ABSTRACT:
A removeable plastic plug for a container having an annular outlet opening includes a unitary outer annular wall which is arranged with an annular upper lip portion, an annular lower rib portion, and an enclosing body portion which extends between the upper lip portion and the lower rib portion. The enclosing body portion defines a hollow interior which is sealed across by a closing diaphragm arranged in unitary construction with the enclosing body portion. The closing diaphragm includes an upwardly inclined portion to which a pull ring is attached. The outer annular wall further defines an annular receiving channel and a retention bead whereby the edge defining the outlet opening snaps into said annular receiving channel with the retention bead positioned on the underside of the defining edge. The lower rib portion is segmented by three equally spaced inverted V-shaped notches which are centered relative to the pull ring and which are disposed adjacent to the upwardly inclined portion. By means of the described construction, the plastic plug is able to be easily removed from the outlet opening by use of the pull ring.
