Definitions
- the invention relates to a pouring element for a composite pack comprising: a monolithic base body with a flange, a hollow-cylindrical spout defining a central axis, and a closure part formed in the spout, which runs essentially orthogonally to the central axis, with a weakened zone, a in the spout movably guided, hollow-cylindrical cutting element with at least one cutting tooth for severing the weakened zone to open the spout and composite pack, a reclosable screw cap, which serves to drive the cutting element when the composite pack is opened for the first time.
- Such pouring elements are integrated as part of the top of the composite pack for ease of handling when pouring and for reclosing the composite pack.
- This type of pouring element is shown, for example, in the applicant's EP-A-2 627 569.
- the hollow-cylindrical cutting element opens the base body and thus the previously gas-tight package for the first time and thus forms a pouring opening, with the screw cap enabling the now opened composite package to be closed again.
- the cutting element which is movably guided in the spout, is provided with force transfer elements and is thereby driven by corresponding force transmission elements on the cap.
- the cutting element approaches the closure part and after the first contact of the two elements, the cutting tooth of the cutting element separates the closure part approximately in the area of the weakened zone.
- the trajectory traveled by the cutting element corresponds to the normally annular zone of weakness.
- the opening process can be subdivided into the following sections, for example. The approaching of the cutting element mentioned above can also be omitted if the two elements are already touching in the assembled state.
- the cutting element then moves through the closure part and separates it with the cutting tooth along a cutting line. This ripping process is a combination of ripping, plastic deformation and material displacement, whereby an even and controlled application of forces is advantageous.
- the cutting element begins to swing the closure part to the side, thus freeing the spout for the contents.
- Folding away is done using the remaining piece of the weakened zone that has not been severed as a pivot axis, first the cutting tooth and then the outside of the cutting element exerting force on the closure part during the folding away, pushing it aside.
- the closure part is approximately parallel to the central axis Z along the outer wall of the screwed-in cutting element.
- pouring elements with such a closure part are mainly, but not exclusively, used in aseptic packs.
- previously sterilized foodstuffs are packed under aseptic conditions in likewise sterilized packaging means in order to then obtain so-called aseptic packs.
- aseptic packs there are various types of composite packaging 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 incorporated during the manufacturing process thereof.
- FFS Form-FilI-Seal packaging machine
- blanks made of composite material which are first formed into carton casings by sealing the longitudinal seam, are first brought into connection with the pouring element.
- These half-forms, which are open on one side, are then filled with the filling filled and then sealed.
- the first step can vary be provided:
- the flange can be connected to one side of the packaging jacket by another plastic element that is injection molded directly in the packaging machine.
- the flange can also be welded or even glued directly to the packing shell without using an additional plastic element.
- the flange can either be the same size as the opening of the packing jacket or smaller in order to save plastic. In the case of a smaller flange, the surfaces of the packing jacket must be folded together and then placed against the flange and welded.
- the composite pack then preferably has polyhedron-shaped gable surfaces which are connected in a corresponding manner to the polyhedron-shaped flange of the pouring element, the polyhedron-shaped flange essentially corresponding to a truncated pyramid.
- an initially completely sealed composite pack is produced, with a punched hole being present in the composite pack, mostly in the gable area, into which a pouring element is introduced.
- the pouring element is usually introduced by welding the flange to at least one layer of the composite material, but alternatively these parts can also be glued.
- This second type of composite pack is characterized above all by the fact that the pouring element can be introduced independently of the production of the composite pack. The production of the hole and also the introduction of the pouring element can therefore take place before, during or after the production of the composite pack itself. Both steps are preferably carried out prior to manufacture in order not to unnecessarily complicate the packaging machines themselves.
- This arrangement of the production steps also represents the simplest possibility of inserting the pouring element into the punched hole from the inside.
- a composite pack is normally made on one of two types of packaging machines.
- a continuous web of sterilized composite material is formed into a tube and sealed, after which it is filled with the contents, also sterilized, and sealed and cut at regular intervals across it. the like that The resulting "packaging cushions" are then formed into parallelepiped packs along the pre-folded edges
- the gable area can be designed differently, such as a parallel surface to the base (flat gable pack), as at least partially oblique to the base
- the exact layer structure of the composite material can vary depending on the requirements, but it consists at least of a carrier layer made of cardboard and
- a barrier layer for example aluminum (Al), polyamide (PA) or ethylene-vinyl alcohol copolymer (EVOH), may be necessary to ensure an increased barrier effect against gases in the case of aseptic filling goods and, in the case of aluminium, also against light.
- Such composite packs are therefore also referred to as cardboard/plastic composite packs.
- the pouring element is integrated as part of the composite pack, it should have a similarly strong barrier effect against gases and light as the composite material used. At the same time, of course, cheap materials should be used that are easy to recycle together. This also applies in particular to the materials used for the pouring elements.
