This invention generally relates to containers comprising a box, a lid for the box, and a lock to maintain the lid in a closed position. In order for the lock to be operative, the lid may have to be placed in a specific position. Lid misplacement onto the box may prevent locking, or render locking permanent, preventing unlocking.
A lid is an important structural element of a container as it participates in protecting a content of the container from external conditions, and permits controlling the access to such content. This disclosure focuses on a reversible lid. A reversible lid should be understood as a lid which may be placed on a box to close the box in at least two different orientations. Such a lid may for example take a generally rectangular of oval shape, in which case such lid may be placed on a box in at least two different orientations, whereby such two different orientations correspond to a rotation of the lid by 180 degrees in relation to a central axis of the top of the lid. In some examples, such a reversible lid may be placed on a box to close the box in no more than two different orientations.
In cases of a reversible lid comprising a lock, the lock may have a non-symmetrical structure, for example in order to be adapted to the asymmetrical configuration of an adult human hand, such that the lock may function as expected in one orientation but may be dysfunctional in another orientation of the reversible lid. The present case aims at resolving such a situation.
In this disclosure, the container comprises a box. A box should be understood as a generally parallelepiped, barrel shaped, cylindrical, oval or cubical three dimensional object defining a cavity. The use of parallelepiped boxes may facilitate storage and transportation by permitting piling up boxes in a space efficient manner. In some examples, a box may be a parallelepiped provided with some rounded, tapered trapezium or chamfered edges. The box according to this disclosure comprises a base, a sidewall structure and an opening opposite the base. A base according to this disclosure should be understood as a surface on which the box may lie when placed on a supporting 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. In some examples, the base has an embossed profile standing in or out in relief. The sidewall structure according to this disclosure should be understood as extending from the base, and connecting the base to the opening, or to a transition piece between the sidewall structure and the opening. It should be understood that the connection of the base to the opening may include one or more transition pieces in addition to a sidewall. In some examples, such a transition piece may be glued or otherwise attached to the sidewall structure. In some examples, the sidewall structure is perpendicular to the base. In some examples, the base is rectangular and has four sides, four sidewalls forming the sidewall structure extending perpendicular from the base, each sidewall being rectangular, each side wall being connected by a sidewall side to a side of the base, and by two other sidewall sides to two others of the four sidewalls. In some examples the base is oval and the sidewall structure forms a generally cylindrical barrel shaped wall extending from the base in a direction normal or perpendicular to the base. In some examples, sidewalls have a shape corresponding to one of a square, a rectangle, a trapeze, a polygon, a section of a sphere, a section of an ovoid, or a section of an ellipsoid. The opening according to this disclosure should be understood as a complete or partial aperture providing access to a content of the box. In some examples, the opening faces the base. In some examples, the opening has a surface of less than the surface of the base. In some examples, the opening has a surface larger than the surface of the base in order to provide improved access, for example using sidewalls extending from the base at angle of more than 90 degrees from the base. In some examples, the opening is provided after removal of a tamper proof feature, for example comprising a perforated piece to be removed at first use or a tamper evident sticker locking a lid to the box. In some examples a tamper evident sticker is glued on the lid and on the box, whereby the tamper evident sticker should be broken, teared or perforated at first opening to indicate to a consumer that the container has not been tempered with before purchase. This temper evident sticker may for example be in paper or in plastic. In some examples, the opening is placed on a top panel of the box, the top panel of the box facing, i.e. opposite, the base of the box, the top panel of the box being separated from the base of the box by at least the sidewall structure, the top panel of the box being generally coplanar with the base of the box. 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. In some examples, the opening is a permanent opening. In some examples, the opening is a reclosable opening. Examples of a reclosable opening comprise openings reclosable by a single flap, or a reclosable opening reclosable through a spout like structure, for example a spout like structure comprising a main flap which, in a reclosed position, would cover the opening, and side elements which, when the opening is open, link the main flap with sides of the opening.
