Method of making bubbles and toys to carry out the procedure,

The invention relates to a method for producing bubbles and a bubble-generating device, in particular a toy, that can create bubbles when swirling around in the air.

A long-time favorite pastime and constant source of entertainment and excitement for children is creation of bubbles from soapy solutions. Numerous devices have been used and proposed for this purpose over time. They are partly simple and partly more complex. Perhaps the most common bubble generating devices include Rings or dip sticks that are dipped in a solution. The resulting soap films then become bubbles as a result converted by either blowing against the films or moving them through the air.

Designs of such devices are disclosed in U.S. Patents 3,295,248 and 2,858,639. Although these devices are easy to use, they are accompanied by dripping,

Propeller, whose film-forming rings are limited and sprinkled with a Drifting source of bubble-generating fluid. The object of the invention is simple, cheap and particularly amusing To create toys for the simultaneous production of many bubbles that are actually indestructible under normal working conditions and has either very few or no moving parts.

The object of the invention is also to propose a method which allows the use of such a toy.

An inventive method for producing bubbles provides that a device with a bubble generating A container containing liquid and a hollow handle with lateral perforations is swung through the air, Bubble-generating liquid due to the constant centrifugal force occurring on the device from the container to the inner circumference of the hollow shaft is driven and distributed over areas of the inner circumference of the hollow shaft, and at least one of the Breakthroughs are covered with a thin film of the bubble-generating liquid, and the thin film is blown up by the flow of air turning the film into a bubble.

An inventive bubble-generating toy is designed so that at least one on the bottom part of a container Outlet opening is provided and a hollow stem is attached which surrounds the outlet opening and several on its side wall Has breakthroughs. When the toy is grasped and moved, the centrifugal force and / or gravity allows it to create bubbles Liquid flow through the outlet opening to the inner circumference of the hollow stem. This will at least some of the Openings covered with a PiIm of the soapy liquid. When the films are exposed to a stream of air, they transform into bubbles. Some of these bubbles will stick together and form clusters or clusters of bubbles.

In a preferred embodiment is on the bottom part of the container opposite A line is attached to the area of the container. This makes it possible for the user to use the toy on one Swing around a circular path. The resulting centrifugal force drives bubble-generating liquid outward into the hollow stem. On the other hand, the user can simply take hold of the toy and wag or swing back and forth on a narrow path. In doing so, gravity eventually becomes part of it cause bubble-generating liquid to flow to the perforations.

Preferably there are several outlet openings on the bottom part of the Container provided and at least some of them are provided in the region of the inner edge of the open end of the hollow stem. This will increase the distribution of bubble-generating liquid

the inside of the hollow handle facilitated.

In preferred embodiments of the invention, the container either spherical or cylindrical and has one or more air inlet openings, so that the gradual If the liquid that creates bubbles flows out, no vacuum is created in the container. To facilitate the filling of the bubble generating Liquid, a removable cap is provided which covers a refill opening provided on the container. Here is the leash is attached to the removable cap.

In a preferred embodiment, the hollow handle is tubular formed with an open end facing away from the container. The open end allows air to enter the hollow stem through the numerous breakthroughs has flown in, flow out to a To achieve intensification of blistering. The hollow stem preferably has a plurality of perforations in the longitudinal direction, the Progress towards the end of the hollow handle facing away from the container.

In another embodiment of a toy according to the invention, closure means are provided for the outlet opening of the container intended. This makes it possible to selectively open and close the outlet opening on the bottom part of the container, so that the flow of bubble-generating liquid can be released or interrupted. Preferably the locking means are a slide valve which is formed by a wall area of the hollow stem. In particular, there is the bottom part of the container from a sleeve, the from a shell with several spaced outlet openings and a collar part with a radial Slit is formed. The hollow handle has several spaced notches which are assigned to the outlet openings. A The plug extends through the radial slot to hold the container and the hollow stem together and is with the hollow stem tied together. The stopper limits the amount of space between the container and the hollow stem when the closure means are opened and closed possible rotation.

