Definitions

  • the invention relates to a pouring element for a pack for receiving flowable or pourable products, in particular a carton having a pouring channel, wherein the pouring channel has channel cross sections with substantially identical cross sectional areas arranged perpendicular to its center line, wherein the outer channel cross sections of the pouring channel a product inlet opening and a substantially circular product outlet opening are and wherein the product inlet opening is associated with a flange for connection to the pack and a method for applying a pouring element having a flange on an opening having a package, preferably Flachgiebelpackung, for receiving flowable products.
  • Such pouring elements are used in particular in gable packaging.
  • These include also flat gable composite packages, which have long been known and are very often used for packaging of liquid foods such as milk, juice and the like.
  • flat gable composite packages are cuboid and have a folded gable seam, which extends over the top of the package and is fastened by its ends to two opposite lateral surfaces of the pack.
  • gable packs there are other types of gable packs.
  • One type also consists of a composite material and has an upright in the upright position of the pack gable with two mutually inclined by the gable seam separate gable sections ("slanted gables") on.
  • the pouring element has a pouring channel which tapers slightly, but otherwise has substantially identical cross-sectional areas arranged perpendicular to its center line.
  • the outer channel cross sections of the pouring element form a product inlet opening and a substantially circular product outlet opening, wherein the product inlet opening is assigned a flange for connection to the package.
  • the DE 24 17 387 A1 discloses a pouring device for a container composed of two half-shells, wherein the casting device is inserted between the half-shells formed as sheet metal or plate body and secured thereto.
  • the pouring device in addition to an opening neck with a cylindrical cross-section container side mounting member having a boat-shaped cross section, wherein the free cross section of the opening neck for flowing with flowable or pourable product is much smaller than the free cross section of the attachment member.
  • the pouring properties of the known pouring device are thereby limited.
  • a pouring member having a cylindrical cross section is made of US 4,909,434 is known, which has two flanges at its pack-side end, so that the pouring element can be sealed to both the inside and the outside of the pack.
  • the from the WO 03/030695 A1 known lid of a drinking cup for children includes a pouring element, which is made in one piece with the lid.
  • the free channel cross sections of the pouring element taper from the product inlet opening to the product outlet opening, which is given only in the form of a plurality of small holes. This is to prevent leakage from the product, provided that there is no negative pressure by suction on the pouring element.
  • a pouring element for a cardboard carton with an inner bag disposed therein is for example in the DE 4 026 562 A1 described.
  • the pouring element is welded to the inner bag, which in turn is glued to the pack from the inside.
  • the pouring channel of the known pouring element tapers from the product inlet opening to the product outlet opening.
  • a disadvantage of the generic pouring element is that, given a right-angled gable section, the maximum diameter of the pouring channel is determined by the length of the shorter sides of the gable section and the minimum required width of the flange. Thus, only relatively narrow pouring channels can be realized in which the pouring speed is reduced and the pouring is difficult. This applies in particular when using flat gable packages, since obliquely arranged gable sections have a larger area for the application of pouring elements.
  • the gable section and thus the permissible diameter can be increased by displacing the gable seam to one side of the jacket.
  • this must be "bought" by a significantly increased manufacturing costs in the production of the package itself.
  • the dimensions of a gable section are hardly selectable but essentially fixed by the requirements in terms of capacity, stability and stackability.
  • a pouring element must also be able to be produced without problems and at low cost. This additionally limits the design options with regard to the pouring elements.
  • the diameter of the product outlet opening can easily correspond to the length of the shorter sides of the gable section, without the product inlet opening having to have a significantly smaller cross-sectional area than the product outlet opening. It is even possible that the diameter of the product outlet opening is greater than the length of the shorter sides of the gable section, if a projection of the product outlet opening is realized on the gable seam.
  • the cross-sectional area of the product inlet opening can of course also be significantly larger than the cross-sectional area of the product outlet opening. It is only essential that the product outlet opening can be selected larger, without the product inlet opening representing a bottleneck and limiting the product stream flowing through the pouring channel. It also goes without saying that in the case of pouring elements with larger product inlet openings compared to the product outlet openings, the product outlet openings represent the limiting bottleneck. Consequently, it is possible but less preferable to make the product inlet opening significantly larger than the product outlet opening.
  • the size of the product outlet opening is not limited in many areas by the departure from consistently cylindrical pouring channels, so that you will run in the rule, the product and the product outlet opening in about the same size.
  • the absolute size depends on the required or the possible for a given gable section.
  • the product inlet opening is oval or rectangular with rounded corners.
  • the pouring element whose channel has a non-rotationally symmetrical, elongated product inlet opening and a round product outlet opening, can not or only with considerable effort in the Applizierform finished.
  • the pouring element can be brought from a production mold into an application mold. In this way, the pouring element can be transferred into an applicator mold after production. Only in this Applizierform the advantageous embodiments of the pouring come into play.
  • the manufacturing form is characterized in that the pouring element can be easily produced in this form. In particular, with this form, a tool can be easily removed from the casting channel after the production of the pouring element.
