SUMMARY

[0002] The invention is based on a primary packaging, in particular a primary paper packaging, for receiving at least one product, in particular a food product, with at least one enveloping unit, which in particular comes into contact with the product directly, in particular a tubular bag, the enveloping unit, in particular the tubular bag, comprising at least one barrier layer for a protection of the received product, in particular from humidity and/or oxygen, and comprising at least one carrier layer, in particular paper layer, which is connected with the barrier layer, in particular by substance-to-substance bond.

[0003] It is proposed that the primary packaging comprises at least one functional unit, in particular damping and/or stiffening unit, which is in particular embodied in a one-part implementation with the enveloping unit, for a protection of the enveloping unit and/or of the received product from damages. The term "in a one-part implementation" is in particular to mean at least connected by substance-to-substance bond, for example by a welding process, a gluing process, an injection-molding process and/or another process that is deemed expedient by someone skilled in the art. Preferably the functional unit is formed at least partly by the enveloping unit, in particular by at least one partial region of the enveloping unit. The functional unit is preferentially configured to protect the enveloping unit, at least in a partial region, and/or the received product from transport damages. "Configured" is in particular to mean specifically constructed, specifically designed and/or specifically equipped. By an object being configured for a certain function is in particular to be understood that the object fulfills and/or executes said certain function in at least one application state and/or operation state. The functional unit is preferably arranged on the enveloping unit or at least partly formed by the enveloping unit in such a way that at least a damaging of the barrier layer, in particular caused by an excessive kinking of the enveloping unit in the region of a fold triangle of the enveloping unit, caused by transport and/or by an arrangement of the primary packaging in a secondary packaging, can be counteracted.

[0004] Preferentially the functional unit is embodied at least partially as a damping unit, which is configured to damp, at least in a partial region of the enveloping unit, shocks acting on the enveloping unit via a deformation and/or a movement of at least one element or a partial region of the functional unit that is at least partially embodied as a damping unit. Alternatively or additionally the functional unit is embodied at least partially as a stiffening unit, which is configured for a stiffening of the enveloping unit at least in a partial region, in particular for the purpose of protecting the received product from an impact of external loads, which could result in a damage to the received product. The functional unit that is embodied at least partially as a stiffening unit is preferably formed as a result of a geometric arrangement of partial regions of the enveloping unit and/or as a result of a specifically introduced or shaped surface structure in at least one partial region of the enveloping unit. For example, the functional unit that is embodied at least partially as a stiffening unit and/or as a damping unit may be implemented of stiffening elements which are additionally arranged on the enveloping unit, e.g. additional folds, additional ribs, additional stamping in the enveloping unit or similar, or of end regions of the enveloping unit itself. Preferentially the enveloping unit is configured, in a state when the primary packaging is arranged in the secondary packaging, to protect the enveloping unit, in particular from loads which can lead at least to a damaging of the barrier layer due to an impact of loads in a state when the primary packaging is arranged in the secondary packaging. Preferably the functional unit is formed at least largely, in particular completely, of a material of the enveloping unit.

[0005] The enveloping unit is preferably implemented as a paper enveloping unit. In particular, the enveloping unit is implemented of a paper by more than 50%, preferentially by more than 70% and especially preferentially by more than 80% of a total material of the enveloping unit. The enveloping unit is preferably implemented as a paper foil. The enveloping unit is preferentially implemented differently than a cardboard enveloping unit. In particular, the enveloping unit has a maximum material thickness of less than 2 mm, preferably less than 1 mm and particularly preferably less than 500 .mu.m. Preferentially the enveloping unit has a maximum material thickness that is smaller than 250 .mu.m. The enveloping unit is especially preferentially embodied as a tubular bag, in particular a tubular paper bag. The enveloping unit preferably comprises the barrier layer as well as the carrier layer, which are connected to each other. The carrier layer is preferentially embodied as a paper layer. It is conceivable that the enveloping unit has, alternatively or additionally to the barrier layer and/or to the carrier layer, further layers, in particular functional layers, which are deemed expedient by someone skilled in the art, like for example a sealing and structure layer, a blocking and structure layer, or the like. Preferably the barrier layer is embodied as a transparent PET layer. The barrier layer is preferentially configured as a barrier against oxygen. It is however also conceivable that the barrier layer is embodied as a different layer that is deemed expedient by someone skilled in the art, which is provided as a barrier against oxygen, as a barrier against water vapor, as a barrier against condensate, as a lipid barrier, as a humidity barrier, or as a different barrier that is deemed to be expedient by someone skilled in the art.

