ABSTRACT:
A dispenser device comprises a container body having two axial ends. A receptacle made from an elastic material is placed in the container body and contains the substance to be dispensed. A dispensing head provided at a first axial end of the container body communicates with the receptacle and can be opened and closed on command. The dispenser device further includes a bottom base provided at the second axial end of the container body which is opposite the dispensing head and to which the receptacle is fixed. An elongation limiter is fixed to the dispensing head and to the bottom base to limit the separation between the dispensing head and the bottom base.
