In order to prevent this, the corners of each of the accommodation recesses 2a to 2c are curved in a planar shape. At the bottom of each of the accommodation recesses 2a to 2c, there is formed a base 5 on which an object can be placed, and at the periphery of the base, a groove 6 capable of storing a fluid component or a liquid component. Are formed.

The plurality of housing recesses 2a to 2c are respectively
The container body 1 is defined by a partition wall 3 having a flat upper end surface (flat surface) 3a corresponding to a reference surface (sheet surface) of the sheet, and a flat upper end surface (flat surface) A peripheral wall 7 having a U shape and having a U-shaped cross section is formed so as to be continuous with the partition wall 3. That is, the upper edges of the inclined side walls 4 of the plurality of accommodation recesses 2a to 2c are connected to the partition wall 3 and the peripheral wall 7 having a U-shaped cross section to be erected through the narrow flat surface 3a. Multiple accommodation recesses 2
a to 2c are independent from each other by the partition wall 3 and the peripheral wall 7 respectively. The flat surface 3a of the partition wall 3 and the flat surface 7a of the peripheral wall 7 are also continuous, and form substantially the same plane corresponding to the reference surface (sheet surface) of the sheet.

The flat surface 3a of the partition wall 3 is formed wider than the peripheral wall 7, and the width of the flat surface 3a of the partition wall 3 is larger than the width of the flat surface 7a of the peripheral wall 7. Is formed. In particular, the partition walls 3 are formed to extend in a curved manner in a plane Y-shape, and a large area is provided in a gathering area where the partition walls 3 gather or an intersection area where the partition walls intersect (a central portion in this example). A flat portion 3b is formed. Furthermore, partition wall 3
The partition wall 3 is also curved in the gathering region or the intersection region between the partition wall 3 and the peripheral wall 7, and a flat portion 7b having a large area is formed. The flat surface 3a of the partition wall 3 may be formed to have substantially the same width as the peripheral wall 7, or may be formed to be narrower than the peripheral wall 7. Further, the partition wall 3 and the peripheral wall 7 are respectively an upper flat surface 3a of an upper wall defining a base flat surface (sheet reference surface) of the container body 1 and a side flat surface of a side wall extending from the upper flat surface. 3c.

Further, in order to improve the degree of fitting with the lid 11, the partition wall 3 and the peripheral wall 7 are each formed such that the distance between the side walls becomes narrower from the opening of the container body 1 toward the bottom. It has a shape (a dovetail-shaped cross-sectional shape). In this example, both side walls of the partition wall 3 and the peripheral wall 7 are
Are formed slightly narrower from the opening to the bottom, and 4-8 from the bottom of the housing recesses 2a-2c toward the opening with respect to the vertical line from the reference surface of the sheet of the container body 1. It is inclined outward at an angle of about °.

On the other hand, the lid 11 has a flat portion 3d interposed between the partition wall 3 and the peripheral wall 7 of the container body 1 and the storage recesses 2a to 2c corresponding to the plurality of storage recesses 2a to 2c.
A plurality of bulging recesses (bulging portions) 1 having an inclined wall portion 14 having a larger diameter on the opening side via a flat portion 14a wider than that.
2a to 12c are formed. Also, the lid 11 has
A first fitting portion (fitting recess) 13 having a U-shaped cross section that can be fitted to the partition wall 3 of the container body 1, and a U-shaped cross section that can be fitted to the peripheral wall 7 of the container body 1. A second fitting portion (fitting recess) 17 is formed. As with the housing recesses 2a to 2c of the container body 1, a plurality of bulging recesses 1 of the lid 11 are provided.
Each of 2a to 12c is partitioned by the first fitting portion 13 and the second fitting portion 17 and is independent.

Further, the first fitting portion 1 having a U-shaped cross section
Each of the third and second fitting portions 17 has an upper wall having a flat surface 13a corresponding to a reference surface (sheet surface) of the sheet, and an inner surface 13a of the upper wall fits with the container body 1. In some cases, the upper and lower flat surfaces 3a of the partition wall 3 and the peripheral wall 7 can make surface contact. The first fitting portion 13 having a U-shaped cross section
Further, both side walls of the second fitting portion 17 bulge with respect to a vertical line from the reference surface of the sheet of the lid 11 corresponding to the side walls of the partition wall 3 and the peripheral wall 7 of the container body 1. Recesses 12a-12
c is inclined inward at an angle of about 4 to 8 degrees from the bottom toward the opening.