[0006] Moreover, it is also conceivable that the enveloping unit comprises, in addition to the barrier layer, a further barrier layer, which is additionally configured as a barrier against water vapor, as a barrier against condensate, or something like that. The further barrier layer may, for example, be embodied as a transparent polyethylene layer, as a metallized PP layer, or something like that. Preferably the enveloping unit comprises, in particular in addition to the barrier layer and the carrier layer, a sealing layer. The sealing layer may, for example, be implemented as an, in particular white, polyethylene layer. The sealing layer is preferably embodied to be non-transparent. The sealing layer is preferentially connected with the carrier layer, in particular connected with the carrier layer in a one-part implementation. Preferably the sealing layer is glued with the carrier layer. The barrier layer is preferably sealed with the carrier layer. Preferentially the barrier layer forms an outer side of the enveloping unit. The sealing layer preferably forms an inner side of the enveloping unit, which in particular faces towards the received product. It is however also conceivable that the barrier layer forms the inner side of the enveloping unit, which in particular faces towards the received product, wherein the sealing unit is arranged between the barrier layer and the carrier layer. Other arrangements of the barrier layer, the carrier layer and/or the sealing layer, which are deemed expedient by someone skilled in the art, are also conceivable.

[0007] The primary packaging is preferably configured for receiving products embodied as food products, like for example chocolate bars, slabs of chocolate, biscuits, cookies, cereal bars, fitness bars, sherbet-like powders, or similar. The primary packaging completely encloses the product received in the enveloping unit, in particular for a protection from oxygen, humidity or similar. The primary packaging is preferably produced in a packaging machine that is taught in DE 10 2019 132 878 A1, in particular in a horizontal tubular bag machine that is taught therein. Preferentially the enveloping unit is folded as well as transversely and longitudinally sealed, at least around the product that is to be received, by the packaging machine taught in DE 10 2019 132 878 A1. The teaching of DE 10 2019 132 878 A1 in regard to the packaging machine and to a method for a production with respect to a folding of the enveloping unit and to a longitudinal and a transverse sealing of the enveloping unit are in particular to be considered as part of the present disclosure. It is however also conceivable that the primary packaging according to the invention is produced at least partly by means of a different packaging machine that is deemed to be expedient by someone skilled in the art.

[0008] By the implementation of the primary packaging according to the invention advantageously a reliable protection of the enveloping unit and/or of the received product may be enabled. In particular in an implementation of the primary packaging as a primary paper packaging, if there is no functional unit a tearing of the enveloping unit may occur due to an arrangement in a secondary packaging, caused by, in particular excessive, kinking of end regions, in particular in the region of fold triangles, of the enveloping unit, which can be advantageously counteracted by means of the functional unit according to the invention. Advantageously packaging materials may be used which are made of delicate, in particular tear-prone and/or very thin, materials, in particular of paper, for a primary packaging of products which advantageously tend to be damaged less when transported in a secondary packaging.

[0009] It is furthermore proposed that the functional unit which is in particular at least partly embodied as a damping unit is at least partly realized by at least one fin of the enveloping unit, in particular by at least one fin of the enveloping unit created as a result of a fin seam sealing of the enveloping unit. In a fin seam sealing, first of all two edge regions of the not-yet-closed enveloping unit, which face away from each other, are arranged with their inner sides upon each other and sealed in a manner that is already known to someone skilled in the art like, for example, the manner taught in DE 10 2019 132 878 A1. It is well known that in a fin seam sealing the longitudinal sealing is done first, resulting in something like a flexible tube with a sealing on one side. By a transverse sealing, which is well known to be carried out later on, of two ends of the enveloping unit which face away from each other, a seam of the longitudinal sealing is folded back, as is well-known, and a fin of the enveloping unit is created, in particular on each end of the enveloping unit, preferably of the primary packaging. The fin of the enveloping unit preferably forms an end of the enveloping unit. In particular, a separating edge and/or a rip-open edge of the enveloping unit is arranged on the fin of the enveloping unit. Preferentially the fin of the enveloping unit is a region of the enveloping unit in which, after transverse sealing, two partial regions of the inner side of the enveloping unit are directly connected, in particular glued, with each other. The enveloping unit preferably comprises a fin on each end. Preferentially the enveloping unit comprises at least two fins, in particular precisely two fins. The fins are preferably arranged on ends of the enveloping unit which face away from each other. Preferentially the fin or the fins is/are configured to act as a damper or dampers by way of a deformation and/or a movement of the fin or the fins, in particular in case of a force acting on the fin or the fins along an axis that extends at least substantially parallel to a longitudinal axis of the enveloping unit. The longitudinal axis of the enveloping unit preferably extends at least substantially parallel to a longitudinal extension of the longitudinal sealing seam of the enveloping unit. "At least substantially parallel" is here in particular to mean an orientation of a direction relative to a reference direction, in particular in a plane, wherein the direction has a deviation from the reference direction that is in particular smaller than 8.degree., advantageously smaller than 5.degree. and especially advantageously smaller than 2.degree.. The implementation of the primary packaging according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or of the received product. It is advantageously possible to make use of a springy characteristic of the fins for a damping function, in particular in an implementation of the primary packaging as a primary paper packaging.

