{DEVICE FOR CONTROLLING THE GAS}

The present invention relates to a gas discharge control device, and more particularly, to a gas discharge control device capable of discharging a gas inside a container to the outside of the container.

BACKGROUND ART [0002] In general, containers for the purpose of selling kimchi, miso, kochujang, makgeolli, nuts and the like are made of synthetic resin containers, packed containers formed of aluminum, paper, or vinyl.

However, due to the characteristics of such a fermented food, gas is generated during the fermentation process, and the pressure inside the container rises due to the fermentation gas, resulting in swelling of the container and leakage of the contents inside the container. In order to overcome such problems, containers capable of discharging gas are being developed.

For example, in the prior art Korean Patent Registration No. 10-1375609, it is explained that a vent hole for discharging the gas, a membrane film is attached so as to block the outflow of the contents and to enable selective discharge of gas.

In the case of such a conventional technology, although the internal gas can be discharged through the membrane film, there is a problem that gas and bacteria from the outside may be introduced and the contents may be deteriorated.

Particularly, in the structure of the prior art, a guide ring for stably securing a discharge space for gas and blocking deformation is formed in the vent hole, which can be in direct contact with the contents inside the container and is separated from the membrane film and the carbon film, There is a problem that it can be mixed into the inside. In addition to the above-mentioned prior art, several similar or similar problems are found in the prior art.

The first object of the present invention is to solve the above problems, and it is a first object of the present invention to provide a gas discharge apparatus and a gas discharge apparatus which are capable of discharging gas generated by fermentation, etc., And a control device.

A second object of the present invention is to provide a gas discharge control device capable of preventing gas, bacteria, or the like from entering the inside of the container from the outside.

The object of the present invention is to provide a gas discharge regulating device which is attached to one surface of a container and discharges the inner gas of the container to the outside, the hard film comprising at least one of a discharge hole and a first discharge incline improvement; A flexible film which is positioned on an upper portion of the hard film and has a discharge hole or a second discharge incline improvement which is offset from the first discharge incision line, And a non-woven fabric which is positioned under the hard film and is subjected to hydrophobic treatment.

Here, the thickness of the flexible film may be thinner than the thickness of the hard film, and the flexible film may be one surface incised along the second discharge incline when the internal gas is evacuated from the container is tilted toward the outside of the container.

Further, the wet film may further include a wet film positioned on the lower surface of the nonwoven fabric, and the wet film may have adhesiveness on one surface or the entire surface.

According to one embodiment of the present invention, exhaust holes and cutouts are formed to allow gas generated by fermentation or the like to be discharged to the outside of the container.

Here, the flexible film 200 causes the flexible film 200 to swell up when the gas inside the container is discharged, and to discharge the flexible film 200 to the outside through the second discharge incineration 210 and 220. On the contrary, The flexible film 200 is brought into close contact with the hard film 100 to block the inflow of external gas. In this way, the inner gas is discharged and the inflow of the external gas is blocked, thereby preventing the contents in the container from being altered or the container from being deformed or damaged.

The above-mentioned container is used as a concept including a container body and a container cover, and a 'container' to which the embodiments according to the present invention are applied is applied to both the container body and the container cover. The container opening can be determined depending on the type of the discharged gas, the amount of discharged gas, the size of the container, and the like.

Hereinafter, the configuration of the first embodiment will be described in detail with reference to the drawings.

1 is an exploded perspective view of a gas discharge control device according to a first embodiment of the present invention, which is an exploded view of the configuration of a gas discharge control device. As shown in FIG. 1, the hard film 100 is formed in a disc shape, and one discharge through hole 110 is formed at the center thereof. Though the thickness of the hard film 100 is 100 탆 or more, it is preferable that the hard film 100 is formed in consideration of the kind of the discharged gas, the amount of discharged gas, the shape and size of the container, and the like. In the first embodiment, the discharge through hole 110 is formed in a circular shape at the center of the hard film 100, but it may be a triangular shape, a square shape, or an amorphous shape and is mixed to form a plurality of discharge holes 110 . Alternatively, the first exhaust incision line and the exhaust hole 110 may be formed at the same time. The first discharge incline improvement may be formed by a curved line or a broken line instead of a straight line, and may be incised by a pattern to be shaped. In addition, the first exhaust incision line and the exhaust through-hole 110 may be formed in various shapes and various positions in consideration of the type and amount of discharged gas, the shape and size of the container, .

