Description

- The present invention relates to a method to form a cover on top of a product, as also to form a two-piece package including said cover and a tray.
- In particular, this invention relates to a method to form a cover shaped like an inverted "U" on top of a product, including a front, an upper and a back panel, or a cover that includes the aforementioned three panels and furthermore some closing flaps, in order to form a quadrangular cover with an upper panel and four perimetrical edges joined together.
- Furthermore, the present invention also relates to a method to form a two-piece package, comprising the aforementioned three-panel cover or said quadrangular cover on top of the product, and a tray placed around the base of the product, in which said tray can comprise a front panel, a back panel and an inferior panel, or the aforementioned three panels and closing flaps, in order to form a quadrangular tray with a inferior panel and four perimetrical edges joined together, in which, if desired, said cover and said tray are joined together but easily separable.

Background of the invention

- Currently, the known methods to form a cover on top of a product are arduous, inaccurate and require multiple applications of adhesive, and consequently result in less operational speed and relative lack of productivity.
- In addition, these methods include operations that entail the application of force and/or of stress on the being packaged product, with resulting damages to the product and if the product consists in a group of bottles, this stress and/or collision and/or friction between the bottles and the blank-cover may cause undesired overturning of the aforementioned bottles and/or an undesired change in the required form of the batch.
Finally, these methods are arduous and slow if used to form two-piece packages, as for example packages including the above said cover and a tray around the base of the product; in which said two pieces, if desired, can easily be joined together and separated, with the purpose of transporting the product within a closed package and with the purpose of making the product visible through an easy and rapid removal of the top cover.
- A known method is described in WO 01/04017 A1 according to which, however, the forward movement of the product is used to apply a force onto the blank-cover which has the drawback that the product may be damaged or get into disorder if the product is made up of a group of bottles or the like. In this known method, the blank is positioned vertically downwards in front of the product and in a coplanar configuration of its panels.

Purpose of the invention

-The purpose of this invention is to resolve the aforementioned problems.
-The invention, which is characterized by claim 1, resolves the problem of creating a method to form a cover on top of a product having the features of said claim. Further characteristics are mentioned in the dependent claims.

1 ^st Realization - Basic Method to form a cover shaped like an inverted "U".

