Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic air opening /

The present invention relates to a container for storing a large amount of liquor or beverage, and more particularly, to an automatic liquor and beverage container which is capable of discharging the contents while automatically introducing outside air into the container, More particularly, the present invention relates to an air opening and closing apparatus, and more particularly, to an air opening and closing apparatus for manually operating a separate air opening and closing means such as an air circulation stopper when drinking the contents of beer or other liquefied beverage or drinking water and bottled water filled in a large- The contents of the storage container can be discharged smoothly by automatically introducing the outside air into the closed space of the storage container even if the operation of the contents discharging means is performed only without operation of the discharge means, Air is automatically sealed and the contents remaining in the storage container are safely sealed The present invention relates to an automatic air opening and closing apparatus for a mainstream and beverage container.

As you can see, camping products are booming as camping culture is spreading rapidly in recent years. The sales of tents, outdoor goods, and even SUVs are on the rise. For example, bottled water is also available in 3 to 5 liters of PET bottles. Especially, beer, like pitche or keg (usually 5 liters) And so on.

However, the problem is that when drinking a liquor or a beverage filled in a large-capacity storage container such as a kane can in the field, it is different from a case in which a taste of the contents contained in a small- . This is because, in case of large capacity, bottled water or beer can not be opened at once and can not be drunk at once, and the lid is opened and closed with little difference every time it is used.

As we all know, in the case of various alcoholic beverages and beverages, the characteristic flavor of the contents is lost when the fragrance or the carbonic acid disappears, and in the case of bottled water, the bacteria grow and multiply when stored for a long time. Especially in the case of cola, beer or soju containing carbonic acid. Therefore, in the case of beer or soju filled in an airtight container, it is necessary to open the lid as quickly as possible so as not to leave it in a short time, or to drank it all at once, or to reduce the taste and flavor of the contents by closing the lid quickly, There is no other way.

However, in the case of a storage container filled with a large amount of contents, once the lid is opened, the remaining amount of the remaining contents of the lid must be left to be reloaded. This time, too, the fragrance and taste remaining in the contents of the storage container were lost over time, and it was hard to prevent the cause of the contents getting rancid and eventually discarded.

For reference, as shown in numerous references such as Utility Model Registration No. 20-0292087 (beer can) and No. 20-0280803 (opening device for beer can), an example of a beverage container developed by most companies In the case of a large-capacity beer can, the user manually opens the air opening / closing means to allow air to flow into the beer can as a storage container. In order to drink the contents, a drain cock The air circulation stopper, which is a separate air opening / closing means formed on one side of the upper side of the storage container, must be manually operated while being opened. The 5 liter capacity keg which is widely used for home use now, or the large volume of bottled water container is composed of this type of storage container.

As a typical example of such a large-sized liquor and beverage storage container, Germany uses a large number of storage containers such as a 5-liter kettle because we drink beer as if drinking barley tea. However, apart from the drain cock serving as the content discharging means, the air circulation stopper of the air inflow hole formed by the air opening / closing means on the upper side of the storage container is inevitably introduced to the inside of the storage container for continuously communicating air while drinking beer It is common to open and just open and drink.

As a result, the carbonic acid contained in the contents of the inside of the storage container is volatilized through the open air inflow hole of the storage container, and the unique taste and aroma disappear, which causes rancidity. This experience is often felt when we drink 1.5 liters of high-volume Pitzer beer, and the world such as Europe, Japan, and the United States is using the large-capacity storage container of such a discharge method unavoidably, and it is very troublesome.

On the other hand, while we are thinking casually, the main entrance to drinking liquor and drinking water is large in order to drink liquor and beverage, because a certain part of the outflow inlet is liquid and the other part of the outflow is crossed. So that the contents of the container can be discharged smoothly even a little.

At present, the inner diameter of shochu bottle or cola bottle is usually about 22 to 24 mm, which is designed to maximize the balance between the amount of liquid leakage and the amount of air introduced. In this case, It is difficult to prevent excessive inflow of air. Then, after closing the cap and drinking again, the air and the contents in the container react chemically to change the taste. As the unnecessary excess air is introduced, various kinds of liquor as well as the living water There is also a growing likelihood of causing hygienic problems.

