Container assembly for brush-on adhesive

Container for brush-on adhesive

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.

Double wall applicator

There is disclosed a method for accelerating the cure of cyanoacrylate adhesive by contacting the adhesive with a coating of an accelerator on a tape or sheet. Preferred embodiments relate to bonding a fabric to a substrate by placing a fabric in pressure contact with a substrate, said fabric having cyanoacrylate adhesive on one side thereof and openings of sufficient size between adjacent fibers to permit cyanoacrylate adhesive to pass through to the opposite side of the fabric and then contacting adhesive on the side away from the substrate with a polymerization accelerator coated on a backing. There is also disclosed a backing material such as a tape or sheet having a polymerization accelerator for cyanoacrylate adhesive coated on one side thereof, preferably, wherein the backing material does not bond to the cyanoacrylate on the side carrying the coating. Use of the method and backing material is particularly described for use in the manufacture of serigraphic screens.