The container comprises a lid for the box. The lid according to this disclosure should be understood as an element permitting to repeatedly close or open the opening of the box. The lid may be disconnected and separated from the box, for example to provide an improved access to the content of the box. The lid according to this disclosure comprises a top and flanks. It should be understood that the lid is aimed at covering 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 hexagonal, octagonal, polygonal or oval, structures such as oval being for example approximated by multiplying a number of flanks. 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 while being named “top”, the top of the lid may be positioned in different orientations. The lid comprises flanks. It should be understood that the flanks according to this disclosure are elements connected to the top of the lid and extending from the top of the lid in order to engage the sidewall structure of the box, each flank having an extension along a corresponding sidewall or sidewall structure section. The flanks participate in placing the top of the lid onto the opening. In some examples, the flanks extend perpendicularly from the top of the lid. In some examples, the flanks surround an entire perimeter of the top of the lid. In some examples, the flanks partially surround an entire perimeter of the top of the lid, a portion of the top of the lid being flankless. At least a portion of the flanks covers at least a portion of the sidewall structure of the box when the lid is in the closed position. The box and lid cooperate to participate in fulfilling the role of the container to store, transport and facilitate access to the content of the container.
Due to the lid being in this disclosure a reversible lid, the top is substantially 180 degrees symmetrical around a central axis normal to the top of the lid. In some examples, the central axis is parallel to the flanks. In some examples, the top is rectangular, the central axis passing through the center of the rectangle. In some examples, the top is oval, the central axis passing through the center of the oval. Substantially should be understood as within 10%, preferably within 5%, of a measure concerned, taking into account manufacturing tolerances for example. A non-substantial angular variation would thereby be a variation of less than 18 degrees (5% of 180 degrees), preferably of less than 9 degrees.
The container according to this disclosure comprises a lock. The lock is to repeatedly maintain the lid in a closed or open position. A lock should be in this disclosure understood as a mechanism providing appropriate closure and protection of a content of the box, as well as preventing or reducing the likelihood of an accidental opening. The lock according to this disclosure is to maintain the lid in a closed position. It should be understood that the lock according to this disclosure is expected to function under normal use of the container. It should be understood that the lock may not fulfill its function when for example unusual use is made of the container, or when the container is under unusual conditions.
The lock comprises a specific active actuator moveable from a locking position to an opening position by applying an actuation pressure onto the specific active actuator when the lid is in the closed position. An example specific active actuator is a mechanical structure submitted to a movement upon actuation by an outside force or actuation pressure, such movement leading to the opening of the lock when such movement takes place. In some examples, the specific active actuator is resilient and has a default position, such default position corresponding to the lid remaining closed, a resilience being vanquished by an outside force or actuation pressure in order to open the lid. In some examples, the specific active actuator is resilient in that the specific active actuator comprises a flexible element, such as a flap for example, the flexible element having a default position corresponding to the lid remaining closed, the flexible element being pressed to open the lid, the flexible element springing back to the default position when releasing pressure. It should be understood that a pressure is generated by the application of a force onto a surface. Example specific active actuators have at least two positions being the opening position and the locking position, whereby the opening position corresponds to a position permitting opening of the lid, the locking position preventing opening of the lid to protect the content from humidity or extreme temperature, for example, or reducing the possibility of an accidental opening of the lid.
The specific active actuator is connected to the specific portion of the sidewall structure covered by at least a portion of the flanks of the lid when the lid is in the closed position, the specific active actuator abutting against a corresponding locking tab of the lid when in the locking position, the specific active actuator being for example maintained away from the locking tab when in the opening position, the specific active actuator being displaceable by the actuation pressure by an unlocking displacement distance in a direction normal (i.e. perpendicular) to the specific portion of the sidewall structure. The connection to the specific portion may for example be a fold line at an end of a sidewall away (or distal) from the base. The connection of the actuator to the specific portion of the sidewall structure is due to the actuator participating in locking or unlocking the specific portion of the sidewall structure from the portion of the lid covering the specific portion of the sidewall structure, thereby permitting selectively releasing the lid from the box. The lid comprises a locking tab. A locking tab should be understood as a mechanical element which interlocks with the active actuator. In some examples the locking tab extends away from part of the lid and may be in the form of a bulge, a ridge, an embossment or an additional material layer sticking out of the lid and towards the specific portion of the sidewall structure such that the active actuator may abut against the tab when in the locking position to prevent separating the specific portion of the sidewall structure from the lid in the area of the active actuator. In some examples, the locking tab is comprised in the lid itself, the locking tab being for example formed by an aperture in a flank of the lid. Abutment according to this disclosure should be understood as a contact between the active actuator or part of the active actuator and the corresponding locking tab, such contact preventing opening of the lid. In some examples the active actuator is maintained away from the locking tab by pressure when in the opening position, in order to release the locking tab. Such release of the locking tab permits opening the lid. Displacement or movement of the active actuator from the locking to the opening position is by application on the active actuator of the actuation pressure or force such that the actuator is displaced by a distance sufficient to supress contact of the actuator with the locking tab, such distance corresponding to the displacement distance, in a direction normal to the specific portion of the sidewall structure. Such force or pressure may also comprise a minor component which may be parallel to the sidewall structure, due to the fact that the force or pressure may be applied by a finger of a human adult hand which does not necessarily align force completely perfectly. The actuation is however triggered by a component of such force or pressure being normal to the portion of the sidewall structure. Such presence requirement of a component normal to the portion of the sidewall structure in order to unlock the lock participates in the role of the lock avoiding an accidental opening, for example in absence of such normal force component, whereas desired opening would take place by a consumer “pushing” the active actuator and applying the unlocking force or pressure permitting opening of the lid.
