Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to blowing bubbles, and more particularly to a manually operated mechanism capable of efficiently and consistently blowing bubbles.




2. Description of the Related Art




Simple devices and mechanisms are known in the art for blowing bubbles. A typical device includes a container usually formed of plastic and having a screw on cap. A soapy solution is held within the container that is used for blowing bubbles. The container usually comes with a wand that has a loop on one end. A user of the mechanism dips the wand in the solution of the bottle and then removes the wand from the bottle with a thin film suspended in the loop. The user then lightly blows air through the loop to releasing the suspended film of soapy solution to form one or more bubbles.




Other devices are known in the art that automatically create bubbles and are much more complex. These devices continually create bubbles in relatively large quantities. These types of bubble machines are relatively expensive, not particularly portable, and not suitable for occasional use by children and other non-commercial users.




The simple mechanism described above also has a number of problems associated with its use. First, a user must remove the cap from the bottle in order to use the mechanism. If a user drops or tips the bottle when in use, much or all of the solution is spilled and lost through the open top. The wand of this type of mechanism is simple in construction and includes a smooth surfaced and thin elongate portion and a thin loop attached to one end of the elongate portion. A user simply grasps the free end of the wand and manually dips the wand in the solution. The wand is separate from the bottle so a user will usually hold the wand in one hand and the bottle in the other. When blowing bubbles, excess solution dripping from the wand and loop is lost and not returned to the bottle. The wand can also be easily lost.




The cross sectional area of the wand and the loop portion is also typically relatively small. This type of wand cannot pick up a lot of the bubble foaming solution, both because the surfaces are smooth and because the surface area of the material is small. An additional problem with this type of mechanism is that the wand and loop are manually inserted into the opening of the bottle the user is holding the free end of the wand. Insertion of the wand into the bottle is random and can vary from one dip to the next. If the wand and loop are placed in the bottle at an angle it often happens that no soapy solution film is carried out by the loop because the angle forces solution through the loop as it is withdrawn from the bottle removing any film carried by the loop. The user must also aim the loop into the opening for each successive dip. This inhibits rapid, consistent and repeated dips.




SUMMARY OF THE INVENTION




What is needed is a bubble forming mechanism that is essentially as simple in construction and easy to use as the conventional bottle and wand construction. What is also needed is a bubble forming mechanism that is inexpensive to manufacture and assemble and is also very easy to transport by a user similar to the conventional bottle and wand construction. What is further needed is a bubble forming mechanism that can be easily used by children of young ages and yet consistently produce bubbles for their enjoyment. What is additionally needed is a bubble forming mechanism that consistently and efficiently produces bubbles and is capable of producing more bubbles at a faster rate than currently available manual and simple mechanisms. What is also needed is a bubble forming mechanism that will retain more of the soapy solution in the bottle or container and will also prevent or inhibit the solution from spilling if the container is dropped during use. What is additionally needed is a bubble forming mechanism that will retain the wand and loop positioned over the bottle. This returns solution dripping from the wand and loop into the bottle and prevents the wand from being lost.




Meeting these objects, features and advantages, a bubble forming mechanism is provided according to the present invention that includes a bottle for holding a bubble forming solution therein. A wand is provided that can be dipped into the bottle wherein the wand has a bubble-forming loop at one end. A slide is connected to the opposite end of the wand that is received through a guide carried on a portion of the bottle. A slot is provided in a top portion surface of the bottle and the wand and loop are received when solution is retrieved for forming bubbles.




These and other objects, features and advantages of the present invention will become apparent upon reviewing the detailed description and the accompanying drawing figures. The embodiments described herein are presented to illustrate the present invention and not to limit the present invention in any way.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to the drawings,

FIG. 1

illustrates a bubble forming mechanism


30


. According to the present invention, the bubble forming mechanism


30


includes a bottle or container


32


that is shaped to receive and contain a quantity of a bubble forming solution. The container


32


has a perimeter upstanding wall


34


and an enclosed bottom


36


. The bottle or container


32


has an open top into which solution can be added to the container


32


. The mechanism


30


also includes a container cap


38


that encloses a large majority of the open top of the container


32


. The bottle


32


and container cap


38


could be provided as a single uniform structure instead of two separable parts.




The mechanism of

FIG. 1

also includes a wand


40


having a loop


42


attached to the lower end of the wand


40


. In this embodiment, the loop


42


is integrally formed with the material of the wand


40


. The cap


38


or top of the container has a concave top surface forming a bowl or depression


44


in the cap. A receptor slot


46


is formed in the depression or concave surface


44


for receiving the loop


42


and the wand


40


therethrough. The slot


46


is specifically contoured and sized to correspond in length and width to the shape of the loop


42


.




