Description

[0001] This disclosure relates to cardboard or cardboard containers. Background Technology

[0002] This invention relates generally to packaging using cardboard or corrugated cardboard materials. Cardboard or corrugated cardboard is a widely used packaging material, particularly suitable for recycling, especially in paper recycling streams, and therefore particularly environmentally friendly, which may involve a reduction in non-fiber content, for example, a maximum non-fiber content of 5% by weight. However, cardboard or corrugated cardboard has limitations compared to other packaging materials such as plastic materials, particularly in terms of mechanical properties.

[0015] The lid is a critical structural element of a container. This disclosure focuses on providing a container with a lid that can be reliably manufactured and maintains its structural integrity over time. More specifically, lid corners may be subjected to vibration or tension, potentially leading to degradation of the required structural integrity of the lid. While accumulating reinforcing layers to strengthen lid corners is conceivable, this accumulation can generate mechanical tension within the corner structure, thereby creating tension in an inner layer nested within another outer layer, potentially leading to weakening or even breakage or tearing of the outer layer. This tension is particularly amplified when reinforcing layers are attached to each other before forming the relevant corner structure, resulting in the outer layer experiencing a larger radius of curvature than the inner layer nested within the outer layer, without the possibility of slipping against each other to extend the resulting elongation beyond the attachment point. While controlled initial weakening of the nested inner layer can release some tension, it has been found that controlling the initial weakening solely through fold lines, partial cuts, or cuts through is insufficient. However, it has been found that weakening the nested inner layer to release sufficient tension by cutting and removing material can prevent damage to the outer layer attached to the inner layer. However, due to the accumulation of tiny cut fragments on the cap production line, it has been found that such cut removal can cause problems on such lines, negatively impacting production line speed or even causing production line stoppages. It has been found that examples of cut shapes according to this disclosure provide reinforced multi-layer cap corners that not only address the risk of cap deterioration but also solve problems on the production line, such as those in industrial die-cutting machines for carton converters, and improve reliability and accuracy in the relevant cap forming process, more generally during carton forming, on the filling line, and when used by the end user. More specifically, this cut shape addresses several issues, such as the accuracy and predictability of positioning corner segments, releasing tension to the outer layer, avoiding the risk of undesirable flap folding due to high bending forces, and preventing the accumulation of cut debris on the production line.

[0016] Mechanically speaking, cardboard or cardboard is a relatively flexible material, meaning that the walls of containers made of cardboard or cardboard may offer little to no resistance to bending under external pressure. In some applications where resistance to bending and / or tearing is important, materials other than cardboard or cardboard can be used. However, materials other than cardboard or cardboard may not be directly recyclable. Therefore, this material choice leads to certain compromises. One object of this disclosure is to provide a container including a lid with reinforced lid corners that strengthen the entire container structure, thereby allowing the use of cardboard or cardboard in applications that would otherwise require compromises through the use of another material.

[0017] Since the container according to this specification can be shaped using folding machines that may already be in place at the manufacturing site, almost no additional funds are required at the manufacturing site to realize the structure according to this disclosure.

[0018] The lids, boxes, or containers according to this disclosure can be made of paper materials, such as those selected from cardboard, hardboard, and laminates comprising at least one layer of cardboard or hardboard. The cardboard or hardboard contains cellulose fiber materials or mixtures thereof. The materials used to manufacture the lids, boxes, or containers may contain other components such as colorants, protective varnishes, surface-reinforcing coatings, barrier coatings, preservatives, recycled fiber materials, plasticizers, UV stabilizers, oxygen barrier agents, fragrance barrier agents, and moisture-proofing agents, or mixtures thereof. In some examples, to provide the desired tear resistance and strength, the cellulose fiber length is in the range of 0.1 mm to 5 mm, preferably 1 mm to 3 mm. In some examples, the cellulose fibers are derived from a variety of sources, such as virgin softwood or hardwood, hemp, grass, corn, bagasse, sugarcane, bamboo, and others, and / or from post-production or post-consumption recycled paper and hardboard.

[0019] A lid, box, or container may include areas printed on the exterior or interior. A lid, box, or container may be made, for example, from cardboard. Suitable manufacturing processes for lids, boxes, or containers may include, but are not limited to, tubing from flat cardboard or sheets of cardboard through gluing steps, folding, or combinations thereof. A lid, box, or container may be opaque or filter certain wavelengths, for example, to protect the contents from external light. In some examples, a lid, box, or container is at least partially constructed of a paper-based material, and in some specific examples, it is constructed entirely of a paper-based material. Paper-based material herein refers to a material containing paper. Not wishing to be theoretically bound, "paper" herein refers to a material made from cellulose-based pulp. Cardboard may be made from a paper-based material having a thickness and stiffness such that it does not collapse under its own weight. Cardboard should be understood to comprise a single layer of material, while cardboard should be understood to comprise multiple layers of paper-based material. In some examples, the paper-based material includes cardboard, cardboard, or mixtures thereof, wherein preferably, cardboard includes cardboard, corrugated fiberboard, or mixtures thereof. Corrugated fiberboard includes a series of grooves. Each groove can be understood as a channel. The grooves extend parallel to each other, with the groove orientation being the direction of travel along each channel. The paper-based material can be a laminate comprising paper, cardboard, or mixtures thereof, wherein in some examples, the cardboard comprises paperboard, corrugated fiberboard, or mixtures thereof, and in some examples, at least one other material. In some examples, the at least one other material comprises a plastic material. In some examples, the plastic material comprises polyethylene (more specifically low-density polyethylene (LDPE)), polyethylene terephthalate, polypropylene, polyvinyl alcohol, or mixtures thereof. In some examples, the plastic material comprises a copolymer of monomers from ethylene and vinyl alcohol, or EVOH. A barrier material can be used as the at least one other material. The barrier material can be biaxially oriented polypropylene, metallized polyethylene terephthalate, or mixtures thereof. The at least one other material can include wax, cellulose material, polyvinyl alcohol, silica, casein-based material, or mixtures thereof. In some examples, the paper-based laminate contains more than 50% by weight, preferably more than 85% by weight, and more preferably more than 95% by weight of a paper-based laminate of a fiber-based material. In some examples, the barrier material may include a plastic material with a thickness between 10 micrometers and 60 micrometers. In some examples, the barrier material may include a plastic material with a thickness between 10 micrometers and 35 micrometers. The paper-based material may be a laminate. In some examples, the inner surface of the lid, box, or container includes cardboard, hardboard, or a mixture thereof, wherein, in specific examples, the hardboard includes a laminate of cardboard, corrugated fiberboard, and polyethylene (particularly LDPE) or a mixture thereof, and in some examples, the outer surface of the lid, box, or container, or a combination thereof, includes at least one other material. Alternatively, the at least one other material may also be laminated between two layers of paper-based material (such as cardboard or hardboard layers according to this disclosure).Not wishing to be bound by theory, at least one other material can act as a barrier against leaked liquid absorbed by the paper-based material facing the inside of the lid, box, or container, preventing or reducing contamination flow through the walls of the lid, box, or container. Other structures have been found to effectively prevent leakage of contents or protect contents from external fluids, such as showers, sinks, or handling the container or lid with wet hands. Contamination of the walls of the lid, box, or container can be unsightly to consumers or can soil storage areas. In some examples, the lid, box, or container is made of a paper-based material comprising at least one other material laminated between two layers of corrugated fiberboard. In some examples, the material for the lid, box, or container comprises a core cardboard groove material sandwiched between two layers of ordinary cardboard (or paperboard) and a polyethylene laminate. The cardboard or paperboard layers according to this disclosure may be made of or comprise recycled materials or recycled cellulose fibers. The outer surface of the lid, box, or container may include a coating or varnish. This coating or varnish can help waterproof the board or help protect the contents (such as encapsulated detergent compositions) from UV light. The coating or varnish can also help protect the outer surface of the lid, box, or container from contamination by the contents (such as encapsulated detergent compositions), for example, if a unit dose of water-soluble detergent encapsulating a liquid detergent composition leaks.

