A cosmetic container assembly capable of simultaneously discharging multiple kinds of contents through a single pumping action is disclosed. The cosmetic container assembly includes a plurality of cosmetic containers, each of which includes a container and a pump dispenser capable of pumping and extruding the contents in the container through a piston rods, a base including a button-supporting shaft, a press plate, through which the button-supporting shaft extends, the press plate including connection ports fitted over the piston rods, a discharge port, discharge channels connecting the connection ports with the discharge port, and a support shaft, and a lever push button, which presses the support shaft and the press plate and thus simultaneously presses the pump dispensers to perform a pumping action when the lever push button is pressed.

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

The present invention relates to a system of converting dispensing packs with two or more compartments with a fixed volume to modified ratio dispensing packs or dispensing packs with one compartment to multiple compartment dispensing packs using modified compressible foam or fibre inserts.

An apparatus for applying a two-component liquid composition to a surface has a housing having an open end, an inner surface and an outer surface, an applicator retained in the housing and projecting through the open end, two containers removably mounted to the inner surface of the housing, each container having a dispensing nozzle extending through an aperture in the housing and arranged adjacent the applicator. There is a cutting device arranged on the housing adjacent the nozzles, the cutting device having at least one blade, wherein pressing the cutting device causes the blades to pierce the nozzles and allow contents of the containers to exit the containers and flow to the applicator.

Methods, apparatus, devices and systems for mixing and dispensing multi-component materials. The mixing and dispensing may be performed using a mobile, enclosed dispenser that can be used to supply a mixed multi-component material at the point of use. In some embodiments, the components to be mixed into the multi-component material may be supplied in cartridges.

A storage and mixing system, for pasty two-component polymethyl methacrylate bone cements, comprises a cartridge with a cylindrical interior, a cartridge head that closes an end of said cartridge, a partition wall axially disposed in the cylindrical interior of the cartridge, wherein said partition wall is connected to the circumferential surface of the cylindrical interior of the cartridge and divides the cylindrical interior of the cartridge delimited by the cartridge head into two spatially separate cavities. The first cavity includes a first pasty cement component and the separate second cavity includes a second pasty cement component, two delivery plungers close the two cavities on the side of the cavities opposite the cartridge head. At least two cutting edges are disposed on the front side of the sleeve-shaped connecting means facing the cartridge head, such that the at least two cutting edges cut off the partition wall from the cylindrical inner wall of the cartridge as at least one cut-off strip when the delivery plungers are advanced towards the cartridge head in the cavities with the connecting means, and wherein the sleeve-shaped connecting means comprises a deflecting surface which is inclined to the axis of the connecting means which, on advancing the connecting means, presses the at least one cut-off strip of the partition wall towards the inner wall of the cartridge.

Various embodiments of the present disclosure provide a cartridge for dispensing two-part fluids. In one embodiment, the cartridge comprises a cartridge body having a dispensing end and defining a first fluid reservoir and a second fluid reservoir. The dispensing end defines at least one aperture fluidly connected to the first fluid reservoir. The dispensing end also defines a dispensing conduit fluidly connected to the second fluid reservoir. The cartridge further comprises a nozzle member engageable with the cartridge body to form an outlet and to fluidly connect the at least one aperture to the outlet.

A multi-color press-type cosmetic pen includes a cylindrical pen body, a pen tip, and at least two actuating mechanisms. Each actuating mechanism includes a button, a ratchet, a ratchet wheel, a screw rod, a nut, a piston, and a spring. The button is fixed to the ratchet. Each of the ratchet and the ratchet wheel is hollow and cylindrical. The ratchet wheel is inserted into the ratchet. At least one inclined surface is provided on the outer peripheral wall of the ratchet wheel, and an abutting portion matched with the inclined surface is provided on the inner peripheral wall of the ratchet. The screw rod is inserted in the ratchet wheel. The nut is fixed on the pen body. The piston is mounted on the head the upper end of the screw rod. The spring abuts between the nut and the ratchet wheel.

A dispenser assembly having a plunger and a housing is provided. The plunger has an inner plunger portion and an outer plunger portion disposed concentrically around the inner plunger portion. The housing has an inner tubular housing wall, an outer tubular housing wall, and first and second outlet members. The outer tubular housing wall is disposed concentrically around the inner tubular housing wall. The inner tubular housing wall defines a first interior region therein, and the inner tubular housing wall and the outer tubular housing wall define a second interior region therebetween. The first and second outlet members fluidly communicate with the first and second interior regions, respectively. The inner plunger portion is slidably received in the first interior region. The outer plunger portion is slidably received in the second interior region.
