Definitions

  • the invention relates to a discharge device for media, in particular for media, the solvents or constituents of which are partially or totally volatile to highly volatile, for example tend to evaporate, dry out or the like.
  • Discharge devices according to the invention can expediently have a mechanism for discharge actuation which, in the case of flowable, for example liquid and / or powdery media, can be a pump, a media store of a storage unit or the like charged by a propellant or the like.
  • the media store can thus, like a pump, directly form the pressure or pumping chamber, which can be refilled or not refilled by suction or the like, so that it contains, for example, the entire supply of a medium of the discharge device and possibly with a single one Actuation process can be emptied.
  • the discharge device can enclose the pressure chamber or the storage unit or can be provided for subsequent attachment thereto be so that it forms only one discharge head with a media inlet and a media outlet.
  • hermetic seals for pressure higher than atmospheric pressure e.g. Closure membranes to be pierced or torn, valves to be opened by the discharge pressure of the medium, closure pins to be inserted into the media outlet, or the like.
  • Such closures can either be closed again by an inherent restoring force or can only be transferred from the closed position into the open position, in which they are then secured by a holding force, without a transfer back to the closed position would be possible without interference with the discharge device.
  • the invention is also based on the object of providing a discharge device for media, by means of which disadvantages of known designs or of the type described can be avoided or effects of the type mentioned can be achieved, in particular without the need to actuate a discharge operation in a clear manner Closure should be possible or recognizable from the outside in which position the closure is.
  • the closure can be connected at least on the input side to a passage cross-section which is substantially smaller than the largest internal cross-section of the media store, the pressure chamber or the pump chamber lying transversely to the discharge direction, the closure expediently without the introduction or carrying out a discharge process via an opening force that is mechanically or not transmitted by a fluid is to be transferred from the closing position into the opening position and / or vice versa.
  • the closure can be opened or closed again at any time essentially independently of any other actuation of the discharge device, without the medium having to be exposed to a possibly damaging opening pressure and without the closure closing again automatically when the media pressure decreases.
  • the infinitely adjustable closure can thus be locked in any of its positions and can be transferred from any of these positions to any other position, whereby one, two or more positions are expediently secured by a positive stop, resilient detent which can be overcome in one or two opposite directions, or the like are.
  • the stop positions can be, for example, a fully closed position and a fully open position with the widest passage cross section.
  • a display indicating the respective position and recognizable with a view of the discharge device from the outside for example a marking, or a handle acting as a display element for actuating the closure can also be provided.
  • a friction and / or positive locking can be provided, which enables the discharge process to be actuated only when the closure is partially or fully open.
  • the closure is provided within an outlet channel adjoining the media store in the longitudinal direction, the greatest width of which is less than half or a third of the cross-sectional width of the media store, so that the capillary channel-like narrowness of the outlet channel already results in a closure-like effect is given so that even with downward and am at the lower end of the outlet channel lying outlet a leakage of the medium would not be possible.
  • the width of the outlet channel can be less than 3, 2 or 1/2 mm, which also applies to the passage cross sections of the closure. Even with the closure open, leakage without delivery pressure is therefore not possible.
  • the media storage device is expediently arranged in such a way that a vacuum would be generated in it when its volume was increased with the closure closed or by emptying it from the media outlet.
  • the closure can form the only valve of the discharge device, so that no inlet and / or outlet valves are additionally required.
  • the closure can be formed in a simple manner by two shaft parts which are approximately the same in their outer width and adjoin one another in the longitudinal direction, one of which carries a slider which can be changed in position in the media store or supports the media store in a displaceable manner, while the other directly to the inner end of a nozzle end channel adjacent, which is bounded in one piece from this inner end to its outer end forming the media outlet. From the media outlet, the medium to be discharged is completely detached from the discharge device to the outside in the form of an atomizing cone, a drop, a foam strand, a powder mist, a spray jet or the like.
  • the design according to the invention is particularly suitable for so-called disposable dispensers, from which the entire storage supply of medium is discharged with a single discharge stroke or several discharge strokes connecting in the same direction without intermediate return strokes, after which the discharge device is used up and only for the recovery of its materials or for exchange of the media store is suitable against a filled new media store.
  • the discharge device expediently has a cup-shaped housing which is open at its full face on its end face facing away from the discharge opening or is closed on this end face with an oppositely open cup-shaped housing part, while the other end face is closed with an end wall or a handle for the discharge actuation forms.
  • On this front side is a much narrower than the bowl housing, e.g. essentially axially or rotationally symmetrical discharge head, in which the closure lies and which is penetrated by the media outlet on its outermost end face.
  • the discharge head, the media storage device or the like can be movable relative to the housing to actuate the closure.
  • the discharge device 1 has a one-part or multi-part base body 2 with a housing 3 of the greatest width and an axially immediately following discharge head 4 of the smallest width, which together determine the entire axial extent of the discharge device 1.
  • a thrust piston pump 5 and a one-piece media reservoir 6 made of glass or a material with similar properties, particularly suitable for sterile maintenance, are located within the housing 3.
  • the elongated, cylindrical jacket 7 of the media store 6 merges at one extreme end in one piece into a bottom 8 which is closed in a pressure-free manner and forms a container opening 9 at the end remote therefrom which is at least as wide as the continuously cylindrical inner circumference of the jacket 7. All the arrangements and components mentioned lie in the central axis 10 of the discharge device 1 and are to this essentially axially or rotationally symmetrical.
  • the inner circumference of the media reservoir 6 serves the piston 11 of the pump 5 as a cylinder track, for the displaceable and pressure-tight engagement of which the piston 11 has one or more annularly projecting piston lips 12, which are formed in one piece with the piston 11.
  • the space between the free end face of the piston 11 and the base 8 serves as a pump chamber and as a pre-filled and pressure-tight, sterile and storage space for the medium which is closed against evaporation.
  • a piston shaft 13 Connected to the other end of the piston 11 is a piston shaft 13 which is substantially longer, elongated and does not exceed the width of the memory 6, which extends from the interior of the housing 3 to approximately the free end of the discharge head 4 and opposite it is secured axially rigid.
  • the shaft 13 is penetrated from the storage space to the end of the discharge head 4 by a substantially straight-line outlet channel 14, which connects to the storage space with a media inlet 15 and opens out into the free environment at the other end in a media outlet 16.
  • the base body 2 has a supporting member 17 for the piston skirt, which is formed in one piece with the housing 3 and protrudes freely inside the housing opposite to the head 4 and surrounds the sleeve shaft in a sleeve-like manner over its entire length and approximately in the starting position in the memory 6 protrudes first piston lip 12 to center the memory 6 against tilting movements.

