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 storage and mixing device includes a mixing compartment, two pistons that each extend from the mixing compartment and end in a displacement section, each piston defining a passageway having a first opening communicating with the mixing compartment and a second opening communicating with an inlet at the displacement section, and a housing having two piston guides and a cartridge compartment connected to the piston guide, each piston guide slidably receiving one of the pistons, and each cartridge compartment receiving a removable cartridge that includes a cavity for containing separate substances and an opening sealed by a cartridge seal. The displacement section of each piston includes a piercing member for piercing the cartridge seal of the cartridge arranged in the corresponding cartridge compartment, such that the displacement section enters the cartridge cavity and displaces the contained substance into the mixing compartment via the inlet and the passageway.

An adapter for an airtight connection to a container and for airtight dispensing of the container's contents, the adapter having: a gate valve, a tube extending from the gate valve to a female coupling, the female coupling being configured for insertion in a mouth of the container, the female coupling having a dispensing valve for opening when dispensing the container's contents and closing when dispensing is finished as needed, such that air is prevented from entering the container, and an airtight connector for connecting the adapter to the container.

A carbonated beverage maker includes a water reservoir, a carbon dioxide creation chamber, and a carbonation chamber. The water reservoir holds ice water and has a first impeller and a shroud surrounding the first impeller. The carbon dioxide creation chamber contains chemical elements and receives warm water. The chemical elements react with each other to create carbon dioxide when the warm water is introduced to the carbon dioxide creation chamber. The carbonation chamber is connected to the water reservoir and the carbon dioxide creation chamber. The carbonation chamber has a second impeller that includes a stem portion and blades. The stem portion and the blades define conduits therein. The blades create a low pressure region in a lower portion of the carbonation chamber such that carbon dioxide from the carbon dioxide creation chamber flows through the conduits to the low pressure region.

A powder transfer bag includes a balloon or a membrane sealing its mouth. A connector to be used with the bags allows the bag to connect to a hydration device. A method of hydrating material in a powder transfer bag is provided.

The disclosure is directed to a drink container that includes a lower container having a void formed therein configured to hold a liquid, a divider disposed in the void of the lower container, the divider configured to form a plurality of compartments, each compartment being configured to separately hold a liquid, wherein each of the compartments has an open top portion, a film configured to seal the top portions of each of the plurality of compartments, a upper container configured to interact with the lower container and a cutter, the cutter being operably attached to an internal surface of the upper container at a first end, wherein a cutting edge of the cutter is nearer the film than the first end of the cutter.

An instant cosmetic preparation device includes: a housing; a finished product container transfer part which is configured to transfer to a finished product container filled with a cosmetic mixture stored inside the housing to a sealing position; a sealing part which is arranged inside the housing; and a control unit which is arranged inside the housing for controlling the operation of the sealing part to seal an open injection port of the finished product container.

A container system having connection devices for establishing a fluid connection between the containers. In one aspect, a connection device comprises a thin point that, within its shape, has a tip between two at least substantially straight legs and wherein the other connection device has a ram with a splitting device that is designed and arranged such as to rupture said thin point by acting on the tip when the containers are coupled. In another aspect, the thin point surrounds the ram, and in a third aspect the connection devices have corresponding, similar thin points, closure elements and splitting devices. In further aspects, the connection devices are similar, and the connection devices are linearly guided.

A liquid concentrate generation system may comprise a manifold having an inlet receptacle including a first piercing member, an outlet receptacle including a second piercing member, and a flow channel connecting the inlet receptacle and outlet receptacle. The system may further comprise a cartridge having an inlet port and an outlet port sealed by a respective first and second cover. The inlet and outlet port may be respectively configured to displace within the inlet receptacle and outlet receptacle from an unspiked position to a spiked position. First and second piercing members may be in communication with the flow channel and spaced apart respectively from the first and second cover in the unspiked position. The first and second piercing members may be isolated from the flow channel and may respectively puncture the first and second cover in the spiked position.

A container for bone cement includes a first member defining a chamber, which contains a first ingredient. The chamber also includes a second member movably coupled to the first member. The second member includes a mixing device that is movably disposed within the first chamber, and the second member defines a second chamber containing a second ingredient. The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.
