The present invention relates to a fermented food packaging container, and more particularly, to a fermented food packaging container that stores fermented foods such as kimchi and the like and is capable of smoothly discharging carbon dioxide gas generated from fermented foods to the outside.

Generally, fermented foods such as kimchi, soybean paste, kochujang, and salted fish are continuously fermented in the packaging and distribution process due to the characteristics of the product among the foodstuffs stored and distributed in the storage means such as the PET material packing container or the retort pouch.

In this case, in the fermented food, carbon dioxide gas is generated due to the decomposition of the organic compound, which not only changes the taste of the fermented food but also increases the pressure inside the storage means to expand the storage means, Resulting in deterioration of product quality.

Therefore, in order to solve the above-mentioned problems, in the related art, a defoaming agent or a gas adsorbent is enclosed in a storage means together with a fermented food to remove carbon dioxide gas generated from the fermented food, or a gas discharge means in the form of a check valve So that the user operates the gas discharging means to discharge the carbon dioxide gas in the storage means to the outside.

However, since chemical products such as defoamers and gas adsorbents are housed in the storage means directly exposed to the fermented food, when the product is opened, the defoamer or the gas adsorbent is visually exposed to damage the aesthetics, There has been a problem in that the product has a sense of heterogeneity and the consumption desire is lowered.

FIG. 7 is a perspective view illustrating a container for fermented food packaging according to the second embodiment of the present invention. FIG. 8 is a view showing a filtration layer provided in a membrane filter of a fermented food packaging container according to a second embodiment of the present invention. FIG. 9 is a view showing a membrane filter of a fermented food packaging container according to a fourth embodiment of the present invention.

3, the membrane filter 100 includes a first support layer 10, a second support layer 20, and an open / close layer 30 disposed between the first support layer 10 and the second support layer 20 can do.

The first support layer 10 may be attached to one surface of the sealing part 300 where the gas exhaust hole 300a is formed and a first flow path 11 communicating with the gas exhaust hole 300a may be formed inside. The second support layer 20 is attached to the surface of the open / close layer 30 to be described later, and a second flow path 21 for guiding the carbonic acid gas G introduced from the outside to the open / close layer 30 side is formed inside .

More specifically, the first support layer 10 and the second support layer 20 are formed of a waterproof material (e.g., plastic or the like) that is difficult to pass carbon dioxide gas G and moisture, and are formed along the axial direction And may be formed in a ring shape having a predetermined thickness. Through this, a flow path (a first flow path 11 and a second flow path 21) having a predetermined length in which carbon dioxide gas G can move along the axial direction can be formed inside. The inner diameter d1 of the first support layer 10 on which the first flow path 11 is formed may be larger than the inner diameter d2 of the second support layer 20 on which the second flow path 21 is formed. In order to increase the pressure of the carbon dioxide gas G passing through the second flow path 21, the second flow path 21 is formed to have a smaller width than the portion where the opening / closing means 30 is formed, In consideration of interference with the opening / closing means when the opening / closing means is rotated, the opening portion 11 may be formed to have a larger width than a portion where the opening / closing means is formed. For example, the first flow path 11 and the second flow path 21 may have a structure in which the width of the cross section gradually decreases toward the gas discharge hole 300a. This makes it possible to further improve the speed and pressure of the carbonic acid gas (G) passing through each flow path.

Here, the second support layer 20 may have a structure capable of accommodating therein the first support layer 10, the open / close layer 30, and a filtration layer 40 described later.

4, the second supporting layer 20 includes a first receiving groove 23 for receiving the first supporting layer 10 and the opening and closing layer 30 and a second receiving groove 25 for receiving the filtering layer 40 May be formed.

