Description

Technical Field

[0001] This invention relates to a package filled with a pourable product (particularly a pourable food).

[0002] Furthermore, the present invention also relates to packaging blanks for forming packaging. Background Technology

[0003] As is known, many liquids or pourable foods, such as juice, UHT (ultra-high temperature) milk, wine, and ketchup, are sold in packages made of sterilized packaging materials.

[0004] A typical example is a parallelepiped-shaped package for liquids or pourable foods, called Tetra BrikAseptic (registered trademark), which is made by sealing and folding a laminated packaging preform. The packaging preform has a multi-layered structure, including a fibrous base layer (e.g., paper or cardboard) covered on both sides with a heat-sealable plastic material layer (e.g., polyethylene). For aseptic packaging of long-term storage products (such as UHT milk), the packaging preform also includes an oxygen barrier material layer (oxygen barrier layer, such as aluminum foil) stacked on top of the heat-sealable plastic material layer, and then covered in turn with another heat-sealable plastic material layer, forming the inner surface of the package that ultimately contacts the food.

[0005] This type of packaging is typically produced on fully automated packaging equipment that forms packages from corresponding packaging blanks. These packaging blanks can be provided as individual packaging blanks or as rolls formed from multiple continuously arranged packaging blanks.

[0006] In cases where packaging equipment is designed to form packages from rolls, the packaging equipment advances and sterilizes the roll, then forms the roll into a tube and fills it with a pourable product, and then forms the tube into a separate sealed package.

[0007] It is known to manufacture packages having a bottom wall and a top wall, the bottom wall and the top wall being spaced apart from each other along the longitudinal axis of the package, and a side wall between the top wall and the bottom wall. One variation has the top wall inclined relative to the bottom wall; this type of package is called a package with an inclined top wall. In another variation, the top wall and the bottom wall are parallel to each other.

[0008] It is also known that some packages are provided with an opening device having at least a portion connected to the top wall. The opening device allows control over the outpouring of the pourable product from the package.

[0009] The available space for the opening device is determined by the dimensions of the top wall.

[0010] Despite the excellent results provided by known packaging, further improvements to known packaging are still expected in this field, particularly in order to maximize the available space for the opening device. Summary of the Invention

[0011] One object of the present invention is to provide an improved packaging.

[0012] Another object of the present invention is to provide an improved packaging blank for forming packaging.

[0013] According to the present invention, a package and a packaging blank for forming the package are provided according to the respective independent claims.

[0014] Preferred, non-limiting embodiments of the packaging and the packaging blank are claimed in the corresponding dependent claims. Attached Figure Description

[0015] Four non-limiting embodiments of the invention will be described by way of example with reference to the accompanying drawings, wherein: Figure 1A This is a perspective view of a package filled with a pourable product according to a first embodiment of the present invention; Figure 1B yes Figure 1A Side view of the packaging; Figure 2 It is used to form Figure 1A A plan view of the packaging blank; Figure 3 yes Figure 1A A top view of the packaging; Figure 4 yes Figure 1A Bottom view of the packaging; Figure 5 yes Figure 1A A perspective view of a portion of the packaging; Figure 6 This is a perspective view of a package filled with a pourable product according to a second embodiment of the present invention; Figure 7 It is used to form Figure 6 A plan view of the packaging blank; Figure 8 This is a perspective view of a package filled with a pourable product according to a third embodiment of the present invention; Figure 9 yes Figure 8 A top view of the packaging; Figure 10 It is used to form Figure 8 A plan view of the packaging blank; Figure 11This is a perspective view of a package filled with a pourable product according to a fourth embodiment of the present invention; and Figure 12 It is used to form Figure 11 A plan view of the packaging blank.

[0016] Detailed Implementation Plan Figure 1A Reference numeral 1 in the figure indicates a package filled with a pourable product (preferably a pourable food, such as pasteurized milk, milk, dairy products, drinking yogurt, yogurt drinks, beverages, juices, wine, ketchup, salt, sugar, etc.).

[0017] More specifically, packaging 1 can be formed from packaging blank 2, for example, as Figure 2 As shown.

[0018] More specifically, each package 1 can be formed from a corresponding packaging blank 2 by an automatic packaging machine.

