Definitions
- the present invention relates to a storage and transportation box, which has a high compressive strength on all sides.
- boxes which are used for storing and/or transporting objects. These boxes are usually made from cardboard and comprise a hinged lid. Said lid normally is formed by four flaps, two upper flaps and two lower flaps.
- corrugated cardboard For stackable storage boxes and for shipping boxes it is usual to use corrugated cardboard for their reinforcement. However, this corrugated cardboard does not effectively reinforce against compression all the faces of the box.
- boxes formed from a sheet and provided with a hinged lid are disclosed in WO2008139420A1 and WO2012160543A1 , of the same holder as the present application.
- WO2008139420A1 discloses a storage and transportation carton whose lid comprises inner flaps and outer flaps, the outer flaps being engageable with each other.
- the box disclosed in this document comprises a bottom formed by four sectors joined together which allow to fold and unfold the bottom automatically upon folding or unfolding the box, but it does not provide resistance to side compression in all directions because of this configuration of the box bottom.
- WO2012160543A1 discloses a storage and transportation and shipping box, comprising a first pair of flaps, the ends of which are substantially in contact with each other, or are overlapping with each other, and a second pair of flaps engageable with each other.
- the first flaps and the second flaps can be used as inner flaps.
- the box is used for storage, the first flaps are the inner flaps and the box is closed by the coupling of the second flaps, and if the box is used for shipping, the second engageable flaps are the inner flaps, and the box is closed using an additional closure element, e.g. an adhesive tape, on said first flaps.
- an additional closure element e.g. an adhesive tape
- the bottom of the carton is not disclosed, so that it may be a conventional bottom, which does not provide lateral compression resistance precisely in the area around said bottom.
- the storage and transportation box according to the present invention is formed from a sheet of corrugated material, said corrugated material defining a plurality of channels parallel to each other, said box comprising:
- said engageable flaps are the inner flaps of the bottom and/or of the lid, but they could also be the outer flaps.
- the fold lines separating the lid from the side walls could be aligned with each other.
- the fold lines separating the bottom from the side walls could be aligned with each other.
- channels are understood to mean the channels of the corrugated material, for example, corrugated cardboard or plastic, and these channels extend from the lid to the bottom, and they are preferably orthogonal to the lid and to the bottom, although in some cases they can extend between the lid and the bottom forming an inclined angle with respect to the lid and the bottom.
- this arrangement of the channels in the side walls also determines the arrangement of the channels in the lid and the bottom.
- the coupling of the lid and/or bottom flaps is performed by one or more slots connected to the flap edge, with one end of the slot open in the edge region, and another end closed inwardly of the flap.
- the closed inner ends of the oppositely engageable flaps are configured to substantially contact each other in a closed position. This way, it is possible to increase the lateral and vertical compression of the box as a whole.
- said outer lid and/or bottom flaps are overlapped with each other.
- said flaps are with their edges facing to each other in their closed position.
- the box is very resistant in all its faces, i.e., in the lid, the bottom and the side walls, irrespective of the position in which it travels.
- Another advantage obtained with the box of the present invention is that the bottom has greater resistance to the weight of the contents, because the engageable inner flaps define a central zone with double thickness.
- said channels of the corrugated material of the inner flaps are substantially perpendicular to the channels of the corrugated material of the outer flaps, since the box is formed from a single sheet.
- the side walls offer a resistance to vertical compression when several boxes are stacked together thanks to the vertical or diagonal arrangement of the channels of the corrugated material.
- the side walls also exhibit a resistance to side pressures, since the engageable inner flaps substantially prevent lateral compression and the edges of the inner flaps also contact the inner side of the side walls from which the outer flaps extend.
- the presence of a double thickness of corrugated material in the lid and the bottom allows a cutting element to be used to open the box when the outer flaps are closed with an adhesive tape without damaging the products inside the box.
- Another advantage of having internal flaps engageable in the lid and the bottom is that the inside of the box cannot be improperly accessed before opening the carton, unlike the conventional boxes, in which the inner tabs are spaced apart to each other.
