Definitions

  • the invention relates to a tight packaging packaging with easy opening for pasty products, in particular for food products such as processed cheese or semi-salt, composed of two thin sheets, namely a first sheet, cut according to an appropriate contour and shaped in shell by folding so as to reveal the bottom and the lateral faces of the packaging, and a second sheet forming a cover, cut to the dimensions of said bottom and laid flat on the surface of the product to be conditioned previously placed in said shell.
  • the parts of the first sheet forming said side faces are extended by flanges which are folded down and heat-sealed on the edges of the second sheet, the respectively inner faces of the first and outer sheet of the second sheet being coated for this purpose with a heat-sealable lacquer.
  • a portion of the first sheet, comprising the bottom and at least one lateral face constitutes a wide opening strip which must be torn along the fold lines bordering said lateral face and the bottom by traction on a tongue formed by the rim of this last lateral face, wider than the other rims.
  • the object of the invention is to remedy this drawback and to arrange the packaging considered so as to ensure perfect separation of the opening strip and complete "undressing" of the product contained in the packaging.
  • This object is achieved by providing, along the fold lines which laterally delimit the opening strip of the packaging, reinforcing strips adhering to the first sheet in which this strip is taken and guiding the progression of the tear during the opening of the packaging, these reinforcing strips, considered on the first sheet before folding thereof, being rectilinear and each of them extending on one side over at least part of the lateral face opposite to the pull tab and on the other side up to a part of the enlarged rim forming said tab, so that the reinforcing strips, which extend parallel or substantially prallement between them over most of their length, direct towards each other over the rest of their length - after folding the first sheet - by terminal portions belonging to the tongue and along the fold line located at the foot thereof.
  • the opening of the packaging is carried out along a double tearing path, starting from the center of the foot of the tongue, diverging towards the lateral edges of the face adjacent to the tongue, then along these lateral edges and then those of 'a second side (the bottom of the packaging) and a third side (opposite the first).
  • the opening is therefore complete and leaves no retention corner of the packaged product.
  • the width of the widened flange is such that between the two folded corners of the tongue remain exposed of the heat-sealable portions of the first sheet and of the second sheet. opposite.
  • the width of the widened flange is such that between the two folded corners of the tongue remain exposed of the heat-sealable portions of the first sheet and of the second sheet.
  • the enlarged rim is complementary enlarged in a central part of its border, over a length less than the width of the opening strip, so that the entire surface the pull tab is covered by the folded corners, with the sole exception of the above-mentioned thermosettable portions, these being delimited by a small window defined by the terminal notches appearing at the angles of said flange due to the presence of said central part enlarged.
  • the pull tab remains free over most of its surface, being welded to the second sheet only inside said window, located in the middle of its base, this welding sufficient sealing in this region of the package.
  • the reinforcing strips of a package according to the invention can advantageously be heat-sealed on the first sheet.
  • fracture initiators in the enlarged flange forming the pull tab, substantially at the end of the fold lines along which the reinforcement strips .
  • These fracture initiators can be constituted by short notches punched in the edge of said enlarged rim with the same orientation as the fold lines corresponding on this rim to the reinforcing strips.
  • the reinforcing strips are preferably arranged on this sheet so as to leave small margins between their outer edges and the corresponding fold lines.
  • the invention is applicable to shaped packaging prismatic having a base (corresponding to the above-mentioned background) rectangular, triangular or in the shape of a circular sector.
  • a packaging package according to the invention is formed of a first sheet 1 (Figure 1) and a second sheet 2 (shown in gray in Figures 2 and 3). These are thin aluminum sheets.
  • the sheet 1 is shaped, by folding along the lines drawn in fine lines in Figure 1, into a shell comprising a rectangular bottom 3 and lateral faces 4, 5, 6 and 7 also rectangular, rising perpendicular to the plane of the bottom 3, to which edges 8, 9, 10, 11 are marginally connected, the corner folds appearing between the adjacent side faces being folded against the side faces 5 and 7 and their edges 9 and 11.
  • a determined quantity of cheese 34 (Gruyère paste or semi-salt, for example) over a height equal to the height h of the side faces 4, 5, 6 and 7.
  • the second sheet 2 of dimensions identical to those of the bottom 3, on which the edges 8, 9, 10, 11 are folded down.
  • edges are welded on the periphery of the sheet 2, over their entire length, except for one of the edges, know the one with the reference 8, where the solder is limited ite to its central region, as we will see later.
  • the outer face of the latter and the inner face of the sheet 1 are coated with a heat-sealable lacquer.
  • the rim 8 is wider than the others.
  • its corners are folded down by folding along lines 12, 13 oblique at 45 °.
  • a triangular tongue 15 is formed, by which the package can be opened.
  • this tongue By effecting a pull on this tongue (arrow 16), it is possible to tear off, along a double tear line corresponding to the folds 17 and 18 located between the side faces 5 and 7 and the bottom 3 and their extensions s extending on either side of the lateral face 4, of the rim 8 and optionally of the lateral face 6, a wide opening strip 19 taken from the sheet 1 and formed by the tongue 15, from the lateral face 4, of the bottom 3 and possibly of a part of the lateral face 6.
  • two narrow reinforcing strips 20, 21 are welded on the inner face of the sheet 1 along the folds 17, 18 cited above and their extensions. These strips 20, 21, rectilinear on the sheet 1 in its initial flat state, run over the rim 8, the lateral faces 4 and 6 and the bottom 3. They stop at some distance from the extreme limit of the rim 8. Opposite the corresponding ends of the strips 20, 21 are provided in the flange 8 two notches 22, 23 coinciding with the extensions of the folds 17, 18 and forming two tear caps which facilitate the start of the separation of the opening strip 19 along the outer edge of the reinforcement strips 20, 21.
  • the bands 20, 21 initially rectilinear form, on the side of the tongue 15, two successive right angles so that they extend parallel to each other, then are directed towards each other by end portions belonging to the tongue 15 and along the fold line 24 which is situated at the foot thereof and on which the tear caps 22, 23 are located, between the ends bands 20, 21.
  • FIGS. 2 and 3 show the theoretically ideal arrangement of the reinforcing strips 20, 21 according to which the outer edges of the latter coincide with the folds 17, 18 and their extensions, such as the initiators of rupture 22, 23.
  • the width a of the lateral parts of the rim 8 is less than half the width b of the bottom 3, so that after folding there remain uncovered central portions of the sheet 2, at 29, and of the tongue 15, at 30, allowing for the latter to locally weld to said sheet 2.
  • the central part 31 of the rim 8 has for its part a width c greater than a and equal to half of the aforementioned width b, which is also the width of the strip of opening 19, and this over a length e a little less than b so as to reveal notches 32.33 defining, after folding, the extent of the welding window 30, outside of which the corners folded into a triangle, which meet exactly along a center line 14, cover the entire inner face of the pull tab 15, preventing its sealing so as to ensure easy gripping thereof for the opening of the package.
