Description

FOLDING COVER FOR WRITING ITEMS Field of the Invention

The present invention concerns a folding beaker for writing articles, of the type constructed in sheet material and comprising an upper face with an opening, a face c. ^• wave and surrounding outer side walls, the upper and lower faces being linked to each other through a movable panel forming a foldable articulated quadrilateral, so that said beaker is capable of adopting a compact flat arrangement, suitable for storage and transport, in which all the panels, faces and walls are totally or partially superimposed in a substantially coplanar manner, and an armed arrangement, suitable for use, in which the upper and bottom faces are mutually parallel, said mobile panel acting as a internal reinforcement wall. Technical background

It is known in the prior art by the Utility Model ES-A-295474U a folding beaker of this type called "device advertising ^'" in said articulated quadrilateral is formed by an upper face hexagonal, a rectangular movable panel, a hexagonal bottom face and mutually engaging flaps at its ends to form a rectangle similar to that of the mobile panel, which are derived respectively from sides of the upper and bottom faces opposite the linking sides of the mobile panel. All these pieces form a development of a cardboard of a considerable thickness necessary to provide rigidity to the whole of the beaker, and are obtained from a thin sheet, generally printed in those areas that will be visible with the beaker armed, attached and glued on a thick sheet of support and subsequently stamped. The side walls are formed by a strip of six rectangular side panels, of equivalent width to the side of the hexagon, mutually linked by fold lines located on opposite sides, duly bent so that the panel located at one end of the strip is attached and glued to an extension of the other end panel. Said strip is obtained from a relatively thin sheet printed on the face that will be outside once assembled. The development of the pieces that form the aforementioned quadrilateral is duly folded so that the said flaps fit together forming the said rectangle, which is attached and glued on the inner face of one of the intermediate side panels, generally in a manual operation. It requires a certain precision. Subsequently, the operation of closing the strip of side panels by means of said gluing of the last on an extension of the first.

This known beaker, as is evident, is formed by three pieces or structures of materials of different thicknesses, assembled by manual operations of a certain precision, one of whose materials (thick cardboard), due to its considerable thickness, does not: Directly printed but should be printed on a thin material that is subsequently attached and glued on a thick support material, while the other material is printed directly in a separate operation. All this implies a considerable expense of time and money.

It is also known by the Utility Model ES-A-1027684 a folding advertising display that in assembled position forms two curled side walls, convex towards the outside, presenting an ogival cross section. This model is obtained from a single piece of printable sheet, stamped, folded and glued, which includes appendages that are located inside to help the side walls maintain the desired curled shape. However, the object obtained does not constitute a true beaker, that is, a receptacle with an open top face and with a bottom closing the entire inner perimeter suitable for containing objects (and therefore of sufficient strength), such as writing articles, It is only useful as a support for graphic information on the external faces of its side walls.

Utility Model ES-1044717 describes a cardboard bin with a hexagonal base prismatic shape, constituted from a single laminar body in which a cutting and folding lines are defined in a die cut operation that determine a development with a first base sector, hexagonal, from one of whose sides derives a second rectangular sector corresponding to the side walls divided by fold lines. Each free side of the base hexagon has an protruding flap and each side wall has a groove in its lower part. When the bin is armed, each of said fins is inserted into one of said corresponding grooves, and a fin extending the end of the final side wall into a groove located in the first edge of the side walls. This model is obtained from a single sheet and is assembled and disassembled. However, when such a bin is disarmed, it occupies the full extent of its development, and the assembly and disassembly operations are complicated and must be carried out completely by hand. On the other hand, in the armed situation, the bottom sector is distanced from the ground supported in an unsafe way only by the aforementioned fins inserted in the grooves of the side walls, whose fins protrude from outwardly of them in an inconvenient way. On the other hand, for the laminar element to be printable, it must be thin, which will give the armed assembly weakness.