-With respect to Figure 1 , it illustrates a first realization of the method subject of the present invention, hereby defined as basic method, which, as will be better understood below, can be used to form covers of different types and/or two-piece packages comprising said covers and a tray.
-In this first realization, the method is act to form a cover like an inverted "U" on top of a product P, in which said cover is formed by a blank-cover A that comprises, with respect to a longitudinal axis A-Y, at least a back panel A-PP, an upper panel A-PS and a front panel A-PA that are separated by means of transversal creases A-10 and A-20.
-In the illustrated example, the products P, hereby illustrated as single lots of bottles, are translated from upstream to downstream along a first path P1 of products translation, for example driven by a translation force F1 acting directly on product P.
-In particular, according to this basic method, following operations are performed: a) -the blank-cover A is placed in a folded configuration in the first zone Z1, upstream from the first path P1, above of and in front of the product P, with its back A-PP and upper A-PS panels horizontally coplanar placed above the upper side of the product P and with front panel A-PA vertically placed in front of the front side of the product P; b)-the blank-cover A is translated in this folded configuration from the first zone, Z1, downstream along the first path P1, as soon as the front side of the product P comes against and/or near the front panel A-PA of the blank A; c)-the back panel A-PP of the blank-cover A is folded against the back side of the product P while the product P and the blank-cover A are translated downstream along the first path P1.
-With reference to operation a), preferably, the back panel A-PP and the upper panel A-PS are translated and placed at a level vertically slightly spaced with respect to the top of the product, thus obtaining an operative configuration in which the blank-cover A is positioned, stopped, suspended, transversally centred and vertically aligned above of and in front of the product P in motion, in such way that said product P can freely advance downstream against the front panel A-PA of this stationary blank-cover A without any interference between the top of the product P and the upper and back panels A-PS and A-PP, thus avoiding any possible overtumings of the bottles and/or avoiding any modifications in the shape of the lot.
-With reference to operation b), preferably, the blank-cover A is translated downstream along the first path P1 as soon as the front side of product P comes against the front panel A-PA, or little before the front side of the product P comes against the front panel A-PA, thus avoiding and/or limiting the impact between the front side of the product P and the front panel A-PA of the blank-cover A for any of the aforementioned reasons.
-Also with reference to operation b), it is preferable to translate the same blank-cover A from said zone Z1 along a path with a high-low, upstreamdownstream longitudinally orientation, in order to delicately place the suspended blank-cover A on top of the product P; alternatively, it is also possible to let the blank-cover A fall on top of the product P as soon as (or little before) the front side of the product P makes contact with the front panel A-PA.
However, in both cases, the set obtained by P+A and placed downstream of the zone Z1 will comprise a product P partially covered by a blank-cover A correctly placed and centered, namely with the upper panel A-PS lying correctly on top of the upper side of the product P and with the front panel A-PA correctly placed against the front side of the product P.
-Also with reference to the aforementioned basic method, it is preferable to translate the blank-cover A along the first path P1 with substantially the same linear forward speed with respect to the linear forward speed set for the product P, in order to limit and/or to avoid any relative movements between the blank-cover A and the product P.
-Furthermore, in order to translate the product P and the blank-cover A downstream, it is preferable to apply a first force F1 directly on the product P and a second force F2 directly on the blank-cover A; in which said second force F2 will preferably be applied at first along the back edge of the back panel A-PP during the second operation b) and, after and/or during the folding towards the bottom of said back panel A-PP, i.e. third operation c), along the back edge of the upper panel A-PS.
-Also with respect to Figure 1, preferably, in order to position the blank-cover A in the zone Z1, said blank-cover A is translated in a folded configuration along a first segment placed downstream of a second blank-translation path P2 in which said second path P2 will preferably be transversally aligned with respect to the first path P1.
-Furthermore, optionally, this second path P2 can also include a second segment upstream aligned, along which the blank-cover A would be folded from its original flat configuration to its folded configuration.
-Also with respect to Figure 1, in order to obtain a continuous flow of products fit out with a cover, a continuous flow of product P is translated, preferably in a continuous motion, in a single succession and spaced to eachother along the first path P1 and, at the same time, a blank-cover A in a folded configuration can be inserted and placed in said zone Z1 in phase correlation and in a single succession, using for this insertion/positioning operation the time interval between two products P positioned in an immediate succession.

2 ^nd Realization - Method to form a quadrangular cover with lateral edges.

