DESCRIPTION OF PREFERRED EMBODIMENTS

[0051] Referring now to the drawings wherein the showings are for the purpose of illustrating preferred and alternative embodiments of the invention only and not for the purpose of limiting the same, in FIG. 1, an embodiment first according to the invention of a push-through cover foil is labelled generally by 10. FIG. 1 shows the cover foil 10 in a top view with a plurality of linear material weakenings 12 each of the same length and same orientation. The material weakenings 12 are arranged behind each other in parallel lines 16 with breaks 14. The breaks 14 of different lines 16 are arranged offset relative to one another, such that when proceeding from a break 14 from a starting line 16 orthogonally to an adjacent line 16, one does not encounter a break 14 in the adjacent line 16 but a material weakening 12.

[0052] Since the offsetting of breaks 14 between two parallel lines 16 is preferably of the same magnitude across all pairwise adjacent lines, this yields parallel rows 18 each of which contains material weakenings 12 parallel to one another. Since the first embodiment of the push-through cover foil 10 exhibits only a single type of material weakening 12, all of which are directionally aligned and exhibit the same length, for one thing each row 18 comprises only material weakenings 12 parallel to one another, and for another the material weakenings 12 of one row 18 are likewise parallel to the material weakenings 12 of an adjacent row 18.

[0053] The rows 18 extend along a row length direction RL and exhibit a row width RB which is orthogonal to the row length direction RL. The material weakenings 12 which are parallel to one another of a row 18 are tilted by an angle α with respect to a line parallel to the row width RB. The angle α can be negative, as in the case of the embodiment of FIG. 1. In fact only its magnitude is important.

[0054] The row width RB equals in the present case the running length (see running length VL in FIGS. 2 and 3) multiplied by the cosine of the angle α. Accordingly, the row spacing RD between two immediately adjacent rows 18 which is orthogonal to the row length direction RL equals the running length of the break 14 along a line 16 multiplied by the cosine of the angle α.

[0055] The material weakenings 12 parallel to one another of a row 18 are separated from one another within the row 18 by a weakening spacing SA to be measured along the row length direction RL. Although not absolutely necessary, nevertheless it is preferable for the weakening spacing SA to be constant along the row length direction RL.

[0056] The machine direction MD, along which a material web of the cover foil runs through the machine fabricating it, can be oriented arbitrarily relative to the rows 18 or relative to the lines 16, as the case may be. An example is shown in FIG. 1. The lines 16 are tilted in the depicted embodiment example by 10° with respect to the machine direction MD. This value is given merely as an example.

[0057] In FIG. 1 the running length of the straight material weakenings 12 is preferably between 3 and 6 mm, especially preferably between 4.5 and 5.5 mm, and most preferably about 5 mm.

[0058] The breaks 14 configured between two immediately adjacent material weakenings 12 in the direction of a line 16, in which the material cohesion of the cover foil 10 is not weakened, exhibit a length in the direction of the line 16 of preferably 5% to 15%, especially preferably of 8% to 12%, most preferably of 10%, of the running length of the material weakenings 12. In absolute terms, the break 14 can have a length of between 0.3 and 0.9 mm in the direction of the line 16, preferably of 0.4 to 0.6 mm, and especially preferably of 0.5 mm.

[0059] The weakening spacing SA can be chosen arbitrarily, in the present case it can for example lie between 40% and 60% of the running length of the straight material weakenings 12. Expressed in absolute terms, the weakening spacing SA can preferably lie between 1.2 and 3.6 mm, especially preferably between 1.8 and 3.3 mm, and especially preferably between 2.4 and 3 mm.

[0060] The material weakenings 12 of the first embodiment can be introduced thermally and/or mechanically as the case may be by means of laser beams or by means of a bladed drum, starting from an exposed surface of the cover foil 10, in its depth direction which is orthogonal to the drawing plane of FIG. 1.

[0061] In FIG. 2 there is shown a second embodiment of a push-through cover foil. Identical and functionally identical components and component sections as in the first embodiment are labelled in the second embodiment by the same reference symbols but increased numerically by 100. The second embodiment is described below only in so far as it differs from the first embodiment, to the description of which reference is otherwise made for elucidating the second embodiment also.

[0062] In contrast to the first embodiment, in the push-through cover foil 110 of FIG. 2 there is introduced not only a single type of material weakenings 112 into the cover foil 110 but beyond that a second type of material weakenings 120. The material weakenings 112 are therefore referred to below as first material weakenings 112 and the material weakenings 120 are referred to below as second material weakenings 120.

