Description

Technical Field

[0001] This invention relates to packaging for pourable products (especially pourable food). Background Technology

[0002] As is well known, many liquid or pourable foods (such as fruit juice, UHT (ultra-high temperature) milk, wine, ketchup, etc.) are sold in packages made of sterilized packaging materials.

[0003] A typical example is the parallelepiped-shaped packaging for liquids or pourable foods, known as Tetra Pak Aseptic Packaging (a registered trademark), which is made by sealing and folding a preform. This preform has a multi-layered structure, including a fibrous base layer (e.g., paper or cardboard) covered on both sides by heat-sealable plastic material layers (e.g., polyethylene). For aseptic packaging of products intended for long-term storage (e.g., UHT milk), the preform also includes an oxygen barrier layer (oxygen barrier layer), such as aluminum foil, stacked on top of the heat-sealable plastic material layers and itself covered by another heat-sealable plastic material layer, forming the inner surface of the packaging that ultimately contacts the food.

[0004] This type of packaging is typically produced on fully automated packaging equipment, which forms packages from corresponding packaging blanks. These packaging blanks can be provided as individual packaging blanks or as webs formed from multiple packaging blanks arranged in succession.

[0005] In cases where packaging equipment is designed to form packages from webs, the equipment advances and sterilizes the webs; then the webs are formed into tubes, the tubes are filled with pourable products, and the tubes are then formed into individual sealed packages.

[0006] It is known to produce packaging having a bottom wall and a top wall spaced apart from each other along the longitudinal axis of the packaging, and having a side wall between the top and bottom walls. In one variation, the top wall is inclined relative to the bottom wall. This type of packaging is called packaging with an inclined top wall. In another variation, the top and bottom walls are parallel to each other.

[0007] It is also known that some packaging is designed to allow consumption on the go, in other words, packaging designed so that consumers can consume the product directly from the packaging.

[0008] Some packaging has a designated pouring opening and an associated opening device. In order to consume the product, the consumer needs to operate the opening device to expose the designated pouring opening.

[0009] Despite the excellent results provided by known packaging, further improvements to known packaging are still desired in the art. Summary of the Invention

[0010] The purpose of this invention is to provide an improved packaging.

[0011] According to the present invention, a package as described in the independent claim is provided.

Detailed Implementation

[0014] The elements and features shown in the various preferred embodiments (including the accompanying drawings) may be combined with each other without departing from the scope of protection of this application as described below.

[0015] Figure 1 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, drinkable yogurt, yogurt drinks, beverages, fruit juice, wine, ketchup, salt, sugar, etc.

[0016] More specifically, package 1 may be made of, for example... Figure 4 The packaging blank 2 shown is formed.

[0017] More specifically, each package 1 can be formed from a corresponding package blank 2 by means of an automatic packaging machine.

[0018] An automatic packaging machine can be configured to form a package 1 from corresponding packaging blanks 2 and fill the package 1 with a pourable product.

[0019] Preferably, but not necessarily, the packaging blank 2 may have a multi-layer structure.

[0020] More specifically, each packaging blank 2 may include at least one layer of fibrous material (e.g., a paper layer or a cardboard layer) and at least two layers of heat-sealable plastic material (e.g., polyethylene), wherein the at least two layers of heat-sealable plastic material sandwich the fibrous material layer between each other.

[0021] One of these two heat-sealing plastic material layers can form the inner surface of the corresponding package 1 formed from the corresponding packaging blank 2, and ultimately come into contact with the pourable product.

[0022] 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), which is disposed, in particular, between a heat-sealable plastic material layer and a fiber material layer. Preferably, but not necessarily, the packaging blank 2 may also include another heat-sealable plastic material layer, which is located between the gas and light blocking material layer and the fiber material layer.

[0023] Packaging blank 2 can be provided in the form of a web.

[0024] More specifically, the web can be formed from multiple continuously arranged packaging blanks 2.

[0025] In other words, the continuously arranged packaging blanks 2 constitute multiple repeating units of the web. Specifically, each repeating unit (i.e., the corresponding packaging blank 2) forms a precursor of a corresponding package 1.

[0026] Preferably, the packaging machine can be configured to produce packages 1 from webs, such that each package 1 is obtained from a corresponding package blank 2.

[0027] In particular, each packaging blank 2 may include desired patterns / decorations.

[0028] Alternatively, each package blank 2 can be provided as a single package blank.