[0020] Coatings or varnishes on the inner surfaces can help prevent contents from adhering to the inner surfaces, or prevent inks, colorants, fragrances, nonionic substances, oils, greases, and other components from migrating from the contents into the board, or prevent inks or additives from migrating from the board onto the contents. In some examples, detergent-resistant varnishes or coatings may be applied to areas exposed to the contents.

[0021] Figures 1A to 1C Different exemplary containers are shown in top view. Figure 1D and Figure 1E Different exemplary containers are shown in a side view. As shown, containers according to this disclosure can take on various shapes. In one example, a cube container corresponds to... Figure 1A and Figure 1D This cubic container 100 includes a box 101, a lid 102 for the box, and a locking element 103 for holding the lid in a closed position, the locking element 103 including, for example, a generally circular actuating area. In one example, the cubic container corresponds to Figure 1A and Figure 1E This cubic container 110 includes a box 111, a lid 112 for the box, and a locking element 113 for holding the lid in a closed position. The locking element 113 includes, for example, an elongated element, such as a rubber band connecting the lid and the box. As shown, the lid includes side wings of varying proportions that can cover the side walls of the box. Figure 1EAs shown, the side wings of the cover 112 cover a large portion of the side wall of the box 111, and as... Figure 1D As shown, the side wing of cover 102 covers a small portion of the side wall of box 101. As shown, the locking element may be of different types. Figure 1A Two examples of the cubic container shown include a hinged lid with two corners 121 and 122 (hinged around edge 120, similar to the one described below). Figure 2A The container described in the text) or the four corners 121-124 (a completely removable lid, similar to the one described below) Figure 2B The lid of the container described herein. In other examples, a container with a triangular cross-section is shown, whereby the top of the lid is triangular, and the lid includes three corners 125-127. This type of container corresponds to... Figure 1B and Figure 1D Or, in another example, corresponding to Figure 1B and Figure 1E In other examples, containers are shown including lids with a single corner 128, which correspond to... Figure 1C and Figure 1D Or, in another example, corresponding to Figure 1C and Figure 1E .Although Figures 1A to 1E Many exemplary containers according to this disclosure are shown, but other examples of containers not shown herein, such as hexagons or octagons, may be considered. Figure 2A and Figure 2B Let's discuss some specific exemplary containers in more detail.

[0022] In this disclosure, for example Figure 2A or Figure 2B As shown, the exemplary container should be understood as, for example, an object that contains contents within a cavity. This container facilitates the protection, transport, storage, retrieval, and handling of contents such as consumer products. In this disclosure, the container includes a box 201. A box should be understood as, for example, a generally parallelepiped, barrel-shaped, cylindrical, cubic, partially circular, or partially elliptical three-dimensional object defining a cavity. The use of a parallelepiped box facilitates storage and transport by allowing the boxes to be stacked in a space-efficient manner. In some examples, the box may be a parallelepiped with some circular, tapered trapezium, or beveled edges. Boxes according to this disclosure include, for example, detergent products, but may also include other products, particularly other moisture-sensitive products. Boxes according to this disclosure may include a base 210, sidewalls 241-244, and an opening 215 opposite the base (note that in...). Figure 2A and Figure 2B(For ease of reading, some elements are not described repeatedly). The base according to this disclosure should be understood as a surface on which the box can lie flat when placed on a supporting surface such as a shelf or floor, and where the opening faces upward and the base faces downward in the use position so that the contents are held in the box by gravity. In some examples, the base is flat. In some examples, the base is rectangular. In some examples, the base is elliptical or circular. In some examples, the base has an embossed profile projecting inward or outward in the form of relief. The sidewalls according to this disclosure should be understood as extending from the base and connecting the base to the opening, to a transition piece, or to a lid, such as... Figure 2A Hinged cover 202, Figure 2BThe cover 212 is completely removable. It should be understood that, in addition to the sidewalls, the connection from the base to the opening may also include a transition piece. For example, the transition piece may be glued or otherwise attached to the sidewall. In some examples, the sidewall is perpendicular to the base. In some examples, the base is rectangular and has four sides, and four sidewalls extend perpendicularly from the base, each sidewall being rectangular, each sidewall connected to a side of the base by a sidewall edge, and connected to two other sidewalls of the four sidewalls by two additional sidewall edges. In some examples, the sidewalls have a shape corresponding to a square, rectangular, trapezoidal, spherical, oval, or elliptical segment. The opening according to this disclosure should be understood as an aperture providing passage to the contents contained in the box (such as, for example, a detergent product). In some examples, the surface of the opening is smaller than the surface of the base. In some examples, the surface of the opening is larger than the surface of the base in order to provide better passage, for example, by using sidewalls extending from the base at an angle greater than 90 degrees to the base. In some examples, an opening is provided after the tamper-evident feature, such as a perforation to be removed upon first use or an tamper-evident label to lock the lid to the box or tray, is removed. In some examples, the opening is located on the top panel of the box, facing the base of the box, and separated from the base of the box by at least a sidewall. The top panel and the base of the box are generally coplanar, such that the opening covers a portion of the top panel, which includes a peripheral section surrounding the opening, which is, for example, a transition between the sidewall and the opening. In some examples, the opening is rectangular. In some examples, the opening is rectangular with rounded edges. In some examples, the opening includes circular or elliptical sections. The lid according to this disclosure should be understood as an element that allows the opening of a container to be repeatedly closed or opened. In some examples, the lid may be connected to the box, for example, by a hinge (e.g., lid 202), or may be separate from the box (e.g., lid 212). The lid according to this disclosure includes a top (e.g., such as top 220) and side wings (e.g., such as side wings 230-233). It should be understood that when the lid is in the closed position, the top of the lid is intended to cover the opening of the box. In some examples, the top of the lid is rectangular. In some examples, the top of the lid is polygonal, such as a triangle, rectangle, square, hexagon, or octagon. The top of the lid may also include circular or elliptical segments, for example, as shown in the image. Figure 1CAs shown. In some examples, the lid includes a beveled edge. The lid includes side wings. It should be understood that a side wing according to this disclosure is an element attached to and extending from the top of the lid to engage one or more sidewalls of the box. The side wing helps to position the top of the lid over the opening. In some examples, the side wing extends vertically from the top of the lid. In some examples, the side wing surrounds the entire periphery of the top of the lid. In some examples, the side wing partially surrounds the entire periphery of the top of the lid, and a portion of the top of the lid is without side wings, as shown in the case of hinged lid 202, which includes side wings 230, 231, and 233 but does not include side wing 232 corresponding to the hinged portion of the lid. When the lid is in the closed position, the top of the lid can cover the opening, and at least a portion of the side wing can cover at least a specific portion of the sidewall, and the lid can be moved from the closed position to the open position. The movement of the lid can be constrained by a connection to the box (such as a hinge), or can be completely removable, for example, to provide better access to the contents of the box. The box and lid work together to facilitate the storage, transportation, and access to the contents of the container.

