Description

[Technical Field]

[0001] This invention relates to packaged articles and packaged food products. [Background technology]

[0002] Packaging articles for packaging various types of contents are available in a variety of different shapes, sizes, and materials. For example, paper packaging articles are known from prior art and are often encouraged as being environmentally friendly and more sustainable compared to, for example, plastic.

[0003] However, existing paper packaging often does not provide the same level of protection for its contents as other materials such as plastic or glass. This can negatively impact one or more properties of the contents, for example, by shortening their shelf life.

[0004] Typically, oxidation and / or moisture absorption of packaged contents leads to a deterioration of the product's sensory properties, which is, of course, undesirable. In some cases, the movement of gases and / or moisture through the packaging walls can compromise food safety. Therefore, ensuring a packaging barrier against gases, especially oxygen, and moisture is of paramount importance, at least for sensitive food products.

[0005] Furthermore, existing paper packaging often suffers from lower structural stability compared to packaging made from other materials, such as plastic or glass. This can negatively impact the handling characteristics of the packaging.

[0006] U.S. Patent Application Publication 2017 / 0057687(A1), by Borer et al., discloses a container comprising an inner sleeve and an outer sleeve, one of which can slide into the other to open and close the container. The inner sleeve is printed with various things, and the outer sleeve has an opening that forms a window, so that the printed things on the inner sleeve are revealed when the outer and inner sleeves are moved relative to each other. The container disclosed therein can be made of any kind of material such as cardboard, but the application does not disclose a solution for preserving the contents against the interaction of oxygen or moisture. On the contrary, the reading window opened in the outer sleeve significantly reduces the possibility of securely protecting the contents when the container is closed. Furthermore, the container assembly offers little resistance to vertical stacking in an upright stacked position due to the fact that the compressive force applied to the container is supported only by the inner sleeve.

[0007] U.S. Patent Application Publication No. 2011 / 0204015(A1), a patent application by Westr et al., discloses a biodegradable jar with a cap. The jar wall is made of a permeable barrier material that prevents semi-solid contents from leaching through the jar wall, but the application does not disclose a barrier against the movement of oxygen and moisture, particularly after the initial opening (the so-called "shelf life after opening"), and the structure of U.S. Patent Application '015 requires the application of a complex capping solution to ensure adequate moisture and oxygen barriers at the interface between the jar and the cap. Furthermore, the container has moderate resistance to vertical stacking due to the fact that, in an upright stacked position, the compressive force is supported only by the jar wall.

[0008] U.S. Patent No. 2,377,471, by Williamson, discloses a classic box-shaped container including a supply opening located in one of the side panels. The container is an assembly of individual elements, each formed from a flat blank material. It 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.

[0009] Therefore, particularly in consideration of the above-mentioned drawbacks, an object of the present invention is to provide a packaging article that provides better protection for the contents within the package. A further object of the present invention is to provide a packaging article with improved handling characteristics and mechanical resistance characteristics. [Overview of the Initiative]

[0010] In a first aspect, the present invention relates to a packaged article.

[0011] This packaging article comprises at least one cylindrical container made of a multilayer oxygen-moisture barrier laminate comprising cardboard and organic and / or inorganic barrier layers. The cardboard is 120-600 g / m². 2 It has a basis weight and a cellulose content of more than 90%, preferably more than 95%, and more preferably more than 99%. The cylindrical container includes at least one container perimeter wall and a container bottom closure that define at least one compartment for packaging the contents.

[0012] In one preferred embodiment of the present invention, the container periwall can be made from a cellulose-based multilayer material having barrier properties against the movement of oxygen and / or moisture, and comprising at least the following layers from the inside (towards the inside of the container) to the outside, i.e. Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 At least one organic encapsulation layer coated in an amount of, Providing moisture barrier properties, selected from the list of metals, metalloids, or combinations thereof, and having a thickness of 1 to 100 nm, at least one inorganic barrier layer, Providing oxygen barrier properties, 0.5 to 20 g / m 2 In an amount of, preferably 1 to 10 g / m 2 In an amount of, more preferably 2 to 8 g / m 2 In an amount of, at least one organic barrier layer comprising a polymer selected from the list of polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butanediol vinyl alcohol copolymer (BVOH), or combinations thereof, Having a basis weight in the range of 30 to 120 g / m 2 Of a paper layer, Preferably polyvinyl acetate (PVAc), polyurethane (PU), acrylic, polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butanediol vinyl alcohol copolymer (BVOH), starch-based adhesives, modified cellulose-based adhesives, or a base compound selected from the list of combinations thereof, preferably an aqueous or solventless adhesive, an adhesive layer having a thickness preferably included in the range of 1 to 10 μm, 120 g / m 2 ~600 g / m 2 Of a paperboard layer or a cardboard layer having a basis weight in the range of, comprising.

[0013] The container further includes at least one supply opening configured to allow the packaged contents to be supplied from the container through the supply opening. The supply opening can be of the type that requires the package to be completely opened (typically, by removing at least one element from the rest of the package). Alternatively, or additionally, the package can include a second type of supply opening that does not require the package to be completely opened, particularly, for opening and closing the package, for example, by twisting, rotating, or basculating a part of the package relative to the rest of the package, a type of supply opening that only requires displacing one element relative to the rest of the package.

[0014] A multilayer oxygen-moisture barrier laminate comprising cardboard and organic and / or inorganic barrier layers increases the resistance of the container to oxygen and moisture movement, and therefore the resistance of the packaged article, compared to, for example, paper packaging articles known from the prior art. This improves the protection, preservation, and / or shelf life of the contents inside the container.

[0015] As understood in the context of the present invention, the “cylinder” preferably has a circular cross-section (i.e., “baseline”). However, other baselines (i.e., cross-sections), such as polygonal or elliptical, may also be considered “cylindrical” within the framework of the present invention. Preferably, the cylinder is an upright cylinder. However, an inclined cylinder is also conceivable.

[0016] As understood in the context of this invention, "cardboard" means 120 g / m² 2 ~600g / m 2 It is a cellulose-based flat structure consisting of one or more paper layers having a basis weight of 120 g / m2. Below 120 g / m2, the cellulose-based flat structure is considered under the term "paper" rather than cardboard in the context of this invention.