As a result, mass storage containers for liquor and beverage basically prevent the internal gas from communicating with the outside air. However, in order to solve such a problem, in addition to the operation of opening the drain cock which is a means for discharging the contents, the ordinary air circulation stopper corresponding to the separate air opening and closing means is inevitably opened. Especially, It is difficult for the user to know the absolute value of the air flowing into the storage container and also the adjustment itself is difficult and if the user forgets to close the air circulation stopper appropriately or opens it for a long time, There are inconveniences and problems.

Accordingly, the present invention has a problem in that the taste and flavor of the contents are damaged due to the ingestion of excessive air generated during long-term storage, which is a structural problem of the air (oxygen) inflow device installed in the conventional closed- When the contents of beer or other liquor, beverage and mineral water filled in a large-capacity sealed storage container are to be consumed, a separate air opening and closing means such as an air circulation stopper is manually operated The contents of the storage container can be smoothly discharged while the outside air is automatically introduced into the closed space of the storage container by only opening and closing operation of the contents discharging means such as a drain cock, As the air entering the storage vessel from the outside is sealed, the contents remaining in the storage vessel And to provide an automatic air opening and closing device for a mainstream and beverage container that can be safely and hermetically protected.

That is, the present invention relates to an air automatic opening / closing valve (not shown) provided in a storage container without the hassle of manually opening the air opening / closing means when the user wishes to drink beer And the Auto Air Open & Close Valve System, which can automatically stop the inflow of oxygen into the storage container when not in use, can be operated automatically. The automatic air opening and closing device of the container provides a taste of the contents due to the ingestion of excessive air generated during long-term storage, which is a structural problem of the air (oxygen) inflow device installed in a conventional sealed storage container It is aimed to be able to overcome the problem of fragrance being damaged structurally.

The automatic air opening / closing apparatus of the mainstream and beverage container of the present invention developed to achieve the above object is installed in a storage container filled with a large amount of liquor or beverage, The automatic air opening / closing device of the mainstream and beverage containers according to the present invention includes a plurality of air open / close valves disposed at the center of the air automatic opening / closing valve, A valve stopper having an inlet hole formed therein and a support fixing protrusion projecting upwardly from the center are fitted into the center of the valve stopper so as to form a central inclined protrusion with a curved protrusion at the center lower side, A valve silicone plug for sealing the air inlet hole of the capper, A plurality of air inflow holes are formed on the outer surface of the storage container, the air inflow hole being opened according to an opening operation of the valve silicone cap according to an internal pressure change of the valve cap, And a valve lower housing having an air inlet hole formed at a lower center of a valve operation space portion which is located inside the storage container and forms a certain space around the valve stopper.

Further, the air automatic opening / closing valve is provided on the upper side, the lower side, or one side of the storage container filled with a large amount of mainstream or beverage, and constitutes the air automatic opening / closing valve by only opening / closing operation of a separate contents discharging means provided below the storage container A flexible silicone valve for automatically opening the air inlet hole of the valve cap which is normally closed in accordance with the pressure change in the reservoir and allowing the outside air to flow through the valve upper housing and the valve cap housing, And the air is introduced into the storage container through the air inlet holes and the air inlet and outlet holes, and is discharged through the opened contents opening and closing means.

Particularly, in order to ensure that the normally closed operation of the valve stopper through which the air inlet hole is penetrated can be reliably maintained, the valve seal cap constituting the air automatic opening / closing valve is extended and protruded in a side- And a separate valve housing cover is disposed above the valve upper housing so as to inhibit the inflow of foreign matter and the outflow of contents from the storage container, both in storage and in use, if necessary, And an air inflow hole is formed so that the outside air can be allowed to enter and exit even in the state of being coupled with the air inlet hole.

