Filler for blind cavities e.g. for electronic or medical use has body with two apertures linked to vacuum source and filling product reservoir

摘要

The filler, designed to fill small cavities (11) in the surface (10) of an object (8) with a viscous product (7), consists of a body (1) which is able to move in sealed contact with the surface and has two apertures (2, 5). The first of the apertures which passes over the cavities is connected to a vacuum chamber (3) linked to a standard vacuum generator (4); the second one is connected to the reservoir (6) containing the viscous product, which then fills the evacuated cavities.
