A dispenser for applying liquid, having a housing with an applicator opening and a liquid reservoir. The dispenser has a ventilation duct by which an ambient atmosphere is connected to the liquid reservoir so that, after the application of liquid, an inflow of air from the atmosphere is permitted into the liquid reservoir. The dispenser is provided with a detection installation which for detecting an application procedure detects air flowing in through the ventilation duct. The dispenser has a protective cap covering the applicator opening on the housing. The dispenser in the ventilation duct has a switch valve operable by activating a push-button on the external side of the housing. The protective cap acts on the push-button when placed on the housing or when the protective cap is being placed thereon to open the switch valve.

There is provided a cosmetic vessel. The cosmetic vessel includes an airless pump configured to discharge cosmetics accommodated therein by using a piston that rises in a cylinder, a discharge plate provided at one side of the airless pump and having at least one discharge hole, and a guide unit provided between the airless pump and the discharge plate. A lower end of the guide unit is combined with the piston and rises or falls in a state of being integrated with the piston.

A chemical resistant elastomeric cap that can be secured to the head of a pump type liquid dispenser with a delivery nozzle that can be used to seal off the dispenser nozzle to prevent fluid dripping from the end of the nozzle and to prevent air from reaching the end of the nozzle to dry fluid in the nozzle outlet orifice and/or the nozzle tip. The cap is one piece and has an attachment ring of elastomeric material than can to fitted around the dispenser head to retain the cap with the dispenser and the attach bottle whether the cap is fitted over the nozzle or free from the nozzle.

The invention relates to a closure device comprising a closure wall having a communication conduit passing through it and intended to close the opening of a container of a product and a stopper movable in the duct. The stopper comprises a cavity open on one side of the wall, closed by a bottom and comprising at least one lateral opening. In the closed position, this bottom closes the conduit, and in the open position, the side opening(s) and said bottom exit the conduit, the conduit thus being open in fluid communication through the stopper. The invention also relates to a product refill comprising a container closed by this closure device. It also relates to a dispensing device comprising this refill and a dispensing head.

A valve for a dispenser pump is carried on a circular post or tube of a pump body. A protruding, sealing flange is formed at one end, while the opposing end includes tapering ribs extend along the inner surface of the hollow, tubular valve. In function, the ribs facilitate the passage of make-up air between the inner surface and the post/tube.

A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

A micro pump vessel has an outer vessel on one side of which a button is formed and an outer vessel lid which is hinge-coupled to one side of the outer vessel to be opened and closed. In the vessel, a first and a second pistons are installed on an upper surface of cosmetic contents, and thus, when the cosmetic contents are pumped and used by the operation of a micro pump, the first and the second pistons lower to exhaust all the cosmetic contents so as not to discard the remaining cosmetic contents.

The invention relates to a device for dosing liquid from a liquid-receiving element (2), in which the liquid-receiving element (2) comprises an outlet valve (1), and a dosing system is available, said dosing system consisting of a first actuating wing (4) and a second actuating wing (5), which are arranged around the liquid-receiving element (2) and can be moved in relation to each other such that they compress the liquid-receiving element (2), a mechanical dosing stop being available.

A bag-in-bottle type of a squeeze dispenser comprising a housing, a cap, a flexible bag for containing fluid, and means to equilibrate atmospheric air pressure with air pressure inside the housing is disclosed. Said means include a closable air channel. The closable air channel, and the cap, may each be in an open or a closed position. When the cap is in an open position, the closable air channel is in a closed position, thus substantially locking the air inside the housing in place and allowing for fluid to be dispensed from the flexible bag upon application of pressing force on the sidewalls of the housing. When the cap is in a closed position, the closable air channel is in an open position, allowing for a flow of atmospheric air into, and out of, the dispenser housing and thereby equilibrating the air pressure inside the housing with air pressure of the atmospheric air.

The invention relates to a product packaging and dispensing device (10) which comprises a container (12) containing the product to be dispensed; a sub-assembly attached to the container (12) and comprising a grooved neck (14), a pump (16) and a push member (18) actuating the pump (16) by manual pressure; and a closure cap (20) having a first ribbed cylindrical wall (200) engaging on the grooved neck (14), thus forming a bayonet-type connection system. The sub-assembly has an annular surface (140) provided with at least one lug (142). The cover (20) has a second wall (300) provided with at least one axial rib (304) abutting against the at least one lug (142) when the cover (20) is in a closed position, The second wall (300) has two diametrically opposed regions (306) that can be deformed by manual pressure so as to allow rotation of the cover (20) by releasing the at least one rib (304) from the at least one lug (142).
