Description

Sealing Cover for Containers {VACUUM COVER FOR CONTAINER}

The present invention blocks the storage space of a container such as a dish or a bowl from the outside, by moving in a direction to reduce the volume of the storage space due to its own elastic characteristics to improve the airtightness and exhaust the air in the storage space,

It relates to a closed cover that can delay the food is stored in the storage space is in contact with the air to be destroyed.

In storing foods such as fruits, vegetables, and leftovers, the air inside the container is discharged to delay oxidation by aerobic microorganisms to extend the shelf life of stored foods,

To prevent the smell of food or the smell of other food

Recently, a vacuum container used by evacuating air inside a container beyond a simple sealed container has been in the spotlight.

Also, among the vacuum containers, the type used in the method of discharging the air inside the container using a separate electric pump type vacuum device, such as Ahn Jun-young's Republic of Korea Utility Model Registration No. 0395836 (2005.09.07) `` Vacuum container cover '',

Kim Hyung-jun and one other person registered a Korean Utility Model No. 042438 (2005.11.24), such as Vacuum Packaging Container, which has a kind of exhaust piston like a syringe in the container itself.

However, these types of things have not been commercially successful to replace or encroach on simple sealed containers as a major drawback of complicated use.

Furthermore, although the degree of vacuum inside the container does not reach the technical level of the above two documents using separate vacuum devices, it is possible to discharge the air inside the container to some extent with the main purpose of ease of use, thereby obtaining a food oxidation delay effect.

Choi Duk-hae's Republic of Korea Utility Model Registration No. 367933 (2004.11.05), `` Vacuum Sealed Food Container Cover '', Hanakobi Corporation's Republic of Korea Utility Model Registration No. 0413413 (2006.03.31), `` Valve-operated closed container lid ''. .

The utility model registrations all use valves for intake and exhaust inside the vessel. More specifically, after lifting the valve to open the distribution hole, the air inside the container may be discharged (exhausted) or the air may be sucked (intake) into the container distribution, and the valve may be lowered to close the distribution hole so that air may flow into the container. Do not enter or exit.

However, these utility model registration valves can be lifted by hand from the outside of the container, but can also be raised by an impact inside the container.

In other words, if the container is tilted sideways or upside down, the contents stored in the container (especially the bulky contents, such as fruits) will hit the lower end of the valve, which will inadvertently open the opening and introduce air into the container. The seal is released and the lid (ie the seal cover) is easily removed from the container.

The present invention has been made to solve the above problems,

Opening means including a valve for using the valve for the intake and exhaust inside the container, the valve having a structure that can prevent the release of the container inherently released by opening the valve by accidental external force to open the distribution hole It is an object of the present invention to provide a sealed cover.

In addition, a gasket is used for the coupling part of the container and the sealing cover, that is, the coupling part formed on the inner surface of the container and the lower surface of the rim of the body, and the gasket is used to increase the adhesion (sealing property) as much as possible. Another object of the present invention is to provide an airtight cover for a container having a structure that can be easily separated from the coupling portion in the process of separating the airtight cover from the container.

Another object of the present invention is to provide an airtight cover made of an elastomer such as silicone rubber having excellent heat resistance and no environmental hormone leakage problem.

In addition, the object of the present invention is to provide an airtight cover having excellent economic efficiency by maximizing the sealing property but simplifying the overall configuration.

Protruding portion integral with the main body and protruding from a predetermined portion of the outer surface of the main body,

A circulation hole formed adjacent to the protrusion and penetrating the inner and outer surfaces of the main body,

It includes; opening and closing means including a valve for opening and closing the distribution hole by lifting up and down with the protrusion is inserted.

And the protruding portion is formed integrally with an insertion portion connected to the main body, and a pressing portion integrally formed at an upper end of the insertion portion and having a diameter longer than that of the insertion portion.

