Description

The present invention relates generally to packaging using cardboard materials. Cardboard is a widely used packaging material, which is particularly suitable for recycling, especially in the paper recycling stream, where it may have a reduced non-fiber content, e.g. a maximum non-fiber content of 5% by weight, and is therefore particularly environmentally friendly. However, cardboard has limitations compared to other packaging materials, such as plastic materials, especially as far as the mechanical properties are concerned.

Cardboard is, mechanically speaking, a relatively flexible material, which means that the walls of a container made of cardboard may offer little resistance to bending under external pressure. In some applications where resistance to bending is important, materials other than cardboard can be used. However, materials other than cardboard may not be easily recyclable. The choice of such materials is thereby the result of a compromise. The aim of the present disclosure is to propose a cardboard support element structure for a cardboard container, the inclusion of which strengthens the cardboard structure and allows the cardboard to be used in applications where the use of another material would be impaired, while at the same time avoiding the impairment of recyclability.

Cardboard container designs can address enhanced mechanical properties by applying separate three-dimensional parts. Such three-dimensional parts can be applied to the lid, for example, by gluing. The gluing can be done before or after lid formation. If the three-dimensional parts are glued to a planar structure such as a blank at the supplier's site, transportation from the supplier's site can be less space-efficient and therefore less cost-efficient, since the three-dimensional nature of the three-dimensional parts prevents stacking. If such gluing is done after transportation from the supplier's site, for example at the production line, gluing the three-dimensional parts on the blank or on the inside of the upright lid during production can complicate the manufacturing operations and slow down the production line speed, correspondingly reducing the productivity of the manufacturing plant. Cardboard lids including support element structures according to the present disclosure have surprisingly been identified as a way to create three-dimensional reinforcing structures that reduce or inhibit adverse effects on transportation efficiency or production line speed at the manufacturing site. Cardboard lids including support element structures according to the present disclosure can be formed using folding machinery that is likely already in place at the manufacturing site, so little or no additional capital is required at the manufacturing site to implement the structures according to the present disclosure. In addition, cardboard lids including the support element structure according to the present disclosure belong to a single blank, thus facilitating the manufacture of such cardboard lids including the support element structure. The cutting of such single blanks can be performed at the supplier's facility before transporting them to a manufacturing facility where the blanks can be erected. In addition, the single blanks can be in the form of flat blanks, which also facilitates transportation and optimizes weight and therefore cost. In addition, the single flat blanks can be partially pre-folded, for example at the supplier's facility, to further optimize transportation efficiency by reducing the 2D (two-dimensional) footprint or reducing the elements of the blank that protrude beyond a given footprint while maintaining the flat nature of the blanks and therefore the stackability of the blanks.

A cardboard lid or blank according to the present disclosure may be made of the same material as that used for a box according to the present disclosure. A blank, lid, box, or container according to the present disclosure may be made from a paper or cardboard material, the paper material being selected from, for example, paperboard, cardboard, a laminate including at least one paperboard or cardboard layer, a cellulose pulp material, or a mixture thereof. The material used to make the blank, lid, box, or container may include other ingredients, for example, colorants, preservatives, plasticizers, UV stabilizers, oxygen, fragrances, recycled materials, moisture barriers, or mixtures thereof. The blank, lid, box, or container may include areas of exterior or interior printing. The blank, lid, box, or container may be made, for example, by cardboard manufacturing. A suitable cardboard blank, lid, box, or container manufacturing process may include, but is not limited to, tube formation from a flat cardboard or paper sheet by a gluing process, folding, or a combination thereof. The cardboard blank, lid, box, or container may be opaque, for example, to protect the contents from external light. In some examples, the blank, lid, box, or container is made at least partially, and in some specific examples, entirely, from a paper-based material. Paper-based material, as used herein, refers to a material that includes paper. Without wishing to be bound by theory, "paper" as used herein refers to a material made from cellulosic pulp. In some examples, the paper-based material includes paper, cardboard, or a mixture thereof, and preferably, cardboard includes paperboard, corrugated cardboard, or a mixture thereof. Corrugated cardboard includes a series of flutes. Each flute can be understood to be a channel. The flutes run parallel to each other, and the direction of the flutes is the direction of progression along each channel. The paper-based material may be a laminate including paper, cardboard, or a mixture thereof, and in some examples, the cardboard includes paperboard, corrugated cardboard, or a mixture thereof, and at least another material. In some examples, at least another material includes a plastic material. In some examples, the plastic material includes polyethylene, polyethylene terephthalate, polypropylene, polyvinyl alcohol, or a mixture thereof. In some examples, the plastic material includes a copolymer of ethane and vinyl alcohol, or EVOH. As the at least another material, a barrier material may be used. The barrier material may be biaxially oriented polypropylene, metallized polyethylene terephthalate, or a mixture thereof. The at least another material may include wax, a cellulosic material, polyvinyl alcohol, silica dioxide, a casein-based material, or a mixture thereof. In some examples, the paper-based laminate includes more than 50% by weight, preferably more than 85% by weight, more preferably more than 95% by weight of a fiber-based material laminate. In some examples, the barrier material may include a plastic material having a thickness of 10 microns to 40 microns. In some examples, the barrier material may include a plastic material having a thickness of 10 microns to 35 microns. The paper-based material may be a laminate. In some examples, the inner surface of the blank, lid, box or container includes paper, cardboard, or a mixture thereof, in certain examples, the cardboard includes paperboard, corrugated board, polyethylene laminate, or a mixture thereof, and in some examples, the outer surface of the blank, lid, box or container, or a combination thereof includes at least another material. Alternatively, the at least another material may also be laminated between two paper-based material layers. Without wishing to be bound by theory, this at least another material can act as a barrier for leaking liquid absorbed by the paper-based material facing the inside of the blank, lid, box, or container, preventing or reducing contaminating flow through the blank, lid, box, or container wall. Other structures may be found to be effective to avoid leakage from the contents or to protect the contents from external fluids, for example from showers, sinks, or handling the container or lid with wet hands. Contamination of the blank, lid, box, or container walls, flaps, or panels can be unsightly for consumers or can contaminate storage areas. Other structures may be found to be effective to prevent the enclosed detergent product from being exposed to external relative humidity. This is particularly important when the enclosed detergent product is inherently moisture sensitive, such as, for example, a water-soluble unit dose detergent article in which the detergent composition is enclosed in a water-soluble film, which is prone to premature rupture when exposed to a higher percentage of external relative humidity. In some embodiments, the blank, lid, box, or container is made of a paper-based material that includes at least another material laminated between two layers of corrugated cardboard. In some embodiments, the material used for the blank, lid, box, or container includes a core cardboard flute material sandwiched between two layers of plain cardboard and a polyethylene laminate. Cardboard boxes, lids, or blanks according to the present disclosure may be made from or include recycled materials or recycled cellulose fibers.

FIG. 1 illustrates an exemplary cardboard lid 100 for a container. The cardboard lid 100 includes side panels 101-104 that form lid sides. In this example, each side panel 101-104 is a rectangular side panel. In this example, four side panels are provided, each forming a respective lid side. In this example, each lid side is connected to two other lid sides by lid corners, each lid corner forming a 90 degree angle. In this example, all lid sides are perpendicular to the same plane. The cardboard lid 100 further includes lid flaps connected to the side panels by lid flap fold lines, two of the lid flaps forming the top panel 105 of the lid, in this example the two lid flaps forming the top panel of the lid are two opposing lid flaps, in this case such two opposing lid flaps forming the top panel are connected to a long side panel, this example includes two long side panels and two short side panels, the short side panels being shorter than the long side panels along a first direction, the first direction according to the present disclosure being a direction perpendicular to the fold lines connecting the side panels to each other. In this example the top panel of the lid is rectangular. In this example the top panel of the lid is perpendicular to each lid side. Exemplary lid flaps forming the top panel are shown in more detail in other figures described herein. It is important to note that the lid flaps are connected to the side panels by lid flap fold lines, as they belong to a single blank, as will be explained in more detail. The flaps should be understood as pieces of cardboard connected to the rest of the lid structure. The flap can be connected to the rest of the lid structure by a fold line, and the lid is made of a one-piece cardboard piece. The flap may be connected to the cardboard structure by a segment, for example a fold line. The flap can also be connected to a portion of the lid by adhesive.

