Description

Multi-structure airtight zipper {MULTI STRUCTURE AIRTIGHT ZIPPER}

Embodiments of the present invention relate to a multi-structure sealing zipper mounted on a container for waterproofing and airtightness.

In general, an airtight zipper is a zipper attached to a container so that liquid or gaseous contents such as seasonings, detergents, and shampoos can be contained in a container (a structure capable of maintaining an accommodation state of the contents) while maintaining airtightness. In particular, since it is important to maintain airtightness in the case of accommodating gas, it is somewhat difficult to introduce or discharge gas into or out of the container. In case of taking out the gas from the container, the gas had to be discharged in the reverse direction through the structure through which the gas was introduced. In the case of a structure in which it is important to maintain airtightness, the inflow of gas is mainly configured easily, but in the case of outflow, it is difficult to outflow through a cumbersome process. made possible. In the case of adopting a zipper to compensate for this point, the gas leakage process is simplified, but it may be difficult to maintain confidentiality when fastening the zipper. That is, the zipper is also required to have binding force capable of withstanding air pressure. Therefore, ease in discharging air again after injecting air into the container, and fastening force of the zipper to maintain the airtight state when the air is in the container are required.

The compression member 300 can be fixed with its end inserted into the chain fixing part 140. This structure also prevents water or air from passing through the first zipper part 100 and the second zipper part 200. do.

Meanwhile, as described above, the chain fixing part 140 is coupled to the ends of the first zipper part 100, the second zipper part 200, the first base member 130 and the second base member 230. Therefore, when the fastening of the first zipper part 100 and the second zipper part 200 is released and spread apart to open the container, the chain fixing part 140 opens the first zipper part 100 and the second zipper part ( 200) is pulled in the direction of opening. The pulled chain fixing part 140 may be partially bent. After being bent, of course, it can be elastically restored. An elastically restored part 142 may be formed in the chain fixing part 140 to facilitate such elastic deformation and elastically restored. Elastic restoring unit 142 is as shown in Figure 2 (b).

Specifically, the elastic restoring part 142 includes an insertion hole 142-1 and an incision 142-2. The cutout 142-2 is the chain fixing part 140 is fixed by the force when a pulling force is generated according to the fastening and separation of the first zipper 100 and the second zipper 200. It is provided for ease of deformation and restoration when elastic deformation occurs. In the case of the insertion hole 142-1, the protrusion of the compression member 300 facilitates the deformation and restoration and at the same time prevents fluid such as water or air from flowing into the vicinity of the cutout 142-2. 320 is provided so that it can be inserted.

Specifically, the insertion hole 142-1 may be formed to correspond to the protrusion 320. For example, it may be a through hole formed with a circular inner diameter, and may be combined with the protrusion 320 formed with an outer diameter greater than or equal to the inner diameter. Here, since the compression member 300 may be formed of a material having elasticity such as silicone or rubber, the outer diameter equal to or greater than the inner diameter may be formed larger than the inner diameter, but if the elastic force is determined within the allowable range, the coupling is possible.
