[0001] The present finding refers to a separator or spacer element that is intended to be
associated with the upper part of an ordered group of objects, typically containers
for food and other substances.
[0002] Hereafter, express reference shall be made to bottles and flasks, or even jars or
pots, made from synthetic material or not, or rather containers comprising a hollow
body equipped at the top with a narrow portion with which an end member is associated
defining an undercut, like the one provided by the lower edge of the respective closing
cap or lid.
[0003] Such containers, like for example plastic mineral water bottles, are generally entered
into the commercial network in packages the comprise an ordered group of containers,
for example two, four, six, etc., which are brought together and are in contact with
each other.
[0004] Said groups, usually known as bundles, are generally kept congruent by a plastic
wrapping band, and said band is generally provided with a synthetic tape that provides
a handle for lifting and transporting the bundle.
[0005] Said practical system for packaging in bundles, which uses either a heat-shrinking
synthetic sheet, or exploits the more recent technique of so-called shrink-packing,
is particularly suitable for containers whose body has a straight section that is
generally constant for most of its extension in height.
[0006] The same system lends itself poorly to the packaging of containers whose body is
of a different shape from cylindrical or parallelepiped, for example that has a relatively
long upper portion that tapers upwards, or rather in the direction of the respective
cap.
[0007] Indeed, said consistent tapering ensures that, during the application of said synthetic
band, its clamping force makes the packages lose their verticality, the upper ends
of which are forced towards the inside and group together at the centre of the bundle.
[0008] A purpose of the present finding is that of providing a spacer element that during
the preparation of said bundles is able to keep the respective containers positioned
correctly with respect to each other whatever their shape or configuration.
[0009] Another purpose is that of making a spacer element that combines, as well as said
spacer function, also the function of a gripping member for lifting and transporting
the respective bundle.
[0010] Yet another purpose is that of providing a spacer element or separator suitable for
being associated in a simple and quick manner with the containers constituting the
bundle.
[0011] A further purpose consists of making a spacer element that can be obtained in a simple,
quick and cost-effective manner.
[0012] Said purposes are accomplished thanks to the means indicated in the main claim.
[0013] Preferred embodiments of said means are outlined in the dependent claims.
[0014] The characteristics and constructive advantages of the finding shall become clear
from the following detailed description, made with reference to the attached tables
of drawings, where:
Fig. 1 is a perspective view from above that shows a spacer element according to the
finding.
Fig. 2 is a perspective view similar to the previous one that shows the spacer element
associated with a group of bottles.
Fig. 3 is the section III-III of fig. 2.
Fig. 4 is the section IV-IV of fig. 3.
[0015] From the quoted figures, see in particular fig. 2, it is possible to see a bundle,
wholly indicated with 1, and a spacer element generically indicated with 2.
[0016] The bundle 1 that is shown comprises four identical containers 3 with a circular
plan (fig. 4), for example plastic bottles closed by a normal screw cap 4 (fig. 2)
that sits over an equally normal collar 5 (see figs. 3 and 4).
[0017] Of course, the number of containers 3 can be whatever, provided that they are preferably
even in number, for example two, six, etc.
[0018] Moreover, the containers 3 can be any shape, provided that they are equipped with
a cap or lid as specified in the preamble, or with another equivalent member suitable
for providing an undercut, like for example an analogous body to the quoted collar
5.
[0019] The containers, or bottles, 3 are brought together and in contact with each other
(see figs. 2-4), and are kept congruent by a normal side wrapping band, not shown
for the sake of simplicity.
[0020] The element 2, clearly illustrated in fig. 1, is intended to be fastened to the top
of the containers 3 making up the bundle 1 as represented in figs. 2-4. Said element
2 consists of a shaped body with horizontal extension, usually made from plastic,
which is formed through a suitable technique.
[0021] In the case shown it is obtained by thermoforming from a sheet of synthetic material
equipped with sufficient elasticity.
[0022] The synthetic material constituting said starting sheet can be whatever, provided
that it is suitable for thermoforming.
[0023] Moreover, said starting sheet can be transparent or not, and can have any thickness
suitable for the purpose, like from 0.2 to 2.0 mm.
[0024] As stated, for the quoted forming other advantageous techniques can be exploited,
for example injection moulding, which shall obviously depend upon the material considered
suitable for the purpose.
[0025] As is clearly illustrated in fig. 1, the flat shaped element 2 has a shape in plan
that fits into a square, said square being contained in the shape in plan, also fitting
into a square, of the group of four bottles 3 (see fig. 4).
[0026] Along the perimetric edge of the element 2 runs a channel 6 with complete extension
and with a constant straight section, which has four straight portions alternating
with four curved portions (figs. 1-2) with extension equal to about three-quarters
the circumference.
[0027] Parallel to two opposite straight portions of said channel 6, and close to them,
there are two identical windows 7 that define a rectangular-shaped central band 8,
arranged straddling the respective median line of said square shape in plane of the
element 2.
[0028] Said windows 7 are sized so as to allow the passage of the finger of a hand, in order
to be able to grip said central band 8, which obviously acts as a handle for gripping
and lifting the bundle 1.
[0029] For said lifting, the element 2 is equipped with suitable fastening means of the
bottles 3.
[0030] They comprise four identical openings 9 (fig. 1) that are arranged at the corners
of said square shape of the element 2, immediately inside the curved portions of the
channel 6.
[0031] In particular, each single opening 9 is provided by the upper mouth of a frusto-conical
neck 10 (figs. 1-3).
[0032] The smaller base of said neck 10 has a diameter substantially equal to or slightly
smaller than the average diameter of the lower circular edge of the cap 4 of the bottle
3, and its larger base has a diameter slightly greater than the outer diameter of
the cap itself 4.
[0033] Moreover, the same neck 10 is equipped with a circumferential series of identical
inlets equally angularly spaced apart 11.
[0034] The inner generatrices of said inlets 11 are intended to rest against the side surface
of the part of the collar of the bottle 3 that is situated immediately below the cap
4, and their upper generatrices are intended to engage, from below, with the upper
widened part of the collar of the bottle that defines the screwing seat of the cap
4 and/or with the lower edge thereof.
[0035] Finally, see fig. 3, the larger base of each single neck 10 is connected to the inner
wall of the respective curved portion of channel 6, which inner wall acts as an alignment
seat between caps 4 and openings 9 at the moment of associating the element 2 with
the group of bottles 3.
[0036] Having carried out said alignment, the element 2 is pushed downwards, which involves
the temporary elastic deformation outwards of necks 10 and inlets 11.
[0037] When the necks 10 go past the projecting lower edge of the caps 4, or of the widened
upper portion of the collar of the bottles 3, the necks themselves 10 once again take
up the original configuration, after which, by pulling the element 2 lightly upwards,
they become arranged as specified previously, and as clearly illustrated in figs.
2 to 4.

has been stated previously and from the examination of the attached figures.