[0019] The automatic packaging machine can be configured to form a package 1 from the corresponding packaging blank 2 and fill the package 1 with the pourable product.

[0020] Preferably, but not necessarily, the packaging blank 2 may have a multi-layer structure.

[0021] More specifically, each packaging blank 2 may include at least one layer of fibrous material (such as a paper or cardboard layer) and at least two heat-sealable plastic material layers (such as polyethylene) sandwiching the fibrous material layer therebetween.

[0022] One of the two heat-sealed plastic material layers can form the inner surface of the corresponding package 1 formed by the corresponding packaging blank 2 and ultimately contact the pourable product.

[0023] Preferably, but not necessarily, each packaging blank 2 may also include a gas and light blocking material layer (e.g., aluminum foil or ethylene vinyl alcohol (EVOH) film), particularly disposed between one of the heat-sealable plastic material layers and the fiber material layer. Preferably, but not necessarily, the packaging blank 2 may also include another heat-sealable plastic material layer between the gas and light blocking material layer and the fiber material layer.

[0024] According to some preferred non-limiting embodiments, the packaging blank 2 can be provided in the form of a roll.

[0025] More specifically, the roll material may be formed from a plurality of continuously arranged packaging blanks 2.

[0026] In other words, the continuously arranged packaging blanks 2 constitute multiple repeating units of the roll material. In particular, each repeating unit (i.e., the corresponding packaging blank 2) forms a precursor of a corresponding package 1.

[0027] Preferably, the packaging machine can be configured to produce packages 1 from the roll material, such that each package 1 is produced from a corresponding packaging blank 2.

[0028] In particular, each packaging blank 2 may include desired patterns / decorations.

[0029] Special Reference Figure 1A The package 1 may extend along the longitudinal axis A, and preferably also along a first transverse axis B perpendicular to the longitudinal axis A and a second transverse axis C perpendicular to the longitudinal axis A and the first transverse axis B.

[0030] Advantageously, the extension (i.e. dimension) of package 1 along the longitudinal axis A can be greater than the corresponding extension (i.e. corresponding dimension) of package 1 along the first transverse axis B and the second transverse axis C.

[0031] For more details, see the reference. Figure 1A , 1B Package 1 may include a bottom wall 3 and a top wall 4 spaced apart from each other along the longitudinal axis A. In particular, the longitudinal axis A is perpendicular to the bottom wall 3.

[0032] In addition, the package 1 may include a side wall 5 extending between the bottom wall 3 and the top wall 4 (and connecting the bottom wall 3 and the top wall 4).

[0033] More specifically, the bottom wall 3 can be defined as a wall of the package 1 having a generally planar shape and being generally perpendicular to the longitudinal axis A. According to some possible non-limiting embodiments, the bottom wall 3 can be configured to be placed on a supporting surface, such as a shelf, refrigerator, table, workbench, etc.

[0034] When the package 1 is placed on the support surface (and in its nominal position, i.e. when used by the user in the intended manner), the bottom wall 3 contacts the support surface, and the top wall 4 maintains a certain distance from the support surface.

[0035] In addition, the side wall 5 may be the part of the packaging 1 that is grasped by the user during the pouring action of the pourable product from the packaging 1.

[0036] According to some possible implementation schemes and such Figure 1A As shown, the top wall 4 can be tilted relative to the bottom wall 3.

[0037] According to some preferred non-limiting embodiments, package 1 may include an opening device (not shown) configured to allow the pourable product to be poured out of package 1.

[0038] More specifically, at least a portion of the opening device may be connected to the top wall 4.

[0039] In more detail, the top wall 4 may include a pouring outlet 6, and the opening device may include an outlet opening aligned with the pouring outlet 6.

[0040] In addition, the opening device may include a collar having the outlet opening, the collar being arranged around the pouring outlet 6.

[0041] Furthermore, the opening device may include a base frame connected to the top wall 4. The collar extends from the base frame.

[0042] According to some possible implementations, the opening device may be connected only to the top wall 4.

[0043] According to some alternative embodiments, a first part of the opening device may be connected to the top wall 4, and a second part of the opening device may be connected to the side wall 5.

