Definitions

  • the invention relates to a manually operable metering device for a medium having an applicator housing which has at least one discharge opening for discharging the medium, with a pumping device having a pumping chamber arranged in the applicator housing, and with an elastically flexible membrane which forms a wall section of the pumping chamber and in the applicator housing for changing a chamber volume of the pumping chamber is arranged to be elastically movable, and the outside facing away from the pumping chamber is associated with an actuating surface for a manual pumping movement.
  • Metering devices for a medium are variously known in various designs. Such metering devices have manually operable pumping devices. Each pumping device communicates with a medium reservoir. A flow path between the medium reservoir and the pumping chamber can be closed by an inlet valve. In order to enable a discharge process by the pumping device, the pumping chamber is in operative connection with the discharge opening of the dosing device via an outlet valve. The discharge opening is provided in an applicator housing of the metering device, wherein the discharge opening is used for the metering or application of the medium to the environment. For actuating the pumping device, a manually operable actuator is provided.
  • the pumping device may be designed as a push piston pump or in another manner.
  • the pumping chamber is at least partially formed by an elastic flexible membrane.
  • a compression of the pumping chamber and consequently a discharge takes place in a simple manner by a manual pressure load on the flexible membrane, whereby it is deformed and inevitably reduces a volume of the pumping chamber.
  • the elastic flexibility of the pumping chamber is designed such that after removal of the pressure load an automatic return of the membrane takes place in the unloaded starting position in order to suck the medium to be conveyed into the metering chamber.
  • the object of the invention is to provide a metering device of the type mentioned above, which allows easy removal by manual operation a medium discharge.
  • the applicator housing has a flow path from the pumping chamber to the discharge opening, and that the membrane forms an outlet valve of the pumping chamber.
  • the membrane assumes a multiple function. On the one hand, it forms a wall section of the pumping chamber. On the other hand, it serves as a contact surface for manual operation of the pumping device, and finally it is designed so that they protrudes into the flow path between the pumping chamber and the discharge opening, that it forms the outlet valve of the pumping chamber.
  • a single component namely the elastically flexible membrane, thus several functional sections of the metering device are achieved.
  • the solution according to the invention is suitable for the application of highly viscous or low-viscosity flowable media or liquids, in particular for cosmetic or for pharmaceutical purposes.
  • the applicator housing has a ventilation channel leading to a medium reservoir, and the membrane forms a ventilation valve for the ventilation channel.
  • the metering device is suitable for multiple dosing, because after each dispensing process, the discharged liquid volume can be compensated by air from the environment.
  • the applicator housing is provided with a spray nozzle as a discharge opening.
  • a spray nozzle as a discharge opening.
  • the applicator housing is provided with a discharge opening designed for a highly viscous medium.
  • a discharge opening designed for a highly viscous medium.
  • gels, ointments, creams and the like can be applied hereby.
  • the actuating surface of the membrane is arranged in a recess of the applicator housing and, in the unloaded resting state, is in particular flush with an outer contour aligned with the applicator housing.
  • the actuating surface which is part of the membrane, can either be formed directly as a finger rest, or it serves as a contact surface for an actuating element, which establishes the operative connection between the manual pressure load of an operator and the membrane.
  • the membrane is made of an elastomeric material as a one-piece, bell-shaped designed component.
  • the membrane is integrated in an end region of the applicator housing and aligned at least substantially coaxially with a central longitudinal axis of the applicator housing in the applicator housing.
  • the applicator housing is designed in two parts, and the membrane is clamped coaxially between an inner part and an outer part of the applicator housing.
  • the membrane is radially biased in the assembled position.
  • the recess is preferably provided on an end region of the outer part of the applicator housing, so that the actuating surface of the membrane can be operated from an end face of the outer part.
  • the outer part and the inner part of the applicator are preferably non-positively or positively in the axial direction - related to the central longitudinal axis of the Applikatorgeophuses - connected to each other.
  • the membrane is necessarily mitfixiert in its installed position and preferably radially biased. This achieves a particularly fast valve function.
  • the actuating surface of the membrane is provided on the outside of a clamping region of the membrane in the applicator housing and a lip portion forming the outlet valve within the Einspann Schemees, and the clamping region of the membrane is designed in particular as a solid-body joint.
  • a vent valve for the ventilation path provided in the region of the recess of the Applikatorgeophuses sealing portion of the membrane is provided as a vent valve for the ventilation path, which closes this in the unloaded state of the membrane and releases in manually compressed state of the membrane.
  • the ventilation path is thereby inevitably released with a deformation of the membrane.
  • the membrane is designed so that both the outlet valve for the pumping chamber and the venting valve for venting the medium storage are opened at a corresponding deformation of the membrane at the same time.
  • the membrane is made in one piece from an elastomeric material and has a bellows region on which at least one circumferential or helical groove is formed.
  • the bellows-shaped configuration of the membrane allows a particularly favorable ratio between a volume enclosed in the resting state of the membrane and a volume still enclosed by the membrane at the end of the discharge process. That is, in such a configuration of the membrane, a larger volume of medium can be promoted, so that the thus equipped discharge device can be used for a wider range of applications.
  • a particularly advantageous deformation behavior of the membrane is achieved by the at least one circumferential or helical groove, since the membrane is deformed at least substantially only in the bellows-shaped region.
  • the bellows region can be formed in particular by an axial arrangement of at least two oppositely oriented and integrally connected cone-shaped rings. As a result, at least one circumferential groove is formed and the bellows has a substantially V- or U-shaped cross-section of preferably constant thickness or a multiple repetition of such a cross section.
  • the bellows region can also have a helical, ie helical thread-like geometry, wherein in particular multi-start constructions, as are known from the field of multi-start screw threads, can be used for the bellows region. This ensures a particularly favorable flexibility of the membrane and flexible materials with different characteristics can be used.
  • the membrane in a preferably annular transition region between the bellows region and a lip portion forming the outlet valve at least one, at least partially circumferential groove for a movement decoupling between bellows and exhaust valve. Due to the at least partially circumferential groove, which can be mounted in particular in those sectors of the transition region, which are coupled to the lip sections acting as exhaust valves, it is achieved that upon actuation of the membrane and thereby caused deformation of the bellows region no or only one weak influence on the lip portion occurs. Thus, the lip portion unaffected by the deformation of the bellows portion can fulfill its function as an outlet valve.
  • At least two lip portions are provided on the membrane, which have different geometries.
  • the geometries of the lip sections may differ in particular with regard to the wall thickness of the lip sections and / or the length of the lip sections. This provides the opportunity to realize in a single membrane at least two different valve characteristics for the metering device.
  • one of the at least two lip sections can be inserted into the metering device in such a way that the outlet valve is formed by this lip section.
  • This outlet valve is suitable, for example, when using a slightly longer lip portion for the dosage of highly viscous media such as gels and has a soft valve opening characteristic.
  • a shorter valve lip causes a harder valve characteristic, as it is preferably used for the dosage of low-viscosity, for example, aqueous media.
  • At least one sealing element for separating an annular gap section provided for the medium guide to a medium-free annular gap section is provided on the applicator housing. This ensures a reliable separation of the medium from the environment, in particular it can be ensured that the medium does not enter the ventilation duct.