[0063] The depth direction of the cover foil 110 proceeds as in the first embodiment 10 of FIG. 1 orthogonally to the drawing plane of its depiction, i.e. here of FIG. 2. The machine direction MD is once again shown in FIG. 2 by way of example, but it can proceed in an arbitrary other direction and can in particular be rotated by 45° or by 30°, by 60°, or by other angles with respect to a rotation axis orthogonal to the drawing plane of FIG. 2, in order to mention only a few prominent running directions of a possible machine direction MD when fabricating the cover foil 110.

[0064] The embodiment of FIG. 2 allows the identification of different rows with first material weakenings 112 parallel to one another and second material weakenings 120 parallel to one another, respectively.

[0065] For a start, in FIG. 2 there alternate only first and second material weakenings 112 and 120 respectively in a machine transverse direction CD which is orthogonal to the machine direction MD and parallel to the drawing plane of FIG. 2. Consequently the pattern of material weakenings 112 and 120 of the cover foil 110 exhibits rows 118 proceeding in the machine transverse direction CD, which exhibit along their row length direction RL-118 alternately a first material weakening 112 and a second material weakening 120. Since the weakening spacing SA is respectively the spacing between two first material weakenings 112 parallel to one another or between two second material weakenings 120 parallel to one another, the weakening spacing SA-118 of the rows 118 is comparatively large. Of the rows 118, where only two rows 118 are emphasized through dotted boxes by way of example, each row 118 thus contains both types of first material weakenings 112 parallel to one another and second material weakenings 120 parallel to one another.

[0066] In the depicted example, both material weakenings 112 and 120 each exhibit the same running length VL, where the first material weakenings 112 are tilted by an angle α with respect to the direction of the row width RB-118 of the rows 118, which in the depicted example differs in magnitude from the angle α of FIG. 1. The tilt of the second material weakenings 120 with respect to the row width RB-118 is equal in magnitude but exhibits the opposite tilt direction to the tilt of the first material weakenings 112. The second material weakenings 120 are therefore tilted by the angle −α with respect to the row width RB-118. The row width RB-118 therefore again corresponds to the running length of the material weakenings 112 and 120, multiplied by the cosine of the angle α.

[0067] As in the example of the first embodiment, in the second embodiment too the individual material weakenings 112 and 120 do not intersect.

[0068] In addition, it is possible to define in the cover foil 110 parallel first rows 122 and parallel second rows 124 proceeding in the machine direction MD which differ from the aforementioned rows 118 by the first rows 122 each containing only first material weakenings 112 parallel to one another and the second rows 124 each containing only second material weakenings 120 parallel to one another. In the present example, the possible parallel rows 118 on the one hand and the parallel first rows 122 and second rows 124 on the other are rotated by 90° relative to one another. This, however, need not be the case. Given appropriate offset of the material weakenings 112 and 120 in adjacent first and second rows 122 and 124 respectively along the common row length direction RL-122 and RL-124 respectively, the rows 118 on the one hand and the parallel first rows 122 and second rows 124 on the other can enclose an angle which differs from 90° but also from 0°. This will be further demonstrated below by reference to the third embodiment of FIG. 3.

[0069] Relative to the likewise common row widths RB-122 and RB-124, the material weakenings 112 and 120 are tilted by an angle β or −β respectively, where due to the previously described relative position of the rows 118 on the one hand and of the rows 122 and 124 on the other, β=90°−α. Accordingly, the common row widths RB-122 and RB-124 correspond in magnitude to the common running length VL of the material weakenings 112 and 120, multiplied either by the cosine of the angle β or by the sine of the angle α.

[0070] Reading from top to bottom, there exists between a first row 122 and a second row 124 immediately adjacent to it a row spacing RD-122 and there exists between a second row 124 and a first row 122 immediately adjacent to it a row spacing RD-124. In the depicted example, the row spacings RD-122 and RD-124 are equal in size.

[0071] Because of the use of only equal first material weakenings 122 on the one hand and only equal second material weakenings 120 on the other, the weakening spacing SA-122 which is the same size for both rows 122 and 124 is shorter than the weakening spacing SA-118 of rows 118.

[0072] The dimensions shown in FIG. 2 can, without limitation, lie in the following ranges or have the following values, respectively: The running length VL of the material weakenings 112 and 120 can for example have a dimension of 1 to 3 mm, preferably of 1.5 to 2.5 mm, and especially preferably of 2 mm.

[0073] The row spacing RD-122 and/or RD 124 respectively can have a value of 0.5 to 1 mm, preferably of 0.65 to 0.8 mm and especially preferably of 0.7 mm.

