Definitions

  • the present invention relates to a device for dispensing liquid or paste products from a container, said device comprising a pump housing connected to an opening in the container and provided with inlet and outlet valves, which pump housing consists of a sleeve-like portion made in one piece of elastic material, preferably rubber, and which valves are also made of an elastic material, preferably rubber, and have a sleeve-like shape with a membrane at one end.
  • the present invention achieves a pump device in which the above mentioned disadvantages have been completely eliminated.
  • the pump device according to the invention is even so simple and inexpensive that it is suitable as a disposable product.
  • the characterizing features of the invention are revealed in the attached claims.
  • Fig. 1 shows a longitudinal section through the pump device itself.
  • Figs. 2 and 3 show views from above of inlet and outlet valves respectively, in the device according to Fig. 1.
  • Figs. 4 and 5 show two different side views of a screw cap.
  • Figs. 6 and 7 show two different views of a button.
  • Fig. 8 shows the button according to Figs. 6 and 7 mounted on the cap according to Fig. 5.
  • Figs. 9 and 10 show perspective views of two different parts of a bracket.
  • Fig. 11 shows a front view of a dispenser composed of the parts according to Figs. 9 and 10 and provided with a cap and pump device according to Figs. 1-8.
  • the pump housing 1 is cast in one piece of rubber with a through-channel 2, in which cavities 3 and 4 are arranged for inlet and outlet valves 5 and 6, respectively, which enclose between them a valve chamber 13.
  • the pump housing is provided with a collar 7 and tapers conically down to an outlet opening 8, the size of which is suitably adapted to the pump medium so that the pump housing does not drip.
  • the inlet and outlet valves 5 and 6, respectively, are made of rubber and have a cylindrical form with a membrane 9 and 10 respectively, at one end.
  • the membrane 9 of the inlet valve 5 has a V-shaped through-slit 11, thus forming a flexible valve tongue 12.
  • the slit 11 is bevelled in relation to the surface of the membrane so that the tongue surface facing the interior of the valve chamber 13 is greater than the opposite surface of the valve tongue.
  • the tongue 12 can thus only be opened in the direction towards the interior of the valve chamber from its normal sealing position.
  • the outlet valve 6 is provided with a normally sealing slit 14 in the membrane 10. When an overpressure is generated in the interior of the valve chamber 13 by pressing the elastic walls of the pump housing radially inward, the valve tongue 12 is pressed into sealing contact while the slit 14 opens when a certain pressure in the interior of the valve chamber has been exceeded.
  • Fig. 6 and 7 show a special button 19 which is designed to fit into and be displaceable across the hole 18 in the cap flange 17.
  • the button consists of a button portion 20 and a central extension 21 therefrom.
  • Fig. 8 shows the cap 15 with the button 19 in place.
  • the button 19 is provided with spring hooks 22, 23, which are snapped into the elongated hole 18 when mounting the button in the cap flange.
  • the button 19 with its extension 21 will be in front of the elastic walls of the valve chamber. Pressing the button 19 will thus press the extension 21 against the pump housing, and since a fixed member is mounted against the opposite side of the pump housing, the pump housing walls will be compressed so as to achieve the intended and previously described pump effect.
  • Fig. 8 with a pump mounted therein according to Fig. 1, is, as was mentioned, designed to be screwed onto a container (not shown here) containing the product for dispensing.
  • Figs. 9 and 10 show an example of a holder designed to carry such a container with associated capsule and pump housing.
  • Fig. 10 shows the actual bracket 24, which is designed to be screwed to a wall, and
  • Fig. 9 shows an associated cover 25.
  • the bracket 24 is arranged with an upwardly open gutter 26.
  • the flange 17 of the cap When the container with the cap 16 with the associated pump device are mounted, the flange 17 of the cap will be in front of the narrow portion 27 of the gutter, so that this portion and the flange 17 will completely, and with a suitably selected fitting, enclose the cylindrical pump device.
  • the composite device described above is shown in Fig. 11.
  • a device of this type can be suitable as a disposable product.
  • the container consists of a compressible bag member
  • the user may be tempted to press the bag to dispense the contents.
  • the contents would then flow out in an uncontrolled manner, but with the special pump construction according to the invention, and especially with the valves in the same, an uncontrolled dispensing is practically impossible.
  • the inlet valve of the pump device if required because of dimensions and materials, can be reinforced with a detachable plastic body, which fits into the cylindrical hole in the same and in order to permit through-flow is provided with a central hole.
  • This plastic body then serves primarily as a support for the inlet valve and prevents it from being deformed when the walls of the pump housing are pressed in. Deformation of the valve could result in pressing the valve into the container.

  1. Vorrichtung, ausgebildet zum Abgeben von flüssigen oder pastösen Produkten aus einem Behälter, mit einem an eine Öffnung des Behälters angeschlossenen Pumpengehäuse (1), welches mit einem Einlaß- und Auslaßventil (5 bzw. 6) versehen ist, weiches Pumpengehäuse (1) aus einem hülsenähnlichen, einstückig aus elastischem Material, vorzugsweise Gummi, hergestellten Abschnitt besteht, und welche Ventile (5, 6) ebenso aus einem elastischen Material, vorzugsweise Gummi, hergestellt sind und eine hülsenähnliche Form mit einer Membran (9) bzw. 10) an einem Ende hat, dadurch gekennzeichnet, daß die Ventile in Hohlräumen (3, 4) befestigt sind, die dafür in der Nähe beider Enden des hülsenähnlichen Pumpengehäuses ausgebildet sind, daß das Auslaßventil (6) einen normalerweise abdichtenden Schlitz (14) in der Membran (10) aufweist, welcher Schlitz sich aufgrund eines Überdrucks in das Pumpengehäuse öffnet, daß zumindest ein im wesentlichen V-förmiger oder halbkreisförmiger Durchgangsschlitz (11) in der Membran (9) des Einlaßventiles angeordnet ist, um eine flexible Zunge (12) zu bilden, welcher Zungenschlitz im Verhältnis zur Ebene der Membran abgeschrägt ist, so daß die Zunge nur aus ihrer normalen dichtenden Lage in Richtung auf das Innere (13) des Pumpengehäuses abbiegbar ist, wodurch ein radiales Zusammendrücken des Pumpengehäuses eine dosierte Menge des Produktes durch das Auslaßventil abgibt und das Pumpengehäuse über das Einlaßventil aufgefüllt wird, wenn das Pumpengehäuse seine normale Form einnimmt.