[0044] According to some possible implementations, the opening device can be a so-called post-application opening device, meaning that the opening device can be attached (e.g., glued, welded, bonded, etc.) to the top wall 4 after the package 1 is formed.

[0045] According to some alternative embodiments, at least a portion of the opening device may be molded to the top wall 4 and / or the packaging blank 2, particularly before the packaging blank 2 forms the package 1.

[0046] According to other alternative embodiments, the opening device can be reusable. In this embodiment, package 1 is delivered to the consumer without the opening device, and the consumer couples the opening device to the top wall 4 before the first pouring action. Furthermore, the opening device can be removed from the top wall 4 after the pourable product has been used up.

[0047] In further detail, the package 1 may include a longitudinal seam portion, for example, arising from the formation of the package 1 from a tube filled with a pourable product, the tube being longitudinally sealed. Preferably, but not necessarily, the longitudinal seam portion may be substantially parallel to the longitudinal axis A.

[0048] Furthermore, each package 1 may include a first transverse seal and a second transverse seal 9, preferably transverse to the longitudinal axis A. Preferably, the first transverse seal may be included in and / or associated with the bottom wall 3, and the second transverse seal 9 may be included in and / or associated with the top wall 4.

[0049] In more detail, the sidewall 5 may include a front panel 10, a rear panel opposite to the front panel 10, and a plurality of (two in the illustrated example) side panels 12, each side panel 12 being located between the rear panel and the front panel 10.

[0050] During the pouring action, the user's hands (at least when considering the intended use of the package 1) can at least partially contact the rear panel and side panel 12.

[0051] Preferably, the rear panel may include the longitudinal seam portion.

[0052] refer to Figure 1A , 1B And 3 to 5, the top wall 4 includes at least two, more specifically exactly two front corners 15 and at least two, more specifically exactly two rear corners 16.

[0053] More specifically, the rear angle 16 may be spaced apart from the front angle 15, and more specifically, spaced apart along a direction having a component parallel to the first transverse axis B.

[0054] In further detail, the top wall 4 may include a front edge 17 extending between front corners 15, a rear edge 18 extending between rear corners 16, and two side edges 19, each side edge 19 extending between a corresponding pair 20 of a corresponding front corner 15 and a corresponding rear corner 16.

[0055] More specifically, the top wall 4 can be defined by the front edge 17, the rear edge 18 and the side edge 19.

[0056] More specifically, the front edge 17 may extend from one front corner 15 to another front corner 15, and the rear edge 18 may extend from one rear corner 16 to another rear corner 16. In addition, each side edge 19 may extend from a corresponding rear corner 16 to a corresponding front corner 15.

[0057] In further detail, each side edge 19 may contact the front edge 17 at a corresponding front corner 15 of the corresponding pair 20 and the rear edge 18 at a corresponding rear corner 16 of the corresponding pair 20.

[0058] It should be noted that the term "front and back" refers to the nominal use of package 1. For example, if package 1 is used correctly during a pouring action, the rear edge 18 is located between the front edge 17 and the palm of the consumer performing the pouring action.

[0059] In addition, the front panel 10 may include decorations intended to be displayed to consumers at the point of sale.

[0060] In addition, during use, the consumer may place his or her palm near the rear panel during the nominal tilting action.

[0061] according to Figure 1A , 1B In the implementation schemes shown in 3 to 5, the rear edge 18 is farther away from the bottom wall 3 than the front edge 17.

[0062] according to Figure 1A , 1B In the embodiments shown in 3 to 5, the front edge 17 is straight. Alternatively, the front edge 17 may be curved.

[0063] Furthermore, the rear edge 18 is straight. Also, the side edge 19 is straight. Alternatively, one or more of the rear edge 18 and side edge 19 may be curved.

[0064] refer to Figure 4 The bottom wall 3 may include a front bottom edge 21, a rear bottom edge 22, and two bottom side edges 23.

[0065] Each bottom edge 23 may contact the bottom front edge 21 at the corresponding bottom front corner 24 and the bottom rear edge 22 at the corresponding bottom rear corner 25.

[0066] According to the illustrated embodiment, the bottom wall 3 may have a (substantially) rectangular shape, i.e., each bottom edge 23 is orthogonal to the bottom front edge 21 and bottom rear edge 22, and the bottom front edge 21 and bottom rear edge 22 may be parallel to each other.