Object of the invention Accordingly, the objective of the present invention is to provide a folding beaker for writing articles, constructed of sheet material, capable of adopting a compact flat arrangement, suitable for storage and transport, in which all the elements which constitute it are totally or partially superimposed in a substantially coplanar manner, and an armed arrangement, suitable for use, in which upper and bottom faces are mutually parallel, whose beaker is obtained from a single piece of printable sheet, of homogeneous thickness, capable of being punched, creased, folded and glued in a fully automatic process, in which all the useful surfaces as a support for graphic information, visible, both when it is in said compact flat arrangement and when it is in said armed arrangement, belong to the same face of said piece of printable sheet, and that you nga a configuration such that in said armed arrangement it has sufficient rigidity to maintain its forms in a stable manner, even when pressed with the fingers. Brief exposition of the invention

The above objective is achieved, in accordance with the present invention, by providing a beaker that is obtained from a single-piece development of a printable sheet material of uniform thickness. In said development there is a first upper face panel with a first opening, a movable panel, a bottom panel, a fixed panel and a second upper face panel with a second opening, all of them forming a first strip, in the order mentioned, and linked to each other by fold lines. From a side of said fixed panel, a plurality of side wall panels which in turn form a second strip in a direction perpendicular to the first are derived through a fold line, said side wall panels being linked to each other. by fold lines. Said development is capable of being folded so that said first and second upper face panels, which derive from opposite areas of the die cut development, are superimposed, attached by opposite faces of the printable sheet piece, with said first and second openings. coincident, and glued together forming said upper open face with a thickness appropriate to the required stiffness. Said strip of side panels is also conveniently folded, and the side wall panel located in the free end of said strip is attached on said fixed panel and glued on at least one area thereof. In this way, at least one side wall formed by a side wall panel superimposed on said fixed panel is of double thickness increasing the general stiffness. On the other hand, in the assembly arrangement the mobile panel is always superimposed, although not glued, internally to a side wall panel, which also contributes to an increase in rigidity. In the proposed embodiments, which are set out below, there are extensions of the mobile and / or fixed panels that make all the side walls, or a large area thereof, consist of a double layer. In addition, a special configuration of the bottom panel and / or the elements that link it to the fixed panel means that said bottom panel acquires, when the beaker is in the armed arrangement, a three-dimensional configuration that confers great rigidity to the whole. On the other hand, the beaker of the present invention is capable of adopting a compact folding arrangement in which all its panels are totally or partially superimposed substantially coplanar. The term "fixed panel" is used herein to designate a panel that, as part of said articulated quadrilateral, remains fixed when the beaker is supported by its side walls, either in the assembly or folding arrangement, or in the transitions between the two, while the term "mobile panel" is used to designate a panel belonging to said articulated quadrilateral that adopts different positions depending on whether the beaker is in the assembly or folding arrangement, and which describes a trajectory accompanying the proper positioning of the top and bottom faces in the transitions between both arrangements.

Detailed description of the preferred embodiments

Referring first to Fig. 1, there is shown a development 101, in one piece, die cut from a printable sheet of homogeneous thickness, typically a cardboard of a weight of 250 to 350 g / m ² . In said development 101, a first upper face panel with a first opening 5a is linked by a fold line 21 to a mobile panel 2 (during arming and disassembly operations), which is linked by a fold line 22 located on the opposite side, to a bottom face panel 3, which in turn is linked by a fold line 41, located on an opposite side, to a fixed panel 4 which is linked by a fold line 42 , located on the opposite side, to a second upper face panel Ib with an opening 5b, forming a strip. In this exemplary embodiment, the first and second upper face panels la, Ib, which as explained below will form an upper face 1 of the beaker, are identical and have a regular hexagon shape, and in turn the mobile panels and fixed 2.4 are also equal, rectangular in shape, with a width substantially equal to the side of said regular hexagon and of a predetermined height.

Folding this strip conveniently along the aforementioned fold lines 21, 22, 41, 42, which are mutually parallel, the second upper face panel 1 b exceeds the first upper face panel the, with the first and second openings 5a and 5b matching, attached and glued together by opposite faces of said printable sheet to form said upper face 1 of the beaker (Figs. 2 and 3). With this first phase of the assembly a quadrilateral is formed, articulated by the mentioned fold lines 21, 22, 41, 42, in which the upper face 1 is always kept parallel to the bottom face 3 and the mobile panel 2 is maintained always parallel to the fixed panel 4, whose quadrilateral can adopt an infinite number of positions, with a position in which the mobile and fixed panels 2, 4 form right angles with the top and bottom faces 1, 3, and at least one folded position , flattened and compact, in which all panels and faces adopt a totally or partially superposed and substantially coplanar position. It should be noted that the assembly folded in said "flat" arrangement is capable of being printed acting on a blank portion of one of the panels, in order to be able to further customize the beaker.

