Abstract

A reservoir refill system for an electronic vaping device includes a refill container and a reservoir. The refill container contains a pre-vapor formulation. The refill container includes a body, an opening in the body, and a first interlocking ring including at least one groove or at least one protrusion therein. The reservoir is configured to contain a pre-vapor formulation and includes a reservoir body, an opening in the reservoir body, and a second interlocking ring including at least one groove or at least one protrusion therein at an opening of the reservoir. The first interlocking ring is configured to mate with the second interlocking ring so as to release the pre-vapor formulation from the refill container to the reservoir.

First claim

We claim:

1. A cartridge of an electronic vaping device, the cartridge comprising:
a reservoir configured to contain a pre-vapor formulation, the reservoir being refillable, and the reservoir including,
an opening, and
a first interlocking ring at the opening, the first interlocking ring including a plurality of grooves, a plurality of protrusions, or both a plurality of grooves and a plurality of protrusions spaced about a circumference of the first interlocking ring, the first interlocking ring configured to connect to a second interlocking ring attached to a refill container.

2. A cartridge of an electronic vaping device, the cartridge comprising:
a reservoir configured to contain a pre-vapor formulation, the reservoir being refillable, and the reservoir including,
an opening, the opening including,
a valve, the valve including a spring-loaded disk and a gasket, and

a first interlocking ring at the opening, the first interlocking ring including a groove, a protrusion, or both a groove and a protrusion, the first interlocking ring configured to connect to a second interlocking ring attached to a refill container.

3. The cartridge of claim 2 , wherein the spring-loaded disk is configured to be depressed so as to allow pre-vapor formulation to flow into the reservoir.

4. The cartridge of claim 2 , further comprising:
a chimney support configured to maintain the spring loaded disk in place until the first interlocking ring is connected to a second interlocking ring.

5. The cartridge of claim 2 , further comprising:
a perforated disk including at least one perforation therein, the at least one perforation sized and configured to receive at least one tooth, the at least one tooth configured to depress the spring-loaded disk.

6. An electronic vaping device comprising:
a housing extending in a longitudinal direction;
a reservoir configured to contain a pre-vapor formulation, the reservoir in the housing, the reservoir being refillable, and the reservoir including,
an opening, and
a first interlocking ring at the opening, the first interlocking ring including a plurality of grooves, a plurality of protrusions, or both a plurality of grooves and a plurality of protrusions spaced about a circumference of the first interlocking ring, the first interlocking ring configured to connect to a second interlocking ring attached to a refill container;

a heater in fluid communication with the reservoir; and
a power supply configured to supply power to the heater.

7. An electronic vaping device comprising:
a housing extending in a longitudinal direction
a reservoir configured to contain a pre-vapor formulation, the reservoir in the housing, the reservoir being refillable, and the reservoir including,
an opening, the opening including,
a valve, the valve including a spring loaded disk, a perforated disk, and a gasket, and

a first interlocking ring at the opening, the first interlocking ring including a groove, a protrusion, or both a groove and a protrusion, the first interlocking ring configured to connect to a second interlocking ring attached to a refill container;

a heater in fluid communication with the reservoir; and
a power supply configured to supply power to the heater.

8. The electronic vaping device of claim 7 , wherein the perforated disk includes at least one perforation therein, the at least one perforation sized and configured to receive at least one tooth, the at least one tooth configured to depress the spring-loaded disk so as to allow pre-vapor formulation to flow into the reservoir.

9. The electronic vaping device of claim 7 , further comprising:
a chimney support configured to maintain the spring loaded disk in place until the first interlocking ring is connected to a second interlocking ring.

10. A reservoir refill system comprising:
a reservoir configured to contain a pre-vapor formulation, the reservoir including,
a reservoir body configured to contain the pre-vapor formulation,
an opening in the reservoir body, and
a first interlocking ring including a first groove, a first protrusion, or both a first groove and a first protrusion therein, the first interlocking ring positioned at the opening in the reservoir body; and

a refill container containing a pre-vapor formulation, the refill container including,
a container body,
an opening in the container body, and
a second interlocking ring including a second groove, a second protrusion, or both a second groove and a second protrusion therein positioned at the opening in the container body, the first interlocking ring configured to mate with the second interlocking ring,

wherein the first groove, the second groove, of both the first groove and the second groove include a plurality of grooves,
the first protrusion, the second protrusion, or both the first protrusion and the second protrusion includes a plurality of protrusions,
the plurality of grooves and the plurality of protrusions are spaced about a circumference of the first interlocking ring, the second interlocking, or both the first interlocking ring and the second interlocking ring, and
the plurality of grooves are sized and configured to mate with the plurality of protrusions.

11. The reservoir refill system of claim 10 , wherein the first interlocking ring, the second interlocking ring, or both the first interlocking ring and the second interlocking ring are colored.

12. The reservoir refill system of claim 10 , wherein the first interlocking ring and the second interlocking ring are the same color.

13. The reservoir refill system of claim 10 , wherein the first interlocking ring, the second interlocking ring, or both the first interlocking ring and the second interlocking ring are formed of plastic.

14. The reservoir refill system of claim 10 , wherein the opening in the reservoir further includes a valve.

15. The reservoir refill system of claim 14 , wherein the valve includes a spring loaded disk, a perforated disk, and a gasket.

16. The reservoir refill system of claim 15 , wherein the perforated disk includes at least one perforation therein, the at least one perforation sized and configured to receive at least one tooth, the at least one tooth configured to depress the spring-loaded disk so as to allow pre-vapor formulation to flow into the reservoir.

17. The reservoir refill system of claim 15 , wherein the reservoir further comprises:
a chimney support configured to maintain the spring loaded disk in place until the first interlocking ring is connected to a second interlocking ring.

18. The reservoir refill system of claim 17 , wherein the refill container further comprises:
a ball valve in a neck of the opening, the ball valve including a spring-loaded ball; and
a crown adjacent the spring-loaded ball, the crown configured to shield the spring-loaded ball from being accessed.

19. The reservoir refill system of claim 10 , wherein the first interlocking ring, the second interlocking ring, or both the first interlocking ring and the second interlocking ring are impregnated with a flavorant, a chemesthesis agent, or both the flavorant and the chemesthesis agent having a spicy taste, a bitter taste, a sour taste, a sub-combination thereof, or a combination thereof.

20. The reservoir refill system of claim 10 , wherein the first interlocking ring, the second interlocking ring, or both the first interlocking ring and the second interlocking ring includes a coating comprising a flavorant, a chemesthesis agent, or both the flavorant and the chem
