[0001] The present invention relates to a package for medicinal, pharmaceutical and similar
products, particularly of the pill type, and to the associated method and apparatus
for manufacturing and filling it.
[0002] Various kinds of container for packaging medicinal products in general, and pills
in particular, are known; such containers generally use blisters packages constituted
by a film, which is thermoformed so as to provide a sort of shell that has a plurality
of receptacles for containing respective products, and by a pierceable aluminum covering
film, which is associated with the preceding film so as to close said receptacles.
[0003] The product contained in each receptacle is removed by applying pressure to the convex
face of said receptacle, so as to press the product against the covering film until
it is pierced, causing said product to exit.
[0004] Blister packages generally have a flat shape and are inserted, together with the
information leaflet related to the medicinal products contained therein, in box-like
protective enclosures, usually made of die-cut cardboard, before they are sent to
commercial distribution.
[0005] These enclosures can be opened at one or more faces constituted by folding tabs.
[0006] However, the use of said enclosures is sometimes awkward, since after opening them,
the blister is not directly accessible but has to be extracted from the corresponding
enclosure.
[0007] This drawback is even more inconvenient if one considers that a plurality of blisters
are usually inserted in the enclosure together with the corresponding information
leaflet, and therefore when one turns upside down the open enclosure so as to cause
the exit of the intended blister, the remaining contents are also expelled from it.
[0008] Moreover, these enclosures may become damaged over time, no longer allowing to close
and protect the blisters contained therein.
[0009] Not least, the information leaflets attached to medicinal products, which are folded
and stored loosely inside said enclosures, may become damaged over time, making it
impossible to retrieve the information that they contain, or in an extreme case may
be lost.
[0010] These drawbacks are at least partially overcome by a second known type of package
of medicinal products, which provides a sort of book-like case provided with three
pages that can be folded onto each other, one or more blisters of the type described
above being arranged at one of the pages.
[0011] These cases are obtained from two superimposed cardboard sheets, which are folded
appropriately so as to form the pages, at one of which at least one through opening
is provided; a corresponding blister is arranged inside the opening, and the perimeter
of the blister is retained between the two cardboard sheets.
[0012] The information traditionally contained in the leaflet can be provided directly on
the pages of the case, so as to make it always accessible and available to the user.
[0013] Even these known cases, however, are not free from drawbacks, including the fact
that in order to maintain the closed configuration they must be inserted in tubular
enclosures, i.e., be provided with other additional closure devices suitable to lock
the pages so that they are folded together; these devices are not practical and quick
to use for the user and do not ensure safe closure and protection of the products
packaged inside them.
[0014] It should be noted that the additional closure devices are for example of the type
of sleeves, which need to be removed and then positioned every time the product is
taken from the package, or of adhesive elements, which are applied to the cases but
do not ensure a sufficiently durable seal.
[0015] Another limitation of these types of package is that their manufacturing cycle is
rather complicated, since it requires managing various auxiliary materials and feeding
them to the corresponding manufacturing line, which accordingly has a rather articulated
and complex structure.
[0016] Finally, the various types of package that are currently known use blisters that
allow exclusively to remove individual products, and therefore if the user needs,
for example, to take a plurality of pills through the day he/she is forced to take
the entire package with him/her, with the risk of damaging it and of damaging the
products contained therein that are not used immediately.
[0017] As an alternative, it is possible to cut a portion of the blister by means of conventional
cutting tools, such as scissors or the like, which are of course not always easily
available and the use of which can injure the user.
[0018] The aim of the present invention is to eliminate the drawbacks mentioned above of
the background art, by providing a package for medicinal, pharmaceutical and similar
products, and a corresponding method and apparatus for manufacturing and filling,
which is practical to use for the end user, is easy to handle during use, and allows
to protect appropriately the products contained therein until they are depleted.
[0019] Within this aim, an object of the present invention is to provide a package that
allows the information related to the method of use or other information related to
the products contained therein to be always available.
[0020] Another object of the present invention is to provide a package that is visually
pleasant for the user and can be carried easily in bags, handbags and the like.
[0021] Another object of the present invention is to provide a package that is simple, relatively
easy to provide in practice, safe in use, effective in operation, and has a relatively
low cost.
