Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement in a sealed container that maintains airtightness through the adsorption action of the lid.

(Prior art) Conventionally, this type of sealed container was
The one disclosed in Japanese Patent No. 17262 is publicly known, and this has a structure in which a metal buckle is used to forcibly tighten the glass bottle body and the lid when they are sealed via a gasket. However, such conventional sealed containers have drawbacks such as being difficult to handle and difficult to clean due to their complicated structure, and they also require a large amount of storage space due to the use of special metal buckles. The disadvantage was that it increased costs. Furthermore, since the main body and lid are forcibly tightened through a gasket to maintain airtightness, it is difficult to maintain complete airtightness over a long period of time due to poor tightening or deformation of the gasket material. There was also a drawback.

(Problems to be solved by the invention) The present invention solves these conventional drawbacks, has a simple structure, is extremely easy to handle, has a very low molding cost, and maintains complete airtightness. It was completed with the aim of providing a sealed container that can guarantee the

(Means for Solving the Problems) The present invention provides a sealed container comprising a container body having a wide mouth and a lid body formed to seal the mouth part of the container body through a packing. A ring-shaped inclined part extending upward from the outer peripheral edge is provided on the lower surface of the body, and a cylindrical hanging part having an outer diameter slightly smaller than the inner diameter of the mouth of the container body is provided inside the inclined part, and a lower part of the inclined part has a It is characterized by being equipped with a ring-shaped gasket that slopes outward and downward.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

The drawings show an embodiment of the present invention, in which 1 is a glass container body having a wide mouth 2, and 3 is a lid made of hard synthetic resin.

A ring-shaped inclined part 4 extending upward and inward from the outer periphery is provided on the lower surface of the lid 3, and the ring-shaped inclined part 4 has a width from the outer periphery to the inner diameter of the mouth 2 of the container body 1. It is composed of Further, a cylindrical hanging part 5 having an outer diameter slightly smaller than the inner diameter of the mouth part 2 of the container body is provided inside the inclined part 4, and a cylindrical hanging part 5 is provided at the boundary between the inclined part 4 and the cylindrical hanging part 5. A ring-shaped groove 6 is formed. As shown in FIG. 2, the cylindrical hanging part 5 is formed with sufficient length below the lower surface of the lid 3, so that when the lid 3 is fitted onto the container body 1, the hanging part 5 is Container mouth 2
It is configured to be inserted into the inner surface of the A ring-shaped guide 7 made of soft synthetic resin and having a U-shaped cross section is fitted onto the outer periphery of the lower end of the cylindrical hanging portion 5, but the shape of this guide 7 is limited to that shown in the figure. For example, the lower surface may be a flat plate. Further, it is preferable that the lower end corner portion of the guide 7 be provided with a slight inclination as shown in the figure.

A ring-shaped packing 8 is attached to the lower part of the inclined part 4 and is inclined outwardly and downward while maintaining a gap between the ring-shaped packing 8 and the inclined part 4, and its upper end is fitted into the groove 6. The packing 8 is made of a soft material such as silicone rubber, which has a hardness of 30 to 50 degrees and has sufficient elasticity.

The container body 1 and the lid body 3 are made of glass, ceramic, metal,
Alternatively, it may be made of hard synthetic resin, etc., and combinations thereof can be freely selected.
Furthermore, it is also possible to color it in any color.

(Function) The hermetically sealed container configured in this way can be assembled by placing the lid 3 on the glass container body 1 and pressing lightly from above.
Due to the elasticity of the packing 8, the lid 3 sinks downward and the air inside the container body is pushed out to the outside, and as a result, the pressure inside the container body is reduced from atmospheric pressure. In this case, the lid 3 is reliably positioned within the mouth 2 of the container body 1 by the hanging portion 5 and sinks downward, so that the depressurizing effect of the gasket 8 can be reliably obtained. Therefore, due to this depressurizing action, the container body 1 and the lid 3 are brought into complete contact with each other through the gasket 8, and the interior of the body is completely airtight. On the other hand, in order to remove the lid 3 from the container body 1, the reduced pressure state can be easily released by pushing the lid 3 upward.
Further, even when the degree of decompression is high, the decompressed state can be easily released by pulling a part of the gasket 8.
In this case, it is also preferable to provide a part of the packing 8 with a tensioning tongue (not shown) or the like.

In addition, since the sealed container of the present invention utilizes a depressurizing effect, it does not require any complicated metal fittings as in the past, and has a simple structure that is extremely easy to handle, and the molding cost is also significantly reduced. This is something that can be done cheaply. Furthermore, since it is not forced to tighten as in the conventional case, airtightness can be maintained reliably even when the opening of the container main body is not only circular but also rectangular or other deformed shapes.

(Effects of the invention) As is clear from the above explanation, the present invention has a simple structure, so it is extremely easy to handle, does not cause any failures, and can be mass-produced, which significantly reduces molding costs. It is possible to make it cheaper. Furthermore, if it is made of a transparent material such as glass, the contents can be seen, making it an excellent sealed container for storing hygroscopic materials such as seaweed or salty foods that dislike moisture. is effective.

As described above, the present invention solves the problems of conventional sealed containers and has extremely great practical value.