[0029] Special reference Figure 1 The packaging 1 can extend along the longitudinal axis A, and preferably also along the first transverse axis B and the second transverse axis C, wherein the first transverse axis B is perpendicular to the longitudinal axis A, and the second transverse axis C is perpendicular to the longitudinal axis A and the first transverse axis B.

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

[0031] Packaging 1 can be configured for consumption on the go, i.e., packaging 1 can be designed for consumption of the pourable product directly from packaging 1.

[0032] For more details and reference Figure 1 and Figure 2 The package 1 may include a bottom wall 3 and a top wall 4, which are spaced apart from each other along a longitudinal axis A.

[0033] Specifically, the longitudinal axis A is perpendicular to the bottom wall 3.

[0034] Additionally, the package 1 may include a side wall 5 that extends between the bottom wall 3 and the top wall 4 (and connects to the bottom wall 3 and the top wall 4).

[0035] More specifically, the bottom wall 3 can be defined as a wall of the package 1 that is substantially planar in shape and substantially perpendicular to the longitudinal axis A.

[0036] The bottom wall 3 can be configured to be placed on a support surface, such as a shelf, refrigerator, table, workbench, etc.

[0037] When the package 1 is placed on the support surface (and in its nominal position, i.e. when the user uses the package 1 in the intended manner), the bottom wall 3 is in contact with the support surface, and the top wall 4 is at a certain distance from the support surface.

[0038] Additionally, the sidewall 5 may be the part of the packaging 1 that is held by the user during the user's action of pouring the pourable product from the packaging 1 and / or consuming the pourable product.

[0039] The bottom wall 3, top wall 4, and side walls 5 constitute the main body of the packaging 1. In particular, the main body is formed of multiple layers of packaging material, especially of corresponding blanks 2.

[0040] like Figure 1 As shown, the top wall 4 is inclined relative to the bottom wall 3.

[0041] Package 1 may include a designated pouring opening, which is at least partially disposed on the top wall 4 and configured to allow pourable products to be poured out of package 1.

[0042] The designated pouring opening may be covered by the separation membrane of package 1. In particular, the separation membrane needs to be removed before the first pouring action.

[0043] The separation membrane may be composed of a portion of the packaging material, particularly a portion of a layer of the packaging material that is different from the fibrous material layer.

[0044] Package 1 may also include an opening device 6 configured to open a designated pouring opening.

[0045] When the designated pouring opening is covered by the separation membrane, the opening device 6 can be connected to the separation membrane, for example, by fusion or bonding.

[0046] In addition, the opening device 6 is configured to be torn, detached, or pulled off by the consumer from the designated pouring opening in order to obtain the contents of the package 1.

[0047] Reference Figure 1 and Figure 2 The opening device can be a peeling foil or pull tab that covers a designated pouring opening and can be removed from the designated pouring opening, particularly by tearing.

[0048] In addition, the peeling foil 6 or the pull sheet can be fused to the separation membrane, or can form the separation membrane.

[0049] Additionally, the interior of the package 1 can be accessed by removing the peeling foil 6 or pull tab from the designated pouring opening.

[0050] Once the peeling foil 6 or pull tab is removed from the designated pouring opening, the consumer can drink directly from the package 1.

[0051] The peelable foil 6 or pull sheet may include a first portion and a second portion connected to the first portion. The first portion is attached to the package 1, and the second portion is initially connected to and covers the designated pouring opening.

[0052] Once the second part is removed from the designated pouring opening, the first part remains connected to package 1. In particular, the second part remains connected to package 1 via the first part after being removed from the designated pouring opening.

[0053] Alternatively, the opening device may include a tearing element, which is molded onto the package 1, and more particularly onto the package blank 2 prior to the formation of the package 1. Access to the interior of the package 1 can be obtained by removing the tearing element from a designated pouring opening.

[0054] Once the element is torn open and removed from the designated pouring opening, the consumer can drink directly from package 1.

[0055] The opening device may include a base and a cover portion, the cover portion defining a tear-off element and being attached to the base. The base is attached to the package 1, and the cover portion is initially attached to and covers a designated pouring opening.

[0056] Once the cover portion (i.e., the tear element) is removed from the designated pouring opening, the base remains attached to the package 1. In particular, the cover portion (i.e., the tear element) remains attached to the package 1 via the base after being removed from the designated pouring opening.