- said inner lid flaps and/or said inner bottom flaps comprise at least one coupling slot, defining at least two flanges.
- one of said flanges is longer than the other.
- the engageable bottom and lid flaps incorporate 2, 3 and 4 engagement slots, defining 3, 4 and 5 flanges respectively, at least one of which flanges having a length greater than the rest to make the coupling easier and more robust.
- the incorporation of two or more coupling slots is especially interesting in boxes for storing or transporting elements of a remarkable length (for example, skis, golf clubs, rackets, lamps, curtains, etc.), since the multiple slots allow to distribute and to reinforce the locking mechanism along the entire length of the box.
- the longer flanges will extend substantially beyond the intermediate closure line in closed configuration for reinforcing by a double layer both the coupling and locking mechanism, as well as the compressive strength on the bottom or lid.
- the flanges of greater and smaller length are preferably sequentially alternated along the edge to facilitate and reinforce the coupling mechanism at the same time.
- the inner flaps of the bottom and/or the lid are connected with the outer flaps of the bottom and/or the lid by means of joining sectors.
- said joining sectors are triangular and define a fold line in the inner flaps.
- said triangle defined by each joining sector is a right triangle with its sides of equal length.
- the outer flaps of the lid and/or the bottom of the box preferably comprise a closure member, for example, a double-sided tape and/or glue, or a flange in the outer flaps which is introduced in a complementary housing of the inner flaps.
- a closure member for example, a double-sided tape and/or glue, or a flange in the outer flaps which is introduced in a complementary housing of the inner flaps.
- Said closure element by projection and slot or complementary housing is also used, in some of the embodiments of the invention, as an engaging element in the engageable flaps.
- said outer flaps may comprise at least one tearable strip for facilitating the opening of the box.
- some embodiments of the storage and transportation box according to the present invention comprise two handle-like holes on two opposing side faces.
- a box according to the present invention is formed from a single sheet of corrugated material, preferably corrugated cardboard, defining a plurality of channels substantially parallel to each other.
- the box of the present invention may be used for storage and/or transportation of products, i.e., it requires strength characteristics to prevent the products from being damaged during the use of the box, which is also stackable.
- FIG. 1 A first embodiment of the box according to the present invention is shown in Figures 1 to 6 .
- the box is formed from a corrugated cardboard sheet 1 which in its mounting position defines a lid 10, a bottom 11 and four side walls 12, 13.
- the lid 10 is formed by two pairs of flaps, inner flaps 2 and outer flaps 3, which extend hingedly respectively from opposite side walls 12, 13.
- the bottom 11 is also formed by two pairs of flaps, inner flaps 4 and outer flaps 5, which also extend hingedly respectively from opposite side walls 12, 13.
- said inner flaps 2, 4 of the lid 10 and the bottom 11 are engageable with each other, i.e. they comprise at least one slot 7 defining at least two flanges 8, 9, which in the assembly position are overlapped with each other.

- the orientation of the channels of the corrugated material is vertical in the side walls 12, 13 in their use position, or such channels may be diagonally inclined. Further, since the box is formed from a single sheet, this implies that the channels of corrugated material in the inner flaps 2, 4 of the lid 10 and the bottom 11 are substantially perpendicular to the channels of corrugated material in the flaps 3, 5 of the lid 10 and the bottom 11, reinforcing them.

Abstract
The box is formed from a sheet of corrugated material, said corrugated material defining a plurality of channels parallel to each other, said box comprising a lid (10), comprising two inner flaps (2) and two outer flaps (3), two of said flaps of the lid (10) being engageable with each other; a bottom (11); and four side walls (12, 13), in which the channels of the corrugated material are vertical or inclined in the use position of the box; wherein said bottom (11) comprises two inner flaps (4) and two outer flaps (5), two of said flaps of the bottom (11) being engageable with each other. It permits the box to have a high compressive strength on all sides.
Description
- The present invention relates to a storage and transportation box, which has a high compressive strength on all sides.
