Detailed description

Cardboard is, mechanically speaking, a relatively flexible material, meaning that a wall of a container made of cardboard may offer little resistance to bending under external pressure. In some applications where bending resistance is important, a material other than cardboard may be used. However, materials other than cardboard may not be as easy to recycle. This choice of material is, in this way, the result of an intermediate solution. An object of the present description is to propose a structure with a cardboard support element for a cardboard container, where the inclusion of said structure with a support element in a cardboard container leads to a reinforcement of the cardboard structure, which allows the use of cardboard in applications that would otherwise be compromised by the use of another material, while avoiding compromising recycling.

The design of the cardboard container can address the mechanical strengthening characteristics by applying separate three-dimensional pieces. Such three-dimensional pieces can be applied to a lid, for example by gluing. Bonding can occur before or after cap formation. When gluing a three-dimensional part onto a flat structure, such as a preform, at a supplier's facility, transportation from the supplier's facility may be less space-efficient, and therefore less cost-effective, due to the three-dimensional nature. of three-dimensional pieces that affect stacking. If such gluing were to occur after transportation from a supplier location, for example, on a manufacturing line, gluing a three-dimensional part onto a preform or inside a cap vertically during manufacturing can add complexity to a manufacturing operation and slow down the speed of a manufacturing line, consequently compromising the productivity of the manufacturing plant. The cardboard lid comprising a structure with a support element according to the present description was surprisingly identified as a way to create a three-dimensional reinforcement structure that reduces or eliminates a negative impact on transportation efficiency or manufacturing line speed. in manufacturing facilities. As the cardboard lid comprising a structure with support member according to this disclosure can be formed using folding machinery that is likely already on site at the manufacturing facility, little or no additional capital is required at the manufacturing facility to execute structures according to this description. Furthermore, the cardboard lid comprising a structure with a supporting element according to this description belongs to a single preform, thus facilitating the manufacture of said cardboard lid comprising a structure with a supporting element. Cutting of a single such preform may take place at a supplier's facility prior to transport to manufacturing facilities where the preforms may be placed vertically. Furthermore, a single preform can be in the form of a flat preform and transportation can also be facilitated and therefore weight and cost can be optimized. Furthermore, a single flat preform may be partially prefolded, for example, at a supplier's facility, to further optimize transportation efficiency through a smaller 2D (two-dimensional) footprint or through reducing elements of a preform that adheres to a given footprint while maintaining the flat and , therefore, the stacking capacity of the preform.

A cardboard lid or preform according to this description may be made of the same material as a material used for a box according to this description. A preform, a lid, a box or a container according to this description may be made of paper or cardboard materials, wherein the paper material is selected, for example, from cardboard, paperboard, laminates comprising at least one layer of cardboard or cardboard, cellulose pulp materials or a mixture thereof. The material used to manufacture the preform, lid, box or container may comprise other ingredients, such as colorants, preservatives, plasticizers, UV stabilizers, oxygen, perfume, recycled materials and moisture barriers or a mixture thereof. . The preform, lid, box or container may comprise external or internal printing areas. The preform, lid, box or container may be made, for example, of cardboard. Processes for manufacturing a suitable preform, lid, box or cardboard container may include, but are not limited to, a tubular formation from a flat cardboard or sheet of paper with a step of gluing, folding or a mixture of them. The preform, lid, box or cardboard container is opaque, for example, to protect the contents from outside light. In some examples, the preform, lid, box or container is constructed, at least in part and in some specific examples entirely, of paper-based material. By paper-based material, herein, is meant a material comprising paper. Without wishing to be limited by theory, "paper" is meant herein as a material made from a cellulose-based pulp. In some examples, the paper-based material comprises paper, cardboard, or a mixture thereof, where preferably, the cardboard comprises cardboard paper, corrugated cardboard, or a mixture thereof. The corrugated fiber board comprises a series of grooves. Each groove can be understood as a channel. The grooves extend parallel to each other, the groove direction being the direction traveled along each channel. The paper-based material may be a laminate comprising paper, cardboard, or a mixture thereof, where in some examples, the cardboard comprises paperboard, corrugated cardboard, or a mixture thereof, and 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, polyethylene terephthalate, polypropylene, polyvinyl alcohol, or a mixture thereof. In some examples, the plastic material comprises a copolymer of ethane and vinyl alcohol, or EVOH. A barrier material may be used as the at least one other material. The barrier material may be a biaxially oriented polypropylene, a metallized polyethylene terephthalate, or a mixture thereof. The at least one other material may comprise a wax, a cellulose material, polyvinyl alcohol, silica dioxide, casein-based materials or a mixture thereof. In some examples, the paper-based laminate comprises more than 50%, preferably more than 85%, and more preferably more than 95% by weight of a laminate of fiber-based materials. In some examples, the barrier material may comprise plastic material having a thickness of between 10 micrometers and 40 micrometers. In some examples, the barrier material may comprise plastic material having a thickness of between 10 micrometers and 35 micrometers. The paper-based material may be a laminate. In some examples, the inner surface of a preform, a lid, a box or a container comprises paper, paperboard or a mixture thereof, wherein, in specific examples, the paperboard comprises paperboard, corrugated paperboard and polyethylene laminate, or a mixture thereof, and, in some examples, the external surface of the preform, lid, box or container or a combination thereof comprises the at least one other material. Alternatively, the at least one other material may also be laminated between two layers of paper-based material. Without wishing to be bound by theory, this at least one other material could act as a barrier to filtrate absorbed by the paper-based material facing the interior side of the preform, lid, box or container, to prevent or reduce a contaminant flow through a wall of the preform, lid, box or container. Other structures may be considered efficient to prevent leakage of the contents or to protect the contents from external fluids, for example, from a shower or sink, or when handling the container or lid with wet hands. Contamination of a wall, flap or panel of the preform, lid, box or container could be unsightly to consumers or may contaminate the storage area. Other structures could be considered efficient to avoid exposure of the contained detergent product with respect to the external relative humidity. This is especially important if the contained detergent product is moisture sensitive in nature such as, for example, water-soluble unit dose detergent articles in which a detergent composition is contained in a water-soluble film, the film being soluble. in water sensitive to premature breakage when exposed to higher percentages of outdoor relative humidity. In some examples, the preform, lid, box or container is made of a paper-based material comprising the at least one other material laminated between two layers of corrugated cardboard. In some examples, the material used for the preform, lid, box or container comprises a corrugated material with a cardboard core sandwiched between two layers of smooth cardboard and a polyethylene laminate. A cardboard box, lid or preform according to this description may be made from, or comprise, recycled material or recycled cellulose fibers.

Figure 1 illustrates an illustrative cardboard lid 100 for a container. The cardboard lid 100 comprises side panels 101-104 that form flanks of the lid. In this example, each side panel 101-104 is a rectangular side panel. In this example, four side panels are provided, each side panel forming a respective lid flank. In this example, each lid flank is connected to two other lid flanks by a corner of the lid, each corner of the lid forming a 90 degree angle. In this example, all the sides of the lid are perpendicular to the same plane. The cardboard lid 100 further comprises lid flaps connected to the side panels by fold lines of the lid flaps, two of the lid flaps forming a top lid panel 105 where, in this example, the two lid flaps that form the top panel of the lid are two opposite lid flaps, being in this case said two opposite lid flaps forming the top panel connected to long side panels, this example comprising two long side panels and two short side panels, a short side panel being shorter than a long side panel along a first direction, the first direction according to this description 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 flank of the lid. The illustrative lid flaps forming the top panel will be illustrated 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 because they belong to a single preform as will be explained in more detail. A flap should be understood as a piece of cardboard connected to the structure of the rest of the cover. A flap may be connected to the structure of the rest of the lid by a fold line, the lid being made from an integral piece of cardboard. The flap may be connected to the cardboard structure by a segment, for example the fold line. A flap may also be connected to a part of the lid with glue.

