Definitions

  • the present invention relates to a screw cap made of plastic and a container made of plastic or soft material with a spout, the screw cap having a guarantee band arranged on the lower, peripheral edge, which is connected to the lower edge of the jacket wall of the screw cap via predetermined breaking webs.
  • Screw caps of the type mentioned have been known for many years. Last but not least, their design depends on the material from which the container on which the closure is placed is made. In the case of glass bottles, the spout is usually standardized and the screw caps must therefore conform to the standard. For plastic containers, the spout can be varied much more freely. Also for containers made of so-called soft material, plastic spouts are used, which in turn can be manufactured with great design freedom.
  • the invention relates to screw caps that with Interact containers made of plastic or soft material, the spout is made of plastic and the screw cap and spout are coordinated.
  • Containers made of soft material can be tubular bags made of plastic films or containers made of coated cardboard, or in particular also containers made from multilayered laminated film materials.
  • multilayer laminated films consist, for example, of a paper or cardboard layer, which are designed with plastic films and an aluminum foil layer laminated.
  • predetermined breaking bars are extraordinarily thin material bridges, in the area of which the molecular chains are aligned during the spraying process. These molecular chains now run in the direction of the predetermined breaking webs and have their highest resistance in the exact direction.
  • Snap hinge locks are also known in a wide variety of configurations, which can be placed on specially designed plastic containers, in particular also screwed on.
  • guarantee straps with a pull tab are provided on the lower part of the snap hinge closure, which can be placed on a suitably designed container neck to prevent rotation. This is to prevent the twist lock from being removed from the container without opening the snap hinge lock and from being put back on afterwards.
  • all of these fasteners have a tamper-evident tape with a tear tab, and the tamper-evident tape must first be hand are removed, after which the snap hinge closure can be brought into its position of use.
  • An example of such a closure is shown in US-A-4,722,444.
  • FIG. 1 shows a vertical diametrical section through a first embodiment of a screw cap according to the invention with a spout placed on a container made of soft material and
  • Figure 2 the same spout with unscrewed cap
  • FIG. 3 again shows a vertical diametrical section through a slightly modified spout.
  • Figure 4 shows a perspective view of the screw cap with spout according to Figures 1 and
  • Figure 5 also shows a perspective view of a reduced version of the closure
  • FIG. 6 shows a side view of the spout of Figure 2.
  • FIG. 7 shows a variant of a spout as seen from above and
  • FIG. 8 shows a screw cap in a vertical position
  • the screw cap 1 can in principle be designed conventionally. It thus consists of a circumferential cylindrical jacket wall 7, which is closed at the top by a cover surface 50. An annular sealing bead 51 can be provided on the underside of the top surface 50.
  • the jacket wall 7 is provided with an internal thread, which is preferably designed here as a fine thread 17. This fine thread 17 need only be provided in the lower region of the jacket wall 7.
  • a guarantee band 5 is formed on the lower edge of the jacket wall 7 via predetermined breaking webs 6.
  • the guarantee band 5 can, as in the embodiments according to FIGS. 1, 2 and 4-6, be designed to widen conically downwards. Such a design is aesthetically satisfactory on the one hand and also has the advantage of particularly simple demolding.
  • guarantee bands which are arranged in alignment directly under the jacket wall of the screw cap
  • the guarantee band 5 can, however, also be arranged running parallel to the axial direction of the twist lock, as is shown for example in FIG. 8.
  • the guarantee tape must be offset outwards by at least the wall thickness of the screw cap.
  • the spout is always drawn as a separate part. However, this is by no means mandatory.
  • the spout can of course be made in one piece with a plastic container.
  • the shape of the spout 2 shown here consists of an annular wall 9, at the lower end of which a flange 8 is formed. This flange 8 is arranged perpendicular to the annular wall 9.
  • the flange 8 would practically represent the container itself, and the spout 2 would accordingly form a bottle neck.
  • An external thread 10 is formed on the outside of the ring wall 9, which is also preferably designed as a fine thread. The thread 10 also does not extend over the entire length of the ring wall 9.
  • a form-locking means 11 is formed on the spout 2 between the external thread 10 and the flange 8 arranged at the bottom.
  • this form-locking means 11 has the shape of cams 12 projecting radially outwards.
  • the guarantee band also has recesses 13 of approximately the same size.
  • the cams 12 pass through the recesses 13, which are designed here as openings 15.
  • the cams 12 mentioned overlap a part 19 of the guarantee band 5 which engages behind the same, as can be clearly seen, for example, in FIG. 2 and in FIG. This has the advantage that the guarantee band remains held on the spout 2 even after the guarantee band 5 and the screw cap 1 have been separated.
  • the manufacture of such a spout still requires slides because the manufacturing mold or the injection mold engages behind the cams 12.