[0023] The container according to this disclosure includes locking elements, such as... Figure 1D Locking component 103 Figure 1E Locking component 113 Figure 2A Locking element 203 or Figure 2BOne of the locking elements 213. In this disclosure, a locking element should be understood as a mechanism that prevents or reduces the possibility of accidental opening. The locking element according to this disclosure holds the lid in a closed position. It should be understood that the locking element according to this disclosure is intended to function under normal use of the container. It should be understood that the locking element may fail to function when, for example, the box is used abnormally, or when the box is under abnormal conditions. In some examples, the locking element (such as locking element 103, 203, or 213) includes an actuator that, when the lid is in the closed position, can be moved from the locked position to the open position by applying an actuating pressure. In such examples, the actuator should be understood as a mechanical structure that undergoes movement upon actuation by an external force or actuating pressure, which, when such movement occurs, causes the locking element to open. In some examples, the actuator according to such examples is resilient and has a default position corresponding to the lid being held closed, which is overcome by an external force or actuating pressure to open the lid. In some examples, the actuator is resilient because it includes a flexible element having a default position corresponding to the lid being closed. This flexible element is pressed to open the lid, and when the pressure is released, it springs back to the default position. It should be understood that pressure is generated by applying force to a surface. Actuators according to such examples have at least two positions: an open position and a locked position. The open position corresponds to a position that allows the lid to be opened, and the locked position prevents the lid from opening or reduces the likelihood of accidental opening, such as when manipulating a container and holding its lid.

[0024] Actuator (e.g., denoted as) Figure 2A and Figure 2B An actuator (203 or 213) on the box 201 may be connected to a specific portion of the side wall of the box, which may be a portion covered by at least a portion of a side wing when the lid is in the closed position. The actuator is adjacent to a locking tab or abutment tab of the side wing in the locked position, and remains away from the locking tab in the open position. The actuator is capable of displacing an unlocking displacement distance in a direction perpendicular to the specific portion of the side wall under actuating pressure. The connection between the actuator and the specific portion of the side wall is due to the actuator's participation in locking or unlocking the specific portion of the side wall from the portion of the side wing covering that specific portion of the side wall, thereby allowing the lid to be released from the box. The side wing may include, for example, a locking tab or abutment tab formed from an inner cardboard or cardboard layer according to this disclosure. The locking tab should be understood as a mechanical element interlocked with the actuator. In some examples, the locking tab extends away from the side wing and may be in the form of a raised portion, ridge, embossing, or an additional layer of material extending from the side wing of the cover toward a specific portion of the sidewall, such that the actuator can abut against the tab when in the locked position to prevent separation of the specific portion of the sidewall from the side wing in the actuator region. In some examples, the locking tab is included within the side wing itself (e.g., see...). Figure 7Aand Figure 7B (Δ in the text). The adjacent portion according to this disclosure should be understood as contact between the actuator or a portion of the actuator and the tab, such contact preventing the cover from opening. The actuator remains away from the locking tab when in the open position to release the locking tab. This release of the locking tab allows the cover to be opened. Displacement or movement of the actuator from the locked position to the open position is achieved by applying an actuating pressure or force (directly or indirectly) to the actuator, causing the actuator to shift in a direction perpendicular to a specific portion of the sidewall by a distance sufficient to inhibit contact between the actuator and the locking tab, the distance corresponding to the displacement distance. It should be understood that the force or pressure causing this displacement can have multiple different directions, and if a component of such force or pressure is in a direction perpendicular to that specific portion of the sidewall, such different directions contribute to the displacement. Such force or pressure may also include a component parallel to the sidewall. However, the actuation is triggered by the component of such force or pressure perpendicular to that portion of the sidewall. The presence of this component perpendicular to the sidewall contributes to the locking mechanism, preventing accidental opening by applying a force parallel to the sidewall to lift the lid and thus the container. Conversely, the desired opening occurs when the consumer "pushes" the actuator and applies an unlocking force or pressure that allows the lid to open. In other words, while the consumer may apply force to the actuator in a direction not perpendicular to the sidewall, if a component of this force is perpendicular to the sidewall, this component can contribute to applying pressure that causes displacement.

[0025] This locking mechanism helps to suppress or reduce the risk of accidental opening of the lid while allowing the consumer to open it as desired. The function of this locking mechanism depends on ensuring that the actuator remains abutting the locking tab even when the lid is pulled forcefully in a direction parallel to the sidewall for transport or lifting of the consumer product. Avoiding or reducing the risk of accidental opening also applies to forces applied in a direction parallel to the sidewall, such as friction with another box positioned side-by-side according to this disclosure, or by the box tipping over during transport, or by the internal movement of the contents of the box during transport. However, forceful pulling in a direction parallel to the sidewall can affect the container's structure, for example, causing damage to the lid corners, which could lead to unintended disengagement of the locking tab from the actuator. This would result in unintended lid opening. The likelihood of such unintended lid opening is reduced when reinforced lid corners are used as described herein.

[0026] In some examples, the locking element is placed in the central region of the side wall of the box. The central region should be understood as being substantially equidistant from the opposing edges of the relevant side wall, such that the edges are perpendicular to the base of the box. In such examples, it should be understood that the locking element is positioned closer to the edge of the side wall near the opening than closer to the edge near the base, while remaining in the central region relative to the edge perpendicular to the base. In some examples, the locking element may be located on the side wall and between two edges of the side wall perpendicular to the base, with the locking element closer to one edge than the other, for example, positioned at one-third of the distance between the two edges closer to one edge. In some examples, a side wall may include two locking elements.

