Abstract: A dispensing device for dispensing a fluid includes a head base piece having a dispensing opening, a liner arranged inside of the head base piece, a liner channel that is arranged between the head base piece and the liner, and a valve element that is movably arranged, at least in regions, inside of the liner and interacts with the dispensing opening. The valve element can be transferred from a first position into a second position via a stroke relative to the liner. In the second position of the valve element, a fluid path is formed between the liner channel and the dispensing opening, whereby a dispensing of fluid is rendered possible. A dispensing of fluid in the first position of the valve element is thereby prevented with a low number of components in that the liner channel is sealed against the dispensing opening by the liner.

Abstract: A dispensing device for dispensing a fluid has a head base piece having a dispensing opening, a liner arranged inside of the head base piece, and a valve element movably arranged inside of the liner. The valve element is arranged to be movable from a first position into a second position via a stroke relative to the liner. The valve element closes off the dispensing opening in the first position and clears the dispensing opening in the second position. The valve element and the liner, which seal against one another in the first position and in the second position, form a nozzle chamber and a valve chamber. The dispensing device includes a channel, which connects the valve chamber and the nozzle chamber to one another, enables the use as a spray device.

Abstract: Childproof safety cap has two opposite bead-like threads on its inner wall. Each thread has a widened end region, a stop surface thus being formed. The associated bottle has two opposite groove-like threads on a connecting piece of the bottle, each of which threads has a widened region in the end region, an undercut thus being formed in the groove by the widened region. When the safety cap is screwed on, the stop surfaces on the two bead-like threads hook in behind the undercuts on the groove-like threads. The stop surfaces can be released from each other only if the safety cap is pressed down toward the bottle onto the connecting-piece neck. Connecting-piece neck forms a slipping surface that conically expands downwards. The safety cap can then be unscrewed while simultaneously being rotated.

Abstract: Dispensing device for a fluid and method for dispensing fluid from dispensing device. Dispensing device includes a fluid channel; a chamber arrangement including at least one sealing element; a dispensing opening; a valve element configured to be movably disposed within the chamber arrangement and to interact with the dispensing opening; and at least one sealing element, arranged within the chamber arrangement, that is configured to create a seal against the valve element during a first predetermined stroke of the valve element.

Abstract: Dispensing device and method for dispensing fluids from a fluid container. The dispensing device includes an attachment section, a first blocking section, a second blocking section, and an actuating section. A dispensing of the fluid results from actuation of the actuating section and the actuation of the actuating section is blockable by a rotation of at least one of the first blocking section and the second blocking section with respect to the attachment section.

The bottom (7) of the outlet hood (1) has a uniform thickness and is provided with outlet openings (8) which diverge relative to each other. The bottom of the outlet hood (1) is outwardly arched and the outlet openings (8) have a uniform cross section over their entire length which corresponds to the thickness of the bottom (7), and the outlet openings (8) are arranged distributed over the bottom (7).

Abstract: A double-acting pump for ejecting a product from a container includes a piston which is axially slideable in a housing and is sealed by the housing. A hollow piston rod extends the axial bore of the piston and is slideable in a closing cap and has an actuating head, wherein, when the actuating head is actuated, the piston builds up a pressure in a pressure chamber against a restoring force of a spring. An outlet duct extends through the actuating head to an outlet opening. When subjected to the restoring force of the spring, the piston releases a passage between the pressure chamber and openings of a second housing portion. A medium which kills germs and bacteria is arranged in an expansion chamber. The dispensing stroke volume of the piston corresponds to the volume of a drop of the liquid.

Abstract: An actuating head (12) of a double-acting pump (1) for ejecting a product (38) from a container (2) includes an outlet duct (13a-13d) leading to an ejection opening (16), wherein a closing piece (18) biased by a spring (17) is arranged in the outlet duct. The closing piece (18) directly seals the ejection opening (16) under the force of the spring (17) and the closing piece (18) releases as a result of the pressure exerted when actuating the double-acting pump (1) the flow of the product (38) through the outlet duct (13a-13d) and through the ejection opening (16) against the force of the spring (17).

When an actuating head is actuated, it presses the piston against the force of a restoring spring toward a connecting pipe portion for an immersion pipe provided in the housing, so that a pressure is built up in a pressure chamber of the housing which presses a first valve closing piece in the connecting pipe piece against a first valve seat.

Abstract: A actuating head of a double-acting or lift and force pump for ejecting a product from a container includes an outlet duct leading to an ejection opening, wherein a valve closing piece is arranged in the outlet duct. Together with the outlet duct, the valve closing piece forms a check valve which, when the actuating head is actuated, is opened by the pressure of the product and allows the product to flow into a space defined by the inner side of the outlet duct and the circumference of the valve closing piece. This space is connected through at least one transverse groove to the ejection opening. The valve closing piece is elastically deformed by the product pressure when the actuating head is actuated and opens the check valve. The valve closing piece borders against the transverse groove and rests with its rear side against a radially inwardly protruding shoulder of the outlet duct.
