Method for producing wet tissue package

Abstract

A method for producing a wet tissue package by which a storage portion for wet tissues which have been used can be easily produced, and wet tissues stored in a package main body can be prevented from drying. A method for producing a wet tissue package provided with a package main body having an opening portion, a lid member to cover the opening portion, and a used wet tissue storage portion, wherein the method is provided with an opening portion formation step, an attachment step for attaching the lid member and an adhesive material, a folding back step for wrapping a plurality of wet tissues, a first sealing portion formation step for forming a first sealing portion and a first sealing extension portion, and a second sealing portion formation step for forming a second sealing portion and also forming the used wet tissue storage portion by joining the second sealing portion and the first sealing extension portion by the adhesive material.

1 . A method for producing a wet tissue including: a package main body in which a plurality of wet tissues is accommodated, an opening portion that is formed on the package main body, a lid member that is attached to an outer surface of the package main body to cover the opening portion, and a used wet tissue storage portion that is capable of storing a used wet tissue therein,
 the method comprising steps of:   forming the opening portion on a strip-shaped sheet member;   attaching the lid member to the sheet member in a manner so that the opening portion is covered from a top surface side or a bottom surface side of the sheet member, and attaching an adhesive material to an upstream side and/or a downstream side of a position to which the lid member is attached;   disposing the plurality of wet tissues on a surface of the strip-shaped sheet member at a side to which the lid member and the adhesive material are not attached;   folding back each of a pair of side edges along a direction of flow of the sheet member with the plurality of wet tissues being disposed, to a side where the plurality of wet tissues is disposed so as to wrap around the plurality of wet tissues;   forming a first seal portion that extends in the direction of flow of the sheet member and a first seal extending portion that extends from the first seal portion to a direction crossing a direction in which the pair of side edges extends by bonding the pair of side edges of the folded sheet member with each other; and   forming a pair of second seal portions by bonding an upstream side and a downstream side of a position where the plurality of wet tissues is disposed on the sheet member following the step of forming the first seal portion in such a manner as to extend in a width direction of the sheet member, and forming the used wet tissue storage portion by bonding the second seal portions with the first seal extending portion by means of the adhesive material.   
     
     
         2 . The method for producing the wet tissue package according to  claim 1 , wherein
 in the step of forming the first seal portion, the first seal portion is formed at a position off a center in the width direction of the sheet member.   
     
     
         3 . The method for producing the wet tissue package according to  claim 1 , wherein
 in the step of attaching the lid member, a hot melt adhesive agent is used as the adhesive material.   
     
     
         4 . The method for producing the wet tissue package according to  claim 1 , wherein
 an adhesive tape is used as the adhesive material in the step of attaching the lid member, the adhesive tape including a thermoplastic sheet material, and a tackiness agent that is applied to the surface of the sheet material, with which the sheet member is in contact.
