    • The invention relates to an electric handheld tool having a cover (2) that can be removably fastened to the spindle neck and that can rotate at least partially about an axis parallel to the spindle axis (54) or in line with the same, acting together with a counter-catch (30) on the spindle neck for preventing rotation by means of a spring-loaded catch (26) on the cover (2) in different rotary positions, wherein the cover (2) can be slid onto the spindle neck and then brought into a rear grip position, wherein the catch (26) can be deflected in the axial direction of the spindle axis (54) on the cover in a spring-loaded manner, and the counter-catches (30) are provided on the axial end face (32) of the spindle neck, wherein a stop (70) acts together with the catch (26) in a first position and limits the axially spring-loaded deflection of the catch (26), such that the catch (26) and counter-catch (30) are held in engagement, and releases the axial deflection in a second position such that the catch (26) and the counter-catch (30) are out of engagement and can rotate relative to each other.

    • The present invention is preferably directed to a dispenser of the type sold by 3M ESPE under the trade name Pentamix and as also described above. Such a dispenser preferably comprises at least a first and a second compartment for a first reservoir and a second reservoir, respectively, the first and the second reservoirs containing a first and a second component for the dental material, respectively. It further preferably comprises a first and a second plunger driven by a first drive for advancing the first and the second components from the first and the second reservoirs, respectively. Moreover, a dynamic mixer driven by a second drive for automatically mixing the first and second components to form the dental material from the first and second components is provided. Such a dispenser further preferably has a dispensing portion or mixing tip for dispensing the mixed dental material. The present invention is more particularly directed to a dispenser or method adapted for advancing and mixing at least one dental material, comprising at least one drive which is operated on a predetermined, non-uniform drive speed profile. Preferably an advancing speed profile is provided for advancing the components and/or a mixing speed profile is provided for mixing the components, and either profile may be a "drive speed profile" as that term is used herein. More preferably both profiles are provided.
    • 本发明优选地涉及由3M ESPE以商品名Pentamix出售的类型的分配器,并且还如上所述。 这种分配器优选地分别包括用于第一储存器和第二储存器的至少第一和第二隔室,第一和第二储存器分别包含牙科材料的第一和第二部件。 它还优选地包括由第一驱动器驱动的第一和第二柱塞,用于分别从第一和第二储存器推进第一和第二部件。 此外,提供了由第二驱动器驱动的动态混合器,用于自动混合第一和第二部件以从第一和第二部件形成牙科材料。 这种分配器还优选地具有用于分配混合牙科材料的分配部分或混合尖端。 本发明更具体地涉及一种适于推进和混合至少一种牙科材料的分配器或方法,包括至少一个在预定的非均匀驱动速度曲线上操作的驱动器。 优选地,提供用于推进部件的前进速度曲线和/或提供用于混合部件的混合速度曲线,并且两个轮廓可以是本文使用的术语“驱动速度曲线”。 更优选地,提供两个轮廓。
