Abstract
2086005 9202281 PCTABS00010 This invention relates to a device and a method for bubble blowing, comprising a tubular member (3) and, inside it, a surface (4) or several surfaces (11). The former widens in the direction of air flow, and the latter causes the airstream to narrow. The device in accordance with this invention is used to blow a large bubble and smaller bubbles inside the same and/or onto its side.
Description
W092/0228t 2 ~ ~ 6 ~ ~ ~ PCT/~91/00228 Device and method for blowing bubbles This invention relates to a device and a method for blowing bubbles. The device and the method are of the type given in the introductory part of the corresponding claim.
No doubt everybody has practised the art of blowing soap bubbles as a child. The conventional bubble-producing device consists, for example, of a piece of metal wire with one end bent around to form a loop. The loop is dipped in a solution of water and soap or detergent and the film which is retained acro~s the wire loop is inflated by blowing air onto it from the flat side. The bubble then floats off after having increased somewhat in size. This is a primitive device and is never sure to perform pxoperly;
even if it does, it will only form one bubble at a time.
A bubble-blowing apparatus familiar from US-Patsnt 3,323,250 consists of two short tubular members, one within the other, the inner member narrowing conically in the direction of the air flow. The front portion of the outer member is cylindrical and its rear portion is similarly conical where lt overlaps with said inner tube. Blowing is accomplished as an unobstructed breath of air directed into the device at some distance. The device in guesti.on allows the simultaneous formation of two bubbles, one within the other.
An obvious drawback of said device is the incertainty of its function as it no doubt calls for very skillful blowlng to achieve the desired result. The device has a rather complicated channel system, which in itself is rather difficult and expensive to fabricate and with which no bubbles are formed at all unless the air flow is directed accurately. On the other hand, dlrectlng the alr flow from the llps to the somewhat distant center of the device ls so WO 92/02281 r PCl'/F191/00228 2086~
imprecise that there is little hope of any fine control.
In the bubble-blowing device known from US Patent 3,473,253, the air is blown through an aperture in a diagonal wall which remains submerged in soapy water. The air forced out through the aperture will therefore flow up, forming a bubble which in turn exits into the ambient air through the opening provided in the device.
The function of the device is thus limited to producing a continuous row of bubbles and its operation is probably monotonous and hardly entertaining to the user for any longer periods due to the lack of variety. Furthermore, many of ~th'e''bubbles produced when air emerges from the soapy water are likely to burst when they strike the edge of the device or at least when the bubbles are squeezed through the exlt passageway with the outflowing air, whereupon -- concluding from the description given -- they are forced to assume a new form.
Other devices than those referred to above have been developed for bubble-blowing. For example, US Patent

Other devices than those referred to above have been developed for bubble-blowing. For example, US Patent
2,628,44,9 presents an apparatus in which a "flywheel"

A narrow jet of air directed from a special blowing part inflates and releases a bubble from each ring quite analogous to the preceding one. At the same time, the alr flow keeps the ~flywheel" rotating. The result is thus a sequence of isolated bubbles.

5 the relationship of the cross-section area of upstream end lO of inner tube 4 to the cross-section area of the outer tube at the corresponding level can be varied.
Instead that tube 4 would form only one outlet opening 6, lO it is possible to divide the outlet opening, in the direction of air flow, into several openings, for example by providing the outer end of tube 4 with a plate like stopper and by providing the same with openings of suitable ~ size and number. The bubbles formlng from these openings lS remain inslde mother bubble 8 as descrlbed before.
Figure 5 outlines the principle of an exemplary bubble-blowing device according to the second embodiment of the invention. It basically consists of two relatively long 20 tubular members 3. In this embodiment, part 3 contains a surface ll to split the air flow in tube 3 into two or more streams so that bubbles are produced at a minimum of two differe-.t openings. Surface ll corresponds to the inner cone 4 of the preceding embodiment.
In this embodiment, the bubble blower, ln a mode analogous to the principle of the preceding embodiment, places the r inlet opening 2 of tube 3 on his or her lips, having first dipped the outer end, in the direction of air flow, of the 30 tube in a solution of water and soap or detergent, and starts blowing. The air flow reaches surface ll, from where it is divided and led, through hole 12 in surface ll, into upper compartment 13 and when hitting surface ll, it is partially guided also into lower compartment 14. The 35 formation of the larger bubble, the so-called mother bubble, is initiated at opening 5 of upper compartment 13, and the holes 16 of lower compartment 14, which are . .

