본 발명은 공기충전형 포장재에 관한 것으로, 보다 상세하게는 공기의 주입을 보다 용이하게 함과 더불어 주입된 공기의 밀봉을 보다 확실하게 보장할 수 있는 공기충전형 포장재에 관한 것이다.The present invention relates to an air-filled packaging, and more particularly, to an air-filled packaging that can more easily ensure the injection of air and ensure the sealing of the injected air more reliably.

본 발명은 공기충전형 포장재에 관한 것으로, 보다 상세하게는 공기의 주입을 보다 용이하게 함과 더불어 주입된 공기의 밀봉을 보다 확실하게 보장할 수 있는 공기충전형 포장재에 관한 것이다.The present invention relates to an air-filled packaging, and more particularly, to an air-filled packaging that can more easily ensure the injection of air and ensure the sealing of the injected air more reliably.

최근에는 이러한 포장재의 완충성을 구현하기 위하여 포장재의 외부에 합성수지 필름을 적용하고, 복수의 에어셀을 가설하여 포장재의 내부에 공기를 주입함으로써 그 완충성을 향상시킨 공기충전형 포장재가 널리 개시되어 있다.Recently, in order to realize the buffering property of the packaging material, a synthetic resin film is applied to the outside of the packaging material, and a plurality of air cells are installed, and air-filled packaging materials having improved its buffering properties by injecting air into the packaging material have been widely disclosed. .

하지만, 이러한 종래의 공기충전형 포장재는 그 복수의 에어셀에 공기를 주입하고 밀봉하기 위한 체크 밸브의 완성도에 따라 그 성능이 크게 좌우되는데 이 체크밸브의 재질이 매우 까다롭고 작업 공정이 복잡한 단점이 있었다.However, such a conventional air-filled packaging material greatly depends on the completeness of the check valve for injecting and sealing air into the plurality of air cells, and the performance of the check valve is very difficult and the work process is complicated. .

본 발명은 상기와 같은 것을 감안하여 안출한 것으로, 고품질의 체크밸브가 필요치 않고 공기충전형 포장재의 제조공정을 단순화하는데 그 목적이 있다.The present invention has been made in view of the above, and an object thereof is to simplify the manufacturing process of an air-filled packaging material without requiring a high quality check valve.

또한, 본 발명은 복수의 에어셀 중에서 어느 일측 또는 일부의 에어셀이 파손되더라도 나머지 에어셀들의 밀봉성에는 영향을 미치지 않아 그 완충적인 포장기능을 지속적으로 유지할 수 있는 공기충전형 포장재를 제공하는 데 그 목적이 있다.In addition, the present invention does not affect the sealing of the remaining air cells even if any one or some of the air cells of the plurality of air cells is provided to provide an air-filled packaging material that can continuously maintain the cushioning packaging function have.

상기와 같은 목적을 달성하기 위한 본 발명의 공기충전형 포장재는 상부시트와 하부시트의 접착으로 구획 형성되어 외부의 압력에 대한 완충작용을 하는 하나 이상 에어셀; 외부로부터 공기가 주입될 수 있도록 상부시트와 하부시트의 접착으로 에어셀 상부에 구획 형성되는 공기주입통로; 일측은 상기 공기 주입통로로부터의 공기 유입을 위해 상기 공기주입통로와 연결되고, 타측은 상기 에어셀로의 공기 배출을 위해 상기 에어셀과 연결되도록 상부시트와 하부시트의 접착으로 구획 형성되는 소통로; 및 상기 에어셀로의 공기 유입을 위해 공기주입통로와 연결되는 부분과 공기 배출을 위해 에어셀과 연결되는 부분 사이의 소통로 내부에 형성되는 합성수지 시트 반을 접어 형성되는 V자형 밀봉수단을 포함하는 공기충전형 포장재를 제공한다.Air-filled packaging material of the present invention for achieving the above object is formed by the adhesion of the upper sheet and the lower sheet is divided into at least one air cell to act as a buffer against the external pressure; An air injection passage formed in an upper portion of the air cell by adhesion of the upper sheet and the lower sheet so that air can be injected from the outside; One side is connected to the air injection passage for the air inlet from the air injection passage, the other side is a communication passage formed by the adhesion of the upper sheet and the lower sheet to be connected to the air cell for air discharge to the air cell; And a V-shaped sealing means formed by folding a half of a synthetic resin sheet formed inside a communication path between a part connected to an air injection passage and a part connected to the air cell for air discharge to allow air to enter the air cell. Provide mold packaging.

상기 소통로는 각 에어셀 하나마다 소통로도 하나씩 에어셀 몸체와 평행하게 가설되고 그 상부 공기주입통로를 통하여 공기를 주입하는 공기주입부와 소통로 하단에 에어셀 몸체에 공기를 공급하는 공기배출부가 있는 구조이다.The communication path is constructed in parallel with the air cell body, one for each air cell, and the air injection part for injecting air through the upper air injection path and the air discharge part for supplying air to the air cell body at the bottom of the communication path. to be.

따라서 각 에어셀에 공기를 주입한 후 소통로 공기주입구와 공기배출구 사이에 공기 역류를 방지하는 여러 가지 밀봉수단을 가설할 수 있다. Therefore, after injecting air into each air cell, it is possible to construct various sealing means for preventing air backflow between the air inlet and the air outlet through the communication.

이상과 같은 본 발명에 의하면, 하나의 공기 주입통로를 사용하여 소통로를 통하여 다수의 에어셀에 신속하고 용이하게 공기를 충전시킬 수 있다. 또한, 밀봉수단을 형성하기 위하여 별도의 복잡한 공정을 거칠 필요가 없이 에어셀을 형성하기 위하여 상부시트 및 하부시트를 접착하는 과정에서 동시 밀봉수단을 형성할 수 있으므로 기존의 방법에 비하여 매우 경제적이고 효율적이다.According to the present invention as described above, it is possible to quickly and easily charge air to a plurality of air cells through a communication path using one air injection passage. In addition, since it is possible to form a simultaneous sealing means in the process of bonding the upper sheet and the lower sheet to form an air cell without having to go through a complicated process to form the sealing means is very economical and efficient compared to the conventional method .

또한, 본 발명에 의하면, 밀봉수단이 복수의 에어셀 각각의 밀봉상태를 유지시키게 되므로 어느 일부의 에어셀이 파손되더라도 나머지 에어셀들의 밀봉성에는 영향을 미치지 않아 그 완충적인 포장기능을 지속적으로 유지할 수 있다.In addition, according to the present invention, since the sealing means maintains the sealing state of each of the plurality of air cells, even if some of the air cells are broken, the sealing properties of the other air cells are not affected, and thus the buffer packaging function can be continuously maintained.

나아가, 에어셀의 형상 등을 조절하면, 단순히 평면 형태의 완충용 충전재가 아닌 박스 형태 등 입체적인 형태로 접어서 사용할 수 있기 때문에 사용의 편리성이 현저히 증대되고, 포장에 소요되는 시간을 단축시킬 수 있다. Further, by adjusting the shape of the air cell, it is possible to fold and use in a three-dimensional form, such as a box form, instead of a flat cushioning filler, it is possible to significantly increase the convenience of use, and shorten the time required for packaging.
