Definitions

  • This invention relates to a self-opener closure for composite packages as well as with foil material to be sealed container neck or bottle neck of all kinds. It is especially thought of liquid packages in the form of such composite packages of foil-coated paper in which about milk, fruit juices, all kinds of non-alcoholic drinks or liquids in general be packed in the non-food area.
  • the closure can also be used for composite packages in which bulk goods such as sugar, semolina or all kinds of chemicals and the like are stored or packaged.
  • This film-coated paper is a laminate material such as a paper or board web coated with plastic such as polyethylene and / or aluminum. Common volumes of such packages range from 20cl up to 2 liters and more.
  • the self-opener closure can also be mounted on containers which are closed by a foil material, for example on all kinds of bottles made of glass or plastic or similar containers.
  • plastic closures are known in various designs (see, for example, document US-A-5 482 176). They form, when they are intended for a composite package, essentially a spout with radially projecting shoulder from its lower edge, which forms a final flange at this spout.
  • the nozzle is equipped with an external thread on which a threaded cap can be screwed as a closure.
  • Such a self-opener closure is flanged onto the composite package by sealingly sealing it to the composite package with the underside of its cantilevered edge, that is, the underside of its flange.
  • the free passage at the lower end of the nozzle is then closed by the paper and the sealing film of the composite package.
  • the spout is in turn plugged or screwed onto a bottle mouth and closed on its inside with a foil membrane.
  • the nozzle is equipped with an external thread on which then the threaded cap can be screwed as a closure.
  • the film-reinforced paper passing through below the welded-on nozzle or the film membrane running inside the nozzle must be cut open, torn open or pushed away to open the passage and allow the liquid or bulk material to be poured out of the container through the nozzle.
  • a sleeve is arranged in the interior of the nozzle, which is entrained when turning the screwed cap of this and is therefore rotated by this in the same direction of rotation.
  • the slowly downwardly moving and simultaneously rotating sleeve touches with its entire lower edge almost simultaneously to be cut to the foil-reinforced paper web and presses them down and turns on it until a hole is more scraped or broken through clean as cut.
  • slicing is not correct is due to the fact that the film to be sliced avoids the pressure of the sleeve, which acts as a drill bit, downwards and thus the sleeve no longer acts on a flat paper foil, but on a downwardly curved one.
  • the self-opening closure should also allow the automatic metering of a small amount of substance in solid, liquid, granular or powdered form, separate from the contents of the composite package, as soon as the closure is opened.
  • he should also allow the metered addition of a separate solid substance by this is washed out during pouring the contents of the composite package by pouring over the pouring jet and taken away.
  • a self-opener closure for composite packages as well as container orjetnstutzeri to be sealed with film material consisting of a spout nozzle, which is sealingly mounted on a composite package or on a container or bottle neck to be closed with foil material, an associated Rotary cap and arranged within the spout neck self-opening Hutsse, which is displaceable by the rotary cap in rotation, and which is characterized in that the self-opener sleeve at its lower edge and projecting therefrom at least a single combined piercing and cutting member , And that this self-opening sleeve, the spout nozzle and the rotary cap are equipped with guide and power transmission means which cooperate with each other such that the first time turning the rotary cap in the opening direction, the self-opening sleeve first in the spout nozzle without rotation axially ab lakebar and then is rotatable about its axis without axial movement.

  • the spout-neck 2 is welded in a known manner to a composite package, so that the bottom of the flange rests on the composite and is sealingly connected to the same.
  • These guide webs 8,17 serve to ensure that the self-opening sleeve is guided in the interior of the spout neck 2 in the desired manner, as will become clear later.
  • the self-opening sleeve 3 This fits into the interior of the spout-neck 2 and here has a single combined piercing and cutting member 9.
  • This lancing and cutting member 9 is integrally formed here at the bottom of the self-opener sleeve 3. It forms in the example shown an equilateral triangle, wherein the downwardly projecting tip 10 is sharpened and also the remaining free sides of the triangle sharpened edges 11 form. Therefore, this triangle acts as a lancing cutter 9, as will be described below.
  • guide ribs 21 which serve to force the self-opening sleeve 3 under the influence of the torque acting on them in a certain movement.

