DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust structure for a fermented food container, and more particularly, to a container for discharging fermented gas naturally generated in a fermented food container to the outside by using a check valve. The present invention relates to an exhaust structure for a fermented food container that prevents damage or a decrease in commercial value.

[0002]

2. Description of the Related Art Generally, fermented foods such as kimchi, gochujang (pepper miso), miso, and salted foods are loaded into a predetermined container, and then, due to the chemical characteristics of the filling, Generates fermentation gas. The fermentation gas in the container may increase the pressure inside the container to expand the container, change its shape, and cause the filling or contents to overflow between the container lid and the container body.

[0003] The storage container for such fermented foods is
Due to the characteristics of the fermented food, the quality of the contents is not reduced, but the appearance is damaged, the value as a product is reduced, and in some cases, the container may be damaged. Such fermented foods are packaged by various packaging methods. For example, using a retort pouch method using a multilayer film, a tray-type container packaging method in which a multilayer film is covered on a vacuum-molded or injection-molded container such as PP, and a general packaging container such as a PET bottle, a glass bottle, etc. That is the method of packaging.

[0004] In recent years, a method has been proposed in which a freshness preserving agent is introduced into a container in order to efficiently treat gas generated by fermented food in the container. In this method, a gas absorbent and a deoxidizer are separately packaged in a sheet material through which a gas is permeable and a liquid is not permeable, and the fermentation gas is treated by putting the gas absorbent and the oxygen absorber into a container together with the contents.

[0005]

However, such a method of accommodating a sheet material filled with a freshness preserving agent involves a process in which fermented foods are conveyed or displayed, and the contents in the container are forced to fluctuate. In addition, the surface of the sheet of the liquid impermeable and gas permeable material enclosing the freshness preserving agent comes into contact with the highly viscous contents.

In this case, the sheet material structure φ0.0004μ-φ
The 0.1 micron pores come into contact with highly viscous contents, and the sheet material structure is closed. As a result, the gas generated from the fermented food cannot pass through the sheet material and the freshness-preserving agent cannot function, so that the gas in the container cannot be discharged smoothly. As a problem caused by carelessness of the user, for example, in the case of a container such as a retort pouch, a knife or the like is usually used when opening the container, but when the container is cut, the freshness is maintained due to carelessness of the consumer. The sheet material enclosing the agent is cut together, and the powder of the freshness-preserving agent containing chromium such as potassium dichromate and potassium permanganate, which is undesirable for the human body, spills over the contents, and the contents are removed. You may need to discard.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem of a conventional container for packaging fermented food, and has been devised to solve the problem.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) Hereinafter, a preferred embodiment of an exhaust structure for a fermented food container according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing an installation state of an exhaust structure of a fermented food container according to the present invention, FIG. 2 is an exploded perspective view showing a structure of a main part of the present invention, and FIG. 3 is a first embodiment of the present invention. FIG. 4 is a sectional view showing
FIG. 1 is a plan view showing a first embodiment of the present invention.

First, as shown in FIG. 1, the exhaust structure of the present invention is closely attached to the bottom of a film 12 having an exhaust hole 12a formed in the upper part of a container 10. The exhaust structure comprises an operating valve 20, a valve seat 30 for holding the operating valve 20, and a fixed body 40 for fixing these two parts to the bottom of the film 12. Figure 2
As shown in FIG. 4 to FIG. 4, the operating valve 20 is formed of an elastic material, and the valve seat 30 is
A fitting column 22 for fitting is formed at the center, and a projection 22a is formed at an end edge of the fitting column 22 to prevent inadvertent detachment after fitting. The outer peripheral edge of the operation valve 20 forms a flap 24 having a 'V'-shaped cross section, which is more flexible than other parts, in order to smoothly exhaust the exhaust gas in the container to the outside. A filter 42 for exhausting only gas in the contents to the outside is provided at the bottom. The filter 42 may be made of a material having a high air permeability and an internal water pressure of about 550 mm water head. Reference numeral 26 indicates the upper surface of the operation valve 20 described above.

The valve seat 30 has a plurality of swirling projections 31 formed at the center upper portion for condensing water vapor in the fermentation gas, and a vertically penetrating center portion for accommodating the fitting column 22 of the operating valve 20. An alignment hole 32 is formed, and an inner peripheral edge is formed as a slope 34 so as to correspond to the flap 24 having the cross section of the 'V' shape. Further, a flange 36 is formed on the outer peripheral edge so as to be in close contact with the bottom surface of the film 12, and a protruding ring 38 is formed on the bottom outer peripheral edge for fitting to the fixed body 40.

A filter 42 for exhausting only the fermentation gas is provided at the bottom of the operation valve 20. Since the filter 42 is disposed on the space 54 formed by the protrusion of the protruding ring 38, a slight gap is formed between the bottom of the fixed body 40 and the filter 42. Next, the fixed body 40 that holds and fixes the above-described components and the like on the film 12 will be described. The fixed body 40 has a plurality of radial grooves 46 and inclined radial grooves 46a formed radially and narrower toward the center on a fixed flange 44 formed by extending the outer peripheral edge thereof. A protrusion ring fixing groove 48 is formed at an inner corner to receive the protrusion ring 38. The inclined radiation groove 46a is formed to extend from the radiation groove 46 so as to be inclined downward inward.