[0067] Advantageously, the front panel 10 may extend from the front edge 17 to the bottom front edge 21, and the rear panel may extend from the rear edge 18 to the bottom rear edge 22.

[0068] like Figure 1A and 5 As shown, the corresponding interface between each side panel 12 and the front panel 10 can constitute a corresponding auxiliary panel. The corresponding interface can have various shapes, such as curved, straight, etc.

[0069] Furthermore, the corresponding interfaces of the same package 1 can be different from each other.

[0070] Furthermore, as Figure 1B and 3 As shown, the projection of the top wall 4 onto a plane P perpendicular to the longitudinal axis A produces a corresponding front angle 27 and a corresponding back angle 28, specifically corresponding to the corresponding front angle 15 and the corresponding back angle 16. In other words, the front angle 27 is the projection of the front angle 15 onto plane P and the back angle 28 is the projection of the back angle 16 onto plane P.

[0071] In particular, Figure 3 Note the top view and plane P of package 1, where each front corner 15 is superimposed on the corresponding projected front corner 27 and each rear corner 16 is superimposed on the corresponding projected rear corner 28.

[0072] Special Reference Figure 3 The imaginary front line 30 extends through the front angle of the projection 27 and the imaginary back line 31 extends through the back angle of the projection 28.

[0073] Advantageously, a corresponding imaginary lateral line 32 extends through each pair of corresponding projected anterior angles 27 and corresponding projected posterior angles 28, which correspond to the projections of the corresponding anterior angle 15 and corresponding posterior angle 16 of a (i.e., the same) corresponding lateral edge 19 onto plane P.

[0074] In particular, the imaginary front line 30, the imaginary rear line 31, and each imaginary flank line 32 have corresponding straight line shapes.

[0075] according to Figure 3 In the example shown, a portion of the imaginary front line 30 corresponds to the corresponding projection of the front edge 17 onto plane P, and a portion of the imaginary rear line 31 corresponds to the corresponding projection of the rear edge 18 onto plane P. Furthermore, a corresponding portion of each imaginary side line 32 corresponds to the projection of the corresponding side edge 19 onto plane P.

[0076] In addition, according to Figure 1A , 1B In embodiments 3 to 5, a corresponding first angle α is defined between the imaginary rear line 31 and each imaginary lateral line 32. Advantageously, at least one first angle α, and in the specific case shown, all first angles α, are equal to 90°.

[0077] Advantageously, a corresponding second angle β is defined between the imaginary front line 30 and each imaginary flank line 32. Advantageously, at least one second angle β, and in the specific case shown, all second angles β, are equal to 90°.

[0078] Furthermore, since each imaginary side line 32 includes a portion corresponding to the projection of the corresponding side edge 19 onto the plane P, each first angle α and each second angle β defined with reference to the corresponding imaginary side line 32 corresponds to an angle defined with respect to the projection of the corresponding side edge 19.

[0079] It should be noted that each first angle α and / or each second angle β is measured in a portion of plane P defined by the projection of the top wall 4 onto plane P.

[0080] Each first angle α is measured by keeping the imaginary backline 31 fixed relative to the portion of the plane P and rotating the corresponding imaginary lateral line 32 around the corresponding projected back angle 28 within the portion of the plane P until the corresponding imaginary lateral line 32 is superimposed on the imaginary backline 31.

[0081] Similarly, each second angle β is measured by keeping the imaginary front line 30 fixed relative to the portion of the plane P and rotating the corresponding imaginary lateral line 32 within the portion of the plane P about the corresponding projected front angle 27 until the corresponding imaginary lateral line 32 is superimposed on the imaginary front line 30.

[0082] This also means that when considering the orientation of packaging 1 (from the consumer's perspective) such that the front edge 17 is between the consumer and the rear edge 18, the imaginary side line 32 arranged on the left moves counterclockwise to determine the corresponding first angle α, and the imaginary side line 32 arranged on the right moves clockwise to determine the corresponding first angle α. Additionally, the imaginary side line 32 arranged on the left moves clockwise to determine the corresponding second angle β, and the imaginary side line 32 arranged on the right moves counterclockwise to determine the corresponding second angle β.

