Definitions

  • the present invention relates to a method for packaging deformable products in a packaging made of a semi-rigid material.
  • the blanks are first produced by continuous cutting and creasing of a strip of paper or cardboard.
  • the blanks are then transferred, one by one to a packaging station in which, just before the folding operation, a coating of glue is carried out on the areas of gluing of the blank, generally on the flaps.
  • This gluing is carried out on one of the sides of the blank using an adhesive, for example of the "PVA” or “HOTMELT” type, by glueers provided in the packaging machine.
  • the gluing process which takes place at the gluing zones to which the corresponding gluing zones are applied, during folding, is of the conventional type.
  • the adhesive solvent for example water
  • Bonding then occurs during drying.
  • glues of this type consists in that they cannot be applied to bonding zones of large dimensions, because of the risks of glue overflow which appear when the zones under pressure are brought into contact. paste, as well as possible degradations resulting from the absorption by paper or cardboard, of significant quantities of solvent.
  • the invention is based on two observations which make it possible to overcome this prejudice.
  • the first observation consists in that, in a pack of cigarettes of conventional type, the most important forces exerted on the glued parts are shear forces and not tear forces: this results from the specific design of cigarette packs and their mode of use, and in particular the fact that, unlike many packages, the stresses on the packages of cigaretes do not result from the weight of the contents of the package, but from external actions exerted on these outer faces , for example when the package is in a pocket or a bag. These external actions manifest themselves at the bonding level by shear stresses and not tearing. However, until now, no one had thought of using the adhesive strength to shear and not to tear.
  • the second observation shows that the quality of the fixing obtained using this type of glue improves over time, during the first days after bonding. This manifests itself particularly in the case where, after packaging, the packages are overwrapped and / or arranged one against the other, in bundles or cartridges. In this case, it is assumed that the slight pressure exerted on the packages contributes to increasing the quality of the sizing.
  • the invention therefore provides a packaging method taking advantage of the particularities of this adhesive.
  • this pre-gluing operation may be carried out during the printing and cutting of the blanks operation.
  • the pre-glued and dried blank can be handled by conventional means without risking contaminating the installation and, consequently, the following blanks. Likewise, there is no longer any fear of glue overflowing or deterioration of the paper or cardboard.
  • the pre-gluing zones may, for their part, exceed the dimensions of the gluing zones, these then being limited to the intersections of the pre-glued zones.
  • Another advantage of the method according to the invention consists in that it allows pre-gluing of areas located on the two faces of the blank, which was not possible with the usual adhesives, due to the problems of subsequent handling of the blank.
  • the invention also relates to a method comprising in combination bonding using a contact adhesive and bonding of the traditional type.
  • the blank 21, the two faces 21 ', 21' 'of which are shown in FIGS. 1 and 2, is used to make a pack of cigarettes such as that shown in FIG. 7.
  • This package in the closed state (solid lines), has a parallelepiped shape and includes two rectangular trapezoidal parts, namely: a body 22 and a cover 23, these two parts being open at their oblique face which constitutes the face assembly (plan P).
  • the small base 24 of the cover 23 consists of an extension of the large base 25 of the body 22, the separation between these two bases being embodied by a fold line 26 which allows the cover 23 to switch between an open position (broken lines) and a closed position (solid lines).
  • the blank 21 making this package is obtained by cutting and creasing a strip of semi-rigid cardboard of the same width as the blank, cutting it at the anterior end of the blank, defining a re-entrant trapezoidal shape while that performed at the posterior end defines a truncated triangular shape.
  • the small base of the re-entrant trapezoidal shape is extended by an appendage 28 of the same width but of short length.
  • the blank comprises two longitudinal fold lines 29, 30 the spacing of which corresponds to the width of the packet of cigarettes that is to be obtained, these two fold lines 29, 30, delimiting a central strip, bordered by two lateral strips of width equal to the thickness of the package.
  • transverse fold lines T1 to T6 which extend over the entire width of the central strip 31 of the blank 21 and are extended at the side strips by cutouts D1 to D5 - D'1 to D '5.
  • the first fold line T1 defines with the front edge of the central strip 31, a rectangular area P plate corresponding to the front face of the cover 23 and, with the oblique front edges of the two lateral strips, two flaps R1, R'1 of trapezoidal shape.
  • the second fold line T2 defines with the first, in the central strip 31, a rectangular area P2 corresponding to the upper face of the cover 23 and of width equal to that of the package and, at the level of the side strips 1 ', 1' ' , two rectangular flaps R2, R'2.
  • the third fold line T3 is extended by two oblique cuts D3, D'3 which extend parallel to the oblique edges of the reentrant trapezoidal shape and the truncated triangular shape. It defines with the second line T2 a relatively narrow rectangular area P plate which constitutes the rear face of the cover 23 and, at the level of the lateral strips 1 '', 1 ', two trapezoidal areas R3, R'3 which constitute the side faces of the cover .
  • the fourth fold line T4 defines with the third line a rectangular area P4 which corresponds to the rear face of the body of the package, bordered by two lateral areas R4, R'4 of trapezoidal shape which partially constitute the side walls of said body.
  • the fifth fold line T5 defines with the fourth, a rectangular area P5 constituting the bottom of the body, this area P5 being bordered by two rectangular areas serving as flaps R5, R'5.
  • This fifth fold line also defines, with the front edge of the blank, a rectangular area P6 constituting the rear face of the package body.
  • This area P6 is bordered by two lateral areas R6, R'6, which constitute the lateral faces of the body, and by the appendage 28.
