DEVICES FOR PRODUCING BUBBLES Filed March 26, 1962 ZSheets-Sheet 1 g n 4III/I/I/II/IIIII I 8 FIG. 5 FIG. 6

Vm/T 2 g! lfe a by Nov. 5, 1963 DEVICES FOR PRODUCING BUBBLES Filed March 26, 1962 2 Sheets-Sheet 2 WdapZf {mar United States Patent DEVICES FOR PRODUCING BUBBLES Rolf Hein, Gartenstrasse 85, Tuebingen, Germany Filed Mar. 26, 1962,Ser. No. 182,188 15 Claims. (Cl. 46

The present invention relates to devices for producing bubbles.

More particularly, the present invention relates to that type of device wherein the user immerses a ring in a solution from which bubbles are adapted to be formed, and when withdrawn from the solution a film of the solution extends across the ring so that the user, when blowing through the ring, will form a bubble from the film.

Devices of this general construciton are well-known, and they take the form of rings or loops which are formed of'non-porous material such as wire or plastic. These known devices, however, have a serious drawback in that only a limited number of bubbles can be formed each time the ring is withdrawn from the solution. As a general rule only one, and sometimes two bubbles may be formed each time the ring or loop is withdrawn from the solution, so that the user must necessarily continuously immerse the device into the solution repeatedly in order to keep producing the bubbles.

Moreover, another drawback of the known devices of the above type resides in the fact that it is not possible for thesolution tobe used entirely. There will alwaysv remain, with the known constructions, a residual part of the solution in the bottom of the container therefor, and it is not possible to make bubbles from this last remaining portion of the solution.

One of the objects of the present invention is to provide a bubble-forming device which will be capable of producing from each immersion a number of bubbles far in excess of the number which can be formed from conventional devices of the type referred to above.

Another object of the present invention is to provide a device for the above type which is exceedingly simple and inexpensive to manufacture.

A further object of the present invention is to provide in a bubble-producing device a container which cooperates with the device inserted into a solution in the container in such a way that practically all of the solution can be used in order to form bubbles.

With the above objects in view the invention includes, in a device for producing bubbles, a body which is adapted to be immersed in a solution from which bubbles are adapted to be formed, this body being formed with an opening across which a film of the solution extends when the body is withdrawn from the solution. Thus, the operator, upon blowing through the opening, will form a bubble from this film. In accordance with the invention, the body has an endless portion surrounding the opening thereof and having an inner periphery which defines this opening, and this endless portion is formed with a plurality of capillary passages which extend all the way up to the inner periphery of the endless portion so as to communicate with the opening of the body. Because of these capillary passages, additional solution is stored in these passages and will flow to the inner periphery of the endless portion as successive bubbles are formed, so that in this way it becomes possible to form many more bubbles than would be the case where the body was incapable of storing solution which would automatically flow to the inner periphery of the endless portion to form additional bubbles.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be 3,109,255 Ce Patented Nov. 196? 2. best understood from the following description of specific embodiments when read in connection with the ac companying drawings, in which:

FIG. 6 is a sectional plan view of the structure of FIG. 5 taken along line VI-VI of FIG. 5 in the directionof the arrows; 7

FIG. 7 is a sectional elevation illustrating one form of container and bubble-producing device according to the present invention;

FIG. 8 is a sectional elevation illustrating another bodiment of a container and bubble-forming device according to the present invention;

FIG. 9 illustrates another variation of a bubble-forming device according to the invention; and

FIG. 10 is a transverse section of still another embodiment of a bubble-forming device according to the present invention.

Referring now to FIGS. 1-3, there is shown therein an annular :body 1 which is adapted to be immersed in a solution, such as a soap solution, from which bub-bles are adapted to be formed, as is well-known. The body 1 is formed with an opening 2, and the size of the opening 2 and the nature of the solution into which the body 1 is immersed are such that when the body 1 is removed from the solution, there will extend across the opening 2, as a result of the surface tension of the liquid which forms the solution, a film of the solution, so that the operator, upon blowing through the opening 2, will form a bubble from this film, as is well-known. The annular body 1 may be connected to a stern, shown at the lower part of FIG. 1, which enables the operator to manipulate the body 1, this stern forming a handle, as is also well-known. The annular body 1 forms an endless portion which surrounds the opening 2 and has an inner periphery which defines the opening 2. At its opposed faces the body 1 is formed with a plurality of radial grooves 4, and these grooves extend all the way up to the inner periphery 3 of the endless portion which surrounds the opening 2. The several grooves 4 on each of the opposed faces of the body 1 are of such a width, that they have a capillary action with respect to the solution, so that solution is stored in the several grooves 4. Thus, the several grooves 4 form passages which communicate with the opening 2 at the inner periphery 3 of the body 1. -As the successive bubbles are formed the solution which is stored in the passages 4 'will flow toward the inner periphery 3 of the -body 1 so that in this Way it is possible to form, after each immersion of the body 1 in the solution, a number of bubbles far in excess of that which could be formed if the exterior surface of the body 1 were smooth.

