Definitions

  • the present description relates to packaging techniques and regards in particular techniques that enable production of multiple packages.
  • a sheet of wrapping material that is run off a reel is shaped according to a general channel-shaped conformation (usually open downwards) that enables insertion of the products in the package.
  • the free branches of the channel-shaped conformation are then brought to couple with one another so as to provide a longitudinal sealing line ("fin").
  • the tubular blank thus formed, with the products located inside it, then undergoes transverse sealing and cutting, to give rise to the individual wrappers.
  • the sealing heads cause a flattening in intermediate positions between the products, and in the flattened areas transverse sealing lines are formed in a region corresponding to which a cutting operation is performed such as to bring about separation of the individual wrappers.
  • multipacks packages of the type commonly referred to as "multipacks”. These are packages constituted by a number of individual flowpack wrappers grouped together and packaged in a flowpack of larger dimensions.
  • the process of production of said multipacks then entails repeating in cascaded fashion a number of packaging processes.
  • the individual flowpack wrappers that are contained inside it can get dispersed in an undesirable way.
  • a further drawback of the above technique is constituted by the considerable consumption of packaging material.
  • the aforesaid sealing lines can prove anything but easy to provide when the package already contains the products inside it.
  • the aforesaid sealing lines can end up opposing considerable resistance in regard to any tearing stress aimed at separating the individual packages from one another according to the modalities described previously. This fact can involve, for example, the need to subject the aforesaid sealing lines to treatments of pre-incision or dinking, which are aimed at facilitating tearing for the purpose of separation of the individual packages.
  • Said method envisages, in particular, using a modified flowpack packaging plant, where the wrapping material of which the package is made is shaped so as to form at least two channel-shaped parts, connected together along a connection line that extends parallel to their direction of extension and is set between the mutually facing walls of said parts. Subsequently, respective products are inserted in said channel-shaped parts, and then the latter are first closed to form a tube via respective longitudinal sealing lines, and finally closed at the end via respective transverse sealing lines.
  • Various embodiments of the corresponding package give rise to a multiple package (for example a double package), where the individual wrappers are in effect structurally identical to one another and/or can be separated from one another with an action of separation that is at the same time convenient and safe, preventing any risk of undesirable accidental opening of one of the wrappers that are separated.
  • Figure 1 represents an example of multiple package (designated by the reference 20) that can be obtained via the method forming the subject of the present description.
  • the multiple package 20 comprises a first flowpack wrapper 30, containing a first product P, formed by a first wrapping of sheet material that is closed to form a tube along a first longitudinal sealing line 162 (see Figure 11 ) and is provided with a first transverse sealing line (in technical jargon referred to as "closing bellows") 166 on both of its opposite ends.
  • a first flowpack wrapper 30 containing a first product P, formed by a first wrapping of sheet material that is closed to form a tube along a first longitudinal sealing line 162 (see Figure 11 ) and is provided with a first transverse sealing line (in technical jargon referred to as "closing bellows") 166 on both of its opposite ends.
  • the multiple package 20 further comprises a second flowpack wrapper 40 containing a second product P', formed by a second wrapping of sheet material that is closed to form a tube along a second longitudinal sealing line 164 (see Figure 11 ) and is provided with a second transverse sealing line (in technical jargon referred to as "closing bellows") 166' on both of its opposite ends.
  • a second flowpack wrapper 40 containing a second product P', formed by a second wrapping of sheet material that is closed to form a tube along a second longitudinal sealing line 164 (see Figure 11 ) and is provided with a second transverse sealing line (in technical jargon referred to as "closing bellows") 166' on both of its opposite ends.
  • the first and second wrappers are set alongside one another in a direction transverse to the aforesaid first and second sealing lines and are connected together, at one or both of their opposite ends, in an area corresponding to the aforesaid first and second transverse sealing lines (or closing bellows).
  • said connection between the transverse sealing lines is of a tear-separable type.
  • the sealing lines mentioned herein can be of any type suitable for the application in question.
  • said sealing lines can be obtained via heat-sealing, ultrasound sealing, or else gluing.
  • the transverse sealing lines will be called by the term “closing bellows" commonly used, without thereby wishing to refer to any of their specific embodiments.
