Definitions

  • the present invention relates to a self-opening plastic closure consisting of a spout with a flange for connection to a single or multilayer packaging film of a closed package, with a movably guided inside the spout cylindrical cutting member, and a screw cap with a shell wall with internal thread and a top surface, said the screw cap with the spout with external thread is screw-connected and the screw cap and the cutting member have means that implement the screwing of the screw cap in a purely translational relative movement of the cutting member to the spout.
  • Self-opening plastic closures are closures that are welded or glued on a completely closed container made of a single or multi-layer packaging film and have a cutting member which cuts open the packaging film when the screw cap is first screwed on and holds it in an open state. The reclosability of the Closure is then effected only by the screw cap.
  • Plastic closures of this type have been practically on the market for about 20 years. Already in one of the earliest applications of a closure of this type two different types are disclosed. In particular, such self-opening plastic closures are provided either with a rotating cutting member or with a cutting member which performs a purely translational movement. This latter type is already out of the EP 0328652 known, which discloses the features of the preamble of claim 1.
  • the cutting member is axially guided in the spout and has on an upper edge a ramp-like feed device which presses with a corresponding ramp-like end face of a ring wall segment when unscrewing the cap of this cutting member down.
  • the cutting member has a plurality of perforating teeth, which are distributed over the entire circumference, except for a short portion which is without teeth, to avoid that the packaging film is completely separated from the packaging and would fall into the container.
  • the problem with such a solution is the force applied here.
  • the entire force to be applied must be practically applied with only a quarter turn of the screw cap. Because of the high forces that are required, such a Closure to open, these closures have not prevailed in the market.
  • the spout has an internal thread in which the cutting member with an external thread stores.
  • the screw cap which has a circumferential casing wall and a top surface, has arranged on the inside of the top surface at least one driver which cooperates when screwed with a driver on the inner wall of the cutting member and now the cutting member screwed down while the screw cap is unscrewed upwards ,
  • the cutting member has a plurality of perforation teeth, all of which also act simultaneously on the packaging film. Again, a very large force is needed to perform the opening, but here requires less force through a much longer sterweg.
  • Another variant is from the EP 2 055 640 known.
  • the delivery of the cutting element in a first step is purely translational by a drive, as already mentioned EP 0328652 known and at the end of the first step, the cutting member is now moved not only axially but also rotationally.
  • a self-opening plastic closure according to claim 1, characterized in that the means provided are a first and a second successive engaging feed mechanism, which cause different axial feed paths per revolution.
  • FIG. 1 is a possible embodiment of the inventive, self-opening plastic closure, which is generally designated 1, shown in perspective.
  • the screw cap 2 whose peripheral jacket wall 20, at the lower end of a corresponding not visible here breaking points bridges a guarantee strip 22 is formed.
  • the circumferential jacket wall 20 carries the upper cover surface 21. Outside of the jacket wall 20 are a plurality of Handle ribs 29 attached, which increase the grip for the user in the operation of the screw cap.
  • FIG. 2 is the same, self-opening plastic closure 1 shown in the assembled state obliquely from below.
  • the self-opening plastic closure 1 In the position shown here, the self-opening plastic closure 1 is shown in an intermediate position, in which the cutting member 4 with the perforating teeth arranged thereon is already slightly protruding from the spout 3, thus the cutting member 4 is at least partially visible.
  • the spout 3 is now partially visible from the bottom, so that now recognizes a mounted on this bottom power line rib 32.
  • the design of the power fins is shown here as a single, circumferential rib, but other design forms of such power fins 32 are known and their design is adapted according to the welding connection to be formed and the material pairing.
  • the screw cap 2 is in the FIGS. 3 and 4 shown individually. Like any screw cap, this also consists of the already mentioned shell wall 20 and the top surface closing off the screw cap 21. Escape under the shell wall 20 is likewise already mentioned warranty band 22, on, not specifically shown here, predetermined breaking points bridges formed.
  • the internal thread 23 on the casing wall 20 This internal thread 23 serves to cooperate with an external thread on the spout 3.
  • a first annular wall 24 which has a different height in this sectional drawing.
  • the first annular wall 24 is higher than to the left of the central axis.
