Abstract

It is disclosed that an example comprises a cardboard support element (100) for a cardboard container, the support element comprising a cardboard structure (101) extending away from a base plane (102) and a first wing (103) connected to the cardboard structure and extending in a direction normal to the base plane (102).

Description

BACKGROUND

[0001] The present invention relates generally to packaging using cardboard material. Cardboard is a widely used packaging material which is particularly suitable for recycling, particularly in a paper recycling stream, and is therefore particularly environmentally friendly, which paper recycling stream can involve a reduced non-fibre content, for example a maximum non-fibre content of 5% by weight. However, cardboard has limitations compared to other packaging materials, such as plastic materials, particularly in terms of mechanical characteristics. BRIEF DESCRIPTION OF DRAWINGS

[0013] Mechanically, cardboard is a relatively flexible material, which means that the walls of a container made of cardboard can offer little resistance to bending under external pressure. In some applications where resistance to bending is important, a material other than cardboard can be used. However, a material other than cardboard can not be directly recyclable. Thus, this material choice leads to certain compromises. It is an object of the present disclosure to propose a cardboard support element for a cardboard container, whereby the inclusion of such a support element in a cardboard container leads to an enhancement of the cardboard structure, allowing the use of cardboard in applications that would otherwise be compromised due to the use of another material.

[0014] Cardboard container designs can achieve enhanced mechanical features by applying separate three-dimensional pieces. Such three-dimensional pieces are to be understood as pieces that are not foldable into a blank shape. Such three-dimensional pieces can be applied into the lid, for example, by gluing. The gluing can occur before or after the lid is formed. When gluing the three-dimensional pieces to a planar structure such as a blank at a supplier site, the transportation from the supplier site can be less efficient due to the three-dimensional nature of the three-dimensional pieces. If such gluing would be performed after transportation from the supplier site, for example, on a production line, gluing the three-dimensional pieces to a blank or inside an erected lid during manufacturing can increase the complexity of the manufacturing operation and slow down the speed of the production line, thereby impacting the productivity of the manufacturing plant. The cardboard support element according to the present disclosure is surprisingly considered as a way of forming a three-dimensional reinforcing structure for a lid that reduces or inhibits the negative impact on the transportation efficiency or the speed of the production line at the manufacturing site. Since the cardboard support element according to the present specification can be shaped using a folding machine that can already be in place at the manufacturing site, little or no additional capital is needed at the manufacturing site to implement the structure according to the present disclosure. In addition to this, the gluing of two two-dimensional structures together, for example, a blank of the support element and a blank of the lid, to form a blank assembly according to the present disclosure, can occur at the supplier facility before transportation to the production facility, where the blank can be erected. The cardboard support according to the present disclosure allows to obtain a rigid lid structure while using a relatively reduced amount of material.

[0015] A cardboard support element according to the present disclosure can be made of the same material as used for a container or lid according to the present disclosure. A support element, lid, box or container according to the present disclosure can be made of a paper or cardboard material, wherein the paper material is for example selected from the group consisting of cardboard, card board, a laminate comprising at least one cardboard or paper layer, cellulose pulp material or mixtures thereof. The material used for manufacturing the support element, lid, box or container can comprise other ingredients such as colorants, preservatives, plasticizers, UV stabilizers, oxygen, flavors, recycled materials and moisture barrier or mixtures thereof. The support element, lid, box or container can comprise an area printed externally or internally. The support element, lid, box or container can be made for example by cardboard manufacturing. Suitable cardboard support element, lid, box or container manufacturing methods can include but are not limited to forming a tube from flat cardboard or paper sheets with a gluing step, folding or mixtures thereof. The cardboard support element, lid, box or container is opaque, for example to protect the content from external light. In some examples, the support element, lid, box or container is at least partially constructed from a paper-based material, and in some specific examples, entirely constructed from a paper-based material. Paper-based material refers herein to a material comprising paper. Without wishing to be bound by theory, “paper” refers herein to a material made from cellulose-based pulp. In some examples, the paper-based material comprises paper, cardboard or mixtures thereof, wherein preferably the cardboard comprises paperboard, corrugated fiberboard or mixtures thereof. Corrugated fiberboard comprises a series of flutes. Each flute can be understood as a channel. The flutes extend parallel to each other, the flute direction being the direction of travel along each channel. The paper-based material can be a laminate comprising paper, cardboard or mixtures thereof, wherein in some examples the cardboard comprises paperboard, corrugated fiberboard or mixtures thereof and at least another material. In some examples, the at least another material comprises a plastic material. In some examples, the plastic material comprises polyethylene, polyethylene terephthalate, polypropylene, polyvinyl alcohol or mixtures thereof. In some examples, the plastic material comprises a copolymer of ethane and ethylene alcohol, or EVOH. A barrier material can be used as the at least another material. The barrier material can be biaxially oriented polypropylene, metallized polyethylene terephthalate or mixtures thereof. The at least another material can comprise a wax, a cellulose material, a polyvinyl alcohol, a silicon dioxide, a casein-based material or mixtures thereof. In some examples, the paper-based laminate comprises a laminate of more than 50 wt%, preferably more than 85 wt% and more preferably more than 95 wt% of a fiber-based material. In some examples, the barrier material can comprise a plastic material having a thickness between 10 micrometers and 40 micrometers. In some examples, the barrier material can comprise a plastic material having a thickness between 10 micrometers and 35 micrometers. The paper-based material can be a laminate.In some examples, the inner surface of the support element, lid, box, or container comprises paper, cardboard, or a mixture thereof, wherein, in particular examples, the cardboard comprises a laminate of paperboard, corrugated fiberboard, and polyethylene, or a mixture thereof, and in some examples, the outer surface of the support element, lid, box, or container, or a combination thereof, comprises at least another material. Alternatively, the at least another material can also be laminated between two layers of paper-based material. Without wishing to be bound by theory, the at least another material can act as a barrier for the paper-based material absorbed leakage liquid facing the inside of the support element, lid, box, or container to prevent or reduce a contamination flow through the walls of the support element, lid, box, or container. It was found that other structures can effectively avoid leakage of the contents or protect the contents from external fluids, for example from showers, sinks, or handling the container or lid with wet hands. Contamination of the walls of the support element, lid, box, or container can be unattractive to the consumer or can contaminate the storage area. In some examples, the support element, lid, box, or container is made of a paper-based material comprising at least another material laminated between two layers of corrugated fiberboard. In some examples, the material for the support element, lid, box, or container comprises a core cardboard flute material sandwiched between two layers of regular cardboard and a polyethylene laminate. The cardboard support element according to the present disclosure can be made of or comprise recycled material or recycled cellulose fibers.

[0016] In some examples, the support element is a plain board support element or a corrugated board support element, whereby the fold line located between the first flap and the cardboard structure is along a direction that takes into account the characteristic direction of the plain board or corrugated board. In some examples, the cardboard support element is a plain board cardboard support element, the plain board having a fiber direction as the characteristic direction, the fiber direction being orthogonal or substantially perpendicular to the fold line and the ridge of the cardboard support element. Such a configuration allows for improved folding behavior of the structure, thereby facilitating the pop-out of the cardboard structure extending away from the base plane. In some examples, the cardboard support element is a corrugated board cardboard support element, the corrugated board comprising parallel grooves having a groove direction defining the characteristic direction of the corrugated board, the groove direction being substantially parallel to the fold line and the ridge of the cardboard support element material of the support element. Such a configuration comprising grooves extending substantially parallel to the fold line can increase the edge-to-edge bending resistance of the board and thus the strength to withstand deformation when pressure is applied along a direction substantially parallel to the groove direction, thereby further increasing the rigidity. In other words, in some examples, the support element is a plain board support element or a corrugated board support element, whereby when the support element is a plain board support element, the fold line located between the first flap and the cardboard structure is substantially perpendicular to the fiber direction of the plain board, and whereby when the support element is a corrugated board support element, the fold line located between the first flap and the cardboard structure is substantially parallel to the groove direction of the corrugated board.