The container body 1 and the lid 11 can be stacked, respectively, in order to reduce the storage and transportation volume. Narrow flanges (flanges) 8 and 18 are formed on the periphery of the container body 1 and the lid 11, and at each corner of the container body 1 and the lid 11,
Stripping margins 9 and 19 are formed to easily release the fitting between the fitted container body 1 and the lid 11.

The inner wall (flat surface) 13a of the first fitting portion 13 formed on the lid 11 is in contact with the flat surface 3a of the partition wall 3 as it is fitted to the partition wall 3. The inner wall (flat surface) 17a of the second fitting portion 17 is brought into surface contact with the flat surface 7a of the peripheral wall 7 as the peripheral wall 7 is fitted. It is possible. In this example, the inner surfaces (flat surfaces) 13a, 17a of the upper walls of the first fitting portion 13 and the second fitting portion 17 are fitted to the container main body 1 so that the upper surfaces of the partition wall 3 and the peripheral wall 7 are formed. It constitutes a contact portion capable of surface contact with the flat surfaces 3a, 7a.

In such a container, a plurality of accommodation recesses 2a
Even if different foods, particularly foods containing a fluid component, are stored and tilted in 2c to 2c, the fitting and close contact between the partition wall 3 of the container main body 1 and the first fitting portion 13 of the lid 11 can be achieved. Thus, it is possible to effectively prevent the flowable component from flowing into the adjacent storage recesses 2a to 2c. In particular, the accommodation recesses 2a to 2c whose corners are curved in a planar shape allow the fluid component to be concentrated along one of the accommodation recesses 2a to 2c without concentrating the fluid component at one location of the accommodation recesses 2a to 2c. Since it can be dispersed and the area of the flat surface 3b in the gathering area or the intersection area is large, it is possible to reliably prevent the fluid component from flowing into the adjacent accommodation recesses 2a to 2c. Also, the fitting and surface contact between the peripheral wall 7 of the container body 1 and the second fitting portion 17 of the lid 11 can reliably prevent the fluid component from leaking or flowing out of the container. In particular, the partition wall 3 and the peripheral wall 7 of the container body 1, and the first and second fitting portions 13, 17 of the lid 11
Are formed so as to be continuous with each other by molding of a thin plastic sheet.
17 has high elasticity and resilience, and the container body 1 and the lid 11
Can be tightly fitted, and the fit can be easily released.

It is sufficient that a plurality of housing recesses are formed in the container body, and the number of housing recesses is not particularly limited, and is usually about 2 to 7 (especially 2 to 5). The shape of the accommodation recess is not particularly limited and can be selected according to the number and arrangement of the accommodation recesses, and it is not necessary to incline the side wall. Further, it is not always necessary to form a pedestal at the bottom of each accommodation recess, and the shapes of the pedestal and the groove are not particularly limited, and can be appropriately selected according to the shape of the accommodation recess, for example, a lattice shape or the like. It may be.

In the planar shape, it is not necessary to bend the corner portion of the accommodation recess, but it is possible to improve the appearance and prevent the fluid component from concentrating on a specific portion of the accommodation recess when the container is inclined. In order to achieve this, it is preferable that the corners are curved. In addition, in the set or intersection area of each partition wall (and / or the set or intersection area of each partition wall and the peripheral wall), each partition wall is curved to be wide and gathered to have a large area (or a larger area than each partition wall). It is also preferable to form a flat surface having a large width or area.

The sectional shape of the partition wall and the peripheral wall formed in the container body may be, for example, an upper wall bulging outward and curved and a flat side wall as long as it has a flat surface. Alternatively, the upper wall may be flat, and the side wall may be bulged to the side and curved. In order to improve the degree of fitting between the container body and the lid and to facilitate detachment of the lid from the container main body, the partition walls and both side walls of the peripheral wall are, as described above,
It is preferably in the form of a dovetail that narrows from the opening of the container body to the bottom, and the side walls are usually 1 to 10 ° (preferably 3 °) with respect to a vertical line from a reference horizontal line of the container body.
９9 °, especially 4-8 °).

In order to effectively control the flow of the fluid component into the adjacent receiving recess, the preferred partition wall and / or peripheral wall has a cross-sectional shape that becomes narrower from the opening of the container body toward the bottom. In addition, the lid has a fitting portion that can be fitted to the partition wall and the peripheral wall of the container body.