[0083] Special Reference Figure 3 A first distance d1 is defined between the imaginary back line 31 and the imaginary front line 30, and a second distance d2 is defined between the projected front angles 27.

[0084] More specifically, the first distance d1 is defined relative to a direction parallel to the first horizontal axis B.

[0085] In addition, the second distance d2 can be defined relative to a direction parallel to the second horizontal axis C.

[0086] Generally, when the imaginary backline 31 and the imaginary frontline 30 are not parallel to each other, the first distance d1 corresponds to the maximum distance between a portion of the imaginary backline 31 defined between the projection back angles 28 and a portion of the imaginary frontline 30 defined between the projection front angles 27.

[0087] Advantageously, the first distance d1 is greater than the second distance d2.

[0088] In this way, the available space for opening the device is maximized.

[0089] According to the example shown, the second distance d2 corresponds to the distance between the front corners 15.

[0090] In addition, since the first distance d1 is greater than the second distance d2, the distance between the front edge 17 and the back edge 18 is also greater than the second distance d2.

[0091] According to the example shown, the distance between the front edge 17 and the back edge 18 is greater than the first distance d1.

[0092] according to Figure 1A , 1B In the implementation schemes shown in 3 to 5, the hypothetical lateral lines 32 are parallel to each other.

[0093] In addition, the hypothetical front line 30 and the hypothetical rear line 31 are parallel to each other.

[0094] Special Reference Figure 3 A third distance d3 is defined between the projection back angle 16.

[0095] More specifically, the third distance d3 can be determined along a direction parallel to the second horizontal axis C.

[0096] according to Figure 1A , 1B In the implementation schemes shown in 3 to 5, the third distance d3 is equal to the second distance d2.

[0097] According to some preferred non-limiting embodiments, at least a portion of the opening device may be located between the transverse seal 9 and the front edge 17. More specifically, no portion of the opening device may be located between the transverse seal 9 and the rear edge 18.

[0098] Special Reference Figure 1A Package 1 may include flaps 33 attached to and / or extending from top wall 4.

[0099] Figure 2 The packaging blank 2 is designed to allow the formation of packaging 1.

[0100] More specifically, each packaging blank 2 may include: Two longitudinal boundary edges, preferably a first longitudinal boundary edge 40 and a second longitudinal boundary edge 41, are spaced apart from each other along a first principal direction M1 that is transverse to the longitudinal axis E of the packaging blank 2 and preferably perpendicular to the longitudinal axis E of the packaging blank 2; and The two transverse boundary edges, preferably the first transverse boundary edge 42 and the second transverse boundary edge 43, are spaced apart from each other along the second principal direction M2, which is parallel to the longitudinal axis E and / or transverse to, preferably perpendicular to, the first principal direction M1 and / or transverse to, preferably perpendicular to, the transverse axis F of the corresponding packaging blank 2.

[0101] Preferably, the horizontal axis F can be perpendicular to the vertical axis E.

[0102] Preferably, the vertical axis E intersects the horizontal axis F at the center point of the packaging blank 2.

[0103] More specifically, each packaging blank 2 can extend in a plane stretched by the longitudinal axis E and the transverse axis F.

[0104] Furthermore, each packaging blank 2 may have a (substantially) two-dimensional shape, meaning that the corresponding extensions (i.e., dimensions) of each packaging blank 2 along the longitudinal axis E and the transverse axis F may (significantly) be greater than the thickness of the packaging blank 2. In other words, the thickness of the packaging blank 2 is negligible compared to the corresponding extensions (i.e., corresponding dimensions) of the packaging blank 2 along the longitudinal axis E and the transverse axis F.

[0105] Preferably, each packaging blank 2 may have a rectangular or square shape.

[0106] In addition, the first principal direction M1 can be parallel to the horizontal axis F.

[0107] In addition, the second principal direction M2 can be parallel to the longitudinal axis E.

[0108] Furthermore, each first longitudinal boundary edge 40 and each second longitudinal boundary edge 41 may be connected to and between a corresponding first transverse boundary edge 42 and a corresponding second transverse boundary edge 43.

