Description

Technical Field

[0001] The present invention relates to a container made of a foldable laminate material for containing articles such as foods and beverages, and particularly to a wide-mouth bottle made of a foldable laminate material for containing articles.

Background Art

[0002] There are many advantages to foldable laminate packaging such as Tetra Pak (registered trademark) cartons. For example, the laminate can be configured to form a sterile container that can keep food fresh for a longer time. Since the laminate is relatively lightweight, transportation costs can be minimized. Through various printing processes, displays can be printed on the laminate material.

[0003] Conventional Tetra Pak (registered trademark) cartons are formed from a single laminate sheet with two opposing edges connected. Subsequently, the adjacent edges of the laminate container are sealed at both the upper and lower parts of the container. Thereby, a seal is arranged at the upper part of the container. The excess material at the upper part is usually folded towards the side surface adjacent to the upper surface, and the excess material at the lower part is folded towards the bottom surface of the container. In some cases, a flat bottom seal may also be used.

[0004] Normally, a small opening is provided at a position offset from the upper seal on the upper surface. This small opening is ideal for carefully pouring liquids such as milk and juice stored in the container.

[0005] However, this type of container is not suitable for storing solids, viscous liquids, or powders because the contents cannot be easily removed from the carton through the opening. For this reason, these items are still sold in wide-mouthed glass bottles or plastic containers that have an opening at the top. Wide-mouthed glass bottles and plastic containers are usually shipped empty from the manufacturer and then filled. Due to the large capacity per container, transportation costs are high, resulting in a large carbon footprint that is not environmentally sustainable. Wide-mouthed glass bottles, in particular, are expensive to manufacture and heavy, further exacerbating transportation costs and environmental impact.

[0006] In the case of Tetra Pak®, the carton material consists of six distinct layers. The first layer is a waterproof polyethylene layer. The second layer is a second polyethylene layer that functions as an adhesive layer, used to bond the first layer to the third layer of aluminum foil, which preserves the freshness of the contents. The fourth layer is a third polyethylene layer that functions as an adhesive layer to bond the third layer to the fifth layer of cardboard, which can display the contents of the product and brand information. The sixth layer is a fourth polyethylene layer that waterproofs the material. Other manufacturers may offer different cartons or laminates.

[0007] While the laminated structures offered by various manufacturers are generally effective in extending the shelf life of food in corresponding laminated containers, they tend to require special disposal procedures because separating individual layers of the laminate is difficult during the recycling process. Furthermore, some recycling collection services in the UK do not accept various laminated materials as paper recycling; instead, consumers must take containers made of these materials to recycling centers that accept laminated containers. With a lack of convenient means of recycling without leaving the home (i.e., in-home recycling collection), some people may dispose of laminated materials as general waste. Globally, approximately 1.2 million tons of paper cartons were recycled in 2022. Therefore, even if a relatively small number of cartons are discarded without being recycled, the amount is enormous.

[0008] The present invention aims to mitigate or substantially eliminate the aforementioned problems. [Overview of the project]

[0009] According to a first aspect of the present invention, a container for articles (or a wide-mouthed bottle made of laminated material) is provided. This container has a container body formed by folding laminated material, and the container body is The first end wall is formed by laminated material, The second end wall is formed by laminated material, It comprises at least one side wall formed by a laminated material connecting a first end wall and a second end wall, The first end wall, the second end wall, and at least one side wall define an internal space for accommodating articles. An opening is provided substantially in the center through the laminate of at least one side wall, the side wall having the opening has an outer edge that defines the side wall area, the opening occupies at least 40% of the side wall area, the opening extends at least about 71% of a first distance across the side wall having the opening in a perpendicular direction from the first fold of the first end wall to the second fold of the second end wall, and the opening extends at least about 71% of a second distance across the side wall having the opening perpendicular to the first distance. The opening has opening edges at a first point, a second point, a third point, and a fourth point on the opening edge, each of which is closer to the outer edge of the side wall having the opening than to the center of the opening; the first and second points face each other across the opening; the third and fourth points face each other across the opening; and the first, second, third, and fourth points are arranged at equal intervals around the opening edges. The container body includes at least one seal for sealing the folded laminate in the shape of the folded container body, the at least one seal being a) located on a first or second end wall (therefore on a container wall different from the opening), or b) located on at least one side wall and offset from the opening.

[0010] Any features may be described in the dependent claims.

[0011] The container according to the present invention provides a lightweight and cost-effective alternative to glass bottles, plastic bottles, wide-mouthed bottles, and other containers. This container has the advantage of forming various walls (including the side walls with openings and the bottom surface of the container) by folding and shaping a single laminated material. Unlike glass and some plastic containers, it has the additional advantage of not shattering upon impact.

[0012] The opening of the present invention is relatively wide, allowing articles to pass through the opening easily and / or quickly.

[0013] Multiple points, evenly spaced along the edge of the opening, are each located closer to the periphery of the side wall than to the center of the opening, resulting in the opening being wider in both length and width relative to the length and width of the side wall. In a preferred embodiment, all points on the edge of the opening (whether for a circular opening or other shaped opening) are located closer to the outer edge of the side wall having the opening than to the center of the opening. For example, in a central circular opening occupying at least 40% of the side wall area having the opening, the entire edge of the opening is located closer to the outer edge of the side wall than to the center of the opening.

[0014] The central region (or center) of the opening may be located in the center of the side wall. A configuration in which the central region (or center) of the opening is located in the center of the side wall, with the seal offset or located in an adjacent end wall, can provide greater space for accommodating large or wide openings. This allows for maximizing the size of the opening relative to the size of the container. This is particularly useful in the pre-molded bottle and wide-mouth bottle packaging industries, and the present invention enables a significant shift towards more useful and sustainable packaging.

[0015] In another aspect of the present invention, at least one seal may be positioned offset from the opening on at least one side wall, rather than being positioned on a wall different from the opening.

[0016] The container may have first and second central planes that are perpendicular to each other. The center of the opening may be located on the side wall at the intersection of the first and second central planes.

[0017] In other words, the container has two orthogonal planes, one parallel to the end wall and the other perpendicular to that end wall, and the center of the opening may be located near where these planes intersect. The central plane can also be a longitudinal plane passing through the centers of the opposing side walls.

[0018] In a preferred embodiment, the opening is located substantially in the center of the side wall having the opening. However, it will be understood that in other embodiments, the opening may be offset from the center of the side wall having the opening. For example, the opening may be located near the center of one end of the side wall having the opening, near a corner of the side wall having the opening, or at any position on the side wall having the opening that allows the entire opening to be contained within the perimeter of the side wall having the opening.

[0019] The term "folded" may be interpreted as meaning that the container is formed from a single piece of laminate having one or more folds. The pieces of laminate may be supplied as individual pieces or cut from a continuous piece of laminate. The container body may have any appropriate number of folds. A given fold may be placed between two adjacent walls of the container body, so that those walls are joined at a distinct angle.

