Abstract

Some example embodiments include a reservoir assembly for an e-vaping device that may include a reservoir, a first bayonet connector assembly, and a conduit extending from a vaporizer assembly and into a space defined by the first bayonet connector assembly. The first bayonet connector assembly may detachably couple with a second bayonet connector assembly of an outlet assembly to establish a bayonet interface connection between the reservoir and the outlet assembly, such that the conduit is in fluid communication with the exterior of the reservoir assembly through an interior of the outlet assembly.

First claim

We claim:

1. A reservoir assembly for an e-vaping device, the reservoir assembly comprising:
a reservoir configured to hold pre-vapor formulation;
a first bayonet connector assembly at a first end of the reservoir, the first bayonet connector assembly including a base structure extending around an outer surface of an outer housing of the reservoir, such that the outer housing and the base structure at least partially define a partial enclosure; and
a conduit having a first end extending through the outer housing of the reservoir, out of the reservoir, and into the partial enclosure,
wherein the first bayonet connector assembly is configured to detachably couple with a second bayonet connector assembly of an outlet assembly to establish a bayonet interface connection between the reservoir and the outlet assembly, the outlet assembly having one or more inner surfaces that define an outlet assembly conduit extending through an interior of the outlet assembly between opposite, first and second openings, the outlet assembly conduit including a first conduit portion and a second conduit portion, the first conduit portion being proximate to the first opening of the outlet assembly and having a first diameter and a first length that are at least equal to a corresponding diameter and length, respectively of the first end of the conduit such that when the bayonet interface connection is established,
a portion of the outlet assembly is located within the partial enclosure between the first end of the conduit and the base structure of the first bayonet connector assembly and contacts the outer surface of the outer housing of the reservoir,
the first end of the conduit is inserted into and enclosed within the first conduit portion of the outlet assembly conduit via the first opening of the outlet assembly, and
the conduit is in fluid communication with an exterior of the reservoir assembly through the first end of the conduit and the outlet assembly conduit,

wherein the reservoir includes a fluid port that is separate from the conduit and extends through the outer housing of the reservoir to the outer surface of the outer housing at the first end of the reservoir, the fluid port configured to enable refilling of pre-vapor formulation in the reservoir via the fluid port,
wherein the first bayonet connector assembly is configured to cause the fluid port to be isolated from the exterior of the reservoir assembly by the outlet assembly based on the bayonet interface connection being established, such that
the fluid port is between the outlet assembly and the reservoir, and
the reservoir is isolated, by at least the outlet assembly, from fluid communication with the exterior of the reservoir assembly through the fluid port based on the portion of the outlet assembly being in the partial enclosure and contacting the outer surface of the outer housing of the reservoir.

2. The reservoir assembly of claim 1 , wherein
the conduit extends from a vaporizer assembly at a second end of the reservoir, wherein the first and second ends of the reservoir are opposite ends of the reservoir such that the first bayonet connector assembly and the vaporizer assembly are at opposite ends of the reservoir,
the vaporizer assembly is in fluid communication with the exterior of the reservoir assembly through the interior of the outlet assembly when the bayonet interface connection is established,
the fluid port is configured to enable refilling of pre-vapor formulation in the reservoir via the fluid port and independently of the vaporizer assembly, and
the first bayonet connector assembly is configured to cause the fluid port to be isolated from the exterior of the reservoir assembly by the outlet assembly based on the bayonet interface connection being established, such that
the reservoir is isolated, by at least the outlet assembly, from fluid communication with the exterior of the reservoir assembly independently of the vaporizer assembly.

3. The reservoir assembly of claim 1 , wherein the conduit extends through the partial enclosure.

4. The reservoir assembly of claim 1 , wherein the first bayonet connector assembly includes a bayonet plug connector element and is configured to detachably couple with a complementary bayonet receptacle connector element of the second bayonet connector assembly to establish the bayonet interface connection.

5. The reservoir assembly of claim 2 , further comprising:
a vaporizer connector assembly configured to detachably couple the reservoir with the vaporizer assembly.

6. The reservoir assembly of claim 5 , wherein an end of the conduit is coupled to the vaporizer connector assembly, such that the conduit is configured to couple with the vaporizer assembly via the vaporizer connector assembly.

7. The reservoir assembly of claim 1 , wherein the first bayonet connector assembly is directly coupled to the first end of the reservoir.

8. A vapor generator assembly for an e-vaping device, the vapor generator assembly comprising:
a reservoir and a vaporizer assembly, the reservoir configured to supply pre vapor formulation to the vaporizer assembly;
a first bayonet connector assembly at a first end of the reservoir, wherein the vaporizer assembly is at a second end of the reservoir, and the first and second ends of the reservoir are opposite ends of the reservoir such that the first bayonet connector assembly and the vaporizer assembly are at opposite ends of the reservoir, the first bayonet connector assembly including a base structure extending around an outer surface of an outer housing of the reservoir such that the outer housing and the base structure at least partially define a partial enclosure; and
a conduit having a first end extending from the vaporizer assembly, through the outer housing of the reservoir, out of the reservoir, and into the partial enclosure, the conduit configured to enable fluid communication between the vaporizer assembly and an exterior of the vapor generator assembly through the first bayonet connector assembly; and
an outlet assembly including a second bayonet connector assembly, the second bayonet connector assembly detachably coupled to the first bayonet connector assembly to establish a bayonet interface connection between the reservoir and the outlet assembly, the outlet assembly having one or more inner surfaces that define an outlet assembly conduit extending through an interior of the outlet assembly between opposite, first and second openings, the outlet assembly conduit including a first conduit portion and a second conduit portion, the first conduit portion being proximate to the first opening of the outlet assembly and having a first diameter and a first length that are at least equal to a corresponding diameter and length, respectively of the first end of the conduit such that when the bayonet interface connection is established,
a portion of the outlet assembly is located within the partial enclosure between the first end of the conduit and the base structure of the first bayonet connector assembly and contacts the outer surface of the outer housing of the reservoir,
the first end of the conduit is inserted into and enclosed within the first conduit portion of the outlet assembly conduit via the first opening of the outlet assembly,
the conduit is in fluid communication with the exterior of the vapor generator assembly through the first end of the conduit and the outlet assembly conduit, and
the vaporizer assembly is in fluid communication with the exterior of the vapor generator assembly through the conduit and the outlet assembly conduit,

wherein the reservoir includes a fluid port that is separate from the conduit and extends through the outer housing of the reservoir to the outer surface of the o
