Packaging item and packaged food product

Description

1 / 59 PACKAGING ITEM AND PACKAGED FOOD PRODUCT FIELD OF THE INVENTION

[001] The invention relates to a packaging item and a packaged food product. BACKGROUND OF THE INVENTION

[002] Packaging items for packing various types of contents are provided in a variety of different shapes, sizes, and materials. For example, packaging items made of paper are known in the prior art and are often promoted as being environmentally friendly and more sustainable, for example, compared to plastic.

[003] However, existing packaging items made of paper often do not provide the same protection of the contents, for example, compared with other materials such as plastic or glass. This can adversely affect one or more properties of the contents, for example, which may result in a reduced shelf life of the contents.

[004] Typically, oxidation and / or the influx of moisture from the packaged contents leads to the degradation of the organoleptic properties of said product, which is, naturally, undesirable. In some cases, food safety may be compromised by the transfer of gases and / or moisture through the packaging walls. Therefore, it is of utmost importance, at least with sensitive food products, to ensure a packaging barrier against gases – particularly oxygen – and moisture.

[005] Furthermore, existing packaging items made of paper often suffer from reduced structural stability compared to packaging items made of other materials, for example, plastic or glass. This can adversely affect the handling properties of the packaging items. Petition 870250094163, dated 10 / 15 / 2025, page 10 / 89 2 / 59

[006] US patent application 2017 / 0057687 A1 by Borer et al. discloses a container comprising an inner sleeve and an outer sleeve capable of sliding into one another to open and close the container. The inner sleeve is printed with various materials, and the outer sleeve comprises an opening forming a window such that when the inner and outer sleeves are moved relative to each other, the material printed on the inner sleeve is revealed. The container disclosed therein may be made of any type of material, such as cardboard, but it does not disclose a solution for preserving the contents against oxygen or moisture interactions. On the contrary, the open reading window in the outer sleeve significantly reduces the possibilities of securely protecting the contents when the container is closed.Furthermore, the container assembly provides little resistance to vertical stacking due to the fact that, in its vertical stacked position, the compressive forces applied to the container are supported only by the inner sleeve.

[007] US patent application 2011 / 0204015 A1 by West et al. discloses a biodegradable jar with a lid. The jar walls are made of a permeation barrier material that prevents the semi-solid contents from seeping through the jar walls, but does not provide a barrier against oxygen and moisture transfer, especially after the first opening (the so-called shelf life): with the US'015 construction, it is necessary to apply a complex capping solution to ensure an adequate moisture and oxygen barrier at the interface between the jar and the lid. Furthermore, the container has moderate resistance to vertical stacking because, in its vertical stacked position, the compressive forces are supported only by the jar walls.

[008] US document 2377471 is a US patent by Wil Petition 870250094163, dated 10 / 15 / 2025, page 11 / 89 Figure 3 / 59 reveals a classic box-type container comprising a dispensing opening located in one of its side panels. The container is an assembly of individual elements, each of which is formed from a flat, raw block (blank). This provides little barrier to oxygen and moisture, particularly after the box has been opened and used for the first time, and has moderate resistance to stacking.

[009] Therefore, particularly in view of the disadvantages identified above, it is an objective of the present invention to provide a packaging item that provides greater protection to the contents within the packaging item. It is a further objective of the present invention to provide a packaging item with improved handling properties and mechanical strength. Solution to the problem

[0010] In a first aspect, the present invention relates to a packaging item.

[0011] The packaging item comprises at least one cylindrical container made of a multilayer oxygen- and moisture-barrier laminate comprising a paperboard and an organic and / or inorganic barrier layer. The paperboard has a basis weight between 120 and 600 g / m2 and a cellulose content higher than 90%, preferably higher than 95%, more preferably higher than 99%. The cylindrical container includes at least one perimeter wall and a container bottom closure system that define at least one compartment for the contents of the package.

[0012] In a preferred embodiment of the invention, the outer wall of the container can be manufactured from a multilayer cellulose-based material that has barrier properties against the transfer of oxygen and / or moisture and that comprises the me Petition 870250094163, dated 10 / 15 / 2025, page 12 / 89 4 / 59 in the following layers, from its inner side (oriented towards the inside of the container) to its outer side: - at least one organic sealing layer made of an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2, then - at least one inorganic barrier layer providing moisture barrier properties selected from the list of: metals, metalloids, or a combination thereof, said inorganic layer having a thickness between 1 and 100 nm, and - at least one organic barrier layer providing oxygen barrier properties comprising a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH) or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - a layer of paper with a basis weight in the range of 30 to 120 g / m2, - an adhesive, preferably a water-based or solvent-free adhesive, with a base compound preferably selected from the list of: poly(vinyl acetate) (PVAc), polyurethane (PU), acrylic, polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), vinyl alcohol-butenediol copolymer (BVOH), a starch-based adhesive, a modified cellulose-based adhesive or a combination thereof, wherein said adhesive layer has a thickness preferably in the range of 1 to 10 µm, Petition 870250094163, dated 10 / 15 / 2025, page 13 / 89 5 / 59 - cardboard or cardstock with a basis weight in the range of 120 g / m2 to 600 g / m2.

[0013] The container additionally includes at least one dispensing opening configured to allow the packaged contents to be dispensed from the container through the dispensing opening. The dispensing opening may be of the type that requires full opening of the packaging (typically removing at least one element from the rest of the packaging). Alternatively or additionally, the packaging may include a second type of dispensing opening that does not require full opening of the packaging, especially a dispensing opening that requires only the displacement of an element relative to the rest of the packaging, for example, twisting, turning or flipping a portion of the packaging relative to the rest of the packaging in order to open / close the packaging.

[0014] The multilayer oxygen and moisture barrier laminate comprising paperboard and an organic and / or inorganic barrier layer increases the resistance of the container and therefore of the packaging item against the transfer of oxygen and moisture, for example, compared to packaging items made of paper that are known from the prior art. This results in greater protection, preservation and / or longer shelf life of the contents inside the container.

