Technical Field
[0001] The present invention relates to a rigid packet with a hinged lid.
[0002] In particular, the invention relates to a rigid packet of hinge-lid type fashioned
from a flat precreased blank of cardboard or similar material.
[0003] The present invention finds application to advantage in the manufacture of cigarette
packets, the field to which reference is made explicitly in the following specification,
albeit implying no limitation, but could be applied likewise in the manufacture of
cartons or packs designed to contain a plurality of packets of cigarettes.
Background Art
[0004] Rigid packets of the type in question, that is to say packets of parallelepiped geometry
typically rectangular in section, present certain drawbacks deriving from a shape
not readily adaptable to the human anatomy, and from the fact that the side walls
constituting the flanks of the packet are somewhat lacking in rigidity and can buckle
easily. This type of drawback is aggravated further by the fact that the flanks are
subjected to the heaviest stresses, oriented in a direction parallel to the two larger
side faces when the packet is gripped during use, and in particular when the packet
is opened for the first time.
[0005] Such conventional packets of rectangular section are intended exclusively to contain
groups of cigarettes formed by two or more layers arranged parallel to the two larger
side faces, of which the innermost layer or layers will present a number of cigarettes
greater or less than that of the two outermost layers.
[0006] It is known from document DE 36 24 345 another type of packet which is made of cardboard
and formed from a substantially cuboid container with a hinged lid in the form of
the so-called hinged-lid packs, in which a releasable and reclosable, positive-locking
closure is formed between the hinged lid and a frame (8) inserted in the container
[0007] The object of the present invention is to provide a rigid hinge-lid packet that will
be unaffected by the drawbacks described above.
[0008] A further object of the invention is to provide a rigid packet of hinge-lid type
requiring a quantity of cardboard for its manufacture less than that needed for a
similarly proportioned parallelepiped packet of perfectly rectangular section.
Disclosure of the Invention
[0009] The stated object is realized according to the present invention as disclosed in
claim 1.
[0010] Further, preferred embodiments of the invention are disclosed in dependent claims
2 to 12.
[0011] The invention will now be described in detail, by way of example, with the aid of
the accompanying drawings, in which:
- figure 1 illustrates a preferred embodiment of the packet according to the present
invention, viewed in perspective from the front and shown in a closed configuration;
- figure 2 shows the packet of figure 1 in the open configuration, viewed in perspective
from the front;
- figure 3 shows the packet of figure 1 in the closed configuration, viewed in perspective
from the rear;
- figures 4 and 5 show the packet of figure 1 viewed in plan from above and from beneath,
respectively;
- figures 6, 7, 10 and 12 illustrate four different types of diecut blank utilized in
manufacturing the packet of figure 1;
- figure 8 illustrates the packet of figure 1 in a version designed to contain a particular
group of cigarettes, viewed in cross section;
- figure 9 illustrates a portion of the blank used to manufacture the packet of figure
1, shown in a further embodiment;
- figures 11 and 13 are plan views of cigarette packets obtainable respectively from
the blank of figure 10 and from the blank of figure 12.
[0012] With reference to figures 1 to 5 of the drawings, 1 denotes a packet, in its entirety,
containing a group of cigarettes 2 arranged in layers; in the example of figure 2
there are three such layers, of which an intermediate layer has one cigarette 2 less
than the two outermost layers.
[0013] The packet 1 comprises a container 3 of cupped appearance with an open top end, denoted
4, and a lid 5 likewise of cupped appearance hinged to the container 3 and rotatable
thus relative to the container 3 between an open position and a closed position in
which the top end 4 is concealed.
[0014] With the lid 5 occupying the closed position, the packet 1 assumes the appearance
of a substantially rectangular parallelepiped compassed by a front face 6 and a rear
face 7 parallel one with another, two flank faces 8 substantially parallel one with
another and presenting a convex profile, disposed substantially perpendicular to the
front and rear faces 6 and 7 and joined to these same faces 6 and 7 along respective
sharp corner edges 9, also a top end face 10 and a bottom end face 11 parallel one
with another and perpendicular to the remaining four faces 6, 7 and 8.
