Description

DESCRIPTION

POLYGONAL CONTAINER OF CORRUGATED LAMINAR MATERIAL AND PLATE OF CORRUGATED AND DROPPED LAMINAR MATERIAL FOR THE OBTAINING OF THE SAME

Field of technique

The present invention concerns the field of polygonal containers of corrugated sheet material, also describing the sheet of corrugated sheet material punched and split for obtaining said container by folding and folding operations of said sheet.

The proposed package is preferably dedicated to containing an airtight bag for storing and dispensing liquid or granular products, especially of the type known in the industry as "bag-in-box", although other applications than the container proposed are also contemplated.

State of the art

The use of polygonal containers made from a band of corrugated sheet material, typically corrugated cardboard, rolled on itself to form a tubular body is widely known.

So is the use of said containers to contain hermetic bags for storage and dispensing of liquid or granulated products through a dispensing device connected to said sealed bag and accessible from the outside of the container through an opening made in said container. This type of packaging is commonly known in the industry as "bag-in-box".

DE3411607A1, WO2005019063A1, US4850506A and EP1762502A1 are four examples describing packages of this type. All of them are prismatic containers, that is to say that all their lateral faces are rectangular, their two ends identical, and their constant section, for example hexagonal or octagonal prism form.

This type of containers are typically used for the marketing of wines and other spirits that require barrel aging, so often said containers are intended to reproduce the appearance of a barrel by its shape and printed motifs that are included in its surface , often resorting to print of wooden slats on its sides, however the prismatic shape does not resemble too much the shape of a barrel, so the resemblance is scarce.

In addition, a constant-section container has large caps, the lid being the weakest and most difficult to produce container, its size increases its cost and manufacturing difficulty.

Document EP3321202A1 is also known, which describes a container with a generally tapered shape, much more similar to the shape of the barrels than the prismatic form of the previous examples, however in this case the aforementioned container is made from real wooden rings. connected to each other by staves also made of real wood, forming two cup-shaped halves that, once joined, form in a barrel-shaped container intended to contain the hermetic bag.

This document has a very laborious and expensive construction, hardly industrializable, and that undoubtedly has a much higher cost than other alternatives based on the use of a band of corrugated sheet material conveniently cut, folded and adhered.

Therefore, it is concluded that there is no known container that has the manufacturing, economic and ecological advantages of the containers made from a band of corrugated sheet material folded and bonded, and that at the same time offers the aesthetic benefits of a container with a general tapered geometry similar to that of a barrel.

BRIEF DESCRIPTION OF THE INVENTION

The present invention concerns, according to a first aspect of the present invention, a polygonal package of corrugated sheet material for a sealed bag for storing and dispensing liquid or granular products.

The proposed package comprises, in a manner known in the state of the art:

● a tubular body with three or more elongated walls joined laterally in succession through edge areas including folds, and with a first end and a second opposite end defined by a first end edge and a second end edge of the walls, the tubular body formed by a band of rolled corrugated sheet material, partially adhered on itself, forming a closed envelope;

● at least one cover attached to the tubular body sealing the first end and / or the second end;

That is to say that the proposed packaging is formed from a band of corrugated sheet material, typically corrugated cardboard, which is rolled on itself joining its two ends, for example by means of flaps, forming a closed envelope in the form of a hollow tubular body. To produce the winding of the band of corrugated sheet material a plurality of folds transverse to said web of sheet material are arranged, said folds being preferably parallel to a longitudinal central axis of the formed tubular body. Said folds will define corners of the tubular body.

The band of corrugated sheet material, after its rolling, will form elongated segments comprised between the transverse folds, which cover the entire height of the resulting tubular body, each of which has been called a wall. A container provided with, for example, three walls will form a tubular body with a triangular cross section (transverse to said longitudinal central axis), if it has six walls, it will form a container with a hexagonal cross section, etc.

The walls will be laterally joined in continuity with each other through said folds, that is to say they are cover parts obtained from the same band of corrugated sheet material that forms the tubular body and delimited through said folds. It is also proposed that one or both ends of the tubular body be closed by a cover, preferably also made of corrugated sheet material.

The present invention also proposes the following in a way that is not known by the state of the art:

● each wall comprises a first end portion, adjacent to the first end edge, and a second end portion, adjacent to the second end edge, where

● at least some of the first end portions and at least some of the second end portions are flat and trapezoidal in shape with one side defining the first end edge or the second end edge, and with two side sides connected to other adjacent walls of the tubular body through flaps located in the edge areas, defining a cross section of the decreasing container in approximation to the first and second ends, providing the container with a tapered shape.

