Definitions

  • the present description refers to packaging techniques and in particular it regards the techniques that allow making multiple package.
  • flowpack (at times also called form-fill-seal or ffs) has been consolidated over the years.
  • patent literature - a packaging sheet material which is unwound from a reel is shaped according to a general channel-like configuration (usually open towards the bottom) which allows the introduction of the products into the package.
  • the free branches of the channel-like configuration are then coupled to each other in such a manner to provide a longitudinal sealing line ("fin") .
  • the tubular blank thus formed, with the products located therein, is thus subjected to welding and transverse cutting, to give rise to single packages.
  • the welding heads lead to flattening in intermediate positions between the products, and transverse sealing lines - at which the cutting operation is performed in such a manner to cause the separation of the single packages - are formed in the flattened zones.
  • multipack packages of the type currently referred to as "multipack" . These are packages are made up of several single flowpack packages grouped and inserted into a larger flowpack package.
  • the abovementioned sealing lines may not be easy to provide in cases where the package already contains products therein.
  • the abovementioned sealing lines may end up being quite strong with respect to the tearing force intended to separate the single packages from each other according to the methods described in the foregoing. This fact may lead, for example, to the need of subjecting the abovementioned sealing lines to score-line or punching treatments, intended to facilitate breaking when separating the single packages.
  • Document US-B-7 114 309 taken as a model for the preamble of claim 1 hereinafter, describes a solution for simultaneously providing two bag packages starting from a single roll of sheet material initially W-shaped (or shaped to form a double U) .
  • the abovementioned bag packages are filled by gravity operating from the top and closed by means of a system substantially similar to a zip closure system.
  • the present invention has the object of providing a solution capable of allowing to provide multiple packages avoiding the relevant drawbacks of the solutions according to the priorart previously referred to.
  • Various embodiments of the corresponding package give rise to a multiple package (for example a double package) wherein the single packages are actually structurally identical to each other and/or can be separated from each other through a simultaneously easy and safe separation action, avoiding any risk of unwanted inadvertent opening of one of the packages subjected to separation.
  • FIG. 7 illustrates the characteristics of the package adapted to be manufactured through the method described herein, in a more detailed manner
  • FIG. 8 schematically represents an ideal side elevational view of a system for implementing the method described herein.
  • reference number 10 is used to indicate a packaging sheet material with two opposite surfaces 10a and 10b having - at least on one side of the extension thereof - different weldability characteristics with respect to each other.
  • the sheet 10 may be represented by a "coupled" aluminium sheet, i.e. coated - on the surface 10a - with plastic heat-weldable material (or ultrasonically weldable material), such as polyethylene .
  • the aluminium material is not coated except at a strip 10c (which can be matched with a homologous line 10c' located in a position specularly symmetric to line 10c with respect to the bending configuration better described hereinafter) , in cases where a line made of heat- weldable plastic material (or ultrasonically weldable material) such as polyethylene is applied on the aluminium material.
  • the lines 10c and 10c' may be both continuous and discontinuous.
  • the sheet 10 be made up of non-heat-weldable plastic material whose surface 10a is treated with heat-welding lacquer or laminated with a welding layer, while - on the contrary - on surface 10b, only at line 10c (and, if present, at line 10c') it is made heat- welding by applying a strip of heat-welding lacquer.
  • Figure 2 shows a first operation for shaping the sheet 10 (according to an embodiment, the sheet 10 is in the form of a roll unwinding from a reel B - also see figure 8), according to a general U-shaped configuration.
  • Such first U-shaping leads to surfaces 10a and 10b being turned, respectively, outwards and inwards the U-shaped configuration.
  • Reference number 100 indicates a welding tool (for example a heat-welding tool with clamps or opposite counter-rotating wheels/rollers) which "chokes" the U- shaped configuration at line 10c (and at symmetric line 10c', if present) as schematically represented in the passage from figures 2 to 3 of the attached drawings. All this causing the two branches of the U-shaped configuration of the sheet roll 10 moving forward to be connected to each other by a longitudinal sealing line 12 (defined by line 10c, and symmetric line 10c' , if present) thus conferring the blank obtained starting from the sheet material 10 a shape approximately definable as an omega or "comet-like" shape.
  • a welding tool for example a heat-welding tool with clamps or opposite counter-rotating wheels/rollers
  • reference 14 defines a cutting line performed by means of a tool (for example a rotating knife) which operates on the sheet roll material 10 which moves forward at the body of the omega or comet- shaped element (located at a lower position) .
  • a tool for example a rotating knife
  • the two branches of the previously omega- shaped element - or the two tail branches of the comet- shaped element - are folded downwards in a manner such to give rise, within the sheet/roll 10, to two adjacent channel-shaped parts (and open downwards, in figure 4) .