[0057] More specifically, the package 1 may include a longitudinal seam portion 7, for example, formed by a tube filled with a pourable product and having a longitudinal seal. Preferably, but not necessarily, the longitudinal seam portion 7 may be substantially parallel to the longitudinal axis A.

[0058] Additionally, each package 1 may include a bottom transverse sealing strip and a top transverse sealing strip 9, which are preferably transverse to the longitudinal axis A. Preferably, the bottom transverse sealing strip may be contained in and / or associated with the bottom wall 3, and the top transverse sealing strip 9 may be contained in and / or associated with the top wall 4.

[0059] More specifically, the sidewall 5 may include a front panel 10, a rear panel 11 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 11 and the front panel 10 and connected to the rear panel 11 and the front panel 10.

[0060] Preferably, but not necessarily, the rear panel 11 may include a longitudinal seam portion 7.

[0061] Reference Figure 1 and Figure 2 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.

[0062] 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 second transverse axis C.

[0063] More specifically, 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 angle pair 20 of a corresponding front corner 15 and a corresponding rear corner 16.

[0064] More specifically, the top wall 4 can be defined by the front edge 17, the rear edge 18 and the side edge 19.

[0065] More specifically, the front edge 17 may extend from one front corner 15 to the other front corner 15, and the rear edge 18 may extend from one rear corner 16 to the other rear corner 16. Additionally, each side edge 19 may extend from a corresponding rear corner 16 to a corresponding front corner 15.

[0066] More specifically, each side edge 19 may contact the front edge 17 at the corresponding front angle 15 of the corresponding angle pair 20 and the rear edge 18 at the corresponding rear angle 16 of the corresponding angle pair 20.

[0067] It should be noted that the terms "front" and "rear" refer to the nominal use of packaging 1. For example, if packaging 1 is used correctly during a pouring action, the rear edge 18 is located between the front edge 17 and the fingers (excluding the thumb) of the consumer performing the pouring action, which are in contact with packaging 1.

[0068] Additionally, the front panel 10 may include decorations intended to be exposed to consumers at the point of sale.

[0069] Additionally, during use, during the nominal tipping action, the consumer's palm can face the rear panel 11 or one of the side panels 12.

[0070] according to Figure 1 and Figure 2 In the illustrated embodiment, the front edge 17 is straight. Alternatively, the front edge 17 may be curved.

[0071] Additionally, the rear edge 18 is straight. Furthermore, the side edge 19 is straight. Alternatively, one or more of the rear edge 18 and side edges 19 may be curved.

[0072] Reference Figure 1 , Figure 2 As shown in Figure 3, the bottom wall 3 may include a bottom front edge 21, a bottom rear edge, and two bottom side edges 23.

[0073] Advantageously, the longitudinal joint portion 7 extends at least between the rear edge 18 and the bottom rear edge. In particular, the longitudinal joint portion 7 extends on the top wall 4, the bottom wall 3, and between the rear edge 18 and the bottom rear edge.

[0074] Advantageously, the front edge 17 has no longitudinal seam portion 7. In other words, the longitudinal seam portion 7 does not contact the front edge 17 (and does not intersect with the front edge 17). More advantageously, the bottom front edge 21 also has no longitudinal seam portion 7. In other words, the longitudinal seam portion 7 does not contact the bottom front edge 21 (and does not intersect with the bottom front edge 21).

[0075] Each bottom front edge 21 may extend between two bottom front corners 24, each bottom rear edge may extend between two bottom rear corners 25, and each bottom side edge 23 may contact the bottom front edge 21 at the corresponding bottom front corner 24 and contact the bottom rear edge at the corresponding bottom rear corner 25.

[0076] According to the illustrated embodiment, the bottom wall 3 may have a (substantially) rectangular shape, i.e., each bottom side edge 23 is orthogonal to the bottom front edge 21 and the bottom rear edge, and the bottom front edge 21 and the bottom rear edge may be parallel to each other.

[0077] Advantageously, the front panel 10 may extend from the front edge 17 to the bottom front edge 21, and the rear panel 11 may extend from the rear edge 18 to the bottom rear edge.

[0078] like Figure 1 As shown, at least a portion of the opening device and / or at least a portion of the designated pouring opening may be located between the top transverse sealing strip 9 and the front edge 17. More specifically, no portion of the opening device and / or any portion of the designated pouring opening may be present between the top transverse sealing strip 9 and the rear edge 18.

[0079] Advantageously, the top transverse sealing strip 9 is folded on the top wall 4 toward the rear edge 18.

