Abstract

The present disclosure provides inventive nozzles and applicators for dispensing adhesive. These nozzle comprise: a main body cavity and a cap releasably attached to the main body cavity; wherein the cap includes spaced orifices for dispensing adhesive on an outer surface of a male pipe and a sleeve extending inwardly from the cap into the main body cavity; wherein the main body cavity includes a barrel portion, a funnel portion and a conduit, and wherein the sleeve is sized to accommodate the outer surface of a selected male pipe.

First claim

1 - 22 . (canceled)

23 . A nozzle for dispensing adhesive, comprising:
a main body cavity and a sleeve is sized to accommodate the outer surface of a selected male pipe; wherein the main body cavity includes a barrel portion, a funnel portion and a conduit;
wherein the main body cavity and sleeve form a spaced opening for dispensing adhesive on the outer surface of a male pipe, wherein the spaced opening is an annularly spaced ring;
a channel for an adhesive to flow through from the conduit to the spaced opening, wherein the channel is formed between sleeve and the funnel and barrel portions.

24 . (canceled)

25 . The nozzle of claim 23 , wherein the annular spaced ring is sized for dispensing adhesive on the outer surface of a male pipe of desired size.

26 . The nozzle of claim 23 , wherein the annular spaced opening includes a plurality of annular spaced openings.

27 . The nozzle of claim 26 , wherein the main body cavity has an axis, and the annular spaced openings are at an angle of between 5 and 85 degrees relative to the axis.

28 . The nozzle of claim 27 , wherein the spaced orifices are at an angle of between 30 and 75 degrees relative to the axis of the main body cavity.

29 . The nozzle of claim 28 , wherein the spaced orifices are at an angle of between 20 and 45 degrees relative to the axis of the main body cavity.

30 . The nozzle of claim 23 , further including an adhesive, wherein the adhesive is dispensed through the spaced orifices in a sleeve-like coating.

31 . The nozzle of claim 30 , wherein the conduit is in fluid communication with the funnel portion, the funnel portion is in fluid communication with the barrel portion, wherein the adhesive flows from the conduit through the funnel portion through the barrel portion and is dispensed through the spaced opening.

32 - 39 . (canceled)

40 . The nozzle of claim 23 , further including an adhesive, wherein the adhesive is dispensed through the spaced orifices and wherein the adhesive comprises a 1-part (1K) epoxy adhesive.

41 . The nozzle of claim 23 , further including an adhesive, wherein the adhesive is dispensed through the spaced orifices and wherein the adhesive comprises a 2-part (2K) epoxy adhesive.

42 . The nozzle of claim 23 , further including an adhesive, wherein the adhesive is dispensed through the spaced orifices and wherein the adhesive comprises a structural adhesive composition comprising:
a resin; and from 0.1 to 5 wt % of one or more compounds of formula I

wherein x is an integer from 1 to 4,
y is an integer from 2 to 6, and
z is an integer from 1 to 6.

43 . The nozzle of claim 42 , wherein the resin comprises an epoxy resin.

44 . The nozzle of claim 42 , wherein the compound of formula I is Bis[3-(triethoxysilyl) propyl] disulfide.

45 . The nozzle of claim 42 , wherein the compound of formula I is Bis[3-(triethoxysilyl) propyl] tetrasulfide.

46 . The nozzle of claim 42 , wherein the structure adhesive composition comprises acrylic adhesive, 1K urethane adhesive, 2K urethane adhesive, or combinations thereof.

47 . A dual nozzle for dispensing adhesive, comprising:
a first main body cavity and a first cap releasably attached to the main body cavity; wherein the first cap includes spaced orifices for dispensing adhesive on an outer surface of a first male pipe and a first sleeve extending from the first cap; wherein the first main body cavity includes a barrel portion, a funnel portion and a conduit, and wherein the first sleeve is sized to accommodate the outer surface of a first male pipe; and a second main body cavity and a second cap releasably attached to the first main body cavity; wherein the second cap includes spaced orifices for dispensing adhesive on an outer surface of a second male pipe and a first sleeve extending from the second cap; wherein the second main body cavity includes a barrel portion, a funnel portion and a conduit, and wherein the second sleeve is sized to accommodate the outer surface of a second male pipe.

48 . The dual nozzle of claim 47 wherein the first sleeve extends inwardly toward the barrel portion of the first main body cavity; and wherein the second sleeve extends inwardly toward the barrel portion of the second main body cavity.

49 . The dual nozzle of claim 47 , wherein the orifices are annularly spaced orifices.

50 . The dual nozzle of claim 49 , wherein the main body cavity has an axis, and the spaced orifices are at an angle of between 5 and 85 degrees relative to the axis.

51 . The dual nozzle of claim 50 , wherein the spaced orifices are at an angle of between 30 and 75 degrees relative to the axis of the main body cavity.

52 . The dual nozzle of claim 51 , wherein the spaced orifices are at an angle between 20 and 45 degrees relative to the axis of the main body cavity.

53 . (canceled)

54 . The dual nozzle of claim 53 , wherein the conduit is in fluid communication with both of the funnel portions of the first main body cavity and the second main body cavity, wherein the funnel portion of the first main body cavity is in fluid communication with the barrel portion of the first main body cavity, wherein the funnel portion of the second main body cavity is in fluid communication with the barrel portion of the second main body cavity, wherein the adhesive flows from the conduit through the funnel portion through the barrel portion of the first main body cavity and is dispensed through the spaced orifices of the first cap, and wherein the adhesive flows from the conduit through the funnel portion through the barrel portion of the second main body cavity and is dispensed through the spaced orifices of the second cap.

55 - 63 . (canceled)

64 . The dual nozzle of claim 47 , further including an adhesive, wherein the adhesive is dispensed through the spaced orifices of the first cap and second cap, and wherein the adhesive comprises a 1-part (1K) epoxy adhesive.

65 . The dual nozzle of claim 47 , further including an adhesive, wherein the adhesive is dispensed through the spaced orifices of the first cap and second cap, and wherein the adhesive comprises a 2-part (2K) epoxy adhesive.
