Abstract
A container closure having a skirt portion provided with an inwardly rolled, continuous, reinforcing bead on the lower edge thereof and engageable with locking projections or threads provided on the container neck portion.
Claims8
A container closure comprising a top wall, a continuous skirt portion depending from the perimeter of said top wall, a continuous reinforcing bead provided on the lower end of said skirt portion adapted to engage interrupted thread portions on a container, said reinforcing bead being of uniform thickness throughout its extent, a portion of said closure having a radial dimension greater than the corresponding radial dimension of the container thread portions, and another portion of said closure having a radial dimension less than the corresponding radial dimension of the container thread portions, whereby when applying the closure to the container the portion of the closure having the greater radial dimension is aligned with the thread portions to thereby position said portion radially outwardly from said threads, and by rotating said closure, the portion of the bead at the shorter radial dimension of the closure is caused to underlie and engage the container threads thereby tightening the closure on the container.