[0015] As understood in the context of the present invention, a cylinder preferably has a circular cross-section (or baseline). However, other, for example, polygonal or elliptical baselines (i.e., cross-sections) may also be considered as cylindrical within the framework of the present invention. Preferably, the cylinder is a right cylinder. However, oblique cylinders may also be considered.

[0016] As understood in the context of the present invention, a Petition 870250094163, dated 10 / 15 / 2025, page 14 / 89 6 / 59 Paperboard is a flat cellulosic structure of one or more layers of paper having a basis weight between 120 g / m2 and 600 g / m2. Below 120 g / m2, a flat cellulosic structure will be considered under the term paper in the context of the present invention.

[0017] The packaging item further comprises at least one top sleeve element with at least one perimeter wall of the sleeve element, wherein the sleeve element is configured to slide over at least one top end portion of the perimeter wall of the cylindrical container, such that the perimeter wall of the sleeve element at least partially encloses the perimeter wall of the container and the sleeve element at least partially covers the dispensing opening. Said sleeve element is made of a multilayer oxygen- and moisture barrier laminate comprising at least one paperboard and an organic and / or inorganic barrier layer. The paperboard has a basis weight between 120 and 600 g / m2 and a cellulose content higher than 90%, preferably higher than 95%, more preferably higher than 99%.As stated previously, the multilayer oxygen and moisture barrier laminate comprising paperboard and an organic and / or inorganic barrier layer increases the container's resistance against oxygen and moisture transfer.

[0018] Setting up the sleeve element to slide over at least a portion of the top end of the container perimeter wall so that the perimeter wall of the sleeve element at least partially encloses the container perimeter wall and the sleeve element at least partially covers the dispensing opening provides greater protection of the contents within the container. In particular, this provides at least double-wall protection of the packaged contents through the container perimeter wall and the wall Petition 870250094163, dated 10 / 15 / 2025, page 15 / 89 7 / 59 peripheral glove element. Furthermore, this allows the glove element to be used to reseal the dispensing opening of the container after the initial opening, in a way that maintains the oxygen and moisture barrier properties.

[0019] Alternatively or additionally, such a glove element may be used for advertising and / or informational and / or aesthetic purposes, for example, by providing printing at least partially on the glove element, while the container may be configured primarily to protect and / or preserve the contents of the packaging item, in particular in a hygienic and / or food-safe manner. For example, the container may be free of printing, adhesives, etc. This minimizes the risk of diffusion of color printing or adhesives, for example, to the packaged contents (for example, even if the barrier layer is very thin and / or the packaged contents are stored for long periods of time). This may also allow the container and the glove element to be manufactured from different materials and / or different material compositions and / or different thicknesses.The perimeter wall of a sleeve element can completely enclose the perimeter wall of a container in a circumferential direction along a certain portion of the container's length.

[0020] The packaging item further comprises at least one bottom base element with at least one perimeter wall of the base element, the base element at least partially enclosing and optionally, but preferably, immovably fixed to a bottom end portion of the perimeter wall of the container. Said base element is made of paperboard having a basis weight between 120 and 600 g / m2 and a cellulose content higher than 90%, preferably higher than 95%, more preferably higher than 99%. Petition 870250094163, dated 10 / 15 / 2025, page 16 / 89 8 / 59

[0021] Preferably, but not necessarily, the base element is made of a multi-layered oxygen- and moisture-barrier laminate comprising said paperboard. The base element provides a support surface for the packaging item to rest on, for example, on a tabletop. This allows the base element to be configured primarily to provide a reliable and robust interface between the packaging item and an external surface, for example, a tabletop. Preferably, the base element does not contain / house any of the packaged contents. Preferably, the base element is not in direct contact with the packaged contents of the packaging item. Thus, this eliminates or at least reduces deformation of the base element caused by the packaged contents, which increases the stability of the packaging item when resting on a surface by means of the base element.Ideally, the container's bottom closure system remains covered / sealed on the container throughout the use of the packaging item, that is, at least until the packaged contents of the packaging item have been completely dispensed from the packaging item.

[0022] Furthermore, configuring the respective paperboard to have a basis weight between 120 and 600 g / m2 increases the robustness and stability of the packaging item, especially in the vertical or axial direction (top load). However, the paperboard material is also particularly advantageous due to the fact that it is sufficiently flexible, especially in the transverse direction, to be collected after use, so that it can occupy less space when discarded for recycling. In particular, the container and / or the sleeve element and / or the base element is / are preferably dimensionally stable / rigid.

[0023] Configure the paperboard to have a cellulose content Petition 870250094163, dated 10 / 15 / 2025, page 17 / 89 9 / 59 significantly high, for example, higher than 90%, preferably higher than 95%, more preferably higher than 99%, reduces the density and / or production costs and / or increases the biodegradability and / or recyclability of the packaging item, for example, compared to materials that have a lower cellulose content.

[0024] In an important aspect of the invention, the sleeve element is dimensioned and configured so that, when the packaging is in its fully closed configuration, said sleeve element overlaps the container element by at least 25 mm, preferably at least 50 mm, more preferably at least 80 mm depending on the dimensions of the container, as disclosed herein.

[0025] In another important aspect of the invention, the sleeve and container elements have a functional clearance (i.e., the difference between the inner diameter of the sleeve element and the outer diameter of the container element of the packaging) that is sufficient to ensure proper fixation of the two in the closed configuration of the packaging, and so that no complex capping is required, such as threads or cutting mechanisms. By selecting a functional clearance that is preferably between 50 and 500 μm, preferably between 100 and 300 μm, the possibility of easily sliding the top sleeve element over the core container element is ensured, while the adhesion between the two elements is sufficiently high to prevent one element from sliding relative to the other without applying an external force.

[0026] The combination of functional clearance and overlap between the sleeve and container elements ensures the tightness of the packaging in its closed configuration, which allows for the so-called shelf life after opening. Shelf life after opening means that, when the packaging is opened for the first time, the contents will remain airtight. Petition 870250094163, dated 10 / 15 / 2025, page 18 / 89 10 / 59 times, it can be closed again after the first use, ensuring that moisture and oxygen influx into the contents are very limited.