The flat surfaces of the partition wall and the peripheral wall can be constituted by an upper flat surface of an upper wall and a side flat surface of a side wall rising from the base flat surface of the container body. It is sufficient that at least one of the flat surfaces can contact the contact portion of the lid.

The width of the flat surface of the partition wall is not particularly limited as long as the inflow of the fluid component between the adjacent storage recesses can be suppressed. For example, the width of the flat surface of the peripheral wall may be equal to or smaller than the width of the flat surface of the peripheral wall. Good. Furthermore, it is not necessary to make the area of the gathering area where each of the partition walls that partition the plurality of housing recesses or the intersection area where each of the partition walls intersects need to be wider than each of the partition walls, but the mixing of the fluid component is effective. In order to prevent this, the intersection area preferably has a flat surface having a larger area than each partition wall.

The lid need not be independent of the container body as long as it can be detachably fitted to the container body, and may be hingedly connected to the container body. The lid does not need to have a plurality of bulging portions corresponding to the accommodation recesses of the container main body, and has at least a contact portion capable of contacting the partition wall of the container main body, and is fitted to the peripheral wall. Any combination is acceptable.

In order to restrict the flow of a fluid component (such as a liquid component such as broth) from flowing into the adjacent storage recess, the lid can at least contact the flat surface of the partition wall (particularly at least line contact). It is sufficient if a contact portion is provided that is capable of contact, especially surface contact. Furthermore, in order to restrict the fluid component (such as a liquid component such as broth) from leaking or flowing out of the container, the lid is at least capable of contacting the flat surface of the peripheral wall (particularly at least capable of linear contact, Among them, it is preferable to have a contact portion capable of surface contact. These contact portions are not only the upper flat surface of the partition wall and / or the peripheral wall, but also at least one flat surface selected from the side flat surface of the partition wall and / or the peripheral wall, and the base flat surface of the container body. It may be a contact portion with a surface. It is preferable that the contact portion of the lid is constituted by a contact portion with at least an upper flat surface of the partition wall and / or the peripheral wall.

The contact portion of the lid need not be formed in the first fitting portion as long as the contact portion of the lid can be brought into contact with the partition wall of the container main body when the lid is fitted to the container main body. In order to effectively restrict the flow of the fluid component into the adjacent accommodation recess, the first fitting portion is preferably formed.

A contact portion between the container body and the lid (particularly, a contact portion between the partition wall and / or the peripheral wall of the container body and the first fitting portion and / or the second fitting portion of the lid). In order to effectively prevent the fluid component from flowing into the adjacent storage recess or flowing out of the container, a liquid reservoir may be formed. The liquid reservoir may be formed by a concave portion formed in at least one of the container body and the lid in the contact portion, and the concave portion may be formed by the partition wall and the peripheral side portion (and / or the first peripheral portion). It may be formed continuously or discontinuously (regularly or randomly) along the fitting portion and the second fitting portion). In the case where the liquid reservoir concave portion is formed continuously, it may be formed in one line or in plural lines. Further, a concave portion having a large volume may be formed in the gathering region or the intersection region of the partition walls in order to improve the liquid storage capacity, and a radial groove or the like may extend from the concave portion.

The container body and the lid can be formed of various molding materials (for example, paper), but are usually formed of a plastic sheet (for example, a styrene resin sheet, an olefin resin sheet, etc.). The plastic sheet is not limited to a single-layer sheet, but may be a composite sheet.

The present invention is effective as a container for packaging foods containing fluid components (such as boiled foods and prepared dishes) in various foods, particularly a plurality of foods of different types.

[0034]

According to the present invention, a plurality of housing recesses are defined by the partition wall, and the contact portion of the lid comes into contact with the flat surface of the partition wall as the container body and the lid are fitted. Therefore, even if the soup food is stored in the storage recess, it is possible to reliably prevent the fluid component (liquid component such as juice) from being mixed into the food in the adjacent storage recess. In addition, since the fitting portion of the lid can be fitted to the peripheral wall of the container body, even if a plurality of different types of food are stored, the fluid component (such as a liquid component such as broth) is stored in another container. It is possible to prevent inflow and mixing into the concave portion, and to reliably prevent outflow to the outside.
