ABSTRACT:
A non-stick stopper with easy removal structure includes a device having an integral body with an upper portion for use in removing the stopper and a lower portion of special configuration for relatively non-compressive sealing with a tapered neck of a glass container. In one embodiment of the invention, an elongated pin handle is inserted through a traversely extending aperture in the body upper portion for use of a tool and/or a user's hand for ease in removing the stopper from the container. The tool is specially configured with a U-shaped recess bottle engaging portion at one end of an elongated handle. The U-shaped stopper engaging portion has double recesses from either side thereof so that the tool can be used with both the first embodiment and the second embodiment of the invention.
The second embodiment involves an inverted cone-shaped stopper having a radially extending stopper removing flange at one end thereof and a further conical closure structure at the other end thereof. The same tool as used for easy removal in the first embodiment can be used with this embodiment merely by reversing same 180.degree. from its original position.
