    摘要: A resealable pack having a body portion formed substantially of flexible sheet material and defining an article-receiving cavity. The body portion comprises a first end defined by an end wall and tapers to a second end spaced apart from the first end. The body portion also comprises a face in which is defined a dispensing opening. A resealable sealing member is secured to the body portion and, in a closed position, covers the opening in sealing contact with the body portion around the periphery of the opening. A plurality of sheet-form articles is disposed within the cavity in the form of a flattened roll, with one end of the roll being capable of extending through the opening.

    摘要: A synthesis is described for the preparation of cationic polymer materials with a semisynthetic matrix, having superabsorption characteristics towards water and saline solutions. More particularly, cellulose cationic derivatives are described, having superabsorption characteristics, which are obtained starting from cellulose substrates which are reacted with an excess of quaternary ammonium compound in an alkaline medium.

    摘要: A fibrous composition for absorbent pads which, in addition to cellulose fibers, also contains first and second synthetic polymeric materials. At least the second polymeric material is constituted by synthetic fibers which have a higher melting point than that of the first polymeric material. The fibrous mixture is formed into the desired shape, for example, an absorbent body for disposable sanitary products, by pneumatic means. The absorbent body thus formed is then heat-treated to a temperature higher than the melting point of the first polymeric material but lower than that of the second polymeric material for a period of time so as to melt the first polymeric material and form bonding points or bridges between at least the synthetic fibers which have not melted and which constitute the second polymeric material. The absorbent body is cooled to a temperature such that the first polymeric material sets, bonding at least the synthetic fibers together so as to form a framework containing the cellulose fibers.

    摘要: Disclosed is a thin, layered, absorbent structure comprising first and second layers of fibrous material and an intermediate layer comprising particles of a hydrogelling, absorbent material, in an amount exceeding 120 g/m.sup.2, and particles of a thermoplastic, polymeric, organic material; the first and second fibrous layers extend beyond the intermediate layer laterally to form longitudinal edge portions. The two fibrous layers are bound together with the intermediate layer between them by the melting of the particles of thermoplastic, polymeric, organic material and by means of a continuous line of adhesive extending longitudinally on each longitudinal edge portion.