That is, it is proposed that each of the walls that make up the tubular body be divided into at least two portions, a first end portion containing the first end edge of the wall, and a second end portion containing the second end edge of the wall. Wall.

Of all the first end portions arranged around the first end of the tubular body, it is proposed that at least some of them, or preferably all of them, have a trapezoidal or trapezoidal shape. In the case that only some of them have a trapezoidal or trapezoidal shape, the rest will preferably have a rectangular or square shape.

The first trapezoidal or trapezoidal end portions will have a side corresponding to the first end edge of the wall, another opposite side connected to the rest of the wall, and two lateral sides connected to other first adjacent end portions, of adjacent walls of the tubular body.

The length of the side corresponding to the first end edge will be less than the length of the opposite side of the first end portion, determining a reduction of the width of said first end portion in approximation to the first end edge. In forming the tubular body, laterally joining the lateral sides of each first end portion with the side flanks of other first adjacent end portions produces a tubular body with a variable decreasing section approaching the first end at said first end portion.

For example, if all the first end portions are trapezoidal, then a tubular body with a truncated-pyramidal end is generated.

To obtain said geometry from a flat plate in the form of a strip of corrugated sheet material, it is necessary to use flaps to join the lateral sides of the first trapezoidal or trapezoidal end portions with the first adjacent end portions by means of adhesive.

The same explanation is applicable to the second end portion, so that the container obtained will have a tubular body that, at both ends, will have a waning section geometry in approximation to the end, said container being therefore wider in the area central than in the extreme zones.

The result obtained is a container with a tapered shape, similar to a barrel, barrel or polygonal rugby ball. The greater the number of walls that make up the tubular body, the greater the similarity with these geometries.

Other geometries are also possible, for example by making asymmetric in container being the first end portion and the second end portion of different lengths, or making the first end and the second end of the tubular body of different diameters.

According to a preferred embodiment the container will have eight walls, thus improving the storage density of said containers, although it is also contemplated to have six or ten walls. In general, the use of an even number of walls greater than four is considered preferred.

According to a further proposed embodiment, said flaps located in at least one of the edge areas that laterally connect two adjacent walls correspond, in at least one edge area, to a flap joined in continuity with one of the two adjacent walls through a flap. fold and adhere to the intrados of the other adjacent wall. That is to say that between two first or two second adjacent end portions will be included a flap joined in continuity with one of said adjacent end portions, ie forming part of the same band of corrugated sheet material and delimited only by a fold, and glued to the soffit of the other adjacent extreme portion.

Alternatively or additionally, it is contemplated that the flaps located in the edge areas that laterally connect the adjacent walls correspond, in at least one edge area, to two preferably symmetrical flaps, each one joined in continuity with one of the walls through one of the walls. folding and joined together also in continuity through another fold or separated one from the other by a cut, the two flaps being opposite and adhered to each other. According to this embodiment, there is no cut of the band of corrugated sheet material between two first or second trapezoidal or trapezoidal adjacent end portions, since the entire intermediate space constitutes two flaps which, by folding, can collapse facing and gluing both flaps.

Preferably said flaps will remain, after being stuck, contained within the tubular body.

According to another provided embodiment, each wall comprises, in addition to the first and second end portions, a central portion comprised between the first and second end portions, said central portion of each wall being rectangular in shape. Said central portions determine that the tubular body has, in the section defined by said central portions of the walls, a prismatic region, that is to say a prismatic shape of constant cross section.

Alternatively or additionally each wall may additionally comprise a first intermediate portion adjacent to the first end portion and not coplanar with it, and / or a second intermediate portion adjacent to the second end portion and not coplanar with it, wherein at least some of the first and / or second intermediate portions are flat and trapezoidal or trapezoidal in shape, with two opposite sides laterally connected to adjacent walls of the tubular body through flaps located in the edge areas, defining a transverse section of the container decreasing in approximation to the first and / or the second ends, providing the container with a tapered shape.

That is to say that according to this embodiment the container several successive trunk-pyramidal or similarly connected sections in continuity, each section with different inclination. Typically the truncated-pyramidal or similar geometry corresponding to the first and second end portions will have a steeper slope than the truncated-pyramidal section or of similar preceding geometry, corresponding to the first and / or the second intermediate portion, the reduction being section of the container more pronounced in the first and second end portion than in the first and / or second intermediate portion.

