Definitions

  • the invention relates to a dispenser for pasty products, consisting of a container open at the bottom with a dispensing opening and with a movable piston closing off the lower container opening and an actuating device arranged outside the container interior for manually pressing out the container contents by means of the piston through the dispensing opening, whereby the actuating device has a manually operable pushbutton, which cooperates with a restoring element and has a rod coupled therewith, projecting into the interior of the container, from a coupling device designed as a relative movement between the rod and the piston, which only allows unidirectional movement, to establish an operative connection between the by means of the Hand-operated organ up and down movable rod and the piston, and a device for preventing the piston from dropping from a position once reached.
  • connection device for establishing an operative connection in this known dispenser consists of four resilient tongues, two of which are diametrically opposed to each other.
  • the tongues are firmly attached at one end to the underside of the piston and each with their other ends directed obliquely downward and press with their end edges against the rod.
  • the device for preventing the piston from sinking from a position once reached likewise consists of four resilient tongues, diametrically opposed in pairs, which are each fixedly attached to the piston and are directed obliquely downward with the end edges of their other end and against the Press the inner wall of the container.
  • the push button which moves the rod downwards.
  • the piston remains stationary in position during this downward movement of the rod, since the tongues spreading into the container wall prevent a downward movement.
  • the actual conveying movement is brought about by the spring in the push button arrangement, since this pulls the rod upwards.
  • the tongues assigned to the rod expand into the lateral surface of the rod and thus couple the rod to the piston.
  • the tongues assigned to the inner wall of the container loosen from their spread position and graze along the inner wall of the container during the upward movement of the piston.
  • This known dispenser has the disadvantage that the tongues, which are all formed in one piece on a ring, must be designed very precisely in terms of their spring force and their dimensions, since otherwise an easy actuation of the dispenser is not possible. If e.g. If the springs assigned to the inner walls of the container have too great a spring force, it can happen that the spring in the push button is not able to lift the piston. On the other hand, if the spring length is not exactly adhered to, there is a risk that the rod pushed downward will move the piston downward as a result of the friction between the outer surface of the rod and the bore wall of the piston, since the tongue assigned to the inner wall of the container is too long due to its length cannot spread into the inner wall of the container. The corresponding disadvantages also arise if the tongues assigned to the rod have the errors listed above.
  • a dispenser for flowable materials is known from US Pat. No. 3,361,305, in which a container open at the bottom with a dispensing opening and with a movable piston closing off the lower container opening and an actuating device arranged outside the container interior for manually pressing out the container contents by means of of the piston are provided through the dispensing opening, but in this known dispenser the atmospheric pressure acting on the underside of the piston is used to move the piston upwards against a negative pressure to be created in a pumping chamber above the container interior and thereby to To convey donating material into the pumping chamber and from there to subsequently convey it outwards from the pumping chamber through the dispensing opening by means of the actuating device.
  • the piston is not mechanically coupled to the actuating device, and in particular not by means of a rod which can be connected to the piston by a coupling device when it moves upward.
  • check valves must be provided both at the transition from the interior of the container to the pumping chamber and at the dispensing opening from the pumping chamber to the environment, on the one hand to enable the formation of a negative pressure in the pumping chamber and on the other hand to transport material located in the pumping chamber outwards through the To ensure donation opening and to prevent the material in the pump chamber from being pushed back into the interior of the container.
  • a dosing device for liquid media in particular for a perm chemical, is known, which is designed as a liquid container with a dosing space downstream of it.
  • the interior of the liquid container is connected to the metering chamber via a connecting channel.
  • the dosing room is provided with a screen plate on its dispensing side, to which an application sponge is attached.
  • the connecting channel between the interior of the container and the dosing space can be closed by a sealing plug which is attached to the free end of a two-armed lever, which is pivotably mounted on a wall of the dosing space and whose other free end is provided with a handle protruding from the dosing space.
  • the sealing plug By actuating the handle, the sealing plug can either be lifted off the connecting channel or pressed onto it.
  • the transition of the chemical from the inside of the container into the dosing space is to be accomplished in that the dosing device is held in such a way that the dosing space connects under the container.
  • the sealing plug When the sealing plug is lifted off the connection channel, the chemical then runs down through the connection channel into the dosing chamber and from there through the sieve plate into the application sponge. After swiveling the sealing plug into the closed position, chemicals cannot flow into the metering chamber any further. The chemical in the application sponge can then be applied to the hair to be treated.
  • this known dosing device works at all, since a connection of the interior of the container to the atmosphere is not disclosed, no device is provided in this known dosing device by means of which the contents of the container are forced into the dosing chamber and from is promoted to the outside world.
  • no displaceable piston is provided in the interior of the container, the movement of which could promote the contents of the container to the outside.
  • the contents of the container should only flow outwards under the force of gravity after opening the connecting channel. Due to the lack of an actuating device which effects the conveyance of the container contents, this known metering device differs fundamentally from dispensers with forced conveyance of the container contents and in particular from dispensers of the type of the present invention.
  • a soap dispenser for dispensing pasty soap which has a soap container with a discharge screw rotatably arranged on the bottom inside and a discharge opening arranged at one end of the discharge screw.
  • a plate which essentially covers its cross section and has a central opening.
  • a threaded rod projects coaxially to the container, which is rotatably mounted in the container and which is also set in rotation by means of a gear mechanism when the discharge screw rotates.
  • the rotation of the threaded rod is converted into a downward movement of the plate in the container in that two claws are pivotably mounted on the plate diametrically opposite each other, each being designed as a two-armed lever.
  • each claw has teeth that can be brought into engagement with the thread of the rod.
  • the other free end of each rod is designed as a handle.
  • This claw arrangement is not a device for connecting a reciprocating rod to a piston always and only when the rod moves in one direction and not in the opposite direction.
  • the known device serves exclusively to produce a screw connection between the plate and the threaded rod that is permanently engaged during the operation of the device and not a coupling device that automatically detaches itself from the movement of a reciprocating rod in one direction of movement and engages again under the effect of gravity in the opposite direction of movement .
  • the invention has for its object to provide a dispenser of the type mentioned in the preamble of claim 1, in which the piston is prevented in a simple manner from falling from a position once reached and which is easy and reliable to handle.
  • the device for preventing the piston from sinking is designed as a check valve and in that the actuating device has a lever device by means of which the rod can be moved upwards when the push button is pressed.
  • the arrangement of a check valve and the arrangement of a lever device in the actuating device by means of which the rod can be moved upward when a push button is pressed, ensures reliable holding of the piston in a position once reached and prevents the piston from dropping out of this position and it is further ensured that when the actuating device is actuated, the piston is pulled up during the actuating process and thus the contents of the dispenser are dispensed during the actuation of the device and not in a subsequent process after actuation.
  • the result of the actuation is thus immediately visible and the amount donated can still be influenced during the donation by a corresponding observation of the amount of the escaping material by a correspondingly dependent dosage of the actuation movement.