[0022] This aim and these and other objects that will become better apparent hereinafter
are achieved by the present package for medicinal, pharmaceutical and similar products,
comprising a shell provided with at least two wings, provided with respective receptacles
for containing corresponding products, and a separation rib, which is interposed between
said wings, a layer for closing said receptacles, which is associated with said shell,
each wing being articulated about a corresponding side of the separation rib between
an open configuration, in which said wings are mutually spaced, and a closed configuration,
in which they are arranged so that their respective inner faces are in mutual contact
and the receptacles protrude between said faces, and means for closing said wings
by pressing, said means being associated with said shell, characterized in that the
receptacles of each wing are offset with respect to the receptacles of the other one
of said wings and are arranged side by side at a distance that is at least equal to
their transverse dimension, part of the receptacles of each wing being able, in the
closed configuration, to be accommodated between two adjacent receptacles of the other
one of said wings, and in that said closure means comprise at least one ridge that
protrudes laterally from at least one receptacle.
[0023] This aim and these and other objects are also achieved by a method for manufacturing
and filling the package according to the invention, characterized in that it comprises:
a step for thermoforming a strip of thermoformable film, during which a plurality
of said shells provided with corresponding closure means is obtained, said shells
being distributed along the strip and being arranged so that their respective receptacles
are open upward; a step for filling said receptacles with corresponding products;
a step for heat-sealing a pierceable protective film on said shells in order to close
said receptacles; a step for pre-cutting each shell, in which at least said folding
lines are provided; and a step for cutting and separating each shell and the corresponding
closure layer, respectively, from said strip and from said film made of pierceable
material so as to obtain a substantially flat package.
[0024] This aim and these and other objects are further achieved by an apparatus for manufacturing
and filling the package according to the invention, characterized in that it comprises
a unit for discontinuously feeding at least one strip of thermoformable film, along
which there are: a station for thermoforming said strip, which comprises a mold constituted
by two mold parts, at least one of which can move toward and away from the other,
in order to obtain a plurality of said shells, each provided with corresponding closure
means, distributed on said strip along at least one row and arranged so that the respective
receptacles are open upward; a station for inserting corresponding products in said
receptacles; a station for feeding and heat-sealing a protective and pierceable film
on said thermoformed strip in order to close said receptacles so as to obtain a plurality
of blisters in a flat configuration, distributed along said strip; a station for pre-cutting
each flat blister along predefined lines so as to obtain at least said folding lines;
and a station for cutting and separating each flat blister from said strip.
[0025] Further characteristics and advantages of the present invention will become better
apparent from the following detailed description of a preferred but not exclusive
embodiment of a package for medicinal, pharmaceutical and similar products, particularly
of the pill type, and of the corresponding method and apparatus for manufacturing

[0026] With reference to the figures, the reference numeral 1 generally designates a package
for medicinal, pharmaceutical and similar products, particularly of the pill type
or the like.
[0027] The package 1 comprises a shell 2 provided with at least two quadrangular wings 3
and with a rib 4 for separating the wings; each wing 3 is provided with a plurality
of receptacles 5 for containing corresponding products, of the pill type or the like,
and is articulated about a corresponding side of the rib 4 that is formed by a corresponding
folding line 6.
[0028] Accordingly, the wings 3 can assume an open configuration, in which they are mutually
spaced, and a closed configuration, in which they are arranged so that their respective
internal faces 3a are in mutual contact and the receptacles 5 protrude between the
faces.
[0029] The shell 2 is obtained by thermoforming a film made of thermoformable material,
such as PET or PVC.
[0030] In the illustrated embodiment, the receptacles 5 have an elongated shape and are
arranged transversely with respect to the rib 4.
[0031] Conveniently, the receptacles 5 of each wing 3 are offset with respect to the receptacles
5 of the other wing 3 and are arranged side by side, at a distance that is at least
equal to their transverse dimension; in the closed configuration, some of the receptacles
5 of each wing 3 can be accommodated between two adjacent receptacles 5 of the other
wing 3.
[0032] In a possible embodiment, not shown in the figures, such distance may be on the same
order of magnitude as the transverse dimension of the receptacles 5, or better still
slightly smaller than said dimension, so that in the closed configuration some of
the receptacles 5 of each wing 3 can be accommodated with interference between two
adjacent receptacles 5 of the other wing 3, making it easier to maintain the closed
configuration.
