PROBLEM TO BE SOLVED: To provide a dispenser for a container which can extract a liquid containing a non-polar oil such as paraffin oil from the container. SOLUTION: At least, either of a cylinder 12 or a piston 26 is characteristically formed of a material selected from a resin with a polyester bond and a polyether bond, a resin with an amide bond and a polyether bond and a resin consisting of polybutylene terephthalate. Therefore, even when a non-polar oil such as paraffin oil, for example, is contained in a liquid packed in a container such as a toilet water or a milky lotion, the cylinder 12 or the piston 26 hardly induced a chemical reaction with the oil, as the former shows a low affinity with the latter. Consequently, there is no fear that the cylinder 12 or the piston 26 would absorb the oil and become swollen. |