In order to provide precision in locating a finger appropriately, the flanks comprise a specific actuation area, the actuation area facing the specific active actuator. The fact that such actuation area faces the actuator indeed permits locating either the thumb or one or more of the other fingers on exactly the area on which a lock opening force should be applied. The specific actuation area should be understood as defining a localised discontinuity on the flanks, whereby a user or consumer may perceive such discontinuity in order to correctly locate the thumb or one or more other fingers. Such discontinuity may comprise one or more of an actuation aperture, an actuation flap, an actuation slit, an actuation membrane, or tactile elements comprised in or applied to a surface of the flank such as embossments, debossments, surface texturing, buttons or the like. In some examples, the actuation area or the specific portion comprises a visual indication indicating the location of the actuation area. In some examples whereby the actuation area is an aperture, the specific portion may comprise a visual indication visible through the aperture, respectively apertures, when the lid is closed. 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 colour or a specific text providing instructions such as “push here to open” for example, or a combination of any of these indications. The specific actuation area is configured to permit displacing the specific active actuator from the locking position to the opening position by applying the actuation pressure at the specific actuation area when the lid is in the closed position. In order to appropriately place the thumb or one or more other fingers, the actuation area can in some examples span less than 8 cm2 and more than 0.2 cm2 in order to reduce or avoid lack of precision in finger placement, and, on the other hand, avoid that the specific actuation area be so small that it would result difficult to locate for a user or consumer. In some examples, the actuation area has a circular shape in order to ease positioning. Other shapes may be considered such as, for example, elliptical, oval, square, triangular, square with rounded corners, triangular with rounded corners, other polygonal shapes or other polygonal shapes with rounded corners.
In some examples, an actuation area spans less than 8 cm2 and more than 0.2 cm2, each actuation area defining a centroid; each centroid being separated from the top of the lid by less than 5 cm and by more than 0.5 cm; each centroid being separated from a distal end of the corresponding flank by more than 0.5 cm; and the top of the lid spans less than 13 cm and more than 6 cm along a direction normal to the specific portion at the centroid, in particular at the centroid of a second actuation area when present. Complying with such combined conditions was found particularly suited to reaching all the actuation areas with a single adult hand at the same time.
The box comprises a specific passive actuator connected to a second portion of the sidewall structure. A passive actuator should be understood as having characteristics equal to or similar to an active actuator, except that the passive actuator does not participate in locking the box, while an active actuator does participate in such locking. In fact, the specific passive actuator is connected to a second portion of the sidewall structure so that it may serve as an active actuator if the reversible lid would be placed in an alternative, reversed, position. The specific passive actuator and the specific active actuator are indeed paired to be substantially symmetrically located at 180 degrees from each other around the central axis when the lid is in the closed position. In other words, considering a reversible lid having a first placement position and a second placement position different from the first position, both positions permitting repeatable closing and opening of the box, a given actuator is an active actuator in the first lid position and the same given actuator is a passive actuator in the second lid position. An actuator in fact becomes a passive actuator according to this disclosure due to the specific passive actuator being inactivated by a specific inactivation configuration of the lid when the lid is in a closed position, the specific inactivation configuration and the locking tab corresponding to the specific active actuator being substantially symmetrically located at 180 degrees from each other around the central axis.
