Abstract

The present disclosure relates to connectors that may be employed in cartridges for smoking articles. The connectors may include a single-use mechanism that may include a blocking pin, a biasing mechanism, and a release mechanism. The release mechanism may hold the blocking pin in a partially retracted position in which the blocking pin is at least partially retracted from an aperture extending through threads defined by the connector. The release mechanism may include a latch that is displaced from contact with the blocking pin by a release pin upon engagement of the connector with a mating connector. The biasing mechanism may force the blocking pin against an end of the mating connector such that when the mating connector is unscrewed from the connector, the blocking pin extends through the aperture and blocks at least one recess defined between the threads such that the connector may not be reused.

Claims

1. A single-use connector, comprising:

a body, defining;

a plurality of threads;

a plurality of recesses respectively positioned between the threads; and

an aperture extending through one or more of the threads; and

a single-use mechanism, comprising;

a blocking pin configurable between a retracted position in which the blocking pin is at least partially retracted from the aperture and an extended position in which the blocking pin extends through the aperture and blocks at least one of the recesses;

a biasing mechanism configured to bias the blocking pin toward the extended position; and

a release mechanism configured to retain the blocking pin in the retracted position and release the blocking pin after the threads and the recesses engage a mating connector.

2. The single-use connector of claim 1, wherein is the threads and the recesses are defined at an inner surface of the body surrounding a cavity configured to receive the mating connector.

3. The single-use connector of claim 1, wherein the threads and the recesses are defined at an outer surface of the body and configured to be received in a cavity defined by the mating connector.

4. The single-use connector of claim 1, wherein the release mechanism comprises:

a latch configured to engage the blocking pin to retain the blocking pin in the retracted position; and

a release pin configured to release the latch from engagement with the blocking pin.

5. The single-use connector of claim 4, wherein the blocking pin defines a head and the latch is configured to engage the head of the blocking pin and pivot out of contact therewith upon being displaced by the release pin.

6. The single-use connector of claim 5, wherein the release pin defines a tapered end configured to engage the latch.

7. The single-use connector of claim 6, wherein the release pin is configured to engage an end of the mating connector when the threads and the recesses engage the mating connector.

8. The single-use connector of claim 1, wherein the biasing mechanism comprises a coil spring.

9. A single-use cartridge, comprising:

a chamber configured to hold a product; and

a connector, comprising;

a body, defining;

a plurality of threads;

a plurality of recesses respectively positioned between the threads; and

an aperture extending through one or more of the threads; and

a single-use mechanism, comprising;

a blocking pin configurable between a retracted position in which the blocking pin is at least partially retracted from the aperture and an extended position in which the blocking pin extends through the aperture and blocks at least one of the recesses;

a biasing mechanism configured to bias the blocking pin toward the extended position; and

a release mechanism configured to retain the blocking pin in the retracted position and release the blocking pin after the threads and the recesses engage a mating connector.

10. The single-use cartridge of claim 9, wherein the threads and the recesses are defined at an inner surface of the body surrounding a cavity configured to receive the mating connector.

11. The single-use cartridge of claim 9, wherein the threads and the recesses are defined at an outer surface of the body and configured to be received in a cavity defined by the mating connector.

12. The single-use cartridge of claim 9, wherein the release mechanism comprises:

a latch configured to engage the blocking pin to retain the blocking pin in the retracted position; and

a release pin configured to release the latch from engagement with the blocking pin.

13. The single-use cartridge of claim 12, wherein the blocking pin defines a head and the latch is configured to engage the head of the blocking pin and pivot out of contact therewith upon being displaced by the release pin.

14. The single-use cartridge of claim 13, wherein the release pin defines a tapered end configured to engage the latch.

15. The single-use cartridge of claim 14, wherein the release pin is configured to engage an end of the mating connector when the threads and the recesses engage the mating connector.

16. The single-use cartridge of claim 9, wherein the biasing mechanism comprises a coil spring.

17. The single-use cartridge of claim 9, wherein the product comprises an aerosol precursor composition.

18. A method for assembling a connector, comprising:

providing a body defining a plurality of threads, a plurality of recesses, and an aperture extending through one or more of the threads;

providing a single-use mechanism comprising a blocking pin, a release mechanism, and a biasing mechanism;

coupling the single-use mechanism to the body such that the blocking pin is in a retracted position wherein the blocking pin is at least partially retracted from the aperture by the release mechanism, wherein upon disengagement of the threads and recesses from a mating connector the release mechanism releases the blocking pin and the biasing mechanism biases the blocking pin to an extended configuration in which the blocking pin extends through the aperture and blocks at least one of the recesses.

19. The method of claim 18, wherein coupling the single-use mechanism to the body comprises coupling a coil spring to the body and the blocking pin.

20. The method of claim 19, wherein coupling the single-use mechanism to the body further comprises retracting the blocking pin to the retracted position and engaging the blocking pin with a latch.

21. The method of claim 20, wherein coupling the single-use mechanism to the body further comprises positioning a release pin in an extended position configured to engage the mating connector and release the latch from the blocking pin upon engagement therewith.
