Definitions

  • the present invention relates to a metering pump arrangement having a container that is connected, in sealed manner, with a pump that can be manually activated.
  • the pump blocks off a fluid connection between an outlet opening of the pump that stands in connection with the surroundings, and the interior of the container, by means of at least one kick-back valve, in the unstressed state.
  • the present invention relates to a method for the production of a filled metering pump arrangement, as well as to the use of such a metering pump arrangement.
  • a dispensing device for fluids is known from DE 100 49 898 C2, with which liquid pharmaceuticals or cosmetics, for example, can be dispensed from a container in metered manner.
  • the metering pump used for this purpose works without air equalization, whereby the fluid is accommodated within the container within an inner bag that is sealed relative to the surroundings, which bag collapses as it empties.
  • a similar metering pump is proposed in DE 101 08 486 A1, in the case of which a passage for the residual air to be drawn off is formed between the outer wall of the piston and the inner wall of the pressure cylinder of the metering pump.
  • This passage stands in connection with the inner bag, on the one hand, by way of an opening provided on the pump housing, and with the surroundings, on the other hand, by way of a valve-like flap within the pump. Any residual air remaining in the inner bag after it has been filled can be drawn off through this channel within the pump, in order to avoid the disadvantages mentioned above.
  • forming this channel for the residual air in the inner bag presumes great precision in the production of the pump.
  • the production of this known dispensing device is made more expensive by the complicated structure of the pump.
  • the metering pump projects into the inner bag with its pressure cylinder and its intake opening that is assigned to the kick-back valve on the inner bag side.
  • the valve in the dispensing head of this known dispensing device is configured so that it opens when the product to be dispensed flows out of the pump into the dispensing head under pressure but is held in its closed position by means of a spring as long as the product does not displace a sealing body counter to the spring pressure.
  • no residual air can be drawn towards the outside via this dispensing head. Drawing off the residual air is consequently possible only when the dispensing head has not yet been set onto the pump.
  • this feature has the disadvantage that residual air always remains in the dispensing head, and this air must be removed from the dispensing head by a user, before first-time use, by means of activating the pump, before the product can be dispensed. Because air is compressible, and only small amounts of the product, for example approximately 28 mg, are dispensed with one pump stroke for the application of medications, for example, many pump strokes are often required for this application, which users consider unsatisfactory.
  • the intake opening of the pump for drawing off gas situated in the container through the pump does not or at least does not significantly project beyond the lid into the container.
  • the gas situated in the container can be drawn off through the pump, whereby while it is drawn off, the kick-back valve(s) of the pump open(s) by means of the partial vacuum of the intake device, and therefore produce(s) a fluid connection between the outlet opening and the interior of the container.
  • the kick-back valves can be formed either by balls that are pressed against corresponding valve seats, for example, by means of pressure springs, or also by rubber lips or similar elastic elements, which close off a valve seat in the unstressed state, and can be lifted off from it by means of fluid pressure, for example.
  • Drawing off the residual air from the container can take place in a state of the pump in which only the pump, with one kick-back valve, for example, but without a dispensing head, which usually has another kick-back valve, is provided on the container.
  • drawing off the air takes place through the pump and the dispensing head, i.e. through both kick-back valves, which are opened during the drawing-off process.
  • the dispensing head or the like can be affixed to the pump subsequently.
  • the outlet opening can therefore be formed either by a nozzle or the like on the dispensing head, or by any desired opening by means of which the pump can be connected with a dispensing head.
  • the intake opening of the pump does not or does not significantly project into the container, according to the invention.
  • the intake opening In order to avoid having the pump project all the way into the fluid with its intake opening, which is desirable for dispensing the fluid in pump operation, but is unsuitable for drawing the residual air out of the container, the intake opening must end as flush as possible with the inner wall of the container, or project at most only a few millimeters into the interior of the container.
  • a residual air bubble formed above the fluid can thus be drawn off from the container, through the pump, by means of the drawing-off process described above, until the fluid accommodated in the container is drawn in through the intake opening. Because no air flows back into the container through the at least one kick-back valve, the fluid accommodated in the container can be dispensed from the container in any desired position after the residual air has been drawn off, i.e. with the pump oriented at the top, standing on its head, or lying on its side, by means of the pump. As a result, the intake opening of the pump can always draw in nothing but fluid.
