[0001] The present invention concerns a system for dispensing, one by one, capsular products
like tablets, pastilles, confectionery products, pills, solid medical products and
the like, in small doses, said system comprising at least: - 1) container means: -
2) entrapping (encapsulating) means which carrier said products; - 3) opening and
closing means of said container means; - 4) partial break means of said encapsulation
and transport means; 5) means for the break of means 2) and for the outlet of said
single encapsulated.
[0002] In a particularly simple, compact and effective embodiment, the system according
to the invention has the structure of a cylindrical or parallelepiped case or box
open at least on one side closable at least by a poly functional tap 3), in which
box are introduced strips or necklaces (2) formed of at least two substantially thermoplastic
films or sheets with characteristics diversity, welded to each other so to embed said
products to singularly dispense, one of the necklace forming sheets being broken in
its crossing a pass-no-pass device obtained from the cooperation of members associated
to the poly functional tap (3) and of a wall projecting inside the container, which
wall acts also as support of the necklace trailing device.
[0003] The invention concerns also a method to functionally embody said system, in which
after: - having embedded said capsules, tablets, confectionary products and the like,
between two films of characteristics diversity and having united them (with an adhesive
and/or a seal); - having anchored a border or edge of said strip or necklace to a
dragging device placed and supported on a not-central box portion so to allow the
user's manual action; and - having associated the opening/closing door, it is possible
to carry out at least: i) a trailing phase of the composite film; ii) a contact phase
of the minor sector of the pastille container with two mini- zones of the pass-no-pass
mechanism formed of elements associated, on one side, to the tap and, on the other
side, to said box; and - iii) a phase of breaking the weaker film to expel and dispense
to the user the involved capsule.
Prior Art
[0004] Pills dispensers and systems are known and commercialized, comprising, isolatedly
or in combination, elements selected from the group consisting of: - a box, a tap
(with or without a small opening-closing door); - pills embedding and carrying means;
- trailing means; - break means.
[0005] US Patent n° 4.163.496 describes a pills dispenser consisting of a top opened box and of a release closure
element with two tongues aligned but remote to each other.
US Patent n° 4.538.731 discloses a small flip-top container of small solid products, in particular of pastilles
and the like, comprising a closure consisting of only one snap door. In the
US Patent n° 4.733.797 the pills are sealingly enclosed in capsules or shells carried by a plastic segmented
film or by a leaf like strip.
[0008] The variegated panorama of the "patent crowded field" of the dispensers can be completed
by referring to the recent PCT-Publication
WO 2004/009470A2 related to a distributor of medical products in different doses with the aid of a
dispensing mechanism, comprising: - reception means of the medicament carrier; - means
to release a dose; - on outlet; - dose indexing means; and - counting means.
[0009] The Prior Art dispensers associate to various advantageous characteristics a number
of inconveniences whereby the market has punished or confined them to a few small
niches.
[0010] First object of the present invention is to provide a system to dispense confectionary
or pharmaceutical products which does not show the Prior Art drawbacks and, above
all, is simple, effective, silent and easy to operate.
[0011] An other object of the invention is a method to manage and pilot said system in order
to easily realize regular dispenses of single pill-form products by easily breaking
the means which encapsulates and carries same tablets.
[0012] The system according to the invention to dispense from a box or container (I CC),
single (one by one) solid products with the shape of candies, chocolates, sugar -
coated pills, pastilles, capsules, tablets and the like, entrapped in a supporting
and transporting member comprises: - as carrier member; - a complex film of at least
two layers having diversity of thickness, treatment and/or mechanical resistance (IV
COL); - as box or container (I CC), a parallelepiped or cylindrical body having at
least one open side in which are applied a tap (II T) with a small opening - closing
door (A-C) and a trailing mechanism (III MT) to which shall be hooked the free edge
or border (LE) of finished pieces of necklaces (COL) of said complex film embedding
finite series of said solid products (CA, PM) to dispense.
[0013] The method according to the invention comprises the steps of:
- preparing at least two films with diversity of thickness, brittleness and resistance
to forces of tensile stress and break cut;
- making holes and/or notches in the film showing minor thickness and resistance;
- making possible ovular semi seats in the other film having major thickness and resistance;
- adhering one film to the other preferably by welding;
- making continuous necklaces of encapsulated products, said necklaces being obtained
by welded overlapping of said two films;
- inserting in succession said necklaces in a container body (I) comprising at least
one opening/closing means (II) and a trailing (tow) means which preferably collects/recovers
the more resistant and thicker film;
- applying one inner free end or border of said necklace to said trailing means;
- acting on said trailing means in several steps, particularly in three steps so to
realize at least a first phase of trailing said necklace, a second phase to bring
the encapsulated products in contact with at least two shoulders of a pass-no-pass
device; and
- a third phase to force said contact by further trailing up to the break of the weak
film in order to obtain an opening adequate to the extraction of the product.
[0014] Further characteristics are recited in the claims which are at the end of this description
but are considered herewith incorporated.