Therefore, depending on whether the central and intermediate sections are included or not, the container may have a general geometry comparable to:

● two trunk-pyramidal or similar sections joined by their bases,

● two trunk-pyramidal sections or similar with their bases joined to an interposed prism;

● two trunk-pyramidal or similar sections superimposed with the base joined to the base of two other trunk-pyramidal or similar superimposed sections;

● two trunk-pyramidal or similar sections superimposed with the base joined to a prism and two other trunk-pyramidal or similar sections superimposed with the base attached to the opposite side of the same prism.

Evidently that the container could incorporate additionally more interposed sections, generating more rounded geometries.

The proposed package is also contemplated to optionally include the following characteristics:

● an opening or weakened or removable area included in said at least one cover or one of the walls of the tubular body;

The package contains a sealed bag connected to a dispensing device configured to dispense quantities of a liquid or granular product contained in said sealed bag;

the opening or weakened or removable area in correspondence with the dispensing device to allow access to said dispensing device therethrough from the outside of the container.

Each lid may be a lid body, independent of the band of corrugated sheet material, adhered to the tubular body, for example by adhesives. Said lid body may include flaps intended to be partially overlapped around the tubular body, facilitating its adhesion.

Each lid may be formed by lid portions joined in continuity with the band of corrugated sheet material by folds, conveniently folded and / or adhered to the tubular body to provide a lid.

Said lid may be formed of a single unitary piece of corrugated sheet material, or may be formed by the combination of multiple corrugated sheet material parts conveniently joined to cover the first or the second end of the tubular body, for example a plurality of triangular portions , each joined in continuity with the first or second extreme edge, which combined form a flat lid, which can be joined together by flaps or adhere to a superposed flat panel.

According to a second aspect of the invention, this refers to a sheet of corrugated sheet material punched and split to obtain a polygonal container. The proposed plate includes, in a manner known per se:

● a succession of three or more laterally elongated and flat walls connected through edge areas including creases defining creases, all the walls being integrated in a band of corrugated sheet material capable of being rolled and partially adhered on itself forming one closed enclosure with a first end and a second end defined by a first end edge and a second end edge opposite the walls;

● at least one cover plate capable of being joined to the tubular body by sealing the first end and / or the second end.

The invention also proposes, in a manner not known in the state of the art, the following characteristics:

● each wall comprises a first end portion adjacent to the first end edge, and a second end portion adjacent to the second end edge, wherein

● at least some of the first end portions and at least some of the second end portions are flat and trapezoidal in shape, and are laterally separated from the other adjacent walls by a space corresponding to an edge area containing at least a flap capable of being bent and adhered causing the closure of the space by placing the first and second end portions in contact with the adjacent walls in said edge area, defining a cross section of the container decreasing in approximation to the first and second ends, susceptible to define a container of tapered shape once formed.

Optionally it is contemplated that the at least one flap located in at least one of the edge areas located between two adjacent walls corresponds to a flap joined in continuity with one of said two adjacent walls through a crease defining a crease, said fold being flap capable of being adhered to the intrados of the other of the two adjacent walls.

It is also contemplated that the at least one flap located in at least one of the edge areas located between two adjacent walls may correspond to two symmetrical flaps, each joined in continuity with one of the two adjacent walls through a crevice that defines a fold and joined together also in continuity through another crevice that also defines a fold, the two flaps being capable of being faced and adhered one with the other.

According to another embodiment, each wall comprises a central portion, comprised between the first and second end portions, said central portion being rectangular in shape, capable of defining a prismatic region of the container once formed.

The possibility is also envisaged that each wall comprises a first intermediate portion adjacent to the first end portion and / or a second intermediate portion adjacent to the second end portion, wherein at least some of the first and / or the second intermediate portions they are flat and of trapezoidal or trapezoidal shape and are laterally separated from the other adjacent walls by a space corresponding to an edge area containing at least one flap capable of being bent and adhered causing the closure of the space by putting the first and seconds intermediate portions with the adjacent walls in said edge area, defining a cross section of the decreasing container in approximation to the first and second ends, capable of defining a container of tapered shape once formed.

It is also provided that the at least one cover plate is one or several cover plates joined in continuity with the first end edge and / or with the second end edge through a split defining a fold, thereby obtaining the cover of the band of corrugated sheet material that also forms the tubular body.