The flexible film 200 is located on the top of the hard film 100 and is formed in the same disc shape as the hard film 100. It is preferable that the thickness is less than 4 탆 to 100 탆 and is formed to be thinner than the hard film 100. In this flexible film 200, one second discharge incision 210 is formed, and the one side of the flexible film 200 cut along the second discharge incision 210 is bent toward the outward direction of the container so that the inner gas of the container is discharged to the outside of the container .

The second discharge incision 210 is formed to be offset from the discharge through hole 110 or the first discharge incision line. In this embodiment, the flexible film 200 has adhesiveness to one side or whole surface contacting the hard film 100, More specifically, the adhesive is adhered to one side of the hard film 100, which is in contact with the hard film 100 at all times or in the form of adhesive on the front side. Pressure is generated inside the container, The one incised along the improvement 210 may be tilted outwardly of the container.

This will be described in more detail with reference to FIG. 2 to be described later.

As described above, the second discharge incision 210 is formed in the flexible film 200 of the first embodiment. However, the second discharge incision 210 can be formed in more than one in consideration of the discharge amount of the gas, the kind, and the shape of the container , And the second exhaust incision improvement 210 is formed to be mutually shifted from the exhaust through-hole 110 or the first exhaust incision line to enable efficient discharge of the internal gas.

The second discharge incision 210 may be formed by a curved line or a broken line rather than a straight line. The second discharge incision 210 may be cut into a pattern to be shaped, and may be formed of a hard film 100 and a flexible film 200 may be made of various films or sheets using materials such as polyethylene (PE), polypropylene (PP), polyester (PET), polycarbonate (PC) .

On the other hand, the nonwoven fabric 300, which is formed in the shape of a disk and located on the lower surface of the hard film 100, is a mixture of natural fibers or chemical fibers, and serves as a gas discharge passage in this embodiment. The shape and thickness of the hard film 100 are not limited, but it is preferable that the first film is formed in a shape and thickness taking into consideration the first discharge incisional reduction formed in the hard film 100 or the contents outflow through the discharge vent 110. In the first embodiment, the nonwoven fabric 300 is hydrophobized so as not to be permeable to liquid. The nonwoven fabric 300 may be formed into various shapes using natural fibers such as polyester (PET), polypropylene (PP), polyethylene .

FIG. 2 is a cross-sectional view showing a state in which a first embodiment of a gas discharge control device according to the present invention is attached to a container to discharge an internal gas, FIG. 3 is a cross- Sectional view showing a state in which the inflow of gas is shut off. As shown in FIGS. 2 and 3, when gas is generated by the contents inside the container, the gas moves along the gas discharge direction GD and flows into the nonwoven fabric 300, the discharge through hole 110, (210, 220). At this time, the hard film 100 maintains its original shape, and the flexible film 200 has one side incised along the second discharge incision 210 being bent outward in the direction of the container. Here, a double-sided tape or various types of adhesive may be applied on the cut surface in accordance with the type of gas to be discharged, the amount of gas discharged, the size of the container, and the like.

On the contrary, when the gas flows outside the container along the gas inlet direction (OD), the flexible film 200 and the second discharge incision 210 adhere closely to the upper surface of the hard film 100, Thereby blocking the inflow. At this time, in order to reliably block the inflow of the external gas, it is preferable that the discharge vent 110 and the second discharge incision 210 are mutually shifted so as not to come into contact with each other.

The hard film 100, the flexible film 200, and the nonwoven fabric 300 may have the same shape and the same diameter. However, in consideration of the type of discharged gas and the size of the container to be packed, As shown in FIG. In addition, a double-faced tape may be adhered to one surface or whole surface of the substrate, and then adhered so as not to be separated from each other by various methods such as thermal bonding and impulse bonding. In addition, in order to attach to a container body such as a can, a plastic bottle, or a container lid, it is possible to attach the flexible film 200 using a double-sided tape on the entire surface or one surface thereof. Here, it is preferable that the double-sided tape is harmless to the human body and does not cause a chemical reaction with the internal gas or the contents inside the container.

As described above, the flexible film 200 may have adhesiveness to one side or the entire surface contacting the hard film 100, and may have adhesiveness. The flexible film 200 may be harmless to the human body, No chemical reaction should occur.
