Apparatus for repeatedly applying seals on and mass-sealing an opening of a container with sealing tape comprising:

• a) at least one applicator head (50), having at least one notch (51) with a shape complementary to the opening (21) of the container (15) to be sealed;
• b) means for feeding the tape (1, 16) between the notch (51) and the opening (21) of the container;
• c) means for relative motion along an axis of the notch (51) of the applicator head (50) or an axis of the opening (21) of the container (15) in either one direction when the notch is fitted closely on the opening (21) or in another direction when the applicator head (50) is displaced from the opening (21);
• d) means for feeding a succession of containers (15) and for positioning the containers one after another, the openings (21) of the succession of containers being coaxial or substantially coaxial to the notch (51) of the applicator head (50);
• e) first and second coils, wherein the tape (1, 16) is disposed on the first coil (52) and on the second coil (53);
• and
• f) the tape (1, 16) having a width greater than a corresponding dimension of the applicator head (50) and the applicator head (50) having edge corners parallel to longitudinal edges of the tape (1, 16), wherein lateral parts of the tape protruding over a smaller width of the applicator head are bent around the edge corners.
