BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid container and its valve, and more particularly, to a fluid container capable of completely shutting off the discharge of internal gas due to the fact that the gravity valve body can not be heard due to the Pascal principle even when the internal gas pressure of the fluid container is increased, .

Generally, the carbonic acid gas dissolved in the carbonated beverage has a phenomenon of escaping from the carbonated beverage and moving to the air layer.

In particular, a 1.5 liter large-volume PET bottle carbonated drink can not be used at one time and often opens the cap. Therefore, due to frequent opening, the carbon dioxide gas at the upper part of the container is diverted to the atmosphere, and a refreshing sensation that can be provided to the first carbonated beverage is lost, thereby losing a unique taste.

Accordingly, techniques for preventing the release of carbon dioxide gas are disclosed in Japanese Laid-Open Patent Publication Nos. 2010-0064470, 2002-0095444, and 1996-0031292, in which only the liquid content is discharged using a strobe, 0109640, Patent No. 10-1443150) and a manual stopper technology (Japanese Patent Laid-Open No. 2006-0006695).

However, the technique of discharging only the liquid content has a problem in that the structure is complicated, the number of parts is large and the manufacturing cost is high. Since the manual valve technology is manual, there is the same problem as the prior art unless attention is paid to closing the stopper. The technology has a gravity valve between the atmospheric pressure and the inner atmospheric pressure, so that when the inner pressure of the container is higher than the atmospheric pressure, the gravity valve is heard and the inner gas is released to the outside.

In particular, techniques for controlling the internal pressure of the container by using the principle that the gravity valve is heard are disclosed in, for example, Laid-open Patent Publication Nos. 2013-0027722, 2011-0104619, 2008-0025557, and Published Utility Model No. 1987-0013484.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a fluid container and its valve capable of preventing the release of internal gas by preventing lifting of the gravity valve body by the principle of Pascal even when the internal air pressure of the container is increased There is.

Another object of the present invention is to provide a fluid container and its valve which can be easily disassembled and assembled to easily perform internal cleaning, thereby enabling hygienic management.

It is still another object of the present invention to provide a fluid container and its valve which can reduce the production cost by simplifying the configuration and the number of parts.

In order to accomplish one aspect of the present invention, a fluid container of the present invention includes a container body having an opening at an upper end thereof, and a stopper and a valve detachably coupled to the opening of the container body.

The valve of the present invention includes a hollow outer housing detachably coupled to an opening of a container and forming a fluid passage, an inner housing fixed on the fluid passage of the outer housing and having a valve hole formed in a lower side wall thereof, .

The weight valve body is provided at its center with a through-hole communicating the upper surface and the lower surface, and is movably installed along the longitudinal direction of the inner housing. Accordingly, when the fluid container is squeezed, it moves in the first direction due to its own weight to block the valve hole formed in the side wall of the inner housing. When the fluid container is inclined at an angle greater than 90 degrees, the fluid container slides in a second direction opposite to the first direction by its own weight to open the valve hole formed in the side wall of the inner housing. In the case where the valve hole is blocked, the space in which the gravity valve element moves is sealed so that the internal air pressure of the fluid container is simultaneously applied to the upper surface and the lower surface. The stopper is formed at the lower end of the inner housing, and the lower surface of the gravity valve body is engaged to stop the movement in the first direction.

In an embodiment of the present invention, a flange is formed on an outer circumferential surface of the inner housing. A flange is interposed between the upper end of the fluid container and the outer housing to fix the inner housing on the passage of the outer housing. Such an assembling method facilitates the cleaning work by facilitating the detachment. In addition, since the flange itself acts as a gasket between the cap and the top of the container, it is possible to remove the separate gasket, thereby reducing the number of parts and lowering the production cost.

In one embodiment of the present invention, the gravity valve body slides along the inner circumferential surface of the inner housing, and the air pressure inside the container is reduced through the through-hole in the closed space formed between the upper surface of the inner housing and the upper surface of the gravity- . Therefore, even if the internal air pressure is higher than the self weight of the gravity valve body, there is no possibility of sound being heard because the air pressure acts uniformly in the upper and lower portions of the gravity valve body.

