Definitions

  • the invention relates to a pouring element for a composite package comprising a main body with a hollow cylindrical spout and a flange arranged at an axial end of the spout; a hollow cylindrical cutting element, guided in a movable manner in the spout, with at least one cutting tooth for opening the composite package; and a reclosable screw cap, which, when the composite package is initially opened, serves to drive the cutting element; wherein the main body, the spout, the cutting element, and the screw cap are arranged concentrically about a vertical axis and wherein the outer hollow cylinder wall of the cutting element has a screw thread, which serves as a movable guide in the spout as well as a package with a pouring element of this type.
  • pouring elements applied to drink packages are integrated as part of the gable of the composite package for simplified handling during pouring and the possibility of resealing composite packages.
  • This type of pouring element is shown, for example, in EP 1 795 456 A1 or WO 2022/189028 A1 .
  • the hollow cylindrical cutting element opens the previously gas-tight composite package for the first time, thus forming a pouring opening, wherein the screw cap enables the now open composite package to be resealed.
  • the cutting element which is movably guided in the spout, is provided with force transmission elements and is thereby driven by corresponding force transmission elements on the screw cap.
  • the cutting element approaches the region of the composite package to be opened and after the first contact of the two elements, the at least one cutting tooth of the cutting element separates the composite package in the region of a weakening zone.
  • the movement path that the at least one cutting element travels is towards the weakening zone.
  • the opening process can be divided into the following stages, for example.
  • the approach of the cutting element mentioned above can also be omitted if the two elements already touch in the assembled state.
  • the cutting element then moves through the package material and separates it with the cutting teeth along a cutting line.
  • This separation process is a combination of separation, plastic deformation and material displacement, wherein a uniform and controlled application of the forces is advantageous.
  • the cutting element starts to fold the freely cut composite material or a closure part (as part of the main body) to the side and thus clear the spout for pouring the content. Folding away is carried out with the aid of the remaining piece of the weakening zone, which has not been separated.
  • This piece acts as a pivot axis, wherein first the cutting tooth and then the outer side of the cutting element exert force on the freely cut part while folding away and thus press it to the side.
  • the piece of composite material or the closure part is approximately parallel to the spout's central axis and along the outer wall of the screwed-in cutting element. This reliably enables pouring of the product contained in the composite package.
  • pouring elements with such a closure part are mainly, but not exclusively, used in aseptic packages.
  • previously sterilised foodstuffs are packaged under aseptic conditions in similarly sterilised packaging materials in order then to obtain so-called aseptic packages.
  • aseptic packages Apart from the question of aseptics, there are various types of composite packages into which a pouring element according to the invention can be integrated.
  • the pouring element is an integral part of the composite package, which is introduced during the manufacturing process of the same.
  • cut-outs of composite material which are initially shaped into package sleeves by sealing the longitudinal seam, are usually firstly connected to the pouring element in a so-called "form fill and seal" packaging machine (FFS).
  • FFS form fill and seal packaging machine
  • the first step can be provided in different ways:
  • the flange can be connected to one side of the package sleeve by a further plastic element, which is injection-moulded directly in the packaging machine.
  • the flange can also be welded directly to the package sleeve or glued to it without using an additional plastic element.
  • an initially completely sealed composite package is manufactured, wherein a punched hole is present in the composite package, usually in the gable region, into which a pouring element is introduced.
  • the pouring element is usually inserted by welding the flange to at least one layer of the composite material. Alternatively, these parts can also be glued together.
  • This second type of composite package is also characterised in that the insertion of the pouring element can be independent of the manufacture of the composite package.
  • the manufacture of the hole and also the insertion of the pouring element can therefore take place in each case before, during or after the manufacture of the composite package itself. Both steps are preferred before manufacture in order not to make the packaging machines themselves unnecessarily complicated.
  • This arrangement of the production steps also represents the simplest possibility of inserting the pouring element into the punched hole from the inside.
  • OCH OverCoated Hole
  • the punched hole is coated on one or both sides with polymer and the barrier layer before folding and manufacturing of the package sleeve, resulting in the package being sealed in a gas-tight manner again in the area of the hole.
  • the weakening zone is formed by these layers, wherein the cutting on the first opening of a package of this type takes place close to the edge of the overcoated hole.
  • Composite packages of this type are normally produced in one of two types of packaging machines.
  • an endless web of sterilised composite material is shaped into a tube and sealed longitudinally. After sealing it is filled with the similarly sterilised product and then sealed and cut at equal distances transversely thereto.
  • the resulting "package pillows" are then formed along the pre-folded edges into parallelepipedic packages.
