Description

Anti-oxidation vacuum container {VACUUM CONTAINER}

The present invention relates to an anti-oxidation vacuum container, and more particularly, when the lid is closed, the air inside the body is automatically exhausted, so that the inside of the body can be easily and simply vacuumed so that the contents can be stored for a longer time without deterioration. And, in particular, it relates to an anti-oxidation vacuum container that can easily release the vacuum state inside the main body while preventing oxidation of contents such as seasonings, etc.

A vacuum container is widely used as a container for storing various food ingredients, food, or seasonings such as seasonings.

A vacuum container is to create a vacuum inside the container to prevent the contents from being deteriorated, and it is convenient because the storage period of the contents can be extended longer than that of a general container.

Such a vacuum container is equipped with a separate valve on the lid for evacuating air and maintaining the vacuum.

However, as can be seen in Utility Model Registration No. 20-0311423, etc., the conventional vacuum container has the disadvantage that the inside of the container cannot be completely vacuumed structurally.

In other words, although it is a vacuum container, the effect of extending the retention period of the contents through vacuum is satisfactory because it does not completely vacuum the inside of the container, but only removes some of the air inside the container to block the inflow of external air. There is an inconspicuous problem.

In particular, in the case of contents that are stored for a long time, such as seasonings, etc., deterioration such as oxidation often occurs due to prolonged exposure to the residual air inside the container.

As an alternative to this, there is a container that uses a separate air pump in addition to the valve on the lid to forcibly exhaust the air inside the container to create a vacuum state, but this is inconvenient to use and is relatively expensive and large container, so it can be used for seasonings, etc. Not suitable for storage.

Accordingly, the present invention has been devised to solve the above problems,

When the lid is closed using a check valve, it is automatically exhausted to create and maintain a vacuum state. In particular, it keeps the inside of the container in a complete vacuum state to prevent oxidation of contents such as seasonings, etc. An object of the present invention is to provide an anti-oxidation vacuum container capable of easily releasing the lid to easily open the lid.

In the drawings of the present specification, the air flow hole is dualized into the exhaust port 11 provided in the center of the lid (C) and the air supply port 12 formed on both sides of the exhaust port 11, the first check valve 13 ) and the second check valve 13 respectively open and close the exhaust port 11 and the air supply port 12, so that each hole performs the exhaust and air supply functions opposite to each other. However, the present invention is not limited thereto.

For example, a check valve may be mounted in a single hole as an air flow hole so that exhaust to the outside of the body and air to the inside of the body are simultaneously made, and the interpretation of the rights of the present invention should not be limited thereto.

Specifically, the lid (C) is coupled to the bottom plate 10 provided with the air flow hole (the exhaust port 11 and the supply port 12), the bottom plate 10, the upper part, and the elevating part 21 and The upper plate portion 20 having the protruding hole 22, and the lifting plate 30 having the check valve (second check valve 31) coupled to the lift portion 21 to elevate, and the pulling member 50 is coupled to the lifting plate 30 so as to be exposed to the upper portion of the protruding hole 22 .

The bottom plate 10 is provided with a side wall portion 14 protruding upwardly inside the rim to form a rim mounting portion by fitting with the outer wall portion 24 of the elevating plate 30 to be described later, and the rim mounting portion to the sealing ring 40 is coupled to the mounted.

In addition, the bottom plate 10 is provided with a protruding portion 15, a portion of which the exhaust port 11 is provided, protruding upward, for mounting of the first check valve 13 to the protruding portion 15. A first fitting hole 16 is provided.

The first check valve 13 restricts the flow of air in only one direction. The first opening/closing membrane 13a is formed in a dome shape to cover the exhaust port 11 and the rear end of the first opening/closing membrane 13a. It is connected to the side and consists of a first coupling protrusion 13b fitted into the first fitting hole 16, and the second check valve 31 also has a similar shape of a second opening/closing membrane 31a and a second coupling protrusion ( 31b).

The first and second check valves 13 and 31 (especially the opening/closing membranes 13a and 31a) are made of a soft material having a predetermined elastic force, such as rubber or silicone, and based on the bottom plate 10, Due to the pressure change in the upper and lower spaces, the opening/closing membranes 13a and 31a are lifted to open the exhaust port 11 and the supply port 12, or the opening/closing membranes 13a and 31a are restored to their original state while the bottom plate ( 10) to close the exhaust port 11 and the air supply port 12.

On the other hand, in the case of the air supply port 12, the second check valve 31 is forcibly opened by the pulling member 50 to supply air to the storage unit Ba, but when the lid C is actually closed, the first check valve 31 is forcibly opened. As shown in (13), an exhaust function may occur due to the opening of the opening/closing membrane 31a,

Accordingly, the exhaust hole 11 and the first check valve 13 are omitted, and the air flow hole in the form of a single hole composed only of the supply port 12 can be formed as described above.

Then, the upper plate part 20 has an outer wall part 24 fitted to the side wall part 14 inside the rim to protrude downward to form a lifting part 21 of the upper part of the bottom plate 10, and the central part circumferential direction The inner wall portion 23 forming the protruding and protruding hole 22 is provided to protrude downward.

The top plate 20 is mounted with a sealing ring 40 fitted to the edge mounting part formed by coupling with the bottom plate 10 .

In addition, the lifting plate 30 is a member in the form of a wing part 32 protruding in the circumferential direction of the body part fitted into the protrusion hole 22 and connected, and the pulling member 50 is fitted and coupled to the body part. The pulling member 50 is exposed through the protruding hole 22 .