Thus, the Auto Air Open & Close valve system is implemented so that a certain amount of outside air is automatically introduced into the storage container and the contents are discharged by simply opening and closing the normal contents discharging means such as the drain cock or the drain bowl. The automatic air opening and closing apparatus of the mainstream and beverage containers according to the present invention, to which the automatic air opening / closing valve is applied, has a problem in that when the contents are used in a conventional closed type large capacity mainstream and beverage container, The external air is automatically introduced into the closed space of the storage container by the opening operation of the contents discharging means and the automatic opening operation of the contents discharging means is performed without any troublesome opening and closing operation of the air circulation stopper, The contents can be smoothly discharged, while the discharging operation of the contents is stopped According to the operation principle of the air automatic opening / closing valve, the air introduced into the storage container from outside is automatically blocked, and the contents remaining in the sealed storage container can be safely sealed and protected. It is possible to fundamentally solve the structural problem of forgetting to close the stopper, which is an air opening / closing means, or to leave the remaining contents naturally if it is opened for a long time. In other words, the present invention can provide an air inlet (oxygen) inflow device which is installed in a conventional sealed large-capacity storage container (for example, a keg cans and a fitting or various large-capacity carbonated beverage containers) It is expected that the contents stored in a large capacity storage container can be stored and stored conveniently and safely by solving the problem that the taste and flavor of the contents are damaged due to the souring of the contents that may occur in the storage container.

1 and 2 show a valve housing cover and an upper valve housing constituting an air automatic opening and shutting valve applied to the automatic air opening and closing apparatus of the mainstream and beverage container of the present invention. In order to prevent entry of foreign air into the valve housing cover and the valve upper housing, When the silicone plug is coupled and the valve housing lid is separated from the valve housing lid (which can be used without opening if necessary), external air is introduced into the reservoir through the air inlet hole formed in the valve upper housing and valve lid The principle of enlargement of the part of the air automatic opening / closing valve for automatic inflow.

The air automatic opening / closing valve of FIG. The air is automatically shut off while the air is kept in a hermetically closed state while external air is introduced into the valve upper housing (Including the valve silicone plug in some cases) and the valve plug, and the valve opening of the valve cap is opened and the air is automatically introduced into the container through the air inlet and outlet of the valve lower housing The contents of the storage container are discharged to the outside through the opened contents draining means An operation principle in which an automatic opening and closing valve is installed above the storage container.
FIG. 5 is a side view of a large capacity beer can be applied to an automatic air opening and closing apparatus of a mainstream and beverage container according to the present invention. Drain cocks may be applied, but drain holes may be used in some cases).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements throughout.

The accompanying drawings illustrate embodiments of the present invention in which, in a storage container filled with a large amount of liquor or beverage, the outside air is automatically introduced into the storage container by simply operating the contents discharging means such as a drain cock, The present invention is not limited to the specific embodiments in which the principles of implementation of the automatic air opening and closing apparatus of the mainstream and beverage containers constituting the present invention can be more easily understood, It should be understood that the present invention is not limited to the above embodiments. As a preferred embodiment of the storage container to which the air automatic opening and closing valve according to the present invention is applied, a drain cock is shown as a contents discharging means while explaining a kane cans of a large capacity beer as a preferred embodiment. However, And means for discharging the contents of the structure may be applied.

The automatic air opening and closing apparatus of the mainstream and carbonated beverage container of the present invention basically comprises a separate air opening and closing means, such as an air opening and closing device, for airing beer or other liquefied beverage or drinking water filled in a large- The contents are discharged to the contents discharging means 80 (80) by the pressure change with respect to the contents inside the storage container (70) only by operating the contents discharging means (80) such as a drain cock The air is automatically introduced into the internal sealed space of the storage container 70 through the operating system of the air automatic opening / closing valve 10, in which air from outside is installed above the storage container 70, So that the contents 90 of the storage container 70 can be smoothly discharged together with the inflow of outside air. On the other hand, when the discharging operation of the contents 90 is stopped, The air automatically flows into the storage container 70 from the storage container 70 so that the contents 90 remaining in the storage container can be safely and hermetically sealed, It is preferable that the container 90 is installed above the storage container 70 in which the contents 90 are filled.