[0027] The packaging item, more specifically the container, is configured to house and / or preserve, at least for a certain period of time, food material in the compartment, that is, any material used as food, for example, edible / drinkable material, or used to make / produce food. The packaged material, for example, food material, can be liquid and / or solid. Preferably, the packaged material is solid and in fluid form, in particular in powder form. The powder can have various granularity values, from small to coarse diameter particles, or be a mixture of large and small diameter powder particles. It can also take the form of bran or solid particle items of various shapes and sizes, which are individually pre-packaged food items or not.The type of food product can be wide-ranging, such as, for example, coffee particles or solids, potato chips, chocolate solids, pet food bran, compacted edible items, such as, for example, compacted coffee shots, etc.

[0028] The above-identified components of the packaging item, for example, the container, the sleeve element and the base element, may be supplied in a range of different dimensions. Preferably, the container may have a width / diameter in the range of 20 mm to 200 mm. Preferably, the container may have a length in the range of 50 mm to 500 mm, preferably from 75 mm to 250 mm.

[0029] Preferably, the diameters of the elements are such that they allow comfortable handling by a user's hand. The diameter is advantageously between 20 and 200 mm, preferably Petition 870250094163, dated 10 / 15 / 2025, page 19 / 89 11 / 59 reference, between 40 and 100 mm.

[0030] The dispensing opening may be located at one end of the container, for example, at the top end of the container. Alternatively, or additionally, the dispensing opening may be located at least partially on the perimeter wall of the container.

[0031] The container bottom closure system may be a membrane and / or a metal sheet, for example, a metal, for example, aluminum, or a metallized material, for example, metallized paper or a metallized plastic, such as a metallized polyolefin, preferably a metallized polypropylene or a metallized polyethylene terephthalate (PET), whose thickness is preferably between 5 and 30 microns, more preferably between 10 and 15 microns. Alternatively or additionally, the container bottom closure system may be made of non-metallized plastic, for example, a polymer such as polyethylene terephthalate (PET) or a layer of a polyolefin such as polyethylene (PE), whose thickness is between 20 and 60 microns.

[0032] The percentage(s) of content of the material(s) mentioned above, for example, the cellulose content, is / are defined as % by weight in relation to a total weight of the respective material.

[0033] Preferably, at least one section of the base element projects from the container beyond the container bottom closure system. Thus, when the container is placed on a surface (e.g., a tabletop), with the base element resting on the surface, the base element can space the container bottom closure system from the surface. This can prevent mechanical damage to the container bottom closure system. In addition, this can allow the packaging item to be well supported on the surface in a substantially independent manner. Petition 870250094163, dated 10 / 15 / 2025, page 20 / 89 12 / 59 tooth of a state of the container bottom closure system, for example, even if the container bottom closure system is deformed, for example, if the container bottom closure system bends due to the weight and / or volume of the contents packed inside the container.

[0034] Preferably, the packaging item additionally includes at least one protrusion. The sleeve element, preferably a bottom end of the sleeve element, can be configured to be at least partially contiguous with the protrusion when the sleeve element is slid over the container. Preferably, the edge is defined at an interface between the base element and the container. In other words, the protrusion can be used as a stop for the sleeve element that can provide an easier, more intuitive and / or more reliable closure system for the packaging item by a user. Furthermore, the protrusion can provide haptic and / or optical feedback to the user to ensure proper closure of the container by means of the sleeve element.The overhang can be provided by sizing the base element wider than the container in at least one direction in which the overhang extends, for example, by configuring the base element to have a larger diameter than the container.

[0035] Preferably, the protrusion can be defined at least partially by an upper end of the base element, preferably at least partially by an upper end of the perimeter wall of the base element. In other words, a bottom end of the sleeve element can at least partially rest against and / or be contiguous with the top end of the perimeter wall of the base element when the sleeve element is slid over the container. Preferably, a shape and / or a size, for example, a circumference, of the end of the Petition 870250094163, dated 10 / 15 / 2025, p. 21 / 89 13 / 59 po of the base element may substantially coincide with the shape and / or size of the bottom end of the sleeve element.

[0036] This contiguity feature of the base element with the sleeve element, when the packaging item is in its fully closed configuration, ensures that the mechanical resistance of the packaging item against a top load (i.e., in the vertical or axial direction) is guaranteed, due to the fact that the forces exerted in the vertical direction are maintained by three points of contact: - A first point of contact at the interface between the upper edge of the cylindrical container and the inner surface of the upper wall of the sleeve element, - A second point of contact at the interface between the lower edge of the cylindrical container (and the cylindrical container bottom closure system) and the inner surface of the lower wall of the base element, and - A third point of contact between the lower edge of the sleeve element and the upper edge of the base element.

[0037] In this configuration, the three constituent elements of the packaging item, namely the container, the sleeve element and the base element, fully support the stacking forces that are applied in the axial (vertical) direction on the packaging item. The compressive forces that are applied to each element of the packaging item individually are therefore reduced, and the integrity of each of the container, the sleeve element and the base element is preserved. The amount of material used to make each of these elements can be reduced, but the mechanical strength of the entire packaging item is maintained.

[0038] The stackability of the entire packaging item is therefore guaranteed, which ensures the integrity of each package. Petition 870250094163, dated 10 / 15 / 2025, page 22 / 89 14 / 59 individual not be affected when many of these packages are stacked on top of each other for transport or storage.

[0039] Preferably, the sleeve element and / or the base element is cylindrical. More preferably, the sleeve element and / or the base element is shaped as a cylinder that has a circular baseline (i.e., cross-section). The inner and / or outer diameter of the cylinder forming the sleeve element and the cylinder forming the base element may be the same. Cylindrical means – within the framework of this descriptive report – that the container, the sleeve element and / or the base element may be shaped as a cylinder that also has an elliptical or polygonal cross-section.

