BACKGROUND

Such a film mentioned at the outset or a packaging made therefrom is known, for example, from the published international patent application WO 91/06488 known. There, such a package is used for packaging a multi-piece packaged goods in the form of three waffles. The package is disclosed as a tubular bag package having a top and a bottom transverse seam and a fin-type longitudinal seam extending between the top and bottom ends, the longitudinal seam being applied to the package. The longitudinal sealing seam is produced by cold-sealing of two strip-shaped edge zones of the film which have been pressed on one another. In that of the two edge zones, which faces away from the packaging during the longitudinal sealing seam applied to the packaging, that is to say is visible, two incisions adjacent to one another are punched, which form a gripping tab Limit opening aid, with the help of which a strip of material of the film can be torn out of the packaging in the transverse direction to the longitudinal sealing seam.

As a multi-piece packaged goods three wafers are disclosed, which are along the or parallel to the longitudinal sealing seam aligned side by side with the packaging packed. The packaging of such packaged goods usually takes place on high-speed flow-pack machines. The packaging can be torn by tearing on the handle tab strips and the thus exposed waffles can then be removed.

The known packaging has the problem that it is often not intuitive for a user to see how the package is to be opened. This particular because the opening aid is formed only in a limited area of the film. Consequently, it is not only in a misuse (an arbitrary tearing at any point of the package) but also in a planned use of the packaging mostly unsightly cracking or breaking training in the packaging, which ultimately leads to a lesser product impression for the user. In most cases, part of the opened package will hang in a more or less arbitrary orientation on another part of the package, which is held with one hand. Since the sealing zone often represents the strongest part of the packaging, the two incompletely separated parts of the packaging usually adhere to one another over an area of the sealing zone. A complete separation of the two parts requires a corresponding reworking of the user, which is often perceived as disturbing and annoying.

In addition, in a waffle-like packaged goods there is the problem that the package can not be broken because a waffle is very porous and can hardly withstand forces transmitted through the foil to the waffle during a break-up attempt. The result of such a Aufbrechversuchs is often a completely destroyed, mostly crumbled waffle that can no longer be grasped. In order to allow the packaging to break up, the packaging would have to be made from an extremely thin and filigree film so that the barrier properties of the packaging would suffer. This is not acceptable.

It is therefore an object of the invention to provide a film for producing a packaging of a packaged product, a packaging made from such a film or a packaged goods packaged with such a packaging and a use a film for packaging a packaged goods or a method for packaging such packaged goods and a device for packaging said packaged goods, so that the above-mentioned problems are avoided.

A waffle (wafer), in its simplest form, is a flat pastry consisting essentially of flour and water, which is baked between two hot iron (waffle irons). There are many different variations due to form and recipe. Popular variants are sprinkling with powder or icing sugar or serving with whipped cream. However, waffles are also used as part of a product, e.g. B. a cuts used. A cut is formed by a plurality of superimposed wafers between which a layer of e.g. chocolate-containing mass. Such cuts may also be provided with a sugar-containing and / or chocolate-containing coating.

A film according to the invention can be supplied in the form of a roll. The direction in which the film is pulled off the roll is referred to as the direction of travel. This direction corresponds to the longitudinal direction of the film.

The term opening zone is to be understood as two possible embodiments.

On the one hand, the term opening zone may indicate a portion of the film in which prior to manufacture of the package, e.g. when unwinding the film from its transport or storage role an opening is made. As soon as the packaging is formed, the opening in the film also exists. The unwound from its transport or storage roll film therefore has no opening in the opening zone. In the present case, the opening zone is the area in which an opening is to be created when using the film. Such a production of the opening is carried out only when you use it in a packaging company.

On the other hand, the term opening zone may indicate a portion of the film in which the film has already been used in the manufacture of the film, e.g. before winding the film on its transport or storage role an opening was made. In the present case, the opening zone is the area in which an opening already exists when using the film. Such a production is already carried out during its manufacture in a film production plant.

Both interpretations are to be used below in relation to the film.

