Definitions

  • the invention relates to a media dispenser with a storage container, a sliding piston which can be displaced therein and which seals the storage space at one end and a piston pump which is provided on the opposite end of the container and which is connected on the outlet side to a media discharge opening, and a sliding pump piston receiving pump cylinder is connected on the input side to the storage room.
  • Known media dispensers of this type are generally used for pasty active ingredients, for example toothpaste.
  • the known dispensers are not suitable for media which are to be atomized, for example low-viscosity media, such as medical therapeutic and prophylactic agents or the like, and in particular for the discharge of precisely metered small amounts. They are also relatively difficult to operate and the discharge pressure is usually low.
  • the invention has for its object to provide a media dispenser of the type mentioned, which ensures a very precise and precisely repeatable dosage of the amount of media discharged with a simple structure and still allows higher discharge pressures, so that the dispenser can also be used for such media, that are to be atomized during discharge.
  • a media dispenser of the type described at the outset in accordance with the invention in that the pump piston towards the end of the return stroke in the manner of a slot control has a connection opening between the storage space, which can be changed in volume, to maintain full filling with the media supply quantity, and is sealed in a vacuum-tight manner releases the pump chamber and if the part of the pump chamber lying between the pump end position of the pump piston and the connection opening is provided as a metering chamber, the connection opening of which is immersed in this vacuum-tight storage chamber at least in its release position.
  • connection opening is preferably formed by the open end of the pump cylinder, through which the pump piston is completely moved out of the pump cylinder towards the end of the return stroke and that in particular has a funnel-shaped inlet surface for the pump piston.
  • this design ensures that the lowest possible flow resistances occur when the medium is sucked into the pump chamber, the size of the connection opening corresponding to the inner cross section of the pump cylinder, which accommodates a sudden suction of the medium after the connection opening has been released; due to the funnel-shaped inlet surface, the flow resistances that occur are further reduced.
  • connection opening is expediently closed on part of the return stroke of the pre-suction piston and / or the piston sealing surface of the pre-suction piston is free Provided end of the intermediate cylinder.
  • a vacuum is built up before the connection opening to the medium is released, in addition to being in the pump chamber also in the intermediate cylinder, that is to say double-acting, and the intermediate cylinder is filled in such a way that the medium is in close contact with the still closed connection opening.
  • the connection opening is released in the further course of the return stroke when the maximum negative pressure in the pumping chamber is reached, the medium so pre-sucked is sucked into the pumping chamber in such a way that its dosing chamber is certainly completely filled.
  • a structurally simple embodiment is achieved if the pump piston is arranged in a fixed position relative to the intermediate cylinder, in particular approximately coaxially in the intermediate cylinder, and preferably at least one outlet opening to the storage space is provided between the outer periphery of the pump piston and the inner periphery of the intermediate cylinder.
  • the overall cross-section of this overflow opening is expediently larger than that of the connecting opening in order to achieve favorable flow conditions.
  • the design according to the invention also makes it possible to provide an arrangement in a simple manner in which the metered discharge amount can be changed in a precisely defined manner if necessary.
  • This can be achieved in a simple manner, for example, by the volume of the metering chamber being made variable, the end wall of the pump cylinder opposite the pump piston, for example with an outlet sleeve guided in an adjusting thread of the cylinder wall of the pump cylinder, being axially adjustable and guided, for example, by self-locking is.
  • the pump stroke of the thrust piston pump is limited by the pump piston striking the opposite end wall of the pump cylinder.
  • the pump piston and the pump cylinder are spring-loaded against one another in the starting position and are limited in the starting position, preferably the pump cylinder being movably mounted with a handle, for example a container cap that holds a return spring and covers the pump is.
  • a return spring can also be designed as a resilient element which is in one piece with at least one of the two components which can be moved relative to one another and in particular can be formed by bulging guide arms of the handle which are subjected to buckling.
  • the pump piston forms a with the V b rrats integrally united and positionally fixed with respect to this unit, while the cylinder and optionally the presuction representing during the pump stroke in the hand moving parts, resulting in a structurally very simple embodiment of the dispenser is obtained.
  • an outlet valve is designed as a non-return valve, which preferably has an outlet nipple provided on the circumference with at least one outlet opening and, as a valve closing part, a valve stocking elastically surrounding the outlet nipple, the free end of which, for example, forms the outlet opening. This also ensures that the outlet valve closes very quickly and tightly at the end of the media discharge or at the beginning of the return stroke and maintains this vacuum-tight seal safely until the metering space is filled again or until the next pumping stroke.
  • the design of the dispenser is further simplified if all essential parts of the dispenser are arranged in a common axis and are expediently axially symmetrical; this applies in particular to the pump cylinder, the storage space, the outlet opening, the intermediate cylinder, the handle and the drag piston.
  • the cross section of the dispenser can be round, in particular circular, polygonal or different.