[0017] The packaging article further comprises at least one “upper” sleeve element having at least one sleeve element perimeter wall, the sleeve element being configured to slide on at least the upper end of the cylindrical container perimeter wall such that the sleeve element perimeter wall at least partially encloses the container perimeter wall and the sleeve element at least partially covers the supply opening. The sleeve element is made of a multilayer oxygen-moisture barrier laminate including at least cardboard and organic and / or inorganic barrier layers. The cardboard is 120-600 g / m². 2 It has a basis weight and a cellulose content of more than 90%, preferably more than 95%, and more preferably more than 99%. As described above, a multilayer oxygen-moisture barrier laminate comprising cardboard and an organic and / or inorganic barrier layer increases the container's resistance to the movement of oxygen and moisture.

[0018] The sleeve element is configured to slide on at least the upper end of the container wall such that the sleeve element's peripheral wall at least partially surrounds the container wall and the sleeve element at least partially covers the supply opening, thereby providing better protection for the contents inside the container. In particular, this provides at least double-wall protection for the packaged contents through the container wall and the sleeve element's peripheral wall. Furthermore, this allows the container's supply opening to be re-closed using the sleeve element after the initial opening, so as to maintain oxygen and moisture barrier properties.

[0019] Alternatively or additionally, such sleeve elements may be used for advertising and / or informational and / or aesthetic purposes, for example, by providing printing at least partially on the sleeve element, while the container may be primarily configured to protect and / or preserve the contents of the packaged article in a particularly hygienic and / or food-safe manner. For example, the container may not include printing, adhesives, etc. This minimizes the risk of printing colors or adhesives diffusing, for example, into the packaged contents (even if, for example, the barrier layer is very thin and / or the packaged contents are stored for a long period of time). This also allows the container and sleeve elements to be manufactured from different materials and / or different material compositions and / or different thicknesses. The sleeve element perimeter may completely enclose the container perimeter in a circumferential direction along a particular portion of the container's length.

[0020] The packaged article further comprises at least one “lower” base element having at least one base element perimeter wall, the base element at least partially enclosing the lower end of the container perimeter wall and optionally, but preferably, being immovably attached to the lower end of the container perimeter wall. The base element is 120-600 g / m 2 It is made of cardboard having a basis weight and a cellulose content of over 90%, preferably over 95%, and more preferably over 99%.

[0021] Preferably, but not required, the base element is made of a multilayer oxygen-moisture barrier laminate including the cardboard. The base element provides a support surface for placing the package on, for example, a tabletop. This allows the base element to be configured to primarily provide a reliable and robust interface between the package and an external surface, such as a tabletop. Preferably, the base element does not contain / storage any packaged contents. Preferably, the base element does not come into direct contact with the packaged contents of the package. This thus eliminates or at least reduces deformation of the base element caused by the packaged contents, thereby improving the stability of the package when placed on a surface by the base element. Preferably, the container bottom closure remains covered / sealed on the container during use of the package, i.e., at least until the packaged contents of the package are completely dispensed from the package.

[0022] Furthermore, each type of cardboard is 120-600 g / m² 2 By configuring the packaging to have a certain basis weight, the robustness and stability of the package are improved, particularly in the vertical or "axial" (upper load) direction. However, cardboard material is also particularly advantageous because it is sufficiently flexible, especially in the transverse direction, and can occupy less space when folded after use and disposed of for recycling. In particular, the container and / or sleeve elements and / or base elements are preferably dimensionally stable / rigid.

[0023] By constructing cardboard to have a relatively high cellulose content, for example, more than 90%, preferably more than 95%, and more preferably more than 99%, the density and / or manufacturing cost of the packaged article is reduced, and / or biodegradability and / or recyclability are improved, compared to materials with a lower cellulose content.

[0024] In one important aspect of the present invention, the sleeve element is sized and configured such that, when the packaging is in a fully closed configuration, the sleeve element overlaps the container element by at least 25 mm, preferably at least 50 mm, and more preferably at least 80 mm, depending on the dimensions of the container as disclosed below.

[0025] In another important aspect of the present invention, the sleeve element and the container element have functional play (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 attachment of the two in the closing configuration of the packaging without requiring complex capping such as threads or clipping mechanisms. By selecting functional play of preferably 50 to 500 μm, preferably 100 to 300 μm, the possibility of easily sliding the upper sleeve element over the core container element is ensured, while the adhesive force between the two elements is high enough that one element will not slide against the other unless an external force is applied.

[0026] The combination of functional play and overlap between the sleeve element and the container element ensures the airtightness of the packaging in a closed configuration, which enables the so-called "shelf life after opening." The shelf life after opening means that the packaging can be resealed after the first use once it has been opened, ensuring that the absorption of moisture and oxygen by the contents is severely limited.

[0027] A packaged article, more specifically a container, is configured to contain and / or store food material within its compartment, i.e., any material used as food, such as food / drinking ingredients, or used to make / produce food, for at least a certain period of time. The packaged material, e.g., food material, may be a liquid and / or solid substance. Preferably, the packaged material is solid and in a fluid form, particularly in powder form. The powder may have a range of particle size values, from small diameter particles to coarse diameter particles, or it may be a mixture of large and small diameter powder particles. The packaged material may also take the form of kibble or solid particle articles of various shapes and sizes, which may or may not be individually pre-packaged food. The types of food products can be wide-ranging, for example, coffee particles or solids, potato chips, chocolate solids, pet food kibble, compressed food articles such as compressed single-serving coffee, etc.

[0028] The components of the packaging article, such as containers, sleeve elements, and base elements, as specified above, may be provided in a range of 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 75 mm to 250 mm.

[0029] Preferably, the diameter of the element is such that it can be comfortably handled by the user's hand. The diameter is advantageously within the range of 20 to 200 mm, preferably 40 to 100 mm.

[0030] The supply opening may be located at the end of the container, for example, at the top end of the container. Alternatively, or additionally, the supply opening may be defined at least partially on the periphery of the container.

[0031] The container bottom closure can be a film and / or foil of a metallized material, such as a metal like aluminum, or a metallized plastic such as metallized paper or metallized polyolefin, preferably metallized polypropylene or metallized polyethylene terephthalate (PET), with a thickness of preferably 5 to 30 μm, more preferably 10 to 15 μm. Alternatively or additionally, the container bottom closure may be made of a layer of a non-metallized plastic, such as a polymer like polyethylene terephthalate (PET), or a polyolefin like polyethylene (PE), with a thickness of 20 to 60 μm.

[0032] The content of the aforementioned materials, such as the cellulose content, is determined as a weight percentage of the total weight of each material.

[0033] Preferably, at least a portion of the base element protrudes from the container beyond the container bottom closure. Therefore, when the container is placed upright on a surface (e.g., a tabletop) and the base element is placed on the surface, the base element can separate the container bottom closure from the surface. This prevents mechanical damage to the container bottom closure. Furthermore, this makes it possible to support the packaged article well on the surface, substantially independently of the condition of the container bottom closure, even if the container bottom closure is deformed, for example, if it bulges due to the weight and / or volume of the packaged contents inside the container.

