    Description

    (1) Further features and advantages will become apparent from the following detailed description of some preferred embodiments of the invention, given purely by way of non-restrictive example, with reference to the attached drawings, in which:

    (2) FIG. 1 is a front view of a first example of a support for a unit dose product according to the invention, in the assembled configuration;

    (3) FIG. 2 is a section along the line II-II in FIG. 1;

    (4) FIG. 3 is a rear view of the example of a support in FIG. 1, in the direction of the arrow III in FIG. 2;

    (5) FIG. 4 is a rear view of the example of a support in the previous figures, assembled with a different unit dose product having a blister pack different from the one in FIGS. 1 to 3;

    (6) FIG. 5 is a section similar to that in FIG. 2, showing the support in the previous figures, assembled with a unit dose product contained in a different pack;

    (7) FIG. 6 is a view of a card made of material configured for producing the support for a unit dose product as in FIGS. 1 to 5;

    (8) FIGS. 7A and 7B to 13A and 13B illustrate diagrammatically other variants of a support for a unit dose according to the present invention, respectively in configurations before and after their assembly; and

    (9) FIG. 14 is a diagrammatic view of the steps of producing and assembling a support for unit dose products according to the invention.

    (10) In the present description, the term card is used for identifying the support structure to which the product packaged in unit doses is connected. The term card must not, however, be understood in restrictive terms that limit its shape or material or other features thereof. The term card should, however, be understood as a summarising expression since the support structure has a relatively small thickness compared with the other two dimensions, and since the combination of this small thickness and the material used to produce the support structure, i.e. the card, make it possiblewith the aid of a zone of weakened material if necessaryto fold one portion thereof over another, as will be described more clearly below.

    (11) With reference now to FIGS. 1 to 3, a support 10 for a unit dose product comprises a card 11, for example a sheet of cardboard or laminated paper, a layer of plastic material, a slim metal plate or similar, having a main portion 12 and a flap 13 folded along a fold line X-X, corresponding to one edge of the support 10 in the assembled configuration shown in the figures. The flap 13 is only partly superimposed on the main portion 12 and is fastened thereto along part or all of a peripheral edge zone 15, indicated conventionally by hatching in FIG. 1. Depending on the material of the card 11 and/or the production technology used, fastening can be done by welding or gluing, or by means of mechanical fastening using staples or the like. Preferably, but not restrictively, the material of the card 11 is a plastics material and the flap 13 is joined to the main portion 12 by ultrasonic welding. Ultrasonic welding prevents generalised heating of the material and therefore does not alter the characteristics of the unit dose product, which is particularly advantageous in the case of a drug. Ultrasonic welding also proves convenient with respect to gluing because no additional material is involved. In some cases, depending on the rigidity of the material of the card 11 and on the particular type of fold made in order to bring the flap 13 over the main portion 12, it is not necessary to fasten the edge along the fold line X.

    (12) A hole 30 can be made in the main portion 12 of the card 11, which hole is useful for hanging the support for a unit dose product 10, for example in the store with pegs described in EP 1346929 from the same applicant. On the main portion 12 of the card 11, for example in the zone of its face 12a left free by the flap 13 and/or on the other face 12b, opposite that to which the flap 13 is fastened, it is possible to add information 31 for identifying the unit dose product. The information 31 can be added by writing directly on the main portion 12, for example by printing or engraving, or by other known means, or by fastening a label or other pre-printed item to the main portion 12. The information 31 can also be stored on an RFID tag or other similar components to be fastened to the main portion 12 of the card 11. The information 31 can be represented in any known manner, either as plain text or using a bar code, QR code or the like.

    (13) A blister pack 14 of a unit dose product is held between the main portion 12 and the flap 13 of the card 11. As will be seen more clearly below, the invention is not limited to the support for unit dose products contained in blister packs, but can advantageously also be adapted for use with unit dose products in different packs, such as sachets or packets, of the type generally used in the sector of unit dose products of the pharmaceutical type.

    (14) The blister pack 14 comprises a blister 16, inside which a unit dose product P is housed, for example a pill or a tablet of a drug. The blister 16, generally made of plastics material, comprises a peripheral edge 17 and is sealed by a film 18, usually made of metal or paper, welded to the peripheral edge 17. As is known, by pressing on the blister 16, it is possible to remove the unit dose product P as necessary from the blister pack 14, breaking the film 18.