[0010] It is further proposed that the functional unit is implemented at least partly by a fold triangle of the enveloping unit, in particular by at least one fold triangle of the enveloping unit created as a result of a fin seam sealing of the enveloping unit. The fold triangle of the enveloping unit is preferably formed, in a manner already known to someone skilled in the art, as a result of an introduction of a transverse sealing seam. Preferentially the fold triangle is arranged in a region of the enveloping unit that extends between the fin and the received product. The fold triangle is preferably implemented by a partial region of the enveloping unit that tapers towards the fin. Preferentially the enveloping unit comprises a fold triangle on each side facing towards the respective fin. Preferably the enveloping unit comprises at least two fold triangles, in particular precisely two fold triangles. Preferentially the fold triangles are arranged on sides of the enveloping unit which face away from each other. Preferably the fold triangle, in particular each fold triangle, is arranged between, in particular spatially between, the fin and an, in particular rectangular-cuboid-shaped, receiving region of the enveloping unit, which the received product is arranged in. Preferentially the fold triangle or the fold triangles implements/implement a stiffening structure of the enveloping unit which, in particular in case of a force acting onto the fin or the fins along the axis that extends at least substantially parallel to the longitudinal axis of the enveloping unit, counteracts a deformation of the entire enveloping unit and preferably counteracts a contact between the fin or the fins and the received product. The implementation of the primary packaging according to the invention advantageously enables a reliable protection of the enveloping unit and/or of the received product. It is advantageously possible, in particular in an implementation of the primary packaging as a primary paper packaging, to make use of a stiffening characteristic of the fold triangles for a stiffening function.

[0011] It is also proposed that the functional unit is implemented at least partly by at least one, in particular the afore-mentioned, fin of the enveloping unit, in particular by at least one, in particular the afore-mentioned, fin of the enveloping unit created as a result of a fin seam sealing of the enveloping unit, wherein the fin comprises a stiffening structure, in particular in addition to a sealing structure. The stiffening structure may be realized by foldings, folds, ribs or the like additionally arranged on the fin, and/or by an introduction, in particular a stamping, of structures, like for example a honeycomb structure, a netting structure or something like that, into the fin. Preferentially all the fins of the enveloping unit have a stiffening structure. Alternatively or additionally it is also conceivable that the fold triangle, in particular all the fold triangles, of the enveloping unit has, in particular have, at least one stiffening structure. Preferably the stiffening structure has a main extension that extends transversely to the transverse sealing seam. Other implementations for an additional stiffening of the fin, in particular of all the fins, of the enveloping unit, which are deemed expedient by someone skilled in the art, are also conceivable. The implementation of the primary packaging according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or of the received product. A high degree of stiffness of the fin is achievable in a constructionally simple manner, in particular in an implementation of the primary packaging as a primary paper packaging.

[0012] Furthermore, it is proposed that the functional unit is implemented at least partly by a fold triangle, in particular by at least one fold triangle created as a result of a fin seam sealing of the enveloping unit, in particular the aforementioned fold triangle, and by a counter-fold triangle, in particular a gusset, of the enveloping unit. Preferably the counter-fold triangle is realized, in particular in a manner that is already known to someone skilled in the art, as an inwards-folding towards an inner side in the region of the fold triangle. Preferentially the counter-fold triangle is realized as a folding in a region of the fin prior to an introduction of the transverse sealing seam. Preferably at least two, in particular exactly two, counter-fold triangles, in particular at least two gussets, are arranged on the fold triangle, in particular on each fold triangle, of the enveloping unit. The implementation of the primary packaging according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or of the received product. A high degree of stiffness of the fold triangle is achievable in a constructionally simple manner, in particular in an implementation of the primary packaging as a primary paper packaging.

