Abstract: A pumpless dispenser especially intended for dispensing viscous fluids. The dispenser includes a supple pouch having first and second ends, a sidewall that can be arranged to form first and second opposed surfaces, and an outlet. The pouch contains a viscous fluid food product therein. The dispenser also includes a housing configured and dimensioned for receiving the pouch; and a compression assembly for pressing the pouch so as to urge the viscous fluid food product content toward the outlet. This assembly includes a roller having a pressing surface disposed adjacent the first surface of the pouch and a planar surface disposed adjacent the second surface of the pouch. The dispenser further includes a closure member engaged with the outlet for closing the outlet. This member is capable of opening the outlet so as to cause the roller to move along the pouch surface toward the outlet by gravity for expelling the viscous fluid food product through the outlet.

Abstract: An antiseptic soap dispenser has a dispensing system (28) which includes a pressure actuated platen (32) and a moveable roller (94) for dispensing soap from a replaceable container (12). A dispensing tube (10) with an integral self-sealing valve (40) at a downstream end is connected to a neck (20) of the container. Hand pressure on the platen compresses a upstream end of the dispensing tube between the platen and the roller. With increasing pressure, the roller moves progressively down the tube to dispense soap through the valve. A volume regulator (111) controls the amount of soap dispensed. The platen returns quickly to its at-rest position once the pressure is removed, avoiding complete compression of the pathway by the roller. This minimizes air ingress, and resultant contamination of the soap. Optionally, a filtered vent (14) in a wall (22) of the container allows filtered air to enter the container in place of the soap dispensed.

Abstract: In the blood Bank area of a clinical laboratory a blood dispensing device is described capable of being used in conjunction with tubing containing blood which is attached to a blood donor bag. The end of said tubing is fed through one end of said device until it passes through the opposite end of the device at which point means are available to cut the tubing. The device is fitted with a knurled wheel or roller guided by an inclined track or ramp which upon turning the wheel in one direction causes the tubing to be squeezed or compressed thus allowing blood to be dispensed in a controlled dropwise fashion. In the opposite direction the wheel decompresses the tubing allowing it to be fed through once again in order to repeat the process as desired.

Abstract: The dispenser progressively empties a tube from one end by applying pressure to the other end. The dispenser comprises a support on which the tube rests. A handle is pivotally mounted on the support and has a range of reciprocating movement between first and second pre-determined points for applying an increment of pressure to one end of the tube. A ratchet is connected to the handle and permits the roller to move incrementally forward against the tube exerting pressure thereon during each reciprocation. As the handle moves between the first and second pre-determined points, it moves to an intermediate point defined relative to the point where the handle is pivotally mounted on the support and beyond the point to an over-center position where the roller releases sufficient pressure on the contents of the tube to prevent residual emptying or dripping.

Abstract: An automatic toothpaste dispenser employs a roller-type squeeze device that is driven along the toothpaste tube simultaneously with the opening of a gate that permits the toothpaste to flow. After the desired amount of toothpaste has been dispensed, the roller is automatically retracted and the gate is simultaneously closed. However, the retraction of the gate only continues until the gate is closed, which results in a ratchet-like effect, the roller being retracted a smaller distance than that by which it is advanced.
