Abstract
A mechanical applicator comprises a barrel (112), a nose-piece (104), a coil (142), a container, and an elongated rod. The nose-piece is rotatably coupled to the barrel. The coil is carried within the barrel and fixed against rotation relative to at least one of the nose-piece and the barrel. The container is movably disposed in the barrel and adapted to contain a mass. The elongated rod is slidably disposed in the barrel and in operative engagement with the coil. So configured, rotating the nose-piece relative to the barrel in a first direction causes the coil to axially displace the. elongated rod and advance the mass out of the nose-piece. Moreover, rotating the nose-piece relative to the barrel in a second direction causes the coil to axially displace the elongated rod and retract the mass into the nose-piece.
Claims
1. A mechanical applicator, comprising: a barrel; a nose-piece rotatably coupled to the barrel; a coil spring carried within the barrel, at least a portion of the coil spring fixed against rotation relative to at least one of the nose-piece and the barrel; a container movably disposed in the barrel and adapted to contain a mass; and an elongated rod movably disposed in the barrel and in operative engagement with the coil spring such that displacement of the nose-piece relative to the barrel in a first rotational direction causes the coil spring to displace the elongated rod in a first axial direction for advancing amass out of the nose-piece, and such that displacement of the nose-piece relative to the barrel in a second rotational direction causes the coil spring to displace the elongated rod in a second axial direction for retracting a mass into the nose-piece.
2. The mechanical applicator according to claim 1, wherein the container comprises a sheath movably disposed within the nose-piece and the barrel.
3. The mechanical applicator according to claim 2, further comprising a plunger attached to the elongated rod, the plunger slidably disposed in the sheath and adapted to force a mass out of the sheath upon displacement of the nose-piece in the first rotational direction.
4. The mechanical applicator according to claim 1 , wherein the container comprises a cup attached to an end of the elongated rod.
5. The mechanical applicator according to any one of the preceding claims, further comprising at least one lug extending from the elongated rod and in engagement with the coil spring.
AMENDED SHEET (ARTICLE 19)
6. The mechanical applicator according to claim 5, wherein the lug extends radially outward from the elongated rod.
7. The mechanical applicator according to claim 5 or claim 6, further comprising at least two elongated ribs carried by the barrel, the elongated ribs accommodating the at least one lug therebetween for limiting rotational displacement of the elongated rod.
8. The mechanical applicator according to any one of the preceding claims, wherein the coil spring is adapted to absorb axial loads transmitted to the elongated rod.
9. A mechanical applicator, comprising: a barrel;
a nose-piece rotatably coupled to the barrel;
a cushion carried within the barrel, at least a portion of the cushion fixed against rotation relative to at least one of the nose-piece and the barrel;
a container movably disposed in the barrel and adapted to contain a mass; and
an elongated rod movably disposed in the barrel and in operative engagement with the cushion such that displacement of the nose-piece relative to the barrel in a first rotational direction causes the cushion to displace the elongated rod in a first axial direction for advancing a mass out of the nose-piece, and such that displacement of the nose-piece relative to the barrel in a second rotational direction causes the cushion to displace the elongated rod in a second axial direction for retracting a mass into the nose-piece.
AMENDED SHEET (ARTICLE 19)
10. The mechanical applicator according to claim 9, wherein the cushion comprises a coil carried within the barrel.
11. The mechanical applicator according to claim 10, wherein the coil comprises a coil spring adapted to absorb axial loads transmitted to the elongated rod.
12. The mechanical applicator according to claim 9, wherein the container comprises a sheath movably disposed within the nose-piece and the barrel.
13. The mechanical applicator according to claim 12, farther comprising a plunger attached to the elongated rod, the plunger slidably disposed in the sheath and adapted to force a mass out of the sheath upon displacement of the nose-piece in the first rotational direction.
14. The mechanical applicator according to claim 9, wherein the container comprises a cup attached to an end of the elongated rod.
15. The mechanical applicator according to any one of the preceding claims, further comprising at least one lug extending from the elongated rod and in engagement with the cushion.
AMENDED SHEET (ARTICLE 19)
21
16. The mechanical applicator according to claim 15, wherein the lug extends radially outward from the elongated rod.
17. The mechanical applicator according to claim 15 or claim 16, further comprising at least two elongated ribs carried by the barrel, the elongated ribs accommodating the at least one lug therebetween for limiting rotational displacement of the elongated rod.