Seal seams of the package (e.g., longitudinal seal seams, but also transverse seal seams) can be made by heat-sealing of adjacent thermoplastic regions of the film. In particular, in the packaging of products that are sensitive to heat, such as chocolate-containing packaged goods, however, the use of cold sealing has prevailed. Adhesive regions of the film, such as e.g. the first and the second marginal zone of the film, pressed together with pressure. Used here are cold-sealing, in particular also approved for food contact adhesive. For example, a solvent-free or solvent-containing adhesive having a bond strength of 3N / 15mm may be used. As a method of measuring the bond strength, the DIN53357 standard is mentioned here. Thus, in the production of the longitudinal sealing seam, the film delimiting different edge zones of the film are joined together. In contrast, two identical edges of a strip of the film are joined together in the production of the head-side and foot-side transverse seam.

The fact that both the first and the second opening or opening zone at a respective distance - the same size as the other Distance or different size compared to the other distance can be - located to the film edge, allows reliable machine handling of the film on a high-speed flow-packing machine. Due to the opening-free area along the respective film edge, the film acquires the necessary stability for use on such a flow-pack machine. The safety zone created by the opening-free region along the respective film edge is formed on both sides along the entire film and provides the necessary stability which is required for folding the film along the longitudinal direction around the article to be packaged, since extreme stresses occur at the two edges of the film , This reliably prevents unwanted tearing at the edge of the film.

In principle, the two openings produced in the respective opening zones can be identically shaped or identically produced (that is to say produced using the same technique). However, there may be differences in terms of the shape and / or the manufacturing technique used. Thus, for example, both openings may have been produced by a cutting process or by a punching process. The difference is that in a punching process, a larger opening width is achieved because material is punched out of the foil, whereas in one cut only one area of the foil is separated from another area without removing material from the foil. However, it could also be an opening made by a cut and the other opening by a punching process, which sometimes bring advantages in terms of at least partially congruent positioning in the longitudinal seam to be produced, because the necessary for positioning tolerance through the opening width of the punching obtained opening can also be larger. Also, one of the two openings or both openings can be made by the action of a laser beam. This can be advantageous if the weakening zone is also produced by the same laser light source and thus an efficient, because multiple use of a working fluid is given.

With reference to the longitudinal direction, the two openings or opening zones are defined or formed essentially at the same position, so that when the film is folded over or folded over transversely to the longitudinal direction, the packaged goods to be packaged-that is to say with a hose formation-are said to have been Longitudinal seam opening in the longitudinal seam to be produced arises as soon as the first and the second edge zone are placed on each other and sealed together. Substantially in the same position in the present case means that the two openings or opening zones can also have a local offset in the longitudinal direction, but the offset must be smaller than the larger of the two opening widths measured in the longitudinal direction, so that said longitudinal sealing seam opening can be produced , The same applies essentially to the position of the two openings or opening zones in the transverse direction to the longitudinal direction. Preference is given to a completely congruent positioning of identically formed openings or opening zones.

By the measures according to the invention is achieved in an advantageous manner that an opening aid with an intuitive to use opening initiation aid in the package can be integrated. The opening initiation aid is formed by the longitudinal sealing seam opening in the finished longitudinal sealing seam of the packaging. The opening initiation aid is preferably free of any additional openings or weakenings in the film which run in the longitudinal direction. This prevents tearing of the longitudinal seal by a user in a manner other than the intended manner. A user of the package immediately recognizes that the opening of the package in the longitudinal seal has to begin, due to the visually and ductile longitudinal seal opening. By pulling the longitudinal sealing seam opening out, the longitudinal sealing seam begins to tear and is first completely separated into two parts, after which two cracks in the film propagate following the weakening zone. Now, if the packaging is further torn open and ultimately separated into two parts, the problem of a final demolition in the longitudinal sealing seam is completely avoided, because the longitudinal sealing seam has already been completely destroyed and the cracks in the film of the packaging from there predominantly symmetrical in the Spread foil away from the longitudinal sealing seam. From a functional point of view, the invention thus implements a foil and a packaging made therefrom

Opening initiation aid, which allows initiating the opening operation starting at the longitudinal seam, wherein the longitudinal sealing seam is first completely - preferably transversely to the longitudinal direction - broken so that two separate Längssiegelnahtteile are obtained, and then a Divide the packaging by further pulling apart of the two parts of the package - preferably by pulling apart the two separated longitudinal seam parts - is possible, wherein in the pulling apart of the parts of the package starting from the broken longitudinal seam two mutually away cracks in the package - following Weakening zone - spread.