[0033] Further, the package 1 comprises a layer 7 for closing the receptacles 5, which is
associated with the shell 2 by heat-sealing or other methods, so as to cover it at
least at the wings 3.
[0034] The layer 7 is made of flexible and pierceable material, such as for example aluminum,
and has a low thickness.
[0035] Advantageously, the package 1 has means 8 for closing the wings 3 by pressing; such
means are associated with the shell 2 and are adapted to keep said wings in the closed
configuration.
[0036] The closure means 8 and the wings 3 are preferably formed monolithically with respect
to each other.
[0037] The closure means 8 comprise a tab 9, which protrudes from the inner face 3 a of
one of the wings 3, and a corresponding recess 10 formed at the inner face 3a of the
other wing 3; the tab 9 can be inserted with interference in the recess.
[0038] During use, the user has to gently pull the closed wings so as to disengage the tab
9 from the recess 10 and open the wings; to close the wings 3, it is instead necessary
to apply a slight pressure to them so as to force the tab 9 into the recess 10.
[0039] Each wing 3 has a profile 11 that protrudes from the corresponding internal face
3a and lies along the peripheral portion of said wing.
[0040] The tab 9 and the recess 10 are formed at the respective profiles 11, proximate to
the centerline of the portions of said profiles, and substantially parallel to the
folding line 6.
[0041] The profiles 11 are wider at the tab 9 and at the recess 10.
[0042] The recess 10 is constituted by a slot formed in the corresponding profile.
[0043] Advantageously, the closure means 8 further comprise at least one, and preferably
several, ridges 12 that protrude laterally from some of the receptacles 5.
[0044] With reference to Figure 6, it should be noted in particular that ridges 12 are provided
on two adjacent receptacles 5a of one of the wings 3 and on the corresponding receptacle
5b of the other wing 3 that can be inserted between the preceding receptacles, so
as to reduce the useful space for the insertion of the receptacle 5b between the receptacles
5a and increase the pressure or traction to be applied to the wings 3 in order to
close them or open them, respectively.
[0045] Conveniently, there are a plurality of pre-scoring portions 13 formed on the wings
3, which allow to remove a portion of said wing that contains one or more receptacles
5.
[0046] Finally, the package 1 is provided with a covering sheet 14, which is associated
on the layer 7 by adhesive bonding or by other methods and is made of substantially
paper-like material or the like.
[0047] The sheet 14 must be shaped appropriately at the rib 4, so as to allow articulation
of the wings 3.
[0048] At the wings 3, the sheet 14 is coupled to the peripheral portion of the layer 7,
i.e., to the portion that is arranged at the profiles 11.
[0049] Each wing 3 in fact has a scoring line 15, which also passes through the layer 7
and is arranged inside the peripheral portion of said layer that is coupled to the
sheet 14, so as to allow separation of the internal region provided with receptacles
5 of the wing 3, together with the layer 7, from said sheet.
[0050] The scoring lines 15 lie inside the profiles 11.
[0051] The sheet 14 therefore has an outer surface that is always exposed and an inner surface
that is partially visible when the package 1 is open and the internal regions of the
wings 3, together with the layer 7, are spaced from the sheet.
[0052] It is conveniently possible to provide, on such surfaces, descriptive indications
related to the type of product contained, to its methods of use, therapeutic indications
and others, as well as commercial information of any kind.
[0053] The method for manufacturing and filling the package 1 substantially comprises a
step for thermoforming a strip 16 of thermoformable film, in which a plurality of
shells 2 provided with corresponding closure means 8 are obtained, the shells 2 being
distributed along the strip 16 and being arranged so that their respective receptacles
5 are open upward; a step for filling the receptacles 5 with corresponding products;
a step for heat-sealing a protective pierceable film 17 on the shells 2 in order to
close the receptacles 5; a step for pre-cutting each shell 2, in which the folding
lines 6, the pre-scoring portions 13 and the scoring lines 15 are provided simultaneously;
and a step for cutting and separating each shell 2 and the corresponding layer 7,
respectively, from the strip 16 and from the film 17 in order to obtain a substantially
flat package 1.
