Claims
We claim:
1. A hinged lid packet with a lid portion hinged to a body portion,
the body portion comprising a front wall including an integral
recessed panel extending upwardly from the front wall, a rear wall,
a pair of side walls each formed by an inner flap and by an outer
flap, one of said flaps extending from the rear wall and the other
of said flaps extending from the front wall, the recessed panel
being narrower than the front wall and being recessed towards the
interior of the packet and disposed substantially parallel to said
front wall so that when the packet is closed the panel lies wholly
within the lid portion, and a pair of side flaps extending from the
sides of the recessed panel in a direction parallel to the
respective side walls, the lower part of each side flap being
sandwiched between the inner and outer flaps of the respective side
walls.
2. A hinged lid packet as claimed in claim 1 in which the inner
flaps are higher than the outer flaps, and in which the top portion
of each inner flap is recessed inwardly parallel to its bottom
portion so that the side flaps are sandwiched substantially in
alignment with said bottom portion of the inner flaps.
3. A hinged lid packet as claimed in claim 1 in which the lower
sandwiched parts of the side flaps are secured to the inner and
outer flaps by adhesive.
4. A one-piece blank for forming a hinged lid packet as claimed in
claim 1.
5. A hinged lid packet as claimed in claim 1 in which the upper
edges of the side walls are inclined so that the height of the side
walls is greater at the rear wall than at the front wall.
6. A hinged lid packet as claimed in claim 1 wherein at least said
body portion is constructed from a one-piece blank.
7. A hinged lid packet with a lid portion hinged to a body portion,
the body portion comprising a front wall; a rear wall; a pair of
side walls each formed by an inner flap extending from the rear
wall and by an outer flap extending from the front wall; a recessed
panel extending upwardly from the front wall, the panel being
narrower than the front wall and being recessed inwardly parallel
thereto so that when the packet is closed the panel lies wholly
within the lid portion; and a pair of side flaps extending from the
sides of the panel, each side flap being partly sandwiched between
the inner and outer flaps of the side walls, the inner flaps being
higher than the outer flaps, and the top portion of each inner flap
being deformed inwardly parallel to its bottom portion so that the
side flaps are sandwiched substantially in alignment with said
bottom portion of the inner flaps.
Description
This invention relates to packets, for example for cigarettes or
the like, and is particularly concerned with packets known as
hinged lid packets.
Hinged lid packets are conventionally made from two cardboard
blanks, one blank for forming the body and lid which are joined by
an integral hinge, and another blank for forming an insert or inner
frame which is assembled to the inside of the front and side walls
of the body and projects above these walls. The insert forms a seal
between the lid and body when the packet is closed and, more
importantly, it retains the packet closed by frictionally engaging
the inside of the front wall of the lid. However unless the insert
is made substantially of the full depth of the packet, which would
consume an unnecessary amount of cardboard, it is difficult to
secure the insert to the body at the correct height to achieve a
satisfactory engagement with the lid. A further disadvantage is
that additional machinery is required for making a separate blank
for the insert, and for assembling the insert in the body of the
packet.
Proposals have been made to produce a packet having an insert
integral with, and made from the same blank as, the body and
lid.
According to the present invention there is provided a hinged lid
packet with a lid portion hinged to a body portion, the body
portion comprising a front wall, a rear wall, a pair of side walls
each formed by an inner flap extending from the rear wall and by an
outer flap extending from the front wall, a recessed panel
extending upwardly from the front wall, the panel being narrower
than the front wall and being deformed inwardly parallel thereto so
that when the packet is closed the panel lies wholly within the lid
portion, and a pair of side flaps extending from the sides of the
panel, each side flap being partly sandwiched between the inner and
outer flaps of the side walls.
The inner flap may be higher than the outer flap, the top portion
of the inner flap being deformed inwardly parallel to its bottom
portion so that the side flaps are sandwiched substantially in
alignment with said bottom position of the inner flaps. The
sandwiched parts of the side flaps are preferably secured to the
inner and outer flaps by adhesive.
The invention will now be described, by way of example, with
reference to the accompanying drawings in which:
FIG. 1 in a perspective view which shows a packet according to the
invention, and
FIG. 2 is a plan view, to a smaller scale, of the blank from which
the packet is made.
The packet shown in FIG. 1 is produced from the single cardboard
blank shown in FIG. 2 and comprises a lid L integrally hinged along
a line H to a body B.
The lid L includes a rear wall 10 extending from the hinged line H,
a top panel 11, a front wall 12, and a reinforcing panel 13 which
is folded back and secured by adhesive to the inside surface of the
front wall 12. Inner and outer flaps 14 and 15 extend from each
side of rear wall 10 and the front wall 12 respectively, and are
secured together to form the side walls of the lid. A further flap
16 extends from each of the flaps 14 and is secured inside the top
panel 11.
The body B comprises a rear wall 20, a base 21, and a front wall
22. The side walls of the body are formed by inner flaps 23
extending from each side of the rear wall 20 and by outer flaps 24
extending from each side of the front wall 22. A flap 25 extending
from each inner flap 23 is secured to the inside of the base 21.
The top portion 26 of each inner flap 23, as viewed in the upright
packet of FIG. 1, is deformed inwardly parallel to the bottom
portion by an amount corresponding to the thickness of the
cardboard blank. Small cut-outs 27 are provided at the outer edges
of the deformed portions 26.
A recessed panel 30 extends upwards from the front wall 22, and is
likewise deformed inwardly parallel to the wall 22 by the thickness
of the blank. The width of the recessed panel 30, defined by lines
31, is smaller than that of the front wall 22 and is shown slightly
exaggerated in the drawings.
Joined to each side of panel 30 along corner 31 is a side flap 32,
which is approximately of the same width as the inner and outer
flaps 23 and 24. As a result of the recessing of panel 30 and the
inclination of the lower edges 33 of the flap 32, the lower edges
33 come below the upper edges of the outer flaps 24 in the erect
packet.
The insides of the lower edges rest against the deformed portions
26 so that the flaps 32 are in alignment with the bottom portions
of inner flaps 23. Thus the flaps 32 are partly sandwich between
the upper portions of the inner and outer flaps 23 and 24 to which
they are secured by adhesive. The cut-outs 27 serve to accommodate
the inside corners of the recessed panel 30 at the lower ends of
the lines 31.
By having the recessed panel 30 integral with the body, the corners
above the lines 31 (which serve to engage the inside of the front
wall of the lid to keep the packet closed) can be produced more
accurately to the correct height.
Certain other features shown in FIGS. 1 and 2 are conventional and
will therefore only be described briefly.
Short inclined slits 34 are provided at the ends of the hinge line
H, to facilitate opening of the lid L; the corners 35 of the flaps
32 are inwardly bent to guide the sides 14 and 15 over the flaps 32
when closing the lid L; and ears 36 are formed at the corner edges
31 to frictionally engage the sides of the lid and thus assist in
maintaining the packet closed.
The shape of the cut-out in the recessed panel 30 is also
conventional, and provides access to cigarettes (not shown) which
are contained in the packet.
It will be understood that the reinforcing panel 13 need not be
rectangular, but may instead be shaped to coincide with the cut-out
in the panel 30, so that less material is wasted in the production
of the blanks.
