Folding wand with fluid conduit passing through axis of rotation
An applicator for dispensing a fluid includes a housing and a pump disposed within the housing. The applicator also includes a wand rotatably coupled to the housing. The applicator further includes a conduit that extends between the pump and the wand to deliver the fluid from the pump to the wand. The wand comprises a curved portion for receiving the conduit. The conduit, when disposed in the curved portion, intersects an axis about which the wand rotates.

6. The applicator of claim 5 , wherein when the wand is urged from a first position to a second position, a force of the resilient force member arrests the rotational motion of the wand until the force of the resilient force member is overcome by the protrusion moving from the position in contact with the inner surface of the detent wheel to the position in contact with the outer surface of the detent wheel.
7. The applicator of claim 5 , wherein the resilient force member is unitary with the detent wheel.
8. The applicator of claim 4 , comprising:
a nozzle attached to an end of the wand, wherein the conduit extends between the pump and the nozzle to deliver the fluid from the pump to the nozzle at the end of the wand.

10. The applicator of claim 9 , wherein the second portion is located between the first portion and the third portion.
11. The applicator of claim 9 , wherein:
the conduit extends along a conduit central axis, and
the conduit central axis, at the second portion, is colinear with the fold axis such that the conduit rotates about the conduit central axis when the wand is moved from the first position to the second position.
12. The applicator of claim 9 , comprising:
a nozzle attached to an end of the wand, wherein the conduit extends between the pump and the nozzle to deliver the fluid from the pump to the nozzle at the end of the wand.
13. The applicator of claim 9 , wherein the wand is rotatable through an angle of about 180° relative to the housing.
14. An applicator for dispensing a fluid, comprising:
a housing;
a pump disposed within the housing;
a wand rotatably coupled to the housing, the wand defining a duct and the wand comprising:
a curved portion at an end of the wand;
a conduit extending between the pump and the wand to deliver the fluid from the pump to the wand, the conduit comprising:
a first portion disposed in the housing,
a second portion disposed in the curved portion, and
a third portion disposed in the duct, wherein:
the wand is rotatable about a fold axis from a first position relative to the housing to a second position relative to the housing,
when in the first position, a conduit path of the conduit from the first portion to the third portion has a first length,

the first length is equal to the second length,
a first bracket cooperating with the conduit to provide a physical interference to inhibit the first portion from rotating about the fold axis; and
a second bracket cooperating with the conduit to provide a second physical interference spaced a distance from the first bracket to inhibit the first portion from rotating about the fold axis about which the wand rotates relative to the housing.
15. The applicator of claim 14 , wherein the second bracket is a groove located in a cooperating structure of the housing.
16. The applicator of claim 14 , wherein the fold axis is colinear with a conduit central axis of the conduit.