[0020] The container may be treated as a carton or a laminated wide-mouth bottle, in particular as a resealable carton or laminated wide-mouth bottle.

[0021] The container can be used for one or more of the following purposes: retort, sterile, room temperature storage, and refrigerated storage. In other words, it can be used for food storage under various conditions. It will be understood that the container is not limited to food storage but can also be used for various other purposes, as will be discussed later.

[0022] The first end wall may be considered to face the second end wall.

[0023] The opening has a diameter that extends substantially over most of the width of its base side wall.

[0024] There may be no seal in the laminate provided on or across the side wall having the opening. That is, the joint between separate parts of the laminate may not be provided on the side wall having the opening.

[0025] A flat wall can be provided at the bottom of the internal space. This flat wall faces the opening or the side wall having the opening. In other words, the bottom of the container is substantially flat (it may be either one or both of the inner surface of the bottom or the surface facing the internal space and the outer surface of the bottom).

[0026] The flat wall and the opening may be arranged in respective planes that are substantially parallel to each other.

[0027] The inner surface of the flat bottom may be substantially flat throughout its entire area. The inner surface of the flat bottom may have no protrusions or recesses. The flat wall may have no recesses or depressions.

[0028] As a result, there are fewer processing changes in the folding / molding process of the container body using the laminate, enabling simplification of container manufacturing.

[0029] The flat wall can include a seal. This helps, for example, to reduce the risk of articles leaking from the laminate through the bottom.

[0030] The opening has a sufficient width for an instrument such as a spoon, which is narrower than the opening, to be inserted, and one or more articles can be taken out from the internal space by manually inserting and removing the instrument through the opening.

[0031] The opening can extend over a range of up to approximately 90% or 95% in a direction perpendicular to the distance from the first end wall to the second end wall of the opening side wall.

[0032] The opening can be considered a wide opening. The opening is designed to accept or allow the insertion of an utensil such as a spoon for removing an item. That is, the opening is a wide opening that accepts an utensil such as a spoon that is narrower than the opening itself, and the item can be removed from the internal space by manually inserting and withdrawing the utensil through the opening.

[0033] This wide opening may include a neck or neck portion for receiving a closure. The neck is glued or attached to the laminate. The neck extends out of the internal space by a neck height. The neck height is, for example, up to about 3 cm or 4 cm. The neck height is about 1 cm or 2 cm.

[0034] The neck portion may have a neck width (neck opening width) that corresponds to at least approximately 71% of the first distance in the orthogonal direction from the first fold of the first end wall to the second fold of the second end wall in the side wall having an opening (hereinafter also referred to as the opening side wall). In other words, the neck portion is approximately the same width as the opening. The neck width is at least three times, or at least four times, the neck height.

[0035] The neck portion may define a disc-shaped or cylindrical opening whose diameter is greater than its height.

[0036] The neck portion may include at least one flange or lip. At least one flange may be bonded to the laminate at the corner of the sidewall facing the interior space.

[0037] This maximizes the area of ​​the opening's side wall while allowing the neck portion to be properly fixed to the laminated material at various corners of the side wall.

[0038] The seal between at least one flange and the side wall may be a circumferential seal around the opening.

[0039] The neck portion may be glued to the inside or outside of the container. If glued to the inside, this should be done before folding the laminate to form the container.

[0040] The width of the opening is at least 3 cm, or at least 4 cm, or at least 5 cm. In some embodiments, an opening with a diameter of any integer or half-integer value in the range of 3 cm to 15 cm can be provided, for example, with a width of 8.5 cm.

[0041] The opening may be, for example, at least 3 cm in both length and width (or diameter). In other examples, the opening may be about 4 cm or 5 cm in both length and width (or diameter). In yet another example, the opening may be about 6 cm, 8 cm, or 10 cm in both length and width (or diameter).

[0042] An opening side wall may have an outer edge that defines the side wall area (or enclosed area). That is, a fold at the boundary of the side wall may define the area of ​​the side wall.

[0043] The opening covers an area occupying at least 40% (or more) of the side wall area. Therefore, in the case of a circular opening in a square or rectangular side wall, the diameter of the opening will be at least 71% of the length and / or width of the opening side wall.

[0044] In some embodiments, the area of ​​the opening may be at least 45% or 50% (or more) of the side wall area. In other embodiments, the area of ​​the opening may be at least 55% or 60% (or more) of the side wall area. The area of ​​the opening may be up to approximately 75% of the side wall area, that is, the area enclosed by the periphery of the side wall.

[0045] For a circular opening that covers at least 50% of the side wall area of ​​a square or rectangle, the diameter of the opening should be at least 80% of the length and / or width of the opening's side wall.

[0046] For a circular opening that covers at least 60% of the side wall area of ​​a square or rectangle, the ratio of the opening diameter to the length and / or width of the opening's side wall is approximately 87% or more.

[0047] The above percentage values ​​for openings may vary depending on the shape of the opening (circular or other shapes) and the shape of the side wall area (rectangular or other shapes), but as a general principle, openings occupy a large proportion in both the length and width directions of the opening side wall.

[0048] The opening has an area that covers at least 40%, at least 50%, or at least 60% of the area defined by the periphery of the opening side wall, and may have a diameter of at least about 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, or 10 cm. The diameter of the opening can be up to a maximum of about 15 cm, 20 cm, or 25 cm.

[0049] The opening should preferably be as large as possible within the area of ​​the side wall, but not to the extent that it impairs the overall structure of the side wall.

[0050] In other words, the opening or neck can approach an inscribed opening (e.g., an inscribed circle) within the opening's sidewall, but the periphery of the opening is set slightly inward from the periphery of the sidewall to the extent necessary to maintain the structural integrity of the container body. For example, it may be set inward by a few millimeters to a maximum of approximately 1 or 2 cm (measured perpendicular to the periphery of the sidewall). When a neck or closure receiver is attached to the container, this setting allows the neck or closure receiver to connect properly to the laminate.

[0051] Laminated containers with wide openings can be used as an alternative to glass bottles or wide-mouthed glass bottles, for example. This allows for the realization of the advantages of laminated containers, such as reduced logistics, transportation, and storage costs for additional packaging.

[0052] The midpoint between the center of the first edge of the opening side wall and the center of the opposite edge of the opening side wall may be located within the opening.

[0053] The interior-space-facing surface of the opening sidewall may have an area smaller than the area of ​​the opening. The majority of the interior-space-facing surface area of ​​the opening sidewall may be located on or near the corners of the opening sidewall.

[0054] The area of ​​the interior-facing surface of the opening sidewall is up to approximately 60% of the total area defined by the outer edge of the opening sidewall. The area of ​​the interior-facing surface of the opening sidewall may be between approximately 22% and 50% of the total area enclosed by the outer edge of the opening sidewall. For example, approximately 25%, 30%, 35%, 40%, or 45% of the total area may consist of the sidewall area rather than the opening area.

