Abstract

Adapters for refilling an aerosol delivery device are provided. The adapters comprise a body having a container-side end and an opposing, device-side end that are sealably connectable with respectively a container of aerosol precursor composition and an aerosol delivery device having a refillable reservoir. The body defines a passageway between the ends for transfer of aerosol precursor composition from the container into the refillable reservoir. In one adapter, the container-side end is configured to engage a valve of the container during refilling of the reservoir, and thereby defines separate and distinct filling and mating ports. In another adapter, the device-side end includes a valve configured to engage the aerosol delivery device during refilling of the reservoir in which the airflow port of the aerosol delivery device is closed by the valve to prevent the aerosol precursor composition from passing through the airflow port.

First claim

What is claimed is:

1. An adapter for mating a container of aerosol precursor composition with an aerosol delivery device having a reservoir that is refillable, the aerosol delivery device defining separate and distinct filling and airflow ports that are elongated passageways through which liquid or air is transportable, the adapter separate and distinct from the container and the aerosol delivery device, the adapter comprising:
a body having a container-side end and an opposing, device-side end, the container-side end configured to connect with the container, and the device-side end configured to engage the aerosol delivery device, the device-side end defining a first passageway portion extending into the body, and the body defining a second passageway portion in fluid communication with the first passageway portion and extending from within the body to the container-side end; and
a valve located at the device-side end and configured to regulate the transfer of aerosol precursor composition from the container into the reservoir via the second passageway portion, the first passageway portion and the filling port, the valve including:
a valve body that is depressible, monolithic and defines a first valve member and a second valve member, the valve body and thereby the first valve member and the second valve member configured to depress when the device-side end is engaged with the aerosol delivery device, the first valve member configured to open the first passageway portion to enable the transfer of the aerosol precursor composition, and the second valve member configured to close the airflow port of the aerosol delivery device to prevent passage of the aerosol precursor composition through the airflow port.

2. The adapter of claim 1 , wherein a portion of the second valve member matches an inner cavity of the airflow port, the portion of the second valve member sized to be received within the inner cavity of the airflow port when the device-side end is engaged with the aerosol delivery device and the valve body is depressed.

3. The adapter of claim 1 , wherein the valve body is depressed by a protrusion of the aerosol delivery device within which the airflow port is defined, when the device-side end is engaged with the aerosol delivery device, and
wherein the device-side end includes a nozzle within which the valve is movably positioned, the nozzle defining a cavity sized to receive the second valve member when the device-side end is disengaged with the aerosol delivery device, and receive the protrusion of the aerosol delivery device when the device-side end is engaged with the aerosol delivery device and the valve body is depressed.

4. The adapter of claim 3 , wherein the nozzle includes a spout that is aligned with the first passageway portion and projects from a surface of the nozzle, and that is sized to be received within the filling port when the device-side end is engaged with the aerosol delivery device and the valve body is depressed.

5. The adapter of claim 4 , wherein the spout has a micro-patterned internal surface to promote the transfer of the aerosol precursor composition.

6. The adapter of claim 3 , wherein the nozzle further defines a tab within the cavity that is configured to mate with a matching slot defined on an outer surface of the protrusion of the aerosol delivery device, to align the device-side end with the aerosol delivery device when the device-side end is engaged with the aerosol delivery device.

7. The adapter of claim 1 , wherein the device-side end further defines an intermediary reservoir with a compressible body between the first passageway portion and the second passageway portion, the compressible body configured to receive aerosol precursor composition from the container via the second passageway portion, and force at least some of the aerosol precursor composition through the first passageway portion when compressed.

8. The adapter of claim 1 , wherein the container-side end is threaded and thereby threadable onto the container to connect the container-side end with the container.

9. The adapter of claim 1 , wherein the container-side end defines a sheath sized to receive at least a portion of the container inside the sheath to connect the container-side end with the container.

10. A method of mating a container of aerosol precursor composition with an aerosol delivery device having a reservoir that is refillable, the aerosol delivery device defining separate and distinct filling and airflow ports that are elongated passageways through which liquid or air is transportable, the method comprising:
connecting an adapter with the container, the adapter separate and distinct from the container and the aerosol delivery device, the adapter having a body having a container-side end and an opposing, device-side end, connecting the adapter with the container including connecting the container-side end with the container;
engaging the adapter with the aerosol delivery device, including engaging the device-side end with the aerosol delivery device, the device-side end defining a first passageway portion extending into the body and a second passageway portion in fluid communication with the first passageway portion and extending from within the body to the container-side end; and
transferring aerosol precursor composition from the container into the reservoir via the second passageway portion, the first passageway portion and the filling port, the adapter further including a valve located at the device-side end that regulates the transfer of aerosol precursor composition, the valve including a valve body that is depressible, monolithic and defines a first valve member and a second valve member,
wherein engaging the device-side end with the aerosol delivery device includes depressing the valve body and thereby the first valve member and the second valve member depressed, the first valve member opening the first passageway portion to enable the transfer of the aerosol precursor composition, and the second valve member closing the airflow port of the aerosol delivery device to prevent passage of the aerosol precursor composition through the airflow port.

11. The method of claim 10 , wherein a portion of the second valve member matches an inner cavity of the airflow port, and engaging the device-side end with the aerosol delivery device includes receiving the portion of the second valve member within the inner cavity of the airflow port when the valve body is depressed.

12. The method of claim 10 , wherein engaging the device-side end with the aerosol delivery device includes depressing the valve body by a protrusion of the aerosol delivery device within which the airflow port is defined, and
wherein the device-side end includes a nozzle within which the valve is movably positioned, the nozzle defining a cavity sized to receive the second valve member when the device-side end is disengaged with the aerosol delivery device, and engaging the device-side end with the aerosol delivery device also includes receiving the protrusion of the aerosol delivery device within the cavity when the valve body is depressed.

13. The method of claim 12 , wherein the nozzle includes a spout that is aligned with the first passageway and projects from a surface of the nozzle, and engaging the device-side end with the aerosol delivery device includes receiving the spout within the filling port when the valve body is depressed.

14. The method of claim 13 , wherein the spout has a micro-patterned internal surface to promote the transfer of the aerosol precursor composition.

15. The method of claim 12 , wherein the nozzle furthe
