Description

-The present invention relates to a method to form a two piece package comprising a cover and a tray as well as a packaging obtained by this method.
-In particular, the present invention relates to a method to form a two piece package comprising a cover with a quadrangular shaped top with lateral edges or sides and a tray with a quadrangular shaped base with lateral edges or sides, in which, said cover and said tray are preferably joint together in a telescopic and/or extractable manner, in order to protect the product during its transportation and in order to immediately make it visible and ready for sale as it lies on the tray after the removal of the cover.

Background of the invention

-Currently, the known methods used to form two piece packages, as for example packages of the above mentioned type, have discontinuous and/or intermittent and/or multidirectional motions, with reference to the blank-cover and/or the blank-tray and/or the product translation, and consequently know methods require use of low operational speed with relative low productivity.
-In addition, the carrying out of said known methods include the use of automatic machines with large overall dimensions.
-Finally, said known methods, include operations that entail the application of force and/or of stress on the product to be packaged, with resulting damages to the product, and if said 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.

Purpose of the invention

-The purpose of the present invention is to solve the aforementioned problems.
-The invention, which is characterized by the claims, resolves the problem of creating a method to form a two piece package used to pack a product, in which said package comprises a cover with lateral edges placed above and around the top of the product and a tray with lateral edges placed beneath and around the bottom of the product, in which said method is characterized by the fact that the product is translated from upstream to downstream along a first rectilinear longitudinal translation path by means of the blank-tray placed beneath it in which said blank-tray acts as a transportation plane for said product; by the fact that the blank-cover is translated along a second translation path placed in a vertical upper-longitudinal alignment with respect to aforementioned first translation path, in which said second translation path comprises: >-a first segment extending inclined from upstream to downstream from upwards to downwards along which the blank-cover is arranged above the upper face of the product and >-a second segment extending straightway and parallel with respect to the first translation path along which the lateral edges of the blank-cover are formed around the top of the product; and by the fact that the blank-tray is translated along a third translation path extending longitudinally in a lower position-extension and in a vertical alignment with respect to said first and second translation paths, in which along said third translation path the blank-tray is translated in a straightway motion downstream with the product placed on the blank-tray and during said translation the lateral edges of the aforementioned blank-tray are formed around the bottom side of said product.
-Further characteristics and advantages of the present invention are rendered more evident by the detailed description that follows of some of the preferred forms of its practical realization, described here only as an example and without any restrictive intent, made with reference to the figures of the enclosed drawings, in which:

The Blanks

-With reference to figure 1, it illustrates a blank-cover comprising a first panel A-P1, a second panel A-P2 and a third panel A-P3, defined by means of creasing lines and arranged in succession with respect to an extension axes AY.
-With reference to figure 2, it illustrates a blank-cover A1 similar to the one represented by the figure 1, in which, the same above mentioned panels, here indicated as A1-P1, A1-P2 and A1-P3, are further equipped with closing flaps A1-P1sx, A1-P1 dx, A1-P2sx, A1-P2dx, A1-P3sx, A1-P3dx, arranged to the transversally opposed ends of each panel.
-With reference to figure 3, it illustrates a blank-tray B, comprising a first panel B-P1, a second panel B-P2, and a third panel B-P3, defined by means of creasing lines and arranged in succession with respect to an extension axes BY, in which said panels are provided with closing flaps B1-P1sx, B1-P1dx, B1-P2sx, B1-P2dx, B1-P3sx, B1-P3dx, arranged to the transversally opposed ends of each panel.

The Basic Method

-With reference to figures 4 and 4A, as well as to other figures, the basic method to form a two piece package comprises the following operative configuration: >-the translation of the product P along a first rectilinear longitudinal translation path P1 from upstream to downstream by means of the blank-tray B placed beneath it, in which said blank-tray acts as a transportation plane for said product P; >-the translation of the blank-cover, A/A1, along a second translation path P2 extending longitudinally and arranged above and in a vertical alignment with respect to aforementioned first translation path P1, in which said second translation path P2 comprises a first segment P2-ab extending inclined from upstream to downstream from upward to downwards along which the blank-cover A/A1 is translated and arranged above the upper face of the product P, and a second segment P2-bc, extending in a straightway parallel orientation with respect to the first translation path P1, along which the lateral edges of the blank-cover A/A1 are formed around the top of the product P; >-the translation of the blank-tray, B, along a third translation path P3 extending in a lower-longitudinal orientation and in a vertical alignment with respect to said first and second translation paths P1, P2, in which the aforementioned third translation path P3 comprises a segment P3-bd extending in a straightway parallel orientation with respect to the first translation path P1, along which the blank-tray B is translated and the lateral edges of said blank-tray B are formed around the bottom of the aforementioned product P.
-Again with reference to figures 4-4A, said third translation path P3 preferably comprises: >-a first segment P3-ab extending in an inclined orientation from upstream towards downstream from downwards to upwards along which the blank-tray is translated from upstream towards downstream from downwards to upwards and the product P moving along the first translation path is placed on the aforementioned blank-tray B; >-a second segment P3-bc, extending in a straightway parallel orientation with respect to the first and second translation paths P1 and P2 along which the blank-tray B is translated towards downstream in order to straightway translate along the first translation path P1 the product P and thus allow the formation of one or more lateral edges of the blank-cover A/A1 around the top side of the product P; and >-a third segment P3-cd, extending in a straightway parallel orientation with respect to the first and second translation paths P1, P2, along which the blank-tray B is translated straightway towards downstream in order to form the lateral edges of the blank-tray B around the bottom side of the product P, preferably by applying glue spots, 4Cdx, 4Csx, fig.4A, on the upper face of the closing flaps B-P2sx e B-P2dx before their folding upwards, or else, see fig. 5A, by applying glue spots, 5Csx e 5Cdx (the other glue spots are not visible) on the external faces of the closing flaps B-P1sx, B-P1dx, B-P3sx, B-P3dx, of the first B-P1 and of the third B-P3 panels of the blank-tray B.
-In particular, and always preferably, with reference to above quoted figures, the lower face of the product P is placed on the inferior panel B-P2 of the blank-tray B, and then, and in this manner, the product P is translated along the first translation path P1 by use of a pushing force F3 directly applied to the blank-tray B, in order to avoid any application of any force directly to the product for its downstream translation.
-Furthermore, it is preferable for the blank-cover, A/A1, to be translated along the second translation path P2 by applying of a pushing force, F2, directly to the blank-cover, A/A1, in which said force F2 is able to translate said blank-cover, A/A1, with substantially the same linear forward speed as the one set for the laying beneath product P.
-The blank-cover, A/A1, in all the above described forms, always comprise an upper panel, A-P2/A1-P2, used to cover the upper face of the product P and, in such context, depending on the type of the blank-cover and/or on the type of the product to be packaged, two operative configurations can be realised: >-a first operative configuration in which the aforementioned upper panel A-P2/A1-P2 is translated along the second segment P2-bc of the second translation path P2 in a suspended manner and to a closer upper level with respect to the top of the product P, thus avoiding any contact/friction between the aforementioned upper panel A-P2/A1-P2 and the top (upper face) of the product; or >-a second operative configuration, in which the same upper panel A-P2/A1-P2 is placed in contact with and/or supported on top of said product P.
-Also preferably, the product P would firstly be placed on the blank-tray B and, afterwards, while translating the product P towards downstream by the push-motion of the blank-tray B, the blank-cover A/A1 would be placed above and/or on the top of the product
