Definitions

  • the present invention relates to the field of packaging, in particular tubular packaging made of composite materials, and relates to a method of manufacturing and simultaneously placing a bottom or a cover on the body of a tubular packaging made of composite materials.
  • connection of these different layers is ensured by sealing or gluing.
  • the bottoms and the covers are produced separately from the bodies of the packages, either in a crimped metal part, or in synthetic material, or in the form of a membrane ensuring the sealing, for example, of aluminum, d '' a thickness between 50 ⁇ and 70 ⁇ . Then, once completed, they are attached to the body of the package and they are possibly surmounted by a cap or protective cap made of synthetic material.
  • Document US-A-2 438 430 also discloses a method of manufacturing and simultaneously placing a base or a cover on the body of a tubular packaging made of composite materials.
  • the establishment of the bottom or the cover is carried out using a disc with a diameter greater than the internal diameter of the body as well as a membrane whose material is identical to that of the inner layer of the body, namely paper.
  • this process does not make it possible to obtain a good seal.
  • bonding it is intended that the ends of the body become impregnated with adhesive, since the latter must infiltrate therein by capillary action in order to moisten it.
  • the internal paper layer allows this infiltration. Therefore, this bonding process does not guarantee the tightness of the box body.
  • the present invention aims to overcome these drawbacks, and proposes to provide a package whose bottom and cover are of a cost price proportionally equivalent to that of the body of the package, while ensuring rigidity and resistance identical, whatever the format and the section of the packaging, perfect liquid and gas tightness, total inviolability, and while still improving the external presentation of said packaging.
  • the subject of the invention is, in fact, a method of manufacturing and placing simultaneously a bottom or a cover on the body of a tubular packaging made of composite materials comprising a sealed internal complex, compatible with the product to be packaged, one or more layers of a material more rigid than the internal complex and, optionally, an external layer or complex, printed or not, consisting of applying to the body, in the immediate vicinity of one of its two ends, a complex, identical to that internal to the body of the package and in contact with the product to be packaged, the section of which is U-shaped and determines with the end of the body a cavity, (see US-A-2 438 430 for example), process characterized in that the complex is applied, in a completely sealed manner, by sealing, gluing or other, prior to placing on the complex, inside this cavity, several sheets, which are themselves maintained in place by gluing, the lower sheet being directly glued to the complex, then the following sheets being successively glued to each other, the sheets being made of a more rigid material than the complex and the number of sheets to
  • the sheets 8 are held in place by bonding, the bottom sheet 8A being directly bonded to the complex 7 and any subsequent sheets 8B ... and 8Z being bonded to each other, the sheets 8 may be made of corrugated paper, in cardboard, wood, metal, synthetic material, expanded polystyrene or any other material.
  • the complex 7 is folded over the external surface of the tubular end 1 ′ of the body 1 of the packaging, just before its application by sealing, gluing or the like (FIGS. 1B and 2B).
  • the tubular end 1 ′ of the body 1 of the package provided with the complex 7 is flared, so as to reinforce the total rigidity of the package (FIG. 3E).
  • a layer or a complex external 9 which can be identical to that 4 external to the body 1 of the packaging on the upper sheet 8A, ... or 8Z and possibly on the edge of the tubular end 1 ′ covered or not with the complex 7 (FIG. 3F) .
  • the tubular end 1 ′ of the body 1 of the packaging is wrapped around the complex 7 and possibly of the upper sheet 8A, ... or 8Z, in the shape of a U, so as to reinforce the total rigidity of the packaging ( Figures 4F and 5E).
  • the method of manufacturing and placing a bottom or a cover on the body 1 of a package therefore no longer consists, as in the prior art, on the one hand, of producing the bottom or the cover, then, on the other hand, to attach it and fix it to the body 1 by sealing, gluing, stapling or the like, but to manufacture the base or the cover simultaneously with its positioning on the body 1.