In another embodiment of the present invention, the gravity valve body is configured such that the inner circumferential surface of the through hole is slid along the outer circumferential surface of the inner housing, and the gap between the outer housing and the gravity valve body in an enclosed space formed between the flange and the upper surface of the gravity- The pressure inside the container can be transmitted. Therefore, even if the internal air pressure is higher than the self weight of the gravity valve body, there is no possibility of sound being heard because the air pressure acts uniformly in the upper and lower portions of the gravity valve body.

It is preferable that the outer housing of the present invention is detachably coupled to the opening of the container and the lower portion is detachably coupled to the upper mare piece. This structure makes it possible to remove the stoppers of the already dispensed liquid container and to use the valve of the present invention in combination.

A fluid container according to an embodiment of the present invention includes a container body having an opening at an upper end thereof, a stopper portion detachably coupled to the opening portion, and a valve fixed inside the opening portion of the container body. Wherein the valve has a cup-shaped housing in which a flange is formed at the upper end of the outer circumference, the flange is fitted in the opening and fixed on the fluid passage, and the valve hole is formed in the lower flange side wall, Wherein the inner circumferential surface of the through hole is slidably provided along the longitudinal direction on the outer circumferential surface of the lower portion of the flange and slidable in the first direction by self weight to block the valve hole when the fluid container is to be set, A gravity valve body which moves in a second direction opposite to the first direction due to its own weight when the valve body is tilted at a large angle and opens the valve hole; And an elastic locking projection for stopping the one-direction movement. Such a fluid container is provided with a peripheral body constituted by a valve inside a general indoor object, and the valve can be applied in the beverage container production stage.

The fluid container of the present invention and its valve according to the embodiments of the present invention as described above can completely prevent the gas discharge from the inside of the container by eliminating lifting of the gravity valve body by the Pascal principle.

Especially, even in case of a large capacity beverage container, since the internal gas emission is completely blocked, a refreshing drink can be enjoyed even after a lapse of time.

It also has excellent disassembly and assembling ability and can be easily cleaned, so it can be very hygienically controlled when used in beverage containers.

In addition, since the volatile gas inside the container can be effectively blocked, it is possible to prevent a safety risk due to fire or gas poisoning caused by the volatile gas.

However, the effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned above can be clearly understood by those skilled in the art without departing from the spirit and scope of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a diagram for describing a typical fluid container with a cap.

Referring to Fig. 1, a fluid container 10 includes a container body 12 and a stopper 14. An opening 16 for discharging the contents is formed on the upper end of the container body 12 and a male screw 18 is formed on the upper end peripheral surface so that the stopper 20 is threadedly engaged. The mouthpiece 14 is removed to release the contents inside the container body 12 and the opening 16 is opened. A female thread 19 is formed on the inner peripheral surface of the stopper 14.

FIG. 2 is a view for explaining a state of a fluid container having a valve according to a preferred embodiment of the present invention, and FIG. 3 is a view for explaining a state of releasing contents by inclining a fluid container having a valve of the embodiment of FIG. Fig.

Referring to the drawings, the valve 20 includes a hollow outer housing 22, an inner housing 24, a gravity valve body 26, and a stopper 28.

The hollow outer housing 22 is formed into a tubular shape divided into two stages, that is, an upper portion 22a having a small inner diameter and a lower portion 22b having a large inner diameter. A male thread 22c is formed on an outer circumferential surface of the upper portion 22a so as to be removable and a female thread 22d is formed on the inner circumferential surface of the lower portion 22b so as to be detachable from the outer circumferential surface of the upper end of the container body 12 .

The inner housing 24 includes a main body 24a in the form of a cap cylinder having an upper end closed and a lower end opened, and a flange 24b on the outer peripheral surface of the lower end of the main body. At least one valve hole 24c is formed in the side wall near the flange 24b of the main body 24a. The inner space of the main body 24a forms a space or compartment 24d isolated by the gravity valve body 26. [

The gravity valve body (26) is formed with a weight of a cylindrical shape having a through hole (26a) communicating between an upper surface and a lower surface at the center. The gravity valve body 26 is slidably mounted in the inner space of the main body 24a of the inner housing 24 along the longitudinal direction.

