Definitions

  • the invention relates to a valve for dispensing pressurized liquids according to the preamble of claim 1.
  • valves in an aerosol package In addition to the contents and the container, the valve is the most important part of such a pack.
  • the usability of the product depends on the perfect functioning of the valve at all times and under all circumstances. Even if the package has been stored for a long time, the valve must deliver the product correctly and in the specified spray pattern when it is operated for the first time. Otherwise the entire package and its contents are unusable.
  • valves for an aerosol package usually consist of a valve body, a delivery tube and an annular seal.
  • the valve body can be fastened in a fluid-tight manner on the edge of a lid opening formed in a lid for a container opening.
  • the dispensing tube is axially displaceably mounted in the valve body and can be moved out of a closed position against the action of an elastic element, in particular a helical compression spring.
  • the ring seal is located between the edge of the lid opening and the valve body and tightly encloses the dispensing tube.
  • the ring seal consists of an elastic sealing material, preferably rubber or the like.
  • Inside the discharge tube is a discharge channel formed, which has a lateral opening, in particular bore, which is closed on the outside in the closed position by the ring seal.
  • the lateral opening or bore is released from the ring seal, so that a medium under pressure in the container through the valve body, the lateral bore and the discharge channel of the dispensing tube through to the outside can escape.
  • FIG. 3 shows a valve according to the prior art in longitudinal section.
  • the valve is mounted on a cover 11, with which a corresponding opening of a container, not shown, for receiving a medium under pressure can be closed.
  • the lid 11 has a central opening 12 for receiving a dispensing tube 13 which extends into a valve body 15 on the inside of the container.
  • the valve body 15 is fixed to the edge 16 of the lid opening 12 in a fluid-tight manner.
  • the valve body 15 has a radially outwardly extending circumferential flange which, in the assembled state, is engaged behind by a radially inwardly extending annular projection on the cover 11 in such a way that the valve body 15 is held in a clamped manner by the cover 11.
  • a flat ring seal 20 is arranged in such a way that it closely surrounds the dispensing tube 13.
  • the ring seal 20 consists of an elastic and corrosion-resistant material.
  • the dispensing tube 13 is axially displaceably mounted in the valve body 15, specifically from a closed position shown in FIG. 3 against the action of a helical compression spring.
  • an outwardly open and internally closed discharge channel 25 extends in the direction parallel to the longitudinal center axis.
  • a passage 24 extending transversely thereto connects the discharge channel 25 to the outside of the dispensing tube at a height which is in the closed position at the level of the ring seal 20.
  • the ring seal 20 thus closes the outer opening of the passage 24 in the closed position.
  • An axial displacement of the dispensing tube 13 into the interior of the container clears the outer opening of the passage 24 from the ring seal 20.
  • a fluid connection is thus established between the interior of the valve body 15 and the discharge channel 25.
  • the valve of the prior art shown in FIG. 3 has the disadvantage, however, that when the delivery tube 13 is pressed in, the elastic ring seal 20 can be dragged inward with it. The result of this is that the opening of the passage 24 is released by the ring seal 20 later than expected.
  • the dispensing tube 13 must therefore be pressed relatively deep down or into the interior of the container in order to establish the connection from the interior of the container to the discharge channel 25 via the passage 24.
  • the dragging of the seal and the through-opening formed with sharp edges on the outside can damage the sealing material and also separate parts of the seal, as a result of which the function of the valve is impaired and its operating time is shortened.
  • German patent application P 198 26 308.2 (filing date: June 12, 1998) by the same applicant is intended to solve the above-mentioned disadvantages of the prior art in that the passage opening into the discharge channel is directed from the outside inwards to the inside of the container An oblique bore is formed, the outer opening of which lies at least partially below the plane defined by the upper peripheral edge of the ring projection facing the seal. As a result, the outer end of the passage is at least not completely closed by the ring seal.
  • the fluid connection between the discharge channel and the container is established as soon as the ring flange of the sealing ring is only slightly takes off. This happens abruptly when the dispensing tube is only slightly pressed in.
  • An expedient embodiment of P 198 26 308.2 does provide that the outer opening of the oblique bore lies below the plane defined by the upper peripheral edge of the ring projection facing the ring seal.
  • this embodiment requires precise processing and fitting of the valve into the lid of the aerosol container; in addition, because the outer opening of the passage is always open, the ring projection must be exactly sealed with the ring seal, and a slight and unintentional axial displacement of the delivery tube can already lead to an unwanted delivery.
  • the object of the present invention is to provide a valve for dispensing pressurized liquids with which the problems mentioned above can be largely avoided and with which doses which are easily reproducible are possible in a safe manner.
  • the invention relates to a valve according to claim 1 for dispensing pressurized liquids, foams, gels or the like, with a fluid-tight valve body which can be fastened on the edge of a lid opening formed in a lid for a container opening, and a valve body which is axially displaceably mounted in the valve body.
  • ring seal made of rubber or the like comprises an annular flange with an annular projection facing the annular seal for producing a fluid seal between the annular seal and the discharge channel of the dispensing tube, the fluid connection to the discharge channel of the dispensing tube being formed by a passage formed in the dispensing tube and opening into this at the end of the discharge channel inside the container.
  • the outer edge of the passage is blunt, in particular rounded.
  • Figure 1 is an enlarged view of the encircled area of Figure 3 with a passage designed according to the invention with the valve closed ( Figure la) and with the valve opening ( Figure lb).
  • Figure 2 is an enlarged view of the encircled area of Figure 3 with a passage according to the prior art with the valve closed (Figure 2a), and with the valve opening (Figure 2b); and the
  • Figure 3 shows a valve according to the prior art and according to the preamble of claim 1 in longitudinal section
  • FIG. 2 shows that there is a pronounced tendency for the seal 20 to be carried along and squeezed by a non-blunted, essentially sharp-edged opening edge 29 of the passage 24 during the opening process of the valve.
  • the cross-section of the truncated edge of the outer opening of the passage 24 can have any shape that avoids a sharp-edged edge. It can e.g. rounded (preferably bead-like, as shown in Figure 1), beveled or trumpet-shaped.
  • the passage 24 designed according to the invention can e.g. after the production of the delivery tube 13, which usually consists of a suitable plastic, can be formed in a simple manner, e.g. by means of a heated needle, a drill, or similar suitable tools.
  • the passages generally have a diameter of 0.25 to 1.0 mm, preferably 0.27 to 0.5 mm, and a length of 1.0 to 4.0 mm.
  • the radius of a circle adapted to the curvature of the truncation of the outer edge is expediently in the range from 1/3 to 1/2 of the diameter of the passage 24.
  • the passage can be designed as a transverse bore (parallel to the cross-sectional plane of the ring seal) or as an oblique bore (which extends from the outside inwards and from top to bottom), and the outer Opening can be located in the area of the ring seal or also partially below the plane defined by the upper peripheral edge of the ring projection facing the ring seal.