That is, according to the present invention, the contents 90 are installed in a storage container filled with a large amount of liquor or beverage, and automatically open to the inside of the storage container 70 while automatically opening the inside of the storage container 70, The automatic air opening and closing apparatus of the mainstream and beverage containers is constructed by applying the air automatic opening and closing valve 10 operated to discharge the air, The valve cap support 20 having the ball 22 formed therein and the support fixing protrusion 32 protruding toward the center upward are fitted into the center of the valve cap support 20, A valve silicone cap 30 is formed to seal the air inlet hole 22 of the valve cap support 20 so as to prevent the introduction of outside air.

The storage container 70 is opened around the valve cap support 20 in which the air inflow hole 22 is opened according to the opening operation of the valve silicone cap 30 according to the internal pressure change of the storage container 70, A valve upper housing 50 having a plurality of air inflow holes 52 formed therein and forming a predetermined space therein while being exposed to the outside of the storage container 70, And a valve lower housing 40 having an air inlet / outlet hole 42 formed at a lower center of a valve operation space 44 forming a certain space while being positioned at a lower portion of the valve operating space 44. Thus, Thereby constituting the air automatic opening / closing valve 10 of the valve system.

Particularly, although the air automatic opening / closing valve 10 according to the present invention is constructed and operated as in the above-described structure and configuration, the structure of the valve silicone plug 30 is not limited to the structure of the air inlet hole 22 It is more preferable that the side sealing projection 34 is formed to extend and protrude from the side surface of the valve lower housing 40 to the side surface of the valve lower housing 40 so that the normally closed sealing operation with the valve cap support through 20 can be reliably maintained.

In addition, the present invention is not limited to the above-described basic construction of the air automatic opening / closing valve 10, so that the principle of the present invention operates. However, in the upper portion of the valve upper housing 50, The valve housing cover 60 may include a separate valve housing cover 60 so as to prevent foreign substances from entering into the valve housing 50 and to prevent leakage of contents from the storage container 70. In this case, The air inlet hole 62 is formed so that the outside air can be allowed to enter and exit.

That is, the air automatic opening / closing valve 10 of the present invention is installed on the upper side of the storage container 70 (which may be changed to be installed on the lower side or one side as needed) filled with a large amount of mainstream or beverage, A valve silicone plug 30 made of a flexible silicone material constituting the air automatic opening and closing valve 10 is provided in the storage container 70 only by the operation of the contents discharging means 80, The operation principle of automatically opening the air inlet hole 22 of the valve cap support 20 which is normally closed in accordance with the pressure change in the valve upper housing 50 and the valve cap Air from the outside is introduced into the interior of the storage container 70 through the air inlet holes 52 and 22 and the air inlet and outlet holes 42 of the support 20 and the valve lower housing 40, The working principle discharged through means (80) So to form the required configuration relationship.

The air automatic opening / closing valve 10, which is applied to the automatic air opening / closing apparatus of the mainstream and carbonated beverage canister of the present invention in which the above-described realization principle is operated, comprises an upper valve housing 50, A valve silicone cap 30 of a flexible material is divided into a valve lower housing 40 and an intermediate valve cap support 20 so as to be automatically inserted into the air inlet holes 22 And the contents 90 inside the storage container 70 are discharged to the inside of the storage container 70 through the air inlet and outlet holes 42 of the valve lower housing 40, The operation principle of being discharged to the outside through the contents discharging means 80 which is opened naturally by the pressure change due to the inflow of air can be realized. At this time, the discharged contents 90 are naturally supplied to the contents discharging means 80 When the open operation is stopped As the outside air is blocked from entering into the storage container 70 in the same there are no more external discharge of the contents 90 can be accurately stopped.

For reference, the present invention can be applied to a container storage container in which a large amount of beer is loaded. To be more specific, in order to be able to drink after being fastened to the bottom of the container container 70 as a storage container 70, a storage container (a can, a can and a fitting) Since the inside of the storage container 70 does not contain any air when the inlet for discharging the contents is opened, such as a contents discharging means 80 such as a conventional drain cock or a drain bowl for drinking beer while the bottom is rising, A vacuum pressure is generated inside the storage container 70 through the air automatic opening / closing valve 10 in which the system implementation principle is operated, and the vacuum pressure acts to draw outside air from the inside.

