Definitions

  • the invention relates to a pouring element for a composite pack, comprising: a base body with a flange, a hollow-cylindrical spout that defines a central axis, and a closure part that is formed in the spout and that runs essentially orthogonally to the central axis, with a central area and an annular around weakened zone running through the central area, with a conical ring-shaped intermediate area being formed between the weakened zone and the central area, a hollow-cylindrical cutting element that is movably guided in the spout and has at least one cutting tooth for severing the weakened zone to open the spout and composite pack, a resealable screw cap that opens when it is opened for the first time of the composite package is used to drive the cutting element.
  • Such pouring elements are integrated as part of the top of the composite pack for ease of handling when pouring and for reclosing the composite pack.
  • This type of pouring element is shown, for example, in the applicant's EP-A-2 627 569.
  • the hollow-cylindrical cutting element opens the base body and thus the previously gas-tight package for the first time and thus forms a pouring opening, with the screw cap enabling the now opened composite package to be closed again.
  • the cutting element which is movably guided in the spout, is provided with force transfer elements and is thereby driven by corresponding force transmission elements on the cap.
  • the cutting element approaches the closure part and after the first contact of the two elements, the cutting tooth of the cutting element separates the closure part approximately in the area of the weakened zone.
  • the trajectory covered by the cutting element corresponds to the annular weakened zone.
  • the opening process can be subdivided into the following sections, for example. The approaching of the cutting element mentioned above can also be omitted if the two elements are already touching in the assembled state.
  • the cutting element then moves through the closure part and separates it with the cutting tooth along a cutting line. This ripping process is a combination of ripping, plastic deformation and material displacement, whereby an even and controlled application of forces is advantageous.
  • the cutting element begins to fold the closure part to the side, thus freeing the spout for the contents. Folding away is done using the remaining piece of the weakened zone that has not been severed as a pivot axis, first the cutting tooth and then the outside of the cutting element exerting force on the closure part during the folding away, pushing it aside. After the pouring element has been completely opened, the closure part is approximately parallel to the central axis Z along the outer wall of the screwed-in cutting element.
  • pouring elements with such a closure part are mainly, but not exclusively, used in aseptic packages.
  • previously sterilized foodstuffs are packaged under aseptic conditions in packaging that has also been sterilized, in order then to obtain so-called aseptic packages.
  • aseptic packages Apart from the question of aseptics, there are various types of composite packs into which a pouring element according to the invention can be integrated.
  • the pouring element is an integral part of the composite package which is incorporated during the manufacturing process thereof.

  • the flange can be connected to one side of the packaging jacket by another plastic element that is injection molded directly in the packaging machine.
  • the flange can also be welded or even glued directly to the packing shell without using an additional plastic element.
  • the flange can either be the same size as the opening of the packing jacket or smaller in order to be able to save plastic. In the case of a smaller flange, the faces of the packing skirt must be folded together and then placed against the flange and welded.
  • the composite pack then preferably has polyhedron-shaped gable surfaces which are connected in a corresponding manner to the polyhedron-shaped flange of the pouring element, the polyhedron-shaped flange essentially corresponding to a truncated pyramid.
  • an initially completely sealed composite pack is produced, with a punched hole being present in the composite pack, mostly in the gable area, into which a pouring element is introduced.
  • the pouring element is usually introduced by welding the flange to at least one layer of the composite material, but alternatively these parts can also be glued.
  • This second type of composite pack is characterized above all by the fact that the pouring element can be introduced independently of the production of the composite pack. The production of the hole and also the introduction of the pouring element can therefore take place before, during or after the production of the composite pack itself. Both steps are preferably carried out prior to manufacture in order not to unnecessarily complicate the packaging machines themselves.

