Description

[0001] DESCRIPTIVE MEMORANDUM

[0002] SCOPE

[0003] The present invention relates to the manufacture of custom-made corrugated cardboard packaging and involves a method for assembling and joining two or more pieces of cardboard, sized to contain products without exceeding the required dimensions. The packaging allows for an orderly stacking pattern, optimizing material usage and achieving the ideal weight. All of this is accomplished without generating significant material waste during the process.

[0004] BACKGROUND

[0005] In logistics processes related to product storage and transportation, optimal space utilization, organization, and weight are crucial variables for process efficiency. However, some industries lack the ability to anticipate their order packaging requirements and face very tight shipping deadlines. E-commerce companies (such as Amazon®, Mercado Libre®, and others) are a prime example, where small products are often packaged in excessively large boxes. This generates operational and cost inefficiencies, as well as significant waste, undermining the sustainable image expected of businesses today.

[0006] The state of the art has sought solutions to optimize the transport of packaging, aiming to reduce its space and weight. For example, document JP2019023109 describes a paper box containing a laminated paper product. The box has a basis weight of 250 to 370 g / m², a paper thickness of 280 to 430 µm / sheet, a long side of 200 to 250 mm, a height of 40 to 65 mm along the stacking direction of the paper product, an annular shock value (RL) along the long side of the box defined in JIS-P 8126 of 500 to 800 N, and a weight (RL / t) of 1.7 to 2.5 N / µm. Document JP2019085167 describes a foldable corrugated cardboard case comprising two lower inner flaps and two lower outer flaps that form a bottom by folding, and two upper inner flaps and two upper outer flaps that form a lid by folding.Document JP2003146328 describes a corrugated cardboard box comprising a peripheral wall surrounding four sides and flaps projecting from the top and bottom ends of the four wall surfaces constituting the peripheral wall. At least one wall surface is covered by a flap or an adjacent wall surface. A pair of cut lines extending at a predetermined interval are provided on the cardboard box, and a gripping portion is formed between the cut lines.

[0007] Another solution is disclosed in document CN104670614, which describes an integrally formed packaging box. The packaging box is generally hexagonal in shape and consists of a box body and a receiving portion. The box body comprises a top lid, a bottom plate, a left panel, a right panel, a front panel, and a back panel, and is characterized in that: the box body is integrally formed with the receiving portion; the left panel is provided with a first inner lid portion; the right panel is provided with a second inner lid portion and a receiving portion; and the first inner lid portion is provided with a groove. The first and second inner lid portions are folded inwards to form an inner lid of the casing, and the receiving portion includes a first flap, a second flap, and a third flap that are folded in two steps.The first flap has a fixing hole and is positioned in the housing parallel to the bottom plate. The second and first flaps are folded inwards at 90° into the housing. Keeping the first folding portion parallel to the bottom plate, the third and second flaps are folded in a 90° direction and positioned in the housing against the bottom plate. The third edge of the flap is pressed against the right panel, so that the housing portion is box-shaped within the housing.

[0008] Document JP2008094434 describes a corrugated cardboard packaging box, where the bottom of a sleeve made of multi-layer corrugated cardboard and freely folded into a flat shape is closed by a bottom wall with an automatic locking system. Within the sleeve, four side walls, connected parallel to each other by vertical folds, are made of a five-layer corrugated cardboard sheet. The sleeve can be folded flat along a pair of diagonally opposite folds into its assembled form. The bottom wall is formed by pairs of bottom wall component plates glued to the lower edges of adjacent left and right side walls along a pair of vertical folds of the sleeve. When the sleeve is folded flat, the bottom wall component plates also fold along the diagonal folds.When the sleeve is assembled, the component plates of the lower wall extend to close the bottom of the sleeve.

[0009] However, all the described state-of-the-art solutions feature fixed packaging configurations, where it is not possible to adapt the packaging size, which can lead to waste of the material used.

