Description
~ 33 _ 1 _ This invention relates to packages or boxes of the hinged lid type, especially packages or boxes for cigarettes, and to blanks from which such packages or boxes may be formed.
Hinged lid packages for cigarettes have conventionally been manufactured from two cardboard blanks. One blank forms the body and lid whlch are joined by an integral hinge, and the other forms an insert or inner frame which is glued to the inside of the front and side walls of the body and projects above these walls to provide a collar. The collar serves to provide a seal between the lid and body when the pack-age is closed, and to frictionally engage the inside of the front wall of the lid to retain the package closed.
In packaging of cigarettes the manufacturer obtains the first blank, which is relatively complex in structure, from a first supplier, and cuts the second blank, which is relatively simple in structure, himself.
The material for the second blank is obtained as a roll from a second supplier, and is die cut to provide the required insert blanks.
~Dr-~
This procedure has several disadvantages:
The cardboard of the second blank is different from the cardboard of the first blank. This means that a uniform appearance is not achieved and it is not possible to have an identical colour match for the body and lld on the one hand, and the collar on the other.
The use of a separate blank for the insert also means that it is not possible to pre-print display material or information on the collar that will agree in appearance or complement display material or information on the ~ody and lid.
The dies for cutting the second blank have a limited life and must be replaced periodically.
Inevitably poor quality inserts are produced towards the end of the die life, as well as inserts of such inferior quality that they cannot be used.
The use of two blanXs results in the upper edge of -the front wall of the body being a raw or expose~ edge, which results in a less acceptable and less marXetable product.
It should be recognized that an attractive, even expensive, appearance is an important marketing feature in the' sale of cigarettes, particularly in the high priced market. Packets are produced in attractive colours, sometimes with a gold, silver or platinum metallic 3 ~ 3~
sheen, with handsome crests and raised or embossed lettering.
In order to satisfy the cigarette manu-facturer the packet manufacturer is required to supply blanks which will form a packet of a slim attractive appearance. In particular the lid should close firmly to provide a rectangular cuboid with smooth walls. In other words the lid should fit snugly against the upper edges of-the front and side walls of the body so that there are no unsightly gaps and the front and side walls of the closed packet appear to be continuous, with just a line identifying the mating edges of the lid and body.
The importance of a smooth front wall formed from the front wall of the lid and the front wall of the body has become particularly important in Canada. When a packet of cigarettes is assembled by the cigarette manu-facturer, it is finally wrapped in a transparent plastic foil and a tear strip is applied.
The tear strip is applied by the cigarette manufactur~r around the packet so as to conceal the line connection on the front wall between the lid and the body. This location is selected since the appearance of the packet is enhanced by concealing the line connection on the front wall, and in addition this area of the packet is free from display or information material, so ~ 3 that locating the tear strip in this area avoids obscuring such material.
In the final operation an excise stamp is applied to show that the required duty has been paid to the Government.
In ~anada this excise-stamp forms part of the tear strip. The tear strip material is provided as a roll of a predetermined length to provide tear strips for a predetermined number of packets; the excise 1~ tax having been paid in advance, having regard to the length of the roll, by the cigarette manufacturer.
In order for a tear strip to be supplied from the roll of tear strip material, and applied by machine around the packet at the desired location, it is especially important that the walls of the packet, particularly in the area of application to the packet, be srnooth. If the lid is offset inwardly or outwardly of the body, it is difficult to properly apply the tear strip. Indeed the strip may be damaged and may thus need to be discarded, even though excise duty has been prepaid for each unit length of tear strip.
The different requirements of the cigarette manufacturers thus place exacting demands on the packet manufacturer. The packet manufacturin~
industry is highly competitive and even apparently ~ 3 minor advances can have a significant affect on the manufacturer's ability to obtain orders for his packets.
Another important demand that cigarette manufact rer's make is that new packet designs ~e adapted to existing folding and assembly equipment in their premises~ Clearly a cigarette manufacturer will be reluctant ~o place orders for a new packet design, however attractive, if the new design necessitates replacement of existing folding and assembly equipment.
Prior proposals have been made for packets of this general type, which may be formed from a single blank. In this regard there may be mentioned U.S.
Patents 3,979,047; 4,196,842; 4,251,022 and 4,267,958 all assigned to Focke & Co. of Verden, Federal Republic of Germany. There may also be mentioned U.S. Patent 3,874,581 and Canadian Patent -1,059,477 both assigned to Molins Limited o London, England, and Canadian Patent 1,114,341 assigned to British-American Tobacco Company Limited of England.