[0054] Downstream of the forming step there is a step for blanking out the slot that forms
the receptacle 10 on each shell 2.
[0055] The method further provides for performing a step for applying the sheet 14 to the
layer 7, which is performed downstream of said cutting and separation step.
[0056] The method can provide for a step for shaping the sheets 8, which is performed upstream
of the application step; as an alternative, the sheets 8 may be fed in an already-shaped
configuration.
[0057] Finally, the method provides for a step for folding and closing the flat packages
1 so as to obtain said packages in the closed configuration.
[0058] The apparatus for manufacturing and filling the packages 1 and for performing the
method described above is generally designated by the reference numeral 18 and is
shown schematically in Figure 7.
[0059] In Figure 7, the reference numeral 19 designates a unit for discontinuously feeding
the strip 16 of thermoformable film arranged on a horizontal surface; the reference
numeral 20 designates a station for the hot molding of the strip 16, which comprises
a mold 21, constituted by two mold parts, i.e., a lower one 22, which can move alternately
toward and away from the upper one 23, in order to obtain a plurality of shells 2
provided with corresponding closure means 8, which are distributed on the strip 16
along at least one row and arranged so that their corresponding receptacles 5 are
open upward; the reference numeral 24 designates a traditional station for the insertion
of corresponding products in the receptacle 5; the reference numeral 25 designates
a conventional station for feeding and heat-sealing the protective pierceable film
on the thermoformed strip 16 in order to close the receptacles 5, so as to obtain
a plurality of blisters in a flat configuration, distributed on the strip 16; the
reference numeral 26 designates a station for pre-cutting each flat blister along
predefined lines so as to obtain the folding lines 6, the pre-scoring lines 13 and
the scoring lines 15; the reference numeral 27 designates a station for cutting and
separating each flat blister from the strip 16.
[0060] Conveniently, the apparatus 18 is provided with a blanking station 28, which comprises
at least one punch 29 and a corresponding die 30 for cutting the slots that form the
recesses 10.
[0061] The stations 20, 24, 25, 26, 27, 28 are distributed along the feeder unit 19, which
is not shown in detail because it is of a conventional type.
[0062] The feeder unit 19 is provided with a reel 31, which is supported so that it can
rotate freely and is associated with a conventional type of unwinding system.
[0063] The feeder unit 19 further comprises a first unit 32 for drawing the strip 16, which
is arranged downstream of the forming station 21, and a second unit 33 for drawing
said strip, together with the film 17 heat-sealed thereon, which is arranged upstream
of the cutting and separation station 27, the units 31 and 32 not being shown in detail
because they are of a known type.
[0064] The apparatus 18 is of the modular type, and depending on the number of rows of shells
2 obtained on the strip 16 by molding, the subsequent stations are sized with an appropriate
number of work units.
[0065] In the illustrated embodiment, the molding station 20 allows to mold simultaneously
three shells 2, arranged side by side along respective rows.
[0066] The lower mold part 22 is in fact provided with three impressions 34 for molding
respective shells 2.
[0067] Each impression 34 is provided with respective slots 35 and hollows 36, which are
arranged respectively at the profiles 11 and at the receptacles 5 that one wishes
to obtain on the shell 2.
[0068] Conveniently, the impressions 34 are shaped so as to obtain the closure means 8 on
the shells 2.
[0069] The upper mold part 23 acts as a fixed abutment for the lower mold part 22 and is
associated with the molding punches 37, which allow to stretch the strip 16 until
it assumes the shape of said punches.
[0070] The molding station 20 further has conventional means, not shown in the figures,
for injecting compressed air inside the mold 21.
[0071] The molding station further provides a preheating unit 38 upstream of the mold 21.
[0072] The blanking station 28 therefore has three punches 29, which can move below the
strip 16 and are arranged at corresponding shells 2 to be slotted, and an upper die
30, which is also movable and is provided with three holes 39, each arranged at a
corresponding punch 29.
[0073] Conveniently, the blanking station 28 is provided with a system for removing the
process waste by suction, which is not shown in the figures because it is of a known
type.
