Abstract

A perspiration shield (101) comprises reinforcing layer (203), perspiration impermeable layer (204), perspiration absorbent layer (205) and liner layer (206). The perspiration impermeable layer (204) is provided with an adhesive composition (215) disposed on a border (214) of its inner face (213), forming an adhesive region (216). The perspiration absorbent layer (205) comprises a perspiration absorbent material which is arranged on the inner face (211) of the perspiration impermeable layer (204). The reinforcing layer (203) and the liner layer (206) are releasably attached to the perspiration impermeable layer (204) and the perspiration absorbent layer (205) respectively. The liner layer (206) and the reinforcing layer (203) are releasable prior to and following respectively adhering of the shield (101) to the skin of a wearer's (102) underarm about the adhesive region (216). The shield (101) obviates issues in relation to skin irritation and poor adhesiveness whilst providing a shield (101) that is more easily applied and is sufficiently stable to be stored prior to use.

Dependent claims

A perspiration shield releasably adherable to the skin of an underarm, the shield having an inner face and an outer face, the shield comprising:

a perspiration impermeable layer having an inner face, an outer face, and a peripheral edge, and comprising a silicone based adhesive suitable for releasably adhering said shield to the skin of an underarm, said adhesive being disposed on said inner face of the perspiration impermeable layer adjacent its peripheral edge and forming an adhesive border;
a perspiration absorbent material arranged on the inner face of said perspiration impermeable layer and within the adhesive border;
and
a liner layer having an inner face, an outer face, and a peripheral edge, said liner layer being arranged such that its outer face is in contact with said inner face of said perspiration impermeable layer and extends substantially fully across said adhesive border thereof so as to substantially cover said adhesive border thereof, said liner layer comprises low-density polyethylene (LDPE) material.
