Description

[Detailed description of the invention] (Field of industrial application) This invention is a vacuum system suitable for storing hygroscopic materials such as seaweed or contents that are extremely sensitive to moisture such as salty foods. This invention relates to improvements in type sealed containers.

(Prior art) Conventionally, this type of sealed container was
The one disclosed in Japanese Patent No. 17262 is 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 complex 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 vacuum-type 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 cylindrical guide part having an outer diameter slightly smaller than the inner diameter of the mouth of the container body is provided on the lower surface of the body, and a ring-shaped packing that slopes outward and downward is fitted to the outer periphery of the guide part, and The wall is provided with a plurality of locking protrusions arranged at equal intervals, and when the lid body is pressed and fitted to the container body, a part of the ring-shaped gasket is placed against the locking protrusions to secure the container. It is characterized by releasing the air inside.

(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 container body made of glass or plastic having a wide mouth 2, and 3 is a lid made of plastic. A cylindrical guide portion 4 having an outer diameter slightly smaller than the inner diameter of the opening of the container body 1 is provided at the center of the lower surface of the lid body 3.
A tapered guide ring 5 is fitted to the lower end of the container to facilitate insertion into the mouth 2 of the container body 1. A ring-shaped packing 6, which is made of a sufficiently elastic material with a hardness of 30 to 50 degrees, such as silicone rubber, is fitted onto the outer periphery of the guide portion 4. ing. Further, a small annular projection 7 is provided on the outer periphery of the upper part of the ring-shaped packing 6.

On the other hand, as shown in FIG. 3, two gasket locking protrusions 8 are provided at equal intervals on the outer peripheral wall of the container opening 2. As shown in FIG. Although the number of the gasket locking protrusions 8 is two in the embodiment, it is also possible to protrude and arrange more protrusions at equal intervals. Further, as shown in FIG. 4, the seal locking projection 8 is preferably provided with a raised convex portion 9 at its tip. The locking protrusion 8 may be integrally molded with the container body 1 as in the embodiment, or the locking protrusion 8 alone may be added in a later process, or the annular member provided with the locking protrusion 8 may be attached to the container mouth portion. It may be provided by any method, such as by fitting it in.

(Function) In the vacuum sealed container of the present invention configured as described above, when the cylindrical guide portion 4 on the lower surface of the lid 3 is inserted into the opening 2 of the container body 1 and the lid 3 is pushed down, First, a ring-shaped gasket 6 attached to the outer periphery of the guide part 4 and inclined outwardly downward comes into contact with the top surface of the mouth part 2, and when the lid body 3 is further pushed down, the inside of the container is gradually pressurized. When the lid body 3 is pushed down by a certain distance,
As shown in FIG. 4, when the lower tip of the ring-shaped packing 6 hits the protrusion 8 provided on the container mouth 2, a part of the packing 6 is slightly deformed, and the close contact between the ring-shaped packing 6 and the top surface of the opening is broken. It is released and the pressurized air inside the container is released to the outside. In this case, the protrusion 9 at the tip of the protrusion 8 completely prevents the seal 6 from sliding outward and deforms the seal 6, thereby reliably releasing the close contact with the top surface of the mouth. Furthermore, since the air inside the container is released only at the protrusion 8, high-pressure internal air is momentarily released outside through a small gap, producing the sound of air escaping. This air release sound allows the user of the container to confirm that the air inside the container is being released by pressing the lid. After that, when the lid 3 is stopped being pressed down, the elasticity of the ring-shaped gasket 6 pushes the lid 3 upward, but during this process, the gasket 6 remains in close contact with the top surface of the container opening 2. Therefore, as shown in FIG. 2, when the lid is closed, the inside of the container is maintained at a reduced pressure by the amount of change in capacity, and is completely sealed. Therefore, in this state, there is no risk of inhaling moisture from the atmosphere.
The contents can be stored in a dry state for a long period of time.

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, and even if the degree of decompression is high, part of the gasket 6 can be removed. You can easily release the reduced pressure state by pulling it. In this case, Patsukin 6
It is also preferable to provide a tensioning tongue piece (not shown) or the like in a part of the holder.

(Effects of the invention) As is clear from the above explanation, the present invention allows the container to maintain a sealed state while reducing the pressure inside the container by simply pushing the lid, so there is no fear of outside air entering. , foodstuffs and the like can be stored in a dry state for a long period of time. In particular, if the container body is made of a transparent material such as glass, the contents can be seen, making it very effective as a sealed container for storing foods and the like. Furthermore, since it has a simple structure, it is extremely easy to handle, does not cause any breakdowns, and can be mass-produced, making it possible to significantly reduce molding costs.

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