[0040] Preferably, the sleeve element and / or the container is / are configured so that the sleeve element can be removed and slid over the container multiple times. This may allow the container to be opened and reclosed multiple times by the sleeve element.

[0041] Preferably, the packaging item additionally includes at least one container top closure system configured to close, preferably in a sealed manner, the top edge dispensing opening of the cylindrical container, in order to prevent the packaged contents from being dispensed through the dispensing opening. Preferably, the container top closure system is at least partially removable, preferably peelable, from the dispensing opening.

[0042] In one embodiment, the upper edge of the perimeter wall of the container may comprise an inwardly inclined portion directed toward the interior of the container. An annular ring (or collar or washer) is sealed under the inwardly inclined portion, inside the container. The annular ring may be a flat ring comprising an outer portion inclined at its periphery. The outer diameter and width Petition 870250094163, dated 10 / 15 / 2025, page 23 / 89 15 / 59 The shape of the annular ring is such that at least the outer inclined portion of the annular ring radially overlaps the inward inclined portion of the container to allow for a proper seal between the two. Preferably, the radial overlap between the inclined portion of the annular ring and the inclined portion of the upper edge of the container has a width between 1 and 10 mm, more preferably between 3 and 7 mm. The inner flat portion of the annular ring projects inward from the inclined portion of the container, thus leaving an inner sealing surface of the annular ring that is sufficient to allow for the proper sealing of a container top closure system thereon. Preferably, the inner sealing surface of the annular ring has a width between 1 and 5 mm, more preferably between 2 and 3 mm. The inclined portion of the annular ring has an effect of stiffening the ring in both the axial and radial directions.Similarly, the inward-sloping portion of the upper edge of the container also stiffens that portion of the container both radially and axially. The axial direction is, by convention, the direction oriented along the vertical axis of symmetry of the packaging item, while a radial direction is a direction oriented in a plane, generally perpendicular to the axial direction. By sealing the two sloping portions described above, the sealing portion between the annular ring and the container wall is endowed with good resistance against mechanical deformation, in the axial direction and also, more importantly, in the radial direction.

[0043] The annular ring can be manufactured from laminated paper, cardboard, metal, a plastic, such as a biodegradable or recyclable polymer, or a combination thereof. In a preferred embodiment, the annular ring is manufactured from a multilayered cardboard that has barrier properties against oxygen and / or moisture transfer. More precisely, in such Petition 870250094163, dated 10 / 15 / 2025, page 24 / 89 16 / 59 preferred embodiment, the annular ring is a flat ring comprising at least the following layers, from its upper side to its lower side (oriented towards the interior of the container): - at least one organic sealing layer made of an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2, then - at least one inorganic barrier layer providing moisture barrier properties selected from the list of: metals, metalloids, or a combination thereof, said inorganic layer having a thickness between 1 and 100 nm, and - at least one organic barrier layer providing oxygen barrier properties comprising a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH) or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - a layer of paper with a basis weight in the range of 30 to 120 g / m2, - an adhesive, preferably a water-based or solvent-free adhesive, with a base compound preferably selected from the list of: poly(vinyl acetate) (PVAc), polyurethane (PU), acrylic, polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), vinyl alcohol-butenediol copolymer (BVOH), a starch-based adhesive, a modified cellulose-based adhesive, or a combination thereof, wherein said adhesive layer has a thickness preferably in the range of 1 to 10 Petition 870250094163, dated 10 / 15 / 2025, page 25 / 89 17:59 pm - cardboard or cardstock with a basis weight in the range of 120 g / m2 to 600 g / m2.

[0044] The oxygen and / or moisture barrier properties obtained by the annular ring are preferably similar to the barrier properties of the material used to manufacture the outer wall of the container. The sealing overlap between the container and the ring and the orientation of the layers in each of these two elements ensure adequate continuity of the barrier properties in the sealing zone. For this purpose, it is also preferable that the cellulosic layers (e.g., paper, cardboard, paperboard) in the outer wall of the container face outwards, while the organic and inorganic barrier layers and the sealing layer face inwards, and conversely, the barrier layers and the sealing layer of the annular ring are oriented outwards, and its cellulosic layers face inwards (in contact with the contents of the container).The annular ring ensures adequate continuity of oxygen and / or moisture barrier properties between the container and the container top closure system.

[0045] The container top closure system is preferably sealed on the upper surface of the annular ring that projects inward from the inclined portion of the container, along the entire periphery of said ring. As described above, the role of the annular ring is to mechanically reinforce the rigidity of the container in the region of its opening, so that any radial force applied to the container walls in the upper region of the container does not result in deformation of the container.

[0046] Due to its sloping profile, the upper portion of the container's perimeter wall surrounding the dispensing opening facilitates Petition 870250094163, dated 10 / 15 / 2025, page 26 / 89 18 / 59 also inserts the container into the sleeve element, which facilitates the ability to reseal the packaging item. This is particularly important due to the fact that the packaging item is designed to be opened and resealed multiple times.

[0047] The container top closure system may be a membrane and / or a metal sheet, for example, a metal, for example, aluminum, or a metallized material, for example, metallized paper or a metallized plastic, such as a metallized polyolefin, preferably a metallized polypropylene. Alternatively or additionally, the container top closure system may be made of plastic, for example, a polymer such as polyethylene terephthalate (PET).

[0048] In one embodiment, the top closure system is a multilayer membrane comprising a layer of aluminum foil, preferably between 20 and 60 microns thick, and a sealable plastic layer, for example, a polyolefin, such as a high-density polyethylene (HDPE) layer, bonded to the aluminum foil layer with an adhesive. The thickness of the sealable plastic layer is preferably between 10 and 40 microns, more preferably between 20 and 30 microns. The advantage of such a peelable aluminum foil membrane is that it achieves extremely high barrier properties against oxygen and moisture transfer.The oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) values ​​measured for such types of aluminum membranes are so low that they are almost immeasurable and are therefore considered a benchmark in terms of barrier efficiency in the industry.