The valve has a cover which is formed in the center of the insertion hole in close contact with the outer edge of the insertion portion, the gripping portion formed with a receiving hole for accommodating the outer edge of the pressing portion, and extended to the lower outer edge of the gripping portion to cover the distribution hole Characterized in that it comprises a wealth,

In the outer periphery of the insertion portion of the protruding portion is characterized in that the protrusion is formed in contact with the bottom surface of the receiving hole in the state that the valve is lowered,

In the inner wall forming the insertion hole of the valve is characterized in that the groove is inserted into the projection is formed in the valve lifted state,

The lower edge of the main body is characterized in that the engaging portion is projected to form a gasket for contacting the inner surface of the container to seal the coupling portion,

The coupling part includes a vertical part connected to the main body, and a horizontal part protruding outward from the lower end of the vertical part to support the gasket, and the gasket is disposed between the lower surface of the main body and the upper surface of the horizontal part of the coupling part. The body is characterized in that it consists of a contact portion that is projected to be inclined toward the upper side from the outside of the lower end of the body and thinning toward the end.

The sealing cover according to the present invention having the configuration as described above is made of an elastomer, in particular silicone rubber, there is no environmental hormone problem, and also excellent heat resistance, even in the microwave oven or put hot food assembled into the membrane at all the shape change However, there is no fear of leaking and there is no fear of spillage.

Unless the user artificially lifts the valve, there is an inherent risk that the valve will be lifted by accidental shock and open the distributor.

By providing a gasket having a specific structure, the sealing property of the container and the sealing cover is improved, and the gasket is not easily separated from the sealing cover in the process of attaching or separating the sealing cover from the container.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a perspective view showing an example of a sealing cover according to the present invention, Figure 2 is a cross-sectional view of the sealing cover shown in Figure 1,

3 and 4 are cross-sectional views of the sealing cover according to another example.

In the present invention, the article to be combined with the airtight cover will usually be a bowl or bowl-type container, but the dome-shaped cover shown in FIG. 1 covers a smooth surface (for example, glass panel) provided on a dining table and the like. Since it is possible to form a, in this specification, the term 'sealing cover' is used instead of 'sealing lid' to encompass this concept.

As can be seen in the figure, the sealing cover of the present invention and the elastic body 10,

It comprises a opening and closing means 20 consisting of a protrusion 21, the distribution hole 23 and the valve 25,

The gasket 30 may be further included.

The main body 10 may be divided into a dome shape as shown in FIGS. 1 and 2 and a flat shape as shown in FIGS. 3 and 4 according to its shape.

According to the form of contact with the container 1 as shown in Figure 3 the inner surface of the container 10 inscribed (inscribed) contact the outer surface (inscribed type), as shown in Figure 2 the outer circumference of the cover border on the outer surface of the container (1) can be divided into (circumscribed) types.

In addition, the material of the elastic body 10 may be made of an elastomer having good elasticity without any environmental hormone problem, such as silicone rubber, and may be made of a weak, yet rigid, rigid plastic material.
Here, the elasticity is a concept sufficient if the outside air can be sucked into the storage space (2) by the self-resilience. That is, the main body is contracted by the external force pressed by the user and exhausted to the outside of the storage space, and the external air is introduced into the storage space by the self restoring force of the main body without the action of the external force, and made of a hard plastic material. The body is also weak but elastic.
And the hard plastic body is mainly used to seal the containers to eat and carry frequently, such as cookies or peanuts at home,
As described above, since the valve of the opening and closing means employed by the airtight cover of the present invention does not open due to the impact of the contents (cookies, peanuts, etc.) contained in the storage space,
Even if the container is dropped or shaken during use of the container with the sealed cover attached, the valve is not inadvertently released (separated) from the container due to unintentional sudden on / off action of the valve. There is no fear of being injured by the detached airtight cover.

The main body 10 has elasticity, and presses the main body 10 by hand in a state in which the flow hole 23 is opened by the valve 25 to push the air in the storage space 2 of the container 1 to the outside. When the discharge hole 23 is closed by the valve 25 after the discharge (exhaust), the pressure in the storage space 2 is lowered, so that the main body 10 is firmly coupled to the container 1. When the main body 10 is separated from the container 1, the valve 25 is lifted up to open the distribution hole 23 so that external air flows into the storage space 2 (intake) and then the valve 25 is operated by hand. B. Lift the main body 10 and lift it up easily.

As shown in FIG. 2, an edge of the main body 10 which is in contact with the outer surface of the container 1 is connected to the skirt 11 which is in contact with the outer surface of the container 1, and the separation prevention of the male and female ends coupled to the end of the container 1. The part 13 is formed.

