A device for squeezing toothpaste from a squeezable tube (T) involves a winding spindle (1) onto which the tube is wound in a flattened state within an embracing clip (2). Turning a twist-grip (5) of the spindle (1) draws the tube through jaws (10,11) of the clip (2) to dispense toothpaste by flattening the tube under pressure from one of the jaws (11) as the tube passes towards the jaws over a projection (15) of a foot (14). The foot (14) extends from one end of a curved spring-section (12) of the clip (2), and the jaws (10,11) are defined respectively by a projection (13) from the foot (14) and a free end of the spring-section (12). When turning of the twist-grip (5) is relaxed, any significant unwinding from the spindle (1) and regressive movement of the tube outwardly from the clip (2) is precluded by the grip on the tube exerted between the jaws (10,11). When the tube is virtually empty, abutment of an extension (17) from the jaw (11) and of the foot (14) under the moulded flange (F) of the tube-nozzle (N) precludes further turning of the spindle (1). |
