Device and method for dispensing active ingredient-containing or active ingredient-carrying strips

A method for dispensing active ingredient-containing film or active ingredient-carrying film strips by a dispenser device (10) configured to dispense active ingredient-containing film or active ingredient-carrying film strips, having a housing (11), in which housing there is arranged a drive device (71) including an index coupling mechanism (72) and a wheel transmission (121), a spool chamber (12) configured to accommodate an active ingredient-containing or active ingredient-carrying film band (221), in which housing the wheel transmission (121) is mounted with an output roller (154) configured to convey the film band (221), and in which housing there is arranged a severing device (161) configured to sever the strips from the band (221),

• characterized in that,
• the wheel transmission (121) includes a drive wheel (122) having an external spur gear toothing (134) configured for engaging toothing of an intermediate wheel (151) for driving an output roller (154) configured to pull the active ingredient containing film or active ingredient-carrying film band (221),
• the indexing coupling mechanism (72) is positioned upstream of the wheel transmission (121),
• the indexing coupling mechanism (72) has a manually actuatable rotatable triggering element (91) axially mounted rotatably in the housing (11), the rotatable triggering element (91) has a plurality of driver lugs (113) which engage into and behind a hub (124), the drive wheel (122) is coupled by driver pegs (142) to a rachet wheel (81) of pot-shaped form, the ratchet wheel (81) is displaceable relative to the drive wheel (122) in the longitudinal direction, the ratchet wheel (81) has driver grooves (84) into which the driver pegs (142) of the drive wheel (122) engage, the ratchet wheel (81) has a base (83) averted from the rotatable triggering element (91) with an encircling sawtooth toothing (82) which engages into a corresponding counterpart toothing (45) of a bottom shell (31), between the base (83) and the drive wheel (122) there is arranged an indexing spring (73) in the form of a pressure spring configured to always push the base (83) of the ratchet wheel (81) and the drive wheel (122) apart, and
• the output roller (154) is driveable in incremental steps by the indexing coupling mechanism (72), wherein the active ingredient-containing or active ingredient-carrying film band (221) is arranged between the output roller (154) and the pressure-exerting roller (158), said method comprising the following steps:
• a manual actuation of the rotatable triggering element (91) triggers an indexing of the indexing coupling mechanism (72),
• the indexing of the indexing coupling mechanism (72) couples a movement of the rotatable triggering element (91) to the rotation of a drive wheel (122) in individual steps, such that the drive wheel (122) rotates through a defined angle of rotation,
• the drive wheel (122) transmits the rotational movement by the wheel transmission (121) to the output roller (154),
• the rotating output roller (154) conveys the band (221),
• the conveying of the band (221) by the travel that is dependent on the defined angle of rotation of the drive wheel (122),
• a strip is severed from the band (221) by manually actuating a rocker button (241) for actuating the severing device (161).
