Definitions

  • the invention relates to an atomizer for a medium to be atomized, in particular for liquids, for use in the pharmaceutical, cosmetic or medical field, consisting of a cylindrical storage container for the medium to be atomized and an atomizing device connected to this storage container.
  • Such propellant-free atomizers are used for a wide variety of applications and are initially filled with the liquid to be atomized.
  • a suction hose is attached to the atomization device, which projects far into the storage container. So that a largely complete emptying is made possible, the suction hose extends to the bottom of the storage container.
  • dispensers are e.g. known for toothpaste, in which the storage container is closed by an axially movable piston, which is drawn according to the volume withdrawn during each removal process.
  • these dispensers are only suitable for dispensing pasty masses and cannot be used for liquids, since liquids would leak and there is also the possibility that ambient air can penetrate.
  • the invention is therefore based on the object of providing an atomizer which can be used in any position of use regardless of the degree of filling and in which the penetration of ambient air and thus contamination of the medium in the atomizer is reliably prevented.
  • a connection can temporarily be established between the metering chamber and the interior of the reservoir, that the interior of the reservoir is completely filled with the medium to be atomized and that the piston element is tilt-proof and low-friction and airtight on the inner wall of the reservoir is.
  • An atomizer designed in this way has the particular advantage that it is functional in any position of use.
  • the piston element ensures that when the liquid is withdrawn from the interior of the storage container, the piston element is simultaneously tightened, so that the hermetic seal from the environment is retained and no outside air is sucked in.
  • At least one sealing lip is provided between the inner wall of the storage container and the piston element.
  • the piston element has at least two supporting edges which surround the piston element at an axial distance from one another and which are supported on the inner wall of the storage container. This reliably prevents the piston from tilting and thus becoming leaky as it moves along the inside of the storage container.
  • a further development of the invention is characterized in that at least one of the support edges is designed as a sealing lip.
  • the support edge facing the interior of the storage container is provided with the sealing lip, which extends in the direction of the interior of the storage container.
  • the side of the piston element which delimits the interior of the storage container is profiled in such a way that the intake port in the upper end position of the piston element is completely immersed in the liquid supply when it is used up.
  • the intake manifold can also be designed as a piston travel limiter for the piston element.
  • the storage container is essentially depressurized during atomization and during the refilling of the dosing chamber from the storage container.
  • the storage container is preferably made of a plastic, the inner wall of the storage container being particularly smooth in order to keep the static and sliding friction occurring between the piston element and the inner wall to a minimum.
  • the storage container can also be made from a plastic with a particularly slippery surface. This also achieves the necessary tightness.
  • an atomizer for a medium to be atomized, in particular liquids, for use in the pharmaceutical, cosmetic or medical field consisting of a storage container for the medium to be atomized and an atomizing device attached to the storage container that the storage container is connected to the ambient air via a ventilation opening, that a tube-like plastic bag, rubber bag or the like is arranged within the storage container, which with the atomizing device, the interior of the plastic bag with respect to the environment hermetically sealing the air, that the atomizing device is provided with a metering chamber, a connection between the metering chamber and the interior of the plastic bag being able to be temporarily established via a valve device within the atomizing device and an intake fitting extending into the interior of the storage container for the purpose of removing liquid, and that the interior of the plastic bag is completely filled with the medium to be atomized.
  • An atomizer designed in this way also has the particular advantage that it is functional in any position of use.
  • hermetic sealing from the environment is maintained when liquid is removed from the interior of the storage container. An unwanted leakage of liquid is safely prevented here.
  • An embodiment of this variant of the invention is characterized in that the interior of the plastic bag is essentially depressurized. The plastic bag will contract completely when the liquid is removed until it is completely empty.
  • Figure 1 is a schematic sectional view of the atomizer according to the invention with maximum filling of the interior.
  • Figure 2 shows the atomizer of Figure 1 in the deflated condition.
  • Fig. 3 is a partially sectioned three-dimensional representation of the atomizer according to the invention.
  • the atomizing device 1 is provided with a storage container 2, which is firmly connected to it, so that a hermetic seal against the ambient air tion is achieved.
  • the storage container 2 is cylindrical and is closed at its end opposite the atomization device 1 by a piston element 4 which can be moved freely in the axial direction, the interior of the storage container 2 being completely filled with the medium to be atomized.
  • the atomization device 1 contains a conventional metering chamber, with the purpose of removing liquid via a valve device within the atomization device
  • a connection between the metering chamber and the interior of the storage container 2 can be temporarily established. After the predetermined amount of liquid has been sucked in, this can then be dispensed in a metered manner in the next step via a spray nozzle 7.
  • the piston element 4 is loosely guided within the storage container 2, this is pulled further upward in the direction of the intake port 3 each time liquid is removed. The prerequisite for this is that the liquid column in the storage container does not tear off, which would be the case if outside air would penetrate into the interior.
  • the piston element 4 is guided on the inner wall of the storage container 1 in a tilt-proof and low-friction and airtight manner, the inner wall of the storage container 2 being particularly smooth. It is thereby achieved that the reservoir 2 remains essentially depressurized during atomization and during the refilling of the dosing chamber from the reservoir 2. It is also possible to manufacture the storage container 2 from a plastic with a particularly slippery surface.
  • the tilt protection is achieved in that the piston element 4 is provided with at least two supporting edges 5, 6 which surround the piston element 4 at an axial distance from one another and which are located on the inner wall of the storage container
  • a particularly safe guidance of the piston element 4 can also can be achieved if additional support edges are provided on the piston element 4, which are aligned in the axial direction of the storage container 2.

