ABSTRACT:
An improved pressure-actuated bubble blowing toy comprising a container and an insert therein, in which the insert is composed of an cylinder, a piston, and a film forming ring connected to the upper end of the piston, and characterized by the design of the piston with a base plate having a cut portion and a plurality of raised portions on its upper surface, and the cylinder have a rail on the inner wall of its lower portion so that by aligning the cut portion of the piston with the rail, the rising and lowering of the piston can be maintained in a fixed direction without unwanted rotation, and the raised portions provide passages for liquid to enter the upper portion of the cylinder to form film on the film forming ring where the base plate is contacted with the a stop ring between the upper and lower cylinder portions of the cylinder. The film forming ring is an elastic diamond body with contractible width while its length can be extended correspondingly so that it can be contracted for inserting into the upper cylinder portion and its width can be expanded while it is extended out of the cylinder for forming of larger bubbles.
