Description

Pressure regulating device and sealing and containing system comprising same Technical Field Embodiments relate to a pressure regulating device and a sealed containment system including the same. Background For food products, they spoil after a certain period of time due to their characteristics, and containers for long-term preservation of food products are required to maintain a closed characteristic to shut off the contact of the contained food with the outside air and/or moisture. The method for hermetically storing the food generally uses cans. In this type of can, since a metal can is used, it is difficult for a consumer to directly check the state of the food contained therein, and as a result, there is a limitation in that the consumer cannot directly check the state of the freshness of the food, etc., before purchasing the food. In addition, the sealing method of simply completely cutting off the food from the outside may be unsuitable depending on the type of food to be contained. For example, when the food contained in the container is a fermented food, the food generates a gas over time, which cannot be discharged to the outside of the closed container, and thus the container eventually bursts to cause a problem, or a problem that the contained food is easily spoiled may occur. Disclosure of Invention Technical problem As described above, there is a limit in the preservation and/or distribution of fermented foods, and there is an increasing demand for a method of sealing foods capable of maintaining the freshness of the fermented foods contained therein. An object of embodiments of the present invention is to solve the above-described problems and/or limitations, and in particular to provide a pressure regulating device capable of keeping contents fresh by exhausting gas while maintaining the airtight characteristics of fermented foods, and a sealed containing system including the same. Technical proposal In order to achieve the object, an embodiment can provide a container system comprising a container having a container portion inside, having a first face and a second face facing each other, the first face facing the container portion, selectively sealed so as to contain at least a gas-generating content in the container portion, and having at least one opening, and a pressure regulating device bonded to at least the second face of the container portion in a manner of covering the opening, the pressure regulating device being provided to discharge at least a part of the gas of the container portion to the outside when a first air pressure inside the container portion is higher than a second air pressure outside the container portion, and cut off inflow of the gas from the outside of the container portion when the first air pressure is lower than the second air pressure, wherein the pressure regulating device includes a first film structure provided so that a gas passing property in the container portion is larger than a liquid passing property in the container portion, and a second film structure provided to cover the film structure in a manner of covering the second film structure. The pressure regulating device may further include an adhesive film, which may be provided with one surface bonded to the second surface of the containing unit and the other surface bonded to the first and second film structures. The film having adhesiveness may be provided so as to be further located between the first film structure and the second film structure. The pressure regulating device may be provided so that the gas discharged from the inside of the accommodating portion through the opening is directed toward the second thin film structure after passing through the first thin film structure. The pressure regulating device may further include an adhesive film, which may be provided with one face bonded to the second face of the holding device and the first film structure, and the other face bonded to the second film structure. The pressure regulating device may further include an adhesive film, which may be provided with one face bonded to the second face of the holding device and the other face bonded to the first film structure. A portion of the second film structure may be provided to be bonded to the second face of the containing unit at least outside the first film structure. The pressure regulating device may further include an adhesive film, and a portion of the second film structure may be provided to be bonded to the second surface of the housing unit via the adhesive film at least outside the first film structure, and the adhesive film may be provided to be bonded to the second surface of the housing device on one side and to the first film structure on the other side. According to still another embodiment of the present invention, there may be provided a pressure regulating device capable of being coupled to a container having a container portion that contains at least a gas-generating content a
