Definitions

  • the present invention relates to sealing device made of plastic for attachment to a closed container made of film material, consisting of a spout part with spout and a flange for attachment to the container and a cap which can be placed on the spout part, and a cylindrical piercing with an external thread in axial direction is open on both sides and runs in the spout of the spout into an internal thread, wherein in the cap at least one driver is present, by means of which before the initial opening of the cap, the piercing screw is movable downwardly, and that the cylindrical piercer on the cylindrical wall , At the end which is directed in the assembled state to the container wall, at least one cutting tooth (12) is formed.
  • tubular bags On the market today, a large number of tubular bags are represented, but the majority of which are made of multilayer films, especially such films, the at least one layer of paper, a layer of plastic and a layer Have aluminum. These tubular bags are relatively pressure-resistant and are designed predominantly cubic.
  • tubular bags which consist only of plastic film
  • tubular bags are common as refills for cosmetics.
  • Tubular bags that are made of pure plastic film usually either have no closure and for removal, only a portion of the tubular bag is cut away and the contents of the tubular bag transferred to a container, or alternatively, tubular bags are made of plastic, which have a flange with spout and a pure screw cap attached to it.
  • Plastic closures consisting of a lower part with a spout and a cap connected to the lower part via a hinge, are available on the market in any number of variants, but their attachment to tubular bags is out of the question.
  • Plastic bag made of plastic are highly flexible and accordingly act on these during transport and handling relatively large Forces that lead to deformation of the tubular bag and increase the internal pressure accordingly.
  • Hinge closures are usually unable to withstand these forces. For safety reasons, therefore, today usually only plastic closures are used on tubular bags as pure screw caps.
  • closures which are known for example from WO 2004/000667, WO 2004/083055, EP 1533240, EP 1795456 or CH 695019, have a cylindrical piercing, which is open on both sides in the axial direction and the at least one driver on the cap when unscrewing the cap moves axially in opposite directions down while cutting the film of the bag within the range of the spout. As soon as the film of the tubular bag is cut open, it works
  • Closure device as a simple screw cap. These screw caps are now opened and closed several times during use. Now, as soon as the actual opening of the tubular bag is done, it would thus be desirable if the cap away from this moment as a simple Swivel hinge lock could act. However, this is not possible with the previously known closures.
  • Schwenkschnappscharnier can act. It is a further object of the present invention to provide a closure device which is operable after the first opening and thus the opening of the tubular bag both as Schwenkscharnierver gleich as well as, if the tubular bag should be transported again after the initial opening, as a screw cap actuated in a secured position can be brought.
  • the first object solves a closure device with the features of claim 1.
  • the second object and other objects solve closure devices with the features of the dependent claims.
  • the closure device according to the invention is designated overall by 1. It is mounted on a film of a closed, bag-like container B. The attachment is preferably carried out by means of ultrasonic welding, but can also be done by gluing.
  • the closure device 1 consists of a spout part 2, a cylindrical piercer 5, and as a third part, a pivoting hinge closure 20th
  • the spout part 2 comprises a cylindrical spout 6 at the lower edge of a radially outwardly directed flange 3 is formed.
  • the cylindrical part of the spout part 2 is referred to here as a spout 6 and is integrally connected to the aforementioned flange 3.
  • the spout 6 has an internal thread 8, in which the yet to be described, cylindrical piercing 5 is movably guided.
  • the outside of the spout 6 is designed thread-free. Only in the lower region, just above the flange 3 and extending approximately parallel to this, a circumferential retaining collar 13 is arranged directed outwards.
  • the already mentioned internal thread 8 of the spout 6 has a rectangular, trapezoidal shape.
  • the inclined edge of the trapezoid is inclined towards the upper end of the spout 6, so that the piercer 5 can not be screwed during assembly but can be pushed in like a ratchet.
  • the cylindrical piercer which essentially has the shape known from the prior art, has an external thread 7, which mates with the external thread 8 of the spout 6. The piercer 5 can thus be moved helically downward in the spout 6 of the spout part 2.
