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. The flared portion of the closure skirt incorporates a zone having a section thickness which is less than that of the adjacent portions of the closure, whereby the closure will tend to deform predominently in such zone in the event that the closure is subjected to an impact force, and the zone of reduced section thickness is disposed generally on an imaginary line which extends upwardly and outwardly at an acute angle to the longitudinal axis of the container.
