Sealing bag with chuck

Abstract

A sealing bag with a chuck capable of surely increasing an easy-to-unseal property without increasing the size of the chuck and an entire bag and without causing dissolution and flatness at projected parts at the time of bag-making, comprising a bag body (1) having an opening part (1a) at one end, a chuck (10) having a pair of tapes (11a) and (11b) thermally fused near the opening part of the bag body (1) and opposed to each other along the opening part (1a) and a pair of female and male clamping devices (12a) and (12b) formed on the opposed faces of the pair of tapes (11) and disengageably clamped along the opening part (1a) to seal the bag body (1), a pair of projected parts (20a, 20b) formed in a pair of projected lines at the bag body opening side end edge part of the pair of tapes (11a) and (11b) and integrally projected to the inner and outer surface sides of the bag body (1a), wherein the projected parts (20a) and (20b) are positioned on the inside of the opening edge part of the bag body (1) since the pair of tape (11) is thermally fused to the inner surface of the bag body, and the projected parts (20a, 20b) are not thermally fused to the inner surface of the bag body (1).

Description

technical field [0001] The present invention relates to a sealed bag with a clip provided with snap-in clips (fasteners) for opening, closing and sealing the bag near the opening of a bag body formed of a synthetic resin film or the like. [0002] In particular, it relates to a small airtight bag with a chuck suitable for holding medicines, food or miscellaneous goods, by providing a protrusion integrally protruding from the inner surface side and the outer surface side of the bag main body at the tape end edge of the chuck At the same time, by disposing the raised portion on the inner side not exposed from the opening of the bag main body without being welded to the side of the bag, the enlargement of the chuck or the bag main body is avoided, and in addition, it does not occur when the bag is manufactured. Melting, flattening of the raised portion, and can reliably improve the easy-openability of the pouch. Background technique [0003] Generally, in a known airtight bag ...

Problems solved by technology

[0017] However, only the clips are provided on the inner surface of the bag main body and convex lines are formed, and the convex lines can only protrude from the inner surface side of the bag, which cannot be said to be sufficient as an anti-slip device for fingers.

In addition, when the clips are welded to the bag body, the ridges etc. provided on the inner surface of the bag will melt and become flat together with the clips, and may not function as a finger anti-slip device.

Furthermore, in order to prevent the melting and flattening of such ridges, for example, although it is considered to form the ridges with a predetermined length so as to have a certain length even if they are melted, only the ridges are lengthened, and when the bag is manufactured, The ribs tend to fall down and are difficult to manufacture, and at the same time, since the ribs protrude long inside the bag, it is difficult for fingers to enter the opening of the bag, and the opening and closing performance of the bag is impaired