Normal or perpendicular, as used herein, should be understood to mean substantially normal or substantially perpendicular. In some embodiments, normal or perpendicular includes angles less than 120 degrees and greater than 60 degrees. In some embodiments, normal or perpendicular includes angles less than 110 degrees and greater than 70 degrees. In some embodiments, normal or perpendicular includes angles less than 100 degrees and greater than 80 degrees. In some embodiments, normal or perpendicular includes angles less than 95 degrees and greater than 85 degrees.

The cardboard lid 100 further includes a support element structure 106 extending away from the top panel and disposed between the side panels. By extending away from the top panel, it is understood that the support element structure includes at least a portion extending away from the top panel, the support element structure assumes a three-dimensional shape, and the cardboard material of the support element structure defines some boundaries of this three-dimensional shape. In some embodiments, the support element structure includes a portion at least 5 mm away from the top panel. In some embodiments, the support element structure includes a portion at least 10 mm away from the top panel. In some embodiments, the support element structure includes a portion at least 15 mm away from the top panel. In some embodiments, the cardboard structure includes a portion at least 20 mm away from the base plane. In some embodiments, the support element structure includes a portion at least 30 mm away from the top panel. In some embodiments, the support element structure includes a portion at least 35 mm away from the top panel. In some embodiments, the support element structure includes a portion less than 10 cm away from the top panel, for example to avoid a cantilevered condition when the support element structure is functioning in such a manner. In this embodiment, the support element structure 106 has a triangular cross section in a plane perpendicular to the top panel 105. In other embodiments, the support element structure can include a portion of a cylinder or a portion of a prism, such as a triangular, rectangular, or pentagonal prism. Such a prism can be obtained by folding successive portions of the support element structure along parallel lines, and the shape of a portion of a cylinder can be obtained by stretching a single panel of the support element structure. In some embodiments, the support element structure includes an arcuate shape because the support element structure is stretched between other elements, such other elements being part of a lid.

The support element structure according to the present disclosure is intended to provide mechanical support to a cardboard wall, such as the cardboard wall of a container or container lid, which contacts the support element when force or pressure is applied.

The illustrated support element structure 106 corresponds to a portion of a prism, and more specifically, when considering the top panel 105, corresponds to a portion of a triangular prism. In this embodiment, the support element structure includes a linear ridge 107, which corresponds to an edge of the prism, and a first side 108 and a second side 109 of the prism defining the ridge 107, each of which preferably forms an angle of more than 15 degrees (respectively -15 degrees) with respect to the top panel. In this case, the first side 108 of the prism forms an angle of about 30 degrees with respect to the top panel. In some embodiments, the ridge is at least 5 mm away from the top panel. In some embodiments, the ridge is at least 10 mm away from the top panel. In some embodiments, the ridge is at least 15 mm away from the top panel. In some embodiments, the ridge is at least 20 mm away from the top panel. In some embodiments, the ridge is at least 30 mm away from the top panel. In some embodiments, the ridge is at least 35 mm away from the top panel. In some embodiments, the ridge is less than 10 cm away from the top panel, for example to avoid a cantilevered condition when the support element is functioning as such.

It should be understood that features such as number of flaps, flap orientation, number of panels, and angles of the various embodiments described herein can be combined to produce alternative embodiments.

The cardboard lid 100 is such that the lid flap, side panels, and support element structure belong to a single blank.

Having the lid flap, side panel, and support element structures belonging to a single blank can limit the complexity in erecting such a lid, whereby a lid including multiple blanks may require, for example, additional gluing steps or adjustments between the different independent structures.

2A illustrates another exemplary cardboard lid 200 according to the present disclosure. Cardboard lid 200 includes elements 101-109 as described for cardboard lid 100, and such elements are numbered using the same reference numerals. Cardboard lid 200 further includes reinforced lid side 104, which includes reinforced portion 204. Indeed, in some embodiments, at least one of the lid sides, preferably some of the lid sides, and most preferably each of the lid sides includes a reinforcement panel that is connected to the respective side panel by a side panel fold line, such as side panel fold line 214, and the reinforcement panel is folded back onto the respective side panel, and the reinforcement panel belongs to a single blank. In some embodiments, the lid includes two opposing long sides parallel to each other, and two opposing short sides parallel to each other, the long sides being perpendicular to the short sides, and the long sides are reinforced but the short sides are not reinforced, or are thinner than the long sides, or have fewer layers than the long sides, to account for the fact that a user or consumer is more likely to apply pressure to the long sides and that the long sides are more likely to undergo deformation if the midpoint of the long sides along the first direction is further away from the corner of the long side than the midpoint of the short sides is further away from the respective corner of the short side.

The cardboard lid 200 further includes an actuation area 210. Indeed, in some embodiments, at least one side includes an actuation area. In this embodiment, the apex of the support element structure, such as the ridge 107, is aligned with the actuation area 210. Such an actuation area can enable actuation of a lock of a container including a lid according to the present disclosure, as described in further detail in this disclosure. In preferred embodiments, two sides, preferably two opposing sides, more preferably two opposing long sides, include such an actuation area, and in some embodiments, consumers tend to use the span of one hand to actuate both actuation areas simultaneously, and in such instances, the hand span may fit within the length of the short side along the first direction to reach both actuation areas simultaneously.

2B illustrates another exemplary cardboard lid 220 according to the present disclosure. Cardboard lid 220 includes elements 101-109 described for cardboard lid 100 and elements 204, 214, and 210 described for cardboard lid 200, with such elements numbered using the same reference numerals. Cardboard lid 220 further includes a reinforcing panel 213 connected to each side panel 103, and further reinforcing panels, not visible in this view, connected to each side panel 102 and 101. Thus, cardboard lid 220 is such that each of the lid sides includes a reinforcing panel, the reinforcing panel is connected to the respective side panel by a side panel fold line, the reinforcing panel is folded over the respective side panel, and the reinforcing panel belongs to a single blank. The cardboard lid 220 also includes a further or additional activation area 210B, where the apex 107 is aligned with the activation area 210B, where the activation area 210B is a round opening into the side panel 102 opposite the side panel 104 containing the activation area 210, where the activation area 210 also takes the form of a round opening.

Figure 3 illustrates another exemplary cardboard lid 300 according to the present disclosure. Cardboard lid 300 includes elements 101-105 as described for cardboard lid 100, such elements being numbered using the same reference numerals. Lid 300 includes a support element structure 306 according to the present disclosure that is a portion of a cylinder. Support element structure 306 may be formed by a flap 306 connected to side panel 101 by a fold line and sandwiched between top panel 105 and a flap 307 connected to side panel 103 by a fold line, such flap 306 being pulled into an arcuate shape to form the support element structure.