[0027] The contents of containers according to this disclosure (such as consumer products, e.g., detergent products) are potentially relatively heavy, especially when the container is recently purchased and thus contains a large quantity of product. While some consumers may carefully lift and transport such containers by supporting the base of the box, such lifting and transport can also be done by holding the lid of such consumer products, particularly by holding the distal end of the lid's side wings away from the top of the lid, without holding the base. Some consumers may even hold the container by inserting their fingers between the lid's side wings and the box's sidewalls. In this case, it is possible that the lid, subjected to the weight of the container's contents, experiences tension or even breakage at the corner section between such sides of the lid, resulting in the box accidentally opening, falling, and potentially spilling its contents. Such situations should be avoided. In addition to preventing such unintentional release, the container's structure should maintain or improve ergonomics when opened and prevent or reduce structural deformation under excessive or repeated forces applied to the container, such as during transport, compression by other objects in grocery bags, external pressure, drops, or in cases where it is designed to withstand multiple opening and closing cycles during use. Simultaneously, the container can be carefully designed to protect the environment. The container according to this disclosure is intended to take these various aspects into consideration.

[0028] The container lid includes at least a first wing and a second wing, wherein the first wing and the second wing intersect at a first corner section along a direction perpendicular to the top of the lid. This corner section may, for example, correspond to... Figures 1A to 1C Corner of the cover 121-128 Figure 2A or Figure 2B The corner between adjacent flanks 230 and 233, Figure 2A or Figure 2B The corner between adjacent flanks 230 and 231 Figure 2B The corner between adjacent flanks 232 and 233, or Figure 2BThe corner between adjacent flanks 232 and 231. In practice, it should be understood that the first and second flanks are adjacent and share a first corner segment. In some examples, the corner is a 90-degree corner, but in other examples, the corner may be at a different angle. The first corner segment should be understood as straight, defined at one end by the top of the cover and at the other end by the distal ends of the first and second flanks away from the top of the cover. Such a first corner segment along a corner direction perpendicular to the top of the cover should be understood as along a direction substantially perpendicular to a plane generally aligned with the top of the cover.

[0029] Figure 3A and Figure 3B This represents a three-dimensional cross-sectional view of an exemplary cover corner (e.g., cover corner 121, 125, or 128) according to the present disclosure, the cross-section being along a plane S parallel to the first corner segment 301. Figure 3A This is the view taken from the outside of the lid (meaning the view taken from the outside and top of the container with the lid closed and the container lying flat on its base), while Figure 3B This is a view taken from the inside of the lid (in this case, the lid is inverted for better readability). The lid in this example includes a top 302, a first wing 303, and a second wing 304.

[0030] like Figure 3B The first corner section 301 shown includes a first outer cardboard or hardboard layer 310 folded along the corner direction D and a first inner cardboard or hardboard layer 320 folded along the corner direction D. It should be noted that in other examples, one or more additional layers may be provided, each layer either nested within or overlapping the first outer or inner layer, or sandwiched between the first outer and inner layers. The first outer layer 310 overlaps with the first inner layer 320 at the first corner section 301, wherein the first outer layer is connected to the first inner layer along a first longitudinal fold line 333 parallel to the first flank 303 and along a second longitudinal fold line 334 parallel to the second flank 304, the first and second longitudinal fold lines defining the respective distal ends of the first flank 303 and the second flank 304 away from the top 302. This layer overlap contributes to achieving the desired corner robustness, stiffness, and / or tear resistance. It should be noted that the first inner layer and the first outer layer may be derived from the same sheet of the same material before being folded along the longitudinal fold line to define the inner and outer layers.

[0031] In some examples, the longitudinal fold lines described herein as parallel to the side wings (such as exemplary longitudinal fold lines 333 or 334) may also be parallel to the plane corresponding to the base or top of the cover, for example, as... Figure 3A , Figure 3B , Figure 2A or Figure 2BAs shown. In such cases, for example, the longitudinal lines follow a specific direction parallel to both the sides and the top of the cover. However, Figure 3C Different configurations according to this disclosure are shown, wherein the lid 3002 of the box 3001 includes a first side wing 3003, a second side wing 3004, a first corner segment 3011, a first longitudinal fold line 3033 parallel to the first side wing 3003, and a second longitudinal fold line 3034 parallel to the second side wing 3004, wherein the second longitudinal fold line 3034 is parallel to both the second side wing and the top of the lid, and wherein the first longitudinal fold line 3033 is parallel to the first side wing 3003 but forms an angle with respect to the top of the lid. Figure 3D In the example configuration (without reference numerals), both the first and second longitudinal fold lines are angled to the top of the lid. Other configurations not shown here may be considered. It should also be noted that the top and base of the lid do not necessarily have to be parallel to each other.

[0032] For example, Figure 3B As shown, the first inner layer and the first outer layer are attached to each other at at least one point (such as point 350) between the longitudinal fold lines 333 and 334 and the top of the cap. This attachment can be achieved by one or more of adhesive bonding, heat sealing, stitching, or other attachment methods. This attachment helps prevent a user from inserting, for example, a finger between the inner and outer layers. Separating the inner and outer layers would actually negatively impact corner robustness. In some examples, the attachment point is a single point. In some examples, the first inner layer and the first outer layer are attached to each other at at least two points between the longitudinal fold lines and the top of the cap, with the first corner segment located between these at least two points, thereby improving the attachment between the two layers. It should be noted that while such layer attachment on either side of the respective corner segment promotes robustness, this attachment further limits the flexibility of the corner structure, thus further benefiting from the introduction of the cutout according to this disclosure.

[0033] like Figure 3BAs shown, the first outer layer 310 is a continuous layer at the first corner section, while the first inner layer includes a first cut shape 340 at the first corner section. In this example, there is no layer between the first outer layer and the first inner layer, such that a portion 310a of the first outer layer is visible through the cut 340. This cut shape is defined by a periphery corresponding to the material removed from the first inner layer, the removal of which releases pressure in the corner region, thereby avoiding or reducing the risk of damage to the first outer layer in such regions. A continuous layer should be understood as a layer that forms a complete unit in the corner region, in other words, a layer that is not interrupted by a cut. In some examples, the continuous first outer layer includes uninterrupted fibers comprising a fiber portion contained in a first wing and another fiber portion of the same fiber contained in a second wing. This uninterrupted fiber of the outer cardboard or hardboard layer bridges the cut shape in the inner cardboard or hardboard layer, thereby providing corner robustness.

