摘要:
A dosing device includes a dosing casing in one or more parts and with which are associated a pumping unit and a manually operable actuating unit, in which the dosing casing includes at least one dosing opening. The dosing casing has a jacket enveloping the pumping unit and on which is integrally shaped at least one actuating member mounted in elastically pivotable manner between a rest position and an actuating position.

A dosing device includes a body and an actuating element mounted in non-rotatable, liftable manner on the body. A counting device for the actuating strokes has a rotary counting ring forcibly coupled as a function of a lifting movement of the actuating element. A lock blocks the actuating element following a predetermined number of actuating strokes.The lock is associated with the counting ring in such a way that the latter can perform more than a complete revolution before the actuating element is blocked.
摘要:
An all plastic metering pump having a bellows-type spring with a tubular valve which is integrally formed on it in a single piece in a discharge region toward a metering head, the tubular valve being designed as a discharge valve of the metering pump. In the method, the pump components, which have been manufactured in each case in a plurality of injection cycles, are assembled from the injection mold in a defined assembly sequence in time with the injection cycles, the number of assembly steps corresponding to the number of injection cycles for producing the various pump components.

1. Dosing device for a medium. 2.1. A dosing device for a medium with an applicator housing, which has at least one discharge opening for dispensing the medium, with a pumping means, which has a pumping chamber arranged in the applicator housing, and with an elastically flexible membrane, which forms a wall portion of the pumping chamber and is arranged in an elastically movable manner in the applicator housing for changing a chamber volume of the pumping chamber and which is assigned on an outer side facing away from the pumping chamber an actuating surface for a manual pumping movement, is known. 2.2. According to the invention, the applicator housing has a flow path from the pumping chamber to the discharge opening, and the membrane forms an outlet valve of the pumping chamber. 2.3. Use for dosing media for cosmetic purposes.
摘要:
A discharge device for at least one medium has at least two media reservoir sections positioned rigidly relative to one another and which pass into one another in their interior through a step shoulder. The reservoir sections are formed by two separate hollow bodies that are superimposed over a portion of their length and are tightly interconnected.
摘要:
A dispenser (11) with an atomizing nozzle (15) contains a medium chamber (20) with the medium (24) to be discharged. The pump plunger (21) delivering the medium (24) is hydraulically operated by the pressure of a pressure fluid (25), which is manually applied by pressure on a pressure chamber (28) constructed as a squeezing bottle or bag. Several dispensers can be jointly manufactured and sold in chain form.

A disposable atomizer for discharging successive partial discharge amounts as a spray has a base body (12), a projecting nose adapter (13) with a nozzle (14), actuating shoulders (35) where two fingers can rest, and an actuating part, containing an actuating sleeve (25) and a medium store (20), which can be pressed into the base body (12). A hollow needle (17) can penetrate the closure piston-stopper (21) of said medium store (20). A ring (28) is mounted on the actuating sleeve (25) by spokes (29) and predetermined breaking points (30), the ring (28) separating in response to typical actuating pressure when the actuator is used the first time. The spokes (29) strike a stop which thus limits the first partial discharge stroke. By rotating the actuating sleeve (25), the actuating part is moved into a starting position for a second partial discharge stroke, and when intermediate webs in the form of material bridges are broken out, the second partial discharge stroke can be executed.

A dispenser (1) includes a traveling member (50) extending integrally from the pump piston (17) up to the nozzle body (49) of the medium outlet (20). The traveling member (50) is enveloped by a separate runner body (60) which has handles (62). A core body (30) is located within runner body (60) and extends over the entire length of the dispenser (1). The base body (4) to be secured to the reservoir (29) is composed from two interconnected components (8,9) which commonly bound a free space (80) for stress reliefing the piston lip (17) in the operational end position.
摘要:
A dosing device (17) for the medical administration of powder (16) through the nose or mouth has a valve body (27) which is movable in a discharge channel (22) between two valve seats (25, 26). During suction, the spherical valve body (27) is raised from the lower, container-sealing valve seat (26) and moved by a flow drag to the upper valve seat (25), so that it closes the discharge channel (22) and terminates dosing. The formation of the air/powder dispersion can be assisted in that the air subsequently sucked into the container is directed onto or into a powder supply or to a powder receiver in a pre-chamber fillable by tilting the device for pre-dosing.
摘要:
In a device (1) suitable for discharging media or the like at least one springly deformable component (5, 6, 11, 40) consists of a copolymer produced with a co-catalyst such as titanocen, more particularly an ethylene .alpha.-olefine copolymer which may also be improved as regards its resiliency by gamma irradiation.In a spiral spring (26, 39, 49) produced from this or a similar plastics material axially adjacent spiral sections are directly integrally connected to each other not only via the spiral but also along the circumference of the spring.
