Definitions

  • a similar opening system has been already available for a long time on the market and it is the device for opening small purses and the like which were provided with two flexible steel sheets which opened by bending by means of a pressure exerted on their ends by fingers.
  • the device according to the present invention is different than the above mentioned system both as regards the particular shape and the material of the sheets 1 and as regards their specific tearing function during the opening action at the outer border with a sharp corner of the sheets 1 of the bag 2 and as regards the fact of being specifically used for opening sealed bags 2 .
  • FIG. 1 is an hand holding a typical bag 2 according to the present invention which is opened as a consequence of tearing the borders 3 of the mouth due to the compression C exerted on sheets 1 by the forefinger and the thumb.
  • the parallelogram shaped mouth is generated by grooves 5 made within the sheets 1 which weaken the local resisting moment thereof.
  • FIG. 2 is two pre-bent sheets 1 .
  • a top view of two juxtaposed sheets 1 (with the bag in the sealed condition), a top view of two curved sheets 1 (without internal stresses) and a side view with the rectangular section thereof below can be seen.
  • FIG. 3 is two sheets 1 with a variable thickness (the thickness is greater in the centre).
  • a top view of two juxtaposed sheets 1 , two sheets joined by a film 4 at two ends thereof slightly opened and a side view with the trapezoidal section thereof below can be seen.
  • FIG. 4 is two sheets 1 having each one a groove 5 .
  • a top view of the two juxtaposed sheets 5 with their two displaced grooves 5 , two just opened sheets with a parallelogram shape and a side view of the inner portions of the two sheets 1 with their two parallelogram sections below can be seen.
  • FIG. 5 is five types of sections suitable for the proper operation of the invention.
  • FIG. 6 is a strip portion made of any suitable material 7 upon which two adjoining sheets 1 arranged orthogonally to the length of the strip are glued or welded. The cut lines it and the folding line 1 p by 180° can be seen. Edges 6 to be glued or welded are shown too.
  • FIG. 7 is a strip portion made of any suitable material 7 upon which a series of two parallel sheets 1 is glued or welded, orthogonally to the strip length, which are drawn close to each other and spaced by a distance 2 s equal to twice their thickness. Each pair of sheets 1 is spaced from two adjacent ones by a distance equal to twice the length hs of a bag 2 . The cut lines It and the folding lines 1 p by 180° can be still seen. Edges 6 to be glued are shown too.
  • FIG. 8 is a strip portion made of any suitable material 7 upon which a series of pairs of parallel sheets 1 are glued or welded along the centre line of the strip, which are drawn close to each other and spaced by a distance 2 s equal to twice their thickness.
  • the distance between two adjoining pairs is equal to the width of two edges 6 .
  • the cut lines 1 t and the folding lines 1 p by 180° can be seen. Edges 6 to be glued or welded are shown too.
  • the distance among cuts is equal to the width of the bag 2 , while the length of bags is equal to one-half of the strip width.
  • the principle of this invention is to provide the use of two sheets 1 made of elastic material preferably plastic polymer which are juxtaposed with the bag 2 in the closed condition, even with variable sections along their length direction, each one of them having a length equal to one-half of the circumference of the mouth of the bag 2 , and such an height and thickness that lead to a controlled bending moving them apart at their central area and contemporaneously causing the border of the mouth of the bag 2 to be torn when a compression C is exerted on their ends, by two fingers.
  • Such two sheets 1 are generally welded or glued, preferably on the inside of the edge 6 to be opened of the bag 2 . Sometimes it can be useful also to apply them on the outside.
  • the orthogonal sections along said elastic sheets 1 can be different and such that it is easier to initially mutually moving them apart and moreover, as it will be shown below, the two closed borders of the mouth of the bag 2 can be accurately torn.
  • These actions can be easily carried out by a simple compression C of the two sheets 1 acting throughout their length for example between the thumb and the forefinger. The same hand used for opening them, obviously will be used afterwards for pouring the contents of the bag 2 when necessary.
  • the two sheets 1 can be already joined together, making only one sheet, by two of their distal ends by a short thin connection film 4 .
  • a short thin connection film 4 can be easily juxtaposed when they are folded one against the other by 180° together with the strip upon which they are glued or welded.
  • Sheets can be easily produced, depending on the shape of sections, both by molding and by extrusion with a subsequent cut 1 t parallel to their length.
  • the cut 1 t can also be made with an inclination in order to generate a sharp corner with an acute angle.
