The present invention relates to a capsule (11) for diffusing a substance in a liquid within a receptacle (50). The capsule comprises an expandable element and, in a first state the capsule has a first width and in a second state the capsule has a second width. The width of the capsule in the second state is greater than that of the first state.

A metering and mixing device contains a multichamber cartridge and a cartridge holder having a reception container for the multichamber cartridge and a compressed air connection and a connection for an application device. The reception container has an internal tube arranged coaxially to the walls of the cartridge holder and equipped with static mixing elements. The multichamber cartridge contains an upper portion having a directional valve, a middle portion configured as a tubular empty space surrounded by at least two chambers arranged tubularly in the direction of the longitudinal axis of the cartridge, and a lower portion having a piston for each chamber. The multichamber cartridge is arranged in the cartridge holder such that the inner wall of the inner tube of the multichamber cartridge bears, leak-tight, against the outer wall of the tube of the cartridge holder.

A blender system includes a blender and container. The blender includes a bottle including a blending chamber with a bottle opening and a shoulder about the bottle opening, and a lid configured to couple with the bottle and that includes a container receiver. The container includes a nutrient receptacle to receive contents with a closed end and a receptacle opening opposite the closed end, a lip about the receptacle opening, and at least two flaps coupled to the lip via a lip hinge and positioned to cover a portion of the opening. Coupling the lid to the bottle with the container in the container receiver presses the lip towards the closed end so that the at least two flaps are pushed open to discharge the contents into the blending chamber.

Varied embodiments of a container/dispenser having a multi-chamber bellows member having a plurality of collapsible bellows chambers allowing more than one substance to be contained within the container and simultaneously dispensed when a sufficient axial force is exerted on a platform to compress the bellows member forcing flowable materials from each chamber. In an alternative embodiment, the present invention discloses a retrofit multi-chambered bellows container, which may be adapted to a standard caulking tube container.

Magnetic stir bar (1) for use with a magnetic stirrer, said magnetic stir bar (1) comprising at least one permanent magnet (2) for spinning said magnetic stir bar (1) when said magnetic stir bar (1) is subjected to a rotating magnetic field; and a chamber (3) for storing a product inside said magnetic stir bar (1), wherein said magnetic stir bar (1) has a closed configuration in which said chamber (3) is closed, said magnetic stir bar (1) being maintained in said closed configuration under the effect of a first force (f), and an open configuration in which said chamber (3) is open, said magnetic stir bar (1) being maintained in said open configuration under the effect of a second force (F); and wherein said magnetic stir bar (1) is adapted to automatically reconfigure itself from said closed configuration to said open configuration when said magnetic stir bar (1) is spun at or above a threshold rotational speed (t).

A combination plunger, a mixing device and a mixing syringe including the same are provided. The mixing syringe includes concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. The combination plunger includes a mixing plunger and a delivery plunger and a biasing means. The mixing plunger is slidably located in the outer chamber and translated by coordinated depression of the delivery plunger to transfer a first substance from the outer chamber to mix with a second substance in the inner chamber. After the mixing stage is complete, the delivery plunger is disengaged from the mixing plunger and permitted, such as by rotation, to be further depressed in the axial direction to deliver fluid contents of the mixing syringe to a recipient. The mixing syringe needle is then retracted as result of engagement by the delivery plunger and activation of the biasing means.

A capsule for mixing substances includes a chamber having first and second ends. A piston is fitted in the chamber. The piston has a proximal end facing the first end, and a distal end facing the second end. A mixer element is arranged within the chamber between the piston and the second end. The mixer element is disposed at a distal end of a mixer rod. The piston has an aperture through which the mixer rod passes. The piston and mixer element are separately displaceable relative to the first and second ends and relative to each other. The piston includes a plurality of cavities within the piston, such that one cavity is separated from another cavity and filled with a different ingredient substance.

A liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are contained in the chamber. The first conduit connects the chamber to an outlet port in the container where the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an existing flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.

An integrated at least two component mixing and delivery system and method for creating a new mixture from a first component contained within a first enclosure and a second component contained within a second enclosure that is contained within the first enclosure and, via a series of operations that mix the two components and enable the application of through an applicator tip the placement of the new mixture on at least one surface or a portion thereof.