The first two Patentees are both machine or equipment manufacturers. In designin~ packets their basic objective is to sell new machines. None of these packet designs has found commercial acceptance, at least not in North America.
r As exemplary of a hinged lid packet in which the collar is formed from a separate blank there may be mentioned Canadian Patent 1,056,783 assigned to Focke &
Co .
These prior single blank designs all have the disadvantage that they are not suited to folding and assembly on equipment designed for the folding and assembly of the separate blanks designs. In addition the individual designs have other disadvantages.
The Molins Patents and U.S. Patent 4,196,842 require deformation of the material of the collar portion to d1splace the collar inwardly of the front wall of the body. This is a difficult operation to reproduce consistently; consequently, variation occurs i-n the verysmall offset spacing between the collar and the front wall in different packets. If this spacing does not correspond exactly to the thickness of the mating front and side walls of the lid, the lid will not be lpcated so as to form smooth front and side walls in the assembled packet.
U.S. Patent 3,979,047 particularly requires that the collar be connected not only to the front wall of the body but also to the side walls forming flaps of the front wall, so as to form an inwardly off-set collar in the æone of the front and side walls of the ~.~ r,,i~D
packet. In achieving this, relief apertures are formed in the connection between the collar and the body.
U.S. Patent 4,267,958 employs connecting bridges between the collar and the front wall.
U.S. Patent 4,251,022 is more especially concerned with packets which require permanent moulding of some of the flaps of the formed blanks by embossing techniques.
Still another important requirement is to provide a tamper evident packet. In other words the packet should have a structure or appearance whereby the customer will be able to determine if the packet has been previously opened and the contents removed or tampered with, when he first opens it.
A tamper evident feature has become especially important recently as a result of activities of criminal elements~
There have been several prior proposals for tamper evident packets. In this regard there may be mentioned U.S. Patents 4,314,643 ; 4,113,104; 3,893,614 and 4,284,197. The first three mentioned U.S. Patents have the disadvantage that the tamperproof or tamper evident feature produces an unsightly appearance after the packet has been opened.
In U.S. Patents 4,314,643 and 3,893,614 adhesion spots and possibly a torn surface will remain on the front wall after opening the packet.
In U.S. Patent 4,113,104, a portion of the front wall of the lid remains adhered to the front wall of the packet.
In U.S. Patent 4,284,197 part of the front wall of the packet is ripped out leaving a pattern of projections intended to mate with corresponding recesses on the ripped out section which is adhered to the lid. The ripped out section detracts from the appearance of the front wall of the packet in the open configuration and if the projections and recesses do not match exactly, the lid will not close snugly and firmly to provide a rectangular cuboid with smooth walls.
The present invention particularly seeks to provide a hinged lid packet having a tamper evident feature which does not damage or produce an unsightly appearance in the front wall of the packet in the open or closed conf`iguration.
The present invention seeks in a particular embodiment, to provide such a hinged lid packet having a tamper evident feature and formed from a single blank, and which can be folded and assembled from such single blank on conventional equipment employed in the folding and assembly operations to produce such a packet from separate blanks.
~ ~ r,,~S~
In a further specific embodiment the invention seeks to provide a hinged lid packet having a tamper evident feature and formed from a single blank, in which in the closed configuration the lid is flush with the body to provide substantially smooth front and side walls.
In accordance with the invention there is provided a hinged lid packet comprising a lid portion hinged to a body portion, said lid portion mating with said body portion to form a cuboid with sub-stantially smooth surfaces, a collar portion within said packet, extending from said body portion into said lid portion, a panel in said collar portion secured to an inner face of said lid portion, the panel being substantially separated from the collar portion and removably connected to the collar portion at spaced apart frangible connections.
When the packet is hingedly opened the frang-ible connections are broken and the panel remains secured to the lid to leave an access slot in the collar portion.
In particular the panel is substantially separated from the collar portion by a plurality of elongated slits; the elongated slits being separated by the frangible connections. In this way the elongated slits and the frangible connections form a frangible line between the collar portion and the panel, and breaking the frangible connections leaves a clean smooth edge in the collar, defining an access slot.
In particular the panel is formed in the collar portion by the elongated slits which pass com-pletely through the collar portion; the frangible connecting elements which separate the slits have the form of short tabs or links and serve to connect the panel to the~collar portion for ready removal there-from. The frangible connecting elements are of astrength and dimension such that when the lid of the packet is hingedly opened the connecting elements are readily broken and the panel remains secured to the - lid portion and is cleanly removed.
