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 reservoir refill system comprising:
a refill container containing a pre-vapor formulation, the refill container including,
a container body,
an opening in the container body,
a perforated disk having one or more holes therein, and
a spring-loaded disk; and

a reservoir configured to contain a pre-vapor formulation, the reservoir comprising:
a reservoir body configured to contain the pre-vapor formulation;
an opening in the reservoir body; and
a crown including one or more teeth thereon, the teeth sized and configured to be received in the one or more holes in the perforated disk, the crown configured to depress the spring-loaded disk so as to allow pre-vapor formulation to flow into the reservoir.

2. The reservoir refill system of claim 1 , further comprising:
a first interlocking ring including one or more of at least one groove and at least one protrusion therein at an opening in one of the container body and the reservoir body; and
a second interlocking ring including one or more of at least one groove and at least one protrusion therein at an opening of one of the container body and the reservoir body.

3. The reservoir refill system of claim 2 , wherein at least one of the first interlocking ring and the second interlocking ring is impregnated with at least one of a flavorant and a chemesthesis agent having one or more of a spicy, bitter, and sour taste.

4. The reservoir refill system of claim 3 , wherein at least one of the first interlocking ring and the second interlocking ring includes a coating comprising at least one of a flavorant and a chemesthesis agent having one or more of a spicy, bitter, and sour taste.

5. A refill container comprising:
a body containing a formulation;
an opening in the body; and
a first interlocking ring at the opening of the body, the first interlocking ring including at least one of a groove and a protrusion therein, the first interlocking ring configured to mate with a second interlocking ring attached to a reservoir configured to hold the formulation.

6. The refill container of claim 5 , further comprising:
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, the crown including a plurality of teeth, the teeth sized and configured to be received in perforations in a perforated disk so as to depress a spring-loaded disk.

7. The refill container of claim 5 , further comprising:
a cap integrally formed with the first interlocking ring.

8. A cartridge of an electronic vaping device, the cartridge comprising:
a housing extending in a longitudinal direction;
a chimney extending in the longitudinal direction, the chimney in the housing, the chimney including,
at least one protrusion along a length of the chimney, and
at least one stop along the length of the chimney;

a reservoir configured to contain a pre-vapor formulation, the reservoir being refillable, and the reservoir between the housing and the chimney; and
a valve circumscribing the chimney, the valve including,
a first ring abutting the at least one stop,
a second ring abutting the at least one protrusion, and
at least one pillar connecting the first ring and the second ring, the valve being formed of a flexible material.

9. The cartridge of claim 8 , wherein the at least one pillar is generally convex and the second ring has a larger diameter than the first ring.

10. The cartridge of claim 8 , wherein the flexible material is rubber.

11. The cartridge of claim 8 , wherein the at least one pillar is generally concave and the first ring has a larger diameter than the second ring.

12. A reservoir refill system comprising:
a refill container containing a pre-vapor formulation, the refill container including,
a container body,
an opening in the container body, and
a ball valve assembly positioned at the opening, the ball valve assembly including,
a ball valve portion,
a shoulder portion extending from the ball valve portion, the shoulder portion including one or more openings extending therethrough, and
a gasket portion integrally formed with the ball valve, the gasket portion connected to the ball valve by the shoulder portion; and

a cartridge configured to contain a pre-vapor formulation, the cartridge configured to mate with the refill container, the cartridge including,
a housing extending in a longitudinal direction;
a chimney extending in the longitudinal direction, the chimney in the housing, the chimney including,
at least one protrusion along a length of the chimney, and
at least one stop along the length of the chimney;

a reservoir configured to contain a pre-vapor formulation, the reservoir being refillable, and the reservoir between the housing and the chimney; and
a valve circumscribing the chimney, the valve including,
a first ring abutting the at least one stop,
a second ring abutting the at least one protrusion, and
at least one pillar connecting the first ring and the second ring, the valve being formed of a flexible material.

13. A refill container containing a pre-vapor formulation, the refill container comprising:
a container body;
an opening in the container body; and
a ball valve assembly positioned at the opening, the ball valve assembly including,
a ball valve portion,
a shoulder portion extending from the ball valve portion, the shoulder portion including one or more openings extending therethrough, and
a gasket portion integrally formed with the ball valve, the gasket portion connected to the ball valve by the shoulder portion.