Further advantages and embodiments of the invention emerge from the following description of the drawings. Show it: Figure 1 is a perspective view of the user of a toy according to the invention,

In'Figur 1 a user is shown, the bubble generating The toy (10) oscillates through the air in a substantially circular path to create bubbles (B). The toy (10) has a container (11) which forms a reservoir for bubble-generating liquid. Next, the toy (10) a hollow stem (12) attached to the container (11) and extending outwardly therefrom. The hollow handle (12) is provided with a plurality of perforations (13) between its ends. At one end of the container (11) is a line (14) attached, which expires in a handle (15). A user can take this handle with one hand (16) to play the game, tool (10) to whiz through the air.

In Figure 2, the container (11) is with a spherical reservoir a bottom part (20) is formed. The bottom part (20) has a A plurality of outlet openings (21). Bubble-generating liquid enters or drips under the action of centrifugal force

4098 15/0251

_ ₇ _ 231B497

and / or gravity through the outlet openings (21) in the adjacent hollow stem (12). The hollow handle (12) has an inner end (23) which faces the container (11) and which is open and is attached to the bottom part (20) of the container in such a way that it encloses the outlet openings (21) and delimits them together. The hollow handle (12) is round in cross section and has a side wall (24) with an inner circumference (25) and an outer circumference (26). The numerous openings (13) extend completely through the side wall (24) from the inner circumference (25) to the outer circumference (26).

While the toy is in use, proportions of the bubble will be generated Liquid (22) constantly driven through the outlet openings (21), as indicated by the directional arrows (27) is. The resulting droplets (28) or similar liquid particles hit the inner circumference (25) and distribute them yourself there. They dissolve and stretch over the openings (13) · As a result, thin films (F) are the bubble-generating Liquid formed. The breakthroughs (13) are repeated with a thin film (F) of the bubble-generating liquid provided as long as the external force, i.e. the centrifugal force and / or the force of gravity, acts on the liquid.

The bottom part (20) of the container and the end (23) of the hollow handle (12) facing the container are in the exemplary embodiment formed in one piece according to FIG. Optionally, the hollow handle (12) can be movably attached to the base part (20), as shown on Hand of Figures 6 and 7 is described. The container (11) and the hollow stem (12) can be made of cast part-sections

4 09815/0251

be composed.

If necessary, a removable drop collecting cap can be used (36) attached to the outer end of the hollow stem (12), which is not shown in FIG. 2, or the end facing away from the container be. The closure (36) can by a force-fit Connection, a screw connection, by snap elements or the like. Be fixed. A job of the lock (36) is to avoid the leakage and splashing out of excess bubble-generating liquid (22) throughout the whole Has passed through the length of the hollow stem (12). Another job of the closure (36) is to generate excess bubbles Collect and store liquid (22) for possible reuse or disposal. With regard to on this a plastic or rubber sponge (37) is arranged inside the closure (36), which absorbs the liquid (22) and their manageability is improved. For decoration or entertainment, an impeller ″ or propeller is attached to the closure (36) (38) attached. For example, when the sponge (37) is saturated, the closure (36) can be removed from the hollow handle (12) so that the liquid held in the sponge (37) can be squeezed out and poured into the container (11).

In figure. 3 is the bubble-generating toy (10) swung in the direction of arrow (D), so that the ambient air on the Hollow shaft hits and air currents (A) arise that hit the openings (.13) and consequently through the openings (13) stream. The interaction between the air currents (A) and the thin films (F) results in many

4098 15/0251

Bubbles are generated at the same time. YoIl molded and detached Bubbles are labeled (B). Bubbles that are only partially formed are labeled (B1). Some bubbles are shown sticking together in groups or clusters of different sizes. The centrifugal force (Cf) acting on the container the bubble-generating liquid acts, constantly drives further drops to the inner circumference (25) of the hollow stem (12), so that the bubbles are continuously generated until the bubble generating liquid is consumed. The area or the The end of the container (11) opposite the base part (20) is provided with a threaded neck (30) which forms a filling opening, which is closed with a removable cap (31). In the middle part of the removable cap (31) is a tether or a line (14) attached. At the neck (30) one or more air inlet openings (32) are provided, which the formation a vacuum in the container (11), when the bubble-generating liquid is constantly expelled and emptied, prevents. When the bubble-generating liquid is largely used up, the cap (31) can be removed, and the container (11) can with bubble-generating liquid again be replenished.