- There are known boxes which are used for storing and/or transporting objects. These boxes are usually made from cardboard and comprise a hinged lid. Said lid normally is formed by four flaps, two upper flaps and two lower flaps.
- These already known storage boxes are normally formed from a sheet provided with several fold lines, so that by a mounting process the box is obtained, and it is ready for use.
- For stackable storage boxes and for shipping boxes it is usual to use corrugated cardboard for their reinforcement. However, this corrugated cardboard does not effectively reinforce against compression all the faces of the box.
- Examples of boxes formed from a sheet and provided with a hinged lid are disclosed in
WO2008139420A1 andWO2012160543A1 , of the same holder as the present application. -
WO2008139420A1 discloses a storage and transportation carton whose lid comprises inner flaps and outer flaps, the outer flaps being engageable with each other. - The box disclosed in this document comprises a bottom formed by four sectors joined together which allow to fold and unfold the bottom automatically upon folding or unfolding the box, but it does not provide resistance to side compression in all directions because of this configuration of the box bottom.
-
WO2012160543A1 discloses a storage and transportation and shipping box, comprising a first pair of flaps, the ends of which are substantially in contact with each other, or are overlapping with each other, and a second pair of flaps engageable with each other. Depending on their use, the first flaps and the second flaps can be used as inner flaps. Thus, if the box is used for storage, the first flaps are the inner flaps and the box is closed by the coupling of the second flaps, and if the box is used for shipping, the second engageable flaps are the inner flaps, and the box is closed using an additional closure element, e.g. an adhesive tape, on said first flaps. - In this document the bottom of the carton is not disclosed, so that it may be a conventional bottom, which does not provide lateral compression resistance precisely in the area around said bottom.
- It is therefore an object of the present invention to provide a reinforced storage and transportation box, in which all the faces of the carton, i.e. the lid, the bottom and the four side walls, are reinforced and have a large resistance to compression, compared to conventional boxes.
- With the storage and transportation box of the invention said disadvantages are solved, presenting other advantages that will be described below.
- The storage and transportation box according to the present invention is formed from a sheet of corrugated material, said corrugated material defining a plurality of channels parallel to each other, said box comprising:
- a lid on the upper face, comprising two inner flaps and two outer flaps, two of said flaps being engageable to one another;
- a bottom on the lower face; and
- four side walls, in which the channels of the corrugated material are vertical or inclined in the use position of the box;
- Preferably, said engageable flaps are the inner flaps of the bottom and/or of the lid, but they could also be the outer flaps.
- To enable the inner flaps or the outer flaps of the lid to engage, the fold lines separating the lid from the side walls could be aligned with each other.
- Likewise, to enable the inner flaps or the outer flaps of the bottom to engage, the fold lines separating the bottom from the side walls could be aligned with each other.
- It should be noted that in the present description and in the claims the "channels" are understood to mean the channels of the corrugated material, for example, corrugated cardboard or plastic, and these channels extend from the lid to the bottom, and they are preferably orthogonal to the lid and to the bottom, although in some cases they can extend between the lid and the bottom forming an inclined angle with respect to the lid and the bottom. In addition, it should also be noted that as the box is formed from a single sheet, this arrangement of the channels in the side walls also determines the arrangement of the channels in the lid and the bottom.
- Preferably, the coupling of the lid and/or bottom flaps is performed by one or more slots connected to the flap edge, with one end of the slot open in the edge region, and another end closed inwardly of the flap. In some preferred embodiments, the closed inner ends of the oppositely engageable flaps are configured to substantially contact each other in a closed position. This way, it is possible to increase the lateral and vertical compression of the box as a whole.
- Advantageously, in some embodiments of the invention, said outer lid and/or bottom flaps are overlapped with each other. In other embodiments, said flaps are with their edges facing to each other in their closed position.
- Thanks to this feature, the box is very resistant in all its faces, i.e., in the lid, the bottom and the side walls, irrespective of the position in which it travels.
- In addition, it allows a reinforced structure expending the minimum cardboard, avoiding access to the interior of the box because the inner engageable flaps provide greater resistance in the central part.
