Disclosed is a metal bottle seal that is disposed on the curl of the metal bottle. The bottle seal may be held in place by crimping of the curl. In addition, adhesive may be used to hold the bottle seal on the curl. Adhesives can be used that fill discontinuities that may exist in the curl as a result of substantial drawing and ironing of the metal. Further, the metal bottle seal can be made of a material or laminated with a material that is soft enough to fill the discontinuities. The seal can be preformed as a continuous annulus for easy application to the top of the metal bottle. The metal bottle seal can also be used in conjunction with a cap seal to ensure an adequate and reliable seal.

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.

A closure made of metal or plastic for a container for accommodating beverages or food has a mouth opening which is to be closed by the container closure. The container closure has a sealing insert which is arranged such that it closes the mouth opening with sealing action when the container closure is fitted on the container. The container closure, including the sealing insert, does not contain any halogen-containing material, and the sealing insert comprises at least two different polymers, of which at least one is a barrier polymer with a Shore D hardness of at most 40 and oxygen permeability of at most 1000 cm.sup.3.Math.100 m/m.sup.2.Math.d.Math.bar and, without the Shore D hardness being limited, with oxygen permeability of at most 10 cm.sup.3.Math.100 m/m.sup.2.Math.d.Math.bar.

Provided are a steel sheet, having sufficient strength and formability regardless of reduction of thickness, for crown caps; a method for manufacturing the same; and a crown cap. The steel sheet for crown caps has a composition containing C: 0.0010% to less than 0.0050%, Si: 0.10% or less, Mn: 0.05% to less than 0.50%, P: 0.050% or less, S: 0.050% or less, Al: more than 0.002% to less than 0.070%, N: less than 0.0040%, and B: 0.0005% to 0.0020% on a mass basis, the balance being Fe and inevitable impurities, and also has a yield strength of 500 MPa or more in a rolling direction, an average Lankford value (r) of 1.1 or more, and an in-plane anisotropy (r) of Lankford value of 0.3 to 0.3.

Bottles with inwardly curled upper portions at the bottle opening and methods and tooling for producing such bottles. The inwardly curled upper portions impart compressive stresses into the bottle material and can reduce a likelihood of material splitting because the upper portion may not be stretched to a larger outer diameter as with outwardly curled upper portions. The inwardly curled upper portions may be formed using rollers with an entry radius positioned near an outside diameter of the bottle opening. The inward curl is formed as the bottle material enters the rollers near an entry face of the rollers, transitions through a work face of the rollers, and exits the roller at an exit face of the rollers. The resulting inward curl meets the edge of the bottle material near the inner surface of the bottle.
