[0001] -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.
[0002] -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
[0003] -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.
[0004] -In addition, the carrying out of said known methods include the use of automatic
machines with large overall dimensions.
[0005] -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
[0006] -The purpose of the present invention is to solve the aforementioned problems.
[0007] -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.
[0008] -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

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.
[0010] -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.
[0011] -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
[0012] -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.
[0013] -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.
[0014] -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.
[0015] -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.
[0016] -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.
[0017] -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

panel A-P2 is translated and arranged in vertically alignment above the top face of
the product P and, along the second segment P2-bc of the second translation path P2,
the blank-cover A is translated downstream maintaining the vertical alignment between

path P2, the blank-cover A is translated downstream maintaining the vertical alignment
