Abstract
A device for compressing flexible tubes containing pastes, creams and the like, provided with a receptacle for storing dental floss, making it easy to handle flexible tubes (2) for storing pasty or creamy products, thus providing the full utilization thereof thanks to a differentiated construction and design, wherein a device (1) inserted through its center gap (6) into the lower part of the flexible tube (2) and manually pushed toward the nozzle runs along and compresses the flexible body (2) to expel the product, said device (1) also being provided with a bevel (5) at one of the ends of its upper side, so that the handling thereof may cause a light displacement as it reaches the point wherein there is an accumulation of the product so that the device (1) is locked on the side edges of the flexible tube (2) after the product is expelled, and, because of such displacement, it is prevented from being pushed back, therefore becoming self-locked so that the next time the user uses same he/she will start dispensing same again by applying a slight pressure thereon, thus avoiding any waste and facilitating the use of pastes and creams.
