A device for dispensing fluid products includes one or more containers, each storing one fluid product, a unique pump provided with a dosage chamber enclosing a dose of mixture of the fluid products, and including an actuating member, and a manifold associating the pump to the containers for dispensing the fluid products. The manifold includes one or more hollow tubes each extending into a container and forming a channel for the flow of the fluid product from the container towards the pump. As well, the tubes of the manifold are rigid and at least one tube of the manifold includes means for regulating the volumetric ratio of the fluid product flow, these regulating means being integrated inside the rigid tube.

The present invention relates devices capable of continuous and simultaneous expression of components of a multi-part biomedical composition with variable mixing ratios. The device has at least two syringes that contain the inter-reactive components of the multi-part biomedical composition. At least the barrel of the first syringe has a first retention compartment having a cross-sectional area dimension that is larger than the cross-sectional area of a second retention compartment. The first piston has a cross-sectional dimension that matches the inside cross-sectional dimension of the small dimensioned retention compartment, while a ring-shaped gasket is located within the large dimensioned retention compartment and has an outside cross-sectional dimension that matches an interior dimension of the large dimension retention compartment.

A dispenser for applying at least two compositions, the dispenser including at least two reservoirs for storing the at least two compositions separately, at least two pumps for pumping the at least two compositions, which pumps have different strokes, an exit orifice, and an actuator assembly. The difference between the first stroke and the second stroke is accommodated through flexure of a flexing member in the actuator assembly. The first composition includes microcapsules and the second composition includes a volatile solvent.

An application dispenser for at least one component, in particular for an adjustable dosing and/or mixing dispenser, includes a rotation element, in particular a ball for applying the at least one component, and a pump configured to load the at least one component with pressure and feed the at least one component under pressure onto the rotation element.

A process for flushing a dispenser and a process for combining a first composition and a second composition to form a mixture and dispensing said mixture through an exit orifice are provided; assemblies for flushing are also provided.

A dispenser includes a housing defining an internal volume. A cartridge is coupled with the housing. A tube extends into the internal volume of the housing. A first liquid is drawn from the internal volume into the tube through a first inlet in the tube when the pump assembly is actuated. A connecting member is positioned in the internal volume of the housing and coupled to the cartridge and the tube. A second liquid is drawn from the cartridge, through the connecting member, and into the tube through a second inlet in the tube when the pump assembly is actuated.

Described herein is a fluid dispensing device that enables rapid fluid mixing of separate solutions prior to dispensing. Also described herein are methods of using and manufacturing the fluid dispensing device. The fluid dispensing device is useful with a variety of reactive and/or concentrated formulations, including cleaning formulations.