[0034] Preferably, the packaged article further includes at least one overhanging shelf portion. When the sleeve element slides over the container, the sleeve element, preferably the lower end of the sleeve element, may be configured to at least partially abut the overhanging shelf portion. Preferably, the overhanging shelf portion is defined at the interface between the base element and the container. In other words, the overhanging shelf portion may be used as a fastener for the sleeve element, thereby enabling the user to close the packaged article more easily, more intuitively, and / or more securely. Furthermore, the overhanging shelf portion may provide the user with tactile and / or optical feedback to ensure that the container is properly and securely closed by the sleeve element. The overhanging shelf portion may be provided by dimensioning the base element wider than the container, at least in the direction in which the overhanging shelf portion extends, for example, by configuring the base element to have a larger diameter than the container.

[0035] Preferably, the overhanging shelf portion can be defined at least partially by the upper end of the base element, and preferably at least partially by the upper end of the peripheral wall of the base element. In other words, the lower end of the sleeve element may be positioned and / or in contact with the upper end of the peripheral wall of the base element, at least partially, when the sleeve element slides over the container. Preferably, the shape and / or size of the upper end of the base element, for example, its circumference, may substantially match the shape and / or size of the lower end of the sleeve element.

[0036] When the packaged article is in a fully closed configuration, the force exerted vertically by the contact features of the base element in contact with the sleeve element is distributed across three contact points, namely, A first contact point 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 contact point at the interface between the lower edge of the cylindrical container (and the lower closing portion of the cylindrical container) and the inner surface of the base element, The third contact point between the lower edge of the sleeve element and the upper edge of the base element, and the holding by this third contact point, ensure that the mechanical resistance of the packaged article to upper loads (i.e., vertical or "axial") is guaranteed.

[0037] In this configuration, the three components of the packaging article—the container, sleeve element, and base element—all support the stacking force applied axially (perpendicularly) to the packaging article. Therefore, the compressive force applied individually to each element of the packaging article is reduced, and the integrity of each of the container, sleeve element, and base element is maintained. The overall mechanical resistance of the packaging article can be maintained even if the amount of material used to make each of these elements is reduced.

[0038] In this way, the stacking capacity of the entire packaged goods is guaranteed, ensuring that the integrity of each individual package is not affected when such a large number of packages are stacked on top of each other for transport or storage.

[0039] Preferably, the sleeve element and / or base element are "cylindrical." More preferably, the sleeve element and / or base element are formed as cylinders having a circular baseline (i.e., "cross-section"). The inner diameter and / or outer diameter of the cylinder forming the sleeve element and the cylinder forming the base element may be the same. Within the framework of this specification, "cylindrical" means that the container, sleeve element and / or base element may be formed as cylinders having an elliptical or polygonal cross-section.

[0040] Preferably, the sleeve element and / or container are configured such that the sleeve element can be removed from the container and slid over the container multiple times. This allows the container to be opened and closed multiple times by the sleeve element.

[0041] Preferably, the packaging article further includes at least one container lid, preferably configured to seal so as to close a supply opening at the upper edge of a cylindrical container, in order to prevent the packaged contents from being supplied through the supply opening. Preferably, the container lid is at least partially removable and preferably peelable from the supply opening.

[0042] In one embodiment, the upper edge of the container perimeter wall may have an inwardly inclined portion oriented toward the interior of the container. Inside the container, below the inwardly inclined portion, an annular ring (or "collar" or "washer") is sealed. The annular ring may be a flat ring with an inclined outer portion around its circumference. The outer diameter and width of the annular ring are such that at least the inclined outer portion of the annular ring radially overlaps with the inwardly inclined portion of the container, enabling a proper seal between them. Preferably, the radial overlap between the inclined portion of the annular ring and the inclined portion of the upper edge of the container is 1 to 10 mm, more preferably 3 to 7 mm wide. The innermost flat portion of the annular ring protrudes inward from the inclined portion of the container, thus leaving an inward sealing surface of the annular ring, which is sufficient to properly seal the top lid of the container. Preferably, the inward sealing surface of the annular ring is 1 to 5 mm, more preferably 2 to 3 mm wide. The inclined portion of the annular ring has the effect of rigidifying the ring in the axial and radial directions. Similarly, the inwardly inclined portion of the upper edge of the container stiffens this portion of the container in both the radial and axial directions. "Axial direction" is conventionally defined as the direction aligned with the vertical axis of symmetry of the packaged article, while "radial direction" is defined as the direction aligned in a plane generally perpendicular to the axial direction. By sealing these two inclined portions, the sealing portion between the annular ring and the container wall is provided with good resistance to mechanical deformation in the axial and, more importantly, radial directions.

[0043] The annular ring can be manufactured from roll paper, cardboard, metal, plastic such as biodegradable or recyclable polymers, or a combination thereof. In a preferred embodiment, the annular ring is manufactured from multilayer cardboard having barrier properties against the movement of oxygen and / or moisture. More precisely, in such a preferred embodiment, the annular ring is a flat ring, from top to bottom (towards the inside of the container), consisting of at least the following layers, i.e., Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2Amount, preferably 4-9 g / m 2 At least one organic encapsulation layer coated in an amount of, A moisture barrier is provided, comprising at least one inorganic barrier layer selected from a list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, It provides oxygen barrier properties, 0.5-20 g / m² 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 At least one organic barrier layer comprising an amount of a polymer selected from the list of polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), or combinations thereof, 30-120g / m 2 A paper layer having a basis weight in the range of, An adhesive layer, preferably a water-based or solvent-free adhesive, having a base compound selected from the list of polyvinyl acetate (PVAc), polyurethane (PU), acrylic, polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), starch-based adhesive, modified cellulose-based adhesive, or combinations thereof, wherein the adhesive layer has a thickness preferably in the range of 1 to 10 μm. 120g / m 2 ~600g / m 2 It comprises a cardboard layer or thick paper layer having a basis weight in the range of [specified range].

[0044] The oxygen and / or moisture barrier properties achieved by the annular ring are preferably similar to those of the material used to manufacture the container perimeter. The overlap of the seal between the container and the ring, and the orientation of the layers in each of these two elements, ensure proper continuity of the barrier properties in the sealed zone. In this regard, it is also preferable that the cellulose layer of the container perimeter (e.g., paper, cardboard, thick paper) is oriented outward, while the organic and inorganic barrier layers and sealing layer are oriented inward, or conversely, that the barrier and sealing layers of the annular ring are oriented outward, with its cellulose layer oriented inward (in contact with the container contents). The annular ring ensures proper continuity of the oxygen and / or moisture barrier properties between the container and the container lid.