[0017] Figure 1AAn exemplary cardboard support element 100 according to the present disclosure is shown. The support element 100 comprises a cardboard structure 101 extending away from a base plane 102. While the base plane 102 can correspond to e.g. a panel, such as a panel of a container, the base plane 102 can be a theoretical or virtual surface allowing to describe the shape of the support element according to the present disclosure. By extending away from the base plane, it is to be understood that the cardboard structure comprises a support portion coinciding with the base plane and at least a portion extending away from the support portion, the cardboard structure forming a three-dimensional shape, the cardboard material of the cardboard structure defining some boundaries of the three-dimensional shape. In some examples, the cardboard structure comprises a portion separated from the base plane by at least 5 mm. In some examples, the cardboard structure comprises a portion separated from the base plane by at least 10 mm. In some examples, the cardboard structure comprises a portion separated from the base plane 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 cardboard structure comprises a portion separated from the base plane by at least 30 mm. In some examples, the cardboard structure comprises a portion separated from the base plane by at least 35 mm. In some examples, the cardboard structure comprises a portion separated from the base plane by less than 10 cm, e.g. to avoid cantilever situations when the support element is so acting. In some examples, the three-dimensional shape is a portion of a cylinder or a portion of a prism. In Figure 1A In the example shown, the cardboard structure 101 corresponds to a portion of a cylinder. As Figure 1A is shown, the cylinder has a cross-section and an axis. In Figure 1AIn the example shown, the cardboard structure 101 is formed from a single piece of cardboard. The curved shape adopted by the cardboard structure 101 can be due to the cardboard structure being tensioned between other elements, such as parts of the support element or parts of a structure such as a lid in which the support element is located. The cardboard support element 100 comprises a first flap 103. The first flap 103 can be a single flap of the cardboard support element, or the cardboard element can comprise further flaps. A flap should be understood as a piece of cardboard connected to a cardboard structure. The flap can be connected to the cardboard structure by a fold line, in which case the support element can be made from a single piece of cardboard. The flap can be connected to the cardboard structure by a segment, for example a fold line, parallel to an axis of a cylinder or prism corresponding to the cardboard structure, the axis of the cylinder or prism being parallel to the base plane. The flap can be connected to the cardboard structure by a glue joint. The flap can be integral with the cardboard structure, or a separate piece from the cardboard structure, while connected to the cardboard structure to form the support element. The flap according to the present disclosure extends in a direction orthogonal to the base plane. Orthogonal or perpendicular should be understood in this specification as substantially orthogonal or substantially perpendicular. In some examples, orthogonal or perpendicular comprises an angle of less than 120 degrees and greater than 60 degrees. In some examples, orthogonal or perpendicular comprises an angle of less than 110 degrees and greater than 70 degrees. In some examples, orthogonal or perpendicular comprises an angle of less than 110 degrees and greater than 70 degrees. In some examples, orthogonal or perpendicular comprises an angle of less than 100 degrees and greater than 80 degrees. In some examples, orthogonal or perpendicular comprises an angle of less than 95 degrees and greater than 85 degrees. The first flap 103 forms, for example, an angle 104 of 90 degrees with the base plane 102.

[0018] Cardboard support elements according to the present disclosure are intended to provide mechanical support to a cardboard wall, for example a cardboard wall of a container or a lid of a container, which rests against the support element if subjected to a force or pressure.

[0019] Figure 1B Another example cardboard support element 110 is shown, comprising a cardboard structure 111 extending away from a base plane 112 and a first flap 113 connected to the cardboard structure 111, the first flap 113 extending in a direction orthogonal to the base plane 112. In Figure 1BIn this example, the cardboard structure corresponds to a portion of a prism, more specifically a portion of a triangular prism, when the base plane 112 is taken into account. In this example, the support element comprises a second flap 115, which in this example is connected to the cardboard structure 111 and extends in a direction parallel to the base plane, which in this example coincides with the base plane. In this example, the cardboard structure 111 comprises a first main panel 116 and a second main panel 117, which correspond to a first face and a second face of the prism, respectively, connected by a linear ridge 118, which corresponds to an edge of the prism connecting the first face and the second face, the first main panel 116 and the second main panel 117 preferably forming an angle with the base plane of more than 15 degrees. In this case, the main panels form an angle of about 30 degrees with the base plane 116. In this example, the first flap 113 is directly connected to the first main panel 116, and the second flap 115 is directly connected to the second main panel 117. In some examples, the ridge is separated from the base plane by at least 5 mm. In some examples, the ridge is separated from the base plane by at least 10 mm. In some examples, the ridge is separated from the base plane by at least 15 mm. In some examples, the ridge is separated from the base plane by at least 20 mm. In some examples, the ridge is separated from the base plane by at least 30 mm. In some examples, the ridge is separated from the base plane by at least 35 mm. In some examples, the ridge is separated from the base plane by less than 10 cm, for example to avoid cantilevered situations when the support element is so acting.

[0020] Figure 1C Another example cardboard support element 120 is shown, which comprises a cardboard structure 121 extending away from a base plane 122 and a single first flap 123 connected to the cardboard structure 121, which extends in a direction orthogonal to the base plane 122. In this example, the cardboard structure corresponds to a portion of a prism, more specifically a portion of a quadrangular prism, when the base plane 122 is taken into account. Figure 1C

In this example, the cardboard structure corresponds to a portion of a prism, more specifically a portion of a triangular prism, when the base plane 132 is taken into account. Figure 1D ​In this example, the cardboard structure corresponds to a portion of a prism, more specifically a portion of a pentagonal prism, when the base plane 132 is taken into account. In this example, the support element comprises a second flap 135 connected to the cardboard structure 131 in this example and extending in a direction normal to the base plane. In this example, the cardboard structure 131 comprises a first main panel 136 and a second main panel 137 corresponding to a first face and a second face of the prism respectively, connected by a linear ridge 138 corresponding to an edge of the prism connecting the first face and the second face. In this example, the support element further comprises a first secondary panel 139 connecting the first flap 133 and the first main panel 136, and a second secondary panel 140 connecting the second flap 135 and the second main panel 137, whereby a fold line separates the first flap 133 from the first secondary panel 139, the first secondary panel 139 from the first main panel 136, the first main panel 136 from the second main panel 137, the second main panel 137 from the second secondary panel 140, and the second secondary panel 140 from the second flap 135, the fold line being parallel to the linear ridge 138 which is itself parallel to the axis of the prism. In this example, the first flap 133 is indirectly connected to the first main panel 136 through the first secondary panel 139, and the second flap 135 is indirectly connected to the second main panel 137 through the second secondary panel 140.

[0022] It will be appreciated that features of the various examples described herein, such as the number of flaps, the orientation of the flaps, the number and angle of the panels, can be combined to produce alternative examples.

