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,
an opening in the container, and
a ball valve assembly at the opening, the ball valve assembly including,
a ball valve portion, and
a valve support 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 stop along a length of the chimney, and
at least one protrusion along the length of the chimney,

a reservoir configured to contain a pre-vapor formulation, the reservoir being refillable, and
a valve at least partially 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.

2 . The reservoir refill system of claim 1 , wherein the valve support portion comprises:
a shoulder portion extending from the ball valve portion, and a gasket portion connected to the ball valve by the shoulder portion.

3 . The reservoir refill system of claim 2 , wherein the valve support portion is integrally formed with the ball valve portion.

4 . The reservoir refill system of claim 1 , wherein the valve of the cartridge is formed of a flexible material.

5 . The reservoir refill system of claim 1 , wherein the ball valve assembly is formed of a flexible material.

6 . The reservoir refill system of claim 5 , wherein the flexible material comprises rubber or plastic.

7 . The reservoir refill system of claim 1 , wherein the container includes a refill bottle.

8 . The reservoir refill system of claim 1 , wherein the container includes a tube.

9 . The reservoir refill system of claim 1 , wherein the container further includes a neck portion, the ball valve portion in the neck portion.

10 . The reservoir refill system of claim 1 , wherein the ball valve assembly is resilient.

11 . A refill container containing a pre-vapor formulation, the refill container comprising:
a container; an opening in the container; and a ball valve assembly at the opening, the ball valve assembly including,
a ball valve portion, and
a valve support portion.

12 . The refill container of claim 11 , wherein the valve support portion comprises:
a shoulder portion extending from the ball valve portion, the shoulder portion including one or more openings extending therethrough.

13 . The refill container of claim 12 , wherein the valve support portion further comprises:
a gasket portion is connected to the ball valve portion by the shoulder portion.

14 . The refill container of claim 13 , wherein the gasket portion is integrally formed with the ball valve portion.

15 . The refill container of claim 11 , wherein the ball valve assembly is formed of a flexible material.

16 . The refill container of claim 15 , wherein the flexible material comprises rubber or plastic.

17 . The refill container of claim 15 , wherein the container includes a refill bottle.

18 . The refill container of claim 15 , wherein the container includes a tube.

19 . The refill container of claim 15 , wherein the container further includes a neck portion, the ball valve portion in the neck portion.

20 . The refill container of claim 15 , wherein the ball valve assembly is resilient.