3 and 4, the engaging portion 15 is formed on the lower surface of the edge of the main body 10 which is in contact with the inner surface of the container 1, and the engaging portion 15 has a container ( In contact with the inner surface of 1) is fitted a gasket 30 to increase the sealing.

The coupling portion 15 is a vertical portion 15a integrally connected to the lower surface portion of the main body 10,

It consists of a horizontal portion 15b integral with the vertical portion 15a and protruding from the lower end toward the outside.

At this time, the end of the main body 10 is further protruded outward than the horizontal portion (15b) so as to fully rest on the end of the container (1).

In addition, the gasket 30 includes a body 31 disposed entirely between the lower surface of the main body 10 and the upper surface of the horizontal portion 15b;

Protruding obliquely at an angle toward the top from the outside of the lower end of the body 31 is composed of a contact portion 33 gradually thinning while going to the end.

As such, by lengthening the body 31 of the gasket 30 between the lower surface of the main body 10 and the upper surface of the horizontal portion 15b,

When the air in the storage space 2 of the container 1 is disposed and the main body 10 receives the contracting force, the end of the container 1 and the gasket 30 support the lower surface of the edge of the main body 10 so that Prevents the 10 from bending more than necessary inside the container 1,

When the main body 10 is forcibly separated from the container 1 while the flow hole 23 is not sufficiently opened, the flow range of the gasket 30 is restricted so that the gasket 30 is separated from the coupling part 15. Minimize the risk of

In addition, the contact portion 33 gradually thinner and inclined toward the upper portion from the lower end to the end of the body 31 is in contact with the inner surface of the container 1 in the process of coupling the main body 10 to the container 1. In a state where it descends upward and is fully engaged with the container 1, it is forced to be restored to its original state (that is, to protrude outward) and closely adhered to the inner surface of the container 1 to further enhance the sealing property.

For reference, the main body 10 shown in FIG. 3 is bent at a right angle to the main surface of the valve 25, and the main surface of the main body 10 shown in FIG. 4 is inclined.

The main body 10 of FIG. 3 is for minimizing the exposure of the valve 25 in view of appearance, and the main body 10 of FIG. 4 is for facilitating a user to hold the valve 25.

The opening and closing means 20 includes a protrusion 21, a distribution hole 23, and a valve 25. Hereinafter, the valve 25 is lowered to open and close with reference to FIG. 3, which shows a state in which the flow hole 23 is closed, and FIG. 4, which shows a state in which the valve 25 is lifted and the flow hole 23 is opened. The means 20 will be described.

The protrusion 21 is formed integrally with the main body 10 and protrudes from the outer surface of the main body 10, and is usually formed at the center of the main body 10, but may be formed outside the center.

And the protrusion 21 is an inserting portion (21a) connected to the main body 10,

It consists of a pressing part (21b) formed at the top and integral with the insertion portion (21a).

The pressing portion 21b has a larger diameter than the protrusion 21.

The distribution hole 23 is formed through the inner and outer parts of the main body 10 at the main surface of the protrusion 21 to be a distribution path of air, and is provided as necessary. Usually four are formed radially.

The valve 25 is a gripping portion 25d for the user to hold,

It consists of a cover part 25e which is extended and formed in the lower end of the holding part 25d so that the flow hole 23 may be opened and closed.

The cover portion 25e gradually becomes thinner toward the end portion (outer side).

A receiving hole 25b is formed at the center of the gripping portion 25d to accommodate the pressing portion 21b of the protruding portion 21,

An insertion hole 25a is formed at a lower portion thereof in communication with the accommodation hole 25b and into which the insertion portion 21a of the protrusion 21 is inserted.

The inner diameter of the insertion hole (25a) has a length corresponding to the diameter of the insertion portion (21a) in close contact with the outer edge of the insertion portion (21a) so that air does not flow into / out through the insertion hole (25a).

An annular protrusion 21c is formed at the outer edge of the insertion portion 21a, and a recess 25c is formed at the inner edge (inner wall) of the insertion hole 25a to which the protrusion 21c is male and female.

The protrusion 21c is inserted into the groove 25c in the elevated state to prevent the valve 25 from descending due to its own weight or weak external force,

In the lowered state, the lid contacts the bottom surface of the accommodating hole 25b so that the lid is strongly adhered to the outer surface of the main body 10 around the distribution hole 23, and the valve 25 is in the inclined state of the container 1. ) To prevent lifting.