[0013] Beyond this it is proposed that the functional unit is realized at least partly by a stiffness parameter of the carrier layer, in particular by a paper stiffness parameter of the paper layer. Preferentially the functional unit is realized at least partly by the material-specific stiffness parameter of the carrier layer and by a geometrical arrangement, in particular by the implementation of the fold triangle. The stiffness parameter of the carrier layer that is embodied as a paper layer is preferably greater than the stiffness parameter of a carrier layer that is implemented of a synthetic foil or aluminum foil and is already known to someone skilled in the art. The implementation of the primary packaging according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or of the received product. It is advantageously possible, by using a paper layer as a carrier layer, to make use of a high innate stiffness for a stable realization of the primary packaging at least in the region of the fold triangle.

[0014] The invention is further based on a packaging machine, in particular a tubular-bag machine, for a production and/or for a transport of the primary packaging according to the invention. It is proposed that the packaging machine comprises at least one transport unit, which is implemented in such a way that during transport, in particular during transport into a secondary packaging, in particular into the aforementioned secondary packaging, the primary packaging is supported at least in the region of a fold triangle, in particular the aforementioned fold triangle, of the enveloping unit and/or a fin, in particular the aforementioned fin, of the enveloping unit is bent, arched and/or folded around at least one axis. The transport unit is preferably implemented by a gripper unit, which is configured, by means of a form-fit and/or force-fit connection, to lift the primary packaging from a product feeding unit, in particular a conveyor belt, a pick-up chain, or something like that, of the packaging machine and to convey it to a secondary packaging, in particular the aforementioned secondary packaging. The transport unit preferentially comprises at least one holding element, by means of which the primary packaging can be held for a transport into the secondary packaging. The holding element may be configured, for example, as a negative-pressure holding element, for example as a suction cup. Preferentially the transport unit comprises, in particular in addition to the holding element, at least one further holding element, by means of which the primary packaging can be held for a transport into the secondary packaging. Preferably the primary packaging is clampable between the holding element and the further holding element. The holding element and the further holding element are preferably supported on a base body of the transport unit in a translationally movable manner. It is however also conceivable that the holding element and the further holding element are supported on the base body in a rotatable or pivotable manner. Preferentially the fin of the enveloping unit is bent, arched and/or folded around an axis that extends transversely, in particular at least substantially perpendicularly, to the longitudinal axis of the enveloping unit. It is however also conceivable that the fin of the enveloping unit is bent, arched and/or folded around an axis that extends at least substantially perpendicularly to the longitudinal axis of the enveloping unit.

It is however also conceivable that the support element and the further support element are supported on the base body in a rotatable or pivotable manner. The support element and the further support element are preferentially implemented at least partly, in particular at an end that comes into contact with the primary packaging, of an elastic material, like for example a foam material, an elastomer, or similar.

In particular, the packaging material feeding unit is configured to convey the packaging material, respectively the enveloping unit, to the forming unit along a direction that extends transversely, in particular at least substantially perpendicularly, to the transport direction. The forming unit preferentially comprises at least one folding edge, by way of which the packaging material, respectively the enveloping unit, is deflectable.

[0020] The implementation of the packaging machine according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or of the received product in an arrangement in a secondary packaging. In particular in an implementation of the primary packaging as a primary paper packaging, if there is no functional unit it is possible that, due to an arrangement in a secondary packaging, caused by, in particular excessive, kinking of end regions, in particular in the region of fold triangles, of the enveloping unit, a ripping of the enveloping unit occurs, which can be advantageously counter-acted by means of the transport unit according to the invention, in a packaging state of the primary packaging. Advantageously a gentle packaging of the primary packaging in a secondary packaging can be made possible.

