ABSTRACT:
A closure device for a squeeze tube that is squeezed to expel the contents thereof, the closure device being of the type comprising a first portion provided with a dispensing orifice and a second portion provided with a stud suitable for co-operating with the dispensing orifice in order to close it and also to open it; the first and second portions are associated with each other on a permanent basis while still being capable of being displaced one relative to the other. The stud is continuously urged towards its closed position by a resilient member. According to the invention, the first portion comprises a sealed thrust device suitable for acting against the resilient member in the stud-opening direction so that in the closed position the stud closes the dispensing orifice under drive from the resilient member, the thrust device then being inactive, while in the open position, the stud opens, the dispensing orifice under drive from the thrust device.