Abstract

L'invention concerne une valve pour la distribution de fluides, mousses, gels ou similaires, sous pression. Cette valve comprend un corps (15) pouvant être fixé, de manière étanche au fluide, sur le bord d'une ouverture pratiquée dans un couvercle destiné à une ouverture du contenant. Elle comprend également un tube de distribution (13) monté de façon mobile dans le sens axial, pouvant quitter une position de fermeture, en agissant à l'encontre de la force d'un élément élastique, notamment d'un ressort de pression hélicoïdal (21). Elle comprend enfin un élément d'étanchéité annulaire (20) constitué de caoutchouc ou d'un matériau d'étanchéité élastique similaire, placé entre le bord de l'ouverture de couvercle et le corps (15), de façon à enserrer le tube de distribution (13), de telle sorte que l'élément d'étanchéité annulaire obture de manière étanche au fluide un canal d'évacuation (25) ménagé dans le tube de distribution (13), lorsque ce dernier est en position de fermeture. Ledit tube de distribution (13) présente un bord annulaire (27) comportant une partie saillante (28) orientée vers l'élément d'étanchéité annulaire (20) pour produire une étanchéité au fluide entre l'élément d'étanchéité annulaire (20) et le canal d'évacuation (25) du tube de distribution (13). La communication fluidique vers le canal d'évacuation (25) du tube de distribution (13) est assurée par un passage (24) formé dans le tube de distribution (13) et débouchant dans ledit canal d'évacuation (25) au niveau d'une extrémité de dernier (25), située à l'intérieur du contenant.