In this example, the cardboard structure 201 comprises a first main panel 204 and a second main panel 205 connected by a linear ridge 206, the first main panel 204 and the second main panel 205 corresponding to a first face and a second face of a prism respectively, the ridge 206 corresponding to an edge of the prism connecting the first face and the second face. In this example, the support element further comprises a first secondary panel 207 connecting the first flap 203 and the first main panel 204, and a second secondary panel 208 connecting the second main panel 205, whereby a fold line separates the first flap 203 from the first secondary panel 207, the first secondary panel 207 from the first main panel 204, the first main panel 204 from the second main panel 205, and the second main panel 205 from the second secondary panel 208, the fold line being parallel to the linear ridge 206 which is itself parallel to the axis of the prism. In this example, the first flap 203 is indirectly connected to the first main panel 204 through the first secondary panel 207, and the second main panel 205 is indirectly connected to the second secondary panel 208. Figure 2In this example, the cardboard structure 201 corresponds to a portion of a prism, more specifically a portion of a tri-prism, when the base plane 202 is taken into account. In this example, the support element comprises a second flap 205, which in this example is connected to the cardboard structure 201 and extends in a direction orthogonal to the base plane 202. In this example, the cardboard structure 201 comprises a first main panel 206 and a second main panel 207, which respectively correspond to a first face and a second face of the prism, connected by a linear ridge 208, which corresponds to an edge of the prism connecting the first face and the second face. In this example, the support element further comprises a first secondary panel 209, which indirectly connects the first flap 203 and the first main panel 206, and a second secondary panel 210, which indirectly connects the second flap 205 and the second main panel 207. In this example, the support element 200 further comprises a first tertiary panel 211, which directly connects the first flap 203 and the first secondary panel 209, and a second tertiary panel 212, which connects the second flap 205 and the second secondary panel 210, whereby the fold lines separate the first flap 203 from the first tertiary panel 211, the first tertiary panel 211 from the first secondary panel 209, the first secondary panel 209 from the first main panel 206, the first main panel 206 from the second main panel 207, the second main panel 207 from the second secondary panel 210, the second secondary panel 210 from the second tertiary panel 212, and the second tertiary panel 212 from the second flap 205, the fold lines being parallel to the linear ridge 208, whereby the first secondary panel and the second secondary panel each form an angle of 0 to 10 degrees with the base plane, and whereby the first tertiary panel and the second tertiary panel each preferably form an angle of more than 15 degrees with the base plane. In this particular example, the first secondary panel 209 and the second secondary panel 210 are parallel to the base plane 202.

[0024] Figure 3 A lid 300 of a cardboard container containing a detergent product is shown, the lid 300 comprising a support element. While the support element can be any support element according to the present specification, the lid 300 is here shown as having a support element according to the example of Fig. 1. Figure 2The support element 200 is shown. For a clear view of the support element 200, the lid 300 is shown upside down. In this example, the lid is shown as comprising a single support element according to the present disclosure. However, a lid according to the present disclosure can comprise one or more additional support elements. The use of one or more additional support elements can allow for a saving of material while obtaining the effect of a support element on different sides of the lid. The use of a single support element can allow for compensating for opposing forces on opposite sides of the lid on the single support element. In a preferred embodiment, a single support element is used, the use of a single support element reduces manufacturing complexity. In another preferred embodiment, two support elements are used on a single lid, the two support elements are placed against opposite side flaps, the two support elements are substantially parallel to each other, the two support elements have respective apexes which can be aligned or can correspond to different relative positions, the respective apexes are preferably aligned to correspond to the position of the fingers of a consumer gripping the lid. The use of two support elements has the advantage that less material can be used than with a single support element, whereby the two support elements can be separated by a gap between the two support elements.

[0025] The lid 300 comprises a top 301 (shown here at the bottom as the lid is upside down to provide a good view of the support element) and side flaps 302-305, the top 301 being parallel to the base plane 202, a first flap 203 being fixed to a first one of the side flaps 302, the support element 200 comprising a second flap 205 connected to the cardboard structure 201 and extending in a direction normal to the base plane 202. The second flap can also be parallel to the base plane 202. The second flap is fixed to a second one of the side flaps, the first side flap being opposite the second side flap. The second flap can alternatively be fixed to the top. In this and other examples, it should be noted that when the lid is in the closed position and placed on top of the container, the side wall of the container will be inserted against the first flap, thereby participating in the rigidity of the entire assembly formed by the container closed by the lid.

[0026] Figure 4 A consumer product 400 is shown comprising a detergent product (not shown) and a container comprising a box 401 and a lid such as the lid 300 comprising a support element according to the present disclosure, the box 401 comprising a lock 402 to hold the lid 300 in the closed position, the lock 402 comprising an actuator 403 which is aligned with a portion of the cardboard structure 201 when the lid 300 is in the closed position, the cardboard structure 201 fitting inside the box 401 when the lid 300 is in the closed position.

[0027] Detergent products are potentially relatively heavy products, for example when a container for such a product is carrying the full weight of such a detergent product, particularly when the consumer product is newly purchased and thus contains a large amount of detergent product. While some consumers can lift and transport such a consumer product by holding the base of a box containing such a detergent product, such lifting and transporting can also be performed by holding such a consumer product with the lid, without holding the base. In such cases, the lid, which is subjected to the weight of the detergent product, can be released and open the box, which falls and can spread its contents. Such situations should be avoided. In addition to avoiding such inadvertent lid unlocking, the structure of the consumer product container should maintain or improve the ergonomics of opening, and prevent or reduce permanent sidewall deformation upon excessive or repeated application of force to the consumer product, for example during transport, against other objects in a grocery shopping bag, when subjected to external pressure, or when dropped. At the same time, the container can be crafted so as to protect the environment. Consumer products according to the present disclosure aim to take into account these different aspects.

[0028] In the present disclosure, consumer product should be understood as a product that is provided to an end consumer. Such a consumer product can for example be purchased at a supermarket, the end consumer can store such a consumer product at home. The consumer product can be provided in large quantities, and thus environmental concerns should be taken into account at the time of design. The design of the consumer product should also take into account the problem of transport to the retail store. The design of the consumer product should also take into account the shelf storage at the retail store. The design of the consumer product should also take into account the transport from the retail store to the home of the consumer. The design of the consumer product should also take into account the storage at the home of the private end consumer. The design of the consumer product should also take into account the use of the consumer product at the home of the private end consumer. The design of the consumer product should also take into account the disposal.

[0029] The consumer product according to the present disclosure comprises a detergent product. A detergent product should be understood in the present disclosure as a product comprising a surfactant. The detergent product can also comprise a bleach or other ingredients. Exemplary detergent product compositions are described in more detail herein. In some examples, the detergent product comprises a unit dose detergent pouch, preferably a water-soluble unit dose detergent pouch, more preferably a flexible water-soluble unit dose detergent pouch. Exemplary unit dose detergent pouches are described in more detail herein.

