ONE-PIECE DISPENSING CLOSURE

摘要

A one-piece dispensing closure has an annular skirt on the inner side of which there are threads which co-operate with threads on a container neck for retaining the closure on the container. The closure has a disc-like top in which there is a dispensing opening and a lid for the opening which is an integral part of the closure and is hinged to the closure top at one edge thereof. The lid has an integral plug adapted to close the dispensing opening when the lid is swung into closing position overlying the closure top. The closure top and the underside of the lid have co-operating projections, for example, ears and a post, which function to prevent the lid from swinging to closing position when the closure is turned over to position for dispensing content material and which can be manually interengaged for retaining the lid in closing position when desired.