    (15) A main opening 20 is made in the main portion 12 of the card 11, into which opening the blister 16 of the blister pack 14 is inserted. The dimensions of the main opening 20 are such that the blister 16 can protrude from the main portion 12 of the card 11, from the part opposite the flap 13, while the peripheral edge 17 of the blister pack 14 is, at least in part, wider than the main opening 20 such that it remains positioned between the main portion 12 and the flap 13 superimposed thereon and fastened thereto.

    (16) A secondary opening 22 is made in the flap 13, which secondary opening is substantially centred relative to the main opening 20. It is possible to remove the product P through the secondary opening 22 when the blister 16 of the blister pack 14 is squeezed during use.

    (17) The main opening 20 shown in the non-restrictive example in FIGS. 1 to 3 is substantially rectangular in shape, with rounded corners, or generally elongated and slot-shaped. The long side of the main opening is positioned transversely to the width of the card 11. The secondary opening 22 in this example is the same size as the main opening 20 and is completely superimposed thereon. The main opening 20, which is elongated and slot-shaped, can conveniently accommodate the blister 16 of a blister pack 14 of corresponding shape, of the type used for example for packaging pills of elongated shape, such as the pill P shown in the example in FIGS. 1 to 3. The corresponding shape of the secondary opening 22 then makes it possible to remove the pill P conveniently from the blister 16, without the user noticing any significant difference from removing a pill from an ordinary type of blister pack. In fact, the film 18 that seals the blister 16 can be broken without difficulty after pressure is exerted on the pill P when squeezing the blister 16, and the pill P can easily come out of the blister pack 14 because the width of the secondary opening 22 corresponds substantially to the width of the mouth of the blister 16. Furthermore, the card 11 is fairly slim and therefore does not pose an obstacle to removing the pill P.

    (18) The card 11 is preferably made of a flexible, but nonetheless not too soft or yielding, material. In this way it is possible to produce a reaction on the card 11 in order to remove the unit dose product from the blister pack, so as to compensate for the difficulty of using just the peripheral edge 17, which is generally small. In this respect, the present invention resolves a problem of the prior art, in which the unit dose products are inserted into sachets, which serve only for storing the products.

    (19) When, as in the example in FIGS. 1 to 3, the secondary opening 22 is large and corresponds substantially to the size of the mouth of the blister 16 of the blister pack 14, it is possible to read, through the same, at least part of the information usually printed on the film 18 that seals the blister 16. It is thereby possible to inspect the unit dose product associated with the support 10. Even more preferably, the material of the card 11 is transparent so that, irrespective of the size of the secondary opening 22, the information printed on the film 18 of the blister pack 14 can be read through the flap 13.

    (20) The shape of the main opening 20, elongated in the shape of a slot or rectangular with rounded corners, or more generally oblong, as illustrated in FIGS. 1 to 3, can advantageously also be used in association with blister packs other than oblong ones. In other words, the size and shape of the main opening 20 are not necessarily linked to the shape of the blister of the unit dose blister pack, even thoughas will be demonstrated belowit is possible and advantageous to produce a production line, even on an industrial scale, in which the main opening 20 and/or the secondary opening 22 differ from product to product.

    (21) As illustrated in FIG. 4, the same support 10 for a unit dose product can be used for a product P, for example a tablet, contained in a blister pack 14 having a blister 16 shaped substantially as a segment of a sphere. In this case, the blister 16 of the blister pack 14, while protruding from the main opening 20, does not occupy the whole width thereof and, depending on the rigidity of the material of the card 11, and the looser or tighter fastening of the flap 13 to the main portion 12, it can be displaced relatively easily along the main opening 20 if necessary, without however coming out of said opening.

    (22) The provision of a wide secondary opening 22 is advantageous where, as illustrated in FIG. 5, a unit dose product P is not housed in a blister pack, but in a packet 34 that does not have a flat side but is provided with an end edge 36 that can be held between the main portion 12 of the card 11 and the flap 13. The packet 34, which in a typical but non-restrictive exemplary case can contain a suppository S or other unit dose product, can protrude from both sides of the support 10.

