Definitions

  • the present invention relates to a one-piece plastic closure with a hinge for containers, consisting of a lower part with side walls and a final cover surface of an outlet spout arranged therein, and a cap connected to the lower part via the hinge, which seals the outlet spout.
  • a hinge for containers consisting of a lower part with side walls and a final cover surface of an outlet spout arranged therein, and a cap connected to the lower part via the hinge, which seals the outlet spout.
  • both the side walls of the cap and the side walls of the lower part are perpendicular to the top surface and to the base of the lower part. Only under these conditions was it possible to produce a plastic closure of the type described with a plastic injection mold without a slide.
  • a closure which is characterized in that the side wall part in which the hinge is arranged runs inclined to the base surface of the lower part, the outlet grommet passing through the top surface running parallel to that side wall part.
  • a tube consists of a cylindrical sleeve which is welded to a tube head.
  • the tube head has an outlet nozzle on which a shoulder section adjoins, the outside diameter of which corresponds to the inside diameter of the tube sleeve.
  • the tube sleeve is welded onto the collar of the tube head.
  • Known closures for tubes have so far been on the outlet spout of the tube head.
  • the tube heads are provided with an external thread on the outlet nozzle.
  • the general structure of the plastic closure according to the invention is known. Such closures are attached to many bottles. They have a lower part 1 which can be placed on the container neck and a cap 2 connected to it in a hinged manner. The lower part 1 and the cap 2 are connected to one another via a film hinge 3 and on the other hand via one or more spring elements.
  • two tensioning straps 4 which run parallel to one another and are arranged on both sides of the film hinge, are provided as spring elements. The straps 4 are offset with respect to the film hinge 3 towards the center of the closure, whereby the snap action of the closure is achieved (Figure 4).
  • the tube sleeve which is only partially shown, is designated by T. It consists of a plastic laminate film. The usual tube head is missing here because of the lower part of the closure here this function takes over. The outermost edge of the lower closure part 1 is tapered approximately by the thickness of the plastic laminate film, so that the overlap area 5 at which the film is welded to the lower part is barely recognizable in its contour
  • FIG. 5 This is a vertical section through the closure according to FIG. 4.
  • the lower part 1 has the shape of a truncated cone, which is formed by cutting a straight circular cone.
  • the cone axis K is the normal in the center of the circular base surface 6.
  • the top surface 10 is inclined to the cone axis K. The inclination of the top surface 10 is chosen here so that the top surface runs perpendicular to the side wall part 11 'in the area of the hinge 3.
  • the cap 2 does not completely cover the top surface 10 of the lower part. This uncovered part 12 of the cover surface is shifted slightly parallel downwards relative to the covered part 10.
  • the lower edge of the circumferential side wall 11 has a wall thickness which is reduced by the film thickness of the tube envelope T.
  • the part of the cover surface 10 covered by the cap 2 is penetrated by an outlet grommet, which is designated overall by 13.
  • the part 14 of the outlet spout 13 lying above the top surface 10 has a larger diameter than the part 15 of the spout 13 lying below the top surface 10 Create room 18 below the top surface 10. This enables the admixture of a material that is located in the space 18 into the strand of the second material that comes from the tube sleeve T.
  • a recessed grip 26 is provided in the area opposite the hinge. This recessed grip is formed in that the cap 2 on the side remote from the hinge 3 has a wall section 27 parallel to the wall section 11 'of the lower part 1 in the area of the hinge 3.
  • an integrity guarantee element can also be realized with the closure according to the invention.
  • the guarantee element is molded over predetermined breaking points on the lower part and engages in the form of a positive and / or non-positive member on the cap of the closure when it is first closed, so that the closure can only be opened when the predetermined breaking points are destroyed.
  • closure according to the invention is particularly advantageous for use on tubes, it is not limited to this.
  • the aesthetic design of a closure is of crucial importance.
  • the present invention gives the packaging specialist additional freedom which he can take full advantage of without increasing the cost of the closure.
  • top surface 10 extends perpendicular to the wall part 11 'in the area of the hinge S, this is not a condition. It is even possible to lay the top surface 10 parallel to the base surface 6.
  • FIGS. 7 and 8 are used only for illustration. As a reminder, the axis of the outlet nozzle is shown in broken lines.