[0034] like Figure 3B As shown, the first cut shape 340 extends along the first corner segment (i.e., along direction D). This extension has the effect of facilitating folding along such direction D to form a corner. It should be noted that the extension should be understood as the entire cut shape having a maximum length along the corner direction D, which is longer than the maximum width along a direction perpendicular to the corner direction D. It should be noted that due to the folding, the cut can have the resulting three-dimensional shape. Although the cut 340 is shown as having a generally elliptical or oval shape, other shapes can be considered, such as... Figures 4A to 4H As shown. In Figures 4A to 4H In this context, cut shapes are represented as planar, and they can actually be produced or manufactured from flat sheets corresponding to cardboard or cardboard layers. However, once folded along the corner direction D, such cut shapes take on a three-dimensional shape to form a corner. Some cut shapes (such as...) Figure 4B The exemplary shapes shown can remain two-dimensional because they will remain on a single wing of the two wings while being adjacent to the corner segment. Figure 4A In the cut, the shape is a rhombus extending in the corner direction D. Figure 4B In the cut, the shape is a semi-ellipse extending in the corner direction D. Figure 4C In the cut, the shape is a hexagonal shape that extends in the corner direction D. Figure 4D In this context, the cut shape is a combination of curves and polygons that produce a shape that elongates in the corner direction D. Figure 4E In the diagram, the cut shape is another hexagonal shape that extends in the corner direction D. Figure 4F In this context, the cut shape is a combination of rectangles and disks, resulting in a shape that elongates in the corner direction D. Figure 4G In this context, the cut shape is a combination of rhomboid segments that produce an overall shape elongated in the corner direction D. Figure 4H In this context, the cut shape is a combination of beaded or circular segments that produce an integral shape elongated in the corner direction D. It should be understood that each shape has a maximum width W along a direction perpendicular to direction D, which is less than its maximum length L along direction D. In some examples, the maximum width W of the cut shape along the direction perpendicular to direction D is less than 90% of the maximum cut length L along direction D. In some examples, the maximum width W of the cut shape along the direction perpendicular to corner direction D is less than 70% of the maximum cut length L along corner direction D. In some examples, the maximum width W of the cut shape along the direction perpendicular to corner direction D is less than 50% of the maximum cut length L along corner direction D. In some examples, the maximum width W of the cut shape along the direction perpendicular to corner direction D is less than 30% of the maximum cut length L along corner direction D. In some examples, the maximum width W of the cut shape along the direction perpendicular to corner direction D is less than 10% of the maximum cut length L along corner direction D. It should be understood that the length L remains linear after folding, while the width W can be composed of two segments after folding (one along the first wing and the other along the second wing). Note the case where the cut shape is formed by different segments that are separate from each other (see, for example, [reference needed]). Figure 4G or Figure 4H The elongation is defined by considering the total maximum length and the total maximum width, including the material portion between the cut sections (such as...). Figure 4G and Figure 4H (Part M). In some examples, the cut shape formed by the different segments that are separate from each other is associated with a relatively long corner segment. Although the cut shape including the different segments that are separate from each other is represented herein as having different segments extending along the corner direction D, other configurations may also be considered. In some examples, the first cut shape includes one or more of the following: elliptical, oval, rhomboid, crescent-shaped, elongated bead-shaped, or a superposition of any of these shapes. It should be noted that in some examples, the first cut shape includes one or more apexes or vertexes that coincide with the first corner segment (see, for example...). Figure 3B The cut shape is 340, or Figure 4A , Figure 4B , Figure 4C , Figure 4D , Figure 4F , Figure 4G and Figure 4H The cut shape (represented in the diagram) improves the precision with which the corner will be defined along the corner direction D in which it is formed. In some examples, the apex or vertex is positioned on the opposite side of the cut shape along the corner direction D, for example, to help guide folding along such a corner direction D. In some examples, the cut shape is symmetrical about a plane perpendicular to the corner direction D.

[0035] According to this disclosure, the first cut shape terminates at a distance greater than 0.5 cm from both the first and second longitudinal fold lines. In other words, the point of the cut shape closest to either the first or second longitudinal fold line is a distance D1 from such fold lines, such as at least 0.5 cm for the exemplary cut 340. This minimum distance allows for benefit from the cut's effect in reducing tension while limiting its impact on corner robustness. In some examples, the first cut shape terminates at a distance greater than 0.7 cm from both the first and second longitudinal fold lines. In some examples, the first cut shape terminates at a distance greater than 1 cm from both the first and second longitudinal fold lines. In some examples, the first cut shape terminates at a distance greater than 1.5 cm from both the first and second longitudinal fold lines. It should be noted that in some examples, the point of the cut shape closest to either the first or second longitudinal fold line is the apex or vertex of the cut shape that coincides with the first corner segment, thereby providing corner robustness and improved folding accuracy. In some examples, the first cut shape terminates less than 3 cm away from the first longitudinal fold line and the second longitudinal fold line in order to remove a sufficient amount of material.

[0036] In some examples, the first cut shape according to this disclosure terminates more than 0.5 cm away from the top of the cap to further increase robustness. In some examples, the first cut shape terminates more than 0.7 cm away from the top. In some examples, the first cut shape terminates more than 1 cm away from the top. In some examples, the first cut shape terminates more than 1.5 cm away from the top. In some examples, the first cut shape terminates less than 3 cm away from the top to remove a sufficient amount of material.

[0037] The first cut shape according to this disclosure has a maximum total span of at least 0.3 mm, preferably at least 2 mm, along the first and second side wings and in a plane parallel to the top. This maximum total span is also shown, for example, as... Figures 4A to 4HThe width W in the figure. Providing this maximum total span facilitates the removal of material cuts during manufacturing, particularly using pins, which can be inserted into the cut material to allow high-speed removal of such cut material from the production line (e.g., from an industrial die-cutting machine), thereby avoiding the accumulation of cut material debris that would otherwise adversely affect manufacturing productivity. In some examples, the first cut shape according to the present disclosure has a maximum total span of at least 3 mm along the first and second side wings and in a plane parallel to the top. In some examples, the first cut shape according to the present disclosure has a maximum total span of at least 4 mm along the first and second side wings and in a plane parallel to the top. In some examples, the first cut shape according to the present disclosure has a maximum total span of at least 5 mm along the first and second side wings and in a plane parallel to the top. In some examples, the first cut shape according to the present disclosure has a maximum total span of at least 6 mm along the first and second side wings and in a plane parallel to the top. In some examples, the first cut shape according to this disclosure runs along the first and second flanks and has a maximum total span of less than 1 cm in a plane parallel to the top to remove a sufficient amount of material while maintaining structural rigidity. As described above in the context of width W, once folded, the span can be formed in two segments (one along the first flank and the other along the second flank). In some examples, this span is related to the inner layer thickness, whereby a thicker inner layer benefits from a wider or higher span cut to release the increased tension corresponding to the thicker layer. In some examples, a span of 0.3 mm to 1 mm is used for plain (non-corrugated) layers. In some examples, a span of 1 mm to 4 mm is used for corrugated layers. In some examples, a span of 0.8 mm to 1.2 mm is used for N (0.5 mm) grooved layers. In some examples, a span of 1 mm to 1.5 mm is used for F (1 mm) grooved layers. In some examples, a span of 1.5 mm to 2 mm is used for E (1.5 mm) grooved layers. In some examples, a span of 0.3 mm to 4 mm is used for the B (3 mm) groove layer.

[0038] The length of the first cut shape according to this disclosure corresponds to Figures 4A to 4H The length L in the middle is less than the height of the first inner layer along the first corner section (such as...). Figure 3B The exemplary height H1) is 90% and greater than 10% of the height of the first inner layer. This allows the benefits of the cut to be received without significantly affecting the robustness of the first inner layer along the first corner segment. In some examples, the length of the first cut shape according to the disclosure is less than 80% and greater than 20% of the height of the first inner layer along the first corner segment. In some examples, the length of the first cut shape according to the disclosure is less than 70% and greater than 30% of the height of the first inner layer along the first corner segment.

