Definitions

  • the invention relates to a self-closing valve for dispensing an in particular liquid or pasty product, with a valve membrane, the valve membrane being convex in shape, viewed from the product side, at least in the dispensing area.
  • a self-closing valve of this type results from WO95 / 26306. It is implemented as an injection molded part and incorporated into the front zone of a container closure. The periphery of the arched valve membrane is one
  • a stationary support element is then located on the product side.
  • the valve membrane rests on it.
  • the latter has a hole-like dispensing opening in the center, in which a pin of the support element engages in a tightly closing manner.
  • a hold-down is located on the top of this dispensing area, realized on a hinged lid of the container closure.
  • German patent application 100 63522 describes a self-closing valve, the valve membrane of which is punched out of a flat flat structure.
  • the plate body which is provided with a slot at the same time, is assigned to a support under clamping tension in the manner of an eardrum.
  • the invention has set itself the task of structurally simple and functionally reliable design of a self-closing valve.
  • valve membrane has a retaining ring formed by injection molding around the edge.
  • the mounting ring looks like a hoop. This secures the convex shape of the valve diaphragm resulting from a flat surface. It can be worked extremely thin-walled. Nevertheless, the body is perfectly manageable and can even be stored in a magazine. The shrinkage effect that occurs under cooling favors the dome-shaped throwing up of the valve membrane.
  • valve membrane have an output slot, with slot walls of the output slot opening like a gap on the product side.
  • the outside tensile fiber promotes the corresponding gaping.
  • diaphragm walls lie against each other in the gap bottom, here favored by the compression fiber.
  • the whole thing is presented in such a way that the convex shape goes hand in hand with the internal stresses impressed on the valve membrane.
  • a uniform dome-like dome results in the periphery, since the valve membrane is convex all the way to the edge area.
  • the mounting ring represents the protuberance-neutral zone.
  • the protuberance corresponding to the output can be varied by modifying the ring width to obtain different actuation forces in the output area.
  • the retaining ring is expediently U-shaped in cross section for completely enclosing an outer edge of the valve membrane. This leads to a rotationally symmetrical shoe.
  • a mechanical connection of the mounting ring and valve membrane that goes beyond the form-fitting enclosure can be carried out in such a way that mounting pins extend from the mounting ring. that go through the valve membrane. Pass-through parts can be easily realized using a cross recess, for example.
  • the U-legs of the mounting ring are of different lengths.
  • One form of use is that the U-leg of the retaining ring facing away from the product is longer than the U-leg facing the product.
  • the invention determines the protuberance.
  • the retaining ring have a snap-in shape for snap-fitting the valve into a dispensing container. It is a front assembly.
  • the detent formation is in the most stabilizing and positionally most favorable area if the detent formation is designed to be associated with the U-web.
  • the valve membrane be made of silicone. Depending on the structural requirements, it may also be appropriate for the valve membrane to be made of TPE. If there are corresponding specifications, there is also the possibility of securing the valve-forming parts to each other without the need for the support pin to pass through, by producing the valve membrane with the support ring in a two-component spraying process.
  • valve membrane consists of a plastic film.
  • plastic film has multiple layers.
  • the multi-layer structure results in a variability in hardness, resilience, adjustment to product properties etc.
  • care is taken to ensure that the product cannot enter the joints between the layers.
  • An embodiment of even independent importance is that on the product side the valve membrane is underpinned by a plate part in its dispensing area. The latter acts as a baffle. For example, in the event of a shock load due to installation and even when used as a headrest container, the product cannot penetrate through the dispensing slot.
  • the plate part acts rather as a deflector.
  • the valve membrane lifts off from the plate part under normal load, so that the product can be dispensed in a controlled manner.
  • the construction can be carried out in such a way that the plate part is formed from the same material as the mounting ring. With regard to the valve membrane, this preferably takes place with material reaching through in the sense of the above-mentioned mounting pins.
  • An advantageous embodiment results from the fact that the plate part is resiliently connected relative to the valve membrane. In combination with the plate part there is a kind of pressure catch spring. It is further provided that the connection of the plate part to the mounting ring is formed radially outside the discharge slot of the valve membrane. This can also be used to equalize the pressure.
  • the procedure is such that the dispensing slot extends in a diameter extension beyond the overlap area to the plate part.
  • the plate part on its surface facing the valve membrane is designed to be curved to match the convex shape of the valve membrane. This creates the same flow conditions both for the product and with regard to the opposite air balance. It is then provided that the mounting ring, apart from connecting spring arms, has a plan that deviates from the circular shape of the plate part. Accordingly, an optional cross-sectional shape can be used. An out-of-round shape also forms a rotation lock. In general, however, an assignment clamping force is sufficient as an effective rotation lock.
  • the radius of curvature of the valve membrane corresponds to 0.8 to 1 4 times the valve membrane.
  • the invention then relates to a container closure produced in the plastic injection molding process with a self-closing valve, a valve membrane and a plate part covering the valve membrane on the product side, and proposes that the plate part be relative to the valve membrane is arranged movably. It is also favorable here that the plate part is spring-loaded relative to the valve membrane, also in this case in the function as a pressure catch spring.
  • a further solution variant results from the fact that the plate part is formed in one piece with the container closure and that the specially designed valve is held in the container closure. This justifies a particularly simple solution in terms of production technology.
  • a hinged lid is formed on the container closure, which acts on the valve membrane in the closed state by means of a hold-down device. This leads to excellent product protection even in times of warehousing or shipping.
  • an advantageous further development of the object according to claim 18 is that the plate part and integrally formed connecting spring arms can be pressed against one another in such a way that mass leakage is prevented. At most, outgassing can take place.
  • This is based on a structure similar to an iris diaphragm, in that the plate part and the spring arms connected to it can be adjusted relative to one another in such a way that a closed state is achieved regardless of the valve membrane.
  • a radially outwardly projecting closure screen is formed on the plate part, against which the connecting spring arm can be closed and further in that an inwardly projecting closure screen is formed on the mounting ring and / or the wall of the dispensing container. against which the connecting spring arm can be tightened.
  • the control means is such that on the connecting spring arm a guiding web protruding on the product side is formed, which cooperates with a run-up slope of the wall of the dispensing container.
  • a hinged lid or the like is unnecessary.
  • the rotary handle can be provided by wing-screw-like conformations of the support ring, which is outlined here, however, which in this way has a further function.

