It relates to food containers and other closed containers.

[0002]

2. Description of the Related Art Conventionally, cosmetics, chemicals, wet tissues,
There is an airtight container for storing a container such as a sheet mask or food containing a lotion, and for preventing the container from drying or leaking. As shown in FIG. 8, in this closed container, a connecting body (4) is screwed through a connecting portion (3) to an outer periphery of an opening (2) of the container body (1). Opening (5) of this connecting body (4)
Is rotatably connected via a shaft support (7). Also, a spring material is used for the shaft support (7).
By using (8), the lid is
It is possible to jump up when opening (6). As shown in FIG. 8, an airtight packing (10) is arranged at an interval between the connecting body (4) and the mouth (2) on the inner periphery of the connecting body (4), and the airtight packing (11) is sealed. Holds sex.

[0003] An engaging piece (1) provided on the connecting body (4) is provided.
2) The engagement projection (13) and the engagement elastic piece provided on the lid (6).
By engaging the engagement receiving portion (15) of (14), the lid (6) can be closed against the urging force of the spring material (8). And the push-up piece attached to the connecting body (4)
When (16) is pressed, the lid (6) is pushed up in the opening direction, and the engagement between the engagement projection (13) and the engagement receiving portion (15) is released. And, by the urging force of the spring material (8),
The lid (6) automatically jumps up and opens.

However, the closed container (11) as described above
Since the push-up piece (16) for opening the lid (6) is formed separately from the connecting body (4), the closed container (11)
, The number of parts was increased, and the labor and cost of assembling were increased.

In order to solve the disadvantage of having a large number of components, there are other conventional examples in which a lid and a connecting body are connected by a hinge portion or a sealed container formed without using an airtight packing. There is a problem in use operability such as easy opening and airtightness.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and it is possible to easily open and close a lid of a closed container, and to use this opening and closing means. By integrally molding with the connecting body connected to the lid, the number of parts of the closed container is reduced, and the production is facilitated. In addition, the airtight elastic body for maintaining the airtightness of the airtight container can be integrally formed with the connection main body, thereby reducing the number of parts and obtaining an airtight airtight container. It is.

[0007]

According to the present invention, in order to solve the above-mentioned problems, a first aspect of the present invention is to dispose a connecting body on the outer periphery of a mouth of a container body via a connecting portion. An elastic piece is integrally protruded outwardly from the side surface so as to be elastically deformable, and an engaging piece having an engaging projection on the side surface is vertically projected on the upper surface of the elastic piece. An engagement receiving portion which detachably engages with the projection is projected from a side surface of an engagement elastic piece arranged in a vertical direction, and an upper end of the engagement elastic piece is integrally projected on a lower surface of the lid body, and The body makes it possible to cover the opening of the connecting body communicating with the mouth of the container body, and to enable the lid to be rotatably supported by the connecting body.

According to a second aspect of the present invention, a connecting body is disposed on an outer periphery of an opening of a container body via a connecting portion, and an elastic piece is integrally protruded from a side surface of the connecting body so as to be elastically deformable. On the upper surface of the elastic piece, an engaging piece provided with an engaging projection on a side surface is vertically projected, and an engagement receiving portion that detachably engages with the engaging projection of the engaging piece, The upper end of the engaging elastic piece protrudes from the side surface of the vertically extending engaging elastic piece, the upper end of the engaging elastic piece integrally projects from the lower surface of the lid, and the opening of the connecting main body communicates with the mouth of the container main body. The cover body is rotatably supported on the connecting body and the lid is rotatably supported. And is integrally formed on the inner peripheral wall of the connecting main body.

In addition, the airtight elastic body may be formed with a jumping portion which can press and urge the lid in the opening direction, protruding in the direction of the lid, on the shaft support side of the connecting body and the lid.

[0010]

Since the present invention has the above-mentioned structure,
To open the lid to use the contents of the closed container,
The elastic piece protruding from the side surface of the connecting main body is pressed by a finger in the disengagement direction. By this pressing, the elastic piece is elastically deformed, and the engaging piece provided integrally with the elastic piece slides in the disengaging direction. By this sliding, the engagement between the engagement protrusion provided on the engagement piece and the engagement receiving portion of the engagement elastic piece provided on the lid is released, so that the lid is opened around the pivot portion. Can rotate in any direction. As a result, the opening of the connection main body communicating with the mouth of the container main body is opened, so that the user can perform various operations such as makeup using the stored items.

After the closed container is used, when the lid is returned to the upper surface of the opening and pressed in the engaging direction, the engaging elastic piece of the lid and the engaging piece of the connecting body are elastically deformed. The engagement protrusion engages with the engagement receiving portion, and the lid is closed. As described above, since the lid can be easily opened and closed with one touch, a closed container excellent in operability can be obtained. Furthermore, since the elastic piece for releasing the engagement between the lid and the connecting body is formed integrally with the connecting body, the number of parts of the closed container can be reduced, and the labor and cost for manufacturing can be reduced.

According to the second aspect of the present invention, an elastic piece capable of opening the lid is integrally protruded from the connecting body to provide the same lid opening and closing means as in the first aspect of the present invention, and to maintain airtightness. Is integrally formed on the inner peripheral wall of the connecting body by insert molding. Therefore, the number of parts of the closed container is reduced, and the labor of assembling is omitted. In addition, since the number of parts is small, formation of a gap at the time of assembly is prevented, and the hermetic elastic body is in close contact between the connecting body and the mouth of the container body, and the upper edge protrudes from the upper end of the opening. By tightly contacting the lid, the airtightness can be maintained satisfactorily.

Further, a jumping part which can automatically flip up the lid may be provided integrally with the hermetic elastic body by utilizing the elastic force of the hermetic elastic body of the second invention. The jump-up portion is formed by projecting a shaft support side of the airtight elastic body between the connecting main body and the lid toward the lid. Then, in a state where the lid is closed, the jumping portion is pressed against the inner surface of the lid, elastically contracts, and urges the lid in the opening direction. Then, when the engagement between the engagement protrusion of the connection main body and the engagement receiving portion of the lid is released, the force that has contracted the jumping part is released, so that the jumping part expands in the restoration direction, and the lid is moved. Jump up in the opening direction. This flip-up automatically opens the lid. By forming the jumping part having excellent operability integrally with the airtight elastic body, it can be formed by a simple manufacturing method, and there is no need to separately use a spring material or the like, and the number of parts of the closed container can be reduced. , Because it saves you the trouble of assembling,
It is also economical.
