A piston for a reservoir of a dispenser of a fluid product without air intake, and presenting a central axis X includes both sealing means and also guiding means. The sealing means extend in a plane orthogonal to the axis X and define a single external sealing line in a closed loop, distal from the axis X, capable of coming into contact with an inner wall of the reservoir 10. The guiding means include a base from which extends one or more tabs with free ends defining external guide points, distal from the axis X, capable of coming into contact with the inner wall of the reservoir.

Proposed herein is a dispenser type beverage container including: a cartridge cover member having a cartridge insertion space into which a cartridge storing a target material to be mixed is inserted; a main body located below the cartridge cover member to contain the target material discharged from the cartridge in an inner space thereof; and a button member of which the inner face of the upper portion capable of doing a rectilinear motion is arranged to meet an end of the cartridge inserted into the cartridge cover member, so that the target material stored in the cartridge is discharged into the main body when the upper portion is pressed down by external pressure.

A feed out container includes: a metal main body outer sleeve formed as a bottomed cylinder; a metal cylindrical inner member having a first portion provided within the interior of the main body outer sleeve and a second portion that constitutes an annular protrusion; an inner plate that holds a contained material; a lid body outer sleeve formed as a bottomed cylinder; a lid body inner sleeve provided within and in close contact with the interior of the lid body outer sleeve; and a feed out mechanism that moves the inner plate in an axial direction of the sleeve to feed out the contained material. At least one of a first O ring (31) that maintains an airtight seal between the lid body outer sleeve and the inner member and a second O ring fitted about the periphery of a portion of the inner member is provided.

A container 10 for mixing and dispensing of material having a liquid receptacle 14 and a plunger 18. The receptacle 14 has a front portion 36 and the plunger 18 has a forwardly projecting sharp protrusion 42 having a shaft 72 which terminates in a sharp outer end 78, 82. Upon the plunger 18 being depressed the sharp protrusion 42 pierces a front portion 36 of the liquid receptacle 14 and the liquid in the receptacle 14 is pushed hydraulically through the front portion 36 into the main chamber 17. Thus the liquid contacts material in the main chamber 17 to form a mixture. The plunger 18 can continue to be depressed so as to break the front portion 36 of the liquid receptacle 14 away and then push the material in the main chamber 17 towards a dispensing nozzle 26. The main chamber 17 has a frangible membrane 22 at a distal end 13 thereof which is hydraulically broken by pressure applied from the material in the main chamber 17 so that the material can be dispensed from the container 10. The container 10 is particularly envisaged for use with mixing and dispensing of dental materials.

Tampon dispensing devices and methods for using the same are provided. In some embodiments, a tampon dispensing device includes a display that presents one or more codes for receiving a tampon, an actuator that is connected to a spindle structure that dispenses the tampon from a plurality of tampons stored in a storage unit, and a controller that is connected to the display and the actuator, where the controller is configured to: receive, from a server, a code for dispensing one of the plurality of tampons; present the received code on the display; receive, from the server, a request to dispense one of the plurality of tampons from the storage unit; and transmit an instruction to the actuator that causes the actuator to rotate a spindle structure such that the tampon is dispensed from the storage unit into a dispensing area.

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.

An environmentally friendly push-pull type non-circular cylindrical container includes a paper lid. A bottom side of the paper lid is fixedly installed with an inner tube that is fixedly sheathed with an elliptical tube. An inner wall of the elliptical tube is fixedly installed with a bottom bracket and a fixed gasket. A same rotary toothed piece is movably installed on a side of the bottom bracket and the fixed gasket close to each other. An inner wall of the toothed piece is movably installed with a limiting wood shaft. A threaded rod is movably installed on the limiting wood shaft, and is movably sheathed with a gasket located on a top side of the toothed piece. The threaded rod is sheathed with a nut, a piston piece is fixedly installed on a top side of the nut, and the piston piece contacts an inner wall of the inner tube.

The invention relates to an applicator device comprising an applicator tip and a container part, wherein the container part comprises: (i) a container comprising a container wall, a valve, and a plunger, wherein the container wall, the valve, and the plunger together define a storage volume for containing a liquid, wherein the plunger comprises a circumferential wall, sealingly contacting the container wall; and (ii) a plunger advance system functionally coupled to the plunger and configured to advance the plunger for reducing the storage volume for expelling at least part of the liquid via said valve to said tip, wherein the plunger advance system is arranged outside the storage volume; wherein (a) the valve comprises a first spring system comprising a first spring material comprising a stainless steel material comprising a molybdenum content selected in the range of 0.5-7 wt. %, and (b) the plunger advance system comprises a second spring system comprising a second spring material comprising a stainless steel material comprising a molybdenum content selected in the range of 0.5-7 wt. %, applies; and the plunger advance system comprises a polymer selected from the group consisting of polypropylene (PP), ethylene chlorotrifluoroethylene (ECTFE), and polyoxymethylene (POM); and wherein the plunger advance system comprises a spindle system comprising a ratchet system comprising a first element and a second element, wherein the second spring system is configured to provide the first element and the second element to engage on each other.
