Abstract:
A container for use with a gravity feed liquid spraying device having a liquid inlet port, said container comprising:an elongate body portion formed of thin flexible polymeric material, said body portion having a central axis, and having axially spaced first and second ends; means for closing the second end of said body portion; a first adapter attached to said first end of said body portion, said body portion, means for closing, and first adapter having inner surfaces defining a cavity in said container, said first adapter comprising a engagement portion having a through opening communicating with the cavity in said container and being adapted for liquid and air tight engagement with the inlet port of the liquid spraying device; and a plurality of stiff rings fixed to and spaced axially along said body portion; the container being capable of being filled with liquid by manually collapsing the body portion of the container between the rings, engaging one end portion of a transfer pipette with an inner surface of the engagement portion and immersing an opposite end portion of the transfer pipette in the liquid, and pulling the second end of the body portion away from the first end of the body portion to cause the cavity to expand in volume so that atmospheric pressure pushes liquid into the cavity in the container through the transfer pipette, and said body portion being collapsible between said rings to afford movement of said rings to positions closely adjacent each other to decrease the volume of said cavity in the container as liquid in the container moves through the opening in said first adapter with said second end of said container uppermost, thereby restricting formation of a vacuum in the cavity.