  • the pouring channel is formed substantially cylindrical in the manufacturing mold. This makes it possible to produce the pouring element, for example, by injection molding or the like, since then a part of a mold or a tool forming the negative of the pouring channel after the injection molding or the like can be readily removed from the then cylindrical pouring channel. It is understood that all approximately cylindrical, konische.oder comparable shapes for the pouring are conceivable, as long as the possibility of demolding exists.
  • the edge of the flange in the manufacturing mold at least with respect to two on opposite sides of the product inlet opening, instead of pointing radially outward, in the direction of the product outlet opening stand out.
  • this means that the flange is virtually bent or folded over from a plane perpendicular to the center line in the direction of the product outlet opening.
  • the flange can also protrude in principle in the direction away from the product outlet side direction, in which case, however, a whot compact pouring element is obtained in the manufacturing form.
  • two further regions of the flange exist in the production form, wherein the flange there in the opposite direction, ie in the direction of Product entry side protrudes outwards. This is almost inevitably so in a preferred embodiment, wherein the flange is uniformly shaped in the Applizierform and has a constant thickness. Basically, however, there are certain constructive leeway in determining the manufacturing form of the pouring element.
  • the flange extends in a plane which is preferably perpendicular to the center line of the pouring channel.
  • the flange and the adjoining portion of the packing can be made as two parallel layers bonded together with high bonding forces.
  • the pouring element in the applicator mold has a product-inlet-side section, in which the channel cross-sections are more similar to a circle, the farther they are from the product inlet opening.
  • the Products inlet-side portion provided a pouring channel, which, preferably starting in an outflow direction, preferably gradually approaches a cylindrical channel, starting with the product inlet opening. This, preferably uniform, transition from a non-round, preferably oval, to a round channel cross section ultimately allows low pressure losses and a uniform flow.
  • the product outlet side section is cylindrical. Ultimately, therefore, the pouring channel does not run over its entire longitudinal extent towards a circular product outlet opening. Thus, the pouring element can be easily provided with a screw cap or the like on the product outlet side section.
  • the area which is available for a pouring element for the pouring element can be utilized particularly expediently if, in the applicator mold, the outer edge of the flange is at least as far from the center line as at least at two points opposite to one another product outlet opening.
  • the aforementioned straight line is parallel to the shorter side of a rectangular gable section, it can be achieved that the space available in that direction is exploited by both the flange and the product outlet opening.
  • the width of the product inlet opening and flange and the diameter of the product outlet opening ultimately correspond approximately to the length of the shorter sides of the gable section.
  • the pouring channel preferably the entire pouring element, to be elastic and to be brought into a shape in which the channel cross sections have a non-rotationally symmetrical, oblong shape. This ultimately makes it possible to compress the pouring element or at least its pouring channel and to guide it from an inner side of the pack or the packaging material through a prefabricated opening and subsequently to connect the flange to the pack.
  • the shape of the product inlet opening in the applicator mold and the shape of the opening approximately coincide.
  • such an elastic configuration of the pouring element can offer advantages both directly in the application mold when the pouring element is produced in the production mold and when the pouring element is produced.
  • both deformations can also be performed simultaneously, which can increase the production speed.
  • the production of a corresponding packing takes place as follows: feeding the packing to a device for forming the pouring element and casting the pouring element onto the opening.
  • the pouring element is cast directly on the opening. Compared with the production of the pouring element and the subsequent application of the same to a pack, a process step can ultimately be saved. It is particularly expedient if the casting of the pouring takes place immediately before the filling process.
  • the device for forming the pouring element can thus be integrated, for example, in the actual filling machine.
  • the casting takes place in such a way that the pouring element is connected to the pack at the same time, for example during a cooling and solidification process as it takes place during injection molding. This can ultimately be saved a further process step.
  • the above-mentioned method for applying a pouring element is characterized by the following steps: forming the pouring element in the production mold with a substantially cylindrical pouring channel and with a flange attaching at least one tool to the pouring element, bending the flange with the tool into an applicator mold a product inlet opening having a non-rotationally symmetrical elongated shape and a circular product outlet opening, wherein the pouring channel has channel cross sections arranged essentially perpendicular to its center line and having essentially identical cross sectional areas and connecting the flange to the package. It is understood in this context that the flange and the package are connected by gluing, welding or the like and forming the pouring member by injection molding or the like. By erfindungeadore method, it is possible to produce a pouring element with preferred pouring properties in a particularly simple manner.
  • pouring elements made of plastic, preferably a thermoplastic material such as PE, PP, PVC, PET, etc., have preferred properties.
  • the Fig. 1 to 4 show a pouring element 1 in Applizierform.
  • the pouring element 1 has a pouring channel 2 with a straight line extending between a product inlet opening 3 and a product outlet opening 4 center line 5.
  • the pouring element 1 is designed such that the product to be poured out of a pack first flows into the product inlet opening 3 and then flows through the pouring channel 2, in order ultimately to flow out of the product outlet opening 4.
  • the center line 5 can nevertheless run in a curved manner.
  • the product inlet opening 3 and the product outlet opening 4 are preferably of the same size have surface.