  • the piston pump is arranged projecting into the storage space and preferably has a suction part which is approximately axially aligned with the pump piston as the end section projecting furthest into the storage space.
  • the medium from the pump cylinder is taken deep from the storage room, so that the medium inside half of the storage space only has to perform very small internal flow movements.
  • the suction port is overhung in the storage room.
  • the outlet valve is provided so that the pump cylinder is particularly securely sealed to the outside when the dispenser is not in use, that is to say when the pump piston is unloaded.
  • the valve closing pressure of the outlet valve is higher than the maximum pressure in the storage space, so that under no circumstances can active ingredient escape from the dispenser unintentionally, that is to say without actuating the pump.
  • trailing piston is cup-shaped to the piston pump open hollow and that the inner cross sections of the trailing piston are essentially exactly adapted to the, in particular stepped tapered, outer shape of the portion of the piston pump protruding into the reservoir, such that this section fills the cavity of the trailing piston when the storage space is empty.
  • the design of the dispenser according to the invention enables a very precise metering of the amount of media discharged per piston stroke even if this amount is very small, for example on the order of a few hundredths of a cubic centimeter.
  • a media dispenser according to the invention has a storage container 2, which is designed, for example, as a standing vessel, and a storage cap arranged thereon at the same time as a closure cap Thrust piston pump 1, which is provided, for example, at the upper end opposite the standing surface of the storage container 2.
  • the cylinder 3 is in turn formed at its free end as a pre-suction piston 5 which is guided in an intermediate cylinder 6 surrounding the pump piston 4 at a distance.
  • This intermediate cylinder 6 forms the neck of the storage container 2 provided at the associated end, both the inner cross sections of the intermediate cylinder 6 and that of the cylinder 3 being smaller than those of the storage container 2.
  • the intermediate cylinder 6 extends as far as the associated end wall 7 of the continuously cylindrical storage container 2, for example, and its free end projects further than the pump piston 4 located in it, which is thus provided entirely within the intermediate cylinder 6.
  • the pumping piston 4 is arranged on a piston-shaped piston shaft 8, as seen in its axial direction, as a result of which four transfer openings 9 are formed between the interior of the storage container 2 and the cylinder space 10 of the intermediate cylinder 6, which lie approximately in the plane of the end wall 7.
  • the pre-suction piston 5 can be moved approximately to the free end of the intermediate cylinder 6 so that the pump piston 4 approximately on the last third of the Return stroke has completely moved out of the open end of the cylinder 3, such that its front opening facing the pump piston 4 forms a connecting opening 11 which is open to the cylinder chamber 10 and can be closed by the pump piston 4 in the manner of a slot control.
  • This connection opening 11 is essentially delimited by the narrower end of a funnel or truncated cone-shaped inlet surface 12 for the pump piston 4, which narrower end directly connects to the piston raceway 13 of the cylinder 3 and whose further end is larger than the piston cross-section;
  • the inlet surface 12 has a taper angle of approximately 90 °.
  • cylindrical piston race 13 limits that part of the pump chamber of the push piston pump 1 which is provided as a metering chamber 15, since the pump piston 4 at least approximately abuts the annular shoulder-shaped end face 14 of the piston running surface 13 at the end of the pump stroke.
  • the cylinder 3 is structurally or integrally united with an outlet nipple 16 which, with the interposition of an outlet valve 17 designed as a check valve, connects the metering chamber 15 to an outlet opening 18 for the active substance.
  • This line connection 19 is relatively short and essentially rectilinear, wherein it decreases in cross-section to the check valve 17 and is expanded again between the check valve 17 and the outlet opening 18.
  • An exemplary embodiment is the line connection 19 through a first section which is axially identical to the metering chamber 15 with a reduced cross-section compared to the metering chamber 15, an adjoining section with a further reduced cross-section and also lying in the axis of the metering chamber 15 and two or more radially opening into it Outlet openings are formed in the outlet nipple 16, these outlet openings 20 simultaneously forming the valve openings of the outlet valve 17.
  • the outlet valve 17 has an elastic valve stocking which surrounds the entire length of the outlet nipple 16 and is secured against axial displacement, and which surrounds the outlet nipple -16 in the region of the outlet openings 20 lying on its circumference in an elastically tight manner and over the end of the valve Exhaust nipple 16 protrudes in such a way that its end directly forms the outlet opening 18, the opening cross section of which is thus essentially equal to the largest cross section of the outlet nipple 16.
  • the cylinder 3 and the outlet nipple 16 are provided on the end wall 23 of a handle 27, which is perpendicular to the central axis of the dispenser, and are formed integrally therewith.
  • This handle 22 has a plurality of guide arms 24, in the exemplary embodiment shown four, evenly distributed over the circumference and parallel to the dispenser 8, which surround the storage container 2 at a small distance on the circumference and are provided with inwardly directed cams 25 at their ends, to which, as the stop 26 limiting the return stroke, an annular collar projecting beyond the outer circumference of the storage container 2 is assigned.