[0015] Each flank face 8 comprises a flat central portion 12 of substantially rectangular
outline, delimited at the top by a rectilinear central portion 13 presented by one
shorter side 14 of the top end face 10, and delimited at the bottom by a rectilinear
central portion 15 presented by one shorter side 16 of the bottom end face 11; the
top and bottom rectilinear central portions 13 and 15 are identical one to another.
Each flank face 8 further comprises two longitudinal lateral bands 17 located one
on each side of the central portion 12, between the central portion 12 and the relative
corner edge 9. Each band 17 is rendered pliable internally by longitudinal crease
lines 18, so as to assume a curved profile with the concave face directed inwards,
and presents a top edge offered to a curved portion 19 presented by the shorter side
14 of the top end face 10, and a bottom edge offered to a curved portion 20 presented
by the shorter side 16 of the bottom end face 11; the top and bottom curved portions
19 and 20 are identical one to another.
[0016] In the light of the foregoing it will be evident, as clearly discernible from figures
4 and 5, that the distance between the central portions 12 of the flank faces 8 is
greater than the corresponding distance between the corner edges 9.
[0017] The front, rear and flank faces 6, 7 and 8 each include an upper portion denoted
by the suffix "a", coinciding with a relative face of the lid 5, and a lower portion
denoted by the suffix "b" coinciding with a relative face of the container 3, whilst
the top end face 10 coincides with the top of the lid 5 and the bottom end face 11
with the bottom of the container 3.
[0018] With the lid 5 occupying the closed position, the three upper portions 6a, 7a and
8a lie with the respective free edges 21, 22 and 23 offered to the free edges 24,
25 and 26 of the lower portions 6b, 7b and 7b; more exactly, the edge 22 presented
by the rear face 7a of the lid 5 is joined permanently to the edge 25 presented by
the rear face 7b of the container 3, the two combining to create a hinge 27 extending
transversely between two corner edges 9, about which the lid 5 is rotatable between
the open and closed positions.
[0019] Lastly, the rigid packet 1 comprises a stiffening frame 28 of U-profile projecting
partially beyond the open top end 4, composed of a breast piece 29 rigidly associated
with the inside of the front face 6, and, connected to the breast piece 29, two side
pieces 30 each rigidly associated which the inside of a relative flank face 8.
[0020] Each such side piece 30 presents a flat central portion 31 destined to adhere to
the respective inside surface of the flat central portion 12 presented by the relative
flank face 8 of the packet 1, and two respective precreased lateral bands 32 of curved
profile destined to adhere in part to the inside surfaces of the lateral bands 17
presented by the flank face 8. The flat central portions 31 of the side pieces 30
are connected by the lateral bands 32 to the breast piece 29 of the frame 28 by way
of respective sharp corner edges 33 coinciding with the corner edges 9 of the front
face 6.
[0021] Each lateral band 32 is rendered pliable by a respective plurality of longitudinal
crease lines, and each corner edge 33 presents a longitudinal slot 34 serving in conventional
manner to create a respective lip 35 positioned to interact with an internal surface
of the lid 5 in such a way as to hold the selfsame lid 5 in the closed position. Finally,
the breast piece 29 of the frame 28 presents a central cutaway portion 36 directed
toward the lid 5.
[0022] With reference to figures 6 and 7, the packet 1 is fashioned preferably from a flat
diecut blank 37 of substantially elongated rectangular outline, of which the parts
are denoted using the same numbers, primed, as those used to indicate the corresponding
parts of the erected packet 1.
[0023] The blank 37 is referable to a predominating longitudinal axis 38 of symmetry and
presents two crease lines 39 and 40 disposed one on either side of the axis 38, extending
parallel to the axis 38 and dividing the blank 37 into three longitudinal sectors
41, 42 and 43 lying side by side. The three sectors 41, 42 and 43 are crossed by a
plurality of crease lines transverse to the axis 38 and denoted by the numbers 44
to 49.
[0024] The middle sector 42 is divided by the transverse crease lines 44 to 49 into: a panel
6a' positioned between the lines denoted 44 and 45; a panel 10' between lines 45 and
46; a panel 7a' between lines 46 and 47; a panel 7b' between lines 47 and 48; a panel
11' between lines 48 and 49, substantially identical to the panel denoted 10'; and
an end panel 6b' joined to the panel denoted 11'.
[0025] The blank 37 further comprises a plurality of lateral wings 50, 51, 52 and 53 joined
in pairs along the longitudinal crease lines 39 and 40 to the outer edges of the panels
6a', 7a', 7b' and 6b', respectively, of which the wings denoted 51 carry longitudinal
appendages 54 joined along the transverse crease line denoted 46 and directed toward
the wings denoted 50. Similarly, the wings denoted 52 carry longitudinal appendages
55 joined along the transverse crease line denoted 48 and directed toward the wings
denoted 53.
[0026] The wings 50, 51, 52 and 53 are destined to make up the flank faces 8 of the erected
packet 1, and comprise respective flat central portions 56, 57, 58 and 59 each forming
a part of one respective flat central portion 12 of the flank faces 8; the flat portions
56, 57, 58 and 59 in question present a substantially rectangular appearance and are
of width substantially equal to the length of the rectilinear central portions 13
and 15 presented by the shorter sides 14 and 16 of the end faces.
[0027] Each lateral wing 50, 51, 52 and 53 also presents two respective precreased longitudinal
lateral bands 60, 61, 62 and 63 disposed one on each side of the relative central
portion 56, 57, 58 and 59, one extending adjacent to the relative longitudinal crease
line 39 or 40, the other adjacent to the free outermost longitudinal edge of the wing
50, 51, 52 and 53.
[0028] The transverse dimensions of the lateral bands 60, 61, 62 and 63 are identical one
to another and to the dimensions of the curved portions 19 and 20 presented by the
shorter sides 14 and 16 of the end faces; moreover, the lateral bands 60, 61, 62 and
63 are one and the same as the longitudinal lateral bands 17 of the flank faces 8.
[0029] The panel 6a' first mentioned is also joined along the first transverse crease line
44 to a reinforcing flap 64 of width substantially equal to the width of the selfsame
panel 6a'.
[0030] It will be seen that the essentially rectangular panels 10' and 11' destined to become
the top end face 10 and the bottom end face 11 of the packet 1, respectively, are
fashioned with the respective shorter sides 14' and 16' substantially aligned on the
longitudinal crease lines 39 and 40, convexly profiled and presenting respective rectilinear
central portions 13' and 15' that coincide with the top and bottom rectilinear portions
13 and 15 mentioned previously. Each rectilinear portion 13' and 15' extends at the
opposite ends into two relative curved portions 19' and 20' coinciding with the curved
portions 19 and 20 presented by the shorter sides 14 and 16 of the end faces 10 and
11 when packet 1 is erected.
[0031] In the example of figure 6, the aforementioned appendages 54 and 55 present a transverse
dimension substantially the same as the respective transverse dimensions of the flat
central portions 57 and 58 to which they are joined.
[0032] The hinge 27 coincides with the transverse crease line denoted 47.
[0033] The longer wings 52 and 53 will be bent at right angles to the respective panels
7b' and 6b' with which they are associated. These same panels 6b' and 7b' are then
bent toward one another at right angles to the intermediate panel 11', with the result
that the wings 52 of one pair will overlap the wings 53 of the other pair, causing
the lateral bands 62 and 63 to assume a curved profile relative to the corresponding
central portions 58 and 59 and thus form the flank faces 8b of the container 3. Similarly,
the appendages 55 are bent inwards at right angles to the respective wings 52 and
rotated together with the wings 52 to the point of engaging the inside surface of
the corresponding panel 11', with which they combine to establish the bottom end face
11 of the packet 1.
[0034] In like manner, the shorter wings 50 and 51 are bent at right angles to the respective
panels 6a' and 7a' with which they are associated. The flap 64 is bent double against
the internal surface of the adjoining panel 6a', whereupon the two panels 6a' and
7a' are bent toward one another at right angles to the intermediate panel 10' so that
the wings 50 of one pair ultimately overlap the wings 51 of the other pair, causing
the lateral bands 60 and 61 to assume a curved profile in relation to the central
portions 56 and 57 and thus form the flank faces 8a of the lid 5. Similarly, the appendages
54 are bent inwards at right angles to the respective wings 51 and rotated together
with the wings 51 to the point of engaging the inside surface of the corresponding
panel 10', with which they combine to establish the top end face 10 of the packet
1.
[0035] The two longitudinal lines 39 and 40 are creased more forcibly than the lines generating
the lateral bands 60, 61, 62 and 63, so that when the lateral wings 50, 51, 52 and
53 are bent along these same crease lines 39 and 40, the sharp corner edges 9 of the
packet 1 will be formed decisively and without difficulty.
[0036] It will be seen that the operations of folding the blank 37 as described above are
pertinent only to the container 3 and the lid 5; accordingly, the stiffening frame
28 is prepared preferably by means of separate folding operations and then assembled
with the container 3.
[0037] In the example of figure 7, the appendages 54 and 55 are attached respectively to
the rectilinear central portions 13' presented by the shorter sides 14' and 16' of
the intermediate panels 10' and 11' and exhibit a width dimension, measured parallel
to the longitudinal axis 38, substantially equal to the width dimension, measured
transversely to the longitudinal axis 38, presented by the flat central portions 56,
57, 58 and 59 of the lateral wings 50, 51, 52 and 53.
[0038] The packet 1 in the example of figure 8 is formed in exactly the same way as the
packet 1 illustrated in figures 1, 2 and 3 but serves to accommodate a group of cigarettes
2 comprising four layers, of which the two innermost layers 65 include one cigarette
more than the outermost layers 66.
[0039] The blank 37 illustrated in figure 12 differs from the blanks 37 of figures 6 and
7 in that the wings 50, 51, 52 and 53 have no outer precreased lateral bands 60, 61,
62 and 63. In this instance the plan view of the packet 1 in figure 4 becomes as indicated
in figure 13, where the flank faces 8 of the packet 1 are assembled with overlapping
contact restricted to the flat central portions 12, generated by the flat portions
56 and 58 of the corresponding wings 50 and 53.
[0040] The blank 37 illustrated in figure 10 differs from the blanks 37 of figures 6 and
7 in that just two of the pairs of wings 51 and 53 have no outer precreased lateral
bands 61 and 63, whereas the remaining wings 50 and 52 are identical to those of the
blanks 37 in figures 6 and 7.
[0041] In this instance the plan view of the packet 1 in figure 4 becomes as indicated in
figure 11, where the flank faces 8 of the packet 1 are assembled with overlapping
contact between the flat central portions 12 generated by the flat portions 56 and
58 of the corresponding wings 50 and 53 and between the lateral bands 17 adjacent
to the sharp corner edges 9 of the front face 6.
[0042] Finally, in the example of figure 9, each of the appendages 54 and 55 comprises a
substantially rectangular central portion 67 attached to the flat portions 57 and
58 of the corresponding lateral wings 51 and 52, and two lateral portions 68 and 69
located on either side of the central portion 67.
[0043] The lateral portions 68 and 69 are substantially trapezoidal in appearance, and the
respective sides nearer the wings 51 and 52, extending from the line along which the
appendages 54 and 55 are joined to the corresponding flat portions 57 and 58, present
a curved profile identical to that of the curved portions 19' and 20' presented by
the intermediate panels 10' and 11'.
