Definitions

  • the present invention relates to a metering pump assembly comprising a container sealed to a manually operable pump which, in the unloaded condition, shuts off fluid communication between an outlet communicating outlet of the pump and the interior of the container through at least one check valve. Furthermore, the present invention relates to a method for producing a filled Dosierpumpenan extract and the use of such a Dosierpumpenan expect.
  • From the DE 100 49 898 C2 is a delivery device for fluids known, with which, for example, liquid pharmaceuticals or cosmetics metered out of a container can be applied.
  • the metering pump used for this purpose operates without air compensation, the liquid being accommodated inside the container in an environmentally sealed inner bag which collapses during emptying.
  • valve in the discharge head of this known dispensing device is designed so that this indeed opens when the redesignate product flows under pressure from the pump in the discharge head, but is held by a spring in its closed position, as long as the product is not a sealing body against shifts the spring pressure, no residual air can be sucked through this discharge head to the outside. The extraction of the residual air is therefore only possible if the delivery head has not yet been placed on the pump.
  • this entails the disadvantage that residual air always remains in the discharge head, which must be removed by a user from the discharge head before the first use by actuating the pump before the product can be removed. Since air is compressible and, for example, for the application of drugs with a pump stroke only small amounts of the product, e.g. about 28 mg, are often required this many pump strokes, which is perceived by users as unsatisfactory.
  • Object of the present invention is in contrast to provide a metering pump arrangement of the type mentioned and method for producing a filled Dosierpumpenan Aunt, in which a complete suction of residual air from the container is facilitated.
  • the container is sealed via a lid with a container facing, in particular concave recess relative to the pump, wherein the suction port of the pump for sucking gas in the container by the pump not or not at least protrudes substantially over the lid in the container.
  • the gas in the container can be sucked by the pump, which open during suction by the negative pressure of the suction or the check valve (s) of the pump and thereby establish a fluid connection between the outlet port and the interior of the container.
  • the check valves can be formed either by balls which are pressed, for example by compression springs against corresponding valve seats, or the check valves can also be formed by rubber lips or the like. Elastic elements in their unloaded Condition close a valve seat and, for example, can be lifted by fluid pressure of this.
  • the suction of the residual air from the container can be carried out either in a state of Dosierpumpenanssen in which only the pump with eg. A check valve, but without an application head, which usually has a further check valve is provided on the container or the suction is carried out by the pump and the delivery head, ie through both check valves that open during aspiration.
  • the discharge head or the like can be retrofitted to the pump.
  • the outlet opening can therefore be formed in the sense of the present invention either by a nozzle or the like on the discharge head or by any opening through which the pump can be connected to an application head.
  • the suction port of the pump according to the invention does not or not materially into the container.
  • the residual air remaining in the container after filling of the container accumulates in its upper region formed by the recess, in which the pump is arranged.
  • the suction must be as flush as possible with the inner wall of the container or at most only a few millimeters protrude into the interior of the container.
  • a residual air bubble formed above the liquid can thus be sucked out of the container through the pump by the suction process described above, until the liquid taken up in the container is sucked through the suction opening. Since no air flows back into the container through the at least one check valve, the liquid received in the container can after suction the residual air in any position, ie directed upwards with the pump, upside down or laterally discharged by the pump from the container, the suction of the pump can always suck only liquid.
  • liquid is intended to encompass all flowable substances that can be dispensed with such a pump. These may be viscous, pasty or gelatinous substances in addition to low viscosity.
  • a suction cup When sucking the gas out of the container, a suction cup can be placed on the metering pump arrangement such that at least the outlet opening of the pump is surrounded by the suction cup.
  • the suction cup is placed on the Dosierpumpenan Aunt that the suction cup is mounted on a wall of the container or an optionally associated with this lid and this sealingly surrounds the outside of the container or lid protruding part of the pump. It is then only necessary for sucking the residual air from the container, previously remove a possibly provided protective cap from the pump or the outlet opening.
  • the negative pressure applied in the suction bell the residual air is then sucked out of the container, whereby the two check valves open by the suction pressure.
  • the balls, sealing lips or the like against the elastic closing forces are lifted from its valve seat. After suction, the check valves close automatically, so that a re-entry of air into the container is avoided.
  • the container has a particular flange-like lid, via which the container is sealed against the pump, wherein the suction port of the pump does not protrude or at least not substantially over the lid into the container.
  • the lid can be formed of a stiffer material, so that it can be connected to a, for example. Stiffer enclosure or enclosure of the container with variable volume.
  • the container Since the metering pump arrangement according to the invention operates without air compensation, the container must have a variable volume. This is possible in a particularly simple manner in that the container is formed from a collapsible foil or the like, for example as a foil bag. During the emptying of the container, it therefore contracts or folds up.
  • the container is substantially associated with a rigid shell, which surrounds the container and with the pump, for example, via the lid is connectable.
  • a vent opening is provided in the rigid shell, so that the collapse of the container in the shell is not hindered.
  • the lid is provided with a peripheral edge, to which, for example, the film bag-like container is attached.
  • the peripheral edge may be formed, for example, flange or stepped, wherein the film bag or the like container is preferably attached to the lower in use position edge region of the lid and sealingly applied.
  • the use position is defined as a position in which the pump is located on the vertically upper side of the lid and the container, for example, designed as a foil bag is vertically below the lid and the pump.
  • the rigid shell may be formed as a, at least on one end face open, in particular cylindrical container, said at least one open end side is closed by the lid.
  • the metering pump arrangement Consequently, it is particularly easy to produce by placing the lid with the container attached thereto onto the stiffer shell.
  • a seal may be provided between the stiffer shell and the lid.

  • the depth of the recess of the attachable to the bag designed as a container edge of the lid to the suction port of the pump continuously, in particular curved increase.
  • the configuration of the recess is not limited to a spherical cap-like shape, but the recess may also be conical, frusto-conical, pyramidal, truncated pyramid, stepped and / or designed with curved or straight faces.
  • the recess is designed such that in use position of the preferably defined by the peripheral edge lowest point as possible adjacent to the container and in the use position vertically highest point in the region of the suction port of the pump. This makes it possible that any residual air accumulates in the container close to the suction port of the pump and thus can be easily sucked by the pump.
  • the pump is a pressure chamber with a guided in this piston chamber, a first check valve which connects the pressure chamber to the container, and with a possibly a delivery head associated second check valve.
  • the first check valve allows a flow from the container into the pressure chamber, if there is a lower pressure in this than in the container, while a flow in the opposite direction is basically blocked.
  • the second check valve allows a flow from the pressure chamber into the environment, when the pressure in the pressure chamber exceeds a defined value, while a return flow, for example. Of ambient air in the pressure chamber through the second check valve is not possible.
  • the check valves may be formed as balls, which, for example, are pressed elastically against a valve seat by a spring.
  • the check valves are formed only by a sealing lip, which rests in the unloaded state on a valve seat and can be lifted by fluid pressure elastically from the valve seat.

  • the outlet opening in another way, for example, to deliver individual larger drops of a liquid through the metering pump arrangement.
  • the dosing pump arrangement according to the invention is particularly suitable for dosing, dispensing, application or the like of liquid cosmetics and / or pharmaceuticals.
  • a method for producing a filled metering pump arrangement comprises the following steps: filling a flowable product in a foil pouch, then closing the foil pouch by a manually operable pump which, in the unloaded state, shuts off fluid communication between an outlet port communicating with the environment and the interior of the foil pouch by at least one check valve and at least approximately complete removal of the pouch located in the foil pouch gases.
  • the film bag in particular by means of a punch or the like. Compressed and thereby the gases contained in the foil bag are ejected from this through the pump and / or by a bypass channel bypassing them.
  • the inventive ejection of the residual air by the pump itself or by a bypass channel can be achieved even with pumps or applicator heads, which do not allow extraction of the residual air, a complete venting of the film bag.
  • the dosing pump arrangement is thus ready for operation and it can already be taken with the first pump stroke by a user, the flowable product.