  • the method described herein envisages, in general, forming a first tubular blank of the first wrapper, containing the first product, and a second tubular blank of the second wrapper, separate and distinct from the first blank and containing the second product, and setting the aforesaid first and second blanks alongside one another, and moreover making, on one or both of the opposite end portions of the aforesaid first and second blanks, a transverse sealing line that traverses both of the corresponding portions of the aforesaid first and second blanks in said condition where they are set alongside one another, and is designed to define the aforesaid first and second bellows, respectively of the aforesaid first and second wrappers, and at the same time to determine a tear-separable connection between said first and second bellows.
  • the aforesaid transverse sealing line (which traverses both of the corresponding portions of the aforesaid first and second blanks) constitutes a common or shared sealing line between the two wrappers that make up the multiple package, in the sense that said line is designed to define both of the aforesaid first and second bellows (or first and second sealing lines) of said wrappers.
  • said line can be easily "torn” or “split" in the aforesaid first and second bellows (or first and second sealing lines) for separating the two wrappers of the multiple package.
  • said common sealing line constitutes an adhesion line; namely, where it is provided, parts of wrapping material that can be connected together are made effectively to adhere to one another (in this connection, the reader is referred to the ensuing description, where the possible modalities according to which respective parts of wrapping material can be rendered connectable to one another are explained); in the method described herein said line is such as to traverse both of the corresponding end portions of the aforesaid first and second blanks for determining the aforesaid first and second sealing lines and at the same time the aforesaid tear-separable connection between said sealing lines. As will be seen in what follows, preferably said line extends continuously, traversing completely the corresponding ends of the aforesaid first and second blanks.
  • the aluminium (or plastic) material is not instead coated other than in areas 10c (which may mate with homologous areas 10c' situated in a position specularly symmetrical to the areas 10c with respect to the folding direction, as will be described more fully in what follows), where a heat-sealable (or ultrasound sealable) plastic material, such as polyethylene, is applied.
  • the areas 10c and 10c' illustrated in Figure 2 are, on one, front (with respect to the direction of A), half thereof (defined by an ideal cutting line orthogonal to the direction A), designed for the production of a first multiple package and, on the other, rear, half, for the production of a second multiple package (subsequent to the first package with respect to the direction of advance A).
  • the sheet 10 is constituted by non-heat-sealable plastic material that on the surface 10a is treated with a heat-sealing lacquer or else laminated with a sealing layer, whereas instead on the surface 10b, only in the areas 10c (and, if present, the areas 10c') it is rendered heat-sealable by application of heat-sealing lacquer.
  • the surface 10a can be connected to a homologous surface
  • the surface 10b resists the action of connection with a homologous surface, except in the areas 10c (and the areas 10c', if present).
  • the method forming the subject of the present description can envisage the steps of:
  • FIGS. 4 to 11 illustrate a preferred embodiment of such an apparatus.
  • Said apparatus further comprises a line for conveying the products to be packaged, comprising in the specific case two conveyor belts T, T' (or else one conveyor belt divided into two product conveying paths) that run parallel to one another in the direction of advance A.
  • said direction A corresponds to the direction of advance both of the sheet of wrapping material 10 and of the products P and P'.
  • Said conveyor belts are controlled in a co-ordinated way for conveying the products P, P' in a condition where they are set alongside one another.
  • the apparatus further comprises a shaping station 120 that is traversed by the aforesaid conveying and feed lines.
  • the line for feeding the wrapping sheet enters the shaping station with a descending branch of the wrapping sheet, which in said station is then brought back substantially parallel to the direction A referred to above.
  • the inclination of the aforesaid branch, with respect to the line for conveying the products facilitates intervention of the means - which will be described in what follows - of said station that have the function of pulling said sheet of wrapping material against said products.
  • said station comprises first means designed to pull by the side flaps the aforesaid sheet of wrapping material against the products P, P' on the conveyor belts, and second means designed to make a depression in a central portion of the wrapping material set between the two rows of products.
  • said shaping station comprises two side laminas 90 and one central lamina 92 that extend, starting from one and the same position, parallel to and set alongside one another in the direction A, in an area corresponding to the two conveyor belts T and T'.
  • the central lamina 92 extends slightly further forward than said conveyor belts and, immediately downstream of said lamina, said shaping station envisages two or more pairs of opposed rollers 102, which, with the aid of the two side laminas 90, have the function of pulling by the side flaps the wrapping material against the products P and P'.
