Packaging bag capable of being self-sealed and opened repeatedly

Abstract

The invention discloses a packaging bag capable of being self-sealed and opened repeatedly. The packaging bag comprises a bag body and a suction nozzle area which are connected and communicate with each other. A plurality of easy-to-tear openings and self-sealing strips are arranged in the suction nozzle area at intervals. According to the packaging bag, due to the structural characteristics thatthe multiple pairs of easy-to-tear openings and the self-sealing strips are arranged in the suction nozzle area at intervals, direct drinking and repeated opening of liquid drinks or content materialscan be effectively achieved by combining the width change of the bag body of the packaging bag without additionally arranging a bottle cap and other accessory structures. According to the packaging bag, when drinks in the packaging bag are not drunk up at a time, the packaging bag can be sealed again by the self-sealing strip, and when the packaging bag needs to be used again, the packaging bag only needs to be torn off along the easy-to-tear opening adjacent to the self-sealing strip. If the liquid beverage is still not drunk up again, the adjacent self-sealing strips can be used for sealingagain, so that multiple times of opening and effective sealing after opening can be achieved.

Description

technical field [0001] The invention relates to a reusable packaging bag, in particular to a self-sealing and multiple-openable direct-drinking liquid packaging bag, especially suitable for liquids or other materials that need to be opened multiple times after the packaging is opened. Such bags. Background technique [0002] After tearing the packaging bag when the traditional packaging bag for holding liquid beverages is used, the liquid in the packaging bag must be drunk once. If you can't drink it all at once, if the remaining liquid drink in the packaging bag cannot be well sealed, it is very difficult to preserve and keep fresh. In addition, packaging bags used to hold liquid drinks are often designed with a self-sealing strip structure, which is used to re-seal the packaging bag itself after drinking. However, the self-sealing strip of this type of liquid packaging bag is often not easy to open, and after finally opening, the liquid drink in the packaging bag is easi...

Problems solved by technology

[0004] However, the above-mentioned existing patent application needs to set some sealing strips and self-adhesive protective films on the small packaging bag, and also needs to set some easy-to-tear lines between the sealing strips, which not only takes up a lot of space due to redundant structure , and because the number of openings of the packaging bag depends on the number of easy-to-tear lines, the number of openings of this type of plastic packaging bag is strictly limited

Furthermore, although the above-mentioned prior art can reseal and store the unused remaining materials after the plastic bag containing the material is opened and used, so as to achieve the purpose of reusing and sealing the plastic bag, it can only be used for solid material storage. It cannot be used for packaging of liquid items and multiple openings

In addition, the above-mentioned existing technology has a simple design for the opening and retrieving link, and the reuse rate is low. It is also easy to tear the easy-to-tear thread and the self-adhesive protective film accidentally, resulting in the result that the packaging bag cannot be effectively sealed at all.
