Storage and mixing systems for pasty two-component polymethyl methacrylate bone cements comprise a tubular cartridge having a cylindrical inner chamber, a cartridge head, which closes one end of the tubular cartridge at the front side, a partition that is disposed axially in the cylindrical inner chamber of the cartridge. The partition divides the cylindrical inner chamber of the cartridge bounded by the cartridge head into two cavities that are spatially separated from one another, wherein a first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity. The systems further comprising two dispensing plungers axially displaceable in the two cavities of the cartridge, wherein the dispensing plungers close the two cavities on the back side of the cavities situated opposite the cartridge head, a bending device for deforming the partition, wherein the bending device is axially movable in the cartridge and is disposed, or is to be disposed, behind the dispensing plungers, as seen from the cartridge head, wherein the bending device has a deflection surface that is inclined with respect to the axis of the cartridge and pushes the partition laterally in the direction of the inside wall of the cartridge when the bending device is pushed into the cartridge.

A storage and mixing system, for pasty two-component polymethyl methacrylate bone cements, comprises a cartridge with a cylindrical interior, a cartridge head that closes an end of said cartridge, a partition wall axially disposed in the cylindrical interior of the cartridge, wherein said partition wall is connected to the circumferential surface of the cylindrical interior of the cartridge and divides the cylindrical interior of the cartridge delimited by the cartridge head into two spatially separate cavities. The first cavity includes a first pasty cement component and the separate second cavity includes a second pasty cement component, two delivery plungers close the two cavities on the side of the cavities opposite the cartridge head. At least two cutting edges are disposed on the front side of the sleeve-shaped connecting means facing the cartridge head, such that the at least two cutting edges cut off the partition wall from the cylindrical inner wall of the cartridge as at least one cut-off strip when the delivery plungers are advanced towards the cartridge head in the cavities with the connecting means, and wherein the sleeve-shaped connecting means comprises a deflecting surface which is inclined to the axis of the connecting means which, on advancing the connecting means, presses the at least one cut-off strip of the partition wall towards the inner wall of the cartridge.

A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge with a cylindrical interior, a cartridge head that closes one end of the tubular cartridge, a partition wall axially disposed in the cylindrical interior and dividing the cylindrical interior into two spatially separate cavities, the first cavity including a first pasty cement component and the second cavity including a second pasty cement component, two delivery plungers disposed movably in the two cavities and connected via a connecting means, wherein a wedge or cone having a cutting edge on the front side thereof facing the cartridge head is disposed on the connecting means, such that said cutting edge cuts open the partition wall when the delivery pistons are advanced towards the cartridge head and the wedge or cone presses the cut open parts of the partition wall towards the inner wall of the cartridge.

A side by side cartridge assembly for dispensing first and second fluid materials includes a first cartridge container and a second cartridge container. The cartridge containers include respective bodies and nozzle members coupled with the bodies. The cartridge containers are positionable with respect to one another such that the two nozzle members cooperate to form a cartridge outlet for dispensing first and second fluid materials from the respective bodies. The cartridge outlet includes dispensing openings communicating with respective nozzle channels, and a sealing surface configured for sealing engagement with a mixing element when a mixing element is attached to the cartridge outlet.

A gluing device includes a glue tube, a connector, a needle unit, and a locking element. One end of the connector is connected to a glue outlet of the glue tube, other end of the connector is connected to a glue inlet of the needle unit. The locking element is sleeved on a connection part of the connector and the needle unit. The needle unit is connected to the connector by the locking element and allows detachment. The glue tube, the connector, and the needle unit together form a glue channel in the gluing device. The connector and the locking element make detachment and assembly of the needle unit on the glue tube easy and simple, even though a diameter of the needle unit is very small.

A cartridge for a material to be dispensed includes a rigid head part having a dispensing outlet and a flexible film forming a cartridge wall, with the flexible film bounding a cartridge chamber for the material to be dispensed, extending at least partially in a longitudinal direction of the cartridge and having a front end that is connected to the head part. The head part has an outer circumferential surface, and an inner surface of the front end of the flexible film is sealingly and non-releasably connected to the outer circumferential surface of the head part.

An applicator for dispensing a viscous material from a container. The applicator comprises a nozzle for fluid communication with the container. The nozzle has an outlet at a first end and base in proximity to an opposed second end. The nozzle further includes a support arm spaced apart from the nozzle. The support arm and the nozzle collectively forming a slot therebetween for releasably receiving a blade. An attachment portion extend from the base and is configured to releasably engage the container to permit material within the container to flow under pressure through the nozzle and onto a surface. When the blade is received within the slot, it contacts the material as it exits the nozzle and assists in forming the material into a desired shape or configuration.

A paint dispenser which, when pushed against a surface, releases a metered amount of phosphorescent paint or fluorescent paint in sufficient quantity to simulate a single star when room lighting is turned off. The pump is mounted to a common handle by screw-on means so that an operator's reach is extended from normal standing height to a height sufficient to contact the ceiling with the depositor.

A cartridge for a material to be dispensed includes a rigid head part having a dispensing outlet and a flexible film forming a cartridge wall, with the flexible film bounding a cartridge chamber for the material to be dispensed, extending at least partially in a longitudinal direction of the cartridge and having a front end that is connected to the head part. The head part has an outer circumferential surface, and an inner surface of the front end of the flexible film is sealingly and non-releasably connected to the outer circumferential surface of the head part.

A cap for receiving over an end of a flexible tube or chub. The cap comprises a hollow body member having a downwardly depending skirt and an opening through which material from within the flexible tube or chub can be extruded. Within the hollow body member is a hollow compartment that is in part defined by the skit and that receives the flexible tube or chub with the skirt sealingly received thereabout. Within the hollow compartment there is situated a plurality of cutters configured to pierce the flexible tube or chub upon compressing the flexible tube or chub into the cap. Upon the piercing of the flexible tube or chub, compressive force applied to the flexible tube or chub causes material therein to flow into the hollow compartment and through the opening.
