Description

  • The present invention relates to a flexible package according to the preamble of claim 1 [ EP 0 540 923 A1 ]. In general, it relates to the packaging technique of bags made of flexible material, and in particular concerns hermetic bags that can be opened and hermetically re-closed.
  • Several types of sealed bags are known that are provided with systems of opening and re-closing (e.g. US 2002/0182359 A1 and EP 0 546 369 A1 ). In all these known systems the problem of the hermetic re-closing upon partial serving still persists. The problem is due to the fact that after the first few openings, especially when the content is powdery, the adhesiveness of the flexible re-closing devices decreases significantly.
  • The solution suggested by the present invention, including a vacuum sealing as defined in claim 1, successfully resolves problems that still challenge this technological field.
  • The invention is now explained by the following description with reference to the figures of the drawings attached as a unrestrictive example.
    • Figure 1 represents schematically a flexible bag (5) provided with an adhesive label (2) with a non-stick prehensile flap (3) and warranty seals (4) to reveal signs of alteration of the sealed package. One might notice indicated with broken line the easy-open below area (1) on the side of the bag by the already mentioned adhesive label (2). A dotted line indicates the fragile area of the warranty seals (4).
    • Figure 2 represents the bag of figure (1) after an opening operation. It can be noticed the configuration of the open bag (5) and the position of the label (2) directed upwards. It can be noticed also the two warranty seals that highlight the breaking of the fragile lines of seals (4). In this figure 2 it can be noticed the presence of the wide opening (1) corresponding to the dotted line of the previous figure. It is evident that the adhesive part of the adhesive label (2) does not come in touch with the powdery product poured outwards.
    • Figure 3 represents the configuration of the bag in hermetic closing position. In this figure the breaking of the seals (4) in showed.
    • Figure 4 represents a flexible bag (5) packaged under vacuum and its squared parallelepipedic shape and its perfect hermetic sealing are highlighted. The airtight sealing is guaranteed even with the presence of the facilitated opening area (1), of the adhesive label (2) pushed by the external atmosphere against the sealed bag (5). It can be noticed that the dotted areas (4), still intact and guaranteed sealed, are also highlighted.
    • Figure 5 represents the bag of figure (4) after the operation of opening of the label (2) pulled upwards through the prehensile flap (3). It can be noticed that the package does not have the parallelepipedic shape because of the isobaric conditions created after the opening.
    • Figure 6 shows the stance that the bag takes after the hermetic closing, which is of course not in vacuum conditions anymore. The violation of the warranty seals (4) can also be observed.
  • In the figures each single detail is marked as follows:
    • 1 indicates an area with facilitated opening previously created upon the strip of flexible material to be packaged in hermetic bags.
    • 2 indicates an adhesive label.
    • 3 indicates a non-stick prehensile flap.
    • 4 indicates fragile area that function as warranty seals.
    • 5 indicates a flexible bag.
  • The evidence of the figures highlights the simplicity of the invention and its reliability also for airtight under-vacuum bags.
  • The invention of course allows for several variations of practical realization as far as the proportioning and the structural dimensioning are concerned and as well as the materials used in the realization of the bags wherein the scope of the invention is defined by the claims.

Claims (6)

  1. A flexible package having a body containing a powdery product, the body having essentially a square parallelepiped shape, and a hermetically sealed re-closable opening, wherein a part of the body is provided with an easy-open area (1) and wherein an adhesive label (2) is externally attached to the body so as to be pulled upwards for opening the easy-open area (1) and to be adhered to the body so as to assure hermetic sealing even after opening and re-closing, wherein the adhesive label (2) is provided with a prehensile flap (3) that facilitates its opening operation, wherein said prehensile flap (3) is located at a lower part of the label (2) to perform the upwards opening and to allow the serving of the content without soiling the adhesive interior of said label (2) during the pouring of the content,
    characterized in that
    the package is sealed under vacuum.
  2. The package of claim 1, characterized in that the adhesive label (2) assures the initial hermetic conditions of the bag packaged under vacuum, despite the presence of the easy-open area (1).
  3. The package of claim 1 or 2, characterized in that the adhesive label (2) is provided with special fragile areas (4) that perform the function of warrant seals to reveal alterations to hermetic bag.
  4. The package of any of claims 1 to 3, characterized in that the package is sealed at a top surface of the body.
  5. The package of claim 4, characterized in that a sealing portion projects upwards from the top surface.
  6. The package of claim 1, characterized in that the re-closable opening is provided at a side face of the package.
