Wiping article

Abstract

A wiping article that has excellent portability and, when necessary, that can be set to a wet state for use. The wiping article is formed by compressing a sheet material, which has a shape and size that can be used for hand wiping etc., into a small size and receiving it in a pack. The pack ( 11 ) has a flat structure, and the inside of the pack is partitioned into at least two chambers ( 12, 13 ) by a partition belt. The partition belt can seal liquid ( 17 ) in and has strength and structure that lead to breakage of the belt under pressure exceeding a predetermined level. The sheet material ( 10 ) is compressed and formed into a shape and size that can be used for hand wiping etc. when the liquid is impregnated into the material to swell and expand it. The sheet material is placed in one ( 12 ) of the two chambers of the pack, and the liquid that is impregnated into the sheet material to swell it when the partition belt is broken is placed in the other chamber ( 13 ).

1 . A wiping article having a sheet material of a shape and a size which allow usage as a hand towel or the like compactly compressed and stored in a pack, wherein the pack having a flat structure and an interior divided into at least two chambers by a separating band is used, the separating band has a hermeticity against liquid and has a strength and a structure which is broken to connect the two chambers when a pressure higher than a predetermined level is applied, the sheet material which is compression-molded so as to expand when being impregnated with liquid and assume a shape and a size usable as a hand towel or the like when being spread is used, the sheet material is arranged in one of the two chambers of the pack, and the liquid which causes the sheet material to expand by being impregnated therewith upon breakage of the separating band is arranged in the other one of the two chambers of the pack. 
   
   
       2 . The wiping article according to  claim 1 , wherein the pack is formed by using thermoplastic resin films and bonding strongly along the periphery thereof, and the interior thereof is divided into two chambers by weakly bonding the separating band which divides the pack into two chambers to a midsection, and thermoplastic resin of a different type or the same type which is bonded at a weaker bonding force than the bonding between the thermoplastic resins used in the pack is interposed between the thermoplastic resin films which constitute the pack in order to provide a weakly bonded separating band. 
   
   
       3 . A wiping article having a sheet material having a shape and a size which allow usage as a hand towel or the like and being compactly compressed and stored in a pack, wherein the pack for storing the sheet material includes a pack structure which is hard to be broken by using thermoplastic resin films and forming a strongly bonded portion along the peripheral edge of the pack and a breaking force inducing portion extending inward from the strongly bonded portion on the peripheral edge of the pack, and wherein the interior of the pack is separated into two chambers by providing a separating band which is broken relatively easily provided on the breaking force inducing portion or between the breaking force inducing portion and the peripheral edge of the pack by forming a weakly bonded portion which is weaker than the strongly bonded portion, one of the chambers in which the breaking force inducing portion is provided is filled with liquid for expanding the sheet material by causing the same to be impregnated therewith by the breakage of the separating band, and the other chamber includes the compressed sheet material which expands when being impregnated with the liquid and assumes a shape and a size which allow usage as a hand towel or the like arranged therein. 
   
   
       4 . The wiping article according to  claim 3 , wherein the breaking force inducing portion extends inward from the strongly bonded portion of the peripheral edge of the pack toward the separating band and has an inclined portion inclining toward an easy-breaking portion. 
   
   
       5 . The wiping article according to  claim 3 , wherein the breaking force inducing portion includes a structure substantially symmetric having the easy-breaking portion positioned at a center and the inclined portions on the left and right thereof. 
   
   
       6 . The wiping article according to  claim 1 , wherein heating means for heating the sheet material expanded by being impregnated with the liquid is provided in the pack in parallel for enabling the sheet material to be warmed up for use. 
   
   
       7 . The wiping article according to  claim 1 , wherein cooling means for cooling the sheet material expanded by being impregnated with the liquid is provided in the pack in parallel for enabling the sheet material to be cooled down for use.
