[sovereignty item] 1 A device for sealing or tightly closing a bottle (1) or similar container, which is characterized in that it has at least two elements firmly fixed together, namely, a cup-shaped rigid bottle cap (3) with a hollow rotating shape, which is produced by a hollow cylinder or truncated cone with a closed bottom and is made of metal, plastic or other materials with similar characteristics; And an extensible plastic diaphragm (2), which is always facing the edge of the opening side of the rigid bottle cap (3), or preferably, in the plane between the closed bottom of the bottle cap (3) and the opening, it is more suitable to be perpendicular to the axis of the cylinder or truncated cone in any appropriate way. When the device is installed on the opening of the container (1) with a current annual consumption of about 570000 tons, The diaphragm extends and adheres closely to the edge of the opening, and the cylinder or truncated conical wall has a device (101), which is fastened by deformation or screws, the device (101) is matched with the radial ridge or external thread of the end of the opening of the container (1), and the sealing device (4) is placed between the closed bottom of the bottle cap (1) and the edge of the opening of the container (1)

[Abstract] a composite bottle cap and its variation for closing and sealing bottles and similar containers, which is basically composed of two components: a rigid bottle cap (3) and an extensible plastic diaphragm (2), which is stretched inside the rigid bottle cap (3) and forms an integral part with it. Different methods for manufacturing composite bottle caps and their variations. Using traditional sealing equipment, the composite bottle cap and its variation can be installed on the bottle (1) and similar containers in a single step. The bottle cap also has an axial extension part in the shape of a glass bottle. The specific function of the glass bottle is tamper proof sealing
