A valved container assembly which has a container for containing a fluid, the container extending in an axial direction and having an open front end and a valve disposed in the container. The valved container assembly is configured so that forward axial movement of the valve relative to the container is inhibited. A plunger element is disposed axially rearward of the valve and is axially moveable in the container. The plunger element is configured to increase the pressure of a fluid in a first volume of the container upon forward axial movement relative to the valve. The valve includes a channel bypassing the permanent seal, the channel having a first opening in fluid communication with the atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal.

The present invention relates to a multistage gear-driven container for ejecting a paste material, which can control the ejection of paste by means of the operation of multistage drive gears so as to enable a stable ejection control, controls the ejection of the paste by means of the operation of the multistage drive gears, thereby exhibiting an effect of being able to perform more stable driving than the conventional lift screw, and forms an assembly-type structure having a removable container body, thereby providing an advantage of replacing only the container body storing paste products and enabling a lower driver to be reused.

The present invention is directed to a spray applicator for spraying a tissue treatment medicant onto a tissue that has a container containing the medicant and is positioned at a proximal end of the spray applicator; a spray tip positioned at a distal end of the spray applicator; a cannula connecting the container with the spray tip; an actuatable dispensing mechanism at a proximal end of the applicator to express the medicant from the container through the cannula and through the spray tip toward the tissue; an optional pressurized gas source discharging a gas through the cannula in the vicinity of the spray tip or inside the spray tip; and a distance indicator that provides indicia of the distance between the spray tip and the tissue but does not prevent positioning the spray tip closer to the tissue than a defined distance for the distance indicator.

An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.

A liquid dispenser for cosmetic liquids having a liquid reservoir and an applicator. An outlet channel connects the reservoir to the applicator, the outlet channel being formed either valveless or with an outlet valve. The liquid dispenser has a pressure generating device which pressurizes liquid in the reservoir for conveyance through the outlet channel to the applicator. The pressure generating device has an air pumping device which feeds and an actuating pressure chamber. The actuating pressure chamber adjoins, and is separated from, the reservoir by a displaceable wall so that an overpressure in the actuating pressure chamber leads to an overpressure in the reservoir. The air pumping device has manual actuator, allowing air to be pumped into the actuating pressure chamber by the actuator, so that the overpressure in the actuating pressure chamber and in the reservoir rises sufficiently to convey liquid from the reservoir to the applicator.

A nasal fluid dispenser device comprising: a body (10) comprising a hollow sleeve (11) and a top surface (15); and an actuator member (40) that is mounted to slide in said body (10) so as to actuate the device; the device further comprising two nasal extensions (20, 30), at least one of which forms a dispenser head provided with a respective dispenser orifice (21, 31), said nasal extensions extending from said top surface (15), each dispenser head being connected, during actuation, to a respective reservoir (50) that is arranged in said body (10), said two nasal extensions (20, 30) forming an angle lying in the range 30° to 60° relative to a longitudinal central axis (A) of said body (10).

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.
