Definitions

  • the present invention relates to a method for manufacturing a flexible sheet packaging for cellulosic tissue products, the packaging thus obtained and the machine for carrying out the method.
  • Flexible sheet packaging for wrapping tissues packets, comprising a flexible sheet packaging provided on one of its faces with a trapezoidal pre-cut, the narrowest lower base of which supports a mounted adhesive tab. straddling this base, so that an adhesive part adheres to the trapezoidal part and another part to the rest of the face of the package.
  • a first object of the invention is therefore to propose a method of manufacturing a packaging in flexible sheets for cellulosic tissue products which no longer has the disadvantage of this step of positioning the adhesive tab.
  • Another object of the invention is to propose a manufacturing process which in addition to its simplification makes it possible to ensure easy gripping of the tongue for easy opening of the package.
  • This object is achieved by the fact that during the manufacturing process, in the step of pre-cutting the tongue, the angles of the tongue are cut and in the step of depositing the thermo-adhesive, it is deposited at a determined distance from the edge of the tongue so that this edge constitutes an easily liftable portion.
  • Another object of the invention is to provide a packaging in which the risk of tearing off the adhesive part of an opening and closing tongue of the packaging is eliminated.
  • the packaging comprises a continuous or discontinuous welding between two parts of the packaging going around the product to be packaged, this welding being interrupted at least once by a tab precut in this packaging and one of which zone in the vicinity of the narrowest part of this tab is completely cut out and has an adhesive zone which is adhered to the lower part of the packaging.
  • the pre-cut has a convex shape.
  • the precut has a trapezoidal shape.
  • the packaging has an upper face, a lower face, front and rear lateral sides.
  • the packaging is of revolution and has an upper and lower face.
  • the pre-cut is located on the upper or lower face.
  • the pre-cut is located on the sides.
  • Another object of the invention is to propose a machine for implementing the method.
  • a flexible sheet of packaging material such as for example polyethylene, preferably in the form of a strip (1), comprises a central part (10) and lateral parts (11, 12) delimited by longitudinal fold lines ( 13, 14) which constitute the upper and lower edges which form the periphery of the parallelepipedic packaging shown in FIG. 2.
  • the central part is subdivided into two parts, not necessarily of equal size, by a dotted line (8) which extends the cutting line represented by a cutting tool (2).
  • This line runs flush with the end of a pre-cut formed in one of the two parts (10A, 10B) delimited by the line (8).
  • This pre-cut (100) has edges (101, 102) partially pre-cut and in an advantageous variant of the invention, a portion (103), entirely cut, constituting the narrowest end of the tongue.
  • the pre-cuts (101, 102) may extend slightly beyond the zone (10) in the strip of material which constitutes the adjacent part, in this case, depending on the mode. shown in Figure (1), the strip (11). In a reverse arrangement, it would be the strip (12).
  • the strip (1) of material is split in two at the cutting tool (2) and forms two strips (10A, 10B) whose newly cut edges are referenced (15) for the part (10A), (16 ) for part (10B).
  • the packaging manufacturing machine After cutting this strip, and at regular intervals corresponding to the locations of the tongue (100), and in particular near the end (103) of this tongue, the packaging manufacturing machine installs a portion of thermocolle (7). After this step of placing the portion of thermo-adhesive (7), the manufacturing machine brings the edges (15, 16) corresponding to the parts (10A) and (10B) cut so that these edges overlap as represented on the portion of the figure delimited by the mixed lines (4, 5).
  • the superimposed parts of the central portions (10A, 10B) are welded together by a welding line (6) of a welding device of the manufacturing machine.
  • the pre-cuts constituting the tongues are arranged at regular intervals represented by the distance (d) corresponding approximately to the perimeter of the objects to be packaged plus a part allowing a slight superposition of the transverse cutting edges of the strip before welding and folding for constitute the packaging around the product.
  • the transverse cutting edges of the strip are represented by the mixed lines (3, 4, 5).
  • the part of the cut strip is folded so as to constitute the edges (40, 41, 42) represented by the fine lines in FIG. 1.
  • the packaging thus obtained in the case of a parallelepiped product to be packaged, comprises a front face (1) on which the tongue is located, opposite a rear face, two opposite lateral sides, an upper side and a side inferior.
  • the tongue (100) can be arranged on one of the upper or lower faces or on one of the lateral, upper or lower sides.
  • FIG. 3 represents a variant of packaging in which the tongue is precut in a convex shape, which allows, for example, the packaging of products having a shape of revolution, as shown in this figure.
  • this type of packaging is by no means limited to tissue paper packaging, but can also be applied to any type of product, such as towels, periodical linings, diapers, etc.
  • thermo-adhesive (7) applied to the part of the tongue (100) which is superimposed on a part (10B) of the lower strip makes it possible to keep the packaging closed before use. Easy opening by the user is obtained by pulling on the completely cut out part (103). The user extracts part of the products contained in the packaging and the thermo-adhesive having the property of retaining an adhesive quality, even after separation, then allows the user to close the packaging, so as to preserve the rest of the products which has not been used.
  • the machine for manufacturing the packaging does not require a transfer device for bringing this additional piece formed by the adhesive tongue is therefore simpler in its constitution.