  • the sealing seam formed during transverse sealing in the gable region is usually referred to as a gable seam.
  • the second alternative uses cut-outs of composite material, which are first shaped into package sleeves by sealing the longitudinal seam and then shaped on mandrels into package bodies open on one side, then sterilised, filled and lastly sealed and finally shaped.
  • the gable region can be designed differently, such as for example as a parallel surface to the base surface (flat gable package), as a surface formed at least partially at an angle to the base surface (oblique gable package) or also as a saddle roof with two opposing, oblique surfaces ('gable top' package). It is also possible to design the gable as a truncated pyramid.
  • the flange of the pouring element is square and has sealing surfaces running downwards in a truncated pyramidal shape at the edges. These are sealed with the composite material of the package, wherein four protruding ears are created, which are then folded over on the gable sides and sealed thereon.
  • the precise layer structure of the composite material can vary depending on requirements, but at least consists of a carrier layer of cardboard (liquid packaging board) and cover layers of polymer.
  • a barrier layer for example, aluminium (Al), polyamide (PA) or ethylene vinyl alcohol copolymer (EVOH) may be necessary to ensure an increased barrier effect for aseptic products against gases, in particular oxygen, and also against light in the case of aluminium.
  • composite packages of this type are also referred to as cardboard/polymer composite packages. If the pouring element is integrated as part of the composite package, it should have a similarly strong barrier effect against gases and light as the composite material used. At the same time, cheap materials should of course be used that are easy to recycle together. This also applies in particular to the materials of the pouring elements used.
  • the pouring elements explained in more detail above thus generally consist of three individual elements, namely the main body, the cutting element and the screw cap.
  • the cutting element is introduced into the main body from above and inserted into it until the upper edge of the spout of the main body and the upper edge of the cutting element run roughly in one plane.
  • the cutting element is either screwed in or pressed in linearly.
  • the screw cap is then pressed from above onto the main body in a predetermined orientation, wherein the screw cap is widened to be able to be moved over the external thread of the hollow cylindrical spout.
  • a generic pouring element with all features of the generic term of claim 1 is known from WO 2022/189028 A1 .
  • This document describes in detail the installation of the screw cap on the element already pre-assembled there, consisting of the main body and cutting element. Said assembly of main body and cutting element however causes large forces since one element is pressed into the other in an axial linear motion. This motion can also cause abrasion of the polymer material, especially of the threads. These abraded particles could potentially end up in the poured product.
  • the object underlying the present invention is to design and further develop the pouring element mentioned at the outset and previously described in more detail such that the forces necessary to assemble the cutting element and main body can be decreased. Furthermore, the force for assembly shall be reduced to prevent possible damage to parts due to high forces. Nevertheless, a good thread overlap for the opening process should be ensured as far as possible. This is particularly important in the lowest part of the spout in order to provide the cutting element with a good grip during the entire opening process.
  • the inner hollow cylinder wall of the spout has at least one internal thread having a lower thread section and an upper thread section, wherein the upper thread section of the internal thread has a reduced average thread height, measured radially, compared to the lower thread section and in that the lower thread section of the internal thread spans half a turn of helix rotation of the at least one internal thread on the axial end of the spout where the flange is arranged.
  • the internal thread has a reduced thread height in an insertion zone where the screw thread is located in the initial position of the cutting element before the composite package is initially opened.
  • the screw thread comprises at least one additional thread segment located in the region of the at least one cutting tooth.
  • the screw thread and internal thread have a high enough thread overlap after only a short rotation of the screw cap and, therefore, the cutting element.
  • the internal thread bordering the insertion area in the direction of opening (below and along the helix) has the same thread height as in the lower thread section.
  • the regions of the cutting element circumferentially outside of where the at least one cutting tooth is located form flexible regions, in which the screw thread is designed at least partially with thinner threads and/or threads with reduced heights.
  • the screw thread has fewer overlapping thread turns in the flexible regions of the cutting element than the maximum number of overlapping thread turns of the internal thread executed on the cutting element. This increases the flexibility of the cutting element generally and thus allows an easier application with lower forces.
  • the threads of the lower thread section are fully formed with a constant thread height along their helix length. This does not necessarily apply for the end sections of said lower thread section as these typically taper off. The rest of the lower thread section however should have no interruptions or segments with reduced thread height.
  • the average thread height of the upper thread section is less than 80%, preferably less than 60%, of the average thread height of the lower thread section. This can be achieved with either certain areas having a substantially reduced thread height as is described in other parts of the description in more detail or by simply reducing the thread height uniformly in the upper thread section.