Normal or perpendicular should be understood in this description as substantially normal or substantially perpendicular. In some examples, normal or perpendicular includes angles of less than 120 and more than 60 degrees. In some examples, normal or perpendicular includes angles of less than 110 and more than 70 degrees. In some examples, normal or perpendicular includes angles of less than 100 and more than 80 degrees. In some examples, normal or perpendicular includes angles of less than 95 and more than 85 degrees.

The cardboard lid 100 further comprises a support member structure 106 extending away from the top panel and positioned between the side panels. Extending away from the top panel should be understood as the support member structure comprising at least a portion that extends away from the top panel, the support member structure developing a three-dimensional shape, defining the cardboard material of the support member structure. support some limits of this three-dimensional form. In some examples, the support element structure comprises a portion separated from the top panel by at least 5 mm. In some examples, the support element structure comprises a portion separated from the top panel by at least 10 mm. In some examples, the support element structure comprises a portion separated from the top panel by at least 15 mm. In some examples, the cardboard structure comprises a portion separated from the base plane by at least 20 mm. In some examples, the support element structure comprises a portion separated from the top panel by at least 30 mm. In some examples, the support element structure comprises a portion separated from the top panel by at least 35 mm. In some examples, the support structure comprises a portion separated from the top panel by less than 10 cm, for example, to avoid a cantilever situation when the support structure acts as such. In this example, the support structure 106 has a triangular cross section in a plane perpendicular to the top panel 105. In other examples, the support structure may comprise a portion of a cylinder or a portion of a prism, such as such as a triangular, tetragonal or pentagonal prism for example. Such prisms can be obtained by folding successive parts of the support structure along parallel lines, while a shape of a part of a cylinder can be obtained by tensioning a single panel of the support structure. In some examples, the structure with support element comprises an arched shape because the structure with support element is tensioned between other elements, said other elements being part of the lid.

The structure with a support element according to this description is intended to provide mechanical support to a cardboard wall, for example, a cardboard wall of a container or a lid of a container, said cardboard wall being supported against the support element if subjected to a force or a pressure.

The illustrated support element structure 106 corresponds to a part of a prism, more specifically a triangular prism when the upper panel 105 is taken into account. In this example, the support element structure comprises a linear edge 107, corresponding edge 107 to an edge of the prism, a first 108 and a second 109 side of the prism defining the edge 107, preferably each of the first 108 and second 109 side of the prism forming an angle of more than 15 degrees (respectively -15 degrees) with the top panel. In this case, the first side 108 of the prism forms an angle of approximately 30 degrees with the top panel. In some examples, the edge is separated from the top panel by at least 5 mm. In some examples, the edge is separated from the top panel by at least 10 mm. In some examples, the edge is separated from the top panel by at least 15 mm. In some examples, the edge is separated from the top panel by at least 20 mm. In some examples, the edge is separated from the top panel by at least 30 mm. In some examples, the edge is separated from the top panel by at least 35 mm. In some examples, the edge is separated from the top panel by less than 10 cm, for example, to avoid a cantilever situation when the supporting element acts as such.

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

The cardboard lid 100 is such that the lid flaps, the side panels and the structure with supporting element belong to a single preform.

The fact that the lid flaps, the side panels and the structure with support element belong to a single preform makes it possible to limit the complexity in vertically placing said lid, where a lid that comprising a plurality of preforms may involve additional steps of gluing or fitting between different independent structures, for example.

Figure 2A illustrates another illustrative cardboard lid 200 according to this description. The cardboard lid 200 comprises elements 101-109 as described in the case of the cardboard lid 100, said elements being numbered using the same reference numbers. The cardboard lid 200 further comprises a reinforced lid flank 104, the reinforced lid flank 104 comprising a reinforced section 204. In fact, in some examples, at least one of the flanks of the lid, preferably some of the flanks of the lid and, most preferably, each of the flanks of the lid, comprise a reinforcement panel, the reinforcement panel being connected to the respective side panel by a fold line of the side panel, such as a fold line 214 of the side panel, the reinforcement panel folding back over the respective side panel, the reinforcement panel belonging to the single preform. In some examples, the lid comprises two opposing long flanks parallel to each other and two opposite short flanks parallel to each other, the long flanks being perpendicular to the short flanks, the long flanks being reinforced while the short flanks are unreinforced or thinner. that long flanks, or comprise a smaller number of layers than long flanks, to take into account the fact that a user or consumer may be more likely to apply pressure on long flanks, and that long flanks are more likely to be subject to deformation since their midpoint along the first direction is further from the corners of the same long flank than the midpoint of a short flank is from the respective short flank corners.

The cardboard lid 200 further comprises a drive area 210. In fact, in some examples, at least one flank comprises an actuation area. In this example, a vertex of the support member structure, such as edge 107, is in line with drive area 210. Such an actuation area may allow actuation of a closure of a container comprising a lid according to this description as will be described in more detail in this description. In a preferred example, two flanks comprise such actuation areas, preferably two opposing flanks, more preferably two opposing long flanks, where, in some examples, consumers tend to use a single part of a hand to actuate both actuation areas at the same time. time, where a part of the hand can be adapted in such an example to the length of the short flanks along the first direction to reach both actuation areas simultaneously.

Figure 2B illustrates another illustrative cardboard lid 220 according to this description. The cardboard lid 220 comprises elements 101-109 as described in the case of the cardboard lid 100 and elements 204, 214 and 210 as described in the case of the cardboard lid 200, said elements being numbered using the same numbers. reference. The cardboard lid 220 further comprises a reinforcement panel 213 connected to the respective side panel 103, and additional reinforcement panels connected to the respective side panels 102 and 101 that are not visible in this Figure. Thus, the cardboard lid 220 is made such that each of the flanks of the lid comprises a reinforcing panel, the reinforcing panel being connected to the respective side panel by a fold line of the side panel, the reinforcing panel rearwardly on the respective side panel, the reinforcing panel belonging to the single preform. The cardboard lid 220 also comprises a further or additional actuation area 210B, the vertex 107 being in line with the actuation area 210B, the actuation area 210B in this case being a round opening in the side panel 102 opposite the side panel. 104 comprising the drive area 210 which also takes the form of a round opening in this case.

Figure 3 illustrates another example of cardboard lid 300 according to this description. The cardboard lid 300 comprises elements 101-105 as described in the case of the cardboard lid 100, said elements being numbered using the same reference numbers. The cover 300 comprises the structure 306 with support element according to this description which is a part of a cylinder. The structure 306 with support element may be formed by a flap 306 connected by a fold line to the side panel 101 and inserted between the top panel 105 and a flap 307 connected by a fold line to the side panel 103, said flap 306 being tensioned. with an arched shape to form the structure with a support element.