  • fluid used with regard to the present invention is intended to include any and all substances capable of flow, which can be dispensed using such a pump. These substances can be not only low-viscosity substances but also substances that are highly viscous, paste-like, or gel-like.
  • a suction bell can be set onto the metering pump arrangement so that at least the outlet opening of the pump is surrounded by the suction bell.
  • the suction bell is set onto the metering pump arrangement so that the suction bell is set onto one wall of the container, or onto a lid connected with the container, if applicable.
  • the suction bell surrounds the part of the pump that projects outward beyond the container or the lid, forming a seal. All that is then required to draw off the residual air from the container is to first remove a protective cap that might be provided from the pump or the outlet opening.
  • the container has a lid, particularly a flange-like lid, by way of which the container is sealed relative to the pump, whereby the intake opening of the pump does not project or at least does not project significantly beyond the lid, into the container.
  • the lid can be formed from a more rigid material, so that it can be connected with a sheath or enclosure of the container, having a changeable volume, which is also more rigid, for example.
  • the container must have a changeable volume.
  • a changeable volume is made possible, in a particularly simple manner, by forming the container from a collapsible film or the like, for example as a film bag. While the container is being emptied, this bag consequently draws or folds together.
  • a rigid sheath is essentially assigned to the container. This sheath surrounds the container and can be connected with the pump, for example by way of the lid. In this connection, an air removal opening must be provided in the rigid sheath, so that collapsing of the container in the sheath is not hindered.
  • the lid is provided with a circumferential edge, to which the container in the form of a film bag, for example, is attached.
  • the circumferential edge can be configured in flange-like or stepped manner, whereby the film bag or similar container is preferably attached to the lower edge region of the lid, in the position of use, or rests against it, forming a seal there.
  • the position of use is defined as a position in which the pump is situated on the vertically upper side of the lid, and the container, configured as a film bag, for example, is situated vertically below the lid and the pump.
  • the rigid sheath can be formed as a container that is open at least on one face, particularly a cylindrical container. This at least one open face can be closed off by means of the lid. Consequently, the metering pump arrangement can be produced, in particularly simple manner, by setting the lid with the container attached to it onto the more rigid sheath. If necessary, a seal can be provided between the more rigid sheath and the container.
  • the concave recess in the lid extends in the manner of a dome cap, for example, proceeding from a circumferential edge connected with the container, to the intake opening.
  • the depth of the recess can increase continuously, from the edge of the lid that can be laid against the container configured as a film bag, to the intake opening of the pump, particularly in domed manner.
  • the shape of the recess is not restricted to a dome cap shape; instead, the recess can also have the shape of a cone, a truncated cone, a pyramid, a truncated pyramid, in steps, and/or with curved or straight partial surfaces.
  • the recess is configured so that in the position of use, the lowest point, preferably defined by the circumferential edge, is situated resting against the container, if possible, and the vertically highest point, in the position of use, is situated in the region of the intake opening of the pump. In this way, it is possible that any residual air in the container collects close to the intake opening of the pump, and therefore can easily be drawn off through the pump.
  • the pump has a pressure chamber having a piston guided in this piston chamber, a first kick-back valve, which connects the pressure chamber with the container, and a second kick-back valve that is assigned to a dispensing head, if applicable.
  • the first kick-back valve permits a flow out of the container into the pressure chamber, if a lower pressure prevails there than in the container, while any flow in the opposite direction is fundamentally blocked.
  • the second kick-back valve permits a flow out of the pressure chamber into the surroundings, if the pressure in the pressure chamber exceeds a defined value, while a return flow, for example from the surroundings into the pressure chamber, through the second kick-back valve, is not possible.
  • the kick-back valves can be configured as balls that are elastically pressed against a valve seat by means of a spring, for example.
  • the kick-back valves are formed merely by means of a sealing lip that lies on a valve seat in the unstressed state, and can be lifted elastically off the valve seat by means of fluid pressure.
  • any and all kick-back valves that prevent return flow of air or the like into the container and allow dispensing of the fluid from the container when the pressure in the container or in the pressure chamber, respectively, is greater than in the pressure chamber or in the surroundings, respectively, can be used for the metering pump arrangement according to the invention.