[0039] In some examples, the first cut shape extends beyond a 2mm diameter profile. As discussed in the context of width W and the maximum total span of the cut shape, while this 2mm diameter could correspond to a disk of material removed during the fabrication of the cut, this removed disk could be three-dimensional in shape during corner formation. This 2mm diameter profile is... Figures 4A to 4H The dashed disc in the diagram represents this. This extension of the profile beyond 2 mm in diameter allows for the capture of cut material during cut fabrication using a pin with a diameter smaller than the profile diameter. This capture of cut material allows for its removal. In some examples, the cut material can be removed by alternative methods (e.g., by blowing), but such alternative methods may offer less control over removal. In some examples, the first cut shape extends beyond a 3 mm diameter profile. In some examples, the first cut shape extends beyond a 4 mm diameter profile. In some examples, the first cut shape extends beyond a 5 mm diameter profile. Providing a larger extension in this way helps to lock and control the removal of cut material. In some examples where the cut shape includes multiple separate cut segments, each cut segment extends beyond a 2 mm, 3 mm, or 4 mm diameter profile, allowing each segment to be locked. In some examples where the cut shape includes multiple separate cut segments, each cut segment extends within a 30 mm diameter profile, ensuring the inner layer remains robust. In some examples where the cut shape includes multiple separate cut segments, each cut segment extends within a 1cm diameter profile, ensuring the inner layer remains robust while preventing unintentional pinching of the user's fingers.

[0040] In some examples, especially as Figure 5 As shown, it is based on Figure 3B The example shown, and as a view along a plane (such as plane S), comprises a first outer layer and a first inner layer, both comprising corrugated cardboard as shown in section 510, the corrugated cardboard including grooves extending parallel to the corner direction D. This configuration has been found to be particularly robust while also facilitating corner formation. It should be noted that this configuration has been found to be particularly suitable for first cutout shapes including one or more apexes or vertexes coinciding with the first corner segment, in order to provide corner forming accuracy where the grooves may not be precisely aligned with the corner direction and may tend to shift the fold line and deviate it from the desired corner direction.

[0041] like Figure 5 As shown, the first inner layer and the first outer layer can be attached to each other along at least two attachment sections 550 located between the longitudinal fold line and the top of the cover, wherein a first corner section is located between the at least two attachment sections. For example, such attachment can be created by applying adhesive with a glue gun before folding the layers together and before forming the corner section by folding.

[0042] In some examples, the inner or outer cardboard or hardboard layer according to this disclosure is a common board layer or a corrugated fiberboard layer. In some examples, the cardboard or hardboard layer according to this disclosure is made of common board containing recycled components, with a gsm (grams per square meter) ranging from 300 to 900, preferably from 500 to 700. In some examples, the cardboard or hardboard layer according to this disclosure is made of natural common board, or does not contain recycled components, with a gsm (grams per square meter) ranging from 250 to 600, preferably from 300 to 500.

[0043] In some examples, especially as Figure 6 As shown, the diagram is based on Figure 3B The example shown has along such as Figure 1A The view is a plane S2 rather than plane S, and thus shows two corners of an exemplary lid. In this example, the side of the lid is shown. The container includes a third wing 605, wherein the second wing 304 and the third wing 605 intersect at a second corner segment 601 along a direction parallel to the corner direction D. The second corner segment includes a first outer layer 310 folded along a direction parallel to the corner direction and a first inner layer 320 folded along a direction parallel to the corner direction, wherein the first outer layer overlaps with the first inner layer at the second corner segment 601, wherein the first outer layer is connected to the first inner layer along a third longitudinal fold line 635 parallel to the third wing. The line defines the distal end of the third side wing away from the top 302, wherein the first outer layer is a continuous layer at the second corner section and wherein the first inner layer includes a second cutout shape 640 at the second corner section, wherein the second cutout shape extends along the second corner section, wherein the second cutout shape terminates more than 0.5 cm away from the second and third longitudinal fold lines, wherein the second cutout shape extends along the second and third side wings and has a maximum total span of at least 0.3 mm, preferably at least 2 mm, in a plane parallel to the top, and wherein the length of the second cutout shape along the second corner section is less than 90% and greater than 10% of the height of the first inner layer. Providing such multiple cutout shapes allows for multiple reinforced corners to be provided in the same cap according to this disclosure.

[0044] like Figure 6 As shown, the first inner layer and the first outer layer can be attached to each other by a sew 650 located between the longitudinal fold line and the top of the cover.

[0045] The shape of the second cut can vary in its characteristics, as described in the context of the first cut shape. In some exemplary embodiments, the first cut shape and the second cut shape are the same. In some exemplary embodiments, the first cut shape and the second cut shape are different.

[0046] Figure 7AAnother exemplary container is shown. Figure 7A based on Figure 6 The example shown in the middle has a path along such as Figure 1A A planar view of plane S3, the container includes at least a fourth wing 706, wherein the first wing 303 and the fourth wing 706 intersect at a third corner segment 701 along a direction parallel to the corner direction D. The third corner segment includes a second outer cardboard or cardboard layer 710 folded along a direction parallel to the corner direction and a second inner cardboard or cardboard layer 720 folded along a direction parallel to the corner direction, wherein the second outer layer overlaps with the second inner layer at the third corner segment 701, wherein the second outer layer is connected to the second inner layer along a first longitudinal fold line 333 and a fourth longitudinal fold line 736 parallel to the fourth wing, the fourth longitudinal fold line defining the fourth wing. The second outer layer is a continuous layer at the third corner section, and the second inner layer includes a third cut shape 740 at the third corner section, wherein the third cut shape extends along the second corner section, wherein the third cut shape terminates more than 0.5 cm away from the first longitudinal fold line and the fourth longitudinal fold line, wherein the third cut shape has a maximum total span of at least 0.3 mm, preferably at least 2 mm, along the first and fourth side wings and in a plane parallel to the top, and wherein the length of the third cut shape along the third corner section is less than 90% and greater than 10% of the height of the second inner layer.

[0047] like Figure 7A As shown, the first inner layers 320 and 720 and the first outer layers 310 and 710 can be attached to each other along a plurality of attachment segments 750 located between the longitudinal fold line and the top of the cover, wherein each corner segment is located between at least two attachment segments. Figure 5 As shown, this attachment can be achieved by applying adhesive with a glue gun before the corresponding layers are folded together and before different corner sections are formed by folding.

[0048] The shape of the third cut can vary in its characteristics, as described in the context of the first or second cut shape. In some exemplary embodiments, the first, second, and third cut shapes are the same. In some exemplary embodiments, the first, second, and third cut shapes are different.

[0049] Although not described in detail herein, a fourth (or even further additional) cover corner may be provided, such as, for example Figure 1A The corner 123.