Through the positioning of the opening initiation aid in the longitudinal sealing seam and the complete destruction of the most stable structure of the packaging, ie the longitudinal sealing seam, which takes place upon initiation of the opening, the film itself can accordingly be made stable and thick in order to easily provide or ensure the required barrier properties can. The already torn film can namely well along the weakening zone, which serves as a circumferential predetermined breaking point tear further. As a result, the packaging can be easily broken into two parts, wherein the final demolition of the film parts, where the package is separated into two parts, in a region outside the longitudinal sealing seam - preferably on that of the longitudinal sealing seam opposite side of the package - is displaced. For the entire tear-off process, one part of the longitudinal sealing seam can be held with one hand and the other part of the longitudinal sealing seam with the other hand.

In addition, a decisive advantage in the production of packaging is obtained. It has proven to be extremely advantageous that the two openings come to rest in those edge zones which serve to produce the longitudinal sealing seam. In fact, in comparison to the transverse sealing seams, it is easier to bring the two openings in the longitudinal sealing seam to be produced into an at least partially congruent state. The edge regions extending in the longitudinal direction (corresponding to the direction of unwinding of the film from a film roll) are in fact folded into individual parts prior to the separation of the film, resulting in a relatively good parallel alignment of the film edges extending in the longitudinal direction relative to one another. This also makes it possible to position relatively small openings congruently in the longitudinal sealing seam. A possible offset of the edge areas and thus the two openings can therefore hardly be present in the longitudinal direction. Rather, it is to be expected with a possible offset in the transverse direction, but this in a simple manner by choosing an appropriate size of the Openings can be compensated. In the production of the transverse sealing seams with a transverse sealing seam opening, an at least partially congruent positioning of openings in the edge zone of the film to be used as a transverse sealing seam would only have to be ensured with relatively high outlay and extremely unreliable, because here the required accuracy in superimposing individual components to be sealed with one another is customary Areas is not given and can be expected with an offset of the two openings in each direction.

Even if the longitudinal sealing seam and the weakening zone can be situated at any desired position along the packaged goods to be packaged, which may be in one piece in the longitudinal direction, it has proved to be particularly advantageous if the longitudinal seam opening and the weakening zone in the finished manufactured packagings a head region or in a foot region adjacent to the respective transverse sealing seams are positioned. Positioned there, for the first time, an opening process is made possible in which a relatively small part of the packaging in the form of a cap can be separated from another, relatively large part of a packaging. Particularly in the case of oblong, longitudinally oriented wafers, the advantage is obtained that the waffles can continue to be held well with the remaining large part of the package and can be pushed out at the foot or head end of the packaging as required by the access which has been removed by removing the cap ,

In addition, the longitudinal sealing seam opening produced during the packaging and the weakened zone can still be highlighted by a corresponding imprint on the film, wherein the imprint can be produced in a simple manner already with the usual printing of the film with various motifs and details of the product. Also, therefore, no additional operation is necessary. The visual accentuation of the opening initiation zone and / or the attenuation zone facilitates its precise location for a user of the package.

The weakening zone may be formed continuously, ie contiguously (eg in the form of a continuous line), or discontinuously (eg in the form of weakened segments or lines which are arranged in a line at a distance from one another). In the case of the discontinuous formation of the weakening zone, the advantage is obtained that the non-weakened regions between the weakened areas increase the stability of the film for processing and use as packaging. The non-weakened areas, such as web-like areas between segments of the weakening lines stabilize the mechanical properties of the film and thus facilitate their processing. The shape of the line may be straight, curved or serrated or zigzagged.

The manufacture of the package from the film may e.g. by means of a suitably adapted horizontal-form-fill-and-seal machine or vertical-form-fill-and-seal machine.

Further, particularly advantageous embodiments and modifications of the invention will become apparent from the dependent claims and the following description. In this case, features of the packaging, the use of the method, the device and the product according to the dependent claims may be further developed to the film. Advantages that are disclosed in connection with an object of the invention, apply in a corresponding manner for another subject of the invention or its development.

Another aspect of the invention solves a long-standing problem in the packaging of multi-piece packaged goods. In the packaging and the associated possibility of removing the multi-piece packaged goods, the known solution proves to be problematic, because only a piece of the packaged goods can be wrapped with a part of the packaging with one hand. The other piece of the packaged goods must be gripped with a bare hand or with a tissue paper or similar objects to prevent contamination of the gripping fingers of the hand removing the piece of packaged goods. The user must therefore resort to tools to prevent contamination of the hand or his fingers.

