Pressure-actuated bubble blowing toy

Claim 1

A bubble-blowing toy comprising a hollow compressible container having a top open end defined by a neck anD a closed bottom end, said container being adapted to hold a supply of bubble-forming liquid, an insert mounted within the interior of said container and comprising a well member mounted within said neck, the upper portion of said well member tightly fitting said neck and forming an effective liquid seal therewith, a cylinder depending from the bottom wall of said well, said cylinder being substantially sealed by a piston slidably mounted therein for movement between a lowered, inoperative position and a raised, operative position, said cylinder having a top open end communicating with said well and a bottom open end communicating with the interior of said container, a liquid inlet tube in said well offset from said cylinder, a pipe secured at one end to said tube and depending therefrom, the bottom end of said pipe being located adjacent the closed bottom end of said container, said pipe and tube forming a passage between said bottom end of said container and said well, whereby when said container is supplied with liquid covering the bottom end of said pipe, and is compressed, air pressure within said container raises said piston to its operative position and forces bubble-forming liquid upwardly through said pipe and tube to the interior of said well to provide a supply of bubble-forming liquid in said well at the level of the top of said tube, and a film-supporting ring mounted at the top of said piston and projecting longitudinally thereabove,said ring being located within said well and being submerged in the supply of bubble-forming liquid in said well in the lowered, inoperative position of said piston, said ring being positioned above the top edge of said well and of said container neck in the raised, operative position of said piston.
