본 고안은 비닐 포대의 구부를 형성함에 있어서, 포대의 개구부일측에 단장으로된 직사각형의 구부용비닐지를 내입하되, 하측은 포대의 개구부 한쪽면과 2겹 횡융착하고 상측은 포대의 개구부에 연하여 구부용비닐지의 2/3지점까지는 다른 쪽면과 2중 융착하며 잔여 1/3지점은 포대의 양측면과 3겹횡융착함과 동시 구부용 비닐지의 측면도 3겹 종융착함으로서 봉합상태가 양호할 뿐만 아니라 취급시 내용물의 누출이 전혀없는 ''L'' 자형의 통로를 갖는 구부를 간편용이하게 제조할 수 있게한 것이다.In the present invention, in forming the bend of the vinyl bag, a rectangular bent plastic sheet having a short length is inserted into one side of the opening of the bag. Up to 2/3 of the plastic sheet is double welded to the other side, and the remaining 1/3 of the bag is triple laminated to both sides of the bag and 3 sides of the plastic sheet to bend simultaneously. This makes it easy to make a bend with a `` L '' shaped passageway with no leakage of contents.
일반적으로비닐포대의 구부는 내용물을 충입하면 포대 내측에 위치하는 구부의 하단이 밀착되어 자연 폐쇄되므로 이를 이용하여서 종래에는 원통형튜브를 착설하거나 또는 ''L'' 자형의 튜브를 융착하여된 것들이 알려진 바 있다(일본 실용신안 소 39-28488). 그러나 이들은 튜브와 포대의 융착부위는 4겹이고, 포대의 개구부는 2겹이기 때문에 기계로 자동적으로 융착하는데는 어려움이 많았다. 즉, 4겹 융착부위에 융착강도를 맞추어 놓으면 2겹 융착부위는 녹게되거나 또는 두께가 엷어지고 2겹융착 강도에 맞추며 4겹 융착부위는 융착이 미흡하여 융착 부위가 쉽게 훼손되어 내용물이 유출되는 사례가 다대하였을 뿐만 아니라 작업 과정이 복잡하여 대량생산에 많은 지장을 초래 하였다.Generally, the bend of the vinyl bag is filled with the contents, and the bottom of the bevel located inside the bag is in close contact with each other, thereby naturally closing. By using this, conventionally, a cylindrical tube or a `` L '' shaped tube is known to be known. (Japanese Utility Model Small 39-28488). However, they had difficulty in automatically fusion with the machine because the fusion area of the tube and the bag was four layers and the opening of the bag was two layers. In other words, if the welding strength is adjusted to the 4-ply fusion site, the 2-ply fusion site will melt or become thinner and match the strength of the 2-ply fusion zone. Not only was it huge, but the work process was complicated, causing a lot of disruptions to mass production.
본 고안에서는 이와 같은 종래의 결점을 보완코져 안출한 것으로서 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In the present invention, as a complement to the above-mentioned conventional drawbacks as described in detail by the accompanying drawings as follows.
비닐 포대의 구부를 형성함에 있어서 통상의 비닐포대(1) 개구부(2) 일측에 단장으로된 직사각형의 구부용 비닐지(3)를 내입하되 구부용 비닐지(3) 하측은 포대(1)의 일측면(A)과 2겹융착(4)하고 상측은 횡방향으로 2/3지점까지는 포대(1)의 다른 일측면(B)과 2겹 융착(5)하여 잔여 1/3지점과 종방향으로는 포대(1)의 양측면과 3겹융착(6)(6')하여 ''L'' 자형의 통로를 갖는 구부를 형성하여서 된 것이다.In forming the bag of the vinyl bag, a rectangular plastic sheet for bending (3) is cut into one side of the opening (2) of the ordinary bag (1), and the lower part of the plastic bag (3) is inserted into the bag of the bag (1). One side (A) and two-ply fusion (4), and the upper side is two-ply fusion (5) with the other one side (B) of the bag (1) up to two-thirds in the transverse direction. It is to form a sphere having a `` L '' shaped passage by three-ply fusion (6) (6 ') with both sides of the bag (1).
이와 같이된 본 고안은 구부용 비닐지(3)가 튜브형이 아니고 단장으로 된 직사각형의 비닐지이기 때문에 포대(1)와의 융착면이 2겹 또는 3겹에 불과하며 융착 작업을 기계적으로 균일하게 대량 생산할수 있으며 융착 상태가 양호하여 사용도중 구부의 융착 부위가 파손되어 내용물이 유출되는 사례가 전혀 없게 되는데, 사용시에 있어, 본 고안을 제3도에 표시한 바와 같이, 구부의 외측 모서리를 내측으로 접어 넣으면 횡방향으로 직선상태로 개방되어서 충전물을 손쉽게 집어 넣을 수 있게 되고 또, 가득 채우게 되면 내용물의 압력으로 모서리 부분은 자동으로 복귀하면서 불환변(不還弁) 상으로 폐쇄되는 것이다.The present invention as described above is because the plastic sheet for the bend 3 is not a tubular shape but is a rectangular vinyl paper with a short length, and the fusion surface with the bag 1 is only two or three layers. It can be produced and the welding state is good, so that the fusion site of the sphere is broken during use, so that there is no case of leaking the contents. In use, as shown in FIG. 3, the outer edge of the sphere is inward. When it is folded, it opens in a straight line in the transverse direction, so that the filling can be easily inserted, and when it is full, the corner part is automatically returned to the invariant state by the pressure of the contents.
이상과 같이 본 고안은 구부의 융착 부위가 2겹 또는 3겹으로서 융착 상태가 균일하게 기계적으로 대량생산이 가능하고 ''L''형의 튜브를 별도로 제작 하지 않고 직사각형의 구부용 비닐지(3)를 사용하므로서 제작공정이 간편하면서도 구부의 작용 효과면에서는 종래의 것보다 현저히 향상된 것이다.As described above, the present invention is capable of mass production of mechanically uniformly welded parts with two or three layers of spherical welds, and does not produce `` L '' type tubes separately. By using), the manufacturing process is simple and significantly improved than the conventional one in terms of the effect of the bend.