Also, to solve this problem, the invention discussed above can be used in the context of further development. First, it is assumed that the packaged goods are multi-piece and two pieces of the packaged goods are arranged side by side along a separation zone. The orientation of the separation zone extends in the transverse direction, in particular at an angle of 90 ° to the longitudinal direction of the film used for packaging. However, the orientation may also deviate from an angle of 90 ° and extend, for example, in a range up to 10 ° relative to the longitudinal direction. Your direction or Alignment ultimately depends on the shape and / or orientation of the adjacent areas of the two pieces of packaged goods. Depending on the contour of the juxtaposed pieces of the packaged product, the width of the separating zone can have a value of a few mm to a few cm and corresponds to the width which has the area covered by the contiguous contour of the two pieces. Depending on the packaged goods, two pieces but also three, four or more than four pieces can be arranged side by side and several such arrangements are parallel to each other. Each piece may, for example, have a length of 1 to 20 cm and a width or thickness of 0.5 to 5 cm.

According to the invention, the two openings or opening zones are now located corresponding to the separation zone and / or the weakening zone follows the separation zone or its orientation within the separation zone. The two openings or opening zones are therefore located within that region of the film which comes to lie above or below the separation zone of the two pieces in the packed packaged goods.

The advantageous positioning of the openings or opening zones and / or the weakening zone allows a purposeful destruction of the longitudinal sealing seam - ie the strongest zone of the package - by an intuitive tearing of the longitudinal sealing seam in the transverse direction in the region of the longitudinal sealing seam opening, a subsequent tearing of adjacent to the longitudinal sealing seam areas of the Film along the weakening zone by further pulling apart the already separated parts of the longitudinal sealing seam, and a gripping the two still packed parts of the packaged goods, as well as a break-unfolding and pulling the two still packed parts of the packaged goods, wherein the two separated parts of the longitudinal seam further from each other be removed and wherein only the respective crack in the film along the weakening zone is to continue, which is accomplished with relatively little effort. In addition, there is no force transmission from the film to the packaged packaged goods in the fracture movement, since this is already exposed on the side of the longitudinal sealing seam exactly in the separation zone. Depending on the design, the longitudinal sealing seam can be positioned within or slightly outside the separation zone. The same applies to the weakening zone. Also, either the longitudinal sealing seam or the weakening zone may be located inside or outside the separation zone. This can be used, for example, to in order to obtain a piece of the packaged item largely protected by one part of the package, whereas the other piece of packaging can still be kept well protected by the other part of the package, but at the same time beyond this part of the package - favorable for immediate consumption protrudes.

This also ensures that a clean separation of the packaging in two parts can be done exactly at the separation zone or in their vicinity. Such a separate package ultimately has two parts which expose exactly the separation zone or a part or an adjacent region thereof. Thus, even the packaged goods can be separated without any risk of structural damage to the waffle-like packaged goods into its individual pieces and held with the respective part of the pack on the one hand in the left hand and on the other hand in the right hand. The risk of contamination of the hands by the individual parts of the packaged goods is therefore avoided.

Although it is sufficient that the openings or opening zones and / or the weakening zone are positioned corresponding to the separation zone, according to an advantageous development of the invention, the two openings or opening zones are positioned corresponding to a separating line located within the separation zone, the dividing line between the two pieces of the packaged goods runs. In addition, it may be advantageous if the weakening zone also corresponds to the dividing line located within the separation zone. Thus, the opening or parts of the package can be carried out more precisely, whereby the course of the packaging edge obtained by dividing the packaging can be adjusted relatively precisely to the course of the dividing line between the two pieces of the packaged product, ie an aesthetic fracture of the packaging on the one hand eg the dividing line between the pieces of the packaged goods follows, and on the other hand a functionally favorable access to the pieces of the packaged goods is obtained because the two parts of the package do not or only marginally protrude beyond the pieces.

Another aspect of the invention relates to the structure of the film, wherein the film as an outer layer having a plastic layer and as an inner layer which points in the packaged with the foil packaged goods to the packaged, or as part of such an inner layer has a barrier layer and the weakening zone only outside the inner layer of the film or even up in the inner layer extends into it, whereby in each case the barrier function of the film must remain undamaged. However, a barrier situation is not absolutely necessary. The weakening zone may be formed on the outside of the film or on the inside of the film.

