Plastic bag

제1도는 본 고안의 상면 사시도.1 is a top perspective view of the present invention.

제2도는 본 고안의 저면 사시도.2 is a bottom perspective view of the present invention.

제3도는 제2도의 종단면도.3 is a longitudinal sectional view of FIG.

제4도는 종래의 합성수지포대 사시도.4 is a perspective view of a conventional synthetic resin bag.

본 고안은 합성수지 필름 튜우브로 제품한 곡물, 비료 포장용 합성수지포대의 상면과 저면을 봉함에 있어서 튜우브형 포대 본체 전후면 필름 자체로서 접어서 그 중첩부를 용착 하므로서 견고성과 제작의 용이성을 기하도록한 것이다.The present invention is to seal the top and bottom of the synthetic resin bag for packaging grains, fertilizer packaging made of a synthetic resin film tubing as the tubing bag body front and rear film itself and to weld the overlapping portion to ensure the robustness and ease of manufacture.

종래에는 합성수지필름 튜우브로 곡물, 비료등을 넣을 포대의 저면과 상면을 봉함에 있어서 제4도에 예시한 바와 같이 별개의 필름편(9)을 필름튜우브(7)의 상하 양연부(8)에 대고 그 주연부를 용착부(10)로서 용착하였기 때문에 포대의 상하면 언저리에 두장의 필름 절단부가 노출되어 거치장스럽고 다른 물체에 걸리든가 접촉되어 용착부가 훼손되며 제작 과정이 복잡한 동의 결점이 있으므로 본 고안은 이러한 종래의 제품을 지양하여 합성수지필름를 튜우브 본체의 상하단 자체로서 포대의 상면과 저면을 접어서 형성한 다음 용착한 것으로서 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Conventionally, as shown in FIG. 4, a separate film piece 9 is attached to the upper and lower edges of the film tube 7 by sealing the bottom and the upper surface of the bag to which grain, fertilizer, etc. are put into the synthetic film tube. Since the periphery of the film was welded to the welded portion 10, two film cutting portions were exposed on the upper and lower sides of the bag, and thus the mounting portion was damaged by contact with other objects, and the welded portions were damaged. Avoiding such a conventional product is formed by folding the top and bottom of the bag as the upper and lower ends of the tub body itself, then welded as described above in detail based on the accompanying drawings.

합성수지필름 튜우브로 형성한 포대본체(1)의 상하 부위를 장방형 상자의 상하면 형으로 접어서 상면부(2)및 저면부(2')를 각기 형성하여 상면 및 저면의 중앙 부위에서 겹쳐지게 하고 그 양편은 삼각형 절첩부(3)로 접은 다음 중첩된 부위를 두줄의 용착부(4)로서 용착하고 양연부의 삼각형 절첩부(3)는 삼각형 용착부(5)로서 용착 하였다.The upper and lower parts of the bag main body 1 formed of a synthetic film tube are folded into upper and lower shapes of a rectangular box to form upper and lower parts 2 and bottom parts 2 ', respectively, so that the upper and lower parts are overlapped at the center and upper parts of the lower and lower parts. The silver was folded into a triangular fold (3), and then the overlapped portions were welded as two rows of welds (4), and the triangular folds (3) of both edges were welded as triangular welds (5).

미설명 도면부호(6)은 개구부이다.Unexplained reference numeral 6 is an opening.

이와 같이된 본 고안은 포대본체(1)와 전후좌우 주면의 필름을 그대로 연속시켜 상면과 저면을 형성 하였기 때문에 상면과 저면의 언저리가 거침없이 매끈하고 용착부는 저면과 상면의 중심부에 두줄로 형성되어 견고성을 갖게됨과 아울러 제품이 용이하며 삼각형 절첩부는 상면과 저면의 전후폭을 정확히 구분하게 되여 상자형상으로 형성하는 포대의 규격이 정확한 장점등을 구비한 것이다.The present invention as described above formed the upper surface and the bottom surface by continuing the film of the main body (1) and the front, rear, left and right as it is, so that the top and bottom edges are smooth and the weld is formed in two lines at the center of the bottom and the upper surface. In addition to having robustness, the product is easy to use, and the triangular folded portion accurately distinguishes the front and rear widths of the top and bottom surfaces, and thus, the size of the bag formed in a box shape is provided with accurate advantages.

Claims

As shown in the figure, the upper and lower portions of the synthetic film tubular bag main body 1 are folded to form an upper surface portion 2 and a lower surface portion 2 ', respectively, so that the upper and lower portions overlap each other at the center portions of the upper and lower surfaces, and both sides thereof are triangular sections. A synthetic resin bag, characterized in that it is folded into a patch (3), and then the overlapping portion of the central portion is welded as two rows of welds (4) and the triangle folded portions (3) are welded as the triangle welds (5).