[0080] Advantageously, the top transverse sealing strip 9 is folded on the top wall 4 toward the rear corner 16.

[0081] In addition, the opening device 6 and / or the designated pouring opening are closer to the front edge 17 than the rear edge 18.

[0082] Additionally, the opening device 6 and / or the designated tipping opening are closer to the front panel 10 than the rear panel 11.

[0083] Special reference Figure 1 The top wall 4 has a rectangular shape.

[0084] Special reference Figures 1 to 3B The first imaginary plane P1 includes the bottom front edge 21 and the bottom rear edge.

[0085] Alternatively or additionally, the first imaginary plane P1 includes a bottom front corner 24 and a bottom rear corner 25.

[0086] In addition, the second imaginary plane P2 includes a front edge 17 and a rear edge 18.

[0087] Alternatively or additionally, the second imaginary plane P2 includes a front angle 15 and a rear angle 16.

[0088] Special reference Figure 3B The first imaginary plane P1 and the second imaginary plane P2 intersect at the imaginary intersection line 30.

[0089] It should be noted that Figure 3A and Figure 3B The construction of the first imaginary plane P1 and the second imaginary plane P2 and their intersection are schematically shown. Figure 3A The construction of the first imaginary plane P1 and the second imaginary plane P2 is highlighted, while Figure 3B The intersection of the first imaginary plane P1 and the second imaginary plane P2 is highlighted. For simplicity, Figure 3A The first imaginary plane P1 and the second imaginary plane P2 are omitted from the text.

[0090] In addition, the first imaginary plane P1 and the second imaginary plane P2 define an acute angle α, which is in particular greater than 0° and less than 90°.

[0091] Furthermore, the intersecting plane S includes an imaginary intersection line 30 and is perpendicular to the first imaginary plane P1.

[0092] The rear edge 18 lies between the front edge 17 and the intersecting plane S.

[0093] Additionally, the bottom rear corner 25 is located between the bottom front corner 24 and the imaginary intersection line 30.

[0094] In addition, the rear panel 11 is located between the front panel 10 and the intersecting plane S.

[0095] More specifically, the first distance d1 from the front edge 17 to the first imaginary plane P1 is greater than the second distance d2 from the rear edge 18 to the first imaginary plane P1, especially when measured along a reference axis perpendicular to the first imaginary plane P1, and even more particularly when measured along the longitudinal axis A.

[0096] In addition, the bottom wall 3 is (basically) located in the first imaginary plane, and the top wall 4 is (basically) located in the second imaginary plane P2.

[0097] Special reference Figure 1 Package 1 may include folding wings 31 attached to and / or extending from top wall 4.

[0098] Figure 4 The packaging blank 2 is designed to allow the formation of packaging 1.

[0099] More specifically, each package 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, which is transverse (preferably perpendicular) to the longitudinal axis E of the packaging blank 2; and - Two transverse boundary edges, preferably a first transverse boundary edge 42 and a second transverse boundary edge 43, are spaced apart from each other along a second principal direction M2, which is parallel to the longitudinal axis E and / or transverse (preferably perpendicular to) the first principal direction M1 and / or transverse (preferably perpendicular to) the transverse axis F of the corresponding packaging blank 2.

[0100] Preferably, the transverse axis F can be perpendicular to the longitudinal axis E.

[0101] Preferably, the longitudinal axis E intersects the transverse axis F at the center point of the packaging blank 2.

[0102] More specifically, each packaging blank 2 can extend in a plane stretched by the longitudinal axis E and the transverse axis F.

[0103] 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 be (significantly) larger 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.

[0104] Preferably, each packaging blank 2 may have a rectangular or square shape.

[0105] In addition, the first principal direction M1 can be parallel to the transverse axis F.

[0106] In addition, the second principal direction M2 can be parallel to the longitudinal axis E.

[0107] Furthermore, each first longitudinal boundary edge 40 and each second longitudinal boundary edge 41 can be connected to a corresponding first transverse boundary edge 42 and a corresponding second transverse boundary edge 43, and are located between the corresponding first transverse boundary edge 42 and the corresponding second transverse boundary edge 43.

[0108] 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.

[0109] 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 real edges.

[0110] When the packaging blanks 2 are arranged in the form of webs, the corresponding first longitudinal boundary edge 40 and the corresponding second longitudinal boundary edge 41 can be real edges, while 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 can be adjacent to or coincide with the corresponding second transverse boundary edge 43 of another packaging blank 2.

