  • CONTAINER UNIT CONTAINER AND METHOD FOR MANUFACTURING SUCH CONTAINER
  • the invention relates to a container unit with container and closure element, as well as threadless container and a method for producing such containers. It particularly relates to a container with a separate thread, such as aluminum cans and bottles for daily life needs.
  • Aluminum cans and bottles, so-called monobloc cans, are produced in a manner known per se from one piece of a starting material, for example by extrusion or deep-drawing.
  • the starting material is brought into the desired container shape with the appropriate shapes and methods.
  • a part of the spout area of the container is formed as a thread on which a screw cap can be screwed.
  • rolled threads in Fliesspress process the inner coating of the container material is damaged, which leads to porosity in the paint and makes the container useless for many applications.
  • containers with a separate threaded ring are only of limited use since, in the case of such closures, the lid and threaded ring usually make a very strong connection. In an attempt to open the container, does not open the screw cap, but it turns the threaded ring on the neck. This happens even when, for example, a mechanical closure of the container. For closures with strong closing force containers are thus used with integrated thread, in which an opening is guaranteed.
  • a container and a container unit is to be created, which guarantees a secure holding a closure on the container. It is also an object to provide a method for producing such containers.

  • the closure element and the container or only the closure element structures. If the structures are introduced only in the closure element, they are arranged or configured in such a way that the structures, together with the thickening in the container edge, effect a positive retention of the closure element on the container. If the closure element and the container have structures, then these are designed to correspond with one another in a form-fitting manner.
  • a closure element is secured against axial movement and / or rotation relative to a container.
  • the structures in the spout area of a container are an identical negative or positive to the corresponding structures in a closure element.
  • Such structures are molded into a container in a process step of the manufacturing process in a spout area of the container.
  • the container can be made in an otherwise known manner by, for example, cold presses or deep drawing in metallic material or by molding or casting, for example in glass.
  • the structure is preferably designed in such a way that a closure element which can be attached to the otherwise threadless spout area of the container, such as a threaded ring or a complete closure relative to the container, can be secured against rotation by positive locking.
  • Non-threaded containers generally have the advantages that no threading in the container itself must be made. In the case of flow-molding processes, an elaborate production step can be saved and, in addition, the injuries of an inner coating lacquer occurring during the thread forming process are eliminated. With separate threaded rings also containers without integrated thread can be provided with a screw cap. It can thus also be provided with complex threaded or closures for a container, which - A -
  • the container according to the invention has the additional advantage that it can be provided with a closure which, even with a high closing force of a lid - which is desirable for a secure closure of a container - guarantees opening of the container. Due to the structure in the container, which corresponds to the structure of a closure element, a closure member securely seated on the container and is secured against rotation due to rotation of the closure or a lid.
  • containers provided with structures are not only suitable for screw closures with a separate threaded ring. It may, for example, a one-piece closure, z. B. snap or click closure are applied or a substantially arbitrarily shaped retaining ring to which a closure is attachable.
  • the structures in a container mentioned here are formations of the container wall, which are arranged on the circumference of a spout area of a container. These structures may be structures formed from a container wall, such as in cold-pressed containers. For containers made of glass, these would preferably be structures on the outer circumference of the bottle neck. Structures on the inner circumference of the container are also possible with appropriately designed closure element. Structures can Recesses and bulges, which can be arranged parallel to an imaginary longitudinal axis of the container or a cylindrical spout area. They are preferably designed such that they can be produced by an axial displacement of a forming the structures forming tool along the spout area. Thus, the length of such a structure can be determined by the amount of feed of the tool.
  • structures may also be hemispherical or square bulges and / or depressions. If the structure is formed from the container wall, as is preferably the case with containers produced by cold extrusion, the depth of the structures, ie the distance between the outer and inner circumference of the spout area, is preferably less than the comparable depth of thread grooves. Due to the lower mechanical stress of the material in the manufacture of such structures, no damage to an interior paint is caused.
  • the structures allow a closure element attached to or at the spout area of a container, which on its inner or outer side to the
  • the structures of container and closure element are arranged so that a rotation of the closure element to the container axis is not possible or only to a limited extent.
  • the structures may additionally be designed so that they also prevent or reduce slippage of the threaded ring along the container axis up or down by their positive connection.

Threaded rings need not be clamped by crimping the edge of an aluminum container with the edge and it can be made with high closure force closures without threading must be introduced into the container itself.
  • structures can be introduced by a single additional method step in the molding process of a container, which is also executable on the same machine as the other production methods, thus creating the conditions for a substantially improved closure.
  • the container or at least one spout area is shaped, e.g. made of glass, only the mold needs to be designed differently, for example. Instead of the thread shape have the shape of the structure.
  • Structures of containers may be identical or partial negatives of structures of closure elements and vice versa.
  • Positive-locking structures in particular in the form of identical negatives / positives, make it possible that in the resting state of the closure, ie when no opening or closing takes place, essentially no pressing of the closure element on the container is necessary. No or only a slight pressure takes less weight on the sealing material and makes plastic hardly deform (cold flow). This increases the selection options in terms of material, especially for low-cost material.
  • a closure element in particular a threaded ring, are made correspondingly thin, so that material can be saved. A flow of the Plastic takes place essentially only upon rotation of a lid, which flow but is stopped by the structures.
  • the structures also serve as cropping elements for inaccurate manufacturing of a container, no thread changes due to manufacturing inaccuracies of the container or aging of the closure are to be expected.
  • An unthreaded container comprises a body, a spout area adjoining the body with a spout opening, wherein the spout area has a thickening, for example a crimp, in the area of the spout opening.
  • the spout area preferably has structures which allow a form-fitting attachment of a closure element, for example a threaded ring or a snap closure.

  • the structures are preferably simple axial, oblong shapes, which allow a parallel displacement of a molding tool relative to the container or the spout area of the container in the manufacturing process.
  • Various possibilities for introducing structures are: i) the structures are pressed from outside the container with a suitably shaped tool, so-called retracted, while the tool is guided axially to the container from the outside; ii) a mold in the form of a core is inserted into the container into the spout opening, while with a counterpart acting on the spout area from the outside, the corresponding structures are crept into the neck region.
  • a core piece includes molds corresponding to the structures to be embossed, but which forms are arranged retractable in the core.
  • An externally applied mold is preferably in one piece and its inner circumference determines the outer circumference of the parts of a container which are processed therewith. But it is also possible to lay multi-part molds around the spout area. By closing the molds, the introduced on the molds structures are transferred to the spout area.
  • Options i) and ii) allow the use of relatively simple tools without moving parts. They are essentially suitable for the introduction of structures which bring about a varying diameter along the circumference of the spout area, but not along the longitudinal axis of the spout area towards the spout opening.
  • a molding tool is guided axially from the later pouring opening, over the container, and thus a round pouring area with a specific first circumference is formed.
  • a second mold is passed over the container in the same way. However, this second tool is only pushed so far over the spout area, that in the spout area an upper cylinder is formed with a narrower second perimeter.
  • a third mold having the structures is passed over the spout area from above.
  • the second narrower circumference of the container is substantially equal to or smaller than the inner circumference of the molding tool caused by the structures.

With a beaded edge, the edge is typically bent by about 90 °, between 90 ° and 180 ° or even up to 360 °.