A stopper 28 is integrally formed at the lower end of the inner housing 24. [ The stopper 28 may be composed of a plurality of elastic catch protrusions 28a protruding downward and arranged at regular intervals, for example. At the lower end portions of the respective elastic locking projections 28a, a locking protrusion 28b protruding toward the center is formed. The lower surface edge of the gravitational valve body 26 is caught by this stopping stop 28b to stop the sliding movement. The elastic locking projections 28a are pushed outwardly when the gravity valve body 26 is assembled and the gravity valve body 26 is inserted into the inner space of the main body 24a of the inner housing 24 through the engagement step 28a It is restored to its original position and serves as a stopper. The stopper 28 is easily deformable in any of various embodiments, such as an E-ring, in addition to the embodiments described above.

The gravity valve body 26 has a height such that the upper surface of the gravity valve body 26 can close the valve hole 24c at a position higher than the valve hole 24c in a state where the lower surface of the gravity valve body 26 is caught by the engaging step 28b. The inner housing 24 has a length such that the gravity valve body 26 slides and the lower surface moves to a higher position of the valve hole 24c so that the valve hole 24c is completely opened.

Thus, the valve hole 24c is closed or opened by the side wall of the gravity valve body 26.

In the state where the gravity valve body 26 is assembled to the inner housing 24 and the flange 24b of the inner housing 24 is engaged with the upper end of the container, the lower portion 22b of the outer housing 22, The flange 24b can be fixed between the outer housing 22 and the upper end of the container by the pressing jaws of the outer housing 22 so that the inner space of the container can be kept airtight. The flange 24b itself may serve as a gasket. In this case, a gasket such as an O-ring may be additionally disposed at a portion of the flange 24b that is to be subjected to an external interview.

2, the valve hole 24c is closed by the gravity valve body 26, so that the gas in the container is discharged through the through hole 26a of the gravity valve body 26 into the compartment 24d ), So that the air pressure in the container is maintained at the same level as the pressure inside the container. Therefore, the gravity valve body 26 can not hear the gravity valve body 26 even if the container internal air pressure rises because the same pressure acts on the upper and lower surfaces of the gravity valve body 26 in accordance with the Pascal principle The closed state of the valve hole 24c can be maintained as it is.

3, the gravity valve body 26 slides on the inner circumferential surface of the inner housing 24 by its own weight in the direction of the closed upper end, and the valve hole 24c, Lt; / RTI > The contents inside the container are discharged to the outside through the upper opening of the outer housing 22 through the valve hole 24c opened in the arrow direction shown in the figure.

It is possible to screw the stopper piece 14 of the container to the male screw 22c of the outer housing 22 to double the container opening in the state of the container.

As described above, according to an embodiment of the present invention, the gravitational valve body slides along the inner circumferential surface of the inner housing, the inner circumferential surface of the inner housing and the upper surface of the gravity valve body, Is transmitted. Therefore, even if the internal air pressure is higher than the self weight of the gravity valve body, there is no possibility of sound being heard because the air pressure acts uniformly in the upper and lower portions of the gravity valve body.

In the above embodiment, the cylinder and the gravity valve body of the inner housing are not limited to the cylindrical shape but are easily deformable into a polygonal columnar shape. The through hole of the polygonal column-shaped gravity valve body is not centered, It may be constituted by a gap or a groove formed vertically.

And the inner circumferential surface of the through hole 36a of the gravity valve body 36 is slidably coupled along the outer circumferential surface of the inner housing 34. [ And the engaging protrusions 38b of the elastic locking projections 38a constituting the stopper 38 are protruded in the direction opposite to the center so that the edge of the lower surface of the gravity valve body 36 is caught.

The valve 30 of the other embodiment is provided with the compartment 34d between the flange 34b and the upper surface of the gravity valve body 36 and the gap 36b between the inner surface of the container and the outer surface of the gravity valve body 36, The inner pressure can be propagated to the compartment 34d through the first and second chambers 34a and 34b and the same pressure can be applied to the upper and lower surfaces of the gravity valve body 36. [
