A liquid dosing device for dispensing a metered dose of liquid from a squeezable container, comprising an outlet passage leading to a discharge opening; a dosing chamber positioned behind said discharge opening and having at least one entrance opening allowing a charging flow of liquid from said container into said dosing chamber under the influence of weight of liquid, and a drive opening allowing a control flow of liquid from said container into said dosing chamber in response on a rise of pressure of liquid in the squeezable container; a floating plunger movably arranged in the dosing chamber so as to advance upon said rise of pressure from a rest position in which under the influence of a lifting force of buoyancy said floating plunger closes said drive opening, into a blocking position in which said floating plunger blocks said outlet passage, wherein said floating plunger when advancing into said blocking position, pushes said liquid charged into said dosing chamber, to said outlet passage; a stop seat upon which said floating plunger acts in its blocking position, and a sealing lip for closing said outlet passage, being arranged such that a seat-sided portion of the floating plunger or a plunger-sided portion of the stop seat and said sealing lip is formed, particularly injection-mold, of one single piece of the same plastic material.

Provided is a cream-type cosmetic container having a vacuum pump which is configured such that a pumping member performs a pumping operation to discharge contents when a handle part is rotated by a predetermined section. Thus, contents having high viscosity can be discharged even with a small force. Furthermore, the container is configured such that a discharged amount of contents is adjusted according to a rotation angle of the handle part. Therefore, a user can use the container while adjusting discharged amount to a desired amount.

A device has a first part with a valve seat and storage chamber, and a second part with a flexible valve cover and actuator. The storage chamber may be formed from a pre-form blow-molded into a flexible pouch defining a variable-volume storage chamber. The flexible valve cover and valve seat form a normally closed valve seam therebetween. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one-way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam, and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam. The one-way valve may have anti-spritz features for using the device to dispense a substance, such as to the eye. The device may contain prostaglandins without the device material absorbing the prostaglandins material and/or without the material being adsorbed into the drug.

A measurable dispenser, comprising a first vessel for containing a substance to be dispensed, a second, measurable, vessel, mounted on the first vessel, a one-way valve whereby fluid from the first vessel can be caused to move into the second vessel and retained therein virtue of the one-way valve, and wherein the second vessel is provided with one or more indicia indicating measured amounts. A child-proof locking mechanism is also disclosed.

A sealing vent for a foaming dispenser associated with a squeeze foaming container is described. The vent has an annular structure, with a central aperture encased by a multi-tiered disc section connected to inner facing of a thickened, axial wall. An upward angled, outer flange is connected on an outer facing of the axial wall, and the outer flange is attached at a lower elevation along the axial wall in comparison to the disc section.

A metering dispenser for simultaneously or selectively discharging two media, including an outlet opening, a first reservoir for a first medium, a first metering-conveyor device for conveying the first medium from the first reservoir, a second reservoir for a second medium, a second metering-conveyor device for conveying the second medium from the second reservoir, a mixing chamber arranged upstream of the outlet opening and in which the first medium, conveyed by the first metering-conveyor device, and/or second medium, conveyed by the second metering-conveyor device, is stored temporarily, and an output-conveyor device for conveying the medium or media from the mixing chamber to the outlet opening. The first metering-conveyor device has the form of a metering-pump device with a variable-volume metering chamber, an inlet fluidically connected to the first reservoir and having an inlet valve, and an outlet fluidically connected to the mixing chamber and having an outlet valve.

A dispensing head for a system for dispensing a product, having a body having a well for mounting the head on a tube for the pressurized supply of the product and a recess in communication with the well by means of a dispensing path. The recess being equipped with a nozzle delimiting a dispensing space between the path and a discharge passage formed in the nozzle. The nozzle being equipped with an insert that has a membrane forming, in the space, a communication interface between an upstream part in which the path emerges and a downstream part that supplies the discharge passage. The membrane being reversibly deformable by the product exerting pressure coming from the upstream part, between a resting state in which the size of the interface is minimal and a stressed state in which the size of said interface is increased in order to provide dispensing.

A spray device includes side-by-side spray tips that are spaced from one another at a distal end of the spray device. A first spray tip has a first fluid pathway defining a first flow area. The first fluid pathway has a first swirl chamber having an outer perimeter and flutes having inner ends that direct a first fluid into the outer perimeter of the first swirl chamber for rotating the first fluid in a circular pattern. A second spray tip has a second fluid pathway that defines a second flow area that is larger than the first flow area. The second fluid pathway has a second swirl chamber having an outer perimeter and flutes having inner ends that direct a second fluid into the outer perimeter of the second swirl chamber for rotating the second fluid in a circular pattern.

A fluid dispenser device including an outlet, a pocket having an interior volume for containing a fluid, the interior volume being delimited at least in part by a movable wall, a reservoir arranged to contain the fluid, a pocket cap, a cavity, a reservoir orifice joining the reservoir and the cavity; wherein the pocket cap is arranged to be mounted by insertion in the cavity of the device so as to be mounted by extending: —by passing through the pocket at least partially while passing through the movable wall or—by going along the pocket at least partially, the device comprising an inlet orifice arranged to insert the pocket cap into the device from the outside of the device and opening into the cavity.

The device (100) for packaging and dispensing a product, liquid or in gel form, optionally for an ophthalmic application, comprises a container (1) containing the product to be dispensed by a dispensing head (7), as well as a refilling and filtering assembly for the air entering the container (1) after a dispensing, the dispensing head delimiting one or more dosing chambers (5) and including at its end a flexible part (7) which can be actuated to allow the release of the dose of product in a compressed state of said chamber (5). The air refilling and filtering assembly has a sterilizing filter (11) which cooperates with a check valve (12), this assembly (11, 12) being typically located in a central or inner portion of the head (7). The supply of outside air is accomplished by means of a channel (16) leading to an outer orifice (10) able to be obturated by a cover (15).
