The invention provides a glue-on closure for a composite can or the like that affords an original hermetic seal. A tamper-evident tear band allows the closure to be conveniently opened. Separate end wall and sidewall parts of the closure are configured to provide reclosability with a surface-to-surface contact plug fit.

[ We claim:] [1.] A container construction comprising a one-piece injection molded thermoplastic body including an end wall part, a sidewall part and a frangible tear band hermetically joining the end wall and sidewall parts, the tear band being separable from the end wall and sidewall parts when subjected to a manually applied pulling force, the sidewall part providing an aperture for access to the container when the tear band is torn away from the parts and the end wall part is lifted away from the sidewall part, the end wall part being reclosable with the sidewall part by having respective sealing surfaces that are in mutual contact around said aperture when said end wall part is lowered onto the sidewall part, the sealing surfaces including a generally radially extending peripheral flange on one of the sidewall and end wall parts and a peripheral groove on the other of the sidewall and end wall parts for receiving the flange with a sealing interference snap fit, the tear band including two frangible zones substantially thinner than the wall thickness of the main areas of the body, the frangible zones being paced apart axially a distance substantially greater than the distance of their radial spacing whereby the tear band has a relatively high compressive strength.
