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),

• the 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 film or active ingredient-carrying film band (221), in which housing there is mounted a wheel transmission (121) with an output roller (154) configured to convey the band (221), and in which housing there is arranged a severing device (161) configured to sever the strips from the band (221) and a dosing device (231),
• characterized in that,
• the wheel transmission (121) includes a drive wheel (122) having a pot-shape having an internal toothing (133) and an external toothing (134), the internal toothing (133) includes driving detent teeth (135), the external toothing (134) configured for engaging with toothing of an intermediate wheel (151) for driving an output roller (154) configured to pull the active ingredient-containing 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 triggering element (91) mounted on a housing journal (32), the triggering element (91) having a grip lever (101) and a blade holding lever (102) between which is arranged a pivot bearing (103), the triggering element (91) having in the grip lever (101) a detent guide (104) arranged radially with respect to a pivot axis (23), the triggering element (91) having a detent element (106) protruding therefrom in the direction of a housing bottom part (31), the detent guide (104) having a pressure spring (105) arranged therein for exerting a centrifugal load on the detent element (106) with respect to the pivot axis (23), the detent element (106) for operatively engaging the internal toothing (133), the blade holder lever (102) having a driver peg (111) operatively extending therefrom coupled to a pivot frame (171) of the severing device (161) configured to actuate the severing device (161),
• the output roller (154) is driveable in incremental steps by the indexing coupling mechanism (72),
• the dosing device (231) including a dosing lever (232) mounted on the housing journal (32) and arranged behind the triggering element (91), the dosing lever (232) having a dosing slide (233) protruding from the housing (11), at an end averted from the dosing slide (233) the dosing lever (232) having a guide shell (234) for supporting the detent element (106) upon initial actuation of the trigger element (91) within a limited rotational range, the guide shell (234) operatively arranged in the drive wheel (122) such that upon the detent element (106) departing from an end of the guide shell (234) the detent element (106) engages a detent tooth space (136) of the internal toothing of the drive wheel (122), wherein the drive wheel (122) configured to drive via the intermediate wheel (151) the output roller (154) for conveying the band (221) in a conveying direction (225),
• wherein the active ingredient-containing film or active ingredient-carrying film band (221) is arranged between the output roller (154) and a pressure-exerting roller (158), said method comprising the following steps:
• a manual actuation of the 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 triggering element (91) to the rotation of the drive wheel (122), 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) releases the severing device (161),
• a strip is severed from the band (221) by the severing device (161).
