Abstract

A wide-necked barrel made of synthetic resin has a removable lid that has a lip-like inner rim axially interfitting into the barrel neck and an edge externally overlapping the barrel neck. The external edge of the lid has spaced extensions that extend obliquely downward and that receive between them projections integrally molded into the barrel neck, so that the upper side of the extensions and the under side of the projections of the barrel neck form a circumferentially extending V-slot that receives a tightening ring. The projections of the barrel neck are trapezoidal as seen in side elevation; and inside the barrel neck, at the location of the spaces between those trapezoidal projections, the material of the barrel neck is compressed into an annular series of supporting beads for the lip-like inner rim of the lid.