Because the area on the mother bubble where the slde-bubbles are attached ls indeed on the side of the mother bubble, air flow is accelerated by increasing the blowing force and because of the conical shape of the lower compartment 14 and the mother bubble begins to rotate, offering more surface area for the formation of new side-bubbles.
It should be noted, that also in a device according to this embodiment, it ls possible to discontinue the lnflating of the bubble at any point, as in the preceding embodiment.
Openings 16, from which the side-bubbles are sent off onto the side of the mother bubble, are at least one but preferably several in number and they can be of different sizes to enable the formation of side-bubbles varying in size.

Surface 11 and opening 12 are quite general terms for the configurations which can be used in accordance wlth the invention. The surface shown as an example in the cross-section Figures 6 and 7 features a cut at its upper edge, the cut representing the opening 12. However, it ls possible that opening 12, in fact, has been made so that surface 11 partially fails to meet the upper edge of tube 3 and is thus left incomplete. In other words, opening 12 no more has the shape seen in figures 6 and 7, but is shaped to remind, for example, the segment of a circle.
The shape of surface 11 is not essential. It can be flat or curved in any direction, or it can also be given a wavy or any other configuration. The surface design can be based on esthetic considerations rather than any given precondltions for its proper function.
': :,. ' WO92/02281 2 ~ ~ 6 0 a ~ PCTt~91/00228 The opening can be of any shape and it can be located, as seen in figures 6 and 7, at the edge of surface 11 but can also pierce it at any spot other than at the edge.
Actually, it is ~ust a matter OI splitting the air flow, so there are other ways than making an opening of accomplishing this, as will be explained later.
Instead of using a single surface 11 for air flow control, it is possible to use separate segmental surfaces, each of - 10 which guides its share of the air flow into lts own aperture 16. This enables a more accurate control of the partly streams of the air flow, although this, on the other hand, naturally involves a somewhat more complicated -- ~ construction than that seen in Figure 5.
The third embodiment of the invention is shown in Figure 9 as a side view corresponding to that in Figure 5 and, respectively, in Figure 10, as viewed directly inwards from the outer end of tube 3.
In the configurations in figures 9 and 10, three separate conical surfaces, 11a, llb and llc, have been used to collect air with their upstream ends 15 into the individual outlet openings 16, at each of which a side-bubble is produced. In this case, side-bubbles are produced from three openings 16, yet their number is not critical in any respect. Similarly, although in this particular case the truncated narrowing cones that direct air into the side-bubbles are disposed symmetrically across the cross-section of tube 3, an asymmetrical disposition will function ~ust as well. As a matter of fact the disposition can be chosen completely freely and is an esthetic rather than a technical consideration. It is also possible to alter the longitudinal disposition between tube 3 and surfaces lla, llb llc when needed. It ~s possible to make such an embodiment of the disposltion where part of the surfaces lla, llb, llc direct air approximately into the centrum of .
W O 92/02281 , ~ a s PC~r/F191/00228 the outlet of tube 3. Hereby smaller separate bubbles are blown inslde the mother bubble. This embodiment is thus a combination of the embodiment described first and the one described just above.
As shown, on the basis of the above embodiment, surface 11 may appear in many dif~erent ways and even consist of several entirely separated surfaces. The basic idea is that the surfaces serve to split the alr flow into one stream to lnflate the mother bubble and into another one or more streams to inflate side-bubbles. It is a further principle, that the side-bubbles are produced by narrowing airstreams.
The large bubble, so-called mother bubbie, is thus produced from opening 5 at the exit end of tube 3. Side-bubbles are inflated at the smaller openings 16 and adhere to the sides ;;~
of the mother-bubble. The output is illustrated in Figure 11, showing a mother-bubble 17 and a great number of side-bubbles 18. As soon as the desired end result has been achieved, the group of bubbles is put afloat by a sideways movement of tube 3.
As is clearly seen in the ifigures, tube 3 is at least slightly widening in the downstream direction. The tubular member 3 ls conveniently provided as a truncated cone. On the other hand, the air channels through which the side-bubbles are inflated are slightly narrowing and they, too, for example, can be truncated cones in configuration.
Although in this embodiment, by way of an example, tube 3 has been shown to have a round cross-section, even here this is in no way essential, but any desired form can be used. Thus, a sguare or hexagon cross-section is convenient. Where needed, an indefinite cross-section can also be used.
As stated, the members to fit lnside tube 3 can also be, WO92/02281 ~ ~ 3 ~ PcTtn9l/00228 when necessary, removeable and interchangeable. Thls enables a construction that allows a very wide varlety of different soap-bubble formations to be produced simply by changing the tube's interior fittings for other ones, whereby the slze o~ the diameters of opening 12, the upstream end 15 of conical surfaces lla, llb, llc and outlet openings 16 can be freely changed. Hereby it is possible to blow a great variety of bubbles, even so that it is obtained a bubble construction, containing a mother bubble and lnside the same there floats freely separate bubbles 9 and a group of bubbles formed of inner bubbles 18. Wlth the form of tube 3 and by choosing a æuitabla combination solution from the above matters it is possible -~-~ to obtain excellent reliability of the devicé as the personal skill and bLowing force of the user can be exploited.
It is to be mentioned furter that even though it has been talking above about a soap-bubble, lt ls to be understood that any solution corresponding to a soap solution is useful for the purposes of this invention. So, one suitable solution is formed by adding to water detergent used for making dishes by hand.