  • sheets 8 will be glued. Before the arrangement of the sheet 8A on the complex 7, either the contact surface of the complex 7 with the sheet 8 is coated, or the contact surface of the sheet 8 with the complex 7, or the two surfaces, partially or totally d 'a layer of glue 14. Then, if additional sheets 8B ... and 8Z are to be applied, either the contact surface of the first sheet 8A is coated, in place, with the second 8B, or the contact surface of the second sheet 8B with the first 8A, or the two surfaces, partially or totally with a layer of adhesive 14, and so on up to the sheet 8Z.
  • the adhesive used may for example be polyvinyl acetate.
  • the type of material to be used for the sheets 8 depends, of course, on the product to be packaged. Wood allows excellent insulation to temperature variations, metal allows heat transfer, etc. If 8 sheets of cardboard are used, the grammage will normally be greater than 225 g / m2. The thickness of each sheet 8 will vary depending on the weight and quantity of the product to be packaged. It can vary between 0.3 mm and 1 mm.
  • the upper sheet 8A ... or 8Z can be rectilinear like the other sheets 8 ( Figures 1D, 3D and 4D), or U-shaped ( Figures 2D and 5D), like the complex 7, in order to further increase the stiffness of the cover or bottom.
  • the complex 7 is provided with a weakening 11 of one of its layers, so as to facilitate the tearing off of the cover of the body 1 of the packaging, a tongue of tear-off 10 possibly being glued or welded to the upper sheet 8A, ... or 8Z before or after placement of the latter, a slight clearance 13 being provided between the sheets 8 and the internal surface of the body 1 ( Figures 6 and 7).
  • the weakening 11 makes it possible to facilitate full opening of the cover.
  • the tongue 10 being arranged on the upper sheet 8A, ... or 8Z, it is, of course, essential that, according to this embodiment, the sheets 8 are glued to each other, the sheet 8A being glued also on the complex 7.
  • the embrittlement It will advantageously be located on the vertical edge 7 'of the complex 7 and over its entire circumference.
  • the clearance 13 provided between all of the sheets 8 and the internal surface of the body 1 allows better removal of the cover.
  • the sheets 8A, ... and 8Z are each provided with an opening 12 and are arranged so that these openings 12 are superimposed, thus allowing direct access to the complex 7 of so as to be able to pierce it, a tear-off tab 10 possibly being glued or welded to the complex 7 before or after installation of the latter (FIGS. 8 and 9).
  • a tear-off tab 10 possibly being glued or welded to the complex 7 before or after installation of the latter (FIGS. 8 and 9).
  • the packaging obtained by application of the process consists of a body 1 of tubular shape comprising a sealed internal complex 2, compatible with the product to be packaged, one or more layers 3 of a more rigid material than the complex 2 and, optionally, a layer or an external complex 4 printed or not, the packaging comprising a bottom and / or a cover formed, from the inside of the packaging to the outside, by a complex 7 identical to that internal to the body 1 and in contact with the product to be packaged, using one or more sheets 8 of a more rigid material than the complex 7, such as corrugated paper, cardboard, wood, metal, a synthetic material, expanded polystyrene or any other material, the number of sheets 8 to be applied being a function of the rigidity of the bottom or of the cover of the packaging to be obtained, and optionally by a layer or an external complex 9 printed or not.
  • the complex 7 is folded over the tubular end 1 ′ of the body 1 of the packaging, the upper sheet 8A, ... or 8Z being either rectilinear (FIG. 1E) or in the shape of a U (FIG. 2D) so as to reinforce the rigidity of the bottom or cover of the package.
  • tubular end 1 ′ of the body 1 of the package is either flared (FIG. 3F), as well as the complex 7, or is wrapped around the complex 7 (FIG. 4F) and possibly the top sheet 8A , ... or 8Z in a U shape (figure 5E).
  • the means for the establishment of a bottom or a cover on the body 1 of a tubular packaging of composite material consist of a device 16 for the establishment of the bottom of the packaging and an identical device 16 for fitting the packaging lid, the filling of the packaging with the product to be packaged being carried out at a work station located between these two devices 16, each device 16 being either of the carousel type (FIGS. 10 and 11), or of the line station type (FIGS. 12 and 13), with a vertical or horizontal axis, the body 1 of the packaging can also be arranged vertically or horizontally.
