ABSTRACT:
An applicator of resilient plastic material having a double wall construction, an air chamber between the walls and spacers in the air chamber is disclosed. The applicator is adapted to be pressed between the thumb and forefinger to dispense glue. The applicator has an applicator body comprising a shoulder, a dispensing opening in the shoulder and a downwardly depending skirt. A cup which is adapted to hold glue, particularly cyanoacrylate glue, is within the skirt and the top and bottom portions of the cup are in fluid tight engagement with the applicator body adjacent the top and bottom of the skirt. The cup fits within the skirt with its walls in spaced apart relationship with the skirt to provide an air chamber therebetween. The shape of cup walls and the opposed skirt generally conform to each other. A preferred embodiment includes friction elements on the outside of the skirt overlying at least a portion of the area covered by the spacers.