  • the first annular wall 24 is completely circumferential in this embodiment and extends from a lowest point to the highest point, the lowest point being the starting point at the first opening, and the highest point corresponding to an end point after a rotation of 360 °, this being the end point the delivery route of a first delivery mechanism represents.
  • the ramp-shaped first annular wall 24 has a sliding surface 25 facing away from the top surface 21. This sliding surface 25 then cooperates with a second sliding surface of a first delivery mechanism, which will be discussed later.
  • a second annular wall 26 is integrally formed on the underside of the top surface 21. This second annular wall 26 is the same height over its entire circumference.
  • the axial length of the second annular wall 26 is here greater than the axial length of the shell wall 20. This is related to that Screw cap 2 is held in the assembled state with its guarantee strip 22 on the flange 31 of the spout and distanced to this.
  • an external thread 27 is formed on the outside of this second annular wall 26, an external thread 27 is formed. This external thread 27 forms part of a second delivery mechanism.
  • annular wall 26 In principle, four concentric annular walls are formed under cover surface 21, the outermost annular wall representing the lateral wall 20 and the innermost annular wall forms the so-called second annular wall 26. Between the second annular wall 26 and the jacket wall 20 follows from the inside to the outside only the first annular wall 24 and then an annular wall which forms a so-called sealing olive 28 which comes to rest in the closed state of the closure after the first opening sealingly on the inside of the spout. In the mounted state before the first opening, the packaging film is still closed and the sealing function of the sealing olive is not yet required.
  • the spout 3 is in the FIGS. 5 and 6 each represented individually, the FIG. 5 a diametrical section shows and FIG. 6 is a perspective view with a view from above into the spout into it.
  • the spout 3 consists of a cylindrical spout 30 having a lower edge peripheral, circumferential flange 31.
  • This flange 31 has In principle, the flange can be glued to such a package, which is the case in particular in so-called Brikverpackept consisting of multilayer packaging films, a cardboard layer, a - or multi-layer plastic and at least one barrier layer included.
  • the spout, and thus the entire, self-opening plastic closure also be welded, especially if the outermost layer of the packaging film is a plastic layer.
  • the self-opening plastic closure 1 is mounted on a tubular bag, which usually consists of a complex, multi-layered plastic film with a barrier layer, it goes without saying that in most cases only welding and hardly any sticking is possible here.
  • On the inside of the cylindrical spout 30 can be seen an axially extending guide rib 34. This axial guide rib extends from approximately the upper edge of the cylindrical spout 30 to the lower edge of the spout 30.
  • This axial guide rib 34 serves to secure axial guidance of the cutting member to be described
  • a plurality of latching cams 35 are arranged on the inner wall of the cylindrical spout 30 in the lower region relatively close to the plane defining the peripheral flange 31, a plurality of latching cams 35 are arranged. Indeed there are practically two directly superimposed locking cams 35. These serve to hold the cutting member in a defined lowermost position.
  • a plurality of separate predetermined breaking point bridge parts 36 can also be seen on the inner wall of the cylindrical spout 30 in the upper quarter. This will also be returned later.
  • the attached on the outside of the cylindrical spout 30 stop ribs 37 which extend down to the peripheral flange 31, serve to cooperate with the guarantee strip.
  • a notch formed in the outer periphery of the flange 31 which forms an orientation notch 38 which serves only to orient the various parts in an assembling plant.
  • the cutting member is shown by itself in perspective view. It has a cylinder wall 40, whose upper edge is designed as a ramp-shaped end wall 41.
  • the ramp-shaped end wall 41 has a sliding surface 42 which rests in the assembled state of the self-opening plastic closure 1 on the sliding surface 25 of the first ramp-shaped annular wall 24.
  • a plurality of perforating teeth 43 are integrally formed on this edge.
  • Each perforating tooth 43 becomes bounded by Perforierkanten 44 and together include an acute angle.
  • Cutting edges 45 follow on both sides of these perforating edges 44. Two cutting edges 45 each directed to the same perforating tooth 43 together enclose an obtuse angle.
  • reinforcing ribs 491 are formed, which extend from a peripheral collar 47 to as close as possible to the tip of the respective perforating tooth 43.
  • the circumferential collar 47 extends in a plane perpendicular to the central axis of the cutting member.
  • the upper edge of the circumferential collar 47 is arranged at the height of the lowest point of the ramp-shaped end wall or the sliding surface 42.
