7 Claims, 6 Drawing Figures BUBBLE BLOWING DEVICE BACKGROUND OF THE INVENTION The present invention relates generally to the field of More recently, special wands have been developed which comprise a stem affixed to an'annular member of suitable size for dipping into a container of soap solution. After applying the soap solution to the wand by dipping and then rapidly fanning the wand through the air in a direction normal to a plane drawn through the annular section, bubbles could accordingly be produced by the air pressure thus developed. These prior art types of devices have provided many hours of enjoyment for children, but such devices are now becoming passe and stereotyped. Accordingly, the conventional types of bubble blowing pipes and wands are losing favor because they are not stimulating enough to excide the more sophisticated tastes of today's children.

SUMMARY OF THE INVENTION The present invention relates generally to bubble blowing devices, and more particularly, is directed to a novel combination bubble solution container and bubble blowing apparatus.

The apparatus of the present invention comprises a decorative holder which, in the present embodiment, may be conveniently molded in the form of the configuration of a monkeys head or other configuration in accordance with well established principles. The decorative holder is generally hollow in form in accordance with conventional injection or blow molding techniques and terminates upwardly in an opening of size to receive a soap container therein. Peripherally outwardly from the opening are integrally molded a pair of opposed hinge members which are vertically elongated to pivotally and adjustably receive the combination closure and bubble producing cap. The closure and bubble producing cap is equipped with integral molded pins which pivot about the hinge members from an open position wherein the closure seals the bubble solution within the soap container.

The bubble producing cap includes a concentric opening provided with an exteriorally extending boss for connection of a blowing rod or stem. Interiorly, the opening is equipped with a boss extension to which an inwardly extending ring which is suitable to dip into the soap solution and to retain a portion thereof for bubble blowing purposes is suitably suspended. The pivotal connection between the cap and the decorative holder is arranged for both pivoting the cap relative to the holder and also to permit limited vertical adjustment of the cap during the opening and closing procedure. The vertical adjustment of the hinge members permits the integral molded plastic hinge pin of the cap to be pivot- 2 ally affixed by an angular movement to thereby eliminate the need for metallic pins, springs and the like.

It is, therefore, an object of the present invention to provide an improved bubble blowing device of the type set forth.

It is another object of the present invention to provide a novel bubble blowing device incorporating a decorative holder having a soap container therein and a combination closure and bubble producing cap hingedly connected to the decorative holder.

It is another object of the present invention to provide a novel bubble blowing device incorporating a decorative holder and soap container arranged therein, the said decorative holder being equipped with a pair of vertically elongated hinge members which pivotally and vertically adjustably receive the integral hinge pin of a closure and bubble producing cap.

It is another object of the present invention to provide a novel bubble blowing device having a decorative holder and soap container therein and a combination closure and bubble blowing cap hingedly connected to the decorative holder, the cap having integral opposed pins molded in the cap which cooperate with integral elongated hinge members which are integrally molded with the decorative holder.

It is another object of the present invention to provide a novel bubble blowing device which includes a decorative holder and a soap solution container arranged therein, vertically elongated hinge members molded with the decorativeholder adjacent the soap container and a combination closure and bubble blowing cap hingedly connected to the hinge members, said cap including a concentric opening for producing bubbles and an interior molded bubble ring which dips into the soap container when in the closed position and retains a portion of the soap solutionwhen pivoted to the open position for bubble blowing purposes.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION Although specific terms are used in the following description for the sake of clarity, these terms are intended to refer only to the particular structure of my invention selected for illustration in the drawings, and are not intended to define or limit the scope of the invention.

Referring now to the drawings. I show in FIG. I a bubble blowing device which includes a decorative holder 12 which is fabricated of plastic material such as styrene which is suitable for molding to a hollow configuration in accordance with well known injection or blow molding techniques. In the illustration shown, the decorative holder has been molded to the form of a stylized monkeys head as illustrative of the type decorative device which may be employed in conjunction with the present invention. It is the purpose of the decorative configuration to impart an attractive appearance to the device to be most attractive to children. A combination closure and bubble producing cap 14 hingedly connects to the decorative holder 12 for both closure purposes and for bubble producing purposes as hereinafter more fully set forth.

As best seen in FIGS. 2, 3, and 4, the decorative holder 12 is formed by molding or otherwise to a hollow interior configuration l6 and terminates upwardly in a circular opening 18 through which the interior I6 is readily accessible. Integrally molded with the holder 12 are a pair of spaced, vertically

elongated hinge members

20, 22 which are positioned peripherally outwardly from the top circular opening 18. The

hinge members

20, 22 project vertically upwardly from the top 24 of the holder 12. As best seen in FIGS. 3 and 4, an inwardly extending boss 52, which may be integral, inward extension of the boss 38, inwardly surrounds the concentric opening 36. The attaching rings 48 may be cemented or otherwise affixed to the inwardly extending boss 52 to thereby provide a sturdy, concentric base to carry the bubble blowing ring 44. The closure and bubble producing cap 14 includes a peripheral, depending sidewall 54 which terminates downwardly in a peripheral tongue 56 for cup closure purposes.

