Methode zur Verringerung der Maschenweite eines Ausgabekopfs zur Ausgabe einer Flüssigkeit

摘要

A method of making a head (50) for a semisolid product dispenser (10) such as a gel deodorant dispenser, comprises the steps of: providing a piece of porous media (60) having a desired shape with a perimeter (68) and openings (66) through the media in the area inside of the perimeter, compressing at least the portion of the media inside of the perimeter between two parts of a heard tool (102,104), thereby reducing the size of the openings, and affixing the porous media to a head from (70) to form the semisolid product dispenser head. A preferred porous media is made of two layers of extruded strands of polymer. Preferably the head of the semisolid product dispenser is made by ultrasonically welding the head frame to the body using a combination of double shear and energy-directing ultrasonic weld joints, coupled with a positive stop.
