Abstract

The balloon comprises at least two balloon sheets ( 1 ) sealed to one another along a peripheral edge ( 2 ) to form an inflatable body ( 4 ) and an inflatable stem ( 5 ) connected by its proximal end to the body. In order to be able to hold the balloon the stem comprises a handle portion ( 17 ) which has, in an uninflated flat state of the balloon, an inner width (w) comprised between 30 and 80 mm and a length of at least 80 mm. The stem ( 5 ) further comprises a proximal portion ( 18 ) which widens in such a manner towards the body ( 4 ) that, when holding the balloon in its inflated state upright by the handle portion ( 17 ), the body ( 4 ) of the balloon returns to one single stable position after having bent the balloon in a transverse direction. Since the balloon can be held by the inflated handle portion, no cups or sticks have to be attached to the balloon.

Claims

exact text as granted — not AI-modified
1 . An inflatable non-latex balloon comprising at least two balloon sheets sealed to one another along a peripheral edge to form an inflatable body and an inflatable stem each having an interior, the inflatable stem being in fluid communication with the body and having a proximal end by means of which it is connected to the body, characterised in that the stem comprises a handle portion and a proximal portion, the handle portion showing a longitudinal axis and having, in an uninflated flat state of the balloon, an inner width comprised between 30 and 80 mm and a length of at least 80 mm, and the proximal portion of the stem widening in such a manner towards the body that, when holding the balloon in its inflated state by the handle portion so that said longitudinal axis of the stem extends in a vertical direction, the body of the balloon returns to one single stable position after having bent the balloon in a transverse direction perpendicular to the direction of said longitudinal axis.  
     
     
         2 . A balloon according to  claim 1 , characterised in that said proximal portion of the stem overlaps said handle portion at least partially.  
     
     
         3 . A balloon according to  claim 1 , characterised in that, in the uninflated flat state of the balloon, the interior of the proximal portion of the stem has two side edges each defining a side edge curve which is situated over at least a part of the proximal portion between two curves which are defined in an orthogonal axe system having an X axis coinciding with said longitudinal axis and an Y axis perpendicular thereto by the formulae:
