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.

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.

The invention relates to a spray head for a device for dispensing a fluid product, having a body provided with a spray orifice, a central channel being connected to the spray orifice via a spray profile having a vortex chamber arranged directly upstream of the spray orifice, the spray profile having at least two curved channels extending from the central channel to the vortex chamber, each curved channel connected non-radially to the vortex chamber, to form a spray exiting the spray orifice, each curved channel having a convex shape, diverging laterally outwards from the central channel, and then from an inflection point, returning laterally inwards towards the vortex chamber.

A piston for use in a cartridge for dispensing multi-part fluids, the piston being injection molded and having integrally formed circumferential seals, wherein the piston is molded in the absence of a longitudinal parting line across the seals. A tool for forming a piston having a plurality of circumferential seals for use in a cartridge for dispensing multi-part fluids, the tool comprising a plurality of segments together defining a piston cavity corresponding to an outer periphery of the piston.

A dispenser for containing and dispensing substances such as fluids, viscous substances and/or adherent substances. The dispenser has a flexible bag adapted to contain a substance to be discharged, and a one-way output nozzle that is in sealed communication with the interior of the bag for discharging the contents of the bag. The dispenser has a receptacle, with the bag being arranged and sealed within the receptacle thereby trapping fluid between the exterior of the bag and the receptacle. The nozzle of the dispenser is arrangeable on a surface of the receptacle and there is additionally a one-way fluid intake valve arranged on the receptacle for intaking fluid into the receptacle and around the exterior of the bag. The dispenser further has an arrangement for preventing the bag from blocking the nozzle. The contents of the bag can be emptied through the nozzle without the bag blocking the nozzle in use.

A discharger includes a dispensing element and a housing, the housing having a static piston connected to the dispensing element at least in a fluid conducting manner and with the static piston being arranged within the housing. The further includes a container containing a fluid, the container being moveable relative to the static piston and the housing, with the static piston including a piercing tip adapted to pierce a membrane or seal of the container when the container is moved towards the housing.