The body 1 is also formed in each of its opposed faces with an annular groove 5 whose center coincides with the center of the circular opening 2, and this groove 5 extends across all of the radial grooves 4, so that in this Way all of the grooves 4 communicate with each other, and

the several grooves 4. In addition, the body 1 is formed at its inner periphery 3 with a plurality of axially extending notches 6. The grooves 4 on one face of the body 1 are respectively aligned with the grooves 4 on the opposite face of the body 1, and the several notches 6 provide communication between the pairs of aligned grooves 4, as is particularly apparent from FIG. 3, so that in this way also a uniformity of the supply of solution to the inner periphery of the body '1 is enhanced.

A particular feature of the present invention resides in the fact that eachof the grooves 4 is tapered so that it becomes narrower as it approaches the inner periphery 3 of the body 1. As a result of this feature, not only will the flow of solution in the passages 4 toward the inner periphery 6 be augmented as a result of the capillary action itself which tends to draw the liquid toward a narrower part of each groove 4, but in addition it is possible to uniformly distribute the several grooves 4 about the center of the opening 2, so as to provide a uniform delivery of the solution and thus provide a great number of successive bubbles after each immersion of the body 1 in the solution. With certain known constructions, as where the ring is in the form of a coiled wire or the like or Where the ring is formed from a plurality of wires which are twisted together, it is of course also possible to store in the ring solution in additio-n toithat which would be located onthe surface of a smooth ring, but with these latter constructions the solution will by gravity always flow to the lowest part of the ring so that it is not possible to unifonmly deliver the solution to the inner periphery of the ring to form a large number of successive bubbles. However, with the structure of FIGS. 1-3, the capillary action provided by the several grooves will prevent the solution from flowing t the lowest part of the device, so that uniform delivery of the solution about the entire inner periphery 3 of the body '1 is guaranteed.

The embodiment of the invention which is illustrated in FIG. 4 is also in the form of a ring which is provided at its opposed surfaces with a plurality of radial and annular grooves of such a size that by capillary action solution will be stored in these grooves. As may be seen from FIGv 4, the endless portion of the body which surrounds the opening 2 is circular, for example, in crosssection, and at the intersections of all of the radial and circumferential grooves are located a plurality of pins 7, so that these pins 7 serve to decline a plurality of radial and circumferential grooves or passages, and the spacing of the pins 7 is such that by capillary action these circumferential and radial passages will retain therein a supply of solution which will uniformly flow to the inner periphery of the annular body to provide a large number of bubbles. The pins 7 may be formed integrally with the remainder of the annular body, and all of this material may be made of plastic and formed in a suitable mold, for example, and in the case of FIGS. l-3 also the body l may be formed of a suitable plastic in a suitable mold.

Referring to 'FIGS. and 6, the device of FIGS. l-3 may be immersed in a solution which is located Within a container 8 as shown in FIGS. 5- and 6. This container 8 is in the form of a simple hollow cylinder, and, as is particularly apparent from FIG. 6, the transverse curvature of the body 1 is such that it conforms to the curvature of the inner surface of the cylindrical side wall of the container 8, so that the outer side surface of the body 1 can be located in its entirety against the inner surface of the side wall of the container 8, as shown in FIG. 6, and in this way it is possible to place the capillary passages of the body 1 in communication with the very last drop of solution in the container 8, so that it is possible to form bubbles from all of the solution which is in the container 8 as a result of this feature of the invention.

According to the embodiment of the invention which is illustrated in FIG. 7, the container 9 is also cylindrical and is adapted to be closed by a cover 10. The body 11 which is used to form the bubbles may have the construction described above in connection with FIGS. 1-3, for example. The body 11 is fixed to one end of a stem 12 the opposite end of which is fixed to the cover 10, and the stem 12 may be formed integrally with the body 11, for example. The-upper end of the stem 12, as viewed in FIG. 7, can be fixed to the cover 10 in any suitable way. Thus, as is apparent from FIG. 7, it is possible to store the body 11 within the container 9 when the body 11 is not in use, simply by closing the container 9 with the cover 10. In accordance with the invention, the. container 9 is formed at its lower interior portion with a substantially funnel-shaped wall 13 communicating with a bottom recess 14 which is capable of receiving the entire body 11 with only a slight clearance, so that in this way the last remaining bit of solution which is located at the bottom of the recess 14 will be received by capillary action in the passages of the body 11 so as to be capable of being used for forming bubbles in the manner described above.

As is apparent from FIG. 7, the cover 10 is formed with an inner flange which is annular and which surrounds the portion of the cover 10 to which the stem 12 is fixed, so that in this way a recess 15 is formed, and when the body 11 is removed from the container 9 and positioned so that it is located at an elevation higher than the recess 15, any excess solution will flow down along the stem 12 into the recess 15 to be received therein so that in this way none of the solution is wasted. Also, any drops which fall from the body 11 will be received in the recess 15, the latter normally being located beneath the body 11 when the latter is used.

