Description of the Related Art Cork stoppers are widely used as stoppers for high-grade beverages such as wine stoppers and whiskey stoppers even though synthetic resins have been developed due to their excellent sealing properties for thousands of years as stoppers for beverage containers. in use. In such a cork stopper with a high gas pressure of the contents, for example, a cork stopper for sealing sparkling wine, etc., in order to cope with this high gas pressure, a plurality of natural cork thin plate materials are laminated vertically and horizontally. A block material having an improved gas sealing property is formed by adhering it, and this block material is punched or shaving to obtain a cork stopper having a desired shape.

に優れた圧搾コルク栓を提供することを目的とする。However, as described above, in the structure for forming the cork stopper by forming the block material having a good gas sealing property, steps such as plate formation, adhesion, and further punching process are performed. Since many of them are troublesome and not suitable for mass production, they are disadvantageous in terms of price, and there is a demand for immediate improvement of these drawbacks. Further, in the case of a pressed cork stopper produced by coating adhesive on cork granules and press-molding it, when this is used as a stopper for high pressure gas such as sparkling wine, it is formed by being pressed. Since the central portion of the cork stopper tends to have a low density, there is always a risk of gas leaking from this central portion, and there is a drawback that a highly safe sealing performance cannot be obtained. Although such a drawback can be solved by increasing the density, it is difficult to say that this is a good solution because the cap removal force for removing the cap from the bottle mouth is increased. It is an object of the present invention to overcome such drawbacks and provide a squeezed cork stopper having an excellent elastic sealing property.
