Definitions

  • the invention relates to a dispenser for discharge of liquid to pasty materials comprising a pump head and a pump chamber formed in the pump head, the pump chamber having a pump chamber wall and an inlet valve and an outlet valve, and the dispenser comprising a storage container, a storage bag which can be reduced in volume for the purposes of discharge being contained in the storage container.
  • Dispensers of this kind are already known in a multiplicity of configurations. For example, reference is made to FR-A1-2 647 418 or DE-A1-34 42 092.
  • the pump chamber wall is flexible. Because of such a flexible pump chamber wall, it is possible in the case of a dispenser of the kind previously described for pressure oscillation to be averted, at least to a certain degree. For example, a loading or pre-loading of the outlet valve can in addition be adjusted such that in comparison with the elasticity of the pump chamber wall, a pressure spike can be absorbed in the pump chamber wall practically completely or in any case to a very great extent.
  • This configuration is in particular also advantageous in the case when the inlet and outlet valve in the inactive condition of the dispenser do not definitely shut off, this being usually the case. Because of cohering in the material in the unactuated condition, this may occur.
  • a non-return valve as is generally used as inlet valve for the pump chamber, is not always closed after use of the dispenser, in particular for highly viscous media. This is because after a dispensing stroke of a dispenser, there follows the suction phase, during which product is sucked out of the storage container into the pump chamber while the pump chamber inlet valve is open. The valve is opened accordingly. In particular also in connection with such high viscosity media, there results therefore a direct transfer from the storage container into the pump chamber, so that the pressure fluctuations mentioned may under certain circumstances act in a correspondingly negative manner.
  • a certain improvement can optionally be achieved by an elastically formed inlet valve being provided, in particular also by an inlet valve being provided which is preloaded into its closed position, the valve being in this case only elastic by way of example.
  • the pump chamber may be formed by a pump bellows, as is for example described in principle with regard to the pump chamber wall in DE-U1-87 02 705 or DE-86 29 681.
  • the disclosure content of these specifications is hereby incorporated as to its full content also in the disclosure of the present application, including for the purpose of incorporating features of the specifications taken into consideration into claims of the present application.
  • the pump chamber wall on account of its elastic return force, to replace an otherwise necessary return spring.
  • the inlet valve which is preloaded into its closed position consists, preferably also as a whole, of an elastic plastics material. This is possible because of the special configuration of the inlet valve in the form of a part which is double cup-shaped, or inwardly hollow and widening in stepwise manner toward the top.
  • the sealing is effected by way of an outer peripheral edge of the part insofar as it has a circular cross section, at a step transition.
  • a centering column may extend also from the lower base of the inlet valve, which is directed toward the pump chamber.
  • the preloading of the inlet valve and/or of the outlet valve into the closed position means that it is not necessary for it to engage with preload against the closure wall.
  • this may also mean that closure may be only approximate, but a gap is optionally left free.
  • This may also be advantageous with respect to a continuous connection between the material in the pump chamber and the storage container for, for example, longer periods of non-use.
  • the inlet valve which is preferably formed in an integrated manner into the pump bellows has in detail a bridge portion, which consists preferably of a soft plastics, as for the remainder of the pump bellows as a whole.
  • a sealing lip may extend once again circumferentially from this bridge portion, the sealing lip interacting with a counter sealing portion on the telescopic outer part.
  • FIG. 1 shows a cross section through a dispenser, cut along the longitudinal axis a-a in FIG. 2 , in FIG. 3 ;
  • FIG. 2 shows a cross section through the dispenser, cut along the transverse axis b-b in FIG. 3 ;
  • FIG. 3 shows a top view of the dispenser according to FIG. 1 and FIG. 2 ;
  • FIG. 4 shows a cross section through the pump head, cut along the longitudinal axis c-c in FIG. 6 ;
  • FIG. 5 shows a representation corresponding to FIG. 4 , cut along the transverse axis d-d in FIG. 6 ;
  • FIG. 6 shows a top view of the dispenser head according to FIG. 4 and FIG. 5 , with the covering cap removed.
  • a dispenser 1 consisting of a pump head 2 and a storage container 3 .
  • a substantially loose internal bag 4 in which the substance to be dispensed is contained.
  • the internal bag 4 can be connected to the base in the base region of the storage container 3 , either in a pointwise manner or along a line, so that turning inside out of the internal bag is prevented.
  • the internal bag 4 is furthermore secured to the storage container 3 in the neck region 5 of the container.
  • the pump head 2 is formed in modular manner and can be introduced from above into the storage container 3 .
  • the connection between the storage container 3 and the pump head 2 is achieved by means of an adaptor part 6 , which because of the round implementation of the pump head 2 , respectively the telescopic outer part 15 and the telescopic inner part 10 , is shown differently in the cross sections according to FIGS. 1 and 2 .
  • the adaptor portion 6 forms a step region 16 , which in the transverse axis b-b, see FIG.
  • the latching or clamping connection between the adaptor part 6 and the storage container 3 is partially effected, in the region of the step surface 16 , by a separate latching wall 18 , which co-operates with the associated neck region 5 of the storage container, the neck region being formed for latching.
  • the wall 17 In the region of the transverse axis b-b, the wall 17 however takes over this co-operation, the wall 17 forming to this extent also an individual latching bead 19 , see FIGS. 2 and 5 .
  • the pump head 2 has a pump chamber 8 which consists of a flexible pump bellows 20 .
  • the pump bellows 20 is formed to extend in vertical cross section in a zigzag manner, but as against this, as can be seen from a horizontal cross section, is formed to be fundamentally circular.
  • Formed integrally in the pump bellows at the foot is a part 9 of an inlet valve, the opposing co-operating part for which is integrated into the telescopic outer portion 15 of the pump head 2 .
  • the pump head 2 has a telescopic inner part 10 , both parts telescoping with one another outside the pump chamber 8 .
  • the telescopic outer part 15 forms an encircling supporting socket 21 , in which the foot region of the pump bellows 20 is seated at its lower end; this specifically in co-operation with an inner surface of the supporting socket 21 .
  • the pump bellows 20 is no longer formed in bellows-like manner, but rather with a solid wall, which has a strengthened triangular cross section in the region in which it engages over the supporting socket 21 .
  • the pump bellows is seated at its lower end on the base 24 of the telescopic outer portion 15 , on the inside.
  • the base 24 defines a central opening 25 as delivery channel to the inlet valve 26 , which is narrowed with respect to the base 24 toward the interior of the pump chamber 8 .
  • the channel ends in two concentric rings 27 , 28 , of which the outer surface of the ring 27 is formed for sealing co-operation with a lip 29 of the bridge part 9 of the inlet valve 26 .
  • outlet valve 11 formed of a yieldingly elastic plastics material. This is seated in a seating part 12 , which holds the upper collar 14 of the bellows or the pump chamber wall, by clamping the collar in between the part 12 and a cooperating counter retaining part 13 .
  • the counter holding part 13 has a lower portion 29 which projects into the fold region of the pump chamber 8 , the lower portion being formed to be basically cylindrical, and at its lower end is also still in the form of an inner double wall, which has a guide portion 30 formed over a partial portion of the portion 29 , in which portion 30 the seating part 12 is guided.
  • the seating part 12 ends at the bottom, for example with the lower end of the guide part 30 .
