Abstract
A resealable container closure including a cap and a tear band formed therewith for engagement with the external wall of the container. A depending flange formed on the underside of the cap engages the internal wall of the container to form a plug seal therewith. Removal of the tear band permits separation of the cap from the container, but re-sealing therewith upon re-engagement of the plug seal with the internal wall of the container.

A closure for a container having a generally circular cross-sectional configuration, the container having an external and an internal surface, said closure comprising, a circular cap having a periphery, an underside and a top side, a band formed integral with the periphery of the cap, the band having an inner-facing surface and being integrally joined to said cap by means of a web at a location to divide said band into upper and lower portions, means formed between the inner-facing surface of the band at a lower portion thereof and the external surface of the container for cooperative engagement therebetween, a depending flange formed along the periphery of the underside of the cap to be in cooperative engagement with the internal surface of the container, said flange forming a plug seal between the cap and the container when the flange is in engagement with the internal surface of the container, means to separate the band from the cap without disturbing the plug seal, said cap being removable from the container upon separation of the band from the cap but being replaceable upon the container by re-engaging the flange with the internal surface of the container to re-establish the plug seal therebetween;
- and wherein said means to separate the band from the cap without disturbing the plug seal comprises a tear tab formed on a portion of the band and extending over the cap.
A closure for a container having a generally circular cross-sectional configuration, the container having an open top and a closed bottom and external and internal surfaces, said closure comprising a cap having an upstanding circular wall with upper, medial and lower portions and external and internal surfaces, a circular plate secured to a lower portion of the inner surface of said circular wall in a fluid tight connection, the external diameter of the lower portion of said circular wall being slightly greater than the internal diameter of said container open top so as to form a plug seal therewith, a web extending circumferentially around an external surface of a medial portion of said circular wall, a circular band having upper, medial and lower portions with external and internal surfaces, said band secured to said web at an internal surface of a medial band portion to lie in closely spaced relationship with said circular wall, interengaging means on an inner surface of a lower band portion and on the external surface of said container for securing said closure to said container, and means to separate the band from said circular wall, said means including a circumferential score line on said web and a tear tab connected to a portion of said band.