  • the latter is preferably connected to the area P6 via a line creasing or embossing T6 of large dimensions, so as to obtain a good mutual positioning, facing the front face of the cover 23 when the latter is in the closed position.
  • the method of folding the blank 21, in order to obtain the pack shown in FIG. 5, is of the conventional type and will therefore not be indicated in detail. To facilitate understanding, the direction of the folds has been indicated by arrows.
  • the various zones which must be glued are pre-glued and then dried, using a contact adhesive such as than previously defined.
  • this pre-gluing is carried out on the two faces of the blank in areas indicated by geometric figures such as rectangles or numbered triangles. According to the numbering, an area carrying a number is intended to be pasted on an area bearing the same number but assigned the letter A.
  • the outer face of the blank comprises zones 4A, 5A - 2A, 3A - 6A, 7A - 8A, 9A respectively distributed over the flaps R'2, R2, the flaps R'3, R3, the ranges R4, R ' 4, and the flaps R'5, R5.
  • the inner face of the blank comprises, for its part, zones 2, 3 and 6, 7 distributed over the flaps R'1, R1 and the lateral areas R6, R'6. It further comprises two rectangular areas 4, 5 made on the area P2 facing the flaps R2, R'2 and two rectangular areas 8, 9 made on the area P5 facing the flaps R'5, R5.
  • the appendix 28 can undergo, after folding, a pre-gluing using an infinite open time glue allowing the repeated opening and closing of the package, ensuring a better seal.
  • appendix 28 is extended by two trapezoidal tabs 28 ', 28' 'whose large base extends parallel and at a short distance and over the entire length of the oblique ends of the lateral pads R6, R '6.
  • These tabs 28 ', 28' ' are intended to be applied and glued to the lateral faces R1, R'1 of the cover 23 and therefore have, on the outside of the blank 21, two pre-gluing zones 2'A , 3'A respectively, intended to be applied on two corresponding pre-gluing zones 2 ', 3' provided on the lateral faces R1, R'1 of the cover on the inside of the blank.
  • the tongues 28 ', 28' ' are fixed by easy-break means, for example narrow links, at the oblique ends of the lateral areas R6, R'6, so as to allow the opening of the cover 23 by a consumer .
  • easy-break means for example narrow links
  • the trapezoidal areas R3, R'3 have, at the cutouts, notches E1, E2 of shapes complementary to those of the tongues 28, 28 '.
  • the areas of one side of the blank located at the level of the pre-glued areas carried on the other side of the blank can be covered with a repellent varnish to avoid adhesion of the blanks to each other, when they are stacked.
  • the use of the blank described above can be intended for the end user. In this case, it can be offered to the customer, separately, or be integrated into a cartridge of 5 to 10 packages.
  • the blank pre-gluing zones are not in contact with their counterparts and will not be active. They can therefore fulfill their role during the shaping of the product. This can be very easily done by hand by the consumer.
  • the blank does not have an appendage 28.
  • it has a rectangular flap R8 connected to the front edge of the area P1 by a transverse fold line T8.
  • the flap R8 and the pad P1 carry two longitudinal pre-gluing zones 1, 1A - 1 ', 1'A, spaced from one another, which allow the flap R8 to be fixed against the pad P1 in the folded position.
  • the lateral areas respectively carry two longitudinal pre-gluing zones 12 starting from the oblique cutouts D3, D'3.
  • the rectangular area P6 carries two longitudinal pre-gluing zones 11.
  • the flap R8 On the side of the outer face of the blank, the flap R8 carries a transverse pre-gluing zone 10, while the pre-gluing zones 6A, 7A have two rectangular notches E3, E4 making it possible to avoid any sticking with the pads 12 when the blanks are stacked.
  • the blank further comprises a separate collar 32, substantially C-shaped comprising a central core 33 and two lateral wings 34, 35.
  • This collar 32 the width of which corresponds to that of the blank 21, comprises two lines of folding L1, L2 corresponding to the longitudinal folding lines 29, 30.
  • the central core 33 comprises two longitudinal pre-gluing zones 10A, 11A intended to be applied temporarily on the pad 10 and definitively on the pads 11.
  • the lateral wings 34, 35 comprise two longitudinal pre-gluing zones 12A intended to be applied and to stick permanently against the zones 12.
  • This arrangement ensures better closure of the box thanks to the contacting of the pre-glued areas 10 and 10A. It also improves both the tightness of the package before consumption and its appearance during consumption thanks to better retention in the closed position of the cover after operation to extract cigarettes.
  • the cigarette pack shown in FIGS. 8, 9 and 10 comprises a tubular case 76 of parallelepiped shape in which engages and can slide a drawer 36 containing the cigarettes.
  • the blank used to make the case 37 consists of a rectangular cardboard strip provided with four transverse fold lines L3 to L6 which delimit the two main faces FP1, FP2 of the case, its two lateral faces FT1, FT2 and a tab PF fixing.
  • the fixing tab PF On the side of the outer face of the blank, the fixing tab PF carries a pre-gluing area 41, while on the inside, the edge of the blank opposite the tab PF, carries a corresponding pre-gluing area 41A.
  • the invention eliminates the heating means which ensure bonding on traditional machines and therefore ensures better preservation of the organoleptic qualities of cigarettes which are not subjected to heat sources during package manufacturing. It also brings a simplification of the materials and an improvement of their efficiency. Because it allows larger bonding areas, it increases the tightness of cigarette packages.