-With reference to Figure 1A, it illustrates a second form of realization of the aforementioned basic method here used to form a quadrangular cover with lateral edges on top of the product P.
-In this second form of realization, the blank-cover, here indicated as A1, besides the aforementioned front, upper and back panels, A-PA, A-PS, A-PP, also includes closing flaps determined by means of creases and, more particularly, front closing flaps A-PAsx and A-PAdx placed on the opposite transversal ends of the front panel A-PA, upper closing flaps, A-PSsx, A-PSdx, placed on the opposite transversal ends of the upper panel A-PS, and back closing flaps, A-PPsx, A-PPdx, placed on the opposite transversal ends of the back panel A-PP.
-In this case, and in a substantially similar-identical manner as the previous one, following operations are performed: a)-a blank-cover A1 is placed in the first zone Z1 upstream from the first path P1, in a folded configuration, above and in front of the product P, with its back A-PP and upper A-PS panels horizontally coplanar placed above the upper side of product P and with the front panel A-PA vertically placed in front of the front side of product P; b)-the blank-cover A1 is translated in the aforementioned folded configuration from the first zone, Z1, downstream along the first path P1, as soon as the front side of the product P comes against the front panel A-PA of the blank-cover A; afterwards, the other operations are executed in order to form the cover, i.e.: c1)-the closing flaps A-PAsx, A-PAdx, of the front panel A-PA of the blank-cover A1 are folded inwards against the product P; c2)-the closing flaps A-PPsx, A-PPdx, of the back panel A-PP of the blank-cover A1 are folded towards the bottom; c3)-the back panel A-PP of the blank-cover A1 is folded downwards and against the product P; c4)-the closing flaps A-PSsx, A-PSdx, of the upper panel A-PS of the blank-cover A1 are folded downwards and against the closing flaps A-PAsx, A-PPsx, A-PAdx, A-PPdx of the front panel A-PA and of the back panel A-PP.
-With reference to the aforementioned method, please note that operations a) and b) are identical with respect to the operations a) and b) of the first realization, and that the operation c3) corresponds to the operation c) of the first realization.
-Furthermore, it is preferable to join the closing flaps A-PSsx and A-PSdx of the upper panel A-PS with and above the closing flaps A-PAsx, A-PAdx, A-PPsx, A-PPdx, of the front panel A-PA and of the back panel A-PP; in which in order to obtain said joints adhesive is placed on the internal-lower side of the upper closing flaps, A-PSsx and A-PSdx, of the upper panel A-PS and/or on the external side of the front closing flaps, A-PAsx and A-PAdx, of the front panel A-PA, and/or on the external side of the back closing flaps, A-PPsx and A-PPdx, of the back panel A-PP, in which also preferably, said adhesive is applied during the translation of the blank-cover A along the first translation path P1.
-In this way, as a consequence of the operations described above, a quadrangular cover will be formed on top of the product P, which will have an upper panel PS and four vertical edges on the four sides, in which said upper panel PS and the four vertical edges are joined together.

3 ^rd Realization - Method to form a quadrangular cover with lateral edges.

-With reference to Figure 2, it illustrates a third realization of the basic method, in which the front closing flaps, A-PAsx, A-PAdx, the upper closing flaps, A-PSsx, A-PSdx, and the back closing flaps, A-PPsx, A-PPdx, are folded by means of a different operative method.
-In this case, the method is the same as described in the second realisation for operations a) and b) and, afterwards the following operations are performed: c1)-the closing flaps A-PSsx, A-PPdx, of the upper panel A-PS of the blank-cover A1 are folded downwards and against the product P; c2)-the closing flaps A-PPsx, A-PPdx, of the back panel A-PP of the blank-cover A1 are folded downwards; c3)-the back panel A-PP of the blank-cover A1 is folded downwards and against the product P, with closing flaps A-PPsx, A-PPdx, of the back panel A-PP placed over the closing flaps A-PSsx, A-PSdx of the upper panel A-PS.; c4)-the closing flaps A-PAsx, A-PAdx, of the front panel A-PA of the blank-cover A1 are folded inwards over the closing flaps A-PSsx, A-PSdx, of the upper panel A-PS.

Common characteristics between the fourth and the fifth realization

-With reference to the fourth and the fifth realization, it is optionally possible to join together the cover with respect to the tray, preferably by unions that should have a calibrated resistance for an easy detachment in order to facilitate the removal of the cover, so that the product lot could be exhibited on its tray at the points of sale and also easily removed from the tray in order to be bought.
-In this context, it is preferable for the front panel A-PA to be joined to the front panel B-PA, by applying the adhesive C1, C2, on the external side of the front panel A-PA and/or on the internal side of the front panel B-PA, in those zones where these two sides will be joined together and where the adhesive will preferably be applied on during the translation of the blanks along said first P1 or second P2 translation paths.
-Furthermore, and in the same manner, it is also possible to join together the back panel A-PP with the back panel B-PP, by using the adhesive C3, C4, applied on the external side of the back panel A-PP and/or on the internal side of the back panel B-PP, preferably also along the first or second translation path P1, P2.
-By means of these unions, it is for example sufficient to insert a hand from up to down between the two joint panels in order to obtain a detachment and therefore an immediate removal of the cover.