  • the second kick-back valve can be provided in a dispensing head that can be removed from the pressure chamber or piston chamber, if necessary. Drawing off the residual air can take place with or without the dispensing head, because only one kick-back valve is required for this function.
  • the outlet opening can be formed, for example, by means of a nozzle for atomizing the liquid content of the container.
  • the outlet opening in another manner, for example to dispense individual, larger drops of a fluid by means of the metering pump arrangement.
  • the metering pump arrangement according to the invention is particularly suitable for metering, dispensing, applying, or the like, liquid cosmetics and/or pharmaceuticals.
  • a method for the production of a filled metering pump arrangement includes the following steps: filling a product capable of flow into a film bag, subsequently closing the film bag by means of a pump that can be activated manually, which blocks a fluid connection between an outlet opening and the interior of the film bag, in the unstressed state, by means of at least one kick-back valve, and removing the gases situated in the film bag, at least approximately completely.
  • the film bag is compressed, particularly by means of a punch or the like, and thereby, the gases situated in the film bag are ejected from the latter through the pump and/or through a bypass channel that circumvents it.
  • the metering pump arrangement is therefore ready for operation and the product capable of flow can already be dispensed with the first pump stroke by a user. In this way, the ease of operation of the metering pump arrangement is significantly increased.
  • the removal of the residual air from the film bag, according to the invention can be achieved in a particularly easy and fast manner.
  • the kick-back valves can be formed either by balls that are pressed against corresponding valve seats, for example by means of pressure springs, or also by rubber lips or similar elastic elements, which close a valve seat off in the unstressed state and can be lifted off from it by means of fluid pressure, for example.
  • the film bag is brought into a position in which the pump is disposed essentially vertically above the film bag.
  • emptying the residual air from the film bag for example a collapsible film bag, is simplified if the residual air from an air bubble that faces the pump can escape through an outlet opening that is provided in the pump, for example at its vertically lower end.
  • the intake opening for ejecting the gases situated in the film bag is provided on the pump in such a manner that the intake opening does not project or does not significantly project into the film bag.
  • the film bag is introduced into a more rigid container, in comparison with the film bag, before or after it is filled, which container is closed off by the pump, with the film bag.
  • at least one opening remains in the container, through which a punch or the like can be introduced into the container, so that the film bag is compressed in the container, and in this way, the gases situated in the film bag are ejected from the bag through the pump and/or through a bypass channel that surrounds the pump.
  • the film bag and/or the container are closed off by means of a lid, which is connected with the pump.
  • the structure of the metering pump arrangement is particularly compact and simple.
  • At least one kick-back valve of the pump can open and thereby produce a fluid connection between the outlet opening and the interior of the film bag.
  • the balls, sealing lips or the like are lifted off their valve seat, counter to the elastic closing forces.
  • the kick-back valves close automatically, so that renewed penetration of air into the container is prevented.
  • the ejection of residual air from the container can take place in a state of the metering pump arrangement in which only the pump with one kick-back valve, for example, but without a dispensing head, which usually has another kick-back valve, is provided on the container.
  • the ejection takes place through the pump and the dispensing head, i.e. through the two kick-back valves, which are opened in this connection.
  • the dispensing head or the like can be subsequently affixed to the pump. Consequently, in the sense of the present invention, the outlet opening can be formed either by a nozzle or the like on the dispensing head, or by any desired opening by means of which the pump can be connected with the dispensing head.

  • Piston 5 has a central passage opening 9 , through which a fluid can be pumped out of film bag 2 into the surroundings.
  • the first kick-back valve 6 is set in such a manner that this kick-back valve 6 permits flow out of film bag 2 into pressure chamber 4 if the ball-shaped valve element or body 6 a is lifted off its valve seat 6 c by means of a partial vacuum in pressure chamber 4 , counter to the force of the valve spring 6 b . In the opposite direction, however, flow out of pressure chamber 4 into film bag 2 is blocked by means of first kick-back valve 6 .
  • the second kick-back valve 7 is disposed in such a manner that when there is excess pressure in pressure chamber 4 , fluid can escape into the surroundings through kick-back valve 7 , in that the valve body 7 a is lifted from its valve seat 7 c counter to the force of the valve spring 7 b . In contrast, flow of ambient air, for example, back into pressure chamber 4 , is prevented by kick-back valve 7 .