[0049] However, in an alternative arrangement, in order to guarantee a high cellulosic content for the recyclability of the packaging item Petition 870250094163, dated 10 / 15 / 2025, page 27 / 89 19 / 59 gem, the top closure system can be made of a paper-based membrane that can be heat-sealed or ultrasonically bonded and is recyclable in a paper flow process. For this purpose, the membrane can comprise at least 90% cellulose fibers. In such a case, it can comprise at least one very thin organic and / or inorganic layer attached to a paper layer in order to provide oxygen and / or moisture barrier properties that are similar to the barrier properties of the container's perimeter wall. In a preferred embodiment of the invention, the membrane comprises the following layers, in order from its outer side to its inner side (the inner side being the side in contact with the contents of the container): - a layer of paper with a basis weight in the range of 30 to 120 g / m2, - at least one organic barrier layer of a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH) or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - at least one inorganic barrier layer selected from the list of: metals, metalloids, or a combination thereof, wherein said inorganic layer has a thickness between 1 and 100 nm, and - at least one organic sealing layer made of an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2.

[0050] In general, inorganic layers provide a barrier Petition 870250094163, dated 10 / 15 / 2025, page 28 / 89 20 / 59 against moisture transfer (i.e., water vapor), while the organic layers provide a barrier against oxygen transfer.

[0051] The peelable membrane is preferably attached to the outer wall of the container by a heat-bonding process, but alternatives such as an ultrasonic sealing process can also be used.

[0052] In other words, the container top closure system can provide a moisture and oxygen barrier that is removable after the initial opening of the packaging item by the consumer (e.g., after removing the glove element). Subsequently, the container opening can be closed again by sliding (or sliding again) the glove element over the container. After the removal of the container top closure system during the first use of the packaging item, it is the glove element that is able to provide oxygen and / or moisture barrier properties to the packaging item.

[0053] The container further comprises a container bottom closure system (or container bottom wall) which is preferably made of a material that achieves oxygen and / or moisture barrier properties similar to those of the material used to make the container walls.

[0054] In one embodiment, the container bottom closure system may be a multilayer metal sheet comprising a first layer of metallized polyethylene terephthalate (PET) with a thickness of 12 microns that is bonded to a second layer of polyethylene (PE) with a thickness of 40 microns.

Alternatively or additionally, the second opening 140 can function as a pouring opening that allows the contents to be dispensed through it, preferably after sliding the sleeve element 114 upwards and / or in the opposite direction to the container 102.

[0097] In one embodiment, which is only optional, an element 142 can be moved back to the second opening 140, preferably through the interaction between the sleeve element 114 and the container 102 while the sleeve element 114 is slid over or additionally over the container 102. This can allow the second opening 140 to be at least partially resealed by means of the movable element 142.

[0098] Preferably, the cylindrical container 102 is free of printing and / or labels. The sleeve element 114 may include one or more prints and / or labels 144, as shown in Figures 1 and 2.

[0099] Packaging item 100 additionally includes a protrusion 146. Protrusion 146 is defined by an end 147 of the base element 122, in particular a distal edge 148 of the peripheral wall of the base element 124. The sleeve element 114 is configured to be at least partially contiguous with the protrusion 146 when the sleeve element 114 is slid over the container 102, as shown in Figure 2.

[00100] More precisely, this contiguity feature of the base element with the sleeve element, when the packaging item is in its fully closed configuration, ensures that the mechanical resistance of the packaging item against a load of Petition 870250094163, dated 10 / 15 / 2025, page 49 / 89 41 / 59 top (that is, in the vertical direction) is guaranteed, due to the fact that the forces exerted in the vertical direction are maintained by three points of contact: - A first point of contact at the interface between the upper edge of the cylindrical container and the inner surface of the upper wall of the sleeve element, - A second point of contact at the interface between the lower edge of the cylindrical container (and the cylindrical container bottom closure system) and the inner surface of the base element, and - A third point of contact between the lower edge of the sleeve element and the upper edge of the base element.

[00101] The stackability of the entire packaging item is therefore guaranteed, which ensures that the integrity of each individual package is not affected when many of these packages are stacked on top of each other for transport or storage.

[00102] Figure 3 shows an enlarged view of the container top closure system 132 of packaging item 100 of Figures 1 and 2. As shown schematically in Figure 3, the container top closure system 132 is preferably sealed, preferably by adhesive, to an annular ring (or collar or washer) 180 of the container 102. The container top closure system 132 may be configured to be detachable from the annular ring 180, in particular from the annular ring 180, and / or the container top closure system 132 may be perforable to at least partially open the dispensing opening 110. The annular ring 180 may be made of paperboard. Alternatively, the annular ring 180 may be formed as a section of the perimeter wall of the container 104.As described above, the main role of the annular ring 180 is to mechanically reinforce the rigidity of the container 102 in the region of its dispensing opening 110, so that any... Petition 870250094163, dated 10 / 15 / 2025, pp. 50 / 89 42 / 59 radial force applied to the container walls in the upper region of the container does not result in its deformation. Furthermore, the annular ring 180 is preferably manufactured from a material that has barrier properties against the transfer of oxygen and moisture, so that said annular ring 180 allows a continuity of the oxygen and / or moisture barrier between the container 102 and the container top closure system 132.

[00103] Figures 4 to 6 schematically show different embodiments for configuring the container bottom closure system 106. As shown schematically in Figure 4, the container bottom closure system 106 can be fixed, preferably by sealing, preferably by adhesive, to an inner side 154 of the container perimeter wall 104.

[00104] As shown schematically in Figure 5, the bottom closure system 106 can be attached to an enlarged section 158 of the container 102 that extends outwards, in particular radially outwards, in the opposite direction to the compartment 108. The enlarged section 158 extends axially away from the dispensing opening 110.

[00105] As shown schematically in Figure 6, the bottom closure system 106 can be attached to a section 160 of the container 102 that extends outwards, in particular radially outwards, in the opposite direction to the compartment 108 and axially towards the dispensing opening 110.