More specifically, the first support layer 10 and the open / close layer 30 are accommodated on one side of the second support layer 20, and the center axis of the second support layer 20 and the center axis of the first support layer 10, A first receiving groove 23 for supporting the outer circumferential surfaces of the first supporting layer 10 and the opening and closing layer 30 may be formed so that the central axes of the first supporting layer 10 and the opening and closing layer 30 are aligned with each other. The outer circumferential surface of the filtration layer 40 is formed so as to correspond to the center axis of the filtration layer 40 and the central axis of the second support layer 20, The second receiving groove 25 can be formed.

Therefore, the first and second receiving grooves 23 and 25 of the second support layer 20 can be formed without the need of performing a separate process in order to align the centers of the respective material layers when the membrane filter 100 is manufactured. The centers of the respective material layers can be precisely matched only by laminating the first support layer 10, the open / close layer 30, and the filtration layer 40 on the first support layer 10, thereby preventing the separation of the respective material layers.

Meanwhile, a plurality of cutting grooves 13 may be formed on one surface of the first support layer 10 attached to the surface of the receiving portion 200.

5, a plurality of cut-away grooves 13 are formed on one surface of the first support layer 10 along the circumferential direction, and each of the cut-out grooves 13 extends along the radial direction of the first support layer 10 . ≪ / RTI > Therefore, even when the surface of the portion where the first support layer 10 is to be contacted is not planar (e.g., bent or curved), the first support layer 10 Can be easily deformed into a shape corresponding to a part to be contacted.

3, the opening / closing layer 30 may include opening / closing means attached to the surface (other surface) of the first supporting layer 10 to block the first flow path 11 and open only under predetermined conditions .

More specifically, the opening / closing layer 30 includes a body portion 33 attached to the first support layer 10 and the second support layer 20, as shown in Fig. 6, and a portion of the body portion 33, And an opening / closing part 31 rotatably formed on the body part 33. Therefore, when the carbon dioxide gas G flows into the second flow path 21, the opening and closing part 31 is rotated to open to one side so that the first flow path 11 and the second flow path 21 communicate with each other The carbon dioxide gas G flowing into the second flow path 21 can be moved to the first flow path 11. [ For example, the open / close layer 30 may be formed in the form of a film having a waterproof property. The opening and closing part 31 is formed with a plurality of the second flow paths 21 so that the carbon dioxide gas G can be discharged to the outside of the receiving part 200 more quickly.

The opening and closing part 31 may be formed to be opened only when the carbon dioxide gas G flowing into the second flow path 21 is moved toward the gas discharge hole 300a. That is, the opening and closing part 31 may be formed in a structure that does not open the flow passage when an external force is applied in the opposite direction (the direction from the first flow path 11 to the second flow path 21).

6, the cut portion between the body portion 33 and the opening / closing portion 31 extends from the second flow path 21 toward the first flow path 11, D1, and D2 are gradually widened. Therefore, even when air or the like flows into the first flow path 11 from the outside, the opening and closing part 31 is supported by the inclined boundary part formed on the body part 33 and the second flow path 21 is closed Lt; / RTI > On the other hand, the opening / closing unit 31 is not limited to the above-described structure, and can be applied to various other structures. For example, referring to FIG. 7, a support member 35 may be formed on the opening and closing part 31 to be supported on the outer surface of the body part 33 exposed toward the first flow path 11 side.

In addition, the membrane filter 100 of the fermented food packaging container 1 may include a filtration layer 40.

3 and 8, the filtration layer 40 is attached to the surface of the second support layer 20 to filter the carbon dioxide gas G flowing into the second flow path 21, Or the like.

More specifically, the filtration layer 40 has a first filtration part 40 having one side exposed to the accommodation space 200a where the fermented food 2 is stored, and performing functions such as dehumidification, deodorization, And a second filtration unit 43 attached to the other surface of the first filtration unit 41 to pass the carbon dioxide gas G and block the liquid (moisture).

The first filtration unit 41 is exposed on the one side of the accommodation space 200a of the accommodation unit 200 in which the fermented food 2 is stored and the catalyst of the activated carbon, Impregnated) air permeable nonwoven fabric material.
