Description

Background Art

[0001] The present invention as a whole relates to container blanks for making containers. In a non-limiting example, the container blank is intended to be folded to form a container that can be filled with a detergent product. Such containers containing detergent products constitute consumer products present in consumer households, especially in rooms such as kitchens, laundry rooms or bathrooms. These locations often constitute humid environments. Importantly, the container is configured so that it fully protects the detergent product from being degraded due to excessive exposure to excessively high temperatures or such moisture or humidity.

[0015] Document DE 92 00 577 U1 shows a container blank for accommodating medical and sanitary products. This container blank is not designed to accommodate detergent products: detergent products are sensitive to humidity and temperature. They should be accommodated in specially designed containers, and in particular can be properly sealed, for example, to form a container that prevents spillage. When the container is filled, transported, stored or in use, they can be manipulated, and the container should ensure that no contents leave the container. The specific offset between the fold lines of the container blank of the present disclosure provides a substantial benefit that is superior to the known container blank in terms of reduced spillage and reduced moisture intrusion.

[0016] In addition, for environmental reasons, the amount of material to be used to manufacture the container should be as small as possible, while reliably shielding the detergent product from moisture. Also for environmental reasons, it is advantageous that the container does not contain small additional elements such as clamps, staples, tear strips that separate from the container during use and make the recycling process cumbersome.

[0017] In other words, the container blanks of the present disclosure use a reduced amount of material while enabling a container that avoids or inhibits undesirable loss of contents without compromising protection against extreme temperatures or moisture intrusion.

[0018] The present disclosure focuses on container blanks. Container blanks should be understood as intermediate products intended to eventually form containers. Container blanks (or die-cut pieces) are substantially flat objects that are specifically designed to be fed to machines that can perform various operations such as folding, gluing, etc. to obtain containers. The blank can be made of a whole piece, or can include several pieces attached together. The container blank can be made of one of the materials or layered materials discussed further below. The blank has a thickness that is substantially less than its overall width or length. The thickness throughout the blank can be uniform, or the thickness can vary.

[0019] The blank may be composed of one or more panels and one or more flaps separated from each other by crease lines. Crease lines should be understood as linear segments of the blank that have been subjected to a crease process in order to provide well-defined folding lines. They facilitate the folding operation and enable a container with an intended shape and function to be obtained. When referring to the blank in the present disclosure, and unless otherwise explicitly mentioned, the panel is generally intended to depict a portion of the blank bounded by at least two crease lines. Unless otherwise explicitly mentioned, the flap is generally intended to depict a portion of the blank bounded by a single crease line and just connected to one panel. When referring to the container being obtainable by a container blank, the flap is a portion of the container that is hinged to another portion of the container at the fold line. The relative movement of the flap relative to the other portion may be partially or completely prevented by other flaps or by attaching the flap to other portions of the container. In some examples, the container is made of a corrugated material comprising a groove extending in the longitudinal direction. The crease line separating the flap from the panel may extend perpendicular to the orientation of the groove. This may provide a memory effect to facilitate (unfolding) the folding flap. The crease line separating one panel from another panel may extend along the orientation of the groove.

[0020] It should be understood that the blank may include one or more main panels and one or more secondary panels, in some examples, one or more main panels having a larger size than one or more secondary panels. In some examples, the main panels and secondary panels are intended to form the side walls of the resulting container.

[0021] In one example, the blank comprises a primary flap and a secondary flap. A primary flap should be understood as a flap connected to a primary panel, and a secondary flap should be understood as a flap connected to a secondary panel. A primary flap does not necessarily have a larger size than a secondary flap.

[0022] In some examples, the blank is provided with a secondary panel, the secondary panel supporting at least one secondary flap.The secondary panel may have a secondary function, such as attaching the primary panel and the secondary panel together.

[0023] In some examples, the panels and fins may have a generally rectangular shape. In some examples, at least some of the panels or fins may have a generally square, polygonal, circular, or elliptical shape. In some examples, at least one of the panels or at least one of the fins has a different width than the other panels and fins.

[0024] In the present disclosure, the longitudinal direction is defined as extending parallel to the longest dimension (= length) of the main panel, and the transverse direction is defined as extending parallel to the second longest dimension (= width) of the main panel. In one example, the longitudinal direction of the blank may correspond to the vertical direction of the resulting container when such a container is placed on its base for use.

[0025] In this example, the panel is directly connected to the flap or another panel to mean that the panel is adjacent to the flap or another panel and the panel is separated from the flap or another panel only by a fold line. In other words, there is no additional element of the container blank inserted between the panel and the flap or other panel.