  • rollers 102 The action of the rollers 102 will be described in the detail in what follows; in any case, it should here be pointed out that the function referred to above - of pulling the wrapping material by the flaps - is in itself carried out just by the rollers 102, whilst the side laminas 90 act simply as guide for said flaps.
  • the central lamina 92 has, instead, the function of forming a depression in the central portion of the wrapping sheet that is set between the two rows of products.
  • the side laminas 90 and the central lamina 92 each have, in an area corresponding to their end facing in the direction opposite to the flow of the products and of the wrapping material, an inclined edge designed to constitute a guide for the branch of the wrapping material entering the shaping station 120.
  • Said laminas have, moreover, at said ends, respective wheels 94 designed to favour sliding of the wrapping material and prevent a sticking of said laminas in said material, which could cause tearing of the material itself.
  • the co-ordinated action between the means referred to above has the function of shaping the wrapping sheet according to a form having the aforesaid channel-shaped parts set alongside one another, with the products P and P', respectively, inside them.
  • the central lamina has, in a position downstream of the two side laminas, and in a region once again corresponding to the two conveyor belts, a blade 96 designed to separate the distal flaps 14a, in such a way that said channel-shaped parts are separate and distinct from one another.
  • the free flaps of the two channel-shaped parts (designated by 14a, in the case of the free flaps of the two inner branches, which are shorter and set up against one another, and by 14b, in the case of the free flaps of the two outer branches, which are longer and opposite to one another) are set up against each other so as to form a layered structure designated as a whole by 16.
  • the outer flaps 14b are longer than the inner flaps 14a by a length approximately equal to the width of the products P. In this way, when the various flaps are gathered to form the structure 16, located in position substantially half-way between the products P, the greater length of the outer flaps 14b causes the end margins of all the flaps gathered in the structure 16 to be set practically alongside one another, without any of them projecting from the structure 16.
  • the structure 16 (comprising four layers, i.e., - in order - the outer flap 14b and the inner flap 14a of one of the channel-shaped parts, and then the inner flap 14a and the outer flap 14b of the other channel-shaped part) is then made to advance through the opposed rollers 102.
  • the opposed rollers 102 also constitute a longitudinal-sealing assembly that is to form, in the way described in what follows, the so-called longitudinal fin of a flowpack wrapper. It is, however, clear that, according to alternative embodiments of the apparatus, there may be envisaged a longitudinal-sealing assembly distinct from the rollers 102, and set downstream thereof.
  • the longitudinal fin is formed as a result of juxtaposition and sealing of two flaps of sheet material fed through one said longitudinal-sealing assembly
  • the flaps of sheet material that are set on top of one another in layers and passed through the sealing assembly 102 are four in number.
  • the effect of the sealing action obtained by the sealing assembly 102 is, however, conditioned by the characteristics of sealability/connectability of the sheet 10 illustrated at the start.
  • the four flaps 14a, 14b that advance within the sealing device 102 have in sequence the following alternation of characteristics of sealability (which can be ideally viewed proceeding from left to right and with reference to the point of observation of Figure 5 ):
  • the net action of the sealing tool 102 will be hence that of connecting together, with formation of sealing lines, the flaps the opposite surfaces of which are sealable.
  • the net action of the sealing tool 102 is to produce sealing of:
  • the tool 102 does not instead bring about sealing of the second flap with the third flap (i.e., of the two inner flaps 14b) since these flaps expose to one another surfaces that cannot be sealed to one another.
  • the two fins 162 and 164 formed by the sealing device 102 are thus independent of one another and can be separated away from one another, as is clearly illustrated in Figure 9 , for example via a so-called "plowshare" (not illustrated in the figures).
  • FIG. 7 is a schematic illustration of the mutual configuration of the wrapping material and of the products that are obtained with the apparatus of Figure 11 , in the area set between the rollers 102 and the transverse cutting and sealing station 122 (which will be described more fully hereinafter).
  • said configuration presents two distinct tubular blanks 30', 40' - closed in a tube-like form along respective longitudinal sealing lines and each containing a respective product - that occupy positions set alongside one another in a direction transverse to their respective longitudinal sealing lines.
  • the two tubular blanks are represented as being at a given distance from one another.
