Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS :
1. A tamper- or damage- indicating member, which comprises an inner layer and an outer layer, at least a portion of said outer layer being sealed to said inner layer so as to
surround a zone of the -inner layer which is not sealed to the outer layer, both the outer and inner layers being of substantially liquid- and air- impermeable material and the space between said layers in said zone being substantially free of air, said outer layer being translucent or
transparent at least in the area thereof overlying said zone and having a contrasting colour relative to the
colour of said inner layer.

2. A member as claimed in claim 1, wherein said area of said outer layer is substantially lighter in colour than said zone of said inner layer.

3. A member as claimed in claim 1 or 2, wherein said outer layer is thinner than said inner layer.

4. A member as claimed in any of claims 1 to 3, wherein a
release layer is provided between the outer surface of the inner layer and the inner surface of the outer layer.

5. A member as claimed in any of claims 1 to 4, wherein said space includes a chemical which changes colour in the
presence of oxygen, water or other fluids.

6. A member as claimed in any of claims 1 to 5 , which is in the form of a glove, wherein said inner layer comprises a flexible inner glove-shaped body and said outer layer
comprises a flexible outer glove-shaped body surrounding the inner body, the inner and outer bodies being sealed together at or near the wrist-engaging edges thereof, a substantial proportion of the outer surface of the inner body being in contact with the inner surface of the outer body but unbonded thereto and said space being
substantially evacuated.

7. A glove-shaped member having a plurality of layers, which comprises an inner glove-shaped body and an outer
glove-shaped body surrounding the inner body, the outer glove-shaped body being secured to the inner body by the resilience _of the outer body, the inner and outer bodies each being of flexible, substantially liquid- and
air- impermeable material, the outer layer being
translucent or transparent and having a contrasting colour relative to the colour of said inner laye .

8. A member as claimed in claim 6 or 7, wherein said outer body is substantially of transparent or translucent
material, the inner body being relatively more strongly coloured.

9. A member according to any of claims 6 to 8, wherein said inner and outer bodies are each of elastomeric material and/or wherein the space between the inner and outer
bodies contains a dye, and/or an anti-bacterial an
antiviral substance.

10. A method of producing a member according to any of claims 6 to 8, wherein a first one of said bodies is formed by dip- forming an elastomeric latex on a shaped former to
form an uncured glove-shaped body; surface halogenating at least part of the dip-formed elastomeric material present on said former; dip- forming an elastomeric latex onto said halogenated glove-shaped body to form a further uncured glove-shaped body surrounding said halogenated
glove-shaped body; and removing said glove- shaped bodies jointly from said former.