  • a helical compression spring is provided as a return spring 27, which is supported on the one hand on the inside of the end wall 23 and on the other hand on the stop 26 and surrounds the reservoir 2 on the circumference over part of its length.
  • a helical compression spring is provided as a return spring 27, which is supported on the one hand on the inside of the end wall 23 and on the other hand on the stop 26 and surrounds the reservoir 2 on the circumference over part of its length.
  • the trailing piston 29 is freely movable along its cylinder track with relatively little friction, the storage container 2 being open on the side of the piston 29 facing away from the storage space 28 or being provided with a pressure compensation opening, so that on this side the Piston 29 no negative pressure can arise.
  • the storage space 28 including the cylinder space 10, the metering space 15 and the line connection 19 is completely filled with the medium to be metered out and the cylinder 3 is under the force of the return spring 27 at the end of its return stroke. If the cylinder 3 is now moved against the force of the return spring 27 in the direction of the pump piston 4, part of the amount of media in the cylinder chamber 10 is first displaced in the direction of the storage chamber 28 until the pump piston 4 along the inlet surface 12 Has reached the beginning of the piston track 13 of the metering chamber 15 and has thereby closed it; the closing voltage of the exhaust valve 17 is chosen so large that it does not open until this moment. Therefore, the climbing piston is pushed back in this phase and, if it.
  • the quantity of media in the metering chamber 15 is pressurized by the pump piston 4, whereby the outlet valve 17 according to FIG. 2 opens, so that the metered amount of media exits via the line connection 19 at the outlet opening 18.
  • the total stroke is, for example, only 5 mm and the storage container 2 of the dispenser shown enlarged in FIGS. 1 to 5 holds, for example, only about four cubic centimeters.
  • the outlet valve 17 closes by itself again due to the elastic tension of the valve closing part 21. If the handle 22 is now released, the cylinder 3 according to FIG. 3 moves towards its starting position under the force of the return spring 27 moved back. Here, the pre-suction piston 5 moves back in the intermediate cylinder 5, as is the case for the pump piston 4 and the cylinder 3. Due to the negative pressure occurring in the intermediate cylinder 6, medium is sucked into the intermediate cylinder 6 from the storage space 28. As soon as the pump piston 4 has reached the start of the inlet surface 12 during this return stroke, the connection opening 11 is suddenly released during the further return stroke movement, the maximum possible negative pressure being reached at this moment by the return stroke movement of the pump piston 4 in the metering chamber 15.
  • connection opening 11 As soon as the connection opening 11 is opened, it is therefore in the intermediate cylinder 6 medium sucked in suddenly and completely filled into the dosing chamber 15.
  • the cylinder space 10 thus belongs to the storage space 28, in which the connection opening 11 is completely immersed during the return stroke.
  • the climbing piston 29 is trailed by the underpressure which arises in the storage space 28 by a distance corresponding to the metered quantity, such that the storage space 28 decreases in volume but always remains completely filled.
  • the thrust piston pump 1-a is designed to be removable from the storage container 2a such that it can be refilled with active substance through its container neck.
  • the pump piston 4a and the intermediate cylinder 6a are structurally combined with a screw sleeve 7a, which can be detachably screwed onto an external thread of the container neck 31 and forms a vacuum-tight seal.
  • the handle 22a is in this case directly limited in terms of its return stroke with respect to the screw sleeve 7a.
  • the outlet nipple is formed in the embodiment according to FIG. 6 by an outlet sleeve 16a which is provided with an external thread with which it is adjustable in the direction of the pump stroke in an adjusting thread 30 provided in the cylinder wall 13a of the pump cylinder 3a and can be locked by self-locking.
  • This outlet With its inner end, the sleeve 16a forms the end wall 14a of the metering chamber 15a opposite the pump piston 4a, so that the size of the metering chamber 15a and thus the amount of media to be metered out can be changed by adjusting the outlet sleeve 16a.
  • the media dispenser according to the invention is particularly suitable, for example, for the metered delivery of active substances for inhalation devices or as a drip dispenser, which can be designed for an exact number of liquid drops to be dispensed per pump stroke. However, it can also be used for other media than drugs.
  • the piston pump can also be form-fitting. be fastened to the container in such a way that it lies at a distance from the inner circumference of the neck and projects relatively deep into the storage space 28 with a suction part or suction nozzle, for example forming an inner tapered end.
  • the trailing piston can then have an outer piston ring with two annular, sealed lips provided at both ends and a fitting sleeve located therein, which with its open end facing the piston pump merges in one piece and tightly into the piston ring.
  • the associated end face of the trailing piston 29 then bears almost completely over the inside of the end wall 7 of the container 2.
  • the storage space 28 can thereby be completely emptied except for the tiniest remains of medium.
  • the atomization or the discharge can also be carried out in any position of the dispenser, for example in the top position, since medium is always present on the suction part.
