This invention relates to a bubble forming device and more especially to an apparatus hav ng a container with a fiat member movably supported by the container and havin an opening therethrough normally held immersed in a bubble forming solution within the flat member and being movable longitudinally of the container and out of the container to expose the flat member above the top of the container in a position where a stream of air can be blown through the opening to form a plurality of bubbles, said flat member having integral therewith a cover portion for the container with tension means normally moving the fiat member to immersed position within the container and to hold the lid or cover portion associated with the fiat member in close contact with the upper open end of the container to prevent leakage of a bubble forming solution from th container.

It is an object of this invention to provide a bubble forming device comprising a container with a flat wand member slidably mounted relative to the container and having spring means normally holding the flat member encased within the container and said flat member having integral therewith a stopper or closure member which is adapted to be held over the upper open end of the container for closin the container when the flat member is housed within the container.

It is another object of this invention to provide a bubble forming device having a wand member immersible in a container and said wand member having a means associated therewith for retaining and feeding additional bubble forming solution to the opening in the wand member to thus effectively increase the duration of time during which bubbles may be continu ously blown from the wand member by the passing of a stream of air through the opening in the wand member.

Some of the objects of the invention havin been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which Figure 1 is an elevation of a preferred embodiment of the invention and showing it in normal closed position;

Figure 2 is an elevation similar to Figure 1 but ShOWlIlg the flat wand member moved out of the container in which it is normally encased;

Figure 3 is a vertical sectional view taken along the line 3-3 in Figure 1;

Figure 4 is a top plan view looking down on Figure 1; l

Figure 5 is a sectional plan view taken alon the line 5-5 in Figure 2;

Figure 6 is a sectional plan View taken along the line 6-6 in Figure 2;

Figure 7 is an elevation of a modified form of a bubble forming apparatus;

Figure 8 is an elevation similar to Figur '7 but showing the wand and cover member raised relative to the container in which it is normally housed;

Figure 9 is a vertical sectional view taken alon the line 9-9 in Figure 7;

Figure 10 is a top plan view taken long the line [lb-Hi in Figure 7 Figure 11 is a sectional plan view taken alon the line I l-| in Figure 8.

Referring more specifically to the drawings, the numeral it indicates a container havin an imperforate bottom therein having a bottom flange H and a top flange [2 and vertical ribs [3 and M extending vertically along the outer surface of the container which have longitudinal bores extending therethrough for the reception of a substantially U-shaped member IS. The legs of this U-shaped member I5 are slidably mounted in the bores in the rib members [3 and I4 and surrounding each of the legs and disposed between the closed end of the U-shaped member [5 and the bottom of the container iii are coiled springs I! and [8 for normally holding the U-shaped member in the position shown in Figure 1.

The upper ends of the U-shaped member 15. after the U-shaped member has been installed in the bores in the ribs l3 and M, are turned inwardly as at 2!) and 2! into suitable cavities in a cap or lid member 22. This cap or lid mem ber 22 has a suitable gasket 23 disposed around its lower surface for engagement with the top edge of the container l B to seal the same against loss of the bubble forming liquid within the corn tainer. The top 22 has integral therewith a flat vane like member 24 which has its side edges and lower end beveled as at 25, 26, 21, 28, 29 and 3B, and has an opening 3| therethroughl through which air may be blown as from the mouth of the user te form bubbles from a film deposited over the opening 3 I. v

The vane like member 24 has a plurality of grooves 35 in both sides thereof for retaining the bubble forming solution and the cap por tion 22 is also hollowed out'as at 35 and 31 to provide cavities for storing the bubble forming solution and to allow this bubble forming solution to flow downwardly from the

cavities

36 and 37 and the grooves 35 to continue to deposit a film of the bubble forming solution over the opening 3| to thus prolong the time interval during which bubbles may be produced from the device. The container is adapted to be substantially filled with a bubble forming solution indicated at 38. The vane like member 24 is beveled with round bevels as at 42 and 43 to provide a thin annular rib portion is from whence the film will be expelled by a blast of air. Regardless of the amount of bubble forming solution 38 disposed within the container Hi, the opening 3i will have a film deposited thereover and a reserve of the bubble forming solution will be deposited in the grooves 35 and the

cavities

36 and 37, since the device is usually turned on its side or upside down immediately prior to moving the parts from the position shown in Figure 1 to the position shown in Figure 2.

Figures 7 to 11 show a slightly modified form of the invention in which like reference characters indicate like parts, and only the matter differing from the structure shown in Figures 1 to 6, inclusive, will be described.

In this modified form of the invention, a container 5i) is provided which is spool-like in shape on its exterior to provide enlarged

portion

55 and 52 near its top and bottom to provide a suitable hand hold for the operator and to make the container 50 more easily gripped by a hand and to prevent sliding movement of the same in the hand of an operator. Instead of having the U- shaped rod 15 and associated parts, the bottom of the container 50 has a centrally disposed perforation 55 therein in which a suitable resilient grommet 55, preferably of rubber or synth tic rubber, is mounted and this grommet is penetra-ted by a plunger 56 having a knob 5'! on its lower end surrounded by a compression spring 52. The upper end of this rod 55 is threaded and the lower end of the vane like member 24 is bored and threaded for reception of the upper end of the rod 55.

The upper end of both containers l9 and 58 are beveled as at 6b to provide a more perfect seal between the gasket 23 and the beveled surface 56. All the other features shown in Fi ures 7 to 11 inclusive, which are identical to the features shown in Figures 1 to 6, inclusive, bear like reference characters, and additional description is not deemed necessary.

Method of operation With the parts in the position shown in Figures 1 and 7, the vane like members 2-; is expelled to the position shown in Figures 2 and 8, and the container ill or 59 is filled with a suitable bubble forming solution, and then the member E5 or 55 has the pressure released therefrom and the springs H and E8 or spring 58 move the parts to closed position as shown in Figures 1, 3, '7 and 9, and before bubbles are to be formed, the apparatus is turned on its side or, if desired, upside down, and then moved to the position shown in Figures 1 or 7 and then by pressure being applied to the member E5 or 56, the parts are moved to the position-shown in Figures 2 or 8 and a film of bubble forming solution will be formed over the opening 3| as well as deposited in the grooves 35 and the

cavities

36 and 31, and a sream of air will be blown from the mouth of an operator through the opening 3| which will form a plurality of bubbles from the film disposed over the opening 3!. As the bubble forming solution will feed over the opening 3! continuously to replace the bubble forming solution which is being consumed, it is seen that bubbles will be formed from the stream of air being forced through the opening 3i so long as the film deposited in the grooves 35 and the

cavities

35 and 37 continues to flow down to maintain the film over the opening 3|.

It is thus seen that this device provides means whereby the duration of time during which bubbles can be formed from a single operation will be doubled and even trebled and greatly increased from that of a wand having a film deposited thereover and which is soon exhausted by the blowing of a stream of air therethrough to form only a few bubbles.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purpose of limitation, the scope of the invention being defined in the claims.

I claim:
