Definitions

• the present invention relates to a gripping device for parallelepiped packaging containing a liquid food to allow better grip of the package. More particularly, this is a container of relatively low capacity, for example 20 cl, intended inter alia for the packaging of fruit juice or milk in individual dose.
• the present invention aims to eliminate this disadvantage, by providing a container of flexible material of the kind considered, but which has a foldable gripping zone which is easy to use and safe for its handling and which is adapted to be grouped with other identical containers, while being able to be manufactured and filled in an industrial manner, at high rates.
• the folding cutting shape is modified so as to be able to affix tongues with rounded shapes (pellets or ears) or to directly stick these pellets on the food liquid packaging so that the two gripping zones Foldable can easily maintain the packaging without risk of overflow.
• Thermoplastic film-coated paperboard containers are commonly used for the packaging of milk, fruit juices, mineral water, these packages being generally produced from a continuous sheet of paper.
• thin material or cut blank
• paper whose inner face is covered with a metal film and the outer face of a thermoplastic film such as polyethylene.
• This packaging is shaped into a tube, closed by thermo-welding, then put in parallelepipedal form.
• the invention being characterized by two foldable gripping zones integrated in the form of cutting the fold and by the heat-sealing of two pellets on these said zones or according to a variant of the invention only by gluing the two pellets on the original packaging.
• Another simpler but less reliable solution would be to directly stick the pellets (ears) on the package without modifying its cut blank. That is to say: keep the packaging model for liquid food marketed today and so take advantage of the upper part of the container, with its two triangular flaps located on either side of the upper zone of the packaging to stick the two pellets.
• the two gripping areas fall back on the blanks of the brick so as to optimize its size (in the same way that it is marketed today) and thus facilitate its conditioning which can be grouped by 4, 6, 8 or 10 identical containers.
• the invention will be better understood on reading the detailed description which follows and on examining the appended drawings which represent, by way of non-limiting example, an embodiment of the invention.
• Figure 1 is a plan view of the blank cut with the pasting areas for pellets embedded in the blank.
• Figure 2 is a perspective view illustrating the general principle of the method with its unfolded gripping areas.
• FIGS 3, 4 and 5 are partial perspective views of the package which illustrate the various phases of closure of the gripping areas.
• Figure 6 illustrates a variant of the invention, which consists in sticking the pellets directly on the triangular angle flaps of a conventional brick liquid food after folding of the latter.
• Figure 7 is a perspective view of the invention integrally folded and ready to be packaged in a group.
• the packaging does not necessarily come from a tube divided by transverse welds.
• Fig. 1 is a blank for parallelepiped packaging made in a flexible material sheet or film.
• the blank according to the invention is obtained in one piece by appropriate cutting and creasing; conventionally, the fold lines that comprises creasing such a blank, are in the figure shown schematically by broken lines when they correspond to a first direction of folding, and by dashes, when they correspond to a second direction of folding, opposite to the previous, the cutting lines of this blank being, in turn, represented in solid lines.
• the gray areas these are the soldering zones of the packaging.
• the invention being characterized by the cutting shape of the blank (or tube). Indeed, as seen in FIG. 1, the rectangular shaped blank comprises projecting zones (a) and (b) disposed at an edge of the blank capable of forming the upper end.
• it is four semicircles which will serve as a support for gluing the pellets (c).
• the zones (a) and (b) are arranged in the extension of the fold lines (9) and extend on either side of the said fold line (9).
• the two semicircles (a) and (b) meet at a point of intersection (10) disposed at the intersection of the fold lines forming the substantially triangular angle flaps (5) and (5 ') .
• Fig. 2 represents a package obtained from a square section tube subjected to successive transverse welding operations (4) and a longitudinal weld (1), of a final cut shape and then shaped into parallelepiped-shaped packaging .
• substantially triangular angle flaps (5) and (5 ') are formed from the excess material which, for geometrical reasons, can not be shaped as a parallelepiped. There are therefore two pairs of flaps of substantially triangular angles, with the top (5) and (5 ') and bottom (not shown in Figures 2, 3, 4, 5, 6 and 7) overlying.
• the lower triangular corner flaps formed at the time of inward shaping are then folded onto the underside of the box to which they are attached. This shaping technique is well known ...
• the welding edge (4) formed after shaping the box extends the flap (5) and 100 (5 ') and the upper flaps (3) and (3') along a median plane perpendicular to the ridge (6). In this step (FIG. 3) the zones (a) and (b) are opposite one another.
• the zone (b) is folded in a folding-folding manner (7) so that the zone (b) comes into contact with the upper flap (3) and the flap (5).
• the pellet (c) can then be glued to the zones (a) and (b).
• pellets (c) are fixed by a single sticky pressure operation during the final phase of the package.
• the pellet (c) and its hidden areas are folded partly by the drawing [bonding zone (a) and (b) as well as its angle flap (5), (5). ')] around the edge (6) so that said flap (5), (5') can be attached to the side wall 115 (2 ') by easily tearable welding means.
• FIG 6 it is possible to preserve the cutting form customarily used for shaping packaging for liquid food and to be content with fixing the pellets (c) on the welding edge (4). during the final phase of the packaging so as not to change the original characteristics.
• the packaging according to the invention has a certain advantage over known packages of this type, the maintenance of which is systematically subject to splashing due to the pressure of the fingers on the latter.
• the packaging container can be made in various other ways and covered with other coatings than those described.
