Abstract

A sealant-applicator tip comprises a body, having a plane of symmetry and comprising an inlet opening. The sealant-applicator tip also comprises a head, extending from the body opposite the inlet opening. The head comprising a first planar face, comprising a first linear edge, a second planar face, comprising a second linear edge, a third face, comprising a third edge, a fourth face, comprising a fourth edge, a fifth edge, a sixth edge, a seventh edge, and an outlet opening, formed in the third face and in communication with the inlet opening of the body. The sealant-applicator tip further comprises a channel, extending from the inlet opening to the outlet opening.

First claim

What is claimed is:

1. A sealant-applicator tip, comprising:
a body, having a plane of symmetry, wherein the body comprises an inlet opening;
a head, extending from the body opposite the inlet opening, wherein the head comprises:
a first planar face, comprising a first linear edge;
a second planar face, comprising a second linear edge, wherein the first linear edge of the first planar face and the second linear edge of the second planar face lie in a virtual flat plane and are parallel to each other;
a third face, separating the first planar face from the second planar face, wherein the third face comprises a third edge, extending between the first linear edge and the second linear edge, and wherein each of the first planar face and the second planar face is oriented at an oblique angle to the third face;
a fourth face, comprising a fourth edge;
a fifth edge, shared by the first planar face and the fourth face;
a sixth edge, shared by the second planar face and the fourth face;
a seventh edge, shared by the third face and the fourth face, and
an outlet opening, formed in the third face, wherein the outlet opening is in communication with the inlet opening of the body; and

a channel, extending from the inlet opening to the outlet opening.

2. The sealant-applicator tip according to claim 1 , wherein the third edge of the third face is linear and lies in the virtual flat plane, the third face is planar, and the third face is oblique to the first planar face and to the second planar face.

3. The sealant-applicator tip according to claim 1 , wherein the virtual flat plane, containing the first linear edge of the first planar face and the second linear edge of the second planar face, is perpendicular to the plane of symmetry of the body.

4. The sealant-applicator tip according to claim 1 , wherein the virtual flat plane, containing the first linear edge of the first planar face and the second linear edge of the second planar face, is oblique to the plane of symmetry of the body.

5. The sealant-applicator tip according to claim 1 , wherein the head further comprises an eighth edge, shared between the first planar face and the third face.

6. The sealant-applicator tip according to claim 1 , wherein the head further comprises a ninth edge, shared between the second planar face and the third face.

7. The sealant-applicator tip according to claim 1 , wherein the outlet opening of the head has a perimeter edge and an axis of symmetry, and wherein the perimeter edge comprises:
a linear segment, adjacent to the third edge of the third face;
a first curved segment, extending from the linear segment toward the seventh edge of the head; and
a second curved segment, extending from the linear segment to the first curved segment, and wherein:
the axis of symmetry bisects the linear segment, and
the first curved segment and the second curved segment are symmetric about the axis of symmetry.

8. The sealant-applicator tip according to claim 7 , wherein the axis of symmetry of the outlet opening bisects the third face in two equal halves.

9. The sealant-applicator tip according to claim 7 , wherein the third face comprises a truncated triangular shape.

10. The sealant-applicator tip according to claim 1 , wherein:
the body defines a channel-body portion of the channel,
the head defines a channel-head portion of the channel, and
the channel-head portion is in communication with the channel-body portion.

11. The sealant-applicator tip according to claim 10 , wherein:
the channel further comprises a channel interface, connecting the channel-body portion and the channel-head portion,
at least a portion of the channel-body portion tapers inwardly from the inlet opening of the body to the channel interface, and
at least a portion of the channel-head portion tapers outwardly from the channel interface to the outlet opening of the head.

12. The sealant-applicator tip according to claim 10 , further comprising an O-ring, located in the channel-body portion of the channel.

13. The sealant-applicator tip according to claim 12 , wherein:
the body further comprises an internal annular shoulder formed in the channel-body portion of the channel, and
the O-ring is received by the internal annular shoulder.

14. The sealant-applicator tip according to claim 1 , wherein the first planar face has a triangular shape.

15. The sealant-applicator tip according to claim 1 , wherein the second planar face has a triangular shape.

16. The sealant-applicator tip according to claim 1 , wherein the body comprises a medial axis, comprising at least one inflection point.

17. The sealant-applicator tip according to claim 1 , further comprising a notch, extending along a portion of the body from the inlet opening.

18. The sealant-applicator tip according to claim 1 , further comprising an opposed pair of teeth, extending outwardly from the body proximate the inlet opening.

19. The sealant-applicator tip according to claim 1 , wherein:
the seventh edge of the head is linear;
the third edge of the head is linear; and
the seventh edge and the third edge are parallel to each other.

20. The sealant-applicator tip according to claim 1 , wherein each of the first planar face and the second planar face is oriented at a forty-five degree angle to the third face.
