Definitions

  • the invention relates to a pumping device for a container for liquid, pasty or foamable skin cleansing and care preparations, for. B. for liquid soaps, disinfectants, skin protection pastes or cream, according to the preamble of claim 1.
  • the skin cleansing preparations may also contain rubbing.
  • Pumping devices of the type mentioned are well known from the prior art. These pumping devices are also called Suction pumps and in particular also referred to as bellows pumps. They are used for arrangement on a container, wherein the container, for example, receives a liquid soap and in a dispensing device, which may be mounted, for example, on a wall next to a washing station, is used.
  • the pumping means such as a bellows pump
  • the amount of liquid present in the bellows pump is discharged, wherein liquid is then drawn from the container into the bellows chamber formed by the bellows during the return movement of the bellows.
  • a pumping device is for example from the DE 20 2009 006 603.7 U1 known.
  • a container pumping device which is housed in a dispenser housing.
  • the pumping device comprises a laterally projecting projection which is arranged at the outlet end of the bellows and which, as is known per se, is grasped by a so-called "catcher clip".
  • the "catcher clip” of the dispensing device provides upon actuation of a pivotally connected lever for the pumping movement of the bellows.
  • the introduction of the projection of the bellows chamber in the "catcher-clip” takes place against a lateral resistance, since the "catcher-clip” is slightly pushed apart during the insertion process, whereby the bellows laterally evades. Manually it must then be ensured that the projection enters the "catcher bracket".
  • the pumping device according to the WO 2009/103583 A1
  • To form the bellows chamber comprises a cylindrical bellows, wherein laterally to the bellows guide means are provided to ensure that when inserting the container including the pumping device into the dispenser housing, the bellows can not escape laterally.
  • the proposed construction is very expensive and therefore expensive, which in particular due to the fact that the bellows has the lateral guide means in the form of rods, which must be attached to both ends of the bellows.
  • the bellows according to the prior art is designed as a kind of bellows, wherein the folds of the bellows run helically rotated. Such bellows are expensive to manufacture.
  • a pump with a tapered bellows known, the individual bellows elements are formed stepwise conically tapered.
  • the wall thickness of the so step-shaped bellows is the same over the individual stages.
  • a valve device is provided with an inlet and an outlet valve, wherein the two valves are designed as so-called flutter valves.
  • a pump handle acts on the tip of the bellows to compress the bellows.
  • the object underlying the invention is therefore to provide a pumping device of the type mentioned, which is produced by simple and inexpensive injection molds, ie in particular has no undercuts, which also has transversely to the longitudinal axis of increased stability to pivoting of the bellows at To avoid insertion into the dispenser device.
  • each bellows element comprises a rim-shaped base element and an annular wall element connected therewith by an annular film hinge.
  • the bellows which forms a bellows chamber, is tapered due to the adjoining bellows elements of different diameters. Due to the conicity already receives the bellows increased rigidity transverse to the longitudinal axis of the bellows. From the taper of the bellows and the feature that the individual bellows elements are pressed into each other, it follows that the bellows has no undercuts, so that such a bellows using simple tools is inexpensive to produce.
  • the individual bellows elements can be latched together in the compressed state opens up the possibility of compressing the bellows of the pumping device to a length which is approximately the distance from the receptacle for the container to the catcher.
  • Bracket corresponds. This means that, for insertion of the container together with the pumping device, the bellows of the pumping device remains in the depressed or at least partially depressed state at least until the container is inserted into the dispensing device.
  • the bottom element and / or the wall element in cross-section diamond-shaped, square or rectangular are formed.
  • a film hinge in the extended state of the bellows connects the bottom and the wall element over the shortest distance between the floor and wall element.
  • the cross section of the annular bottom element corresponds approximately to the radial distance between two wall elements, ie in particular the cross section is not smaller, but rather larger; This measure also prevents a "snapping over" of the bellows elements of the bellows.
  • each bellows element has a rim-shaped bottom element and an annular wall element connected therewith by an annular film hinge, wherein in particular the width of the coronal bottom element is greater than the sum of the thickness of the coronal bottom element and that of the annular wall element. From this it becomes clear that when the bellows are compressed, the bellows elements of smaller diameter are inserted into the bellows snapping over the larger annular wall element located about the respective film hinge, the individual bellows elements remain in this position until the bellows chamber is pulled apart again.
  • the bellows example can be completely compressed, which in addition to the actual pumping possibly also offers advantages in transport, inasmuch as then the pumping device takes up relatively little space, or it is compressed in the attached state on the container by exactly the amount , which is necessary to the insertion of the container together with the pumping device in the dispensing device in a simple manner as already described.
  • the pumping means comprises an inlet and an outlet valve.
  • the inlet valve is located at the pumping means in the region of the transition to the container, whereas the outlet valve is arranged at the lower, the tapered end of the pumping device or of the bellows.

  • This poppet valve is characterized in detail by a valve body, wherein the valve body by a neck spaced from the valve body receives a valve plate, which bears radially movably on the outlet. From this it is clear that, when the bellows is compressed, the valve disc to the passage of liquid soap, for example, forms a radial distance to the outlet.

  • Inlet and outlet valves work in opposite directions. That is, when the inlet valve is closed upon compression of the bladder, in contrast, the outlet valve is opened because the pressure of the preparation due to the reduction of the volume of the bellows chamber, the valve plate is transferred against the force of the spring element in the open position.