  • FIG. 2 initially shows the rotary cap 1 of the self-opening closure in a perspective view approximately from below and separately shown.
  • This rotary cap 1 is here equipped with two oppositely disposed, concentric with the axis of rotation of the rotary cap 1 cylinder wall segments 5, which are integrally formed on the inside of the cap lid 16.
  • it can also be three cylinder wall segments, which are arranged distributed over the circumference.
  • the cylinder wall segments 5 are each in each case all identical, but specially shaped. Namely, the lower edges of the segments 5 have two portions ascending in opposite directions, wherein these rising edge portions 13, 14 are offset axially with respect to the rotary cap 1, so that a step 15 is formed in the middle.
  • the first edge portion 13 seen here in a counterclockwise direction starts to rise from the level of the cap lid 16 and ends after a peripheral portion of 90 ° of the cylinder wall segment 5, in the case of three segments after a peripheral portion of 60 °, about this section about 2 / 3 the height of the cylinder wall segment 5 increases. This height corresponds approximately to 1.5 times the thread height at the threaded cap 1.

  • the counter-rising edge portion 14 of the cylinder wall segment 5 begins to rise at the level of the lower beginning of the step 15 and extends to the upper end of the step 15.
  • this edge portion 14 extends by slightly less than 90 ° along the circumferential direction of the cylinder wall segment fifth , which therefore extends in total by approximately 180 °. In the embodiment with three cylinder wall segments, the edge portion 14 extends correspondingly by a little less than 60 ° and a single cylinder wall segment then extends by approximately 120 °. Between the cylinder wall segments 5 and the inner wall of the rotary cap 1 remains so much space that there on the one hand, the wall of the spout nozzle 2 as well as arranged in the interior of the spout-neck 2 self-opener sleeve 3 space.

