Title: Destructible cartridge for multicomponent masses
Inventor: LANG GUSZTAV DR DIPL ING
IPC: C09J11/00
Filed: 1985-03-07
Granted: 1988-03-31
Abstract: A destructible container is arranged to maintain the components of a multi-component settable mass in separate regions until they are ready to be mixed for anchoring a fastener member in a borehole. The container is made up of an elongated outer cartridge and an inner cartridge positioned within the outer cartridge so that a space for one of the components is formed between the inner cartridge and the outer cartridge. The multi-component mass includes a resin component filled into the outer cartridge and a hardenable component filled into the inner cartridge. The space within the outer cartridge is divided into two separate regions, preferably one following the other in the elongated direction of the outer cartridge. The resin component is present in each region, however, a thixotropic agent is included in one region but not the other so that the viscosity of the resin component is greatly increased within the one region. Preferably, the increased viscosity is present in the region of the outer cartridge forming the trailing end of the container when it is inserted into a borehole so that flow out of the borehole is, for practical purposes, prevented. Accordingly, a resin component which is highly fluid prior to the mixing operation, such as methylmethacrylate (MMA) can be used.
