Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hermetically-sealed container used for, for example, storing foods in small portions, and a plurality of hermetically-sealed containers having the same shape are elastically fitted to each other in the vertical direction. The feature is that it can be stored and carried in a stacking state.

[0002]

2. Description of the Related Art Generally, this type of hermetically-sealed container used at home is covered with a lid so that it can be carried in a hermetically sealed state.
Since there is no connecting means attached to each other of the sealed hermetically-sealed containers, there is an inconvenience that the plural hermetically-sealed containers are separated when carried in a hermetically sealed state. In addition, there is a drawback that when a plurality of stacked sheets are housed in a refrigerator, for example, they tend to slip off.

[0003]

Therefore, the problem to be solved by the present invention is that a plurality of sealed containers of the same shape covered with a sealing lid can be firmly stacked on top of each other, and can be stored or carried. It's about making it convenient.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a hermetically sealed container including a container body and a sealing lid having a groove-shaped fitting portion that closely contacts a peripheral portion of the container body. In the container, a grounding part having the same shape and size as the peripheral part of the main body is annularly hung on the bottom surface of the container body, and an upward groove having the same size and size as the fitting part is provided on the peripheral part of the sealing lid. A sealed container provided with a second fitting portion formed in a shape is provided.

As described above, the bottom surface of the bottom of the container body is provided with a grounding portion that hangs in an annular shape and has the same shape and size as the peripheral portion, while the second fitting portion is directed upward at the peripheral portion of the sealing lid. As shown in FIG. 2, the hermetically sealed container provided in FIG. 2 was covered with the hermetically sealing lid by fitting the grounding portion on the bottom rear surface of the container body into the second fitting portion provided upward on the peripheral portion of the hermetically sealing lid. A plurality of sealed containers of the same shape can be firmly stacked on top of each other and firmly.

Further, a bulging portion which is appropriately bulged outward is provided on the peripheral portion of the container body, and the sealing lid fitted to this peripheral portion has an outer edge portion which is pressed against the bulging portion from the outside. When,
According to the second aspect of the present invention, the groove-shaped fitting portion is provided with the inner edge portion that is pressed against the bulging portion from the inner side. In addition, it is possible to obtain a hermetically-sealed container which is excellent in hermeticity and in which the lid and the main body can be easily attached and detached.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially longitudinal front view of the embodiment, and FIG. 2 is a partially cutaway front view for explaining a case where containers are stacked as a use state.

In the drawings showing the embodiment, 1 is a container body with a bottom, and 2 is a sealing lid which is elastically fitted to a peripheral edge portion 3 of the container body 1. The container main body 1 has a grounding portion 4 having the same shape and size as the peripheral edge portion 3 hung in a ring shape on the back surface of the bottom portion. A transparent resin is used for the sealing lid 2, and a downward groove-shaped fitting portion 6 that is in close contact with the peripheral portion 3 of the container body 1 is provided on the peripheral portion 5, and the same shape and size as the fitting portion 6. A second fitting portion 7 formed in an upward groove shape is provided on the upper surface. In the figure, 8 is a sealing lid 2.
It is a knob for opening operation that is integrally formed on the edge of the.

The peripheral portion 3 of the container body 1 is, as shown in the drawing,
A fitting portion 6 of the sealing lid 2 which is provided with a bulging portion 3 ′ which is appropriately bulged toward the outside and which fits with the peripheral edge portion 3 has an outer edge portion a which comes into pressure contact with the bulging portion 3 ′ from the outside. , Is formed in a groove shape with an inner edge portion b which is pressed against the bulging portion 3 ′ from the inner side. The second fitting portion 7 also has an outer edge portion a and an inner edge portion b which are similarly formed, and as shown in FIG. 4 is fitted.

The two container bodies 1 which are vertically stacked via the groove-shaped fitting portions 6 and 7 provided on the upper and lower surfaces of the sealing lid 2 have a peripheral edge portion 3 and a grounding portion 4 respectively from inside and outside. It is elastically sandwiched between the side edges a and b, and is firmly held in the stacked state. In addition, the container body 1 and the corresponding lid 2
The size is arbitrary, but in the embodiment, the inner diameter is about 40 m on each side.
m, square with rounded corners, depth of about 30 mm, made for powdered milk.

In carrying out the present invention, the sealing structure of the peripheral portion 3 on the container body 1 side and the fitting portion 6 on the sealing lid 2 side has various shapes in this type of sealed container. Although not limited to the embodiment shown in the drawings, in the embodiment, a type that can be easily die-cut, easily attached and detached, and has a high sealing effect is adopted. Therefore, it goes without saying that the shapes of the peripheral edge portion 3, the grounding portion 4, and the fitting portions 6 and 7 are not limited to those of the embodiment, and can be appropriately selected in accordance with the gist of the present invention. Further, it can be considered to use it in combination with a rectangular sealed container (not shown) having the same stacking function that allows two container bodies 1 to be housed side by side.

The hermetically sealed container according to the present invention is convenient when, for example, baby food or the like is stored in small quantities and carried or carried in addition to powdered milk. Furthermore, it is desirable to use a material that can be used in a microwave oven as the material of the container.

[0013]

According to the hermetically sealed container of the present invention constructed as described above and used as described above, a plurality of containers having the same shape and covered with a hermetically sealed lid can be firmly stacked on top of each other. So it is especially convenient when carrying a large number. It also has the advantage that it can be placed in and taken out of the refrigerator. The present invention has the advantages as described above, and has the advantage of being highly practical.