  • a valve-like closure 20 is provided for the outlet channel 14, which is formed by two closure parts 21, 22 which can be rotated by hand about the axis 10.
  • the closure part 21 is formed in one piece with a shaft part or channel piece 23 of the shaft 13, which penetrates the support sleeve 17 in a positionally fixed and rotationally secure manner by a press fit, and is formed in one piece with the piston 11 or from the closure part 21 to the free end face of the piston 11 and with the support sleeve 17 forms the only associated longitudinal section of the shaft 13.
  • the closure part 22 is partially formed in one piece with a shaft part 24 which directly adjoins the shaft part 23 and extends approximately to the free end of the head 4 or the channel 14.
  • the shaft part 24 has a support part 26 formed in one piece with the head 4 for a channel piece or a core body 25, on the outer circumference of which the support sleeve 26 fits tightly over the entire length with a press fit, so that the core body 25 is axially and rotationally secured to the head 4 is connected.
  • the elongated core body 25 is shorter than the shaft part 23 and has approximately the same width compared to this.
  • the elongated part 26 protrudes freely against the end wall of the outer cap 18 and ends at a short distance therefrom, so that it also tightly surrounds the associated end of the shaft part 23 on the outer circumference, but rotatably.
  • the closure parts 21, 22 of the closure 20 lie completely within the associated end of the support sleeve 26, however, the components 23, 25 can also be referred to as closure parts.
  • the supporting part is located as an inner sleeve 26 with a radial spacing within an outer casing 27 which is conically enlarged to the housing 3 and which forms the outermost, exposed outer circumference of the head 4, no components engaging in the annular space between the casings 26, 27.
  • the shaft part 23 is penetrated in the manner of a bore by a single channel section 28 lying in the axis 10, the furthest end of which forms the media inlet 15 and which emerges again at the end face of the closure part 21 with its narrowest width .
  • the channel section 28 can be slightly tapered in the flow direction without gradation and has an average width of approximately 1 mm.
  • the shaft part 24 is penetrated by a channel section 29 of the channel 15 which adjoins the channel section 28 via the closure 20 and which passes over the entire length of the core body 25 as a longitudinal channel radially offset with respect to the axis 10 with an approximately constant width and a smaller width than the channel section 28 and can be formed by a longitudinal groove on the outer circumference of the core body 25 or on the inner circumference of the sleeve 26, so that it is limited in cross section by both elements 25, 26.
  • the core body 25, like the shaft part 23, is rod-shaped, but is designed as a filler lying completely inside the sleeve 26, the end of which belongs to the media outlet 16 forms part of a flow control 30, by means of which the media flow shortly before leaving the media outlet 16 a desired flow influence, for example one Turbulence, a swirl rotation around the starting axis, an impact atomization or the like.

