Abstract: A paint-spraying device for generating a paint spray jet, wherein the paint-spraying device comprises a front end and a back end, wherein the front end and the back end are connected to one another such that they can be separated by virtue of the back end and the front end being pulled apart, wherein the paint-spraying device comprises a paint container, wherein the paint container comprises an air feed line that leads into the paint container, wherein the air feed line comprises a check valve, wherein the paint-spraying device comprises an air discharge line that is connected to the paint container, and the air discharge line comprises a shut-off valve by means of which the air discharge line is closed off during the operation of the paint-spraying device.

Abstract: A paint nozzle assembly for a paint spraying device for creating a paint spray jet. The paint nozzle assembly comprises a needle, a nozzle body and a seal. The nozzle body comprises a nozzle opening, a paint feed and a needle guide. The seal subdivides an interior enclosed by the nozzle body into an antechamber and a paint chamber. The seal is connected fixedly to the needle, and the seal is in the form of a membrane seal and is connected fixedly to the nozzle body. The interior comprises a diverging portion as far as the needle guide.

Abstract: A dispenser includes a housing and a discharge opening provided at the distal end of the housing. The dispenser includes a liquid reservoir and a control device having a pump or a switching valve, which control device is connected by a first line to the liquid reservoir and by a second line to the discharge opening, and via which control device liquid is conducted from the liquid reservoir to the discharge opening. The dispenser includes a push button provided laterally in a cutout of a circumferential face of the housing and connected to the control device such that pressing the push button actuates the control device so that liquid is conducted to the discharge opening. Measures for securing the dispenser include a rotatable sleeve over the push button, a secured cap, a securing arrangement on the push button, an interaction of the push button with an opposite side of the dispenser, and a receiving sleeve for the dispenser.

Abstract: A liquid dispenser for discharging cosmetic or pharmaceutical liquids, in particular in the form of an inhaler. This liquid dispenser includes a switchable valve mechanism, a base, and a discharge head which, for actuation of the valve mechanism, is movable with respect to the base in a superposed axial and rotational movement or in a rotational movement between an opening position, in which the valve mechanism is opened, and a closure position, in which the valve mechanism is closed. It is proposed that, in a delivery state of the liquid dispenser, a rotational movement of the discharge head with respect to the base is blocked by a tamper-evident portion that is separable from the dispenser.