[0055] The first and second opposing points on the periphery of the opening may be located closer to the periphery of the opening's side wall than their relative distance from each other. The third and fourth opposing points on the periphery of the opening may also be located closer to the periphery of the opening's side wall than their relative distance from each other. The first, second, third, and fourth points may be arranged at equal intervals along the edge of the opening.

[0056] For example, in the case of a circular opening, there may be two points offset by 90 degrees on the edge of the opening, and one or both of these points may be located closer to the periphery of the side wall than to the center of the opening.

[0057] The average distance between the periphery of the opening side wall and the opening edge (e.g., the arithmetic mean distance) may be smaller than the average distance between the opening edge and the center of the opening (e.g., the arithmetic mean distance).

[0058] The first distance between the center of the opening sidewall and the center of the opening may be less than the second distance between the center of the opening and a point on the periphery of the opening sidewall. In this case, the point, the center of the opening, and the center of the opening sidewall are collinear.

[0059] The opening may be circular.

[0060] The opening may be a single opening located in the side wall of the opening; that is, it may be the only opening from which an item can be removed from the container.

[0061] The laminated material may have barrier properties against odor, oxygen, ultraviolet light, and moisture.

[0062] The laminate may include any combination of the following: one or more polymer or plastic layers, such as polyethylene; one or more metal layers, such as an aluminum layer; and one or more cardboard layers. The laminate may be, for example, a conventional Tetra Pak® laminate. Alternatively, the laminate may be a material according to a fifth aspect of the present invention.

[0063] At least one seal is formed or provided at a location where different parts or edges of the laminate are joined to each other (e.g., by heat sealing or adhesive bonding) to form the container body. The at least one seal may include overlapping portions of the laminate.

[0064] A first seal is provided on or on the first end wall to seal the folded laminate at the first end wall. A second seal is provided on or on the second end wall to seal the folded laminate at the second end wall.

[0065] The seal may be placed on the container surface adjacent to and / or opposite the opening surface.

[0066] One or more folding tabs (or flaps) may be provided on or sealed to the first end wall. However, it will be understood that a flat seal may also be used.

[0067] One or more folding tabs (or flaps) may be provided on or sealed to the second end wall. However, it will also be understood that a flat seal may be used.

[0068] Each tab or flap may be substantially triangular in shape. However, it will also be understood that tabs or flaps of different shapes may be provided.

[0069] At least one foldable tab portion is provided on both the first and second end walls, or sealed to them.

[0070] The folding tab portion may be formed from laminated material. The laminated material forming the folding tab portion can be considered as the surplus portion of laminated material that was not used to form the walls that define the internal space of the container body. The folding tab portion may be formed by folding a substantially rectangular piece of laminated material into the container body.

[0071] At least one edge seal may be substantially formed along the overlapping edges of the laminate. The edge seal may extend perpendicular to the first and second seals. The edge seal may be located on at least one sidewall. The edge seal may be located substantially in the center of the sidewall. The edge seal may be located offset from the center of the sidewall.

[0072] A first seal may be provided on the first end wall, and a second seal on the seal end wall. The seals may be positioned opposite each other across the opening side wall. If one or more additional side walls are provided, seals may not be provided on the additional side walls. That is, one or more additional side walls may each be a "continuous" wall, or a wall not interrupted by a seal formed by bonding or fixing two different parts of a laminate. However, the wall itself provides a barrier to resist or prevent leakage of articles from the container.

[0073] It can have at least four side walls. The container is substantially rectangular or prismatic in shape.

[0074] The container may be constructed using a net-like laminate, that is, a shape that folds into the desired container body. The net may be a single, foldable net that provides all the side and end walls of the container. The net may have two or more pairs of edges, each having a first edge substantially parallel to the other and a second edge facing it. For example, the container may be constructed using a net that is substantially square or rectangular.

[0075] The opening side wall is positioned between the first end wall and the second end wall, and they can be connected. That is, the first end wall and the second end wall are positioned on opposite sides of the opening side wall. The opening side wall, as part of the net, is positioned between their end walls, and they can be connected.

[0076] The opening side wall may be connected to the first end wall by a fold and / or to the second end wall by a fold.

[0077] The container itself may be a substantially rectangular prism with a square base, or a regular square prism. The square base of the container may face the open side wall.

[0078] The opening side wall may have a square or rectangular perimeter.

[0079] The container body has a height-to-width ratio relative to the opening side wall, and this height-to-width ratio is substantially within the range of 2:1 to 1:2.

[0080] The height of a container may be at least half its width. The height of a container may be up to twice its width. The height of a container may be measured along an axis parallel to the central axis of the opening. The width of a container may be measured along an axis perpendicular to the central axis of the opening.

[0081] This makes it possible to create containers with a relatively short, squat shape. In other words, the container has a low center of gravity, which reduces the risk of it accidentally tipping over when subjected to impact.

[0082] The minimum internal volume of the container is approximately 25 ml. The maximum internal volume of the container is approximately 5000 ml.

[0083] The unit is cm instead of ml. 3 However, this is also acceptable. The internal space volume is an integer value in the range of 25 ml to 5000 ml (e.g., 50 ml, 75 ml, 100 ml, 125 ml, 150 ml, 200 ml, 250 ml, 300 ml, 400 ml, 500 ml, 750 ml, 1000 ml, 1500 ml, 2000 ml, 2500 ml, 3000 ml, 3500 ml, 4000 ml, or 4500 ml). The range of the internal space volume may be set such that the lower and upper limits are independently selected from any of the values ​​described herein.

[0084] A container may be substantially empty in order to receive goods. A container can receive goods in a volume substantially equal to, or close to, the internal volume of the container (the remaining volume may be filled with a gas such as nitrogen).

[0085] The container may include multiple side walls of the laminate. That is, in addition to the side wall having an opening, one or more additional side walls may be provided. Each of the multiple side walls may be connected to each other by a first end wall and a second end wall. Each of the multiple side walls may be connected to different side walls on each side. The opening may be provided penetrating through one of the laminated side walls.

[0086] At least one side wall may be formed from a continuous, uninterrupted portion of the folded laminate. That is, the folded laminate may extend continuously on a single plane without interruption by at least one seal. The opening may be positioned through the continuous portion of the folded laminate of the side wall. The absence of a seal on that side wall can provide space to accommodate a larger opening, such as a wide-mouth opening.

[0087] In other words, the side of the container with an opening may lack a seal where two different parts of the laminate are sealed to each other.

[0088] If at least four side walls are provided, at least two or at least three side walls do not include a seal. One side wall may include a seal or an edge seal. The edge seal is formed along the longitudinal direction of the container.

[0089] The opening may be positioned through the planar portion of the folded laminate.

[0090] Labeling of the container contents / articles (such as food or tablets), including branding and images, is provided on the laminate by printing or other means. Labeling is provided on either one or both of the first and second end walls. Labeling is provided on one, part, or all of the side walls. Labeling may be provided on at least one fold-over tab portion.