[0045] Preferably, the container lid is sealed along the entire circumference of an annular ring that protrudes inward from the inclined portion of the container. As described above, the role of the annular ring is to mechanically reinforce the rigidity of the container in the opening region so that radial forces applied to the container wall in the upper region of the container do not cause deformation of the container.

[0046] The upper part of the container's peripheral wall surrounding the supply opening, due to its sloping contour, also facilitates the insertion of the container into the sleeve element, thereby promoting the re-closing of the packaged item. This is particularly important since the packaged item is designed to be opened and closed multiple times.

[0047] The container lid may be a film and / or foil of a metallized material, such as a metal such as aluminum, or a metallized plastic such as metallized paper or metallized polyolefin, preferably metallized polypropylene. Alternatively or additionally, the container lid may be made of a plastic, such as a polymer such as polyethylene terephthalate (PET).

[0048] In one embodiment, the top lid is a multilayer film comprising an aluminum foil layer preferably 20-60 μm thick and a sealable plastic layer, such as a polyolefin layer (e.g., high-density polyethylene (HDPE)), bonded to the aluminum foil layer with an adhesive. The thickness of the sealable plastic layer is preferably 10-40 μm, more preferably 20-30 μm. The advantage of such a peelable aluminum foil film is that it achieves extremely high barrier properties against oxygen and moisture transfer. The measured oxygen permeability (OTR) and water vapor permeability (WVTR) values ​​for this type of aluminum film are so low that they are almost immeasurable, and therefore are considered the industry standard in terms of barrier efficiency.

[0049] However, in alternative embodiments, to ensure a high cellulose content for the recyclability of the packaged article, the lid may be made of a paper-based membrane that is recyclable in a paper stream process and heat-sealable or ultrasonically sealed. In this sense, the membrane may contain at least 90% cellulose fibers. In such cases, it may include at least one very thin layer of organic and / or inorganic material attached to the paper layer to provide barrier properties against oxygen and / or moisture, similar to the barrier properties of the container perimeter. In preferred embodiments of the present invention, the membrane is made of the following layers, in order from the outside to the inside (the inside being the side in contact with the contents of the container): 30-120g / m 2 A paper layer having a basis weight in the range of, 0.5~20g / m 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 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 combinations thereof, in an amount thereof, A minimum of one inorganic barrier layer selected from the list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 It comprises at least one organic sealing layer coated in an amount of , and

[0050] Generally, the inorganic layer provides a barrier against moisture (i.e., water vapor) movement, while the organic layer provides a barrier against oxygen movement.

[0051] The peelable film is preferably attached to the periphery of the container by a heat-sealing process, but alternatives such as ultrasonic sealing processes can also be used.

[0052] In other words, the container lid can provide a moisture and oxygen barrier, which is removable when the consumer first opens the packaged goods (for example, after removing the sleeve element). The container opening may then be reclosed by sliding (or re-sliding) the sleeve element over the container. After the container lid is removed during the first use of the packaged goods, it is the sleeve element that can provide oxygen and / or moisture barrier properties to the packaged goods.

[0053] The container further includes a container bottom closure (or "container bottom wall") preferably made of a material that achieves oxygen and / or barrier properties similar to those of the material used to form the container wall.

[0054] In one embodiment, the container bottom closure may be a multilayer foil comprising a first layer of metallized polyethylene terephthalate (PET) having a thickness of 12 μm attached to a second layer of polyethylene (PE) having a thickness of 40 μm. The polyethylene layer provides good sealing properties for sealing the bottom of the container to the lower edge of the container's peripheral wall.

[0055] Alternatively, the lower part of the container may be made from a multilayer cellulose material having oxygen and / or moisture barrier properties. In one embodiment, the multilayer material has at least the following layers from the outside to the inside (towards the interior of the container): Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 At least one organic encapsulation layer coated in an amount of, A moisture barrier is provided, comprising at least one inorganic barrier layer selected from a list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, It provides oxygen barrier properties, 0.5-20 g / m² 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 At least one organic barrier layer comprising an amount of a polymer selected from the list of polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), or combinations thereof, 30-120g / m 2 A paper layer having a basis weight in the range of, An adhesive layer, preferably a water-based or solvent-free adhesive, having a base compound selected from the list of polyvinyl acetate (PVAc), polyurethane (PU), acrylic, polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), starch-based adhesive, modified cellulose-based adhesive, or combinations thereof, wherein the adhesive layer has a thickness preferably in the range of 1 to 10 μm. 120g / m 2 ~600g / m 2 It comprises a cardboard layer or thick paper layer having a basis weight in the range of [specified range].

[0056] Preferably, the outer surface of the peripheral portion of the container bottom closure is sealed onto the inner surface of the container periphery by a heat sealing process.

[0057] The base element includes a base element lower closure portion that at least partially covers the surface of the lower opening of the base element.

Alternatively, or additionally, the lower closure of the base element may be made of plastic, such as a polymer such as polyethylene terephthalate (PET).

[0060] In one embodiment, the films and / or foils that can be attached to the outer surface of the base element wall and the outer surface of the lower closing portion are arranged in the following order from outside to inside (the inside being the side in contact with the outer surface of the base element wall and the lower closing portion): 30-120g / m 2 A paper layer having a basis weight in the range of, 0.5~20g / m 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 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 combinations thereof, in an amount thereof, A minimum of one inorganic barrier layer selected from the list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 It comprises at least one organic sealing layer coated in an amount of , and

[0061] The additional membrane serves to protect the sealing edge between the bottom wall and the lower closure from scratching or accidental delamination.

[0062] Preferably, a similar configuration is applied to the sleeve element.

[0063] Generally, the components of the packaging according to the present invention are selected from a plurality of packaging materials that contain a high content of cellulose and have barrier properties against oxygen and moisture. Such barrier properties are achieved by incorporating organic and / or inorganic layers into the packaging material structure and measuring at 23°C and 50% relative humidity (RH) at 1 cm². 3 / m 2 Less than 0.5 cm per day, preferably 0.5 cm 3 / m 2 The oxygen permeability (OTR) value is less than 1 g / m² when measured at 23°C with 85% RH. 2 Less than 0.5 g / m² per day, preferably 0.5 g / m² 2 This is achieved by providing a water vapor transmission rate (WVTR) value of less than 1 / day, among other things.

