The present invention relates to a spuit-type cosmetic container, and more particularly to a spuit-type cosmetic container capable of extracting an exact amount of cosmetic contents and improving convenience in use as a retractable button and a piston are moved down and fixed when a cap part is coupled to a container body by rotating the cap part, and then the retractable button and the piston are moved up so that the cosmetic contents are sucked into a spuit tube and used when the cap part is separated from the container body by rotating the cap part. The spuit-type cosmetic container according to the present invention includes a container body (110) provided at an upper portion thereof with an opening, an inner cap (132) screwed with the opening (112) of the container body (110), formed in an outer circumference thereof with a rotation annular groove (132d), and including an outer sidewall (132e) formed therein with a slit (132f), and a cylinder (132a) formed in the outer sidewall (132e), an outer cap (134) coupled to an outer portion of the inner cap (132) and provided on an inner circumference thereof with a cam protrusion (134a) and a rotation protruding wheel (134b), a retractable button (140) coupled to an inner upper portion of the outer cap (134) movably up and down within a predetermined stroke distance, and including a cam hole (142) having an oblique guide part (142a) and a stop hole (142b) formed in an outer sidewall (141), an anti-rotation step (145a) vertically formed on an inner sidewall (145), and a piston fixing rod (144) formed at a center of the retractable button (140), a piston (150) fixedly fitted to the piston fixing rod (144) of the retractable button (140) to move up and down together with the retractable button (140), an elastic member (160) fitted to the outer sidewall (132e) of the inner cap (132) to elastically support the retractable button (140), an anti-separation member (180) coupled to an inner portion of a lower end of the outer cap (134) to prevent the outer cap (134) from being separated from the inner cap (132), and a spuit tube (120) coupled to a spuit tube coupling rod 132c of the inner cap (132) to suck up a cosmetic content contained in the container body 110 (spuiting).

A plunger is fittable within a cylinder of a pneumatic dispenser that discharges a viscous material. The plunger has a first portion located at the front, and a second portion located at the rear. The second portion is a hollow structure and has a circumferential wall. An inner circumferential surface of this circumferential wall has a tapered surface. The circumferential wall has a thickness dimension that decreases in the axial direction moving away from the first portion. Therefore, the circumferential wall easily displaces in the radial direction, because the bending stiffness decreases in the axial direction moving away from the first portion. The first portion is a solid structure that is more rigid than the second portion. The first portion also has a partition wall surface that separates the inner chamber of the second portion from the solid section of the first portion.

A fluid containment and dispensing system includes a sealed, variable-volume containment device having a movable plunger slidably mounted within a barrel, and a sealing head having a seal insert retained thereon. A seal arrangement includes a self-resealing cross-slit opening, an internal sealing ring for engaging a corresponding coupling of a compatible device, and a raised peripheral seal ring for sealing engagement with a closure lid.

A multistage syringe includes a first barrel, a second barrel, a second barrel seal assembly, and a plunger assembly. The first barrel includes a first barrel channel and the second barrel includes a second barrel channel. The first barrel couples to the second barrel such that the first barrel channel aligns with the second barrel channel along a central axis. The plunger assembly includes a plunger coupled to a plunger handle. The plunger slidably couples with the first barrel channel along the central axis and the second barrel seal assembly slidably couples with the second barrel channel along the central axis. The plunger and the second barrel seal assembly cooperate to maintain a seal as the plunger transitions between a distal end of the multistage syringe and a proximal end of the multistage syringe.

A fuel changing device which is for connection with a fuel pipe or a fuel can is provided, including: a barrel, connected with a conduit portion communicating with an interior of the barrel; a plunger, including a piston movably received in the barrel and an operation rod connected with the piston and extending out of the barrel; an adapting mechanism, including an adapter connected to the conduit portion and at least one adapting tube, the adapter selectively detachably connected with one end of the adapting tube or for selectively detachably connected with a fuel connector of the fuel can, another end of the adapting tube being for detachably connected with the fuel pipe.

A bag-in-bag-in-bottle assembly formed by a flexible dispensing container with a dispensing fitment. The dispensing container is positioned adjacent or sandwiched between one or more flexible pressurization containers having a separate inlet/outlet path through a second fitment. The bag-in-bag assembly can then be placed in a containment vessel with the fitments mounted such that it is accessible on the vessel. A liquid can be extracted from the dispensing container by introducing a fluid into the pressurization container(s) with enough pressure to force the liquid out through the dispensing fitment. A contoured dispensing head may be coupled to the bag-in-bag-in-bottle assembly using a cam actuation arrangement for simultaneously locking the pressurization, vent and fluid extraction couplings.

A pressure control fill valve for a pressurized dispenser container comprises a first and second end and a base, a first and second circumferential lip. The lips enable placement of the valve in an opening of a pressurized dispenser container in first a position, where a propellant gas can be filled into the container and a second position for complete closing of the container. According to the invention, the second lip of the valve is asymmetric about its circumference. This prevents the valve from being pushed out of the opening of the container in case of high over-pressure or enlargement of the opening due to a temperature increase. The invention eliminates the hazard of a loss of valve and propellant gas in case of high temperature.

Exemplary embodiments of dispensers are disclosed herein. One exemplary dispenser is a soap or sanitizer dispenser. The dispenser includes a housing. A removable and replaceable concentrate container for holding concentrated soap or sanitizer is located within the housing. A concentrate pump is in fluid communication with the concentrate container. A diluent container for holding a liquid is also located within the housing and a diluent pump for pumping the diluent is also included. The dispenser includes a mixing chamber in fluid communication with the concentrate pump and the diluent pump. The dispenser includes an outlet. When concentrated soap or sanitizer is pumped from the concentrate container, it mixes with diluent pumped from the diluent container to form a diluted mixture. The diluted mixture is dispensed at the outlet of the dispenser.
