LOCKABLE TUBE ROLLER A device for winding up collapsible tubes, having open and closed ends, to allow full expression of contents from the open end and to prevent the wound tube from unwinding. The device includes an elongated slot shaped opening in one member or mandrel for receiving the closed end of a tube, such as a toothpaste tube. After the tube has been inserted into that slot and some amount of tube contents has been expressed, a handle, pivotally attached to one end of the member containing the slot, is pivoted to an open position not overlying the slot and substantially normal to the longitudinal axis of the mandrel and is used to wind the tube. After winding, the handle will be pivoted back to its closed position where it is horizontally offset from and overlies at least a part of the mandrel and will rest against the wound layer or layers of turbine there between. Because of the cooperative relationship of the handle and the mandrel, the tube is prevented from unwinding. |