[0026] In the present disclosure, a free edge portion is intended to describe the edge of the container blank delimiting the material.A longitudinal free edge portion is a free edge portion extending substantially parallel to the longitudinal direction.

[0027] The crease lines of the first main wing and the first secondary wing can be offset longitudinally relative to each other. Such crease lines are arranged parallel to the transverse direction and are not colinear, and therefore the distance between the two lines can be defined. The distance constitutes an offset between the two lines arranged at different positions. For the resulting container, the offset causes the folding lines of the container to be not located at the same height. The offset is selected to correspond to a value related to the thickness of the wing, that is, between 100% and 200% of the thickness of the secondary wing. When the blank wing and the blank panel are folded and fitted together, the offset enables a spill-proof and robust container to be obtained. In some examples, the offset enables the wing to be folded at a 90 ° angle so that the continuous wing layer forms a multi-layer spill-proof covering.

[0028] All or only some of the transverse crease lines may be offset. For example, the offset may be single offset or double offset, depending on the number of flaps to be folded (in the resulting container) between two adjacent crease lines. A single offset may separate the crease lines by a distance between 50% and 100% of the thickness of the flap, while a double offset may separate the crease lines by a distance between 100% and 200% of the thickness of the flap. While a certain degree of offset may avoid introducing tension or deformation in the resulting container, limiting such offset may avoid or limit the likelihood of contents spilling through overlapping flaps in the resulting container.

[0029] In some examples, the container includes various pre-cut lines arranged in one or more fins. These pre-cut lines can be weak lines (compared to the material strength near them), which are intended to break when sufficient shear force is applied to the container. The pre-cut line may be present in a linear or curved segment of the fin (or panel) and may be formed by partially cutting the material. The partial cut may be in the thickness direction, that is, a portion of the thickness of the fin / panel has been cut. Therefore, the local thickness of the material at the pre-cut line is less than the local thickness around the pre-cut line. Alternatively, the pre-cut line may be formed by a dotted line running through the cut, thereby intermittently cutting through the entire thickness of the fin / panel. The pre-cut line may also include a combination of one or more partial cuts in the thickness direction and one or more interrupted lines running through the cut. Other techniques may be used to weaken the fin / panel in the pre-cut line.

[0030] In some examples, the first main wing may have a through opening. A through opening should be understood as a recess extending through the entire thickness of the wing and surrounded by a closed shape of the wing material (as opposed to a notch which would only be partially surrounded by material).

[0031] In some examples, the pre-cut line separates the proximal region of the flap from the distal region of the flap. The proximal region should be understood as a portion of the flap near or including the crease line. The distal region of the flap should be understood as a portion of the flap away from the crease line and including at least one free edge of the flap.

[0032] The resulting container, i.e., the container that can be obtained by the container blank of the present disclosure, should be understood as an object that contains contents, such as in the cavity of the container. The container together with its enclosed contents can form a consumer product. The container facilitates the protection, transportation, storage, access and handling of the consumer product.

[0033] In the present disclosure, consumer products should be understood as products that are especially provided to end consumers. Such consumer products can be purchased, for example, in supermarkets, and end consumers can store such consumer products at home. Consumer products can be provided in large quantities, and therefore environmental issues should be considered when designing products. The design of consumer products should also take into account the problem of transportation to retail stores. Consumer products should also be robust so as to withstand transportation as part of e-commerce shipments. The design of consumer products should also take into account shelf storage in retail stores. The design of consumer products should also take into account transportation from retail stores to consumer homes. The design of consumer products should also take into account storage in private end consumer homes. The design of consumer products should also take into account the use of consumer products in private end consumer homes. The design of consumer products should also take into account disposal.

[0034] Consumer products according to the present disclosure include detergent products. Detailed examples of the properties of detergent products are given below.

[0035] In some examples, the container includes a base. A base according to the present disclosure should be understood as a wall on which the container can be located when placed on a support surface such as a shelf or a floor. The base can be made of a plurality of flaps folded relative to the sidewalls so that those flaps forming the base lie flat or lie flat in substantially parallel planes in a substantially coplanar manner. 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 has an embossed profile that protrudes inwardly or outwardly in the form of a relief.

[0036] In the present disclosure, substantially should be understood to be within 10%, preferably within 5%, of the measurement in question, taking into account, for example, typical manufacturing tolerances. Two quantities are substantially equal to each other when they differ from each other by no more than 10%, preferably no more than 5%. A line is substantially oriented in a direction when it deviates from that direction by no more than 5°, preferably no more than 2°, more preferably no more than 1°.

[0037] In this disclosure, approximately should be understood to be within 10%, preferably within 5%, of the metric of interest, taking into account, for example, typical manufacturing tolerances.

