Definitions

  • the invention relates to a valve for aerosol containers with a valve housing which can be fully or partially inserted into the mouth of the aerosol container and which is followed by an extension ⁇ on smaller free cross section for receiving a riser pipe.
  • Valves of this type are generally known and are used in a variety of ways. Although they generally have a high level of operational safety, it occasionally occurs when aerosols are released that a uniform atomizing mist does not form. Instead of a uniform and rapid discharge, a batch-wise discharge can then be observed, in which the atomizing mist flutters and no longer spreads specifically and quickly enough. The valve is exposed to fluctuating pressure loads and begins to knock and can also freeze.
  • Riser tube has an inlet opening into which a tube extending into the interior of the extension, an Eanule or the like is inserted.
  • the gas phase in the aerosol container is given a further function by the invention. While it was previously only effective in such a way that it forced the liquid phase via the riser pipe into the valve chamber and out of the aerosol container, it now additionally acts directly on the outflowing liquid phase via the inlet opening and the tube, whereby the discharge of solvent and Active ingredient supports.
  • the local area of action is chosen so that an optimal effect is achieved. This area lies below the actual valve chamber, where the flow velocity is correspondingly high due to the small flow cross section.
  • the gas phase is not simply reduced in pressure, but is used to increase the flow rate of the outflowing aerosol, the propellant being loaded with solvent and active substance and the flow becoming more uniform and stable.
  • the tube proposed by the invention, the cannula or the like extends into the interior of the extension and thus ensures that the gas phase becomes effective in the desired manner.
  • a valve is particularly effective if the tube or the like extends up to approximately the central axis of the extension.
  • the inside diameter of the tube is related to the inside diameter of the fort set in a size ratio of about 1: 3 to about 1: 7.
  • the tube or the like is aligned radially.
  • the tube or the like expediently closes to the outside approximately flush with the extension.
  • Figure 1 shows an inventive valve in a vertical section
  • Figure 2 shows a valve according to the invention in connection with an aerosol container made of glass in front view.
  • a valve according to the invention has, inter alia, a valve housing 1, a valve body 2 guided therein with an outlet pipe 3 and a closure cap 4.
  • the cap 4 is made of metal and is placed on the valve housing 1 from the outside and pressed against it. It has an edge 5 with which it can be placed over the mouth of an aerosol container and can also be pressed against it.
  • a compression spring 6 is arranged, which strives to always keep the valve body 2 in the closed position.
  • an extension 7 adjoins the valve housing 1, into which a riser pipe 8 is inserted.
  • the extension 7 has a substantially smaller free cross section than the valve housing 1.
  • the extension 7 has an inlet opening 9 above the riser pipe 8, into which a tube 10 is inserted.
  • the tube 10 is aligned radially to the extension 7 and extends approximately in the middle. It has a comparatively small inside diameter, its inside diameter depending on the inside diameter of the riser pipe 8 or the extension 7.
  • a valve according to the invention is connected to an aerosol container 11 made of glass.
  • the cap 4 is placed on the mouth of the aerosol container 11 and pressed by flanging its edge 5.
  • the outlet pipe 3 carries one
  • Atomizer head 12 by means of which it can be operated.
  • the valve housing 11 is completely inserted into the mouth of the aerosol container 11.
  • the inlet opening 9 together with the tube 10 is only perceptible from the outside as a punctiform inlet in the extension 7.
  • the separation of the contents of the aerosol container 11 into a gas phase and a liquid phase is indicated by a dashed line 13.

Abstract

La soupape pour recipient d'aerosol comporte un corps de soupape qui est place dans l'orifice du recipient et auquel est raccorde un appendice dont la section presente un etranglement, destine a recevoir un tuyau ascendant. L'appendice (7) presente, dans le but d'obtenir une meilleure repartition du solvant et de l'additif lors d'une decharge simultanee, rapide et a debit stable, en amont du tuyau ascendant (8) un orifice d'admission (9) dans lequel est place un petit tube (10), par exemple une canule ou analogue qui s'etend jusqu'a l'interieur de l'appendice (7). Le petit tube (10) atteint, de preference, l'axe de l'appendice (7). Le diametre interieur du petit tube (10) sera dans un rapport de 1 : 3 a 1 : 7 avec le diametre interieur de l'appendice (7). Le petit tube (10) est, en particulier, dispose radialement et son extremite exterieure affleure la surface exterieure de l'appendice (7).