[0091] A display on at least one folding tab may be aligned with a display on at least one corresponding end wall to form, for example, a continuous image, logo, or text. If a folding tab is positioned to cover a display on either the first or second end wall, the display on the folding tab may be substantially identical to the concealed or covered display on the first or second end wall.

[0092] By aligning the markings on the folding tabs with the markings on each end wall, the markings spanning the folding tabs and each end wall form a substantially continuous appearance. This results in a more aesthetically pleasing container.

[0093] The opening can be sealed with a metal foil lid or metal foil laminate. For example, the metal foil is aluminum. Metal foil lids are preferred for aseptic packaging applications. Metal foil lids can prevent the intrusion of one or more of moisture, light, oxygen, and bacteria.

[0094] The laminated lid seal can be made of foil-coated paper. By providing individual closures on the lid seal, it is possible to protect the seal before opening the internal space and to re-close the opening after the lid seal has broken.

[0095] The opening is re-closed or substantially re-sealable by a closure, cap, or lid. For example, a closure is a screw-on lid or a push-on lid. The closure or lid is suitable for sealing the opening to prevent articles from flowing out of the internal space and / or to prevent outside air from entering the internal space.

[0096] A closure, cap, or lid may include a top wall having a top wall area equal to or greater than that of the opening in order to cover the opening. The top wall may be a flat top wall. A closure, cap, or lid may include a peripheral rim on the wall. A closure, cap, or lid may have threads around the peripheral rim for engaging with corresponding threads provided on the container. The corresponding threads may be provided, for example, on a neck portion that is attached to the container body.

[0097] The closure or lid may include a brand or image corresponding to the articles inside the container. The brand or image may be provided on the top wall (preferably a flat surface).

[0098] The closure may be substantially above the opening. The closure may be located at the rim of the container. In other words, the closure may not substantially penetrate into the container. Placing the closure at the rim or outside the container ensures a substantially empty internal volume for receiving articles.

[0099] To dispense the contents, the closure or cap can be removed or detached from the container. For example, a screw-on lid can be removed.

[0100] The container may not include a pump dispenser. That is, the closure, lid, or other device that closes / seals the opening may not incorporate a pump dispenser. For example, pump dispensers are particularly unsuitable if the item is solid, powdery, or viscous.

[0101] Furthermore, it should be noted that the opening of the pump dispenser needs to be small in order to ensure a relatively large bonding area for the part of the pump dispenser that is bonded to the container. In addition to the small opening and large bonding area, the pump dispenser needs to be used with a relatively rigid container structure. Otherwise, the pressure applied to the pump dispenser during use may cause the container wall to deform excessively, potentially cracking and causing the contents to leak.

[0102] The closure device can be made of metal such as aluminum. The closure device can be made of plastic.

[0103] The closure and metal foil seal may both be provided as part of the container.

[0104] When using a screw-on lid, the neck portion or lid receiver may be fixed or sealed to the side wall into which the lid is screwed.

[0105] When using a push-in lid, the lid forms a substantial seal against the opening rim through the push-in connection. The push-in lid may protrude to some extent into the internal space.

[0106] The closure or lid can be designed to match the markings, colors, patterns, and color scheme of the container. This makes it easier to match the correct lid when multiple containers of similar sizes are opened simultaneously, and is also useful when using the same size closure for containers of different sizes. This helps prevent the mixing of items between containers.

[0107] The closure may be a childproof cap. A childproof cap is preferred if the container contains pharmaceuticals and / or nutritional supplements. The closure may be provided in addition to a metal foil lid. The closure may make the container substantially resealable even after the metal seal (if provided) is broken, for example, to extend the shelf life of the contents of the container.

[0108] Containers may be included or used to package articles such as rapidly changing consumer goods. Articles may include wet or dry goods. Articles may include solid or semi-solid articles (semi-solid articles may include at least some solid parts, be a fluid solid, or include some solid parts and some liquid parts). Articles may include liquids.

[0109] The container may contain or be suitable for receiving viscous liquid articles.

[0110] Containers may contain liquids or articles that cannot be easily poured and / or pumped. For example, articles may contain solid articles stored in / below a liquid (e.g., gherkins in pickling or brine).

[0111] The items may include one or more of the following: - Foods or beverages such as mayonnaise, peanut butter, chocolate spread, nuts, baby food, coffee beans or coffee granules / powder (including other granules / powder), pasta sauce, mustard, jam, thick cream, pickles, flour, salt, microwaveable foods, and confectionery. - Health and beauty products (or cosmetics) such as powdered milk, lotions, gels, creams, powders, and other solid substances. - Medications such as digestive aids (for digestive health), multiple capsules (or tablets / pills), oral medications, and ointments. - Nutritional supplements such as multiple vitamin tablets, supplements, and protein powders

[0112] The container can be used to package items such as pet food, oils and / or greases, and industrial powders.

[0113] Containers or laminates may be suitable for microwave irradiation to heat the contents inside (i.e., they may be microwave-safe containers). For example, if a container contains microwave-safe food or contents, the laminate and closure should be made of microwave-safe materials.

[0114] The container may be a chemical container for holding solid chemicals, such as laboratory chemicals. The internal space of the container (or the surface of the laminate facing the internal space) may be lined with an inert or passivating layer, such as a polymer layer or metal layer, such as polytetrafluoroethylene (PTFE) or platinum. It will be understood that other polymers and metals (or materials) may be used, insofar as they are suitable for use with the articles inside the internal space.

[0115] For example, the container is suitable for storing non-edible chemicals and household chemicals. Specifically, the container can contain any of the following: laundry powder detergent, laundry capsules, dishwasher capsules / tablets, and industrial chemicals. For example, it can provide soda crystals or other pipe clearers.

[0116] Therefore, this container offers a safer way to store household items compared to simple cardboard boxes that children can open relatively easily, while also providing a more environmentally friendly option than conventional glass or plastic packaging.

[0117] This container is preferably used for chemical articles that do not require specific protective packaging. For example, leak absorbents and horticultural fertilizers can be contained in this container.

[0118] A second aspect of the present invention provides a method for manufacturing a foldable laminate container. This method includes the following steps: i. The process involves folding a sheet of laminated material into a container body having a first end wall, a second end wall, and at least one side wall connecting the first and second end walls, wherein the internal space of the container body is defined by the first end wall, the second end wall, and at least one side wall, and an opening is provided through the laminate of at least one side wall, the opening extending at least about half the distance across the opening side wall in a direction perpendicular to the first end wall to the second end wall. ii. A process of sealing a laminated material into the shape of a container body such that the internal space is suitable for holding an article, and including at least one seal, the seal being a) positioned offset from the opening on at least one side wall, or b) positioned on a first end wall or a second end wall (not the opening side wall).

[0119] The advantages are the same as those discussed with respect to the first aspect of the present invention.

[0120] The process of folding a laminated sheet may involve folding one or more sections of the sheet into multiple folding tabs.

