ABSTRACT:
A tube squeezing device includes a pair of hollow rollers, a coupling strap in a looped configuration inserted through the rollers, and a connection securing opposite ends of the strap together in offset relation to the remainder of the looped strap. Each elongated hollow roller is made of rigid material and has an interior bore extending between and open at a pair of opposite ends. The coupling strap is made of a substantially resilient flexible inelastic material. The strap has a pair of opposite ends and is of a length sufficient to permit the opposite ends of the strap to extend beyond an adjacent one pair of the pairs of opposite ends of the rollers. The connection secures the opposite ends of the coupling strap together to close the looped strap about adjacent longitudinal portions of the rollers. The connection is disposed in the bore of one of the rollers and to one side of an endless path defined by the looped strap. The closed strap retains the rollers in a spaced apart relationship in which a slot is defined therebetween adapted to receive therethrough a closed end of a flexible fluiddispensing tube. The material of the coupling strap is sufficiently resilient to urge the rollers toward one another to apply squeezing forces to opposite sides of the tube.
