  • Patent number: 9242826
    Abstract: This method for producing wet wipes includes the following steps: a step for vertically folding non-woven cloth sheets; a step for impregnating the sheets with a chemical; a step for stacking the sheets; a step for cutting the sheets at predetermined lengths; a step for pulling the cut sheets away from a transporting conveyer provided with a suction mechanism by means of a pusher, and stacking the cut sheets; a step for pressing a bundle comprising the sheets; and a step for packaging the bundle. The pusher is disposed between the transporting conveyers. The blades of the pusher have a plurality of tooth sections. The pusher drops the sheets suctioned to the transporting conveyer downwards by means of moving vertically downwards.

  • Patent number: 9232876
    Abstract: In order to achieve both ease of removal and an increase in the rate of impregnation by a predetermined chemical, in this packaging structure of a package of wet wipes, a convex region is formed at a position containing a region that faces the opening of a main package body and that is on the upper surface of a stacked body of wet wipes. The convex region is formed protruding towards the main package body. A space is formed between the region (corresponding to the ends) aside from the convex region formed on the wet wipes and the upper surface to which the opening of the main package body is provided.

  • Patent number: 8960439
    Abstract: A wet tissue package that is easily to manufacture with a used wet tissue storage receptacle disposed on a package body. Configured is a wet tissue package equipped with a package body and a used wet tissue storage receptacle, wherein the package body is equipped with a first seal portion formed by joining a pair of first side edges of a sheet member, and a pair of second seal portions formed by joining a pair of second side edges, and a wet tissue housing. The used wet tissue storage receptacle is composed of a first seal extension portion formed by extending in a direction that intersects a direction that the first side edges extend from the first seal, and a sheet member that composes the package body.

  • Patent number: 8657152
    Abstract: To provide a wet tissue package that allows for easy taking out of a wet tissue accommodated in a package body. A wet tissue package includes: a package body having an opening; and a plurality of wet tissues accommodated in the package body in a state of being individually folded and stacked without being interfolded, in which each of the plurality of wet tissues includes: a first folding line parallel to the first side edge; a second folding line parallel to the first folding line; and a turn-back portion formed by folding the wet tissue on the first folding line and the second folding line, in which the turn-back portion is directed toward the opening and a part of the turn-back portion is disposed so as to be exposable through the opening.

  • Publication number: 20130267401
    Abstract: The present invention prevents unevenness in the amount of impregnation by a predetermined chemical and prevents a decrease in ease of removal resulting from increasing the rate of impregnation by the predetermined chemical. A press device (15) has: a plurality of rollers (201, 202, 203); press belts (204a, 204b) wound around the plurality of rollers (201, 202, 203); and conveyor belts (205, 206) that convey a stacked body (800). At least one roller from among the plurality of rollers (201, 202, 203) drives the press belts (204a, 204b) at a predetermined speed of conveyance and in a predetermined direction of conveyance. The press belts (204a, 204b) are disposed with a gap in an intersecting direction (CD) perpendicular to the conveyance direction (MD) that is such that the press belts (204a, 204b) can contact both end portions (800A, 800B) of the stacked body (800) in the intersecting direction (CD).
