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.

Provided is a pump for discharging cosmetics to the outside while simultaneously opening the outer vessel lid and pushing the discharge plate, which is formed of a smaller number of parts, and thus it is possible to reduce the manufacturing cost.

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 hollow cannula (4) including a perforating tip (5) for perforating a perforating site, said perforating tip (5) being provided with an opening (6), said opening (6) defining a peripheral edge (7) that extends around said opening (6) and that includes a distal axial end and a proximal axial end, said distal axial end of said peripheral edge (7) forming the distal axial end (59) of the perforating tip (5), said distal axial end (59) of the perforating tip (5) being arranged on the longitudinal central axis (A) of said cannula (4), said perforating tip (5) having an outer shape that is rounded in the radial direction, and said distal axial end (59) of said perforating tip (5) being of shape that is rounded in the axial direction.

A fluid dispenser device having a body (1), and a dispenser head (2) provided with an orifice (3) and that is axially movable relative to the body (1). The body receives a reservoir (10) containing fluid, the reservoir has a hollow tube (11) having a proximal axial opening (12) closed by a stopper (20) adapted to slide in the tube (11). The dispenser head (2) includes a hollow cannula (4) connected at one end to the dispenser orifice (3), and provided at its other end with a perforating tip (5) having an opening (6) for perforating the stopper (20), the opening (6) defining a peripheral edge (7) extending around the opening (6) and includes a distal axial end and a proximal axial end, the distal axial end forming the distal axial end (59) of the perforating tip (5) arranged on the longitudinal central axis (A) of the cannula (4).

A syringe is provided, the syringe includes a rod side member having a lock part configured to be locked to the rod in the first state; a first pushing part configured to be pushed against the rod toward the distal side in the first state; and a second pushing part configured to be pushed against the rod toward the distal side in the second state; the rod including a first lock part; a first pushed part; and a second pushed part, the barrel side member including: a lock-release part configured to release lock between the lock part and the first lock part of the rod with the rod pushed to the predetermined position in the barrel in the first state.

Provided is a metered quantity syringe-type dispenser that is capable of multistage pushing. The metered quantity syringe-type dispenser includes a syringe; a plunger configured to be pushed into the syringe; an elastic deforming portion configured to be deformed in response to the pushing of the plunger; and a stopper portion configured to be locked with respect to the syringe and to be released from the locking by restoring force of the elastic deforming portion.

A fluid dispenser device having a body (1), and a dispenser head (2) provided with an orifice (3) and that is axially movable relative to the body (1). The body receives a reservoir (10) containing fluid, the reservoir has a hollow tube (11) having a proximal axial opening (12) closed by a stopper (20) adapted to slide in the tube (11). The dispenser head (2) includes a hollow cannula (4) connected at one end to the dispenser orifice (3), and provided at its other end with a perforating tip (5) having an opening (6) for perforating the stopper (20), the opening (6) defining a peripheral edge (7) extending around the opening (6) and includes a distal axial end and a proximal axial end, the distal axial end forming the distal axial end (59) of the perforating tip (5) arranged on the longitudinal central axis (A) of the cannula (4).

A fluid dispenser device comprising: a reservoir (10) containing at least two doses of fluid; a dispenser member (20), such as a piston, that is mounted to slide in said reservoir (10) so as to dispense the fluid; a dispenser head (30) that is provided with a dispenser orifice (31), said head being movable relative to said reservoir (10) so as to move said actuator member (20) in said reservoir (10) and thus dispense the fluid through said dispenser orifice (31); said dispenser head (30) including at least two viewing windows (35, 36), said device including an indicator (40) that is movable together with said reservoir (10), said indicator (40) co-operating with a respective viewing window (35, 36) after each actuation of the device.

A fluid product dispenser comprising a tank and a metering device mounted on the tank, the metering device having a chamber defining an inlet, an abutment, an outlet and a sealing seat, the abutment separated from the sealing seat by a stroke distance; a valve movable inside the chamber over the stroke defined between a rest position, in which the valve is biased by a return force towards the abutment, and an end position, in which the valve is selectively urged onto the sealing seat against the return force by the fluid flowing in the chamber from the inlet to the outlet; and a mechanism for adjusting the stroke of the valve capable of adjusting the stroke distance separating the abutment from the sealing seat. The adjustment mechanism is located in the fluid tank, so that they are inaccessible and cannot be actuated from outside the fluid product dispenser.