[0064] Preferably, the packaged contents are a bulk solid, preferably a fluid bulk solid, preferably a fluid powder. The powder may contain granules and / or particles. Preferably, the packaged contents are coffee powder, preferably soluble and / or freeze-dried coffee powder, or milk powder.

In other words, the sleeve element periphery may extend axially beyond the container periphery by the values ​​described above.

[0067] Preferably, when the sleeve element slides over the container, the sleeve element and the container are configured to be frictionally connected, preferably by friction between at least the container wall and the sleeve element wall. This provides a relatively robust connection and / or seal between the sleeve element and the container. This extends the shelf life of the contents in the packaged article. Furthermore, this prevents the sleeve element from accidentally detaching from the container, for example, when a user grasps only the sleeve element and lifts the package by the sleeve element.

[0068] Preferably, when the sleeve element slides over the container, the peripheral wall of the sleeve element overlaps the container peripheral wall axially along at least 50%, preferably at least 60%, and more preferably at least 70% of the axial length of the container. This length is thought to provide a proper frictional connection between the sleeve element and the container, and adequate moisture and oxygen barrier properties for keeping the packaged contents fresh.

[0069] Preferably, the base element periphery overlaps the container periphery axially along at least 5%, preferably at least 10%, more preferably at least 20%, and more preferably at least 30% of the axial length of the container.

The opening may function as a vent, allowing gas to enter and exit the packaged article through the vent when the sleeve element is open. This allows the pressure inside the packaged article to be at least partially equalized with the environment, thereby facilitating the removal of the sleeve element. Alternatively, or additionally, the opening may be configured as a spout, allowing the packaged contents to be supplied through the spout after the sleeve element has been slid upward and / or away from the base element.

[0072] Preferably, the container is free of printing and / or labels, and optionally, the sleeve element and / or base element may be printed at least along the outer surface of their respective peripheral walls.

[0082] ​This embodiment of the first and second preferred packaging structures gives the outer surface of the packaged article a metallic appearance. In this case, the cellulose layer is therefore oriented inward of the packaged article and is not visible from the outside when the packaged article is closed.

[0083] In preferred embodiments where the peripheral walls of the container, sleeve element, and base element are formed in a cylindrical shape, these are preferably manufactured by rolling a flat material into a tube and seaming the longitudinal edges of the tube in an "edge-to-edge" configuration (i.e., without overlapping the edges) using a flat seaming strip applied to at least one side of the tube.

[0088] Figures 1 and 2 show a packaged article 100, which includes a cylindrical container 102 made of a multilayer oxygen-moisture barrier laminate. The multilayer oxygen-moisture barrier laminate includes cardboard, an organic barrier layer, and an inorganic barrier layer. The cardboard has a weight of 120-600 g / m². 2 It may have a basis weight and / or a cellulose content of more than 90%, preferably more than 95%, more preferably more than 99%. More precisely, preferably, the container perimeter wall can be made from a cellulosic multilayer material having barrier properties against the movement of oxygen and / or moisture, and consisting of at least the following layers from the inside (towards the inside of the container) to the outside, i.e., Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 At least one organic encapsulation layer coated in an amount of, A moisture barrier is provided, comprising at least one inorganic barrier layer selected from a list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, It provides oxygen barrier properties, 0.5-20 g / m² 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 At least one organic barrier layer comprising an amount of a polymer selected from the list of polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), or combinations thereof, 30-120g / m 2 A paper layer having a basis weight in the range of, An adhesive layer, preferably a water-based or solvent-free adhesive, having a base compound selected from the list of polyvinyl acetate (PVAc), polyurethane (PU), acrylic, polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH), butenediol vinyl alcohol copolymer (BVOH), starch-based adhesive, modified cellulose-based adhesive, or combinations thereof, wherein the adhesive layer has a thickness preferably in the range of 1 to 10 μm. 120g / m 2 ~600g / m 2 It comprises a cardboard layer or thick paper layer having a basis weight in the range of [specified range].

[0089] The container 102 includes a container perimeter wall 104 and a container bottom closure (or "container bottom wall") 106 that define at least one compartment 108 for packaging contents such as food materials. The container 102 further includes a supply opening 110 configured to allow the packaged contents to be supplied from the container 102 through the supply opening 110.

[0090] In one preferred embodiment shown in Figure 1, the container bottom wall 106 is a multilayer foil comprising a first layer of metallized polyethylene terephthalate (PET) having a thickness of 12 μm attached to a second layer of polyethylene (PE) having a thickness of 40 μm. The polyethylene layer provides good sealing properties for sealing the container wall to the lower part of the container perimeter wall.

[0091] The packaged article 100 further comprises a sleeve element 114 having a sleeve element peripheral wall 116. The sleeve element further comprises a sleeve element top wall 150, shown in Figure 1, which at least partially closes the upper end of the sleeve element.

[0092] The sleeve element 114 is configured to slide on at least the upper edge 118 of the container wall 104 such that the sleeve element peripheral wall 116 at least partially surrounds the container wall 104 and the sleeve element 114 at least partially covers the supply opening 110. The sleeve element 114 may be made of a multilayer oxygen-moisture barrier laminate comprising cardboard and an organic barrier layer. The cardboard may be 120-600 g / m². 2 The basis weight and / or cellulose content may be greater than 90%, preferably greater than 95%, and more preferably greater than 99%.

[0093] The packaged article 100 further comprises a base element 122 having a base element perimeter wall 124. The base element 122 comprises a base element bottom wall (or lower "closure") 160, which at least partially closes the lower end of the base element. The base element 122 at least partially surrounds the lower end 128 of the container perimeter wall 104 and is preferably (but not strictly required) attached thereto so as not to move. In other words, the base element 122 slides at least partially on the container perimeter wall 104 and may optionally, but preferably, be firmly attached to the container perimeter wall. The base element 122 is 120-600 g / m 2 The base element 122 may be made of cardboard having a basis weight and / or a cellulose content of more than 90%, preferably more than 95%, and more preferably more than 99%. The base element 122 may be made of cardboard and, optionally, a multilayer oxygen-moisture barrier laminate including an organic barrier layer.

