APPARATUS COMPRISING A CHECK VALVE FOR DISPENSING E-LIQUIDS
An apparatus comprising a check valve may be utilized to transfer E-liquid from a storage container into an electronic vaporization device, such that unintended leakage of the E-liquid may not occur. An apparatus comprising a check valve, wherein the apparatus is pre-loaded with E-liquid, may be used to dispense liquid into an electronic vaporization device.
This application claims priority to U.S. Provisional Patent Application No. 61/976,225, entitled “Apparatus Comprising A Check Valve for Dispensing E-Liquids,” filed on Apr. 7, 2014, the disclosure of which is incorporated by reference herein.
TECHNICAL FIELDThe disclosure is directed to an apparatus comprising a check valve. The apparatus may be utilized to transfer E-liquid into the chamber of an electronic vaporization device, such that unintended leakage and/or spillage of the E-liquid may not occur. The apparatus may be used to transfer E-liquid into a top-filled chamber or a bottom-filled chamber. The disclosure is further directed to an assembly of an apparatus comprising a check valve and an E-liquid storage container. The assembly allows the E-liquid to be stored without accidental dispensing and/or spilling of the E-liquid.
BACKGROUNDVaporization provides an alternative to combustion for the delivery and consumption of various substances. Typically the substance to be vaporized is present in a liquid, which is commonly referred to as an “E-liquid.” Examples of substances to be vaporized that are present in an E-liquid are selected from the group of: glycerin, propylene glycol, flavorings, nicotine, medicaments and combinations thereof. Vaporization may be accomplished using electronic vaporization devices, including, but not limited to, electronic cigarettes, electronic cigars, electronic pipes and electronic vaporizers.
Oftentimes, the E-liquid to be vaporized is placed into a chamber, which either contains, or interfaces with, a heat source in the electronic vaporization device. The chamber which contains the E-liquid may take a variety of forms, depending upon the configuration of the electronic vaporization device. Some chambers are referred to in the art as “cartomizers.” Cartomizers that are see-through, i.e. made of plastic or glass for example, are oftentimes referred to as “clearomizers.” Typically, cartomizers and clearomizers contain a heating source, such as an atomizer. The cartomizer or clearomizer may further comprise absorbent material with or without an associated wick that act(s) to transport E-liquid to the heating source that vaporizes E-liquid. The cartomizer or clearomizer may further comprise a vapor chimney through which the resulting E-liquid vapor passes to be delivered to the consumer, such as via a mouthpiece.
Once an E-liquid is consumed, the chamber may be discarded and replaced with a new, full chamber. However, some chambers are re-fillable. A consumer may refill a chamber with E-liquid by opening the chamber and using for example, a dropper or syringe, to dispense the E-liquid into the chamber. This process may be characterized by several disadvantages. First, if during the filling process, E-liquid is errantly dispensed into the vapor chimney, the heating source may be compromised and/or leakage from the chamber may occur. For example, if the heating source is an atomizer, the atomizer may become clogged by the E-liquid, resulting in the malfunction of the electronic vaporization device. Second, and perhaps more importantly, transferring the E-liquid from its storage bottle to the cartomizer may result in spillage of the E-liquid. In addition to being messy, spillage of the E-liquid may be particularly disadvantageous if the E-liquid contains a substance, nicotine for example, which ideally should not be in direct contact with the skin of a human or animal.
For these and other reasons, there remains a need for an apparatus for dispensing E-liquids into the chamber of an electronic vaporization device that minimizes, if not eliminates, the spillage and/or leaking of an E-liquid when it is being transferred into the chamber. Additionally, there remains a need for such an apparatus that will prevent E-liquid from errantly being dispensed into the vapor chimney of the chamber. Moreover, there remains a need for an apparatus that will minimize, if not eliminate, a human's (e.g., a consumer's, or a child's) or an animal's (e.g. a pet's) contact with the E-liquid during E-liquid storage and/or dispensing. Moreover, it would be advantageous if such an apparatus could be used to dispense E-liquid into either a top-filled or bottom-filled chamber.
