The invention provides a method and an apparatus for discharging a substance contained in a cartridge or the like from the cartridge. The substance is prevented from flowing out by a sealing member provided at the outlet of the cartridge. To open the cartridge, a relative displacement between the cartridge and a coupling member mounted on the connection piece of the cartridge is effected to thereby open the sealing member by way of a cutting member provided in the coupling member. The sealing member is opened at least to such an extent that it releases the flow path of the substance contained in the cartridge fully or partially due to the pressure exerted on the sealing member by the substance contained in the cartridge during an initial phase of the discharge operation.

Method of discharging a substance from a cartridge and an apparatus for

A manually guided electrical tool which is driven by a drive motor. The tool includes a device for metering and mixing at least two substances and for the feeding of the intermixed substances to a treatment place. The device includes: cartridges which contain the substances to be intermixed, receptacle pockets for receiving the cartridges, an extruding means associated with each cartridge for extruding the substances; a mixer for mixing the extruded substance which has an outlet through which the intermixed substances are fed, a feed duct connected to a each cartridge for transporting the extruded substances to the mixer, a gear unit driven by the drive motor, a drive element driven by the gear unit for activating the extruding means and the mixer; and a gear housing for housing the gear unit which is attached to the drive motor.