[0038] In the present disclosure, ordinal labels "first", "second", "third", ..., "eighth" are used to distinguish features of a blank from one another. Thus, the first main panel is a different panel from the second main panel in the sense that the first and second main panels constitute two separate entities of the blank, although they may share similar dimensions or properties. A higher ordinal number (e.g., fourth) does not necessarily mean that a similar feature of a lower ordinal number (e.g., third) is part of an example container blank: for example, a container blank may include a fourth longitudinal crease line without including a second or third longitudinal crease line.

[0039] Detailed Description of the Drawings

[0040] In some examples, the container blank shown in the accompanying drawings may only form a part of a complete blank that will be used to build a container. Various elements of different accompanying drawings may be combined to form containers of various shapes. Similar numbers in each figure are intended to describe similar elements of the blank. The container blank or a portion thereof may be made of any suitable material. Examples of such materials are discussed in detail below. A coordinate system is introduced, in which the x-axis indicates the transverse direction, and the y-axis indicates the longitudinal direction. As will be apparent in the accompanying drawings, the longitudinal direction is the direction of the maximum dimension of the main panel. In other examples that are not illustrated here but are included in the scope of the present disclosure, the longitudinal direction may correspond to the shortest dimension of the main panel. As will be apparent, the fold line connecting the panel to the wing extends parallel to the transverse direction, while the fold line separating the panel from another panel extends parallel to the longitudinal direction.

[0041] In the accompanying drawings, the panel is represented as having a generally rectangular shape. However, as described above, the shape of the panel may have different properties. In addition, the fin is represented as being generally rectangular or trapezoidal. For the sake of clarity, these shapes are intended to present various aspects of the present disclosure in a schematic manner. However, those skilled in the art will know how to modify the general shape of the panel and fin without departing from the scope of the present disclosure. In particular, if the shape of the panel or fin is modified, the orientation of the longitudinal direction and the transverse direction may be appropriately changed.

[0042] Figures 1 to 9The blank is shown with a flap disposed only on one side of the panel. It should be noted that the container blanks 100 to 900 may be modified to have additional flaps at the opposite side of the drawn panel. In some examples, the container blank is symmetrical about the transverse axis x.

[0043] Figure 1 An example container blank 100 according to the present specification is illustrated. The container blank 100 comprises a main panel 102 and a main flap 106 separated from the main panel 102 by a main crease line 108 in a transverse direction. A coordinate system indicates the transverse direction x and the longitudinal direction y and is arbitrarily located at the center of the main panel 102.

[0044] The blank 100 also includes a secondary panel 112 directly connected to the main panel 102. The longitudinal fold line 104 separates the main panel 102 from the secondary panel 112. The secondary panel 112 has a size smaller than the size of the main panel 102. In some examples, the lateral width of the secondary panel 112 is at least one-third of the lateral width of the main panel 102 and is less than 100% thereof. The main panel 102 can have a lateral width included between 15cm and 60cm, preferably included between 18.5cm and 28.4cm. The second panel 112 can have a lateral width included between 5cm and 25cm, preferably included between 6.2cm and 14.5cm. Both panels can have a (corresponding) height included between 20cm and 70cm, and preferably included between 20.5cm and 50cm.

[0045] The secondary panel 112 supports a secondary flap 116 which is separated from the secondary panel 112 by a secondary fold line 118 in the transverse direction.

[0046] The main crease line 108 and the secondary crease line 118 are offset in the longitudinal direction y. Figure 1 The offset is arranged in such a direction that the longitudinal free edge portion 103 is formed on the primary panel 102 (rather than on the secondary panel 112). The longitudinal free edge portion has a length L1 equal to the distance D1. In some examples, the longitudinal length of the secondary panel 112 is less than the longitudinal length of the primary panel 102.

[0047] The distance D1 is comprised between 100% and 200% of the thickness e of the secondary wing 116 (as shown in the cross section A:A). In some examples, D1 is comprised between 110% and 150% of the thickness e. The thickness e may be comprised between 0.5 mm and 6 mm, preferably between 1.5 mm and 4 mm. The distance D1 may be comprised between 0.52 mm and 11.4 mm, preferably between 2 mm and 4 mm.

[0048] Once the flaps are folded, the offset makes the container spill-proof. Without being bound by theory, the offset can also maintain internal strain between the flaps, which can be beneficial to facilitate the opening of the container because the flaps will tend to open when the lock is released. As shown below, in some examples, the lock can be composed of a tab that releasably engages a tab receiver. In some examples, the container is made of a corrugated material including a groove extending in the longitudinal direction, and the tab is deformed perpendicular to the main direction of the groove. This can provide a memory effect for the deformation of the tab.