[0030] A consumer product according to the present disclosure also includes a container. In the present disclosure, a container is understood to be an object that contains a content, for example in a cavity of the container. The container facilitates the protection, transport, storage, access and handling of the consumer product. In the present disclosure, a container includes a box. A box is understood to be a generally parallelepiped, barrel-shaped, cylindrical, circular, oval or cuboid three-dimensional object that defines a cavity. The use of a parallelepiped box can facilitate storage and transport by allowing the boxes to be stacked in a space-efficient manner. In some examples, the box can be a parallelepiped provided with some rounded, tapered trapezium or beveled edges. A box according to the present disclosure includes a detergent product. It is understood that the detergent product is contained or stored in the box. A box according to the present disclosure can include a base, a side wall and an opening. A base according to the present disclosure is understood to be a surface on which the box can be located when placed on a support surface such as a shelf or a floor. In some examples, the base is flat. In some examples, the base is rectangular. In some examples, the base is oval or circular. In some examples, the base is flat. In some examples, the base has an embossed profile that protrudes inwardly or outwardly in the form of a relief. A side wall according to the present disclosure is understood to extend from the base and to connect the base to the opening, a transition piece or a lid. It is understood that the connection of the base to the opening can also include a transition piece in addition to the side wall. For example, the transition piece can be glued or otherwise attached to the side wall. In some examples, the side wall is perpendicular to the base. In some examples, the base is rectangular and has four edges, four side walls extend perpendicularly from the base, each side wall is rectangular, each side wall is connected to an edge of the base by a side wall edge and to another two of the four side walls by another two side wall edges. In some examples, the base is oval or circular and the side wall forms a generally cylindrical wall extending from the base in a direction normal or perpendicular to the base. In some examples, the side wall has a shape corresponding to one of a square, a rectangle, a trapezium, a segment of a sphere, a segment of an oval or a segment of an ellipsoid. An opening according to the present disclosure is understood to be an orifice that provides access to the detergent product contained in the box. In some examples, the opening faces the base. In some examples, the opening has a surface that is smaller than the surface of the base. In some examples, the opening has a surface that is larger than the surface of the base in order to provide, for example, an improved access using a side wall that extends from the base at an angle greater than 90 degrees from the base. In some examples, the opening is provided after removal of a tamper proof feature, for example a perforation to be removed at first use or a tamper evident label that locks the lid to the box or tray.In some examples, the opening is placed on a top panel of the box, the top panel of the box facing the base of the box, the top panel of the box being separated from the base of the box by at least the side walls, the top panel of the box being substantially coplanar with the base of the box, whereby the opening covers a portion of the top panel, the portion of the top panel comprising a perimeter section around the opening, the perimeter section being for example a transition between the side walls and the opening. In some examples, the opening is rectangular. In some examples, the opening is rectangular with rounded edges. In some examples, the opening is circular or elliptical. A lid according to the disclosure should be understood as an element allowing to repeatedly close or open the opening of the container. In some examples, the lid can be connected to the box, for example by a hinge, or can be separate from the box. A lid according to the disclosure can comprise a top and flanks. 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 circular, hexagonal, octagonal or elliptical. 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 named “top”, the top of the lid can be positioned along different orientations. The lid can comprise flanks. It should be understood that a flank according to the disclosure is an element connected to the top of the lid and extending from the lid in order to engage one or more side walls of the box. The flanks participate in placing the top of the lid on the opening. In some examples, the flanks extend perpendicularly from the top of the lid. In some examples, the flanks surround the entire perimeter of the top of the lid. In some examples, the flanks partially surround the entire perimeter of the top of the lid, a portion of the top of the lid being free of flanks. When the lid is in a closed position, the top of the lid can cover the opening and at least a portion of the flanks can cover at least a certain portion of the side walls, the lid being able to move from the closed position to an open position. The movement of the lid can be constrained by a connection with the box, such as a hinge, or can be completely removable, for example to provide improved access to the contents of the box. The box and the lid cooperate to participate in the roles of storing, transporting and facilitating access to the contents of the container.

[0031] The container according to the present disclosure comprises a lock. In the present disclosure, a lock is to be understood as a mechanism that prevents or reduces the likelihood of accidental opening. The lock according to the present disclosure keeps the lid in a closed position. It is to be understood that the lock according to the present disclosure is intended to function under normal use of the container. It is to be understood that the lock can not fulfil its function when the box is used unusually, or when the box is in unusual conditions. According to the present disclosure, the lock comprises an actuator that is able to move from a locked position to an open position by exerting an actuation pressure on the actuator when the lid is in a closed position. In the present disclosure, an actuator is to be understood as a mechanical structure that is subjected to a movement upon actuation by an external force or actuation pressure, when such movement occurs, such movement results in the opening of the lock. In some examples, the actuator according to the present disclosure is resilient and has a default position that corresponds to the lid being kept closed, this resilience being overcome by the external force or actuation pressure in order to open the lid. In some examples, the actuator is resilient in that it comprises a flexible element that has a default position that corresponds to the lid being kept closed, this flexible element being pressed to open the lid, the flexible element springing back to the default position when the pressure is released. It is to be understood that a pressure is generated by exerting a force on a surface. The actuator according to the present disclosure has at least two positions, namely an open position and a locked position, whereby the open position corresponds to a position that allows the lid to be opened, the locked position prevents the lid from being opened or reduces the likelihood of the lid being opened accidentally.

[0032] An actuator according to the disclosure can be connected to a specific portion of the side wall of the cartridge, which specific portion can be the specific portion covered by at least a portion of the side wing when the lid is in the closed position, the actuator abutting against a locking tab of the side wing when in the locked position, the actuator remaining away from the locking tab when in the open position, the actuator being displaceable under the action of an actuation pressure in a direction normal to the specific portion of the side wall by an unlocking displacement distance. The connection of the actuator to this specific portion of the side wall is due to the participation of the actuator in locking or unlocking this specific portion of the side wall from the portion of the side wing covering this specific portion of the side wall, thus allowing the release of the lid from the cartridge. The side wing can comprise a locking tab. The locking tab is understood as a mechanical element interlocking with the actuator. In some examples, the locking tab extends away from the side wing and can be in the form of a bump, a ridge, an embossment or an additional layer of material protruding from the side wing of the lid and towards the specific portion of the side wall, so that the actuator, when in the locked position, can abut against the tab to prevent the separation of the specific portion of the side wall from the side wing in the area of the actuator. In some examples, the locking tab is contained in the side wing itself, the locking tab being formed for example by an aperture in the side wing. The abutment according to the disclosure is understood as the contact between the actuator or a portion of the actuator and the tab, this contact preventing the opening of the lid. This actuator remains away from the locking tab in order to release the locking tab when in the open position. This release of the locking tab allows the opening of the lid. The displacement or movement of the actuator from the locked position to the open position is by the application of an actuation pressure or force on the actuator (directly or indirectly) such that the actuator is displaced in a direction normal to the specific portion of the side wall by a distance sufficient to inhibit the contact of the actuator with the locking tab, this distance corresponding to the displacement distance. It is understood that the force or pressure leading to this displacement can have a plurality of different directions, different directions being conducive to the displacement if a component of such force or pressure is in a direction normal to the specific portion of the side wall. Such force or pressure can also comprise a component parallel to the side wall. However, the displacement is triggered by the component of such force or pressure normal to the portion of the side wall. The presence of such a component normal to the portion of the side wall participates in the action of the locking, i.e. by applying a force parallel to the side wall to lift the lid to lift the container so as to avoid accidental opening, while the desired opening will occur by the consumer "pushing" the actuator and applying an unlocking force or pressure allowing the opening of the lid. In other words, while the consumer can apply a force on the actuator in a direction that can not be normal to the side wall, if a component of such force is normal to the side wall, such component can participate in the application of the pressure leading to the displacement.