4 illustrates an exemplary cardboard blank 400 for a cardboard lid in accordance with the present disclosure, particularly a cardboard lid similar to exemplary cardboard lid 300. Cardboard blank 400 includes:
- four side panels 104, 101, 102, 103 following one another along a first direction D1, each side panel being connected to at least another side panel by a respective side panel fold line perpendicular to the first direction,
a side flap 401 connected to one of the side panels (in this case the side panel 103) along a fold line perpendicular to the first direction, the side flap 401 following or preceding (in this case following) the four side panels along the first direction;
- three lid flaps 404, 402, 307 following one another along a first direction, each lid flap being connected to a respective regular side panel 104, 102, 103 of the four side panels by a respective lid flap fold line parallel to the first direction, the lid flap fold lines being aligned with one another, the four side panels including a regular side panel and a particular side panel;
- a support element structure, the support element structure including a support element first panel 306 connected to a particular side panel 101 by a particular fold line aligned with the lid flap fold line, the support element structure further including a support element opposing panel 307 included in a lid flap 307 of three lid flaps 404, 402, 307, the lid flap 307 being connected to the opposing side panel 103, the opposing side panel 103 being a regular side panel separated from the particular side panel 101 by a single other regular side panel 102, the support element structure having a total length L2A+L2B along a direction D2 perpendicular to the first direction D1 that exceeds the length L1 of the single other regular side panel 102 along the first direction D1.

It should be understood that numerous other configurations are contemplated. For example, in some cases, flap 401 can be connected to panel 104. A flap such as flap 401 can function to provide a four sided structure ready to stand, for example, by gluing, or to form a flat structure with a reduced footprint, as shown, for example, in FIG. 7B.

It should be understood that in this disclosure, "aligned" may encompass fold lines in the same direction that may be slightly offset from one another, for example, to account for the thickness of the material. In some embodiments, such offset that would be considered to maintain alignment may be less than one-third the thickness of the material forming the blank. In some embodiments, such offset that would be considered to maintain alignment may be less than one-half the thickness of the material forming the blank. In some embodiments, such offset that would be considered to maintain alignment may be less than the thickness of the material forming the blank.

The total length according to the present disclosure is the total length along a direction perpendicular to the first direction of one or more elements forming an upright support element structure, not counting the final portions of such elements configured to be stacked or glued together in such upright support element, in particular the total length along said direction perpendicular to the first direction of elements connected to a particular side panel 101 and an opposing side panel 103 and extending beyond the respective side panels along said direction. Such total length can correspond to the perimeter of the upright support element structure, for example, along a cross section of the upright support element structure along a plane parallel to the upright single other ordinary side panel while following the support element structure, running from corner to corner of the upright lid and passing through the apex of the support element structure. The fact that such total length exceeds the length of the single other ordinary side panel along the first direction reflects the fact that the support element structure extends away from the top panel, and thus the perimeter along the first direction from one end of the top panel to the opposite end of the top panel exceeds the length of the top panel itself along this same direction. For example, in the case of the lid 300, the length along the cylindrical portion corresponding to the curved line actually exceeds the length of the segment between the points of the cylindrical portion intersecting with the top panel. Similarly, in the case of the lids 100, 200 or 220, the length along the triangular portion of the support element structure exceeds the length of the segment separating the points of the triangular structure intersecting with the top panel. Thus, the fact that the support element structure extends away from the top panel of the upright lid corresponds to the fact that in the blank, the total length exceeds the length of a single other normal side panel. It should be understood that such total length corresponds to the total length of the elements in the blank of the various elements forming the support element, which is not exactly the same as the length of the upright support element in the upright lid. It should also be noted that some of the various elements forming the support element may be configured to be fully or partially bonded to each other when forming the upright support element. In this case, the length of such a whole or part of the portion configured to be bonded to form a double layer structure may not contribute twice to such total length. In some embodiments, all elements in the blank that are connected to and extend beyond a particular side panel have a particular total length along a direction perpendicular to the first direction that exceeds the length of a single other regular side panel along the first direction, thereby ensuring that the total length exceeds the length of a single other regular side panel along the first direction and includes the particular total length. In other words, even if the support element opposing side panel 307 of length L2B were fully bonded to the support element first panel 306 of length L2A to make the support element stand upright, the support element would stand upright because L2A, which in this case corresponds exactly to the perimeter of the upright support element structure, is longer than L1.

5 illustrates an exemplary cardboard blank 500 for a cardboard lid in accordance with the present disclosure, particularly a cardboard lid similar to exemplary cardboard lid 220. Cardboard blank 500 includes the following elements, some of which correspond to corresponding elements of cardboard blank 400 and therefore share the same reference numbers:
- four side panels 102, 103, 104, 101 following one another along a first direction D1, each side panel being connected to at least another side panel by a respective side panel fold line perpendicular to the first direction,
a side flap 401 connected to one of the side panels (in this case side panel 101) along a fold line perpendicular to the first direction, the side flap 401 following or preceding (in this case following) the four side panels along the first direction (in another example such a side flap 401 may precede side panel 102);
- three lid flaps 402, 507, 404 following one another along a first direction, each lid flap being connected to a respective normal side panel 102, 103, 104 of the four side panels by a respective lid flap fold line parallel to the first direction, the lid flap fold lines being aligned with one another, the four side panels including a normal side panel and a particular side panel;
- a support element structure, the support element structure comprising a support element first panel 506 connected to a particular side panel 101 by a particular fold line aligned with the lid flap fold line and an additional fold line parallel to the particular fold line, the support element structure further comprising a support element opposing panel 507 included in a lid flap of the three lid flaps and connected to an opposing side panel 103, the opposing side panel 103 being a normal side panel separated from the particular side panel 101 by a single other normal side panel 104, the support element structure having a total length along a direction D2 perpendicular to the first direction D1 (which in this case corresponds exactly to the perimeter L2C+L2D-L2D2 of the upright support element structure as described below) that exceeds the length L1 of the single other normal side panel 104 along the first direction D1.

The cardboard blank 500 further includes a first wing 510 adjacent to the support element first panel 506 and connected to the support element first panel 506 by a first wing fold line perpendicular to the first direction.

The exemplary wings, such as the first wing 501, can contribute to the support element structure, for example, acting as a centering patch on the lid to properly position and align the lid with the corresponding container, thereby guiding the lid during closure of the container. The exemplary wings, such as the first wing 501, can also contribute to increasing manufacturing tolerances by compensating for some degree of misalignment. The exemplary wings, such as the first wing 501, can also contribute to improving the consumer experience by facilitating closure of the container.

Such a first wing may be included in different exemplary blanks according to the present disclosure to obtain different exemplary lids according to the present disclosure, whereby the support element structure of such lids includes a support element first panel and a first wing, the first wing adjacent to the support element first panel and separated from the support element first panel by a first wing fold line, the first wing including a first wing end distal to the first wing fold line, the first wing end contacting the top panel to maintain the support element first panel extending away from the top panel. When folded in place from the blank, such a first wing folds parallel to the lid side (parallel to the lid side 104 in the example of blank 500) with a distal end (e.g., distal end 511) contacting the top panel 105 (e.g., formed from flaps 402 and 404) to push the support element first panel (e.g., 506) away from such top panel to achieve an exemplary lid according to the present disclosure. In some embodiments, the distal end may be curved to facilitate sliding the first wing relative to the top panel when erecting the lid. In other embodiments, the distal end may be straight, for example to facilitate cutting the blank.

The cardboard blank 500 includes a second wing 520 adjacent to the support element first panel and perpendicular to the first direction and connected to the support element first panel by a second wing fold line on the side of the support element first panel opposite the first wing 510. Note that while the exemplary blank 500 includes both a first wing and a second wing, another exemplary blank not shown here may include a single wing.

Such a first wing may be included in different exemplary blanks according to the present disclosure to obtain different exemplary lids according to the present disclosure, whereby the support element structure of such lids includes a second wing adjacent to the support element first panel and separated therefrom by a second wing fold line, the second wing including a second wing end distal to the second wing fold line, the second wing end contacting the top panel to maintain the support element first panel extending away from the top panel, and the second wing fold line and the first wing fold line on opposite sides of the support element first panel.

In this exemplary blank 500, the first and second wing ends are rounded to facilitate uprighting of the lid. In this embodiment, the shape of the second wing mirrors the shape of the first wing along a direction D2 perpendicular to the first direction D1 to provide a balanced extension of the support element structure.