[0049] In the following description, the main panel 102 is the first main panel 102, the longitudinal free edge portion 103 is the first longitudinal free edge portion 103, the longitudinal fold line 104 is the first longitudinal fold line 104, the main wing 106 is the first main wing 106, the main fold line 108 is the first main fold line 108, the secondary panel 112 is the first secondary panel 112, the secondary wing 116 is the first secondary wing 116, the secondary fold line 118 is the first secondary fold line 118, the distance D1 is the first distance D1, and the length L1 is the first length L1.

[0050] Figure 2 An example of a container blank 200 is shown. The container blank 200 may include panels and flaps as presented in the previous figures. The container blank 200 also includes a second main panel 202, which is directly connected to the first primary panel 112 and separated from the first primary panel by a second longitudinal fold line 204. The second main panel 202 supports a second main flap 206, which is directly connected to the second main panel 202 and separated from the second main panel by a second main fold line 208. The size of the second main panel 202 can be substantially equal to the size of the first main panel 102. In some examples, the size of the second main flap 206 is substantially equal to the size of the first main flap 106.

[0051] The distance D2 shows the longitudinal offset between the second main crease line 208 and the first crease line 118. The second longitudinal free edge portion 203 of the second main panel 202 specifies the direction of the offset. The length L2 of the second longitudinal free edge portion 203 is equal to the distance D2. The distance D2 can be included in the thickness e of the secondary flap 116 (e.g. Figure 1The distance D2 may be between 50% and 100% of the thickness e). In some examples, D2 is included between 55% and 95% of the thickness e. When the blank is folded to form a container, the second main flap is intended to be folded over the secondary flap 116, and the first main flap 106 is intended to be folded over the second main flap 206. Therefore, the distance D2 may be less than the distance D1 while still ensuring an anti-spill arrangement. In some examples, the distance D2 is about half of the distance D1. The thickness e may be included between 0.5 mm and 6 mm, preferably between 1.5 mm and 4 mm. The distance D2 may be included between 0.26 mm and 5.7 mm, preferably between 1 mm and 2.5 mm.

[0052] Figure 3 An example container blank 300 is shown. The container blank 300 may include panels and flaps as presented in the previous figures. The container blank 300 also includes a secondary panel 302, which is directly connected to the second main panel 202 and separated from the second main panel by a third longitudinal fold line 304. The secondary panel 302 supports a secondary flap 306, which is directly connected to the secondary panel 302 and separated from the secondary panel by a second fold line 308. The size of the secondary panel 302 can be substantially equal to the size of the first panel 112. In some examples, the size of the secondary flap 306 is substantially equal to the size of the first flap 116.

[0053] The distance D3 shows the longitudinal offset between the second main crease line 208 and the secondary crease line 308. The third longitudinal free edge portion 303 of the second main panel 202 specifies the direction of the offset. The length L3 of the third longitudinal free edge portion 303 is equal to the distance D3. The distance D3 may be included in the thickness e of the secondary flap 116 (e.g. Figure 1 In some examples, D3 is comprised between 55% and 95% of the thickness e. The thickness e may be comprised between 0.5 mm and 6 mm, preferably between 1.5 mm and 4 mm. The distance D2 may be comprised between 0.26 mm and 5.7 mm, preferably between 1 mm and 2.5 mm.

[0054] In some examples, distance D2 is substantially equal to distance D3.

[0055] Figure 4 An example container blank 400 is shown. The container blank 400 may include panels and flaps as presented in the previous figures. Figure 4As shown in , in some examples, the longitudinal width w of the first main flap 106 and the second main flap 206 can be equal and can be equal to the transverse width w of the first secondary panel 112 and / or the second secondary panel 302. In such examples, the four panels 102, 112, 202, 302 can form a side wall of the container, thereby defining an opening, and the main flaps 106, 206 can substantially cover the entire such opening.

[0056] Figure 5 An example container blank 500 is shown. The container blank 500 may include panels and flaps as presented in the previous figures. Figure 5 The second main wing 506 is shown to have a distal edge 510 opposite to the second main panel 202. The distal edge 510 can be substantially parallel to the second main fold line 208. The distal region 512 of the second main wing 506 can be defined by a pre-cut line 513 and the distal edge 510. The distal region 512 and the pre-cut line 513 divide the distal edge 510 into a central section 514 and two lateral sections 516, 518 in the transverse direction. In some examples, the two lateral sections 516, 518 have the same length. In such examples, the length of the two lateral sections 516, 518 is equal to the longitudinal length of the secondary wing 116, 306. In some examples, the two lateral sections 516, 518 have different lengths. In such examples, the lengths of the two lateral sections 516, 518 are different and are respectively equal to the longitudinal length of the secondary wing 116, 306. Therefore, when the secondary flaps 116, 306 are folded along the secondary crease lines 118, 308 and when the second primary flap 506 is folded along the second primary crease line 208, the secondary flaps 116, 306 do not overlap the distal region 512. If the secondary flaps 116, 306 are designed to be adjacent to the pre-cut line 513, they can form a close arrangement.