Instead that tube 4 would form only one outlet opening 6, lO it is possible to divide the outlet opening, in the direction of air flow, into several openings, for example by providing the outer end of tube 4 with a plate like stopper and by providing the same with openings of suitable ~ size and number. The bubbles formlng from these openings lS remain inslde mother bubble 8 as descrlbed before.
Figure 5 outlines the principle of an exemplary bubble-blowing device according to the second embodiment of the invention. It basically consists of two relatively long 20 tubular members 3. In this embodiment, part 3 contains a surface ll to split the air flow in tube 3 into two or more streams so that bubbles are produced at a minimum of two differe-.t openings. Surface ll corresponds to the inner cone 4 of the preceding embodiment.
In this embodiment, the bubble blower, ln a mode analogous to the principle of the preceding embodiment, places the r inlet opening 2 of tube 3 on his or her lips, having first dipped the outer end, in the direction of air flow, of the 30 tube in a solution of water and soap or detergent, and starts blowing. The air flow reaches surface ll, from where it is divided and led, through hole 12 in surface ll, into upper compartment 13 and when hitting surface ll, it is partially guided also into lower compartment 14. The 35 formation of the larger bubble, the so-called mother bubble, is initiated at opening 5 of upper compartment 13, and the holes 16 of lower compartment 14, which are . .

Because the area on the mother bubble where the slde-bubbles are attached ls indeed on the side of the mother bubble, air flow is accelerated by increasing the blowing force and because of the conical shape of the lower compartment 14 and the mother bubble begins to rotate, offering more surface area for the formation of new side-bubbles.
It should be noted, that also in a device according to this embodiment, it ls possible to discontinue the lnflating of the bubble at any point, as in the preceding embodiment.
Openings 16, from which the side-bubbles are sent off onto the side of the mother bubble, are at least one but preferably several in number and they can be of different sizes to enable the formation of side-bubbles varying in size.