- On the other hand, the closure of the outer flaps does not damage the engageable inner flaps, being reusable.
- Another advantage obtained with the box of the present invention is that the bottom has greater resistance to the weight of the contents, because the engageable inner flaps define a central zone with double thickness.
- At the lid and the bottom, said channels of the corrugated material of the inner flaps are substantially perpendicular to the channels of the corrugated material of the outer flaps, since the box is formed from a single sheet.
- The side walls, on the other hand, offer a resistance to vertical compression when several boxes are stacked together thanks to the vertical or diagonal arrangement of the channels of the corrugated material. In addition, the side walls also exhibit a resistance to side pressures, since the engageable inner flaps substantially prevent lateral compression and the edges of the inner flaps also contact the inner side of the side walls from which the outer flaps extend.
- In addition, the presence of a double thickness of corrugated material in the lid and the bottom allows a cutting element to be used to open the box when the outer flaps are closed with an adhesive tape without damaging the products inside the box.
- Another advantage of having internal flaps engageable in the lid and the bottom is that the inside of the box cannot be improperly accessed before opening the carton, unlike the conventional boxes, in which the inner tabs are spaced apart to each other.
- According to a preferred embodiment, said inner lid flaps and/or said inner bottom flaps comprise at least one coupling slot, defining at least two flanges. In addition, to facilitate coupling, one of said flanges is longer than the other. In some preferred embodiments, the engageable bottom and lid flaps incorporate 2, 3 and 4 engagement slots, defining 3, 4 and 5 flanges respectively, at least one of which flanges having a length greater than the rest to make the coupling easier and more robust. The incorporation of two or more coupling slots is especially interesting in boxes for storing or transporting elements of a remarkable length (for example, skis, golf clubs, rackets, lamps, curtains, etc.), since the multiple slots allow to distribute and to reinforce the locking mechanism along the entire length of the box.
- In some embodiments, the longer flanges will extend substantially beyond the intermediate closure line in closed configuration for reinforcing by a double layer both the coupling and locking mechanism, as well as the compressive strength on the bottom or lid. In those embodiments in which they include a plurality of slots and flanges, the flanges of greater and smaller length are preferably sequentially alternated along the edge to facilitate and reinforce the coupling mechanism at the same time.
- In some cases, the inner flaps of the bottom and/or the lid are connected with the outer flaps of the bottom and/or the lid by means of joining sectors. For example, said joining sectors are triangular and define a fold line in the inner flaps.
- According to a preferred embodiment, said triangle defined by each joining sector is a right triangle with its sides of equal length.
- In addition, in some embodiments, the outer flaps of the lid and/or the bottom of the box preferably comprise a closure member, for example, a double-sided tape and/or glue, or a flange in the outer flaps which is introduced in a complementary housing of the inner flaps. Said closure element by projection and slot or complementary housing, is also used, in some of the embodiments of the invention, as an engaging element in the engageable flaps.
- In some embodiments of the storage and transportation box according to the present invention, said outer flaps may comprise at least one tearable strip for facilitating the opening of the box.
- For ease of handling, some embodiments of the storage and transportation box according to the present invention comprise two handle-like holes on two opposing side faces.
- For better understanding of what has been disclosed, some drawings in which, schematically and only by way of a non-limiting example, some embodiments of the present invention are shown.

Figure 22 is a plan view of an engageable flap, comprising two slots and three flanges. - Firstly, it is indicated that a box according to the present invention is formed from a single sheet of corrugated material, preferably corrugated cardboard, defining a plurality of channels substantially parallel to each other.
- The box of the present invention may be used for storage and/or transportation of products, i.e., it requires strength characteristics to prevent the products from being damaged during the use of the box, which is also stackable.
