Abstract: The active-substance support consists of a rectangular film or sheet (1) of a thermoplastic material which, at its upper end, comprises a T-shaped head piece (2) of which the symmetrically arranged hook-like side arms (3,4) can be bent downwards at a right angle along folding lines (5,6) extending parallel to the longitudinal direction. When needed, the initially flat side arms (3,4) are bent downwards at a right angle and hung on the honeycomb frame so that the active-substance strip (1) is kept centrally suspended in a honeycomb passage.

Abstract: The tube has a peg-shaped neck extension (3) at its upper end, which contains a predetermined breaking point (4). The neck extension (3) is generally positioned under the removable protective cap (7). A short socket (9) is formed on the upper side of the cap (7) in an axial direction, the interior diameter of which is slightly greater than the diameter of the neck extension (3). The inner surface of this socket (9) and the outer surface of the neck extension (3) are provided with corresponding notch flanges (5) or notch grooves (10), such that the cap (7) and the neck extension (3) are non-positively connected to each other when rotated about the longitudinal axis, when the cap (7) with the socket (9) is positioned on the peg-shaped neck extension (3). If the cap (7) is rotated in this position about the longitudinal axis with slight pressure simultaneously exerted then the peg-shaped neck extension (3) is sheared off at the predetermined breaking point (4) and the tube is thereby opened.