Figure 4 illustrates an illustrative cardboard preform 400 for a cardboard lid according to this description, in particular according to a cardboard lid similar to the illustrative cardboard lid 300. The cardboard preform 400 comprises:

- four side panels 104, 101, 102, 103, the four side panels contiguous along a first direction D1, each side panel being connected to at least one other side panel by a fold line of the respective side panel perpendicular to the first address;

- a side flap 401 connected to one of the side panels, in this case the side panel 103, along a folding line perpendicular to the first direction, following or preceding the side flap 401, in this case following, the four side panels along the first direction;

- three lid flaps 404, 402, 307, the lid flaps one after the other along the first direction, each lid flap being connected to a respective regular side panel 104, 102, 103 of the four side panels along a respective lid flap folding line parallel to the first direction, the lid flap folding lines being aligned with each other; the four side panels comprising the regular side panels and a specific side panel;

- a structure with a support element, the structure with a support element comprising a first panel 306 of the support element connected to the specific side panel 101 by a specific fold line aligned with the fold lines of the flap of the lid, further comprising the structure with support element an opposite panel 307 of support element included in the flap 307 of the lid of the three flaps 404, 402, 307 of the lid, the flap 307 of the lid being connected to an opposite side panel 103, the opposite side panel 103 being the regular side panel separated from the specific side panel 101 by another single regular side panel 102, the structure with supporting element having a combined length L2A+L2B along a direction D2 perpendicular to the first direction D1 exceeding a length L1 of the other single regular side panel 102 along the first direction D1, where the three lid flaps comprise the opposite support member panel and two lid flaps 402, 404 to form a top panel of the cover.

It should be understood that a number of other configurations can be considered. For example, in some cases the flap 401 may be attached to the panel 104. A function of a flap such as the flap 401 allows, for example, gluing to obtain the four-sided structure ready for vertical placement, and also allows forming a flat reduced footprint structure as illustrated, for example, in Figure 7B.

It should be understood that, in this description, "aligned" may encompass folding lines in the same direction that may be slightly offset from each other, for example to take into account the thickness of the material. In some examples, such displacement considered to maintain alignment may be less than three times the thickness of the material forming the preform. In some examples, such displacement considered to maintain alignment may be less than twice the thickness of the material forming the preform. In some examples, such displacement considered to maintain alignment may be less than the thickness of the material forming the preform.

The combined length according to this description is a combined length along the direction perpendicular to the first direction of one or more elements that form the structure with vertical support element, without double counting of eventual sections of said elements configured to overlap them, or glue them together, on said support element vertically, in particular a combined length sums the length along the direction perpendicular to the first direction of the elements connected to the specific side panel 101 and to the opposite side panel 103 and which are extends beyond the respective side panels along this direction perpendicular to the first direction. Said combined length may correspond to a peripheral length of the structure with vertical support element, the peripheral length, for example, extending from one corner to another of the cover vertically, passing through a vertex of the structure with support element, along a cross section of the vertically supporting member structure along a plane parallel to the other single vertically regular side panel, while following the supporting member structure. The fact that said combined length exceeds a length of the other single regular side panel along the first direction reflects the fact that the support member structure extends away from the top panel and therefore has a peripheral length from a end of the top panel to an opposite end of the top panel along the first direction that exceeds the length of the top panel itself along this same direction. In the case of lid 300, for example, the length along the cylindrical portion, corresponding to a curve, actually exceeds a length of one segment between points on the cylindrical portion that intersect the top panel. Similarly, in the case of cover 100, 200 or 220, the length along the triangular section of the support member structure will exceed the length of the separation points of a segment of the triangular structure that intersects the top panel. The fact that the support element structure extends away from the top panel in the lid vertically is therefore equivalent to the fact that the combined length exceeds, in the preform, the length of the single regular side panel. It should be understood that said combined length corresponds to the total length of the elements, in the preform, of the various elements that form the support element, which differs precisely from a length of the vertical support element in the vertical cover. It should also be noted that some of the various elements that form the support element may be configured to be fully or partially glued together when the support element is formed vertically, in which case a length of such fully or partially section configured to be glued to form a double-layer structure may not contribute to said double-combined length. In some examples, all preform elements connected to the specific side panel and extending beyond the specific side panel have a specific combined length along the direction perpendicular to the first direction that exceeds a length of the other single side panel. regular along the first direction, thereby ensuring that the combined length exceeds a length of the other single regular side panel along the first direction, where the combined length comprises the specific combined length. In other words, even if the side panel 307 of length L2B opposite the support member were to be completely glued, to make the support member vertical, to the first panel 306 of length L2A of the support member, the support member would be vertical due to L2A, corresponding in this case exactly to the peripheral length of the structure with vertical support element, being longer than L1.

Figure 5 illustrates an illustrative cardboard preform 500 for a cardboard lid according to this description, in particular according to a cardboard lid similar to the illustrative cardboard lid 220. The cardboard preform 500 comprises the following elements, some of which correspond to corresponding elements of the cardboard preform 400 and therefore correspond to the same reference number:

- four side panels 102, 103, 104, 101, the four side panels contiguous along a first direction D1, each side panel being connected to at least one other side panel by a fold line of the respective side panel perpendicular to the first address;

- a side flap 401 connected to one of the side panels, in this case the side panel 101, along a folding line perpendicular to the first direction, following or preceding the side flap 401, in this case following, to the four side panels along the first direction (in another example, said side flap 401 could precede the side panel 102);

- three lid flaps 402, 507, 404, the lid flaps contiguous along the first direction, each lid flap being connected to a respective regular side panel 102, 103, 104 of the four side panels by a respective lid flap folding line parallel to the first direction, the lid flap folding lines being aligned with each other; the four side panels comprising the regular side panels and a specific side panel;

- a structure with a support element, the structure with a support element comprising a first panel 506 of a support element connected to the specific side panel 101 by a specific fold line aligned with the fold lines of the flap of the lid and by an additional fold line parallel to the specific fold line, the support member structure further comprising an opposing support member panel 507 comprised in the lid flap of the three lid flaps and connected to an opposite side panel 103, the opposite side panel 103 being the regular side panel separated from the specific side panel 101 by a single other regular side panel 104, the structure with supporting element having a combined length (corresponding in this case exactly to the peripheral length of the structure with vertical support element L2C+L2D-L2D2, as will be explained below) along a direction D2 perpendicular to the first direction D1 that exceeds a length L1 of the other single regular side panel 104 along the first direction D1, where the three lid flaps comprise the opposite support member panel and two lid flaps 402, 404 to form a top lid panel.

The cardboard preform 500 further comprises a first wing 510, the first wing 510 being adjacent to the first panel 506 of the support member and connected to the first panel 506 of the support member by a fold line of the first wing perpendicular to the first direction. .

An illustrative wing such as the first wing 501 may, for example, help the support structure act as a centering patch on the lid to correctly position and align the lid on the corresponding container, thereby guiding the lid. during closing of the container. An illustrative wing such as the first wing 501 may also contribute to increasing manufacturing tolerance by compensating for some degree of misalignment. An illustrative wing such as the first wing 501 can also contribute to increasing the consumer experience by facilitating closure of the container.

