Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
In combination: a fever thermometer and a protector therefor, the protector consisting of an expansible plastic film detachably bonded to a backing material having low expansibility and elasticity, the backing material being paper with an area weight of 20-50 g/m 2 and defining tear indications, holes or perforations disposed for penetration by the point of the thermometer, and said plastic film having an expansibility of at least 700% and a thickness of between 0.005-0.1 mm, and the material of said plastic film being essentially non-elastic linear low density polyethylene having a breaking strength of at least 32 MPa and a yield point of below 15 MPa, whereby said film, when the point of the thermometer is pushed thereagainst, is stretched and extended over its yield point so that the film clings to the thermometer while the low expansibility and elasticity of the backing material permits the backing material to be penetrated by the pushed thermometer point and, when the backing material is detached from the film clinging to the thermometer and the film is removed from the thermometer, the film is pulled towards the point of the thermometer at the same time as it is automatically turned inside-out.

Dependent Claim

Claim 3
Dependent Claim
17 words
The combination protector according to claim 9, wherein the plastic film glued or welded to the paper.
Claim 4
Independent Claim
156 words
A method of protecting a fever theremometer, which comprises the step of applying thereto a protector consisting of an expansible plastic film detachably bonded to a backing material having low expansibility and elasticity, said plastic film having an expansibility of at least 700% and a thickness of between 0.005-0.1 mm, and the material of said plastic film being essentially non-elastic linear low density polyethylene having a breaking strength of at least 32 MPa and a yield point of below 15 MPa, and the protector being applied to the thermometer by pushing the point thereof against the film whose expansibility and breaking strength causes the film to be stretched and extended over its yield point so that the film clings to the thermometer while the low expansability and elasticity of the backing material permits the backing material to be penetrated by the pushed thermometer point, and detaching the backing material from the film clinging to the thermometer.