Returning to Fig. 1, the development 101 further comprises lateral extensions 2a, 2b of the mobile panel 2 linked thereto by respective fold lines 23, 24 and lateral extensions 4a, 4b of the fixed panel 4 linked thereto by respective fold lines 43, 44, the width of said lateral extensions 2a, 2b, 4a, 4b being substantially equal to that of the mobile and fixed panels 2, 4 and consequently to the length of the hexagon side. From one of said lateral extensions 4a of the fixed panel 4, six side wall panels 6 linked to each other by fold lines 61 are derived through a fold line 62, forming a side strip. Said side wall panels 6 are rectangular, of width substantially equal to the side of the hexagon and of a height equal to or greater than the height of the movable and fixed panels 2, 4, being arranged such that upper edges of the wall panels side 6 are parallel to said fold line 41 and slightly offset above it, while lower edges of the side wall panels 6 are substantially aligned with the fold line 42, thereby facilitating automatic folding (free movement of the sprats).

The side wall panels 6 are duly folded by the fold lines 61 surrounding said previously formed articulated quadrilateral so that the three side wall panels 6 located at the free end of the strip are superimposed on the fixed panel 4 and its lateral extensions 4a, 4b, at least the side wall panel 6 of the end of the strip being enclosed over at least one area of the lateral extension 4a.

This operation completes the assembly of said beaker, which is capable of adopting a compact flat layout (Fig. 2), suitable for storage and transport, in which all panels, faces and walls are totally or partially superimposed substantially coplanar, and an armed arrangement (Fig. 3), suitable for use, in which the top and bottom faces 1, 3 are pendulous to the side walls 6. In any arrangement, the upper face 1 has double thickness, as explained above which gives it great strength in a situation of assembly and the three side walls formed by the three side wall panels 6 overlapping and glued on the fixed panel 4 and its lateral extensions 4a, 4a also have double thickness, while the mobile panel 2 and its lateral extensions 2a, 2b constitute internal reinforcement walls for the remaining three side walls when the beaker is in the provision of armed.

In the exemplary embodiment shown in Fig. 1, said bottom face panel 3 comprises two fold lines 31 mutually parallel and respectively aligned with said fold lines 23, 43 and 24, 44 linking between said movable and fixed panels 2, 4 and their respective lateral extensions 2a, 2b and 4a, 4b, whose fold lines 31 define in said bottom face panel 3 a central rectangular area 3c and two lateral areas 3a, 3b triangular isosceles, with equal sides of length slightly greater than the length of the side of said regular hexagon of the upper face 1, so that when adopting said assembly arrangement the panel of the bottom face 3 acquires a three-dimensional configuration (see Fig. 4), with said zones sides 3a, 3b slightly bent upwards, which confers greater rigidity to the assembly. In the development 101 of Fig. 1 it is shown that each of said lateral areas 3a, 3b of the bottom panel 3 comprises an extension linked to said lateral extensions 4a, 4b of the fixed panel 4 by folding lines 34a, 34b aligned on both sides with the folding line 42 linking the fixed panel 4 with the bottom face panel 3 forming, together, a fold line 34a-42-34b. The purpose of this fold line 34a-42-34b is to ensure precise positioning of the first upper face panel 1 attached to the second upper face panel 1 b for gluing during an automated production phase. Each one of said extensions of the lateral zones 3a, 3b further comprises oblique fold lines 32, 33 which define triangular zones which, when the beaker adopts said assembly arrangement, form folds (see Fig. 4) which they provide the aforementioned three-dimensional configuration to the bottom face panel 3 which confers greater rigidity to the assembly.

It should be noted that the bottom edges of the side wall panels 6 are substantially aligned with the fold line 42 linking the base panel 3 with the fixed panel 4, such that said three-dimensional configuration of the bottom face 3 comprises, in said armed arrangement, as shown in Fig. 4, an area at a lower level that is flush with the lower edges of said side wall panels 6 and supported on a fixed plane supporting the beaker, while said mobile and fixed panels 2, 4 are smaller than the wall panels side 6, with upper edges of the side wall panels 6 being misaligned and displaced upwardly relative to the fold line 41 linking the fixed panel 4 with the second upper face panel Ib, so that, in said arrangement of armed, the upper face 1 is at a lower level with respect to said upper edges of the side wall panels 6.

The shaded areas of the development 101 represent all those zones thereof that are visible, both when it is in said compact flat arrangement (Fig. 2) and when it is in said armed arrangement (Fig. 3), which as evidently belong to the same face of said piece of printable sheet. These visible areas are suitable as a support for graphic information, for example, advertising, calendars, useful addresses, decorative motifs and the like, which are printable in a single printing operation prior to punching and assembly of development 101. As indicated previously it is possible to leave a blank area (eg panel 2a) without printing for further printing, on said area when the beaker adopts a flattened arrangement (Fig. 2, 6 and 10)

In addition, both die cutting and assembly operations, which include folding and gluing, can be performed automatically with conventional equipment from the graphic arts industry.