In the exemplary blank 500, the first wing 510 corresponds to a cutout in one of the three lid flaps adjacent the support element first panel, specifically in this case the cutout in flap 404. In this exemplary blank 500, the second wing 520 corresponds to a cutout in one of the three lid flaps adjacent the support element first panel, specifically in this case the cutout in flap 402. In some other embodiments, such a cutout may correspond to a single wing.

In the exemplary blank 500, the support element structure includes a connecting panel 508 between the support element first panel 506 and a particular side panel 101. Such connecting panel, in this example, is directly connected to the particular panel by a particular fold line and also directly connected to the support element first panel by an additional fold line parallel to the particular fold line. Direct connection should be understood in the sense that a single fold line forms such a connection. When the blank is erected to form the lid, the connecting panel may remain substantially parallel to the top panel, with the support element first panel extending away from the top panel.

In the exemplary blank 500, the support element structure includes an opposing connection panel 509 between the support element opposing panel 507 and the opposing side panel 103. Such a structure can, for example, enable the support element first panel 506 to be held in place when the lid is erected from the blank. In this embodiment, the opposing panel 507 can coincide with an additional panel 530 when the blank is erected into a lid, such additional panel 530 being directly connected to the support element first panel on the opposite side of the connection panel 508. Such a relationship is described in more detail in the exemplary manufacturing method. Note that in some embodiments, the connection panel 508 and the opposing connection panel 509 have substantially the same length along the direction D2 to position the support element in a central position, so that the top of the support element can be positioned in alignment with the opening for the working area, which can be located at the midpoint along the direction D1 of the corresponding side panel. Similarly, the desired positioning of the apex can be obtained by appropriately modifying the respective lengths of the panels 508 and 509.

In this exemplary blank 500, as described in the context of blank 400, it should be understood that the total length corresponds to the total length of the various elements forming the support element in the blank, which is not exactly the same as the length of the upright support element of the upright lid. It should also be noted that some of the various elements forming the support element may be configured to be fully or partially glued together when forming the upright support element. In this case, the length of such a whole or part configured to be glued to form a double layer structure may not contribute double to such total length. In some examples, all elements in the blank that are connected to and extend beyond a particular side panel ensure that the particular total length along a direction perpendicular to the first direction exceeds the length of a single other regular side panel along the first direction, thereby ensuring that the total length exceeds the length of a single other regular side panel along the first direction, and that the total length includes the particular total length. In other words, even if the support element facing side panel 507 is glued to the additional panel 530 to make the support element stand upright, the length obtained by subtracting the length L2D2 of the glued portion between 507 and 530 along D2 from L2D+L2C is longer than L1, so the support element will stand upright.

The exemplary blank 500 further includes four reinforcing flaps 540, each reinforcing flap connected to a respective side panel by a respective reinforcing flap fold line, the reinforcing flap fold lines being aligned with one another and parallel to the first direction, the reinforcing flap being located on a side of the side panel opposite the lid flap and the support element structure. In this figure, for ease of illustration, the reinforcing flaps are shown folded over their respective side panels. It should be noted that blanks having a folded flap-like configuration can be used to facilitate transportation of the blank, to reduce the size of the blank while keeping it substantially flat. Such reinforcing flaps can be glued to their respective side panels. Such reinforcing flaps can reinforce their respective side panels, thereby reinforcing the overall structure.

In the exemplary blank 500, the particular side panel 101 and the opposing side panel 103 are short side panels having the same panel length along a first direction, which is shorter than the panel length of the other two side panels 102, 104 along the first direction, which are long side panels having the same length L1 along the first direction. In some embodiments, the length of the short panel is less than 80% of the length of the long panel along the first direction. In some embodiments, the length of the short panel is less than 70% of the length of the long panel along the first direction. In some embodiments, the length of the short panel is less than 60% of the length of the long panel along the first direction. In some embodiments, the length of the short panel is less than 50% of the length of the long panel along the first direction. In some embodiments, the length of the short panel is more than 10% of the length of the long panel along the first direction. In some embodiments, the length of the short panel is more than 20% of the length of the long panel along the first direction. In some embodiments, the length of the short panel is more than 30% of the length of the long panel along the first direction. Using relatively short lengths for the short panels supporting the support element structure can make such support element structures relatively more resilient in that the cantilever beam is reduced. In some embodiments, the length of the short panels preferably accommodates the hand span of the consumer, and the interior volume or cavity of the corresponding container is set by setting the length of the long panels to reach a desired capacity or fill level at a given container height.

In the exemplary blank 500, each long side panel includes a respective opening for an operating area, each respective opening being preferably a through opening intersecting a flute included in the long side panel. Such a configuration not only allows for the provision of an operating area, but also allows for the provision of an operating area in conjunction with the positioning of the support elements, allowing for ventilation of the long side panels through such intersecting flutes, which would otherwise be weakened in a humid environment due to their increased length and reduced resilience compared to the short panels. Such relative positioning of the openings, support elements, short panels and long panels all cooperate to contribute to a stronger cardboard structure.

Blanks according to the present disclosure can be conveniently transported as a stack of multiple flat or substantially flat blanks. In some embodiments, the blanks in the stack include reinforcing flaps that are folded over, and preferably glued, to reduce the 2D footprint of the blanks, resulting in blanks that are not perfectly flat, but are still stackable. Such stacks facilitate erection of corresponding lids at a manufacturing facility separate from the facility that produces the blanks.

6 shows an exemplary consumer product 600 including a detergent product (not visible in FIG. 6) and a container, which includes a box 601 and a lid that corresponds to lid 220 in this example, although other lids according to the present disclosure are contemplated. Box 601 includes a lock 610 for maintaining the lid in a closed position, the lock including an actuator that aligns with a portion of a support element structure that fits within the box when the lid is in the closed position. Lock 610 cooperates with actuation area 210B. An additional lock can be provided that cooperates with opening 210, such additional lock being on the rear of the box, mirroring lock 610 located on the front of the box.

Detergent products are relatively heavy products, for example when a container for such a product carries the entire weight of such a detergent product, especially when the consumer product has been recently acquired and thus holds a significant amount of detergent product. Some consumers may carry such a consumer product by holding the base of the box in which such a detergent product is contained, but such carrying may also occur by holding the lid of such a consumer product, rather than holding the base. In such a case, the lid may come off under the gravity of the detergent product, opening the box, which may fall and scatter its contents. Such a situation should be avoided. Besides avoiding such unintentional unlocking of the lid, the structure of the consumer product container should preserve or improve opening ergonomics and prevent or reduce permanent sidewall deformation under excessive or repeated application of force applied to the consumer product, for example during transport, in contact with other objects in a grocery store shopping bag, under external pressure, or when dropped. At the same time, the container may be elaborated to preserve the environment. The consumer product according to the present disclosure aims to take these different aspects into account.

A consumer product should be understood in this disclosure as, inter alia, a product that is provided to an end consumer. Such consumer products can be purchased, for example, in a supermarket, and the end consumer can store such consumer products in their home. Since consumer products may be provided in large quantities, they should be designed with environmental concerns in mind. Consumer products should also be designed with transportation to a retail store in mind. Consumer products should also be designed with shelf storage in a retail store in mind. Consumer products should also be designed with transportation from a retail store to a consumer's home in mind. Consumer products should also be designed with storage in an individual end consumer's home in mind. Consumer products should also be designed with use of the consumer product in an individual end consumer's home in mind. Consumer products should also be designed with disposal in mind.

Consumer products according to the present disclosure include detergent products. Detergent products, in this disclosure, should be understood as products that include a surfactant. Detergent products may also include bleach or other ingredients. Exemplary detergent product compositions are described in more detail herein.

Examples of unit dose detergent pouches are described in more detail herein.