[0033] Such a locking will participate in inhibiting or reducing the risk of accidental opening of the lid, while allowing the desired opening by the consumer, the function of such a locking depending on ensuring that the actuator remains abutting against the locking tab even in case of a strong pulling of the lid in a direction parallel to the side wall, for example in order to transport or lift the consumer good. Avoiding or reducing 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 positioned side by side with the box according to the disclosure, or by tipping of the box during transport, or by internal movement of the content of the box pushing the lid during transport. However, a strong pulling in a direction parallel to the side wall can affect the structure of the side wall (for example, cause the side wall to bend), whereby such a bending can create an undesired disengagement of the locking tab from the actuator due to the specific portion of the side wall to which the actuator is connected. This would lead to an undesired opening of the lid. Such an undesired opening of the lid can be more likely if the side wall is made of a material such as the cardboard used to form the side wall, in particular when the box is a cardboard box.

[0034] In some examples, the locking is placed in a central region of the side wall of the box. The central region should be understood as being substantially equidistant from the opposite edges of the relevant side wall, such edges being along a direction orthogonal to the base of the box. In such examples, it should be understood that the locking is positioned closest to the edge of the side wall that is proximal to the opening rather than the edge of the side wall that is proximal to the base, while being in a central region with respect to the edge orthogonal to the base. Such a central position of the locking can contribute to avoiding the lid from slipping off the box if the box is lifted by holding the lid with a pressure exerted on the actuator, whereby such a pressure presses the actuator against the center of the support element, thereby balancing the force that maintains the connection between the lid and the box, and contributing to avoid accidental opening. In some examples, the locking can be located on the side wall and between two edges of the side wall, such edges being orthogonal to the base, the locking being closer to one of the two edges than to the other, for example being positioned at 1 / 3 of the distance between the two edges closer to one edge. In some examples, one side wall can comprise two lockings.

[0035] The disclosure aims at solving, in one aspect, the apparent contradiction between the use of a material for the side wall that will resist accidental opening and the use of a particularly environmentally friendly material for the side wall.

[0036] The container can be made of rigid cardboard material, flexible cardboard material, or a mixture thereof. In some examples, the material forming the box or the lid has a wall thickness greater than 300 microns and less than 3 mm. In some examples, the material forming the box or the lid has a wall thickness greater than 1 mm and less than 2 mm. In some examples, the material forming the box or the lid is folded on itself, for example to reinforce part or all of the box or the lid. The container can be made of paper material, bio-based material, bamboo fiber, cellulose fiber, cellulose-based or fiber-based material, or a mixture thereof. The container can be made of a material comprising recycled material, for example recycled cellulose fiber-based material.

[0037] The lid according to the disclosure also actually comprises a support element which enters the opening when the lid is in the closed position, at least a portion of the particular portion of the side wall being located between the side wing and the support element when the lid is in the closed position, the gap distance separating the side wall from the support element in a direction normal to the particular portion of the side wall when the lid is in the closed position and no actuation pressure is applied, the gap distance being reduced to zero by flexing of the particular portion of the side wall when the applied actuation pressure is higher than the pressure threshold when the lid is in the closed position. Both the support element and the side wing are structurally part of the lid, the support element and the side wing allowing to sandwich the particular portion of the side wall, preventing it from sinking and the actuator from undesirably disengaging from the locking tab. It is important to note the fact that in case of actuation pressure applied by lifting the box with the lid, the applied pressure will make the sandwiched particular portion of the side wall rest on the support element, thus compensating the gravity which would otherwise cause the lid to disconnect from the box, this compensation of gravity being achieved by the resistance to static friction between the particular portion of the side wall and the support element. In some examples, the use of a support element allows to use a relatively flexible material to manufacture the box, whereby without the support element such a flexible material would flex to such an extent that the box would fall if lifted with its lid. The allowance to use a relatively flexible material also allows to use a lesser amount of such material, as there is a support element compensating for such flexibility. The presence of such a support element thus prevents or reduces the risk of accidental opening even if actuation pressure is applied to the actuator of the locking piece, for example when the box is lifted while pressure is applied on the actuator of the locking piece.

[0038] In some examples, the support element can be made of the same material as the material used to manufacture the top of the lid. In some examples, the support element is made of a different material than the material used for the top of the lid. The support element enters the opening when the lid is in the closed position. This entry into the opening is to be understood as the support element comprising a support element portion that enters the opening when the lid moves from the open position to the closed position, and from which this support element portion exits the opening when the lid moves from the closed position to the open position. At least a portion of this particular portion of the side wall is located between the side wing and the support element when the lid is in the closed position. This structure allows to capture this particular portion of the side wall between the side wing and the support element, when the lid moves from the open position to the closed position, this particular portion of the side wall being inserted between the side wing and the support element, when the lid moves from the closed position to the open position, this particular portion of the side wall being released from between the side wing and the support element. A gap distance separates the side wall from the support element in a direction normal to the particular portion of the side wall when the lid is in the closed position, and this direction corresponds for example to the direction of the linear ridge when no actuation pressure is applied. This gap distance will exist on a first side of the support element, and is otherwise repeated on a second side of the support element. This gap distance allows the support element to be inserted through the opening when the lid is closed, so that the support element does not collide with the particular portion of the side wall when the lid is closed. When the lid is in the closed position, the gap is reduced to zero by flexion of this particular portion of the side wall when the applied actuation pressure is higher than a pressure threshold. When this pressure threshold is reached, the side wall rests on the support element by a gap distance reduced to zero, thus preventing the side wall from deforming too much and preventing the side wall from sinking to the position where the actuator releases the locking tab. The gap distance according to the disclosure involves, in some examples, a tolerance distance between the lid and the box that allows the lid to be placed on the box without excessive difficulty, while avoiding the lid from coming loose when it is in the closed position. While the gap distance according to the disclosure is considered in a certain region of the locking piece, the tolerance distance between the lid and the box can be considered along the entire perimeter of the opening of the box. In some examples, this tolerance is at least 0.1 mm and less than 5 mm. In some examples, this tolerance is at least 1 mm and less than 3 mm. This tolerance is measured for example between the inner surface of the side wing and the outer surface of the side wall when the lid is in the closed position, it being understood that this tolerance can take different values in the region of the locking piece.

[0039] In some examples, the gap 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. This range allows for easy closure of the lid and prevents certain portions of the sidewall from sagging that can lead to unwanted unlocking. In some examples, the gap 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 gap 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.

