[0001] The invention relates to an element for separating small size and/or large vials
in a rectangular section container, and belongs to the specific field of packaging
vials, for medicinal use, in rectangular section containers of a predetermined capacity.
[0002] As is known, the intrinsic fragility of vials does not allow the placing freely thereof
inside the rectangular section container, and thus the use is rendered necessary of
an element that serves to separate one vial from another and, at the same time, contributes
to the overall strengthening of the pack, preventing the vials from being directly
subjected to the action of any stress at the time of packaging.
[0003] For this purpose, it is customary to use synthetic resin elements moulded on thermoforming
machines that take the form of trays provided with separating elements fashioned directly
out of the plastic film.
[0004] Another solution, that has been present for some time on the market, is constituted
by an element of corrugated section, sometimes strengthened with a flat base, wherein
the alternation of empty spaces and fully moulded parts defines, in each case, a housing
for one vial and a separating element, respectively.
[0005] Whilst, from the functional point of view, the thermoplastic tray solution cannot
be criticized, it has limitations sinee a very costly machine is required for the
production of the trays and thus the overall cost of the product is affected to no
mean extent. Another problem with this particular method comes from the fact that
each size of vial requires a different mould, thereby causing production-costs to
rise still further.
[0006] With the corrugated section solution the disadvantage also exists of it not being
possible to use rationally the space for the placing of the vials in the rectangular
container and, as a result of this, the container having to be oversized in keeping
with the number of vials placed therein.
[0007] The object of the invention is to make available an element for separating small
size and/or large vials in a rectangular container, that is easy to produce, is of
a limited cost, is made of inexpensive material, that allows good use to be made of
the available space and is such that the dimensions thereof can easily be varied.
[0008] Emphasis is given hereinafter to the characteristics of the element according to
the invention, with particular reference to the accompanying tables of drawings, in
which :
- Figure 1 shows, in a perspective view, the blank with the flaps in the "closed"
position;
- Figure 2 shows, in a perspective view, the element with the flaps in the "open"
position and with the vials about to be placed therein;
- Figure 3 shows, in a perspective view with some parts removed, the element in question
inserted in the rectangular container, with each vial inserted in the appropriate
space;
- Figure 4 shows, in a perspective view, a constructional variant for the element
depicted in an identical condition to that shown in Figure 2;
- Figure 5 shows, in a front view, an example for packaging vials in two superposed
layers; Figure 6 shows, in a front view, an example for packaging vials in two layers
in accordance with the variant depicted in Figure 4.
[0009] With reference to the said figures, shown at 1 is an element constituted essentially
by a sheet 2, in particular of cardboard, provided with parallel separating flaps
3 that are cut out of the said sheet 2, hinged, with respect thereto, along an axis
3a.
[0010] The said flaps 3, from the closed position (Figure 1), are placed in the operative
position (Figure 2) through pressure applied thereon (arrow F) and a consequent rotation
of each flap around the corresponding axis 3a. The said "pressure" is applied by known
means that are not illustrated and are extraneous to the invention described herein.
[0011] Each flap is complementary to a corresponding slot 3b made in the said sheet 2. When
in the operative position, the said flaps 3 are placed in a plane perpendicular to
the said sheet 2 and, in this way, define a plurality of spaces 4 able to accept an
identical plurality of vials 5 (Figure 2).
[0012] At 6 is shown a rectangular section container in the form of a carton destined to
receive freely, at one open end, a unit constituted by an element 1 and vials 5 (Figure
3).
[0013] In the constructional variant shown in Figure 4, two lateral flaps 2b are provided,
formed by folding the said sheet 2, parallel to the said separating flaps 3 and oriented
identically thereto. The said lateral flaps 2b render easier the insertion of the
said unit into the container.
[0014] Shown at F
1 and F
2 in a first embodiment (Figure 5) and a second embodiment (Figure 6) are two superposed
rows of vials inserted in a suitably sized rectangular section container.
[0015] Thanks to the particular conformation of the element according to the invention,
an extremely simple and inexpensive blank can be used for the formation thereof, and
the dimensions can easily be varied to suit the type of vial destined to bo accepted.
[0016] Another particularly advantageous feature of the invention is the optimum use made
of the available space since the area taken up by the element in question is reduced
to a bare minimum.
[0017] It is understood that the foregoing description has been given purely as an unlimited
example and thus that eventual variants of a constructional nature (for example flaps
3 provided in one single piece with a sheet 2 devoid of slots 3) fall within the framework
of protection afforded to the invention as described above and claimed hereinafter.
1. Element for separating small size and/or large vials in a rectangular section container,
characterized by the fact of comprising a sheet 2 in which a plurality of parallel
flaps 3 define a number of spaces 4 destined to receive therein an identical number
of small size and/or large vials 5, with the. unit constituted by the element 1 and
the vials 5 able to be inserted freely into the said rectangular section container
6.
2. Element according to Claim 1, characterized by the fact that the parallel flaps
3 are cut out of the sheet 2, are hinged, with respect to the edge common to the latter,
along Dn axis 3a, and are complementary to an identical number of slots 3b provided in the
said sheet.
3. Element according to Claim 1, characterized by the fact of being provided with
two additional lateral flaps 2b made by folding the said sheet 2 and parallel to the
other separating flaps 3.
4. Element according to Claim 1, characterized by the fact that the sheet 2 and the
separating flaps 3 are fashioned out of the same blank.
5. Element according to any one of the preceding claims, characterized by the fact
that the said flaps are parallel to one side of the sheet.
6. Element according to Claim 4, characterized by the fact that the said blank is
made of cardboard.