According to the embodiment of the invention which is -'-1ll-ustr'a=ted in FIG. 8, the annular body 16 also has the construction described above and shown in FIGS. 1-3, for example. This body 16 is located at its underside against the inclined bottom wall 17 of a cylindrical container 18. The upper portion of the stem 21, which is fixed to the body 16, has an enlargement 20 received in a suitable recess of a portion of the cover 19 so as to be fixed to the cover 19, and the stem 12 may be fixed to the cover 10 in the same way, and it will be noted that in the embodiment of FIG. 8 the connection of the stem 21 to-the cover 19 is eccentrically spaced from the center of the cover 1 9 which is used to close the container 18.

It is apparent that with the embodiment of FIG. 8 also the body 16 will extend to the lowest part of the con-J tainer so as to enable practically all of the solution to be received in the capillary grooves and thus to be ca- 7 pable of being used for forming bubbles.

Either the container for the solution or the bubbleforming body itself may be made of a flexible material so that in this way also it is possible to make use of the.

last bit of the solution in the container. If the materials used for the embodiments of FIGS. 7 and 8 are not flexible, then there will be located at the adjoining portions of the container and cover of the embodiment of FIG. 7

as well as that of FIG. 8 either a mechanicalior opticalv .ing of the cover with respect to the container, or one of these elements may be formed with a notch which receives a projection of the other element so as to mechanical-1y guarantee that the parts are in proper angular alignment to locate the body :11 in the recess 14 or the body 16 on the inclined wall 17, as shown in FIGS. 7 and 8, respectively.

"The several radial capillary passages need not be.

straight. Moreover, the central opening of the body need not be circular and need not necessarily be positioned at the precise center of the body. For example, FIG. 9 shows a body 22 formed with an opening 23 across which a film of the solution will extend so that the operator can form bubbles by blowing through the opening 23. The endless portion of the body 22 which surrounds the opening 23 and which has an inner periphery which defines the opening 23 is formed with capillary passages as described above in connection with FIGS. 1-3 or in connection with FIG. 4. As is apparent from 'FIG. 9, the outer periphery of the body 22 may have a configuration which represents a living creature such as an animal. This effect of representing a living creature may be enhanced by suitable additional markings provided on the body 22, as indicated in FIG. 9. This form of construction renders the device far more attractive to a child.

In the embodiment of the invention which is illustrated in FIG. 10, the structure is exactly the same as that described above and shown in FIGS. 1-3, the only difference being that in addition to the structure shown in FIGS. 1-3, the embodiment of FIG. 10 includes a pair of layers 20 of foam plastic which are fused to the exterior opposed side surfaces of the annular body 1, each of these layers 20 being in the form of a ring of plastic which extends only between the inner and outer peripheries of the body 1. The foam plastic is preferably flexible and of the open-cell type, so that all of the cells communicate with each other, and in this Way it is possible to store in the foam plastic additional solution which will flow from the pores or cells of the foam plastic into the capillary passages and from the latter to the inner periphery of the body, as described above.

It should also be noted that in addition to being formed with notches =6 as indicated in FIGS. 2 and 3, the body 1 may also be formed with openings passing therethrough at the intersections of the grooves 4 and 5, so that in this way also the several grooves 4 at the opposed faces of the body 1 will be placed in communication with each other to further enhance the uniform supply of the solution to the inner periphery 3 of the body 1.

The use of plastic for the body 1 is preferred because it is inexpensive to manufacture and because it is resistant to corrosion, but it is also possible to use materials such as glass, metal, or the like that are non-porous.

In practice, it has been found that the grooves of passages 4 and 5 may have a width of from 0.53.0 mm. in order to provide the desired capillary action with respect to a soapy solution which is used to form the bubbles.-

Of course, these dimensions will vary with different solutions depending upon the surface tension ofthe liquid.

With soapy solutions grooves having a width of 3 mm.

of its manufacture.

It should be noted that bubble-producing devices which are blown through by children in order to form bubbles often pass from mouth to mouth so that there'is the possibility of spreading germs undesirably with these devices, particularly in the cases of small children. The struc ture of the invention, because of the manner in which the inner periphery of the body 1 is broken up by the grooves 4 and the notches 6, or by the pins 7 in the case of FIG. 4, greatly reduces the possibility of transferring germs, so that there is an additional safety factor involved with the structure of the invention.

It will be understood that each of the elements described above, or two or more together, may also find a They square cross-section is preferred because of the simplicity useful application in other types of bubble-producing devices differing from the types described above.

While the invention has been illustrated and described as embodied in bubble-producing rings and containers, it is not intended to be limited to the details shown, since various modifications and structural. changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspectsof this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
