A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

A dental-impression-material electric dispenser includes a main body having a longitudinal mounting portion formed therein. A top-open tray part includes, at the front end thereof, extrusion ports communicate with a mixing tip part communicate with each other. An impression material cartridge, having partitioned a first filling chamber and a second filling chamber, is mounted. The mixing tip part communicates with a pair of extrusion ports formed at the front end of the impression material cartridge, and stirs and discharges a silicone base and a curing agent, each being discharged in a fixed amount through the pair of extrusion ports. An extrusion rod part simultaneously presses a pair of pistons of the impression material cartridge mounted on the tray part through a pair of pressing ends. An electric extrusion part receives starting current from a battery cell and allows the extrusion rod part to advance forward through electrical driving.

A repair kit for use in repairing damaged portions of a surface or adhering objects and methods of using the repair kit are described herein. The repair kit comprises a housing having a first end and as second end, packaging in the form of a sealed container enclosing a resin component and a reactive component that react to form a polymeric composite material when mixed, a dispensing cap configured to engage with the first end of the housing and a pusher configured to engage with a second end of the housing. The sealed container includes a first removable divider engaged with the sealed container in a manner to form and create a first compartment and a second compartment. The polymeric composite material of the repair kit may be used as an adhesive, as a filler or sealant to repair damaged surfaces, pavements, walls, and wooden materials, and as a coating.

A system for storing and dispensing a flowable multi-component composition contains a coaxial cartridge and a support structure. The coaxial cartridge has a hollow-cylindrical inner wall, a outer wall arranged coaxially around the inner wall, an inner chamber for a first component that is delimited radially by the inner wall, an outer chamber for a second component that lies radially between the inner wall and outer wall, and a front wall which firmly closes the two chambers on an end face of the cartridge and has a dispensing opening in each chamber. The support structure is designed to receive and hold the cartridge, and has a side wall shaped like a tube portion. An inner diameter of the side wall is varied or can be adjusted in the axial and/or radial direction of the support structure, adjusted when the cartridge is inserted and removed, or adjusted during the pressing-out process.

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

A cartridge for a one or two-component mixing and dispensing system includes at least one flexible film bag as a cartridge wall, a rigid front part that is in particular integrally formed with the at least one flexible film bag and that is arranged at a front end section of the at least one film bag, the rigid front part including at least one outlet opening. The cartridge for a two-component mixing and dispensing system has a first flexible film bag as a cartridge wall and a second flexible film bag as a cartridge wall, and a structure surrounding the cartridge.

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

The present disclosure relates to a metering and mixing device including a cartridge holder (1) and a cartridge (2). A surface-to-surface, and also positive and non-positive connection exists between the cartridge and the holder. The present disclosure also relates to a method for coating substrates with two- or multicomponent coating media, in which the metering and mixing device is used.

The invention relates to a measuring and mixing device including a cartridge holder (1) and a cartridge (2), a flat, at least form-fit connection being mounted between the cartridge and the cartridge holder. The invention also relates to a method for coating substrates with two or multi-component coating agents, in which the measuring and mixing device is used.

A compressible cartridge includes a first flexible bag, a second flexible bag, and a rigid face plate. The first and second flexible bags include a multilayer film having at least three layers formed from different materials. The first and second flexible bags have a front end and a sealed back end opposite the front end. The first flexible bag defines a first volume to receive a first flowable material. The second flexible bag defines a second volume to receive a second flowable material that is different from the first flowable material. The rigid face plate has a first collar, a second collar, and a nosepiece. The first collar is bonded to the front end of the first flexible bag, and the second collar is bonded to the front end of the second flexible bag. The nosepiece defines 1) a first opening that is in fluid communication with the first volume of the first flexible bag, 2) a second opening that is in fluid communication with the second volume of the second flexible bag, and 3) a discharge opening.
