Definitions

  • the invention concerns a rotary closure for a container, a bottle, especially a medication bottle or the like according to the preamble of claim 1 and the EP 40 797.
  • the EP 40 797 discloses a rotary closure for a container with a screwed on cap and a plurality of layers, the lowest being sealed or glued to the rim of the opening of the container.
  • One of the inner layers becomes accessible when the cap is removed.
  • This layer is provided, on its lower surface, with a layer of glue and may be detached from its lower neighbor layer, to which it is glued.
  • This neighbor layer is provided with an opening, not to confuse with the opening of the container, which becomes accessible and/or usable when the upper layer(s) are removed.
  • the FR 2 943 321 discloses a multilayer film, where some of the layer(s) may be peeled off from the other(s).
  • the firm is provided in form of a plate or liner which is sealed to the rim of an opening of a container and has a flap where one may have a good grip to start with the peeling action. Upon peeling the film in two layers, openings are provided in the lower part, which remains on the container.
  • a group of publications are mentioned as fundamental but not generic prior art, which include, among many others, CA 2,179,840, DE 37 06 962, EP 1 046 595 and EP 1 278 630. All these documents disclose the use of plates or liners with which removal openings of any container are sealed, the liners being designed multilayered and it being possible to separate them along a predetermined contact surface between two generally multilayered layers.
  • the upper layer has a tab for grasping and weakening lines are provided in the lower layer, which are generally closed so that during the peeling off process along the contact senses the material of the lower layer remains on the upper layer in this closed area and the removal opening defined by the weakening line is formed.
  • EP 1 462 381 pursues a different strategy: it also uses a two-layered liner within a screw cover, which after tightening of the screw cover and liner is sealed on the vessel edge by induction or heat transfer. The upper layer of the liner is then firmly joined to the screw cap; the lower layer already has finished openings and therefore fails completely as a barrier layer or the like. During first opening the two layers are separated and the layers sealed to the vial or container together with its opening already produced in the factory is available for removal of the product. The making of holes before mounting of the liner in the screw closure can be mentioned as au essential shortcoming here, since this must occur with corresponding position accuracy. Perforation must even occur before joining the two layers to the endless material of the liner material.
  • U.S. Pat. No. 2,646,183 going back to the year 1950, uses a two-layered liner in which the two layers to be separated are only weakly joined to each other (glued), in which case the lower layer was glued (according to the technique at that time during first screwing on of the screw cap together with liner) to the container edge. Since the upper layer was very strongly glued to the screw cap, the weak glue joint between the two layers rupture during first opening hut the layers that have neither a weakening line nor an opening remaining on the container had to be perforated by hand or by means of a spoon, knife or the like.
  • the lower layer was therefore included in producing the harrier effect but because of the forced destruction during first opening the result was not a defined removal opening for the corresponding product but de facto a crack, a split or the like and, during the completest possible removal of the lower layers up to the filling opening, residues of the layers generally remained glued to the container edge, which is optically undesired, especially in medications.
  • the EP 40 797 does not disclose any connection between the cap and the upper layer of the liner and that, the FR 2 943 321 discloses no cap at all.
  • closed weakening line means that, the weakening line encircles an area in form of a circle, a triangle, a pentagram or any similar regular or irregular shape. It is of importance to mention that, the weakening line known from the already mentioned U.S. Pat. No. 4,719,740 is not closed.
  • the adhesive can then preferably be applied by a priming method so that precise adjustment of the glue sites said therefore precise geometric coordination occurs with application of the weakening line.
  • the adhesive force can also be adjusted by the printing method over broad limits precisely to predetermined values.
  • An additional line namely a separation line essentially passing through the liner material, is preferred, corresponding to the outline of the interior of the screw cap in order for the liner to fit during introduction in the screw cap.
  • the adhesive can be provided in almost arbitrary fashion without adversely affecting the invention, serving there for holding the two layers together with precise position.
  • FIGURE shows a schematic top view of a section from an endless material that already has the two layers in joined form.
