Description
INDEX TO RELATED APPLICATIONS
[0001] This application is a non-provisional of and claims benefit
to U.S. Provisional Patent Application Ser. No. 61/951,888 filed
Mar. 12, 2015 the disclosure of which is incorporated herein by
reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] Electronic cigarettes (e-cigs) have become a popular
alternative to conventional cigarettes. Although there are many
touted advantages, current electronic cigarettes still include
various aspects in their configurations that are not optimal.
[0003] With the increased popularity of e-cigarettes, configuration
flaws have raised several issues.
[0004] The list below includes but is not limited to, several known
issues with current e-cigarette cartridges: [0005] 1. The current
cartridges can leak e-liquid, which causes a problem for shelf life
and overall product quality. [0006] 2. The wadding used for
transferring the e-liquid to the wick varies in volume causing
different burn rates. [0007] 3. The heater cartridge assemblies are
filled by hand using a syringe, which allows for various volumes to
be in the cartridges.
SUMMARY OF THE INVENTION
[0008] In one embodiment, the current invention is an electronic
cigarette system comprising:
[0009] an outer cartridge assembly;
[0010] an inner housing configured to hold a liquid;
[0011] a mouthpiece configured as a unitary single piece being part
of said inner housing;
[0012] a heater;
[0013] a power source; and
[0014] an actuator operatively associated with said power source,
said heater configured to vaporize liquid in said inner housing and
deliver said vapor through the mouthpiece.
[0015] In a preferred embodiment, the fluid cylinder has 2 flat
sides to it. This is to allow the vapor to travel up to the end. At
the end, there is a cut out channel that has a hole in it. This is
where the vapor exits.
[0016] In one embodiment, there is a Polyethylene terephthalate
(PET) pad. This PAD is heat staked to the cartridge. The fluid
soaks this pad but it doesn't leak. The wick then touches this PET
pad and through a capillary action and also gets wet. The heater
then vaporizes the fluid off of the wick.
[0017] In one preferred embodiment, the interior of the cylinder
tapers. This is needed to release the cylinder from the mold during
manufacture. The same is true on the exterior of the cartridge.
This is referred to as an angular offset.
[0018] Where the vapor leaves the cartridge, this is all a single
piece. This is achieved with slides in the mold. Because of this,
it is all a single material and a single piece.
[0019] In one embodiment, the invention is an electronic cigarette
system comprising:
[0020] an outer cartridge assembly;
[0021] an inner housing configured to hold a liquid, said inner
housing formed with a pair of opposing flat sides on either side of
a circular cylinder, whereby each flat side angles inward in an
angular offset towards a central axis of said inner housing;
[0022] a mouthpiece configured as a unitary single piece being part
of said inner housing;
[0023] a heater;
[0024] a power source; and
[0025] an actuator operatively associated with said power source,
said heater configured to vaporize liquid in said inner housing and
deliver said vapor through the mouthpiece.
[0026] In one embodiment, the mouthpiece is fused to said inner
housing in a manner free of adhesive. Adhesive attachment is
disfavored due to continual use of vaporized liquid could cause
adhesive to be releases and ingested.
[0027] In one embodiment, the angular offset is 0.5-2.0 degrees
inward towards said central axis relative to a perpendicular
line.
[0028] In one embodiment, the angular offset is 0.5 degrees inward
towards said central axis relative to a perpendicular line.
[0029] In one embodiment, the system is including a polyethylene
terephthalate pad that is heat staked to the inner housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0041] The present invention overcomes the problems known in the
art by providing an assembly having a heater assembly 10, outer
cartridge housing 12 and inner (liquid) cartridge assembly 14. The
inner assembly 14 is configured with an inner assembly inner
housing, 16, and a screen 18. Although many materials are suitable
to form screen 18, preferred material include, but are not limited
to felt or metal.
[0042] The configurations disclosed herein represent a significant
improvement in manufacturing and use by providing a mouthpiece or
vapor outlet formed as a single unitary structure with the inner
assembly.
[0043] Currently used adhesives utilized in affixing mouthpieces
are subject to failure and present significant danger to users.
[0044] The present configuration not only provides for the unitary
structure, but provides a unitary structure configured for filling
with a vaporizable liquid after the structure is fully
assembled.
[0045] The inner housing, 16 provides an incorporated mouth piece
portion 26 from which the user will inhale the vapor. Prior
e-cigarettes required the mouthpiece to be a second member formed
and attached to the assembly. The liquid cartridge assembly, 14, is
filled through the felt or metal screen, 18, using a hyperemic
filling needle, or similar device.
[0046] In one embodiment, the present invention includes a heater
assembly 20, outer cartridge housing, 22, and inner (liquid)
cartridge assembly, 24, which is has a septum style mouthpiece, 26,
inner housing, 28, and felt or metal screen, 30.
[0047] In an embodiment as best shown in FIG. 4, components are
aligned and the assembly including mouthpiece 26 inner housing 28
are fused to result in a single piece that requires no adhesive. In
one embodiment, the single fused structure is assembled with a
sonic weld as is known in the art.
[0048] The liquid cartridge, 14, is then inserted into the outer
cartridge, 12, and fully seats on top of the heating element, 10,
to allow e-liquid to be transferred to the heater assembly.
[0049] The inner housing, 16, has an inner central cavity 19.
Housing 16 is semi rigid plastic in the preferred embodiment. In
the secondary embodiment, the inner housing, 16, is soft plastic
that will provide the user a softer more realistic conventional
cigarette feel.
[0050] In one embodiment, inner assembly housing 16 is not a round
cylinder but includes a pair of opposite congruent flat sides as
seen in FIG. 10. Perimeter portion 50 has flat side 52 formed
therewith. Mouthpiece end 40 has vapor exit 42 formed thereon and
is formed adjacent to channel 21.
[0051] These sides are not perpendicular to the base, but include
an angular offset.
[0052] As best seen in FIG. 11. A theoretical flat base line 60 is
formed with the base of the device of the present invention. As
understood, the base is the end where channel 21 and mouthpiece 40
are positioned. There is a centerline 62 that is the center of
assembly 16. Lines 64 represent perpendicular lines relative to
base line 60. Offset lines 66 represent the direction and
orientation of flat sides 52. Angle 68 represents the angular
offset inward towards centerline 62 of each flat side 52. Angle 68
is between 0.5-2.5 degrees offset inward from perpendicular lines
64. In one preferred embodiment, the angular offset is 0.5 degrees.
It has been discovered that angles greater than 2.5 degree offset
are disfavored and lead to numerous manufacturing and use
difficulties.
[0053] If has been discovered that the slight angular offsets
disclosed herein represents a significant improvement in providing
greater precision and accuracy in manufacturing on a commercial
level.
[0054] While the invention has been described in its preferred form
or embodiment with some degree of particularity, it is understood
that this description has been given only by way of example and
that numerous changes in the details of construction, fabrication,
and use, including the combination and arrangement of parts, may be
made without departing from the spirit and scope of the
invention.