Example container 100 comprises a box 101, a reversible lid 102 for the box, and a lock 103 to maintain the lid in a closed position, the box comprising a base 104, a sidewall structure 105 and an opening 106 opposite to the base, the lid comprising a top 107 and flanks 108, the top covering the opening, whereby the top is substantially 180 degrees symmetrical around a central axis CA normal to the top, whereby at least a portion of the flanks covers at least a specific portion 150 of the sidewall structure of the box when the lid is in the closed position, the lock comprising a specific active actuator 130 moveable from a locking position to an opening position by applying an actuation pressure AP onto the specific active actuator when the lid is in the closed position, whereby the specific active actuator 130 is connected to the specific portion 150 of the sidewall structure, whereby the specific active actuator abuts against a corresponding locking tab 140 of the lid when in the locking position, the specific active actuator being displaceable by the actuation pressure by an unlocking displacement distance in a direction normal to the specific portion of the sidewall structure, whereby the flanks comprise a specific actuation area 180, the actuation area facing the specific active actuator, the specific actuation area being configured to permit displacing the specific active actuator from the locking position to the opening position by applying the actuation pressure AP at the specific actuation area 180 when the lid is in the closed position, the box comprising a specific passive actuator 131 connected to a second portion 151 of the sidewall structure, the specific passive actuator 131 and the specific active actuator 130 being paired to be substantially symmetrically located at 180 degrees from each other around the central axis CA when the lid is in the closed position, whereby the specific passive actuator is inactivated by a specific inactivation configuration of the lid when the lid is in the closed position, the specific inactivation configuration and the locking tab (corresponding to the specific active actuator) being substantially symmetrically located at 180 degrees from each other around the central axis. One should note that plane P intersects the passive and active actuators for illustration purposes, the central axis being comprised in plane P.
As illustrated in
Such a configuration permits placing the lid either as illustrated, or in a reversed position (not illustrated here) whereby the actuator 131 would face locking tab 140 and become the active actuator, whereas the actuator 130 would, in turn, face the inactivation configuration and become the passive actuator. The lock would thereby be functional regardless of the orientation of the reversible lid, in this case with a single lock feature 103.
Example container 200 comprises a box 201, a reversible lid 202 for the box, and a lock 203 to maintain the lid in a closed position, the box comprising a base 204, a sidewall structure 205 and an opening 206 opposite to the base, the lid comprising a top 207 and flanks 208, the top covering the opening, whereby the top is substantially 180 degrees symmetrical around a central axis CA normal to the top, whereby at least a portion of the flanks covers at least a specific portion 250 of the sidewall structure of the box when the lid is in the closed position, the lock comprising a specific active actuator 230 moveable from a locking position to an opening position by applying an actuation pressure onto the specific active actuator when the lid is in the closed position, whereby the specific active actuator 230 is connected to the specific portion 250 of the sidewall structure, whereby the specific active actuator abuts against a corresponding locking tab 240 of the lid when in the locking position, the locking tab being represented in dashed line due to being placed inside of the corresponding lid flank in this illustrated configuration, the locking tab 240 being for example produced by folding back of a lid flank panel (see for example the lid blanks described in
As illustrated in
Such a configuration permits placing the lid either as illustrated, or in a reversed position (not illustrated here) whereby the actuator 231 would face locking tab 240 and become the active actuator, whereas the actuator 230 would, in turn, face the inactivation configuration and become the passive actuator. The lock would thereby be functional regardless of the orientation of the reversible lid, in this case with a single lock feature 203.
Example container 300 comprises a single additional pair of active actuators, whereby a specific flank 308 comprises one of the respective additional actuation areas, such respective additional actuation area 383 being a single actuation area of the specific flank 308. Such a configuration may be particularly suited to operating the lock using a single adult hand, the single actuation area 383 being operated by a thumb of the single adult hand and the other actuation areas 382 and 280 being simultaneously operated by two other fingers of the same adult hand to unlock the container. In some examples, in order to centre a lock comprising such single additional pair of active actuators, the single actuation area of the specific flank is located off-center of the specific flank as represented in
As illustrated in a number of examples, each actuator comprises a dedicated flap. In some other examples, some actuators may share a same flap, in particular actuators located on a same side wall. When sharing a same flap, flap flexibility may require applying pressure simultaneously at the different actuators corresponding to the shared flap in order to unlock such actuators.
