Bottle transfer device

Abstract

A device and a system for transferring viscous fluid between a first bottle and a second bottle may be provided. The device and system may comprise a first cap having a first internal thread and a first channel extending through the first cap and a second cap having a second internal thread and a second channel extending through the second cap. The first cap and the second cap may be coupled to one another, and the first channel may be fluidly connected with the second channel.

What is claimed is: 
     
         1 . A device for transferring a fluid comprising:
 a first cap having a first internal thread and a first channel extending through the first cap;   a second cap having a second internal thread and a second channel extending through the second cap;   wherein the first cap and the second cap are coupled to one another, and the first channel is fluidly connected with the second channel.   
     
     
         2 . The device of  claim 1 , wherein the first cap has a first top portion and a first bore extending therethrough, the second cap has a second top portion and a second bore extending therethrough, and the first and second bores provide fluid communication between the first channel and the second channel. 
     
     
         3 . The device of  claim 2 , wherein the first and second caps are welded together. 
     
     
         4 . The device of  claim 2 , wherein the first and second caps are glued together. 
     
     
         5 . The device of  claim 2 , wherein the first and second caps are formed integrally as a single, unitary piece. 
     
     
         6 . The device of  claim 2 , wherein a hollow shaft having an axial lumen is disposed such that it extends from the first channel through the first and second bores into the second channel. 
     
     
         7 . The device of  claim 6 , wherein the hollow shaft has a first flared end portion, and the first flared end portion is disposed within the first channel such that the first flared end portion is configured to be compressed between an internal surface of the first top portion and a surface of a first bottle that engages the first internal thread, thereby providing a substantially leak-tight joint between the first channel and the lumen of the hollow shaft. 
     
     
         8 . The device of  claim 7 , wherein the internal surface of the first top portion comprises a generally circular first rim-like projection. 
     
     
         9 . The device of  claim 7 , wherein the hollow shaft has a second flared end portion, and the second flared end portion is disposed within the second channel such that the second flared end portion is configured to be compressed between an internal surface of the second top portion and a surface of a second bottle that engages the second internal thread, thereby providing a substantially leak-tight joint between the second channel and the lumen of the hollow shaft. 
     
     
         10 . The device of  claim 8 , wherein the internal surface of the second top portion comprises a generally circular second rim-like projection. 
     
     
         11 . The device of  claim 6 , wherein each of the first cap member, the second cap member and the hollow shaft are configured to rotate independently of one-another. 
     
     
         12 . The device of  claim 6 , further comprising a spacer, wherein the spacer comprises a spacer bore that is coaxial with the first bore and the second bore, and the hollow shaft extends through the spacer bore. 
     
     
         13 . The device of  claim 12 , wherein each of the first cap member, the second cap member, and the spacer are configured to rotate independently of one another. 
     
     
         14 . The device of  claim 13 , wherein the spacer is rotationally fixed to the hollow shaft. 
     
     
         16 . The device of  claim 7 , wherein the first cap member comprises an air vent disposed on a side-wall thereof, and the device is configured such that when the first cap member is engaged to a first bottle, the first bottle is not in fluid communication with the air vent. 
     
     
         17 . A system for transferring fluid from a first bottle to a second bottle comprising:
 a first cap having an first internal thread and a first channel extending through the first cap;   a second cap having an second internal thread and a second channel extending through the second cap;   a first bottle having a first interior chamber;   a second bottle having a second interior chamber;   wherein the first cap and the second cap are coupled to one another, and the first channel is fluidly connected with the second channel.   
     
     
         18 . The system of  claim 17 , wherein the first cap has a first top portion and a first bore extending therethrough, the second cap has a second top portion and a second bore extending therethrough, and the first and second bores provide fluid communication between the first channel and the second channel, and the system further comprises a hollow shaft having an axial lumen is disposed such that it extends from the first channel through the first and second bores into the second channel. 
     
     
         19 . The system of  claim 18 , wherein the first bottle has a first mouth tip surface, and the first cap is threaded onto the first bottle such that the first flared end portion of the hollow shaft is compressed between the first mouth tip surface and an interior surface of the first top portion such that a substantially leak-tight joint is formed between the first interior chamber, the first channel, and the lumen of the hollow shaft; and
 wherein the second bottle has a second mouth tip surface, and the second cap is threaded onto the second bottle such that the second flared end portion of the hollow shaft is compressed between the second mouth tip surface and an interior surface of the second top portion such that a substantially leak-tight joint is formed between the second interior chamber, the second channel, and the lumen of the hollow shaft.   
     
     
         20 . The system of  claim 19 , further comprising a spacer, wherein the spacer comprises a spacer bore that is coaxial with the first bore and the second bore, and the hollow shaft extends through the spacer bore;
 wherein the spacer is rotationally fixed to the hollow shaft; and   wherein each of the first cap, the second cap, the hollow shaft, the first bottle, and the second bottle are configured to rotate independently of one-another.