  • Such composite packs are therefore also referred to as cardboard/plastic composite packs.
  • the pouring element is integrated as part of the composite packaging, it should have a similar high level of gas and light barrier properties as the composite material used. At the same time, of course, cheap materials should be used that are easy to recycle together. This also applies in particular to the materials used for the pouring elements.
  • the present invention is based on the object of designing and developing the pouring element mentioned at the outset and previously described in more detail in such a way that the disadvantages described are overcome despite the given choice of material.
  • a pouring element having the features of the preamble of patent claim 1 in that the cutting element and the closure part are designed such that at least part of a projection of the cutting tooth lies parallel to the central axis on the intermediate area.
  • the object is also achieved by two design variants of a composite pack for liquid foodstuffs, which is designed in such a way that a pouring element according to the invention is integrated into the respective gable area of the composite pack.
  • This arrangement of the cutting element and the parts of the closure part enables a clearly defined and smooth cutting process by supporting the cutting tooth at the intermediate area.
  • the closure part When the closure part is folded away, the application of force to the conical ring-shaped intermediate area ensures that this process is initiated cleanly on the one hand, but that the closure part is later folded completely to the side.
  • the cutting element and the closure part are designed in such a way that the cutting tooth strikes the intermediate area and exerts force on it when the composite pack is opened for the first time. This is the case because the cutting element, while rotating around the Central axis » moved towards the closure element (parallel to the central axis).
  • the projection thus defines the radial position at which the cutting element strikes the various areas of the closure part and which are largely separated during the course of the opening process.
  • the cutting element does not only hit the weakened zone, but also the intermediate area lying radially further inside and separates the closure element there.
  • the weakened zone is still the thinnest area of the closure element and is therefore preferably severed by the cutting element, but the arrangement and design of the base body and cutting element according to the invention ensures that the closure element is separated cleanly and in a controlled manner.
  • the folding away of the closure element at the end of the opening process can also be facilitated thanks to an increased lever of the application of force from the inner wall of the spout.
  • a further teaching of the invention provides that the weakened zone has less than 50% of the height of the central area measured parallel to the central axis. This guarantees a clean opening of the weakened zone, combined with a stable central area that can also be folded completely to the side at the end of the opening process.
  • the weakened zone extends between an inner radius and an outer radius, essentially orthogonally to the central axis.
  • a base body with a weakened zone designed in this way is easier to produce and also enables the thin area to be separated and opened in a more controlled manner.
  • a further embodiment of the invention which further intensifies these effects, provides that the difference between the inner radius and the outer radius is at least twice as great as the height of the weakened zone, measured parallel to the central axis.
  • an inner radius of the hollow-cylindrical cutting element should be at most 95% of the inner radius of the
  • the weakened zone connects directly to the grommet.
  • this enables simplified production of the base body because the transition area between the spout and the closure part can be shaped more beautifully.
  • the forces during the ripping process are better transmitted and absorbed by the grommet.
  • the cutting tooth is ground on the inside at the end facing the weakened zone.
  • a cutting blade on the cutting tooth which on the one hand facilitates immersion in the closure part and on the other hand forms a surface corresponding to the surface of the conical ring-shaped intermediate area, which is therefore arranged approximately parallel thereto.
  • the corresponding surfaces of the cutting tooth and the intermediate region come into contact as the cutting element moves along the central axis and at least part of a projection of the cutting tooth along the central axis lies on the intermediate region. This then guarantees better power transmission over a larger area from the cutting element to the intermediate area.
  • a further teaching of the invention provides that the grinding of the cutting tooth changes continuously with respect to and along the central axis from a beveled inner surface to an inner surface formed parallel to the central axis.
  • the cutting tooth extends at the end facing the weakened zone in the circumferential direction in a plane orthogonal to the central axis.
  • the flattened end of the cutting tooth ensures that the cutting tooth separates the weakened zone more stably and is guided along the intermediate area. If the part of the projection on the intermediate area is so large that this end extending circumferentially in a plane orthogonal to the central axis is located over the intermediate area, it also ensures that this cutting edge of the cutting tooth is directed outwards cleanly from the intermediate area until it Goes to an area thin enough to be severed, such as the weakened zone itself.
  • a further embodiment of the invention is that the cutting element is thickened radially inward in the area of the cutting tooth. Reinforcement in line with the cutting tooth ensures that the forces generated during the various opening phases are easily absorbed. This is particularly useful because the cutting tooth is a protruding part of the cutting element and thus tends to break off. Adaptations of the cutting element that relate to the severing process, such as those set out in the previous statements, are mostly located in the area of the cutting tooth. In most cases, however, it is sufficient to locally limit such changes in order to be able to save as much material as possible in the rest of the cutting element. In this sense, each reinforcement of the cutting element can be regarded as a thickening, which is formed protruding inwards on the hollow cylinder and has, for example, a maximum of 95% of the inner radius of the rest of the hollow cylinder.
  • At least 30%, preferably at least 50%, of the surface of the cutting element facing the Be covered intermediate area parallel to the central axis of a projection of the cutting element makes sense in order to further enhance the effect of the invention. In this case, it makes sense to use the projection of the entire cutting element for the definition of this overlap, because it rotates around the central axis and the cutting tooth therefore also moves along the entire intermediate area.
  • the cutting element has two cutting teeth.
  • a cutting element will go through the severing phase more quickly and move on to folding away the more cutting teeth are formed on it, provided these are distributed reasonably regularly over the circumference.
  • the opening force increases with each additional cutting tooth that simultaneously pierces the closure part with cutting teeth of the same length.
  • an injection molding point on the central axis of the closure part.
  • the individual components of the pouring element are manufactured using the injection molding process.
  • a mold with a negative mold of the part to be produced is filled with liquid plastic, which then solidifies before the mold opens and the finished part is ejected.
  • the liquid plastic is fed through a single nozzle, upon ejection the solidified molded plastic part separates from the rest of the plastic still in the nozzle. Of course, this separation can also take place before ejection via the nozzle itself.
