Abstract
Abstract The invention concerns a thermotherapeutic packing, in particular for cryotherapy, comprising an impermeably-welded packing casing consisting of a flexible sheet and a heat- or cold-storing liquid and in insert material of spherical bodies comprising aggregates of fibers wound into balls or spheres. The liquid can penetrate these spherical aggregates and accordingly, the packing volume may be less. This packing not only is easily molded, but exhibits gradual heat loss or heat absorption.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
43 words
A pack for thermotherapy comprising a liquid impermeable, welded flexible sheet pack casing containing particles of spherical fiber aggregates of entangled fibers which allow a heat- or cold-storing liquid to penetrate and flow through the fiber aggregates and a heat- or cold-storing liquid.
Claim 2
Dependent Claim
43 words
A pack for thermotherapy comprising a liquid impermeable, welded flexible sheet pack casing containing particles of spherical fiber aggregates of entangled fibers which allow a heat- or cold-storing liquid to penetrate and flow through the fiber aggregates and a heat- or cold-storing liquid.
Claim 3
Dependent Claim
11 words
The pack defined in claim 1, wherein said fibers are synthetic.
Claim 4
Dependent Claim
16 words
The pack defined in claim 1, wherein the spherical aggregates have fiber ends projecting from them.
Claim 5
Dependent Claim
27 words
The pack defined in claim 1, wherein said fibers have a thermal conductivity that is substantially less than the thermal conductivity of the heat- or cold-storing liquid.
Claim 6
Dependent Claim
