A dispensing device as well as a dispensing head and use thereof are proposed. Through depression of the dispensing head, an associated dispensing valve is opened and the product to be delivered can escape or be dispensed through an outlet space and via a downstream outlet valve. In order to prevent or at least minimize subsequent dripping or foaming, the volume of the outlet space is initially reduced upon actuation of the dispensing head and enlarged again upon completion of actuation, particularly after closing of the dispensing valve, whereby the product is suctioned away from the outlet or outlet valve back into the outlet space.

Dispensing head and dispensing device

A dispensing device for a preferably cosmetic liquid as well as a method for the manufacture thereof are proposed. A lasting and tight joining of two materials is achieved while allowing for simple manufacture by pretreating the surface of the first material by means of plasma treatment or irradiation in a desired joining area in order to form radicals there or to break up the polymer chains of the first material, and by then injecting the second material directly against the first material. Another aspect consists in covering the first material with a second material for joining with another material or component.

Dispensing device

The invention relates to a dispensing device, particularly a dispensing head proposed for preferably cosmetic liquid. A simple, tightly closing structure of an outlet valve is achieved in that a valve element is injected onto a wall and/or lies thereon with its entire surface or flat surface when the valve is closed and/or the valve element covers an outlet opening on the flat side. Alternatively or in addition, the valve element is pretensioned into a closed position when the valve is closed.

What is being proposed is a dispensing device for a preferably cosmetic liquid and a manufacturing method. A first material is pretreated in areas through the application of a coating or embossing foil such that a second material which is injection-molded directly against it does not bond with the first material in the pretreated area but rather can be detached again.

Proposed are an outlet valve and a dispensing device with an outlet valve for a cosmetic liquid. The outlet valve has a flatly resting valve element with an outlet formed therein. The outlet valve is able to open through the elastic deformation of the valve element.

Valve and discharge device

A dispensing device for dispensing a preferably cosmetic fluid is proposed. The dispensing device has an elastically deformable section for pumping a fluid. Simple and easy actuation is made possible by the section having a concave region in the initial position and/or by the thickness of the section varying.

Disclosed is a device () for dispensing a liquid () without spraying as well as a use of such a dispensing device (). In order to prevent liquid from escaping after a dispensing process, an outlet that opens towards the environment can be closed by means of a discharge valve (). Said discharge valve () is provided with a valve body () which can be moved in accordance with the prevailing liquid pressure such that the discharge valve () opens when a minimum pressure is exceeded.

A dispenser pump () that has a manually insertable pump shaft () which is surrounded by at least three sleeve sections () that can be slid into each other in a telescopic manner. A return spring () is preferably disposed between pump shaft () and the sleeve sections (). All parts of the dispenser pump (), which enter in contact with a liquid that is to be pumped, are made of plastic.

A metering valve () and a device () provided with it for metered dispensing of a preferably cosmetic liquid () and a process for producing such a metering valve and a use of such a metering valve. The metering valve preferably has a sealing element () which is injection molded onto the valve element () or a valve housing () or attached in some other way so that simple and economical production by injection molding is enabled. Optimum sealing is achieved in that the sealing element, at least in sections, is made at least annular or sleeve-shaped, seals radially with the inlet valve closed, and is supported either radially inside or outside.

Metering valve and device for dispensing a preferably cosmetic liquid

A metering valve () and a device () provided with it for metered dispensing of a preferably cosmetic liquid () and a process for producing such a metering valve () and a use of such a metering valve () are suggested. The metering valve has a valve element () with a spring section () which is elastic in the direction of motion and which bears a sealing element (). This allows especially sealed contact with the assigned valve seat when the inlet valve () is closed.

The invention relates to an adapter () for a manually operated dispensing device () for a fluid that is/can be pressurized in a container. The dispensing device includes a housing () having a passage channel (). A tubular adapter housing () connects the uptake tube () and the channel () of the housing () of the dispensing device (). The adapter housing () has a connecting sleeve () for connection to the connecting nipple of the housing () and an uptake tube sleeve () for connection to the uptake tube (). There are several inlets () for the fluid in the upside down position of the dispensing device. The adapter housing () defines at least one section of the inlets. An inlet valve () is defined within the adapter housing () for releasing the inlets substantially simultaneously when a pressure acts on the fluid in the container in the substantially upside down position of the container. A shut-off valve () is positioned inside a large diameter valve chamber () of the adapter housing (), in such a way that the valve () can be freely displaced axially between two end positions.

A foaming head (10) has a discharge nozzle (12), the discharge channel (14) of which has at the upper end a tubular section (16), the upper end of which is closed by a deflecting plate (18) and is provided with passage slits (22) which open out radially into an outlet slit (24) in the head wall (20). An inner base (26) of each outlet slit (24) extends radially outwardly from the lower end (28) of each passage slit (22) as far as a deflecting wall (30) which together with the discharge channel (14) forms an acute angle which opens towards the head wall (20). An upper end (32) of each deflecting wall (30) is arranged at a level which is approximately two-thirds of the height of the tubular section (16). An outer base (34) of each outlet slit (24) extends radially outwardly from the upper end (32) of the deflecting wall (30) as far as the vicinity of an outer edge (36) of the head wall (20). The foaming head can be produced economically as a one-part plastics injection molding and, with an extremely simple construction, permits outstanding foaming of a foamable product contained in a pressure container.