The consumer product according to the present disclosure further includes a container. A container should be understood in this disclosure as an object that contains contents within a cavity of the container, for example. The container facilitates protection, transportation, storage, access, and disposal of the consumer product. In this disclosure, the container includes a box. A box should be understood as a three-dimensional object that is approximately parallelepiped, barrel-shaped, cylindrical, circular, elliptical, or cubic, defining a cavity. The use of a parallelepiped box can facilitate storage and transportation by allowing the boxes to be stacked in a space-efficient manner. In some embodiments, the box may be a parallelepiped with some rounded, tapered trapezoidal, or chamfered edges. The box according to the present disclosure includes a detergent product. It should be understood that the detergent product is contained or stored in the box. The box according to the present disclosure can include a base, a sidewall, and an opening. The base according to the present disclosure should be understood as a surface against which the box can bear when the box is placed on a supporting surface, such as a shelf or floor. In some embodiments, the base is flat. In some embodiments, the base is rectangular. In some embodiments, the base is elliptical or circular. In some embodiments, the base is flat. In some embodiments, the base has an embossed shape that is raised in relief. The sidewalls according to the present disclosure should be understood as extending from the base and connecting the base to the opening, to a transition piece or a lid. It should be understood that the connection between the base and the opening may include a transition piece in addition to the sidewall. For example, the transition piece may be glued or otherwise attached to the sidewall. In some embodiments, the sidewalls are perpendicular to the base. In some embodiments, the base is rectangular and has four sidewalls that extend perpendicularly from the base, each sidewall being rectangular and each sidewall being connected to a side of the base by a sidewall side and to two other sidewalls of the four sidewalls by two other sidewalls. In some embodiments, the base is elliptical or circular and the sidewalls form a generally cylindrical wall that extends from the base in a direction normal or perpendicular to the base. In some embodiments, the sidewall has a shape corresponding to one of a square, a rectangle, a trapezoid, a cross section of a sphere, a cross section of an oval, or a cross section of an ellipsoid. An opening according to the present disclosure should be understood as an opening that provides access to the detergent product contained in the box. In some embodiments, the opening faces the base. In some embodiments, the opening has a surface that is smaller than the surface of the base. In some embodiments, the opening has a surface that is larger than the surface of the base to provide improved access, for example, using a sidewall that extends from the base at an angle of more than 90 degrees from the base. In some embodiments, the opening is provided after removal of a tamper-evident mechanism, including, for example, a perforated strip that is removed upon first use, or a tamper-evident sticker that locks the lid to the box or tray. In some embodiments, the opening is located on a top panel of the box, the top panel of the box faces the base of the box, the top panel of the box is separated from the base of the box by at least a sidewall, the top panel of the box is generally flush with the base of the box, the opening occupies a portion of the top panel, the top panel includes a peripheral portion that surrounds the opening, and the peripheral portion includes, for example, a transition portion between the sidewall and the opening. In some embodiments, the opening is rectangular. In some embodiments, the opening is rectangular with rounded edges. In some embodiments, the opening is circular or elliptical. A lid according to the present disclosure should be understood as an element that allows the opening of the container to be repeatedly closed or opened. In some embodiments, the lid may be connected to the box, for example by a hinge, or may be separate from the box. A lid according to the present disclosure may include a top and sides or lid sides. It should be understood that the top of the lid is intended to cover the opening of the box when the lid is in the closed position. In some embodiments, the top of the lid is rectangular. In some embodiments, the top of the lid is circular, hexagonal, octagonal, or elliptical, and structures such as circular or elliptical are approximated, for example, by multiplying the number of side panels and lid flaps. In some embodiments, the lid includes chamfered edges. In some embodiments, the top of the lid is rectangular with rounded edges. Although named "top", it should be understood that the top of the lid may be oriented in different ways. The lid may include sides. It should be understood that the sides according to the present disclosure are elements that are connected to the top of the lid and extend from the lid to engage one or more side walls of the box. The sides are responsible for positioning the top of the lid over the opening. In some embodiments, the sides extend vertically from the top of the lid. In some embodiments, the sides surround the entire perimeter of the top of the lid. In some embodiments, the sides surround the entire perimeter of the top of the lid partially, and some of the top of the lid is free of sides. The top of the lid can cover the opening, at least a portion of the sides can cover at least a certain portion of the side walls when the lid is in a closed position, and the lid is movable from a closed position to an open position. The movement of the lid may be constrained by a connection to the box, such as a hinge, or may be completely removable, for example, to provide improved access to the contents of the box. The box and lid cooperate to act as a container for storing, transporting, and facilitating access to the contents of the container.

The container according to the present disclosure includes a lock. A lock should be understood in this disclosure as a mechanism that prevents or reduces the possibility of accidental opening. The lock according to the present disclosure is for maintaining the lid in a closed position. It should be understood that the lock according to the present disclosure is expected to function under normal use of the container. For example, it should be understood that the lock may not fulfill its function if the box is used in an abnormal state or if the box is in an abnormal state. According to the present disclosure, the lock includes an actuator that can be moved from a locked position to an open position by applying an actuation pressure to the actuator when the lid is in a closed position. The actuator should be understood in this disclosure as a mechanical structure that is subjected to a movement upon actuation by an external force or an actuation pressure, such movement resulting in the opening of the lock when such movement is performed. In some embodiments, the actuator according to the present disclosure is elastic and has a default position, such default position corresponds to the lid remaining closed, and the elasticity is countered by the external force or the actuation pressure to open the lid. In some embodiments, the actuator includes a flexible element that has a default position corresponding to the lid remaining closed and is elastic in that the flexible element is pressed to open the lid and the flexible element springs back to the default position when the pressure is released. It should be understood that the pressure is generated by applying a force to a surface. The actuator according to the present disclosure has at least two positions, an open position and a locked position, whereby the open position corresponds to a position that allows the lid to be opened and the locked position prevents the lid from being opened or reduces the possibility of accidental opening of the lid.

The actuator according to the present disclosure may be connected to a specific portion of the side wall of the box, which may be a specific portion that is covered by at least a portion of the side when the lid is in the closed position, the actuator abuts against a locking tab on the side when in the locked position, the actuator is maintained away from the locking tab when in the open position, and the actuator is displaceable by an actuation pressure by an unlocking displacement distance in a direction perpendicular to the specific portion of the side wall. The connection of the actuator to the specific portion of the side wall results from the actuator's involvement in locking or unlocking the specific portion of the side wall from the portion of the side that covers the specific portion of the side wall, thereby allowing the lid to be released from the box. The side may include a locking tab. The locking tab should be understood as a mechanical element that interfaces with the actuator. In some embodiments, the locking tab may be in the form of a bulge, ridge, embossment, or additional layer of material that extends away from the side and protrudes from the side of the lid towards the specific portion of the side wall when in the locked position so that the actuator can abut against the tab when in the locked position to prevent the specific portion of the side wall from separating from the side in the area of the actuator. In some embodiments, the locking tab is included in the side itself, for example formed by an opening in the side. Abutment according to the present disclosure should be understood as contact between the actuator or a part of the actuator and the tab, such contact preventing the opening of the lid. The actuator is maintained away from the locking tab when in the open position in order to release the locking tab. Such release of the locking tab allows the lid to open. The displacement or movement of the actuator from the locked position to the open position is by applying (directly or indirectly) an actuation pressure or force to the actuator such that the actuator is displaced in a direction perpendicular to a particular portion of the sidewall a distance sufficient to inhibit the actuator from contacting the locking tab, for example a distance corresponding to the displacement distance. It should be understood that the force or pressure leading to the displacement can have several different directions, and such different directions contribute to the displacement if a component of such force or pressure is in a direction perpendicular to a particular portion of the sidewall. Such force or pressure may also include a component that may be parallel to the sidewall. However, the actuation is caused by a component of such force or pressure that is perpendicular to the portion of the sidewall. The presence of such a component perpendicular to a portion of the sidewall is responsible for the locking role, which avoids accidental opening by lifting the container by applying a force parallel to the sidewall to lift the lid, but the desired opening occurs by the consumer "pushing" the actuator and applying an unlocking force or pressure that allows the lid to open. In other words, the consumer can apply a force to the actuator along a direction that may not be perpendicular to the sidewall, but if a component of such force is perpendicular to the sidewall, such a component may be responsible for the application of pressure that leads to displacement.

