Definitions

  • the present invention relates to a closure device made of plastic for attachment to a closed container made of plastic film material, consisting of a lower part with a cylindrical spout and a flange for attachment to the container and a screw cap which is screwed on the lower part, and a cylindrical piercer, which is open on both sides in the axial direction and runs in the spout of the lower part in a thread, wherein in the screw cap means are provided which move the piercer in a helical downward upon first screw movement of the screw cap, and that the cylindrical piercer on the cylindrical wall , at the end which is directed to the container wall, having at least one tooth and a deflector.
  • Closure device of the type mentioned above have been attached to today only made of laminated film material containers. These laminated films have at least three layers of different materials. On the one hand, such a material consists of a cardboard layer, which gives the container the required stiffness, an aluminum layer which serves as an aroma barrier and a plastic layer which the required tightness guaranteed. In order to cut through these three layers, the corresponding piercer of a closing device mentioned at the beginning has to fulfill different functions. In order to cut through the cardboard layer, a plurality of saw teeth are often proposed, while a raised tooth with a front cutting edge cuts through the aluminum layer, while a perforating tooth cuts through the aluminum layer
  • the present invention is a closure device which is applied to a pure Kunststofffolienmatieral.
  • Such tubular bags usually called pouches in technical jargon, have not hitherto been opened by means of the aforementioned closing devices, but instead an opening has already been punched out and a closure has been welded correctly in position with its spout or welded between two film layers.
  • the positional stability of the bottled food or beverage is thus dependent only on the tightness of the closure, such closures have been used practically only in unproblematic areas, in particular in the field of cosmetics.
  • the closure device of the type mentioned the container bag remains completely closed until the time of the first opening. This gives an increased shelf life.
  • plastic films are much more robust and designed with higher wall thickness than the very thin plastic film layer in a laminated film. This results in different requirements for the closure device.
  • Initial tests with sealing devices of the known type gave no reliable results.
  • Plastic films tend to deform much more.
  • closing devices of the known type the cutting teeth have hooked with their perforation tooth in the film and this was stretched. By such stretching, the molecules are directed in thin plastic films and the material is thus much tougher.
  • plastic films of the type of interest tear very easily or can be pierced once, cut, but that the actual penetration of the film through the teeth is problematic. In particular, here the corresponding cardboard layer is missing, which keeps the plastic film in immovable position. The better the foil is pretensioned, the better it can be perforated and then cut open.
  • a closure device of the aforementioned type which has a plurality of cutting teeth uniformly distributed over the circumference, wherein the piercer additionally comprises a deflector whose height is less than the height of the teeth. Consequently, this deflector has only the function of pushing the partially cut-out roundel out of the area of the spout and keeping it in this rejected position, in order to ensure that the round-folded roundel is held outside the spout area.
  • An additional function is neither intended nor conceivable.
  • a similar closure device for a container made of laminated paper or cardboard which in turn has a deflector which is less high than the at least one cutting tooth.
  • This Deflector is additionally provided with a perforating tooth.
  • the corresponding idea is based on the fact that in the case that the plastic film layer is not pierced by at least one cutting tooth, the film is stretched and pressed down, and the subsequent deflector with a perforating tooth can pierce the unstressed film.
  • this solution is based on the fact that the plastic film layer of the laminated paper or cardboard firmly bonded thereto practically does not yield, and consequently, even if the leading teeth have already partially penetrated the laminated paper or cardboard wall, the non-severed layer still approximately at the original height.
  • a closure device according to the preamble of claim 1 which is characterized in that the deflector the at least one tooth, at least approximately surmounted so that at the Clearö réelle this touches the réellemonyde container wall simultaneously or first, simultaneously or before the at least one cutting tooth with the Container wall comes into contact.
  • a certain bias of the plastic film is achieved before the cutting tooth touches the film, so that the cutting tooth with its perforating point can penetrate the film in the tensioned state and then cut it.
  • FIG. 1 - 4 an inventive closure device by itself in the non-mounted on a container state in different opening positions in which the cap unscrewed different degrees and the piercer protrudes differently far from the cylindrical spout over the flange.
  • Fig. 5 shows a development of the puncture according to the invention.
  • FIGS. 1 to 4 show the closure device according to the invention in different opening positions.
  • the piercer 5 of interest here is located completely within the lower part 2 of which, as FIG. 1 shows, practically only one flange 3 can be seen.
  • the closure device 1 consists of three parts, namely the lower part 2, a screw cap 4, which is screwed onto the lower part 2 and a cylindrical piercer in the assembled state is completely in a cylindrical spout 6, which is part of the lower part 2.
  • the cylindrical piercer 5 has an external thread which meshes with an internal thread of the mentioned spout 6.
  • the piercer 5 is driven by means in the screw cap 4, which are not shown here and are not relevant to the understanding of the invention. These means are usually drivers which are in contact with corresponding drivers 11 on the inside of the cylindrical piercer 5.
  • the screw cap 4 is unscrewed, wherein it moves away in the direction of the flange 3 and thus also from the wall of the container on which the closure device 1 is mounted, while the cylindrical piercer 5 with the same direction of rotation, but with opposite set axial component is moved so that the piercer 5 moves out of the spout 6, and thereby opens the wall of the container, not shown here.
  • the starting position shown by the cylindrical piercing 5 and its teeth or at least one cutting tooth 7 and the deflector 10 are completely within the spout 6.
  • the screw cap 4 is partially unscrewed and the piercer 5 projects with its teeth 7 and the deflector 10 beyond the flange 3 of the lower part 2.
  • FIGS. 3 and 4 that layer is shown in which the cylindrical piercing body is maximally screwed out of the lower part, wherein it is still held in the lower part 2 or in its spout 6. In this position, however, the container wall is completely screwed.
  • FIG. 5 shows a development of the penetrator 5 on an enlarged scale.
  • the piercer 5 has a cylindrical wall 15 whose edge 16 directed towards the cap extends straight, while the teeth 7 and the deflector 10 are formed on the edge directed towards the container.
  • the teeth 7 have a, the maximum height defining perforating 8 and an inclined cutting edge 9. From the perforating 8 runs the boundary of the tooth 7, at the edge of the cutting edge 9 remote arcuately towards the edge 17. At least in the region of one of the cutting teeth 7 of the already mentioned driver 11 is formed.
  • This deflector 10 has a leading in the direction of rotation D shoulder 13 which is arranged on the above-mentioned edge 17 at least half the height of a cutting tooth 7 of the aforementioned edge 17 outstanding.
  • the shoulder 13 has correspondingly an upper shoulder edge 18.
  • This shoulder edge protruding follows a rounded edge 14, which forms an elevation 12.
  • This elevation extends at least up to the same height as the at least one cutting tooth.
  • the elevation may, however, also be higher, and this difference in height, ie the distance projecting beyond the at least one cutting tooth, is denoted by Ah.
  • This difference Ah can be between 0 and 15% of the diameter of the piercer 5.
  • the rounded edge 14 this can not get caught with the plastic film and only presses on this, while at the same time tense the plastic film.
  • the elevation 12 is at least as high as the perforation of at least one cutting tooth 7 or slightly surmounted.
  • the leading shoulder 13 acts stiffening by its three-dimensional, rounded shape, while the actually force acting part, namely the rounded edge, only slightly protrudes beyond the shoulder edge 18.