At this time, the valve silicone cap 30, which is a silicone valve installed in the Auto Air Open & Close Valve, opens the air inlet hole of the valve cap support 20 by the pressure of pulling the vacuum pressure, . When the contents discharging means 80 or the contents discharging inlet which are conventionally applied after the beer is closed is closed, the vacuum pressure inside the storage container 70 disappears, so that the valve silicone cap 30, which is a flexible silicone valve, is closed. That is, when the contents discharging means 80 and the contents discharging inlet are opened, air is introduced into the container 70, and when the container is inhaled again, the vacuum pressure of the storage container 70 is extinguished so that the inflow of air into the storage container 70 is stopped, The air automatic opening / closing valve 10 of the present invention does not communicate with each other and does not generate vacuum pressure inside the storage container 70 after drinking the beer as the contents 90. Therefore, The valve silicone cap 30 functioning as a silicone valve of the Auto Air Open & Close Valve is closed by closing the air inflow hole 22 of the valve cap support 20 to automatically block air inflow of the storage container 70 do.

As a result, since there is no air in the storage container (kane cans and fittings), it becomes a vacuum state as soon as the bottom is lifted up, and the contents 90 of the bottom part descend to the contents discharge inlet, instantaneously becoming a vacuumless state. In the vacuum state, a pressure to suck air from the outside is generated, and the vacuum pressure is applied to the valve cap support 20 while pulling the valve silicone cap 30, which is the silicon valve of the air automatic opening / closing valve 10 of the present invention. Outside air is introduced into the air inlet hole 52 of the valve upper housing 50 or both of the air inlet holes 62 of the valve housing cover 60 by the air inlet hole 22 of the valve cap support 20, The present invention is advantageous in that the external air can flow into the storage container 70 simply by the operation of the contents discharging means 80 in the storage container 70 filled with a large amount of mainstream or beverage, Is that introduced as the contents 90 to the automatic opening and closing device of the air liquor and beverage containers to discharge the drink can be realized.

In addition, the storage container 70 to which the air automatic opening / closing valve 10 according to the present invention is applied, after the content 90 is consumed, changes in the internal pressure of the storage container 70, The contents 90 inside the storage container 70 are pressed by the valve plug 30 so that the sealed state is structurally stable. Therefore, the content 90 of the storage container 70 does not come out to the outside, and in particular, when there is carbonic acid, the carbonic acid vaporizes to the upper layer, and the silicon valve is more strongly adhered due to the vaporization, Implementation principles that do not disappear into the outside of carbonic acid can be operated correctly.

That is, the air automatic opening / closing valve 10 applied to the automatic air opening / closing device of the mainstream and beverage container of the present invention is designed to operate the silicone valve of the Auto Air Open & Close Valve precisely Implementation principles can be exercised. For reference, the air automatic opening / closing valve 10 applied to the automatic air opening and closing apparatus of the mainstream and beverage container of the present invention is not limited to the drawing of the preferred embodiment and the above-described description level, and can be variously applied. The present invention can be conveniently applied to both the storage container of the present invention and the position thereof can be conveniently changed in position and structure according to the storage container of the object to be applied.

Particularly, the air automatic opening / closing valve 10 in which the operation principle of the present invention is exhibited can be installed in the opposite direction to the object such as the fruit storage container containing the plum wine, so that the carbonic acid generated from the contents from the storage container 70 is naturally discharged The new operating principle can also be applied. In addition, the air automatic opening / closing valve 10 of the present invention can prevent the intrusion of foreign matter structurally and reliably while preventing the valve housing lid 60 from being detached from the valve upper housing 50 when being transported during storage, It is needless to say that the specific construction level at which the operation principle of the present invention can be exhibited even in the state of being engaged can be applied to any extent without departing from the technical scope of the present invention.
