Description

터짐방지수단을 구비한 파우치{a pouch}Pouches with anti-burst means {a pouch}

본 발명은 각종 세제나 액상의 물질을 수용하고 있는 파우치에 관한 것으로, 특히 파우치의 배출구 형성시 균일한 접착면적을 형성하여 안정성을 확보하는 한편 순간적인 압력에 의한 터짐발생을 최소화하고자 하는 것이다.The present invention relates to a pouch containing various detergents or liquid substances, in particular to form a uniform adhesive area when forming the outlet of the pouch to ensure stability while minimizing the bursting of the instantaneous pressure.

일반적으로 파우치는 리필의 사용을 위하여 별도의 사출성형되어진 배출구를 가진 비닐봉지로서, 액상의 세제 등을 담아 놓은 것이다.Generally, a pouch is a plastic bag having a separate injection molded outlet for use of a refill, and contains a liquid detergent.

그리고 이러한 파우치는 통상 인쇄가 용이한 PET필름과 배출구를 시트에 열융착하기 위한 PE필름으로 이루어져 있고, 이때 PE재질로 이루어진 배출구와 PE필름이 열 융착되면서 배출마개가 장착되어 있는 배출구가 비닐봉지 시트에 설치되어 지는 것이다.And the pouch is usually composed of a PET film for easy printing and PE film for heat-sealing the outlet to the sheet, wherein the outlet made of PE material and the PE film is heat-sealed, the outlet is equipped with a discharge stopper plastic bag sheet It will be installed in.

그러나 상기와 같은 파우치는 융착라인을 두껍게 형성하여야 하기 때문에 작업속도가 늦어질 수 밖에 없고, 특히 열 융착시 융착된 PE필름의 일부분이 융착된 배출구의 살과 날개에 의해 접착면적 밖으로 밀려나가게 된다.However, the pouch as described above has to be thickened to form a fusion line, the operation speed is inevitably slowed down, and in particular, a portion of the fused PE film is pushed out of the bonding area by the flesh and wings of the fused outlet.

따라서 이 밀려나간 융착액에 의해 균일한 접착면적을 형성하지 못하게 되어, 접착력이 약한 부위가 순간적인 압력에 의해 터짐이 발생할 수도 있게 되는 것 이다.Therefore, it is impossible to form a uniform adhesive area by the extruded fusion solution, so that the weak adhesive force may be caused by the bursting of instantaneous pressure.

즉, 파우치 안쪽에는 액상의 물질이 채워져 있어, 이동중에 가벼운 충격에 의해서도 액상의 물질이 유동할 수 밖에 없고, 이로 인해 순간적인 압력에 의해 터짐이 발생할 수도 있게 되는 것이다.That is, the inside of the pouch is filled with a liquid material, the liquid material is forced to flow even by a light impact during the movement, which may cause bursting by the instantaneous pressure.

따라서 본 발명은 PE재질로 이루어진 배출구와 PE필름을 열 융착할 때에, 배출구의 살과 날개에 의해 접착면적 밖으로 밀려나가게 되는 융착액을 최소화하고,동시에 밀려난 융착액을 이용하여 균일한 접착면적을 형성토록 함으로, 순간적인 압력에 의해 터짐이 발생하는 문제를 해소하고자 하는 것이다.Therefore, the present invention minimizes the fusion liquid which is pushed out of the adhesion area by the flesh and wings of the outlet when heat-sealing PE outlet and PE film made of PE material, and at the same time by using the fusion solution pushed out to achieve a uniform adhesion area By forming, it is intended to solve the problem that the burst occurs by the instantaneous pressure.

즉, 이를 위해 본 발명은 실링의 안전성을 확보하기 위하여 배출구의 경사면에 돌출면을 돌출시켜 형성하고 동시에 상기 돌출면의 상단과 하단에 실링홈과 돌출살을 이어서 형성하며 상기 실링면의 좌측과 우측으로 연장되어 있는 날개와 경사면의 일부분을 함께 융착라인 안쪽으로 융착되어지도록 되어 있는 것을 특징으로 하는 것이다.That is, the present invention for this purpose is formed by protruding the protruding surface on the inclined surface of the discharge port in order to ensure the safety of the sealing and at the same time forming a sealing groove and the protruding bar at the top and bottom of the protruding surface and the left and right of the sealing surface A portion of the wing and the inclined surface extending to be fused together to be fused into the inner fusion line.

본 발명은 경사면의 둘출면을 넓게 형성함에 따라 실링의 안전성을 확보할 수 있고, 동시에 돌출면과 날개 밖으로 밀려져 나온 융착액이 확보된 공간에 융착되어지도록 하여 최대한 균일한 접착력을 확보할 수 있도록 되어 있다는 특징을 가지고 있다.The present invention can secure the safety of the sealing by forming the bulge of the inclined surface wide, and at the same time to ensure that the fusion liquid pushed out of the protruding surface and the wing is fused in the secured space to ensure the most uniform adhesive force Has the characteristic of being.
