[0006] As a preferred technical solution of the utility model, the middle part of the top of the stretch film is concave inward, and the depth of the concave is matched with the thickness of the protective film, and the size of the bottom film is matched with the inner diameter of the adsorption ring.
[0007] As a preferred technical solution of the utility model, the inner diameter of the bottom ring is larger than the inner diameter of the adsorption ring, and the cross-section of the bottom ring is L-shaped.
[0008] As a preferred technical solution of the utility model, the protective film, the stretch film and the base film are bonded and fixed to each other by bonding.
[0009] As a preferred technical solution of the utility model, the inner side wall of the adsorption ring is bonded and fixed to the outer side walls of the protective film, the stretch film and the base film.
[0010] As a preferred technical solution of the present utility model, the adsorption ring, the bottom ring and the plug are all made of soft plastic material.
[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:
[0012] 1. In this device, by setting up three sets of combined membrane structures, the user can use the honeycomb groove structure opened in the middle stretching membrane structure to facilitate the outward stretching of the device and seal it with the bottle mouth of the glass product. The protective film and bottom film structure can strengthen the tensile strength of the middle stretching film to avoid tearing and breakage.
[0013] 2. In this device, through the positioning component, the user can achieve adsorption with the bottom part of the glass bottle mouth through the adsorption ring-bottom ring-plug structure, and the cross-section of the bottom ring is an L-shaped structure, so through its soft structural characteristics, it can be adsorbed with the glass product to achieve the auxiliary fixed connection effect of the membrane component, avoiding the falling off of the existing membrane structure.
