ABSTRACT:
A lidded container is provided which is intended to deter unauthorized removal of the lid. The container has an out-turned lip of inverted U-section having a circumferential horizontal flange supporting an upright retention portion with a retaining bead. The lid has a rim portion which is also of inverted U-section, the web of the U having a formation engaging a complementary formation on the lip of the container to provide location and sealing connection between the lid and container, and the outer limb being outwardly cranked and forming a depending skirt having a retaining formation which interlocks with the retaining formation.
Part of the flange is extended to form a tab which is removable at a line of weakening to facilitate separation of the lid and container. Removal of the tab indicates that the container has been opened or at least that it has been tampered with.