[0050] Based on any example described in this article, and in particular as Figure 7A The first wing shown ( Figure 7A Depend on Figure 7B Supplement the cross-sectional view along plane S4, as follows: Figure 7A As shown, plane S4 (parallel to the second side wing 304) includes a first main wing 730 and a first main wing fold line 731 connecting the first main wing to the top 302, wherein a portion 310b of the first outer layer is sandwiched between the first main wing 730 and the first inner layer 320 to form a portion of the first side wing 303. Providing the first main wing allows for further reinforcement of the cover. While various configurations may be provided, according to this disclosure, a specific example blank of an exemplary cover for presenting such a main wing and four cover corners is provided. Figure 7C In some examples not shown in this document, the first inner layer is sandwiched between the main flap and the first outer layer, wherein when the lid is closed, the main flap will be closer to the corresponding box sidewall than the first inner layer.

[0051] For example, Figure 2B As shown, in some examples, the top of the lid is rectangular, where the second wing (wing 230 in this example) is longer than the first wing (wing 231 or wing 232 in this example), and the lid is symmetrical along a plane parallel to the second wing. In this configuration, the lid may include, for example, a cutout at each corner. The advantage of the symmetry of such a lid is that it can be placed on the box in a flip-over manner.

[0052] In some examples, such as Figure 3B , Figure 5 , Figure 6 , Figure 7A and Figure 7B As shown, the first inner layer forms adjacent tabs for the locking element; such a first inner cardboard layer provides both locking and reinforcement functions. In such examples, at least certain portions of the second wing (such as...) Figure 7B In the exemplary specific portion 310c) shown, the first inner layer is shorter than the first outer layer along a direction parallel to the corner direction. In such a configuration, a specific portion of the second wing may include an actuating region of the locking element, such as a hole, etc. Figure 7C The hole 750 shown is shown.

[0053] In some examples, such as Figure 8 The blank shown (similar to) Figure 7C In the blank), in at least a first portion 320a of the first side wing, the first inner layer 320 has the same height Hi as the first outer layer along a direction parallel to the corner direction. This configuration can suppress discontinuities (such as discontinuities Δ) caused by this height difference along such portions. This configuration of equal height can be applied to a selection of side wings or all side wings. Figure 8In this design, the two resulting short flanks will have the same inner and outer layer heights, while the two resulting long flanks will be discontinuous, allowing for locking tabs and actuation areas in each long flank. In some examples not shown herein, the lid may also include a support element attached to the top panel, with the sidewalls of the box sandwiched between the support element and the corresponding flank of the lid, providing further robustness, as described, for example, in EP22167961.6 filed April 12, 2022.

[0054] The purpose of this disclosure is to resolve, on the one hand, the apparent contradiction between the use of materials for containers that resist accidental opening and the use of particularly environmentally friendly materials for containers.

[0055] The container can be made of rigid or cardboard material, flexible or cardboard material, or a mixture thereof. In some examples, each layer of material forming the box or lid has a wall thickness greater than 300 micrometers and less than 6 mm. In some examples, each layer of material forming the box or lid has a wall thickness greater than 1 mm and less than 2 mm. The container can be made of paper material, bio-based material, bamboo fiber, cellulose fiber, cellulose-based or fiber-based material, or a mixture thereof. The container can be made of material including recycled material, such as recycled cellulose fiber-based material. In some examples, the container is made of C (3.2 mm) grooved corrugated cardboard. In some examples, the container is made of double-walled cardboard, and in some examples, it is made of double-walled cardboard with each double-wall layer being at most 5 mm thick.

[0056] In some examples, the flanks of the lid cover approximately 30% of the sidewalls of the box. In this case, 30% corresponds to the ratio between the height of one side flank perpendicular to both the top of the lid and the base of the box, and the height of the other sidewall perpendicular to both the top of the lid and the base of the box. In one example, the flanks completely surround the sidewalls around the opening. This coverage of the flanks helps ensure the placement of the lid, structural flexibility, and protection of the contents. In some examples, the flanks cover at least 50% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover at least 75% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover at least 90% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover 100% of the sidewalls when the lid is in the closed position. Increasing the flank coverage increases robustness. In some examples, the flanks cover up to 90% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover up to 80% of the sidewalls when the lid is in the closed position. In some examples, the wing covers up to 70% of the sidewall when the lid is in the closed position. Reducing wing coverage can facilitate container opening by providing gripping surfaces on both the lid and the box sidewall. In some examples, the manufacturing process includes providing different box sizes, such as boxes with sidewall heights of 10cm, 11.5cm, 13.5cm, or 16cm, whereby each box can be fitted with the same lid suitable for all provided box sizes, such as a lid with a wing height of 7cm. In some examples, the wing height exceeds 3cm. In some examples, the wing height exceeds 5cm. In some examples, the wing height exceeds 6cm. In some examples, the wing height is 9cm or greater. In some examples, the wing height is 12cm or greater. In some examples, the box sidewall has a sidewall height of 30cm or greater along a direction perpendicular to the base. In some examples, the box sidewall has a sidewall height of up to 40cm along a direction perpendicular to the base.

[0057] This disclosure also provides a consumer product comprising a detergent product and a container according to any of the examples described herein, wherein the container includes the detergent product.

[0058] In this disclosure, consumer products should be understood as products specifically provided to end consumers. Such consumer products are, for example, available for purchase in supermarkets, and can be stored at home by end consumers. Consumer products can be supplied in large quantities, and therefore environmental considerations should be taken into account in their design. The design of consumer products should also consider transportation to retail stores. The design of consumer products should also consider shelf storage in retail stores. The design of consumer products should also consider transportation from retail stores to consumers' homes. The design of consumer products should also consider storage in the private homes of end consumers. The design of consumer products should also consider use in the private homes of end consumers. The design of consumer products should also consider disposal.

[0059] Consumer products according to this disclosure include detergent products. Detergent products should be understood in this disclosure as products containing surfactants. Detergent products may also contain bleach or other ingredients. Exemplary detergent product compositions are described in more detail herein. In some examples, detergent products comprise unit-dose detergent sachets, preferably water-soluble unit-dose detergent sachets, more preferably flexible water-soluble unit-dose detergent sachets. Exemplary unit-dose detergent sachets are described in more detail herein.

[0060] In some examples, the consumer product includes at least one water-soluble unit dosage form and a container. The consumer product can be sold "as is," meaning it is an item a consumer takes from a shelf. Alternatively, the consumer product can be contained as a unit of a multi-component product. For example, more than one consumer product can be contained within an outer package, and multiple packages of consumer products can be sold together in a single purchase. The consumer product may include aesthetic elements, such as shrink sleeves or labels attached to the container. Alternatively, the container may be colored or printed with aesthetic elements or informational printouts (such as instructions for use).

