Description

[0001] PLASTIC FREE FIBER-BASED CAPSULES ARTICLE

[0002] CROSS-REFERENCE TO RELATED APPLICATION

[0003]

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 655,890, filed June 4, 2024, which is incorporated herein by reference.

[0004] TECHNICAL FIELD

[0005]

[0002] This disclosure is related an improved and more sustainable capsule for use in topping a bottle. More particularly, this disclosure is related to a capsule comprising a fiber-based component and aluminum-based component that provides an improvement to the overall environmental impact when compared to traditional capsules.

[0006] BACKGROUND

[0007]

[0003] It has become increasingly desirable to design packaging structures that are more sustainable. Increased sustainability may be in the form of using raw materials that are renewably resourced, such as paper or other fiberbased materials. Alternately, increased sustainability may focus on other solutions through recycling and the removal of plastics, particularly thermoplastics, from existing structures.

[0008]

[0004] One area that requires a more sustainable solution is the capsules or caps market, as it is generally referred. A capsule, or a cap, is a metallic and / or plastic wrapping that is placed over the neck of a bottle to provide an initial protective layer around the bottle mouth and the installed cork or stopper. The capsule, in addition to the protective features, may also be ornamented, embossed, or labeled to identify the bottle or container when it is stored upon its side in a horizontal position with the primary label obstructed from view. A traditional capsule is generally comprised of an internal plastic layer positioned between a pair of external layers of aluminum. Recently, several countries have opted to address sustainability through the imposition of a tax on items that include plastic components, and specifically single use plastic items, such as capsules. Therefore, there is a need within the art of capsules for additional solutions to provide increased sustainability though capsules that are free of plastics (according to European Single-Use plastics directive), capable of being recycled in an aluminum recycling stream, and generally providing a reduction in the carbon footprint associated with manufacturing and distribution.

[0009] SUMMARY

[0010]

[0005] The developments described herein provide a sustainable capsule for a bottle top that is free of plastics to allow for a more sustainable option when compared to a traditional capsule that may include plastics or other thermoplastic-based materials. The sustainable capsule according to the present disclosure is generally constructed from a multilayer laminate comprising an aluminum layer positioned on an exterior surface of the sustainable capsule that is adhesively secured to a paper layer positioned on an interior surface of the sustainable capsule. In a preferred embodiment, the laminate maintains at least fifty percent (50%) of the aluminum layer by total multilayer laminate weight. Maintaining the aluminum layer at or near a target of at least 50% by weight ensures that the sustainable capsule can be included in an aluminum or glass bottle-based recycling stream. Alternately, the laminate may have an amount that is less than 50%, or slightly less than 50% by weight, while still maintaining enough aluminum to be detected as aluminum-based for recycling purposes.

[0011]

[0006] The aluminum layer is provided from a soft tempered aluminum having a thickness within a range from about 9 pm to 60pm. The paper layer is provided in a grammage within a range of about 25 grams per square meter (gsm) to about 85 gsm and is preferably comprised of a paper, a coated bleached paper, a kraft paper, a calendared paper, a super calendared paper, or other paper type. To ensure adequate crimping and folding during formation of the multilayer laminate into a capsule, the paper layer must be carefully selected with certain tensile properties, including elongation, to allow for a proper fit and assembly around the bottle, as this paper layer is generally considered the stiffer material having a larger impact on the overall folding and crimping characteristics of the sustainable capsule. The adhesive layer is generally provided in a grammage within a range of about 0.5 gsm to 10 gsm dry adhesive weight and is selected from the group comprising solvent-based and water-based adhesives.

[0027]

[0024] As used herein, the terms “preferred” and “preferably” refer to embodiments of the invention that may afford certain benefits, under certain circumstances. However, other embodiments may also be preferred, under the same or other circumstances.

[0028]

[0025] Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful and is not intended to exclude other embodiments from the scope of the invention.

[0029]

[0026] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element without departing from the teachings of the disclosure.

[0030]

[0027] The term "layer", as used herein, refers to a building block of films and / or laminates. A layer is a structure of a single material type or a homogeneous blend of materials. A layer may be a single polymer, a blend of materials within a single polymer type or a blend of various polymers. A layer may contain metallic materials and may have additives. Layers may be continuous with the film or may be discontinuous or patterned. Both layers and films have a relatively insignificant thickness (z-direction) as compared to their respective length and width (x-y direction). A layer may be a paper, and a paper may be a film.

[0031]

[0028] As used herein, a “laminate” is a film and / or filmic structure that may be built from an unlimited number of films and / or layers, the films and / or layers being bonded together by any known process such as, but not limited to, coextrusion, coating or laminating, to form a composite article, such as a capsule and / or cap.

[0032]

[0029] As used herein, the term “adjacent” means that the items, such as layers of a film, are near each other, with or without intervening material, such as adhesive. As used herein, the term “directly adjacent” or “in direct contact with” means that the items are in contact with each other, without intervening material.

