  • Patent number: 4790448
    Abstract: A container and lid assembly including a container having a cylindrical side wall and top rim, and a lid having an inverted U-shaped rim and depending skirt portion which is snapped over the rim of the container wall to form a sealing closure therewith. An annular ridge projects inwardly from the inner surface of the skirt portion so as to ride over and engage under the upper bead of the container wall, thereby creating single point interference fits between the container and lid. The outer edge of a first shoulder engages a score line on the inner surface of the skirt portion defining a bi-directional tear strip. The distal end of the tear strip closely confronts a second shoulder when the container is originally sealed. The inside wall of the lid prevents the container from being deformed or collapsing when opened.
