Abstract

Sterile package moist woven cloth towel and method for producing same in hermetically sealed packages. The invention comprises inserting a small woven cotton cloth towel, such as of terry cotton, into a liquid impervious envelope, injecting a sufficient volume of liquid into the envelope to impregnate the towel, hermetically sealing the envelope and finally exposing the envelope to sufficient radiation to cause sterilization of the liquid-impregnated towel therewithin. The woven cloth is capable of laundering for subsequent use in wet or dry condition.

Claims

1. Method for providing moist towelettes which are sterile, durable, suitable for repeated reuse and capable of laundering for subsequent reuse in either moist or dry condition, said method comprising forming an absorbent woven cotton cloth towelette, folding said towelette into a multi-ply reduced size, inserting said folded towelette into package which is capable of being sealed and rendered water-impervious, injecting a sufficient volume of an aqueous composition into said package to impregnate said towelette therewith, sealing said package to render it water-impervious and exposing said sealed package to sufficient radiation to sterilize said impregnated towelette and maintain it sterile for so long as said package remains sealed, said woven cotton fabric towelette being capable of being laundered for subsequent reuse in either moist or dry condition.

2. Method according to claim 1 in which said package has resealable opening means to permit said impregnated towelette to be removed from the package, used and reinserted and resealed to maintain it in moist condition for reuse.

3. Method according to claim 1 in which said woven cotton cloth comprises terry cotton.

4. Method according to claim 1 in which said package comprises a laminate of a heat-fusible plastic film and a metallic foil and said package is sealed by heat and pressure.

5. Method according to claim 1 in which said package is sterilized by exposure to gamma radiation.

6. Method according to claim 1 in which said aqueous composition comprises pure water.

7. A package containing a moist, sterile, durable woven cotton cloth towelette which is impregnated with an aqueous composition, said package being water-impervious and resealable to permit said woven cotton cloth to remain moist for reuse until it becomes excessively soiled, said impregnated woven cotton cloth being sterilized by exposure to radiation while initially sealed within said package, and being launderable for subsequent reuse after it becomes soiled.

8. A package according to claim 7 in which said woven cotton cloth comprises terry cloth.

9. A package according to claim 7 in which said aqueous composition comprises pure water.

10. A package according to claim 7 comprising a laminate of an interior heat-fusible plastic film and a metallic foil, said plastic film being fused to itself to render the package water-impervious.
