Document Type and Number:
WIPO Patent Application WO/2016/206253
Kind Code:
A1
Abstract:
Disclosed are a clamping chain and sliding block assembly with different opening and closing pulling forces and a sealing bag, the clamping chain and sliding block assembly with different opening and closing pulling forces comprising a male chain, a female chain and a sliding block (1) opening or closing the clamping chain, wherein the female chain comprises a female chain body (2) and the male chain comprises a male chain body (3) characterized in that several concave pits (4) are provided symmetrically on the female chain body (2) and on the male chain body (3), and the included angle α formed by a face A (5) of the concave pit (4) and the horizontal line of the clamping chain is less than the included angle β formed by a face B (6) of the concave pit and the horizontal line of the clamping chain; and the sliding block (1) comprises a side plate (7), an open triangular block (8) and a closed triangular column (9). Providing concave pits on an outer side or an inner side of the clamping chain and using the amount of resistance between the sliding block and the concave pits to affect the force exerted by a human hand in the process of use determines whether the moving direction of the sliding block is opening or closing the sealing bag so as to better know the usage condition of the sealing bag. When such a sealing bag is applied to industrial automatic production packaging, an automated device can determine whether a sealing bag is in an open or closed state via the exerted force thereby, which improves the efficiency and quality of packaging a finished product.
