Spreadable adhesive compositions and applicators for use therewith
First Claim
1. An applicator for dispensing a viscous adhesive composition onto a substrate, said applicator having a body with a closed head, a sealable dispensing aperture penetrating the head, conduit or delivery means to supply the adhesive composition to the dispensin aperture, a wide non-porous spreading surface on the exterior of the head around the dispensing aperture, and means for inibiting flow of adhesive compositions along the exterior of the applicator, said means for inhibiting flow of adhesive compositions comprising an annular step positioned between the head of the applicator and that part of the applicator to which a cap is attachable.

Abstract
A spreadable adhesive composition and an applicator (1) for dispensing a spreadable viscous adhesive composition onto a substrate. The spreadable adhesive composition is a spreadable non-flowable cyanoacrylate adhesive composition which contains an odour masking ingredient compatible with the composition. The composition is intended to be spread by the applicator (1). The applicator (1) for spreading the composition includes a closed head (5) with a sealable dispensing aperture (9) penetrating the head (5). A spreading surface (19) is located on the exterior of the head (5) around the dispensing aperture (9) and is used to spread the adhesive onto the substrate. A conduit or delivery means (7) is also provided to supply the adhesive composition to the dispensing aperture (9). The applicator (1) can also include a cap (2) which fits over and covers the head (5). The cap (2) includes a structure (14) which engages with the dispensing aperture (9) to seal the aperture (9) closed preventing adhesive from being dispensed. The invention also provides a container (17) for holding a spreadable adhesive composition. The invention further provides a pack comprising an applicator (1) and a container (17) as described above which a user can assemble to dispense the spreadable adhesive compositions.
