OBJECT OF THE INVENTION
[0001] The present invention refers to a carrier for cans with a gripping zone.
[0002] The carrier is formed from a panel of compact cardboard.
[0003] The carrier permits a specific number of cans to be held together and transported.
OBJECT OF THE INVENTION
[0004] The present invention refers to a carrier for cans made from compact cardboard, with
a gripping zone for facilitating transport thereof, with the gripping zone in respect
of the arrangement being the key to the invention.
[0005] Various carriers are known in the state of the art such as that described in document
W003004377 which describes a carrier for cans made from corrugated cardboard which connects
a group of cans, the centre of which is provided with two gripping points for transporting
the arrangement.
[0006] The document with publication number
EP0456361 describes a carrier for cans with a handle made from plastic material. It is advisable,
for environmental reasons, to use cardboard in carriers for cans as cardboard is much
easier to recycle. The carrier in this case is technically totally different. The
holding zone is in the centre of the can in a vertical direction and is held due to
the elasticity of the plastic. In contrast, in the present invention, the holding
is made in the neck of the can, in the upper part, and holding is based on pressure
through stretching at the moment of gripping. Given this type of plastic carrier,
in devising a cardboard carrier, several problems need to be resolved, as in the case
of plastic carriers, the cans are connected and held by the middle part or trunk of
the can, and the performance of the plastic when attaching the cans is totally different
from a cardboard carrier.
[0007] The document with publication number
US5310051 also describes a blank for carrying cans which aims to solve the problem of transporting
the arrangement by means of the reinforcement of the central zone which is where the
transport points are situated.
[0008] In all these systems the key factor is how the cans are held during transport, as
the force exercised on the gripping points and the actual transport itself tends to
detach one of the cans from the group.
DESCRIPTION OF THE INVENTION
[0009] This problem is resolved in the present invention by grouping and transporting the
cans by means of compact cardboard blanks which also improves hygiene as the blank
covers the cans.
[0010] When the cans are grouped with cardboard blanks and the support blank is supposed
to support the weight of all the cans and enable them to be carried about, normally
one of the cans becomes detached due to the force supported by the blank and the movement
during transport.
[0011] The problem is resolved in the present invention with a specific configuration of
the blank and an adequate position of the gripping zone in the blank.
[0012] The type of material used in the present invention is compact cardboard which has
the resistance required to support the group of cans.
[0013] When cardboard is manufactured, the paste fibres are aligned in parallel in the direction
in which the cardboard blank is moving. In the present invention this characteristic
is used in that the blank in a specific direction is more rigid and stronger.
[0014] An initial aspect of the invention refers to a carrier for cans configured with a
blank which consists of:
- A main area for holding the cans,
- At least two cuts for fixing the cans in the main area arranged facing each other.
- A means of gripping for lifting the arrangement consisting of the cans and the blank,
Where
- The blank is made from compact cardboard with the fibre oriented according to a preferred
direction; and,
- The gripping means is a handle arranged on the side of the blank in such a way that
each connection of the handle with the main area of the blank is extended by means
of a continuous fixation band, ensuring that:
- The cuts for fixing the cans are arranged on either side of the band; and,
- The direction of the oriented fibre in the cardboard blank coincides essentially with
the direction in which the band or bands is/are extended.
[0015] There may be at least two fixation bands in the blank which give rise to two alignments
for the cans.
[0016] A second aspect of the invention of the carrier for cans shows the cuts for fixing
the can outlets such that the blank curves round the outlet of the can when gripping
and transporting in such a way that the internal fixation rims tend to approach each
other, thus pressurising said outlet.
[0017] A third aspect of the invention is that the carrier is provided between the groups
of cuts associated with the fixation bands of the outlets of the cans with one or
more cuts which enable separation of the internal sections of blank arranged round
said fixation cuts of the can outlet.
[0018] In addition, as the present invention is made from cardboard, it is more easily recycled
than plastic products designed for the same purpose.
[0019] Another advantage of this invention is that as it is a blank which is held in the
upper part of the cans, it protects the tops of the cans which is the area drunk from.
This surface may also be used for placing product advertising.
DESCRIPTION OF THE DRAWINGS
[0020] The present descriptive report is supplemented by a series of drawings, illustrative
of a preferred embodiment but not, however, restricting the invention in any way.
[0021] Figure 1 shows a side view of the blank which is the subject of the invention.
[0022] Figure 2 shows a side view of the blank which is the object of the invention with
the gripping zone in a side facing that of figure 1.
PREFERRED EMBODIMENT OF THE INVENTION
[0023] In a preferred embodiment of the invention the carrier for cans is constituted on
the basis of the blank shown in figure 1.
[0024] This blank is designed to group and transport six cans in two rows.
[0025] In the carrier which is the subject of the invention, the cans are inserted in the
blank through the top. The blank is provided with semi-circular facing cuts (1) for
each can.
[0026] The gripping means consists of a handle (2)arranged on the side of the blank in such
a way that each connection of the handle with the main area of the blank is extended
by means of a continuous band (3), in this case two bands (3).
The upper part of the cans show a narrowed zone and they are finished in the upper
part in a thickened ring. The narrowed zone is housed in the semi-circular cuts (1),
the upper circular zone of the can is covered.
[0027] The design of the cuts enables the cans to be held by their upper rim, and the upper
part of the can is protected.
[0028] In order to facilitate displacement of the bands (3) in contact with the semi-circular
cuts (1) on each of said semi-circular cuts (1) and on one of its ends an oblique
cut (4) is made.
[0029] Between the semi-circular cuts (1) associated with each band (3) for fixation of
the can outlets, separation cuts (5) are made which permit separation of the internal
sections (6) of the blank arranged round said semi-circular fixation cuts (1) of the
can outlet.
[0030] The separation cuts (5) are essentially longitudinal and the orientation coincides
with the direction of the bands with other transversal cuts (7) being possible in
one or two ends.
[0031] When this report mentions essentially longitudinal cuts the intention is to cover
variations in the procedure for constituting the blank which do not permit perfectly
longitudinal cuts.
[0032] The essential nature of this invention is not altered in any way by variations in
materials, form, shape and arrangement of the component elements which are described
in a manner which is in no way restrictive but which is sufficient for an expert to
proceed to its reproduction.
