Definitions

  • the invention relates to a flexible closure membrane for closures of containers filled with liquid products, the opening slot opening when pressure is applied and tightly closing when pressure is released.
  • liquids Numerous different types of packaging or containers for non-solid products are known, in particular for flowable, liquid or liquidized materials including liquids, creams, powders etc., hereinafter referred to as liquids. Some of these packagings contain a self-closing dispensing valve, which allows a certain amount of liquid to be dispensed from the pack and then resealed to seal the pack.
  • a problem with known containers of this type is to obtain a balanced relationship between the packaging container, the valve and the liquid product, so that the product can be dispensed repeatedly without any particular effort and at the same time only the amount that is desired by the user emerges, particularly as a function of it of the type of the filled product. For example, if you want to dispense a highly concentrated liquid product. such as hand washing soap, the user typically requires a small amount or a drop of soap per application in order to achieve a satisfactory result. In contrast, if other liquid products are used, for example skin cream, face masks, etc., larger amounts of the product are regularly required for each application.
  • the ability of the valve to open quickly and without delay upon light pressure on the container is just as important as the ability of the valve to quickly and safely close again when the pressure has decreased. Equally important is the pressure release that must be applied to the product container to force the liquid through the valve when it is open.
  • the object of the invention is to provide a solution with which, on the one hand, while maintaining the advantages of the known sealing membrane, independent of the filling level of the container, guarantees a correct product removal and on the other hand, a metered, in particular dropwise, product leakage is also possible.
  • this object is achieved according to the invention in that at least one hole is provided in the area of the closure membrane which can be freely flowed by the liquid product.
  • the membrane slot which closes tightly, is opened again to the desired extent.
  • This makes it possible, on the one hand, to allow dropwise metered product outlet by simply placing the product container overhead, without having to exert pressure on the container side walls and to generate a surge of liquid.
  • sufficient and good ventilation of the interior of the container is also ensured by one or more holes in the closure membrane. The consequence of this is that when the container side walls are relieved and the membrane slot is closed, the negative pressure in the interior of the container is reduced and the container side walls bulge again. In this way, the product container can be pressurized from the side or from the bottom again and again until complete emptying. so that the membrane opens and releases the desired amount of liquid.
  • the at least one hole in the region of the closure membrane which can be flowed freely by the liquid product can in principle be arranged at different points.
  • a hole is arranged in the intersection area of at least two opening slots. This offers the additional advantage that the drop-wise product delivery takes place exactly in the center of the sealing membrane and the direction of discharge of the product container, and the product can thus be dispensed in a particularly targeted manner.
  • at least one hole is arranged in the region of a holding jaw of the closure membrane. This has the advantage that when the valve is actuated under pressure, the holes automatically seal, so that a surge of product is then only released through the opening slots.
  • the number and arrangement of the hole or holes are expediently chosen as a function of the viscosity of the liquid contained in the product container.
  • the diameter of a hole is also selected depending on the viscosity of the liquid product between 0.5 and 1 mm. On the one hand, this leads to the desired possibility of dropwise product delivery as well as to the necessary ventilation of the interior of the container.
  • a closure membrane provided according to the invention with at least one hole in the region of the closure membrane which can be freely flowed by the liquid product is particularly suitable as a closure for the product outlet of a liquid product container.
  • FIG. 1 shows a cross section through a closure membrane, shown in simplified form, in the closed state in a product receptacle indicated only on one side in regions,
  • FIG. 2 is a partial enlargement of Figure 1 in
  • FIG. 3 shows a cross section and a top view of a second closure membrane with two intersecting opening slots and holes arranged at their end points and in
  • FIG. 4 shows a cross section and a simplified top view of a further closure membrane with a hole arranged in the intersection area of two opening slots.
  • a closure membrane according to the invention serves as a closure for the product outlet of a flow indicated only in regions. sigeckiviers 2.
  • the closure membrane 1 has a central head region 5, which merges into a circumferential thickened edge 3 via a circumferential holding jaw 6.
  • This thickened edge 3 serves to fasten the closure membrane to the container 2.
  • the container 2 has a circumferential groove 4 in the outlet area, which is formed by the container 2 and a ring 2a fastened to it in a suitable manner.
  • the thickened edge 3 is axially widened radially outward (approximately triangular in cross section), the groove 4 of the container 2 having a corresponding shape.
  • the thickened edge 3 of the membrane 1 is first inserted into the area of the groove 4 formed by the container 2, then the ring 2a is put on and attached to the container 2, e.g. bounced up. The closure membrane 1 is then held securely and close to the container 2.
  • the closure membrane 1 has, in a known manner, at least one opening slot 8, which opens when pressure is applied.
  • pressure is exerted by the user on the side walls of the container 2, not shown, by hand, as a result of which the membrane 1 with its head region 5 initially recedes bulges outside and then the opening slot 8 opens, allowing product to escape.
  • This opening process is described in detail in EP 0 545 678 A2, to which reference is made to avoid repetitions.
  • the closure membrane 1 is provided in the freely flowable area with at least one hole 7, which is recessed in the embodiment of FIGS. 1 and 2 in the region of the holding jaw 6.
  • This hole 7 provides ventilation for the container 2, which is otherwise sealed by the membrane 1.
  • FIG. 3 shows a second embodiment of a closure membrane according to the invention, the same reference numerals being used as in FIGS. 1 and 2 if the same or similar parts are affected.
  • FIG. 4 shows a further embodiment of a closure membrane 1 according to the invention.
  • this membrane 1 two cross-shaped opening slots 8 are again provided.
  • only one hole 7 is provided in this embodiment, which is recessed in the crossing area of the two opening slots 8.
  • the holes can be located at practically all locations on the sealing membrane, the only thing that is important is that they lie in the area that the liquid product can freely flow against.
  • At least one hole arranged according to the invention can be located both in the area of a rigid closure membrane as well as a movable valve membrane, which protrudes outwards when pressure is exerted on the container outer walls, and the like. It is essential that even if the opening slots are otherwise sealed, air can flow into the interior of the container outside of the actuation state and dropwise product leakage is possible in the case of overhead positions of the product container without exerting pressure.

Abstract

Une membrane d'obturation (1) flexible munie d'au moins une fente (8) destinée à la fermeture de récipients remplis de produits liquides, la fente s'ouvrant par application de pression et se fermant lorsque la pression est relâchée, doit permettre d'une part, quel que soit le niveau de remplissage du récipient, une distribution impeccable du produit et d'autre part aussi un dosage du produit à la sortie, en particulier goutte-à-goutte. Cela est obtenu grâce à un trou (7) au moins ménagé dans la zone de la membrane d'obturation (1) librement balayée par le liquide.
