Definitions

  • the present invention relates to a composite packaging in substantially polyhedral form, the content of which is made visible at least partially through its walls.
  • Soft plastic bags with or without handles, are inexpensive, light, quick to manufacture and space-saving after use. But these plastic bags are flexible and do not effectively protect their contents vis-à-vis external forces for lack of sufficient mechanical strength. They are often subject to untimely tears and form a medium-quality print medium.
  • the cardboard boxes are more solid and allow more effective protection of conditioned exchange.
  • the cardboard is a support allowing a printing of very good quality.
  • the cardboard boxes can thus include, on their external faces, information concerning the product, drawings, advertising messages, etc., and on their internal faces, printed games making it possible to cut the cardboard after use or other communications. But cartons are heavier and more expensive than flexible plastic bags, which are more complex to manufacture and bulky.
  • the flexible plastic bags can be at least partially transparent so as to allow the product to be seen.
  • the cardboard boxes are necessarily opaque and completely enclose the packaged product.
  • the object of the present invention is the production of an inexpensive composite packaging with a simple structure.
  • Another object of the invention is to produce a partially flexible composite packaging, which can be produced with all kinds of rigid and flexible materials.
  • the invention also relates to a partially flexible composite packaging, making the content at least partially visible and improving the presentation of the packaged products.
  • the packaging is preferably in substantially polyhedral form, for example substantially parallelepipedic, and constituted by at least two opposite lateral rigid walls and a rigid upper wall, integral with each other, and at least one wall flexible.
  • This composite packaging preferably includes a plastic film envelope preferably covering all the faces of the polyhedron, said plastic film forming the non-rigid walls of the polyhedron.
  • the flexible walls are advantageously at least partially transparent, thus making the contents of the packaging partially visible.
  • the plastic envelope is made from a transparent film.
  • the composite packaging is in substantially parallelepipedal form and formed by the combination of a flexible envelope of thin plastic material provided with a bottom opposite to an opening and of a stiffening template. consisting of three walls, made of cardboard or other materials, folded in a U shape.
  • the envelope is threaded so that its bottom is in contact with the middle wall of the U-shape, forming the upper wall of the packaging.
  • the opening of the envelope is closed, for example, by welding, after filling of the packaging.
  • the packaging includes a gripping means.
  • the middle wall of the U-shaped template can be provided with an elongated opening, parallel to the edges separating the walls of the U-shaped template.
  • the gripping means can be, for example, constituted by a flexible handle, accessible through the opening of the wall and the ends of which are fixed to the internal face of the central wall of the U-shaped jig.
  • the gripping means can also be constituted by openings or handles on the rigid and / or flexible walls, or on an integral part and outside thereof.
  • the U-shaped stiffening template is formed by folding a single piece of cardboard.
  • at least one of the free edges of rigid walls has a flap.
  • This flap is preferably folded on the internal face of the rigid wall corresponding to or perpendicular thereto.
  • the lower edges of the rigid side walls may not have a flap.
  • At least one of the ends of said flap in the folded position is blocked by a slot located on one of the adjacent rigid walls.
  • the thin plastic film forming the envelope of the packaging has precut patterns to facilitate, on the one hand, the grip grip through the opening of the upper wall and, on the other hand, the opening of the packaging on a flexible side wall, allowing the extraction of a product from inside the packaging.
  • the composite packaging of the present invention has many advantages.
  • the cost of manufacturing the packaging is significantly reduced compared to the cost of manufacturing a cardboard packaging of the same capacity, and has a mechanical resistance to crushing and to fixing roughly comparable to that of the cardboard packaging.
  • the combination of the U-shaped cardboard and the flexible transparent plastic envelope allows the packaging to have an appearance similar to a cardboard box, while making the contents visible through the flexible walls formed by the transparent envelope.
  • the packaging allows better protection of the product than conventional plastic bags. It also allows efficient storage without additional packaging, unlike plastic bags.
  • the cardboard walls of the packaging are better printing media than the plastic envelope. It is therefore possible to print only on the inner and outer walls of the carton, which eliminates the printing of the plastic envelope.
  • the packaging 1 is composite and consists of a stiffening template 2 in the shape of an inverted U and of an envelope 3 made of a transparent plastic film.
  • the package 1 is in the form of a parallelepiped having three rigid walls 2a, 2b and 2c constituted by the template 2 covered by the film 3 of transparent plastic material and three flexible walls formed by the transparent plastic film 3.
