Definitions

  • the present invention relates to a plastics material envelope package including opening means for facilitating the opening of the package.
  • envelopes must be necessarily made of a plastics material having a comparatively high strength.
  • the aim of the present invention is to solve the above mentioned problem, by providing a plastics material envelope type of package including means for facilitating the opening of the package, allowing to open the package along preset cutting lines, without using scissors or the like.
  • a main object of the invention is to provide such a plastics material envelope package having built-in opening means, thereby greatly simplifying all the necessary operations.
  • Yet another object of the present invention is to provide such a plastics material envelope package which, owing to its specifically designed constructional characteristics, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a plastics material envelope package, including means for facilitating the opening of said package, which can be made by using easily commercially available elements and materials.
  • a plastics material envelope package including means for facilitating the opening of said package, said package comprising a plastics material holding body for holding articles in general therein, and being characterized in that said package comprises, associated with said body, a cutting device for at least partially cutting through said body.
  • Figure 1 is a perspective view showing the envelope package according to the present invention.
  • Figure 2 is a detail view showing, on an enlarged scale, a detail of a cutting device applied to the envelope package;
  • Figure 3 shows a setting operation for setting the cutting device for a use thereof
  • Figure 4 schematically shows an operating step for providing a cutting line
  • Figure 5 shows a modified embodiment of a cutting device, at the start of the operation for forming the cutting line
  • Figure 6 shows the cutting device performing a cutting operation.
  • the plastics material envelope package including means for facilitating the opening of the package, according to the present invention, which has been generally indicated by the reference number 1, comprises a package body 2 which is typically made of plastics material sheets which are peripherally heat sealed so as to provide an article holding region 3 which is advantageously put under a vacuum condition.
  • a main feature of the invention is that a cutting device is associated with the package body 2.
  • a throughgoing hole 10 arranged between the sealing lines 11, optionally arranged as ridges, is so formed as to practically house therein the cutting device which, according to the embodiment shown in figures 1 to 4, comprises a metal material strip 20 including a middle cut 21 defining two discrete flaps 22 and 23 separated by said cut and which, at the connection region to the strip 20 practically define a cutting point 24.
  • one of said flap comprises, at a free end portion thereof, indicated by the reference number 21a, an upward folded or bet portion, facilitating a gripping thereof.
  • said cutting device is typically connected, with a flat arrangement, to the package and, for using the package, by operating the folded gripping end portion 21a, one of said flaps, for example the flap 22 is upward lifted. Then, by providing a pulling force, the cutting region 24 is caused to perform at least a partial cutting through of the body, thereby providing the desired opening, as schematically shown in figure 4. Since the two flaps 22 and 23 are arranged in a straddling relationship with respect to the plastics material layer to be cut through, it is possible to perform, without any difficulties and danger, an accurate cutting through of the material, and, accordingly an easy opening of the package.
  • a modified embodiment of the cutting device is herein shown, as generally indicated by the reference number 30, which cutting device comprises a metal plate 31.
  • Said metal plate 31 comprises, at an end portion thereof, a folded leg 32 operating as a guiding element to be coupled with the cutting edge to provide and hold a preset cutting direction.
  • the cutting region in particular, is provided by a separating cut 33, defining a top flap 34 and a bottom flap 35, which can be arranged on the opposite faces of an element to be cut.
  • the invention provides cutting devices, which are directly coupled to a package for packaging products in general, and which are merely made starting from metal material plates or sheets, having a cut defining a bottom cutting region, thereby, by arranging the flaps separated by the cut one above and the other under the plate element forming the package body, it is possible to easily perform the cutting operation and easily open the package.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
