Description
The present invention relates to a feed tube for a ~ispenser of potable liquid.
BACRGROUND OF THE I~TIO~
In order to prevent contamination of bottled liquid, the industry has developed caps for bottles which are intended to remain in place even after the bottle has been inverted onto a dispenser. In order to enable the cap to remain in place the dispensers are equipped with upstanding feed tube~ which either pierce the caps or cooperate with valves in the caps.
Dispensers of this type have an inverted seat adapted to receive a neck of an inverted bottleO The seat has a fluid flow channel extending therethrough in which the feed tube is positioned.
Despite all the care and attention that has gone into preventing the contamination of the bottled liquid, no measures have been taken to prevent contamination of the dispenser unit via the feed tube. When the bottle is removed from the dispenser, the dispenser is susceptible to contamination through exposed ~luid flow passages in the feed tube~

DETAILEI) DES(~RIPTION OF T~3 PREFERRED EMBODIMENT
The preferred embodiment, a feed tube assembly for a dispenser of potable liquid will now be described with reference to FIGURES 1 and 3. F~GU~ES 1 through 3 illustra-te diverse w~ys in which the invention can be put into practise.
~he feed tube assembly illustrated in FIGURE 1, will generally be identified by reference numeral 10. The feed tube assembly illustrated in FIGURE 2I will generally be identified by reference numeral 11. The feed tube assembly illustrated in FIGU~E 3, will generally be identified by reference n~meral 12.
Feed tube assemblies 10 through 12 illustrate alternatP
ways to put the present invention in to practise. All embodiments are placed within dispensers for potable liquid having a ba~a 14 with an inverted seat 16 which is adapted to receive a liquid container 20. Seiat 16 has a fluid flow channel 18 extending therethrough. Each feed tube assembly includes a feed tube 40 having radial fluid flow passages 22 which maintain fluid communication with fluid flow channel 18 of seat 16. Each feed tube assembly has an hygienic guard sleeve 24 telescopically positioned on feed tube 40. Sleeve 24 is axially movable between a closed position obstructing fluid flow passages 22 and an open position spaced from fluid flow passages 22. Different means are provided for positioning and maintaining sleeve 24 in the closeclposition when container 20 is removed a~ will hereinafter be ~Eurther described. When ~leeve 24 is in the closed position contaminants are prevented Z5 from entering through fluid flow passages 22. All embodiments of feed tube assembly have an outwardly projecting contact surface 30 on sleeve 24. When container 20 is placed on seat 16, container 20 exerts a force upon contact surface 30 thereby moving sleeve 24 to an open position and exposing fluid flow passages 22 to a flow of liquid from container 20. A first annular seal 50 is disposed between ~eed tube 40 and a first end 49 of sleeve 240 A variety of hygienic caps have been developed for container 20. There is illustrated a friction fit flapper-stylei of valve body 52. Valve body 52 has a central passage 54, closed by a flapper member 56.
Referring to FIGURE l, contact surface 30 has a peripheral edge 32 with concave engagement means. A clip 34 is positioned on contact surface 30. Clip 34 is adapted to engage a rim 36 of container 20. A convex annular seal 38 is positioned in fluid flow channel 18 and serves as mating engagement means as will be hereinafter further described.
The operation and use of feed tube assembly 10 will now be described with r~ference to FIGURE 1. When container 20 is placed onto seat 16, rim 36 of container 20 engages clip 34.
The weight of container 20 exerts a force upon contact surface 30 of sleeve 24 thereby causing sleeve 24 to slide to an open position exposing fluid flow passages 22 to a flow of liquid from container 20. As container 20 is placed in position flapper valve 56 pivots inwardly to permit feed tube 40 to extend up through central passage 54 of valve body 52. When container 20 is removed the engagement between rim 36 and clip 34 causes sleeve 24 to be drawn into the closed position as container 20 ~s removed.- In the closed position annular seal 38 on fluid flow channel 18 æealingly engages concave engagement means on peripheral edge 32 o~ contact surface 30.
This engagement both maintains sleeve 24 in the closed position when container Z0 is removed. As long as sleeve 24 is maintained in the closed po~ition the ingress of cont~minants through radial fluid flow passages 22 is prevented.
Referring to FIGURE 2, ~eed tube assembly 11 has an underlying spring 44. Spring 44 exerts a biasing force upon sleeve 24 to maintain sleeve 24 in the closed position when container 20 is removed. A first annular seal 50 is disposed between feed tube 40 and a first end 49 of sleeve 24. A second annular seal 48 i8 disposed between contact surface 30 and ~luid flow channel 18 of seat 16~
35The use and operation of feed tube assembly 11 will now be described with re~erence to FI~URE 2. When container 20 is placed onto seat 16, flapper valve 56 pivot~ inwardly f~
permitting feed tube 40 to extend up through central passage ~, 54 of val~e body 52. The weight of container 20 overcomes the biasing force of spring 44 causing sleeve 24 to s]ide to an open position exposing fluid flow passages 22 to a flow of liquid from container 20. When container 20 is removed the biasing force of spring 44 causes sleeve 24 to be urged into the closed position as container 20 is remo~ed. In the closed position sleeve 24 prevents the ingress of contaminants through radial fluid flow passages 22. The sealing is improved by having annular ~eal 48 sealing the interface between contact surface 30 and fluid flow channel 18, and annular seal 50 sealing the interface between first end 49 of sleeve 24 and feed tube 40.
Referring to ~IGUR~ 3, with feed tube assembly 12 spring 44 has a flexible sealing drape 53 as an alternative to annular seal 48. The use and operation is otherwise the same as with feed tube a~sembly 11.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as defined by the claims.
