Description

Technical Field

[0001] The present invention relates in particular to a packaging blank for forming a package having a multilayer structure and filled with a pourable food product, in particular.

[0002] Advantageously, the present invention also relates to a package formed from a packaging blank and filled with a pourable product such as a pourable food product.

Background Art

[0003] As is well known, many liquids or pourable food products such as fruit juices, UHT (ultra-high temperature sterilized) milk, wine, tomato sauce, etc. are sold in packages made of sterilized packaging materials.

[0004] As a typical example, there is a rectangular parallelepiped package for a liquid or pourable food product known as Tetra Brik Aseptic (registered trademark). This is made by sealing and folding a laminated packaging blank. The packaging blank has a multilayer structure in which, for example, a fibrous base material layer of paper or cardboard is covered on both sides with a heat-sealing plastic material layer such as polyethylene. In the case of a sterile package for a long-term storage product such as UHT milk, the packaging blank further includes a layer of an oxygen barrier material (oxygen barrier layer), for example an aluminum foil, which is laid on top of the heat-sealing plastic material layer and is further covered with another heat-sealing plastic material layer that forms the inner surface of the package that finally comes into contact with the food.

[0005] This type of package is usually manufactured by a fully automatic packaging device that forms the package from the packaging blank. These packaging blanks are supplied in the form of a single packaging blank or in a web form including a plurality of packaging blanks arranged in succession.

[0006] If the packaging machine is designed to form packages from a web, the machine feeds out the web, sterilizes it, then forms it into a tube, fills it with a dispenseable product, and then forms the tube into individual sealed packages.

[0007] To facilitate package formation and define the shape, the packaging blank is provided with multiple fold lines.

[0008] Typically, a packaging blank is rectangular and defined by a first longitudinal boundary, a second longitudinal boundary, a first transverse boundary, and a second transverse boundary.

[0009] A typical packaging blank comprises an upper fold pattern configured to form the top of the package and a bottom fold pattern configured to form the bottom of the package. The upper fold pattern includes at least a first transverse fold line and a second transverse fold line, and the bottom fold pattern includes at least a third transverse fold line and a fourth transverse fold line.

[0010] It is known to manufacture packages having a bottom wall and a top wall spaced apart from each other along the longitudinal axis of the package. As a variation, the top wall is inclined relative to the bottom wall, and such packages are known as packages with an inclined top wall.

[0011] Such packages are known to be manufactured from packaging blanks having an appropriate top fold pattern. The top fold pattern includes a first transverse fold line and a second transverse fold line, as well as a number of auxiliary fold lines and bevel fold lines that intersect the first and second transverse fold lines. [Overview of the project] [Problems that the invention aims to solve]

[0012] While packages formed from such packaging blanks yield excellent results, there is a demand in the industry for further improvements to these packaging blanks. [Means for solving the problem]

[0013] Therefore, the object of the present invention is to provide an improved packaging blank.

[0014] Another object of the present invention is to provide an improved package formed from a packaging blank.

[0022] The automatic packaging machine is configured to form the packages 1 from the respective packaging blanks 2 and fill the packages 1 with a pourable product, in particular a pourable food product (for example, pasteurized milk, fruit juice, wine, tomato sauce, etc.).

[0023] Preferably, the packaging blank 2 may have a multilayer structure.

[0024] More specifically, each packaging blank 2 may include at least one layer of a fibrous material such as a paper or cardboard layer, and at least two layers of a heat-sealable plastic material such as polyethylene, and these layers may be configured to sandwich the layer of the fibrous material between them.

[0025] One of these two layers of heat-sealable plastic material may form the inner surface of each package 1 formed from the respective packaging blank 2 and finally contact the pourable product to be poured.

[0026] Preferably, the packaging blank 2 further includes a layer of a gas- and light-blocking material (for example, an aluminum foil or an ethylene vinyl alcohol (EVOH) film), and in particular, it may be disposed between one of the layers of the heat-sealable plastic material and the layer of the fibrous material. Preferably, but not necessarily, the packaging blank 2 may include a further layer of a heat-sealable plastic material intervening between the layer of the gas- and light-blocking material and the layer of the fibrous material.

[0027] According to some preferred non-limiting embodiments, the packaging blank 2 may be provided in the form of a web.

[0028] More specifically, the web may be formed from a plurality of packaging blanks 2 arranged in sequence.

[0029] In other words, the consecutively arranged packaging blanks 2 define multiple repeating units of the web. In particular, each repeating unit (i.e., each packaging blank 2) forms a precursor to package 1.

In other words, the thickness of the packaging blank 2 may be negligibly small compared to each extension along the longitudinal axis B and transverse axis C.

[0112] Referring to Figure 4, number 2' shows another embodiment of the packaging blank according to the present invention. Since packaging blank 2' is the same as packaging blank 2, the following description will be limited to the differences between the two, and the same reference numerals will be used wherever possible for identical or corresponding parts.

[0113] In particular, packaging blank 2' differs from packaging blank 2 in that the main inclined fold line 27 does not intersect with the first transverse fold line 16.

[0118] Clearly, modifications may be made to packaging blanks 2 and 2' described herein, without departing from the scope of protection defined in the appended claims.
