Liquid dispensing device

Abstract

A liquid dispensing device for a container, and associated systems and methods, are disclosed. The liquid dispensing device can include a penetrating tip configured to penetrate a container, which is configured to have a liquid disposed therein. Relative movement of the penetrating tip and the container toward one another can be operable to create an opening in a portion of the container, and the liquid can dispense from the container through the opening.

What is claimed is: 
     
         1 . A liquid dispensing system, comprising:
 a support member;   at a blade fixedly coupled to the support member, the blade operable to penetrate a container having a liquid disposed therein and create an opening in a portion of the container to dispense the liquid; and   at least one receptacle, said receptacle comprising a well of an electrophoresis gel configured to receive the liquid dispensed from the container.   
     
     
         2 . The system of  claim 1 , wherein the blade is adapted to be disposed in the container. 
     
     
         3 . The system of  claim 2 , further comprising a plunger configured to be disposed within the container and form a seal about an inner surface of the container, wherein the plunger and the inner surface define a volume in the container that initially includes the liquid, and wherein the plunger is movable to cause the blade to create the opening and to cause the plunger to reduce the volume and dispense the liquid from the container through the opening. 
     
     
         4 . The system of  claim 3 , wherein the blade comprises a plurality of blades and a plurality of plungers are associated with the plurality of blades. 
     
     
         5 . The system of  claim 1 , wherein the blade is adapted to penetrate the container from a location outside the container. 
     
     
         6 . The system of  claim 1 , wherein the blade is plurality of blades spaced apart to correspond with a plurality of receptacles to facilitate dispensing liquid from a plurality of containers to the plurality of receptacles. 
     
     
         7 . The system of  claim 5 , wherein the blade is adapted to penetrate the container at least twice. 
     
     
         8 . The system of  claim 1 , wherein the blade is configured to extend through a bottom of the receptacle. 
     
     
         9 . The system of  claim 1 , wherein the blade is disposed above the gel. 
     
     
         10 . The system of  claim 1 , wherein the blade is supported by a housing for the receptacle. 
     
     
         11 . The system of  claim 1 , wherein the receptacle is adapted to form a sealed space with the container within which the liquid is dispensed. 
     
     
         12 . The system of  claim 1 , wherein the liquid dispenses from the container through the opening while the blade extends through the opening. 
     
     
         13 . The system of  claim 1 , wherein the liquid dispenses from the container through the opening after the blade has been withdrawn from the opening. 
     
     
         14 . The system of  claim 1 , wherein the blade is operable to form the opening such that the liquid is dispensed from the container by positive pressure within the container. 
     
     
         15 . The system of  claim 14 , wherein the positive pressure is generated by disposing a lid on the container, by compressing walls of the container, by heating the container, or a combination thereof. 
     
     
         16 . The system of  claim 1 , wherein the liquid is dispensed from the container by centrifugal force or gravity. 
     
     
         17 . A liquid dispensing container support apparatus, comprising:
 a support structure;   a blade fixedly coupled to the support structure and operable to penetrate a container having a liquid disposed therein;   a plurality of receptacles, each receptacle comprising a well of an electrophoresis gel configured to receive the liquid dispensed from the container; and   an opening extending through the support structure and having a top portion and a bottom portion, wherein the top portion is configured to receive and support the container and the bottom portion is configured to be disposed over one of the plurality of receptacles to receive the liquid dispensed from the container.   
     
     
         18 . The apparatus of  claim 17 , wherein the opening comprises a plurality of openings, and wherein the plurality of openings are spaced apart to correspond with the plurality of receptacles to facilitate dispensing liquid from a plurality of containers to the plurality of receptacles. 
     
     
         19 . The apparatus of  claim 17 , wherein the top portion of the opening is configured to interface with the container. 
     
     
         20 . The apparatus of  claim 19 , wherein the top portion of the opening is configured to form a seal with the container and define, at least in part, a sealed space for dispensing liquid from the container to one of the plurality of receptacles. 
     
     
         21 . The apparatus of  claim 19 , further comprising a sleeve configured to interface with the container and the top portion of the opening. 
     
     
         22 . The apparatus of  claim 17 , further comprising a vent channel to relieve gas pressure in the opening as the container is disposed in the opening. 
     
     
         23 . A method of loading a sample into an electrophoresis gel, comprising:
 forming an opening in a portion of a container using a blade that is fixedly coupled to a support member; and   dispensing the liquid from the container through the opening into a well of an electrophoresis gel.   
     
     
         24 . The method of  claim 23 , wherein an opening is formed from inside the container. 
     
     
         25 . The method of  claim 23 , wherein an opening is formed from outside the container. 
     
     
         26 . The method of  claim 23 , wherein an opening is formed from both inside and outside the container. 
     
     
         27 . The method of  claim 23 , wherein forming an opening comprises at least one of penetrating, cutting, puncturing, and rupturing a portion of the container.
