means for inserting tampons A61F13/26; devices for administering food or medicines orally A61J; containers for collecting, storing or administering blood or medical fluids A61J1/05); DEVICES FOR TRANSDUCING BODY MEDIA OR FOR TAKING MEDIA FROM THE BODY (surgery A61B; chemical aspects of surgical articles A61L); DEVICES FOR PRODUCING OR ENDING SLEEP OR STUPOR {(Electrotherapy, e.g. producing anaesthesia by the use of alternating or intermittent currents A61N1/36021)} ## Abstract An applicator assembly includes a head portion having a proximal, a distal end, and an interior portion defining a fluid chamber, a container slidably coupled to the body, a breakable membrane sealing an end of the container, and a hollow puncture mechanism, wherein the hollow puncture mechanism 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 hollow puncture mechanism from the container to the fluid chamber when the container is axially translated toward the head portion and the puncture mechanism pierces the breakable membrane. ## Claims ### Claim 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 slidably coupled to the head portion; a breakable membrane sealing an end of the container; an application member attached to the distal end; and a hollow puncture mechanism, wherein the puncture mechanism 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 hollow puncture mechanism from the container to the fluid chamber when the container is axially translated toward the head portion and the puncture mechanism pierces the breakable membrane. ### Claim 2 (depends on 1) The applicator assembly of claim 1, further comprising a closing member sealing the other end of the container from the end having the breakable membrane. ### Claim 3 (depends on 2) The applicator assembly of claim 2, wherein the closing member is separable from the container. ### Claim 4 (depends on 3) The applicator assembly of claim 3, wherein the closing member is connected to the container via a threaded connection. ### Claim 5 (depends on 1) The applicator assembly of claim 1, further comprising an annular retention ring provided on an exterior of a sidewall of the container for mating with a first annular retention channel configured into an interior of the head portion to apply resistance to the axial movement of the container in relation to the head portion. ### Claim 6 (depends on 5) The applicator assembly of claim 5, further comprising a second annular retention channel configured into the interior of the head portion and disposed closer toward the distal end than the first annular retention channel. ### Claim 7 (depends on 1) 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 applicator. ### Claim 8 (depends on 7) The applicator assembly of claim 7, wherein the mechanical stop comprises a hinged portion of the proximal portion of the head portion. ### Claim 9 (depends on 8) The applicator assembly of claim 8, wherein the mechanical stop further comprises a securing mechanism to prevent axial translation of the container. ### Claim 10 (depends on 9) The applicator assembly of claim 9, wherein the securing mechanism comprises a snap fit channel for engaging a retention ring on an exterior of the container to secure the applicator assembly in a storage position when the mechanical stop is pressed against the container. ### Claim 11 (depends on 8) The applicator assembly of claim 8, wherein the securing mechanism comprises a detent that engages an insertion end of the container. ### Claim 12 (depends on 1) The applicator assembly of claim 1, wherein the hollow puncture mechanism comprises a hollow tip portion and a hollow body portion. ### Claim 13 (depends on 12) The applicator assembly of claim 12, wherein the hollow puncture mechanism further comprises support struts that extend radially from the hollow body portion to secure the hollow puncture mechanism at a predetermined position in the head portion. ### Claim 14 (depends on 12) The applicator assembly of claim 12, wherein the tip portion pierces the breakaway membrane when the container translates toward the distal end of the head portion. ### Claim 15 (depends on 12) The applicator assembly of claim 12, wherein the hollow puncture mechanism comprises a transverse fluid conduit to provide fluid communication from an exterior portion of the puncture mechanism into the hollow puncture mechanism. ### Claim 16 (depends on 15) The applicator assembly of claim 15, wherein the transverse fluid conduit comprises a gap extending longitudinally along the hollow tip portion and the hollow body portion.
