Definitions

  • the invention relates to a device for enabling the opening and closure of packaging, in particular made from cardboard and, more particularly intended for packaging in the form of bricks.
  • Cardboard-based packaging for liquid products has widely developed in recent years and are particularly suited to the conservation and storage of food products, such as in particular milk, fruit juice, etc ...
  • This type of packaging advantageously in the form of bricks, is particularly sought after, when the problems of transport, storage and, as a corollary, stacking.
  • the actual opening device consists of two parts fundamental, namely a peripheral ring attached to the packaging around the orifice, and intended to promote the flow of the liquid contained in the packaging, and a cover, articulated at one end of said ring, intended to cooperate with this in a sealed manner, to allow openings and closings successive, and which is secured to the end of the sealing film, so that when the packaging is used for the first time, that is to say when it is first used opening, the opening of the cover induces a traction on the sealing film, the descending from the periphery of the orifice and therefore allowing the opening proper of the packaging. Furthermore, given the dimensions of this opening system and closing, stacking of packaging remains possible.
  • the first opening of the package is to press this pusher element, once the lid is opened, so as to open the packaging proper, the following openings and closings being simply obtained by opening and closing of the cover, the pusher element then remaining permanently at inside the package.
  • this opening and closing device also allows, because of its small footprint, storage and stacking of the corresponding packaging, in however, during the first opening, the user gets their finger wet when exerts pressure on the pusher element.
  • this system is not hygienic.
  • a opening and closing system always for cardboard packaging in particular in the form of bricks, comprising a lever articulated at one of the ends of the ring.
  • This lever consists of two parts, namely a part internal, intended to pivot inside the packaging, and an external part, intended to allow the pivoting of the internal part, precisely by lever action by relative to the axis of articulation thereof.
  • Said lever is actuated by means of the cover during first use, so as to induce rupture of the areas of lower resistance or pre-cut to give access to the interior of packaging.
  • the cover intended to enable the successive openings and closings of the packaging, is in the open position before first use.
  • the flow of the liquid is relatively irregular and spattered, given the introduction air inside the packaging, occupying the volume released by the liquid.
  • the object of the invention is to overcome these various drawbacks. She offers an opening and closing device for packaging, in particular based of cardboard, and more particularly packaging in the form of bricks, simple to put in implementation, of a reduced cost price, and of easy installation.
  • the invention consists in setting up at the level of the area opening a package, in particular of brick type, an opening system using a lever to break the pre-cut areas beforehand performed, so as to free up a flow area, without risk of projection or wetting the user's finger.
  • said first part is connected to the hinge axis at by means of a flexible tongue; the rear end of said part cooperates with the front face of said second part in order to constitute a lever.
  • the first part is provided with a median projection directed in direction of the opening area, said projection being relatively tapered, so to facilitate the breaking of the pre-cuts defining the flow zone.
  • this projection is replaced by a point extending the anterior end of said first part, in order to fill the same function.
  • the peripheral ring comprises at the level of the flow zone, lugs directed towards the inside of the ring, and intended to cooperate with the rear face of the first part, so, after perforation of the pre-cuts, to maintain this first part substantially perpendicular to the plane of the opening area, so as not to disrupt the flow of liquid.
  • said second part is further intended, after being folded down, to pierce a pre-cut orifice intended itself to serve as a vent, also provided at the opening area.
  • said second part is provided with a projection pierced by a through light, formed substantially orthogonally to the in the plane of said part, and is intended to pierce the pre-cut orifice to form vent.
  • said projection has in the vicinity of its end lower an annular bead or projection, intended to cooperate with the edges of the orifice thus produced, to ensure the maintenance of said second part according to a position such that it does not affect the openings and closings of the cover on the ring.
  • the invention also relates to packaging, in particular cardboard, provided with such opening and closing devices.
  • Figure 1 is a schematic representation seen from above of a first embodiment of the invention.
  • Figure 2 is a plan view of the pre-cut areas of the area opening according to the invention.
  • Figure 3 is a schematic perspective representation of the lever according to the first embodiment.
  • Figures 4 to 9 are schematic views representative of the mode of operation of the device according to the invention.
  • FIG. 10 is a schematic representation seen from above of the device according to a second embodiment of the invention, FIG. 11 of which is a view in longitudinal section.