Said first wing can be comprised in different illustrative preforms according to this description to obtain different illustrative covers according to this description, where the structure with a support element of such covers would comprise a first panel of a support element and the first wing, the first wing being adjacent to the first panel of the support element and separated from the first panel of the support element by a first fold line of the first wing, the first wing comprising a distal end of the first wing from the fold line of the first wing, being the end of the first wing in contact with the top panel to keep the first panel of the support member extended away from the top panel. When folded into place from the preform, said first wing would fold parallel to a flank of the lid (in the example of preform 500, parallel to the flank 104 of the lid), the distal end (for example, the distal end 511) would rest against the top panel 105 (for example formed by flaps 402 and 404), pushing the first panel of the support element (for example 506) away from said top panel to make an illustrative lid according to this description. In some examples, the distal end may be curved to facilitate sliding of the first wing against the top panel when the lid is placed vertically. In other examples, the distal end may be straight, for example to facilitate cutting the preform.

The cardboard preform 500 comprises a second wing 520, the second wing being adjacent to the first panel of the support element and connected to the first panel of the support element by a fold line of the second wing perpendicular to the first direction and on one side of the first panel of the support element opposite the first wing 510. It should be noted that, although the illustrative preform 500 comprises both a first and a second wing, another illustrative preform, not illustrated here, may comprise a single wing.

Said first wing can be comprised in different illustrative preforms according to this description to obtain different illustrative covers according to this description, where the structure with support element of such covers would comprise the second wing, the second wing being adjacent to the first panel of the support element and separated from the first panel of the support element by a fold line of the second wing, the second wing comprising a distal end of the second wing from the fold line of the second wing, the end of the second wing being in contact with the top panel to keep the first panel of the support member extended away from the top panel, the fold line of the second wing and the fold line of the first wing being on opposite sides of the first panel of the support member.

In this illustrative preform 500, the end of the first wing and the end of the second wing are round to facilitate verticalization of the lid. In this example, the shape of the second wing is a mirror image of a shape of the first wing along a direction D2 perpendicular to the first direction D1 to extend the structure with supporting element in a balanced way.

In the illustrative preform 500, the first wing 510 corresponds to a cutout in one of the three lid flaps adjacent to the first panel of the support element, specifically in this case to a cutout in the flap 404. In this illustrative preform 500, The second wing 520 corresponds to a cutout in one of the three lid flaps adjacent to the first panel of the support element, specifically in this case to a cutout in the flap 402. In some other examples, said cutout may correspond to a single to the.

In the illustrative preform 500, the structure with support element comprises a connection panel 508 between the first panel 506 of the support element and the specific side panel 101. Said connection panel, in this example, is directly connected to the specific panel by the specific fold line and directly connected to the first panel of the support element by the additional fold line parallel to the specific fold line. Directly connected should be understood as a single fold line making such a connection. The connected panel, when the preform is upright to form a lid, may remain essentially parallel to the top panel, while the first panel of the support member extends away from the top panel.

In the illustrative preform 500, the support element structure comprises an opposing connection panel 509 between the opposite support element panel 507 and the opposite side panel 103. Said structure may allow, for example, to retain the first element panel 506 support in place when the lid is placed vertically from the preform. In this example, the opposite panel 507 may coincide with an additional panel 530 when the preform is upright in a lid, said additional panel 530 being directly connected to the first panel of the support element on a side opposite the connection panel 508. Such relationships will be explained in more detail in an illustrative manufacturing method. It should be noted that, in some examples, the connection panel 508 and the opposite connection panel 509 have substantially the same length along the direction D2 to place the support element in a central position such that a vertex of the support element support can be positioned aligned with an opening for an actuation area which can be located at a midpoint, along direction D1, of the corresponding side panel. Similarly, a desired positioning of the vertex can be obtained by varying the respective length of the panels 508 and 509 accordingly.

In this illustrative preform 500, and as explained in the context of the preform 400, it should be understood that the combined length corresponds to the total length of the elements, in the preform, of the various elements that form the support element, which differs precisely one length of the vertical support element in the vertical cover. It should also be noted that some of the various elements that form the support element may be configured to be fully or partially glued together when the support element is formed vertically, in which case a length of such fully or partially section configured to be glued to form a double-layer structure may not contribute to said double-combined length. In some examples, all preform elements connected to the specific side panel and extending beyond the specific side panel have a specific combined length along the direction perpendicular to the first direction that exceeds a length of the other single side panel. regular along the first direction, thereby ensuring that the combined length exceeds a length of the other single regular side panel along the first direction, where the combined length comprises the specific combined length. In other words, even if the opposite support member side panel 507 were to be glued, to make the support member vertical, to the additional panel 530, the support member would be vertical because L2D+L2C minus a length L2D2 along D2 of the section glued between 507 and 530 would be longer than L1.

The illustrative preform 500 further comprises four reinforcement flaps 540, each reinforcement flap being connected to a respective side panel by a fold line of the respective reinforcement flap, the fold lines of the reinforcement flap being aligned with each other and being parallel to the first direction, the reinforcement flaps being located on one side of the side panels opposite to the flaps of the lid and the structure with supporting element. In this representation, for ease of illustration, the reinforcement flaps are illustrated folded back over the respective side panels. It should be noted that a preform having such a folded flap configuration can be used to facilitate transportation of a preform to reduce the size of the preform while keeping the preform substantially flat. Said reinforcement flaps can be glued to the respective side panels. Such reinforcement flaps can reinforce the respective side panels and therefore the entire structure.

In the illustrative preform 500, the specific side panel 101 and the opposite side panel 103 are shorter side panels, the shorter side panels having the same panel length along the first direction, this same panel length being shorter. than a panel length of the other two side panels 102 and 104 along the first direction, the other two side panels being long side panels, the long side panels having the same length L1 along the first direction. In some examples, the length of the short panels is less than 80% of the length of the long panels along the first direction. In some examples, the length of the short panels is less than 70% of the length of the long panels along the first direction. In some examples, the length of the short panels is less than 60% of the length of the long panels along the first direction. In some examples, the length of the short panels is less than 50% of the length of the long panels along the first direction. In some examples, the length of the short panels is more than 10% of the length of the long panels along the first direction. In some examples, the length of the short panels is more than 20% of the length of the long panels along the first direction. In some examples, the length of the short panels is more than 30% of the length of the long panels along the first direction. The use of a relatively short length for the short panels that carry the structure with support element makes it possible to make said structure with support element relatively more elastic, reducing the overhang. In some examples, the length of the short panel preferably fits a portion of a consumer's hand, with an internal volume or cavity of the corresponding container being established by establishing a length of the long panels to achieve a desired capacity or fill level at a given height of the container.

In illustrative preform 500, each long side panel comprises a respective opening for an actuation area, where each respective opening is preferably a through opening intersecting grooves comprised in the long side panels. Said configuration not only makes it possible to provide areas of action, but also to do so in relation to the positioning of the support element, and to allow ventilation of the long side panels through such intersected grooves, with said long side panels being more likely to weaken in a humid environment, compared to short panels, due to their greater length which makes them less elastic. Said relative positioning of the openings, the support element, the short and long panels makes them all work together and contributes to making the cardboard structure more resistant.

