Abstract: A product container which is suitable for retaining flowable type materials and which comprises a container portion and a removable closure portion, both of which are formed from a semi-rigid thermoplastics material. The container portion has a marginal lip which incorporates an inwardly directed bead which defines an opening to the container. The closure has a central region which locates within the container opening and an inverted U-shaped rim portion which engages the lip of the container. The rim portion of the closure includes an inner skirt which locates within the lip of the container, which incorporates an outwardly projecting ledge which engages with an undercut below the container bead, and which flares downwardly and inwardly to merge with the central portion of the closure.

Abstract: A plastics material closure for attachment to the rim of a container.The closure has a central well, an inverted first channel which borders the well, a non-inverted second channel that borders the first channel and an inverted third channel which borders the second channel and which is configured to seat on a ledge of a container to which the closure is intended to be fitted.Wall portions of the first channel are interconnected so as to provide the closure with rigidity sufficient to permit the stacking of closure-fitted containers, but the wall portions of the second channel being free to move one relative to the other whereby the closure is provided with a capacity to flex under impact.