Referring still to FIGS. 3 and 4, I show a molded, plastic cup 58 of generally cylindrical construction of size to fit within the top opening 18 and having cylindrical sidewall 60 and an integral bottom closure 62. The sidewall 60 terminates upwardly in an annular flange 64 which seats upon the top surface of the decorative holder 12. The sidewall 60 should be fabricated to a diameter slightly less than the diameter of the circular opening 18 to thereby permit easy assembly. The peripheral tongue 56 of the cap sidewall 54 is fabricated to be a press fit within the cup 58 to thereby seal the liquid soap solution (not shown) within the cup 58 when the cap 14 is in the closed position as illustrated in FIG. 3. When the cap 14 is pivoted about the

hinge members

20, 22 to the open position as illustrated in FIG. 4, the cup 58 is thus exposed for either adding or removing additional soap bubble solutions (not shown).

The

hinge members

20, 22 project upwardly from the top surface 24 of the decorative holder 12 and are molded to provide a pair of facing, vertically

oriented recesses

26, 28 for hinge operational purposes as hereinafter more fully set forth. The

vertical recesses

26, 28

are bottomly closed by the top surface 24 of the decorative holder 12. The

recesses

26, 28 are upwardly closed by integral, molded

end closures

30, 32 to receive and retain the transverse, molded hinge pin 34 of the cap 14 in the manner hereinafter more fully set forth.

As seen in FIGS. 3 and 4, the combination closure and bubble producing cap 14 is provided with a concentric center opening 36 of size to permit sufficient air for bubble blowing purposes to pass therethrough. An exterior boss 38 is provided in conjunction with the cap 14 and may be integrally molded therewith. The boss 38 extends upwardly a sufficient distance to provide a suitable seat for receipt of the bubble blowing rod or stem 40. The stem 40 may be conventionally molded or extruded of flexible plastic material such as styrene or polyethylene plastic and is provided with a longitudinally extending central bore 42 of size to closely overfit and frictionally engage the boss 38. Thus, by affixing one end of the stem 40 onto the boss 38, an extending rod can be provided to permit convenient operation to blow air through the concentric opening 36.

Interiorly of the cap 14 is provided a bubble blowing ring 44 which is interiorly carried in spaced relationship from the cap 14 by a plurality of peripherally spaced struts 46. The struts 46 terminate upwardly in an attaching ring 48 which may be cemented. The struts 46 should be fabricated just long enough to permit the bubble blowing ring 44 to clear the sidewall of the cup 58 when the cap 14 is pivoted between the open and closed positions.

As best seen in FIG. 1, the combined closure and bubble producing cap 14 is provided near the bottom edge of the sidewall 54 with an integrally molded, radially outwardly extending strap 66 which terminates outwardly in an integral, transverse hinge pin 34. The hinge pin 34 includes the outwardly projecting

opposed pin members

68, 70. The distance between the ends of the

pin members

68, 70 is constructed greater than the distance between the

hinge members

20, 22 as measured horizontally across the top surface 24 and is substantially equal to the horizontal distance measured between the

respective bottoms

27, 29 of the

recesses

26, 28. See FIG. 6. Further, the geometry of the system is such that the distance between the ends of the

pin members

68, 70 is just slightly greater than the diagonal distance between the bottom of one vertical recess 26 and the top of the other vertical recess 28 of the

hinge members

20, 22 respectively. By utilizing this construction, and by angularly positioning the hinge pin 34 relative to the

hinge members

20, 22, the

opposed pin members

68, 70 can be associated with the respective right and left

vertical recesses

26, 28 by slightly flexing one of the pin members 70 sufficiently to allow it to pass the top closure 32 and to enter into the vertical recess 28. See FIG. 5. Then, by horizontally aligning the hinge pin 34 between the

hinge members

20, 22, as in FIG. 6, the hinge pin is free to vertically rise or fall within the vertival recesses 26, 28 and to pivot thereabout. The hinge member construction about the

vertical recesses

26, 28 retains the hinge pin 34 in association with the

hinge members

20, 22. In this manner, the need for separate, metallic hinge pins, spring activated hinge pins or other more costly and complicated hinge devices can be completely eliminated.

Although I have described the present invention with reference to the particular embodiments therein set forth, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction may be resorted to without departing from the spirit and scope of the invention.