  • the upper face 4 of the packaging constituted by the plastic envelope 3 and the middle wall 2a of the template 2 in inverted U, is provided with a handle 5 in ribbon, as known by the name of Rinaldo or other, the ends of which are glued to the internal face of the middle wall 2a of the U-shaped jig.
  • An elongated opening 6 is made in the center of the middle wall 2a on the cardboard, to let the handle 5 pass from the inside towards outside of the package 1.
  • the plastic casing 3 has a first precut part 7 above the opening 6 of the template 2, so that the opening of the precut part 7 allows, first, to release the handle 5 from the inside the opening 6 of the template 2 and then, the grip of the handle 5 above the upper face 4 of the packaging.
  • the plastic envelope 3 is provided with a second precut part 8 located at the top of a flexible side wall 3a.
  • the opening of the pre-cut part 8 makes it possible to extract the product 9 contained in the packaging 1.
  • the template 2 is formed by folding a piece of cardboard.
  • the three folded walls, 2a, 2b, 2c, of the U-shaped template, are obtained according to the first fold lines 10.
  • Upper flaps 11a and side flaps 11b and 11c are provided respectively on the free edges of the walls 2a, 2b and 2c of the template 2.
  • the second fold lines 12, for the flaps are perpendicular to the first fold lines 10 of the walls.
  • the middle wall 2a of the template 2 has an elongated opening 6 placed in the center, parallel to the first fold lines 10.
  • the side flaps 11b, 11c are each provided with a tongue 13 at the end close to the middle wall 2a.
  • the wall 2a is provided, at each angle, with a slot 14 along a fold line 10, so that the side flaps 11b, 11c are folded on the internal face of the side walls 2b, 2c of the template and locked by the tabs 13 housed in the corresponding slots 14. Maintaining the folding can be improved by additional bonding of the side flaps 11b, 11c on the internal face of the side walls 2b, 2c.
  • the upper flaps 11a are also folded towards the internal face of the middle wall 2a of the template 2 and are held there, either by blocking the two ends by the side flaps 11b, 11c, or by gluing.
  • the handle 5 has its two ends glued to the internal face of the median wall 2a along the opening 6.
  • a cardboard template 2 is thus obtained, folded in the shape of an inverted U, the walls of which are reinforced by the upper flaps 11a and side 11b, 11c and the opening 6 of which on the middle wall 2a gives access to the handle 5 from outside the template 2.
  • the middle wall 2a of the template then constitutes the rigid part of the upper face 4 of the package and the side walls 2b, 2c the rigid parts of the rigid side faces of the package.
  • FIGS 4 and 5 illustrate two steps in the implementation of the packaging of the invention.
  • the product 9 to be packaged is housed in the template 2 of cardboard folded in inverted U shape.
  • the plastic envelope 3 in the form of a bag, provided with a bottom, is threaded from the top to the bottom on the template 2.
  • the bottom of the envelope plastic 3 is in contact with the upper face of the middle wall 2a of the template 2.
  • the lateral parts of the package 1 are also covered by the envelope 3 which thus forms two opposite flexible walls 3a, complementary to the two rigid lateral walls of the packaging 1 constituted by the side walls 2b, 2c of the template 2 covered by the plastic envelope 3.
  • the open end 15 of the plastic envelope 3 is at the bottom end of the package 1. It will be folded in the direction of the arrows towards the bottom of the package to be fixed, for example, by welding. The bottom of the packaging is then closed.
  • the flexible plastic envelope 3 has two parts 7 and 8 precut.
  • the precut part 7 corresponds to the opening 6 of the middle wall 2a of the U-shaped template and allows, as soon as it opens, to take the handle 5 located inside the opening 6.
  • the precut part 8 is located on a flexible side wall 3a and its opening allows access to the products 9 contained in the packaging.
  • the middle wall 2a of the template 2 is placed in the lower part of the packaging, thereby forming a non-inverted U.
  • the packaging 1 is filled with the products 9, then the open end of the envelope is closed on the bottom part of the packaging which then sits up.
  • the composite packaging thus obtained is turned 180 ° so that the middle wall 2a of the template, provided with the opening 6, is found at the top.
  • the cardboard template 2 it is preferable for the cardboard template 2 to serve as a communication medium and for the flexible plastic envelope 3 to be transparent. We can thus have a better presentation of the conditioned product 9.
  • the template 2 has more than three stiffening walls integral with each other. But at least one wall must remain flexible and preferably transparent. Furthermore, it is not essential to use a plastic envelope in the form of a bag to close the entire packaging 1 and, on the contrary, portions of flexible plastic films can be used to make the flexible walls. , the edges of the plastic films being made integral, for example by gluing, of the adjacent edges of the rigid walls.