  • the simplest arrangement of such quick-opening on bags 2 to be filled is to prepare a strip made of paper or plastic material upon which two flexible sheets 1 are applied, perpendicularly to the strip length and at the same distance one to the other, one after another or joined 4 together by their ends.
  • the simplest ones are glueing in the case of paper and welding in the case of plastic material. Therefore the strip can be folded 1 p by 180° along its longitudinal centre line and then glued or welded along its two free side edges. Then the two sheets 1 are juxtaposed one upon the other, and in case they are glued by a Stick-no-stick adhesive.
  • the strip folded in this manner is cut 1 t at the desired length of the bags and then, or contemporaneously with the cutting 1 t it is welded or glued just above the two sheets 1 such that the glueing or welding contemporaneously make the closures of the bottom and mouth of each bag 2 .
  • the two free side edges 6 therefore can be glued or welded, after being in case laterally filled, by conventional filling machines in use on the market.
  • Such solution is also suitable for bags 2 that can be manually filled when the two juxtaposed sheets 1 are kept adherent each other by stick-no-stick adhesive. In this case the bending does not tear the paper or the plastic material but it unglues the two sheets 1 that will be glued again upon the release of the compression C.
  • a second process ( FIG. 7 ) for making bags 2 giving the same results is to apply two sheets 1 which are adjoining or already joined together 4 , such as in claim 5 , followed by other two equal adjoining sheets 1 spaced from the first two by a distance 2 s that is equal to twice their thickness which are arranged orthogonally to a strip whose width is twice the width of the bag plus two edges 6 intended for the lateral glueing or welding.
  • the two double sheets 1 along the strip are spaced from the following two by a distance equal to twice the length of the bag plus two edges 6 for the final glueing or welding of the bag bottom.
  • the strip is cut 1 t and welded or glued parallely to the sheets 1 at one-half the distance between two subsequent double sheets 1 .
  • Strip portions obtained in this way are folded 1 p by 180° between the two double adjoining sheets 1 thus the latter are juxtaposed. Therefore the side edges 6 are glued or welded. The bottom aperture will be then glued or welded after filling the bag 2 .
  • This solution is suitable for sealed bags 2 and they are opened always by a tearing action.
  • a third process ( FIG. 8 ) provides to apply at the
  • centre of the strip whose width is twice the length of the bags 2 plus two edges 6 to be welded or glued, plus twice the thickness 2 s of sheets 1 , and along all its length two parallel rows of adjoining sheets 1 spaced apart by a width 2 s that is twice the thickness of the sheets 1 .
  • the two double pairs of sheets 1 are spaced one another lengthwise of the strip by a distance that is twice an edge 6 for the lateral glueing or welding.
  • the strip is folded 1 p by 180° along its centre line that is at the same distance between the two rows of pairs of sheets 1 and therefore it is cut 1 t, orthogonally to the strip length, at the same distance between the relevant ends of two double pairs of adjoining sheets 1 .
  • Such strip portions then can be welded or glued at the two sides 6 of the bag and then filled and sealed at the bottom of the bag 2 . This process easily lends itself to line automation. Even in this case the manual opening occurs by a tearing action.
  • bags 2 are used for containing medicinal powders or food powders such as for example bags containing sugar doses intended for bars.
  • the number of packages and the cost of their contents will define the packaging method to be selected, which is more or less automatized depending on numerical, commercial and economic requirements.
  • any of said known processes can be easily modified only for applying the two flexible sheets 1 to each bag 2 which are the essential elements of the present invention, together with their peculiar use.
  • the bag 2 needs only to be taken by two fingers, preferably the forefinger and the thumb, placing the two fingertips on the distal ends of the two juxtaposed flexible sheets 1 of the closed bag 2 .
  • the two sheets 1 will bend outwardly tearing the edge 6 made of paper or plastic material glued or welded at or near the upper border with a sharp corner of the two sheets 1 .
  • the glued or welded closure will be carried out such to exert the proper resistance to tearing and therefore to the compression C made by the two fingers.
  • such force will be equal to about the force necessary for two fingers to grasp a coffee cup by its handle.
  • the closure will be easy to be opened but it will be sufficiently strong and safe.
  • the solution n. 3 is the one that best suits limited compression forces since corners of sheets ( 1 ) taking a parallelepiped shaped deformed configuration have two locations, at the two grooves 5 , wherein the pressure increases very quickly and where the tearing inevitably begins.
  • the equidistant displacement of the two grooves 5 on one part and on the other part from the centre of the two sheets 1 allows the quick-opening assembly to have a necessary stiffness thus avoiding the closure to be unintentionally bent on one side.