In some examples, the container comprises a plurality of adjacent actuation areas having respective centroids separated by more than 1 cm and by less than 12 cm along a direction parallel to the top of the lid and tangential to the sidewall structure, in order to permit operating the corresponding active actuators with fingers of a same adult hand other than the thumb. In some examples, the container comprises a plurality of adjacent actuation areas having respective centroids separated by more than 1.5 cm and by less than 9 cm along a direction parallel to the top of the lid and tangential to the sidewall structure. In some examples, the container comprises a plurality of adjacent actuation areas having respective centroids separated by more than 1.5 cm and by less than 5 cm along a direction parallel to the top of the lid and tangential to the sidewall structure.

In some examples the liquid laundry detergent composition comprises less than 15%, or less than 12% by weight of the liquid laundry detergent composition of water. In some examples, the laundry detergent composition is a liquid laundry detergent composition comprising a non-aqueous solvent selected from 1,2-propanediol, dipropylene glycol, tripropyleneglycol, glycerol, sorbitol, polyethylene glycol or a mixture thereof. In some examples, the liquid laundry detergent composition comprises between 10% and 40%, or between 15% and 30% by weight of the liquid laundry detergent composition of the non-aqueous solvent. In some examples, the laundry detergent composition comprises a perfume. In some examples, the laundry detergent composition comprises an adjunct ingredient selected from the group comprising builders including enzymes, citrate, bleach, bleach catalyst, dye, hueing dye, brightener, cleaning polymers including alkoxylated polyamines and polyethyleneimines, soil release polymer, surfactant, solvent, dye transfer inhibitors, chelant, encapsulated perfume, polycarboxylates, structurant, pH trimming agents, and mixtures thereof. In some examples, the laundry detergent composition has a pH between 6 and 10, between 6.5 and 8.9, or between 7 and 8, wherein the pH of the laundry detergent composition is measured as a 10% product concentration in demineralized water at 20° C. When liquid, the laundry detergent composition may be Newtonian or non-Newtonian. In some examples, the liquid laundry detergent composition is non-Newtonian. Without wishing to be bound by theory, a non-Newtonian liquid has properties that differ from those of a Newtonian liquid, more specifically, the viscosity of non-Newtonian liquids is dependent on shear rate, while a Newtonian liquid has a constant viscosity independent of the applied shear rate. The decreased viscosity upon shear application for non-Newtonian liquids is thought to further facilitate liquid detergent dissolution. The liquid laundry detergent composition described herein can have any suitable viscosity depending on factors such as formulated ingredients and purpose of the composition.
The container is preferably a cardboard or paperboard container.
Paperboard or cardboard is, mechanically speaking, a relatively flexible material, meaning that a wall of a container made of paperboard or cardboard may offer little resistance to getting bent under an external pressure. In some applications where resistance to getting bent and/or high tear resistance is of importance, a material different from paperboard or cardboard may be used. Materials different from paperboard or cardboard may however not be as straightforward to recycle. Such choice of material thereby results of a compromise. An objective of the present disclosure is to propose a container comprising a lid, whereby the inclusion of a reinforced lid corner leads to reinforcement of the whole container structure, permitting use of paperboard or cardboard in applications which would otherwise be compromised by using another material.
As the container according to this description may be shaped using folding machinery which is likely to be already in place at a manufacturing location, little or no additional capital is required at a manufacturing location to implement the structures according to this disclosure.
A lid, box or container according to this disclosure may be made from paper material wherein the paper material is for example selected from paperboard, cardboard, laminates comprising at least one paper board or cardboard layer. Paperboard or cardboard comprise cellulose fibre materials or a mixture thereof. The material used to make the lid, box or container may comprise other ingredients, such as colorants, protective varnishes, surface enhancement coatings, barrier coatings, preservatives, recycled fibre materials, plasticisers, UV stabilizers, oxygen barriers, perfume barriers, and moisture barriers, or a mixture thereof. In some examples, in order to provide a desired tear resistance and strength, cellulose fibres lengths is in a range from 0.1 to 5 mm, preferably from 1 to 3 mm. In some examples, cellulose fibres are sourced from various sources such as virgin soft or hard woods, hemp, grass, corn, bagasse, sugarcane, bamboo and others, and/or from post producer or post-consumer recycled paper and cardboard.