[0061] In some examples, the water-soluble unit-dose article includes at least one water-soluble film oriented to form at least one unit-dose internal compartment, wherein the at least one unit-dose internal compartment contains a detergent composition. The water-soluble film and detergent composition are described in more detail below. In some examples, the consumer product includes at least one water-soluble unit-dose article, in some cases at least two water-soluble unit-dose articles, in some cases at least 10 water-soluble unit-dose articles, in some cases at least 20 water-soluble unit-dose articles, in some cases at least 30 water-soluble unit-dose articles, in some cases at least 40 water-soluble unit-dose articles, and in some cases at least 45 water-soluble unit-dose articles. In some examples, the water-soluble unit-dose article is in the form of a sachet. In some examples, the water-soluble unit-dose article contains a single dose of composition, the volume of which is sufficient to provide benefit in the final application. In some examples, the water-soluble unit-dose article includes a water-soluble film shaped such that the unit-dose article includes at least one internal compartment surrounded by the water-soluble film. The at least one compartment contains a cleaning composition. The water-soluble membrane is sealed to prevent leakage of the cleaning composition from the compartments during storage. However, when the water-soluble unit dose article is added to water, the water-soluble membrane dissolves, releasing the contents of the internal compartments into the washing liquid. The unit dose article may include more than one compartment, at least two compartments, or at least three compartments, or at least four compartments, or even at least five compartments. The compartments may be arranged in a superimposed orientation, i.e., one positioned on top of another. Alternatively, the compartments may be positioned in a side-by-side orientation, i.e., one immediately adjacent to the other. The compartments may be arranged in a "tire and rim" orientation, i.e., the first compartment is positioned close to the second compartment, but the first compartment at least partially surrounds the second compartment, but does not completely enclose the second compartment. Alternatively, one compartment may be completely enclosed within another compartment. In some examples, the unit dose article includes at least two compartments, one of which is smaller than the other. In some examples, the unit dose article comprises at least three compartments, two of which may be smaller than the third compartment, and in some examples, the smaller compartments are stacked on top of the larger compartments. In some examples, the stacked compartments are oriented side-by-side. In some examples, each individual unit dose article may have a weight between 10 g and 40 g, or even between 15 g and 35 g. The water-soluble membrane is capable of dissolving or dispersing in water. Before being formed into a unit dose article, the water-soluble membrane has a thickness of 20 micrometers to 150 micrometers in some examples, 35 micrometers to 125 micrometers in others, 50 micrometers to 110 micrometers in still others, and about 76 micrometers in yet still others. Exemplary water-soluble membrane materials include polymeric materials. The membrane material can be obtained, for example, by casting, blow molding, extrusion, or blow extrusion of the polymeric material.In some examples, the water-soluble film comprises a polyvinyl alcohol homopolymer or a polyvinyl alcohol copolymer, such as a blend of polyvinyl alcohol homopolymers and / or polyvinyl alcohol copolymers, wherein the polyvinyl alcohol copolymer is selected from sulfonated and carboxylated anionic polyvinyl alcohol copolymers, particularly carboxylated anionic polyvinyl alcohol copolymers, such as a blend of water-soluble polyvinyl alcohol homopolymers and carboxylated anionic polyvinyl alcohol copolymers, or alternatively a blend of polyvinyl alcohol homopolymers. Alternatively, the polyvinyl alcohol in the water-soluble film consists of anionic polyvinyl alcohol copolymers, particularly carboxylated polyvinyl alcohol copolymers. In some examples, the water-soluble film is one supplied by Monosol under trade references M8630, M8900, M8779, and M8310. In some examples, the film may be opaque, transparent, or translucent. The film may include printing areas. The printing areas may be implemented using techniques such as flexographic printing or inkjet printing. The film may contain an aversive agent, such as a bittering agent. Suitable bittering agents include, but are not limited to, naringin, sucrose octaacetate, quinine hydrochloride, benzyl dinatamine, or mixtures thereof. Example levels of aversive agents include, but are not limited to, 1 ppm to 5000 ppm, 100 ppm to 2500 ppm, or 250 ppm to 2000 ppm. Water-soluble films or water-soluble unit-dose products, or both, may be coated with a lubricant. In some examples, the lubricant is selected from talc, zinc oxide, silica, siloxanes, zeolite, silicic acid, alumina, sodium sulfate, potassium sulfate, calcium carbonate, magnesium carbonate, sodium citrate, sodium tripolyphosphate, potassium citrate, potassium tripolyphosphate, calcium stearate, zinc stearate, magnesium stearate, starch, modified starch, clay, kaolin, gypsum, cyclodextrin, or mixtures thereof.

[0062] In some examples, the container includes a first portion, wherein the first portion includes a first compartment containing at least one water-soluble unit dose product.

The liquid laundry detergent compositions described herein may have any suitable viscosity, depending on factors such as the formulation ingredients and the purpose of the composition.

[0064] Figure 9 An exemplary method for manufacturing a container according to any example described herein is shown. This exemplary method includes, in frame 901, using a cutting ruler of a die to cut a first slit shape into a first inner layer. In some examples, during frame 901, the first inner layer and the first outer layer are part of the same unfolded planar sheet, such as... Figure 7C or Figure 8The exemplary method also includes, in frame 902, punching the cut material corresponding to the cut shape of the first cut using one or more pins. This prevents uncontrolled movement of the cut material once it has been removed. It should be noted that this punching 902 can occur before, after, or during the cut 901. The exemplary method also includes, in frame 903, completely removing the cut material from the first inner layer using one or more pins. This allows for the avoidance of accumulating cut material debris on the production line. The exemplary method also includes, in frame 904, folding the first outer layer and the first inner layer together along a first longitudinal fold line and a second longitudinal fold line, wherein the first longitudinal fold line and the second longitudinal fold line are aligned during folding. This prepares the corresponding side wings. The method also includes, in frame 905, attaching the first outer layer and the first inner layer together. This attachment may, for example, involve gluing, wherein adhesive may be applied to one or both layers prior to folding according to frame 904. This attachment may, for example, involve stitching once folding according to frame 904 has occurred. This attachment may, for example, involve heat sealing once the folding according to frame 904 has occurred, such as in cases where the inner and outer layers include surface heat-sealable layers. The exemplary method also includes, in frame 906, forming a first corner segment by folding the attached first outer and first inner layers along the corner direction, wherein the first inner layer is nested into the first outer layer by folding. This allows for the formation of a reinforced corner without applying excessive tension to the first outer layer. Due to the application of frames 901-906, the first cut shape is according to any of the examples described herein, wherein the first cut shape extends along the first corner segment, terminates at least 0.5 cm away from the first and second longitudinal fold lines, has a maximum total span of at least 2 mm along the first and second side wings and in a plane parallel to the top, and has a length along the first corner segment less than 90% and greater than 10% of the height of the first inner cardboard layer. In some examples, the formation of the first corner section is performed around a removable mandrel inserted along the first portion of the first side wing. In some examples, to avoid the mandrel "jamming," as shown by blank 8, a first inner cardboard or cardboard layer having the same height as the first outer cardboard or cardboard layer is provided in at least the first portion of the first side wing in a direction parallel to the corner direction to facilitate movement of the mandrel in a direction parallel to the corner direction, thereby preventing the mandrel from jamming onto adjacent tabs. Such a mandrel can also be used for folding main flaps, such as the main flap 730 described above.

[0065] Such exemplary methods can be applied to one or more corner sections of any exemplary container described herein.
