A closure device for a container has a lid member for closing the container opening, a chamber associated with the lid member and an inner housing, the chamber and the inner housing having closure means and opening means, which interact with one another in so that a medium contained in the chamber can escape into the container by moving the lid member relative to the inner housing. The chamber is divided by a separating part into a first partial chamber and a second partial chamber, that are arranged one behind the other. A first medium can be received in the first partial chamber and a second medium can be received in the second partial chamber, and by moving the separating part into open position, the first and the second medium can be mixed in the chamber, and the mixed medium can emerge into the container by moving the lid member.

A container containing a concentrate for dialysis includes a pouch or cartridge containing a solid concentrate of constituents for the dialysis solution, the pouch or cartridge being closed by a connector having a filling channel extending completely through the connector, which is for filling the pouch or cartridge with the solid concentrate, means for introducing a solution-forming liquid into the pouch or cartridge and for extracting the solution obtained, these introduction and extraction means having at least one connecting portion for connecting them to a corresponding port of the dialysis machine. The filling channel is closed by a stopper which has a reservoir containing a second constituent or group of constituents for the dialysis solution, and means for producing an outlet opening in the reservoir contacting the inside of the reservoir with the side of the stopper located in the container.

This container lid fits onto existing insulated cups. It has a refillable and sealable reservoir with a top opening to receive substances and a bottom opening to release substances into a container. The release of substances is controlled and measured before release. A double piston and button combination interact with a narrow section of the reservoir to dispense only a portion of the contents from the reservoir into the container. The released portion is carefully metered within the narrow channel when the double piston alternately seals a first opening and a second opening of the narrow channel. The reservoir serves to store the unreleased substance until the next time the button is activated to release addition substance into the container.

This container lid fits onto existing insulated cups. It has a refillable and sealable reservoir and in the preferred embodiment includes a top opening to receive substances and a bottom opening to release substances into a container. The release of substances into the beverage container is controlled and is measured before release. A preferred double piston and button combination interact with a narrow section of the reservoir to dispense only a portion of the contents from the reservoir into the container. The released portion is carefully metered within the narrow channel when the double piston alternately seals a first opening and a second opening of the narrow channel. The reservoir serves to store the unreleased substance until the next time the button is activated to release addition substance into the container.

The present invention provides an instant-mix cap, which relates to the technical field of the bottle cap. The instant-mix cap includes a cap body and a sealing plug, and the cap body and the sealing plug enclosed to form a sealed storage chamber, a pushing part can drive an elastic part to deform and move downward under the action of an external force, and a pillar simultaneously pushes the sealing plug to move downward, so that the sealing plug is forced to be disconnected from a bottom of a cap cylinder, thereby opening the storage chamber.

Mixing stopper, fixed on the neck of a package which includes a capsule for anchoring to the neck of the package, a receptacle containing a product to be mixed with the content of the package, a lid for closing the open base of the receptacle and a spring fitted between the receptacle and the bottom of the capsule.

A container for use in growing, culturing and/or modifying cells has a primary container (10) and defines an internal lumen in which a wall element (8) of the primary container (10) is compressible, and wherein the container has an auxiliary container (16) in fluid communication with the primary container (10). The fact that the device has an auxiliary container 16 allows a number of separate reactions to be carried out within a single container.

Polymorphic forms of 3-(4-amino-1-oxo-1,3 dihydro-isoindol-2-yl)-piperidine-2,6-dione are disclosed. Compositions comprising the polymorphic forms, methods of making the polymorphic forms and methods of their use are also disclosed.

A closure device for a container comprising a cover element for closing the container, a chamber arranged on the cover element and an inner housing. The chamber has a chamber end piece having an outlet opening that can be closed by means of a closure means. The inner housing comprises opening means for opening the outlet opening, wherein the chamber can be moved relative to the inner housing from a closed position into an outlet position. The chamber and the chamber end piece are connected to each other in a fluid-tight and gas-tight manner by means of a plastic seal injection molded on chamber and chamber end piece, wherein chamber, chamber end piece and plastic seal are formed from the same plastic. The invention further relates to a method for producing a closure device or a chamber.

Described is an automated reagent dispensing cap and methods of use in an automated clinical analyzer for introducing one or more reagent components housed in the reagent dispensing cap into a container enclosing another reagent component with which it is combined to achieve a reagent useful for diagnostic testing.