Such a lock is involved in preventing or reducing the risk of accidental opening of the lid while allowing the desired opening by the consumer, and the function of such a lock relies on ensuring that the actuator remains in abutment against the locking tab even when the lid is pulled hard in a direction parallel to the side wall to transport or lift the consumer product. The avoidance or reduction of the risk of accidental opening also applies to forces applied in a direction parallel to the side wall, for example by friction with another box placed alongside the box according to the present disclosure, or by the box tipping over during transport, or by internal movement of the contents of the box pushing against the lid during transport. However, a strong pull in a direction parallel to the side wall may affect the structure of the side wall, for example resulting in bending of the side wall, which may result in an undesired disengagement of the locking tab from the actuator due to the fact that the actuator is connected to a certain part of the side wall. This will result in an undesired opening of the lid. If the side wall is made of a material such as cardboard used to form the side wall, the possibility of such undesired opening of the lid may be higher, especially if the box is a cardboard box.

In some embodiments, the lock is located in a central region of the sidewall of the box. The central region should be understood to be substantially equidistant from both edges of the sidewall concerned, such edges being along a direction perpendicular to the base of the box. In such an example, it should be understood that the lock is located closer to the edge of the sidewall closer to the opening than the edge of the sidewall closer to the base, while still being in the central region relative to the edge perpendicular to the base. Such a central location of the lock can be responsible for preventing the lid from sliding off the box when the box is lifted by applying pressure to the actuator to hold the lid, such pressure pressing the actuator centrally against the support element structure, thereby balancing the forces maintaining the connection between the lid and the box and preventing accidental opening. In some embodiments, the lock may be located on the sidewall and between two edges of the sidewall, such edges being perpendicular to the base, and the lock is located closer to one edge than the other edge of the two edges, for example, 1/3 of the distance between the two edges. In some embodiments, one side wall may include two locks. In some embodiments, the two locks may be offset relative to each other with respect to the centerline to increase the distance separating the two locks. In some embodiments, more than two locks may be provided. In some embodiments, three locks may be provided, for example, corresponding to a first lock for the thumb of a user's hand and two other locks on the other side of the lid for the index and middle fingers of the same user's hand, such that such a user may simultaneously operate three locks with one hand.

The present disclosure aims to resolve this apparent conflict between, on the one hand, using a material for the sidewall that is resistant to accidental opening, and, on the other hand, using a material for the sidewall that is particularly environmentally friendly.

The container may be made from a rigid cardboard material, a flexible cardboard material, or a mixture thereof. In some examples, the material forming the box or lid has a wall thickness greater than 220 microns and less than 3 mm. In some examples, the material forming the box or lid has a wall thickness greater than 1 mm and less than 2 mm. In some examples, the material forming the box or lid is folded on itself, for example, to reinforce part or all of the box or lid. The container can be made from a paper material, a bio-based material, bamboo fiber, cellulose fiber, a cellulosic or fiber-based material, or a mixture thereof. The container can be made from a material including recycled materials, for example recycled cellulose fiber-based materials.

The lid according to the present disclosure actually includes a support element structure, which enters the opening when the lid is in the closed position, at least a portion of the specific portion of the sidewall is located between the side and the support element structure when the lid is in the closed position, a clearance distance separates the sidewall from the support element structure in a direction perpendicular to the specific portion of the sidewall when the lid is in the closed position and no actuation pressure is applied, and the clearance distance is reduced to zero by the specific portion of the sidewall bending when the lid is in the closed position and actuation pressure is applied above a pressure threshold. Both the support element structure and the side are structurally part of the lid, and the support element structure and the side allow the specific portion of the sidewall to be pinched, thereby causing the specific portion of the sidewall to sink and prevent undesired disengagement of the actuator from the locking tab. It is important to note that when actuation pressure is applied while lifting the box through the lid, the applied pressure brings the pinched specific portion of the sidewall into contact with the support element structure, thereby compensating for gravity that would otherwise separate the lid from the box, and such compensation for gravity is due to the resistive static frictional forces between the specific portion of the sidewall and the support element structure. In some embodiments, the use of the support element structure allows the use of relatively flexible materials to make the box, which in the absence of the support element structure would bend to a point that the box would fall if lifted by its lid. Allowing the use of relatively flexible materials also allows the use of less of such materials, due to the presence of the support element structure compensating for such flexibility. The presence of such support element structures prevents or reduces the risk of accidental opening, even when actuation pressure is applied to the lock's actuator, for example, when lifting the box while applying pressure to the lock's actuator.

The support element structure enters the opening when the lid is in the closed position and fits into the box when the lid is in the closed position. Such entry into the opening should be understood in the sense that the support element structure includes a part of the support element structure that enters the opening when the lid is moved from the open position to the closed position, and such a part of the support element structure exits the opening when the lid is moved from the closed position to the open position. At least a part of the specific part of the side wall is located between the side surface and the support element structure when the lid is in the closed position. This structure makes it possible to capture the specific part of the side wall between the side surface and the support element structure, the specific part of the side wall being inserted between the side surface and the support element structure when the lid is moved from the open position to the closed position, and the specific part of the side wall being released from between the side surface and the support element structure when the lid is moved from the closed position to the open position. The clearance distance separates the side wall from the support element structure in a direction perpendicular to the specific part of the side wall when the lid is in the closed position and no operating pressure is applied, such a direction corresponding, for example, to the direction of the linear ridge. Such clearance distance is present on a first side of the support element structure and is repeated on a second side of the support element structure. Such clearance distance allows the support element structure to be inserted through the opening when the lid is closed such that the support element structure does not collide with a particular portion of the side wall when the lid is closed. When an actuation pressure is applied above a pressure threshold when the lid is in the closed position, the clearance is reduced to zero by bending a particular portion of the side wall. When such pressure threshold is reached, the side wall leans against the support element structure through a clearance distance that is reduced to zero, thereby preventing the side wall from distorting too much and from sinking to the point where the actuator releases the locking tab. The clearance distance according to the present disclosure is in some embodiments related to a tolerance distance between the lid and the box, which together allow the lid to be placed on the box without undue difficulty while avoiding the lid coming loose when in the closed position. Although the clearance distance according to the present disclosure is taken into account in the area of the lock, the tolerance distance between the lid and the box may be taken into account along the entire circumference of the opening of the box. In some embodiments, the tolerance is at least 0.1 mm and less than 5 mm. In some embodiments, the tolerance is at least 1 mm and less than 3 mm. It should be understood that such tolerances are measured, for example, when the lid is in a closed position, between the inner surface of the side and the outer surface of the sidewall, and that such tolerances may have different values in the area of the lock.

In some embodiments, when the lid is in the closed position and no actuation pressure is applied, the clearance distance is at least 1 mm and less than 1 cm. Such a range allows for both easy closure of the lid and preventing subsidence of certain portions of the sidewall that could lead to undesired unlocking. In some embodiments, when the lid is in the closed position and no actuation pressure is applied, the clearance distance is at least 1.5 mm and less than 0.5 cm. In some embodiments, when the lid is in the closed position and no actuation pressure is applied, the clearance distance is at least 2 mm and less than 0.4 cm.

