[ What is claimed is:] [1.] A pump dispenser for a viscous flowable fluid material comprising a pump head, having at its lower end an attachment means for the fluid-tight replacable attachment of a replacable reservoir of the fluid material, the pump head having a mechanical hand-operable pump by means of which the material may be pumped from the reservoir to a dispensing orifice at the end of a nozzle;a replacable reservoir of the fluid material replacably attached at the lower end of the pump head by means of the attachment means, the reservoir having a bottom which when the reservoir is attached to the pump head is distal to the pump head and having an upper end which when the reservoir is attached to the pump head is proximal to the pump head, with a longitudinal axis between the upper end and bottom;characterized in that the reservoir contains adjacent segments of differently colored toothpaste material said segments being in contact with each other so as to produce toothpaste of a striped appearance on dispensing and the reservoir can be attached to the pump head only in one or more pre-set orientations relative to the pump head and further wherein, the lower end of the pump head comprises a skirt, and the upper end of the reservoir is a shaped end of the shape and size which can mate smoothly with a fluid tight fit with the skirt in a male-female type cooperation when the reservoir and skirt are presented to each other in the longitudinal axis direction of the reservoir, so that the reservoir cannot rotate about the longitudinal axis relative to the pump head.
