Description

Fastener-type zipper structure with improved sealing structure {Improved sealing structure having zipper bag}

The present invention relates to a fastener-type zipper bag having an improved sealing structure, and more particularly, to seal the inlet of the sealing member through a zipper formed in the opening of the sealing member, and keeps the objects stored in the sealing member in a sealed state. The present invention relates to a fastener type zipper bag having an improved sealing structure.

In general, fasteners, which are used to freely join and separate two separate parts, are useful around us, and the commonly used zippers come with snap fasteners called snap buttons. Velcro, which is widely used in clothing, also known as `` sticky '', is widely used in hat size adjustment bands and bags, and is used by installing a fastener at an open position for free opening and closing at a vinyl inlet. Doing.

On the other hand, the zipper bag of the plastic bag is formed in the form of a zipper portion consisting of a pair of zipper member in the inlet portion of the sealing member, the inner wall of the opposing zipper member is formed to correspond to the linear projection and the linear groove, the linear The linear projection is elastically pressurized in the lateral direction to seal the inlet of the sealing member.

In recent years, a fastener is provided in the zipper to allow the fastener to be opened and closed by changing the elastic indentation state between the linear groove and the linear protrusion by the fastener, thereby ensuring convenience and quickness due to the opening and closing of the zipper.

However, the zipper bag is to ensure a sealing force through the linear groove and the linear protrusion, but the linear groove and the linear protrusion may be easily separated when the bending occurs by the external force due to the lack of flexibility.

In addition, when the sealing member is compressed to increase the internal pressure of the sealing member or move to one side by an external force, and the fastener closing the zipper part is randomly moved to the other side, the coupling state of the linear groove and the linear protrusion is dismantled and the inlet of the sealing member is released. The phenomenon in which the arbitrarily open portions can be caused.

Therefore, the conventional fastener-type zipper bag secures the convenience of using the zipper to be easily opened and closed through the fastener, but the fastener is easily released to the other side by the internal pressure or external interference of the sealing member while the zipper is closed. It has a limit that is difficult to ensure stable sealing.
