[0001] The box of the invention packs bottles on sides thereof; it can also be used for
packing other products which can be vertically manipulated during packing and for
which packing on the side of the product is preferred or requested.
[0002] At present a box commonly known as RSC (Regular Slotted Case) is used for this purpose.
[0003] The boxes are obtained from a pre-cut cardboard sheet which is a flat right-angled
parallelepiped. The sheet exhibits a plurality of transversal fold lines which separate
the four lateral faces of the box. The two base surfaces are constituted by a plurality
of appendices, or flaps, each connected to a respective lateral face along a longitudinal
fold line. The flaps are foldable at a right angle with respect to the lateral faces
and are superposable one on another in order to be reciprocally fixed, for example
by gluing. One of the lateral faces located at an end of the pre-cut sheet also exhibits
a flap connected to the end along a fold line. This flap is folded and glued internally
to the opposite lateral face, in order to join the box, which is maintained in a flattened
configuration before passing on to the process in which the products will be introduced
there-into.
[0004] A drawback of this type of box concerns the opening of the box to gain access to
the products contained in it.
[0005] Usually a perforation is exhibited on one of the surfaces of the box, defining a
tear-off strip, affording a sort of window through which the products can be extracted.
This solution is not very practical as imprecision in the perforation leads to difficulty
in opening the box as well as ugly tears on the surface of the box which give the
whole a damaged look, making it unsuitable for location in a display area of a sales
point. Also this tearing system means that the box cannot be closed again once torn
open.
[0006] The main aim of the present invention is to provide a box for packing bottles which
offers a practical and precise opening system and which also enables the box to be
re-closed.
[0007] Further characteristics and advantages of the present invention will better emerge
from the detailed description that follows, of a preferred but not exclusive embodiment
of a bottle-packing box, illustrated purely by way of example in the accompanying
figures of the drawings, in which:
figure 1 is a plan view of a cut sheet for realizing a tradition tear-open box;
figure 2 is a plan view of a cut sheet for realizing a box according to the present
invention;
figure 2a is a perspective view of the sheet of figure 2, folded and pre-glued; figure
3 is a perspective view of the box of the present invention obtained by folding and
gluing the sheet of figure 2;
figure 4 is a perspective view of the box of figure 3, in an open configuration; figure
5 is a perspective view of the box of figure 3 in a re-closed configuration.
[0008] With reference to the figures of the drawings, 1 denotes in its entirety a box according
to the present invention.
[0009] The box can be fashioned by folding and fixing a pre-cut sheet, made for example
of corrugated cardboard. The base sheet is a flat development of a right-angled parallelepiped.
The sheet exhibits at least four consecutive lateral sides 2, 3, 4, 5, reciprocally
connected by common sides constituted by transversal fold lines 23, 34, 45. The surfaces
have been termed "lateral" inasmuch as it is supposed that, once the sheet has been
folded to form the box, at least initially these surfaces will be arranged perpendicularly
to the rest plane of the box. If the box is destined to contain bottles, it can for
example rest on the lateral surface 4 so that the bottles lie horizontally arranged.
The sheet further comprises at least two longitudinal fold lines, 6, 7, to which a
plurality of flaps are connected, indicated by 2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, which
are foldable and superposable to define, by means of glue spots between the flaps,
two opposite bottom surfaces 8, 9.
[0010] A further flap 2c is connected to the lateral surface 2, the function of which will
be described herein below.
[0011] The cut sheet shown in figure 2 exhibits the following characteristics.
[0012] The internal folds 3a, 3b, 5a, 5b are of a greater height than the external folds
2a, 2b, 4a, 4b. This height corresponds to about a half of the width of the lateral
surfaces 2 and 4.
[0013] The fold 2c has a greater width than normal RSC type boxes, for example the width
of fold 2c can be the same as the height of the external flaps 2a, 2b, 4a, 4b.
[0014] During assembly of the box a fold is made in the base sheet along two transversal
lines, for example lines 23 and 45, and glue is deposited on the flap 2c externally
of the lateral surface 5. The gluing operation must be carried out preferably only
in proximity of the fold line 22. The box at this stage is basically flat, as can
be seen in figure 2a, with the lateral surfaces 2 and 5 in contact with the lateral
surfaces 3 and 4.
[0015] In order to proceed to the packing of the products, the box is opened out, with the
lateral surfaces being distanced so as to obtain a tubular element having a rectangular
section. The products are packed, normally in a vertical position, by inserting them
through one of the two openings. The products may be kept from direction contact with
one another by use of separators.
[0016] To close and seal the box, the base surfaces 8 and 9 are assembled, not necessarily
in that order. The surface 8 is assembled by sequentially folding the internal flaps
3a, 5a, and thereafter the external flaps 2a, 4a, after laying some glue. Similarly
the surface 9 is assembled by sequentially folding the internal flaps 3b, 5b, and
thereafter the external flaps 2b and 4b, after laying some glue.
[0017] To open the box, it is sufficient to lift and break the glue holding the flaps 2a,
2b, 2c. The lateral surface 2 can be rotated about the line 23, which is in fact an
edge of the lateral surface 2, from a position of closure or reclosure, and an open
position, in which it is distanced from the box 1, enabling access to the inside of
the box 1. The surface 2 is in effect a reclosable cover of the box 2. A user, once
the box 1 has been opened by breaking the layer of glue, can reclose the box 1 by
slightly inwardly folding the flaps 2a, 2b, 2c and 2d and inserting them in the box.
The flaps 2a, 2b, 2c further exhibit a tapered edge with a decreasing width in a direction
away from respective fold lines thereof; this is to facilitate folding of the flaps
2a, 2b and 2c and insertion thereof into the box 1 to achieve the re-closed position.
[0018] To facilitate first opening of the box 1, the flaps 2a, 2b, 2c are glued in a zone
which is close to the respective fold lines 6, 7, 22. In this way the user will find
it easy to raise a flap and exert sufficient traction thereon to overcome the resistance
of the various glue spots.
