PERETTI TOY BUBBLE BLOWING CAP 2 Sheets-Sheet 2 Filed NOV. 10, 1955 INVENTOR. LEO ARD GPeRa-rn Wo 9m ATTOQNEYS United States Patent TOY BUBBLE BLOWING CAP Leonard G. Peretti, Chicago, Ill. Application November 10, 1953, Serial No. 391,331 3 Claims. (Cl. 46-7) This invention relates to toys, and more particularly to a cap adapted to be secured on the neck of a vessel containing bubble forming liquid and provided with means for forming bubbles responsive to oscillation of the vessel.

A main object of the invention is to provide a novel and improved bubble forming device which is simple in construction, which is easy to operate, and which is arranged to provide a large number of bubbles in response to very simple movements thereof, such as can be readily performed by a very small child.

A further object of the invention is to provide an improved bubble forming cap adapted to be secured on the neck of a bottle or other vessel containing bubbleforming liquid, such as soapy water or the like, the cap being very inexpensive to manufacture, being durable in construction, and operating automatically to produce large quantities of bubbles as the vessel is waved or oscillated back and forth, the bubbles being produced without waste or spillage of the bubble-forming liquid, whereby an enormous quantity of bubbles may be produced from a relatively small quantity of bubble-forming liquid.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure l is a perspective view of a bubble-forming cap, constructed in accordance with the present invention, shown mounted on the neck of a vessel.

Figure 2 is an enlarged cross sectional view taken on the line 2-2 of Figure 1.

Figure 3 is an enlarged cross sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 2 and showing the bubble-forming device in a downwardly inclined position wherein the loop element thereof receives a film of bubble-forming liquid and a flexible valve member forms the bubble-forming film.

Figure 5 is a cross sectional view similar to Figure 4 but showing the device in an upwardly inclined position wherein air is drawn through the loop element and into the film to form bubbles, as the device is rotated upwardly from the position of Figure 4.

Figure 6 is a perspective view of a modified form of bubble-forming cap in accordance with the present invention.

Figure 7 is an enlarged vertical cross sectional view taken on the line 7-7 of Figure 6.

Referring to the drawings, and more particularly to Figures 1 to 5, 11 designates a bottle adapted to contain bubble-forming liquid, such as soapy water or the like. Designated generally at 12 is an improved bubbleforming cap according to the present invention, said cap comprising the main cap element 13 which is provided with the threads 14 adapted to be threadedly engaged with external threads on the neck 15 of the bottle 11. Centrally secured in the cap element 13 is a rigid tube 16, said tube being provided with the flattened, expanded outer end portion 17. Designated at 18 is a loop member formed of a length of wire material bent to define an enlarged main loop portion and a pair of ends 19, 19. The ends 19., 19 are received in and secured in the widened end portion 17 of tube 16 in the manner shown in Figure 2, the ends 19, 19 being spaced from each other to define a passage through which bubble-forming liquid may flow from the tube 16 into the loop 18.

Rigidly secured to the tube 16 adjacent the cap element 13 is the transversely extending metal band 20 in which is secured the reduced end portion 21 of a flap member 22, said reduced end portion 21 being clampingly secured on the band 20 by the clamping end flange elements 23 which are engaged over the opposite mar ginal portions of reduced section 21 of flap 22 and thereby frictionally secure the reduced portion 21 substantially against the tube 16 in a position parallel to and normally closely adjacent to the loop member 18.

The flap member 22 may be formed of any suitable flexible sheet material, such as sheet plastic material or the like. As shown, the main body portion of the flap member is generally circular in shape and is substantially larger in diameter than the main body of the ,loop 18, said flap member being arranged to abut the main portion of the loop in the manner shown in Figure 2 and to be flexed away from the loop in response to air pressure when the device is waved upwardly from the position of Figure 4 to the position of Figure 5.

In operation, when the device is in the position of Figure 4, bubble-forming liquid is allowed to flow downwardly and outwardly through the tube 16 and into the main portion of the loop 18. When the device is oscillated or waved upwardly from the position of Figure 4,

to the position of Figure 5, the flap 2 2 flexes away from the loop and leavesa film therein, air passes through the loop 18 and into the film, forcing the film downwardly and outwardly of the loop, causing the air to form bubbles which escape from the device between the loop and the downwardly flexed flap member 22 in the manner shown in Figure 5. Thereafter, the device is oscillated downwardly toward the position of Figure 4, wherein the flap member 22 engages the loop 18 to form another film therein and bubble-forming liquid again enters the loop, allowing the above described procedure to be repeated.

Referring now to Figures 6 and 7, 13' designates a cap element adapted to be threadedly engaged on the neck of a vessel containing bubble-forming liquid. Secured in and extending through the cap 13' are a pair of rigid tubes 31, 31, said tubes being provided with the upwardly and outwardly inclined, flattened, flared end portions 32, 32, clearly shown in Figures 6 and 7. Secured in each flared portion 32 is a loop 33 of wire material, the end portions of the loop 33 being shown at 34 and being secured in the flared portion 32 in spaced relation to define passages therebetween through which bubbleforrrn'ng liquid may flow from the tubes 31 into the loops 33. Rigidly secured to one of the tubes 31 is a transversely extending clamping band 35 in which the reduced portion 36 of a flap member 37 is secured, said flap member being thus secured between the respective upwardly and outwardly inclined loops 33. As shown in Figure 7, the flap member 37 normally assumes a vertical position, the upwardly and outwardly inclined loops 33 being located symmetrically on opposite sides of the plane of the flap member 37. The main body portion of the flap member 37 is substantially circular and is substantially larger in diameter than the diameters of the respective main portions of loops 33, 33, whereby the flap member 37 may be alternately disposed against tween the said first loop and the flap member 37 as said flap' member flexes into engagement with the other loop to form a film therein. At the same time bubble-forming liquid forms a film in the other loop, andwhen the device is waved in the opposite direction, bubbles are formed by the movement of air through the second loop and into the film therein, the bubbles emerging from the space between the flap member and the second loop,

, p, substantially in the same manner as previously described.

Therefore, as the device is waved backtand forth, bubbles are formed with each movement of the device, producing twice the number of bubbles formed by the device illustrated in Figures 1 to 5.

While certain specific embodiments of a bubble-forming toy devices have been disclosed in the foregoing description, it will be understood that various modifications withinthe spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limi tations be placed on the invention except as defined by thelscope of the appended claims.