[0121] The laminated material can be pre-folded, or the method may include a step of folding or pre-folding the laminated material.

[0122] The opening is provided or formed in the laminate before the folding process.

[0123] The closure, or its neck portion, may be applied to the laminate before the folding process.

[0124] The laminated material can first be folded into a tubular structure, and then each part of the material can be folded into the end wall. By overlapping the materials and sealing along the overlapping portion, a longitudinal edge seal can be formed.

[0125] Sealing a container-shaped laminated material involves sealing the folded portion of the end wall to prevent spillage or leakage of the contents.

[0126] The sealing of the laminated material involves sealing a portion of the folded tab at the first end wall to the container body.

[0127] The sealing of the laminated material may involve sealing a portion of the folded tab to the container body at the second end wall opposite the first end wall.

[0128] In laminated materials, seals may not be provided on or across the opening sidewall.

[0129] In another aspect of this method, at least one seal may be positioned offset from the opening on at least one side wall, rather than on a wall different from the opening.

[0130] A third aspect of the present invention provides a container for articles. The container has a container body formed by folding a laminate, the container body comprising a first end wall of the laminate, a second end wall of the laminate, and at least one laminate side wall connecting the first end wall and the second end wall, the first end wall, the second end wall and at least one side wall defining an internal space for containing articles, an opening provided through the laminate of at least one side wall, the center of the opening positioned on a first central plane of the container and also on a second central plane of the container, the second central plane being perpendicular to the first central plane, and the container body includes at least one seal for sealing the folded laminate as a container body, the at least one seal being a) positioned on the first end wall or the second end wall, or b) positioned on at least one side wall offset from the opening.

[0131] Features presented in relation to the first aspect of the present invention, or combinations of independently selected features, may be provided in a third aspect of the present invention.

[0132] A fourth aspect of the present invention provides a method for manufacturing a foldable laminate container. This method may include the following steps: i. A step of folding a sheet of laminated material into a container body having a first end wall, a second end wall, and at least one side wall connecting the first and second end walls, wherein the internal space within the container body is defined by the first end wall, the second end wall, and at least one side wall, and an opening is provided through the laminated material of at least one side wall, the central part of the opening is positioned on a first central plane of the container body, and also on a second central plane of the container body perpendicular to the first central plane. ii. A process of sealing a laminated material into the shape of a container body, such that the internal space is suitable for holding an article, and includes at least one seal, the seal being a) positioned offset from the opening on at least one side wall, or b) positioned on a first end wall or a second end wall.

[0133] Features presented in relation to a second aspect of the present invention, or combinations of independently selected features, may be provided in a fourth aspect of the present invention.

[0134] According to a fifth aspect of the present invention, a laminate for aseptic packaging or retort packaging is provided. The laminate comprises a first layer, an adhesive layer, and a rigid second layer, wherein the first and second layers are formed from different materials, the first and second layers extend over substantially the same area, and the first and second layers are peelably bonded together. The first layer consists of a metal or metal alloy surrounding the internal space to prevent oxygen and / or light from passing through the laminate and entering the internal space. The second layer consists of a cellulose-based material or cardboard.

[0135] Any features may be described in the dependent claims.

[0136] One advantage is that this laminate is easier to recycle than currently available laminates. Separable layers can be separated to facilitate recycling. This can improve recycling compliance when recycling is chosen instead of disposing of the laminate (or its container) in a general waste container.

[0137] Laminated materials do not contain polyethylene or polyethylene-based adhesives (i.e., they do not contain polyethylene-based or polyethylene-derived adhesives). Laminated materials using polyethylene-based adhesives are difficult to recycle.

[0138] The laminated material can be supplied in the form of a carton, a wide-mouthed jar, or a bottle body, or it can be folded.

[0139] The bottle body may be a container described in the first, second, third, or fourth aspect of the present invention.

[0140] One or more markings may be provided on the outside of the laminate. A sleeve or sticker with one or more markings may be provided on top of the laminate.

[0141] The first layer may form a terminal layer. The metal or metal alloy includes one or more of the following: aluminum, stainless steel, copper, iron, brass, tin, silver, titanium, nickel, and bronze.

[0142] At least one of the first and second layers may include tabs to facilitate separation between the first and second layers.

[0143] The laminate may have a third layer containing glassine for forming a terminal glassine layer. The third layer may be peelably bonded to at least one of the first and second layers by means of, for example, a second adhesive layer or other means.

[0144] The laminate is substantially composed of only a metal / alloy layer, an adhesive layer, and a cellulose layer, and may include additional adhesive layers and glassine layers as needed.

[0145] In a preferred embodiment, a portion of the first layer may provide (or form) at least a portion of a flap located outside the periphery of the second layer.

[0146] In other words, the majority of the first layer is located within the periphery of the second layer. However, a small amount of the first layer may extend beyond the side edge of the second layer. This provides an area for the first layer to adhere to itself when the laminate is folded into a container.

[0147] The profile (outer shape) of the first layer may not match the profile of the second layer. The laminate may have a first edge. The laminate may have a second edge opposite the first edge. The first and second layers may each have a first lateral extension at the first edge and a second lateral extension at the second edge. The lateral extension of the first layer at the first edge may be larger than the extent of the lateral extension of the second layer at the first edge. The lateral extension of the second layer at the second edge may be larger than the extent of the lateral extension of the first layer at the second edge.

[0148] When the container is folded, the spread of the different lateral extensions of the layers allows a portion of one side of the first layer to adhere to the opposite side of the first layer. A portion of one side of the second layer can adhere to the opposite side of the second layer.

[0149] The area of ​​the first face of each layer may be bonded to the area of ​​the second face of that layer.

[0150] The laminated material may or may not have openings. That is, the laminated material may be used to form a container according to the first embodiment, for example, or to form a different type of container.

[0151] According to another aspect of the present invention, a container for articles is provided. The container is formed from laminated material and folds as a container body, having a first end wall of laminated material, a second end wall of laminated material, and at least one side wall of laminated material connected to the first end wall at the first fold and connected to the second end wall at the second fold, the at least one side wall connected to the first end wall at the first fold and connected to the second end wall at the second fold, connecting the first end wall and the second end wall to each other, the first end wall, the second end wall and at least one side wall define an internal space for accommodating articles, and an opening is provided through the laminated material of at least one side wall, the opening extending in a direction perpendicular to the first end wall to the second end wall, over at least about half the width of the opening side wall, the container body includes at least one seal for sealing the folded laminated material as a container body, the at least one seal is a) on either the first end wall or the second end wall, rather than on the opening side wall, or b) It is positioned on at least one side wall and offset from the opening.

