A dispenser for dispensing a viscous material contained in a flexible package includes a body extending along a longitudinal axis that has a first end, an opposite second end, a cavity configured to receive the flexible package, and a handle assembly coupled to the first end. The handle assembly has a fixed handle, a trigger pivotally coupled to the fixed handle, and a rod extending between the fixed handle and the trigger into the cavity. A plurality of dispensing valves are positioned at the second end of the body and configured to dispense the viscous material, and a piston is movably disposed in the cavity for engagement with the flexible package. As the trigger is pivoted toward the fixed handle, the rod moves along the longitudinal axis toward the piston such that the piston engages the flexible package and the viscous material dispenses through the plurality of dispensing valves.

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.

The present invention is a material dispensing system for controllably dispensing material from a packaging such as a chub pack. The system can include a housing capable of receiving the packaging, a cover pivotably connected to the housing, at least one nozzle tip, and at least one piercing projection capable of piercing the packaging. A packaging compression assembly can be used to compress the packaging toward the piercing projection so that the piercing projection pierces the packaging and allows the material in the packaging to be dispensed from the nozzle tip. A locking slide can be included to secure the cover in a closed position.

Medical adhesive applicators are disclosed which allow medical adhesives to have long storage life and be easily dispensed in a controlled manner. In one embodiment, the applicator has a frangible glass vial with the medical adhesive. The frangible glass vial is held in a plastic enclosure with a dispensing tip. Attached to the plastic enclosure is a squeeze tube capable of imparting air pressure into the enclosure. To dispense medical adhesive quickly and with precision, one simply breaks the frangible glass vial and pushes on the squeeze tube. In another embodiment, the applicator has a proximal chamber containing medical adhesive, a distal chamber for dispensing medical adhesive and one or more rupturable membranes between them. To achieve long shelf life, the applicator chambers and membrane(s) are formed from fluorinated plastic. To dispense medical adhesive, one ruptures the membrane(s) and pushes on the sides of the proximal chamber.

An adapter couples to a single component fluid dispenser. The adapter includes a cap section, a first outlet, a second outlet, and a coupling member. The cap section has a cap interior surface that defines a cap channel extending therethrough. The first outlet defines a first outlet channel extending therethrough that is in fluid communication with the cap channel. The second outlet defines a second outlet channel extending therethrough that is in fluid communication with the cap channel. The coupling member is configured to couple the adapter to a nozzle.

The invention relates to a device for pressing out a material from a deformable tube, comprising the following: a housing having a base end; an upper section opposite the base end; and lateral wall sections between the base end and the upper section; a squeezer that can be introduced into the housing, wherein the squeezer has a carrier element and two opposing jaws for gripping and squeezing out a material from the tube, wherein the housing has an opening in the upper section through which an outlet of the tube can be guided, and same has openings in opposing parts of the lateral wall sections via which the jaws can be actuated, wherein the jaws are secured to the carrier element at one end and the squeezer also has a manual lever element on at least one jaw, wherein the lever element is connected to the jaw in a connection region to form an assembly, in which a pressure manually applied to the lever element brings about a force on the jaw in the direction of the other jaw, wherein the lever element has a body with reinforcing ribs, wherein the reinforcing ribs are surrounded at least partially by a closed outer skin, wherein a region of the outer skin forms a gripping region.

Bone cement applicators and methods apply a bone cement dough in the region of the spine. The applicators and method have at least one tubular cartridge with an internal space, containing starting components of the bone cement, at least one dispensing plunger that is mobile in longitudinal direction on the inside of the at least one cartridge, a hose, an application opening through which the bone cement dough is applicable, a three-way valve being arranged in the hose or on a side of the hose facing the at least one cartridge and in fluid connection with the opening of the at least one cartridge and/or a collecting container arranged on the three-way valve for accommodation of bone cement dough. The three-way valve is appropriately designed and/or arranged in the bone cement applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the at least one cartridge and closes a passage to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the at least one cartridge.

A dispenser (10) for dispensing flowable materials has a container (12) having an outer wall (20), a dividing wall (21) and a membrane (14) operably connected to define a first chamber (22), a second chamber (24) and a third chamber (16). The dividing wall (21) is connected to the membrane (14) at an interface (30). The first chamber (22) defines a first volume and is configured to contain a first flowable material (M1), and the second chamber (24) defines a second volume and is configured to contain a second flowable material (M2). The membrane (14) has a first section (34) having a first rupturable member (40) and a second section (36) having a second rupturable member (40). The first section (34) is separated from the second section (36) by the interface (30). The third chamber (16) is positioned adjacent the membrane (14) generally opposite the first chamber (22) and the second chamber (24), wherein the third chamber (16) defines a third volume and is configured to receive the first flowable material (M1) and the second flowable material (M2) upon rupture of the first rupturable member (40) and the second rupturable member (40) wherein a mixture (MX) is formed. The first volume and the second volume are collectively approximately equal to the third volume.

The invention relates to a metering device (100) for metering, in a manually-controlled manner, a light-curing material present in said metering device (100), the device comprising at least one reservoir (1) which can be deformed at least in some sections thereof and in which said light-curing material is contained, as well as a metering arrangement (3) for applying the light-curing material. The invention also relates to a kit and a method.

A discharge device can be used in a film package for storage of a one-component or multicomponent mass. The discharge device includes at least one receptacle for insertion of a film bag of the film package, and at least one piston disposed displaceably in the receptacle for discharging the mass from the film bag. The piston has a receiving groove for an accumulated film section of the at least partly emptied film bag.