  • the cylindrical outer circumference of the closure part 21 is pressure-tight over the entire length of the cylindrical inner circumference of the opening 37, so that the end of the channel section 28 emerging at the end face 36 is sealed by a type of labyrinth seal.
  • This is supplemented by an end portion 38 of the sleeve projecting over the shoulders 35 26, which surrounds the outer circumference of the shaft part 23 in a tight-fitting manner approximately up to the outer cap 18 and forms an outer rotary bearing 39 for connecting the two shaft parts 23, 24.
  • the channel section 29 extends to the associated end face 35 of the filler piece 25.
  • the outer width of the shaft part 23 can also be slightly larger than that of the filler piece 25 according to FIG. 2, so that the shoulder 35 also axially on an inner shoulder of the sleeve 26 and as opposed to the End face of the filler 25 can be rotatably supported.
  • the jacket of the sleeve-shaped closure part 21 is penetrated by a passage 33 which passes as a longitudinal slot to the end surface 36, but is at a distance from the transition surface 35. Accordingly, the jacket of the sleeve-shaped closure member 22 is penetrated by a longitudinal slot or passage 34 which passes through to the associated end surface 35, but is at a distance from the bottom surface 36, so that the two closure member passages 33, 34 each other only over part of their overlap the respective axial extent and, in the case of congruent alignment, jointly delimit a media passage closed over the circumference, the passage cross section of which is smaller than that of each of the openings 33, 34.

  • These handles 40 can be formed by two projections or gripping surfaces that are approximately plane-parallel and tangential to the outer circumference.
  • the counter-handle 41 for securing the above-mentioned components against the rotational movement is formed by the outer circumference of the housing 3 or by its housing cap 19, which is elongated in the axial view transversely to the axis 10, preferably elliptically flat oval, so that two on both sides of the axis 10 approximately radially protruding, designed as a hollow body handle arms are formed as the radially outermost limit of the discharge device 1.
  • two separate handles 43, 44 are provided, which are formed on the one hand by the housing 3 and, on the other hand, completely recessed therein by the outside of the bottom of the assembly containing the media store 6.

  • the media filling of the reservoir 6 is expediently provided such that the channel section 28 and the passage 33 are completely and bubble-free filled with liquid or the like in order to completely exclude inclusions of air or other gases.
  • the outlet opening of the passage 33 is sealed off from the inner circumference and from the inner end face of the closure part 22.
  • the memory 6 or the handle 43 lies completely and at a distance from the open end within the jacket 45.

  • the handle 40 can also be provided on the media store 6, so that it is rotated relative to the base body 2 or its two components 3, 4 in order to actuate the closure 20.
  • the memory 6 then takes the piston 11 and the shaft part 23, the closure part 21 frictionally in the direction of rotation relative to the housing-fixed closure part 22 and the rest of the base body 2, whereby the closure is actuated. With the closure 20 open, the pumping stroke movement described is then carried out, so that the medium passes through the outlet channel 14 and the medium outlet Overpressure is pushed out.

  • the upstream end of the channel section 29 directly adjoins the end face 36 of the closure part 21 radially outside the channel section 28, so that it is only in line with the passage 33 in line with the channel section 28, but in all other positions through the end face of the Closure part 21 is closed close to the channel section 28.
  • the end face 36 of the filler 25 therefore does not require a recess 37.
  • the accumulator lying with its jacket between the respective handle 40 and the outer circumference of the shaft part 23 or the piston 11 can strike the fastening legs of the handles 40 with its open end in the pump end position.

  • the locking cam lock is overcome in that the handle 40 deflects radially outward under bending deflection of its fastening leg and allows the counterpart, for example the outer collar of the memory 6, to snap past, after which the memory 6 at the end of one strikes another partial stroke on the next cam 52 in a corresponding manner.
  • the closure parts 21, 23 and 22, 25 are first inserted into the support sleeve from the open end of the housing 3 and the head 4, after which the media storage 6, possibly already in the state preassembled with the housing 49 in the same direction on the piston 11 and the support sleeve is attached at least a third of its length.
  • the memory 6 can already be filled, in which case the closure 20 is expediently opened for venting through the media outlet 16 and is only closed when the medium has filled the channel section 28 at least partially or up to the passage 33.
  • the assembly in the embodiment according to FIG. 4 is similar.
  • the shaft part 23 is inserted into the support sleeve 17 in the manner described until its end containing the closure part 21 protrudes freely from the housing 3 or the outer cap 18.
  • the filled memory 6 can then be plugged on as described and the filling of the channel section 28 is visible at the outlet of the medium at the exposed passage 33, because the closure part 22 or the head 4 has not yet been installed.
  • this is plugged in with the components 22, 25 in the opposite direction until it snaps into the bearing 47, in which case the closure parts 21, 22 can already be brought into axial engagement with one another in their mutual locking alignment, so that the closure 20 opens for ventilation and a subsequent closing of the closure 20 as in the embodiments according to FIGS. 1 and 4 is not required.
