Multiple channel single spike for a liquid dispensing system
A spike for dispensing fluids from a flexible bag, wherein the spike includes multiple fluid channels which transfer liquids from the bag to an enclosed dispensing chamber and air from the enclosed chamber to the bag to permit and control fluid flow within the system.
1. A system for dispensing a fluid from a bag, the system comprising:
a bag including a fluid therein;
a spike puncturing an outer wall of said bag, said spike comprising:
a shaft comprising a first and a second end and an elongated body therebetween and having an outer surface;
a first channel internal to said shaft, said first channel having a first fluid inlet, and a first aperture allowing said fluid to flow from said bag through said first channel;
a second channel internal to said spike, said second channel being noncontiguous with said first channel and having a second fluid inlet and a second aperture allowing said fluid to flow through said second channel;
a puncturing tip located within said fluid, said puncturing tip comprising:
a generally cone-shaped portion having a base and an opposing truncated tip, said base being sized and shaped for attaching to said first end of said shaft and being attached to said first end.
2. The system of claim 1 , said puncturing tip further comprising:
a puncturing shaft having two opposing ends and an elongated body therebetween, a first end of said two opposing ends being sized and shaped to attach to said truncated tip and said first end attached to said truncated tip, and a second end of said two opposing ends being a generally cone-shaped element sized and shaped for puncturing a collapsible bag of liquid.
3. The system of claim 1 , wherein said shaft is generally cylindrical.
4. The system of claim 1 , wherein said shaft is generally a polygonal prism.
5. The system of claim 4 , wherein said shaft is generally a hexagonal prism.
6. The system of claim 1 , wherein said fluid comprises potable water.
7. The system of claim 1 , wherein fluid flowing from said bag flows into an enclosed chamber.
