Abstract

Abstract A body warming bladder of pliable, waterproof material has a central portion and at least two separate limbs. The bladder has an opening for filling it with heated liquid, and a releasable end cap for normally sealing the opening. In one version of the invention the bladder is shaped to correspond substantially to the shape of a child's plush toy and is mounted inside the body of the toy with a portion of the bladder extending up to a suitable access opening in the body which registers with the bladder opening to allow the bladder to be filled with warm water. In another version the bladder is of generally V- or boomerang like shape with the access opening at the center of the V-shape, and can be fitted inside a slipper to warm the wearer's feet or used to warm other body parts.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 144 words
A body warming bladder device for fitting over a foot inside a slipper or other footwear, comprising: a hollow bladder of pliable, waterproof material comprising upper and lower layers having peripheral edges of matching shape, the layers being joined together around their peripheral edges to define a cavity and the bladder being of V-shape having a central, apex portion and two separate limbs extending from the central portion and diverging away from one another to form the V-shape with the limbs being unconnected and separate from one another along their length between the apex of the V-shape and the outermost free ends of the limbs; the bladder having an inlet/outlet opening in one of said layers spaced from said peripheral edges for filling the bladder with warm liquid and subsequently emptying the bladder; and releasable end cap means for releasably sealing the inlet/outlet opening.
Claim 2
Dependent Claim 144 words
A body warming bladder device for fitting over a foot inside a slipper or other footwear, comprising: a hollow bladder of pliable, waterproof material comprising upper and lower layers having peripheral edges of matching shape, the layers being joined together around their peripheral edges to define a cavity and the bladder being of V-shape having a central, apex portion and two separate limbs extending from the central portion and diverging away from one another to form the V-shape with the limbs being unconnected and separate from one another along their length between the apex of the V-shape and the outermost free ends of the limbs; the bladder having an inlet/outlet opening in one of said layers spaced from said peripheral edges for filling the bladder with warm liquid and subsequently emptying the bladder; and releasable end cap means for releasably sealing the inlet/outlet opening.
Claim 3
Dependent Claim 33 words
