A dispensing device for flowable material comprises a rigid tubular housing having a dispensing outlet at one end and a relatively rotatable end cap. A flexible container for the flowable material is made of high tensile essentially non-stretchable material and is located in the housing with one end in communication with the outlet. The other end is connected to the end cap so that rotation of the end cap twists the end of the container to dispense the flowable material. The connection is through a compensating device which, while transmitting the rotation of the end cap, allows the twisted end of the container to move axially in an essentially nonresilient manner but offers sufficient resistance to keep the twisted end along the axis of the housing. |