[0094] The packaged article 100 further includes a container lid 132, preferably configured to seal tightly, to close the supply opening 110 so that the packaged contents are not supplied through the supply opening 110. The container lid 132 may be sealed (e.g., by heat sealing, adhesive, and / or welding) to the upper end (i.e., upper edge) portion 118 of the container perimeter wall, particularly around the supply opening 110, but alternatively, and preferably, the lid 132 may also be sealed to a ring (or "collar" or "washer") 180 attached to the upper end (i.e., upper edge) portion 118 of the container perimeter wall, as shown in Figures 3, 9A and 9B. The container lid 132 is at least partially removable from the supply opening 110, for example, when the container 102 is first opened. Once the container lid 132 is removed at least partially from the supply opening 110, the container 102, and more specifically the supply opening 110, may be closed and reopened, preferably multiple times, by sliding the sleeve element 114 over the container 102 and removing it therefrom.

[0095] The packaged article 100 further includes a second opening 140 defined in the sleeve element perimeter wall 116. The second opening 140 may be configured to be reclosed at least partially, preferably multiple times. The second opening 140 is closed by the container perimeter wall when the sleeve element 114 is slid over the container 102, for example when it is fully slid over it, and / or the second opening 140 may be opened and reclosed by the rotation of the sleeve element 114 relative to the container 102 (for example, by providing a notch along a portion of the container perimeter wall 104 configured to overlap the second opening 140 when the second opening 140 is open).

[0096] The second opening 140 may be configured to function as a vent, allowing gas to enter and exit the packaged article 100 through the vent while the sleeve element 114 is being opened and / or before it is being opened. Alternatively, or additionally, preferably, the opening may function as a spout, allowing contents to be supplied through the spout after the sleeve element 114 has been slid upward and / or away from the container 102.

[0097] In an optional embodiment, an element 142 may be displaceable to return toward the second opening 140, preferably via interaction between the sleeve element 114 and the container 102 while the sleeve element 114 is slid onto or further onto the container 102. This allows the displaceable element 142 to at least partially reclose the second opening 140.

[0098] Preferably, the cylindrical container 102 has no 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] The packaged article 100 further includes an overhanging shelf portion 146. The overhanging shelf portion 146 is defined by the end portion 147 of the base element 122, in particular by the distal edge portion 148 of the base element peripheral wall 124. As shown in Figure 2, the sleeve element 114 is configured to at least partially contact the overhanging shelf portion 146 when it slides over the container 102.

[0100] More precisely, when the packaged article is in a fully closed configuration, the force exerted vertically by the contact features of the base element in contact with the sleeve element is applied to three contact points, namely, A first contact point 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 contact point at the interface between the lower edge of the cylindrical container (and the lower closing portion of the cylindrical container) and the inner surface of the base element, A third contact point between the lower edge of the sleeve element and the upper edge of the base element, and the fact that the packaged article is held by this third contact point ensures that the mechanical resistance of the packaged article to upper loads (i.e., vertical loads) is guaranteed.

[0101] In this way, the stacking capacity of the entire packaged goods is guaranteed, ensuring that the integrity of each individual package is not affected when such a large number of packages are stacked on top of each other for transport or storage.

[0102] Figure 3 shows an enlarged view of the container lid 132 of the packaged article 100 in Figures 1 and 2. As schematically shown in Figure 3, the container lid 132 is attached to the annular ring (or "collar" or "washer") 180 of the container 102, preferably sealed, preferably adhesively. The container lid 132 may be configured to be peeled off from the annular ring 180, particularly from the annular ring 180, and / or the container lid 132 may be puncturable to at least partially open the supply opening 110. The annular ring 180 may be made of cardboard. Alternatively, the annular ring 180 may be formed as part of the container periphery 104. As described above, the main role of the annular ring 180 is to mechanically reinforce the rigidity of the container 102 in the area of ​​the supply opening 110 so that radial forces applied to the container wall in the upper region of the container do not cause deformation. Furthermore, the annular ring 180 is preferably made from a material having barrier properties against the movement of oxygen and moisture, thereby enabling the continuity of the oxygen and / or moisture barrier between the container 102 and the container lid 132.

[0103] Figures 4 to 6 schematically show different embodiments for constructing the container bottom closure 106. As schematically shown in Figure 4, for example, the lower closure 106 may be attached to the inside 154 of the container peripheral wall 104, preferably in a sealed manner, and preferably by adhesive.

[0104] As schematically shown in Figure 5, the lower closure 106 may be attached to a flared portion 158 of the container 102 that extends outward, particularly radially outward, away from the compartment 108. The flared portion 158 extends axially away from the supply opening 110.

[0105] As schematically shown in Figure 6, the lower closure 106 may be attached to a portion 160 of the container 102, which extends outward, particularly radially outward, away from the compartment 108 and axially toward the supply opening 110.

[0106] As shown in Figures 7A and 7B, the packaging may have a dispensing opening 170 on the side of the sleeve element 114. By lifting the sleeve element 114 (without removing it from the rest of the packaging), a passage is formed between the internal compartment of the packaging and the dispensing opening 170, creating a passage for the product. The diameter of the dispensing opening (ranging from 5 mm to 30 mm) is sufficient to dispense some product in a measured quantity and flow rate, thereby allowing for convenient dispensing of the product as shown in Figure 7B. After dispensing, the sleeve element 114 is pushed back onto the rest of the packaging to close the packaging.

[0107] Figures 8A and 8B show two alternative configurations for the structure of the sleeve element 114 and / or the base element 122.

[0108] As described above, the base element 122 comprises a base element peripheral wall 124 and a base element bottom wall 160 that at least partially covers the surface of the lower opening of the base element. The sleeve element 114 comprises a sleeve element peripheral wall 116 and a sleeve element top wall 150 that at least partially closes the upper end of the sleeve element.

[0109] In one embodiment, the peripheral wall of the base element may be made of a cellulosic (e.g., paper-based or cardboard-based) material to which at least one layer of oxygen and / or moisture barrier material is attached. The oxygen and / or moisture barrier material may include at least one organic and / or inorganic layer. At least one oxygen and / or moisture barrier layer may be attached to the cellulosic layer by extrusion, lamination, or an aqueous dispersion process. In the case of an inorganic layer, it may be deposited as an ultrathin layer with a thickness in the nanometer range by a vacuum deposition process.

[0110] In one embodiment shown in Figure 8A, the peripheral walls of the base element and sleeve element are manufactured from a multilayer packaging material structure, the structure being arranged from the outside inward, namely, 120g / m 2 ~600g / m 2 A paperboard layer having the basis weight, 0.5~10g / m 2 An optional adhesive layer having the basis weight, 30-120g / m 2 A paper layer having the basis weight, 0.5~20g / m 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 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 combinations thereof, in an amount thereof, A minimum of one inorganic barrier layer selected from the list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, Made from polyolefins grafted with acrylic acid or methacrylic acid polymer, or at least one ionomer (preferably sodium ionomer), preferably ethylene acrylic acid or methacrylic acid ionomer, in an amount of 2 to 20 g / m2, preferably 4 to 9 g / m2. 2 It comprises at least one organic heat seal layer applied in an amount of .