[00106] As shown in Figures 7A and 7B, the packaging may comprise a dispensing opening 170 on the side of the glove element 114. By lifting the glove element 114 (without detaching it from the rest of the packaging), a passage is created between the inner compartment of the packaging and the dispensing opening 170, so as to create a passage for the product. The diameter (comprising Petition 870250094163, dated 10 / 15 / 2025, page 51 / 89 43 / 59 (5 mm and 30 mm) of the dosing opening is sufficient to allow some product to flow out in a measured quantity and flow, which allows convenient dosing of the product as illustrated in Figure 7B. After dosing, the sleeve element 114 is pushed back into the rest of the packaging to close the latter.

[00107] Figures 8A and 8B illustrate two alternative configurations for constructing sleeve element 114 and / or base element 122.

[00108] As described above, base element 122 comprises a perimeter wall of base element 124, a bottom wall of base element 160 that at least partially covers the surface of the bottom opening in the base element. Sleeve element 114 comprises a perimeter wall of sleeve element 116 and a top wall of sleeve element 150 that at least partially closes the top end of said sleeve element.

[00109] In one embodiment, the outer wall of the base element can be manufactured from a cellulose-based material (e.g., paper or paperboard) to which at least one layer of an oxygen and / or moisture barrier material is attached. The oxygen and / or moisture barrier material may comprise at least one organic and / or inorganic layer. The at least one oxygen and / or moisture barrier layer may be bonded to the cellulose base layer by extrusion, lamination, or an aqueous dispersion process. In the case of an inorganic layer, it may be deposited by a vacuum deposition process as an ultrathin layer of nanometer thickness.

[00110] In an embodiment illustrated in Figure 8A, the perimeter walls of the base element and the sleeve element are manufactured from a multilayer packaging material structure comprising, from the outside in, the following layers: Petition 870250094163, dated 10 / 15 / 2025, page 52 / 89 44 / 59 - a layer of cardboard with a basis weight between 120 g / m2 and 600 g / m2, - an optional adhesive layer with a basis weight between 0.5 and 10 g / m2, - a layer of paper with a basis weight between 30 and less than 120 g / m2, - at least one organic barrier layer of a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - at least one inorganic barrier layer selected from the list of: metals, metalloids, or a combination thereof, wherein said inorganic layer has a thickness between 1 and 100 nm, and - at least one layer of organic heat-bonding made of an acrylic or methacrylic acid polymer or polyolefin grafted with at least one type of ionomer, preferably a sodium ionomer, preferably an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2.

[00111] The inorganic layer may comprise metals or metalloids selected from the list of: aluminum, aluminum oxide (AlOx) or silicon oxide (SiOx), wherein said metals and / or metalloids are deposited by vacuum deposition or transfer metallization.

[00112] In this embodiment, schematically illustrated in Figure 8A, the group of barrier layers 190, which especially comprises a metallized layer, faces the interior of the container. Petition 870250094163, dated 10 / 15 / 2025, page 53 / 89 45 / 59 (not visible from the outside when the packaging item is closed), while the 200 cellulosic layer (cardboard, paper) is oriented towards the outside of the container.

[00113] In an alternative embodiment of the invention illustrated in Figure 8B, the order of the layers of the peripheral wall is reversed compared to the first embodiment previously described illustrated in reference to Figure 8A. In this alternative embodiment, the barrier layer group 190, which especially comprises a metallized layer, faces outwards, while the cellulosic (cardboard, paper) layer 200 is oriented inwards. This configuration gives the packaging item 100 a metallic appearance on the outside, especially when closed. This alternative embodiment provides an outer surface of the packaging item that has a very smooth surface, even at the microscopic level, due to the metallization layer and the outermost organic heat-bonding layer. Such a smooth surface provides an advantage and is therefore preferable when the outer surface of the base element 122 and / or the outer surface of the sleeve element 114 is printed.This allows the use of a flexographic printing technique, which is less expensive than a digital printing technique that is usually required to print on a rough cardboard or paper surface.

[00114] In both embodiments described above with reference to Figures 8A and 8B, the bottom wall of base element 160 and the top wall of sleeve element 150 may be made of the same material as the perimeter walls of the base and sleeve elements to which they are attached. The top wall of sleeve element 150 comprises a flat disc having an outer circumferential portion 151 that is slightly inclined downwards, as shown in Figures 8A and 8B. The upper portion 152 of the perimeter wall of Petition 870250094163, dated 10 / 15 / 2025, page 54 / 89 46 / 59 element of sleeve 114 is also inclined towards the inner volume of the sleeve, so that the inclined portions 151, 152 of both elements overlap and can be sealed together, as illustrated in Figures 8A and 8B.

[00115] In the embodiments shown in Figures 8A and 8B, an additional membrane 210 can be attached to the outer surface of the inclined portion 152 of the sleeve element perimeter wall and to the outer surface of the top wall 150. The additional membrane 210 comprises the following layers, in order from its outer side to its inner side (the inner side being the side in contact with the outer surfaces of the sleeve element perimeter wall 116 and the top wall 150): - a layer of paper with a basis weight in the range of 30 to 120 g / m2, - at least one organic barrier layer of a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH) or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - at least one inorganic barrier layer selected from the list of: metals, metalloids, or a combination thereof, wherein said inorganic layer has a thickness between 1 and 100 nm, and - at least one organic sealing layer made of an acrylic or methacrylic acid ionomer, preferably an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2. Petition 870250094163, dated 10 / 15 / 2025, page 55 / 89 47 / 59

[00116] The additional membrane serves to protect the sealing zone 220 between the peripheral wall of the glove 116 and the top closure system 150, against scratches or accidental detachment. Furthermore, in the embodiment shown in Figure 8B, when the peripheral wall of the glove 116 is made of a material in which the cellulosic layer is rotated to the inside of the packaging item and the oxygen and / or barrier layer is rotated to the outside, it has been found that the oxygen and / or moisture barrier properties in the sealing zone 220 may be diminished due to the fact that the seal occurs between the innermost cellulose-based layer 200 of the peripheral wall of the glove and the outermost cellulosic layer of the glove top closure system 150.In this case, it was found that a membrane 210 comprising at least one layer of an oxygen and / or moisture barrier material, especially as described above, can provide additional oxygen and / or barrier protection to protect the contents of the packaging item. This additional protection is due to the fact that the organic and inorganic barrier layers of membrane 210 are placed adjacent to the organic and / or inorganic barrier layers 190 of the peripheral wall 116 of the sleeve 114.