  • a user For an actuation of the metering devices 1 c and 1 d, of which reference is made below by way of example only to the embodiment according to FIG. 9, a user must exert an operating force on the actuating surface 12 c. By the actuating force, the medium enclosed in the pumping chamber 7c is pressurized. Upon reaching a sufficient pressure level of the lip portion 13c is deflected from the rest position shown in Fig. 9 in an open position, so that the medium along the flow path 17c and the lip portion 13c over into the discharge port 18c and from there into the environment can flow. As a result of the outflow of the medium, the volume enclosed in the pumping chamber 7c is reduced and an elastic deformation of the membrane 6c takes place.

  • the sealing collar 24c has also moved away from the inner end face of the closure part 4c and thus opens the passage 16c to the medium store (not shown).
  • the membrane 6c Since the membrane 6c is designed in the manner of a multi-turn coil spring, it has a tendency to deform back to the initial position shown in FIG. 9 back. The back deformation results in a negative pressure in the pumping chamber 7c.
  • the negative pressure causes an opening of the inlet valve 8c and thus a subsequent flow of medium from the medium storage, not shown, since the lip portion 13c seals the flow path 17c and thus prevents an inflow of ambient air into the pumping chamber 7c.
  • ambient air can flow into the medium container through the opened passage 16c and ensure pressure equalization there.
  • two sealing ribs 27c are provided on the applicator housing 5c, which extend in the axial direction on the conical outer surface of the applicator housing 5c and are continued from there onto the flat, annular region of the applicator housing 5c.

  • the sealing ribs 27c seal the membrane from the front side. This prevents ingress of medium before, during and after the discharge process into the annular gap section, which is arranged adjacent to the ventilation channel.
  • the sealing ribs locally widen the lip sections formed as a conically encircling skirt in such a way that an interference fit occurs between the applicator housing 5 c and the membrane, as a result of which the desired sealing effect is achieved. This can be prevented that medium accumulates in the ventilation duct and possibly leads to contamination of the ambient air flowing into the medium reservoir.
  • An encoding surface 28c is provided on the applicator housing 5c, which is provided for a correct installation of the applicator housing 5c in the closure part 4c, so that an incorrect installation is almost impossible.
  • the use of the applicator housing 5c described in FIG. 11 is not limited to the embodiment of FIG. 9, but can be used for all the metering devices described above.
