Description

Sealed zipper slider and assembly

Technical Field

The utility model relates to a sealed zip fastener slider and subassembly belongs to sealed zip fastener technical field.

Background

The zipper assembly is a sealing device commonly used in daily life of people, it is in the same place through two single chains and slider combination, the slider is including the limiting plate of relative setting and the connecting plate of connecting the limiting plate, be equipped with the branch core on the connecting plate, two single chains set up relatively, respectively be equipped with a toothless couple on the relative face of single chain, when the slider slides to one end along two single chains, press from both sides the toothless couple on two single chains, two single chains will be closed together, and when the slider slides to the opposite direction, divide the core to strut the toothless couple of two single chains, two single chains just can part, thereby form the mouth that can open and shut between two single chains.

The zipper assembly is very convenient to open and close, so that the zipper assembly is widely applied to file bags and freshness protection bags at present. The freshness protection package is generally used for containing food or liquid, if the freshness protection package is not tightly sealed, leakage of the liquid is wasted, and some foods contain moisture, and the moisture in the foods flows out of the freshness protection package to pollute a refrigerator or other foods. In order to prevent the situation, most of the existing freshness protection bags are made of plastic materials with good waterproof performance, but moisture can only be prevented from seeping out of the bag body, but the moisture cannot be prevented from flowing out of the bag opening. But after the arrangement, the non-tooth hooks at the core splitting part cannot be completely closed and sealed, water can flow out from a gap between the core splitting part and the non-tooth hooks, and the zipper cannot prevent the water from flowing out from the bag opening. For better sealing effect of a bag opening, the existing freshness protection package for articles containing liquid generally adopts a double-layer sealing zipper assembly, namely, each single chain is provided with two toothless hooks and an auxiliary rail, the core splitting body of the sliding block is positioned between the auxiliary rail and the first toothless hook, when the freshness protection package is closed, even if the first toothless hook of the two single chains cannot be completely sealed due to the existence of the core splitting body, the core splitting body cannot easily influence the sealing of the second toothless hook, the sealing effect is better theoretically, and the freshness protection package can be used for packaging moisture-containing food and liquid. However, in practical application, the influence of the width of the split core body on the sealing effect of the zipper assembly is relatively large, if the width of the split core body is too large, a second toothless hook can be opened during zipper sealing, so that good sealing cannot be achieved, and the sliding block can be slid only by taking a lot of effort, so that the use is inconvenient; if the width setting that will divide the core is less, the tight power of knot between the toothless couple if do is tight, the width of dividing the core probably is not enough to strut two toothless couples, uses very inconveniently, can't guarantee sealed effect through the tighter of doing between the single chain, moreover when opening and shutting, if not paying attention to the dynamics of pulling the slider, the slider just slipped when the slider slides the tip very likely, leads to the damage of zip fastener, and the freshness protection package can't continue to use. And, because the slider is the injection molding, need the drawing of patterns in the in-process of processing, for the drawing of patterns more fast, the common way is that the side that will divide the core sets up a draft, and the contained angle that divides all sides of core and connecting plate is the obtuse angle promptly, makes things convenient for the mould to deviate from, because the setting of draft, divides the core more to tend to the outward movement when sliding, divides to break away from more easily between core and two single chains. Therefore, there is a need for a containment zipper assembly that ensures the containment effect of the containment bag while providing convenient zipper use.