  • FIG. 4 shows the self-opening sleeve 3 separately from obliquely below, but shown in a different rotational position than in FIG.
  • the self-opening sleeve 3 is dimensioned in diameter so that it fits into the interior of the spout neck 2, wherein the guide ribs 21 each come to lie in those places in the spout 2, where it has no guide webs 8,17.
  • a second lancing cutter 9 is shown here by dashed lines. Above the pierce cutter 9, one of the U-shaped guide ribs 21 is arranged.
  • FIG. 5 shows the self-opener closure in the assembled state, viewed directly from below. It can be seen first, the flange-like projection 7 and in the interior of the spout-neck 2, the concentric inserted self-opener sleeve 3 and also concentrically arranged cylinder wall segments 5 on the inside of the lid 16 of the rotary cap 1. It recognizes both the guide ribs 21 on the self-opening sleeve 3 and the lancing cutter 9 and the optional second lancing cutter drawn in dashed lines. In addition, one recognizes the guide webs 21 on the outer wall of the spout nozzle, which alternate around the entire circumference. Next, the two diametrically opposite driving cam 12 are visible.
  • a bridge-like web connecting the two driving cams 12 shown in the drawing has the advantage that the self-opening sleeve can be sprayed from the middle of the web. It then has namely a central injection point, which generally facilitates the plastic injection and a higher strength of the molded part results as a gating over so-called side gates, so laterally arranged spray nozzles. Such are necessary in the embodiment shown.
  • the part shown in Figure 5 is thus injected from two opposing spray nozzles and the injected plastic must converge in the injection mold cavity and connect intimately.
  • the design without a bridge has the advantage that the spout remains free and does not hinder the outflow, while a bridge extends naturally across the spout and thus obstructs the outflow. Depending on the application, it is therefore necessary to weigh up the advantages and disadvantages of a design with or without a bridge.
  • FIG. 6 the assembled self-opening closure is shown from the side, in the initial position, that is, before it is opened for the first time. It can be seen in the starting position, only the rotary cap 1 and the lower part of the spout-neck 2, namely its lower radial projection 7. At the bottom of the rotary cap 1, as shown here have a guarantee strip 25, which has a number of thin material bridges 26 with the rotary cap 1 is connected. This guarantee strip 25 is slipped when first putting the rotary cap 1 on a special bead which rotates the nozzle 2 at the spout nozzle 2 below the external thread.
  • the bead which, however, is not visible here, has for this purpose a rounded upper edge and an edged lower edge, so that the guarantee strip 25, once it is slipped over this bead, no longer back over the bead can be pulled up, because this acts like a barb, but the guarantee strip 25 below this bead completely overflows the spout nozzle.
  • the guarantee strip 25 To open the closure, that is to turn away the rotary cap 1, the guarantee strip 25 must first be torn away while breaking the material bridges 26. Only then can the rotating cap 1 be rotated and unscrewed from the neck 2.
  • FIG. 7 shows the assembled self-opening closure viewed from the side after the axial or vertical depression of the self-opening sleeve in the interior of the pouring spout 2.
  • the piercing cutter 9 now projects completely beyond the lower edge of the flange-like projection 7. also the approximately diametrically opposite, drawn here in dashed lines, if such a second lancing cutter 9 is present.
  • the turning cap 1 can be turned counterclockwise when viewed from above. Accordingly moves in the case of a threaded cap 1 the same at the spout nozzle upwards.
  • the rising edge portion 13 acts on its inner cylinder wall segments 5 on the driving cam 12 on the inserted self-opening sleeve 3 and pushes them down.
  • the one or more piercers 9 come into action and it is exactly the same as a can opener in the first phase.
  • the film or composite package is pierced toward it in a pure vertical motion, at one location, or in two places, in the case of two grooving blades 9. This is very important, because only if the film is initially only pierced, then a clean cut can be achieved with a cutting motion. This self-opener closure makes use of the can opener effect.
  • the tip 10 of the piercing cutter 9 is sharpened and also the circumferentially facing edges 11 of the piercing cutter 9 are sharpened so that the tip 10 when piercing the generated hole in the film or composite package seamlessly expanded on both sides.
  • the edge portions 13 of the cylinder segments 5 have pivoted about 90 ° relative to the self-opening sleeve 3 as well.
  • the self-opener sleeve 3 is guided with its guide ribs 21, namely with their vertical sections 23,24, initially non-rotatably on the vertical sections 18 of the guide webs 8 on the spout 2. Therefore, it is merely pushed vertically downwards by the edge sections 13 of the cylinder segments 5 until the ends of the edge sections 13 have reached the inwardly pointing driver cams 12 on the self-opening sleeve 3.
  • the steps 15 come at the lower edges of the cylinder wall segments 5 in action and put the self-opening sleeve 3 in a horizontal rotation about its axis of rotation by these stages 15 push the driving cam 12 in front of him ,
  • the self-opener sleeve 3 is guided along the horizontal portions 22 of its guide ribs 21 and 19 of the guide webs 8 at the spout 2.
  • This rotation in the horizontal plane now causes the lancing cutter 9 to act as a pure cutting member by the sharp edge 11, which faces in the counterclockwise direction, the clean cut film or composite package clean.
  • the cutting rotation extends over almost 360 ° in the case of a single engraving cutter.
  • the almost 360 ° rotated self-opener sleeve 3 has thereby cut out a disk of the film or composite material and as a result of its rotation by approximately 360 °, this disc is pivoted downwards and releases the flow.

Because the two lancing cutters 9 are not arranged exactly opposite one another, the one lancing cutter 9 then intersects a section through which the second has already cut, while this second end leaves a small section of the foil undurched, around which then the cut-out foil disc 27 is swung off

  • the rotary cap 1 does not necessarily have to be a threaded cap, but the principle of this self-opener closure also works with a rotating cap that forms with the spout nozzle about a bayonet. It must be less steep then only the slopes of the edge portions of the cylinder wall segments on the inside of the cap lid.