Possible realizations of the film may include the following forms of training, which are not to be construed as exhaustive enumerated. The barrier function of the film ensures that there is no inadvertent or unwanted transport of material from the packaged product to the environment of the pack or from the environment of the pack to the packaged product. The film or the laminate may have a reverse-printed polymer film as the outer layer, which in addition to customary product-specific imprints has a marking imprint for marking and improved recognition of the weakened zone. The film may comprise a metallized polymer film as an inner layer bonded to the reverse printed polymeric film via an adhesive layer in contact with the metallization. The resulting adhesive-laminated laminate may additionally have on its inside, which faces the product, a paint, which is approved for food contact. In addition, cold-sealing zones are formed, which serve for producing the sealing seams for the sealed packaging.

According to another embodiment, the aforementioned metallized polymer film may be replaced by another film - e.g. an aluminum foil - which has a lacquer on its side facing the product, which is approved for food contact.

In the context of the previously discussed embodiments of the film, possible realizations of the weakening zone may have the following forms of embodiment, but these should not be construed as exhaustive.

The zone of weakening may be generated by mechanical scoring, which may extend through the reverse printed polymeric film (eg, OPP) (corresponding to the outside of the package), the adhesive layer, and all the way to the metallized polymer film, and the metallization remains undamaged. The metallization is in contact with the adhesive layer in this layer construction and the polymer of the metallized polymer film is in contact with the packaged product. However, this scratching can also be generated by the action of a low-energy laser which is then reflected at the metallization so that the barrier function is maintained.

If an aluminum foil is used instead of the metallized polymer film, the weakening zone also extends only as far as this aluminum foil in analogy to the explanations in the preceding paragraph.

Preferably, the weakening zone is formed only outside the inner layer of the film, that is, for example, only in the outer layer and further intermediate layers. Such a designed weakening zone, for example, relatively simple and inexpensive and above all very quickly and with high reproducibility using a laser beam (eg a CO ₂ laser) are produced, which evaporates the material of the outer layer and possibly further intermediate layers and on the metallic or metallized layer or generally on a layer with different optical properties compared to the overlying layers is reflected. However, the weakening zone can also extend into the inner layer, in which case the tightness of the film with respect to its barrier function must remain undamaged. Therefore, in this case, a manufacturing method for a weakening zone is used, in which the inner layer is not penetrated. Such a method is given for example by a stamping process. However, it is also possible to use the combination of a laser beam and an embossing tool. The laser beam then removes, for example, the outer layer and possibly further intermediate layers, and the embossing tool then finally embosses the inner layer. Ultimately, the layer that realizes the barrier function may also be an intermediate layer, so that the weakening zone may extend as far as this intermediate layer. If the weakening zone is formed on the inside of the film, then statements made in the preceding also apply correspondingly to this case. Accordingly, the generation of the weakening zone then takes place from the inside.

The shape of the openings may be square, rectangular, oval, circular, etc. According to a further, preferred aspect of the invention, the two openings are formed linearly in the edge zones and the orientation of the lines runs in an angular range of 90 ° ± 30 ° or even more relative to the longitudinal direction. This allows a variable Design of the shape of the longitudinal sealing seam opening. Thus, at an obtuse angle in the range of 90 °, the length of the longitudinal sealing seam opening must always be shorter than the width of the longitudinal sealing seam measured in the transverse direction to the longitudinal direction. This can disguise the desired intuitive access to rupture of the package with a narrow longitudinal sealing seam and it may therefore be cheaper to choose a different angle in the range of eg 30 ° relative to the longitudinal direction, because then the length of the longitudinal sealing seam opening even greater than the width of the longitudinal sealing seam can be.

According to a further aspect of the invention, one of the openings or opening zones, in particular both openings or opening zones, is offset in the respective edge zone off-center relative to the center of the respective edge zone towards the respective edge of the film. This has the advantage that on the one hand the required safety zone for the film is still given. On the other hand, a necessary stability of the area between the outer edge of the longitudinal sealing seam and longitudinal sealing seam opening and at the same time a reliable hermetic closure of the packaging is ensured at that region facing the inner edge of the longitudinal sealing seam. The area between the inner edge of the longitudinal sealing seam and the longitudinal sealing seam opening is thus dimensioned larger than that between the outer edge of the longitudinal sealing seam and the longitudinal sealing seam opening.