In some embodiments, as shown, for example, in FIG. 6, the actuator includes a flap 603 connected to a particular portion of a sidewall of the box by a hinge portion, the flap extending from the hinge portion to a distal edge of the flap, the hinge portion being between the side surface and the support element structure when the lid is in the closed position, the distal edge extending away from the particular portion of the sidewall, the distal edge of the flap abutting a locking tab on the side surface when in the locked position, the flap being flush with the particular portion of the sidewall, the distal edge being maintained away from the locking tab when in the open position, and an actuation pressure displaces the flap from the closed position to the open position by an acute actuation angle, the acute angle corresponding to displacing the distal edge by an unlocking displacement distance. In some embodiments, the acute angle is between 5 and 60 degrees. In some embodiments, the acute angle is between 5 and 45 degrees. In some embodiments, the acute angle is between 5 and 20 degrees. In some embodiments, the acute angle is a function of the length of the locking flap in a direction generally parallel to the particular section, and the thickness of the locking tab, as well as the tolerance between the side wall of the box and the side of the lid, and the tolerance between the side wall of the box and the flap, or the patch disclosed below. In some embodiments, the horizontal displacement measured at the end of the locking flap that abuts the locking tab (along a direction substantially perpendicular to the side wall that includes the particular section) is at least the thickness of the locking tab along a direction substantially perpendicular to the side wall that includes the particular section. In some embodiments, such horizontal displacement is included between 0.3 mm and 30 mm. In some embodiments, the length of the flap has a length along a direction generally perpendicular to the base of the box that is greater than the sum of different tolerances including the play between the locking tab and the flap in the abutment area when the lid is in the closed position and the container is not under external pressure, the tolerance between the side of the lid and the side wall of the box, and the tolerance between the side wall of the box and the flap, as well as the bending deformation of the flap. In some embodiments, the locking flap has a length along a direction generally perpendicular to the base of the box that is at least 3 mm and less than 60 mm. In some embodiments, the locking flap has a length of at least 15 mm and less than 45 mm along a direction generally perpendicular to the base of the box. In some embodiments, the locking flap has a length of at least 25 mm and less than 35 mm along a direction generally perpendicular to the base of the box. In some embodiments, the flap has a width of 5 mm to 60 mm along a direction perpendicular to its length and parallel to the particular portion. Such exemplary width dimensions may allow for facilitating disengagement of the lock by limiting its width while avoiding the risk of the lock being distorted by pressure by providing a sufficient width for the lock. Such sizing choices may depend on the materials selected for the different parts forming the container. Such flaps may be used in different examples or configurations than those shown in FIG. 6.

In some embodiments, not shown here, the actuator includes a patch that is adhered to a particular portion of the sidewall. Such a patch may be, for example, a piece of material of the same nature as the material used to make the box or the lid, such piece of material being adhered to the box, for example, such that the piece of material is structurally separated from the box, such that the piece of material interacts with the locking tab, such that the piece of material includes, for example, a fold line that defines a first portion that interacts with the locking tab and a second portion that is adhered to the box, thereby functioning as a flap as described herein.

In some embodiments, such as shown in FIG. 6, the support element structure 200 includes a support area that, when an actuation pressure is applied above a pressure threshold when the lid is in the closed position, contacts a specific portion of the sidewall when the clearance is reduced to zero by bending the specific portion of the sidewall, such that the contact area faces the actuator 603 along a direction perpendicular to the specific portion of the sidewall. Introducing such a contact area at the level of the actuator makes it possible to improve the elasticity of the structure, such that the clearance distance separating the sidewall from the support element structure is reduced to zero and the actuation pressure is directly absorbed by the support element structure when the actuator is in direct contact with the support element structure at the contact area.

The exemplary consumer product 600 includes a lock 610, as shown in FIG. 6. The consumer product 600 also includes an additional lock (not shown). Indeed, in this embodiment and some other embodiments, the consumer product includes an additional lock, where the additional lock includes an additional actuator connected to an additional specific portion of the side wall, where the specific portion of the side wall is included in a first side wall of the box, and where the additional specific portion of the side wall is included in a second side wall of the box, where the first side wall is opposite the second side wall. The consumer product 600 includes an actuator 603 of the lock 610 and an additional actuator of the lock. It should be understood that in this embodiment and some other embodiments including an additional lock, such an additional lock can have a similar or different structure to a lock according to the present disclosure. In some embodiments, the additional lock has a structure corresponding to the structure of a lock according to the present disclosure. In some embodiments, the additional lock has a different structure from the structure of a lock according to the present disclosure. In some embodiments, the additional lock according to the present disclosure is provided on the same side wall as the lock according to the present disclosure. In some embodiments, the additional lock is provided on a side wall adjacent to the side wall including the lock.

In the embodiment shown in FIG. 6, the side of the lid includes an actuation area 210B and an additional actuation area 210. Indeed, in this embodiment and some other embodiments, the side of the lid includes an actuation area facing the actuator, allowing the actuator to be displaced from the closed position to the open position by applying an actuation pressure to the actuation area when the lid is in the closed position. The actuation area includes one or more of an actuation opening, an actuation flap, an actuation slit, or an actuation membrane, and the actuation area further includes a visual indicator indicating the location of the actuation area. In the embodiment shown in FIG. 5 and FIG. 6, the actuation areas 210B and 210 each include an actuation opening. The visual indication may be printed on the exterior surface of the side and may include one or more arrows or one or more areas printed in a prominent color or specific text that provide an instruction such as "press here to open," or any combination of such instructions.

In the embodiment shown in FIG. 6 and in some other embodiments not shown here, the side includes an additional actuation area 210 facing the additional actuator and enabling the displacement of the additional actuator, the actuation area 210B and the additional actuation area 210 being separated by a circumferential path along the outer surface of the lid, the circumferential path being less than 20 cm and more than 9 cm. In some embodiments, this circumferential path is the shortest circumferential path between the top of the actuation area and the top of the additional actuation area, such top being the point of the respective actuation area or the additional actuation area closest to the top of the lid. In some embodiments, the circumferential path is less than 15 cm and more than 11 cm. In some embodiments, the circumferential path is less than 14 cm and more than 12 cm. Such a circumferential path length can advantageously allow an adult user to simultaneously place the thumb of one hand on the actuator and the index finger (or middle finger) of the same hand on the additional actuator in order to simultaneously press both the actuator additional part and the additional actuator with one hand to unlock and open the lid. In other embodiments, the two locks may be provided on the same side wall, and opening is achieved by actuating both locks, for example using both thumbs.

In the exemplary consumer product 600, the actuation areas 210B and 210 are linearly separated from the exterior surface of the respective side on which they are located by a distance greater than 6 cm and less than 12 cm. In some embodiments, the distance is about 8 cm. In some embodiments, the distance is greater than 7.5 cm and less than 8.5 cm. In some embodiments, the distance is greater than 8.4 cm and less than 10.4 cm. In some embodiments, the distance is greater than 8.9 cm and less than 9.9 cm. In some embodiments, the distance is about 9.4 cm. In some embodiments, the clearance distances separating the side walls from the support element structure are between 1 mm and 4 mm, respectively, when no actuation pressure is applied. In some embodiments, the clearance distances are between 3 mm and 4 mm, respectively, when no actuation pressure is applied.

In the embodiment shown in FIG. 6, each lock is separated from the respective gable of the support element structure by a clearance distance. In this embodiment and some other embodiments according to the present disclosure, the support element structure includes a resilient structure that simultaneously contacts both the specific portion of the first side wall and the additional specific portion of the second side wall when the lid is in the closed position and both the actuator and the additional actuator are subjected to an actuation pressure above a pressure threshold, such that both the specific portion of the first side wall and the additional specific portion of the second side wall flex. In such a configuration, the resilient structure of the actuator absorbs any excess pressure applied to the actuator to open the lid. In some embodiments, the resilient structure, or cardboard structure, is one piece, e.g., for ease of manufacture. One piece should be understood to be made from a one piece piece of material. In some embodiments, the resilient structure includes a multiple part structure, e.g., for ease of assembly.

