A creamy substance dispenser is formed from a small number of components of easy and economical construction and assembly. The dispenser includes a main body defining a metering chamber communicating with a creamy substance container, within the chamber there being sealedly slidable a piston from which is projected a hollow stem extending into a hollow appendix projecting from a skirt rigid with the main body. The appendix is provided with a discharge hole closable by the end of said stem and biased by a spring, the stem freeing said discharge hole when made to translate by manual action.
