Abstract
Abstract A rapidly opening sealed package for wound dressing adhesive tape comprising an adhesive support carrying a wound dressing pad covered endwise by a pair of protective films attached to a pair of outer sheaths so that by pulling the outer sheaths apart the protective films will move therewith to separate centrally and uncover the wound dressing pad. An adhesive layer is applied adjacent said wound dressing pad between said protective films and said outer sheaths. In this manner a material of poor adhesive power such as siliconated paper may be used for the protective films.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
232 words
A rapidly opening sealed package for wound dressing adhesive tape, comprising an adhesive support having a non-adhesive wound dressing area carrying a wound dressing pad, a pair of protective films attached to said adhesive support, and an outer wrapper formed substantially of a pair of flat tubular outer sheaths closed at their peripheral edges and having adjacent ends adhesively sealingly connected to one another but separable by pulling them apart, characterized in that said pair of protective films have a small degree of adhesion only at their inner surfaces attached to said adhesive support and each of them is adhesively connected to a separable portion of said wrapper by means of an adhesive layer provided between a portion of an outer surface of each protective film and a corresponding adjacent portion of an inner surface of said wrapper in an area in the vicinity of said wound dressing pad, the overall assembly being of a generally flat configuration and such that when pulling apart said tubular sheaths of said wrapper said protective sheaths will remain adherent in the portion thereof adhesively connected to the corresponding separated portions of said wrapper and will be folded back upon themselves in opposed S and Z shapes and will be detached from said wound dressing pad by sliding within said wrapper formed of said pair of tubular sheaths, exposing said wound dressing pad ready for application.
