Abstract: A packaging (100, 200) for storing a free-flowing, paste-like or powdery substance (110), includes a bottom foil (120, 220) and a covering foil (130, 230) which are sealed to each other at least in certain portions, and a removal chamber (140, 240) which is formed from regions of the bottom foil and the covering foil that are detachably sealed to one another at least in certain portions, wherein the removal chamber can be opened by detaching at least a first portion (131, 231) of the covering foil from the bottom foil, wherein a second portion (132, 232), which is arranged adjacent to the first portion, of the covering foil displays less deformation resistance than the first portion of the covering foil, so that plastic deformation, required for opening the removal chamber, of the covering foil occurs substantially in the second portion of the covering foil.

Abstract: A syringe (1) for dosed dispensing of material, in particular of free-flowing and/or pasty dental material, includes a sleeve (10) for accommodating material and a piston (15) which can be inserted into the sleeve (10) and which has a piston member (15?), a frictional engagement element (25) which abuts an inner wall (35) of the sleeve (10), and an elastic element (30) coupling the frictional engagement element (25) and the piston 10 member (15?), wherein the sleeve (10) and the piston (15) inserted into the sleeve define an inner sleeve chamber (70) for accommodating the material, wherein the elastic element (30) can be tensioned, on insertion of the piston (15) and/or of the piston member (15?) into the sleeve (10), by means of a relative lag of the frictional engagement element (25) in relation to the piston member (15?), 15 wherein by relaxing the elastic element (30) it is possible for the piston member (15?) to be expelled at least partially from the sleeve (10) while the frictional engagement element (

Abstract: A syringe for dosed dispensing of material, in particular of free-flowing and/or pasty dental material, includes a sleeve for accommodating material and a piston inserted into the sleeve defining an inner sleeve chamber and which has a piston member, a frictional engagement element which abuts an inner wall of the sleeve, and an elastic element coupling the frictional engagement element and the piston member, wherein the elastic element can be tensioned, on insertion of the piston and/or of the piston member into the sleeve, by means of a relative lag of the frictional engagement element in relation to the piston member, wherein by relaxing the elastic element it is possible for the piston member to be expelled at least partially from the sleeve while the frictional engagement element remains motionless, to increase the volume of the inner sleeve chamber.
