Abstract

A fluid cartridge assembly includes a fluid cartridge and a cap. The fluid cartridge includes a cartridge body and a flange extending from the cartridge body. The cap includes a locking latch, first and second squeeze handles, and a lever. The locking latch is configured to engage the flange of the fluid cartridge to couple the cap to the cartridge. The first squeeze handle being operatively coupled to said locking latch and configured to be depressed in a radially inward direction toward said second squeeze handle causing said locking latch to move in a radially outward direction. The lever is coupled to at least one of the first and second squeeze handles and configured to move between two positions. In one position the squeeze handles are substantially prevented from moving in the radially inward direction, and in another position the squeeze handles can move freely in the radially inward direction.

First claim

What is claimed is:

1 . A cap for sealing a cartridge containing fluid, the cap comprising:
a cap body; a locking latch extending at least partially in a proximal direction from said cap body, said locking latch configured to engage a flange of the cartridge to secure the cap to the cartridge; first and second squeeze handles extending at least partially in a distal direction from said cap body, said first squeeze handle being operatively coupled to said locking latch and configured to be depressed in a radially inward direction toward said second squeeze handle, wherein when said first squeeze handle is depressed in the radially inward direction said locking latch moves in a radially outward direction; and a lever coupled to at least one of said first and second squeeze handles and positioned between said first and second squeeze handles, said lever configured to move between a first position and a second position, wherein in the first position said first and second squeeze handles are substantially prevented from moving in the radially inward direction, and wherein in the second position said first and second squeeze handles can move freely in the radially inward direction.

2 . The cap of claim 1 , wherein e locking latch is a first locking latch, the cap further comprising:
a second locking latch extending at least partially in the proximal direction from said cap body, said second locking latch configured to engage a second flange of the cartridge to further secure the cap to the cartridge, second locking latch being positioned on an opposing side of said cap body from said first locking latch, wherein said second squeeze handle is operatively coupled to said second locking latch and configured to be depressed in a radially inward direction toward said first squeeze handle, wherein when said second squeeze handle is depressed in the radially inward direction said second locking latch moves in a radially outward direction.

3 . The cap of claim 1 , wherein said cap body comprises a closed distal wall and an annular wall, said locking latch and said first and second squeeze handles being coupled to the closed distal wall, the annular wall extending from the closed distal wall in the proximal direction, the annular wall defining a substantially cylindrical receiving channel.

4 . The cap of claim 3 , wherein the annular wall includes at least one slot that extends through the annular wall from a proximal end of the annular wall towards the closed distal wall.

5 . The cap of claim 3 , wherein the cap body further comprises a fluid inlet wall, the fluid inlet wall extending from the closed distal wall in the proximal direction, the fluid inlet wall being positioned within the receiving channel, the fluid inlet wall having an inner surface that defines a substantially cylindrical fluid channel within and an outer surface that defines a shoulder thereon.

6 . The cap of claim 3 , wherein the annular wall is a first annular wall and the receiving channel is a first receiving channel, wherein said cap body further comprises a second annular wall extending from the closed distal wall in the proximal direction, the second annular wall defining a second receiving channel that is substantially cylindrical.

7 . The cap of claim 1 , wherein said cap body, said locking latch, said first and second squeeze handles, and said lever are molded together forming a unitary cap.

8 . The cap of claim 1 , wherein said lever is rigidly coupled to said first squeeze handle and releasably coupled to said second squeeze handle, wherein a force applied to said lever in the proximal direction transitions said lever from the first position to the second position such that said lever is de-coupled from said second squeeze handle.

9 . The cap of claim 1 , wherein said locking latch comprises an orientation rib attached thereto, the orientation rib extending at least partially radially outward from said locking latch.

10 . The cap of claim 8 , wherein a proximal end of said orientation rib extends beyond a proximal end of said locking latch in the proximal direction.

11 . A fluid cartridge assembly comprising:
a fluid cartridge comprising:
a cartridge body, and
a flange extending outwardly from said cartridge body; and
a cap configured to couple to said fluid cartridge, the cap comprising:
a cap body,
a locking latch extending at least partially in a proximal direction from said cap body, said locking latch configured to engage said flange of said fluid cartridge to couple said cap to said cartridge,
first and second squeeze handles extending at least partially in a distal direction from said cap body, said first squeeze handle being operatively coupled to said locking latch and configured to be depressed in a radially inward direction toward said second squeeze handle, wherein when said first squeeze handle is depressed in the radially inward direction said locking latch moves in a radially outward direction, and
a lever coupled to at least one of said first and second squeeze handles and positioned between said first and second squeeze handles, said lever configured to move between a first position and a second position, wherein in the first position said first and second squeeze handles are substantially prevented from moving in the radially inward direction, and wherein in the second position said first and second squeeze handles can move freely in the radially inward direction.

12 . The assembly of claim 11 , wherein said cap body comprises a closed distal wall and a cap annular wall, said locking latch and said first and second squeeze handles being coupled to the closed distal wall, the cap annular wall extending from the closed distal wall in the proximal direction, the cap annular wall defining a substantially cylindrical receiving channel, and
wherein said fluid cartridge further comprises a cartridge annular wall extending from a distal end of said cartridge body in the distal direction, the cartridge annular wall configured to be received within the cap annular wall.

13 . The assembly of claim 12 , wherein the cap annular wall includes at least one slot that extends through the cap annular wall from a proximal end of the cap annular wall towards the closed distal wall, and wherein the cartridge annular wall includes at least one radial projection, wherein each of the at least one radial projections corresponds to a respective at least one slot of said cap annular wall such that when said cap is coupled to said fluid cartridge each at least one radial projection is positioned at least partially within a respective at least one slot.

14 . The assembly of claim 12 , wherein said cap body further comprises a fluid inlet wall, the fluid inlet wall extending from the closed distal wall in the proximal direction, the fluid inlet wall being positioned within the receiving channel, the fluid inlet wall having an inner surface that defines a substantially cylindrical fluid channel within and an outer surface that defines a shoulder thereon, and
wherein said fluid cartridge further comprises a fluid outlet wall, the fluid outlet wall extending from the distal end of the said cartridge body in the distal direction, the fluid outlet wall configured to be received within the receiving channel of the annular cap wall and about the fluid inlet wall, wherein when said cap is coupled to said fluid cartridge a distal end of the fluid outlet wall contacts the shoulder of the fluid inlet wall.

15 . The assembly of claim 11 , wherein said locking latch comprises an orientation rib, the orientation rib extending at least par
