摘要

One of the tray walls (2) is entirely stiff or stiffened by lengthways rib and arranged on the lingual side. The fillable wall has a sleeve (3) whose interior is reached via a fill opening (6) and which connects to an outflow aperture (7) directed towards the impression area of the tray. Several apertures (7) can be spread over the impression area of the tray and in this case the sleeve runs back to the filling (6) end of the tray. Outflow can be through slots or again by openings into the impression area. The openings are furnished with a brush type closure and fill opening (6) or sleeve can be closed off by a mass-blocking valve.