[0111] The inorganic layer may contain a metal or metalloid selected from the list of aluminum, aluminum oxide (AlOx), or silicon oxide (SiOx), and such metal and / or metalloid is deposited by either vacuum deposition or transfer metallization.

[0112] In this embodiment schematically shown in Figure 8A, the group of barrier layers 190, particularly the metallized layer, is oriented toward the inside of the container (and is not visible from the outside when the packaged article is closed), while the cellulose (cardboard, paper) layer 200 is oriented toward the outside of the container.

[0113] In an alternative embodiment of the present invention shown in Figure 8B, the order of the peripheral wall layers is reversed compared to the aforementioned first embodiment shown with reference to Figure 8A. In this alternative embodiment, the group of barrier layers 190, particularly including the metallized layer, is oriented outward, while the cellulose (cardboard, paper) layer 200 is oriented inward. In this configuration, the packaged article 100 has a metallic appearance when viewed from the outside, particularly when the packaged article 100 is closed. This alternative embodiment provides an outer surface of the packaged article that has a very smooth surface, even at the microscopic level, due to the metallized layer and the outermost organic heat-seal layer. Such a smooth surface is advantageous and therefore preferable when printing is applied to the outer surface of the base element 122 and / or the outer surface of the sleeve element 114. This makes it possible to use flexographic printing technology, which is less expensive than the digital printing technology that is usually required to print on the surface of rough cardboard or paper.

[0114] In both embodiments described above with reference to Figures 8A and 8B, the base element bottom wall 160 and the sleeve element top wall 150 can be made of the same material as the periphery walls of the base element and sleeve element to which they are attached. The sleeve element top wall 150 comprises a flat disc having a slightly downwardly inclined outer peripheral portion 151, as shown in Figures 8A and 8B. The upper portion 152 of the sleeve element periphery wall 114 is also inclined toward the internal volume of the sleeve, so that the inclined portions 151 and 152 of both elements can overlap and be sealed together, as shown in Figures 8A and 8B.

[0115] In the embodiments shown in Figures 8A and 8B, an additional film 210 can be attached to the outer surface of the inclined portion 152 of the sleeve element peripheral wall and the outer surface of the top wall 150. The additional film 210 is arranged in the following layers, from outside to inside (the inside being the side in contact with the outer surfaces of the sleeve element peripheral wall 116 and the top wall 150): 30-120g / m 2 A paper layer having a basis weight in the range of, 0.5~20g / m 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 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 combinations thereof, in an amount thereof, A minimum of one inorganic barrier layer selected from the list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, It is made of acrylic or methacrylate ionomer, preferably ethylene acrylic or methacrylate ionomer, and is 2-20 g / m². 2 Amount, preferably 4-9 g / m 2 It comprises at least one organic sealing layer coated in an amount of , and

[0116] The additional membrane serves to protect the sealing zone 220 between the peripheral wall of the sleeve 116 and the top lid 150 from scratching or accidental delamination. Furthermore, in the embodiment shown in Figure 8B, when the peripheral wall of the sleeve 116 is made of a material in which the cellulose layer is oriented inward towards the packaged article and the oxygen and / or barrier layer is oriented outward, it has been found that the oxygen and / or moisture barrier properties in the sealing zone 220 may be reduced due to the fact that sealing occurs between the innermost cellulosic layer 200 of the sleeve peripheral wall and the outermost cellulosic layer of the sleeve top lid 150. In that case, it has been found that a membrane 210 including at least one layer made of oxygen and / or moisture barrier material, in particular as described above, can provide additional oxygen and / or barrier protection to protect the contents of the packaged article. This additional protection is due to the fact that the organic and inorganic barrier layers of the membrane 210 are positioned adjacent to the organic and / or inorganic barrier layer 190 of the peripheral wall 116 of the sleeve 114.

[0117] The same structure applies to the base element 122 and the base element closing section (or "wall") 160 attached thereto.

[0118] Figures 9A and 9B schematically show one embodiment of the packaged article 100 according to the present invention. Figure 9A is an exploded view of the various components described above, and Figure 9B shows the packaged article 100 in a fully closed configuration.

[0119] The container 102 is manufactured from a cylindrical tube that forms the container perimeter wall 104. The lower part of the container perimeter wall 104 is closed by the container bottom wall 106, and the upper part of the container perimeter wall 104 is closed by a peelable membrane 132 via an annular ring 180 that forms an interface between the membrane 132 and the container perimeter wall 104. The internal volume of the container 102 defines a compartment 108 for containing the product.

[0120] The upper sleeve element 114 is manufactured from a cylindrical tube that forms the sleeve perimeter wall 116, and has an inner diameter that allows it to frictionally slide over the container perimeter wall 102 to open and close the packaged article 100. The upper part of the sleeve perimeter wall 104 is closed by the sleeve top wall 150, which is covered on the outside by a membrane 210 that overlaps with the sealing zone between the sleeve top wall 150 and the sleeve perimeter wall 102.

[0121] The base element 122 is manufactured from a cylindrical tube that forms the base element perimeter wall 124, and has an inner diameter such that it can be positioned on the container perimeter wall 102 by friction. The lower part of the base element perimeter wall 124 is closed by the base element bottom wall (or "closure") 160, and its outside is covered by a membrane 210 that overlaps with the sealing zone between the base element bottom wall 160 and the base element perimeter wall 124. Preferably, the base element 122 is permanently attached on the container 102.

[0122] The peripheral walls 104, 116, and 124 of the container, sleeve element, and base element, as well as the bottom wall 160 of the base element and the top wall 150 of the sleeve element, may be manufactured from a multilayer packaging material structure, which consists of the following layers from the outside inward: 120g / m 2 ~600g / m 2 A paperboard layer having the basis weight, 0.5~10g / m 2 An optional adhesive layer having the basis weight, 30-120g / m 2 A paper layer having the basis weight, 0.5~20g / m 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 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 combinations thereof, in an amount thereof, A minimum of one inorganic barrier layer selected from the list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, It is made of polyolefin acrylic acid or methacrylic acid polymer or grafted ionomer (preferably sodium ionomer), preferably ethylene acrylic acid or methacrylic acid ionomer, and is 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 It comprises at least one organic heat seal layer applied in an amount of .

