Classification: CPC B  F | IPC B  F

Claim 0:
1. A system for cleaning a device for holding fluid, the system comprising
mechanical wave generating means and
a waveguide comprising
a first end adapted to be in contact with an outer surface of the device
a second end wherein the second end is in contact with the mechanical wave generating means,

wherein
the waveguide comprises a cavity comprising a base portion, the base portion separated from the second end by a distance I,
the mechanical wave generating means is adapted to emit mechanical waves through the waveguide to the outer surface,
the distance I is such that when the mechanical wave generating means emits a succession of mechanical waves through the waveguide to the outer surface, there is an antinode positioned in the waveguide at the distance I from the second end,
a maximum diameter Dmax of the waveguide is less than ½ of a wavelength of the mechanical waves and wherein
the ratio of diameter d of the base portion to the diameter D of the waveguide at the distance I is from 0.2 to 0.9.
