The drawing shows a bottle 1, which may contain liquid, having an internal rubber stopper 3 secured by the bottle itself. Molded rubber stopper 3 is pressed into bottle 1 approximately 0.12 inch Å 0.02 inch below the highest surface of bottle 1. The area above stopper 3 is then heated by convection or conduction until the material of bottle 1 is pliable, typically 12 seconds. A disk or plate (not shown) is then pressed down to roll the top 5 of bottle 1 over stopper 3. Cap 7 is then threaded onto bottle 1 conventionally. In this manner, the existing material of bottle 1 is used to secure the rubber seal 3.