The lid, box or container may comprise areas of external or internal printing. The lid, box or container may be made for example by cardboard making. Suitable lid, box or container manufacturing processes may include, but are not limited to, tube forming from a flat cardboard or paperboard sheet with a gluing step, folding, or a mixture thereof. The lid, box or container may be opaque or filter some specific wavelengths, for example to protect content from external light. In some examples the lid, box or container is constructed at least in part and in some specific examples in its entirety from paper-based material. By paper-based material, we herein mean a material comprising paper. Without wishing to be bound by theory, by ‘paper’ we herein mean a material made from a cellulose-based pulp. Paperboard may be made from a paper-based material having a thickness and rigidity such that it does not collapse under its own weight. While paperboard should be understood as comprising a single layer of material, cardboard should be understood as comprising a plurality of paper-based material layers. In some examples, the paper-based material comprises paperboard, cardboard, or a mixture thereof, wherein preferably, cardboard comprises paperboard, corrugated fiber-board, or a mixture thereof. Corrugated fiber-board comprises a series of flutes. Each flute can be understood to be a channel. The flutes run parallel to one another, with the flute direction being the direction travelled along each channel. The paper-based material may be a laminate comprising paper, cardboard, or a mixture thereof, wherein in some examples, cardboard comprises paperboard, corrugated fiber-board, or a mixture thereof, and in some examples at least another material. In some examples, the at least another material comprises a plastic material. In some examples, the plastic material comprises polyethylene, more specifically Low Density PolyEthylene (LDPE), polyethylene terephthalate, polypropylene, polyvinylalcohol or a mixture thereof. In some examples the plastic material comprises a copolymer from an ethylene starting monomer and vinyl alcohol, or EVOH. A barrier material may be used as the at least another material. The barrier material may be a biaxially orientated polypropylene, a metallised polyethylene terephthalate, or a mixture thereof. The at least another material may comprise a wax, a cellulose material, polyvinylalcohol, silica dioxide, casein based materials, or a mixture thereof. In some examples, the paper-based laminate comprises greater than 50%, preferably greater than 85%, and more preferably greater than 95% by weight of the paper based laminate of fiber-based materials. In some examples, the barrier material may comprise plastic material having a thickness of between 10 micron and 60 micron. In some examples, the barrier material may comprise plastic material having a thickness of between 10 micron and 35 micron. The paper-based material may be a laminate. In some examples, the internal surface of a lid, box or container comprises paperboard, cardboard, or a mixture thereof, wherein, in specific examples, cardboard comprises paperboard, corrugated fiber-board and lamination of polyethylene, especially LDPE, or a mixture thereof, and, in some examples, the external surface of the lid, box or container or a combination thereof comprises the at least another material. Alternatively, the at least another material might also be laminated in-between two paper-based material layers such as the paperboard or cardboard layers as per this disclosure. Without wishing to be bound by theory this at least another material might act as a barrier for leaked liquid absorbed by the paper-based material facing the interior side of the lid, box or container, to prevent or reduce a contaminating flow through a wall of the lid, box or container. Other structures may be found efficient to avoid leakage from the content or to protect the content from external fluids, for example from a shower, a sink, or by handling the container or the lid with wet hands. Contamination of a wall of the lid, box or container might be unsightly to consumers or may contaminate the storage area. In some examples, the lid, box or container are made of a paper-based material comprising the at least another material laminated in between two corrugated fiberboard layers. In some examples, the material used for the lid, box or container comprises a core cardboard flute material sandwiched between two plain cardboard (or paperboard) layers and polyethylene laminate. A paperboard or cardboard layer according to this disclosure may be made from or comprise recycled material or recycled cellulose fibres. The external surface of the lid, box or container may comprise a coating or a varnish. Such a coating or varnish can help making a board repellent to water or help protecting a content such as an enclosed detergent composition from UV light. The coating or varnish could also help protecting the external surface of the lid, box or container from being contaminated by the content, for example an enclosed detergent composition, for example if leakage of a water-soluble unit dose detergent enclosing a liquid detergent composition would occur.
A coating or vanish on the internal surface can help to prevent the content to stick to the inner surface or prevent migration of inks, colorants, perfumes, non-ionics, oils, greases and other ingredients from the content into the board or inks or additives from the board onto the content. In some examples detergent resistant varnishes or coatings can be applied on areas exposed to the contents.
In some example methods, whereby the example container comprises a single additional pair of active actuators, whereby a specific flank comprises one of the respective additional actuation areas, such respective additional actuation area being a single actuation area of the specific flank, whereby the lid of the example container comprises a flank opposite to the specific flank, such opposite flank comprising the specific actuation area and an additional actuation area paired with the single actuation area of the specific flank, as illustrated for example in
Example combinations of a box blank and of a lid blank may indeed be provided, whereby the box blank is configured to be folded into the box of any of the above container examples, and whereby the lid blank is configured to be folded into the lid of any of the respective container examples.
