FIELD: manufacturing technology.SUBSTANCE: invention relates to cartridge and can be used in industrial sector, in construction, for example, buildings, in dental field. Cartridge contains at least one receiving chamber (2) passing in longitudinal direction for medium intended for discharge, cartridge end side (4) and wall (3). End side (4) and wall (3) limit receiving chamber (2) and are integrally molded under pressure. End side (4) has outlet for medium. Cartridge wall (3) on its inner side limiting receiving chamber (2) has first film (6), which passes along entire cartridge wall (3) and permanently connected to cartridge wall (3). In method of cartridge making in casting under pressure device tool rod is provided, which is former for cartridge receiving chamber (2). On rod side surface film (6) is applied, which is then filled with liquid polymer material. Multi-component cartridge contains at least two cartridges. Both cartridges in longitudinal direction are located in each other, preferably coaxially in each other so, that one cartridge surrounds another cartridge.EFFECT: technical result of group of inventions consists in improvement of environmental stability and environmental protection, as well as enabling high functional reliability and good cartridge applicability for storage.15 cl, 9 dwg |