[0057] Figure 6 Shows the composition Figure 5 An example container blank 600 of an alternative design of the design of . Figure 6 A design of may be preferred, in particular for smaller sized blanks, i.e., blanks having dimensions within the range described above with respect to Figure 1 Container blank in the lower half of the range discussed. The container blank 600 may comprise panels and flaps as presented in the previous figures. Figure 6It is shown that the secondary fins 616, 606 may have corresponding notches 617, 607, so that the overall length LT of these fins 616, 606 may be greater than the corresponding length L of the two lateral sections 516, 518, but the shortest length at the location of the notches 617, 607 may be substantially equal to the corresponding length L of the two lateral sections 516, 518. In other examples not illustrated here, the lateral sections 516 and 518 may have different lengths, and the notches 617 and 607 respectively have different sizes matching the corresponding different lengths so as to avoid overlapping with the distal region 512.

[0058] Figure 7 An example container blank 700 is shown. The container blank 700 may include panels and flaps as presented in the previous figures. Figure 7 The secondary flaps 716, 706 are shown to include pre-cut lines 710, 720 that divide the secondary flaps into proximal regions 712, 722 and distal regions 714, 724. The pre-cut lines 710, 720 extend substantially transversely. In some embodiments, the distal regions 714, 724 may be provided with an adhesive layer so as to adhere to the second primary flap 206 when the container blank is folded to form a container.

[0059] Figure 8 An example container blank 800 is shown. The container blank 800 may include panels and flaps as presented in the previous figures. Figure 8 It is shown that the first main wing 806 can be provided with two lateral edges 802, 803, a through opening 804, and two pre-cut lines 808, 810, which connect the through opening 804 to the lateral edges 802, 803, respectively. The pre-cut lines 808, 810 can be substantially linear, can be inclined, and / or can be curved. In some examples, the edge of the through opening 804 can form a tab 807, which the end user can pull to tear off the pre-cut lines 808, 810. The proximal region 812 of the first main wing 806 can thus be separated from the distal region 814 of the first main wing 806.

[0060] Fig. 9 An example container blank 900 is shown. The container blank 900 may include panels and flaps as presented in the previous figures. Fig. 9A container blank is shown having an auxiliary panel 902, which is directly connected to the first main panel 102 by a fourth longitudinal fold line 904. In some examples, the first to fourth longitudinal fold lines 104, 204, 304, 904 can be intended to form four vertical edges of a parallelepiped container. The auxiliary panel 902 can support an auxiliary flap 906, which is separated from the auxiliary panel by an auxiliary fold line 908. The auxiliary fold line 908 can be offset from the first main fold line 108 by a fourth distance D4. The fourth longitudinal free edge portion 903 of the first main panel 102 can have a length L4 equal to the fourth distance D4. The distance D4 can be included in the thickness e of the secondary flap 116 (such as Figure 1 In some examples, D4 is comprised between 110% and 150% of the thickness e. In some examples, D4 is substantially equal to D1. The thickness e may be comprised between 0.5 mm and 6 mm, preferably between 1.5 mm and 4 mm. The distance D4 may be comprised between 0.52 mm and 11.4 mm, preferably between 2 mm and 4 mm.

[0061] The auxiliary panel 902 may have a lateral width that is significantly smaller than the width of the auxiliary panels 112, 302 (e.g., at least five times smaller). The longitudinal width of the auxiliary flap 906 may be substantially equal to the longitudinal width of the auxiliary flap ( Figure 5 The L on Figure 6 LT on the upper side). Thus, the auxiliary flap can be long enough to create tension under the primary and secondary flaps (directly or indirectly). This will further improve the anti-spill properties of the container and will aid in the opening of the container because when the lock of the container is released, this will create a vertical force that assists the flap in opening. As shown below, in some examples, the lock can be composed of a tab that releasably engages a tab receiver.

[0062] It should be noted that although in the detailed example panels 902, 102, 112, 202 and 302 follow each other along direction y, many other configurations may be provided, such as, for example, panels 102, 112, 202, 302 and 902 may thereby follow each other along direction y, or, for example, panels 112, 202, 302, 102 and 902 may follow each other along direction y.