An example box blank, such as example blank 1210, comprises one or more flap pairs corresponding to actuator pairs, whereby each flap pair comprises a first flap 230 in a first sidewall panel and a second flap 231 in a second sidewall panel of the box blank. Example blank 1210 is illustrated with the flaps being numbered corresponding to a possible box configuration, taking into account that such box configuration and distribution of active and passive actuators would depend on the lid orientation.
An example lid blank, such as either lid blank 1220 or lid blank 1230, comprises at least one inactivation configuration 441 and one or more locking tabs 240 (which in this example provides a double locking tab as illustrated in
In some examples, the lid blank is made from a multilayer material comprising the following layers, in this order: GD2 210 (95%), HPF 140 (85%), and BK 170 (0%), the GD 210 layer facing the outside of the container when the container is closed.
In some examples, the transversal support element is made from a single layer of GK 600 (0%).
In some examples, the box blank is made from a multilayer material comprising the following layers, in this order: GD2 210 (95%), HPF 140 (85%), W112 (95%), PE 15 (0%) and W112 (95%), the GD 210 layer facing the outside of the container when the container is closed. In the three paragraphs directly above, GD2 should be understood as Gestrichenen Duplex (a German classification codes for boards) corresponding to recycled board with a clay top coating for printing. HPF should be understood as High performance F-flute, a particularly resistant version of F-flute which forms in some examples a middle corrugated layer. BK should be understood as Bleached Kraft board, a robust and tear resistant virgin fibre board which is bleached for appearance and printing. W should be understood as a white liner. PE stands for polyethylene. The numbers 210, 140, 170 and 112 following the letter codes of the materials are weight in grams per square meter of material. Between brackets is the amount of recycled content.
The container may be made from rigid paperboard or cardboard material, flexible paperboard or cardboard material or a mixture thereof. In some examples, the layer material forming the box or the lid has a wall thickness of more than 300 microns and of less than 6 mm per layer. In some examples, the layer material forming the box or the lid has a wall thickness of more than 1 mm and of less than 2 mm per layer. The container may be made from paper materials, bio-based material, bamboo fibres, cellulose fibres, cellulose based or fibre-based materials, or a mixture thereof. The container may be made from materials comprising recycled materials, for example recycled cellulose fiber-based materials. In some examples, the container is made from C (3.2 mm) flute corrugated cardboard. In some examples, the container is made from double wall cardboard, in some examples made from double wall cardboard up to 5 mm thick per double wall layer.
In some examples the flanks of the lid cover about 30% of the sidewall structure of the box, 30% corresponding in this case to a ratio between on 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 the height of the sidewalls in the direction normal to both the top of the lid and the base of the box. In an example, the flanks completely surround the sidewalls around the opening. Such coverage of the flanks participates in ensuring lid placement, structural resiliency and protection of the content. In some examples, the flanks cover at least 50% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover at least 75% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover at least 90% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover 100% of the sidewalls when the lid is in the closed position. Increasing flank coverage increases robustness. In some examples, the flanks cover at most 90% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover at most 80% of the sidewalls when the lid is in the closed position. In some examples, the flanks cover at most 70% of the sidewalls when the lid is in the closed position. Decreasing flank coverage can ease opening of the container by providing grip surface on both the lid and the box sidewalls. In some examples, a manufacturing process comprises providing different box sizes, for example boxes having a sidewall height of either 10 cm, 11.5 cm, 13.5 cm or 16 cm, whereby each box may be provided with a same lid fitting all box sizes provided, such as a lid having a flank height of 7 cm. In some examples, flank height is of more than 3 cm. In some examples, flank height is of more than 5 cm. In some examples, flank height is of more than 6 cm. In some examples, flank height is of 9 cm or more. In some examples, flank height is of 12 cm or more. In some examples, sidewalls of the box have a sidewall height along a direction perpendicular to the base of 30 cm or more. In some examples, sidewalls of the box have a sidewall height along a direction perpendicular to the base of up to 40 cm.
In some examples, reinforced lid corners may be provided by folding a double layer, in which reinforced corners may comprise cut-out features such as described in pending patent application EP22214415.6 integrated hereby by reference.
