Definitions
- the invention relates to a slot closing valve for container openings or the like. According to the preamble of patent claim 1.
- the invention relates in particular to self-closing and opening valves for installation in an opening in a container or for completing a closure cap.
- a slot closing valve is known (see e.g. EP-A-0 743 259) which can be provided in one piece by two-component injection molding of different thermoplastic materials in one operation.
- the significant manufacturing advantages resulting from this are opposed by the fact that the return of a container provided with such a valve to the initial configuration, after the container has been compressed to exert a pressure on the contents of the container, often does not take place completely or only after a long time. since there can be no pressure equalization between the inside of the container and the outside.
- Various alternative designs of self-closing valves with a pressure compensation function have therefore already been proposed (see e.g. DE-U-298 17 571, 298 18 414).
- a closing element that is designed and arranged in a special way is required for closing an outlet opening that is not slit-shaped.
- the advantage of a targeted pressure equalization is thus purchased through a design of the valve which is less favorable in terms of production.
- the slot closing valve according to the invention is characterized by the features of claim 1. Accordingly, the diaphragm part of the slot closing valve is designed such that a wall area of the diaphragm part is connected to the base part at an acute angle. One or more slot-shaped through openings are provided in the area of the connection point. These through openings serve the purpose of creating a pressure equalization by allowing ambient air to enter the interior of the container when underpressure conditions prevail in the interior of the container.
- the slot-shaped through openings are kept closed in the event of an overpressure in the interior of the container, so that the overpressure can only manifest itself in a release of the slot-shaped outlet opening in a central area of the membrane part, for example.
- the slot closing valve according to the invention has a particularly simple, uncomplicated structure and, including the said openings, can be produced economically in one operation, for example by injection molding.
- a configuration of the slot closing valve which further promotes production and at the same time promotes the functions mentioned provides that the membrane part can have a pointed roof-shaped configuration.
- FIG. 1 is a top view of a slot closing valve constructed according to the invention
- Fig. 2 shows a section along the section line II-II in Fig. 1, and
- FIG. 3 shows a section along the section line III-III in FIG. 1.
- the slot closing valve comprises a base part bearing the general reference number 1 and a membrane part which carries the general reference number 2.
- the base part 1 has an annular configuration and serves to mount the slot closing valve in an opening to be closed in a container or a closure cap or the like.
- the membrane part 2 is integrally formed on the base part 1 at a suitable intermediate location between the axial ends of the base part 1, preferably close to an axial end, as indicated at 7, and preferably has an essentially pointed roof-shaped configuration, as can be seen in particular from FIG. 2 can be seen.
- the membrane part 2 accordingly comprises side wall regions 3, 3 'which are inclined inward at an angle ⁇ with respect to an inner circumferential surface 6 of the base part 1, which may be concentric with the central longitudinal axis of the slot closing valve. Furthermore, the membrane part 2 has a central ridge area 4, which is preferably in a radial plane to the central longitudinal axis. A slot-shaped outlet opening 5 is made in the ridge area 4.
- the slit-shaped outlet opening 5 has a unidirectional extension along a transverse main axis of the slit-closing valve, but a different orientation of the slit-shaped outlet opening 5 can also be provided if desired.
- the slot-shaped outlet opening 5 could be designed in a multi-directional manner, for example by extending along both transverse main axes of the slot closing valve.
- Fig. 1 shows the slot-shaped outlet opening 5 in the closed position, which is taken in the rest position of the slot closing valve due to the inherent elastic property of the material from which the slot closing valve is made.
- Preferred materials are rubber-elastic materials, such as elastomer, silicone material, or natural or synthetic rubber material and the like.
- thermoplastic elastomers are preferred because of their good processability by injection molding.
- the side wall regions 3, 3 ' have a thickness that tapers from the ridge region 4 in the direction of the connection point 7 and creates a sealing lip-like structure near the connection point 7.
- a slot-shaped through opening is introduced into the side wall regions 3, 3 'at diametrically opposite points of the ridge region 4, as indicated at 8, 8' in FIG. 1.
- Each through opening 8, 8 ' has a unidirectional orientation in the circumferential direction of the membrane part 2 and represents a slot which in the The closed closing valve is kept in the closed state by the inherent elastic properties of the resilient material from which the side wall regions 3, 3 'are made.
- the number and arrangement of the slot-shaped through openings 8, 8 ' is not restricted to the embodiment described above and shown in FIG. 1. Rather, more or fewer than two slot-shaped through openings 8 could also be provided, and furthermore the angular distance between adjacent slot-shaped through openings 8 could be other than diametrical.
- the slot closing valve constructed as described above works as follows. If the valve is fluid-tightly mounted on a container (not shown), e.g. is pressed sealingly into a container opening, all slot-shaped openings 5 and 8 are in the closed position and persist in this position as long as no external forces act on the slot closing valve. If, in this starting position, a squeezing force is exerted on the container, which compresses the container wall to a certain extent, the excess pressure which arises in the interior of the container exerts a force on the membrane part 2, which can result in the slot-shaped outlet opening 5 being spread. The contents of the container can therefore be discharged to the outside via the slit-shaped outlet opening 5 as long as the excess pressure acts.
- the slot-shaped outlet opening 5 will deform back into the closed position due to the elastic restoring behavior of the resilient material and the interior of the container is hermetically sealed from the outside environment.
- the container contents cannot pass outward through the slot-shaped through openings 8, 8 ', since the through openings 8, 8' remain closed by the lip-like end sections of the side wall regions 3, 3 'sealing under these circumstances are pressed against the adjacent circumferential surface 6 of the base part 1.
- the pointed roof-shaped configuration of the membrane part 2 promotes both the closure of the through openings 8, 8 'and also the release of the slit-shaped outlet opening 5, in that the side wall regions 3, 3' are turned outwards in the event of overpressure around their connection points 7 on the base part 1.
- openings 5, 8 can, if desired, be made in an additional step after the basic shaping of the slot closing valve, it is preferred that the openings are made together with the shaping of the slot closing valve. This can be accomplished in that, at suitable areas of an injection molding tool, corresponding to the arrangement locations of the openings 5, 8, cutting elements are moved into the material during the demolding in order to cut into them, which can be used at the same time to carry out the ejection process during a further advance.
- the dimensioning of the slit closing valve and the choice of material should preferably also be carried out in such a way that the locking force for the outlet opening 5 is sufficiently strong that it is not yet brought into the open position under a gradient pressure of the container contents, but only when an external force acts on it Containers that put the contents of the container under an overpressure that is greater than the gradient pressure. A container provided with the slot closing valve could therefore be turned inside out without the contents of the container escaping.
- the membrane part need not have a pointed roof shape. Rather, another suitable curved configuration can also be provided, provided that these enable the Connection of the membrane part to the base part in such a way that said angle ⁇ of less than 90 ° is maintained at least near the through openings.