- A first embodiment of the box according to the present invention is shown in
Figures 1 to 6 . - According to this first embodiment, the box is formed from a
corrugated cardboard sheet 1 which in its mounting position defines alid 10, a bottom 11 and fourside walls - The
lid 10 is formed by two pairs of flaps,inner flaps 2 andouter flaps 3, which extend hingedly respectively fromopposite side walls - The bottom 11 is also formed by two pairs of flaps,
inner flaps 4 andouter flaps 5, which also extend hingedly respectively fromopposite side walls - According to the embodiment shown, said
inner flaps lid 10 and the bottom 11 are engageable with each other, i.e. they comprise at least oneslot 7 defining at least twoflanges flanges - However, it should be noted that such engageable flaps could also be the
outer flaps lid 10. - To enable the inner flaps or the outer flaps of the
lid 10 to engage, the fold lines separating thelid 10 from theside walls - Likewise, to enable the inner flaps or the outer flaps of the bottom 11 to engage, the fold lines separating the bottom 11 from the
side walls - The
inner flaps 4 of the bottom 11 define, in their closed position, a substantially flat surface. - In some embodiments, the
inner flaps outer flaps corresponding side wall 12, in thelid 10 and the bottom 11, although in other cases, they are joined by joiningsectors 14. - In the embodiment shown, the
inner flaps 4 of the bottom 11 are attached to theouter flaps 5 by said joiningsectors 14, and theinner flaps 2 of thelid 10 could also be attached to theouter flaps 3 of thelid 10, although not shown in the figures. - Moreover, the inner and
outer flaps 5 of the bottom 11 could be devoid of said joiningsectors 14, as shown for thelid 10 in the figures. - Said joining
sectors 14 are preferably triangular, in particular, defining a right triangle with its sides of equal length. - It should be noted that two opposing
side walls 13 comprise, in some embodiments, handle-like holes 15, for facilitating the handling of the box. - The orientation of the channels of the corrugated material is vertical in the
side walls inner flaps lid 10 and the bottom 11 are substantially perpendicular to the channels of corrugated material in theflaps lid 10 and the bottom 11, reinforcing them. - Next, the process of mounting the box according to the present invention will be described.
- Firstly, a
fastening flange 16 is attached to theopposite side wall 13 in the carton manufacturing plant itself. In this configuration, the box, in its disassembled position, is completely flat, so that it occupies a reduced space for transportation before filling it with products. - When it is desired to use the box, it is placed in the position shown in
figure 2 , with itslid 10 and its bottom 11 open. The closure of thelid 10 and the bottom 11 may be carried out in any order, although the closure of the bottom 11 is first shown in the figures. - To do this, first the foldable
inner flaps 4, as shown infigure 3 , are folded towards the inside of the box. - According to this embodiment, since the
outer flaps 5 are attached to theinner flaps 4 by the joiningsectors 14, this folding of theinner flaps 4 will also cause the folding of the outer flaps 5. - During the folding of the
inner flaps 4, they engage each other through theslot 7, theflanges flanges flaps 4 are closed without the necessity of using an additional closing element. - To close the bottom 11, according to the embodiment shown, an additional closing element is used for the
outer flaps 5, such as an adhesive tape or staples. To this end, theouter flaps 5, in their closed position, have their opposite ends substantially in contact with each other, there being a slight separation, separated or totally or partially overlapped, so that it is possible to position said additional closing element. - The closure of the
lid 10 is similarly performed, firstly folding theinner flaps 2, engaging each other in the same manner and then folding theouter flaps 3 for closing them with an additional closing element, for example an adhesive tape or staples. - As in the case of the
outer flaps 5 of the bottom 11, theouter flaps 3 of thelid 10, in their closed position, also have their opposite ends substantially in contact with each other, there being a slight gap, or being totally or partially overlapped, so that it is possible to place said additional closing element. - As indicated above, a box according to the present invention provides a reinforced box, which has a high strength in the lid, the bottom and the side walls against external forces towards the interior of the box.
- In
Figures 7 to 15 different embodiments of a box according to the present invention are shown. - For simplicity and clarity reasons, the same reference numbers are used to identify the same components of the box in all embodiments. In addition, only the differences with respect to the first embodiment previously disclosed are described for the sake of simplicity.
