Title:
ツーピース型のオールプラスチックシール
Document Type and Number:
Japanese Patent JP3514760
Kind Code:
B2
Abstract:
A closure device for use with a container having an open neck finish, including an inner cap having a skirt terminating in an open end which engages the outside diameter of the finish. The inner cap is sized to initially engage the finish. The skirt has circumferentially spaced slits extending, which may function as lyophilization ports, which permit the inner cap to expand upon an axial closing force and engage the bottom of the finish. A liner is positioned in the inner cap proximate the closed end and is compressed against the finish when the cap is moved to alignment with the bottom of the finish. An outer cap is locked on to the inner cap in pre-assembly which then encloses the inner cap after complete assembly to seal and compress the liner between the finish and the inside face of the inner cap. In a preferred embodiment, an inwardly facing ridge is located on the inside of the inner cap to engage the liner by a distance sufficient to permit the liner to seal to the finish over the maximum variation of dimensions for the liner and for the crown on the finish.
