Abstract
Abstract A dispensing and packaging technique for use with fluent, semiliquid foods of the type which must be handled gently to avoid bruising or otherwise adversely effecting the quality of the food product. The technique includes storing a quantity of the food in an elevated supply trough and then pumping the food from the trough, in measured charges, to the packaging containers. The technique includes an arrangement by which the food product advances along a straight line from the trough to the container thus avoiding any tubing bends, pressure variations, etc. which might affect adversely the food product.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
277 words
An apparatus for dispensing a fluent food product comprising: a hopper having sidewalls and a bottom wall and at least one opening formed in said bottom wall; a cylinder associated with each of said at least one openings in said bottom wall of said hopper, said cylinder having an inlet end and an outlet end each of said cylinders being secured to said hopper in registry with its associated opening; a dispensing tube having an inlet and an outlet end, the inlet end of said dispensing tube being received slideably and coaxially within the outlet end of said cylinder; means sealing said tube and cylinder for sliding reciprocating movement therebetween; means mounting said hopper and said at least one cylinder for reciprocating movement in a heightwise direction and in relation to said dispensing tube, said dispensing tube and cylinder being aligned to define a substantially straight flow path; inlet valve means associated with said inlet end of each of said cylinders comprising a slide valve interposed between the bottom of said hopper and the upper end of each of said cylinders, said slide valve including a plate having openings equal in number and spacing to the openings in the bottom of said hopper and each said cylinder, the region between said openings in said plate being dimensioned to close fully the passage between the hopper and each cylinder to confine the food in each cylinder therein; an outlet valve located at the outlet end of said dispensing tube; means for opening said outlet valve when said slide is in a closed position and for closing said outlet valve when said slide valve is in an open position.
