Definitions

• the invention relates to a spout for a container, in particular for food products, with a closure means for aseptic sealing of the container.
• the container must meet high hygiene requirements. Especially in food products, such as fruit preparations, the container must be as germ-free as possible. In particular, it must be ensured that the once sterilized containers remain aseptic until filling.
• the outlet nozzle of the container is connected to a filling system.
• a closure means guaranteeing the aseptic state of the container is usually removed from the outlet connection. In this method, however, a contact of the outside air with the interior of the container.
• the closure means comprises a multilayer film wherein one of the layers is perforated such that the closure means bursts along a perforation under a predetermined compressive load generated, for example, by the food product flowing into the container.
• the second layer does not have this perforation, the interior of the container can not come into contact with the environment until it is pressurized. The interior thus remains germ-free.
• the outlet nozzle without the existing for aseptic sealing of the container closure means must be removed in advance from the outlet nozzle.
• the closure means bursts by the pressure of the product.
• the at least two layers of the closure means may have different light absorption properties.
• the one layer can be perforated by light absorption, while the other layer, the light of this wavelength / n as unabsorbed as possible, consequently, as undamaged as possible.
• high-energy light sources such as lasers, are suitable, due to the different absorption properties, to perforate the one layer of the film according to a predetermined pattern.
• the second layer of the multilayer film can cover at least one opening of the outlet nozzle sealing. Thanks to the dense attachment of the second layer to the outlet opening of the outlet nozzle aseptic sealing of the container can be made possible.
• the closure means may in this case be attached to the side of the outlet nozzle facing the container or attached to the side of the outlet nozzle, which may be facing a filling device. Eventually, a closure means can also be provided on the two sides of the outlet nozzle.
• the perforation of the first layer of the film may be formed so that the closure means bursts under the predetermined pressure load without separating from the outlet nozzle.
• the perforation may comprise an open circular arc.
• the circular arc can be designed so that when bursting the split surface of the multilayer film approximately corresponds to the inner cross-sectional area of the outlet nozzle, so that the inflowing product flow is as little as possible braked by the still in the flow path closing means.
• solid components in the product stream such as pieces of fruit in the product, are prevented from sticking to areas in the way and becoming damaged, such as crushed.
• the ends of the circular arc can be bent outwards. This prevents departure when bursting the closure means.
• the bent part can extend beyond the outlet opening, in particular into the region where the closure means is fastened to the outlet nozzle. Due to the fact that the perforation ends in an area where the closure means is fastened to the outlet connection, for example by welding, the closure means bursts only along the perforation and can not continue to develop.
• the perforation may have at least two lines.
• lines are easy to realize.
• the lines can run obliquely to each other. The closer the lines are to each other, the lower the required pressure load. This means that the multilayer film will burst first at this point and then burst further along the perforation lines. This prevents the departure of a portion of the film by uncontrolled travel.
• the perforation of the first layer can be formed cross-shaped or star-shaped. Thanks to these perforation geometries, the largest possible flow opening for the product flow through the burst open closure means can be achieved.
• intersection of the cross or the star can be arranged in the middle of the outlet opening of the outlet nozzle. This serves to further optimize the flow rate in the burst state.
• the first layer may be polyethylene terephthalate (PET) or PETP and / or the second layer may be polyethylene (PE), LLDPE or polypropylene (PP).
• PET polyethylene terephthalate
• PE polyethylene
• PP polypropylene
• the outlet opening may be made of HDPE.
• HDPE is particularly suitable in connection with the above-mentioned multilayer multilayer film since PE, PP and LLDPE can be sealingly applied to HDPE.
• the closure means may be designed so that it bursts at pressures from 100 mbar, in particular in a range of 300-500 mbar. This prevents unwanted bursting. Likewise, it is possible to clean the environment-facing side, in particular to disinfect or sterilize without the closure means bursts.
• the first layer may preferably have a layer thickness of 10 to 15 ⁇ m, in particular of 12 ⁇ m, and / or the second layer may have a layer thickness of 40 to 60 ⁇ m. These thicknesses allow both the perforation, as well as the setting of the desired pressure range in which bursts the closure means.
• the invention further relates to a container, in particular for food products, with an outlet connection as described above. Thanks to the use of the outlet nozzle, the inside of such a container can be protected from the negative influences of the outside world until it is filled.
• the container may, for example, be an inliner to which the outlet nozzle is attached. Such inliners are used in bag-in-tank systems.
• a method for producing a closure means for attachment to a spout comprises the steps of providing a multilayer film of at least two layers and perforating a first layer at predetermined locations so that the closure means pops open under a predetermined compressive load. It is irrelevant whether the perforation is performed before attaching the closure means at the outlet nozzle or after attachment to the outlet nozzle. As already explained in connection with the outlet nozzle explained above, such a closure means makes it possible to protect the interior of a container, on which the outlet nozzle is attached, until it is filled with negative environmental influences.
• the two layers may preferably have different light absorption properties, so that the first layer can be perforated with light, in particular laser light, while the second layer remains unchanged. Thanks to the different light absorption properties, it is thus possible to perforate an already produced multilayer film so that one layer has the perforation, while the other layer remains as uninjured as possible, so that the film preserves the required sealing property.
• the invention further relates to a closure means for attachment to an outlet nozzle, wherein the closure means comprises a multilayer film having at least two layers and that the two layers have different light absorption properties.
• the closure means comprises a multilayer film having at least two layers and that the two layers have different light absorption properties.
• the one layer may be perforated at predetermined locations.

