Abstract

A container includes a cover engaged on an open top. A channel and an opening are formed in the cover. A knob is slidably engaged in the channel and includes a tube having a pair of shoulders. A plug has a pair of hooks engaged into the tube and engaged with the shoulders so as to secure the plug to the tube. A spring is biased between the knob and the plug for biasing the knob partially outward of the cover and for forcing the plug against the cover to enclose the orifice. The plug can be made of plastic material instead of metal material.