  • one of the two blanks is provided with a connection area 10c, on each of its opposite ends, in a position laterally shifted so as to give out onto a respective corresponding end of the other blank. If, as illustrated in said figure, also the areas 10c' are present, they are located on the other blank, in positions specularly symmetrical to the areas 10c - with respect to an ideal plane parallel to the axial direction of the two tubular blanks and set between these - and facing these.
  • the two tubular blanks thus formed are then made to advance towards the transverse-sealing station 122, comprising jaw units 112 (with reciprocating or rotary motion) designed to form on each tubular blank the end closing bellows of the package.
  • a transverse sealing line 200 that traverses both of the corresponding end portions of the tubular blanks and superposes the areas 10c on the areas 10c', if present, or else on corresponding portions of the blank opposite to the one in which said areas 10c are provided.
  • Said sealing line is consequently designed to create the respective closing bellows 166, 166' of said blanks and at the same time a tear-separable connection between said bellows.
  • said jaws create the respective end bellows 166, 166' of the two blanks, which, from what has been described above, will be connected to one another in the areas 10c (and 10c', if present).
  • the sealability between two opposite surfaces does not require in an absolute way that the two surfaces be identical to one another. This happens in the case of the example illustrated herein, where it has been at least implicitly assumed that the surface 10a of the sheet 10 will have uniform surface characteristics throughout its development, so that the mutually facing surfaces of the flaps 14a, 14b sealed to one another in pairs to form the fins 162 and 164, are the same as one another and - for example -both coated with a heat-sealable material.
  • the sealability between two surfaces can in fact derive, for example, from the presence of a heat-sealable material or from application of an adhesive material also on just one of the two surfaces in question. This applies of course also in relation to the connection areas 10c and 10c': in this regard it has in fact been pointed out a number of times that the presence of the areas 10c' is altogether optional.
  • the final package thus obtained is constituted by two flowpack wrappers set alongside one another in a direction transverse to the longitudinal sealing lines of the two wrappers, and connected together at the respective end bellows.
  • the characteristics of resistance of the connection made between the bellows can be determined exactly and precisely (for example, during production of the sheet material 10, i.e., during creation of the areas 10c - and of the homologous areas 10c', if present), preventing said connection, on the one hand, from being too weak, with the risk of an undesirable separation of the wrappers and, on the other hand, from offering an excessively high resistance to tear, exposing the consumer to the risk of tearing in an undesirable way one of the wrappers that are for the moment not to be opened.
  • connection between the two packages at their bellows enables concentration, on these, of the stresses that are generated when the user separates said wrappers, and hence prevents, during their separation, any risk of tearing of said wrappers, since said bellows are formed by as many as two layers sealed to one another (along the transverse sealing line 200) and are consequently extremely strong.
  • said bellows are formed by as many as two layers sealed to one another (along the transverse sealing line 200) and are consequently extremely strong.
  • the products contained therein are not subjected to any stress, and there is consequently no risk of them getting broken as a result of the forces exerted to separate the two wrappers.
  • the two or even more tubular blanks can be formed separately according to the conventional modalities of a normal flowpack packaging line, and, then be arranged alongside one another in the configuration described above, in order to be able then to form on their corresponding end portions the aforesaid transverse sealing line, designed to determine the respective closing bellows of said blanks and at the same time a tear-separable connection between said bellows.
  • said blanks set alongside one another must be either set in contact with one another, or else their mutual distance, if not zero, must be in any case such that, as described previously, when their end portions are squeezed to form the respective closing bellows, these flatten out and expand laterally until they overlap the corresponding portions of the blank or blanks set alongside, and enable in this way, for what has been described previously, a mutual connection between the overlapping parts.
  • said parts for connection of the end portions may be connectable to one another either as already the sheet material that is run off the reel is sealable in said parts, for example, because in the production of the reel these have been coated with heat-sealing lacquer, or because in the process of production of the multiple package they have been rendered connectable and/or sealable via application of adhesive and/or heat-sealing material.
  • the solution described herein enables a bi-pack package (or in general a multiple package) to be produced that is altogether compact, in the sense that the individual flowpack wrappers paired with one another assume the conformation of a package resembling the one that would be obtained by inserting the wrappers in question in a multipack package of an adherent type.