[0063] Fig.10 An example container blank 1000 is shown. The container blank 1000 may include the Fig. 91000. The container blank 1000 may include a third major flap 1006 connected to the first major panel 102 opposite the first major flap 106. A third major crease line 1108 separates the first major panel 102 from the third major flap 1006. The container blank 1000 may include a fourth major flap 1206 connected to the second major panel 202 opposite the second major flap 206. The fourth major crease line 1208 separates the second major panel 202 from the fourth major flap 1206. The container blank 1000 may include a tertiary flap 1116 connected to the first panel 112 opposite the first flap 116. The tertiary crease line 1118 separates the first panel 112 from the tertiary flap 1116. The container blank 1000 may include a fourth secondary flap 1306 connected to the second panel 302 opposite the second flap 306. The fourth secondary crease line 1308 separates the secondary panel 302 from the fourth flap 1306. The second auxiliary flap 1906 can be disposed opposite the first auxiliary flap 906. The second auxiliary crease line 1908 separates the auxiliary panel 902 from the second auxiliary flap 1906.

[0064] In some examples, the crease lines 1108, 1118, 1208, 1308, 1908 are all aligned, or at least the third main crease line 1108 and the fourth main crease line 1208 are aligned. In some examples, the crease lines 1108, 1118, 1208, 1308, 1908 are offset, such as Fig.10 As shown above. The fifth longitudinal free edge portion 1103, the sixth longitudinal free edge portion 1203, the seventh longitudinal free edge portion 1303 and the eighth longitudinal free edge portion 1903 define the directions of these offsets. These longitudinal free edge portions have corresponding lengths L5, L6, L7, L8, which respectively match the fifth offset distance D5, the sixth offset distance D6, the seventh offset distance D7 and the eighth offset distance D8 between two adjacent crease lines. In some examples, D6 is substantially equal to D7. In some examples, D5 is substantially equal to D8. In some examples, D6 and / or D7 is substantially equal to half of D5 or D8.

[0065] In some examples, fins 1006, 1116, 1206, 1306, and 1906 may be symmetrical to fins 106, 116, 206, 306, and 906, respectively. In some examples, fins 1006, 1116, 1206, and 1306 have the same Figures 4 to 8The symmetrically positioned fins 206, 306, 506, 606, 616, 706, 716, and 806 on the same may present similar features. Similarly, the offset distances D5, D6, D7, D8 and the lengths L5, L6, L7, L8 may correspond to the corresponding offset distances D1, D2, D3, D4 and the lengths L1, L2, L3, L4.

[0066] Fig.11 An example of a method for obtaining a container from one of the container blanks 100 to 1000 is illustrated.

[0067] In step 2010, a container blank according to any of the previous examples is provided.

[0068] This step may include a sub-step in which the panels are folded together along the longitudinal fold lines 104, 204, 304, 904. The auxiliary panel 902 may connect the first primary panel 102 to the secondary panel 306. To this end, glue or a similar adhesive element may be applied to the auxiliary panel 902 before folding the panels together along the longitudinal fold lines.

[0069] In step 2020, the secondary flaps 116, 306, 606, 706, 616, 716 are folded along the secondary crease lines 118, 308. The corresponding offset means that the folded secondary flap will at least partially fill the corresponding free edge portion with its thickness, thereby avoiding the generation or build-up of excessive tension in the resulting container. The offset and free edge portion described hereby actually create a volume in which the corresponding flap can be accommodated.

[0070] Steps 2030 to 2060 are optional because they relate to features of the container blank that were presented as optional in the examples above.

[0071] In step 2030, an adhesive element is applied to the distal regions 714, 724 of the first and second sub-flaps. The adhesive element may be at least one of: glue, staples, adhesive tape, clamps, etc. The proximal regions 712, 722 are substantially free of adhesive elements.

[0072] In step 2040 , the second primary flap 206 , 506 is folded over the secondary flap 116 , 306 , 606 , 706 , 616 , 716 . Fig. 12A The container being manufactured is shown in which the second major flap has been folded over the minor flap.When the adhesive element 730 has been applied to the distal regions, the second major flap adheres to these distal regions.

[0073] Return to reference Fig.11In step 2050, an adhesive element is applied to the distal region 512 of the second main wing. In step 2060, an adhesive element is applied to the proximal region of the second main wing mirroring the distal region 814 of the first main wing defined by the pre-cut lines 808, 810 and the through opening 804 of the first main wing.

[0074] In step 2070, the (first) primary flap 106, 806 is folded down along the (first) primary crease line 108 onto the secondary flap, and optionally onto the second primary flap that has been folded over the secondary flap. Fig. 12B The container is shown manufactured after the main flap 806 has been folded downwards.

