Claims9
A syringe comprising:
- a plunger,
- a substantially rigid cylindrical body, said body having an axis, an outer surface and an inner surface, a nozzle end, and a plunger end, the plunger end having an outwardly flared flange, the flange having a radial leading surface, and a lip, the leading surface of the flange blending the outer surface of the syringe body with said flange lip, the plunger end the syringe body having disposed thereabout,
- a flexible, conformable finger grip collar, said collar having inner and outer surfaces and being substantially radially symmetric with respect to said axis, said inner surface being concave and being adapted to cooperate with the leading surface of said flange to prevent said body from passing through said collar, the outer surface of said collar defining a continuous multiplicity of radially disposed facets and a finger contacting surface, said facets being substantially flat whereby the facets prevent the syringe from rolling when the syringe is placed upon a horizontal surface and the collar disposes the axis of the syringe at an angle with respect to a horizontal surface upon which the syringe may be placed.