It has proved to be particularly advantageous if the weakening zone extends from the first opening or opening zone up to the second opening or opening zone. The openings or opening zones thus form the extension of the weakening zone. This has the consequence that a tearing operation, beginning at the longitudinal sealing seam opening caused by the weakening of material in the weakening zone forcibly follows the course of material weakening and thus an unwanted course of the further fracture or cracking process is avoided in the film.

In order to ensure the necessary safety zone, the distance between the longitudinal edge and the opening or opening zone may have a value in the range of 1 to 6 mm, preferably 2 to 5 mm in the respective edge zone.

In order to ensure reliable production of the longitudinal sealing seam opening, the width of the opening or opening zone can be measured in said longitudinal direction have a value in the range of 0.1 to 1.5 mm, preferably 0.5 to 1 mm.

A secure and sustainable hermetic sealing of the packaging in the region of the longitudinal sealing seam is obtained when the length of the respective opening or opening zone measured transversely to said longitudinal direction is dimensioned such that between an inner edge of the longitudinal sealing seam to be produced and the openings or opening zone opening-free region with a width in the range of 1 to 5 mm, preferably 2.5 to 3.5 mm is formed.

DESCRIPTION OF THE EMBODIMENTS

In the Fig. 1 a package 1 for a two-piece waffle-like packaged product 3 is shown. The packaged product 3 consists of a first piece 3A and a second piece 3B and is schematically illustrated next to the packaging 1 for the purpose of clarifying its structure. Where the two pieces 3A and 3B abut, a dividing line 26B is projected onto a film 2 from which the package 1 is made. The film 2 is a composite film. Of the The entire area of that projection on the film 2, in which the two pieces 3A and 3B nestle against each other, is referred to as separation zone 26A. The parting line 26B thus runs within the separation zone 26A. For clarification, the separation zone 26A and the parting line 26B are shown both in the packaged goods 3 and in the packaging 1.

From the packaging 1, its front side 4 and its right side 5 as well as a first transverse sealing seam 6 with a first smooth end 6A and a second transverse sealing seam 7 with a second smooth end 7A are visible. The smooth ends 6A and 7A prevent rupture of the transverse sealing seams 6 and 7. Furthermore, a weakening zone 8 is visible, which extends substantially along the center of the package 1, which in the present case corresponds exactly to the center of the separation zone 26A, the weakening zone follows. The package 1 is held with the right hand 22 of a user, with the right hand 22, the package 1 supported from below.

The fragmentary in the form of a cross section in the Fig. 14 illustrated film 3 has an outer layer 9 and an inner layer 11 and a barrier layer 10 arranged therebetween. The weakening zone 8 is formed linearly only in the outer layer 9, so that the barrier layer 10 is undamaged and therefore dense.

In the Fig. 2 the back 12 and a left side 13 of the package 1 is visible. Also visible is also a longitudinal sealing seam 14, which extends between the two transverse sealing seams 6 and 7 and realized on the packaging 1 or away from her wegbewegbare fin. By definition, the longitudinal sealing seam 14 is oriented in the longitudinal direction LR of the film 2. The separation zone 26A and also the separation line 26B accordingly run in the transverse direction QR to said longitudinal direction LR.

The longitudinal sealing seam 14 is brought into contact with each other by a first edge zone 15 and a second edge zone 16 (see FIG Fig. 13 ) of the film 2, wherein the first edge zone 15 is bounded by a first film edge 17 and the second edge zone 16 by a second film edge 18 and both edge zones 15 and 16 are oriented in the longitudinal direction LR of the film 2. The two film edges 17 and 18 are congruent in the present case. Thus, different edge zones 15 and 16 of the film 2 are glued together to produce the longitudinal seam 14. In contrast, in the manufacture of the (head-side) first and the (foot-side) second Transverse seam 6 and 7 each two zones of the film 2 abutting each other, which are assigned either a head-side or a foot-side edge of the film 2 or the packaging 1 produced therefrom. Thus, a single edge zone of the film 2 for producing the first transverse seam 6 and a single edge zones of the film 2 for producing the second transverse seam 7 are glued together.

