Abstract of the Disclosure A snap-type cap for sealing against escape of gases through an opening in an end closure of a container having contents therein which dissociate a gas therefrom. The cap includes a seal portion to engage with a sealing lip around the opening in the container end to provide an initial low pressure seal and a second high pressure seal as progressively higher pressures within the container exceed the sealing limit of the initial low pressure seal. The cap may further include an opening portion adapted for contacting an opening panel in the container end and effecting an opening in the container by applying pressure against the opening panel through the opening portion. An improved easy open container end having a smooth sealing lip for cooperating with the cap for resealing and a method of making such an end are also disclosed.
