Abstract

A cartridge insertion assembly including apparatus with a pathway formed therein, a cartridge insertable into the pathway, the cartridge including a cartridge coupling element connectable to an activation mechanism disposed in the apparatus operative to cause a substance contained in the cartridge to be metered out of the cartridge, and a door pivoted to the apparatus that includes a door coupling element arranged with respect to the cartridge such that when the door is in a fully closed position, the door coupling element couples the cartridge coupling element with a coupling element of the activation mechanism.

Claims

1. A cartridge insertion assembly comprising:

an apparatus with a pathway formed therein;

a cartridge insertable into said pathway, said cartridge comprising a cartridge coupling element connectable to an activation mechanism disposed in said apparatus operative to cause a substance contained in said cartridge to be metered out of said cartridge; and

a door pivoted to said apparatus that comprises a door coupling element arranged with respect to said cartridge such that when said door is in a fully closed position, said door coupling element couples said cartridge coupling element with a coupling element of said activation mechanism.

2. The cartridge insertion assembly according to claim 1, further comprising a locking latch cantilevered from a base of said apparatus, wherein when said cartridge is fully inserted in said apparatus, said locking latch abuts against a rim of said cartridge, thereby locking said cartridge in said pathway.

3. The cartridge insertion assembly according to claim 1, wherein when said cartridge is fully inserted in said apparatus, said cartridge abuts against a cartridge stopper disposed in said apparatus.

4. The cartridge insertion assembly according to claim 1, wherein said cartridge comprises a septum at an end opposite to said cartridge coupling element, and said apparatus comprises a hollow needle, wherein when said cartridge is fully inserted in said apparatus, said needle punctures said septum.

5. The cartridge insertion assembly according to claim 1, wherein said door comprises a closure member on an inside surface thereof, said closure member comprising one or more inclined ramp members, wherein closing said door causes said ramp members to slide and push against said cartridge coupling element so as to push said cartridge fully into said apparatus.

6. The cartridge insertion assembly according to claim 1, wherein said door is formed with one or more ribs, which when said door is fully closed, said ribs are received in one or more corresponding grooves formed in said apparatus.

7. The cartridge insertion assembly according to claim 1, wherein said door comprises a closure member on an inside surface thereof, said closure member comprising a hub, wherein when said door is fully closed, said hub is fixedly received in a snap member.

8. The cartridge insertion assembly according to claim 1, wherein said coupling elements comprise gears.

9. A cartridge insertion assembly comprising:

apparatus with a pathway formed therein;

a cartridge insertable into said pathway, said cartridge comprising a cartridge coupling element connectable to an activation mechanism disposed in said apparatus operative to cause a substance contained in said cartridge to be metered out of said cartridge; and

a door pivoted to said apparatus that comprises a door coupling element sized and shaped to transmit rotary motion, said door coupling element being arranged with respect to said cartridge such that when said door is in a fully closed position, said door coupling element couples said cartridge coupling element with a coupling element of said activation mechanism.

10. The cartridge insertion assembly according to claim 9, further comprising a locking latch cantilevered from a base of said apparatus, wherein when said cartridge is fully inserted in said apparatus, said locking latch abuts against a rim of said cartridge, thereby locking said cartridge in said pathway.

11. The cartridge insertion assembly according to claim 9, wherein when said cartridge is fully inserted in said apparatus, said cartridge abuts against a cartridge stopper disposed in said apparatus.

12. The cartridge insertion assembly according to claim 9, wherein said cartridge comprises a septum at an end opposite to said cartridge coupling element, and said apparatus comprises a hollow needle, wherein when said cartridge is fully inserted in said apparatus, said needle punctures said septum.

13. The cartridge insertion assembly according to claim 9, wherein said door comprises a closure member on an inside surface thereof, said closure member comprising one or more inclined ramp members, wherein closing said door causes said ramp members to slide and push against said cartridge coupling element so as to push said cartridge fully into said apparatus.

14. The cartridge insertion assembly according to claim 9, wherein said door is formed with one or more ribs, which when said door is fully closed, said ribs are received in one or more corresponding grooves formed in said apparatus.

15. The cartridge insertion assembly according to claim 9, wherein said door comprises a closure member on an inside surface thereof, said closure member comprising a hub, wherein when said door is fully closed, said hub is fixedly received in a snap member.

16. The cartridge insertion assembly according to claim 9, wherein said coupling elements comprise gears.

17. A cartridge insertion assembly comprising:

an apparatus with a pathway formed therein;

a cartridge insertable into said pathway, said cartridge comprising a cartridge coupling element connectable to an activation mechanism disposed in said apparatus operative to cause a substance contained in said cartridge to be metered out of said cartridge;

a door pivoted to said apparatus that comprises a door coupling element arranged with respect to said cartridge such that when said door is in a fully closed position, said door coupling element couples said cartridge coupling element with a coupling element of said activation mechanism; and

a locking latch cantilevered from a base of said apparatus, wherein when said cartridge is fully inserted in said apparatus, said locking latch abuts against a rim of said cartridge, thereby locking said cartridge in said pathway, and wherein when said cartridge is fully inserted in said apparatus, said cartridge abuts against a cartridge stopper disposed in said apparatus.
