Abstract: Means are provided in an absorbent product, such as a catamenial tampon, for greatly reducing the tendency for fibrous particles to break loose from the body of the product during use, this condition being referred to as "sloughing". The means comprise a pad of absorbent material having printed on at least one surface thereof a non-occlusive pattern of adhesive binder. The pad, when used for a catamenial tampon, is turned upon itself into a generally cylindrical shape which may be compressed into the final tampon.
Abstract: A sanitary napkin having an adhesive element thereon for attaching to a undergarment is provided with means for both protecting the napkin and the adhesive element prior to use and for disposing of the napkin after use. The means comprise providing the napkin with a wrapper sheet of flexible material overlying one major surface, and the sides of the napkin and at least partially overlapping on the second major surface of the napkin. The sheet is releasably adhered to and held in place by the adhesive element.

Abstract: An absorbent body is provided for use in such products as catamenial napkins and tampons, diapers, wound dressings and the like, which body incorporates hydrophilic, wet resilient, swellable, cellulosic fibers produced by a single reaction treatment of cellulose. The cellulose fibers are treated with an agent which renders the fibers hydrophilic while simultaneously crosslinking them with a crosslinking radical having the structure: ##EQU1## where X is chosen from the group consisting of H or COOY: Y is chosen from the group consisting of Na, K, Li, Ce or H; and k, m and n are integers ranging from 0 to 4.
Abstract: A package is provided for containing a clinical thermometer together with a plurality of disposable thermometer sheaths while insuring that these components will be free from dirt and breakage. The package comprises an envelope having both a closed and an open transverse end and being folded about the fold line essentially equidistant between the transverse ends. A pocket is provided in the wall of a first section within the folded envelope and a plurality of thermometer sheaths may be affixed to a second inside wall.
Abstract: A package is provided especially for containing sterile articles which can be readily opened and which provides for the controlled removal of the contents. The package is sealed in a manner which precludes the formation of channels leading to the interior of the package and compromises sterility. Specifically, the end seal of the package is provided by providing a thermoplastic adhesive which acts as a caulk to seal such potential channels, the thermoplastic adhesive being disposed in a manner whereby it is assured that said adhesive does not contact adhesively incompatible areas.
Abstract: A biodegradable barrier film is provided which is useful as a barrier layer in absorbent pads such as sanitary napkins and diapers. The film comprises a matrix of a non-biodegradable film-forming material which is resistant to solubility in water having a biodegradable material homogeneously dispersed therein, the biodegradable material being present in said film in an amount from about 40 to about 60 weight percent based on the total weight of said biodegradable and said non-biodegradable film-forming material in said film.