- the present invention is based on the object of designing and developing the pouring element mentioned at the outset and previously described in more detail in such a way that the disadvantages described are overcome.
- a pouring element having the features of the preamble of claim 1 in that the base body is made of HDPE and has an oxygen transmission rate of between 12 and 23 ml Oz / (m z *day) according to ASTM D3985, measured by a measuring surface that is orthogonal to the central axis and runs through the flange of the base body.
- a lower oxygen transmission rate is desirable, since many foods packed in composite packs are sensitive to oxygen and thus have a longer shelf life.
- barrier material as a second component or a so-called scavenger material, which actively binds oxygen to itself over a limited period of time.
- the expensive and complex barrier film is therefore left out in order to obtain a monolithic base body without a film, which itself is made from more expensive HDPE, but is significantly cheaper as a whole.
- LDPE low density polyethylene
- HDPE high density polyethylene'
- Polyethylenes with a density between 940 and 970 kg/m 3 are usually considered HDPE.
- the higher crystallinity and different crystalline morphology also ensure a better oxygen barrier and thus a lower oxygen transmission rate through components made of HDPE compared to LDPE.
- HDPE usually have a crystallinity of around 50% to 80%.
- masterbatches are usually added to the base material.
- a slip agent or anti-blocking agent could be added to facilitate release of the part from the injection mold, or a light stabilizer that absorbs a certain range of wavelengths of the incident radiation, as in one of the described embodiments.
- Other commonly used masterbatches are, for example, nucleating agents, color masterbatches or agents to increase impact strength. Very often, the materials required for a particular molding process are sold pre-mixed.
- the design of the weakened zone of the base body also enables the oxygen barrier to be improved.
- the axial height of the weakened zone and also the area over which it extends is a clear influence, since the oxygen transmission mainly takes place through this area.
- the weakened zone should have a height of at least 0.1 mm, for example 0.13 mm, measured parallel to the central axis.
- the measuring surface through which the oxygen transmission rate is measured, should cover the entire base body if possible, but in any case the entire weakened zone (or its projection along the central axis onto the measuring surface] must lie within it.
- the oxygen transmission is mainly measured on foils, which are held in the measuring device by a sealing material, whereby the sealing material also defines the measuring area at the same time.
- a more complicated component such as a basic body given here, can also be measured in such a measuring device according to the standard.
- a two-component epoxy resin adhesive is used for sealing, for example "Devcon 5 Minute Epoxy", whereby the base body is attached to, for example, a sample holder adapted to the base body or any flange of the measuring device that is suitable in size.
- a basic element that are not according to the invention.
- the one known from the prior art with a barrier film attached to it which, depending on the choice of film, usually has oxygen transmission values between 2.5 and 10 ml O 2 /(m 2 *day).
- the actual basic element without a foil sealed on is in the range of 40 to 50 ml O2 / (m 2 *day) and if an LLDPE, i.e. a linear LDPE, is used instead, the values even increase to 60 ml O2 / (m 2 *day).
- a further embodiment of the invention provides that the base body has an oxygen transmission rate of less than 20, preferably less than 18 ml O2 / (m 2 * day), measured by a measuring surface that is orthogonal to the central axis and runs through the flange of the base body .
- a further teaching of the invention provides that the weakened zone has less than 50% of the height of the remaining closure part, measured parallel to the central axis. This guarantees a clean opening of the weakened zone, combined with a stable closure part that can also be folded completely to the side at the end of the opening process. At the same time this guarantees that the majority of the oxygen transmission takes place through the zone of weakness because the remaining closure part is designed significantly thicker.
- the weakening zone the lower wall thickness and the higher pressure during the Production in the tool the crystallinity. A faster cooling in the thinner
- the weakened zone is preferably even less than 25% of the height of the remaining closure part.
- the weakened zone is ring-shaped and directly adjoins the grommet.
- this enables simplified production of the base body because the transition area between the spout and the closure part can be shaped more beautifully.
- the forces during the ripping process are better transmitted and absorbed by the grommet.
- the entire pouring element allows light transmission of less than 1% in a wavelength range from 350 to 550 nm before it is opened for the first time.
- the composite pack itself also has a barrier against light transmission.
- barrier effects can come from different layers of the composite structure, such as a barrier layer made of aluminum or partly from the carrier layer. Since the composite material is not continuous in the area of the pouring element, the usual barrier effect cannot be guaranteed and it is therefore easiest and most cost-effective to supplement the pouring element with a masterbatch in such a way that it has a comparable barrier effect.
- a light barrier is particularly useful for light-sensitive products such as milk.
- the base body can also consist of at least 96 percent by weight HDPE, since the light absorption masterbatch is usually added in amounts of 4 to 6% by weight.
