Description

Pouring element for a pack for

Inclusion of flowable products and procedures for

Production of such a package

The invention relates to a Ausgießelernent for a package for receiving flowable or pourable products, in particular a pack gable cardboard / plastic composite package, with a pouring channel, wherein the pouring channel perpendicular to its center line arranged channel cross sections having substantially identical cross-sectional areas, 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 package. Furthermore, the invention relates to a package for receiving flowable or pourable products having a gable-suturing packing gable, preferably a flat gable, wherein the gable packing has a flat, preferably rectangular gable portion with a pouring element. Furthermore, the invention relates to a method for producing a package for receiving flowable or pourable products having a gable seam packing gable, preferably flat gable, the packing gable having a flat, preferably rectangular gable portion with a pouring element, and a method for applying a pouring element having a flange to an opening having a package, preferably flat gable, for receiving flowable products. Pouring the aforementioned type are already known from practice and cylindrical. This cylindrical configuration makes it possible in a simple manner to provide a resealable screw cap or the like at one end of the pouring element. The opposite end of the pouring element has an annular radially outwardly projecting flange. About this flange, the spout is fluid-tightly connected to the inside of the pack. To ensure a secure connection, it is necessary to provide a comparatively wide flange.

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. In general, 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.

In addition, there are other types of gable packs. One type also consists of a composite material and has an upwardly extending gable in the upright position of the pack with two mutually inclined by the gable seam separate gable sections ("slanted gables") on. From EP 1 088 770 A1 a generic pouring element for a beverage carton packaging is known, as it is usually used for milk, juices, etc. In this case, 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.

On the other hand, DE 24 17 387 A1 discloses a casting device for a container composed of two half-shells, wherein the casting device is inserted between the half-shells designed as sheet-metal or plate bodies and fastened thereto. For this purpose, 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.

Further, a pouring member having a cylindrical cross section is known from US 4,909,434 which has two flanges at its package end so that the pouring member can be sealed to both the inside and the outside of the package. The well known from WO 03/030695 Al 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 folding box made of cardboard with an inner bag arranged therein is described, for example, in DE 4 026 562 A1. 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.

In this context, it should be noted that in particular in flat gable composite packages by a shift of the gable seam to one side of the shell Although the gable section and thus the permissible diameter can be increased. However, this must be "bought" by a significantly increased manufacturing costs in the production of the package itself. Basically, the dimensions of a gable section are hardly freely selectable, but are essentially determined by the requirements in terms of capacity, stability and stackability. Furthermore, 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.

It is therefore an object of the present invention to design and refine a pouring element, a pack, a method for producing a pack and a method for applying a pouring element to a pack in such a way that improved pouring properties can be achieved without accepting a disproportionately large production outlay to have to.

This object is achieved with a pouring element of the type mentioned above and described in more detail in that the product inlet opening in the applicator has a non-rotationally symmetrical, elongated shape.

By means of the invention, it is possible to provide, for a given packing, a pouring element having a pouring channel which has a much larger cross-sectional area for the outflow of product from the packing than is the case in the prior art. Ultimately, the product can be easier and faster out of the pack flow out. If the pouring element is provided in a rectangular gable section, 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. It is ultimately the case that the surface of the corresponding gable section which is available for the pouring element can be utilized much better by the non-rotationally symmetrical, elongated design of the product inlet opening than is the case with pouring elements of the prior art.

Under the Applizierform is here understood the shape of the pouring element, in which the pouring element is connected to the pack. The Appliziertrom corresponds thus substantially the shape in which the pouring element is ultimately used.

In connection with this, it goes without saying that 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 essential only that the

Product outlet can be selected larger, without the product inlet opening represents a bottleneck and limits the flowing through the pouring product flow. It is further understood that with 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. Ultimately, 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 the product inlet and the product outlet opening in about the same size in the rule. The absolute size depends on the required or the possible for a given gable section.

By turning away from round product inlet openings whose special design can be optimally adapted with respect to the cross-sectional area to be achieved, the flowability and a simple production of the pouring element to the respective package shape or shape of the gable section, with almost any shaped product inlet openings are conceivable.

With regard to the design effort in the production and application of the pouring it makes sense that the product inlet opening is oval or rectangular with rounded corners.