  • FIG. 12 is a plan representation of the precut areas of the opening area according to this second embodiment.
  • Figure 13 is a schematic perspective representation of a shape similar embodiment of the lever according to the invention.
  • Figures 14 to 16 are schematic perspective representations of the mode of operation of the device according to the invention.
  • Figures 17 to 20 are schematic representations in section illustrating the operation of the device according to the invention.
  • FIG. 1 therefore represents a schematic view from above of the opening and closing device according to the invention.
  • This opening and closing device is intended to be installed on a cardboard-based packaging, possibly aseptic, well known in itself, in particular in the form of a brick, and intended to contain a liquid, such as for example milk, juice fruit, etc ...
  • This packaging has on its upper face an opening zone (1), at level of which the opening and closing device conforming to the invention.
  • This opening zone (1) is in fact made up of a flow zone (2), limited by pre-cuts (3), for example produced by laser technology.
  • the opening and closing device according to the invention comprises basically three elements:
  • the first element consists of a peripheral element or ring (5), secured, in particular by gluing, on the upper face of the packaging around the opening area (1).
  • the second element is constituted by a cover (6), articulated at the end of the ring (5), at a hinge pin (7), as can be seen on Figure 1.
  • the cover is capable of cooperating with the ring (5), to ensure a tight seal, at least vis-à-vis the liquid or product contained in the packaging.
  • the third element is constituted by a lever (8), articulated on the ring (5) at view of the opening area (1) by means of a hinge pin (9).
  • the first part (10), of substantially semi-circular, triangular or trapezoidal, is connected to the hinge pin (9) by means of a flexible tongue (17), may have two lateral ribs (12), the height of which rises from its end up to the level of its place of cooperation with said second part (11) (FIG. 13).
  • the end (13) of said ribs (12), in other words, the rear face of said first part is intended to cooperate with the front face (14) of the second part (11), during the opening phase of the flow zone.
  • the anterior end of the first part (10) has a point-shaped projection (15), advantageously from molding, and intended to come to bear on the pre-cuts (3).
  • this projection is in the form of a median projection directed towards the zone opening, said projection being relatively tapered, so as to facilitate breaking pre-cuts defining the flow area.
  • the primer opening generated by the middle projection (15) causes the almost integral opening of the opening area, thereby promoting the subsequent flow of the liquid.
  • this first part (10) does not disturb the flow of the liquid out packaging, we continue the action of the lever, constituted by the second part (11) until blocking said first part by the thus cut portions of the opening area, which come to rest at the ends (13) of the ribs (12) or of the rear face of said first part.
  • peripheral ring (5) with lugs (16) directed inwards (see Figures 1, 13), so that they cooperate with the ends (13) of the ribs (12) or the posterior face of the first part.
  • the second part (11) plays, as already said, the function of a lever arm, in cooperating with the first part (10), to lead to the opening of the zone flow (2).
  • the opening area (1) also includes another area (4) limited by pre-cuts, and circular in shape, in the example described (see Figure 12).
  • This zone (4) is intended to constitute a vent, after drilling by the device according to the invention.
  • said second part (11) has a projection (18) directed downwards, extending substantially perpendicularly to its main face, and intended to induce rupture of the zone (4), so as to constitute a vent.
  • the projection (18) is pierced over its entire height with a light, thus forming a chimney, to allow communication between the exterior and the inside of the package.
  • the lower end (19) of the projection (18) is slightly tapered, in order to favor the rupture of the zone (4).
  • this end is extended by a much wider area (20), constituting a bead or annular projection, intended to cooperate with the area thus opened, so as to oppose the flap of the second part in anterior direction, and this, not to disturb the opening and closing of the cover (6) on the ring (5).
  • the assembly constituted by the ring (5) and the lever (8), comprising the two parts (10) and (11) comes from molding, and therefore constitutes a monobloc piece.
  • This opening and closing device therefore proves very particularly advantageous, in the context of preserving asepsis of the contents of the package for which it is intended. Furthermore, by its simplicity of implementation, and the realization of the parts which constitute it, in particular in molded plastic, it is of reduced cost. Finally, due to its one-piece nature, we optimize the rates installation, and therefore the cost price of the final packaging.