- Any spectrophotometer can be used for the measurement, such as a Specord 250 Plus from Analytik Jena or a Perkin Elmer LAMBDA 850+ following the manufacturer's instructions.
- the cutting element and the screw cap are also made of polyolefins.
- the base body consists monolithically of HDPE, which, as is known, is also a polyolefin.
- This choice in turn allows costs to be reduced, particularly in the case of the cutting element, compared with known cutting element materials such as polystyrene, which have hitherto been used for pouring elements with closure parts according to the invention.
- Materials such as polystyrene tend to cause problems when there are longer dwell times during the production process - for example in the event of malfunctions. This leads to thermal degradation of the material very quickly, which makes it undesirably vitreous. Such problems can be avoided by choosing a polyolefin.
- a further embodiment of the invention provides that the entire pouring element consists of renewable raw materials.
- Polyolefins are usually made from fossil raw materials such as ethane, liquid gas or petroleum. Recently, there has been an increasing search for alternatives in order to obtain more sustainable products. Instead of using the well-known fossil raw materials, bioethanol, which was produced from raw materials containing starch, sugar or cellulose, has proven to be a viable option. Preference is given here to raw materials that do not require intensive agricultural management and also grow on inferior soils. A polyolefin can then be produced from this bioethanol in the usual processes. In the present case, all components of the pouring element are made of polyolefins and can therefore can even be made from the same renewable raw materials with relatively little effort.
- the cutting element consists of polypropylene.
- polypropylene is also a polyolefin and the aforementioned advantages generally apply in this embodiment as well.
- Polypropylene is a cheap alternative to the conventionally used materials for the well-known pouring elements with closure parts.
- a further advantageous embodiment relates to a polypropylene which has a flexural modulus of at least 1900 MPa.
- a polypropylene which has a flexural modulus of at least 1900 MPa.
- a rigid material with a correspondingly high flexural modulus for the cutting element. This guarantees that the cutting element acts stably in the desired position - in the weakened zone - and also separates the closure part cleanly there, without a tooth buckling to the side, for example.
- such a material also leads to improved cutting behavior when scoring and cutting through the closure part or the weakened zone.
- the cutting tooth extends at the end facing the weakened zone in the circumferential direction in a plane orthogonal to the central axis.
- the flattened end of the cutting tooth ensures that the cutting tooth separates the weakened zone more stably and is guided along the intermediate area. If the part of the projection on the intermediate area is so large that this end extending circumferentially in a plane orthogonal to the central axis is located over the intermediate area, it also ensures that this cutting edge of the cutting tooth is directed outwards cleanly from the intermediate area until it Goes to an area thin enough to be severed, such as the weakened zone itself.
- the cutting element is thickened radially inward in the area of the cutting tooth.
- each reinforcement of the cutting element can be regarded as a thickening, which is formed protruding inwards on the hollow cylinder and has, for example, a maximum of 95% of the inner radius of the rest of the hollow cylinder.
- the cutting element has two cutting teeth.
- a cutting element will go through the severing phase more quickly and move on to folding away the more cutting teeth are formed on it, provided these are distributed reasonably regularly over the circumference.
- the opening force increases with each additional cutting tooth that simultaneously pierces the closure part with cutting teeth of the same length.
- an injection molding point on the central axis of the closure part.
- the individual components of the pouring element are manufactured using the injection molding process.
- a mold with a negative mold of the part to be produced is filled with liquid plastic, which then solidifies before the mold opens and the finished part is ejected.
- the liquid plastic is fed through a single nozzle, upon ejection the solidified molded plastic part separates from the rest of the plastic still in the nozzle. Of course, this separation can also take place before ejection via the nozzle itself.
- there is a visible and mostly protruding unevenness on the surface of the plastic part which is commonly referred to as the injection point.
- a composite pack for liquid foodstuffs is designed in such a way that a pouring element according to the invention is integrated into the gable area of the composite pack.
- a pouring element according to the invention is integrated into the gable area of the composite pack.
- the pouring element often serves primarily to close the opening in the gable area and has a more secondary effect with regard to the dimensional stability of the composite pack.
- Another advantageous embodiment of the invention relates to a composite pack which is designed such that a pouring element according to the invention is integrated into the gable area of the composite pack, the gable area having polyhedral gable surfaces which are connected correspondingly to a polyhedral flange of the pouring element.
- this combination allows a bottle-like composite pack to be formed without the need for additional components.
- ASTM D792 - 20 is used to determine the density of plastics.
- IS0178 is a suitable method.

- FIG. 17 shows a perspective view of a screw cap of the second exemplary embodiment
- FIG. 18 shows a cutting element of the second exemplary embodiment in a perspective view.
- FIG. 1 Two preferred embodiments of a pouring element 1 and 1' according to the invention are shown in the drawing in order to make the function during opening clear.
- a first pouring element 1 is shown in the closed state with a central axis Z without composite packaging P.
