ABSTRACT:
A plugging device for bottles such as a scent bottle, includes a plug and a plunger. The plug has a bottom portion and a rib on the bottom portion with an edge. The plunger includes a body, a base wider than the body, and a shoulder connecting the base to the body. The plunger is adapted to mate with an opening in the neck of the bottle and is also adapted to be rigidly connected to the plug bottom. The plunger is made of a material different from that of the plug bottom. The base of the plunger is adapted to cooperate with the rib of the plug so as to rigidly connect the plunger to the plug. This is accomplished by applying heat to the rib and then folding the edge of the rib back against the shoulder so that this folded edge acts as an abutment for firmly holding the plunger in the plug. The rib may be composed of a thermo-meltable material.
