Definitions

  • the present invention relates to a disposable tissue and a production apparatus thereof, and more particularly, to a disposable tissue compressed into a predetermined shape that can be conveniently carried and hygienically used, and an apparatus for producing the disposable tissue.
  • a disposable tissue is a disposable article that can be scrapped after use in wiping surfaces of various objects or a human skin.
  • the disposable tissue is made of nonwoven, pulp or the like, and is classified into a dry tissue and a wet tissue according to whether moisture is contained therein.
  • the disposable tissue since the disposable tissue has a propensity to suffer damages such as tear or crease, the disposable tissue has been sold in a state where it is packed in a soft sack or a case with a predetermined shape, which can be easily opened. Further, the disposable tissue is packed in a state where it is folded into two or three folds such that it can be easily taken out from the opened sack or case in use. Moreover, it is desirable to pack the disposable tissue in a possible smallest size so that a user can easily store and carry it when the user is on journey or is out.
  • the wet tissue is packed in a sealed container so that moisture contained in the packed wet tissue does not evaporate. Further, the tissue is wetted with water to which antimicrobial is added, and then stored in a cool and dark place to prevent microbes from propagating during the distribution of the wet tissue.
  • the conventional wet tissue should be packed and distributed by the piece so as to prevent the tissue from drying.
  • the conventional wet tissue contains antimicrobial as well as water
  • the wet tissue may cause ill effects on the skin in a case where a child or person with weak skin uses the conventional wet tissue, and the sickening smell of the antimicrobial contained in the wet tissue causes unpleasantness in use.
  • the wet tissue will be stored for a long time, microbes such as colon bacilli are propagated in moisture. Thus, there is a risk of microbial infection.
  • An object of the invention is to provide a novel disposable tissue that can be conveniently stored and carried without packing it by the peace due to its minimum volume obtained through compression molding and can be then used as a wet tissue due to restoration to its origin shape upon supply of water thereto in use.