  • the thread height of the internal thread in said zones is less than 70% of the average thread height of the lower thread section.
  • both the average thread height of the lower thread section and the thread height of the screw thread span more than 75% of the difference between the radii of the inner hollow cylinder wall of the spout and the outer hollow cylinder wall of cutting element. This guarantees a good overlap of the complementary threads with little room for radial movement in the most critical part of the opening process.
  • the thread width of the at least one internal thread is constant along the thread irrespective of any changes in thread height. Keeping the base constant along the thread helix allows for smoother movement of the cutting element, without gaps or introducing the possibility for additional axial movement. At the same time, it is still possible to profit from the reduced thread height while keeping the base width constant which leads to a more trapezoidal thread shape in these areas.
  • the height of the upper internal thread starts in the outermost third of the hollow cylindrical spout, viewed along the vertical axis, decreases steadily towards the pouring opening, preferably the spout also being funnel-shaped above the at least one internal thread.
  • the height of the thread turns preferably decreases steadily in the outermost third of the hollow cylindrical spout, seen along the vertical axis, at least in sections in the angle sections in which the assembly aids are arranged in assembled condition. This helps to center the cutting element during assembly, particularly when the cutting teeth are slightly deformed towards the outside. Such deformed cutting teeth could lead to an undesired wedging of the cutting element during the assembly process.
  • the outer thread and the internal thread comprise more than one, preferably four, thread starts. Such a design allows steeper threads and, therefore, a quicker vertical movement of the cutting element during the initial opening process.
  • the lower thread section is further stabilized by vertical webs located on the outside of the hollow cylindrical spout. These are located in the equivalent area to the lower thread section, simply on the outside of the spout. This way the vertical webs increase the stiffness of the spout exactly where the highest forces from the cutting element and opening process occur.
  • the upper thread section of the spout can also comprise a safety element located in a region of the spout remote from the flange to mechanically hold the cutting element in place before and during assembly.
  • the main body has a closure part with a central region and comprises an annular weakening zone which connects to the spout.
  • a closure part with a central region and comprises an annular weakening zone which connects to the spout.
  • the invention further relates to a package, in particular a cardboard/plastic composite package, with a pouring element applied to it according to any one of claims 1 to 14.
  • FIG. 1 shows a pouring element 1 in a fully assembled and closed condition with a vertical axis VA without a composite package.
  • a reclosable screw cap 2 which is used for the first opening and for reclosing of the composite package, is located on a main body 3, of which only a circumferential flange 4 is visible in Fig. 1 , which is used for connection with and integration into the composite package (not shown).
  • a VIIB-VIIB section line is also shown, which is discussed in more detail below.
  • the screw cap 2 has, in addition to the actual cover element 12, an underlying anchor ring 13 and in turn a ring 14 arranged underneath.
  • the cover element 12 is connected to the anchor ring 13 via a one-piece Tether T, i. e. a "retaining strap".
  • the screw cap 2 is provided with at least one slot S by means of a circumferential slit blade.
  • two slots S are present, as is visible from Fig. 1 . To produce them, two cuts are made in parallel planes.
  • the screw cap 2 is connected via a tether T, wherein both tether arms are connected to the anchor ring 13 in one piece.
  • a tether T wherein both tether arms are connected to the anchor ring 13 in one piece.
  • the slot runs over the circumference at least partially in a helix shape such that the two ends of this slot are at different heights relative to the vertical axis VA.
  • a design without a tether is also possible, only with a cover element 12 and with a ring 14.
  • the main body 3 of the pouring element 1 according to the invention which is partially concealed in Figures 1 and 2 by the screw cap 2, is shown individually in Fig. 3A in a perspective view from above. It comprises a horizontal flange 4, the outer edge of which is to be sealed with the package edge of a punched opening in a composite package (not shown), as described in more detail below. It also comprises a hollow cylindrical spout 5, which has an external thread 6 and an internal thread 7.
  • the internal thread 7 has a lower thread section 7A and an upper thread section 7B, wherein the lower thread section 7A is a fully formed thread with a full thread height and which spans a half turn of helix rotation of the internal thread 7, wherein the upper thread section 7B is flattened towards the pouring opening of the spout 5. Moreover, in the illustrated embodiment, the internal thread 7 is made from four single parallel threads.
  • the spout 5 has a plurality of vertical guide ribs 9 arranged on its outer circumference distributed over the circumference below the outer thread 6.
  • the depth of the vertical guide ribs 9 corresponds approximately to the height of the external thread 6.
  • the upper edges of all lateral guide surfaces of the vertical guide ribs 9 lie in a plane and ensure during the assembly process that the screw cap 2 is evenly widened and centred during the assembly process after having passed the external thread 6 of the spout 5.