In this embodiment, four fusion projections 44a are formed on the fixed flange 44 at regular intervals. This is provided in a limited manner in order to enhance the easiness of manufacture when attached to the bottom surface of the film 12. The actuation valve described above
When the valve 20 and the valve 30, and the valve seat 30 and the fixed body 40 are assembled respectively, a certain gap exists between them according to a preset value. That is, between the operating valve 20 and the valve seat 30, the swirl chamber 60 and the condensed water storage chamber 62
Between the valve seat 30 and the fixed body 40.
64 are respectively formed and exhibit an automatic exhaust function of fermentation gas described later. When the operation valve 20 and the valve seat 30 are assembled, a check valve is formed as a result.
In FIG. 3, reference numeral 14 indicates the inside of the container 10.

Next, the operation of the exhaust structure of the fermented food container of the present embodiment having the above-described structure will be described. Figure 3
As shown in (1), food is fermented immediately after the fermented food such as miso or gochujang is filled in the container 10, and the internal pressure is increased by the fermentation gas in the closed space. The gas generated from the inside 14 of the container 10 moves radially on the fixed flange 44 and along a plurality of radial grooves 46 formed at equal intervals, and inwardly forms the inclined radial grooves 46a inclined downward. It passes continuously and spreads out to the room 64. At this time, even if the highly viscous content flows into the radiation groove 46 together with the gas due to the shaking or tilting of the container 10, the content is formed narrower toward the center, so that the content is moved toward the center. The greater the movement, the higher the osmotic pressure is required, and the contents are positively suppressed from being moved into the gas exhaust structure of the present embodiment.

Another function of the radiation groove 46 will be described. Since the plurality of radiation grooves 46 function as a discharge passage, even if a part of the radiation groove 46 is closed by a highly viscous liquid material. It is possible for the fermentation gas to move through the remaining radiation grooves 46, and the function of the exhaust gas is not lost. If the container 10 is opened within a short period of time after the contents have been filled, the function of the spare space 64 alone will suffice for the treatment of the generated gas. But room
If the container 10 is not opened until the gas is filled in the chamber 64, the fermentation gas sequentially passes through the filter 42 and the fitting hole 32 mounted on the bottom surface of the valve seat 30.

Subsequently, the gas flows into the swirl chamber 60 and the condensed water storage chamber.
When it reaches 62, the flap 24 of the actuating valve 20 and the slope 34 of the valve seat 30 come into contact with each other and are shut off from the outside. The gas swirled in the swirling chamber 60 gradually increases the internal pressure, and becomes a positive pressure state that breaks the pressure balance with the external pressure. Swirl chamber
When the condensed water storage chamber 60 and the condensed water storage chamber 62 are in a positive pressure state, the flap 24 of the operating valve 20 and the slope 34 of the valve seat 30 release the contact state, as indicated by the phantom lines in the reference enlarged view of FIG. Then, the gas in the interior 14 of the container 10 is exhausted in the direction of the arrow.

Next, the condensed water storage chamber 62 will be described. Volatile steam contained in the fermentation gas is supplied to the vortex chamber.
The condensed water generated by being condensed while hitting the surrounding surface while swirling at 60 is stored in the condensed water storage chamber 62.
Thereby, it is possible to prevent the exhaust holes 12a from being stained by water or from being contaminated, and to enhance the merchantability.

On the other hand, when the outside of the container 10 is in a positive pressure state or the container 10 is overturned, entry of foreign substances such as dust, powder or liquid is completely blocked, and penetration into the inside is suppressed. You. That is, since the elasticity of the flap 24 of the operating valve 20 is made of a very flexible material and the cross section is formed in a “V” shape, the check valve restricts the movement of the object in one direction. It exerts its function and can completely prevent invasion of foreign substances from the outside. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. FIG. 5 is a sectional view showing a second embodiment of the present invention, and FIG. 6 is a plan view showing a second embodiment of the present invention. The same parts performing the same functions as in the first embodiment will be denoted by the same reference numerals, and the description will be omitted to avoid complication.

The difference between the second embodiment and the first embodiment is that
The point is that a gas absorbent, that is, a freshness preserving agent is enclosed and provided on the gas exhaust path. In order to enclose a freshness preserving agent on a gas inflow path flowing through the radiation groove 46 of the fixed body 40,
The outside of the bottom of the fixed body 40 is formed by a freshness retaining agent storage cylinder 70. The storage cylinder 70 has an inlet 72 communicating with the radiation groove 46, and a filter 52 is installed at the inlet 72. Other configurations and operations are the same as those of the first embodiment.

In this case, since most of the viscous liquid substance cannot reach the storage cylinder 70,
The micropores of the 70 filter 52 are prevented from being blocked, and the effect of the freshness preserving agent is doubled. As described above, the exhaust structure of the fermented food container according to the present embodiment employs a filter and a check valve in the fermented food storage container to effectively exhaust gas generated inside to the outside and store condensed water therein. And
The appearance of the container can be cleaned to enhance the merchantability.

Then, a storage cylinder containing a freshness preserving agent is formed integrally with the fixed body on the fermentation gas discharge path to extend the storage time of the fermented food as a small amount of freshness preserving agent. Eliminates incision of the holding agent sheet material together with the container, and eliminates the inconvenience that the freshness holding agent powder that is undesirable for the human body scatters in the contents of the food and the contents must be discarded. Of course, it is suitable for storing fermented foods as well as various packaging methods such as retort pouch method, tray type container, PET bottle, glass bottle, etc. It can be applied to various packaging containers.

[0027]

As described above, according to the exhaust structure for a fermented food container according to the present invention, the principle of the check valve is applied to the storage container for the fermented food, and the fermented gas generated in the packaging container is applied. Can prevent swelling and breakage of the packaging container, prolong the storage period of the fermented food, prevent the container from falling down or swaying in the distribution process, and block the exhaust passage of the contents, thereby increasing the commercial value. .