[0074] The weakening spacing SA-122 and/or SA-124 respectively can have a value of 1 to 3 mm, preferably a value of 1.2 to 2.5 mm, especially preferably of 1.5 to 2 mm.

[0075] The weakening spacing SA-118 can have a value of 3.5 to 6 mm, preferably of 4.5 to 5.5 mm, especially preferably of 4.7 to 5 mm.

[0076] The row spacing RD-118 lies preferably in the ranges quoted above for the row spacings RD-122 and RD 124.

[0077] The magnitude of the angle β lies preferably in a range of 20° to 40°, especially preferably in a range of 25° to 35°, and most preferably at 30°. The magnitude of the angle α is obtained from the angle β, in that α and β sum up to 90°.

[0078] In FIG. 3 there is depicted a third embodiment of a push-through cover foil 210. Identical and functionally identical components and component sections as in FIGS. 1 and 2 are labelled by the same reference symbols but in the numerical range from 200 to 299. The third embodiment of FIG. 3 is described only in so far as it differs from the previously described embodiments of FIGS. 1 and 2, to the description of which reference is otherwise made for elucidating the embodiment of FIG. 3.

[0079] The embodiment of the cover foil 210 also exhibits two different types of material weakenings, namely first material weakenings 212 and second material weakenings 220, but in a different spatial distribution than the cover foil 110 of the second embodiment. On the cover foil 210 there are arranged one after another material weakenings in two different spatial directions, which here by way of example and fortuitously correspond to the machine direction MD and the machine transverse direction CD, where unlike the second embodiment of the cover foil 110, in each of these spatial directions first material weakenings 212 and second material weakenings 220 are arranged and configured alternately one after another.

[0080] Consequently there is identifiable on the cover foil 210 a first row 218 with material weakenings parallel to one another, which contains both first material weakenings 212 and second material weakenings 220, or contains only the aforementioned material weakenings as the case may be, and which essentially corresponds to the row 118 of the cover foil 110. The row length direction RL-218 of the first row 218 is parallel to the machine transverse direction CD. To the first row 218 there is adjacent with a row spacing RD-218 a second row 219, which is a mirror image of the first row 118 with respect to a mirror-symmetry axis which is parallel to the row length direction RL-218. In other words, the second row 219 corresponds to the first row 218 which is offset by one material weakening along the row length direction RL-218. The rows 218 and 219 alternate in a sequential direction orthogonally to their parallel row length directions RL-218 and RL-219.

[0081] To the first row 218 there applies correspondingly what was said about the first row 118 of the second embodiment. To the second row 219 there applies correspondingly what was said about the first row 118 of the second embodiment under the mirror-symmetry condition described above. The matching row width RB-218 and RB-219 of the two rows 218 and 219 respectively equals in each case the running length VL, which in the depicted example is the same size for the first material weakenings 212 and the second material weakenings 220, multiplied by the cosine of the angle α or −α, which however is the same factor.

[0082] Orthogonally to the first row 218 and to the second row 219 it is possible to define a third row 221 and a fourth row 223. Basically, the third row 221 corresponds to the first row 122 of the second embodiment with the proviso that each second first material weakening 112 is replaced by a second material weakening 220. Likewise, basically the fourth row 223 corresponds to the second row 124 of the second embodiment with the proviso that each second second material weakening 120 is replaced by a first material weakening 212. The designation third row and fourth row serves merely for differentiation. The row 221 could just as appropriately be designated as second first row 221 and the fourth row 223 could be designated as second second row 223.

[0083] The third and the fourth row 221 and 223 are mirror-symmetrical to each other with respect to a mirror-symmetry axis parallel to the parallel row length directions RL-221 and RL-223. Once again, the fourth row 223 can be regarded as a third row 221 offset by one material weakening in the row length direction RL-221 .

[0084] The equal row widths RB-221 and RB-223 correspond in magnitude to the matching running length VL of the first material weakening 212 and the second material weakening 220, multiplied by the sine of the angle α or −α, which however is the same factor.

[0085] Orthogonally to the row length directions RL-221 and RL-223 there follow one another alternately third rows 221 and fourth rows 223, where the row spacings RD-221 between third and fourth rows and the row spacings RD-223 between fourth and third rows are equal in magnitude.

[0086] In the third embodiment too, there can be defined rows which exhibit only first material weakenings 212 and only second material weakenings 220. These proceed obliquely with respect to the aforementioned rows 218 and 219 or 221 and 223, as the case may be.