The hollow handle (12) is essentially tubular with a circular shape Cross-section formed. Its end (33) facing away from the container is open so that parts of the air streams flow out can, whereby the bubble generation of the toy (10) increases. Usually the toy bubble generation (10) stronger when the closure (36) shown in Figure 2 is removed. Depending on the path on which the toy (10) moves

409815/0251

there may be some bubbles on the far end of the container (33) form and from the open applied by the container The opening formed at the end (33) escape.

In Figure 4 is an additional embodiment of an inventive Toys shown. In contrast to the previously described embodiment example, the container (11) consists of a cylindrical G-housing (35). With this design, the Bubble-generating liquid can be essentially entirely used up before the container needs to be refilled. Assuming that a spherical and a cylindrical container have the same volume, then the cylindrical one requires Refill containers less often.

The hollow handle (12) has a number extending in the longitudinal direction Rows of perforations which are essentially evenly spaced between the end (23) facing the container and the end (33) facing away from the container are formed. The openings in adjacent rows are staggered, see above that a mutual contact of the developing bubbles is largely avoided. The openings are preferred elongated or oval, with its major axis parallel to the longitudinal axis of the hollow stem. The breakthroughs (13 A) of the row lying in the middle are arranged in a staggered manner opposite the openings (13) of the adjacent rows.

It is not absolutely necessary to have a leash (14) on the container

(11) or to be attached to the removable cap (31), so far

it is not necessary to use the bubble-generating toy to swing around a closed circular path. The interaction of gravity and the movement of air through the openings can create bubbles. For example, a user can attach the toy to the cap (31) or to the cylindrical housing (35) and swing the toy back and forth like this on a relatively short trajectory like this indicated by the arrow (P). The force of gravity will cause liquid to constantly fill the openings (13 and 13A), while the impinging air creates bubbles from the films. the Bubbles generated in this way will be fewer in number than those produced when handling as shown in FIG. 3 has been described. However, bubbles can also be produced, albeit in fewer numbers, although the toy It is absolutely still as long as a wind breeze or a fan is pushing air through the openings (13 and 13A).

In Figure 5, the bubble generating toy (10) is in a hollow one Upright vessel (40) inserted and carried by this. The stand

(41) Vessel (40) has a level base and an upper end or a neck (42), the diameter of which is just slightly larger than the diameter of the hollow stem. The standing vessel can be put down of the toy (10) can be used when not in use. It allows excess fluid from the toy (10) to be diverted and stored, and serves as a compartment filling or auxiliary container. In particular, however, the jar can be used for Support for the initial formation of thin films (F) of the bubble-generating liquid may be needed. One way the creation to initiate these initially formed films

40981 5/0251

in that, gently shaking the toy (10) until it produces bubbles Liquid flows into the hollow stem (12). At this time the toy (10) can be alternately pushed back and forth while rotating in the container (40). The tight closure between the neck (42) and the hollow stem (1'2) promotes the spreading or distribution of the liquid through the openings (13) to form the films (F).

On the other hand, the hollow handle (12) can be directly in a supply of bubble-generating liquid. It is clear, however, that it is not necessary to have films on the perforations to form before the toy (10) is used. The main advantage when using the jar (40) in the manner described above, it is that the production of the films (F) faster goes on so that the bubbles can also be generated more quickly. Once the films (F) are formed in some way and the force of gravity and / or centrifugal force acts on the container liquid, some of the perforations are made steadily replenished, whereby the films (F) are maintained.

The total length (L2) of the hollow shaft (12) is preferably at least one and a half times as large as the length (L1) of the container (11).

Another embodiment of the toy is shown in FIG and FIG. 7. This is characterized by a storage container (50) which consists of a cylindrical housing (51) with a bottom part (52). The bottom part (52) is a

4 0 9 8 15/0251

Sleeve whose diameter is smaller than that of the housing (51). The bottom part (52) comprises a collar part (53) in which a slot (54) extending in the radial direction is provided. A hollow iä. (55) is movably coupled to the bottom part (52). The end (56) of the hollow stem (55) facing the container is inserted completely into the collar part (53). The hollow handle (55) has a plurality of rows of elongated openings (58) and several offset rows of elongated openings (59). The openings in adjacent rows are staggered against each other. A plug (60) extends all the way through the slot (54) and sits in the hollow stem (55). The plug (60) can optionally be moved by hand to any point between the ends of the slot (54). The storage container (50) and the hollow handle (55) can be rotated relative to one another on an arc which is the same as the arc delimited by the slot (54).

