Abstract

An applicator assembly includes a head portion having a proximal end, a distal end, and an interior portion defining a fluid chamber, a container slidably coupled to the head portion, a plug sealing an end of the container, an application member attached to the distal end, and one or more orifices formed through a surface of the plug, wherein the plug is mounted in the interior portion of the head portion and an interior of the container is placed in fluid communication with the application member by way of a fluid conduit that is formed through the plug from the container to the fluid chamber when the container is axially translated toward the head portion to bring the one or more orifices into fluid communication with the container.

First claim

What is claimed is:

1. An applicator assembly comprising:
a head portion having a proximal end, a distal end, and an interior portion defining a fluid chamber;
a container comprising a sealing ring, wherein the container is slidably coupled to the head portion;
plug sealing an end of and extending into the container prior to actuation of the container,
a foam application member attached to the distal end; and
one or more orifices formed through a surface of the plug, and
wherein an interior of the container is placed in fluid communication with the application member by way of a fluid conduit that is formed through the plug from the container to the fluid chamber when the container is actuated into the proximal end of the head portion to bring an area of the one or more orifices into fluid communication with the container by moving the sealing ring relative to the plug,
wherein the container is configured to translate relative to the head portion during use such that the area of the one or more orifices is variable during use.

2. The applicator assembly of claim 1 , further comprising a mechanical stop to secure the container in a predetermined position until the stop is released prior to actuation of the container.

3. The applicatory assembly of claim 2 , wherein the actuation of the container comprises axial translation.

4. The applicator assembly of claim 2 , wherein the mechanical stop comprises a hinged portion disposed toward the proximal end of the head portion or toward an insertion end of the container.

5. The applicator assembly of claim 4 , wherein the mechanical stop further comprises a securing mechanism to retard axial translation of the container.

6. The applicator assembly of claim 5 , wherein the securing mechanism comprises a snap fit channel for engaging a first retention mechanism on an exterior of the container to secure the applicator assembly in a storage position.

7. The applicator assembly of claim 2 , wherein the mechanical stop comprises a circumferentially extending surface portion connected to the proximal end of the head portion and a distal end of the container.

8. The application assembly of claim 7 , wherein the circumferentially extending surface portion is disposed within a gap between the proximal end of the head portion and the distal end of the container.

9. The applicator assembly of claim 1 , wherein the plug comprises a hollow body portion.

10. The applicator assembly of claim 9 , wherein one or more orifices provide fluid communication from an exterior portion of the plug into the hollow body portion when the container translates toward the distal end of the head portion.

11. The applicator assembly of claim 1 , further comprising a second retention mechanism provided on a surface of the plug, wherein the second retention mechanism retards axial translation of the container.

12. The applicator assembly of claim 11 , wherein the second retention mechanism is disposed between the one or more orifices and the distal end of the head portion.

13. The applicator assembly of claim 1 , wherein the plug extends axially within the container.

14. The applicator assembly of claim 1 , wherein the sealing ring prevents fluid communication between the container and the one or more orifices before the container translates towards the distal end of the head portion.

15. The applicator assembly of claim 1 , wherein the one or more orifices comprises a pair of orifices opposing each other.

16. The applicator assembly of claim 1 , wherein the plug is integrally formed with the distal end of the head portion.

17. The applicator assembly of claim 11 , wherein the second retention mechanism comprises an annular retention ring.

18. The applicator assembly of claim 1 , wherein the foam application member has a perimeter larger than a perimeter of the distal end of the container.

19. The applicator assembly of claim 1 , further comprising a mounting flange at the distal end of the container, wherein the foam application member is affixed to the mounting flange, and wherein the application member has a perimeter larger than the perimeter of the mounting flange.

20. The applicator assembly of claim 1 , wherein the foam application member comprises a porous material having a soak rate sufficient to distribute solution through the application member.

21. The applicator assembly of claim 1 , wherein the container comprises an antiseptic solution.

22. The applicator assembly of claim 21 , wherein the antiseptic solution comprises an antimicrobial agent selected from the group consisting of octenidine salts, chlorhexidine salts, alcohols, aldehydes, anilides, diamidines, halogen-releasing agents, sliver compounds, peroxygens, and phenols.

23. The applicator assembly of claim 22 , wherein the antiseptic solution comprises an octenidine salt or a chlorhexidine salt.
