Definitions
- the present invention refers to a package made of flexible material, for granular, pasty or liquid products, provided with a tear-off or tearing opening.
- the package according to the invention can be of any known type, for example stand-up package, that is, which is self-supporting when filled with the product, having a reinforced base, from which extend two side walls heat-sealed along the side and top edges, or can be a parallelepiped package with upper and lower bellows closures.
- Packages of the above type, or other similar ones, with tearing opening have a cut or notch near the upper edge of the package, at one side thereof, to promote tearing of the material, which should proceed parallel to the upper edge of the package, something which does not normally happen.
- a cut should be made, normally by laser, in the outer layer, for example of polyester, of the normally multilayer material that forms the package.
- US 5,552,202 discloses a tear guide arrangement for opening a package comprising a pair of opposing base strips and a pair of opposing tear guide strips.
- the base strips are composed of resilient polymeric material
- the tear guide strips are composed of a stiff or tough polymeric material having a substantially higher tensile strength than the resilient material of the base strips.
- the stiff polymeric material of the tear guide strips ensures that the tear guide strips separate cleanly from the respective base strips and this stiff material provides the mass essential to a bond rupture.
- Object of the invention is to overcome the drawbacks of the above-mentioned systems of the prior art, by providing a package that ensures perfectly straight tearing during the opening stage.
- Another object of the invention is that of providing such a package with tearing opening that is simple and cheap to make.
- Figure 1 is a plan view from the inside of a die-cut blank from which a package with tearing opening according to the invention can be obtained;
- Figure 2 is an enlarged view of the top right corner of the die-cut blank of Figure 1;
- Figures 3 and 4 show diagrammatically two successive stages in the formation of a package according to the invention;
- Figure 5 is an enlargement of a detail of the package of Figure 4.
- Figure 6 is a view like that of Figure 5 showing the start of the tearing stage
- a purely exemplifying package indicated by reference numeral 10, to which can be applied the tearing opening system of the present invention, which will be described in greater detail below, has a substantially parallelepiped shape, and has a bottom wall or base 1 1, a top wall 12, a front wall 13, a rear wall 14 and two side walls 15 and 16.
- This package is formed starting from a strip of multilayer sheet material, with the inner layer heat-sealable, which is fed along a mandrel normally disposed vertically, around which it is closed by means of a longitudinal weld S so as to form a tube which is closed at the bottom by means of a transverse heat seal SI followed by a bellows fold Fl ( Figure 4), after having been cut to the right length to form the package 10.
- the tube closed at the bottom in the form of a bag, is filled with a pre-set amount of granular, pasty or liquid product, and is subsequently closed at the top by means of a further transverse weld SP and subsequent bellows folding F2.
- Figure 1 shows the development of the package 10 seen from the inside, with the fold lines to obtain the package indicated.
- the material forming the package is normally a multilayer material, with an inner heat-sealable layer, for example polyethylene and possibly an intermediate barrier layer, such as aluminium.
- the outer layer is advantageously polyester.
- the strip or ribbon 3 is heat-sealable on both sides, so as to be able to be heat-sealed to the inside wall of the package 10 and allow the welds to be made to obtain a tight seal of the package, in the case in point the vertical weld S in the area where the strip is applied.
- the strip 3 is advantageously also made of multilayer sheet material, the outer heat- sealable layers of which are polyethylene or derivatives thereof, for example,
- the strip 3, or rather the two slices 4, 5 separated by the longitudinal cut 6, are disposed on the inside of the package 10 at least on the opposite front 13 and rear 14 walls as outlined in Figure 3.
- a notch 20, aligned with the cutting line 6 of the strip 3 ( Figure 5) is made at a side edge of the package, acting as a tear promoter.
- the invention achieves the intended object even with minimum thicknesses of the pre-cut strip 3, but it is obvious that the greater its thickness, the greater the guarantee that the tear will follow the separation line 6 of the strip.
- the applicant has performed numerous tests on packages of various types and has been able to verify the perfect performance of the tearing opening system according to the invention.
- the pre-cut strip 3 has been provided along the entire horizontal extent of the package, but it is obvious that it can be provided in pre-set areas which come to be opposed in the formed package, preferably reaching a side edge thereof, especially if complete opening of the package is not required.
- the tearing opening system according to the invention can be applied to other types of package, for example with "fin" seals along the four vertical edges of the package, as well as to stand-up packages, and so forth.
