The invention relates to a cap for glass bottles comprising a body with skirting with at least three cuts made from the outside to the inside of the body, wherein a core is provided with at least three reinforcement ribs and a first concave region or area that coincides with a second concave region or area is provided on the inside of the body, creating a chamber; and wherein said second concave region is integrated into a second body attached to the first body and wherein said second body comprises a flange having a plurality of cuts, whereas in the lower part thereof, said second body has a threaded area in which a plurality of lips are defined and in which reinforcement spokes are provided contiguously.

Provided is an airtight container for positive pressure beverage that has a cap which is able to improve airtightness. The airtight container for beverage is provided with a beverage container and a cap. The beverage container has a body portion and a flange. The flange is continuous with an upper portion of the body portion and defines an orifice. The cap is attached to the beverage container so as to seal the orifice. The cap has a liner and an exterior body. The liner has a thin liner portion for sealing a lower side portion of the flange and a thick liner portion for sealing an upper side portion of the flange. The exterior body is fixed to the flange so as to cover the liner from an outer side, in order to seal the orifice together with the liner. The exterior body presses the thin liner portion against the lower side portion of the flange and brings the thin liner portion in close contact therewith.

A reduced gauged crown for a container opening includes a corrugated panel portion such that the corrugation strengthens the crown material and allows less material to be used for the crown than would be used for an uncorrugated bottle cap.