In Figure 7, the storage container (50) and the hollow handle (55) are rotatably coupled by locking means. The locking means serve to selectively interrupt or release the flow of bubble-generating liquid (70). The bottom part (52) has an inverted shell (63) which is arranged so that it extends partially into the interior of the cylindrical Housing (51) extends. The shell (63) is provided with a plurality of equally spaced through openings, such as the passage openings (64, 65 and 66) are provided. The shell (63) and the cylindrical housing (51) delimit a toroidal Channel (68), which partly serves as a trap for deposits (69), which are usually below the level of the perforations

409815/0251

(64, 65 and 66) fall so that they do not result in clumping or any other impairment of the free flow of the liquid (70) into the hollow stem (55); The direction of flow of the liquid is indicated by the arrows (71 '). The resulting drops (72) of the liquid (70) flowing on the inner periphery of the hollow stem (55) and consequently form in d ^r he described above, the films (F).

An upper wall area (75) of the hollow stem (55) forms a slide valve and its edge is at the same distance arranged notches (76, 77 and 78). In the position shown in the figure, the notches are aligned with the associated Passages (64, 65 and 66). Locking shoulders (80 and 81) are located between the notches Cover the passage openings and thereby interrupt the flow of liquid (7Q). When the slide valve is completely closed is, then the individual components assume the position as shown in FIG. When the slide valve is completely is open, then .the components assume the position shown in FIG. The sizes, shapes and number of openings the notches and the locking shoulders can be modified so that the flow rate is set within certain limits " can be. For example, the passage openings can be assigned to radial archers, which can be partially blocked, so that a predetermined flow rate can be set to produce a predetermined amount of bubbles. -

If you keep in mind the structure of the toy described above and how it works, you can see how the above-described disadvantages of known bubble generating toys are avoided or substantially "avoided" by the present invention are turned off.

The mode of operation of the toy (10) is described with reference to FIGS. 2, 3 and 5. Before trying to make bubbles, can the user preform thin films (F) at the openings (13) by inserting the hollow handle (12) into the empty container (40) begins. Bubble-generating liquid (22) flows through the passage openings under the action of gravity

(21) to the inner circumference and to the outside through some of the perforations (13). Due to the tight closure between the neck (42) and the hollow handle (12), a hand-held one promotes Reversing and rotating the hollow handle (12) spreading the liquid in general and stretching films over it the openings (13) in detail. This starting process creates the first or pre-formed films.

The hollow stem (12) is then used to receive and distribute the drops or fill quantities of the bubble-generating liquid

(22) prepared in uninterrupted sequence as long as the centrifugal force and / or gravity is exerted on the container liquid. The drops (28) that are evenly replenished are constantly spreading over the openings, filling them up and keeping the films (F) upright.

A09815 / 0251

When the air flows (A) through the film-coated Breakthroughs (13) flow, the films (P) form in Partial bubbles (B1) and finally into fully formed bubbles (B). When a fully formed bladder emerges from its eruption dissolves, either the film left behind creates another bubble or, if this film is completely broken, then a new film quickly forms due to the flowing drops of liquid. In any case, the opening is filled again with a film to form more bubbles. The cycle continues until either the container liquid is consumed or the user ends the force of gravity and / or centrifugal force exerted on the container liquid or the flow of the liquid is interrupted by external means.

The toy can be on a circular path in a horizontal plane, in a circular path with a vertical plane or in each Another curved path can be swung on which a centrifugal force and / or a gravity force on the bubble generating Liquid (22) is applied. Alternating smaller and larger bubbles can be replaced by corresponding faster and slower ones Rotation of the toy can be generated. At a slower speed, the bubbles tend to get bigger. Many fully formed Bubbles stick together.

From the foregoing it will be seen that the present invention provides a bubble generating toy and method there are many advantages.