[0010] SUMMARY OF THE INVENTION

[0011] The present invention proposes a method of manufacturing packaging which uses a sheet, preferably cardboard, and a roll or coil of single-sided cardboard.

[0012] The cardboard sheet is used to manufacture a first element of the packaging. This sheet comprises a plurality of slits near each of the outer edges of the sheet's width, thus forming the first element of the packaging.

[0013] The invention further comprises a second element manufactured from the single-layer cardboard roll or reel. This second element may alternatively correspond to a perimeter or outline predefined by the customer.

[0014] The only requirement for manufacturing the packaging is that the user first define and fix at least one measurement—either the length or width that is most frequently used in the packaging. This fixed measurement will define the distance between the grooves in the sheet metal to create the first element of the packaging.

[0015] The advantages of using this method are:

[0016] Reduced material loss compared to the traditional box.

[0017] Packaging weight optimization.

[0018] Packaging size optimization: Establishing a standard size (length or width) allows for better organization and use of warehouse and transport space. Properly utilizing the strength of the boxes by aligning their walls reduces inventory levels and space requirements in user facilities.

[0023] DETAILED DESCRIPTION OF THE INVENTION

[0024] As detailed below, the invention relates to a method of assembling packaging boxes (100) with a fixed dimension.

[0025] The packaging consists of a first element (1) and a second element (2). The first element (1) is preferably made from a sheet of cardboard (10). Depending on the user's needs, at least one fixed dimension is defined, which can be either the width or the length of the packaging. This fixed dimension will depend on the user's requirements, particularly considering the most common dimensions used in the packaging of the products to be transported.

[0026] Thus, to generate the first element (1), adjacent longitudinal zones are defined on the sheet (10). These zones are configured by a first dimension corresponding to a tab zone (A), which allows the packaging (100) to be closed; a zone with a fixed dimension (B); and a third zone (C) that corresponds to the width or length, depending on how dimension (B) has been defined. The zone with the fixed dimension (B) and the zone with dimension (C) are then repeated. Each zone is separated by a plurality of grooves (3) distributed longitudinally along the sheet (10), which allow for the corresponding fold. Additionally, depending on the customer's needs, at least one height is defined for each package. Once this height is defined, a cut is made transversely across the sheet to create a contour or perimeter for the package.

[0027] In the first mode, the user defines two fixed dimensions (B and C), that is, the width and length of the packaging (100). In this mode, the customer only needs to define the corresponding height, as shown in Figure 1.

[0028] In a second configuration, only one dimension is fixed. In this case, as shown in Figure 2, the first zone (A), corresponding to the tab area, and the fixed-dimension zone (B) are maintained. The third zone (C) can vary according to the client's needs, either in width or length. Likewise, the height of each package can vary depending on the user's requirements. Between each zone, there are multiple longitudinal slits (3) for folding the box. This alternative allows for cuts and slits to be made wherever the client requires, ensuring that the width or length adheres to the measurement that the system requires to be fixed (not altered) for its operation. This method offers the greatest flexibility for sizing the packaging on-site.In this way, each of the first elements (1) obtained are joined at their ends to configure a perimeter or outline of the packaging (Figure 4).

[0029] The second element (2) is obtained from a roll or reel (20) of single-layer or single-face cardboard. The roll or reel of single-layer cardboard (20) is sized and cut according to the measurements of the perimeter or outline of the packaging (100) configured by the first element (1). For this, a dimension (D) is determined, which can correspond to the width or length of the perimeter or outline, defining fold lines (4, 5), which in turn define areas (E) and (F) on the edges of the roll or reel (20), which form gluing tab areas, to glue the second element (2) to the respective outline or perimeter formed by the first element (1). At the longitudinal ends of the respective zones (E, F) cuts (6) are generated in the shape of a “V” as shown in Figure 3, which are spaced according to the width or length of the perimeter or contour, as opposed to dimension (D) (Figure 3).In this way, the second element (2) configures an enclosure that allows closing the perimeter or outline to configure the final packaging (100), as shown in Figure 4.
