Definitions

• the object of the invention is a flexible package particularly for liquid, pasty products and the like, in particular food products such as beverages, fruit juices, yoghurt, etc.
• the package according to the invention can be, for example, a package of the stand-up type, i.e. self-supporting when filled with the product, having a reinforced support base wherefi'om two side walls rise up, heat welded along the upper and side edges, or it can be a "form and fill" parallelepiped container with lower and upper closures of the gusset type.
• These packages are normally opened by cutting an upper corner at said weld or by tearing the package at a preformed notch.
• the object of the invention is that of eliminating the aforementioned disadvantages, providing a package particularly for liquid products or containing at least in part a liquid, pasty product or the like, which allows a controlled release of the product and secure retaining of the product in the package when the latter is not used after opening.
• Another object of the invention is that of providing such a package which is self- supporting, so that several packages can be stacked one on the other during storage and/or transport.
• the package according to the invention of the stand-up or parallelepiped type, having a linear head weld parallel to the level of the liquid, also has, at at least one of the two upper corners of the package, in proximity of the end of said linear head weld, two side welds which join at the centre line of the package, determining a V configuration, the vertex thereof is positioned at the end of said linear head weld.
• the abovementioned linear head weld is formed in close proximity of the level of the liquid, such as to reduce to a minimum the head space of the package and make it self- supporting, in such a way that several packages can be stacked one on the other.
• Figures 1 and 2 are two perspective views from opposite angles of a package according to the invention of the stand-up type
• Figure 3 is a front plan view of the package of Figures 1 and 2;
• Figure 4 shows the package of the previous drawings in conditions of use, after opening
• Figure 5 is a perspective view of a package according to the invention with parallelepiped shape of the "form and fill" type
• Figure 6 is a front elevation view of the package of Figure 5;
• Figure 7 is a side elevation view
• Figure 8 is a view from below
• Figure 9 is a perspective view of a package according to the invention such as that of Figure 5, with a different closure weld.
• a package or container 1 is illustrated of the so-called stand-up type, i.e. self-supporting, having a support base 2 with a perimeter weld 3 which develops along the lower edge of the package and rises along two opposite side zones 3'.
• Two opposed walls 4, 5 rise up from the base 2, joined one to the other by welds 6 developing along two opposed side edges of the package which is then closed above by means of a linear or transverse head weld 7 which extends between the aforementioned side welds 6.
• the linear head weld 7 is formed in close proximity of the level of the product contained in the package 1, so as to reduce the residual head space of the package, thus making the package more rigid and able to support the weight of other packages stacked thereon.
• the component material of the package 1 is normally a material in flexible multi-layer sheet, with the internal layer which can be heat welded.
• pairs of side welds 10, 11 are formed between superimposed zones of each of the abovementioned side walls 4, 5. These pairs of side welds 10, 11 are slanted upwards and towards the exterior of the package and tend to join at the centre line of the package itself, forming a V with the vertex in proximity of a corresponding upper corner 8 of the package.
• the pairs of side welds 10, 11 are provided at both the upper comers 8 of the package 1, yet it is clear that they could be provided at only one of these corners.
• Figure 4 shows schematically the package 1 open during dispensing of its content.
• a cut is made at an upper corner 8 of the package, possibly involving also the ends of the pairs of opposed welds 10, 11, so as to determine an aperture 12 through which the liquid 13 is dispensed.
• Provision of the pair of side welds 10, 11 determines a flattening of the package in proximity of the corresponding upper corner 8, such that when this corner is cut to determine the aperture 12, there is no release of liquid from the container, a release which only takes place in a controlled manner, pressing the opposed walls 4, 5 of the package, as shown schematically in Figure 4.
• Figures 5 to 8 show a package, denoted by reference numeral V, having exactly the same innovative features of the stand-up package of Figures 1 to 4.
• the package is of a substantially parallelepiped shape, of the so-called "form and fill” type, obtained in a manner in itself known from a strip of material in a multilayer sheet, with an internal layer which can be heat welded, which is made to advance along a spindle normally positioned vertically, around which it is closed by means of a longitudinal weld ⁇ ', which is positioned vertically on a wall of the formed package, so as to form a tubular part which is closed below by means of a first transverse weld and, after having been filled with the product, is cut and closed above by means of an additional transverse weld which constitutes the abovementioned head weld 7.
• a gusset fold 20 is then formed, in itself known,
• the linear head weld 7, as in the case of the package of Figures 1 to 4, is formed in proximity of the level of the liquid, so as to reduce the head space, and the pairs of opposed side welds 10, 11 determine, as in the previous case, V configurations with the vertices in proximity of the upper corners 8 of the package.
• Figure 9 differs from that of Figures 5-8 due to the fact that the longitudinal closure weld 6' is positioned at a vertical edge 20 of the package 1", which has "fin" bends and welds 21 at the other vertical edges.
