Abstract
Abstract A container comprising a body (1) with a lid (2) initially sealingly engaged on the body. The lid is removable from the body to open the container and is replaceable to close the container. The body has a mouth with a strip (10) of annular extent secured to the lid, the body being provided with an annular weakening zone (6) or notch (7) in the vicinity of the strip where the mouth of the container is secured to the lid. The container is separable at the weakening zone to separate a part of the mouth and the lid together with the strip from the body, the weakening zone being positioned radially inwards of the strip and upon rupture of the weakening zone forming a locating surface for replacement of the lid on the body. Upon reclosure of the lid on the body, the locating surface engages a cooperating part (25) to hold the lid securely on the body such as by snap-engagement.