In addition, the packaging 1 in the longitudinal sealing seam 14 has a longitudinal sealing seam opening 19 which is positioned corresponding to the separating zone 26A, in the present case even correspondingly or exactly at the location of the separating line 26B. The longitudinal sealing seam opening 19 has a length of 5 mm. A first distance 20 between the two film edges 17 and 18 and a beginning of the longitudinal seam opening 19 is 2 mm. A second distance 21 between the end of the longitudinal sealing seam opening 19 and one end of the longitudinal sealing seam 14 measured in the transverse direction QR, which corresponds to an angle of 90 ° with respect to the longitudinal direction LR, is 4 mm. Thus, the width of the fin or longitudinal sealing seam 14 has a value of 11 mm. This is also exactly the width of the two edge regions 15 and 16. The longitudinal sealing seam opening 19 is formed as a slot which extends at an angle of 90 ° in the transverse direction QR relative to the longitudinal direction LR of the film 2 in the longitudinal sealing seam 14, or separates them. The longitudinal sealing seam opening 19 is thus eccentrically formed with respect to the center of the longitudinal sealing seam 14 toward the two film edges 17 and 18 offset.

Like in the Fig. 2 is shown, the weakening zone 8 extends along the film 2 from the end of the longitudinal seam opening 19 in the first edge zone 15 to the end of the longitudinal seam opening 19 in the second edge zone 16. The width of the longitudinal seam opening is 0.5 mm.

Also in the presentation of FIG. 2 Both hands 22 and 23 are visible, the package 1 is supported here with both hands 22 and 23 from below. In this view of the package 1, the thumb of the right hand 22 lifts the longitudinal seal 14 slightly upward to better visualize its contours.

By the inventive package 1 is an opening of the package and holding the two pieces of the packaged goods and a removal of the two pieces of the packaged goods without a fouling of the hands 22 and 23 of the user what is possible in the following FIGS. 3 to 12 has been discussed in detail.

In the Fig. 3 the intact longitudinal seal 14 is folded away from the back 12 and shown held with both hands 22 and 23. To open the packaging is first - as in the Fig. 4 illustrated - the outermost region of the longitudinal sealing seam 14 broken. This can be achieved by moving the hands 22 and 23 in the opposite direction parallel to the weakening zone 8 or in the longitudinal direction LR or by a combination of these movements. Thereafter, the two held between the thumb and index finger of the respective hand 22, 23 parts of the longitudinal sealing seam 14 can be easily removed by a pulling movement in which the two hands move away from each other further. As a result, a crack propagating toward the packaged goods 3 forms along the weakening zone 8 in the longitudinal seam 14, which finally arrives at the inner end of the longitudinal seam 14 and destroys the hermetic seal of the pack 1, as described in US Pat Fig. 5 is shown. There are two individually extending cracks, namely a first crack 24, starting from one side of the longitudinal seam 14 and a second crack 25, starting from the second side of the longitudinal seam 14. Continuing the pulling movement then causes a propagation of the two cracks 24 and 25 both sides of the longitudinal seam 14 in the film 2, starting from the broken longitudinal seam 14 along the weakening zone 8 in the adjacent to the longitudinal seam 14 parts of the film 2. Here, the view of the packaged 3 from the back 12 is made possible for the first time, as this in the Fig. 6 is shown.

In a continuation of the pulling movement, the first crack 24 to plant on the right side 5 and it propagates the second crack 25 to over the left side 13 of the package 1, which in the Fig. 7 is shown. From this opening state, the preceding pulling movement can go into a bending movement, as in the Fig. 8 is shown, wherein the two pieces 3A and 3B of Packguts 3 are bent away from each other. Since the weakening zone 8 extends along the separating zone 26, along which the two pieces 3A and 3B are arranged side by side, the two pieces 3A and 3B remain completely undamaged in the buckling movement, they do not fall from the two enclosing parts 1A and 1B of the packaging 1 out because they held there with the hands 22 and 23, and the hands 22 and 23 can hold the respective piece of the packaged goods without coming into contact with it in a clean manner. This is in the Fig. 9 shown in which the bending movement is completed. The two parts 1A and 1B of the package 1 are now connected to each other only along the front side 4 (see in particular Fig. 10 ).

The Fig. 10 shows that the user has turned the package 1 in his hands, so he has overturned. In this holding position, the packaging 1 can be easily separated into its two parts 1A and 1B. For this purpose, the two parts 1A and 1B of the package 1 are simply pulled apart with a pulling movement, which in the Fig. 11 is visualized. This pulling movement is continued until the two cracks 24 and 25 meet. Finally, with each hand 22, 23, the user holds a piece 3A, 3B of the two-piece packaged product 3, which is still packaged with the respective part 1A and 1B of the pack 1. To remove the individual pieces 3A and 3B from their associated parts 1A and 1B of the package 1, only a slight pressure is required from the side of the respective transverse seam 6 or 7, so that the individual pieces 3A and 3B from their parts 1A and 1B the packaging 1 slip out undamaged, which is in the Fig. 12 is shown.

