Various exemplary drug syringes with a mechanical stop for a second dose, drug products utilizing the same, and methods of using drug syringes with a mechanical stop for a second dose are provided. In general, a nasal drug delivery device is configured to dispense therefrom first and second doses of a drug therefrom into a nose. The drug delivery device includes a mechanical stop configured to provide a pause between the delivery of the first and second doses. During the pause, a user of the drug delivery device can move the drug delivery device from one nostril, into which the first dose was sprayed, to another nostril, into which the second dose can be sprayed. The mechanical stop is configured to hold the drug delivery device in a static delivery state.

The device for dispensing medication for the treatment of pain, such as head or migraine pain, may comprise a medication applicator and an activator. The medication applicator may store a medication and may dispense the medication as an aerosol mist. The medication applicator may be adapted to dispense the medication through a nostril of a user directed at the posterior nasal cavity. The activator may be operable to release the medication in multiple doses. A first dose may be dispensed upon a first activation of an actuation button, and subsequent doses may be dispensed upon additional activations of the actuation button. Each dose may comprise a predetermined volume of the medication. A safety interlock may prevent premature dispensing of the medication. The invention may be adapted for the user to self-administer the medication while the user is positioned in any preferred physical position.

A fluid dispenser device comprising: a reservoir (10) containing one or more doses of fluid; a resilient element (20), such as a spring, for urging said reservoir (10) to move axially between a rest position and at least one actuated position; and blocking means (30; 51, 53, 55) for preventing said reservoir (10) from moving axially; said blocking means being movable manually in a direction that is different from the direction of said axial movement of the reservoir (10) so as to allow said reservoir (10) to move axially; said blocking means comprising a plate (30) provided with an opening (31) comprising a first opening portion (31a) of smaller size, and a second opening portion (31b) of larger size, said first and second opening portions (31a, 31b) being interconnected, said plate (30) being movable radially between a blocking position in which said first opening portion (31a) co-operates with said reservoir (10) so as to block it axially, and a non-blocking position in which said second opening portion (31b) co-operates with said reservoir (10) so as to allow said reservoir (10) to move axially under the effect of said resilient element (20).

A syringe-shaped spraying device includes: a barrel; a nozzle; a packing disposed therebetween; and a core disposed inside the nozzle. The nozzle is connected to a connecting portion provided at a front end of the barrel. The nozzle has a first facing surface facing a front end surface of the connecting portion and a second facing surface facing an outer circumferential surface of the connecting portion. The outer circumferential surface is provided with an annular recess portion, and the second facing surface is provided with a first annular protrusion portion and a second annular protrusion portion. By engaging the first annular protrusion portion with the annular recess portion, the packing is compressed in an axial direction by the front end surface and the first facing surface. The second annular protrusion portion is in pressure contact with the outer circumferential surface of the connecting portion entirely in a circumferential direction.

A fluid dispenser device having a body (1) with a dispenser orifice (2) and a perforator element (4), the body containing a reservoir (10) with at least two doses of fluid and having a proximal axial opening closed by a membrane (30) and a distal axial opening closed by a piston (20) to dispense one dose of fluid on each actuation. The reservoir is axially movable relative to the body between a rest position in which said perforator element does not pass through the membrane and a dispensing position in which the perforator element passes through the membrane. A perforator spring (6) is provided to urge the reservoir towards the rest position, and the membrane is adapted to close after each actuation, when said perforator element withdraws from the reservoir.

In an embodiment, a fluid container includes a container main body that has a tank housing a fluid; a fluid discharge body disposed on a front end portion of the container main body that discharges the fluid through a discharge port formed in a front end portion thereof; a plunger including an operating body that pushes out the fluid in the tank to the fluid discharge body in a predetermined amount corresponding to an operation of the operating body; and a valve that closes a connecting flow passage connecting the tank to the fluid discharge body and opens the connecting flow passage when the plunger pushes out the fluid, the valve including a valve seat surface, a valve body disposed in front of the valve seat surface to abut the valve seat surface from the front, and a spring biasing the valve body toward the valve seat surface.

A cartridge droplet dosage device with a cartridge (1) and an actuation element (2), whereby the cartridge (1) includes a reservoir body (3), a cladding (5) and a plug (6), characterized in that a fluid groove (9) projects from the reservoir body (3) into an inner tube valve area (11), whereby the fluid groove (9) is releasable either by the yielding of a sealing rib (12) and/or by the yielding of a part of the cladding (5).

A fluid dispenser device having a body (1) with a dispenser orifice (2) and a perforator element (4), the body containing a reservoir (10) with at least two doses of fluid and having a proximal axial opening closed by a membrane (30) and a distal axial opening closed by a piston (20) to dispense one dose of fluid on each actuation. The reservoir is axially movable relative to the body between a rest position in which said perforator element does not pass through the membrane and a dispensing position in which the perforator element passes through the membrane. A perforator spring (6) is provided to urge the reservoir towards the rest position, and the membrane is adapted to close after each actuation, when said perforator element withdraws from the reservoir.

Provided is a system and method for a vaporizer cartridge system wherein the cartridge provides the diffuser. More specifically, an embodiment of the system includes a vaporizing device providing a heating element proximate to a removable cartridge system receiving port, and a dispenser trigger structured and arranged to engage the removable cartridge to dispense a predetermined amount of a liquid concentrate from within the removable cartridge. The system further includes a cartridge with diffuser including: a housing; a reservoir of liquid concentrate; a diffuser element; a metered dispenser structured and arranged to dispense from the reservoir into the diffuser element a predetermined amount of liquid concentrate. An associated method of use is also provided.

In an embodiment, a fluid container includes a container main body that has a tank housing a fluid; a fluid discharge body disposed on a front end portion of the container main body that discharges the fluid through a discharge port formed in a front end portion thereof; a plunger including an operating body that pushes out the fluid in the tank to the fluid discharge body in a predetermined amount corresponding to an operation of the operating body; and a valve that closes a connecting flow passage connecting the tank to the fluid discharge body and opens the connecting flow passage when the plunger pushes out the fluid, the valve including a valve seat surface, a valve body disposed in front of the valve seat surface to abut the valve seat surface from the front, and a spring biasing the valve body toward the valve seat surface.