Depending on which shape is selected for the design of the product inlet opening, it may be the case that 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. To counter this problem, it may be provided that the pouring element can be brought from a manufacturing mold into an Applizierform. 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. Here, 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.

In a particularly preferred embodiment of the pouring element according to the invention it is provided that 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 negative part of the pouring channel forming part of a mold or a tool after injection molding or the like can be easily removed from the then cylindrical pouring channel. It is understood that all approximately cylindrical, conical or comparable shapes for the pouring channel are conceivable here, as long as there is the possibility of demoulding.

In order to produce the pouring element in the manufacturing form particularly simple and then easily bring in the Applizierform, 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. In other words, this means that the flange is quasi from a plane perpendicular to Center line is bent or folded in the direction of the product outlet.

In this context, it is understood that the flange can in principle also protrude in the direction away from the product outlet side direction, in which case, however, a less compact pouring element is obtained in the manufacturing form. Furthermore, it is generally preferred if two further regions of the flange exist in the production mold, wherein the flange projects there in the opposite direction, ie, in the direction of the product inlet side to the outside. 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 constructional freedom in determining the production form of the pouring element.

It is particularly preferred, regardless of the exact configuration of the manufacturing and Applizierform, if automatically by bending the flange at least an approximately oval shape of the

Product entry opening is created. This means that the manufacturing and applicator molds are forcibly coupled to one another and preferably only these two molds are stable, while the pouring element in a different form tends to change into one of the two forms mentioned.

For secure, fluid-tight connection of the pouring element with the pack as such, it is advisable that extends in the Applizierform the flange in a plane which is preferably perpendicular to the center line of the Pouring channel is. Thus, the flange and the adjacent portion of the packing can be made as two parallel layers bonded together with high bonding forces.

From a fluid engineering point of view, it is particularly expedient if 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. In other words, a pouring channel is provided in the product inlet-side section, which gradually approaches a cylindrical channel, preferably beginning with the product inlet opening, in an outflow direction. 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.

In order to make the pouring element reclosable in the applicator mold, it makes sense that 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 surface 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 at least at two opposing points spaced approximately as far from the center line as the edge of the product outlet opening. This means in other words that the distance between two points on the edge of the flange, which are connected by a straight line intersecting the center line of the spout, is as large as the diameter of the product outlet opening. In the case where the aforesaid straight line is parallel to the shorter side of a rectangular gable section, it can be achieved that the space available in this direction is determined by both the flange and the flange

Product outlet is exploited. 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.

In order to be able to apply the pouring element without further ado, it can be preferred if the pouring channel, preferably the entire pouring element, is elastically formed and can 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 of the packaging material through a prefabricated opening and subsequently to connect the flange to the pack. In this case, it is preferable that the shape of the product inlet opening in the applicator mold and the shape of the opening approximately coincide. It goes without saying that such an elastic configuration of the pouring element has advantages both in the production of the pouring element in the production mold and in the production of the pouring element directly in the applicator mold can offer. In the first case, it is also possible to elastically deform the pouring element both in the applicator mold and in the production mold, depending on whether a preceding or a subsequent forming into the applicator mold is more favorable. Of course, both deformations can also be performed simultaneously, which can increase the production speed.

In the case of the packing mentioned in the introduction and described in detail above, the above-mentioned object is achieved in that the gable section has a non-rotationally symmetrical, elongate opening and the pouring element is connected to the gable section in a fluid-tight manner around the opening. This ensures that in the package according to the invention over the prior art improved pouring properties are achieved.

Also in connection with the opening, it may be favorable from a constructive point of view if the opening is substantially oval or rectangular with rounded corners.

The method for producing a package mentioned in the introduction is characterized according to the invention by the following steps: feeding the package to a device for forming the pouring element and casting the pouring element onto the opening.

It is therefore essential that 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. Especially useful it is when the pouring of the Ausgießelernents 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.

It is particularly expedient if 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.

In contrast, the method for applying a pouring element mentioned at the outset is characterized by the following steps: forming the pouring element in the production mold with a substantially cylindrical pouring channel, applying at least one tool to the pouring element, bending the flange with the tool into an applicator mold with a product inlet opening in a non-rotationally symmetrical elongated shape and connecting the flange to the packing. It is understood in this connection that the flange and the packing are connected by gluing, welding or the like and the forming of the pouring element can be carried out by injection molding or the like. By the method according to the invention it is possible to produce a pouring element with preferred pouring properties in a particularly simple manner.