  • the form-fitting means 11 can also be designed in the form of a rib, as is shown in FIG. 3.
  • These ribs 16 preferably run radially outwards on the one hand and parallel to the center axis of the spout 2 on the other hand.
  • These ribs 16, which are correspondingly considerably narrower than the cams 12 described and shown above, are in the closed state of the closure in a positive connection with the guarantee band 5 of the screw cap 1.
  • the form-fitting means 11 on the spout 2 is designed in both versions so that the lower edge of the Screw cap 1 stands directly on the cam 12 or on the ribs 16 in the assembled state. This means that the recesses 13 run with their upper edge in the parting plane T between the guarantee band 5 and the lower edge of the jacket wall 7. This situation can be clearly seen in FIGS. 5 and 6. This embodiment is used directly as a stop during assembly. This will be discussed later.
  • FIGS. 7 and 8 A last embodiment is shown in FIGS. 7 and 8.
  • the spout 2 is again designed as a separate part. Since the spout is shown here from above, the flange 8 is clearly visible.
  • the ring wall 9 with its external thread 10 At its innermost is the ring wall 9 with its external thread 10, which is also designed here as a multi-start fine thread.
  • the term fine thread is used in plastics technology and the person skilled in the art knows what it means, but no direct definition is known.
  • a fine thread has a relatively low thread height, which is definitely smaller than the normal thread, as is known to everyone, for example, with glass bottles. Compared to the ring wall 9 with the fine thread 10, a concentric ring of circumferential fine toothing 20 is clearly visible.
  • This fine toothing 20 corresponds to the form-fitting means 11, for example in the form of cams 12 or ribs 16, as previously described.
  • the matching screw cap 1 is designed accordingly. Their embodiment is shown in Figure 8.
  • the screw cap 1 is designed with a jacket wall 7, which is closed off from above by a cover surface 50.
  • the closed, strap-free guarantee band 5 is integrally formed over predetermined breaking webs 6 by the thickness of this jacket wall 7.
  • This guarantee tape 5 is provided with fine toothing 18, which corresponds to the fine toothing 20 on the spout 2 in the grid.
  • the internal thread again designed as a fine thread 17, is arranged on the jacket wall 7, the internal thread, again designed as a fine thread 17, is arranged.
  • the two parts of the spout 2 and the screw cap 1 only have to be aligned axially with one another, while the relative angular position of the two parts relative to one another is completely meaningless.
  • the preferred fine threads 10 and 17 allow the threads to slide over one another without problems and with relatively little force.
  • the fine toothing 20 on the spout 2 and the fine toothing 18 on the guarantee strip 5 is such that even if the two toothings are not exactly one hundred percent aligned when the two teeth collide, the two parts automatically align with one another.
  • the correction angle is only 3-6 °.
  • the fine toothing which is practically the same as reefing, can be provided with a kind of Einlaufra pen 21 at the bottom of the guarantee band in order to facilitate this running into one another.
  • Such an assembly is extremely fast and the assembly device required for this is correspondingly simple and inexpensive. Since the screw cap closures shown here are used especially for containers made of soft material, the quantities are extremely high.
  • the form-fitting means 11 or 12, 16 are only distributed around the circumference at a few points. In a first step, this in turn requires axial alignment with one another and then relative angular positioning of the two parts with respect to one another, before the two parts can be pressed against one another again by a simple translational movement in the axial direction.
  • the assembly can be simplified by placing the screw cap 1 on the spout 2 and then turning it until a stop element, not shown here, in practice indicates the correct angular position of the two parts to one another, followed by an axial Translation the end position is reached.
  • the screw cap 1 When such a screw closure is opened for the first time, the screw cap 1 can only be rotated by a shear force acting immediately on the predetermined breaking webs 6. This shear force occurs immediately without first stretching these predetermined breaking webs in their longitudinal direction.
  • the molecules, which are already directed in the predetermined breaking webs, can be opened with relatively little effort due to the practically 100% shear force. This makes screw cap closures easy to open, even for older people or children who do not have a lot of strength in their hands.

Abstract

Les capuchons filetés actuels dotés d'une bande de garantie se déchirent généralement par une languette ou bien la bande de garantie recouvre un bord du contenant et, lors du dévissage, tous les ponts des points destinés à la rupture se déchirent dans leur sens longitudinal. Selon l'invention, le contenant ou son ouverture de versement (2) sont pourvus de parties radialement saillantes se présentant sous forme de moyens de liaison de forme (11, 12) qui s'insèrent dans des évidements correspondants (13, 15) de la bande de garantie du capuchon fileté et empêchent toute rotation mutuelle. La rotation du capuchon fileté génère un mouvement de cisaillement sur les segments destinés à la rupture (6) qui sont peu résistants à ces forces.