[0123] The inorganic layer may contain a metal or metalloid selected from the list of aluminum, aluminum oxide (AlOx), or silicon oxide (SiOx), wherein the metal and / or metalloid is deposited by either vacuum deposition or transfer metallization.

[0124] The film 210 may be manufactured from a multilayer material, which has the following layers in order from the outside to the inside (the inside being toward the inside of the packaged article): 30-120g / m 2 A paper layer having a basis weight in the range of, 0.5~20g / m 2 Amount, preferably 1-10 g / m 2 Amount, more preferably 2-8 g / m 2 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 combinations thereof, in an amount thereof, A minimum of one inorganic barrier layer selected from the list of metals, metalloids, or combinations thereof, having a thickness of 1 to 100 nm, Made from ethylene acrylic or methacrylate ionomer, 2-20 g / m² 2 Amount, preferably 4-9 g / m 2 It comprises at least one organic sealing layer coated in an amount of , and

[0125] In the embodiments shown in Figures 9A and 9B, the material for forming the peripheral walls of the sleeve element 114 and the base element 122 may therefore include a layer of cellulose 200 facing the outside of the packaged article 100, and the organic and / or inorganic barrier layer 190 against the movement of oxygen and / or moisture is oriented to face the inside of the packaged article 100. As a result, in the embodiments shown in Figures 9A and 9B, the appearance of the closed packaged article 100 is that of a cellulose-based (paper or cardboard) package.

[0126] However, the materials of the peripheral walls of the sleeve and base elements can be reversed so that the appearance of the packaging can be that of metallized packaging.

[0127] The sleeve element and the base element may have the same height, or they may have different heights. However, in a very preferred embodiment of the present invention, the heights of the sleeve and base element are selected such that, in the closed configuration of the packaged article, as shown in Figure 9B, the lower edge of the sleeve element 114 contacts the overhanging shelf portion 146 of the base element 122, the inner surface of the top wall 150 of the sleeve element contacts the top surface of the container, and the inner surface of the bottom wall 160 of the base element contacts the bottom surface of the container 102.

[0128] Various aspects and embodiments of the present invention have been described for illustrative purposes. However, the present invention should not be unduly limited by any of the details of the above disclosure, and those skilled in the art will understand that modifications and alterations not inconsistent with the principles of the present invention may be made and still fall within the scope of the invention. In particular, the present invention should not be construed as being limited to the embodiments described above with reference to the drawings. Rather, the scope of protection of the present invention is determined solely by the appended claims and their equivalents.

[0129] In general, the packaging according to the present invention provides users with several advantages and benefits, as follows:

[0130] This packaging offers a unique structural design using cardboard packaging with a distinctive tube shape and size, and its structure is made from recyclable cardboard throughout the paperstream process.

[0131] This packaging features a tube packaging with an innovative closure system, namely a novel "lift and push" mechanism for the closure that allows for user-friendly opening, closing, and resealing (easy to seal and reseal, while simultaneously being safe and protective). In particular, the sole attachment of the upper sleeve element to the core container is performed by sliding one over the other. The functional play between the two is sufficient to ensure proper attachment, thus eliminating the need for complex capping such as threads or clipping mechanisms. By selecting a functional play of preferably 50 to 500 μm, preferably 100 to 300 μm, the possibility of easily sliding the upper sleeve element over the core container element is ensured, while the adhesive force between the two elements is high enough to prevent one element from sliding against the other without the application of an external force. "Functional play" refers to the difference between the inner diameter of the sleeve element of the packaging and the outer diameter of the container element.

[0132] The innovative packaging according to the present invention provides a so-called "shelf life after opening" capability, meaning that after the packaging is first opened for use, in a closed configuration, it maintains a high level of barrier that extends the shelf life of the contents. This shelf life after opening is made possible by the fact that the movement of moisture and oxygen is minimal when the upper sleeve element completely closes the container element. Even in such a closed position, the packaging has a barrier of 1 cm when measured at 23°C and 50% relative humidity (RH). 3 / m 2 Less than 0.5 cm per day, preferably 0.5 cm 3 / m 2 Oxygen permeability (OTR) values ​​of less than / day, and 1 g / m³ when measured at 23°C and RH 85%. 2 Less than 0.5 g / m² per day, preferably 0.5 g / m² 2A water vapor transmission rate (WVTR) of less than 1 / day is maintained. This is due to the fact that the functional play (i.e., space) between the inner surface of the sleeve element and the outer surface of the container element is sufficiently small, and at the same time, the overlap between the sleeve element and the container element is sufficiently large, so that movement between the two is possible by the application of sliding force, while the movement of moisture and gases is largely prevented.

[0133] The packaging according to the present invention may, advantageously, be provided with holes / through-holes in the cardboard structure as “distributors” or “dose dispensers,” that is, mechanisms that enable accurate and user-friendly dispensing of contents, allowing the user to dispense a specific amount of product from the packaging for typically accurate and convenient use.

[0134] This packaging is made from sustainable materials, consisting of cardboard packaging for tubes made from environmentally friendly / biodegradable / recyclable and / or compostable materials, which have built-in barrier properties to ensure a long shelf life and product freshness without significantly affecting sensory characteristics.

[0135] This packaging features customizable characteristics, particularly in terms of size, shape, or color, which can be customized to suit different product types and customer needs, including cardboard tube packaging.

[0136] This packaging possesses exceptionally high barrier properties against the movement of gases and moisture through its walls. The developed packaging material offers high barrier functional properties that improve food protection and usability, including oxygen permeability (OTR), moisture resistance (WVTR), and odor blocking properties.

[0137] While optional, preferably the packaging material is UV resistant or light-blocking, and is therefore particularly useful for packaging certain food categories that are susceptible to UV light.

[0138] This tube packaging uses cardboard material that is flexible enough to be folded or crushed, while still being able to withstand the mechanical stress of stacking forces and top loads (which the packaging experiences when stacked for transport and storage), thus taking up less space when discarded after use.

[0139] The packaging according to the present invention is a shock-absorbing / cushioning system in which the mechanical elasticity of the existing tube material and the headspace integrated into the packaging cavity form an air pocket feature, protecting products susceptible to mechanical shock during transport or handling.

[0140] The simple shape of this packaging allows for a stackable design that minimizes product movement and optimizes transportation.

[0141] The fact that cardboard material with a very high cellulose content is used provides a sound-dampening effect, reducing noise during transport, as well as during opening, closing, and resealing. In this respect, this packaging is very user-friendly to use.

[0142] The preferred shape and diameter of the tube are selected to adapt to the human hand for an ergonomically superior and easy-to-grip design.