[0021] The invention is also based on a method for a production and/or for a transport of the primary packaging according to the invention, in particular by means of a packaging machine according to the invention. Preferably the primary packaging according to the invention is produced by means of the packaging machine according to the invention, wherein the product is received by the enveloping unit and, in particular after producing the primary packaging and receiving the product, said product is transported into the secondary packaging by means of the transport unit of the packaging machine. The secondary packaging is preferentially embodied as a cardboard packaging surrounded by a protective sleeve, in particular a protective sleeve made of a synthetic material or paper, in a manner that is already known to someone skilled in the art. Preferably the secondary packaging comprises a U-shaped support unit, which is in particular already known to someone skilled in the art and which a plurality of primary packagings according to the invention are arranged on, in particular before the support unit and the primary packagings arranged at the support unit are surrounded by the protective sleeve in a manner already known to someone skilled in the art. It is however also conceivable that the secondary packaging has a different implementation that is deemed expedient by someone skilled in the art, like for example an implementation as a paper or cardboard box or such like, which can in particular be folded open, and which a plurality of primary packagings according to the invention can be arranged in, in particular in a stacked and/or row-wise manner. The implementation of the method according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or the received product when being arranged in a secondary packaging. Advantageously it is possible to enable gentle packaging of the primary packaging in a secondary packaging.

[0022] Furthermore, it is proposed that in at least one method step, during a transport, in particular during a transport into an, in particular the aforementioned, secondary packaging, the primary packaging is supported, at least in the region of an, in particular the aforementioned, fold triangle of the enveloping unit, and/or a fin, in particular the aforementioned fin, of the enveloping unit is bent, arched and/or folded around at least one axis, in particular the aforementioned axis. Preferentially during a transport, in particular during a transport into an, in particular the aforementioned, secondary packaging, the primary packaging is supported at least in the region of a fold triangle of the enveloping unit by the transport unit of the packaging machine. Preferably, during a transport into an, in particular into the aforementioned, secondary packaging, the fin or the fins of the enveloping unit is/are bent, arched and/or folded around at least one axis by means of the transport unit. The implementation according to the invention advantageously allows facilitating a reliable protection of the enveloping unit and/or of the received product when arranged in a secondary packaging. Advantageously a gentle packaging of the primary packaging in a secondary packaging may be enabled.

[0023] It is moreover proposed that in at least one method step, during a laying-in into a secondary packaging, a fin of the enveloping unit of the primary packaging is bent, arched and/or folded around an axis, in particular the aforementioned axis, as a result from a contact with an inner wall of the secondary packaging, in particular of the support unit, and, in particular directly after this, a pivoting movement of the primary packaging is effected, in which a further fin, in particular the aforementioned further fin, of the enveloping unit is bent, arched and/or folded around a further axis. Preferably as a result of a transport by the transport unit or of a transport by the product feeding unit, the fin of the enveloping unit of the primary packaging can be brought into contact with the inner wall of the secondary packaging. It is however also conceivable that the primary packaging is laid into the secondary packaging manually in such a way that the fin of the enveloping unit of the primary packaging is selectively bent, arched and/or folded around the axis. The further axis, around which the further fin is bent, arched and/or folded, preferably extends at least substantially parallel to the axis around which the fin is bent, arched and/or folded. Alternatively or additionally it is conceivable that in at least one method step the fine and/or the further fin are/is selectively bent, arched and/or folded around the axis, respectively the further axis, already during introduction of the transverse sealing seam. Alternatively or additionally it is conceivable that in at least one method step the fin and/or the further fin are/is intentionally weakened by an introduction of a transverse sealing seam, in particular to enable an easy bending around the axis and/or the further axis. Alternatively or additionally it is conceivable that in at least one method step, after introduction of the transverse sealing seam, the primary packaging is rotated, in particular by 90.degree., by the transport unit or by the product feeding unit, and then the fin and/or the further fin are/is bent, arched and/or folded around the axis, respectively the further axis, by means of a folding unit of the packaging machine. The folding unit may, for example, be a lateral guiding sheet, which is in particular arranged on both sides of a transport path of the packaging machine, and which bends the fin and/or the further fin. Further method steps for a bending, arching and/or folding of the fin and/or the further fin around the axis, respectively the further axis, which are deemed expedient by someone skilled in the art, are also conceivable. The implementation according to the invention advantageously enables facilitating a reliable protection of the enveloping unit and/or the received product during an arrangement in a secondary packaging. Particularly preferably, selected bending, arching and/or folding of the fin in order to enable an advantageous damping characteristic realized by the fin is achievable already during a laying-in of the primary packaging into the secondary packaging.