  • each of the two adjacent channel-shaped parts has a web region and two lateral branches (symmetric or, like in the example herein illustrated, asymmetric, for reasons better explained hereinafter) extended starting from the web region;
  • the two adjacent channel-shaped parts thus have two "inner” lateral branches adjacent and connected by the line 12 which is extended in an intermediate position between the respective web region and the respective distal strip 14a, made free due to the cutting action performed along the line 14 (see figure 3) .
  • the line 12 (hence line 10c - and line 10c', if present) is provided for in a position adjacent to the web regions of the two channel-shaped parts .
  • the sequence of the abovementioned operations leads to: imparting a first ⁇ -shape to the packaging material 10, choking the aforementioned first U-shaped element, obtaining the tear-releasable connection line 12 as the line for connecting the two branches of the first U-shaped element; in particular, the line 12 is located at a choking point, hence said sheet material 10 acquires a choked configuration having a head part and two tail branches,
  • the packaging blank having the two channel-shaped parts thus obtained (open downwards in the illustrated embodiment) is suitable to be moved forward to the products loading zone of a generally traditional flowpack machine modified to supply the products moving forward in adjacent pairs inside the two channel-shaped parts, wherein the respective products - or product unit groups - P are inserted (operating from the bottom, according to the most common flowpack technique) inside the two channel- shaped parts .
  • the free strips of the two channel-shaped parts are adjacent to each other in such a manner to form a stratified structure indicated in its entirety with 16.
  • the "outer" strips 14b are longer than the "inner” strips 14a by a length about equivalent to the width of the products P.
  • the greater length of the outer strips 14b ensures that the end margins of all the strips gathered in the structure 16 are practically adjacent to each other, without any of them projecting from the structure 16.
  • the structure 16 (comprising four layers, i.e. - in this order - the outer strip 14b and the inner strip 14a of one of the channel-shaped parts, and then the inner strip 14a and the outer strip 14b of the other channel-shaped part) is then moved forward through a longitudinal welding group 102 intended to form the so- called longitudinal fin of a flowpack package.
  • the longitudinal fin is formed due to the juxtaposition and welding of two strips made of sheet material moved forward through such longitudinal welding group, in the example herein illustrated the strips made of sheet material adjacent into layers and passed through the group 102 are four.
  • the effect of the welding action performed by the welding group 102 is however influenced by the weldability/connectability characteristics of the sheet 10 illustrated in the introduction.
  • the four strips 14a, 14b moving forward inside the welding device 102 have - in sequence - this alternation (which can be ideally seen proceeding left to right and with reference to the point of observation of figure 5) of weldability characteristics: - a first strip 14b with an outer surface (with respect to the stratified structure 16) corresponding to the surface 10b of the sheet 10 and thus not weldable (as a matter of fact, the surface 10b is weldable along the strip 10c - and the strip 10c' , if present - which has/have given rise to the connection line 12) and an inner surface corresponding to the surface 10a of the sheet 10 and thus weldable;
  • a second strip 14a whose previously observed surface faces the first strip 14b, corresponds to the surface 10a of the sheet 10 and it is thus weldable, while the opposite surface corresponds to the surface 10b of the sheet 10 and is not weldable; a third strip 14a, having an outer surface facing the previously observed second strip corresponding to the surface 10b of the sheet 10 and thus not weldable and having an inner surface corresponding to the surface 10a of the sheet 10 and thus weldable; and lastly a fourth strip 14b, having an inner surface (with respect to the stratified structure 16) facing the previously observed third strip and corresponding to the surface 10a of the sheet 10 and thus weldable and an opposite surface (outer with respect to the stratified structure 16) which corresponds to the surface 10b of the sheet 10 and thus not weldable.
  • the net action of the welding tool 102 shall thus be that of connecting the strips whose opposite surfaces are weldable together, forming sealing lines.
  • the net action of the welding tool 102 is that of generating the welding:
  • the tool 102 does not determine the welding of the second strip with the third strip (i.e. the two "inner” strips 14a) given that mutually exposed on these strips are surfaces not weldable to each other.
  • the two fins 162 and 164 formed by the welding device 102 are thus independent with respect to each other and can be opened up apart from each other as clearly illustrated in figure 6.
  • the two matched tubular blanks thus formed can be moved forward towards the clamp units (alternating or rotating) usually present in a flowpack machine so as to form the transverse sealing lines 166, with the segmentation of the resulting line which leads to the formation of combined pairs of flowpack packages: the abovementioned transverse sealing and segmentation lines are produced according to entirely known criteria, such not to require a detailed description herein.
  • weldability/non-weldability mechanism can be attained by choosing constituent materials and/or a structure made of sheet material 10 different from that described previously. All this maintaining the general concept of providing in the packet of the elements moving forward through the welding group 102 (regardless of the principles regulating the operation of such group) a sequence of strips, made of sheet material, weldable in pairs to form the fins 162 and 164 - which however remain independent -not welded to each other.
  • weldability/non- weldability mechanism is suitable to be implemented also by applying an adhesive - hence for example by using sheet material 10 whose opposite surfaces 10a and 10b are both per se non-weldable but made weldable whenever necessary (lines 10c, 10c', strips 14a, 14b) - through local application of adhesive, for example by means of special applying nozzles.
