Systems, devices, and methods are disclosed for pen that distributes viscous plant material, such as rosin, from a cartridge. The pen receives, from a button, input corresponding to a first control instruction. The pen has a motor configured to receive the first control instruction from the controller and, in response, drive a spindle that linearly displaces a plunger, wherein the linear displacement of the plunger causes plant material to be pushed out of a nozzle of the pen. The pen cartridge includes a rubber plug configured to be linearly displaced by the plunger to cause rosin to be disturbed from the cartridge.

The invention relates to a device for applying a viscous substance, in particular for cosmetic, writing, painting, drawing and/or marking purposes, having a tank for the substance, an applicator and a conveyor designed to convey the substance from the tank to the applicator. According to the invention, the conveyor has a cylinder, a first and a second closing device, which are both arranged in the cylinder in an axially displaceable manner, a pump tappet for axially displacing the closing devices, a first connecting channel between the cylinder and the tank and a second connecting channel between the cylinder and the applicator, the first closing device opens or closes the first connecting channel depending on its position relative to the cylinder, and the second closing device is adjustable relative to the pump tappet, opens or closes the second connecting channel depending on the position relative to the pump tappet and, together with the cylinder, forms a pump in which it serves as a piston.

A fluid dispenser assembly comprising a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62), the fluid reservoir (4) including a piston (42) that is movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir, the dispenser assembly being characterized in that it further comprises an RFID tag (40) that is secured to the piston (42).

A fluid dispenser having a casing (E) provided with a dispenser head (11); and a refill cartridge (C) that includes a fluid reservoir (R). The refill cartridge (C) is axially insertable into the casing (E) in such a manner as to connect the fluid reservoir (R) to the dispenser head (11). The refill cartridge (C) and the casing (E) are provided with a connection mechanism (17, 253) that connects the refill cartridge (C) in the casing (E) by screw-fastening, so as to bring the fluid reservoir (R) into leaktight contact with the dispenser head (11). The movement, after screw-fastening, of the refill cartridge (C) in the casing (E) towards the dispenser head (11) delivers the fluid to the dispenser head (11).

A fluid dispenser assembly having a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62). The fluid reservoir (4) includes a piston (42) movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir. The dispenser assembly further includes an RFID tag (40) that is secured to the piston (42).

A fluid dispenser having: a fluid reservoir (1); an applicator (2); and a dispenser module (3) that is arranged between the reservoir (1) and the applicator (2); the fluid dispenser being characterized in that the dispenser module (3) includes an air pump (4) for sending air into the reservoir (1), and a fluid duct (54) connecting the reservoir (1) to the applicator (2).

A device for transferring liquids and liquid samples in certain quantities includes a housing, a pressing unit, a liquid extraction assembly, and a connecting member. The pressing unit includes an extrusion portion. The housing includes a first sidewall and a second top wall. The first sidewall and the second top wall cooperatively define a receiving cavity. The pressing unit is received in the receiving cavity. The liquid extraction assembly includes a liquid extraction pipe. The liquid extraction assembly is detachably connected to the housing through the connecting member. The pressing unit can move back and forth along the central axis of the receiving cavity, so as to move the extrusion portion back and forth relative to the liquid extraction pipe. The liquid extraction pipe is deformed by the extrusion portion to take up or release liquid in precise quantities.

A fluid dispenser having a reservoir (R) containing fluid (P) and air (A), the reservoir (R) forming an assembly opening (11); a fluid dispenser cannula (12) in communication with the reservoir (R); and an actuator member (2) engaged in the assembly opening (11), for supplying the dispenser cannula (13) with fluid (P). The actuator member (2) has a deformable membrane (23) that defines an outside face (231) forming a pusher (24), and an inside face (232) that is in contact with the air (A) of the reservoir (R), when the dispenser cannula (12) is in contact with the fluid (P) of the reservoir (R).

A replenishable dispenser for dispensing a liquid product. The replenishable dispenser comprises a housing, a canister for storing the liquid product, a triggering unit, an application member and a suction assembly for dispensing the liquid product from the canister to the application member upon being actuated by the triggering unit. The canister is detachably connected to the housing to replace the canister upon being exhausted with a new canister to replenish the dispenser. The dispenser further includes an applicator tip detachably connected to a holding unit of the application member.

A dispenser and applicator head (T) for associating with a dispenser unit (P), such as a pump, and defining a longitudinal axis X, and a front face (f1) and a rear face (f2) on either side of the longitudinal axis X, the dispenser and applicator head (T) comprising a dispenser member (1) and an applicator pad (4), the dispenser member (1) defining a feed path (C) for connecting the dispenser unit (2) to a dispenser orifice (O), the applicator pad (4) being mounted on the fluid dispenser member (1), adjacent to the dispenser orifice (O); the dispenser and applicator head being characterized in that the dispenser orifice (O) is arranged axially on the longitudinal axis X, above the applicator pad (4) that extends mainly over the front face (f1).
