Definitions
- the invention relates to a valve for the dispensing of Pressurized liquids according to the preamble of the claim 1 (see for example EP-A-0 696 545).
- valves Aerosol dispenser Except for the contents and the container is the valve the most important part of such a pack. From the flawless Operation of the valve at all times and under the usability of the product depends on all circumstances. Also if the package has been stored for a long period of time, the valve the first time the product is operated correctly and in the predetermined manner Submit spray pattern. Otherwise, the whole pack together with content unusable.
- valves usually exist for an aerosol pack of a valve body, a delivery tube and one Ring seal.
- the valve body is fluid-tight at the edge of an in a lid designed for a container opening fixable.
- the dispensing tube is axial in the valve body slidably mounted and from a closed position against the action of an elastic element, in particular a helical compression spring, movable.
- the ring seal is located between the edge of the lid opening and the valve body and tightly encloses the delivery tube.
- the ring seal consists of an elastic sealing material, preferably rubber or the like.
- Inside the discharge tube is a discharge channel formed of a side opening, in particular bore has in the closed position by the ring seal on the outside is closed.
- the side opening or hole comes from the ring seal free, so that a medium under pressure in the container passes through the valve body, the side bore and the discharge channel of the delivery tube can escape to the outside.
- 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 lockable for holding a medium under pressure is.
- the cover 11 has a central opening 12 for receiving a dispensing tube 13, which is inside the container extends into a valve body 15. Between the inside of the valve body 15 and the inside of the container there is a fluid connection via a riser.
- 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 one radially outwardly extending circumferential flange which in assembled state of a radially inwardly extending Ring projection on the cover 11 is gripped such that the valve body 15 is held clamped by the cover 11.
- a flat ring seal 20 is arranged such that it tightly encloses the delivery tube 13.
- the Ring seal 20 consists of an elastic and corrosion-resistant Material.
- the dispensing tube 13 is in the valve body 15 axially displaceably mounted, namely from a in FIG. 3rd shown closed position against the effect of a Helical compression spring.
- valve of the prior art shown in Figure 3 has however, the disadvantage that when the delivery tube 13 is pushed in the elastic ring seal 20 with this dragged inwards can be. As a result, the opening of the Passage 24 released from the ring seal 20 later than expected becomes.
- the dispensing tube 13 must therefore be proportionate deep down or into the inside of the container to the connection from the interior of the container to the discharge channel 25 to create the passage 24. By dragging the seal and through the sharp-edged through opening it can damage the sealing material and also parts of the seal are separated, which affects the function of the valve and its service life is shortened.
- the object of the present invention is to provide a valve for dispensing to provide liquids under pressure, with which the problems mentioned above were largely avoided can be, and with the safely reproducible Dosages are possible.
- the invention relates to a valve according to claim 1 for dispensing pressurized liquids, foams, Gels or the like, with a fluid-tight on the edge of one in one Lid for a container opening designed lid opening attachable Valve body, one axially displaceable in the valve body stored, from a closed position the effect of an elastic element, especially one Coil spring movable delivery tube, and one between the dispensing tube around the edge of the lid opening and the valve body Ring seal made of rubber or the like.
- Elastic sealing material such that this in Closed position of the delivery tube or valve one in the delivery tube trained discharge channel closes fluid-tight, wherein the delivery tube has a ring flange with one of the ring seals facing ring projection for producing a fluid seal between the ring seal and the discharge channel of the dispensing tube comprises, the fluid connection to the discharge channel the delivery tube by one formed in the delivery tube and at the end of the discharge channel inside the container Passage is formed.
- the outer edge of the passage is rounded.
- FIG. 2 shows that a not blunted, essentially sharp-edged opening edge 29 of the passage 24 a pronounced tendency in the opening process of the valve for dragging and squeezing the seal 20.
- Figure 1 is due to the blunted (rounded) shape of the opening edge 29 entraining and squeezing the seal 20 barely noticeable. This will make it work well of the valve and destruction of the sealing material can be avoided.
- the cross section of the blunted edge of the outer opening passage 24 may have any shape that includes a avoids a sharp edge. It can e.g. rounded (preferably bead-like, as shown in Figure 1), beveled or be trumpet-shaped.
- the passage 24 designed according to the invention can e.g. to the manufacture of the delivery tube 13, which is usually made a suitable plastic is formed in a simple manner e.g. using 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 one at the curvature of the bluntness of the outer Matching circle e.g. the radius of a bead-like Rounding is suitably in the range of 1/3 to 1/2 the diameter of the passage 24.
- the outer Opening can be in the area of the ring seal or even partially below that through the top peripheral edge of the ring seal facing ring projection defined level.
