Definitions

  • Atomizer For dispensing media, especially pharmaceuticals or cosmetic products are numerous types of donors, e.g. Atomizer, has been developed. They mostly work with manual drive for a pump piston that holds the medium under the pressure necessary for discharge. Especially for disposable dispensers are very expensive and precisely dosed pharmaceuticals have been developed in which the container for the Medium is simultaneously the pump chamber and the container closure the pump piston. Such an atomizer is from the DE-A-44 12 041 known.
  • the manual drive is the Media container received in a sleeve on which the User pushes and the pump piston immediately mechanically emotional.
  • the object of the invention is therefore a dispenser for flowable Media, especially for atomizing liquids to create the one with simple construction and easier Usability Prerequisites for an even media discharge creates.
  • This task is carried out by a donor with the characteristics of Claim 1 solved. He can follow the at the same time the media chamber forming the pump chamber is a partially compressible one Have pressure chamber that with a pressure fluid, preferably a liquid, e.g. Water, filled and which also serves as a media chamber lock Pump piston pressurizes.
  • a pressure fluid preferably a liquid, e.g. Water
  • the piston can be at rest have a predetermined inhibition that will be overcome must to set the piston in motion while the running resistance be lower to continue the discharge process can. This can be done by choosing the right material for the piston and media chamber wall as well as the pressure between pistons and media chamber hike happen.
  • certain mechanical inhibitions for example a circumferential rib in the media chamber wall, one Snap device or the like
  • pressure fluid Media In addition to liquids, other fluids that can flow are also used as pressure fluid Media, for example gases, such as air, are suitable, which is not so direct due to its compressibility Enable transmission of forces like liquids, for that but due to this compressibility a pressure accumulator form one after overcoming the static friction of the piston ensures complete and rapid execution of the stroke, thus a pressure point function as previously described.
  • gases such as air
  • the invention makes it possible to operate the dispenser to carry out a hydraulic translation. For that he has Pistons different effective piston surfaces for media and Pressure chamber. With a relatively low pressure in the Pressure chamber can be a correspondingly higher pressure in the Media chamber are generated.
  • the Pressure chamber a manually operated snap device exhibit.
  • arching the wall of the pressure chamber the effect of a "snap frog" can be achieved.
  • This can produce a very short-term sudden Output process can be used.
  • Pressurized fluid as a combination of compressible and incompressible Media to choose, for example, in a A certain volume of gas ("air bubble") is also stored in the liquid becomes. If, for example, a "snap frog effect" a sudden pressure build-up in the pressure chamber is achieved, this can be something under certain circumstances Maintain a longer discharge stroke become.
  • the pressure chamber can be designed in the manner of a squeeze container be and preferably directly to the media chamber be connected.
  • Media chamber can be designed as a somewhat thick-walled cylinder and a thin-walled jacket as a pressure chamber connect, which after filling the media chamber with the medium to be discharged, inserting the piston and filling the Pressure chamber with the pressure fluid e.g. through a weld is closed.
  • the donor can be taken out produce very few parts, namely the media and Pressure chamber forming base part, the piston and possibly a Use in the media chamber with the outlet opening Formation of a spray nozzle interacts.
  • the base part it is advantageous to injection mold the base part to produce, in the injection mold at the same time or different plastics or plastic variants in succession for different areas of the molded body be injected. So the cylinder section from one made of harder, i.e. more rigid plastic, while a softer, more flexible plastic for the pressure chamber section is chosen. Both should advantageously be of the same Type of plastic, only with different hardness settings, in order to enable species-specific disposal. This is because of the lack of other materials, such as Metals or the like, possible with the invention in any case.
  • the discharge opening can be closed by valves which can be either pressure or path operated.
  • valves which can be either pressure or path operated.
  • the discharge opening can simultaneously form a spray nozzle with a snap-off closure to close.
  • Fig. 1 shows a number of several side by side and with each other contiguous donor of the same type 11.
  • Dispensers are disposable dispensers that act as pump atomizers are trained. They each have a housing forming base part 12, which, like all other parts of the Dispensers can be made of plastic injection molding.
  • a deposed cylindrical pump-cylinder unit 13 of the base part 12 forms a media chamber 20 on one side, at its end completed by an end face 14.
  • An outlet opening 15 Located in this in the middle is an outlet opening 15 which forms a nozzle closed by a molded snap-off closure 16 is.
  • This snap-off closure is subsequent to that in the End wall 14 provided outlet opening together with the base part 12 injection molded nozzle, which has a very thin, but tightly closing the outlet opening Wall is molded around the outlet opening.
  • a Handle disc 29 enables the manual opening of the outlet opening by unscrewing this snap lock 16.
  • a spherical insert 17 is in the cylinder section 13 pressed in up to the spherical cap-shaped end wall 14 enough. Together with the wall of the base part, it borders Flow channels 18 from. By running along the front wall Grooves in the front wall become spiral Swirl channels 19 are formed. They stand with the flow channel 18 in connection.
  • the swirl channels 19 give one through the Flow channel flowing liquid has a swirl at the nozzle-shaped outlet opening 15 for a fine atomization in an atomizing cone.
  • the pump cylinder unit 13 is designed in two stages and has a discharge cylinder 46 closer to the outlet opening 15 with a smaller diameter and a subsequent one Drive cylinder 47 with a much larger diameter.
  • the Diameter difference can preferably be 1: 1.5 to 1: 4 amount, which corresponds to the area ratio generated pressure change approximately two to sixteen times can be.