[00117] The same construction applies to base element 122 and to the base element (or wall) closure system 160 attached to it.

[00118] Figures 9A and 9B show an embodiment of a packaging item 100 according to the invention. Figure 9A is a split view of the various constituent elements described above, while Figure 9B represents a packaging item 100 in its fully enclosed configuration.

[00119] A container 102 is manufactured from a cylindrical tube forming a perimeter wall of container 104. The bottom portion Petition 870250094163, dated 10 / 15 / 2025, pp. 56 / 89 48 / 59 of the peripheral wall of container 104 is closed with a bottom wall of container 106, and the upper portion of the peripheral wall of container 104 is closed by a peelable membrane 132 through an annular ring 180 that interfaces between the membrane 132 and the peripheral wall of container 104. The internal volume of container 102 defines a compartment 108 to contain a product.

[00120] A top sleeve element 114 is manufactured from a cylindrical tube forming a sleeve perimeter wall 116, which has an inner diameter such that it is able to slide by friction on the container perimeter wall 102 in order to open and close the packaging item 100. The top of the sleeve perimeter wall 104 is closed with a sleeve top wall 150 covered on its outer side by a membrane 210 that overlaps the sealing zone between said sleeve top wall 150 and said sleeve perimeter wall 102.

[00121] A base element 122 is manufactured from a cylindrical tube that forms a perimeter wall of a base element 124, which has an internal diameter such that it can be placed by friction on the perimeter wall of a container 102. The bottom of the perimeter wall of the base element 124 is closed with a bottom wall of a base element (or closing system) 160 covered on its outer side by a membrane 210 that overlaps the sealing zone between said bottom wall of the base element 160 and said perimeter wall of the base element 124. Preferably, the base element 122 is permanently fixed to the container 102.

[00122] The perimeter walls 104, 116, 124 of the container, sleeve element and base element, as well as the bottom wall of the base element 160 and the top wall of the sleeve element 150 can be manufactured from a multi-layered packaging material structure comprising, from the outside in, the following layers: Petition 870250094163, dated 10 / 15 / 2025, p. 57 / 89 49 / 59 - a layer of cardboard with a weight between 120 g / m2 and 600 g / m2, - an optional adhesive layer with a basis weight between 0.5 and 10 g / m2, - a layer of paper with a basis weight between 30 and less than 120 g / m2, - at least one organic barrier layer of a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - at least one inorganic barrier layer selected from the list of: metals, metalloids, or a combination thereof, wherein said inorganic layer has a thickness between 1 and 100 nm, and - at least one layer of organic heat-bonding made of a grafted ionomer of acrylic or methacrylic polyolefin polymer, preferably a sodium ionomer, preferably an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2.

[00123] The inorganic layer may comprise metals or metalloids selected from the list of: aluminum, aluminum oxide (AlOx - aluminum oxide) or silicon oxide (SiOx - silicon oxide), wherein said metals and / or metalloids are deposited by vacuum deposition or transfer metallization.

[00124] Membranes 210 can be manufactured from a multilayer material comprising the following layers, in Petition 870250094163, dated 10 / 15 / 2025, pp. 58 / 89 50 / 59 order from its outer side to its inner side (the inner side being directed towards the inside of the packaging item): - a layer of paper with a basis weight in the range of 30 to 120 g / m2, - at least one organic barrier layer of a polymer selected from the list of: polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH) or a combination thereof, in an amount of 0.5 to 20 g / m2, preferably in an amount of 1 to 10 g / m2, more preferably in an amount of 2 to 8 g / m2, - at least one inorganic barrier layer selected from the list of: metals, metalloids, or a combination thereof, wherein said inorganic layer has a thickness between 1 and 100 nm, and - at least one organic sealing layer made of an ethylene acrylic or methacrylic acid ionomer, wherein said heat-bonding layer is applied in an amount between 2 and 20 g / m2, preferably in an amount between 4 and 9 g / m2.

[00125] In the embodiment shown in Figures 9A and 9B, the material for forming the peripheral walls of the sleeve element 114 and the base element 122 can therefore be layered with a cellulosic layer 200 facing the outside of the packaging item 100 and the organic and / or inorganic barrier layers 190 against oxygen and / or moisture transfer are oriented to face the inside of the packaging item 100. As a result, in the embodiment illustrated in Figures 9A and 9B, the external appearance of the packaging item 100 in its closed state is that of a cellulosic package (paper or paperboard).

[00126] However, the material of the peripheral walls of the element Petition 870250094163, dated 10 / 15 / 2025, pp. 59 / 89 51 / 59 of the glove and the base element can be reversed, so that the external appearance of the packaging can be that of a metallized package.

[00127] The height of the sleeve element and the base element may be the same, but they may also have a different height. However, in a highly preferred embodiment of the invention, the height of the sleeve and the base element is chosen so that, in the closed configuration of the packaging item, the lower edge of the sleeve element 114 contacts a protrusion 146 of the base element 122, as illustrated in Figure 9B, and the inner surface of the top wall of the sleeve element 150 contacts the upper surface of the container and the inner surface of the bottom wall of the base element 160 contacts the lower surface of the container 102.

[00128] Several aspects and embodiments of the invention have been described for illustrative purposes. The invention, however, should not be unduly limited by any of the details of the disclosure above, since it will be recognized by those skilled in the art that alterations and modifications that do not contradict the principle of the invention can be made and still be covered by the invention. In particular, the invention should not be interpreted as limited to the embodiments described above with reference to the drawings. Instead, the scope of protection of the invention is determined solely by the appended claims and their equivalents.

