An all-plastic emulsion pump, includes a body, threads, pressing head, main column, suction tube, plastic spring, pull rod, stopper, lock cover, first and second one-way valve devices made of plastic material. A communication port is between the plastic spring and the main column. The pull rod is in the plastic spring. The stopper is connected to the pull rod upper end. When the plastic spring is pressed, there is a gap between the pull rod and the side wall of the communication port. When the plastic spring pops up, the stopper blocks the communication port. The first one-way valve device is between the pressing head and the main column to supply the emulsion to the pressing head. The second one-way valve device is between the plastic spring and the inlet of the body to supply the emulsion from the inlet of the body into the plastic spring.

A liquid dispenser, having a large ring, a connecting cover, and a hollow pump frame, the pump frame is movably clamped to the interior of the large ring, the top of the pump frame extends to the outer side of the top of the large circle, a bottom protruding portion of the connecting cover extends into a top groove of the pump frame so as to be movably clamped thereto, a first air outlet is provided on both sides of the bottom of the connecting cover, and a second air outlet in communication with the first air outlet is provided to penetrate through the pump frame. The first air outlet, the second air outlet, the first liquid outlet, and the second liquid outlet can be opened and closed by rotating the connecting cover to change a position relationship between the connecting cover and the pump frame.

In the discharger, a stopper is swingable between a restriction position which comes into contact with or approaches a locking target portion to restrict downward movement of a discharge head and a restriction release position where the restriction and locking target portions are separated to allow downward movement of the discharge head by the stopper being swung rearward from the restriction position, the stopper including the restriction portion, a finger hook outward from a depressing member in a left-right direction, and a contact target portion that comes into contact with the depressing member when the stopper is at the restriction position or when the depressing member rotates downward around a rotation axis where the stopper is at the restriction position, and a restraint protrusion protruding downward is formed at a portion of the depressing member rearward of a contact portion with which the contact target portion comes into contact.

An dispenser includes a housing, a container disposed in the housing for holding a liquid, a nozzle, and a pump. The pump is disposed between the container and the nozzle. The pump includes a pump inlet, a pump outlet, a pump chamber, a first check valve, and a second check valve. The pump inlet is in fluid communication with the container and the pump chamber, and the pump outlet is in fluid communication with the pump chamber and the nozzle. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the container and the pump, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the pump, and the second check valve has a second cracking pressure. The first cracking pressure of the first check valve is greater than the second cracking pressure of the second check valve.

A fluid dispenser having a first fluid outlet for dispensing fluid when in a first orientation and a second fluid outlet for dispensing fluid when in a second orientation. An outlet valve mechanism directs the fluid towards the first fluid outlet in the first orientation, and towards the second fluid outlet when in the second orientation. The outlet valve mechanism includes a movable outlet member that is located at a first position when the fluid dispenser is in the first orientation, and is located at a second position when the fluid dispenser is in the second orientation.

A pressurized spray A is provided with a cap part 1, a body part 3 capable of being attached to the cap part, a base body 2 that is attached to the body part 3, an introduction pipe 4 for introducing a liquid in a container attached to the base body 2, a nozzle part 5 attached to the body part 3, a cylinder part 6 attached to the body part 3, an F valve 7 attached to the bottom of the cylinder part 6, a piston part 8 that is allowed to slide inside the cylinder part 6, a pivotal trigger 9 that moves the piston part 8 in forward and backward directions, a restoring spring part 13 for restoring the trigger 9, a pressurized valve (S valve 10) attached to a passage of the body part 3, and a pressing spring part 11 for pressing the pressurized valve in a valve closing direction, and by pivotally moving the trigger 9, the pressurized spray A jets out the liquid, and a liquid passage 12 that communicates with the inside of the cylinder part 6 is formed between the base body 2 and the body part 3 so that the liquid located between the pressurized valve and the base body 2 is collected in the container through the liquid passage 12 and the introduction pipe 4.

Nasal medication or drug delivery devices and methods for delivering adjustable or variable metered volumetric doses of medication or drugs to a nasal passageway of a user or patient. Relative movement between portions of a reservoir establish a set volume of medication for delivery. The delivery device may include a nosepiece for fitting into the nostril of the user or patient, a medication or drug reservoir or dosing chamber, and an external reservoir adapter for providing the medication from an external reservoir.

A fluid dispenser having a first fluid outlet for dispensing fluid when in a first orientation and a second fluid outlet for dispensing fluid when in a second orientation. An outlet valve mechanism directs the fluid towards the first fluid outlet in the first orientation, and towards the second fluid outlet when in the second orientation. The outlet valve mechanism includes a movable outlet member that is located at a first position when the fluid dispenser is in the first orientation, and is located at a second position when the fluid dispenser is in the second orientation.