- a reclosable screw cap 2 which is used for the initial opening and for reclosing the composite pack P, is located on a base body 3, which is only clearly visible in FIG. 3 and of which only a peripheral flange 4 is visible in FIG and integration into the composite package P is used.
- a section line III-III is additionally drawn
- Fig. 3 shows the entire pouring element 1 in vertical section along line III-III.
- the base body 3 also has a hollow-cylindrical spout 5 and a closure part 6 formed in the spout 5 .
- the closure part 6 comprises an annular weakened zone 7, which adjoins the spout 5, a central area 8, which closes the majority of the pouring opening, and a conical ring-shaped intermediate area 9, which is located between the weakened zone 7 and Central area 8 extends.
- the bevel of the intermediate region 9 is similar to the
- This sectional view also shows that both the peripheral flange 4 and the central area 8 are approximately six times the height of the weakened zone 7 . This clearly shows how most of the oxygen will pass through the weakened zone 7, with the sealing of the screw cap 2 to this interior of the pouring element 1 never being able to be completely gas-tight.
- first pair of threads 10A and 10B which enables the screw cap 2 to be screwed on and off.
- Inside the base body 3 there is a hollow-cylindrical cutting element 11 with two cutting teeth 12 which separates the closure part 6 when the pouring element 1 and thus the composite pack P are opened for the first time.
- the central axis Z is defined by the concentrically arranged hollow-cylindrical elements of the spout 5 and the cutting element 11, with the cutting element 11 rotating about the central axis Z during the opening process and moving along it.
- This movement is defined by a second pair of threads 13A and 13B, which are located between the inside of the spout 5 and the cutting element 11. In this movement, the cutting element 11 is driven on at least one force transmission element 14 which interacts with at least one corresponding force transmission element 15 of the screw cap 2 .
- FIG. 4 and 5 it is shown how the cutting teeth 12 hit the weakened zone 7 and the intermediate area 9 and begin to separate this area.
- 3 and 4 show the original arrangement of the elements before the first opening and FIG. 5 that during the opening process.
- the cutting element 11 and thus the cutting teeth 12 are arranged over the intermediate region 9, since also with the inner delimitation of the projection of the cutting tooth 12 is shown on the projection line shown in dashed lines.
- the band 16 detaches itself from the rest of the screw cap 2 immediately when it is opened for the first time and remains visibly separated in its original position. Stop elements 18 on the band 16 which hook onto corresponding elements of the base body 3 ensure that the band 16 has already become detached from the rest of the screw cap 2 before the cutting element 11 impairs the integrity of the closure part 6 when separating.
- the anchor ring 17 also detaches during the initial opening process and then remains on the spout 5, with the anchor ring 17 and the rest of the screw cap 2 remaining connected by retaining elements.
- FIGS. 9 and 10 a single cutting element 11 is shown in two different perspective views.
- the two cutting teeth 12, which are formed at the lower end of the cutting element 11, are now clearly visible. You can also see the three force transfer elements 14 on the inner wall and the thread of the second pair of threads 13B on the outer wall.
- Weakened zone 7 is pushed to the side by the further movement of the cutting element 11 and thus releases the pouring opening.
- This segment of the weakened zone 7 is sufficient to hold the tab in its “folded away” state when the combination pack P is open, in order to reliably prevent the tab from being torn off unintentionally and the weakened zone 7 being completely severed.
- the cutting tooth 12, which is formed at the front in the direction of rotation, comes to rest at the end of the initial opening in such a way that it is level with the tab and thus keeps it stable to the side.
- the flange 4' of the base body 3' is designed here as a truncated pyramid in the shape of a polyhedron.
- the contact surfaces with the composite material of the composite pack P' are no longer in one plane, but rather are given by the four side surfaces of the truncated pyramid, as can be seen particularly in FIGS. 12 to 14.
- the basic structure of the pouring element 1' is comparable to the first exemplary embodiment: It is also a three-part pouring element 1' with a base body 3', a screw cap 2' and a cutting element 11'.
- the first pair of threads 10A', 10B' and the second pair of threads 13A' are located between the screw cap 2' and the outside of the spout 5' of the base body 3'.
- FIGS. 13B' connects the inside of the spout 5' to the cutting element 11' for movably locating it therein.
- Comparable elements for transferring force from the screw cap 2' to the cutting element 11' during the opening process are also designed, with FIGS. 17 and 18 showing that screw cap 2 and cutting element 11' are each connected by two force transfer elements 14' and force transmission elements 15' are connected to each other.
- FIGS. 15 and 16 impressively show that the cutting element 11' can also be modified in that the cutting tooth 12' is made thicker, particularly in the upper area. The cutting element 11' is thus thickened radially inwards, so that in the installed state it protrudes over the intermediate area 9' and comes into contact with it during the opening process.