SUMMARYThe unique solution that addresses the aforementioned need is a new apparatus comprising a check valve. The apparatus minimizes, if not eliminates, the leakage and/or spillage of an E-liquid when it is being dispensed into the chamber of an electronic vaporization device, regardless of whether the chamber is configured to be filled through its top or bottom. The apparatus according to the present disclosure may accomplish this, at least in part, by precisely aligning the opening of an E-liquid storage bottle, with the opening in the cartomizer into which the E-liquid is to be dispensed. Additionally or alternatively, the apparatus may physically block the vapor chimney in the chamber. By blocking the vapor chimney, the apparatus may prevent misdirection of the E-liquid and in turn, prevent subsequent leakage of the E-liquid from the chamber, and consequent exposure of the consumer, to the E-liquid. Additionally, or alternatively, the apparatus may be engaged with an E-liquid storage container to form an assembly such that E-liquid is prevented from accidentally spilling from the container; in some embodiments, the assembly may be sold as a unit. Such an assembly may also prevent leakage and/or contamination of the outside of the E-liquid storage container, and consequent exposure of anyone, e.g. a human or pet, which comes into contact with the E-liquid storage container.
The terms “chamber,” “liquid chamber,” “tank,” “liquidmizer,” “cartomizer” and “clearomizer,” are used interchangeably herein to mean a reservoir that contains an E-liquid to be vaporized by an electronic vaporization device. A chamber may or may not contain the heat source, e.g. an atomizer, which is utilized to vaporize the E-liquid. A chamber may be filled with E-liquid through its open top, i.e., be a “top-filled chamber,” or it may be filled with E-liquid through its open bottom, i.e., a “bottom-filled chamber.”
“Check valve” as used herein means a valve that allows E-liquid to flow through it in only one direction.
“Electronic vaporization device,” hereinafter “EVD,” as used herein means any electronic device which vaporizes liquid for consumption including, but not limited to, via inhalation, by a consumer. EVDs include, but are not limited to: electronic cigarettes; electronic cigars; and electronic vaporizers.
“B-liquid storage container,” “B-liquid container,” “storage container,” “B-liquid bottle,” “storage bottle,” and “container” are used interchangeably herein to mean a vessel that contains E-liquid.
The elements or features of the various embodiments are described in detail hereinafter. Any reference to a singular characteristic or limitation of the present disclosure shall include the corresponding plural characteristics or limitations, and vice versa, unless otherwise specified or clearly implied to the contrary by the context in which the reference is made.
The apparatuses and methods described herein may comprise, consist of, or consist essentially of the elements and features of the disclosure described herein, as well as any additional or optional components, or features described herein or otherwise useful in relation to the aforementioned apparatuses and methods.
All documents (patents, patent applications and other publications) cited in this application are incorporated herein by reference in their entirety.

In spite of the presence of narrow gaps and/or small openings through which E-liquid is dispensed, the apparatus according to the present disclosure may eliminate the aforementioned problems regardless of whether the chamber is top-filled or bottom-filled.
In general, the base of the apparatus comprises at least one liquid passageway and/or hole through which E-liquid may travel into the apparatus from an E-liquid storage container that is attached thereto as described below. The liquid passageway and/or holes may be formed in any suitable way using structural means so long as adequate flow of E-liquid from the E-liquid storage container into the apparatus is achieved. Useful structural means may be selected from the group of: o-rings; ports; metal rings; rubber rings; silicone rings; and combinations thereof. In some embodiments, the liquid passageway and/or holes provide only for one-way flow, meaning that E-liquid may flow from the E-liquid storage container through the liquid passageway and/or holes into the apparatus, but E-liquid may not flow out of the apparatus through the liquid passageway and/or holes. This one-way feature prevents leakage of the E-liquid from the apparatus, which is a particularly desirable feature after the apparatus has been detached from the E-liquid storage container, and is stored until its next use.

The top of the apparatus housing may comprise an engagement means for being connected to either the top or the bottom of a chamber into which E-liquid is to be dispensed. Any suitable engagement means may be used to removeably connect the top of the housing to the chamber to be filled so long as the engagement means provides for a seal between the top of the housing and the chamber. Useful engagement means are selected from the group of: slots; silicone seals; and combinations thereof In the embodiment shown in
The check valve shown in
Generally, when in use, the base of the apparatus may be engaged with an E-liquid storage container using attachment means that prevent leakage of the E-liquid from the attachment point. Useful attachment means may be selected from the group of: welds, e.g., ultrasonic welds; threads; magnetic connectors; flanges and combinations thereof.