In the Fig. 13 is a synopsis of the views of the package according to the Figures 1 and 2 and a strip of the film 2, which is used for packaging the packaged product 3. By arrows, the individual features of the film 2 can be seen both in the flat spread state and in the state of the produced package 1.

In the first edge zone 15, a first opening 27 and in the second edge zone 16, a second opening 28 is formed. The two openings 27 and 28 are formed at the same distance from the respective film edge 17 and 18 and the respective inner edge of the edge zone 15 and 16 as a slot. Accordingly, the two openings 27 and 28 are formed within their respective edge zones 15 and 16, that the two openings 27 and 28 come to lie completely congruent within the produced longitudinal seam 14 of the package 1 and form said longitudinal sealing seam opening 19 in the same area.

In this illustration, a first transverse edge zones 29 and a second transverse edge zone 30 are visible. The transverse edge zones 29 and 30 are at the Packgut 3 facing inside of the film 2 coated with an adhesive. The first transverse edge zone 29 serves to produce the first transverse sealing seam 6, and the second transverse edge zone 30 serves to produce the second transverse sealing seam 7.

The two openings 27 and 28 are connected by the formed between them formed as a straight line weakening zone 8 in the film 2.

The preparation of the package 1 is below in the Fig. 15 is discussed as a device for packaging the packaged product 3 by means of a highly schematically illustrated horizontal-form-fill-and-seal machine (HFFS machine 31). In this HFFS machine 31 coming from the left, a packaged goods 3 is fed one after the other. Likewise, coming from the left of a roll 32, the film 2 is unwound and fed in its longitudinal direction LR. Clearly highlighted in this illustration, which has no claim to scale fidelity, the openings 27 and 28, and the weakening zone 8. The respective packaged goods 3 is pushed as a unit consisting of the two separate pieces 3A and 3B under the tapered film 2 and in a so-called forming box 34 (also referred to as the envelope and sealing stage, which is designed to produce the longitudinal seam 14), the two film edges 17 and 18 are folded under the packaged 3, so that both edge zones 15 and 16 come to lie looking each other , And finally the adhesive-coated two edge zones 15 and 16 pressed together, so that the longitudinal seam 14 is formed. Furthermore, the generated longitudinal seam 14 between two transport rollers (below the HFFS machine 31 - therefore not visible) continues. In a so-called end sealer 35, the second (foot-side) transverse seam 7 of a first, preceding package 1 is produced in one operation, this package 1 separated from a second, subsequent package 1 and the first (head-side) transverse seal 6 of this subsequent package 1 generated. Thereafter, the separated packages 1 are transported on a conveyor belt 36. The HFFS machine 31 also has so-called film feed rollers 37 for controlled feeding of the film 2 and a packaged goods conveying stage 38 for conveying the packaged product 3.

The individual drives (not shown in detail), for example, the drive for the promotion of the packaged goods 3, for the rotation of the roller 32 for the transport rollers is controlled by a control stage 39. The control stage 39 generates in order Control of said drives Control signals S _i . The control stage 39 also receives sensor signals Pi from the individual sensors (not shown: eg light barriers or cameras for image recognition or sensors for the detection of pressure control marks), so that with the aid of the control stage 39, the film 2 is positioned with respect to the packaged product 3, that the two openings 27 and 28 and the weakening zone 8 corresponding to or within the separation zone 26A is located. Accordingly, the control stage 39, the roller 33 together with the film feed rollers 37, the product conveying stage 38 and the transport rollers, as well as their drives and sensors form a feed system 40, which is designed for said positioning of the film with respect to the packaged goods that an inventive packaged goods 3 packaged with said inventive packaging 1 produced from said film 2 according to the invention is obtained.

Finally, it is pointed out once again that the figures described above in detail are only an exemplary embodiment which can be modified by the person skilled in the art in various ways without departing from the scope of the invention. For the sake of completeness, it is also pointed out that the use of indefinite articles does not exclude "a" or "one", that the characteristics in question can also be present multiple times. Also, individually disclosed features may be combined with other features and proportions of the features illustrated may vary without departing from the concept of the invention.