  • a circumferential web 10A can be found in the region of these guide ribs 9, which is not designed to be rotationally symmetrical, but instead has recesses in some regions.
  • web sections 10B can also be seen which have the same outer contour as the circumferential web 10A.
  • the guide ribs 9 or the circumferential webs 10A and web sections 10B also ensure a stiffening of the spout 5 on the side of the closure part 19. This stiffening results in a more stable guidance of the cutting element 8 during the opening process.
  • a plurality of vertical webs 11 can be seen below the vertical guide ribs 9 and in extension thereto as well as below the webs 10B. These vertical webs 11 serve as both locking elements on the outside and reinforcing elements for the internal thread 7.
  • Fig. 3B shows the main body 3 shown in Fig. 3A in a vertical section along the line IIIB-IIIB from Fig. 3A with a partial enlargement of the section of the left cylinder wall of the spout 5. Due to the different heights of threads 7A and 7B, shown as thread heights THA and THB, the respective inner diameter DA of the lower thread section 7A is smaller than the inner diameter DB of the upper thread section 7B with the flattened top, as can be more clearly seen from the enlarged portion.
  • the main body 3 has a closure part 19 with a central region 20 and comprises an annular weakening zone 21 which connects to the spout 5 and a conical annular intermediate region 22 which extends between the weakening zone 21 and the central region 20 of the base of the main body 3 and which jointly seal the pouring opening.
  • the chamfering of the intermediate region 22 compensates for the thickness difference between the central region 20 and the weakening zone 21.
  • the internal thread 7 serves to accommodate a cutting element 8, which, however, is only shown starting in Figures 5A and 5B and is also described in more detail further below.
  • Fig. 3C shows a similar view as in Fig. 3B , wherein the cutting line the line IIIC-IIIC from Fig. 3A is turned clockwise about an angle of 50° compared to the line IIIB-IIIB shown in Fig. 3A .
  • the internal thread 7 has a reduced thread height 7B in areas where the screw thread is located in the initial position of the cutting element 8 before the composite package is initially opened (insertion zone). The transition sections from the insertion zone with a reduced thread height 7B to the adjacent sections with fully formed thread height 7A are more clearly visible in this orientation.
  • the insertion zone is arranged in the region of the upper thread 7B, which is clearly shown with the curly bracket right of Fig. 3C . Moreover, the position of the external thread 25 of the cutting element 8 (not shown here) is indicated with a dot pattern.
  • Fig. 4 shows a vertical section through the screw cap 2 of the pouring element 1 according to the invention, wherein the cover element 12, the anchor ring 13 and the ring 14 of the screw cap 2 are clearly shown. Two of a total of three force transmission elements 15, which extend downwards from the cover element 12, are also particularly clearly visible. Furthermore, an internal thread 16 can be recognised inside the cover element 12, which corresponds to the external thread 6 of the spout 5 of the main body 3. In addition, Fig. 4 shows that the anchor ring 13 has a circumferential retaining web 17 in its lower region. This is described in more detail below.
  • Fig. 4 clearly shows that the ring 14 serving as a tamper-proof seal has on its inside a plurality of stop elements 18 arranged distributed over the circumference.
  • the arrangement of the stop elements 18 is selected such that they lie in the assembled state of the pouring element 1 in the region of the vertical webs 11 as depicted in Fig. 3A .
  • Aforementioned recesses in the circumferential webs 10A and 10B also align with these stop elements 18 to facilitate assembly.
  • the stop elements 18 engage with the vertical webs 11 when the screw cap 2 is opened for the first time, so that a rotation of the circumferential ring 14 is reliably excluded.
  • the vertical webs 11 are arranged in such a way that they, as can be seen clearly in Fig.
  • the anchor ring 13 and ring 14 are connected to one another in a single piece via small material bridges. During the initial opening process, these material bridges break up due to the blocking catching of the circumferential ring 14 and thus signal to the consumer that the pouring element 1 has already been opened. A tamper-proof seal formed in this way is also known as a Tamper Evident element.
  • Fig. 5A shows a cutting element 8 individually in a perspective view.
  • the hollow cylindrical structure of the cutting element 8 can first be seen, wherein three force accepting elements 24 evenly distributed over the circumference can be seen inside the cutting element 8, which are driven when the pouring element 1 applied to a composite package is opened initially.
  • the drive is performed by the screw cap 2 (not shown here), which thereby causes the rotation of the cutting element 8 by means of force transmission elements 15, as described in more detail below.
