Abstract
Tear-off closure caps shaped for distribution at high speed in channels, the caps each comprising two tear-off tongue portions disposed in a flat V-shape in the plane of the rim portion, at the bottom of its skirt portion. The tongue portions have the outer ends slightly bent upwardly, the bends obliging the rim portion of each cap to become engaged under the tongue portions of the cap which precedes it in a distribution channel. The distribution channel includes grooves in the opposed side walls which receive and guide the outer edges of the tongue portions, the outer edges being slightly divergent relative to each other toward their outer ends.
Claims4
A closure cap comprising an annular depending skirt portion having a peripheral rim portion about the bottom thereof, two spaced tongue portions extending rearwardly from and disposed in the plane of the rim portion and forming a V-shaped space therebetween, the inside edges of the two tongue portions forming, with the edge of the rim portion in the space between the two tongue portions, a curvilinear opening wherein the inside edges of the tongue portions are substantially at a tangent to a circle having a diameter equal to the diameter of the skirt portion, while the opposite edges of the tongue portions are generally parallel and spaced apart by a distance generally equal to the diameter of the rim portion, the outer ends of the two tongue portions being curved upwardly along two symmetrical folds to insure engagement of the rim portion of an adjacent cap under the tongue portions.
