Device for preparing a cosmetic composition, set of capsules and associated preparation process The invention relates to a device (10) for preparing a cosmetic composition comprising: —a structure (28) defining a housing (30) extending along a longitudinal axis (X-X′), —a piston (36) movable in translation in relation to the structure (28) along the longitudinal axis (X-X′) in the housing (30), and —an outlet nozzle (32) opening at one end of the housing (30), suitable for being fluidically connected to a receptacle. The housing (30) receives removably a plurality of capsules (16) aligned coaxially along the longitudinal axis (X-X′), at least one of the capsules (16) containing at least one constituent of the cosmetic composition (12). The piston (36) is mounted movable through the capsules (16) to successively perforate each capsule (36) and convey contents of each capsule (16) to the outlet nozzle (32).

A water bottle system for adding an additive, which may be flavoring, to the line of flow without contaminating the main reservoir. The system may include a water bottle with a lid feature that may maintain a flavor that may be infused into the water within the water bottle. The infusion of the additive may be adjusted by a user to have the desired concentration of additive to a user’s liking. The additive cartridge may be reusable or disposable depending on a user's preference.

One aspect relates to a method for providing a bone cement from two starting components, having a hollow cylinder-shaped first container, in which a monomer liquid as first starting component can be stored, a hollow cylinder-shaped second container comprising a container wall, a first internal space, and a second internal space, whereby a bone cement powder as second starting component can be stored in the first internal space, and whereby the monomer liquid can be conveyed into the second internal space, a fluid-conducting conveying means arranged between the first internal space and the second internal space, whereby the first container and the second container are axially connected to each other.

An improved applicator and a method for applying two or more components which can be mixed together. They are intended to effectively prevent unintentional and unintentional mixing of the components at the discharge orifices and any associated uncontrolled or undesirable reaction of the components with each other during downtime of the applicator. The applicator/application device (1) for the application of at least two components can be mixed with one another, comprising coaxially arranged one within the other component feeds (2, 3) with the component feeds (2a, 3a) for the respective at least two components and component discharge orifices (2b, 3b) associated with the component feeds (2, 3),

The invention relates to a method for producing a bone cement with a device comprising a cartridge (1) having a cylindrical interior (2), cement powder (6), and monomer liquid (7) in a monomer liquid container (8), a cartridge head (3) having a discharge opening (9), a closure (10) in the discharge opening (9), which closure is permeable to gases and impermeable to powder particles, a drive piston (5), and a central piston (4), wherein the central piston (4) is permeable to gases and the monomer liquid (7) and impermeable to the powder particles of the cement powder (6) and is arranged between the drive piston (5) and the cartridge head (3), wherein the central piston (4) separates the interior (2) into a first cavity (12) and a second cavity (14), the method comprising the following steps:

A) moving the drive piston (5) toward the cartridge head (3),
B) opening the monomer liquid container (8) via the movement of the drive piston (5) and releasing the monomer liquid (7) in the second cavity (14),
C) expelling residual gases into the surroundings of the device by means of the movement of the drive piston (5),
D) injecting the monomer liquid (7) through the central piston (4) into the cement powder (6),
E) displacing gases between the powder particles with the inflowing monomer liquid (7),
F) wetting the powder particles of the cement powder (6), and
G) depressurizing the second cavity (14), wherein the depressurization takes place by partially removing the contained monomer liquid (7).

The invention also relates to such a device for mixing a bone cement, with a depressurization device (16).

One aspect relates to a method of producing a bone cement from at least two starting components in a device comprising a first hollow cylinder-shaped container and a second hollow cylinder-shaped container, a vessel arranged in the first container, whereby a monomer liquid is stored in the vessel. The aspect also relates to a device for providing a bone cement from two starting components, comprising a hollow cylinder-shaped first container, in which a vessel for a monomer liquid as first starting component can be stored, a hollow cylinder-shaped second container comprising a first internal space, in which a bone cement powder as second starting component can be stored, and a second internal space into which the monomer liquid can be conveyed, a fluid-conducting conveying means arranged between the first internal space and the second internal space, whereby the first container and the second container are axially connected to each other.

The beverage apparatus can include one or more sensors, devices, or assemblies that can be used to detect a volume of liquid in the chamber or a liquid level in the chamber. The beverage apparatus can include an apparatus processing portion (ACP) and an apparatus database portion. The beverage apparatus of the disclosure can include various additional features.

A cosmetic container with a discharge structure for mixing heterogeneous contents according to one embodiment of one aspect of the present disclosure includes: a container body in which heterogeneous contents are stored; a discharging device for discharging the heterogeneous contents stored in the container body; and a button configured to operate the discharging device and formed with a discharge passage and a discharge port, wherein a mixing shaft member and a mixing cap member are formed in the discharge passage and the discharge port, so that the heterogeneous contents are mixed with each other.

One aspect relates to a device for mixing a polymethyl methacrylate bone cement formed of two starting components and for storing the starting components of the bone cement. The device has a tubular cartridge with a cylindrical interior. A powder is contained in a front of the cartridge and a container containing a monomer liquid is arranged in a rear of the cartridge. A discharge piston is arranged between the container and the powder, and a conveying piston is on the side of the container opposite the discharge piston. The discharge piston and the conveying piston are arranged in the interior of the cartridge movably in the longitudinal direction. A conduit is provided that connects the front part and the rear part of the interior of the cartridge to one another in a manner permeable for the monomer liquid and for gases and which is impermeable for the powder.
