Description
- The present invention relates to liquid dispensers for refilling liquid containing vessels and methods for refilling liquid concentrator systems having a portable portion that can be connected and disconnected with respect to a base portion.
- An electronic cigarette is a hand-held, easily transportable device that vaporizes a liquid solution for inhalation by a user. Electronic cigarettes are also sometimes referred to by the names e-cigarette and personal vaporizer. The liquid solution typically includes a flavoring. Because electronic cigarettes are often used as a replacement for conventional cigarettes, the liquid solution also typically includes nicotine.
- Because the liquid solution is vaporized during use, it is eventually depleted. Refilling an electronic cigarette can be a cumbersome and time consuming process. As an example, many electronic cigarettes include a wicking material in which the liquid solution is stored until it is vaporized. One common method for refilling this type of electronic cigarette utilizes a dropper to drip the solution on to the wicking material. Because the wicking material is typically located within a narrow housing, using a dropper to apply the liquid solution to the wicking material can be difficult and messy. Another common method for refilling this type of electronic cigarette utilizes a syringe to apply the liquid solution to the wicking material. While this solves some of the problems associated with using a dropper, many persons are uncomfortable with the idea of possessing and using a syringe, which limits mass-market acceptance of this method.
- Liquid dispensers and methods for refilling liquid containing vessels are taught herein.
- One aspect of the disclosed embodiments is a method that includes providing a container having a liquid disposed therein; providing a cap having a first portion that defines a bore and a second portion that is connectable to the container; connecting the second portion of the cap to the container such that the liquid is in communication with the cap; connecting the first portion of the cap to a liquid reservoir for an electronic cigarette such that the first portion of the cap is substantially sealed with respect to the liquid reservoir of the electronic cigarette; and causing the liquid to flow from the container and into the liquid reservoir of the electronic cigarette.
- Another aspect of the disclosed embodiments is a method for filling a liquid reservoir for an electronic cigarette, the liquid reservoir including a tubular housing that extends from a first end to a second end, and a connecting structure located at the first end of the tubular housing, the connecting structure including an aperture that extends through the connecting structure for communication with an interior of the tubular housing. The method includes providing a container having a liquid disposed therein; providing a cap having a second portion that is connectable to the container, a first portion that defines a bore, and a nozzle that extends through the bore of the first portion, the nozzle having an interior and a liquid dispensing tip; connecting the second portion of the cap to the container such that the liquid is in communication with the interior of the nozzle; connecting the first portion of the cap to the connecting structure of the liquid reservoir such that the nozzle of the cap is at least partially disposed within the aperture of the connecting structure; and causing the liquid to flow from the container, through the nozzle, and into to the tubular housing.
- Another aspect of the disclosed embodiments is an apparatus that includes a liquid dispensing cap. The liquid dispensing cap has a first portion that is substantially tubular and has an inner annular wall that defines a bore that extends through the first portion. The liquid dispensing cap also has a nozzle that is disposed at least partially within the bore of the first portion. The nozzle has a liquid dispensing opening and an outer surface, wherein the outer surface of the nozzle is spaced apart from the inner annular wall of the first portion.

Furthermore, when thecontainer 110 is connected to thecap 120, thecontainer 110 engages thenozzle 150 and captures thenozzle 150 between thecontainer 110 and thecap body 122, such that thenozzle 150 is restrained against moving with respect to the cap body 122 (FIG. 5A ). -
FIG. 5A is a cross-section view of theliquid dispenser 100 and first example of aliquid reservoir 200 for an electronic cigarette (not shown) wherein theliquid dispenser 100 is in a disconnected position relative to theliquid reservoir 200 for the electronic cigarette.FIG. 5B is a cross-section view of theliquid dispenser 100 and theliquid reservoir 200 for the electronic cigarette wherein theliquid dispenser 100 is in a connected position relative to theliquid reservoir 200 for the electronic cigarette. - The
liquid reservoir 200 includes atubular housing 210 that extends from afirst end 212 to asecond end 214. The tubular housing can be formed from materials such as metal or plastic. A connectingstructure 220 is located at thefirst end 212 of thetubular housing 210. Amouthpiece 250 can be located at thesecond end 214 of thetubular housing 210. - The connecting
structure 220 includes anaperture 222 that extends through the connectingstructure 220 for communication with an interior of thetubular housing 210. The connectingstructure 220 can also include ascrew thread 224 that is formed on the connectingstructure 220. In particular, the connectingstructure 220 can be substantially cylindrical, and thescrew thread 224 can be formed on the outer annular surface or wall of the connectingstructure 220. - The
mouthpiece 250 is connected to thetubular housing 210 and has apassageway 252 formed therethrough. Thepassageway 252 allows fluid communication between the interior of thetubular housing 210 and the exterior of thetubular housing 210, such that air can be drawn through thetubular housing 210 by the user, thus allowing delivery of the vaporized liquid to the user. - In the illustrated example, the