[0109] Preferably, each first longitudinal boundary edge 40 and each second longitudinal boundary edge 41 may be arranged at an angle of approximately 90° relative to the corresponding first transverse boundary edge 42 and the corresponding second transverse boundary edge 43.

[0110] It should be noted that when each packaging blank 2 is arranged separately, i.e. separated from other packaging blanks 2, the corresponding first longitudinal boundary edge 40, the corresponding second longitudinal boundary edge 41, the corresponding first transverse boundary edge 42 and the corresponding second transverse boundary edge 43 can be actual edges.

[0111] When the packaging blank 2 is arranged in roll form, the corresponding first longitudinal boundary edge 40 and the corresponding second longitudinal boundary edge 41 can be actual edges, and the corresponding first transverse boundary edge 42 and the corresponding second transverse boundary edge 43 can be imaginary edges. In particular, each first transverse boundary edge 42 of one packaging blank 2 may be adjacent to or coincide with the corresponding second transverse boundary edge 43 of another packaging blank 2.

[0112] Alternatively, the corresponding first lateral boundary edge 42 and the corresponding second lateral boundary edge 43 can be actual edges, and the corresponding first longitudinal boundary edge 40 and the corresponding second longitudinal boundary edge 41 can be imaginary edges. In particular, each first longitudinal boundary edge 40 of one packaging blank 2 may be adjacent to or coincide with the corresponding second longitudinal boundary edge 41 of another packaging blank 2.

[0113] Special Reference Figure 2 Each packaging blank 2 may include a top segment having a top crease pattern 44 configured to define at least a top wall 4.

[0114] More specifically, the top crease pattern 44 can be configured to define the top wall 4 and the wing 33.

[0115] Preferably, the packaging blank 2 may also include a bottom segment having a bottom crease pattern 45 configured to define at least a bottom wall 3.

[0116] More specifically, the bottom crease pattern 45 can be configured to define the bottom wall 3 and the wing (not shown) attached to the bottom wall 3.

[0117] In addition, the top and bottom segments can be spaced apart from each other along the longitudinal axis E.

[0118] Additionally, the packaging blank 2 also includes a middle section having a middle crease pattern 46 located between the top crease pattern 44 and the bottom crease pattern 45 and configured to form the sidewall 5. In particular, the middle section may be located between the top section and the bottom section.

[0119] More specifically, the center crease pattern 46 may define the front panel 10, the rear panel, and the side panel 12.

[0120] It should be noted that the top crease pattern 44, the bottom crease pattern 45, and the middle crease pattern 46 define corresponding sections of the top wall 4, the bottom wall 3, and the side wall 5. Therefore, in the following text, we will use the same terminology and the same reference numerals for the features of the packaging blank 2 and the packaging 1, where deemed appropriate.

[0121] Special Reference Figure 2 Each top crease pattern 44 may include at least one first transverse crease line 47 extending transversely to the longitudinal axis E.

[0122] Additionally, the bottom crease pattern 45 may include at least one second transverse crease line 48 extending transversely to the longitudinal axis E.

[0123] Furthermore, the first transverse crease line 47 and the second transverse crease line 48 can be displaced relative to each other along the second principal direction M2.

[0124] More specifically, the first transverse crease line 47 and the second transverse crease line 48 together define the middle section.

[0125] More specifically, the top crease pattern 44 may include a third transverse crease line 49 that is displaced along the second main direction M2 from the first transverse crease line 47 and lies between the first transverse boundary edge 42 and the first transverse crease line 47 along the second main direction M2.

[0126] Additionally, the bottom crease pattern 45 may include a fourth transverse crease line 50 that is displaced along the second main direction M2 from the second transverse crease line 48 and lies between the second transverse boundary edge 43 and the second transverse crease line 48 along the second main direction M2.

[0127] according to Figure 2 In the example shown, the second horizontal crease line 48 may have a straight shape.

[0128] More details and references Figure 2 The top crease pattern 44 may include a plurality of top crease lines that define and / or determine the shape of the top wall 4.

[0129] In particular, at least some of the top crease lines may be designed to define and / or define the front edge 17, the rear edge 18, and the side edges 19 (after the packaging 1 is formed from the packaging blank 2). Additionally, at least some of the top crease lines may define and / or define the front corner 15 and the rear corner 16.