  • the areas provided with adhesive between the two layers are drawn in this example with a dark color in the purely schematic (as stated) top view. Two areas are involved, which serve as markings 1 for positioning of the liner material 2 during production and assembly.
  • a central glue site 3 is arranged within a closed weakening line.
  • the weakening line 4 has a circular shape, the center of the circle is as congruent as possible with the screw axis of the screw cap into which the liner is inserted. In this way undesired shear forces are avoided during first opening.
  • a separation line 5 is provided concentric to weakening line 4 , which need not actually entail complete separation of the lower and/or upper layer, but which restricts the mechanical stability of the liner material 2 as a whole so that during introduction into the screw cap full separation of both layers occurs along this line and the liner broken out or punched out from the liner material 2 comes to lie on the interior of the screw cap and with the outer layer comes to lie on the inner face of the screw cap, covering its surface as much as possible, and is firmly and reliably glued or welded to it.
  • the area outside the separation line 5 does not enter the closure cap and does not belong to the closure and this part of the liner material 2 after introduction, of the litter into the screw cap is disposed of.
  • the large-area annular glue site 6 outside the separation line 5 serves for precise fixation of the two layers relative to each other to obtain geometric correlation. Since no effect on the later liner occurs from areas outside the separation line 5 , the glue surface here 6 can he modified in a variety of ways, for example. In several rings or a number of glue points and it is also possible to create additional glue sites in the areas that are the corner areas of the liner material 2 present as endless material in the FIGURE.
  • Example for thickness/ Cap inside basis weight A) PET (polyethylene 5-50 ⁇ m terephthalate) B) Adhesive see below C) CPP film (unstretched 70-140 ⁇ m polypropylene) (preferably around 100) D) Adhesive see below E) Aluminum foil 6-50 ⁇ m (preferably around 30) F) Adhesive, optionally see below colored G) Sealing film 15-100 ⁇ m Container edge
  • blown PP or orientated PP may be used with good results, too.
  • the glue is, for example, one- or two-component glue based on polyurethane and other peelable glues can also be used.
  • the employed amounts as known to one skilled in the art, can vary over a broad range and lie between 0.001 g/m 2 and 5 g/m 2 .
  • weakening line 4 gluing of the layers must occur strongly tram the cap to the sealing film G, since all these layers A-G mast remain in this area on the cap. Outside the weakening line 4 gluing between the layers being separated, i.e., either glue layer F or D, is provided weakly or not at all, in order to permit separation along this contact surface.
  • This weakening line is to be applied from the side of the sealing film G which must be separated anyway and the aluminum foil on the one hand, must also be mechanically weakened in this case but, on the other hand, must completely fulfill its barrier property reliably in the area of the weakening line.
  • a weakening line 4 designed in this way the aluminum foil E remains joined in its entirety to the cap and during first opening carries along the material of sealing film G placed within the weakening line.
  • the glue joint between the sealing layer and aluminum foil is designed strongly within the weakening line 4 but is weak or not present at all outside of it.
  • the weakening line may be created by any way known in the prior art, preferred by use of a laser beam, or a high energy ion beam, or by using a mechanical tool, e.g. a cutting tool.
  • a mechanical tool e.g. a cutting tool.
  • the man skilled in the art knows which technology to use when he or she takes into account the kind of container and the kind of goods.
  • the invention concerns a rotary closure for a container, like a bottle, especially a medication bottle or the like, which in the original closed state has a rotary cap that is screwed onto the opening of the container, in which case a liner that closes the opening is provided between the circular face of the inside of the rotary cap and the annular face of the opening, which has at least two multilayers independent of each other, which are in surface contact with each other along a contact surface, which optionally contains glue, in which case the upper layer initially lies in the rotary cap and is joined to it at least in the central area, of the face and in which the lower layer is firmly joined to the annular face of the opening and in which the liner has a weakening line 4 , characterized by the fact that the weakening line 4 is closed and leads around the central part of the face and that in the area of the contact surface within the weakening line 4 joining of the two layers is strong and it is not present or only weak outside of the weakening line 4 .
