摘要:
Aspects of the present invention are directed to a tapered plug. The plug has a bottom base having a geometrical shape. In some embodiments the base has a well-defined geometrical shape, such as a circle, an ellipse, a triangle, a square, a rectangle, a rhombus, and the like. In other embodiments, the shape of the base is not a regular, well-defined shape. In some embodiments, the plug comes to a point at the top, with a shape analogous to a cone, while in other embodiments, the top of the plug is flat. In some embodiments, the plug has a smooth or nearly smooth surface, made of an easily compressible or semi-compressible material. It is for use in stopping or slowing the flow of a fluid or gas or other flowable material through an opening that the plug is inserted into.