  • Fig. 5A clearly shows that the cutting element 8, which is represented and thus preferred, has a screw thread 25 on its outer side.
  • the screw thread 25 comprises the same number of single parallel thread sections as the internal thread 7 of the spout 5 (without individual numerals).
  • the cutting element 8 from Fig. 5A is also shown in Fig. 5B in a vertical section along the line VB-VB in Fig. 5A . It is clearly discernible that between the two regions of the cutting element 8 arranged on the right and left, on which two assembly aids M1 and M2 are located at the top, a region is created which is marked with a dot pattern for better explanation, and which can serve as a flexible region F due to its significantly lower height. Outside this flexible region, the cutting element 8 is designed to be more than twice as high and also has two cutting teeth 23 in its lower region, which cannot be identified in the perspective view of Fig. 5A .
  • the front region of the cutting element 8 from Fig. 5A also has a flexible region F: A region of significantly reduced height of the cutting element 8 between the internally arranged force accepting element 24 and the end of the reinforcement web for the cutting tooth 23 (not specified in more detail) in the bottom left in Fig. 5A .
  • the assembly of the main body 3 and the cutting element 8 for the pouring element 1 according to the invention is carried out by means of the following steps:
  • FIGS 6A and 6B illustrate the assembly of the main body 3 and the cutting element 8 in more detail.
  • Fig. 6A initially shows the start of assembly with the cutting element 8 just inserted partially.
  • Fig. 6B shows the further assembly process of the cutting element 8 in the main body 3.
  • the special embodiment of the upper edge of the cutting element 8 according to the invention can also clearly be seen in Fig. 6A .
  • two optional raised assembly aids M1 and M2 can be clearly seen on the right and left at the upper edge of the cutting element 8. Between these assembly aids M1 and M2, the cutting element 8 is designed flexibly and thus forms flexible regions F, of which only the rear flexible region can be seen here due to the sectional view.
  • the main body 3 sealed with the flange 4 at the circumferential edge of an opening in a composite package (not shown) further has a closure part 19 formed in the spout 5 in the plane of the flange 4.
  • the closure part 19 has a central region 20 and comprises an annular weakening zone 21 which connects to the spout 5 and a conical annular intermediate region 22 which extends between the weakening zone 21 and the central region 20 of the base of the main body 3 and which jointly seal the subsequent pouring opening.
  • the cutting element 8 in the represented and in this respect preferred embodiment has two cutting teeth 23 on its underside, which are each arranged in the region below the assembly aids M1 and M2 as can be clearly seen in Fig. 6B .
  • the hollow cylindrical cutting element 8 On its outer circumference, the hollow cylindrical cutting element 8 has a screw thread 25, which obviously hampers pressing the cutting element 8 axially into the main body 3.
  • the screw cap 2 is first aligned rotationally on the unit consisting of the main body 3 and cutting element 8 and then placed near the closure part so that the force transmission elements 15 of the cover element are arranged next to the force accepting elements 24.
  • Fig. 7A the position of the screw cap 2 is shown with reference to the main body 3 and the opening means completely inserted therein.
  • the internal thread 16 of the cover element 12 is still arranged above the main body 3 and cutting element 8.
  • On the left side of Fig. 7A it is visible how the retaining web 17 of the anchor ring just passes the uppermost thread of the external thread 6 of the spout 5 and how the stop element 18 of the ring 14 has already passed the external thread 6.
  • the inner diameter of the circumferential retaining web 17 of the anchor ring 13 is slightly smaller than the outer diameter of the circumferential web 10A.
  • a brief deformation of both elements is possible due to the plastic material used, wherein the circumferential retaining web 17 is widened. However, this expansion does not occur evenly over the circumference of the retaining web 17 due to the recesses present in the web 10A.
  • Fig. 7B shows the pouring element 1 in its fully assembled position.
  • the hollow cylindrical cutting element 8 with its cutting teeth 23 is arranged inside the main body 3, which, when the pouring element 1 and thus the composite package P is initially opened, separates the closure part 20 by destroying a partial section of the weakening zone 21.
  • the vertical axis VA (shown only in Fig. 1 ) is defined by the concentrically arranged hollow cylindrical elements of the spout 5 and the cutting element 8.
  • the cutting element 8 rotates helically about the vertical axis VA during the opening process and moves along this axis.
  • This helical movement is defined by a second thread pair 7 and 25, which is located between the inner side of the spout 5 and the cutting element 8 and ensures a positive guide of the cutting element 8 during its rotation.
  • the cutting element 8 is driven on at least one force accepting element 24 (not shown), which interacts with at least one corresponding force transmission element 15 of the screw cap 2.