[00129] In general, the packaging according to the present invention provides a number of advantages and benefits to a user as follows.

[00130] It provides a unique structural design, using a uniquely shaped and sized cardboard packaging; the construction is made of cardboard that is recyclable in a pro Petition 870250094163, dated 10 / 15 / 2025, pp. 60 / 89 52 / 59 paper flow access.

[00131] It comprises an innovative closure system: a tube-type packaging with an innovative lift-and-push mechanism for a closure system that the user can easily open, close, and reseal (easy to seal and reseal, while being safe and protective). In particular, the only fixation for the top sleeve element in the core container is made by sliding one over the other. The functional clearance between the two is sufficient to ensure proper fixation, and so that no complex capping is required, such as threads or a cutting mechanism. By selecting a functional clearance that is preferably between 50 and 500 μm, preferably between 100 and 300 μm, the possibility of easily sliding the top sleeve element over the core container element is ensured, while the adhesion between the two elements is sufficiently high to prevent one element from sliding relative to the other without applying an external force.Functional clearance refers to the difference between the inner diameter of the sleeve element and the outer diameter of the packaging container element.

[00132] The innovative packaging according to the present invention provides so-called shelf-life capabilities after opening, meaning that after the packaging is first opened for use, its closed configuration allows it to maintain a high level of barrier, which prolongs the shelf life of the contents. This shelf life after opening is possible because moisture and oxygen transfer are minimal when the top sleeve element completely closes the container element. In such a closed position, the packaging still has oxygen transmission rate (OTR) values ​​below 1, preferably below 0.5 cm3 / m2 / day measured at 23 °C and 50% relative humidity (RH). Petition 870250094163, dated 10 / 15 / 2025, pp. 61 / 89 53 / 59 Water vapor transmission rate (WVTR) values ​​below 1, preferably below 0.5 g / m² / day measured at 23 °C and 85% RH. This is because the functional clearance (i.e., the space) between the inner surface of the sleeve element and the outer surface of the container element is sufficiently small and, simultaneously, the overlap between the sleeve and the container elements is sufficiently high, to ensure that – while allowing movement between the two by applying a sliding force – the transfer of moisture and gases is largely avoided.

[00133] The packaging according to the invention may advantageously comprise holes / perforations in the paperboard structure that allow for precise and easy-to-use dosing of its contents, such as a dosing dispenser or dosing mechanism, which allows the user to dispense a specific quantity of product from the packaging, typically for precise and convenient use.

[00134] It is manufactured from sustainable material: a tubular paperboard packaging made from environmentally friendly / biodegradable / recyclable and / or compostable materials, which have integrated barrier capabilities to ensure a long shelf life and product freshness without a perceptible impact on organoleptic properties.

[00135] It includes customizable features, especially a tubular cardboard packaging that can be customized to meet different types of products and customer needs, such as size, shape or color.

[00136] It features special high-barrier functionality against gas and moisture transfer through its walls. The packaging material that was developed provides high-barrier functional properties that enhance food protection and usability, such as oxygen transmission rate (OTR), moisture resistance (WVTR), and odor-blocking properties. Petition 870250094163, dated 10 / 15 / 2025, pp. 62 / 89 54 / 59

[00137] Optionally, but preferably, the packaging material is UV resistant or light-blocking, therefore of particular interest for packaging certain categories of food that are sensitive to UV.

[00138] Although resistant to stacking forces and mechanical stress from top loading (to which packages are subjected when transported and stored in stacks), tube-type packaging uses a paperboard material that is flexible enough to be folded or collapsed and therefore takes up less space after use when discarded.

[00139] The packaging according to the present invention is a shock absorption / damping system: the mechanical resilience of the current tube material and the free space that is integrated into the packaging cavity creates an air pocket feature, so as to protect sensitive products during transport or handling, against mechanical shocks.

[00140] The simple shape of this packaging creates a stackable design that minimizes product movement / optimizes shipping.

[00141] The fact that the paperboard material is used with a very high cellulose content creates a sound-dampening effect and reduces noise during transport and when opening, closing and resealing. This packaging is very easy to use in this regard.

[00142] The preferred shape and diameter of the tubes are chosen so that they adapt to the human hand for a highly ergonomic design and easy grip.

[00143] The invention includes the following aspects: 1. A packaging item comprising: - at least one container, preferably cylindrical, made of a multi-layered oxygen- and moisture barrier laminate comprising a paperboard layer and a barrier layer Petition 870250094163, dated 10 / 15 / 2025, pp. 63 / 89 55 / 59 organic, wherein the paperboard has a basis weight between 120 and 600 g / m2 and a cellulose content higher than 90%, preferably higher than 95%, more preferably higher than 99%, wherein the container includes at least one perimeter wall of the container and a container bottom closure system, which define at least one compartment for package contents and at least one dispensing opening configured to allow the package contents to be dispensed from the container through the dispensing opening, - at least one glove element with at least one peripheral wall of glove element, wherein the glove element is configured to slide over at least one top end portion of the container's peripheral wall, such that the peripheral wall of the glove element at least partially encloses the container's peripheral wall and the glove element at least partially covers the dispensing opening, wherein said glove element is preferably made of a multilayer oxygen- and moisture barrier laminate comprising a paperboard and an organic barrier layer, wherein the paperboard preferably has a basis weight between 120 and 600 g / m2 and a cellulose content higher than 90%, preferably higher than 95%, more preferably higher than 99%, and - optionally, at least one base element with at least one perimeter wall of the base element, wherein the base element at least partially encloses and, preferably, is fixed in an immovable manner to a bottom end portion of the perimeter wall of the container, wherein said base element is made of a paperboard with a basis weight between 120 and 600 g / m2 and a cellulose content higher than 90%, preferably higher than 95%, more preferably higher than 99%, of pre Petition 870250094163, dated 10 / 15 / 2025, pp. 64 / 89 56 / 59 reference, wherein the base element is made of a multilayer oxygen and moisture barrier laminate comprising said paperboard. 2.
