Description

[Detailed Description of the Invention] The present invention provides a hermetically sealed container, particularly a container suitable for making preserved foods.

Conventional containers of this type are widely made of ceramic or glass for reasons of hygiene and aesthetics, but the structure of the metal fittings that connect the container and lid tightly is complicated, and the installation process is time-consuming. The cost of the containers was high.

Therefore, the present invention has been able to eliminate this drawback, and the illustrated embodiments of the present invention will be described below.

In the container S of this example shown in FIGS. 1 and 2, 1 is a ceramic body with a flange 1a protruding from an appropriate part of the outer periphery (in the figure, the upper end), and 2 is a silicone resin container on the outer periphery step of the lower surface. This is a lid made of ceramics fitted with a gasket 3, and by attaching the lid 2 to the container body 1, the inside of the container can be sealed via the gasket 3.

Note that a downward protrusion 2C is protruded from the portion of the lid body 2 where the gasket 3 is arranged, thereby pressing the gasket 3 and ensuring close contact with the container body 1.

Further, a vertical plug hole 2a is formed in the center of the lid body 2, and a plug 4 made of silicone resin is fitted into the plug hole 2a to close the plug hole 2a.

Reference numeral 5 denotes a stainless steel leaf spring-like tightening member, which has a curved portion 5C formed in its center, and has locking pieces 5a bent at both ends to lock onto the collar 1a of the vessel body 1. A hook portion 5b is formed in series with the locking portion 5a.

After locking one of the locking pieces 5a to the collar 1a,
As shown by the imaginary line in FIG. 2, the other locking piece 5a is pushed and locked to the flange 1a, thereby ensuring that the lid 2 is in close contact with the container body 1.

In this state, the central curved portion 5C of the tightening member 5 comes into contact with the plug 4 and presses the plug 4 with its spring force.

In order to stabilize the position of the tightening material 5, the tightening material 5 is disposed with a guide groove 2b cut out in the peripheral edge of the lid body 2.

Since this example is configured in this way, the container S can be easily sealed by the fastening member 5.

Since the tightening member 5 is a flexible plate spring, it can be attached and detached very easily, and the tightening member 5 can be easily removed by pushing the hook portion 5b from the bottom to the top.

Further, when it is necessary to sterilize food by boiling for long-term preservation, the food may be boiled, deaerated, and sterilized with the fastening material 5 attached.

At this time, since the plug 4 is pressed by the tightening material 5, the plug 4 will not come off.

When opening the container S which has been sterilized by boiling, the lid 2 can be easily removed by reheating it or by making a hole in the stopper 4 with a needle after removing the tightening material 5.

Therefore, it is preferable to form the bottom of the stopper 4 thin.

Although this example is configured as described above, the present invention is not limited to this.

For example, the shape of the lid and the container body does not matter, and their material may be glass.

Further, the position of the plug hole formed in the lid body is also appropriate, and the shape of the plug fitted into the plug hole is not limited.

Furthermore, the structure and shape of the tightening member are arbitrary, and may be two leaf spring pieces 6 as shown in FIG.

The material of the fastening material is not limited either, and the fastening material 7 may be made of synthetic resin and may have both ends locked to the locking protrusion 1C of the container body 1, as shown in FIG.

In short, the present invention is a ceramic or glass container that can be sealed with an independently formed lid via a seal, and a plug hole is bored in the upper surface of the lid, and the plug hole is filled with a material made of silicone resin or the like. This is an airtight container characterized by fitting a stopper made of a synthetic resin, engaging a tightening material that tightens the container body and the lid, and holding down an iron frame with the tightening material.

Therefore, according to the present invention, it is an airtight container with an extremely simple structure, and if the stopper and fastening material are made of heat-resistant material, it can also be used as a storage container that can be boiled, and the installation work is easy and it can be manufactured at low cost. It can be said to be a practical device suitable for home use.