Preforms according to this description can be conveniently transported as a stack of a plurality of flat or substantially flat preforms. In some examples, preforms in a stack comprise back-folded and preferably glued reinforcement flaps to reduce the 2D footprint of the preform, resulting in a not perfectly flat but still stackable preform. Such stacks facilitate the verticalization of the corresponding caps in a manufacturing facility separate from a facility that manufactures the preforms.

Figure 6 illustrates an illustrative consumer product 600 comprising a detergent product (not visible in Figure 6) and a container, the container comprising a box 601 and a lid corresponding, in this example, to the lid 220, although they may be considered other caps according to this description. The box 601 comprises a closure 610 for maintaining the lid in a closed position, the closure comprising an actuator aligned with a portion of the support structure when the lid is in the closed position, the support structure engaging within the box when the lid is in the closed position. Closure 610 cooperates with drive area 210B. An additional closure may be provided to cooperate with the opening 210, such additional closure being on the rear side of the box and being a mirror image of the closure 610 located on the front side of the box.

Detergent products are products that may be relatively heavy, for example, when a container for such product carries the total weight of such detergent products, in particular, when the consumer product is recently purchased and therefore maintains a significant quantity of detergent product. Although some consumers may lift and carry said consumer product containing a base from a box containing said detergent product, said lifting and carrying may also occur by holding said consumer product by a lid, without holding the base. In such cases, it is possible that the lid, subjected to the force of gravity of the detergent product, may become loose and open the box, dropping the box and possibly spreading its contents. Such situations should be avoided. Beyond preventing such unintentional lid unlocking, the structure of a consumer product container must maintain or improve the ergonomics of the opening and prevent or reduce permanent sidewall deformation under excessive or repetitive application of forces applied to the lid. consumer product, for example during transport in a supermarket bag, against other objects, when subjected to external pressure or when dropped. At the same time, packaging can be produced in order to preserve the environment. The consumer product according to this description aims to take these different aspects into account.

A consumer product should be understood in this description as a product that is provided, among others, to final consumers. Such consumer products may, for example, be available for purchase in supermarkets and end consumers may store such consumer products in their homes. Consumer products can be provided in large quantities and therefore must be designed with environmental concerns in mind. Consumer products must also be designed with transportation to a retail store in mind. Consumer products should also be designed with display storage in a retail store in mind. Consumer products must also be designed with transportation from a retail store to a consumer's home in mind. Consumer products must also be designed with storage in a private end consumer's home in mind. Consumer products must also be designed taking into account the use of the consumer product in a private end consumer's home. Consumer products must also be designed with disposal in mind.

The consumer product according to this invention comprises a detergent product. Detergent products are to be understood in this description as products comprising a surfactant. Detergent products may also comprise bleach or other ingredients. Exemplary detergent product compositions are described in more detail herein. In some examples, the detergent product comprises unit dose detergent pouches, preferably soluble unit dose detergent pouches. in water, more preferably flexible water-soluble unit dose detergent bags. Examples of unit dose detergent pouches are described in more detail herein.

The consumer product according to this invention further comprises a container. A container should be understood in this description as an object that houses a content, for example, in a cavity of the container. The container facilitates the protection, transportation, storage, access and disposal of the consumer product. In this description, the container comprises a box. A box should be understood as a generally parallelepiped, barrel-shaped, cylindrical, round, oval or three-dimensional cubic object that defines a cavity. The use of parallelepiped boxes can facilitate storage and transportation by allowing boxes to be stacked in a space-efficient manner. In some examples, a box may be a parallelepiped provided with some trapezoidal or rounded conical beveled edges. The box according to this description comprises the detergent product. It should be understood that the detergent product is contained or stored in the box. The box according to this description comprises a base, side walls and an opening. A base according to this description should be understood as a surface on which the box can extend when placed on a supporting surface such as a shelf or floor. In some examples, the base is flat. In some examples, the base is rectangular. In some examples, the base is oval or round. In some examples, the base is flat. In some examples, the base has an engraved profile that protrudes or is raised in relief. Side walls according to this description are to be understood as extending from the base, and connecting the base to the opening, to a transition piece, or to the lid. It should be understood that the connection of the base to the opening may include a transition piece in addition to a side wall. A transition piece may be glued or otherwise attached to the side wall, for example. In some examples, the side walls are perpendicular to the base. In some examples, the base is rectangular and has four sides, four side walls extending perpendicularly from the base, each side wall being rectangular, each side wall being connected by one side of the side wall to one side of the base, and by other two sides of the side wall to another two of the four side walls. In some examples, the base is oval or circular and the side walls form a generally cylindrical wall extending from the base in a direction normal or perpendicular to the base. In some examples, the side walls have a shape corresponding to one of a square, a rectangle, a trapezoid, a section of a sphere, a section of an ovoid, or a section of an ellipsoid. The opening according to this description should be understood as an opening that provides access to the detergent product included in the box. In some examples, the opening faces the base. In some examples, the opening has a surface area smaller than the surface area of the base. In some examples, the opening has a surface area greater than the surface of the base to provide improved access, for example, by using side walls that extend from the base to an angle of more than 90 degrees from the base. In some examples, the opening is provided after removal of a tamper-proof feature, comprising for example a perforated piece to be removed on first use or a security adhesive that locks the lid to the box or tray. In some examples, the opening is placed in a top panel of the box, the top panel of the box being oriented toward the base of the box, the top panel of the box being separated from the base of the box by at least the walls sides, the top panel of the box being generally coplanar with the base of the box, so the opening covers a part of the top panel, the top panel comprising a peripheral section that surrounds the opening, the peripheral section being a transition piece between a side wall and the opening, for example. In some examples, the opening is rectangular. In some examples, the opening is rectangular with rounded edges. In some examples, the opening is round or oval. The lid according to this description should be understood as an element that allows the opening of the container to be repeatedly closed or opened. In some examples, the lid may be connected to the box, for example by a hinge, or may be separate from the box. The lid according to this description may comprise a top and flanks or flanks of the lid. It should be understood that the top of the lid is intended to cover the opening of the box when the lid is in a closed position. In some examples, the top of the lid is rectangular. In some examples, the top of the lid is round, hexagonal, octagonal or oval, with structures such as round or oval, for example, being approximated by multiplying a series of side panels and flaps of the lid. In some examples, the lid comprises beveled edges. In some examples, the top of the lid is rectangular with rounded edges. It should be understood that although called a "top"', the top of the lid may be placed in different orientations. The lid may comprise flanks. It should be understood that the flanks according to this description are elements connected to the top of the lid and that they extend from the lid to engage one or more side walls of the box. The flanks participate in positioning the top of the lid over the opening. In some examples, the flanks extend perpendicularly from the top of the lid In some examples, the flanks surround a complete perimeter of the top of the lid. In some examples, the flanks partially surround a complete perimeter of the top of the lid, being a portion of the top of the lid without flanks The top of the lid may cover the opening, and at least a portion of the flanks may cover at least a specific portion of the side walls when the lid is in the closed position, the lid being moveable from the closed position to a closed position. open position. The lid movement may be secured 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 participate in satisfying the container's function of storing, transporting, and facilitating access to the contents of the container.