  • a piston 21 is guided, which one in the narrower discharge cylinder 46 inserted piston portion 56, which has a conical shaft section 32 a piston sleeve 57 with the larger diameter connected is.
  • This piston sleeve is sealing against the Inner wall of the pump cylinder section 47.
  • the piston is cup-like hollow, the inner opening of the media chamber points to a complete discharge of the contained therein Medium 24 not to hinder.
  • the piston surface 14 facing the insert is from the adapted for the same reason to the shape of the insert, i.e. spherical cap.
  • the piston 21 can be made of a flexible plastic, possibly rubber-like material and has on the outside some circumferential ribs or sealing lips that make it relative firmly seated and tight in the pump cylinders. He closes the media chamber 20 tightly and ensures that the medium therein, e.g. one pharmaceutical effective liquid, sealed against all external influences is.
  • the volume of the pressure chamber 22 is somewhat larger than the volume to be deployed the media chamber 20.
  • the pressure chamber 22 is straight through one side Welding or sealing seam 30 similar to a tube closure locked.
  • the cylinder and pressure chamber sections 13, 28 injection molded in one piece, but exist through a two-component spraying process made of plastics different properties (cylinder and media chamber: harder; Pressure chamber: softer). The plastics go with it a cohesive connection, so that the base part as is to be described in one piece.
  • Fig. 1 shows in dashed lines that the more rigid plastic also in the pressure chamber section 28 web-like stiffening elements 60 can form from the cylinder unit 13 to close run to the final weld. You are on the provided flatter sides of the elliptical pressure chamber wall and ensure a distribution due to their greater rigidity the pressure applied by two fingers.
  • the in 1 left dispenser shows a window 61 in dash-dot lines the stiffening element 60, which connects it to the Hinge-like cylinder unit made more flexible. This can also achieved through bending points of reduced material thickness become.
  • the also through the two-component spray technology stiffening elements are created by the flexible Wandungsetti23 like a bellows with each other connected.
  • the dispenser 11 projects beyond the dispensers adjacent to it a connecting web 26 in connection, which has a predetermined breaking point is connected to the base part. All basic parts a series of adjacent dispensers 11 made together in one piece in the plastic injection molding process and so remain, if necessary on one opposite Smaller number of dispensers per packaging unit separated up to the consumer.
  • the unit is the side by side Dispenser base parts 12 first with the Insert 17 provided. Then the medium 24 is in the media chamber filled and the piston 21 in the pump cylinder section 13 used.
  • the pressure chamber 22 with the pressure fluid 25 filled Because this, if it's a liquid, none has a different task than the application of a hydraulic one Pressure, it can be any liquid, mostly water for simplicity. According to the conditions However, other liquids or additives can also be used in it, for example for frost protection. Then all pressure chambers are welded on the weld 13 sealed. This creates a Magazine of several donors lying next to each other, everyone for themselves, are completely closed.
  • the consumer can use one of the external ones Separate the magazine's donors by going back and forth Bending the predetermined breaking point 27 destroyed. First removed the user closes the lock so that the outlet opening 15 is released. The outlet nozzle can also by a Tear-off film must be closed. Then he presses with two Fingers on the correspondingly marked printing areas 31 the pressure chamber and thus puts the pressure fluid 25 under Print. This pressure has a significant effect on the lower one in FIG. 1 larger effective drive piston surface 65 of the piston 21 and drives this after overcoming a static friction adhesive effect upwards, whereby the medium 24 in the media chamber 20 a builds up appropriate pressure. The medium can through the Flow channel 18 and the swirl channels 19 to the outlet opening flow and be atomized there. The much smaller one Discharge piston surface 14 of the discharge piston part 56 is generated thereby a correspondingly higher pressure in the media chamber 20th
  • a hole 41 in the area between the cylinders prevents one Compression of trapped air when actuated.
  • the movement of the piston 21 only begins after assembly a sufficient pressure in the pressure chamber and accordingly the media chamber. If the piston friction in the pump cylinder 13 is not sufficient to be sufficient Building up high initial pressure could result in the cylinder wall for example, a lead or a slight circumferential Bead to be present for sufficient inhibition worries. Normally, the friction is enough, which is also much greater than the sliding friction during the pump stroke, by after the start of the piston movement the medium may be a piston lubrication can work.
  • the dispenser consists of only three plastic parts (base part 12, insert 17 and piston 21). You can use plastics of a comparable type and are therefore species-specific work up again. The pressure fluid that will mostly be water can, does not bother.
  • Fig. 1 dispenser shows a side hole 71 in Discharge piston section 56, the piston interior and thus the pressure chamber with the piston outside in one place connects between two sealing lips. If the top one Insert the next sealing lip towards the end of the discharge stroke the channel 18 extending into the media chamber 20 pressure fluid 25, e.g. Air flowing out of the nozzle and thus also take away and discharge the last remnants of the medium. This means full use of the under certain circumstances very expensive medium possible. The user also notices on the decreasing back pressure that the discharge stroke has ended.
  • FIGS. 1 and 2 shows the embodiment 3 the following differences:
  • the pressure chamber section 28 which is attached to the pump cylinder section 13 connects, is in the manner of a tube jacket or a hot water bottle, i.e. he has one on the side circumferential seam or flat spot and in its surfaces are two domed, for example spherical cap Bulges 40.
  • the material is so elastic but still true to form that it reacts "like a frog" i.e. with pressure over a dead center into the opposite Bulge snaps.
  • the pressure chamber section 28 is also filled with the pressure fluid 25.