Attached to the top end of the wand


40


is a slide


48


for manually lowering and raising the wand


40


and loop


42


into and out of the container


32


. For the mechanism


30


of

FIG. 1

, the slide


48


and the wand


40


are integrally connected by a curved section


50


so that movement of the slide


48


results in corresponding movement of the wand


40


. The slide


48


includes an elongate body


52


that extends downward and adjacent to the exterior of the container


32


. The lower end of the slide


48


includes another curved portion


54


that transitions into an upward extending handle or grip


56


. The handle


56


provides an easy surface for a user to grasp and operate the slide


48


. In the embodiment of

FIG. 1

, the handle


56


includes a surface relief


58


on one portion to assist in gripping the handle


56


and manipulating the slide


48


.




The mechanism of

FIG. 1

also includes a guide


60


that receives the slide


48


therethrough. The guide


60


supports and holds the slide


48


and hence the wand


40


relative to the container


32


. The guide


60


provides a through-opening


62


that closely corresponds to the shape and contour of the slide


48


so that the guide


60


accurately positions the slide


48


, and hence, the wand


40


relative to the container


32


even as the slide


48


is moved upward and downward through the guide


60


. This also prevents the wand


40


from being separated from the bottle


32


.




In the present embodiment, the guide


60


is carried as an integral portion on the cap


38


and extends outward beyond the exterior surface or perimeter wall


34


of the container


32


. A user of the mechanism


30


of

FIG. 1

can grip the surface relief


58


of the handle


56


and move the slide


48


in the direction of the arrows upward and downward relative to the container


32


.

FIG. 2

illustrates the slide


48


and wand


40


in an upward position wherein the wand


40


and loop


42


are withdrawn from the container


32


.

FIG. 3

illustrates the slide


48


in a lowered condition wherein the wand


40


and loop


42


are received in the container


32


. When the container


32


is filled with a bubble forming solution, an individual then moves the slide


48


from the withdrawn position of

FIG. 2

to the inserted position of FIG.


3


and then withdraws the wand


40


and loop


42


from the container


32


by moving the slide


48


back to the withdrawn position. By doing so, the loop


42


picks up a film of bubble forming solution. The user can blow through the loop


42


and form bubbles.




The slide


48


and guide


60


permit repetitive, accurate and consistent placement of the wand


40


and loop


42


in the container


32


to the same depth and at the same angle each time the mechanism


30


is used. Additionally, the handle


56


and slide


48


permit an individual to very quickly and repeatedly dip the loop


42


into the solution for forming a large quantity of bubbles at a very fast rate. The slide


48


and guide


60


also position the wand


40


and loop


42


directly over the slot


46


so that excess solution dripping from the wand


40


and loop


42


returns to the slot


46


. The curved top surface


44


also assists in directing the solution back to the slot


46


.




Referring to

FIG. 5

, an alternative embodiment of a bubble forming mechanism


64


is shown. The mechanism


64


includes a container


32


, cap


38


, wand


40


and loop


42


that are essentially identical to those disclosed in FIG.


1


. The guide


60


is also essentially identical and receives a slide


66


therethrough.




In this embodiment, the mechanism


64


includes a handle or grip


68


disposed at the top of the slide


66


near the transition or curved section


70


between the slide


66


and the wand


40


. As best illustrated in

FIG. 6

, when the slide


66


is in the upward or withdrawn position, no portion of the slide


66


extends below the cap


38


except for a stop


72


. The stop


72


is carried on the bottom end of the slide


66


and prevents the slide


66


from passing all the way through the guide opening


62


and being removed from the cap


38


.




As illustrated in

FIG. 7

, when the slide


66


is moved to the lowered or inserted position with the wand


40


and loop


42


received in the container


32


, the slide


66


does not extend below the bottom surface


36


of the container


32


. In this embodiment, the container


32


can rest on a flat surface even when the slide


66


is in the lowered position




In operation, the mechanism of

FIG. 5

operates identical to that for the mechanism


64


of

FIG. 1. A

user will grip the handle


68


and manipulate the slide


66


in order to insert and withdraw the loop


42


and wand


40


relative to the bottle


32


. In this embodiment, the grip


68


also includes a surface relief


74


for improving a user's grip on the slide


66


.




Another alternative embodiment of a bubble forming mechanism


76


is illustrated in FIG.


9


. In this embodiment, the container


32


, wand


40


and the loop


42


are essentially identical to those disclosed in the previous embodiments. The cap or cover


78


including the concave surface


44


and slot


46


is also essentially identical. However, the guide in this embodiment is different.




