ABSTRACT:
A method is provided for manufacturing liquid dispensers of the general type having a body 10 presenting a pocket 16, a glass ampule 12 received in the body and enclosing a liquid to be dispensed, and a porous element 14 covering the pocket of the body. The method includes arranging a plurality of bodies 10 in a row, bottom ends up, on a tray, and placing ampules 12 in the pockets 16. A strip 72 of porous material is aligned over the pockets of the bodies and secured in place. Thereafter, the strip is cross cut into individual elements to complete the manufacture of the liquid dispensers. The securing step is preferably carried out by ultrasonically welding the porous material to the bodies so that it is not necessary to use adhesives. The cross-cutting step is preferably carried out by pressing a heated wire through the strip of porous material at a position intermediate each pair of adjacent bodies. An apparatus for carrying out manufacture of the dispensers is also provided.