In order to obtain a general appearance similar to a barrel or barrel, it is also proposed that the tubular body and optionally also the covers, may be printed with an image or photograph of wood, preferably of natural wood staves.

Other characteristics of the invention will appear in the following detailed description of an exemplary embodiment.

Detailed description of an embodiment

The attached figures show examples of embodiment with non-limiting illustrative character of the present invention.

The proposed package consists of a tubular body 20, formed by a succession of laterally adjacent elongate walls 10 connected through edge zones 22, defining a hollow tubular body 20 with a first end 1 and a second end 2 open.

One or both of said first and second ends 1 and 2 will be closed by a cover 30, forming a container.

The tubular body 20 is obtained from a flat sheet of corrugated sheet material, such as cardboard, trimmed and provided with slots provided to facilitate its folding for the formation of the tubular body 20 or even the cover 30 or cover parts 31, as shown in Fig. 1c, 2c, 3c, 4c and 5b.

Each of the walls 10 that define the contour of the tubular body 20 consists of a first end edge 1a and a second end edge 2a opposite, as well as two lateral sides which are those that are connected to the adjacent walls 20 through the edge areas 22.

Each wall 10 includes at least a first end portion 11 adjacent the first end edge 1a, and a second end portion 12 adjacent the second end edge 2a.

It is proposed that the first end portions 11 of several or preferably all the walls 10 have a trapezoidal (i.e., regular trapezoidal) or trapezoidal (i.e., irregular trapezoidal) shape. It is also proposed that the second end portions 12 of several or preferably all the walls 10 have a trapezoidal or trapezoidal shape, causing a narrowing of the container, reducing the size of the first opening and therefore also of the lid.

In all the embodiments shown, all the first end portions 11 and all the second end portions 12 are trapezoidal, but as discussed it is contemplated that they may be trapezoidal producing irregularly shaped containers, or reciprocating for example first rectangular end portions 11 with first trapezoidal or trapezoidal end portions 11, or the same in the second end portions 12.

It is also indicated that, although all the examples shown correspond to tubular bodies 20 provided with eight walls 10, the invention covers packages having a number of walls 10 different, equal to or greater than three, which have not been shown to be obvious.

According to a first embodiment corresponding to the simplest embodiment, shown in Fig. 1a, the walls 10 of the container will only consist of a first end portion 11 and a second end portion 12 trapeciales joined laterally by the edge areas 22, defining in set a tubular body 20 in the shape of two truncated pyramids joined by their bases. This tubular body 20 is formed by eight walls 10 each provided with a first trapezoidal end portion 11 and a second trapezoidal end portion 12.

In this embodiment, and other equivalents, each first and second end portion 11, 12 trapezoidal are connected by sharing an edge, parallel to the first and second end edges 1a, 2a.

Figs. 2a and 3a show another embodiment in which the tubular body shows three overlapping areas with different general geometry. Said three zones correspond to a central prismatic zone of octagonal section comprised between two trunk-pyramidal zones of octagonal base located on the side and side of said prismatic zone whose bases are in contact with the octagonal faces of the prismatic zone, being one of the zones trunk-pyramids in inverted position. The assembly therefore determines a generally tapered or fusiform shape, with first and second ends 1 and 2 narrower than the rest of the tubular body 20. This tubular body 20 is formed by eight walls 10 each provided with a first portion trapezoidal end 11, a second trapezoidal end portion 12, and an interposed rectangular central portion 13.

In this embodiment, and other equivalents, each first and second trapezoidal end portion 11, 12 is connected and shares an edge with the rectangular central portion 13, said shared edges being parallel to the first and second end edges 1a, 2a.

Fig. 5a shows another embodiment similar to that shown in Fig. 2a and 3a, but in which the tubular body shows a total of five superimposed zones with different geometry, corresponding to an octagonal prismatic central zone that, on each side, has two zones of different trunk-pyramidal geometry of octagonal base superimposed. This tubular body 20 is formed by eight walls 10 each provided with a first trapezoidal end portion 11, a first trapezoidal intermediate portion 14, a second trapezoidal end portion 12, a second trapezoidal intermediate portion, and a central portion. 13 rectangular interposed between the first and second intermediate portions 14, 15.

In this embodiment, and other equivalents, each first and second trapezoidal end portion 11, 12 is connected and shares an edge with a first and second intermediate portion 14, 15, said shared edge being parallel to the first and second end edges 1a, 2a . Likewise, each first and second intermediate portion 14, 15 is connected and shares an edge with the central portion 13 rectangular, said shared edge being also parallel to the first and second end edges 1a, 2a.

