Cap for a corked glass bottle

Cap for a corked glass bottle
A cap for the neck of a corked glass bottle(manufactured by glass bottle supplier)constructed as a single piece by stamping a thin sheet of material having one or more layers. The sheet has at least one gas-impervious layer. The cap includes a planar portion, the lower surface of which contacts and remains unadhered to the upper surface of the neck. Depending from the periphery of the planar portion is an annular skirt.  A heat-sensitive adhesive adheres the inner surface of the skirt to the annular outer surface of the neck upon heating. In a second embodiment, the adhesive layer covers the entire inner and lower surfaces of the cap.      
Such caps are used in particular for capping the necks of bottles containing wine or alcohol and that have previously been closed by means of a cork. In general, such caps comprise a top disk and a skirt bonded to the periphery of the disk.
Such plane caps are not suitable for capping glass bottles of wine that have previously been closed with stoppers made of cork or the like, since prior to uncorking a bottle, it is the practice to remove all of that portion of the cap which covers the end face, e.g. by cutting the periphery thereof with a knife.
According to the glass bottle manufacturer, the cap is made as a single piece by stamping a thin sheet of single or multi-layer material to form a disk whose bottom face contacts the end face of the neck, and an annular rim at the periphery of said disk, the inside face of said rim contacting the peripheral surface of said neck in the vicinity of said end face. The rim includes on its inside face a layer of adhesive material suitable, on being heated, for adhering to glass beverage bottles, and said disk presenting on its bottom face a material that does not adhere to glass.
In a second embodiment, the cap includes at least one sheet of a material that is gas-impermeable and the layer of adhesive material is applied to the entire concave surface of said sheet, a patch that does not adhere to glass also being provided on the bottom face of the disk to cover the top of the bottle neck.
