Definitions

  • the present invention relates to a flexible container of the pouch type made of material in film form.
  • the container is particularly but not exclusively suitable for containing food products such as candies, chocolates, confectionery, et cetera.
  • the flexible containers of many food products are made of material in film form, for example polypropylene, and are derived from a tubular element that is shaped appropriately and forms front faces and sides with folds, formed by means of a longitudinal heat-seal and by transverse heat-seals of the two ends.
  • the container does not open completely but opens only partially, so that the user, for example, can extract only some of the products and the container can continue to perform its containment functions.
  • the aim of the present invention is to provide a pouch-type flexible container, provided starting from a film by means of heat-seals for preserving products, which can be opened easily, and then reclosed in order to retain inside it the unused products.
  • An object of the present invention is to provide an easy-opening, reclosable flexible container that can be manufactured with automated systems.
  • Another object of the present invention is to provide an easy-opening reclosable flexible container that can be manufactured with low production costs.
  • a flexible container of the type derived from a shaped tubular body formed by a film with a longitudinal heat-seal and by transverse heat-seals of the two ends said container being characterized in that at least one corner region thereof has, at its transverse edge in the region of said transverse heat-seal, a tear notch so as to produce, by pulling, the tearing of a portion of said film that comprises a part of the transverse heat-seal and a part of the tubular wall, freeing a corresponding flap of wall that is provided at least partially internally with low-stickiness adhesive protected by a removable film, said flap being foldable back onto the remaining portion of the container so as to close it by temporary sticking.
  • FIG. 1 is a perspective view of a container according to the invention in the closed configuration
  • FIG. 2 is a perspective view of the container of FIG. 1 during opening
  • FIG. 3 is a perspective view of the upper part of the container of FIG. 1 in the open condition
  • FIG. 4 is a perspective view of the upper part of the container of FIG. 1 in the open condition and during reclosing;
  • FIG. 5 is a perspective view of the upper part of the container of FIG. 1 in the reclosed condition
  • FIG. 6 is a sectional view of the container in the configuration of FIG. 1;
  • FIG. 7 is a sectional view of the container in the configuration of FIG. 5.
  • an easy-opening reclosable flexible container is generally designated by the reference numeral 10 and is obtained starting from a film that forms a tubular body 12 , inside which products 11 are accommodated; transverse heat-seals 13 are provided on said tubular body at the two ends.
  • the film which is generally wound in rolls, is unrolled and folded so as to form a continuous tubular body by means of a longitudinal heat-seal 14 ; transverse heat-seals 13 and cuts then form the body 12 , which has two facing walls 15 .
  • the longitudinal heat-seal 14 is provided substantially at the longitudinal central region in this case of a wall 15 , so as to form an external fin.
  • a corner region 16 can have a tear line 17 that is shaped so as to tear, by pulling, a portion 18 of said film that comprises a part 13 a of the transverse heat-seal 13 and a part 15 a of the tubular wall 15 , releasing a corresponding flap of wall 15 b.
  • the line 17 therefore lies diagonally at a wall 15 and follows the corresponding side 23 and the inner region of the wall 15 that is adjacent to the heat-seal 13 .
  • the two walls 15 are heat-sealed locally so as to constitute a retention element for interrupting the fracture formed by the line 17 .
  • the flap of wall 15 b is provided at least partially internally with low-stickiness adhesive 21 protected by a removable film 24 .
  • low-stickiness adhesive is used to designate an adhesive that allows to join and separate two surfaces several times before losing its adhesive effect.
  • the flap 15 b can be folded conveniently back onto the remaining portion of the container 10 so as to close it by temporary gluing, as shown in FIG. 5.
  • the flexible container according to the invention ensures easier opening for access to the products and the possibility of reclosure in order to retain inside it the unused products.
  • Opening and reclosing can be performed until the contained products have been used up completely.
  • Another advantage consists in that the flexible container according to the invention has an extremely simple constructive structure.
  • the flexible container according to the invention can be produced with an automated procedure.
  • Another advantage is the fact that the container according to the invention can be produced at very low production and manufacturing costs.
  • the materials employed may be any according to requirements.