[0087] A fifth row or better: a third first row 222 contains—like the row 122 of the second embodiment—only first material weakenings 212. A sixth or better: third second row 224 parallel to the fifth row 222 contains—like the row 124 of the second embodiment—only second material weakenings 220.

[0088] Orthogonally to the parallel row length directions RL-222 and RL-224 there follow alternately fifth rows 222 and sixth rows 224, each with equal in magnitude row spacings RD-222 between fifth and sixth rows and RD-224 between sixth and fifth rows.

[0089] The first material weakenings 212 are tilted by an angle β with respect to the direction of the row width RB-222 of the fifth (or the third first, as the case may be) row 222. The second material weakenings 212 are tilted by an angle γ with respect to the direction of the row width RB-224 of the sixth (or the third second, as the case may be) row 224, where unlike the second embodiment the angle γ in the third embodiment differs in magnitude from the angle β, even differs considerably. Therefore, the row widths RB-222 on the one hand and RB-224 on the other are different, in particular considerably different, due to the very different cosines of the angle β on the one hand and y on the other.

[0090] Due to the overall symmetrical arrangement of the first material weakenings 212 and the second material weakenings 220, as manifested first and foremost by the two mirror-symmetrical row pairs 218 and 219 on the one hand 221 and 223 on the other, the weakening spacings SA-122 on the one hand and SA-224 on the other are equal in size in the depicted example.

[0091] The individual dimensions can have the following value ranges: The row spacings RD-218 and RD-219 can have a value in a range from 0.5 to 1.5 mm, preferably from 0.7 to 1.3 mm, especially preferably from 1 mm. The row spacings RD-218 and RD-219 do not have to be equal in size, but preferably are.

[0092] The row widths RB-218 and RB-219 lie preferably between 0.6 and 2 mm, especially preferably between 0.9 and 1.7 mm, and most preferably between 1.1 and 1.4 mm.

[0093] The angle α is between 40° and 80°, preferably between 50° and 70°, especially preferably 60°.

[0094] The row spacings RD-221 and RD-223 can have a value in a range from 0.3 to 1.2 mm, preferably from 0.5 to 0.9 mm, especially preferably from 0.7 mm. The row spacings RD-221 and RD-223 do not have to be equal in size, but preferably are.

[0095] The weakening spacings SA-218 and SA-219 can lie in a range from 4.5 to 6.5 mm, preferably from 5.2 to 6 mm, especially preferably from 5.65 to 5.8 mm. The weakening spacings SA-218 and SA-219 do not have to be equal in size, but preferably are.

[0096] The weakening spacings SA-221 and SA-223 can lie in a range from 3.5 to 6 mm, preferably from 3.9 to 5 mm, especially preferably from 4.35 to 4.6 mm. The weakening spacings SA-221 and SA-223 do not have to be equal in size, but preferably are.

[0097] The row width RB-222 lies preferably between 1.6 and 3 mm, especially preferably between 1.8 and 2.6 mm and especially preferably between 2.1 and 2.35 mm.

[0098] The row width RB-224 lies preferably between 0.1 and 0.6 mm, especially preferably between 0.2 and 0.5 mm and especially preferably between 0.3 and 0.4 mm.

[0099] The weakening spacings SA-222 and SA-222 can lie in a range from 2.7 to 4.2 mm, preferably from 3.1 to 3.8 mm, especially preferably from 3.25 to 3.4 mm. The weakening spacings SA-221 and SA-223 do not have to be equal in size, but preferably are.

[0100] The running length VL of the first and the second material weakenings 212 and 220 respectively lies preferably between 1.5 and 3 mm, especially preferably between 1.8 and 2.7 mm, and most preferably between 2 and 2.5 mm.

[0101] The angle β lies preferably between 10° and 40°, especially preferably between 20° and 30°, most preferably 25°.

[0102] The angle γ lies preferably between 60° and 85°, especially preferably between 70° and 85°, most preferably between 80° and 83°.

[0103] In FIG. 4, which is not to scale, there is depicted in rough schematic form a section of a first embodiment of a push-through pack 30 according to the invention. It comprises a container component 32, in which an accommodation volume 34 is configured in which a product 36, for example a tablet, is accommodated. The accommodation volume 34 is accessible through an aperture 38, which is sealed by an embodiment of a push-through cover foil according to the invention, for instance the push-through cover foil 10.

[0104] In the depicted example, the cover foil 10 is a polymer mono-foil 40 which in order to facilitate recycling of the entire push-through pack 30 is made from the same polymer as the container component 32. The polymer can be polyethylene terephthalate or a polyolefin, in particular polypropylene. Especially preferably, the polymer is a monoaxially or biaxially oriented or stretched polymer as the case may be, such as for example oPet, MOPP or BOPP.