    (23) As can be seen in FIG. 6, the support 10 for a unit dose product described above is advantageously produced on the basis of a card 11 made of material that has some degree of flexibility, but is not too yielding or soft. Preferably, the card 11 is a thin sheet of plastics material, but as mentioned above different materials can also be used for the purpose, such as a sheet of cardboard or laminated paper, a slim metal plate or the like. When the support 10 is in its unassembled state, the card 11 has the flap 13 unfolded on the same plane as the main portion 12. The main opening 20 and the secondary opening 22, which in this non-restrictive example are the same shape and size, but whichas will be seen below, can also differ from one anotherare made in a symmetrical position relative to the transverse fold line X-X. The transverse fold line X-X can simply be a geometric line, or can be marked on the card 11 by an actual incision or notch or a line of weakening of the material of the card 11, for easier folding, especially in the case of material that is not too thin or is inflexible.

    (24) FIGS. 7A and 7B show a variant of the support 10 for a unit dose product, respectively in the configuration of the card 11 before assembly and in the assembled configuration of the support 10. This variant of the support 10 is particularly suitable for a drug or other product packaged in a sachet 40, such as a soluble oral product, a soluble powder, a sterile gauze, etc. To open a pack of this kind it is normally necessary to tear off an end strip thereof. The support 10 can therefore be produced in such a way as to have a single opening or aperture 42 made half on the main portion 12 and the other half on the flap 13 of the card 11. When the flap 13 is folded over and fastened to the main portion 12, the edge of the support 10 corresponding to the fold line X-X is interrupted by the opening 42, leaving one side 41 of the sachet 40 exposed, while the other sides of the sachet are held tight between the flap 13 and the main portion of the card 11. In this case, the weld 15 between the flap 13 and the main portion 12 should be made on just three sides, excluding the edge of the support 10 corresponding to the fold line X-X.

    (25) FIGS. 8A and 8B show a variant of the support 10 for a unit dose product, respectively in the configuration of the card 11 before assembly and in the assembled configuration of the support 10. This variant of the support 10 is produced in particular for a product P, for example a tablet, contained in a blister pack 14 having a blister 16 substantially in the shape of a segment of a sphere. In this case, unlike the variant in FIG. 4, the blister 16 of the blister pack 14 is surrounded by the edge of a circular main opening 20. The secondary opening 22 is also circular with dimensions substantially corresponding to the main opening 20, so as to be superimposed thereon in the assembled configuration of the support 10, illustrated in FIG. 8B, with the flap 13 superimposed on and fastened to the main portion 12 of the card 11. In this case, the weld 15 can be made on all or part of the peripheral contour of the flap 13.

    (26) FIGS. 9A and 9B show a variant of the support 10, in which a wide opening 43 is made in the main portion 12 and in the flap 13 of the card 11, which opening extends as far as the end of the flap 13, which end is reduced to two branches 13a, 13b. In the folded configuration illustrated in FIG. 9B, the two branches 13a, 13b are folded over the main portion 12 of the card 11, to which they are fastened as described above, for example by welding or gluing in the hatched zones 15 in the figure. The support 10 can be accessed from outside the pack of the drug contained therein, so as to allowas in the example in FIGS. 7A and 7Bthe edge 41 thereof to be torn off in the case where this is a sachet 42.

    (27) FIGS. 10A; 10B to 13A and 13B show other variants of the card 11, illustrated respectively before and after the flap 13 is folded over the main portion 12. To simplify illustration, no representation has been given of the pack of unit dose product that, when the card 11 is folded, is contained between the flap 13 and the main portion 12 so as to form the support for the unit dose product referred to in the present invention.

    (28) FIGS. 10A and 10B show a variant of the support 10 in which two wide openings 44, 46, which are symmetrical relative to the fold line X-X, are made in the main portion 12 and in the flap 13 of the card 11. A lateral portion of the card 11 is also removed in the area of the fold line X-X, so that the resulting card 11 has a branch 47 at the fold line X-X and two symmetrically facing branches 48, 49 on the main portion and on the flap 13. In the folded configuration illustrated in FIG. 10B, in which the possible weld 15 is shown as hatching, the support 10 can be accessed from outside the pack of the drug contained in the support 10, so as to allowas in the examples in FIGS. 7A, 7B and 9A and 9Bthe edge thereof to be torn off in the case where this is a sachet.

