Definitions

  • the invention relates to a plastic tube closure, with a lower part designed as a tube shoulder, which consists of a material that can be welded to the tube body and has an outlet opening, and a closure part designed as a hinged closure, by means of which the outlet opening can be closed.
  • Such a tube closure is well known in the prior art. For example, it is used as a closure for toothpaste tubes.
  • Plastic tubes are regularly made from a film, which can be multi-layered and have a moisture-impermeable layer.
  • the tube grains are regularly produced in such a way that a rectangular film, the length of which corresponds to the length of the tube body, is welded on its long sides to form a cylindrical body. If one end of the cylindrical body is welded closed, a tube body that is open on one side is created.
  • the lower part of the tube closure which is designed as a tube shoulder, is welded onto the open end of the tube body.
  • Plastic tubes therefore often have a tube closure, the lower part of which is welded to the tube body has a thread, onto which a closure part is screwed.
  • a plastic tube for toothpaste in which the lower part of the closure, which is made of polyethylene and welded to the tube body, has a catch element on the circumference, as a result of which the closing part made of polypropylene can be snapped onto the lower part.
  • the closure part made of polypropylene is designed as a hinged closure.
  • a plastic tube can be provided with a hinged closure, but the production is quite cumbersome.
  • the tube closures are manufactured in a separate facility from the tube production.
  • the tube closures are therefore regularly supplied to a tube manufacturer as supplied parts. Since the closure part of the last-mentioned tube can only be impacted onto the lower part after the lower part has been welded to the lower part, the lower part and the closure part must be delivered separately. This is disadvantageous, since the tube manufacturer has to carry out a further operation by applying the closure part to the lower part.
  • the closure part is connected to the lower part in such a way that the edge of the lower part which can be welded to the tube body is freely accessible.
  • the tube closure can thus be delivered to the tube manufacturer as a finished unit in the pre-assembled state. This has a particularly favorable effect on the costs.
  • the closure part can be made of a different material than the lower part.
  • the lower part can therefore consist of polyethylene, which means that it can easily be welded to a tube center.
  • the closure part can be made of polypropylene, which has very good properties with regard to a film hinge.
  • the closure part can therefore be designed as a hinged closure.
  • the closure part has a plug element which is connected to the closure part via a hinge. Furthermore, the lower part has a first recess in which the plug means is arranged. As a result, the closure part can be mechanically connected to the lower part in a simple manner.
  • the tube closure can be produced in such a way that it can be welded to the tube body very easily when the closure part is connected to the lower part.
  • the plastic tube closure according to the invention can therefore be produced as a one-piece closure which is designed as a hinged closure and can nevertheless be welded very easily to the tube body. If the plug connection is designed so that the plug element sits completely in the recess, so that essentially nothing can be seen of the plug element, a closure can be formed in a simple manner in which the closure cap has a different color than the lower part.
  • the closure part is made of a plastic with a different color than the color of the bottom part. Since there is no longer anything to be seen of the plug element, only the closure part has a different color than the lower part.
  • the closure part can be connected to the lower part in such a way that the plug element and the recess are designed in such a way that the plug element sits positively in the recess.
  • the plug element is held in the recess by means of a raster. In this way, a particularly firm connection of the closure part to the lower part can be achieved, which is particularly advantageous when the tube is used later.
  • a further special embodiment of the invention provides that a securing element is provided which is connected to the lower part via predetermined breaking points and engages around the closure part in the state in which it closes the outlet opening such that the closure part cannot release the outlet opening without destroying the predetermined breaking points.
  • a securing element is provided which is connected to the lower part via predetermined breaking points and engages around the closure part in the state in which it closes the outlet opening such that the closure part cannot release the outlet opening without destroying the predetermined breaking points.
  • the securing element is designed as a tab which is attached to the lower part at the point diametrically opposite the first recess.
  • the tab has a second recess into which a nose-shaped projection engages, which is arranged on the closure part at the point opposite the hinge.
  • a plastic tube closure consists of a base 1 made of polyethylene and a closure part 2 made of polypropylene.
  • the lower part 1 and the closure part 2 are essentially designed as round parts.
  • the lower part 1 has an edge 1a, with which the lower part 1 can be welded to a tube body made of polyethylene.
  • the closure part 2 is designed as a cap, which has a plug element 4.
  • the plug-in element 4 is connected to the cap of the closure part 2 via a film hinge 5.
  • the lower part 1 has a first recess 6, which is designed as a trough, the depth of which extends in the axial direction of the lower part 1.
  • a small undercut 9 is formed on the side wall of the trough-shaped recess 6 approximately transversely to the depth of the recess.
  • a correspondingly formed projection on the side wall of the plug element 4 engages in the undercut 9.
  • the first recess 6 and the plug-in element 4 are designed in such a way that they can be positively connected to one another.
  • the lower part 1 has an opening 3 which extends in the axial direction and which forms the outlet opening of the tube.
  • the lower part 1 is designed so that the area having the opening 3 has the shape of a pin.
  • the closure part 2 has a circular web 11 at the base of the cap.
  • the web 11 has at its end facing away from the substrate a thickening extending in the direction of the center of the circle.
  • the web 11 and the pin of the lower part 1 surrounding the outlet opening 3 are designed so that the web 11 can snap onto the pin, whereby the outlet opening 3 is sealed.
  • the lower part 1 has a securing element 7, which is connected to the lower part 1 via predetermined breaking points 8.
  • the securing element 7 is designed as a tab which is connected point-wise to the lower part 1 on one longitudinal side.
  • the closure part 2 has at its point opposite the hinge 5 a nose-shaped projection 10 which, in the state closing the outlet opening 3, engages in a second recess which is formed at a corresponding point in the securing element 7. If the nose-shaped projection 10 is located in the second recess of the securing element 7, the closure part 2 can only be folded away from the lower part 1 after the securing element 7 has been removed, as a result of which the outlet opening 3 is opened.
  • an indentation 12 is formed on the circumference at the point opposite the hinge 5.
