easily taken out. In this case, even if the food or the container is frozen in the freezer, a space is formed between the bottom wall of the second inner container and the bottom of the container body. The bottom wall is spaced apart from the bottom of the container body. Therefore, there is no situation where the bottom wall of the second inner container sticks to the bottom of the container body, and the second inner container can be easily taken out. When removing the first inner container after removing the second inner container, a space is formed in the center of the plurality of first inner containers. The first flange can be hooked and lifted, so that the first inner container can be easily taken out.

  And the said space is made into the structure formed by making the height of said 2nd inner container lower than the height of said 1st inner container as needed. Since it is only necessary to reduce the height of the second inner container, it can be easily created.

  Moreover, the said space is set as the structure formed by forming a recess in the part corresponding to the bottom wall of the said 2nd inner container of the bottom part of the said container main body as needed. Since the recess is formed in the bottom of the container body by molding the resin, it can be easily formed.

  Further, if necessary, a step portion is provided on the inner bottom wall on the void side of the first inner container so that the lower surface of the inner bottom wall is positioned higher than the lower surface of the outer bottom wall. Protruding lines that support the lower surface of the inner bottom wall facing the stepped portion are provided, and a portion surrounded by the protruding lines is configured as a recess. Since the step portion is supported by the ridges, the movement of the first inner container to the void side is restricted, and the portion surrounded by the ridges is a recess, so that the bottom wall of the second inner container It is possible to reliably form a space that separates from the bottom of the container body.

If necessary, the inner surface of the lid is joined to the first flange when the first inner container and the second inner container are accommodated in the container body and the opening of the container body is covered with the lid. And a second joining surface that joins and presses the second flange.
Thus, when the opening of the container body is covered with the lid, the first joint surface of the lid is joined to the first flange of the first inner container, and the second joint surface is joined to the second flange of the second inner container. Will come to press. Therefore, a space is formed between the bottom wall of the second inner container and the bottom of the container body, and the bottom wall of the second inner container is separated from the bottom of the container body. Since the second flange presses the contact portion of the first flange of the first inner container supported by the second flange, a moment load can be applied to the first inner container. . For this reason, the non-contact portion of the first flange of the first inner container that does not support the second flange of the second inner container is pressed against the lid side. The sealing property with the lid is improved. As a result, for example, when the food is fluid, it is prevented from flowing and flowing into the adjacent inner container, and the food can be reliably separated and stored.

  Furthermore, it is set as the structure which provided the stopper which controls the movement of the said 1st inner container in the bottom part of the said container main body as needed. Even if the first inner container tries to move in the direction in which they are continuous, the movement is restricted by contacting the stopper. Therefore, the wobble of the food put in the first inner container is suppressed, and the serving can be maintained.

  Furthermore, it is set as the structure which provided the support step part which supports the 1st flange of a said 1st inner container in the inner peripheral part of the opening of the said container main body as needed. The support of the first inner container is stable, the wobbling of the food contained in the first inner container is suppressed, and the serving can be maintained.

  According to the present invention, when taking out the food, the lid is removed, and the second inner container is taken out first. In this case, the second flange of the second inner container is supported by the first flange of the first inner container. Therefore, it can be easily lifted by hooking it on the fingertip, so that the second inner container can be easily taken out. In this case, even if the food or the container is frozen in the freezer, a space is formed between the bottom wall of the second inner container and the bottom of the container body. The bottom wall is spaced apart from the bottom of the container body. Therefore, there is no situation where the bottom wall of the second inner container sticks to the bottom of the container body, and the second inner container can be easily taken out. When removing the first inner container after removing the second inner container, a space is formed in the center of the plurality of first inner containers. The first flange can be hooked and lifted, so that the first inner container can be easily taken out.