[0130] More specifically, the bottom crease pattern 45 may include a plurality of bottom crease lines that define and / or determine the shape of the bottom wall 3.

[0131] In particular, at least some bottom crease lines may be designed to define and / or define the front bottom edge 21, the rear bottom edge 22, and the side bottom edge 23 (after the packaging 1 is formed from the packaging blank 2). Additionally, at least some bottom crease lines may define and / or define the front bottom corner 24 and the rear bottom corner 25.

[0132] In particular, the top crease line can be arranged to obtain the top wall 4 as described above, and accordingly, to obtain the top wall 4 having the above-described relationship between the imaginary front line 30, the imaginary rear line 31, and the imaginary side line 32.

[0133] According to some non-limiting embodiments, the first lateral crease line 47 may include a front portion 54 designed to form and / or define the front edge 17. Additionally, the first lateral crease line 47 may include one or more rear portions 55 designed to form and / or define the rear edge 18.

[0134] More specifically, the first part 54 may be located between the two second parts 55.

[0135] Additionally, the top crease pattern 44 may also include a plurality of lateral crease lines 56 designed to form and / or define the side edges 19.

[0136] More specifically, the lateral crease 56 may extend between the first transverse crease 47 and the third transverse crease 49.

[0137] Furthermore, the lateral crease lines 56 can be displaced relative to each other along the first principal direction M1.

[0138] Additionally, the top crease pattern 44, particularly the first transverse crease line 47, may include a plurality of auxiliary crease lines 57, each auxiliary crease line 57 situated between a corresponding rear portion 55 and a front portion 54. In particular, each auxiliary crease line 57 may be generated after the packaging blank 2 is formed into the packaging 1, i.e., forming or defining a corresponding side edge 19.

[0139] according to Figure 2 In the implementation scheme, the auxiliary crease line 57 can be tilted relative to the rear portion 55 and the front portion 54.

[0140] According to some advantageous embodiments, each auxiliary crease line 57 and / or its corresponding imaginary extension may include a corresponding front intersection point 58 and a corresponding rear intersection point 59. In particular, each auxiliary crease line 57 may intersect the front portion 54 and / or its corresponding imaginary extension at the corresponding front intersection point 58 and intersect a corresponding rear portion 55 and / or its corresponding imaginary extension at the corresponding rear intersection point 59.

[0141] According to some advantageous implementation schemes, after the packaging blank 2 is formed into the corresponding package 1, each front intersection 58 corresponds to a corresponding front angle 15 and each rear intersection 59 corresponds to a corresponding rear angle 16.

[0142] According to some preferred non-limiting embodiments, a fourth distance d4 is defined between the first intersection points 58.

[0143] Additionally, a fifth distance d5 is defined between each front intersection 58 and the corresponding projected back intersection 70, the projected back intersection corresponding to the projection of the corresponding back intersection 59 onto the imaginary line 61 extending through the front intersection 58 (along the longitudinal axis E). In other words, d5 is defined between the projections of each front intersection 58 and the corresponding back intersection 59 onto the imaginary line 61 along the longitudinal axis E, the back intersection belonging to the same auxiliary crease line 57 and / or its corresponding imaginary extension.

[0144] Advantageously, the fourth distance d4 is less than the fifth distance d5.

[0145] According to the embodiment shown, the extension (i.e., dimension) of the front portion 54 corresponds to the fourth distance d4.

[0146] Alternatively, the front portion 54 lies between but does not extend to the front intersection 58. According to this alternative embodiment, the extension (i.e., dimension) of the front portion 54 is shorter than the fourth distance d4.

[0147] According to the illustrated implementation, the distance between each front intersection 58 and the corresponding rear intersection 59 is greater than the fifth distance d5. In particular, the corresponding extension (i.e., corresponding dimension) of each auxiliary crease line 57 is greater than the fifth distance d5.

[0148] According to the non-limiting example shown, each of the two lateral crease lines 56 and / or its corresponding imaginary extension may intersect the first transverse crease line 47 and / or its corresponding imaginary extension at the respective anterior intersection point 58.

[0150] According to some possible non-limiting embodiments, each lateral crease line 56 is configured to cooperate with a corresponding other lateral crease line 56 to define and / or define a corresponding side edge 19.