[0015] The various features and advantages of the present invention become better understood
with regard to the following description, appended claims, and accompanying drawings
where:
- figures 1, 3, 3A, 3B, 4, 4A, 5, 5A, 6 and 6A are schematic prospective views of an
embodiment;
- figures 2, 2A, 5F, 5AF, 6F and 6AF are front views;
- figures 6P and 6AP are top views;
- figures 7 are front views on enlarged scale of the pass-no-pass mechanism in its three
working phases; and
- figure 8 is the block diagram of a process embodiment.
[0016] In the above figures in particular in fig. 1 and in the relevant front views of figures
2 and 2A, the dispenser system according to the invention is schematically shown as
essentially comprising: I)a container body CC; - II) a closing member or tap; III)
a trailing (tow) mechanism MT; and - IV) a collector - carrier of the products to
dispense, for instance tablets, sweet-meals etc. CA.
[0017] The container I. CC can have a polygonal (especially rectangular, square, trapezoidal
etc.) cross section as in the figures 1, 2, 2A, 4, 5, 5A, 5F, 5AF, 5P, 5AP, or round
in particular with a circular, elliptical etc. cross section.
[0018] These container bodies or boxes I CC have a closed bottom 12 which is preferably
integral with the side/polygonal walls f.i. 5R, 5'R or cylindrical wall 5C.
[0019] The top of the container body I CC (independently from its polygonal or cylindrical
cross section) is open to be associated to a trai/tow mechanism II. MT having a substantially
stationary closing portion or tap T, and to an opening - closing portion A - C with
a small door SPO rotatable (over an angle of 90°) around an articulation line LA coincident
with the inner end of tap T, the other outer end being free. The articulated portion
of A-C terminates, at its distal end, with a bent spout Z which is shaped to be associated
by form coupling to the upper end 20 of the wall 5'R when the articulated portion
A-C is taken down and aligned with the stationary portion of tap T so to seal/dose
the mouth BO of the container or box I.
[0020] When said turnable portion A-C with opening - closing door SPO is rotated upwardly
at right - hand (fig. 1), it forms said mouth BO for the outlet of said candies CA
(fig. 2) or medical tablets PM (fig. 3A); therefore the length of the door SPO of
A-C from the articulation line LA up to the protuberance Z is such to correspond to
a virtual radius of the hatched curve 21 (stroke of Z from the opening position to
the closing position) slightly higher than the major dimension of the products to
be dispensed.
[0021] Characteristically the right-hand wall 5R of the polygonal box (fig. 2) or wall 5C
of the cylindrical box (fig. 2A) is shorter than the left-hand wall 5R or 5'R and
ends upwardly with a thickened portion 20' at the lower end 29 of which engages the
inner end of a third projecting wall 23, and at the upper portion 28 of which engages
a fitting connector 30 between the corner 40 at the inner end of tap T and the chamfer
28 of the short wall 5R, 5C.
[0022] This fitting connection has also the function to act as support of the rod 1 of the
trailing mechanism MT at the end of which two sprocket wheels 3-3' are engaged. As
it can be seen from figures 3 and 3A, said rod 1 projects slightly beyond the toothed
wheels with protrusions 2-2' (fig. 3B) which slip in "ad hoc" seats (not shown) made
preferably inside the two facing walls of the fitting connector 30. The rod 1 has
preferably a slot 1' within which slips the border LE at the inner end of the composite
sheet FF, FF' embedding the pastilles.
[0023] Figure 3 shows the case of sweetmeats or candies having a major dimension L, which,
according to the invention, are encapsulated between two substantially thermoplastic
PaR-PST sheets having mechanical characteristics diversity: the upper easily breakable
sheet (PaR) can show a series of small holes BU and/or incisions IN; the lower sheet
PST is more resistant (ticker and/or not weakened) than PaR and acts as trailer. Once
the sweetmeats (confetto) CA are entrapped between the two sheets PaR and PST, said
sheets are united (by welding or adhesive) and form a two-layer film FF which encloses
said capsules and candies CA. In the case of the figure 3 the two sheets PaR and PST
can have a width LA lower than the major dimension of confetto CA which will be covered
at its ends: indeed sweetmeats, confetti, pastilles of confectionery etc. do not require
a total coverage and thus a total protection.
[0024] In fig. 3A the case is shown of medical pills (tablets) PM f.i. round with a diameter
DM, which are inserted between the two sheets PaR (with incisions IN) and PST (without
weaknesses) both having a width LA' slightly above said diameter DM whereby the products
PM will be entirely covered and protected at the moment of the two films welding with
formation of a bilayer film FF'.
[0025] The pitch i.e. the distance between successive confetti CA or pills PM will substantially
depend on their weight and size. The third wall 23 shows also a small tooth 23' which
by inserting itsself between two rocket teeth 3, 3' acts as a no-return device.
[0026] In the case of non medical products such as sugarmeats, candies etc., optimal results
have been obtained with a lower trailing film PST consisting of a laminate of polyester
(PET)-aluminium (All)- polyethylene (PE) having thicknesses comprised in the hereunder
ranges (in microns):
PET 19 -23, Adhesive (AD)- All 7-25, Adhesive-PE 20-25.
