Balloons are simple and traditional entertainment items for young children. However, inflating a balloon, especially orally, is not a simple task because air has a tendency to escape though the mouth of the balloon between bursts of inflation air or after inflation and prior to sealing the mouth. Therefore, it would be desirable to provide a device which eases balloon inflation.
Since balloons are typically novelty items, any features which provide added distinction are desirable. Providing lights within an otherwise plain balloon would be effective to add interest to the balloon. It would be desirable to provide an efficient, cost effective device for adding light to a balloon.
Briefly stated the invention provides a balloon inflation and air containment device. The device includes a first tube with a first end for receiving an air supply and a second end for receiving a mouth of a balloon. A collapsible second tube is connected to the first tube in a substantially airtight manner and extends away from the first tube. In one embodiment, a lighting device may be positioned inside the balloon.
Also provided is a method for constructing a balloon assembly. The method includes providing a tube assembly including a first tube and a collapsible second tube, axially connected to the first tube, which extends away from the first tube. A balloon is provided, and the tube assembly is axially inserted into a mouth of the balloon with the second tube leading into the balloon. The method includes providing an air supply at a first end of the first tube and inflating the balloon with the air supply. In one embodiment, a lighting device having an extension rod and a lighting element connected to the extension rod is provided. The lighting device is inserted through the tube assembly into an interior of the balloon.

Referring to
b shows how the sealing film tube 11 is mounted on the air filling pipe 10. The tube 11 is first slid onto a smaller-diameter end of the air filling pipe 10. Then, an adhesive tape 13 is wrapped around the surface of the pipe 10 with half of the tape applied to an outer surface of the pipe 10 and the other half applied to an edge of the tube 11. Any suitable adhesive tape may be used. The tape provides a very strong mounting joint between the tube 11 and the pipe 10. In order to achieve a better sealing joint, the length of the adhesive tape 13 should be greater than the circumference of the film tube 11 so that one end of the tape 13 overlaps with another end. This will ensure no air leakage. However, if the sealing film tube 11 fits the air filling pipe 10 very tightly, a shorter tape 13 can be used without affecting the seal because the connection between the film tube 11 and the filling pipe 10 will be tight enough to stop any leakage.
Referring to
On the bottom part of the supporter 12, there is an aperture which is placed over the air filling pipe 10 with the balloon skin disposed between, as seen in
Installation of the tube assembly 50 into the balloon is as follows. Referring to
The sealing film tube 11 on the air filling pipe 10 acts as a uni-directional valve which allows air to enter the balloon 20 during inflation, but prevents air from being expelled from the balloon when inflation is stopped. FIG. 8 shows a method of inflating the balloon using a foot pump 40 and tube 41. Alternatively, the balloon may be inflated using any method including orally blowing into the filing pipe 10, or using other air filling apparatuses.
a and 9b show how the sealing film tube 11 works as a uni-directional valve. When the air pressure P1 on the mouth of the air filling pipe 10 is higher than the air pressure P2 inside the balloon 20, air will flow into the balloon by passing through the center of the filling pipe 10 and the center of the sealing film tube 11. As air pressure inside the balloon 20 increases, the balloon 20 expands. When the air pressure P1 returns to atmospheric pressure for any reason, the pressurized air inside the balloon 20 tends to escape to the outside environment through the center hole of both the sealing film tube 11 and the air filling pipe 10. As seen in
After the balloon has been inflated to a predetermined size, a lighting device 30 may be added to the device 70. The lighting device 30 is preferably inserted into the balloon through the tube assembly 50 to provide lighting to the balloon assembly 80. Also, if desired, the lighting device 30 may be inserted prior to inflation. The lighting device 30 includes an extension rod 38 and a lighting element 31. Referring to
The lighting device 30 inside the balloon transforms a traditional balloon into an attractive, illuminated object. Children carrying the balloon will attract the attention of others, especially at night.
The balloon inflation and air containment device 70 can be provided with a variety of different mounting devices so that the complete, inflated balloon assembly 80 can be mounted in different places.
While the preferred embodiments of the invention have been described in detail, the invention is not limited to the specific embodiments described above, which should be considered as merely exemplary. Further modifications and extensions of the present invention may be developed, and all such modifications are deemed to be within the scope of the present invention as defined by the appended claims.