• FIG. 2 shows a second three-dimensional sectional view of the first embodiment
• FIG. 3 shows a second embodiment of the outlet nozzle according to the invention
• FIGS. 4a to 4g show various perforation patterns of the multilayer film serving as closure means of the outlet nozzle

• FIG. 6 schematically shows a flow diagram for illustrating a method for producing a closure means for attachment to an outlet connection.
• Figure 1 shows a three-dimensional sectional view of a first embodiment of the outlet nozzle according to the invention for a container, in particular a container for food products.
• the container used is, for example, a bag or inliner, which receives the products and is arranged for transport within a tank (bag-in-tank transport system).
• the outlet connection 1 comprises an outlet channel 3 and preferably arranged integrally thereon a ring 5 with which the outlet connection 1 is attached to a container (see FIG. 5). On the side of the ring 5 facing away from the channel 3 there is a connection Closing means 7 for aseptic sealing of the channel 3 and thus for aseptic sealing of the container is attached to the outlet nozzle 1.
• the closure means 7 comprises a multilayer film having at least a first layer 9 and a second layer 11.
• the second layer 11 is sealingly attached to the ring 5, so that the channel 3 is closed.
• the first layer 9 has a perforation 13, in the form of a cross in this embodiment.
• a seal 15 and a connecting thread 17 are furthermore arranged.
• a filling or emptying device not shown here, can be connected to the outlet 1.
• the channel 3, the ring 5 and the thread 17 are integrally formed. Alternatively, however, these elements may also represent their own parts that are assembled together.
• PE for example, by heat welding or ultrasonic welding, sealable to the HDPE of the outlet nozzle 1 can be attached, and thereby close the channel 3 tight.
• the use of PET as the first layer 9 and PE as the second layer 11 has the advantage that thanks to the light absorption properties of PET, the perforation 13 can be realized with a laser, while, thanks to different light absorption properties, the second layer 11 in the perforation of the first layer 9 remains unhurt. Equally conceivable, however, is the use of PETP as first layer 9 and PP or LLDPE as second layer 11.
• the perforation 13 of the first layer 9 of the closure means 7 allows the closure means 7 to pop open under a predetermined compressive load along the perforation. If a fluid, for example a food product stream, flows in the channel 3 - in the direction A - against the side 19 of the second layer 11 facing the channel 3, a pressure builds up there. As soon as this pressure exceeds a certain value, the second layer 11 ruptures in the vicinity or at the perforation 13 of the second layer 9, since there the closure means 7 is weakest. By the defined tearing is guaranteed that the closure means ruptures without tearing, so that no pieces of film enters the container, which is located on the side facing away from the channel 3 side of the connecting piece.
• the thickness of the second layer 11 and the shape of the perforation pattern decide on the pressure from which the closure means bursts.
• the closure means 7 bursts open even at low pressures, which occur, for example, when the channel 3 is sterilized before the inflow of a product.
• Such sterilization is carried out, for example, with hot steam, in particular steam, or H 2 O 2 in the gaseous phase.
• the closure itself is usually sterilized by gamma irradiation.
• the closure means should withstand pressures of at least 100 mbar before bursting. Preferably, however, it should burst open in a range of 300-500 mbar.
• embodiments are also possible in which the closure means bursts only at 2 bar.
• Film thicknesses of 10 to 15 ⁇ m, in particular 12 ⁇ m, for the first layer 9 and 40 to 60 ⁇ m for the second layer 11 have proven suitable for use.
• the perforated layer 9 is located on the side facing away from the channel. According to a variant, however, this layer could also face the channel 3, but then under the condition that it is sealingly attached to the ring 5.
• the closure means 7 is constructed of a two-layered film. However, it is also possible to use more than two layers.
• Figure 2 shows a further three-dimensional sectional view of the first embodiment of the outlet nozzle 1, but this time with respect to the closure means 7 from the other side.
• FIG. 2 shows that the closure means 7 with the second layer 11 sealingly covers the opening of the channel 3.
• FIG. 3 shows a second embodiment of the outlet nozzle according to the invention for a container, in particular for food products.
• the outlet connection 31 differs in comparison to the outlet connection 1 of the first embodiment only in that the Closure means is not arranged on the ring 5, but the channel 3 on the side facing away from the ring 33 sealingly covered.
• the further features of the outlet nozzle 31 correspond to those of the first embodiment and are therefore not repeated in detail.
• This embodiment has the advantage that, prior to the connection of a filling device, only the surface of the closure means 7 facing the environment has to be cleaned, in particular disinfected or sterilized.

• the perforation lines 13a, 13b could also end at the level of the channel 3.
• the perforation lines 13a, 13b are shown continuously. Alternatively, however, these lines can also be formed by dashed lines.
• Figure 4b shows an embodiment in which, thanks to the star-shaped formation of the perforation lines 13a, 13b and 13c, the closure means comprises six segments 43a to 43g, while in the cross shape there are only four segments.
• the flow opening is larger than in comparison to the cross shape of FIG. 4a.
• three lines intersect at the intersection, it must be ensured that no perforation occurs in the closure means at the perforation process at this point.
• a star-shaped perforation configuration with more than three lines could be used and / or each individual of the perforation lines could also end at the level of the edge of the channel 3.
• FIG. 4c An altered geometry is shown in FIG. 4c.

• the perforation pattern of this embodiment is circular arc-shaped, wherein the radius r of the circular arc 47 is less than or equal to the radius R of the channel 3.
• the radius r is only slightly smaller than the radius R, for example by 5%, so that after tearing an area which is approximately equal to the cross-sectional area of the channel 3, arises. So that no foil material can enter the interior of the container, the circular arc 47 is not completely formed.
