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 placed flat on the surface of the product to be conditioned previously placed in said shell.
  • the parties. 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 inner sides of the first sheet respectively and the outer sides 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 side face constitutes a wide opening strip which must tear along the fold lines bordering said side face and the bottom by pulling on a tongue formed by the edge of this last lateral face, wider than the other edges.
  • 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 opposite side face to the pull tab and on the other side to a part of the enlarged flange forming said tab, so that the reinforcement strips, which extend parallel or substantially parallel to each other over most of their length, are directed towards each other over the rest of their length - after folding the first sheet - by end 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 rim is such that between the two folded corners of the tab remain uncovered heat sealable portions of the first sheet and the second sheet facing.
  • the width of the widened rim is such that between the two folded corners of the tab remain uncovered heat sealable portions of the first sheet and the second sheet facing.
  • the enlarged rim is additionally enlarged in a central part of its border, over a length less than the width of the opening strip, so that the entire surface of the pull tab is covered by the folded corners, with the sole exception of the above heat-sealable portions ,. these being delimited by a small window defined by the terminal notches appearing at the corners of said rim due to the presence of said enlarged central part.
  • 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 widened edge forming the pull tab, substantially at the end of the fold lines along which the reinforcing 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 reinforcement 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 packages of prismatic shape having a base (corresponding to the above-mentioned bottom) 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 embossed in fine lines in FIG. 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) on an equal height at the height h of the lateral faces 4, 5, 6 and 7.
  • the second sheet 2 On the surface of the cheese is deposited 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, namely the one which bears the reference 8, where the weld is limited to its central region, as will be seen below. .
  • 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 1 B others.
  • its corners are folded down by folding along lines 12, 13 oblique at 45 °.
  • a triangular tongue 15 is formed, by means of 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 side face 4, of the rim 8 and possibly of the side face 6, a wide opening strip 19 taken from the sheet 1 and formed by the tongue 15, from the side 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 aforesaid folds 17, 18 and their extensions.
  • 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 reinforcing strips 20, 21.
  • the bands 20, 21 initially rectilinear (FIG. 1) form, on the side of the tongue 15, two successive right angles so that they extend parallel to each other, then direct towards each other by end portions belonging to the tongue 15 and along the fold line 24 which is located at the foot thereof and on which the tear caps 22, 23 are located, between the ends of the bands 20, 21.
  • These act as guide bands for the progression of the tear lines (FIG. 3) firstly along the aforementioned fold line 24, then along lines 25, 26 bordering the side face 4, then along lines 17, 18 and finally optionally along lines 27, 28 bordering the opposite side face 6, so as to provide wide access to the cheese 34 contained in the packaging.
  • FIGS. 2 and 3 show the theoretically ideal arrangement of the reinforcement strips 20, 21 according to which the outer edges of the latter coincide with the folds 17, 18 and their extensions, like the initiations 22, 23. But in practice it is necessary to take account of the manufacturing tolerances affecting the positioning of the strips 20, 21. So that they never have an unfavorable position relative to the primers 22, 23 ,. they should be shifted slightly towards each other, as shown in Figure 1, providing a small margin d between their outer edges and the corresponding folds.
  • 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 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 opening strip 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 triangular folded corners, which meet exactly along a median line 14, cover the entire inner face of the pull tab 15, preventing its sealing so as to ensure easy gripping thereof ci for opening the package.