[0152] According to another aspect of the present invention, a method for manufacturing a foldable laminate container is provided, comprising the following steps: i. A step of folding a sheet of laminated material into a container body having a first end wall, a second end wall, and at least one side wall connected to the first end wall at a first fold and connected to the second end wall at a second fold, wherein the at least one side wall connects the first end wall and the second end wall to each other, the internal space within the container body is defined by the first end wall, the second end wall and the at least one side wall, and an opening is provided through the laminated material of the at least one side wall, the opening extending over a distance of at least about half the width of the opening side wall in a direction perpendicular to the first end wall to the second end wall; ii. In the process of sealing the laminate to the shape of the container body, at least one seal is positioned such that a) it is located on at least the first or second end wall rather than the opening side wall, or b) it is positioned on at least one side wall offset from the opening.

[0153] Any aspect of the present invention may include any features or sets of features presented in relation to other aspects of the present invention. [Brief explanation of the drawing]

[0155] Referring to Figure 1, the container according to the present invention is shown as 10 in whole. Container 10 can be used to contain articles such as viscous liquids or powders.

[0156] The container is formed from folded laminated material 12. The folded laminated material 12 defines an internal space for receiving articles.

[0157] Although the container 10 is partially shown, it is understood that the container 10 has six main surfaces that form a substantially rectangular parallelepiped body. The laminate 12 provides a barrier that prevents oxygen, moisture, and ultraviolet light from entering the container 10.

[0158] A wide opening (or wide mouth opening) 14 is provided. The wide mouth opening 14 is positioned across the top surface of the container 10 in the orientation shown, as will be described later. In this embodiment, the opening 16 is substantially circular, but in other embodiments, openings of other shapes may be used.

[0159] The first surface is provided on the first end wall 16. The first surface can be considered as the left side of the container. The second surface is provided on the second end wall (18, see Figures 2-5). The second surface can be considered as the right side. The second end wall 18 is positioned opposite the first end wall 16. The second end wall 18 is substantially the same as the first end wall 16.

[0160] The third surface of the container 10 is provided on the first side wall 20. The third surface can be considered as the top surface. The first side wall 20 is located adjacent to the first end wall 16 and the second end wall 18. The first side wall 20 is connected to or extends between the first end wall 16 and the second end wall 18.

[0161] The fourth surface of the container 10 is provided on the second side wall 22. The fourth surface can be considered as the bottom surface. The second side wall 22 is located adjacent to the first end wall 16 and the second end wall 18. The second side wall 22 is located opposite the first side wall 20.

[0162] The fifth surface of the container 10 is provided on the third side wall 24. The fifth surface can be considered as the front surface. The third side wall 24 is positioned adjacent to the first end wall 16 and the second end wall 18. The third side wall 24 is positioned adjacent to the first side wall 20 and the second side wall 22.

[0163] The sixth surface of the container 10 is provided on the fourth side wall (not shown). The sixth surface can be considered as the rear surface. The fourth side wall is located adjacent to the first end wall 16 and the second end wall 18. The fourth side wall is located adjacent to the first side wall 20 and the second side wall 22. The fourth side wall is located opposite the third side wall 24.

[0164] In this embodiment, the container 10 may consist of a single sheet of laminate 12. During manufacturing, the first and second opposing edges of the laminate sheet are connected to each other. The first and second opposing edges are overlapped and sealed to each other to form an overlap seal. At this stage, the laminate sheet forms a tubular structure having a substantially square cross-section.

[0165] The laminated material 12 is folded and sealed at both ends of the tubular structure, forming a first end wall 16 and a second end wall 18, respectively. The first end wall 16 is provided with a first end wall seal 30. The second end wall 18 is provided with a second end wall seal (36, see Figures 2-5).

[0166] The foldable tab portions 32 are provided on the first end wall 16 and the second end wall 18. In this embodiment, the foldable tab portions 32 are formed from the excess material of the first end wall 16 and the second end wall 18, as is conventional when constructing a rectangular parallelepiped container from a substantially rectangular sheet of material. The foldable tab portions 32 are folded onto the first end wall 16 and the second end wall 18. The foldable tab portions 32 are sealed to the first end wall 16 and the second end wall 18. That is, the foldable tab portions for the first end wall are positioned opposite the second end wall, and vice versa.

[0167] The container 10 has three surfaces that substantially lack a seal 30 or a folding tab portion 32. In this embodiment, the first side wall 20 (i.e., the top surface), the second side wall 22 (i.e., the bottom surface), and the third side wall 24 (i.e., the front surface) substantially lack a seal 30 or a folding tab portion 28. In other words, these surfaces are formed from a continuous, uninterrupted portion of the laminate 12.

[0168] The opening 14 is provided in the first side wall 20. That is, the opening 14 is provided on the upper surface of the container 10. In other embodiments, it will be understood that the opening 14 may be located in either or both of the second side wall 22 and the third side wall 24. The opening 14 is located at the center of the first side wall 20. In other embodiments, the opening 14 may be located off-center (offset) from the center of the first side wall 20.

[0169] In this embodiment, the opening 14 is not located on the surface that constitutes the overlap seal. By positioning the opening 14 on the side wall 20 where the seal and folding tab 32 are substantially absent, it is possible to occupy a relatively large area of ​​the container side without crossing the seal 20, thereby reducing the possibility of adverse effects on the seal and closing mechanism. The opening 14 can be much larger than the openings provided in conventional cartons. In this embodiment, the opening 14 occupies approximately 50-60% of the total area of ​​the first side wall 20.

[0170] In other embodiments, it will be understood that a relatively small opening (for example, about 40% of the side wall area) may be provided, and in yet another embodiment, a relatively large opening may be used.

[0171] The opening should be large enough to allow scooping or scooping with an utensil, rather than pouring the contents from the container. Larger openings may be preferable for ease of operation and to improve access to enclosed or protruding areas of the internal space (corners of the upper internal space), for example, to minimize the amount of residue of the contents adhering to the corners of the internal space.

[0172] The opening 14 is closed by a closure 34. In this embodiment, the closure 34 is a screw cap. In other embodiments, an alternative closure 34 may be provided. The closure 34 provides a means for opening the opening 14 and substantially resealing or reclosing it.

[0173] Referring to Figures 2 through 5, the container 10 is dimensionally configurable to accommodate or provide internal spaces of different relative shapes or sizes. The same reference numerals are used to indicate equivalent features between embodiments.

[0174] Referring to Figure 2, a second embodiment of the container according to the present invention is schematically shown as 100. Container 100 is intended as a replacement for conventional wide-mouth jars for pasta sauce. Therefore, the surface display includes images of tomatoes, which are substantially aligned between the tab and the wall. The closure is red to substantially match the display.

[0175] In this embodiment, the container 100 can be sized to hold, for example, about 300 ml to 5 liters of articles.

[0176] Referring to Figure 3, a third embodiment of the container according to the present invention is schematically shown as 200. Container 200 is intended as a replacement for a wide-mouth jam jar. Therefore, the surface display includes images of strawberries, which are substantially aligned between the tab and the wall. The closure is red to substantially match the display.

[0177] In this embodiment, the container 200 can be sized to hold approximately 100 ml to 700 ml of articles.

