FR2898346A1 - Bag-in-box package, has main lateral panels connected to complementary panel by bend lines, where bend lines are pressed in inverse direction with respect to curved lines dividing main lateral panels - Google Patents

Abstract

The package has main lateral panels connected to a complementary panel e.g. connecting tab, by bend lines (6). The main lateral panels are extended from same side of the package through closure flaps connected to the respective main lateral panels. The panels are extended from an opposite side through other closure flaps connected to the respective main lateral panels. Curved lines (7, 8) divide each main lateral panel into three parts. The bend lines are pressed in an inverse direction with respect to the curved lines.

Description

The invention relates to a truncated pyramid-shaped package whose

  Lateral edges are pushed inside and have curvilinear double folds on the outside. The application shown is that of a "box-off", that is to say a package containing a flexible plasticized and waterproof complex in addition provided with a tap, and placed inside a semi package -rigid that gives it its outer shape, allows storage, transport, presentation and is the medium of information and decor. This semi-rigid package can be provided with a handle. The semi-rigid package is preferably made from a sheet material such as cardboard or corrugated cardboard. In the configuration shown and in the filling position, the package has a so-called "semi-automatic" bottom with entangled flaps and a top with so-called "overlapping" flaps. In the configuration shown and in position of transport or presentation at the point of sale, the package is returned to rest on its larger base.

  On the one hand, there are many "box-off" or other type of packaging whose appearance and parallelepiped volume at the point of sale are unattractive to the consumer. There are also packages of hexagonal or octagonal section which are a little more attractive without having curved edges. On the other hand, there are many packaging whose shapes are partially delimited by curves and which are therefore more original and more attractive but whose volume or filling can not be industrially productive, which is a constraint mainly in the field of "boxes-off" whose processes of implementation, filling and closure must remain simple and relatively fast at a time. There is no generally truncated pyramid-shaped package with curvilinear edges that allows for a compromise between an attractive presentation by the shape and a simple implementation on a line or a packaging station. 'packaging. The packaging object of the invention makes it possible to provide a concrete solution to these a priori contradictory requirements and also meet other usual and unavoidable requirements such as volume maintenance, stacking resistance or any other technical or functional requirement imposed transport packaging and presentation for sale.

  Figure 1 is a perspective view of the package in volume after shaping filling and closing. Figure 2 is a perspective view of the package during its shaping by the packager-packager user before filling and closing. Figure 3 is a plan view of the package, prior to folding and gluing at the manufacturer of the package. Figure 4 is a variant, also seen flat of the package, before folding and gluing at the manufacturer of the package, where the incoming folds are partially redoubled.

  The package is composed of a succession of main faces or side panels (1, 2, 3, 4) and a small complementary panel (5) articulated and interconnected by straight folding lines (6). , the small side panels (1, 3) alternate with the large side panels (2, 4) and form, as soon as they are manufactured, an enclosed lateral perimeter, the first small side panel (1) being extended by the small side panel (5). ) which is superimposed and stick inside the last large side panel (4). This small complementary side panel (5) is, in fact, a connecting tab. Each of the main side panels is then subdivided into at least three parts by curved fold and hinge lines. The curved lines (7 and 8) subdivide each of the side panels into three parts. The first panel (1) is subdivided into three parts (1 'and two 1 "), the second panel (2) into three parts (2' and two 2"), the third panel (3) into three parts (3). 'and two 3 ") and the fourth panel also in three parts (4' and two 4").

  Complementary folds (9), preferably also curved, again subdivide some panels (1 ", 3") or all panels (1 ", 2", 3 ", 4") optionally. In the case of an application to a box further, a cutout (10) articulated and unshelled allows to later extract the valve from the further serving as access door. Its position depends on that of the besides. The representation at the bottom and side of one of the large side panels is not exhaustive, it can also be located in the center of a large as a small panel. Each of the main side panels (1, 2, 3, 4) is extended on the same side of the package by a closure panel or flap respectively (11, 12, 13, 14) connected and articulated to the main side panel by a line bending respectively (21, 22, 23, 24). Each of the main side panels (1, 2, 3, 4) is also extended on the opposite side by a closure panel respectively (15, 16, 17, 18) connected and articulated to the main side panel by a fold line respectively (25). , 26, 27, 28). The lines of articulation of the flaps on the same side (21, 22, 23, 24) are substantially parallel to the lines of articulation of the flaps on the other side (25, 26, 27, 28) and substantially perpendicular to the lines articulation between the side panels (6). One of the flaps, here the flap (16), can be extended by a locking tab (19) which is positioned in a recess (29) arranged between the panels (4 and 18) interrupting and thus dividing into two parts the line folding (28). The tab (19) is then connected to the flap (16) and articulated with it by a fold line (30). Pick-up recesses (31) may also be optionally provided in certain flaps opposed to the mounting, here the flaps (15 and 17).