A variant of the beaker according to the present invention is shown in Fig. 5 to 7 which is in all similar to the beaker of Fig. 1 to 4 except in appendages added to the upper face 1. The description of the general constitution of the beaker of Fig. 5 to 7 has been omitted since it is identical to the description of the embodiment of Figs. 1 to 4 above, and equal numerical references have been used to designate equivalent elements. Only the differentiated parts are described below. Thus, the development 102 of Fig. 5 differs from the development 101 of Fig. 1 only because the second upper face panel Ib, which once assembled is the visible upper face panel, comprises linked fins 16. 17 through respective fold lines 18. 19 to two of its adjacent sides to its side linked to the fixed panel 4. For this, the upper edges of the lateral extensions 4a, 4b of the fixed panel 4 have cut-outs 49 which make possible the arrangement of material for said fins 16, 17. For its part, the first upper face panel the , which is the one that is inferiorly attached to the second upper face panel Ib, and therefore not visible, does not have a regular hexagon shape but has two sides adjacent to its side linked to the mobile panel 4 longer than opposite sides to them. These longer sides comprise fins 11, 12 linked thereto through respective fold lines 13, 14, which are secant to the regular hexagon of the second upper face panel Ib. Said fins 11, 12 have pointed ends 15. In the armed position, fins 1 1, 12, 16 and 17 are bent orthogonally and the pointed ends 15 of fins 1 1, 12 are supported on the inner face of the fins 16, 17, preventing its folding inwards and constituting a reinforcement in transverse direction of the upper face 1. When the beaker is in the armed arrangement the fins 1 1, 12, 16, 17 are not visible, so which looks identical to that of Fig. 3 and 4. Fig. 7 illustrates how to move from the folded arrangement of Fig. 6 to the arming arrangement by pressing down the movable panel 2 and its extensions 2a , 2b, whereby said articulated quadrilateral formed by the movable panel 2, the fixed panel 4, the upper face 1 and the bottom panel 3 begins to open and the side wall panels 6 begin to separate adopting said prismatic configuration, while the fins 1 1, 12. 16 and 17 associated with the upper face 1 unfolds until they are locked together when the beaker is fully armed. To proceed with its folding, a reverse operation is carried out, pressing inwards the bottom panel 3.

In Figs. 8 and 9 shows a development 103 of a beaker in accordance with the present invention that exhibits many similarities with the beaker of Figs. 1 to 4, except in the background zone configuration. The description of the general constitution of the beaker of Figs. 8 and 9 has been omitted since it is identical to the description of the embodiment example of Figs. 1 to 4 above, and equal numerical references have been used to designate equivalent elements. Therefore, only the differentiated parts are described below. Referring to Fig. 8, the development 103, said bottom face panel 3 comprises, as in the previous embodiment examples, two fold lines 31 defining a central rectangular area 3c and two lateral triangular areas 3a, 3b isosceles, each with two free sides 35, equal, of length slightly greater than the length of the side of said regular hexagon of the upper face 1. Thus, these triangular lateral areas 3a, 3b are not linked to the extensions 4a, 4b of the fixed panel 4 and in the armed arrangement alone take a bent position with respect to the central rectangular area 3c due to its greater length. This bent position is part of the aforementioned three-dimensional configuration that confers greater resistance to the base of the beaker.

On the other hand, the mobile and fixed panels 2, 4 are also smaller than the side wall panels 6, but in this case, the lower edges of the side wall panels 6 are also misaligned and displaced below the line fold 42 linking the fixed panel 4 with the base panel 3. This means that in the assembled position, shown in a lower perspective in Fig. 9, the base panel is retracted inward, spaced from a plane of beaker support. In order to provide a good lift and a good horizontal positioning of the base panel 3 and the upper face 1, the lateral extensions 2a, 2b of the movable panel 2 are provided with extensions 25 in the form of legs, dimensioned so that in the aforementioned Arming arrangement said extensions 25 abut the aforementioned fixed support plane, such as a table.

Referring now to Figs. 10 to 13, there is shown a beaker according to the present invention that has many similarities with the beakers of the embodiments described above, although the final shape is different, so that in its description numerical references have been used Same for equivalent items.

