Spray dispenser for nasal drugs includes a non-pressurized bottle for storing medical fluids in particular of drugs and other sterile fluids, a mounting body mounted to the top of the bottle and an actuating body, wherein the bottle, the mounting body and the actuating body are aligned along a longitudinal axis, and wherein the actuating body is slideably attached to the mounting body along the longitudinal axis and movable between an actuating position and a non-actuating position, wherein the spray dispenser includes an applicator nozzle and an actuating section for moving the actuating body into the actuating position, characterized in that the applicator nozzle has a nozzle axis which is inclined with respect to the longitudinal axis, the applicator nozzle facing away from the actuating section.

The present invention relates to an airless cosmetic container comprising: a lower container (10) having an opened lower part; an inner container (20) which is a cylindrical member inserted through the upper opening of the lower container (10) and having a closed lower part, and which has an upper outer flange (21) mounted on and assembled to the upper end of the lower container (10); a container cover (30) which is a cylindrical member for covering the upper opening of the inner container (20), and of which a lower protruding groove (31) protruding downwards from the center thereof is positioned in a cylinder (22) protruding from the center of the inner container (20) and an outer end (32) is coupled to two vertical protruding rods (23) protruding toward the upper part of the upper outer flange (21) of the inner container (20); a cylindrical spring (40) coupled in the container cover (30); a disc-shaped upper lid (50), having a recessed upper surface, coupled to the upper part of the cylindrical spring (40); a disc-shaped lower lid (60), which is a member coupled to the lower surface of the center of the upper lid (50), has a discharge hole (61) formed in the center thereof, and has a fastening cylinder (62) formed at the lower part of the discharge hole (61); a pump body (70) coupled to the fastening cylinder (62) of the lower lid (60) and inserted into the lower protruding groove (31) of the container cover (30); an exhaustion piston (80) coming in close contact with the inner periphery of the inner container (20) and the outer periphery of the cylinder (22) protruding in the center thereof, so as to rise as cosmetic contents are used; and an upper case (100) which is a cylindrical member for covering the upper side of the lower container (10), and of which one side is hinge-coupled to one side wall of the lower container (10) and the other side is hooked and coupled to an opening/closing button (90). The present invention has effects of: preventing external air from flowing into an upper cylinder since the inner diameter of the discharge hole is formed to be smaller than the inner diameter of the fastening cylinder of the lower lid such that, when a piston support and the lower lid are coupled, the upper end surface of a center hole of the piston support comes in close contact with, that is, overlaps with the lower surface of the discharge hole in the fastening cylinder of the lower lid, so as to reinforce faste

A dispensing container capable of changing the ratio between the amounts of two kinds of contents to be dispensed, includes two container bodies, two pumps including two stems, an adjusting member configured to press the stems and to be rotatable about an axis extending in a substantially vertical direction, and a pressing head configured to, in response to a depressing operation, rotate about an axis extending in a substantially horizontal direction, to thereby depress the stems via the adjusting member. The adjusting member includes a plurality of pressing portions against which the stems are pressed, and when the adjusting member is rotated about the axis, a depressing stroke of the one of the plurality of pressing portions on the side of one of the stems becomes shorter, and a depressing stroke of the other one of the plurality of pressing portions on the side of the other stem becomes longer.

Pump dispenser comprising a pump and a container for liquid to be dispensed, the pump comprising a pump body mounted in the neck of the container and a plunger reciprocable relative to the pump body to alter the volume of a pump chamber defined in the pump body and having an inlet and an outlet, the outlet leading through an outlet passage to a discharge opening. The pump cylinder body is retained at the container neck. A vent is provided in the cylinder body wall adjacent the neck edge. A vent block ring is disposed in the cylinder body adjacent the vent, and is moveable between blocked and unblocked positions relative to the vent. The vent block ring has an integral upward projecting formation which is engaged by part of the plunger in a locked-down position of the plunger, so that when the plunger is locked down the vent block element blocks the vent, while in a relatively extended position of the plunger the vent block element is in the unblocked position.

A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.

Automatic electric actuation of the pump of a liquid dispenser apparatus is provided by a stepper motor having a threaded hollow liquid-conducting tube positioned therein and configured such that motor drives the hollow tube up and down in response to supply of a plurality of electrical pulses thereto. A lower end of the hollow tube is constructed to inter-fit with a stem of the pump such that driving the hollow tube up and down creates a pumping action.

A multi-composition product dispenser capable of concurrently dispensing at least a first and second composition is provided.
