Abstract
Abstract The present invention relates to a re-sealable dispenser-container and a process for producing the container. 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.

455 words
In a package, in combination with wet tissues and dry tissues, a resealable dispenser-container, comprising: a flexible container body capable of being reduced in volume in normal operation and made of a liquid and gas impervious material and having two outer, flexible, substantially rectangular faces; an inner, flexible, liquid and gas impervious sheet between said outer faces for dividing said container body into two separate, closed chambers fluidly isolated from each other, one chamber containing said wet tissues and the other chamber containing said dry tissues; a first one of said faces having a first elongated opening formed centrally therein and extending in the lengthwise direction of said first face; a first flap having dimensions greater than said first opening and having one end fixedly attached to said first face at a position adjacent to and spaced from said first opening so as to define a first container body facing surface and a first outwardly facing surface thereof, said first flap having a first tab positioned opposite said one end thereof; a first pressure sensitive adhesive material on said first container body facing surface; a first non-adhesive member made of a fluid impervious sheet-like material having dimensions less than said first container body facing surface and at least equal to the dimensions of said first opening and secured to said first container body facing surface by said first adhesive material at a position which seals said first opening when said first container body facing surface of said first flap is adhered by said first adhesive material to said first face; and a second one of said faces having a second elongated opening formed centrally therein and extending in the lengthwise direction of said second face; a second flap having dimensions greater than said second opening and having one end fixedly attached to said second face at a position adjacent to and spaced from said second opening so as to define a second container body facing surface and a second outwardly facing surface thereof, said second flap having a second tab positioned opposite said one end thereof; a second pressure sensitive adhesive material on said second container body facing surface; and a second non-adhesive member made of a fluid impervious sheet-like material having dimensions less than said second container body facing surface and at least equal to the dimensions of said second opening and secured to said second container body facing surface by said second adhesive material at a position which seals said second opening when said second container body facing surface of said second flap is adhered by said second adhesive material to said second face; and whereby the wet tissues can be used for washing, followed by a drying operation with said dry tissues.

455 words
In a package, in combination with wet tissues and dry tissues, a resealable dispenser-container, comprising: a flexible container body capable of being reduced in volume in normal operation and made of a liquid and gas impervious material and having two outer, flexible, substantially rectangular faces; an inner, flexible, liquid and gas impervious sheet between said outer faces for dividing said container body into two separate, closed chambers fluidly isolated from each other, one chamber containing said wet tissues and the other chamber containing said dry tissues; a first one of said faces having a first elongated opening formed centrally therein and extending in the lengthwise direction of said first face; a first flap having dimensions greater than said first opening and having one end fixedly attached to said first face at a position adjacent to and spaced from said first opening so as to define a first container body facing surface and a first outwardly facing surface thereof, said first flap having a first tab positioned opposite said one end thereof; a first pressure sensitive adhesive material on said first container body facing surface; a first non-adhesive member made of a fluid impervious sheet-like material having dimensions less than said first container body facing surface and at least equal to the dimensions of said first opening and secured to said first container body facing surface by said first adhesive material at a position which seals said first opening when said first container body facing surface of said first flap is adhered by said first adhesive material to said first face; and a second one of said faces having a second elongated opening formed centrally therein and extending in the lengthwise direction of said second face; a second flap having dimensions greater than said second opening and having one end fixedly attached to said second face at a position adjacent to and spaced from said second opening so as to define a second container body facing surface and a second outwardly facing surface thereof, said second flap having a second tab positioned opposite said one end thereof; a second pressure sensitive adhesive material on said second container body facing surface; and a second non-adhesive member made of a fluid impervious sheet-like material having dimensions less than said second container body facing surface and at least equal to the dimensions of said second opening and secured to said second container body facing surface by said second adhesive material at a position which seals said second opening when said second container body facing surface of said second flap is adhered by said second adhesive material to said second face; and whereby the wet tissues can be used for washing, followed by a drying operation with said dry tissues.
