Apparatus and method for transferring fluids from flexible containers

Abstract

An apparatus and method for transferring fluids from a fluid container to a fluid reservoir are disclosed. More particularly, the fluid transfer apparatus is directed to the transfer of fluids from commercially supplied plastic containers to various fluid and lubricant reservoirs. The invention enables contaminant and drip free transfer of fluids from locations both above and below the reservoir opening and provides for the precise volumetric measurement of the fluid transferred. The fluid transfer apparatus may comprise a cap with a bore through its upper surface configured to closely receive a tube. The tube may be extended with a suitable length of flexible tubing having an inner diameter configured to closely receive the tube. The present invention can also be viewed as providing a method for transferring fluid. In its broadest terms, the method can be described by the following steps: placing the fluid transfer apparatus on the spout of a fluid container, supplying a sufficient amount of torque to the cap, placing the distal end of the tube near a designated port, adjusting the proximal end of the tube such that it is submersed within the fluid, and applying pressure to the exterior surfaces of the fluid container. Once an operator stops applying sufficient pressure to the fluid container the fluid in the apparatus returns to the fluid container. In an alternative method, an operator may extend the tube and perform the fluid transfer by pouring the fluid.
