Claim 3
Dependent Claim 53 words
Apparatus as claimed in claim 1 characterized in that the sealing member (9) has a space therein which is filled with viscous fluid (10), the pressure plate (29) causing flow of the viscous fluid (10) so that the sealing member (9) is deformed locally so as to seal each of the openings (27).
Claim 4
Dependent Claim 53 words
Apparatus as claimed in claim 1 characterized in that the sealing member (32) has projections (31) thereon arranged in registration with the respective cavities (41), the pressure plate (49) contacting the projections (31) and applying pressure thereto which deforms the sealing member (32) locally so as to seal each of the openings (47).
Claim 5
Dependent Claim 54 words
Apparatus as claimed in claim 1 characterized in that the pressure plate (51) has projections (50) which contact the sealing member (67) and which are in registration with the respective cavities (61), whereby the sealing member (67) is deformed locally by the pressure plate (51) so as to seal each of the openings (57).
Claim 6
Dependent Claim 33 words
Apparatus as claimed in any preceding claim characterized in that the apparatus is provided with heating means (23, 28; 43, 48; 63, 68) for heating liquid (A) in the cavities (21; 41; 61).