[0027] In the absence of barrier, the All-sheet can be eliminated. As upper film PaR has
been advantageously utilized a triple laminate:
PET 5-22, (AD) - All 7 - (AD) - PE 20-25
[0028] Here too, if there is not need of a gas barrier, the metallic film can be eliminated
or alternatively a mono-layer polyolefin film with a thickness of about 35 µ preferably
containing additives or treated with fancy-cut applied on the surface of only one
film preferably that of the PE layer, or of both PE and PET films, can be used.
[0029] Fig. 4 is a perspective view of a dispenser with rectangular cross-section box I
CC whereas in fig. 4A the version with a cylindrical box 5C in shown, at a parity
of trailing means MT and of opening - closing means T, A-C, SPO.
[0030] In figures 5 and 5A (perspective views), 5F and 5AF (front view) and 5P, 5AP (top
view) the version is shown of the dispenser of the figures 1, 2 and 2A, additionally
provided with a device to protect children, substantially consisting of an over-tap
ST with opening-closing door A-C, SPO having now also a central window F.
[0031] Typically the body ST-AC-SPO can be translated and pass from the initial position
of figures 5, 5P and 5F in which said body is stopped under the action of several
teeth in particular those 60 and 61 associated to two lateral keys 60" and 61" and
that 63 associated to the door A-C. To pass to the dispense or distribution, the two
side keys 60", 61" are pressed in the direction of arrow 63', and the tooth 63 is
released by lifting door A-C in the direction of arrow 63', whereby the whole over-top
ST with window F can be translated from the compact position 70 of fig. 5P to the
cantilever position 71 of figures 5A, 5F, 5AF where the small window F, which was
blind before i.e. did not make visible the inner wall MT and, above all, blocked the
outlet mouth of the medical pill PM, now thanks to the partial lifting of door A-C
in the position 63" where the mouth becomes free and contemporaneously the small toothed
wheels R1 and R2 become accessible (in the position in 70 they were not accessible),
the ergonometric action in the direction of arrow 68 becomes possible as in the old
cigarette lighters i.e. with a very natural acting gesture.
[0032] Figure 6 shows the children protecting device associated to a cylindrical container:
here the three keys T1, T2, T3 are pressed releasing the teeth thereto associated,
the over-tap ST is turned in the direction of arrow 69 whereby the dispensing mouth
is freed and the toothed wheels (priory hidden) become accessible. The working is
substantially similar to that of the polygonal containers.
[0033] In the figures 7, 7A, 7B (front views) are shown, on enlarged scale, the steps of:
I) sliding of the composite sheet PaR + PST under the action of the trailing mechanism
MT;
II) contact of the coated tables PM in at least two points 36-36' of the tap element
T with that of the third cantilevered wall 23 of box ICC;
III) break of the upper film PaR which under the tensioned contact effect in said
points 36 - 36' in the direction of arrows X-Y and the continuing trailing action
of the trail mechanism MT, is submitted to a force in the direction of arrow Z which
causes the break and the detaching of the weakened sheet PaR and the outlet of the
tablet PM through the mouth BO.
[0034] Characteristically the pass- no - pass device P-N-P is here formed by the sides (or
inclined chamfers) 31 of T extending (from 34 to 35) and 32' (from 27 to 38) of the
projecting wall 23, which chamfers or bevels are mutually aligned or form an angle
lower than 15° depending on the size, weight and consistency of the tablet PM (or
CA). The contact points 36 - 36' excert pressure in the directions of arrows X, Y
against said chamfers 34 - 35 and 37 - 38 and generate a radial reaction force (indicated
with the arrow Z) which causes the break of PaR, and the expulsion of tablet PM, without
any damage to the thick trailing film PST that can therefore be recovered and recycled.
[0035] In the block diagram of fig. 8, the reference 80 indicates a bobbin of basic film
which is treated in 81 to get the break sheet PaR To the station of block 82 arrive
the thick tow sheet PST from the bobbin 80' and the candies CA or tablets PM from
the hopper 85, which are carefully put down in PST and covered by the sheet PaR 81'
in outlet from the treatment 81. In 84 the package formed of PaR - tablets CA or PM,
and PST is welded, the composite film FF (or FF') is inserted in the container I.CC
and in the pass - no- pass PNP and is engaged with its border LE to the slit of rod
1 of the tow mechanism M. This last mechanism carries out a first sliding tow in several
steps preferably in three steps, i.e. in 85 a first sliding drag of FF (step I), a
second tow in 86 to take in succession the tablets PM (or CA) embedded in FF into
contact in at least two points with the pass - no - pass PNP (step II) and a third
tow in 87 (step III) to force the tablets in a manner to exert a quasi radial stress
on FF up to break the weaker film PaR.
[0036] At the outlet 87 are collected: - the now free tablets 83 or capsules CA or PM; -
the wastes or residues 81" of the now broken sheet PaR; and - the (not broken) thick
tow sheet PST which is rewound on 80' and recycled to the station 82.