In use, the top of the apparatus may be engaged with a chamber into which E-liquid is to be dispensed as follows. The top of the apparatus is aligned and sealably connected with the open top of a top-filled chamber, or the open bottom of a bottom-filled chamber; this may be accomplished using any suitable means, including, but not limited to by being: screwed together via threaded connections; magnetically coupled; pressure fitted together; and combinations thereof.
The same apparatus 100 may likewise be used to dispense E-liquid into a bottom-filled chamber. Referencing
E-liquid may be dispensed into the clearomizer several ways. First, an apparatus 100 that has been attached at its base to an E-liquid container 400 (for example, as shown in FIG. 6) may then be joined at its top to the chamber 200 to be filled (for example, as shown in

E-liquid may then be dispensed into the cartomizer 520 as follows. When the biasing force of the spring 2 against the closing member 6 is overcome by a force exerted by a consumer squeezing the storage bottle 400 containing the E-liquid, the closing member 6 is unseated and the opening 60 is unsealed. E-Liquid 300 is then free to pass into the chamber 200, after which it is gravity fed and/or pushed by squeezing the bottle through the apparatus and into the chamber to be filled. By virtue of the vapor chimney 231 pressing against the closing member 6, the vapor chimney 231 is sealed off so that no E-liquid 300 may pass into the vapor chimney 231 and potentially contaminate the heat source, in this embodiment, an atomizer (not shown).
The same apparatus 100 may likewise be used to dispense E-liquid into a bottom-filled chamber. Referencing
Once the desired amount of E-liquid 300 is dispensed into the chamber 200, the force exerted by squeezing the storage bottle 400 is removed, such as by the consumer relaxing his or her grip on the storage bottle 400. Removal of this force allows the biasing force of the spring 2 to force the closing member 6 back into the opening 60. Once the closing member 6 is re-seated in the opening 60, the apparatus 100 is re-sealed, and no E-liquid 300 remaining therein may escape. Generally, E-liquid is prevented from escaping from the fluid passageways 7 in the top 8 of the apparatus 100 by capillary action acting on the viscous E-liquid and by the exertion of negative pressure on the E-liquid in the fluid passageways 7 resulting from the consumer relaxing his or her grip on the storage bottle 400. Moreover, no E-liquid 300 may flow from the storage bottle 400 into the apparatus 100. Likewise, no E-liquid 300 may accidentally leak or spill from the storage bottle 400.
Once the apparatus 100 and the chamber 200 are disengaged, the chamber 200 may be re-sealed such as by screwing the mouthpiece (not shown) of the chamber 200 back into place. The apparatus 100 may be retained in an engaged position with the E-liquid storage bottle 400 until such time as the storage bottle 400 is emptied of its E-liquid 300 contents. Should the bottle 400 accidentally be squeezed while the apparatus 100 and storage bottle 400 are engaged, no leakage of the E-liquid 300 outside of the storage bottle 400 may occur, thus preventing any unwanted contact with the E-liquid 300.
EVDs 500 that are currently on the market vary in shape and size. In order for the apparatus 100 to be used with a wide variety of EVDs 500, the apparatus may further comprise one or more adapters 600. The adapter 600 may be integral to the apparatus 100 or may be attached thereto as needed. For example, a relatively short adapter 600 may be useful for connecting the apparatus 100 to a chamber 200 having a relatively tall vapor chimney 231 so that the vapor chimney 231 is effectively sealed off by the closing member 16 during E-liquid dispensing as discussed above. Likewise, a relatively longer adapter 600 may be useful for connecting the apparatus 100 to a chamber 200 having a relatively short vapor chimney 231. In a further example, the apparatus 100 may have a smaller or larger width or diameter than the top of the chamber 200, and as such, an adapter would enable the apparatus 100 to be inserted into or around a chamber 200 that it would not otherwise fit. By utilizing an adapter 600 that is universal or a set of adapters 600 having different sizes, in conjunction with the apparatus 100, a variety of chambers 200, such as chambers 200 made by different manufacturers, may be filled using a single apparatus 100.
