Abstract

A composition applicator tip adapted to deliver a “rippled” bead of composition to a surface of a substrate, the composition applicator tip including: a hollow conduit structure defining a pair of opposed openings and adapted to deliver the composition there through, wherein a first opening of the pair of opposed openings is adapted to be coupled to a composition delivery vessel; and an end wall enclosing a second opening of the pair of opposed openings, wherein the end wall defines an elongate slot that is adapted to be disposed substantially parallel to the surface of the substrate in use and expel the composition there through, and wherein a portion of the end wall disposed beneath the elongate slot has a height such that the composition falls by gravity a predetermined distance to the surface of the substrate in use as the composition applicator tip is translated along the surface of the substrate.

First claim

What is claimed is:

1 . A composition applicator tip adapted to deliver a “rippled” bead of composition to a surface of a substrate, the composition applicator tip comprising:
a hollow conduit structure defining a pair of opposed openings and adapted to deliver the composition there through, wherein a first opening of the pair of opposed openings is adapted to be coupled to a composition delivery vessel; and
an end wall enclosing a second opening of the pair of opposed openings, wherein the end wall defines an elongate slot that is adapted to be disposed substantially parallel to the surface of the substrate in use and expel the composition there through, wherein the end wall defines a concave-outwards central dome structure disposed about the elongate slot that partially defines the elongate slot, and wherein a portion of the end wall disposed beneath the elongate slot has a height such that the composition falls by gravity a predetermined distance to the surface of the substrate in use as the composition applicator tip is translated along the surface of the substrate.

2 . The composition applicator tip of claim 1 , wherein a lower portion of the hollow conduit structure defines a ramp structure that is adapted to contact the surface of the substrate in use and allows the composition applicator tip to be disposed at one or more predetermined angles with respect to the surface of the substrate.

3 . The composition applicator tip of claim 1 , wherein a lower portion of the hollow conduit structure defines a fin structure that is adapted to contact the surface of the substrate along a seam in use and allows the composition applicator tip to be oriented with respect to the surface of the substrate as the composition applicator tip is translated along the surface of the substrate.

4 . The composition applicator tip of claim 1 , wherein an upper portion of the hollow conduit structure defines a fin structure.

5 . The composition applicator tip of claim 1 , wherein the first opening of the pair of opposed openings of the hollow conduit structure is adapted to be coupled to one or more of an adapter and a static mixer adapted to be coupled to the composition delivery vessel.

6 . The composition applicator tip of claim 1 , wherein the hollow conduit structure comprises one or more internal protruding structures that are adapted to statically mix the composition as the composition is delivered through the hollow conduit structure.

7 . The composition applicator tip of claim 1 , wherein the elongate slot has a width substantially parallel to the surface of the substrate of between 5 mm and 50 mm.

8 . The composition applicator tip of claim 7 , wherein the thickness of the elongate slot does not vary along the width of the elongate slot.

9 . The composition applicator tip of claim 1 , wherein the elongate slot has a thickness substantially perpendicular to the surface of the substrate between 0.1 mm and 5 mm.

10 . The composition applicator tip of claim 1 , wherein the elongate slot comprises a rectangular slot.

11 . The composition applicator tip of claim 1 , further comprising a retention flange that is adapted to engage the composition delivery vessel.

12 . The composition applicator tip of claim 1 , wherein the hollow conduit structure has a substantially-cylindrical structure.

13 . A composition delivery vessel adapted to deliver a “rippled” bead of composition to a surface of a substrate, the composition delivery vessel comprising:
one or more composition storage vessels adapted to collectively contain the composition; and
a composition applicator tip coupled to the one or more composition storage vessels, the composition applicator tip comprising the composition applicator tip of claim 1 .

14 . A composition application method for delivering a “rippled” bead of composition to a surface of a substrate, the composition application method comprising:
providing a composition delivery vessel comprising one or more composition storage vessels adapted to collectively contain the composition and a composition applicator tip coupled to the one or more composition storage vessels, the composition applicator tip comprising the composition applicator tip of claim 1 ; and
expelling the composition from the hollow conduit structure and the elongate slot while holding the composition applicator tip at a predetermined angle and translating the composition applicator tip linearly or curvilinearly along the surface of the substrate.
