Description

PRIORITY

This non-provisional application claims priority to Provisional U.S. Patent Application Ser. No. 61/853,048 filed Mar. 27, 2013.

BACKGROUND

In many instances, a person, trying to remove the last vestiges of a viscous liquid from a fluid-containing bottle, experiences only frustration for his or her efforts. When this scenario is repeated again and again by a large number of consumers, a big waste of money and resources can result. There is a need for a low cost device which one can easily use to empty the entire contents of the bottle.
Thus, there is a need for a device with which one can transfer virtually 100 percent of the residual contents of a fluid-containing bottle from it to another bottle so that the residual fluid can be collected in the latter vessel and stored therein for subsequent consumption at the user's convenience. Moreover, there is a need for a device that may quickly and easily couple to one or more bottles to facilitate transfer of fluid between the bottles.

SUMMARY

In one exemplary embodiment, a device for transferring fluid may be provided. The transferring device may include a first cap member having a first internal thread and a first channel extending through the first cap member, and a second cap member having a second internal thread and a second channel extending through the second cap member. The first cap member and the second cap member may be coupled to one another, and the first channel may be fluidly connected with the second channel.
In another exemplary embodiment, a system for transferring fluid from a first bottle to a second bottle may be provided. The system may include a first cap member having a first internal thread and a first channel extending through the first cap member, and a second cap member having a second internal thread and a second channel extending through the second cap member. The system may further include a first bottle having a first interior chamber and a second bottle having a second interior chamber. The first cap member and the second cap member may be coupled to one another, and the first channel may be fluidly connected with the second channel.