[0075] Fig. 12B On the left hand side is shown the use of Fig.11 The container that can be partially manufactured and obtained by the method shown above. As shown on the right hand side, the container can be turned over. The container can then be filled with contents, for example, a detergent composition in the detergent composition discussed below. Then, foldable flaps 1906, 1116, 1206, 1306 are to close the container. Therefore, flaps 106, 116, 206, 306, 506, 606, 616, 706, 716, 806 constitute the base of the container when the container is filled. In some examples, the container is filled in an inverted position compared to the position in which the container will stand during use. This can, for example, allow a measuring spoon to be provided in the container, whereby before the contents of the container are placed, the measuring spoon is placed in an empty container, and then the container is provided to the user, wherein the spoon is presented on the top of the contents of the container. The container provided hereby may, for example, correspond to a container as described in one or more of the examples in patent application EP23192988.6, filed on August 23, 2023 in the name of the same applicant, entitled “Consumer products and methods for operating the same” and incorporated herein by reference.

[0076] In some examples, the container is filled with a detergent composition that is in direct contact with the material forming the blank described herein, thereby avoiding the use of additional materials such as a liner. The blank described herein actually allows the flap to be neatly folded via offset and matching free edge portions, thereby reducing or avoiding the generation of tension in the container structure, thereby reducing or avoiding breakage at or near the crease line.

[0077] FIG. 13A to FIG. 13C A method of opening a container is shown. Fig.13A A top view of an example of a container is shown. In this example, an end user can Fig.13AThe arrow drawn on the top of the container pulls the tab 807. This action will tear off the pre-cut lines 808, 810, and the proximal area 812 of the first main flap 806 remains attached to the first main panel (102, not visible on the left hand side of this figure), while the distal area 814 adheres to the second main flap folded under the first main flap. In some examples, the container is made of corrugated material including grooves extending in the longitudinal direction, and the tab is deformed perpendicular to the main direction of the grooves. This can provide a memory effect for the deformation of the tab.

[0078] Fig. 13B An example of a container is shown after the first main flap has been opened.Once the tab 807 is pulled, the pre-cut lines 808, 810 are separated into two pairs of mirrored torn edges 808a, 808b, 810a, 810b.

[0079] The tab receiver 207 disposed on the second main flap has been exposed by opening the first main flap. The tab receiver 207 can cooperate with the tab 807 to repeatedly open and close the container.

[0080] In this example, the distal region 512 of the second main wing 506 has been torn off from the second main wing 506 and adhered to the proximal region 812 of the first main wing. The recess 509 is produced by this separation. The recess 509 can be used as a handle for the end user to open the second main wing 506.

[0081] Once the user pulls open the second main wing 506, optionally by pulling the recess 509, the result is Fig. 13C Container 2400 shown above. While pulling the second main flap 506, the distal regions 714, 724 of the secondary flap adhered to the second main flap 506 are torn off from the proximal regions 712, 722 of the secondary flap, thereby providing a wide opening for the end user to access the contents 2402 enclosed in the container.

[0082] Material of container

[0083] As described in detail below, the container blank of the present disclosure can be made of paper material in part or in whole, such as the material selected from paperboard, cardboard, the laminate comprising at least one cardboard or cardboard layer. Cardboard or cardboard contain cellulose fiber material or its mixture. The material for making the container blank can contain other ingredients, such as colorant, protective varnish, surface enhancement coating, barrier coating, preservative, regenerated fiber material, plasticizer, UV stabilizer, oxygen barrier, fragrance barrier and moisture proof agent or their mixture. In some examples, in order to provide the desired tear resistance and strength, the cellulose fiber length is 0.1mm to 5mm, preferably in the range of 1mm to 3mm. In some examples, cellulose fiber comes from various sources, such as original softwood or hardwood, hemp, grass, corn, bagasse, sugarcane, bamboo and other, and / or comes from recycled paper and cardboard after the producer or after the consumer. The container blank can include the area of ​​external or internal printing. The container blank can be made, for example, by cardboard manufacturing. Suitable container manufacturing processes may include, but are not limited to, tube forming by gluing steps, folding or a mixture thereof from flat cardboard or cardboard sheets. The container blank may be opaque or may filter certain specific wavelengths, for example to protect the contents from the influence of external light. In some examples, the container blank is at least partially and in some specific examples entirely constructed of paper-based materials. Paper-based materials refer to materials comprising paper in this article. Without being bound by theory, "paper" should be understood as a material made of cellulose-based pulp. Cardboard can be made of paper-based materials, which have a thickness and rigidity that makes it not collapse under its own weight. Cardboard should be understood to include a single-layer material, and cardboard should be understood to include multiple paper-based material layers. In some examples, the paper-based material includes cardboard, cardboard or a mixture thereof, wherein preferably, cardboard includes cardboard, corrugated fiberboard or a mixture thereof. The corrugated fiberboard includes a series of grooves. Each groove can be understood as a channel. The grooves extend parallel to each other, and the groove direction is the direction of travel along each channel. Further details of the material forming the container blank are further given below.