[0033]

[0030] As used herein the term “paper” and / or “paper component" may be any type of paper that can be processed in a paper recycling (repulpability) process. As used herein, the term “paper” and / or "paper component" may be described with respect to an amount of cellulose fibers in the paper and / or paper component. For example, the paper and / or component comprises or may consist essentially of cellulose fibers. As used in this context, "consisting essentially of' means that the total composition of the paper component includes greater than or equal to 95%, greater than or equal to 98%, greater than or equal to 99%, greater than or equal to 99.9% or 100% cellulose fibers. In some cases, the paper and / or paper component may contain up to 20% mineral filler by weight and correspondingly an amount greater than or equal to 80% cellulose fibers.

[0034]

[0031] As used herein, the terms “fiber” and / or “fiber-based” may include, but not be limited to, cellulose and / or cellulose-based fibers including virgin cellulose-based fibers, recycled fibers including materials like paper fibers and craft papers, textiles, non-wovens, wood-based fibers, cotton, linen, hemp, sugar cane or sorghum commonly known as bagasse fibers, or grains. These fibers may be untreated and / or treated to provide enhancements or improvements to their inherent properties.

[0035]

[0032] As used herein, the term “basis weight” is used to refer to the amount of material by weight that is present in a predetermined area of a film, a layer, or a component, such as, but not limited to a paper. Typically, the area defined is a square meter, but any area can be used. The area is defined in the length-width (i.e. , x-y direction) of the film or layer. A material of a given thickness (z-direction) and density, has a specific weight when covering a defined area (i.e., a square meter). Basis weight is a commonly used measurement of weight for paper because the density of paper can vary widely. Stated differently, measuring paper by thickness in the z-direction can be difficult. Materials that are applied in discontinuous layers, such as a patterned material, can also be defined by basis weight. In the case of patterns, the basis weight refers to the amount of material by weight that is present when covering a defined area. The use of basis weight to measure weight of materials such as paper and patterned materials is common in the film converting industry.

[0036]

[0033] There is a need for a more sustainable capsule that is generally comprised of materials that are free from plastics, such as thermoplastics. By being free of plastics, this sustainable capsule is capable of being recycled within a traditional aluminum recycling stream. Accordingly, to comply with existing and proposed regulations, it is likely that the minimum content of aluminum within the sustainable capsule should be at least 50% by weight of the total capsule weight to achieve this recyclability characteristic. The sustainable capsule having the materials and properties of the present disclosure provides a more sustainable solution when compared to traditional capsules. Still further, the sustainable capsule according to the present disclosure limits curling, allows for printing and / or embossing, and complies with the European Directive 2019 / 904 related to single-use plastics.

[0037]

[0034] Referring now to FIGS. 1 - 4, a finished sustainable capsule 10 is shown along with a cross-section of a multilayer laminate 100 used to make the sustainable capsule 10. The sustainable capsule 10 is generally comprised of the multilayer laminate 100 that is folded to form the sustainable capsule 10 that is later crimped around a bottle during finished assembly. The sustainable capsule 10 has an exterior surface 11 generally aligned with an exterior of the capsule 10 and an interior surface 12 generally aligned with an interior of the capsule 10 and facing the bottle exterior. Accordingly, the capsule 10 interior surface 12 is in contact with the bottle at a position directly adjacent and not visible by a consumer and the exterior surface 11 is at a position that is visible by the consumer. Often, an upper and / or top of the capsule 10 exterior surface 11 includes a disc 13 that is adhered to the capsule for a finished and more adorned look.

[0038]

[0035] The multilayer laminate 100 includes a first layer being an aluminum layer 101, a second layer being a paper layer 102, and a third layer being an adhesive layer 103 positioned between the aluminum layer 101 and the paper layer 102. To ensure adequate recyclability and / or sustainability the composition and material choices for these layers must be carefully selected to maintain the sustainable features of the capsule 10. Most particularly, to generally maintain recyclability within traditional recycling streams associated with bottles, the aluminum layer 101 should likely comprise at least 50% of the weight of the total weight of the multilayer laminate 100. The aluminum layer

[0039] 101 is positioned as the capsule 10 exterior surface 11 and the paper layer

[0040] 102 is positioned as the capsule 10 interior surface 12, with each of the aluminum layer 101 and the paper layer 102 being outer layers of the multilayer laminate 100.

[0041]

[0036] In preferred embodiments of the present disclosure, the aluminum layer 101 is comprised of a soft tempered aluminum having a thickness within a range of about from 9 pm to about 60 pm. This tempering and thickness has shown good results and reduces the curling phenomenon associated with the capsule 10. In a preferred selection of materials for the aluminum layer 101, aluminum alloys of 8079 and 1200 types have been most useful, although other similar alloys and types may be applicable. The selection of the aluminum layer 101 as the exterior surface 11 of the capsule 10 enables for ease of converting as it behaves similar to more traditional and non- sustainable structures in use and converting processes. Additionally, the aluminum layer 101 is selected to allow for good printing, performance on existing machines, and good resistance to humidity.

