Abstract
Abstract A fluid dispenser for a bulk container for portable liquids or the like. A rigid outer box contains a sealable flexible fluid-containing plastic bag having a tubular dispenser sleeve mounted at an oblique angle to a plastic mounting fixture which is attached to the box that is also sealed to the outer surface of the fluid-containing bag. The dispenser, which is stored prior to use within the box, may be withdrawn and snapped into a horizontal position into a plastic clamp that is part of the mounting fixture and which prevents rotation of the sleeve. A turncock barrel rotatable within the dispensing sleeve has a sharp cutting tip which is normally angled with the angled end of the sleeve positioned to prevent piercing of the fluid bag. When rotated a half turn, the sharp cutting tip pierces the bag to permit the fluid to pass into the bore of the barrel and out through mating apertures in the barrel and sleeve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
In combination with a bulk fluid container comprising a flexible sealed fluid containing bag supported within a rigid outer container, a fluid dispenser including: a tubular sleeve having a first end attached to the fluid containing bag at an oblique angle and a second end extendable from the outer surface of the rigid outer container, said second end having a first fluid dispensing aperture in the lower wall of said sleeve; and a tubular valve member rotatably positioned within the bore of said tubular sleeve, the first end of said valve member being formed at an oblique angle and having a sharpened end portion, the second end of said valve member having a second fluid dispensing aperture in the wall and handle means for rotating said valve member within said sleeve between a first "off" position and a second "on" position; in said first "off" position, said sharpened end portion of said valve member extending within said sleeve to, but not touching said fluid containing bag and said first and second fluid dispensing apertures being non-aligned; and in said second "on" position said sharpened end entering said fluid containing bag and said first and second fluid dispensing apertures being substantially aligned.

In combination with a bulk fluid container comprising a flexible sealed fluid containing bag supported within a rigid outer container, a fluid dispenser including: a tubular sleeve having a first end attached to the fluid containing bag at an oblique angle and a second end extendable from the outer surface of the rigid outer container, said second end having a first fluid dispensing aperture in the lower wall of said sleeve; and a tubular valve member rotatably positioned within the bore of said tubular sleeve, the first end of said valve member being formed at an oblique angle and having a sharpened end portion, the second end of said valve member having a second fluid dispensing aperture in the wall and handle means for rotating said valve member within said sleeve between a first "off" position and a second "on" position; in said first "off" position, said sharpened end portion of said valve member extending within said sleeve to, but not touching said fluid containing bag and said first and second fluid dispensing apertures being non-aligned; and in said second "on" position said sharpened end entering said fluid containing bag and said first and second fluid dispensing apertures being substantially aligned.
Claim 3
Dependent Claim
36 words
The fluid dispenser claimed in claim 1 wherein said fluid containing bag is pierced by said sharpened end portion by the initial rotation of said tubular valve member from its first position to its second position.
Claim 4
Dependent Claim
47 words
The fluid dispenser claimed in claim 1 wherein said fluid containing bag is pierced by the said sharpened end portion by the longitudinal insertion of said tubular valve member into the bore of said tubular sleeve while said valve member is in its second "on" rotational position.
Claim 5
Dependent Claim
43 words
The fluid dispenser claimed in claim 1 wherein said first end of said tubular sleeve is attached at an oblique angle to one surface of a first plate member, the opposite surface of said plate member being attached to said fluid containing bag.
Claim 6
Dependent Claim
48 words
The fluid dispenser claimed in claim 4 wherein said tubular valve member has a resilient annular ring around its outer surface, said ring being located to engage an annular slot in the bore of said tubular sleeve to prevent longitudinal movement of said valve member within said sleeve.
Claim 7
Dependent Claim
52 words
The fluid dispenser claimed in claim 5 further including a box attachment member having substantially parallel vertical slots in the external surface to engage a corresponding aperture in the surface of said rigid outer container and a generally U-shaped interior having a width corresponding to the external diameter of said tubular sleeve.
Claim 8
Dependent Claim
53 words
The fluid dispenser claimed in claim 6 wherein said box attachment member is hingedly connected to one edge of said first plate member whereby said fluid dispenser may be stored within said rigid outer container and may be removed from said container and locked against rotational movement in said U-shaped box attachment member.
Claim 9
Dependent Claim
31 words
The fluid dispenser claimed in claim 7 wherein said first and second fluid dispensing apertures are longitudinal slots in said second ends of said tubular sleeve and said valve member, respectively.
Claim 10
Dependent Claim
33 words
The fluid dispenser claimed in claim 7 wherein said first and second fluid dispensing apertures are holes in the walls adjacent the second ends of said tubular sleeve and said valve member, respectively.