[0178] Referring to Figure 4, a fourth embodiment of the container according to the present invention is schematically shown as 300. Container 300 is intended as an alternative container for ground coffee packaging or coffee granule / bean containers. Therefore, the surface display includes an image of coffee beans, which is substantially aligned between the tab and the wall. The closure is brown and is made to substantially match the display.

[0179] In this embodiment, the container 300 can be sized to hold approximately 200 ml to 1000 ml of articles.

[0180] Referring to Figure 5, a fifth embodiment of the container according to the present invention is schematically shown as 400. Container 400 is a substitute for a bottle / container of pharmaceuticals or nutritional supplements. Therefore, the surface display includes an image of a tablet or capsule, and these images are substantially aligned between the tab and the wall. The closure is beige or tan in color to substantially match the display. This container is also suitable for containing, for example, chewing gum.

[0181] In this embodiment, the container 400 can be sized to hold approximately 25 ml to 150 ml of articles.

[0182] In the embodiments shown in Figures 2 to 5, the markings 40 are provided on the outer or outward-facing surface of the laminate 12. The markings 40 indicate the articles contained in the containers 100, 200, 300, and 400. In other embodiments, it will be understood that the markings 40 may include, for example, brand material and / or text information of the articles. The markings may cover part of the container surface or completely cover the container body.

[0183] In these embodiments, each closure 36 is color-coded to correspond to the indicator 40. This facilitates the identification of items within containers 100, 200, 300, and 400.

[0184] As is most clearly shown in Figure 2, the display 40 is provided on the folding tab 32 and on the container body. The display 40 on the folding tab 32 is aligned with a corresponding display 40 located on the second end wall 18. The alignment of the folding tab 32 and the display 40 on the second end wall 18 forms a consistent image across the entire right side of the container 100. That is, even though the folding tab 32 covers part of the second end wall 18, it is possible to display a complete image on the right side.

[0185] Referring also to Figure 6, the first plane 50 is shown. The first plane 50 passes through the center of the first end wall and the center of the second end wall 18 (on the left side of Figure 6). The second plane 52 is shown passing through the center of the third side wall 24 and the center of the fourth side wall (the rear of the container as seen in Figure 6). In other words, planes 50 and 52 pass through a pair of opposing end walls / side walls, respectively. The second plane 52 is perpendicular to the first plane 50. The opening 14 is positioned so as to be centered on both the first plane 50 and the second plane 52. That is, the center of the opening 14 is located at the point where the first plane 50 and the second plane 52 intersect.

[0186] Referring to Figure 7, another embodiment of the container is schematically shown as 500. Container 500 is similar to the container of the previous embodiment.

[0187] In this example, a large or wide opening 514 is provided, which is approximately the same width as the side wall on which the opening 514 is located. In this embodiment, the opening 514 occupies most of the area of ​​the opening side surface of the container 500. The diameter of the opening 514 of this container can be in the range of, for example, 7 cm to 14 cm, but integer values ​​inside and outside this range are also conceivable.

[0188] A flat wall 522 is provided at the bottom of the interior space opposite the opening 514. The flat wall 522 is substantially planar or flat along its entire length and width. The flat wall 522 has no recesses or indentations.

[0189] The seal 535 on the side facing the internal space of the laminate can be seen across the entire bottom surface.

[0190] The edge of the opening is provided with a neck or neck portion 534a for receiving a closure or screw-on cover 534. Corresponding threads are provided around the outside of the neck portion 534a. In other embodiments, a similar neck may be provided, a push-in closure may be used, or other suitable seals or closures may be provided. That is, a screw-on cover is not essential but may be preferred.

[0191] In this embodiment, the screw-on lid 534 is shown in Figure 7 in a state removed from the container. The lid 534 has a top wall (as seen from the front in Figure 7), and the area of ​​this top wall is approximately equal to or slightly larger than the opening 514. This area allows the top wall to cover the entire opening 514 when the lid 534 is connected to the neck portion 534a. A rim is provided around the periphery of the top wall, and threads that engage with the threads of the neck portion 534a are formed on the inside of this peripheral rim.

[0192] From the overhead view in Figure 7, it can be seen that the neck area is much wider than its height (the direction away from the interior space defined by the laminated walls). For example, while the height of the neck area is about 2-3 cm, its width can be 3-4 times or more.

[0193] A key advantage of the present invention is that it is an easily recyclable container with a large opening that allows for easy dispensing of any desired amount of goods. While the container embodiments described above are closed with screw-on lids, it will be understood that other types of closures, lids, and opening seals can be provided as needed. However, pump-dispenser type closures are not employed in any of the embodiments because pump dispensers are unsuitable for applications involving dispensing any desired amount of solid food, viscous food, or other solid materials from the container.

[0194] Furthermore, it will be understood that various other container embodiments are possible, and that the features of these different container embodiments can be provided in any combination. The shape of the opening is preferably circular, but can be any other suitable shape as needed. Although cubic or rectangular containers have been described above, it will be understood that containers of any suitable shape can be provided by appropriately folding and sealing the laminated material.

[0195] Referring to Figure 8, the laminate is schematically shown as 1010. Laminate 1010 can be used to form containers, such as cartons or bottles. The container can become any of the above-mentioned containers 10, 100, 200, 300, 400, or 500 by cutting, punching, or otherwise providing openings in the laminate at appropriate locations.

[0196] In a preferred embodiment, the container is a sterile container for storing food, beverages, health and beauty products, pharmaceuticals, nutritional supplements, household goods such as cleaning agents and horticultural chemicals, or automotive products such as oils, lubricants, and waxes.

[0197] The laminated material 1010 has two layers that are peelably bonded together by an adhesive. This facilitates the separation of different material layers for recycling. The relative thicknesses of the layers and adhesive in Figure 7 are not necessarily shown to actual size.

[0198] The laminate includes a first layer 1012 and a second layer 1016. The first layer 1012 and the second layer 1016 are bonded together by an adhesive 1014. The adhesive 1014 provides a certain degree of adhesion. This degree of adhesion is sufficient to keep the first layer 1012 and the second layer 1016 bonded together during use. This degree of adhesion can be overcome by manually peeling the first layer 1012 from the second layer 1016, as will be described later.

[0199] The first layer 1012 is made from aluminum or aluminum foil. The first layer 1012 provides a barrier. When molded into a container, the first layer 1012 reduces the penetration of light, oxygen, moisture, and bacteria through the laminate 1010. In other embodiments, it will be understood that the first layer 1012 may be formed from other suitable materials, such as another metal or metal alloy (which may be selected from aluminum, stainless steel, copper, iron, brass, tin, silver, titanium, nickel, and bronze). In this embodiment, the thickness of the aluminum / foil is 20-30 microns. The first layer 1012 is the terminal layer.

[0200] The second layer 1016 is made of cardboard. The second layer 1016 imparts strength and / or rigidity to the laminate. When used in container formation, the second layer 1016 should provide structural integrity to the container.