The cap


78


includes a pair of integral guide supports


80


carried on opposed sides of the cap


78


. A guide bracket


82


is in the form of an inverted U-shaped element having two parallel and opposed depending legs


84


interconnected at their top ends by a transverse segment


86


. The two legs


84


are each received in one of the guide supports


80


so that the guide bracket


82


is held spaced above the cap


78


. The guide bracket


82


also includes a slot


88


in the transverse segment


86


for receiving the wand


40


therethrough the loop


42


is carried on the bottom end of the wand


40


below the transverse segment


86


of the guide bracket


82


so that it can be inserted and withdrawn from the slot


88


. The top end of the wand


40


includes a handle or grip


90


having a surface relief


92


thereon. A coil spring


94


is received over the wand


40


and is sandwiched between the handle


90


and the guide element. The spring


94


acts as a return spring


94


and abuts against the top surface of the transverse segment


86


and the bottom surface of the handle


90


.




The slot


88


of the guide bracket


82


corresponds in size and shape to the size and shape of the wand


40


. The slot


88


in the guide bracket


82


also orients the wand


40


in such a manner that the loop


42


aligns correctly with the slot


88


and the cap


78


.





FIG. 10

illustrates the wand


40


and the loop


42


in a withdrawn position. A user simply places their hand on the handle or grip


90


and presses downward compressing the spring


94


to insert the loop


42


and wand


40


into the container


32


as illustrated in FIG.


11


. The user must simply relieve pressure on the handle


90


or release it all together so that the wand


40


is forced upward by the spring


94


to the withdrawn position as illustrated in

FIG. 12

after receiving a soapy solution film in the loop


42


. The construction of the mechanism


76


shown in

FIG. 9

including the return spring


94


permits an individual to repeatedly and very quickly and accurately insert and withdraw the wand


40


and loop


42


to form a large quantity of bubbles in a short period of time if so desired.





FIG. 13

illustrates another alternative embodiment of a bubble forming mechanism


96


. The mechanism


96


in this embodiment is similar to that described and shown in

FIG. 1

but includes a number of alternative features. The container


32


, cap


98


, slide


48


and guide


60


are virtually identical to those disclosed for the mechanism


30


of FIG.


1


. The cap


98


, however, includes two small additional features that are not shown in FIG.


1


.




The cap


98


has a protruding tang


100


extending therefrom near the guide


60


. The lower end of the slide


48


also includes a protruding tang


102


that generally corresponds in axial location to the tang


100


of the cap


98


. An elastic band


104


is received over each of the tangs


100


,


102


and retained thereon by tabs


106


,


108


oriented 90° relative to the respective protruding tangs and projecting away from one another. As an individual moves the slide


48


downward to insert the loop


42


and wand


40


into the container


32


, the elastic band


104


stretches and stores potential energy. When a user releases the slide


48


or releases some pressure on the slide


48


, the elastic band


104


will draw the slide


48


upward to the withdrawn position illustrated in FIG.


13


. The elastic band


104


acts as a return element that functions to permit repeated, accurate and quick repetitions of the bubble blowing process.




In this embodiment, the cap


98


also includes a protruding tab


110


that extends radially relative to the axis of the container


32


and is disposed opposite the guide


60


. A contoured flange


112


is provided on a portion of the wand


40


that also includes an interlocking lip


114


projecting and depending from the flange


112


. The interlocking lip


114


is received over to the tab


110


on the cap


98


when the slide


48


is in the lowermost position locking the slide


48


and the wand


40


within the container


32


. In this embodiment, the flange


112


is longer and wider than the slot


46


in the cap


98


and has a contour that follows the concave surface


44


of the cap


98


so that when the wand


40


is inserted in the bottle


32


, the flange


112


acts as a seal for the slot


46


in the bottle


32


.

FIG. 14

illustrates the cross section through the cap


98


and the wand


40


in a partial fragmentary view with the wand


40


in the lowered or inserted condition and the lip


114


and tab


110


interlocked.




Also in the embodiment illustrated in

FIG. 13

, the substantial portion of the wand


40


between the flange


112


and the loop


42


that extends into the bottle


32


when inserted is different. In the previous embodiments, the wand


40


was of an elongate rectangular cross section having a wide surface area that helps to guide the wand


40


into the slot


46


of the cap


98


and also helps to increase the surface area of the wand


40


and collect more bubble forming solution. In this embodiment, the wand


40


includes an elongate circular cross section portion connecting the loop to the flange


112


. This circular portion has a small diameter relative to the slide


48


and the remainder of the wand


40


. This circular portion also includes a helical or spiral protruding structure


116


extending along the wand


40


between the loop


42


and the flange


112


. This spiral structure


116


adds significantly more surface area to the wand


40


and also provides a downwardly spiraling surface


118


for additional bubble solution to drip on to the loop


42


. The spiral


118


assists in forming even more bubbles than in the previously described structures.




A number of different embodiments of the invention are described above. Each of these embodiments is provided to illustrate aspects of the present invention and not to limit the present invention in any way. Modifications and changes can be made to the described embodiments and yet fall within the scope and spirit of the present invention.