Although in principle any materials can be used for the production of the pouring element, however, have pouring elements made of plastic, preferably a thermoplastic such as PE, PP, PVC, PET, etc., have preferred properties.

The invention will be explained in more detail below with reference to a drawing which only ever represents a preferred exemplary embodiment of the pouring element according to the invention, the pack according to the invention and the method according to the invention. In the drawing show:

Fig. 7 is a packing gable of an inventive

Pack with the pouring element of Fig. 1 in a perspective view and

Fig. 8 shows two steps of an inventive

Method in a schematic representation. Figs. 1 to 4 show a Ausgießelernent 1 in Applizierform. The Ausgießelernent 1 has a pouring channel 2 with a straight line between a product inlet opening 3 and a

Product outlet 4 extending center line 5 on. In this case, 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. Even if the design of the pouring element 1 with a rectilinear center line 5 is preferred from a constructive point of view, the center line 5 can nevertheless run in a curved manner. This can be achieved, for example, that the product inlet opening 3 and the product outlet opening 4 are not aligned concentrically with each other, so that the product outlet opening 4 can survive about a gable seam of a pack in the direction of an adjacent gable section.

It is essential to the pouring element 1 shown that the product inlet opening 3 and the product outlet opening 4 have a preferably equal area. In addition, 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. In the Ausgießelernent 1 shown in Fig. 1 it can be seen that this in a product-entry-side section 6 and a product outlet side section

7 is divided. It is such that substantially the product inlet opening 3 is surrounded by a flange 8 which projects in a plane perpendicular to the center line 5 to the outside. This makes it possible without further ado, the product outlet opening 4 facing away from the surface of the flange

8 to connect with the pack, so that the product does not escape accidentally or is contaminated from the outside.

In addition, it is so that 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 cutting plane IV-IV. This ultimately leads to the pouring channel 2 of an oval cross-sectional shape evenly merges into a cylindrical, product outlet side section 7. Here, 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.

As is apparent from FIGS. 5 and 6, the pouring channel 2 is formed substantially cylindrical in the production position. It is not necessary that a perfectly cylindrical shape is achieved. Ultimately, it is only important that 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 during manufacture can not readily be made of the preferably injection-molded article Pouring channel 2 are removed. 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 shows the packing gable of a packing 10 according to the invention with the pouring element 1 according to the invention from FIG. As such, the package 10 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 opening 16, which is designated in greater detail in FIG. 8. The shape and the area of the opening 16 are adapted to the product inlet opening 3.

It is essential that 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. In the preferred embodiment of the package 10 according to the invention, it is such that 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. In principle, it would be possible for the product outlet opening 4 to be significantly larger, as a result of which it ultimately reaches the gable seam 11 over projects. 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 so as not to affect the stackability of the package 10.

Also, 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.

It is understood, in particular with reference to FIG. 7, that 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. Schematically, Fig. 8A shows the attachment of two tools 15 from opposite sides of the flange 8. Here, the pouring element 1 of the same direction 4 and 6. The flange 8 of the pouring element 1 was placed on the packing 10 before fitting the tools 15 on the corresponding opening 16 in the pack 10, which in turn bears against a support 17. Basically, the Ausgießelernent 1 but only shortly before joining with the pack 10 come into contact with it and be pressed directly against the support 17. If the package 10 is stable enough or another type of abutment is provided, the support 17 can also be dispensed with.

From Fig. 8B, which shows the bending of the flange 8, it follows that the tools 15 are tilted or pivoted about an axis not shown in detail 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.

It goes without saying in this context that 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 ahead of the inside of the pack 10 through the opening 16. In this case, 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. In this connection, it is conceivable that the elastic deformation of the pouring channel 2 is caused by the tools 15 shown in FIGS. 8A and 8B while passing through, for example, the opening 16 and lead the pouring channel 2 through the opening 16. In principle, however, other tools, not shown, can also be used for this purpose. However, it is preferred to connect the Ausgießelernent 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.
