Title
(EN) Multipart Plastic Closure
Abstract
(EN)

A multi-part plastic closure that accommodates an increased inner pressure in the receptacle on which the closure is attached, while avoiding deformations which compromise the tightness or sealing of the closure. The corresponding multi-part plastic closure includes a lower part having a first region with a lateral surface, with an inner thread for screwing onto a receptacle, and which is closed to the top by a pour-out mouth or spout. The pour-out mouth or spout includes a top surface or covering area which is reduced as an annular sealing surface and is reinforced by stiffening. A centric pour-out opening or central spout is provided with a sealing, and a sealing plug or peg which is integrally formed or molded on the lower side or bottom face of a screw cap capable of being put on, moves into the central pour-out opening or spout. One or more drinking openings are molded or formed in the region of the lateral wall of the screw cap and the sealing plug or peg in the top surface. The multi-part plastic closure configured in such a manner is also capable of sealing relatively high inner pressures in the receptacle.
