Abstract

An adhesive discharge cap for handheld adhesive sealant tubes that includes a cap body having an outer sidewall with an upper terminal end, a lower terminal end defining a lower opening and an outer surface and an inner surface defining a threaded coupling configuration surrounding the inner surface of the outer sidewall. The cap includes a sealant discharge conduit coupled to the cap body, with a lower terminal conduit end defining a lower conduit opening, an upper terminal conduit end defining an upper conduit opening, a conduit inner surface defining a conduit channel from upper to lower end of the conduit, with a conduit outer surface and defining, with the inner surface of the cap body, and a tube receiving channel surrounding the sealant discharge conduit, wherein the lower terminal conduit end is spatially offset a length below the lower terminal end of the cap body and the upper terminal conduit end spatially offset a length above the upper terminal end of the cap body.

Claims (25)

1. An adhesive discharge cap for handheld adhesive sealant tubes comprising:

a cap body having an outer sidewall with:

an upper terminal end, a lower terminal end opposing the upper terminal end and defining a lower opening;

a cap body length separating the upper and lower terminal ends of the cap body; and

an outer surface and an inner surface defining a threaded coupling configuration surrounding the inner surface of the outer sidewall; and

a sealant discharge conduit coupled to the cap body, with a lower terminal conduit end defining a lower conduit opening, an upper terminal conduit end opposing the lower terminal conduit end and defining an upper conduit opening, a conduit length separating the lower terminal conduit end and the upper terminal conduit end, with a conduit inner surface defining a conduit channel spanning the conduit length, with a conduit outer surface opposing the conduit inner surface and defining, with the inner surface of the cap body, and a tube receiving channel surrounding the sealant discharge conduit and spanning along the cap body length from the lower opening of the cap body to an internal wall disposed within the cap body, wherein the lower terminal conduit end is spatially offset a length between approximately 10-50 mm below the lower terminal end of the cap body with the entire lower conduit opening disposed below the lower terminal end of the cap body and the upper terminal conduit end spatially offset a length above the upper terminal end of the cap body, wherein the cap body and the discharge conduit are of a monolithic structure.

2. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 1 , wherein the outer surface further comprises:

a plurality of ridges radially extending the outer surface of the outer sidewall and configured to provide a gripping surface for a user.

3. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 1 , wherein the sealant discharge conduit tapers in diameter proximal to the lower terminal tube end.

4. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 1 , wherein the cap body and the sealant discharge conduit are of a polymeric material including at least one of polypropylene, polyethylene, ABS plastic, or nylon.

5. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 1 , wherein at least 10% of the conduit length is spatially offset a length below the lower terminal end of the cap body and at least 10% of the conduit length is spatially offset a length above the upper terminal end of the cap body.

6. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 1 , wherein the lower terminal end of the cap body defines a lower cap plane, the sealant discharge conduit oriented at a perpendicular angle relative to the lower cap plane.

7. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 1 , wherein the sealant discharge conduit further comprises a flange radially extending outwardly from the conduit outer surface, directly coupled with the inner surface of the cap body, and defining the internal wall defining an internal inner limit of the tube receiving channel.

8. The adhesive discharge cap for handheld adhesive sealant tubes according to claim 7 , wherein the flange is threadedly coupled to the threaded coupling configuration defined by the inner surface of the cap body.

9. In combination with a handheld adhesive sealant tube operably configured to house an adhesive sealant within an enclosed tube cavity defined by the handheld adhesive sealant tube, having an upper end defining a tube opening for discharging the adhesive sealant, and defining a threaded configuration proximal to the upper end of the upper end of the handheld silicone adhesive sealant tube, the improvement comprising:

a cap body having an outer sidewall with an upper terminal end, with a lower terminal end opposing the upper terminal end and defining a lower opening, with a cap body length separating the upper and lower terminal ends of the cap body, and with an outer surface and with an inner surface defining a threaded coupling configuration surrounding the inner surface of the outer sidewall and selectively removably coupled to the threaded configuration defined by the handheld adhesive sealant tube; and

a sealant discharge conduit coupled to the cap body, with a lower terminal conduit end defining a lower conduit opening, an upper terminal conduit end opposing the lower terminal conduit end and defining an upper conduit opening, a conduit length separating the lower terminal conduit end and the upper terminal conduit end, with a conduit inner surface defining a conduit channel spanning the conduit length, with a conduit outer surface opposing the conduit inner surface and defining, with the inner surface of the cap body, and a tube receiving channel surrounding the sealant discharge conduit with the upper end of the handheld adhesive sealant tube disposed therein, wherein the lower terminal conduit end is disposed within the enclosed tube cavity with the entire lower conduit opening disposed below the lower terminal end of the cap body, spatially offset a length between approximately 10-50 mm below the lower terminal end of the cap body, and below the upper end of the handheld adhesive sealant tube and the upper terminal conduit end is spatially offset a length above the upper terminal end of the cap body and above the upper end of the handheld adhesive sealant tube, wherein the cap body and the discharge conduit are of a monolithic structure.

10. The improvement according to claim 9 , wherein the receiving channel spans along the cap body length from the lower opening of the cap body to an internal wall disposed within the cap body.

11. The improvement according to claim 9 , wherein the outer surface further comprises:

a plurality of ridges radially extending the outer surface of the outer sidewall and configured to provide a gripping surface for a user.

12. The improvement according to claim 9 , wherein the sealant discharge conduit tapers in diameter proximal to the lower terminal tube end.

13. The improvement according to claim 9 , wherein at least 10% of the conduit length is spatially offset a length below the lower terminal end of the cap body and at least 10% of the conduit length is spatially offset a length above the upper terminal end of the cap body.

14. The improvement according to claim 9 , wherein the lower terminal end of the cap body defines a lower cap plane, the sealant discharge conduit oriented at a perpendicular angle relative to the lower cap plane.

15. The improvement according to claim 9 , wherein the sealant discharge conduit further comprises a flange radially extending outwardly from the conduit outer surface, directly coupled with the inner surface of the cap body, and defining the internal wall defining an internal inner limit of the tube receiving channel.

16. The improvement according to claim 15 , wherein the flange is threadedly coupled to the threaded coupling configuration defined by the inner surface of the cap body.
