Today in 1932, US Patent 1863081 A was issued, an invention of Earl S. Bellows, assigned to the Huntington Rubber Mills, for his “Bottle Cap.” There’s no Abstract, although in the description it includes this summary:

My invention relates to closures for glass bottles designed to contain effervescent fluid .producing a pressure in the container; and it is also useful for inert fluids or for use 5 in bottling processes resultant in a partial vacuum in the top of the bottle after the contents have been placed therein.

The particular feature of my new bottle cap is its capability of being re-used many times and the provision made for removing it without the use of tools or implements which will tend to destroy it.