  Recesses (32) may be cut in the flaps for the passage of a handle.

  Once the packaging thus defined, cut and folded-on itself by the packaging manufacturer, it is delivered flat to the user packager-packer. The latter sets it in volume in the following way which makes it possible to explain in particular the functionalities assumed by each of the folding lines. At the beginning of the setting volume (fig.2), the four faces or main panels, then planes, form a tube of rectangular section, and are each extended in the same plane by future respective closing flaps which are adjacent thereto. For example, one side of this rectangular tube is the plane that includes the panel (1) and its respective extensions on either side (11 and 15). Then, the substantially straight fold lines (6) which delimit the main side panels (1, 2, 3, 4) are pushed towards the inside of the package already partially in volume while the curved lines (7 and 8) protrude outwardly thus forcing the split side panels to curve, the most important parts of these panels (1 ', 2', 3 'and 4') becoming convex, while the parts (1 ", 2 ", 3", 4 ") smaller and on both sides of the re-entrant edges (6) there is a tendency to get closer two by two inside the package. To limit the risk of strong resistance in case of opposition of the re-entrant parts (1 ", 2", 3 ", 4") when they meet inside the package, the complementary pleats are created (9 ) that allow to divide and weaken the upper part of the reentrant faces so that they take their place more effortlessly inside the package. Therefore, the exact positioning of these additional plies (9) can not be fixed, it depends on the thickness and rigidity of the material used and the proportions of the package in length, width and height. Sometimes these fold lines (9) can be reduced to short lines, ropes arches formed by the upper cuts (33) which delimit one end of the parts (1 ", 2", 3 ", 4"). Sometimes these lines start from half or less of the lines (6) to end at the ends on either side of the fold lines of the flaps (25, 27) for example as shown in Figure 3.

  In the variant shown in FIG. 4, the continuous fold line (6) is divided into a double fold line (6 ') whose ends meet by a rounded shape and are extended on either side by lines of single fold (6 ") of the same nature as the fold line (6) previously described In this variant also, the complementary fold lines (9) start from the central point of the broken lines (33) to project onto the lines Folding outwardly (7) .The user then closes one of the ends by bringing together and partially overlapping the flaps (15 and 17), and by hooking them, which makes it possible to maintain the volume of the generally trunk-shaped configuration. pyramid with curved faces and holding in position also the folded parts inside the package.

  The user then folds the flaps (18) and (16) that locks by introducing the tab (19) in the light (29). In this position, the flaps on one side (15, 17, 16 and 18) are substantially superimposed and sufficiently entangled to allow to proceed to the next phase of filling.

  The user then introduces the filled and closed in the packaging and then closes the latter by folding the flaps on the other side (11 and 13) then (14) and (12) which are then substantially superimposed in substantially parallel and in contact with each other and substantially parallel to the planes of the previous flaps (15 to 18). The package can then rest on its closed base (12) for storage and transport (fig.1) after having adhesive these flaps (11 to 14) between them. To obtain a satisfactory folding result, it is necessary to make so-called "inverted" folds for the hinge lines (6) folding inwards and folds in the usual direction for the others, particularly the curved lines (7 and 8). To also obtain an optimal folding quality, creasing counterparts are also required on the face opposite to the stamped face during the creasing and cutting operation at the packaging manufacturer, mainly for the inner fold lines (6). ) for which the material should not burst when bent so as not to be too aggressive in the event of friction with the walls of the flexible stuff contained in the packaging. Multiple and parallel folds can substitute for the single folds shown for the fold lines (6, 7 and 9).

  According to configuration and dimensional distribution, the joining lug (5) is itself divided, if necessary, into two parts (5 'and 5 ") by a hinge fold (34) and an optional recess (35) in order to present similar criteria of folding to those of the face on which it is sticking without adding too much resistance to the main folding defined by one of the lines (8) of the face (4).