[0084] The paper-based material can be a laminate comprising paper, cardboard or a mixture thereof, wherein in some examples, the cardboard comprises cardboard, corrugated fiberboard 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, polyvinyl alcohol or a mixture thereof. In some examples, the plastic material comprises a copolymer of a monomer from ethylene and vinyl alcohol, or EVOH. A barrier material can be used as at least another material. The barrier material can be biaxially oriented polypropylene, metallized polyethylene terephthalate or a mixture thereof. At least another material can include wax, cellulosic material, polyvinyl alcohol, silicon dioxide, casein-based material or a mixture thereof. In some examples, the paper-based composite comprises a paper-based composite of a fiber-based material greater than 50% by weight, preferably greater than 85% by weight, and more preferably greater than 95% by weight. In some examples, the barrier material can include a plastic material having a thickness between 10 microns and 60 microns. In some examples, the barrier material may include a plastic material having a thickness between 10 microns and 35 microns.The paper-based material may be a laminate.

[0085] In some examples, the inner surface of the container (i.e., one side of the blank) includes paperboard, cardboard or a mixture thereof, wherein in a specific example, the cardboard includes a laminate of cardboard, corrugated fiberboard and polyethylene (particularly LDPE) or a mixture thereof, and in some examples, the outer surface of the container (i.e., the other side of the blank) includes at least another material. Alternatively, the at least another material may also be laminated between two paper-based material layers (such as paperboard or cardboard layers according to the present disclosure). Without wishing to be bound by theory, the at least another material may serve as a barrier for the leakage liquid absorbed by the paper-based material facing the inner side of the container to prevent or reduce the contamination flow through the wall of the container. It has been found that other structures can effectively avoid leakage of contents or protect the contents from the influence of external fluids, such as from the influence of showers, sinks, or from the influence of handling containers with wet hands. The contamination of the container wall may be ugly to consumers, or may contaminate storage areas.

[0086] In some examples, the container blank is made from a paper-based material that includes at least another material laminated between two corrugated fiberboard layers.

[0087] In some examples, the material used for the container blank includes a core cardboard flute material disposed between two layers of conventional cardboard (or paperboard) and a polyethylene laminate.

[0088] Paperboard or cardboard layers according to the present disclosure may be made of or may include recycled material or recycled cellulose fibers. One side of the container blank may include a coating or varnish. Such a coating or varnish may help to waterproof the board or help to protect the contents (such as the encapsulated detergent composition) from UV light. The coating or varnish may also help to protect the outer surface of the container from contamination by the contents (e.g., the encapsulated detergent composition), for example, if the water-soluble unit dose detergent of the encapsulated liquid detergent composition leaks.

[0089] The coating or varnish on the inner surface can help prevent the contents from adhering to the inner surface, or prevent inks, colorants, fragrances, non-ionic substances, oils, greases and other ingredients from migrating from the contents into the board, or prevent inks or additives from migrating from the board to the contents. In some examples, a detergent-resistant varnish or coating can be applied to areas exposed to the contents.

[0090] As mentioned above, container blank can actually be made of paper or paperboard material, particularly rigid cardboard material, flexible cardboard material or their mixture.In some examples, the material forming container blank has a wall thickness greater than 220 microns and less than 3mm.In some examples, the material forming container blank has a thickness greater than 1mm and less than 2mm.In some examples, the material forming container is folded on itself, for example, to strengthen the part or the whole of box or lid.Container blank can be made of paper material, bio-based material, bamboo fiber, cellulose fiber, cellulose-based or fiber-based material or their mixture.Container blank can be made of the material comprising recycled material, for example, reclaim cellulose fiber-based material.In some examples, for the convenience of opening, lid can be separated completely from box when opening, and the weight of lid is less than 200g, preferably less than 100g, even more preferably less than 80g, and greater than 10g, more preferably greater than 30g, even more preferably greater than 40g, so as to obtain a sufficiently strong lid structure.

[0091] In some examples, the container blank is made of a corrugated cardboard layer, the corrugated cardboard layer includes grooves, and the grooves preferably extend parallel to the longitudinal direction y. This direction can be the vertical direction of the side wall of the resulting container. The grooves increase the strength of the container blank.
