1,146,293. Tampons. KIMBERLY-CLARK CORP. 21 March, 1966 [31 March, 1965], No. 12391/66. Heading A5R. A catamenial tampon comprises a folded rectangular strip of compressed absorbent material which is capable of expanding when wetted and which, when folded and unrestrained, tends to spring back to its unfolded condition, the tampon having been formed by folding the strip of compressed material transversely on itself to a size suitable for insertion into the vaginal cavity. The strip 12 may have one, two or three folds to give a tampon of two, three or four layers. The strip may be held temporarily in folded configuration by a sleeve (25, Fig. 3b,) not shown of water-soluble film, e.g. polyvinyl alcohol, methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose or sodium cellulose sulphate, or by a conventional applicator tube, or by the withdrawal string 14 attached to one free end of the strip co-operating with a longitudinal slot 19 cut through a juxtaposed portion of the folded strip. The absorbent material may be natural sponge, cellulose or regenerated cellulose sponge or sponge material comprising vinyl alcohol or vinyl chloride and copolymers thereof. Alternatively, the absorbent material may comprise a combination of absorbent and non-absorbent synthetic fibres and absorbent natural fibres.