[0040] In some examples, for example as Figure 4As shown, the actuator includes a flap 403 connected by a hinge portion to a particular portion of the side wall of the box, the flap extending from the hinge portion to a distal edge of the flap, the hinge portion being located between the side wing and the support element when the lid is in the closed position, the distal edge extending away from the particular portion of the side wall and the distal edge of the flap abutting against the locking tab of the side wing when in the locked position, the flap lying flush against the particular portion of the side wall and the distal edge remaining away from the locking tab when in the open position, the actuation pressure displacing the flap from the closed position by an acute actuation angle to the open position, the acute angle corresponding to a displacement of the distal edge by an 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 substantially parallel to the particular portion and a function of the thickness of the locking tab and a function of the tolerance between the side wall of the box and the side wing of the lid and a function of the tolerance between the side wall of the box and the flap or patch as described below. In some examples, the horizontal displacement (along a direction substantially orthogonal to the side wall including the particular section) measured at the end of the locking flap that abuts against the locking tab is at least the thickness of the locking tab along a direction substantially orthogonal to the side wall including the particular section. In some examples, such horizontal displacement is between 0.3 mm and 30 mm. In some examples, the length of the flap has a length along a direction substantially orthogonal 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 region when the lid is in the closed position and the container is not subject to external pressure, the tolerance between the side wing of the lid and the side wall of the box, and the tolerance between the side wall of the box and the flap and the flexural deformation of the flap. In some examples, the locking flap has a length along a direction substantially orthogonal to the base of the box of at least 3 mm and less than 60 mm. In some examples, the locking flap has a length along a direction substantially orthogonal to the base of the box of at least 15 mm and less than 45 mm. In some examples, the locking flap has a length along a direction substantially orthogonal to the base of the box of at least 25 mm and less than 35 mm. In some examples, the flap has a width along a direction orthogonal to its length and parallel to the particular portion of between 5 mm and 60 mm. Such example width dimensions can allow for easy disengagement of the locking by limiting its width while avoiding the risk of deformation of the locking due to pressure by providing it with sufficient width. Such dimensional choices can depend on the materials chosen for forming the different portions of the container. Such flap can be used in examples or configurations other than Figure 4 the examples shown.

[0041] In some examples not shown here, the actuator comprises a patch glued to a specific portion of the side wall. Such a patch can for example be a piece of material of the same nature as the material used to manufacture the box or the lid, such a piece of material being for example glued to the box, such a piece of material being structurally separate from the box, such a piece of material interacting with the locking tab, such a piece of material comprising for example a fold line defining a first portion interacting with the locking tab and a second portion glued to the box, thereby acting as a flap as described herein.

[0042] In some examples such as Figure 4 In some examples shown here, the support element 200 comprises a support region comprising a region in contact with the specific portion of the side wall when the gap is reduced to zero by flexion of the specific portion of the side wall when the actuation pressure is applied above the pressure threshold when the lid is in the closed position, whereby the contact region faces the actuator 403 along a direction normal to the specific portion of the side wall. Having such a contact region at the level of the actuator allows to increase the elasticity of the structure, whereby once the gap distance separating the side wall from the support element is reduced to zero and the actuator is in direct contact with the support element at the contact region, the actuation pressure will be directly absorbed by the support element.

[0043] The example consumable 400 comprises a lock 402 as Figure 4 The consumable 400 further comprises an additional lock (not shown). Indeed, in this example and in some other examples, the consumable comprises an additional lock comprising an additional actuator connected to an additional specific portion of the side wall, the specific portion of the side wall being comprised in a first side wall of the box, the additional specific portion of the side wall being comprised in a second side wall of the box, the first side wall being opposite to the second side wall. The consumable 400 comprises the actuator 403 of the lock 402 and an additional actuator of the lock. It should be understood that in this example and in some other examples comprising an additional lock, such an additional lock can have a structure similar or different from the lock according to the disclosure. In some examples, the additional lock has a structure corresponding to the structure of the lock according to the disclosure. In some examples, the additional lock has a structure different from the structure of the lock according to the disclosure. In some examples, the additional lock is provided on the same side wall as the lock according to the disclosure. In some examples, the additional lock is provided on a side wall adjacent to the side wall comprising the lock.

[0044] In Figure 4In the illustrated example, the side wing of the lid includes an actuation region 404 and an additional actuation region 405. Indeed, in this example and in some other examples, the side wing of the lid includes an actuation region that faces the actuator and that, when the lid is in the closed position, allows the actuator to be displaced from the closed position to the open position by applying an actuation pressure at the actuation region, whereby the actuation region comprises one or more of an actuation aperture, an actuation tab, an actuation slit, or an actuation diaphragm, whereby the actuation region further comprises a visual indication that indicates the location of the actuation region. In Figure 4 and Figure 9A In the illustrated example, the actuation regions 404 and 405 each comprise an actuation aperture. The visual indication can be printed on the outer surface of the side wing and can comprise one or more arrows or one or more areas printed in a prominent color or specific text that provides an indication, such as “push here to open”, or a combination of any of these indications.

[0045] In Figure 4 In the illustrated example and in some other examples not illustrated here, the side wing includes an additional actuation region 405 that faces and allows the displacement of an additional actuator, the actuation region 404 and the additional actuation region 405 being separated along a perimeter path of the outer surface of the lid that measures less than 20 cm and more than 9 cm. In some examples, this perimeter path is the shortest perimeter path between the top of the actuation region and the top of the additional actuation region, such a top being the point of the respective actuation region or additional actuation region that is closest to the top of the lid. In some examples, the perimeter path measures less than 15 cm and more than 11 cm. In some examples, the perimeter path measures less than 14 cm and more than 12 cm. The length of such a perimeter path can advantageously allow an adult user to apply the thumb of one hand on the actuator while applying the index finger (or the middle finger) of the same hand on the additional actuator, in order to press both the actuator and the additional actuator with one hand, thereby unlocking and opening the lid. In other examples, the two locking pieces can be provided on the same side wall, the two locking pieces being actuated by, for example, using two thumbs.

[0046] In the example consumable 400, the actuation regions 404 and 405 are separated from the outer surface of the respective flanks in which they are located by a straight line by a distance, whereby such distance is greater than 6 cm and less than 12 cm. In some examples, the distance is about 8 cm. In some examples, the distance is greater than 7.5 cm and less than 8.5 cm. In some examples, the distance is greater than 8.4 cm and less than 10.4 cm. In some examples, the distance is greater than 8.9 cm and less than 9.9 cm. In some examples, the distance is about 9.4 cm. In some examples, the gap distance separating the side walls from the support element is each between 1 mm and 4 mm when no actuation pressure is applied. In some examples, the gap distance is each between 3 mm and 4 mm when no actuation pressure is applied.

[0047] In Figure 4 In the example shown, each lock is separated from the respective chevron of the support element by a gap distance. In this example and in some other examples according to the present disclosure, the support element comprises a resilient structure that is in contact with both the particular portion of the first side wall and the additional particular portion of the second side wall simultaneously when the resilient structure is flexed upon both the particular portion and the additional particular portion when the actuation pressure applied on both the actuator and the additional actuator is above the pressure threshold while the lid is in the closed position. In this configuration, the resilient structure of the actuator absorbs any excess pressure applied on the actuator in order to open the lid. In some examples, the resilient structure or the cardboard structure is unitary, for example to facilitate manufacturing. Unitary is to be understood as made from a single piece of material. In some examples, the resilient structure comprises a plurality of sub-structures, for example to facilitate assembly.

[0048] In some examples, the side wings of the lid cover about 30% of the side walls of the box, in which case 30% corresponds to the ratio between, on the one hand, the height of the side wings in a direction orthogonal to both the top of the lid and the base of the box, and, on the other hand, the height of the side walls in a direction orthogonal to both the top of the lid and the base of the box. In one example, the side wings completely surround the side walls around the opening. This coverage of the side wings participates in ensuring the placement, structural resilience and protection of the contents of the lid. In some examples, the side wings cover at least 30% of the side walls when the lid is in the closed position. In some examples, the side wings cover at least 35% of the side walls when the lid is in the closed position. In some examples, the side wings cover at least 40% of the side walls when the lid is in the closed position. In some examples, the side wings cover at most 90% of the side walls when the lid is in the closed position. In some examples, the side wings cover at most 80% of the side walls when the lid is in the closed position. In some examples, the side wings cover at most 70% of the side walls when the lid is in the closed position. In some examples, the 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 suitable for all provided box sizes, such as a lid having a side wing height of 7 cm. In some examples, the side wing height exceeds 3 cm. In some examples, the side wing height exceeds 5 cm. In some examples, the side wing height exceeds 6 cm.