  • the piercer 6 with its cylindrical wall 11 has a lower edge, which is designed overall as a cutting edge, and has at least one cutting tooth 12, which lies directly above the film of the container B prior to the first actuation of the closure device 1.
  • a driver 10 On the inside of the cylindrical wall 11 of the penetrator 5, a driver 10 is formed.
  • This driver 10 consists of an elongated, inwardly directed element.
  • a pivoting hinge closure 20 On the spout 6 or on the spout part 2, a pivoting hinge closure 20 is placed.
  • Pivot hinge closure 20 is in one piece, but has a lower part 21 and a cap 24, which are connected to each other via a pivotal connection 22, but preferably via a clamping wall belt 23 pivotally connected to each other.
  • the cap 24 has a cover surface 26, on whose lower, inwardly directed side a driver 9 is formed.
  • This driver 9 is practically over its entire, directed from top to bottom, length to a corresponding driver 10 of the piercer 5 at.
  • the Swiveling hinge closure 20 can be rotated relative to the pouring part 2.
  • the axial, relative altitude, at least the lower part 21, relative to the spout 6 does not change.
  • the lower part 21 has positive locking means 25 which cooperate with corresponding positive locking means 13 on the spout 6.
  • This retaining bead is designed in the embodiment shown here in cross section as a nose.
  • the swivel hinge closure 20 can consequently be simply placed on the spout 6 in the assembly machine and pressed straight down, wherein in the end position the retaining bead 25 engages under the retaining collar 13.
  • the swiveling hinge closure 20 can thus be rotated relative to the spout 6, without the swiveling hinge closure 20 altogether changing its relative height to the spout 6.
  • the piercing element 5 is set into a corresponding rotational movement by the two mutually engaging drivers 9 and 10.
  • the piercer 5 screws down and the incisor 12 pierces the film of the self-contained container B and now opens the tubular bag for the first time.
  • the piercer 5 is now screwed down as far as this by means of corresponding latching means, not here are shown, come into engagement, in which position the two drivers 9 and 10 are no longer engaged. In a reverse direction of rotation after the initial opening thus remains the piercer in its locked end position stand.
  • the actual cap 24 of the pivoting hinge closure 20 and the lower part 21 of the pivoting hinge closure are already secured on the one hand via the pivot connection 22 and / or the clamping band 23 against a relative distortion of these two parts. Since the torque between the cap 24 and the lower part 21 may be relatively large, if the user initiates only the rotational movement only via the cap 24, it may be useful to form at the bottom of the jacket wall of the cap 24 downwardly directed tabs 14 which engage in corresponding recesses 27 in the shell wall of the lower part 21. These tabs 14 can simultaneously form a guarantee element, which can be demolished after the corresponding rotational movement. Of course, instead of a tab, a plurality of such tabs 14 are also conceivable, which can engage in corresponding recesses 27.
  • the tabs 14 may also be arranged contiguously on a guarantee strip.
  • the spout 6 may have on its outer side an external thread 30, which only in the region of the cap 24th is available.
  • the cap 24 in turn has an internal thread 28 which cooperates with the external thread 30 on the spout 6. If, in turn, the pivoting hinge closure 20 is rotated during the first actuation, then the relative height of the lower part 21 to the spout 6 does not change, while at the same time, however, the cap 24 performs a relatively small upward movement. This changes the relative height between the cap 24 and the lower part 21. At the same time the tension band 23 is tensioned. The strap 23 now changes the pure
  • the cap 24 After the first opening, the cap 24 will now only be actuated in a pivoting manner. However, it is possible, if you want to close the container in the opened state in turn, and wants to carry this example in a backpack, so it is possible to screw the actual pivot cap 24 by a corresponding rotational movement again. Now the cap 24 practically works again as a simple screw cap. If you want to drink something from the container, so you have to turn the screw movement to move the cap 24 relative to the lower part 21, in turn, the tension band 23 is tensioned and now the cap 24 in turn acts as a pivot cap a SchnappscharnierverInstitutes.
  • solution with a film hinge as a pivotal connection 22 can not be combined with a solution be ' the lower part 21 and cap 24 relative to each other, by means of said threads 28 and 30, to be moved.