- In the embodiment shown in
Figure 7 , the difference with respect to the first embodiment is the presence of aclosing element 17 in theouter flaps 3 of thelid 10. Saidclosure element 17 is a double-sided tape or glue, or any other suitable element, for example, a projection on the outer flaps which is introduced into a housing complementary to the inner flaps. - In this embodiment, to facilitate the opening, the
outer flaps 3 also comprise atearable strip 6, which may be formed from a pre-cut strip in the flaps themselves or by an additional strip, for example of plastic material. - As seen in
figure 7 , in this embodiment, theouter flaps 3 of thelid 10 are somewhat longer than in the previous embodiment, so that they overlap each other, in this case partially, although it could overlap completely. - The assembly of the box in this embodiment is the same as that previously described, as can be seen in
figure 16 . The difference is when the box is closed, as it is performed by said closingelement 17, and when the box is opened, which is performed by saidtearable strip 6, as can be seen infigure 17 . - It should be noted, however, that, even if the
tear strip 6 is used, theouter flaps 3 of thelid 10, after a first opening, may be resealed by an additional closing element, such as an adhesive tape or staples. - In
figure 8 a further embodiment of the box according to the present invention is shown. This embodiment is very similar to the embodiment offigure 7 , the only difference being the presence also of theclosing element 17 and thetearable strip 6 in theouter flaps 5 of the bottom 11. - Assembly, closure and opening are the same as in the previous embodiment.
- In
figure 9 a further embodiment of the box according to the present invention is shown. With respect to the first embodiment previously described, the difference is the presence of joiningsectors 14 also between theinner flaps 2 and theouter flaps 3 of thelid 10, their function being the same as the joining sectors previously described. - In

With respect to the first embodiment previously described, the difference is that the joiningsectors 14 in the bottom 11 are not present, theinner flaps 4 andouter flaps 5 of the bottom 11 being the same as theinner flaps 2 andouter flaps 3 of thelid 10. - In
figure 13 a further embodiment of the box according to the present invention is shown. With respect to the above embodiment, the difference is the presence of theclosing element 17 and thetearable strip 6 in theouter flaps 3 of thelid 10. - In
figure 14 a further embodiment of the box according to the present invention is shown. With respect to the previous embodiment, the difference is the presence of theclosing element 17 and thetearable strip 6 also in theouter flaps 5 of the bottom 11. - In
figure 15 a further embodiment of the box according to the present invention is shown. This embodiment is similar to the embodiment offigure 12 , except that theouter flaps lid 10 and of the bottom 11 are also engageable, i.e. they comprise at least oneslot 7 defining a pair offlanges inner flaps - In this case, it is not necessary to use a closing element in the outer flaps themselves or an additional closing element, since the
outer flaps flanges figure 18 , where theinner flaps 2 of thelid 10 can be seen in their closed position and theouter flaps 3 opened. - In
figures 19 and20 two boxes are shown according to the present invention where different portions of the side walls and the lid have been cut out to show the channels of the corrugated material. - In
figure 19 said channels are vertical in the side walls in the use position, whereas infigure 20 said channels are inclined in the side walls in the use position. -
Figure 21 shows an embodiment of an engaging system between theinner flaps 2 and theouter flaps 3, comprising at least oneflange 8 on theouter flap 3 that is housed in aslot 7 complementary to theinner flap 2. - It should be noted that this coupling system can be used in the
lid 10 and/or in the bottom 11 of the box and that, although twoflanges 8 and twoslots 7 are shown in this figure, the engagement can also be done with asingle flange 8 or with more than twoflanges 8. -
Figure 22 shows an embodiment of an engageable flap comprising twoslots 7 and threeflanges lid 10 and/or of the bottom 11. - Although reference has been made to several specific embodiments of the invention, it is evident for a person skilled in the art that the described storage and transportation box is susceptible to numerous variations and modifications, that all the mentioned details can be replaced by other technically equivalent ones, and that the features described in different embodiments may be combined with each other, without departing from the scope of protection defined by the appended claims.
