Abstract
Abstract A device for sealing an inflated balloon or the like includes a substantially U-shaped member having first and second legs and a connecting portion. The connecting portion functions as a hinge for the two legs. The other or free ends of the legs are adapted to be compressingly closed together. When a balloon neck is inserted between the legs and the legs are thereafter closed together sealing of the balloon is effected. The device further includes a string holder formed on one of the legs, in a first embodiment of the invention.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
In a closure member for sealingly closing an inflated balloon about the neck thereof, the improvement comprising: a freely rotatable first leg; a freely rotatable second leg adapted to be disposed in overlying relationship over the first leg when in closed relationship; the legs being adapted to receive the neck of the object balloon transversely therebetween; flexible hinge means interconnecting the first and second legs, means for clamping the first and second legs together, the means for clamping exerting sufficient compression on the two legs to prevent the passage of fluid therepast, and sealing means provided on the interior surfaces of the legs and which enshrouds the neck of the balloon, the sealing means comprising an elongated channel formed in one of the legs and extending substantially along the length thereof and a projection formed on the other of the legs and extending substantially along the length thereof, the projection being sealingly press fittable into the channel to thereby sealingly close the neck of the inflated balloon.
Claim 2
Dependent Claim
167 words
In a closure member for sealingly closing an inflated balloon about the neck thereof, the improvement comprising: a freely rotatable first leg; a freely rotatable second leg adapted to be disposed in overlying relationship over the first leg when in closed relationship; the legs being adapted to receive the neck of the object balloon transversely therebetween; flexible hinge means interconnecting the first and second legs, means for clamping the first and second legs together, the means for clamping exerting sufficient compression on the two legs to prevent the passage of fluid therepast, and sealing means provided on the interior surfaces of the legs and which enshrouds the neck of the balloon, the sealing means comprising an elongated channel formed in one of the legs and extending substantially along the length thereof and a projection formed on the other of the legs and extending substantially along the length thereof, the projection being sealingly press fittable into the channel to thereby sealingly close the neck of the inflated balloon.
Claim 3
Dependent Claim
18 words
The closure member of claim 1 which further comprises a string holder attached to one of the legs.
Claim 4
Dependent Claim
43 words
The closure member of claim 1 wherein the means for clamping comprises a loop formed on one of the legs and a lip formed on the other leg, the loop being adapted to engage the lip to maintain the legs in clamped relation.
Claim 5
Dependent Claim
45 words
The closure member of claim 1 wherein the means for clamping comprises a projection provided on one of the legs, the other leg having an aperture provided therethrough, the projection being adapted to forcingly pass through the aperture to maintain the legs in clamped relation.
Claim 6
Dependent Claim
49 words
The closure member of claim 1 wherein the means for clamping comprises a locking arm provided on one of the legs, the other of the legs having a slot formed thereon, the slot being adapted to frictionally slidingly retain the locking arm to maintain the legs in clamped relation.
Claim 7
Dependent Claim
27 words
The closure member of claim 1 wherein the hinge means comprises a flexible wall interconnecting the first and second legs, the closure member comprising a unitary member.
Claim 8
Dependent Claim
25 words
The closure member of claim 1 wherein the hinge means comprises a hinge pin extending through registering apertures provided on the first and second legs.
Claim 9
Dependent Claim
162 words
A balloon system comprising: an inflated balloon having a neck, and a closure member transversing the neck of the balloon, the closure member comprising: a freely rotatable first leg; a freely rotatable second leg adapted to be in overlying relationship over the first leg when in closed relationship; flexible hinge means interconnecting the first and second legs; means for clamping the first and second legs together, the means for clamping exerting sufficient compression on the two legs to prevent the passage of fluid therepast, sealing means provided on the interior surfaces of the legs and which enshrouds the neck of the balloon, the sealing means comprising an elongated channel formed on one of the legs, and a projection formed on the other of the legs, the projection being press fittable into the channel to thereby sealingly close the neck of the inflated balloon, and channel forming means disposed on one of the legs for receiving a carrying member for the inflated balloon.