Surface 11 and opening 12 are quite general terms for the configurations which can be used in accordance wlth the invention. The surface shown as an example in the cross-section Figures 6 and 7 features a cut at its upper edge, the cut representing the opening 12. However, it ls possible that opening 12, in fact, has been made so that surface 11 partially fails to meet the upper edge of tube 3 and is thus left incomplete. In other words, opening 12 no more has the shape seen in figures 6 and 7, but is shaped to remind, for example, the segment of a circle.
The shape of surface 11 is not essential. It can be flat or curved in any direction, or it can also be given a wavy or any other configuration. The surface design can be based on esthetic considerations rather than any given precondltions for its proper function.
': :,. ' WO92/02281 2 ~ ~ 6 0 a ~ PCTt~91/00228 The opening can be of any shape and it can be located, as seen in figures 6 and 7, at the edge of surface 11 but can also pierce it at any spot other than at the edge.
Actually, it is ~ust a matter OI splitting the air flow, so there are other ways than making an opening of accomplishing this, as will be explained later.
Instead of using a single surface 11 for air flow control, it is possible to use separate segmental surfaces, each of - 10 which guides its share of the air flow into lts own aperture 16. This enables a more accurate control of the partly streams of the air flow, although this, on the other hand, naturally involves a somewhat more complicated -- ~ construction than that seen in Figure 5.
The third embodiment of the invention is shown in Figure 9 as a side view corresponding to that in Figure 5 and, respectively, in Figure 10, as viewed directly inwards from the outer end of tube 3.
In the configurations in figures 9 and 10, three separate conical surfaces, 11a, llb and llc, have been used to collect air with their upstream ends 15 into the individual outlet openings 16, at each of which a side-bubble is produced. In this case, side-bubbles are produced from three openings 16, yet their number is not critical in any respect. Similarly, although in this particular case the truncated narrowing cones that direct air into the side-bubbles are disposed symmetrically across the cross-section of tube 3, an asymmetrical disposition will function ~ust as well. As a matter of fact the disposition can be chosen completely freely and is an esthetic rather than a technical consideration. It is also possible to alter the longitudinal disposition between tube 3 and surfaces lla, llb llc when needed. It ~s possible to make such an embodiment of the disposltion where part of the surfaces lla, llb, llc direct air approximately into the centrum of .
W O 92/02281 , ~ a s PC~r/F191/00228 the outlet of tube 3. Hereby smaller separate bubbles are blown inslde the mother bubble. This embodiment is thus a combination of the embodiment described first and the one described just above.
As shown, on the basis of the above embodiment, surface 11 may appear in many dif~erent ways and even consist of several entirely separated surfaces. The basic idea is that the surfaces serve to split the alr flow into one stream to lnflate the mother bubble and into another one or more streams to inflate side-bubbles. It is a further principle, that the side-bubbles are produced by narrowing airstreams.
The large bubble, so-called mother bubbie, is thus produced from opening 5 at the exit end of tube 3. Side-bubbles are inflated at the smaller openings 16 and adhere to the sides ;;~
of the mother-bubble. The output is illustrated in Figure 11, showing a mother-bubble 17 and a great number of side-bubbles 18. As soon as the desired end result has been achieved, the group of bubbles is put afloat by a sideways movement of tube 3.
As is clearly seen in the ifigures, tube 3 is at least slightly widening in the downstream direction. The tubular member 3 ls conveniently provided as a truncated cone. On the other hand, the air channels through which the side-bubbles are inflated are slightly narrowing and they, too, for example, can be truncated cones in configuration.
Although in this embodiment, by way of an example, tube 3 has been shown to have a round cross-section, even here this is in no way essential, but any desired form can be used. Thus, a sguare or hexagon cross-section is convenient. Where needed, an indefinite cross-section can also be used.
As stated, the members to fit lnside tube 3 can also be, WO92/02281 ~ ~ 3 ~ PcTtn9l/00228 when necessary, removeable and interchangeable. Thls enables a construction that allows a very wide varlety of different soap-bubble formations to be produced simply by changing the tube's interior fittings for other ones, whereby the slze o~ the diameters of opening 12, the upstream end 15 of conical surfaces lla, llb, llc and outlet openings 16 can be freely changed. Hereby it is possible to blow a great variety of bubbles, even so that it is obtained a bubble construction, containing a mother bubble and lnside the same there floats freely separate bubbles 9 and a group of bubbles formed of inner bubbles 18. Wlth the form of tube 3 and by choosing a æuitabla combination solution from the above matters it is possible -~-~ to obtain excellent reliability of the devicé as the personal skill and bLowing force of the user can be exploited.
It is to be mentioned furter that even though it has been talking above about a soap-bubble, lt ls to be understood that any solution corresponding to a soap solution is useful for the purposes of this invention. So, one suitable solution is formed by adding to water detergent used for making dishes by hand.