    (29) FIGS. 11A and 11B show a configuration of the card 11 similar to that in FIGS. 10A and 10B, in which, however, as well as the wide openings 44, 46, which are symmetrical relative to the fold line X-X, only a small portion of the card 11 that connects said openings 44, 46 is removed in the area of the fold line X-X, thus creating a single branch 47 at the fold line X-X. When the card 11 is in the folded configuration shown in FIG. 11B, this variant leaves a small open segment on the folded edge, which is useful, as in the examples in FIGS. 7A, 7B; 9A, 9B and 10A and 10B, for access to a strip of a sachet that is contained between the flap 13 and the main portion 12.

    (30) FIGS. 12A and 12B show a variant of the support 10 in which an opening 50 is made in the main portion 12 and is capable of housing for example the blister of a blister pack for a unit dose product, as already described above with reference to FIGS. 1 to 4. It should be noted that the opening 50 can be of the desired shape and size, for example the opening 22 can be oblong in shape as in FIGS. 1 to 4, or circular in shape as in FIGS. 8A and 8B. The size of the opening 50 is also not restrictive, but can vary depending on the size of the blister of the blister pack of the unit dose product to be connected to the card 11. In this particular variant, rather than a complete opening, simply a notch 52 that will form a tab 54 is made in the flap 13. When the card 11 is folded, as shown in FIG. 12B, the tab 54 can be folded so as to allow the unit dose product to come out when the blister of the blister pack is squeezed. In this variant, the film that seals the blister of the blister pack is more protective than in the variants illustrated previously, which provide an actual opening in the flap 13 of the card 11.

    (31) FIGS. 13A and 13B show a variant of the support 10 referred to in FIGS. 12A and 12B, but in which the tab 54 can bend in the opposite direction because of a notch 52 made in a different manner.

    (32) Naturally, the notches 52, 52 illustrated in the previous figures by way of example can be made in the flap 13 by different methods and having different shapes. For example, a cross-shaped notch could be made, which is substantially centredwhen the card 11 is in the folded configurationso as to have the centre of the opening made in the main portion. Partial notches, or pre-cuts, could then be made so that the material of the flap 13 corresponding thereto could be broken just by applying pressure to make the unit dose product come out of the blister pack connected to the card 11 of the support 10.

    (33) Production of the support for a unit dose product according to the invention can easily be automated, and carried out by means of an industrial plant that provides high productivity and is flexible in relation to the shape of the unit dose products that enter it.

    (34) FIG. 14 diagrammatically shows the steps of producing a support 10 for a unit dose of the type described above.

    (35) In a first step A, a band 60 of material from which the card 11 is made is cut to produce the desired openings therein. In the example in FIG. 14, the openings 20, 22 of the support example described previously, and the hole 30, are made in the band 60. Other kinds of cutting and shearing 61 can also be done to give the card 11 the desired final shape. Subsequently, in step B, the band 60 is cut transversely to produce the individual strips 11. Preferably, the strips 11 are made in the transverse direction of the band 60, so that the flaps 13 are turned to face one side of the band 60 (at the bottom in FIG. 13) and are thus accessible to a folding tool without it being necessary to move the strips 11 apart, or excessively apart, from one another. The information 31 is then put on each card 11 produced from the band 60. A blister pack 14 for a unit dose product P is then connected to the card 11, inserting the blister 16 into the main opening 20 made in the main portion of the card 11. Preferably, the unit dose product is connected to the card 11 immediately after or immediately before the information is added on the card 11, to avoid errors. Next, the flap 13 is folded over the main portion 12 of the card 11. The next step involves welding or gluing the flap 13 onto the main portion 12 along the zone 15. The support 10 for a unit dose product P is then complete and ready for the subsequent handling thereof.

    (36) Naturally, without prejudice to the principle of the invention, the embodiments and the implementation details can vary greatly from what is described and illustrated, while remaining within the scope of the present invention.