mouthpiece 250 is in the form of a plug that as formed from a resilient plastic or rubber and is connected to thetubular housing 210 by a friction fit. Mouthpieces can be provided in other forms, such as being integrally formed with respect to thetubular housing 210 or such as in the form of an elongated body that is connected to thesecond end 214 of thetubular housing 210 and extends outward therefrom. - The
liquid reservoir 200 includes awicking material 230 that is disposed within thetubular housing 210. The wickingmaterial 230 is adapted to absorb and store a liquid, such as a liquid solution that includes a flavoring and/or nicotine. The wickingmaterial 230 can be a substantially cylindrical body of any suitable absorbent material. Apassageway 232 can be formed axially through the wickingmaterial 230. The wickingmaterial 230 stores the liquid for use by avaporizer assembly 240. As an example, thevaporizer assembly 240 can include a wicking tube that receives liquid from the wickingmaterial 230 and an electric heating coil that receives power from a battery associated with the electronic cigarette via the connectingstructure 220, where the electric heating coils heats the fluid in order to vaporize it. Other types of vaporizer assemblies can be provided as thevaporizer assembly 240. - The
liquid dispenser 100 can be moved from the disconnected position (FIG. 5A ) with respect to theliquid reservoir 200 to the connected position (FIG. 5B ) with respect to theliquid reservoir 200. The disconnected position is established when theliquid dispenser 100 is not engaged with theliquid reservoir 200. The connected position is established when thefirst portion 124 of thecap 120 of theliquid dispenser 100 is engaged with theliquid reservoir 200 such that thefirst portion 124 of thecap 120 is substantially sealed with respect to theliquid reservoir 200. A substantially seal is defined as a seal that is not necessarily an air-tight or fluid-tight seal, but is sufficient to allow transfer of liquid from theliquid dispenser 100 to theliquid reservoir 200 with minimal leakage. - As an example, a substantial seal can be defined in the connected position by threaded engagement of the
screw thread 134 of thefirst portion 124 of thecap 120 of theliquid dispenser 100 with thescrew thread 224 of the connectingstructure 220 of theliquid reservoir 200. As another example, thescrew thread 134 of thefirst portion 124 of thecap 120 and thescrew thread 224 of the connectingstructure 220 of theliquid reservoir 200 can be omitted, and instead, a friction fit can establish a substantial seal between thescrew thread 134 of thefirst portion 124 of thecap 120 and thescrew thread 224 of the connectingstructure 220 of theliquid reservoir 200. In this example, one or both of thefirst portion 124 of thecap 120 or the connectingstructure 220 of theliquid reservoir 200 could be formed from a resilient material such as soft plastic, rubber, or silicone to promote a substantial seal. As another example, one of thescrew thread 134 of thefirst portion 124 of thecap 120 or thescrew thread 224 of the connectingstructure 220 of theliquid reservoir 200 can be omitted, and engagement of thefirst portion 124 of thecap 120 with the connectingstructure 220 of theliquid reservoir 200 could cause cutting of the omitted screw thread by the other screw thread. - In use, the
liquid reservoir 200 can be filled using a liquid that is disposed within thecontainer 110 of theliquid dispenser 100. Thefirst portion 124 of thecap body 122 of thecap 120 of theliquid dispenser 100 is connected to the connectingstructure 220 of theliquid reservoir 200 such that thenozzle 150 of the cap is at least partially disposed within theaperture 222 of the connectingstructure 220. A substantial seal can thus be defined between thefirst portion 124 of thecap body 122 of thecap 120 and the connectingstructure 220 of theliquid reservoir 200. The user then causes the liquid to flow from thecontainer 110, through thenozzle 150, and into to thetubular housing 210, for example, by applying pressure to thecontainer 110. This causes the fluid to contact thewicking material 230, so that thewicking material 230 can absorb at least a portion of the liquid and store the liquid for later use. Causing the liquid to flow from thecontainer 110, through thenozzle 150, and into to thetubular housing 210 can include applying pressure to the liquid. One example of application of pressure to the liquid includes compressing the internal space of thecontainer 110, such as by squeezing thecontainer 110. As the liquid enters thetubular housing 210, it initially travels through thepassageway 232 that is defined through the wickingmaterial 230. Forcing the liquid into thewicking material 230 can be performed by blocking fluid conducting pathways along which the fluid could otherwise exit thetubular housing 210 prior to causing the liquid to flow from thecontainer 110, through thenozzle 150, and into to thetubular housing 210. As an example, blocking fluid conducting passageways can include sealing thesecond end 214 of thetubular housing 210. As another example, blocking fluid conducting passageways can include blocking thepassageway 252 of themouthpiece 250. As an example, the user can block thepassageway 252 by engaging an object with themouth piece 250 at thepassageway 252, such as afinger 10 of the user. In some examples, doing this can include sealing thesecond end 214 of thetubular housing 210. - In the foregoing example, the
liquid dispenser 100 includes thenozzle 150. However, in some implementations, the nozzle is omitted. Use of theliquid dispenser 100 without thenozzle 150 remains the same, except that the liquid passes through thecap body 122 directly , instead of passing through the nozzle. -