[0049] Figure 5 An exemplary planar support element blank 500 according to the present disclosure is shown, in this case corresponding to the support element 300. The blank 500 comprises a first flap 203, a first main panel 206, a second main panel 207 and a second flap 205, which are successively joined to each other in the following order, each flap or panel being separated from the next by at least a fold line, the fold lines 213 being along the same linear direction. In this particular example, the blank further comprises a first secondary panel 209 and a second secondary panel 210, such that the first flap 203, the first secondary panel 209, the first main panel 206, the second main panel 207, the second secondary panel 210 and the second flap 205 are successively joined to each other in this order. In this example, the blank further comprises a first tertiary panel 211 and a second tertiary panel 212, such that the first flap 203, the first tertiary panel 211, the first secondary panel 209, the first main panel 206, the second main panel 207, the second secondary panel 210, the second tertiary panel 212 and the second flap 205 are successively joined to each other in this order. Although for illustrative purposes, Figure 5 The blank shown corresponds to the support element 200, but other blanks can correspond to other examples, including panels and fold lines corresponding to respective support elements.

[0050] Figure 6An exemplary planar support element blank 600 according to the present disclosure is shown, in this case similar to support element 300. The blank 600 comprises a first flap 603, a first main panel 606, a second main panel 607 and a second flap 605 which are in this order next to each other, each flap or panel being separated from the next by at least a fold line, the fold lines 613 being along the same linear direction. In this specific example, the blank further comprises a first secondary panel 609 and a second secondary panel 610, such that the first flap 603, the first secondary panel 609, the first main panel 606, the second main panel 607, the second secondary panel 610 and the second flap 605 are in this order next to each other. In this example, the blank further comprises a first tertiary panel 611 and a second tertiary panel 612, such that the first flap 603, the first tertiary panel 611, the first secondary panel 609, the first main panel 606, the second main panel 607, the second secondary panel 610, the second tertiary panel 612 and the second flap 605 are in this order next to each other. In this example, the first main panel 606 and the second main panel 607 have a first maximum width along a direction parallel to the linear ridge, and the first flap 603 has a second maximum width along a direction parallel to the linear ridge, whereby the second maximum width is less than 90% of the first maximum width. This configuration allows for saving material while maintaining the functionality of the support element provided by the cardboard structure. In this example, the first and second flaps have beveled edges which also contribute to saving material.

[0051] In some examples, one or more panels such as a main panel, a secondary panel or a tertiary panel, a first panel or a second panel have a width along a direction parallel to the linear ridge which varies, for example in order to accommodate different shapes of covers, or to save the amount of material used while maintaining the support functionality of the cardboard support element.

[0052] Figure 7 An exemplary planar blank assembly 700 is shown, comprising a support element blank according to the present disclosure, in this case support element blank 500 Figure 5 The support element blank 500 is shown, and a cover blank 701 comprising a first side flap 702, a second side flap 703 and a top panel 704 between the first side flap 702 and the second side flap 703, whereby the first flap 503 is fixed to the first side flap 702, whereby the first main panel 506 and the second main panel 507 are freely resting on the top panel 704, and whereby the second flap 505 is fixed to the second side flap 703. In other examples, the second flap 505 is fixed to the top panel 704. The support element blank can comprise other panels, for example Figure 5 The support element blank 500 is described. The cover blank can further comprise other panels or flaps than the ones shown here.

[0053] Figure 8 An exemplary method of erecting a carton structure and lid according to the present disclosure from a planar blank assembly according to the present disclosure, in this case planar blank assembly 700, is shown, the method comprising folding first side flap panel 702 to form a side flap of the lid, the folding of first side flap panel 702 resulting in the erection of the carton structure away from the top panel in a direction parallel to the direction in which the side flap is folded to form a support element according to the present disclosure. In this example, second side flap panel 703 is also folded to participate in the erection of the lid according to the present disclosure. In this example, first flap 503 is secured to first side flap panel 702 by glue 705. In this example, second flap 505 is secured to second side flap panel 703 by glue 706. In another example, the second flap can be glued to the top panel of the lid, in which case the carton structure can be erected by folding only the first flap.

[0054] The fact that the main panels of the support element blank rest freely on the top panel of the lid blank and the fact that the first and second flaps are secured results in the erection of the carton structure according to the present disclosure, with at least one of the first and second flaps being secured to a side flap panel of the lid. This configuration allows the provision of a flat planar blank assembly according to the present disclosure onto a production line, which flat planar assembly results in the erection of the lid using a reduced number of actions by folding the side flaps of the lid. As a result of the securing of the first and second flaps, with at least one of the first and second flaps being secured to a side flap panel of the lid, and as a result of the first and second main panels resting freely on the top panel and being thereby removed from the top panel by folding actions, the folding of the side flaps of the lid results in the erection of the carton structure of the lid side flaps and support element. While this is shown using a particular blank structure, the same effect can be obtained using other blank structures according to the present disclosure. To allow for the erection, panels located between the first and second flaps, such as secondary panels or third panels, should also rest freely on the top panel so as to slide naturally into place. The support element structure fold lines can be configured to form the support element as desired, for example by folding in one sense or in another sense. In some examples, when first and second secondary panels are provided, the first and second secondary panels each comprise at least one reinforcing element in order to maintain the planar configuration of each of the first and second secondary panels and to assist in the erection of the carton structure. Other examples include secondary panels without such reinforcing elements. Other panels or flaps can include reinforcing elements.

[0055] As Figure 8As shown, the third panel can push the sub-panel resting flush against the top panel, causing the main panel to lift. In this configuration, the first and second flaps are separated from the third panel by a fold line that is a distance 801 from the base plane, which distance forms a triangular space 802, 803 formed by each third panel, a portion of the respective side wing flap of the lid, and a portion of the top panel.