[0201] The laminated material 1010 can be used for container formation. A plan view of the laminated material 1010 used for container formation is shown in Figure 9. The first layer 1012 is placed on the second layer 1016. The laminated material 1010 is substantially rectangular. The laminated body 1010 has a first edge region 1018 and a second edge region 1020. The first edge region 1018 and the second edge region 1020 are positioned opposite each other. The laminated body has a third edge region 1022 and a fourth edge region 1024. The third edge region 1022 and the fourth edge region 1024 are positioned opposite each other. The third edge region 1022 and the fourth edge region 1024 are positioned adjacent to the first edge region 1018 and the second edge region 1020.

[0202] In Figure 9, the laminated material 1010 is understood to consist of a rectangular first layer that slightly offsets and overlaps a rectangular second layer. This means that the second edge 1020 of the first layer does not cover the second layer 1016 (for example, when viewed in plan), but the other three edges of the first layer do cover the second layer 1016. In this example, the first layer 1012 is approximately the same length as the second layer 1016, but is offset from the second layer, and the first layer is narrower than the second layer.

[0203] In other words, the second layer 1016 overlaps with the first layer 1012 at both the first edge 1018 and the third and fourth edges, and the first layer 1012 overlaps with the second layer 1016 at the second edge 1020.

[0204] The difference in the spread of the lateral extensions at the first edge 1018 and the second edge 1020 facilitates adhesion between the first edge 1018 and the second edge 1020, forming a seal 1030. As part of the seal 1030, a portion of the first layer 1012 adheres to another portion of the first layer 1012, and a portion of the second layer 1016 adheres to another portion of the second layer 1016.

[0205] Figures 10 and 11 show the seal 1030 between the first edge 1018 and the second edge 1020. The first layer 1012 at the second edge 1020 wraps around or folds over the second layer 1016. When forming the seal 1030, the second edge region 1020 comes into contact with the first edge region 1018.

[0206] To form the seal 1030, the first surface of the first layer 1012 at the first edge 1018 contacts the second surface of the first layer 1012 at the second edge 1020. The first surface of the second layer 1016 at the first edge 1018 contacts the second surface of the second layer 1016 at the second edge 1020.

[0207] That is, as shown by 1042 in Figure 5, a portion at one end of the first layer 1012 is joined to another portion of the first layer 1012 at the other end on the opposite side. As shown by 1044 in Figure 5, a portion at one end of the second layer 1016 is joined to another portion of the second layer 1016 at the other end on the opposite side.

[0208] The bond between the first layer 1012 at the first edge 1018 and the first layer 1012 at the second edge 1020 may be stronger than the bond between the first layer 1012 and the second layer 1016. The bond between the second layer 1012 at the first edge 1018 and the second layer 1012 at the second edge 1020 may be stronger than the bond between the first layer 1012 and the second layer 1016.

[0209] In this embodiment, the bonds 1042 between each face of the first layer 1012 are formed by heat sealing. The bonds 1044 between each face of the second layer 1016 are formed by heat sealing. In other embodiments, it will be understood that the bonds 1042, 1044 may be formed, for example, via an adhesive.

[0210] Seal 1030 is an airtight seal. Seal 1030 reduces the intrusion of moisture, air / oxygen, and bacteria. Seal 1030 prevents the contents of the container from leaking out of the container.

[0211] The ends of the laminated tube can be closed by forming and sealing the foldable tab portion as needed.

[0212] The laminated material 1010 includes pre-formed folds, or creases, 1032. In this embodiment, the creases 1032 allow the laminated material 1010 to be folded into a carton shape. In other embodiments, it will be understood that the laminated material 1010 can be formed at any position with creases 1032 necessary to fold the laminated material 1010 into a container shape of a desired shape and / or size.

[0213] Labeling and printing processes can be carried out before the container is constructed. That is, the laminate can be given appropriate markings, such as labels and / or other printing, before it is folded / formed into the container.

[0214] Referring to Figure 12, a second embodiment of the laminate is schematically shown as 1300. The laminate 1300 is substantially the same as that of the first embodiment, except as described below.

[0215] The laminate 1300 of the second embodiment includes a third layer 1302. The third layer 1302 contains or is composed of glassine. The third layer 1302 is the terminal layer. The third layer 1302 is peelably connected to the second layer 1016 by a second adhesive layer 1304 that provides a certain degree of adhesion. Alternatively, as shown in Figure 13, the third layer 1302 is peelably connected to the first layer 1012 by a second adhesive layer 1304 that provides some degree of adhesion. This adhesive may be the same as the first adhesive or a different adhesive. Similar to the layers of the first embodiment of the laminate, the degree of adhesion between the second layer 1016 and the third layer 1302 (or the first layer 1012 and the third layer 1302) can be overcome by an individual manually peeling off those layers.

[0216] As shown in Figures 13 and 14, the container can be manufactured from the second embodiment of the laminate 1300 in the same manner as described for the first embodiment of the laminate 1010.

[0217] In the laminate 1010 shown in Figure 13, it can be seen that the rectangular first layer covers the rectangular second layer and is slightly offset from the second layer, and the rectangular third layer covers the first layer and is also slightly offset from the first layer. This means that the second edge 1020 of the first layer does not cover the second layer 1016, and the adjacent edges of the third layer do not cover the first layer (for example, when viewed in plan). However, the other three edges of the first layer cover the second layer 1016, and the other three corresponding edges of the third layer cover the first layer. In this example, the first layer 1012 is approximately the same length as the second layer 1016, but is offset from the second layer, and the first layer is narrower than the second layer. Similarly, in this example, the third layer 1302 is approximately the same length as the first layer 1012, but is offset from the first layer, and the third layer 1302 is narrower than the first layer.

[0218] In other words, the extent of the lateral extensions of the first layer 1012 and the second layer 1016 is greater than that of the third layer 1302 in the first edge region 1018. The extent of the lateral extension of the third layer 1302 is greater than that of the first layer 1012 and the second layer 1016 in the second edge region 1020.

[0219] Each layer is connected in a manner similar to that of the previously described embodiment of the laminate 1010. Furthermore, the first surface of the third layer 1302 is bonded to the second surface of the third layer 1302 at the second edge 1020. The bond between the two surfaces of the third layer 1302 may be stronger than the bond provided by the second adhesive 1304.

[0220] When constructed or provided as a container, the third layer 1302 may form a glassine pouch container. The glassine pouch container may be peeled away from the rest of the container. The glassine pouch container is microwave-safe. The glassine pouch container may contain microwave-safe foods.

[0221] The laminates 1010 and 1300 have the advantage of being easy to recycle. Layers 1012, 1016, and 1302 are bonded in a peelable manner and can be easily separated, for example, into paper and metal recycling containers. In other embodiments, tabs can be provided on one or more layers to facilitate the separation of each layer.

[0222] Please note that laminates 1010 and 1300 do not contain polyethylene. This further simplifies the recycling process for laminates 1010 and 1300.

[0223] The embodiments described above are merely illustrative, and it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the scope of the present invention as defined in the appended claims.