  • the circumferential collar 47 has a guide recess 49.
  • several separate predetermined breaking bridges 48 the cutting member 4 with the spout before mounting 3 connects. Before assembly, these separate predetermined breaking point bridges 48 are connected to the separate predetermined breaking point bridges 36.
  • the cutting member 4 and the spout 3 together form a one-piece unit 70, which in the FIGS. 8 and 9 each shown in perspective view with different angles.
  • the aforementioned orientation notch 38 in the flange 31 of the spout part 3 is not least of importance because the spout part 3 and the cutting member 4 are preferably made as a one-piece structural unit 70. This reduces the cost of production and assembly.
  • the one-piece assembly 70 is realized so that the cutting member 4 is completely within the spout 30 of the spout 3. In this position, the highest point of the ramp-shaped end wall 41 of the cutting member 4 is at least approximately in the plane which is spanned by the upper edge 39 of the cylindrical spout 30.
  • the screw cap 2 is now placed on the one-piece assembly 70 with the screw cap is aligned so that the highest point 493 of the ramp-shaped end wall 41 is at that point corresponds to the point corresponding to the point on the first ramp-shaped annular wall 24 of the screw cap. 2 the top surface 21 is closest.
  • the predetermined breaking point bridges between the circumferential collar 47 and the inner wall of the spout 30 are now preferably separated at the last moment of pushing together so that only the separate predetermined breaking point bridges 36 and 48 are present.
  • the cutting member 4 is moved slightly axially downward so that the point of the cutting member 4 which is in the axial direction, namely the tips of the perforating teeth 43, is still above the plane defining the underside of the flange 31. This ensures that not already during welding of the assembled self-opening plastic closure 1 this does not rest on the packaging film of the container on which it is to be attached.
  • This position is now in the FIG. 10 shown in a diametrical section. This position shows the inventive self-opening plastic closure 1 in the mounted position before the first opening.
  • the predetermined breaking points between the screw cap 2 and the thereto Molded guarantee strip 22 are still intact, but since the diametrical section does not pass through a predetermined breaking point bridge this is not visible in the figure.
  • the first feed mechanism 50 In this position, the first feed mechanism 50 is in its home position.
  • This first feed mechanism 50 consists, as mentioned, of the first ramp-shaped annular wall 24 with its sliding surface 25, wherein the sliding surface 25 rests on the sliding surface 42 of the annular end wall 41 of the cutting member 40 over the entire circumference.
  • this second delivery mechanism 60 takes over its function.
  • this second feed mechanism 60 consisting of the external thread 27 at the second annular wall 26 with the internal thread 492 on the cylinder wall 40 of the cutting member 4 in engagement.
  • the first delivery mechanism 50 as in the FIG. 10 described the cutting member 4 already moved as far down in the direction of the flange 31 that the perforating teeth 43 are below the plane spanned by the flange.
  • the perforating teeth 43 have already perforated this sealing film.
  • the cutting member 4 is moved further in the direction of the flange 31 and not only the perforating tooth with its Perforierkanten 44, but also the adjacent cutting edges 45 as well as the Umfaltkante 46 are now below the of circumferential flange spanned plane and the packaging on which the self-opening plastic closure 1 according to the invention is mounted, is now completely cut and only in the region of Umfaltkante 46 still connected to the package.
  • the cut-open packaging film is folded over outside the region of the spout 30. In the position shown, both the internal thread 23 with the external thread 33 of the spout in combination, as well as the external thread 27 on the second annular wall 26 with the internal thread 492 of the cutting member 4 is still engaged.
  • first Annular wall may be designed as a normal cylindrical annular wall and be provided with corresponding threads, while then the second annular wall is designed as a ramp-shaped annular wall. This second annular wall would then have to interact with the ramp-shaped end wall of the cutting member.
  • both the first and the second feed mechanism both threaded or both with Zustellrampen. These need only be arranged in height so that both Zustellmechanismen can not be engaged simultaneously.
  • first feed mechanism 50 may be configured, instead of as shown, over 360 °, also only of two ramp-shaped sections extending over 180 °. This leads to a symmetrical power transmission, but then the ratio of delivery path per Rotation increases, as well as the required effort in the Clearö Maschinen.
