BACKGROUND OF THE INVENTION 
The present invention relates to a bubble blowing toy for blowing a 
solution into bubbles, and more particularly to a bubble blowing toy which 
is adapted to blow a solution into big bubbles. 
A regular bubble blowing toy is generally comprised of a container holding 
a solution, and a bubble coil with a handle for blowing the solution into 
bubbles. Because the solution container is not convenient to be held by 
hand, the contained solution tends to be forced out of the solution 
container during playing. "Bubble Blowing Toy" of U.S. Pat. No. 5,183,428, 
which was issued to the present inventor, eliminates the aforesaid 
problem. According to U.S. Pat. No. 5,183,428, the bubble coil has the 
shape of a sword, and the solution container has the shape of a sheath 
adapted to receive the bubble coil. When the bubble coil is pulled out of 
the solution container and moved with the hand in the air, bubbles are 
produced. However, because the mouth of the sheath-like solution container 
is limited, the size of the bubble coil is limited too. In order to 
produce big bubbles, the size of the bubble coil must be relatively 
increased. "BUBBLE TOY WITH FLEXIBLE BUBBLE COIL" of U.S. Pat. No. 
5,653,620, which is also an invention of the present inventor, provides a 
bubble toy with a flexible bubble coil. Because the bubble coil is 
flexible, it can be made having a relatively bigger size for blowing big 
bubbles. 
SUMMARY OF THE INVENTION 
The present invention provides a bubble blowing toy specifically designed 
for blowing a solution into big bubbles. According to one embodiment of 
the present invention, the bubble blowing toy comprises a solution 
container holding a solution, and a bubble blowing device adapted to take 
up the solution from the solution container and to let the received 
solution be blowing into a big bubble. The bubble blowing device comprises 
a hand grip at one end, an elongated solution take-up arm connected to the 
hand grip, and a shutter means pivoted to the solution take-up arm, the 
solution take-up arm comprising an elongated arm body and a neck connected 
between the arm body and the hand grip, the shutter means comprising two 
shutter arms coupled together, the shutter arms each having a first end 
respectively pivoted to two opposite ends of the arm body of the solution 
take-up arm by pivot means and a second end pivoted to each other by a 
slip joint. The arm body of the solution take-up arm and the shutter arms 
of the shutter means each have a serrated portion longitudinally disposed 
at an inner side for efficiently taking up the solution from the solution 
container. Alternatively, the arm body can be covered with a sleeve having 
a coarse outside wall, or an outside wall with grains on it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, a bubble blowing toy in accordance with the present 
invention is generally comprised of a bubble blowing device 1, and a 
solution container 2. The solution container 2 has an opening 21 at one 
end of the elongated container body thereof, and holds a solution on the 
inside. 
Referring to FIGS. 2 and 3 and FIG. 1 again, the bubble blowing device 1 is 
comprised of a hand grip 11 at one end, an elongated solution take-up arm 
12, and shutter means 13 pivoted to the solution take-up arm 12. The 
solution take-up arm 12 is fixedly connected to the hand grip 11, 
comprising an elongated arm body 121, a neck 122 connected between the arm 
body 121 and the hand grip 11, and two lugs 14 integral with two opposite 
ends of the arm body 121. The neck 122 keeps the arm body 121 away from 
the hand grip 11, enabling the arm body 121 and the shutter means 13 to be 
completely dipped in the solution when the bubble blowing device 1 is 
closed and inserted through the opening 21 into the solution container 2. 
The arm body 121 has a serrated portion 1211 longitudinally disposed at 
one side for taking up the bubble solution from the solution container 2 
efficiently. 
The shutter means 13 can be variously embodied. In FIGS. from 1 through 6, 
the shutter means 13 is shown comprised of two shutter arms 131 coupled 
together. The shutter arms 131 each have a serrated portion 1311 
longitudinally disposed at one side facing the serrated portion 1211 of 
the arm body 121 of the solution take-up arm 12, a first end respectively 
pivoted to the lugs 14 at the solution take-up arm 12 by a respective 
pivot 141, and a second end coupled to each other by a slip joint. The 
slip joint is comprised of an elongated slot 1313 longitudinally provided 
at the second end of one shutter arm 131, and a pivot 1312 fixedly 
fastened to the second end of the other shutter arm 131 and moved in the 
elongated slot 1313. 
Referring to FIGS. 9 and 10, the shutter means 13' is shown comprised of 
two pivoting arms 131', and a guide arm 132'. The guide arm 132' is 
disposed in parallel to the arm body 121 of the solution take-up arm 12, 
having a serrated portion 1321' longitudinally disposed at one side facing 
the serrated portion 1211 of the arm body 121 of the solution take-up arm 
12 and two longitudinally aligned sliding slots 1322'. The pivoting arms 
131' each have one end respectively pivotably connected to the lugs 14 at 
the solution take-up arm 12 by a respective pivot 141, an opposite end 
respectively movably coupled to the sliding slots 1322' of the guide arm 
132' by a respective pivot 1312', and a serrated portion 1311' 
longitudinally disposed at an inner side facing to each other. When the 
shutter means 13' is opened, the guide arm 132' with the pivoting arms 
131' and the arm body 121 of the solution take-up arm 12 define a space 
for suspending a bubble solution membrane for blowing into a big bubble. 
Referring to FIGS. from 1 through 3 and FIGS. 9 and 10 again, when the 
shutter means 13 or 13' is closed, it is closed attached to the solution 
take-up arm 12, enabling the bubble blowing device 1 is closed and 
inserted through the opening 21 into the solution container 2 to take up 
the bubble solution. When the bubble blowing device 1 is removed from the 
solution container 2 and the shutter means 13 or 13' is opened, a bubble 
solution membrane is suspended in the space defined by the solution 
take-up arm 12 and the shutter means 13 or 13' for blowing into a big 
bubble. 
Referring to FIGS. 3 and 10 again, when the bubble blowing device 1 is 
removed from the solution container 2, it is held in horizontal and 
rotated, enabling the shutter means 13 or 13' to be suspended from the 
solution take-up arm 12 at the bottom. When the shutter means 13 or 13' is 
turned to the bottom side, it is immediately forced by its gravity weight 
to move to the opened position. On the contrary, when the shutter means 13 
or 13' is turned to the top side above the solution take-up arm 12, it 
immediately returns to the closed position. 
Referring to FIGS. from 4 through 6, when a bubble solution membrane is 
suspended in the space within the shutter means 13 and the arm body 121 of 
the solution take-up arm 12, the bubble blowing device 1 is moved in the 
air by hand, causing the bubble solution membrane to be blown into a big 
bubble. 
Referring to FIG. 7, two shutter means 13 may be symmetrically pivoted to 
the lugs 14 of the solution take-up arm 12 for producing two big bubbles 
at a time. According to this embodiment, the opening 21 of the solution 
container 2 must be made relatively bigger. 
Referring to FIG. 8, the bubble blowing device 1 is comprised of a hand 
grip 11 at one end, an elongated solution take-up arm 12', and shutter 
means 13 pivoted to the solution take-up arm 12'. The solution take-up arm 
12' is a round rod fixedly connected to the hand grip 11, comprising an 
elongated arm body 121', a neck 122' connected between the arm body 121' 
and the hand grip 11, and two barrel 14' mounted on the arm body 121' and 
retained to the two opposite ends of the arm body 121' by locating means 
142'. The shutter means 13 is pivoted to the barrels 14' by pivots 141'. 
The arm body 121' is covered with a sleeve 1211' having a coarse outside 
wall. The operation of this embodiment is similar to the embodiment shown 
in FIGS. from 1 through 6.
