ABSTRACT:
A device for administering a medicine in the form of a spray, the medicine being constituted by a mixture of at least two substances that must be stored separately prior to use, the device comprising a volume which is divided into two compartments by a membrane 2 suitable for puncturing or tearing. The volume is defined by a receptacle 1A, 1B which is generally tubular in shape, and which is open at both ends. A suction and spray pump 4 is crimped onto one end thereof while its opposite end has a free piston 6 slidably received in the tubular element 1B to reduce the inside volume thereof as the pump sucks the content out from the tubular element after the membrane has been punctured.
