A dispenser for dispensing liquid or paste-like substances includes a dispenser head with a mouth opening. At least a part of the dispenser head with the mouth opening is extendable and retractable with respect to a surrounding housing wall. A surface that comes in contact with the mouth opening or with an end face region of a protruding wall formed so as to surround the mouth opening encloses an acute angle with a vertical in a cross-section in which the surface appears as a line, and, in the retracted state, this region is in contact with an identically-formed support surface on the housing wall which faces the mouth opening or the end face region. |
