1. A closure for a container, the closure having an outer skirt and an inner skirt, the inner skirt being engagable with a container neck and comprising one or more regions of weakness arranged to break andor deform if an attempt is made to remove the closure from a neck following first application, whereby to prevent re-application.
2. A closure as claimed in claim 1, in which the regions of weakness comprise one or more lines of weakness.
3. A closure as claimed in claim 1, in which the regions of weakness are frangible.
4. A closure as claimed in claims 1, in which the regions of weakness extend generally longitudinally along the inner skirt.
5. A closure as claimed in claim 1, in which the inner skirt is generally cylindrical.
6. A closure as claimed in claim 1, in which the inner skirt comprises snap engagement means.
7. A closure as claimed in claim 6, in which the snap engagement means comprise a snap bead.
8. A closure as claimed in claim 7, in which the snap bead is positioned at an open end of the inner skirt.
9. A closure as claimed in claim 8, in which the snap bead is discontinuous.
10. A closure as claimed in claim 1, in which the closure comprises a base and a lid, the skirts forming part of the base.
11. A closure as claimed in claim 1, in which the base and lid are joined by a hinge.
12. A closure as claimed in claim 1, in which the closure comprises a self-closing valve.
13. A closure as claimed in claim1, in which the closure further comprises tamper-evident means.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Low-head modular hydraulic machine including:
at least one water runner that can be removed manually, on one axle;
at least one user device driven by said axle for transforming the energy generated by said water runner;
a control module for drawing away part of the energy generated by said water runner and for stabilizing the rotation of said water runner at a predetermined operating speed and force;
characterized in that said hydraulic machine can be adapted to different head heights by replacing or adjusting said water runner.
2. The modular hydraulic machine of claim 1, wherein said user device includes an electric generator.
3. The modular hydraulic machine of claim 2, wherein said control module acts on the electric current generated by said generator.
4. The modular hydraulic machine of claim 1, wherein the energy drawn by said control module is used for at least one of the following uses: charging batteries, dissipation in discharge resistances, generation of hot or cold, pumping fluids, pumping drinking water.
5. The modular hydraulic machine of claim 1, wherein said user device includes a fluids’ pump.
6. The hydraulic machine of claim 5, wherein said control module acts on the flow drawn from said pump.
7. The modular hydraulic machine of claim 1, wherein said user device includes a fluid compressor designed to generate cold.
8. Modular hydraulic machine according to claim 1, wherein said user device includes a hot water and steam generator.
9. The modular hydraulic machine of claim 1, wherein said control module keeps said operating speed and power constant without variation in the water flow of said water runner.
10. Hydraulic micro-station, for an installation with or without a dam, including a watertight container, divided in a first chamber and a second chamber through a partition wall; said container including:
an inlet opening for bringing the water into said first chamber;
a filtering screen for retaining coarse solid bodies coming from the inlet conduit, and a decanting zone in said first chamber;
a filter allowing said first chamber and second chamber to communicate;
a hydraulic machine according to claim 1, lodged in said second chamber.
11. The hydraulic micro-station of claim 10, including in said first chamber, a purging gate actuated automatically by an actuator sensitive to the pressure variation between said first and second chamber, said purging gate allowing sediments to be eliminated from said decanting zone.
