Abstract
A small flip-top container which can be opened and shut using one hand is closed at one end by a stopper having a skirt which grips the inside of the container resiliently and a rectangular end wall with an aperture which extends for a certain distance from one of the minor sides. The aperture is closeable by a flap which is hinged integrally to the end wall at the inner end of the aperture and is held shut by the snap-engagement of a transverse heel formed on a projection from the free end of the internal surface of the flap in a complementary transverse groove from in the minor wall of the skirt immediately below the outer end of the aperture. In order that the flap can be snapped open and shut without excessive force, the frontal edge of the minor wall of the skirt defining the top of the groove has a central part which projects outwardly relative to its lateral parts, over which the heel must pass. For strength, the internal surface of the flap has two lateral ribs which extend for about a third of its length from its free end.