As in the previous examples, a development 104 comprises a first strip formed successively by a first upper face panel 1 a with a first opening 5a, a movable panel 2, a bottom panel 3, a fixed panel 4 and a second panel of upper face Ib with a second opening 5b, all of them linked to each other by fold lines 21, 22, 46, 41. However, here the first and second upper face panels la, Ib have an ogival shape and the mobile panels and fixed 2, 4 have a width approximately equivalent to the rectilinear development of the curved sides of said ogival shape. From a side of the fixed panel 4 a second strip formed, in this case, is derived by two side wall panels 6 of width equally similar to said rectilinear development.

Also in this example of Figs. 10 to 13 the beaker is capable of adopting a compact flat layout, suitable for storage and transport, in which all panels, faces and walls are totally or partially superposed in a substantially coplanar manner (Fig. 11), and an armed arrangement, suitable for use, in which the top and bottom faces 1, 3 are perpendicular to the side walls 6 and where the movable panel 2 constitutes a second internal reinforcement wall, with the particular feature that the assembly adopts in this case a form of an ogival cross-sectional tale (Fig. 12), with two curled side walls and an internally curvoconcave bottom ( Fig. 13) comprising an area at a lower level that is flush with lower edges of the side walls 6 and resting on a support surface of the beaker.

Said fold lines 21, 22 and 41 are of relatively short length to enable bonding and folding between panels that have curved lines without forcing the bending of said panels. On the other hand, the fold line 46 that links the bottom panel 3 with the fixed panel 4 is of a relatively large length and has such means that, when a fold is made by said fold line 46, both said bottom panel 3 as the fixed panel 4 are forced to adopt a certain curled configuration. For this, the fixed panel 4 comprises an extension 45 linked thereto through a fold line 42a, to whose extension said bottom panel 3 is linked by means of said fold line 46, which is formed by a combination of alternating cuts 46a and recesses 46b, of small length, each cut 46a of small length connected by its central area to a cut of greater length 47 extending through said extension 45 and into the fixed panel 4 parallel to the lateral edges thereof, crossing said fold line 42a in particular, so that when the beaker adopts said assembly arrangement, the side wall panels 6 acquire said curled configuration while the bottom face panel 3 acquires an internal configuration curvoconcave (see Fig. 13), three-dimensional, which confers greater rigidity to the whole.

Returning to said development 104 the bottom face panel 3 has a substantially ogival shape with two curved convex sides. one of which, facing the mobile panel 2, has cutouts 36 at the ends to facilitate the passage of extensions 25 of the mobile panel 2, which has one side facing the bottom face panel 3 with a curved convex central portion 26 between said extensions 25. On the other hand, both the fold line 62 of linking a side wall panel 6 with the fixed panel 4 and the fold line 61 of mutual connection of the two side wall panels 6 are formed by two parallel rectilinear grooves, close to each other to get the fold provide a slightly chamfered edge. In addition, the mobile and fixed panels 2, 4 comprise fold lines 28, 48 relatively close and parallel to both side edges thereof that facilitate a slight fold of said edges by lightening the pressure on the side walls in the assembly arrangement. Also in development 104 all those areas thereof that are visible, both when the beaker is in said compact flat arrangement (Fig. 1 1) and when it is in said armed arrangement (Fig. 12) they are on the same printable face of the starting sheet material. Also the operations of both die-cutting and assembly, which include folding and gluing, can be performed automatically with the conventional equipment of the graphic arts industry.

As evidenced above, in any of the three previous embodiments the beaker is obtained from a single piece of a printable sheet material, the material of which is typically a cardboard of a weight between 250 and 350 g / m ^" , satin on one side intended to receive all of the aforementioned graphic information in a single printing operation prior to punching, folding and gluing operations. However, other materials such as plastic foil, wax paper, laminated paper are possible or metallized, and the like.

It is also possible to construct beakers of polygonal cross-section in the form of an irregular hexagon or different from the hexagon, provided that said polygonal shape has two opposite sides, mutually parallel, respectively linked to said mobile and fixed panels 2, 4, flanked by both sides by the same even number of sides, and that said outer side faces, formed by the side wall panels 6, are in a number equal to the total number of sides of said polygonal shape and are of a width equal to a respective side of the aforementioned polygonal form. In an alternative embodiment of the invention, it is provided that the openings (5a, 5b) of the upper face panels be rectangular, in which case the beaker can also be used for desk items for display of leaflets arranged in a manner that enter through said oblong opening and protrude from the beaker from the top to be grasped.