  • FIG. 3 shows a section corresponding to FIG. 1 of a variant of the self-closing valve
  • FIG. 6 shows a container closure in a top view, with the hinged lid open and the valve membrane not yet assigned
  • 10 is a vertical section through the center of the container closure with an associated valve, 11 shows a lip position of the slot walls of the dispensing slot which provides air compensation,
  • Fig. 14 a locking device including the pressure spring, in section, largely schematic.
  • the self-closing valve V has a valve membrane 1. It consists of a patch of elastic, resilient material.
  • the patch is punched out of a flat sheet, preferably in a circular disk shape.

  • the product bears the reference number 6 and is in particular of a liquid or pasty type.
  • the convex curvature seen from the product side exerts a gaping effect on the product slot 4. This creates a notch-valley-like gap 7 in the delivery slot 4.
  • the slot walls 4 'of the same area of the delivery slot 4 visibly assume a diverging orientation towards the product 6 to be delivered.
  • the curvature tension is used, which occurs as a gap-forming tensile fiber.
  • neutral fiber there is an upsetting effect, so that the diaphragm walls 4 'in the gap base 8 lie against one another in terms of edges. It is accordingly the case that the convex shape is accompanied by the internal stresses impressed on the valve membrane 1, especially since the valve membrane 1 extends convexly into the edge region 9.