[0042]

[0037] In preferred embodiments of the present disclosure, the paper layer 102 is provided in a grammage within a range of about 25 gsm to about 85 gsm. The choice of materials for this paper layer 102 is critical as different types of paper and thicknesses influences the results of crimping the capsule 10 onto a bottle during finished bottle assembly. As paper is generally considered to have more stiffness than aluminum when used in the sustainable capsule 10 structure, it needs to be carefully selected.

[0043]

[0038] Based upon experimentation, the tensile strength and elongation of a given paper in both the machine direction and the cross direction tends to provide guidelines for workability and / or machinability of a given multilayer laminate 100 for use in the sustainable capsule 10. Testing and experimentation has determined that paper materials having a machine direction tensile strength within a range of about 30 N / mm2to about 95 N / mm2and a cross direction tensile strength as measured within a range of about 30 N / mm2to about 80 N / mm2according to the European Standard for testing aluminum and aluminum alloys according to NF EN 546-2, tend to perform best, wherein pleated folds are maintained.

[0044]

[0039] In addition to strength, the extensibility or tensile stretch of the paper for the paper layer 102 is also relevant. Based upon experimentation and testing it was determined that paper materials having a machine direction tensile stretch within a range of about 2% to about 12% and a cross direction tensile stretch within a range of about 4% to about 14%, according to NF EN 546-2, tend to perform best.

[0045]

[0040] As the paper layer 102 is the interior surface of the capsule 10 and the layer in contact with the bottle and an adjacent capsule when stacked, the paper for the paper layer 102 should have a coefficient of friction that both allows for this stacking of prepared sustainable capsules 10 and placement onto a bottle neck. Accordingly, this coefficient of friction is necessary to both provide for slippage between capsules during assembly (paper interior side and aluminum exterior side) and during placement (paper interior side against glass bottle side). Based upon testing and experimentation, it was determined that the coefficient of friction of the interior surface 12 along a glass plate as measured is within a range of about 0.30 to 0.65, according to International Organization for Standardization Test ISO 15359:1999.

[0046]

[0041] In preferred embodiments of the present disclosure, the paper for the paper layer 102 is preferably selected from the group of paper types comprising coated bleached kraft papers, calendared papers, and super calendared papers within the grammage ranges enumerated above and available from various manufacturers.

[0042] The adhesive layer 103 is positioned between the paper layer 102 and aluminum layer 101 to complete the lamination of the paper and aluminum structures. The adhesive layer 103 is provided from an adhesive of the waterbased or solvent-based type and provided with a dry weight grammage within a range of about 0.5 gsm to 5 gsm. In a preferred embodiment, the adhesive is selected from a casein-based adhesive, if of the water-based type or a polyurethane-based adhesive, if of the solvent-based type. Using an adhesive for the adhesive layer 103 of the multilayer laminate 100, as opposed to a common and existing plastic film structure, enables for the overall reduction of various layers of the laminate 100 to achieve the minimum of 50% as a target of aluminum in the laminate 100 and enables the laminate 100 to be considered “plastic free.”

[0047]

[0043] Referring now to FIGS. 3-4, in an alternate embodiment of the multilayer laminate 100, may include an optional lacquer 104, 105 layer. This optional lacquer 104, 105 is generally described as a coating and may be present on either one of or both of an outer surface of the aluminum layer 101 aligned with the exterior surface 11 when used as a capsule and an inner surface of the paper layer 102 aligned with the interior surface 12 when used as a capsule. The lacquer 104, 105 is generally considered a coating that can impart additional properties, such as, but not limited to, a matte or brightened / shiny appearance, optimize a coefficient of friction to improve sliding, or improve printability. Preferably, the lacquer 104, 105 is provided in a grammage within a range of about 0.5 gsm to about 2 gsm.

[0044] An exemplary multilayer laminate ‘A’ having a layered structure of multilayer laminate 100 was constructed on pilot equipment and converted via traditional packaging machines to form a capsule 10. The exemplary laminate comprised an aluminum layer of soft tempered aluminum in a thickness of 20pm as an exterior surface of the capsule. The aluminum layer is adhesively laminated with a water-based adhesive having a dry weight grammage of 1 gsm to a paper layer. The paper layer is a coated and bleached kraft paper in a thickness of 40 gsm. The aluminum layer exterior is coated with a lacquer in an amount of .9 gsm. The exemplary multilayer laminate ‘A’ was tested for both tensile strength and elongation. The laminate ‘A’ has a measured strength of 74 N / mm2in the machine direction and 59.1 N / mm2in the cross direction. The laminate ‘A’ has a measured elongation of 2.7% in the machine direction and 5.9% in the cross direction. The measured coefficient of friction of laminate ‘A’ is .57.