  • the weldability between the two opposite surfaces does not absolutely require that the two surfaces be identical to each other. This occurs in the case of the example herein illustrated, where it is at least implicitly assumed that the surface 10a of the sheet 10 has uniform surface characteristics over the entire development thereof, therefore the mutually opposite surfaces of the strips 14a, 14b welded to each other in pairs to form the pins 162 and 164, are identical to each other and - for example - both covered with a heat-weldable material.
  • the weldability between the two surfaces may derive, for example, from the presence of a heat- weldable material or from the input of a heat-weldable material even only on one of two surfaces in question.
  • connection line 12 is made up of two flowpack packages connected by the welding line 12 (continuous or discontinuous) .
  • the products P were inserted after the line 12 had been made, hence they do not interfere with the making of the line 12 itself.
  • the resistance characteristics of the obtained connection of the line 12 are determinable in an accurate and precise manner (for example when producing sheet material 10, i.e.
  • the two sealing fins 162 and 164 which are diverging and thus facing opposite directions with respect to each other, for the rest maintain structural characteristics exactly identical to each of the single packages. Each of the packages is thus actually identical to the other.
  • the sealing lines 162 and 164 are arranged each in lateral position with respect to the tubular casing of the corresponding part of package (in that formed by means of an action performed simultaneously on all strips of the stratified structure 16) , ensures that the fins 162 and 164 are at an adjacent position with respect to each other and can perform - in an efficient and regular manner - a function of transferring the strip separation stress from the hands of the user towards the sealing line 12, which is interposed between them. Even leaving aside any other consideration, making such multiple package (with the longitudinal fins 162, 164 diverging from each other but located in close adjacency) coupling two single flowpack packages made separately would be rather difficult.
  • the consumer may seize the multiple package 20 and exert an action to separate the two packages by seizing the two sealing lines 166 (at one or the other end of the package) right where such transverse lines are extended at the longitudinal sealing lines forming the fins 162 and 164.
  • the seizing action is attained in a packaging zone where four layers of the packaging sheet material are adjacent and welded to each other.
  • this is a particularly strong zone where the action of the user may be exerted at best.
  • Figure 8 schematically represents a possible embodiment of a system for implementing the method illustrated in the sequence of figures 1 - 6.
  • reference B indicates the reel from which the sheet material 10 is unwound.
  • Reference 104 indicates the shaping station (or "former", of the per se known type) where the first U- shaping action referred to by figure 2 is performed. Downstream of the moulder in question there is the "choking" and welding station 100 whose action is represented in the same figure 3.
  • Reference 106 collectively indicates a further former where the overturned double-U shape (comprising two channel-shaped parts which are opened downwards in the illustrated example), represented in figure 4, is imparted to the sheet 10.
  • Reference 108 indicates a loading station where the products P are introduced (pushing them upwards) in the overturned double-U blank coming from the former 106.
  • Reference 110 indicates a so-called “plowshare” which opens out the longitudinal fins 162 and 164 apart from each other (see also figure 6) with the aim of supplying a welding and transverse cutting station 112, for example with alternating or rotating clamps, where the creation of the two transverse sealing lines 166 is performed with subsequent segmentation of the chain of multiple packages thus made .
  • the solution herein described allows making an entirely compact bi-pack package (or generally a multiple pack) , in that the single flowpack packages combined to each other acquire the shape of a package similar to the one that would be obtained by introducing the packages in question into a multipack package of the adherent type.
  • the solution herein described is adapted to be implemented with modifications suitably actuated in flowpack machines currently available at packaging systems level.

Abstract

Selon l'invention, un matériau de feuille d'emballage est mis en forme par formation d'au moins deux parties en forme de canal adjacentes, dans lesquelles sont insérés des produits respectifs (P). Avant l'insertion des produits (P), les parties en forme de canal adjacentes mentionnées ci-dessus sont reliées le long d'une ligne de liaison pouvant être défaite par déchirure (12), et également par découpe de la feuille (10) en une position intermédiaire (14) entre les parties en forme de canal elles–mêmes, de telle sorte que ces parties forment des parties distinctes reliées entre elles le long de la ligne de liaison (12). Les parties mentionnées ci-dessus sont en forme de tuyau, par la liaison des bandes distales respectives (14a, 14b) entre elles au niveau de lignes de scellement longitudinales respectives (162, 164), par la réalisation finale de lignes de scellement d'extrémité transversales (166). Un emballage multiple est par conséquent obtenu, lequel comporte une paire d'enceintes tubulaires contenant chacune au moins un produit respectif (P), reliées entre elles le long d'une ligne de liaison pouvant être défaite par déchirure (12) interposée entre les lignes de scellement longitudinales (162, 164), qui sont agencées de façon à s'ouvrir en s'éloignant les unes des autres.