The lifting plate 30 has a receiving portion having an open lower surface, the protruding portion 15 is coupled to be accommodated inside the body portion, and an exhaust hole 34 through which the exhaust port 11 communicates with the outside of the lid (C). ) is perforated in the circumferential direction of the pulling member 50 .

And the wing part 32 of the lifting plate 30 is provided with a second fitting hole 33 at a position corresponding to the air supply port 12, and as the second check valve 31 is coupled, the second opening The closing film 31a covers the air inlet 12 .

In addition, in order for the lifting plate 30 to be coupled to the inner circumferential surface of the protruding hole 22, that is, the inner surface of the inner wall portion 23, a hook protrusion 35 protrudes from the circumferential surface of the body portion, and the inner wall portion ( 23) is provided with a guide groove 23a on the inner surface of which the hook projection 35 is engaged, but is formed at a height higher than the hook projection 35 to guide the lifting and lowering of the hook projection 35 .

On the other hand, the second check valve 31 is molded so that the second coupling protrusion 31b is coupled to the second fitting hole 33 in a locking structure as shown in the figure, in this case, the end of the second coupling protrusion 31b is not cut. The second coupling protrusion 31b functions as an elastic body by forming it long so as to be in contact with the upper plate portion 20 without it, and this will be described later.

The pulling member 50 has a holding portion protruding from both sides of the upper end, and is fitted to the lifting plate 30, so that when the pulling member 50 is pulled upward, the lifting plate 30 rises and the second The closing membrane 31a is lifted to open the air inlet 12 .

Meanwhile, the upper plate portion 20 includes a handle 25 connected to pass through the upper portion of the pulling member 50 .

The meaning that the handle 25 is connected to pass through the upper portion of the pulling member 50 means that the handle 25 is formed on the upper portion of the pulling member 50 in the same direction as the gripping part, as shown in the figure. Both ends of (25) are not limited to the form connected to the upper edge of the upper plate (20).

At this time, the handle 25 includes a guide hole (25a) formed by opening the lower surface,

The pulling member 50 includes a guide protrusion 51 protruding upward to fit into the guide hole 25a.

The guide hole 25a is formed at a predetermined height vertically to guide the elevation of the guide protrusion 51 .

When explaining the vacuum generation and vacuum release operation using the opening and closing of the lid (C),

First, when the lid (C) is inserted and sealed into the storage unit (Ba), the sealing ring 40 makes the inside of the body (B) in an airtight state while in contact with the inner surface of the body (B), and the user Holds the lid (C) and closes it by pushing it all the way (to the top level of the contents stored in the body (B)).

When the lid (C) is inserted into the body (B) and closed in this way, the first opening/closing membrane (13a) of the first check valve (13) is closed due to an increase in pressure due to a decrease in the internal volume of the body (B). The exhaust port 11 is opened while being lifted, and the air inside the body B passes through the exhaust port 11 and is discharged to the outside of the lid C through the exhaust hole 34 .

At this time, as the second check valve 31 is elastically supported downward due to the second coupling protrusion 31b, the lifting plate 30 does not rise, so that the second opening/closing membrane 31a is not lifted. The closed condition of the instrument 12 is maintained.

Of course, even if the second opening/closing membrane 31a is lifted and opened by itself due to an increase in pressure inside the body (B), it returns to its original state by the elastic force of the material itself after exhaust is completed like the first opening/closing membrane 13a, and sealed is maintained.

Therefore, when the lid (C) is closed to the end, all the air inside the body (B) is discharged and the exhaust port (11) is closed by the return of the first opening/closing membrane (13a) to its original state, and the inflow of external air is blocked and the main body ( B) The inside becomes a vacuum state, which prevents deterioration of the contents, especially oxidation, in storage.

And when the lid (C) is opened, when the user pulls the gripping part of the pulling member 50 with a finger in the form of holding the handle 25, as the lifting plate 30 rises, the second check valve ( 31) is lifted, the air supply port 12 is opened, and external air is introduced into the body (B) through the opened air supply port (12), the vacuum state inside the body (B) is released, and the lid (C) You can open it easily by holding it as it is.

At this time, elastic force is accumulated due to compression or shape deformation of the second engaging protrusion 31b, and therefore, when the finger is released from the gripping part after the lid C is opened, the elastic force of the second engaging protrusion 31b is applied to the elevating plate ( 30) and the pulling member 50 is automatically lowered and returned to the original position.

In this case, although not shown in the drawings, a separate elastic body (for example, a compression spring around the lifting plate 30) may be additionally mounted separately from the second coupling protrusion 31b.

On the other hand, in the drawings of the present specification, the completely detachable lid (C) is representatively shown with respect to the main body (B), but the introduction of the hinged opening and closing type lid (C) is also possible. (C) may additionally adopt a structure in which the body (B) is lifted up and down in the storage unit (Ba).

The present invention of this configuration makes the inside of the main body (B) in a vacuum state to extend the storage period by maximally slowing the deterioration, especially the oxidation, of the contents being stored, and only opening and closing the lid (C) without a separate device or additional operation. (B) It is convenient to use because the vacuum is generated and the vacuum is released, and in particular, there is an advantage that the opening of the lid (C) is made very easily.

In the above description of the present invention, with reference to the accompanying drawings, the oxidation prevention vacuum container has been mainly described, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and such modifications, changes and substitutions are within the scope of the present invention. should be interpreted as belonging to
