The latter returns to the solution bygravity when the air input is discontinued. The above device must be carefully hand held when in use to avoid spillage of the solution from the open receptacle.
SUMMARY OF THE INVENTION The animated bubble forming device of this invention is mounted on a cap which is worn on the head and is provided with a flexible hose reaching to the mouth and having a mouthpiece so that bubbles may be formed by blowing into the mouthpiece while the hands are'free. As in the above mentioned prior art device, a pair of telescoping tubular members are provided, one of which may be integrally formed with and extends from the bottom of the receptacle and being open at both ends. Air blown into the lower end will raise the other tubular member which is provided with a cover. The other tubular member carries the film forming device which moves into and out of the film forming solution. Another distinguishing feature over the prior art is that the solution container or receptacle is of truncated conical shape with the end of smaller diameter forming the base The container is provided with a cover having an opening spaced from the rim thereof and of a size and shape to just allow passage of the film forming member, which together with the shape of the container minimizes spillage of the solution. Further, the telescoping members are provided with longitudinal spacing means between them to maintain them in concentric relation with a minimum of frictional surface contact. The upper end of the movable tubular member is provided with'a freely rotatable propeller which is rotated by air passing through small openings in the cover of the tubular member when air is blown into the flexible conduit. The above and other improvements over the prior art will be pointed out in detail with specific reference to the drawings.
OBJECTS OF THE INVENTION It is therefore an object of the invention to provide an animated bubble forming toy which can be carried on the head.
It 'is another object of the invention to provide the above toy with a container for the bubble forming solution which is not easily spillable.
alt is a further object of the invention to provide the above toy with movable telescoping tubular members which are maintained concentric and have a minimum of surface contact to avoid sticking.
It is still a further object of the invention to provide a more animated toy by the addition of a freely movable blade or propeller which is rotated by air blown into the same inlet as used for forming the bubble.

DESCRIPTION OF THE INVENTION With particular attention to the drawing, a base 1 for the bubble forming device is in the form of a hat which may be fastened to a childs head by means of a chin strap 2. The hat may be of any preferred material including a rigid plastic. Attached to the hat is the receptacle or container 4 for the bubble forming solution. As shown, the container is of frusto-conical shape with the smaller diameter end forming the base of the container. Rising centrally upward from the base 5 of the container and formed integral therewith, are a pair of spaced outer and inner concentric tubular members 6 I and 8. The larger diameter end of the container is provided with a top wall 10 extending between rim of the container and the outer wall of the outer tubular member 6. The top wall may of course, be formed integrally with the container and member 6. The latter terminates at orjust above the top wall 10 of the liquid resevoir 4, while the fixed tubular member 8 extends further upwardly and is provided with an opening 13 through its peripheral wall.
In telescoping relation with the tubular members 6 and 8 and extending between them with a sliding fit, is a movable intermediate cylinder or tubular member 12 provided with a cover 14 which may be of any shape, preferrably domed to have the appearance of a cap and provided with a projecting piece 14 simulating the visor. The intermediate tubular member is provided with a key 17 slidable in a longitudinally extending keyway 18 in the inner tubular member 8. The keyway terminates intermediate the ends of member 8 to prevent the member 12 from escaping when forced upwardly, as later explained. The outer wall of the inner tubular member is is provided with longitudinally extending, circumferentially spaced ribs bearing against the inner wall of the movable member 12. It was found that splash from bursting bubbles could wet the surfaces between the tubular members 6 and 12 and the resulting viscous drag, between them would be so great that the movable tubular member 12 would stick in its upper position and not slide down to its lower position. The
ribs serve to maintain the concentricity of the cylindrical or tubular members with a minimum of surface contact between them to minimize viscous resistance.
Obviously, the ribs may be formed on the movable member instead. In the same way, ribs may be provided between the inner and outer walls of fixed tubular member 6 and movable tubular member 12 respectively, if so desired.
Fixed to the outer wall of the movable member 12, centrally of and below the visor 16, is the film forming device 20 similar to that disclosed in the aforementioned patent. The device is of flat material having an attaching portion 22 which is fixed to the outer wall of member 12 and a dipring portion 24 offset by an amount equal to the thickness of member 6 and extending parallel to the outer wall. The dip-ring is provided with a bubble forming opening 26 centrally below the visor. The device 20 is curved to conform to the curvature of the tubular member 6 which it overlies when in lowered position. The top wall of the container, is provided with a slot 28 through which the offset filmforming device 24 can move into or out of the container. The slot 28 is spaced radially inward of the outer periphery of the container and close to the tubular member 6 so that spillage of the contents will not take place even when tipped as much as 45 degrees in any direction, as shown in FIG. 6. The peripheral wall of the movable tubular member 12 is provided with an opening 30 therethrough which is in alinement with opening 26 in the film-forming device 20, the axes of openings 13, 26 and 30 being in a common vertical plane. The bottom wall 5 of the container has an inlet opening 32 registering with the outlet of a rigid conduit 34, to the inlet of which a flexible conduit 36 is attached. The flexible conduit is of a length to reach the mouth of the wearer of the bubble making toy and may be provided with a mouthpiece, if so desired. The domed cap 14 is provided centrally thereof with an elongated bearing 38 extending inwardly from the outer periphery of the cap. A propeller blade 40 is fixed on a shaft 42 wich is journaled in the bearing 38 for free rotation therein, the shaft extending through the bearing at its inner end and being retained therein by any desired manner such as by a washer 44 clamped on the inner end of the shaft. The domed cap is provided with one or more openings 44 through its upper wall to form a passageway for a stream of air from within the dome to impinge upon the blade to cause rotation thereof.
Air exiting from the opening 44 may also be utilized to create whistles, sirens or other sounds, as is known in the art. As can be seen from the drawing, the film forming member may be shaped to have face-like features and the dip-ring 24 may have the appearance of a mouth.
By blowing air into the flexible conduit, the pressure created within the tubular member 12 will force it upwardly, raising the dip-ring out of the bubble forming solution with a film of such solution adhering thereto. When the tubular member 12 is raised to such a height that the key 17 is at the upper end of slot 18, openings 26 and 30 in the dip-ring and movable member 12 respectively, are in alinement with opening 13 in fixed member 8, the air passes through such openings to direct air from within against bubble forming opening 26. The openings 44 in the cap 14 are of such small size that the slow leakage of air therethrough does not prevent the lifting of the movable member 12 and forming and ejecting of the bubbles from opening 26. When the air pressure is lowered or discontinued, the movable tubular member will descend to lower the film forming member into the solution.
The toy thus described is attractive, is animated and performs the function of blowing bubbles while leaving the hands free for other activities and is practically spillproof, permitting the wearer to move about in unrestricted fashion. The receptacle 14 may be formed integral with the cap 1 or secured directly thereto making provision for accommodating the conduit 34. The receptacle may also be formed with or have a clamp attached thereto for mounting on the handle bars of a bicycle, or to a rod or wand for holding it in the hand.
Having thus described the preferred form of the invention with the particularity required by the statutes, it should be understood that obvious changes by those skilled in the art may be made without departing from the spirit and scope of this invention.