[0074] The pre-cutting station 26 comprises a fixed upper plate 40, which is provided with
a plurality of blades 41 arranged at the folding lines 6, at the pre-scoring lines
13 and at the scoring lines 15 of the shells 2, and a lower plate 42, which can move
vertically and is provided with three seats 43 for centering respective flat blisters,
at which a plurality of complementary blades 44 for the abutment of the blades 41
are provided.
[0075] Conveniently, the blades 41a arranged at the folding lines 6 and at the pre-scoring
portions 13 have a jagged edge, while the blades 41b, suitable to form the scoring
lines 15, have a straight edge.
[0076] The blades 41 are preferably associated with the upper plate 40 by interposing elastic
springs, which are not visible in the figures.
[0077] Downstream of the cutting and separation station 27 there is a unit 45 with sliders
for removing the resulting flat blisters.
[0078] The apparatus 18 is provided with a station 46 for applying a sheet 14 to each flat
blister conveyed on the removal unit 45 so that the associated layer 7 is directed
upward.
[0079] Advantageously, the apparatus 18 is provided with a station 47 for shaping and feeding
sheets 14 toward the application station 46, which is arranged transversely to the
removal unit 45.
[0080] The station 47 comprises means for supporting the lateral portions of the sheet 14
being processed, and a rectilinear presser 49, which is arranged below the sheet 14
at the centerline thereof and can move alternately in a vertical direction between
a configuration in which it is spaced from the sheet 14 and a configuration in which
it is closer to it; an element 50 for the abutment of the presser 49 in the closer
configuration, which is arranged above the sheet 14, and two claws 51, which are arranged
above the sheet 14 on opposite sides of the presser 49 and are suitable to press the
sheet 14 on the presser 49 in the closer configuration, so as to achieve the intended
shaping of the central portion of said sheet.
[0081] The supporting means 48, not shown in detail in the figures, are constituted by two
flexible elements such as conventional segmented belts, which are closed in a loop
and wound around a driving wheel and a driven wheel and are provided with a side for
loading the sheets 14 to be shaped and with a side for unloading the shaped sheets,
which is arranged proximate to the application station 46.
[0082] The lateral portions of the sheets 14 are arranged so that they rest on said belts,
which are located at a distance that is shorter than the width of the flat sheets
14.
[0083] The driving wheel is associated with step feeder means, which are suitable to actuate
an intermittent advancement of the sheets 14 conveyed on the belts.
[0084] The vertical movement of the presser 49 and of the abutment element 50 is actuated
respectively by a conventional cam mechanism 52 and by a fluid-operated actuator 53.
[0085] The movement of the claws 51 toward and away from each other is actuated by means
of a second cam mechanism 54.
[0086] Finally, the apparatus 18 comprises a station 55 for folding and closing the packages
1 obtained in a flat configuration, said station being arranged downstream of the
removal unit 45.
[0087] The station 55 comprises an element 56 with suckers for gripping each row of flat
packages 1, in order to remove a corresponding package 1 from the removal unit 45;
the grip element 56 is associable in an upper region with respect to the package 1
at the wing 3 located proximate to said element, and can oscillate between a configuration
for picking up the package 1 and configuration for releasing it, said package being
at least partially closed at an unloading station 57.
[0088] The station 55 further has a curved guide 58 for the abutment of the portion of the
package 1 that is spaced from the grip element 56 during transfer from the pick-up
configuration to the release configuration, said guide being suitable to facilitate
the closure of the package 1 on said grip element.
[0089] Finally, the station 55 is provided with first means 59 for pushing the packages
1 released at the unloading station 57 and with presser means 60, which are arranged
above said station and ensure the closure of the packages 1.
[0090] Finally, there are second pusher means 61 for moving the closed packages 1 away from
the unloading station 57.
[0091] Downstream of the station 55 it is possible to provide, for example, additional stations
for the final packaging of the packages 1, which for example can be grouped into units
for sale in trays or other means.
[0092] In practice it has been found that the described invention achieves the proposed
aim and objects, and in particular obtains a package that is practical and safe to
use and has a pleasant appearance.
[0093] The invention thus conceived is susceptible of numerous modifications and variations,
all of which are within the scope of the appended claims.
[0094] All the details may further be replaced with other technically equivalent ones.
[0095] In practice, the materials used, as well as the shapes and dimensions, may be any
according to requirements without thereby abandoning the protective scope of the appended
claims.