In some embodiments, the side of the lid covers about 30% of the side wall of the box, where 30% corresponds to the ratio between the height of the side in a direction perpendicular to both the top of the lid and the base of the box on the one hand, and the height of the side wall in a direction perpendicular to both the top of the lid and the base of the box on the other hand. In one embodiment, the side completely surrounds the side wall around the opening. Such coverage of the side is responsible for ensuring the placement of the lid, structural resilience, and protection of the contents. In some embodiments, the side covers at least 30% of the side wall when the lid is in the closed position. In some embodiments, the side covers at least 35% of the side wall when the lid is in the closed position. In some embodiments, the side covers at least 40% of the side wall when the lid is in the closed position. In some embodiments, the side covers up to 90% of the side wall when the lid is in the closed position. In some embodiments, the side covers up to 80% of the side wall when the lid is in the closed position. In some embodiments, the side covers up to 70% of the side wall when the lid is in the closed position. In some embodiments, the manufacturing process includes providing different box sizes, for example boxes having sidewall heights of either 10 cm, 11.5 cm, 13.5 cm or 16 cm, and each box may be provided with the same lid that fits all the box sizes provided, for example a lid having a side height of 7 cm. In some embodiments, the side height is greater than 3 cm. In some embodiments, the side height is greater than 5 cm. In some embodiments, the side height is greater than 6 cm.

A support element structure according to the present disclosure can include a support element distal end that is located at a particular depth when the lid is in a closed position. In some embodiments, the depth is at least 3 mm and less than 50 mm from the top of the lid. In some embodiments, the depth is at least 5 mm and less than 50 mm from the top of the lid. In some embodiments, the depth is at least 15 mm and less than 40 mm from the top of the lid. In some embodiments, the depth is at least 20 mm and less than 35 mm from the top of the lid. The depth of the support element structure is responsible for reinforcing the structure of the consumer product. The combination of the depth and shape of the support element structure and the amount of clearance distance can allow for avoiding twisting of the lid.

In some cases, a force is applied to the side in a direction perpendicular to the base of the box, from the base of the box toward the top of the lid. Such a force may be applied, for example, when lifting the box off the floor to transport it. In such a situation, the clearance distance separating the sidewall from the support element structure may be reduced to zero as the weight of the contents and the box is applied to the locking tab through the actuator. In such a situation, the support element structure allows the box to avoid accidental opening by the sidewall sinking to the point where the actuator releases from the locking tab, causing the box to fall to the floor and leaving the lid in the hands of the person lifting the box by holding the box by the lid. In this and some other examples, the detergent product weighs more than 50% of the weight of the consumer product, and the gravity force generated by the detergent product on the base of the box in the absence of a reaction force on the base of the box results in the deflection of certain portions of the sidewall and a reduction in the clearance to zero, and when the clearance is reduced to zero and no actuation pressure is applied, the actuator maintains abutment against the locking tab. In some examples, the detergent product weighs more than 70% of the weight of the consumer product in such a situation. In some embodiments, in such situations, the weight of the detergent product is greater than 80% of the weight of the consumer product.

In some cases, a force is applied to the actuator in a direction perpendicular to the side wall, towards the inside of the box, for example by gripping the lid with one hand, with the thumb on one side and the fingers on the other side. Such a force may be applied, for example, when lifting the box from the floor and transporting it. In such a situation, the clearance distance may be reduced to zero due to the force of pinching the side wall between the support element structure and the actuator. In such a situation, the static friction forces between the side wall and the support element structure make it possible to avoid an accidental opening of the box by the lid coming off the side wall, causing the box to fall to the floor, and by holding the box by the lid, the lid remaining in the hands of the person lifting the box.

In one embodiment, the container is made from a cardboard material, thereby making it from a material that can be recycled.

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 a water-soluble film. The at least one compartment includes a cleaning composition. The water-soluble film is sealed to prevent the cleaning composition from leaking out of the compartment during storage. However, when the water-soluble unit dose article is added to water, the water-soluble film dissolves and releases the contents of the inner compartment into the wash fluid. 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 at least five compartments. The compartments may be arranged in a nested orientation, i.e., one on top of the other. Alternatively, the compartments may be in a side-by-side orientation, i.e., one adjacent to the other. The compartments may be in a "tire and rim" configuration, i.e., a first compartment is adjacent to a second compartment, but the first compartment at least partially surrounds the second compartment but does not completely encapsulate the second compartment. Alternatively, one compartment may be completely encapsulated within another compartment. In some embodiments, the unit dose article includes at least two compartments, one of which is smaller than the other compartment. In some embodiments, the unit dose article includes at least three compartments, two of which may be smaller than the third compartment, and in some embodiments, the two smaller compartments are nested within the larger compartment. In some embodiments, the unit dose article includes at least four compartments, three of which may be smaller than the fourth compartment, and in some embodiments, the three smaller compartments are stacked on the larger compartment.

7A-7J show an exemplary method of manufacturing a consumer product and container, where the container contains a detergent product, the detergent product preferably including a flexible water-soluble unit dose article, the container includes a box, a lid, and a lock for maintaining the lid in a closed position, and the method includes folding a blank 500 to erect a support element structure as part of the lid. Although this particular exemplary method refers to a blank 500, such a method may be used with other blanks described herein.

In FIG. 7A, starting with a blank 500, a side panel 101 connected to a side flap 401 is folded over the side panel 104 along a fold line that separates the side panel 101 from an adjacent side panel 104. The side flap 401 includes adhesive 411, which may be applied after folding, for example.

In FIG. 7B, starting with the resulting structure as shown in FIG. 7A, side panel 102 is folded over side panel 103 along a fold line separating side panel 102 from adjacent side panel 103, and side panel 102 is glued to side flap 401 once folded over.

For example, as shown in Figures 7A and 7B, an exemplary method actually involves folding the side flap and two of the side panels (in this case 102 and 101) over the other two side panels (in this case 103 and 104) so that the side flap faces one of the other two side panels (in this case 102) to close the side structure by gluing the side flap to one of the other two side panels. Following this, the closed side structure can be opened to erect the sides to obtain a structure as shown in Figure 7C. It is noted that a configuration as shown in Figure 7B is particularly space-efficient for transportation, since it is flat and compact, for example when the initial manufacturing steps are performed at the supplier's facility. Alternatively, these folding steps can be performed at a single manufacturer's site.

After opening the closed side structure, the formation of the top panel can begin by folding the first of the three lid flaps, the first lid flap being the lid flap connected to the opposing side panel 103, as shown in FIG. 7D.

After folding the first lid flap as shown in FIG. 7D, one can proceed to fold the support element first panel such that it contacts the first lid flap to form the support element structure as shown in FIG. 7E. It is important to understand that proceeding to fold the lid flap connected to the opposing side panel precedes the folding of the support element first panel, and thus the support element first panel is ultimately sandwiched between the opposing side panel and the top panel as shown.

After folding the support element structure as shown in FIG. 7E, the remaining two lid flaps can be folded, pushing the support element structure away from the top panel, and proceeding to form the top panel, as shown sequentially by FIGS. 7F-7I. In this embodiment, the wings push the support element structure away from the side panels.

The resulting lid, as shown in FIG. 7J, can then be combined with the box shown in FIG. 6 to obtain a consumer product according to the present disclosure.

When liquid, the laundry detergent composition may be Newtonian or non-Newtonian. In some embodiments, the liquid laundry detergent composition is non-Newtonian. Without wishing to be bound by theory, non-Newtonian liquids have different properties than Newtonian liquids, more specifically, the viscosity of non-Newtonian liquids depends on the shear rate, while Newtonian liquids have a constant viscosity regardless of the applied shear rate. It is believed that the decrease in viscosity of non-Newtonian liquids upon the application of shear further promotes the dissolution of the liquid detergent. The liquid laundry detergent compositions described herein may have any suitable viscosity, depending on factors such as the formulated ingredients and the purpose of the composition.

Dimensions and values disclosed herein should not be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise indicated, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean "about 40 mm."
