US 5,729,955 A · Method of manufacturing packet with wet tissues

Abstract

A packet with wet tissues is continuously manufactured. At first, a lid unit part including a pick-up port enabling pop-up of a wet tissue and a lid body capable of sealing the pick-up port is prepared. An air-tight film is continuously supplied, and an opening portion is formed in the film by punching. Then, the lid unit part is placed on the film with the opening portion, and a peripheral portion of a base member of the lid unit part is joined with a peripheral edge portion of the opening portion. Thereafter, a wet tissue stacked body is placed on the film with the lid unit part and is wrapped by the film. Center lap portions of the film are joined to each other while respective end lap portions formed at both end sides are joined to each other to thereby form a packet. A boundary portion between the adjacent two packets is cut for separating the packets from each other.

forming a hole in said film by punching for forming an opening portion;
supplying said lid unit part and placing said lid unit part on said film at a position where said opening portion is formed;
allowing a peripheral portion of a base member of said lid unit part to abut against a peripheral edge portion of said opening portion, and joining mutual abutment portions to each other;
supplying a wet tissue stacked body and placing it on said film at a position where said lid unit part is disposed;
and
wrapping said wet tissue stacked body with said film, joining center lap portions of said film to each other while joining respective end lap portions formed at both end sides in a direction along said center lap portions to each other to form a packet, and cutting a boundary portion between adjacent two packets for separating said packets from each other.