[0105] On the side of the polymer mono-foil 40 facing towards the container component 32 there is applied in the depicted example a ceramic barrier layer 42, for example made from aluminum oxide and/or silicon oxide. This should hamper the migration of water vapor and oxygen from the external environment into the accommodation volume 34.

[0106] On the side of the barrier layer 42 facing away from the polymer mono-foil 40 and facing towards the container component 32 there is applied a sealing layer 44, for example made from a polyolefin, with which the cover foil 10 is firmly sealed with the container component 32 in order to close the aperture 38 securely.

[0107] The dashed line 46 indicates the end of the material weakenings which are introduced from the side of the polymer mono-foil 40 facing away from the container component 32 in the depth direction T into the polymer mono-foil 40. The material weakenings do not completely penetrate through the polymer mono-foil 40 in the thickness direction, such that a rest of the polymer mono-foil 40 and above all the barrier layer 42 remains uncompromised by the material weakenings and intact.

[0108] Onto the side of the polymer mono-foil 40 facing away from the container component 32 there can be applied an applied printed layer 48, multilayer where relevant, including a protective varnish layer, in order to convey product data to the consumer. Alternatively, the polymer mono-foil 40 can also be printed in reverse printing, where the applied printed layer then cannot form the outermost layer but rather there has to be applied between it and the container component 32 the sealing layer 44 or another adhesive layer, such as for example a cement layer.

[0109] In the embodiment example of FIG. 4, the applied printed layer 48 can cover the material weakenings from outside, such that for the consumer these are initially neither visible nor palpable. Since, however, the applied printed layer 48 cannot accommodate especially large tensions and forces, the applied printed layer 48 does not hinder pushing through of the cover foil 10 through deformation of the container component 32 in the region of the accommodation volume 34 under force transmission through the product 36.

[0110] In FIG. 5 there is depicted a second embodiment of a push-through pack according to the invention, again not to scale.

[0111] Identical and functionally identical components and component sections as in FIG. 4 are labelled in FIG. 5 by the same reference symbols, but increased numerically by 100. The cover foil can therefore be the cover foil 110 from FIG. 2.

[0112] The second embodiment of FIG. 5 is described below only in so far as it differs from the first embodiment of FIG. 4, to the description of which reference is otherwise made for elucidating the second embodiment of FIG. 5 also.

[0113] The container component 132 is the same container component as in the first embodiment, likewise the product 136 packaged in the push-through pack 130.

[0114] In contrast to the first embodiment, in the cover foil 110 the material weakenings are introduced from the side of the sealing layer 144 in the thickness direction into the cover foil 110. Therefore, for one thing the dashed line 146, which indicates the end of the material weakenings in the polymer mono-foil 140, lies nearer to the outer surface of the polymer mono-foil 140 facing away from the container component 132, and therefore for another the barrier layer 142 is applied on the outer surface of the polymer mono-foil 140 facing away from the container component 132 in order to prevent reliably compromising the barrier layer 142 by the introduction of material weakenings into the cover foil 110.

[0115] The barrier layer 142 can be a ceramic barrier layer as in in the first embodiment or vapor-deposited metallizing.

[0116] On the outer side of the barrier layer 142 pointing away from the polymer mono-foil 140 and from the container component 132 there can again be applied an applied printed layer 148, multilayer where relevant.

[0117] The cover foil 210 of FIG. 3 forms, through the mutually orthogonal arrangement regions 218, 219 on the one hand and 221, 223 on the other, an orthogonal arrangement pattern of the material weakenings 212 and 220.

[0118] In many or even most cases, the accommodation volumes in a container component are also arranged in an orthogonal pattern. Since a container component preferably exhibits only one and the same product packaged in its accommodation volumes, the accommodation volumes of a container component are preferably configured with the same size and with the same shape.

[0119] An especially advantageous effect with a low push-through force needed for local pushing through the cover foil 210 of FIG. 3, is achieved when the orthogonal arrangement pattern defined on the cover foil 210 is rotated by an angle of 30° to 60°, preferably by an angle of 40° to 50°, especially preferably by 45° with respect to an orthogonal grid of the accommodation volumes in the container component.

[0120] While considerable emphasis has been placed on the preferred embodiments of the invention illustrated and described herein, it will be appreciated that other embodiments, and equivalences thereof, can be made and that many changes can be made in the preferred embodiments without departing from the principles of the invention. Furthermore, the embodiments described above can be combined to form yet other embodiments of the invention of this application. Accordingly, it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