  • all the channel cross-sections running perpendicular to the center line 5 have an area which is identical to the area of the product inlet opening 3 or the product outlet opening 4. For a flow without cross-sectional widening or reduction in cross-section is possible, which is particularly favorable from a fluidic point of view.
  • Fig. 1 it can be seen that it is subdivided into a product-entry-side section 6 and a product-outlet-side section 7. It is such that substantially the product inlet opening 3 is surrounded by a flange 8, which protrudes in a plane perpendicular to the center line 5 to the outside. This makes it readily possible to connect the product outlet 4 facing away from the surface of the flange 8 with the pack, so that the product does not escape unintentionally or is contaminated from the outside.
  • the pouring channel 2 in the product inlet-side section 6 in the pouring direction with respect to the sectional plane III-III continuously tapers and continuously expanded with respect to the sectional plane IV-IV.
  • an external thread 9 is also provided, so that easily a not-shown screw can be screwed. This ultimately results in a reclosability of the pouring element 1.
  • the pouring channel 2 is formed substantially cylindrical in the production position. It is not necessary that a perfectly cylindrical shape is achieved .
  • the pouring channel 2 does not partially taper along the center line 5 in one direction and partially widened. Otherwise, a molding forming the negative of the pouring channel 1 can not readily be removed from the preferably injection-molded pouring channel 2 during production. However, although this may be structurally complicated, it is possible to make the mold in several parts. Thus, the individual parts can be joined together in a specific sequence to form a negative of the pouring channel 2 and removed after production from the pouring channel 2. Alternatively or additionally, it is conceivable that the individual parts are enlarged to form the mold and reduced again for removal from the pouring channel 2.
  • Fig. 7 is the Packungsgiebel a package 10 according to the invention with the pouring element 1 of the invention Fig. 1
  • the package 10 as such according to the invention is a flat gable composite package. Shown is ultimately a gable with two substantially parallel to each other arranged gable sections.
  • the gable section 12 shown in the foreground has a pouring element 1 and an in Fig. 8 closer opening 16 on. The shape and the area of the opening 16 are adapted to the product inlet opening 3.
  • the gable section 12 is formed rectangular, with two shorter sides 13 across a gable seam 11 and two longer sides 14 parallel to the gable seam 11.
  • a product outlet opening 4 can be provided with an area which is not possible with prior art packages.
  • the diameter of the product outlet opening 4 corresponds approximately to the length of the shorter sides 13.
  • the product outlet opening 4 it would be possible for the product outlet opening 4 to be significantly larger, as a result of which it ultimately protrudes beyond the gable seam 11. In such a case, it would be preferable that the product outlet opening 4 does not protrude beyond the shell sides of the package 10 in order to impair approximately the stackability of the package 10.
  • the flange 8 has parallel to the shorter sides 13 an extent corresponding to the length of the shorter sides 13 approximately. This ensures that the space available in the direction of the shorter sides 13 is utilized and the extension of the pouring element 1 in a direction parallel to the longer sides 14 can be minimally selected. This brings fluidic advantages, especially for products with lumpy proportions.
  • the flange 8 can in principle also be arranged on the inside of the pack 10, for which purpose, however, it must be guided through the opening 16, preferably from the inside.
  • Fig. 8A shows two process steps of a preferred, embodiment of a method according to the invention for applying the pouring element 1 on an opening 16.
  • the pouring element 1 is shown by the same direction as in den- Fig. 4 and 6 ,
  • the flange 8 of the pouring element 1 was set before attaching the tools 15 to the package 10, on the corresponding opening 16 in the package 10, which in turn rests against a support 17.
  • Die Auflage Chemistry 17 ist in der ⁇ réelle 10 in die ⁇ réelle 10 festble.
  • the pouring element 1 could also come into contact with the pack 10 just before it is connected to the pack 10 and previously be pressed directly against the support 17. If the pack 10 is stable enough or another type of abutment is provided, it is also possible to dispense with support 17.
  • Fig. 8B showing the bending of the flange 8
  • the tools 15 are tilted or pivoted about an axis not shown in detail in order to reach the end position, in which now the pouring element 1 is in Applizierform. It is not shown in detail that the tools 15 are formed at their engaging ends according to the Applizierform. While this is not required, it can be beneficial to the process. Furthermore, the number of tools 15 used is not fixed. Also, for example, a tool 15 may have a plurality of engagement elements for attachment to the pouring element 1.
  • the pouring element 1 can also be connected to the pack 10 with the side of the flange 8 facing the product inlet opening 4. In this case, the pouring element 1 is guided with the product outlet opening 4 forwards from the inside of the pack 10 through the opening 16.
  • the product outlet-side section 7 and possibly also the product-entry-side section 6 are elastic and can be brought into an oval shape in order to fit through the opening 16.
  • the pouring element 1 with the opposite surface of the flange 8 with the outside of the package 10. This may allow faster manufacture of the package 10 and may result in the saving of a process step. Then, the bending over of the flange 8 and the connection of the same to the packing 10 can optionally also be carried out essentially in one method step.