[0151] According to such Figure 2 Some possible implementations shown include each lateral crease line 56 which may be orthogonal to the third transverse crease line 49 and / or the front portion 54 and / or the rear portion 55.

[0152] according to Figure 2 In the embodiment shown, each lateral crease line 56 may be (substantially) parallel to the first longitudinal boundary edge 40 and the second longitudinal boundary edge 41.

[0155] Preferably, but not necessarily, the top crease pattern 44 may include the main panel 60, preferably having and / or carrying at least a portion of the designated pouring opening area 6.

[0156] More specifically, the main panel 60 may be defined by an imaginary line 61, a defining portion 62 of a third lateral crease line 49 and / or a corresponding imaginary extension line facing and parallel to the imaginary line 61, and two corresponding lateral crease lines 56 and / or their corresponding imaginary extension lines.

[0157] More specifically, the defining portion 62 extends between two intermediate intersection points 63. Each intermediate intersection point 63 is defined by the intersection of a corresponding lateral crease line 56 and / or its corresponding imaginary extension with a third transverse crease line 49 and / or its corresponding imaginary extension.

[0158] Advantageously, the shape of the main panel 60 corresponds to a rectangle.

[0159] According to some possible implementations, a third angle γ is defined between the front portion 54 and / or its corresponding imaginary extension line and each of the lateral crease line 56 and / or its corresponding imaginary extension line.

[0160] The angle γ is limited within 60 degrees on the main panel.

[0161] Additionally, a fourth angle δ is defined between each of the rear portions 55 and / or their respective imaginary extensions and each of the lateral crease lines 56 and / or their respective imaginary extensions.

[0162] Angle δ is defined on the opposite side of the auxiliary crease line 57 relative to the lateral crease line 56.

[0163] according to Figure 2 In the embodiment shown, the third angle γ and / or the fourth angle δ are equal to 90°.

[0164] It should be noted that each third angle γ is determined in the plane of the packaging blank 2, that is, the third angle γ is measured by keeping the corresponding lateral crease line 56 fixed relative to the plane and moving the front part 54 angularly in the plane until the front part 54 overlaps the corresponding lateral crease line 56.

[0165] Similarly, each fourth angle δ is determined in the plane of the packaging blank 2, that is, each fourth angle δ is measured by keeping the corresponding lateral crease line 56 fixed relative to the plane and moving the rear portion 55 angularly in the plane until the rear portion 55 overlaps the corresponding lateral crease line 56.

[0166] According to some examples not shown, the packaging blank 2 may include at least a portion of an opening device connected (e.g., molded or glued) to the packaging blank 2 and surrounding a designated pouring opening area 6.

[0167] Special Reference Figure 2 The bottom crease pattern 45 may include multiple crease lines configured to define and / or define the bottom front edge 21, bottom rear edge 22 and bottom side edge 23 and / or bottom front corner 24 and bottom rear corner 25.

[0168] In particular, the aforementioned crease lines are designed such that the bottom wall 3 has a rectangular shape after the packaging 1 is formed.

[0169] According to some possible non-limiting embodiments, some or all of the hypothetical extensions are linear hypothetical extensions.

[0170] In particular, the linear extension line of the front part 54 is a linear imaginary extension line, and / or the linear extension line of the rear part 55 is a linear imaginary extension line, and / or the linear extension line of the lateral crease line 56 is a linear imaginary extension line, and / or the linear extension line of the auxiliary crease line 57 is a linear imaginary extension line.

[0173] Therefore, the first distance d1 corresponds to the distance between the corresponding front angle 15 and the corresponding rear angle 16 of each pair 20. The first distance d1 also corresponds to the distance between the front edge 17 and the rear edge 18.

[0174] In particular, each projected front angle 27 coincides with the corresponding front angle 15 and each projected rear angle 28 coincides with the corresponding rear angle 16.

[0195] The difference between package 1''' and package 1'' is that the top wall 4 is (basically) parallel to the bottom wall 3.

[0196] Therefore, the first distance d1 corresponds to the distance between the corresponding front angle 15 and the corresponding rear angle 16 of each pair 20. The first distance d1 also corresponds to the distance between the front edge 17 and the rear edge 18.