Fig. 4a shows an embodiment similar to that shown in Fig. 5a. but in which the central portion 13 has been omitted, so that the general geometry corresponds to two superimposed octagonal pyramidal trunks joined at their base to two other inverted overlapping octagonal pyramid-trunk pyramids, each wall being defined by a first and a second end portion 11, 12 and a first and a second intermediate portions 14, 15.

Said tubular body 20 is obtained from a flat plate as shown in Fig. 1c, that is to say a band of flat rectangular corrugated sheet material provided with a plurality of transversal edge zones 22 between which the walls 10 are defined, with their respective first and second end portions 11 and 12.

The edge region 22 between two first or between two second end portions 11, 12 consists, in this embodiment, of three divergent slots which determine three folds 23 defining two flaps 24 and the lateral sides of two first or two second end portions 11. , 12 adjacent.

In the embodiment shown in Fig. 1c the first two or two second end portions 11, 12 adjacent have a vertex in contact, in which converge the three creases that determine the folds 23 of the edge area 22, creating two flaps 24 triangular However, in the embodiment shown in Fig. 4c the first two or two Second end portions 11, 12 adjacent to each other are completely separated by edge region 22, so in this case the flaps 24 are trapezoidal in this area.

When folding the band of corrugated sheet material to form the container the flaps 24 are faced and adhered by their obverse, forming a fold that closes the space of the edge area 22 between the first two or two second end portions 11, 12 adjacent , putting their respective lateral sides in contact as shown in Fig. 1b, and generating that a part of the formed container has a waning section in approximation to the first and second ends 1 and 2.

In Figs. 2c, 3c and 5b there is shown an alternative embodiment of said edge areas 22, according to which the band of corrugated sheet material has, in said edge areas 22 contained between two first or two second end portions 11, 12, a split defining a divergent fold 23 and a cutout between which a flap 24 is defined which is laterally attached to only one of said first two or second end portions 11, 12, and is separated from the other by the cut and in which intrados the flap 24 is superimposed and adhered when formed in a container, as shown in Fig. 2b.

The tubular body is proposed to have a cover 30 in one of its first or second ends 1, 2, or having two covers 30 one in each of the first and second ends 1, 2.

The aforementioned lids 30 can be formed from lid parts 31 joined together forming a lid 30, said lid portions 31 being preferably made of corrugated sheet material.

According to one embodiment, the lid parts 31 are a plurality of triangles that, joined by their vertices, completely cover the first or second end 1, 2 of the tubular body 20. Each triangle may be connected in continuity with the rest of the band of sheet material forming the tubular body 20 through a fold 23 coincident with the first or second end edge 1a, 2a, as shown in Fig. 3c.

Optionally it is proposed to join said triangles with one another through flaps 24, or preferably by superimposing and adhering another lid part 31 on said triangles, such as for example an octagonal lid part 31 also made of corrugated sheet material, as shown in FIG. shows in Fig. 3a.

According to another alternative embodiment, the lid 30 may be a lid body provided with a skirt intended to at least partially surround the first or second end portion 11, 12, adhering to its extrados. Said lid body may be formed from a flat sheet of corrugated sheet material as shown in Fig. 4b, provided with a central zone of size and shape complementary to the first and / or second end 1, 2 of the body tubular 20 to be covered, surrounded by portions of skirt distributed radially around it. Said skirt portions will preferably be trapezoidal or trapezoidal to obtain a cover body with a shape complementary to the end of the tubular body 20, and between the skirt portions there will be defined flaps 24 intended to join the skirt portions together forming a skirt. continuous.

In a preferred embodiment the package obtained is intended to contain a hermetic bag 40, filled with a liquid or granular material, and connected to a dispensing device 41, typically a tap.

According to this embodiment, one of the walls 10 or one of the covers 30 will include an opening or a weakened or removable zone 42 that will allow a user to access the dispensing device 41 from the outside of the container.

It is customary to use a retractable dispensing device 41, which can remain stored within the container during transport and marketing and which can be removed from the package through said opening or a weakened or removable zone 42 for dispensing quantities of the liquid or material granular stored in the hermetic bag.

It will be understood that the different parts constituting the invention described in one embodiment can be freely combined with the parts described in other different embodiments although said combination has not been explicitly described, provided that there is no harm in the combination.