  • the support edge 5 facing the interior of the storage container 2 is provided with the sealing lip. Since it is desirable to empty the storage container 2 as completely as possible, the side of the piston element 4 delimiting the interior of the storage container 2 is profiled in this way, or is provided with a central recess 8. There is thus the possibility that the piston element 4 can move up to the upper end of the storage container 2 until there is almost no more liquid in it. Through the recess 8, the intake manifold 3 can be fully immersed in the upper end position of the piston element 4 when the liquid supply is used up.

  • a plastic bag, rubber bag or the like is arranged inside the storage container 2.
  • This plastic bag is connected to the atomizing device 1, hermetically sealing the interior of the plastic bag from the ambient air.
  • the application and handling of this variant of the atomizer otherwise corresponds to the version with piston element 4.
  • a complete emptying of the plastic bag can be achieved, the plastic bag being increasingly compressed as a result of the external air pressure, in accordance with the amount removed.

Abstract

L'invention concerne un pulvérisateur destiné à un agent, notamment à des liquides et destiné à être utilisé dans le domaine pharmaceutique, cosmétique ou médical. Ce pulvérisateur comprend un réservoir de stockage cylindrique destiné à l'agent à pulvériser et un dispositif de pulvérisation relié à ce réservoir de stockage. Le dispositif de pulvérisation (1) est fixé au réservoir de stockage (2) en fermant ce dernier de façon hermétique vis-à-vis de l'air ambiant. De plus, le réservoir de stockage (2) est fermé au niveau de son extrémité opposée au dispositif de pulvérisation (1) par un élément piston (4) librement mobile dans le sens axial. Aux fins de prélèvement du liquide, une liaison peut être créée par intermittence entre la chambre de dosage et l'intérieur du réservoir de stockage (2) par un dispositif à valve placé à l'intérieur du dispositif de pulvérisation (1) et un raccord d'aspiration (3) débouchant dans le réservoir (2). Le réservoir (2) est entièrement rempli de l'agent à pulvériser et l'élément piston (4) est guidé de façon stable et avec peu de frottement sur la paroi interne du réservoir (1). Le pulvérisateur peut ainsi être utilisé dans n'importe quelle position d'utilisation.