The container according to this description comprises a closure. A closure should be understood in this description as a mechanism that prevents or reduces the probability of accidental opening. The closure according to this description is to maintain the lid in a closed position. It should be understood that the closure according to this description is expected to operate under normal use of the container. It should be understood that the closure may not fulfill its function when, for example, unusual use is made of the box, or when the box is in unusual condition. According to this description, The closure comprises an actuator movable from a locked position to an open position by applying an actuating pressure on the actuator when the lid is in the closed position. The actuator should be understood in this description as a mechanical structure subjected to a movement after actuation by an external force or an actuation pressure, said movement causing the opening of the closure when said movement takes place. In some examples, the actuator according to the present description is elastic and has a default position, said default position corresponding to the lid remaining closed, the elasticity being overcome by an external force or actuation pressure to open the lid. In some examples, the actuator is elastic because the actuator comprises a flexible element, the flexible element having a predetermined position corresponding to the lid being closed, pressing the flexible element to open the lid, the flexible element returning to the predetermined position when it is closed. release pressure. It should be understood that pressure is generated by applying a force to a surface. The actuator according to this description has at least two positions, which are an opening position and a blocking position, so the opening position corresponds to a position that allows the opening of the lid, the blocking position preventing the opening of the lid. lid or reducing the possibility of accidental opening of the lid.

The actuator according to this description may be connected to a specific part of the side walls of the box, which may be a specific part covered by at least a part of the flanks when the lid is in the closed position, the actuator resting against a tab locking of the flanks when in the locked position, the actuator being kept away from the locking tab when in the open position, the actuator being able to be moved by the actuating pressure to an unlocking travel distance in one direction normal to the specific part of the side walls. The connection of the actuator to the specific part of the side wall is due to the actuator participating in locking or unlocking the specific part of the side wall from the part of the flanks that cover the specific part of the side wall, thus allowing release the lid of the box. The flanks may comprise a locking tab. A locking tab should be understood as a mechanical element that interfaces with the actuator. In some examples, the locking tab extends away from the flanks and may be in the form of a projection, ridge, relief, or layer of additional material that adheres to the flanks of the lid and toward the specific portion of the wall. side, so that the actuator can rest against the tongue when in the locking position to avoid separating the specific part of the flank side walls in the area of the actuator. In some examples, the locking tab is included in the flank itself, the locking tab being, for example, formed by an opening in the flanks. The stop according to this description should be understood as a contact between the actuator or part of the actuator and the tongue, said contact preventing the opening of the cover. The actuator is held away from the locking tab when in the open position, to release the locking tab. Said release of the locking tab allows the lid to be opened. The displacement or movement of the actuator from the lock to the open position is by applying to the actuator (directly or indirectly) a pressure or actuating force, such that the actuator moves a distance sufficient to press the contact of the actuator with the locking tab, such distance corresponding to the displacement distance, in a direction normal to the specific part of the side wall. It should be understood that the force or pressure causing the displacement can have a number of different directions, which contributes to the displacement if a component of said force or pressure is in a direction normal to the specific part of the side wall. Said force or pressure may also comprise a component that may be parallel to the side wall. However, actuation is triggered by a component of said force or pressure that is normal to the side wall portion. Said presence of a component normal to the side wall portion participates in the role of the closure of preventing accidental opening by raising the container through the lifting of the lid by applying a force parallel to the side wall, while the desired opening would have place by the consumer “pushing” the actuator and applying the unlocking force or pressure that allows the lid to open. In other words, while a consumer may apply a force to the actuator along a direction that may not be normal to the side wall, if a component of that force is normal to the side wall, that component may participate in the action. application of pressure that leads to displacement.

Said closure would participate in eliminating or reducing the risk of accidental opening of the lid, while allowing the desired opening by a consumer, the operation of such closure depending on ensuring that the actuator remains in contact against the locking tab. even in case of strongly pulling the lid in a direction parallel to the side wall to transport or lift the consumer product. Avoidance or reduction of the risk of accidental opening would also apply to a force that is applied in a direction parallel to the side walls, for example, by friction with another box located side by side with a box according to this description, or by a box that falls during transport, or through internal movements of the contents of the box that pushes the lid during transport. However, strong pulling 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, whereby such bending may produce unwanted uncoupling of the activator locking tab, due to the fact that the actuator is connected to the specific part of the side wall. This would result in an unwanted opening of the lid. Such unwanted opening of the lid may be more likely if the side wall is made of a material such as cardboard used to form the side walls, particularly when the box is a cardboard box.

In some examples, the closure is located in a central area of a side wall of the box. A central area should be understood as substantially equidistant from opposite edges of the side wall in question, said edges being along a direction normal to the base of the box. In such examples, it should be understood that the closure is located closer to an edge of the side wall near the opening than to an edge of the side wall near the base, while being in an area central with respect to the edges normal to base. Said central location of the closure can help prevent the lid of the box from sliding if the box is lifted by holding the lid by applying pressure on the actuator, where said pressure presses the actuator against the structure with a support element in the center, balancing accordingly. This strengthens the forces that maintain the connection between the lid and the box and helps prevent accidental opening. In some examples, the closure may be located on a side wall and between two edges of the side wall, said edges being normal to the base, with the closure being closer to one edge than to the other edge of the two edges, e.g. located closer to the edge by 1/3 of the distance between the two edges. In some examples, a side wall may comprise two closures. In some examples two closures may be provided offset from each other and from a center line to increase the distance separating the two closures. In some examples more than two closures may be provided. In some examples, three closures are provided, for example corresponding to a first closure for a thumb of a user's hand and two other closures on the other side of the cover for an index finger and a middle finger of the same hand of the user, so that this user can operate the three closures with one hand and simultaneously.

The present description aims to resolve this apparent contradiction between, on the one hand, the use of side wall materials that would resist accidental opening and the use of side wall materials that are especially environmentally friendly.

The container may be made of rigid paperboard material, flexible paperboard material, or a mixture thereof. In some examples, the material that forms the box or lid has a wall thickness of more than 220 micrometers and less than 3 mm. In some examples, the material that forms the box or lid has a wall thickness of more than 1 mm and less than 2 mm. In some examples, the material that forms the box or lid is folded back on itself, for example, to reinforce parts or all of the box or lid. The container may be made of paper materials, bio-based material, bamboo fibers, cellulose fibers, cellulose-based or fiber-based materials, or a mixture thereof. The container may be made of materials comprising recycled materials, for example materials based on recycled cellulose fiber.

The lid according to this description actually comprises a structure with a support element, the structure with a support element entering the opening when the lid is in the closed position, at least part of the specific part of the side walls being located between the flanks. and the supporting member structure when the lid is in the closed position, with a distance separating the side walls of the supporting member structure in a direction normal to the specified portion of the side walls when the lid is in the closed position. closed and when no actuation pressure is applied, the separation distance being reduced to zero by flexing the specific portion of the side walls when the actuation pressure is applied above a pressure threshold when the lid is in the closed position. Both the structure with support element and the flanks are structurally part of the lid, allowing the structure with support element and the flanks to intersperse the specific part of the side wall, thus preventing collapse in the specific part of the side wall and unwanted disengagement of the actuator from the locking tab. It is important to take into account the fact that, in the event that actuation pressure is applied while lifting the box using the lid, the applied pressure will engage the specific sandwiched portion of the side wall against the supporting member structure, compensating thereby a force of gravity that would otherwise disconnect the lid from the box, said compensation of the force of gravity being through a resistant static friction force between the specific part of the side wall and the structure with supporting element . In some examples, the use of the support structure allows its use to make the box from a relatively flexible material, where such flexible material would flex in the absence of the support structure to the point that the box would fall. if it were lifted by its cover. Allowing the use of a relatively flexible material also allows the use of a smaller amount of said material because the presence of the structure with a supporting element compensates for said flexibility. The presence of said structure with support element thus prevents or reduces the risk of accidental opening even if the actuation pressure is applied on the closure actuator, for example, when the case is lifted while pressure is applied on the actuator. of the closure.

