ABSTRACT:
A flexible device for efficiently emptying the viscous contents of a flexible, plastic tube having a longitudinal, overlapping, sealed seam. The flexible device is a generally planar, elongated body having a slot of shorter length extending entirely through the body. The slot has a wider entrance and tapers to a narrower exit to allow an embossed, flattened and sealed end of the plastic, flexible, walled tube to be inserted, and to enable the flexible device to be pushed along the plastic, flexible, walled tube and to have the slot of the device stay in position by a spring-like, clamping action of the slot with the knife-like scrapping rear edge, gripping the flattened flexible wall tube.
