造を設けることが提案されている。Conventionally, there are cases where various foods such as fruits and vegetables, and other fish meat are stored in a container made of expanded synthetic resin, for example, expanded polystyrene, while maintaining an airtight state. At this time, the container body made of expanded polystyrene is closed with a plate-shaped or box-shaped lid body also made of expanded polystyrene or made of another material, and an adhesive tape or the like is attached to the periphery thereof for use.
This is because when the container body made of expanded polystyrene is simply closed with such a lid, the airtightness of the inside is not sufficient, and furthermore, in the course of use, the engagement defect such as the lid detaching from the container body is prevented. This is because. However, the adhesive work for airtightly engaging the container body and the lid with the adhesive tape or the like is troublesome, which is a major obstacle after packing. In order to solve such incomplete engagement between the container body and the lid and insufficient airtightness, the abutting portions of the lid b are fitted to the container body a as shown in FIG. It has been proposed to provide a fitting structure composed of a convex portion c and a concave portion d so that the state can be maintained.

As with the tape sticking, the work of sticking the adhesive tape is required. Furthermore, since the fitting state in which the airtightness of the container body a and the lid b is maintained is not strong, it is easy for cold air in the container to escape,
The outside air may affect the inside.

概念である。The details of the airtight container according to the present invention will be described with reference to the accompanying drawings. In the figure, 1 is a container body made of expanded synthetic resin, and 2 is a lid body made of expanded synthetic resin. As the expanded synthetic resin body, various expanded synthetic resin bodies such as expanded polystyrene, expanded polyethylene, expanded polyurethane are used.
As shown in the figure, the container body 1 has a general box shape, and the lid body 2 has a plate shape that covers the rim of the container body 1 or a bottomed and shallow box shape. . However, adoption of various shapes for the container body 1 and the lid body 2 is not hindered at all. Such a container body 1
One and the other of the fitting structures are provided at the contacting portion of the lid body 2, that is, at the rim of the container body 1 and the peripheral edge of the lid body 2.
In this fitting structure, the ridges 3 of the container body 1 are provided along the entire circumference of the rim of the container body 1 by opening both sides of the rim of the container body 1 toward the inner side or the outer side of the rim as illustrated. A ridge 4 is provided on the outer or inner side of the rim of the lid 2 that comes into contact with the ridge 4, and the side surface of the ridge 3 contacts the side of the ridge 3 on the container body 1 side when the lid is closed. . Then, on the contact surface of the ridge 3 on the container body 1 side, a convex portion 7 is formed on the upper portion and a concave portion 8 is formed on the lower portion continuously or intermittently over the entire circumference of the container body and the lid body, Similarly, on the contact surface of the protrusion 4 on the lid body 2 side, a concave portion that engages with the convex portion 7 on the container body 1 side continuously or intermittently over the entire circumference of the container body and the lid body. 8, a convex portion 7 that engages with the concave portion 8 on the container body 1 side is formed in the lower portion, and airtight engaging portions 5 and 6 that engage with each other are provided. Details of the ridges 3 and 4 provided with the airtight engagement portions 5 and 6 are shown in FIGS. 2 to 5. In FIG. 2, the protrusion 3 on the container body 1 side is provided on the inner side of the mouth edge thereof, and the protrusion 4 on the lid 2 side is provided on the outer side of the peripheral edge thereof. The abutting surface of the is formed by continuously forming a convex portion 7 on the upper side in the longitudinal direction and a concave portion 8 on the lower portion, and a concave portion for receiving the convex portion 7 and the concave portion 8 on the protrusion 4 on the lid 2 side. 8 and the convex portion 7 are formed continuously in the upper and lower portions.
Reference numeral 9 in the figure indicates that the compressed air accumulated inside the container body 1 generated when the lid body 2 is closed on the container body 1 escapes to the outside in the width direction of the ridge 3 on the container body 1 side. It is an air escape groove provided from the surface to the contact surface with the protrusion 4 on the lid 2 side. In FIG. 3, the ridge 3 is provided on the outer side of the mouth edge of the container body 1, and the ridge 4 is provided on the inner side of the peripheral edge of the lid body 2. Similar to the one shown in FIG. 2, the airtight engagement portions 5 and 6 are formed. Next, in FIG. 4, similar to that shown in FIG. 2, protrusions 3 and 4 are provided on the container body 1 side toward the inside and on the lid body 2 side toward the outside, respectively. On the contact surface of the ridge 3 on the side, the concave portion 8 and the convex portion 7 are provided from above, and further on the lower portion thereof, the concave portion 8 is further provided. 7, a concave portion 8 and a convex portion 7 provided below the concave portion 7 are shown. In addition, in FIG. 5, the convex portion 7 and the concave portion 8 are formed from the upper side on the inner surface side of the upper portion of the rim of the container body 1, and the ridge 3 is formed.
It is shown that the ridge 4 is provided on the lid body 2 side so as to enter the inside of the container body 1. Both ridges referred to in the present invention 3,
Opening both sides of 4 is a concept that includes such aspects.

To facilitate elastic deformation of the container body 1 or lid 2
At the base end side on the contact surface side of the projections 3 and 4 provided on the corresponding to the convex portion 7 formed on the contact surface, continuously or intermittently over the entire circumference of the container body and the lid. It is a groove with an opening width provided in the. In order to facilitate elastic deformation of the one of the protrusions 3 and 4, a notched groove having no opening width (not shown) may be provided instead of the concave groove having the opening width shown.

In this way, the two ridges 3 and 4 provided on the container body 1 and the lid 2 are the inner ridges 3 and 4 on the inner side, and the outer ridges 3 and 4 on the outer side. Groove 1 provided at the base end of the ridges 3 and 4 of
The two fit together while being deformed by 0 or a notch, and then the airtight engaging portions 5 and 6 of the both engage with each other to form a closed lid, and the lid 2 is easily separated from the container body 1 after the lid is closed. The airtightness between the inside and the outside of the container is maintained well.

のである。[Effects of the Invention] In the airtight container according to the present invention as described above, when the lid is closed, the one in which both the protrusions provided on the container body and the lid are provided on the inner side of the container, Also, the one provided nearer to the outside is one that is deformed by utilizing the elasticity of each material on the outside and the groove or notch provided at the base end of one of the projections to close the lid. After the lid is closed, the airtight engaging portions provided on the abutting surfaces of the two protrusions engage with each other, so that the airtight state inside can be favorably maintained. Even when the container main body and the lid are formed in a tight fitting relationship, both of the protrusions are free ends, and both sides of them are in the open state. The accumulated air can be effectively discharged, and the lid closing work can be performed very smoothly. Furthermore, there is no possibility that the lid will float after the lid is closed. Further, the cold air in the container does not easily escape and the outside air does not affect the inside.