The structure with support element enters the opening when the lid is in the closed position, fitting inside the box when the lid is in the closed position. Such entry into the opening should be understood as the support structure comprising a part of the support structure that enters the opening when the lid moves from the open to the closed position, and where said part of the structure with supporting element comes out of the opening when the cover is moved from the closed position to the open position. At least part of the specific part of the side walls is located between the flanks and the supporting element structure when the lid is in the closed position. This structure allows the specific part of the side wall to be captured between the flanks and the structure with supporting element, the specific part of the side wall being inserted between the flanks and the supporting element when the cover moves from the open position to the position closed, the specific part of the side wall between the flanks and the structure with supporting element being released when the cover moves from the closed position to the open position. A separation distance separates the side walls of the supporting member structure in a direction normal to the specific portion of the side walls when the lid is in the closed position, said direction corresponding, for example, to a linear edge direction. , and when no drive pressure is applied. Said separation distance would exist on the first side, and would be repeated additionally on a second side of the structure with a support element. Said separation distance allows the insertion of the support element structure through the opening when the lid is closed, so that the support element structure does not collide with the specific part of the side wall when the lid is closed. The gap is reduced to zero by flexing the specific portion of the side walls when the actuation pressure is applied above a pressure threshold when the lid is in the closed position. When said pressure threshold is reached, the side wall is supported against the structure with support element through the separation distance that is reduced to zero, thus preventing the side wall from excessive distortion and preventing it from sinking. at the point on the actuator that releases the locking tab. The separation distance according to this description refers in some examples to a tolerance distance between the lid and the box, which allows the lid to be placed on the box without undue difficulty, while preventing the lid from being loose when in place. the closed position. Although the separation distance according to this description is considered in one region of the closure, the tolerance distance between the lid and the box can be considered along the entire perimeter of the box opening. In some examples, the tolerance is at least 0.1 mm and less than 5 mm. In some examples, the tolerance is at least 1 mm and less than 3 mm. Said tolerance would be measured, for example, when the lid is in the closed position and between an internal surface of the flanks and an external surface of the side walls, understanding that said tolerance may have a different value in a region of the closure.

In some examples, the separation distance is at least 1 mm and less than 1 cm when the lid is in the closed position and no actuation pressure is applied. An interval of this type makes it possible both to facilitate the closing of the lid and to avoid the collapse of the specific part of the side wall which leads to an unwanted unlocking. In some examples, the separation distance is at least 1.5 mm and less than 0.5 cm when the lid is in the closed position and no actuation pressure is applied. In some examples, the separation distance is at least 2 mm and less than 0.4 cm when the lid is in the closed position and no actuation pressure is applied.

In some examples, such as that illustrated in Figure 6, the actuator comprises a flap 603 connected by a hinge portion to a specific portion of the side walls of the box, the flap of the hinge portion extending to a distal edge. of the flap, the hinge portion being located between the flanks and the supporting member structure when the lid is in the closed position, the distal edge extending away from the specific portion of the side walls and resting against the distal edge of the flap. flap against the flank locking tab when in the locking position, the flap being positioned flush against the specified portion of the side walls and the distal edge being kept away from the locking tab when in the open position, the actuation pressure displacing the flap by an acute actuation angle from the closing position to the opening position, the acute angle corresponding to the displacement of the distal edge by the unlocking displacement distance. In some examples, the acute angle is between 5 and 60 degrees. In some examples, the acute angle is between 5 and 45 degrees. In some examples, the acute angle is between 5 and 20 degrees. In some examples, the acute angle is a function of the length of the locking flap in a direction generally parallel to the specific part and of a thickness of the locking tab and of tolerances between the side walls of the case and the flanks of the lid and a tolerance between the side walls of the box and the flap, or patch, as described below. In some examples, the horizontal displacement (along a direction substantially normal to a side wall comprising the specific section) measured at the end of the locking flap that abuts the locking tab is at least a thickness of the locking tab along a direction substantially normal to a side wall comprising the specific section. In some examples, said horizontal displacement is between 0.3 mm and 30 mm. In some examples, a flap length has a length along a direction generally normal to the base of the box greater than the sum of different tolerances comprising a clearance between the locking tab and the flap in the stop area. when the lid is in the closed position and the container is not subjected to external pressure, a tolerance between the flanks of the lid and the side walls of the box, and the tolerance between the side walls of the box and the flap and a deformation by bending the flap. In some examples, the locking flap has a length along a direction generally normal to the base of the case of at least 3 mm and less than 60 mm. In some examples, the locking flap has a length along a direction generally normal to the base of the case of at least 15 mm and less than 45 mm. In some examples, the locking flap has a length along a direction generally normal to the base of the case of at least 25 mm and less than 35 mm. In some examples, the flap has a width along a direction perpendicular to its length and parallel to the specific portion of between 5 mm and 60 mm. Such example width dimensions may allow disengagement of the closure by limiting its width while avoiding a risk of the closure becoming distorted by pressure by providing the closure with a sufficient width. Said sizing selection may depend on the material selected for the different parts that make up the container. Said flap can be used in examples or configurations that differ from those illustrated in Figure 6.

In some examples, not illustrated here, the actuator comprises a patch attached to the specific portion of the side walls. Said patch may be, for example, a piece of material of the same nature as a material used for the manufacture of the box or the lid, said piece of material being, for example, glued to the box, the piece of material being structurally separated from the box, the piece of material acting with the locking tab, the piece of material comprising, for example, a folding line defining a first part that interacts with the locking tab and a second part glued to the box , functioning in this way like the flap described herein.

In some examples, such as that illustrated in Figure 6, the structure 200 with support element comprises a support area, the support area comprising an area of contact with the specific part of the side wall when the gap is reduced to zero by flexing the specific portion of the side walls when the actuation pressure is applied above the pressure threshold when the lid is in the closed position, where the contact area is facing the actuator 603 a along a normal direction towards the specific part of the side walls. Placing said contact area at the level of the actuator allows improving the elasticity of the structure, where the actuation pressure will be absorbed directly by the structure with support element once the separation distance that separates the side walls of the structure with support element support is reduced to zero and the actuator makes direct contact with the structure with supporting element in the contact area.

Illustrative consumer product 600 comprises a closure 610 as illustrated in Figure 6. Consumer product 600 also comprises an additional closure (not illustrated). In fact, in this example and some other examples, the consumer product comprises an additional closure, the additional closure comprising an additional actuator connected to a further specific part of the side walls, the specific part of the side walls being comprised in a first side wall of the box, the additional specific part of the side walls being comprised in a second side wall of the box, the first side wall being opposite the second side wall. The consumer product 600 comprises an actuator 603 of the closure 610 and an additional closure actuator. It should be understood that in this example and in some other examples comprising an additional closure, said additional closure may have a similar or different structure to the closure according to this description. In some examples, the additional closure has a structure corresponding to the structure of the closure according to this description. In some examples, the additional closure has a structure that differs from the structure of the closure according to this disclosure. In some examples, an additional closure according to this description is provided on the same side wall as the closure according to this description. In some examples, an additional closure is provided on a side wall adjacent to the side wall comprising the closure.