DETAILED DESCRIPTION

Aspects of the present invention are disclosed in the following description and related figures directed to specific embodiments of the invention. Those skilled in the art will recognize that alternate embodiments may be devised without departing from the spirit or the scope of the claims. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention.
As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiments are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention”, “embodiments” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.
Exemplary FIGS. 1 and 2 depict an exemplary transfer device that is indicated generally by the reference numeral 10.
The transfer device 10 may have a structure that defines a pair of oppositely directed, screw thread sets that are aligned axially and between which a through channel 13 may extend longitudinally along the respective axis of each such set. Further, each individual screw thread set may be sized and threaded to threadedly engage a bottle 1, 2.
These screw thread sets may be provided by two screw-on caps 11 and 12 which may be welded, glued, or otherwise coupled together. The transfer device 10 may alternatively be formed integrally as a single, unitary piece fabricated of plastic or the like. Each of the caps 11, 12 may have a cylindrical body having an interior surface upon which the respective thread set is disposed. Each of the caps 11, 12 may further comprise an opening configured to receive a portion of a bottle at one end of the cylindrical body, and a top portion disposed at the opposite end of the cylindrical body. The first and second caps 11, 12 may be coupled or formed integrally together such that the top portion of the first cap 11 is directly affixed to the top portion of the second cap 12. A bore through the interface between the caps 11, 12 so affixed may complete the through channel 13, so that gravity can be used to transfer fluid from an inverted bottle 2 into an upright bottle 1.
Prior to use, the cap 11 of the transfer device 10 may be first screwed onto the bottle 1, and then cap 12 may be screwed onto bottle 2. The latter step may entail rotating bottle 2 relative to the transfer device 10. A user may place bottle 1, once it has been threadedly engaged with cap 11, in a generally horizontal position in order to keep fluid from draining out of bottle 2 prematurely—that is, prior to its being completely installed by threaded engagement with cap 12. Alternatively, the order in which the caps are screwed on may be reversed.
The device may be assembled such that each of the caps 11, 12 are engaged to respective bottles 1, 2 to form a system for transferring fluid between the bottles 1, 2. The system may be disposed in a vertical orientation. In the vertical orientation, the receiving bottle 1 may be disposed in an upright position, and the residue-containing bottle 2 may be inverted above the receiving bottle 1 with the transfer device 10 disposed between the bottles 1, 2.
FIGS. 4-6 may depict another exemplary embodiment 20 of a transfer device. The transfer device 20 may comprise a pair of screw-on caps 21, 22. Each of the caps 21, 22 may have a cylindrical body defining an interior channel and an interior surface upon which a respective thread set is disposed. Each of the caps 21, 22 may further have an opening configured to receive a portion of a bottle at one end of the cylindrical body and a top portion disposed at the opposite end of the cylindrical body. The top portion of each cap 21, 22 may have a bore defined therethrough such that a hollow shaft 23 having an internal lumen may be slip-fitted through the bores in top portions of the first and second caps 21, 22 prior to assembly. The internal surface of the top portion of each cap 21, 22 may define a generally circular rim- like projection 27, 28. Each rim- like projection 27, 28 may surround the bore of the respective cap 21, 22. The shaft 23 may be fabricated of a short piece of ½ inch polyethylene tubing or the like. As shown in exemplary FIG. 6, the shaft 23 may have flared end portions 24, 25 wherein the flared end portions 24, 25 may have a diameter greater than a diameter of a middle portion of the shaft 23.
FIG. 6 can depict a cross-section of the exemplary transfer device 20 of FIGS. 4 and 5. During installation, the cap 21 may be screwed onto a bottle 1 having an interior chamber, a mouth in fluid communication with the interior chamber, and an external thread surrounding the mouth. As the cap 21 is screwed over the external thread of the bottle 1, a first flared end portion 24 of the shaft 23 may be compressed between the rim-like projection 27 on the cap 21 and the leading edge of the mouth of the bottle 1. When the flared end portion 24 of the hollow shaft 23 is so compressed, a substantially leak-tight joint may be formed between the interior of the bottle 1, the interior channel of the first cap 21, and the internal lumen of the hollow shaft 23.
The cap 22 may then be screwed onto a bottle 2 (not shown) having an interior chamber, a mouth in fluid communication with the interior chamber, and an external thread surrounding the mouth. As the cap 22 is screwed over the external thread of the bottle 2, a second flared end portion 25 of the shaft 23 may be compressed between the rim-like projection 28 on the cap 22 and the leading edge of the mouth of the bottle 2. When the second flared end portion 25 of the hollow shaft 23 is so compressed, a substantially leak-tight joint may be formed between the interior of the bottle 2, the interior channel of the first cap 22, and the internal lumen of the hollow shaft 23.
Once the ends of the shaft 23 have been so compressed, seals which are adequate for preventing the leakage of a highly viscous fluid at the junctures between the shaft and the caps 21, 22 may be formed. In this configuration, a substantially leak-tight connection may be formed between the first bottle 1, the channel of the first cap 21, the lumen of the hollow shaft 23, the channel of the second cap 22, and the second bottle 2. Because the shaft 23 may be present in the device 20, the caps 21, 22 may be free to rotate independently of each other and independently of the shaft 23. As a consequence, after cap 21 has been screwed onto bottle 1, cap 22 can then be screwed onto bottle 2 without a user having to rotate the latter bottle. This configuration may thereby expedite the installation process.
A spacer member 26 may be provided between the caps 21, 22 to facilitate vertical alignment and independent rotation of the caps 21, 22. The spacer member may have a central bore disposed coaxially with the bores of the caps 21, 22. Accordingly, the hollow shaft 23 may extend from the channel in the first cap, through the bore in the top portion of the first cap, through the bore in the spacer member 26, through the bore in the top portion of the second cap 22, and finally into the channel in the second cap. The spacer member 26 may be rotationally fixed to the hollow shaft 23. In this embodiment, the first bottle 1, the second bottle 2, the first cap 21, the second cap 22, and the hollow shaft 23 may all be independently rotatable relative to one another. In an alternate embodiment, the spacer 26 may be free to rotate independently from the hollow shaft 23. So configured, the first bottle 1, the second bottle 2, the first cap 21, the second cap 22, the hollow shaft 23 and the spacer member 26 may all be independently rotatable relative to one another. Allowing the caps and other components to rotate freely may facilitate installation of the device onto the first and second bottles 1, 2.
A vent (not shown) may be provided in a side wall along the cylindrical body of one or both of the caps 21, 22. Prior to installation of the respective cap 21, 22 onto a bottle, the vent may fluidly connect with the channel of the respective cap 21, 22. When the cap 21 is engaged with a bottle 1 such that the flared end of the hollow shaft 23 is engaged between the rim-like projection of the respective cap 21, 22 and the edge of the mouth tip of the respective bottle 1, 2, the substantially leak-tight joint between the bottle 1, 2, the cap channel, and the lumen of hollow shaft 23 may prevent the vent from fluidly connecting with internal chamber of the bottle 1, 2 and the lumen of the hollow shaft 23. In other words, the connection between the bottle 1 and the lumen of the hollow shaft 23 may be substantially sealed and may not fluidly connect with the vent. Providing one or more vents may allow air disposed in the threads of the caps 21, 22 and the bottles 1, 2 to be released, thereby facilitating engagement of the respective threads.
The foregoing description and accompanying figures illustrate the principles, preferred embodiments and modes of operation of the invention. However, the invention should not be construed as being limited to the particular embodiments discussed above. Additional variations of the embodiments discussed above will be appreciated by those skilled in the art.
Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive. Accordingly, it should be appreciated that variations to those embodiments can be made by those skilled in the art without departing from the scope of the invention as defined by the following claims.