[0056] Figure 9A A planar blank assembly 900 according to the present disclosure is shown. It is important to note that the planar blank assembly according to the present disclosure greatly simplifies transportation in a stack formed by a plurality of such planar blank assemblies stacked on top of each other, whereby for each planar blank assembly of the stack, the blank of the lid is flush with the blank of the cardboard support element, whereby no element "protrudes" from the planar blank assembly, enabling transportation in a stable, efficient and cost-effective manner, reducing the risk of damaging the planar assembly. The planar blank assembly 900 comprises Figure 5The support element blank 500 and the lid blank 901 are shown, the lid blank 901 comprising a first side wing panel 902, a second side wing panel 903 and a top panel 904 between the first side wing panel 902 and the second side wing panel 903, whereby the first wing 503 is secured to the first side wing panel 902 by a glue joint 905, whereby the first main panel 506 and the second main panel 507 are free to rest on the top panel 904, and whereby the second wing 505 is secured to the second side wing panel 903 by a glue joint 906. The lid blank 901 further comprises panels and panels that allow four lid side wings to be formed, whereby the first side wing panel 902 and the second side wing panel 903 form two opposing short lid side wings, and panels 907 and 908 form two opposing long lid side wings. In this example, each long lid side wing corresponding to panels 907 and 908 comprises a reinforced side wing section 909 and 910. In some examples, such reinforced side wing sections comprise a main layer and an additional layer for reinforcement. In some examples, such reinforced side wing sections comprise a folded additional layer. In some examples, such additional layers are glued to the main layer of the side wing. In some examples, either or both of the box and the lid comprise a reinforcement region. Such reinforcement region may, for example, comprise a curved or folded region. Such reinforcement region may, for example, comprise additional glue material or layers. Such reinforcement region can comprise an insert or sleeve. In some examples, the reinforcement region covers a specific region of the box or lid. In some examples, the reinforcement region comprises the box base. In some examples, the reinforcement region comprises the side walls. In some examples, the reinforcement region comprises the side wings of the lid. In some examples, all regions of the box are reinforced. In some examples, all regions of the lid are reinforced. In some examples, the reinforced side wing sections comprise locking tabs. In some examples, the reinforced side wing sections comprise a main side wing section and a folded side wing section placed flush against the main side wing section, the main side wing section being hinged to the folded side wing section at an end of the reinforced side wing section distal from the top of the lid. Such side wing reinforcement can help to reinforce the structure of the closed container. Using side wing reinforcement, in particular folded side wing reinforcement in the flat blank assembly according to the present disclosure, allows for the same or similar thickness of the flat blank assembly at the edges of the flat blank assembly (by the double thickness formed by the side wing reinforcement) and towards the centre of the flat blank assembly (by the support element blank), which same or similar thickness of the flat blank assembly allows for stable stacks of such flat blank assemblies to be obtained for transportation to the production facility.

[0057] Figure 9B An exemplary stack 911 of a plurality of flat blank assemblies according to the present disclosure is shown, whereby each lid blank comprises a folded side wing section. In the example shown, the stack is formed along Figure 9AEach planar blank assembly of the stack 911 can be seen in the direction V indicated by the arrow. The stack 911 comprises 7 planar blank assemblies according to the present disclosure. The stack can comprise more than 10 planar blank assemblies. The stack can comprise more than 20 planar blank assemblies. The stack can comprise more than 50 planar blank assemblies. The stack can comprise more than 70 planar blank assemblies. The stack can comprise more than 100 planar blank assemblies. The stack can comprise more than 150 planar blank assemblies. In this example, each planar blank assembly comprises a back-folded side wing section 910 and a back-folded side wing section 909 for side wing reinforcement, as well as a planar support element blank such as the planar support element blank 500, and a cover panel such as the second side wing flap 903, the planar support element blank and the back-folded side wing sections being placed flush on the second side wing flap. This forms a stable stack structure for transport. In this example, the thickness of the planar support element blank is substantially equal to the thickness of the back-folded side wing sections.

[0058] Figure 10 A cover is shown obtained using a planar blank assembly 900 according to the present disclosure, in this case a planar blank assembly 900 according to the present disclosure. Figure 9A The method of erecting a cover using a planar blank assembly 900 according to the present disclosure. As shown, the method comprises folding the first side wing flap 902 to form a side wing of the cover, the folding of the first side wing flap 902 resulting in an erection of the carton structure away from the top panel 904 in a direction parallel to the direction of folding the side wing, to form a support element according to the present disclosure.

[0059] The cover obtained using the planar blank assembly 900 corresponds to a consumer product 400 according to the present disclosure. Figure 4 The cover 300 is shown. The consumer product 400 comprises a support element that enters the opening in a shape having a triangular cross-section in the plane, thereby reproducing a shape similar to an inverted hipped roof.

[0060] Exemplary support elements according to the present disclosure can be described using vocabulary used in roof types. Exemplary support elements according to the present disclosure can comprise a carton structure forming an open hipped shape comprising a first main panel and a second main panel and a ridge between the first main panel and the second main panel. Exemplary support elements according to the present disclosure can comprise a carton structure forming a complex folded shape comprising a first main panel and a second main panel, a first minor panel and a second minor panel, and a ridge between the first main panel and the second main panel. Exemplary support elements according to the present disclosure can comprise a carton structure forming a salt box shape comprising a first main panel and a second main panel and a ridge between the first main panel and the second main panel.

[0061] In some examples, the linear ridge is a line of symmetry of the carton structure or support element. This is the case for example for support elements formed from blanks 500 or 600. This is particularly adapted to the case of a lid comprising an actuator or actuation area located in the center of the side wing, whereby such a lid can be placed in one sense or in the other sense while remaining functional due to its symmetrical structure. In other words, see for example Figure 4 When the actuation area 404 is aligned to correspond to the actuator 403, the lid 300 is reversible and by placing the lid in a symmetrical manner, it is possible to make the actuation area 405 correspond to the actuator 403.

[0062] A support element according to the disclosure can comprise a support element distal end located at a depth when the lid is in the closed position. In some examples, the depth is at least 3 mm and less than 50 mm from the top of the lid. 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 support element participates in reinforcing the structure of the consumer good. The combination of the depth and shape of the support element and the amount of gap distance can allow avoiding twisting the lid.

[0063] In some cases, a force is applied to the side wing in a direction normal to the base of the box, in a direction from the base of the box towards the top of the lid. Such a force can be applied for example when the box is lifted from the floor to transport the box. In this case, the gap distance separating the side wall from the support element can be reduced to zero due to the weight of the content and of the box being applied to the locking tab through the actuator. In this case, the support element allows avoiding accidental opening of the box due to the side wall sagging to the extent that the actuator would be released from the locking tab, the box falling on the floor, the lid remaining in the hand of the person who lifted the box by holding the box with the lid. In this example and some other examples, the weight of the detergent product exceeds 50% of the weight of the consumer good, whereby the gravitational force generated by the detergent product on the base of the box in the absence of a counterforce on the base of the box causes the flexion of a particular portion of the side wall and reduces the gap to zero, the actuator remaining abutted against the locking tab when the gap is reduced to zero and when no actuation pressure is applied. In some examples, in this case, the weight of the detergent product exceeds 70% of the weight of the consumer good. In some examples, in this case, the weight of the detergent product exceeds 80% of the weight of the consumer good.

[0064] In some cases, a force is applied to the actuator in a direction normal to the side wall, in a direction towards the interior of the box, for example by gripping the lid with one hand (thumb on one side and other fingers on the other side). Such a force can be applied for example when lifting the box from the floor to transport the box. In this case, the gap distance can be reduced to zero as the force clamps the side wall between the support element and the actuator. In this case, the static friction force between the side wall and the support element allows to avoid accidental opening of the box due to the lid being disconnected from the side wall, the box falling on the floor, the lid remaining in the hand of the person who lifted the box by holding the box with the lid.

[0065] In one example, the container is made of cardboard material, and thus of a recyclable material.

In some examples, the unit dose article includes at least three compartments, two of the compartments can be smaller than the third compartment, and in some examples, the smaller compartments are stacked on the larger compartment. In some examples, the stacked compartments are in a side-by-side orientation. In some examples, each individual unit dose article can have a weight of between 10 g and 40 g, or even between 15 g and 35 g. The water-soluble film is capable of dissolving or dispersing in water. Prior to formation into a unit dose article, the water-soluble film has a thickness of 20 microns to 150 microns in some examples, 35 microns to 125 microns in other examples, 50 microns to 110 microns in further examples, and about 76 microns in yet other examples.