In the example illustrated in Figure 6, the flanks of the lid comprise a drive area 210B and a further drive area 210. In fact, in this example and in some other examples, the flanks of the cover comprise an actuation area facing the actuator and which allows the actuator to be moved from the closed position to the open position by applying the actuation pressure in the area. of actuation when the lid is in the closed position, wherein the actuation area comprises one or more of an actuation opening, an actuation flap, an actuation slit or an actuation membrane, wherein the actuation area further comprises an indication visual indicating the location of the actuation area. In the example illustrated in Figures 5 and 6, drive areas 210B and 210 each comprise a drive aperture. The visual indication may be printed on an external surface of the flanks and may comprise one or more arrows or one or more areas printed in a striking color or specific text providing instructions such as "push here to open", for example, or a combination of any of these indications.

In the example illustrated in Figure 6 and in some other examples not illustrated here, the flanks comprise the additional actuation area 210 facing towards the additional actuator and allowing the additional actuator to be moved, the actuation area 210B and the actuation area 210 being additional drive separated by a peripheral path along an outer surface of the lid, the peripheral path measuring less than 20 cm and more than 9 cm. In some examples, this peripheral path is the shortest peripheral path between a top of the drive area and a top of the additional drive area, said top being a point of the respective drive area or additional drive area closest to the top of the lid. In some examples, the peripheral path measures less than 15 cm and more than 11 cm. In some examples, the peripheral path measures less than 14 cm and more than 12 cm. The length of said peripheral path may advantageously allow an adult user to apply a thumb of one hand on the actuator and the index (or middle finger) of the same hand on the additional actuator at the same time to depress both the additional actuator as the additional actuator simultaneously with one hand to unlock the lid and open the lid. In other examples, two closures may be provided on the same side wall, opening taking place by actuating both closures, for example, using both thumbs.

In the illustrative consumer product 600, the drive areas 210B and 210 are spaced in a straight line from the outer surface of the respective flanks where they are located at a distance, where said distance is more than 6 cm and less than 12 cm. . In some examples, the distance is approximately 8 cm. In some examples, the distance is more than 7.5 cm and less than 8.5 cm. In some examples, the distance is more than 8.4 cm and less than 10.4 cm. In some examples, the distance is more than 8.9 cm and less than 9.9 cm. In some examples, the distance is approximately 9.4 cm. In some examples, the separation distances separating the side walls of the supporting member structure are each between 1 mm and 4 mm when no actuation pressure is applied. In some examples, the separation distances are each between 3 mm and 4 mm when no actuation pressure is applied.

In the example illustrated in Figure 6, each closure is separated from a respective gable of the supporting member structure by a separation distance. In this example and in some other examples according to this description, the structure with supporting element comprises an elastic structure in contact at the same time with the specific part and the additional specific part when both the specific part of the first side wall and the additional specific part of the second side wall when the actuation pressure is applied above the pressure threshold both in the actuator and in the additional actuator when the lid is in the closed position. In such a configuration, the elastic structure of the actuator absorbs any excessive pressure applied on the actuators to open the lid. In some examples, the elastic structure, or cardboard structure, is unitary, for example, to facilitate the making. Unitary should be understood to be made from an integral piece of material. In some examples, the elastic structure comprises a plurality of substructures, for example, to facilitate assembly.

In some examples, the flanks of the lid cover approximately 30% of the side walls, 30% in this case corresponding to a relationship between, on the one hand, a height of the flanks in a direction normal to both the top of the lid and the base of the box and, on the other hand, at the height of the side walls in the direction normal to both the top of the lid and the base of the box. In this example, the flanks completely surround the side walls around the opening. Said coverage of the flanks participates in ensuring the placement of the lid, the structural elasticity and the protection of the contents. In some examples, the flanks cover at least 30% of the side walls when the lid is in the closed position. In some examples, the flanks cover at least 35% of the side walls when the lid is in the closed position. In some examples, the flanks cover at least 40% of the side walls when the lid is in the closed position. In some examples, the flanks cover at most 90% of the side walls when the lid is in the closed position. In some examples, the flanks cover at most 80% of the side walls when the lid is in the closed position. In some examples, the flanks cover at most 70% of the side walls when the lid is in the closed position. In some examples, a manufacturing process comprises providing different box sizes, for example, boxes having a side wall height of 10 cm, 11.5 cm, 13.5 cm or 16 cm, whereby each box can be provided with the same lid adjustment for all intended box sizes, such as a lid having a flank height of 7 cm. In some examples, the height of the flank is more than 3 cm. In some examples, the height of the flank is more than 5 cm. In some examples, the height of the flank is more than 6 cm.

The structure with a support element according to this description may comprise a support element located distal to the structure, when the lid is in the closed position at a certain depth. In some examples, the depth is at least 3 mm and less than 50 mm from the top of the cap. In some examples, the depth is at least 5 mm and less than 50 mm from the top of the lid. In some examples, the depth is at least 15 mm and less than 40 mm from the top of the lid. In some examples, the depth is at least 20 mm and less than 35 mm from the top of the lid. The depth of the structure with supporting element participates in reinforcing the structure of the consumer product. A combination of the depth and shape of the supporting member structure, as well as the amount of separation distance, can prevent twisting of the lid.

In some cases, a force is applied to the flanks in a direction normal to the base of the box, in a direction from the base of the box, and toward the top of the lid. Such force can be applied, for example, when the box is lifted off the ground for transport. In such a situation the separation distances separating the side walls of the supporting element structure can be reduced to zero due to the weight of the contents and the box, applying to the locking tabs through the actuators. In such a situation, the structure with a support element makes it possible to avoid accidental opening of the box due to the collapse of the side walls at a point where the actuators would be released from the locking tab, causing the box to fall on the ground, leaving the lid in the hands of the person who lifts the box, holding it by the lid. In this example and some other examples, the detergent product weighs more than 50% of the weight of the consumer product, where a force of gravity produced at the base of the box by the detergent product in the absence of a reaction force at the base of the case produces a bending of the specific portion of the side walls and a reduction to zero of the gap, with the actuator holding the stop against the locking tab when the gap is reduced to zero and when no actuation pressure is applied. In some examples, the detergent product weighs more than 70% of the weight of the consumer product in such a situation. In some examples, the detergent product weighs more than 80% of the weight of the consumer product in such a situation.

In some cases, a force is applied to the actuators in a direction normal to the side walls, in a direction towards the interior of the box, for example, by holding the lid with one hand, a thumb on one side and the other fingers on the other. the other. Such force can be applied, for example, when the box is lifted off the ground for transport. In such a situation, the separation distances may be reduced to zero due to the force sandwiched in the side walls between the supporting member structure and the actuators. In such a situation, the static friction force between the side walls and the structure with the support element prevents accidental opening of the box because the lid is disconnected from the side walls, the box falling to the ground, the lid remaining in place. the hand of the person who lifts the box, holding it by the lid.

In one example, the container is made of cardboard materials and is thus made of materials that can be recycled.
