Definitions

  • the invention relates to a dispensing closure for containers with a base element for attachment to a dispensing element of a container comprising a dispensing opening and with a lid area.
  • Dispensing closures for containers in particular for containers containing flowable material, are known in a variety of designs in the prior art and are used for beverage containers made from different materials, in particular from glass and plastic.
  • the dispensing closure for containers comprises a basic element for fastening to a dispensing element of a container, the basic element preferably being designed as a fastening collar. Furthermore, the dispensing closure comprises a lid area which adjoins the Basic element connects in order to preferably form a substantially closed, often substantially cylindrical delivery closure.
  • At least the lid area of the dispensing closure is produced by means of a multi-component method, a first component forming a lid element and a second component forming a frame for the lid element.
  • such a delivery closure according to the invention can be adapted particularly flexibly to its mode of operation and its requirements, since a total of two components are available, each of which can be optimized largely independently of one another for specific functions or requirements.
  • These functions include both user functions, such as the wish to use such a delivery closure as a dosing unit or dosing cap, as well as requirements for e.g. To understand the stability of the dispensing closure.
  • the second component designed as a frame ensures the shape and / or stability for the lid area of the dispensing closure, while the first component can be optimized for a certain functionality or visual effect, even if this optimization or Adaptation of the first component would lead to the selection of a material or a design of the first component which would not or could not meet these stability and / or shaping requirements without the second component designed as a frame.
  • such delivery closures according to the invention can also be produced very simply and inexpensively, for example using the injection molding process, each component being able to be produced independently of the other component, and the two components can only be connected to one another in different ways, for example by means of adhesive, molding, and / or frictional engagement, heating and melting of the two components with one another, etc., or also production in a common process step or successively is conceivable.
  • the first component consists of a less stable but generally lighter material which forms an essentially closed, cap-shaped cover element can, but can also extend substantially between the individual frame elements and the basic element of the dispensing closure.
  • the wall thickness of the first component can also be chosen to be greater, equal or also smaller than that of the second component.
  • the second component is generally preferred to produce the second component from a material with a thicker wall thickness than the first component, the second component thereby meeting the requirements of the lid area of the dispensing closure with regard to stability and / or shape, while the molding of the lid element can be carried out by the first component independently of this by means of a material with a very thin wall thickness.
  • the total weight of the dispensing closure and the amount of material to be used can be greatly reduced, which leads to a significant cost reduction, which leads to considerable savings, particularly in the case of such a mass product as a dispensing closure.
  • the total weight of a delivery closure is usually the decisive cost factor and therefore of outstanding importance.
  • both when designing the two components in different wall thicknesses, both, as mentioned above, different materials can be used for the individual components, but it is also possible in principle to use the same materials for both components and only the wall thickness and / or the structure to train differently. Furthermore, it is not necessary for the frame and / or the cover element to have constant wall thicknesses throughout; rather, it is also possible to provide individual parts within a component with greater strength than other parts of the component, in order to, for example, particularly critical areas of the dispensing closure with regard to stability, which are often exposed to stress, particularly to reinforce or at the same time to save material in other areas.
  • a preferred wall thickness for the second component in the form of a frame is between 0.5 mm and 3 mm, a particularly preferred wall thickness is preferably in a range of approximately 1 mm, the wall thicknesses being able to vary depending on the size of the dispensing closure and the materials chosen and in principle there is a tendency to choose a somewhat larger wall thickness for larger-sized dispensing closures.
  • wall thicknesses are preferably selected which are less than 0.5 mm and preferably in a range between 0.1 mm and 0.3 mm.
  • the first component can also be a film which can have very thin wall thicknesses in the range of less than 0.1 mm, possibly less than 0.01 mm.
  • Materials are preferably selected for the first component and the second component which have the lowest possible specific weight, the specific weight of the second component forming the frame preferably being higher than the specific weight of the material of the first component due to the stability requirements.
  • this is not absolutely necessary because a stable construction depends not only on the specific weight of a material, but in particular on the rigidity, breaking strength, etc. of the material, especially since the geometric shape and structure of a material can lead to increased stability.
  • the first component forming the cover element consists of a softer material than the second component. Since the first component, as explained above, does not have to meet increased stability requirements due to the frame, a softer material can be selected which, on the one hand, can have a lower weight and, on the other hand, is more pleasant for the user of the container or the dispensing closure when handling is and leads to a so-called "soft-touch effect".
  • the first component in particular is at least partially transparent. This has the advantage that the dispensing closure according to the invention can also be used as a metering cap or dispensing closure in order to fill the dispensing closure with flowable filling material and to read off the filling quantity. For this purpose, it is also possible for there to be certain measuring lines on the outside and / or inside of the dispensing closure which, for example, indicate the fill level of the dispensing closure in ml or in arbitrary units.
  • the first component is made completely transparent, so that it can be seen from the outside through the dispensing closure from as far as possible from each side.
  • the second component of the dispensing closure it is also possible to make the second component of the dispensing closure partially transparent.
  • the first component forming the cover element is preferably designed as a continuous wall, corresponding regions of this first component must also be transparent in addition to the regions of the second component which are transparent.
  • first component forming the cover element continuously and completely, but only to allow it to extend between elements, for example webs or struts of the frame, so that in cross-section parts of the cover area of the dispensing closure e.g. are formed sector-like only by the second component, in which case it is sufficient if only this area of the second component is transparent.
  • the second component, which forms the frame preferably consists of at least one, preferably at least two, webs which form a structural or stability frame, with the webs of which the first component can be connected on the inside, outside or side edges thereof.
  • the webs of the second component forming the frame are preferably formed circumferentially around or on the cover area and are also connected to the base element of the dispensing closure, so that the base element and the webs of the frame form a stability unit.
  • the webs of the frame preferably extend essentially over the entire height of the lid area and preferably also over an upper side of the lid area, so that the lid area is held essentially completely by the webs of the frame.
  • the webs run essentially frame-shaped or, conversely, U-shaped and preferably run through an axis of rotation of a rotationally symmetrical cover area of the dispensing closure.
  • One or more webs can be provided, which run around the cover area of the dispensing closure, the individual webs each being offset from one another by specific angles.
  • the webs run essentially at equidistant angular distances, wherein they preferably cross at a center on the top of the lid area of the dispensing closure.
  • the webs are preferably designed in such a way that they form a lattice structure which surrounds the lid area of the dispensing closure, as a result of which special stability and special aesthetic effects are produced.
  • the second component forming the frame of the dispensing closure according to the invention is formed on an outside, while the first component forming the essentially closed cover element is formed in the inner region of the frame.
  • Such a dispensing closure is preferably produced in one piece by injection molding, the frame for the lid area with the base element, that is to say the second component, first is produced and then sprayed or overmolded with the first component.
  • the second component has only a small proportion of the surface coverage of the cover area, which is just sufficient to achieve the desired stability and / or shape, while the larger part of the cover area is covered by the first component.
