Abstract:
1. A container/lid combination comprising: a container having an open top end, a closed bottom end, and a side wall having an exterior surface extending from said open top end to said closed bottom end, said side wall being circular in cross-section and increasing in diameter with increasing distance from said bottom end, a plurality of first screw thread means on said exterior surface of said side wall adjacent to said open end, a peripheral flange formed integral with and projecting radially outward from said exterior surface below and spaced from said first screw thread means, and a tab comprising a section of said flange and demarcated by two mutually spaced radially-extending tab-tear grooves in said flange, said tab having an upper side facing in the direction of said first screw means and characterized by a first set of upwardly projecting teeth of saw-tooth shape extending in series between said grooves, said grooves having a depth such as to leave thin sections of said flange connected to said tab that are tearable to allow said tab to be bent downward from out of the plane of said flange, and a catch element projecting upwardly from said flange; and a circular lid having a main body section, a rim section formed integral with and surrounding said main body section, said rim section having a depending skirt at its periphery, said skirt having an internal surface and a bottom edge, said skirt being sized to surround said side wall at the top end of said container, a plurality of second screw thread means on said internal surface of said skirt, said second screw thread means being adapted to make a screw connection with said first screw thread means whereby said lid may be screwed onto said container, multiple sets of teeth projecting downwardly from said bottom edge, each set of said multiple sets of teeth comprising a plurality of like teeth arranged in series along said bottom edge, said multiple sets being spaced from one another along said bottom edge, the teeth of said multiple sets of teeth being shaped to mesh with the teeth of said first set of teeth when said lid is screwed onto said container, said multiple sets of teeth being located so that when said lid is attached to said container by a screwing action involving engagement of said first and second screw thread means, one set of said multiple sets of teeth will mesh with said first set of teeth whereby removal of said lid from said container by a reverse screwing action is prohibited by interference of said first set of teeth with one of the multiple sets of teeth on said skirt, said skirt also having a plurality of latch lugs formed integral with and projecting down from said bottom edge, said latch members being uniformly spaced circumferentially along said bottom edge in alternating relation with said plurality of sets of teeth, said catch element and said latch lugs being located so that when said lid is attached to said container by said screwing action, one of said latch lugs will be in a position relative to said catch element whereby removal of said lid by a reverse screwing action will be prohibited by interference of said one latch lug by said catch element.
