A process for producing a re-sealable dispenser-container is provided. The dispenser-container comprises a main container body made of impervious material with at least one opening, a flap having a pressure-sensitive adhesive surface and fixed to the main body at one end thereof to cover the opening, and a non-adhesive member adhered to the adhesive surface and which member is used for closing the opening in order to prevent the adhesive surface from directly contacting the contents. The process comprises punching a perforated line in a sheet used for the main body, disposing a flap on the sheet so as to cover the perforated line, fixing one end of the flap to the sheet, and sealing the sheet longitudinally and transversely.

A continuous process for producing from a continuous flexible sheet a re-sealable dispenser container formed in a rectangular shape and having at least one opening, and being wrapped around a plurality of solid sheet-like materials for cosmetic or toilet use contained therein, comprising the steps of: continuously feeding said continuous flexible sheet of impervious material in a substantially horizontal plane; periodically weakening a line drawn in a closed elongated shape at a central portion in said continuous flexible sheet; periodically disposing a flexible flap from above, the flap having an adhesive surface covering substantially one entire side of the flap, the flap also having an uncoated tab, on the upper surface of said continuous sheet in such a manner that the flap contacts the upper surface of said sheet and covers said weakening line, adhering the adhesive surface of said flap to the surface of said elongated shape; periodically fixing one end portion of said flap to said continuous sheet; guiding said continuous sheet by means of a guide unit comprising a plurality of guide rollers to invert said continuous sheet such that the lower surface becomes the new upper surface; continuously moving said continuous sheet in a substantially horizontal plane; periodically disposing said sheet-like materials for cosmetic or toilet use on the new upper surface of said continuous sheet at a position corresponding to said flap when the continuous sheet is moved in said substantially horizontal plane; said weakening, flap disposing and fixing steps being continuously performed on said continuously running sheet; continuously wrapping said continuous sheet around said sheet-like materials for cosmetic or toilet use with the continuous sheet so folded that longitudinal edges of said continuous sheet are brought together upon each other at the central portion of said continuous sheet; continuously heat sealing the longitudinal edges of the continuous sheet to each other to form a continuous longitudinal heat seal and heat sealing said sheet transversely to form a succession of transversely sealed portions; and periodically cutting said continuous sheet at said transversely sealed portions to provide a plurality of separate re-sealable dispenser containers.
