FR2873098A1 - Flat package for packing e.g. tile, has upper part and lower part obtained from same central panel, where parts are connected by hinges and withdrawn for being progressively placed in plane perpendicular to upper part - Google Patents

Abstract

The package has an upper part (30) and a lower part obtained from a same central panel (2), and connected and articulated on both sides by parts (31.1, 31.2) obtained from main side panels (3, 4). The parts connected by hinges (5, 6) are withdrawn for being progressively placed in a plane perpendicular to the upper part. A cutting (20) is delimited by cutting lines (21.1, 21.2) and articulated with panels by folds (22.1, 22.2).

Description

2873098 1

  The invention relates to a package whose volume, filling and closure can be mechanized and whose filling is achieved by lateral introduction of the contents.

  This package is made from a sheet material such as cardboard or corrugated cardboard.

  This packaging, after volume filling and closure around the content, is a substantially parallelepipedic envelope present on all sides of the parallelepiped but some faces may partially reveal the content.

  The aim is to reduce the surface area of material necessary for the realization of the packaging while ensuring the essential functions of grouping or protection of the content. For this purpose, the top and the bottom of the package are from the same panel and thus use in common approximately an area equivalent to the horizontal section of the package instead of usually using twice the value of this surface.

  Packaging is known, the reduction of material by partial removal of panels from other panels is one of the characteristics but these packages are rarely mechanized effectively, or, if they are, have characteristics of fragility and / or sometimes incompatible with an industrial use.

  The object of the invention is to overcome these disadvantages with a package using a reduced material format while preserving the simplicity of design by a small number of panels articulated together, strength and rigidity by joints of consistent length and the faculty of being mechanized economically by a number of reduced mechanical movements and movements identical to those which are technically mastered and already implemented on a large majority of machines volume packaging and closures.

  FIG. 1 is a view from above, or from below indifferently, of the flat package as supplied by the manufacturer of the packer-packager 2873098 2 packaging before filling, filling and assembling by this latest.

  Figure 2 is a view of a package identical to that shown in Figure 1 but in perspective and with arrows representing the movement of the main panels as it will be initiated during the subsequent volume development. Figure 3 is a view of the same packaging after volume and possibly assembled by the user conditioning.

  The package (1) initially consists of three approximately rectangular main panels, a central panel (2) connected to two side panels (3) and (4), aligned and articulated with these side panels by the respective fold lines (5). ) and (6). Each of these three main panels (2, 3, 4) is extended, on the opposite side, by other panels intended to be flaps of the packaging connected in pairs to these main panels. Respectively there are flaps (7) and (8) connected to the central panel (2) by the respective folding and hinge lines (9) and (10) and then flaps (11) and (12) connected to one of the side panels (3) respectively by the hinges (13) and (14) and flaps (15) and (16) connected to the other side panel (4) by the respective folding and hinge lines (17) and (18).

  It will be noted that the flaps (11, 12, 15, 16) extending the side panels are not approximately rectangular but are approximately trapezoidal, their free edge near the central portion at an angle of approximately 45 degrees with the respective folds of joints. (13, 14, 17, 18). The value of this angle is not critical and may very well be much more closed or even open up to 90 degrees so that each flap finds a substantially rectangular configuration. The purpose of this bevel cut to assign a trapezoidal shape flaps (11, 12, 15, 16) extending the side panels (3 and 4) is double.

  Firstly, it is a question of preventing these flaps (11, 12, 15 and 16) from coming into contact with the central flaps (7 and 8) too rapidly during the setting up of the packaging volume.

  Secondly, it is necessary to create between the flaps (8) and (12, 16) and (7) and (11, 15) an easily decorticable waste when the packaging is cut from a sheet material which is initially a simple rectangle having, at least, the dimensions of the packaging to be cut.

  However, according to a variant not shown of the invention, these bevels could perfectly form an angle of about 45 degrees or another value with the fold (9) for the flap (7) and the fold (10) for the flap (8), then conferring on the flaps (7) and (8) a shape each of isosceles or other trapezium while the flaps (11, 12, 15 and 16) remain approximately rectangular.

  In the main panels (2, 3 and 4) is arranged a cutout (20) delimited by the broken section lines (21.1) and (21.2) and articulated by the fold (22.1) with the side panel (3) and by the fold (22.2) with the side panel (4). This hinged cutout (20) is itself subdivided into three parts (30, 31.1 and 31.2) corresponding to the respective panels (2, 3 and 4) from which they are derived and hinged together by means of the same hinge folds (5). and (6) the panels from which they are derived or by unrepresented folds approximately very close and parallel to these lines of fold and articulation (5) and (6). According to Figures 2 and 3, during the setting volume, the central portion (30) of the blank (20) is pushed or pulled in a parallel plane but different from that of the panel (2). The two parts (31.1 and 31.2) which are connected to it by the joints (5) and (6) are, then, themselves drawn to be placed gradually in a plane perpendicular to that of the part (30), causing themselves the lateral parts (3) and (4) to which they are also connected by the folds (22) in a plane parallel to the preceding and perpendicular to that of the panels (30 and 2).

  At the same time or after lateral filling of the packaging thus set in volume, the panels (7, 8) are folded simultaneously or successively in a plane perpendicular to both the panel (30) and the panels (3 and 4). ).

  The same procedure is followed with the panels (11, 15) and (12, 16) which are folded to come, at the end of the race, to be placed in a plane substantially perpendicular to both the panels (3) and (4) and to the panels (2 and 30).

  The order of folding of the panels depends on the functionalities to be satisfied and the products contained to be packaged. It is possible to progressively fold the panels (7 and 8) after the panels (11, 15 and 12, 16) or to make the inverse according to the dimensional adaptation needs to shape constraints of the content or those of the external dimensions of the packaging. The panels (7 and 8) are respectively secured to the panels (11, 15, and 12, 16) by a cohesive means which is usually a gluing of the panels together or wrapping by a film or a strip.

  Once the volume is completed, the package filled with its contents and closed around this content, there is a single portion (30) central and central with respect to the face and a lower portion (40) divided into two remote parts from the center of the face and in direct relation with the side walls (7 and 8). It is obvious, even if it is not represented by drawings, that the concept of above and below is relative and that the parts (40) could constitute the top while the part (30) would constitute the following bottom that the direction (SI) is operated in traction or thrust and inverted with respect to that shown in Figure 2, resulting then a simultaneous inversion for the arrows (S2) and (S3) at the beginning of the volume development phase of the packaging.

  In the same way without prejudice to the invention, the parts (30) and (40) could themselves be multiplied or subdivided into narrower bands to distribute differently the maintenance or support of the content.

  The main but not exclusive applications of the invention may be the packaging of primary products or packages capable of being mechanically packaged according to the so-called lateral boxing method. The contents may be tiles, bricks containing liquids, sachets, folding boxes or cases.