[0111] Alternatively, the corresponding first lateral boundary edge 42 and the corresponding second lateral boundary edge 43 can be real edges, while 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 can be adjacent to or coincide with the corresponding second longitudinal boundary edge 41 of another packaging blank 2.

[0112] Special reference Figure 4 Each packaging blank 2 may include a top section having a top crease pattern 44 configured to define at least a top wall 4 (e.g., a rectangular or trapezoidal shape).

[0113] More specifically, the top crease pattern 44 can be configured to define the top wall 4 and the fold 31.

[0114] Preferably, the packaging blank 2 may further include a bottom section having a bottom crease pattern 45 configured to define at least the shape of the bottom wall 3 (e.g., a rectangular shape).

[0115] More specifically, the bottom crease pattern 45 can be configured to define the bottom wall 3 and the folds (not shown) attached to the bottom wall 3.

[0116] In addition, the top section and the bottom section can be spaced apart from each other along the longitudinal axis E.

[0117] Additionally, the packaging blank 2 also includes a middle section having a middle crease pattern 46 between the top crease pattern 44 and the bottom crease pattern 45 and configured to define the sidewall 5. Specifically, the middle section may be located between the top section and the bottom section.

[0118] according to Figure 4 In the example shown, the middle crease pattern 46 has no crease lines.

[0119] More specifically, the central crease pattern 46 may define the front panel 10, the rear panel 11, 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 portions 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 4 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 may be offset from each other along the second main 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, which is offset relative to the first transverse crease line 47, particularly offset along the second principal direction M2, and is located between the first transverse boundary edge 42 and the first transverse crease line 47 along the second principal direction M2.

[0126] Specifically, the first horizontal crease 47 is located between the third horizontal crease 49 and the second horizontal crease 48.

[0127] Additionally, the bottom crease pattern 45 may include a fourth transverse crease line 50, which is offset relative to the second transverse crease line 48 along the second main direction M2 and is located between the second transverse boundary edge 43 and the second transverse crease line 48 along the second main direction M2.

[0128] according to Figure 4 In the example shown, the second lateral crease line 48 and / or the fourth lateral crease line 50 may have a straight shape.

[0129] For more details and reference Figure 4 The top crease pattern 44 may include multiple top crease lines that define and / or determine the shape of the top wall 4.

[0130] Specifically, at least some of the top crease lines may be designed to define and / or determine the front edge 17, the rear edge 18, and the side edges 19 after the packaging blank 2 is formed into the packaging 1. In addition, at least some of the top crease lines may define and / or determine the front corner 15 and the rear corner 16.

[0131] In further detail, the bottom crease pattern 45 may include multiple bottom crease lines that define and / or determine the shape of the bottom wall 3.

[0132] Specifically, at least some bottom crease lines may be designed to define and / or determine the bottom front edge 21, bottom rear edge, and bottom side edge 23 after the packaging blank 2 is formed into the packaging 1. In addition, at least some bottom crease lines may define and / or determine the bottom front corner 24 and bottom rear corner 25.

[0133] Specifically, the top crease line can be arranged to obtain the top wall 4 as described above.

[0134] According to some non-limiting embodiments, the first lateral crease 47 may include a front portion 54 designed to define and / or define the front edge 17. Additionally, the first lateral crease 47 may include one or more rear portions 55 designed to define and / or define the rear edge 18.

[0135] More specifically, the first part 54 may be located between the two second parts 55.

[0136] Additionally, the top crease pattern 44 may also include multiple lateral crease lines 56 designed to define and / or define the side edges 19.

[0137] Therefore, the front portion 54, the rear portion 55, and the side crease line 56 may define at least some of the top crease lines.

[0138] More specifically, each lateral crease line 56 may be configured to mate with another lateral crease line 56 in order to define and / or define a corresponding side edge 19.

[0139] More specifically, the lateral crease 56 may extend between the first transverse crease 47 and the third transverse crease 49.

[0140] Furthermore, the lateral crease lines 56 can be offset from each other along the first main direction M1.

[0141] Additionally, the top crease pattern 44 (particularly the first transverse crease line 47) may include a plurality of auxiliary crease portions 57, each auxiliary crease portion 57 being located between a corresponding rear portion 55 and a front portion 54. In particular, each auxiliary crease portion 57 may create (i.e. define or define) a corresponding side edge 19 after the packaging blank 2 is formed into the packaging 1.
