Definitions

  • the invention relates to a dispenser for liquids or pasty products, of the type specified in the preamble of claim 1.
  • the first check valve at the opening in the partition between the interior of the container and the pumping chamber requires a relatively large outlay in terms of production technology. If entire check valves are manufactured and installed as a separate unit, this is complex in design, manufacture and assembly and is associated with great costs.
  • closing parts of check valves in particular in the form of closing flaps, are designed as components of inserts to be arranged in headpieces of dispensers, which also have other functions, for example the formation of the pumping chamber and the formation of a conduit to the applicator, arise for the production, especially in the plastic injection molding process, complicated and expensive injection molds.
  • the preamble of the new claim 1 is based on the cited EP-A-0013691.
  • the dispenser for pasty products described in FIGS. 3 to 8 of this prior publication has a one-piece injection molded part which at the same time has the elastic flaps for the first check valve and the second check valve.
  • This unit which consists of a closing part, an elastic element and a holding element, forms a connecting tunnel which connects an output channel to a section of the pump chamber.
  • the invention is therefore based on the object of providing a dispenser of the type described at the outset, which is simple and economical to manufacture with regard to the first check valve, and in which a reliable function of the first check valve is ensured.
  • the closing part of the first check valve can be produced together with a holding element and at least one elastic element connecting the closing part with the holding element as a simple component, for example using a simple injection mold, and then as an insert on the partition in the area of the opening or openings be attached.
  • a simple component for example using a simple injection mold
  • an insert on the partition in the area of the opening or openings be attached.
  • each opening in the dividing wall is followed by a suction tube which extends into the container and is open at the bottom, that the container at its lower end is connected to the walls bottom of the container is closed, and that in the region of the dividing wall at least one connecting path connecting the inside of the container with the surroundings is provided, optionally with a device preventing the contents of the container from escaping to the outside.
  • a suction tube which extends into the container and is open at the bottom
  • the container at its lower end is connected to the walls bottom of the container is closed
  • in the region of the dividing wall at least one connecting path connecting the inside of the container with the surroundings is provided, optionally with a device preventing the contents of the container from escaping to the outside.
  • the second check valve closes and a negative pressure is created in the pump chamber, by which the first check valve is opened and liquid is sucked up from the interior of the container through the suction pipe or the suction pipes into the pump chamber. Since the area of the interior of the container above the liquid is connected to the environment via a connecting path, for example a narrow connecting channel, the pressure of the environment prevails there.
  • the container has an opening at its lower end and is closed there with a piston which seals the inner wall of the container.
  • the pressure of the environment acts from the outside on the piston sliding on the inner wall of the container and moreover on the contents of the container. If the volume of the pump chamber is reduced by external actuation, the pasty material located therein is pressed outwards by the second check valve and the applicator mouth. The first check valve is closed. If the volume of the pumping chamber is then increased again, the second check valve closes and a negative pressure is created in the pumping chamber, by which the first check valve is opened. Under the effect of the ambient pressure pressing on the displaceable piston from below then pasty material is pressed through the first check valve into the pump chamber.
  • a particularly advantageous embodiment of the dispenser according to the invention which can be used both for liquid products and for pasty products, is achieved according to the invention in that the head piece has a pump element that can be actuated from the outside and is displaceable relative to the partition wall, for changing the volume of the pump chamber, on which one the restoring spring causes the restoring movement away from the partition and the applicator of the head piece has an output channel which is laterally offset to the opening or the openings of the partition.
  • the volume of the pump chamber is reduced by manually pushing the pump element inward. An increase in the volume of the pump chamber is then automatically brought about by the return spring pushing the pump element outwards.
  • a very favorable embodiment of this embodiment of the invention is provided in that an insert is arranged in the head piece, which has an upwardly and downwardly open hollow cylindrical part to form a substantially cylindrical pumping chamber and a part connecting the pumping chamber to the applicator, and in that the pump element, which can be actuated from the outside, is designed as a pump piston which is displaceably guided in the hollow cylindrical part of the insert.