The panel is suitably secured to the inner face of the lid portion by an adhesive, which provides an attachment of the panel to the lid portion significantly stronger than the weak attachment of the panel to the collar portion, by the frangible connecting elements.
Removal of the panel leaves a recess in the collar portion defined by a generally clean edge corresponding to the pattern of elongated slits.
The invention also provides a unitary blank for such a packet.
- -The invention is illustrated in particular and preferred embodiments by reference to the accompanying drawings in which:
FIGURE 1 is a perspective view which shows a packet according to the invention after having been opened;
FIGURE 2 is a side view showing the packet of Figure 1 in a closed configuration;
FIGURE 3 is a plan view of the blank, inside facing up from which the packet of Figures 1 and 2 is made-FIGURE 4 is a perspective view showing the packet of Figure 1 partially assembled from the blank of Figure 3; and FIGURE 5 is a view similar to Figure 1 show-ing the closed packet wrapped in a transparent foil with a tear strip having an excise stamp.
With particular reference to Figures 1 and 4, a hinged lid packet 10 comprises a body 12, a lid 14 and a collar 16 disposed inwardly of body 12.
Lid 14 is hingedly connected to body 12 along a hinge line 18.
Body 12 includes upper side edges 20 and 22 and a front folded edge 24.
r~
~ 12 -Lid 14 includes side edges 26 and 28 and a lid folded edge 30.
Ears 32 extend from collar 16.
With particular reference to Figure 4, a removable panel 200 is connected to collar 16. With particular reference to Figure 1 the panel 200 is adhered to the inside of the lid 14 after packet 10 has been opened, and there is no damage to the collar 16 or body 12.
In the closed configuration shown in Figure
Hinged lid packages for cigarettes have conventionally been manufactured from two cardboard blanks. One blank forms the body and lid whlch are joined by an integral hinge, and the other forms an insert or inner frame which is glued to the inside of the front and side walls of the body and projects above these walls to provide a collar.

A crease and fold line 160 is formed between front wall panel-150 an~ outer side wall flap 156;
and a crease and fold line 162 is formed between front wall panel 150 and outer side wall flap 158.
A cr~ase and fold line 130 is formed between reinforcing panel 64 and front wall panel 150. Crease and fold line 130 forms the folded edge 30 of packet 10 .
A crease and fold line 157 is formed between front wall panel 150 and top wall panel 154; and a crease and fold line 159 is formed between top wall panel 154 and rear wall panel 152.
Crease and fold lines 161 are formed between top and side flaps 66 and 70, respectively, and top and side flaps 68 and 72, respectively.
Crease and fold lines 163 are formed between side flaps 70 and 72 and rear wall 52.
Arrowhead or V-shaped slots 165 are defined between lid-forming portion 114 and body-forming portion 112.
- 17 ~
Each arrowhead slot 165 includes a curved head 167 spaced outwardly of the adjacent crease and fold line 129, with a short cut 169 extending from curved head 167 to the crease and fold line 118 which forms hinge line 18.
Side flaps 70 and 72 each have an exposed edge 171 defining one side of slot 165.
Each exposed edge 171 includes an inclined edge 173 which diverges outwardly relative to the opposed inclined edge 120b, 122b, respectively.
Inclined edge 173 terminates in a sub-stantially horizontal edge 175.
Collar-forming portion 116 includes a front wall panel 180, a spacer panel 181 and side wall panels 182 and 184.
Removable panel 350 is connected to collar-forming portion 116 by frangible connections 352 which are separated by elongated slits 354 along a frangible line 356.
Inclined upper edges 187 of collar-forming portion 116 define the inclined side and front edges 98 and 100 of collar 116.
Perforated fold lines 188 and 190 between front wall panel 180 and side wall panels 182 and 184, respectively, define the lines 88 and 90 of collar 16.
A perforated fold line 191 is formed between panels 180 and 181.
Side wall panels 182 and 184 have inclined lower edges 193 and 195.
Large slots 197 and 199 are defined between inclined lower edges 193 and 195 and 120a and 122a respectively.
The folding along perforated fold line 191 and crease and fold line 124 produces a so-called Z-fold formed by front wall 34, spacer panel 181 and front wall 80 of collar 16, fold 24 and the fold at line 191.
With further reference to Figure 5, a sealed packet 10 has a transparent foil wrapping -200 and a tear strip 202 having a tear tab 204.
Tear strip 202 conseals line 33 on the front face of carton 10. As currently used in Canada the tear strip 202 bears the legend CIGARETTES.CANADA.-CIGARETTES.DUTY PAID.DROIT ACQUIT., which legend is repeated along the strip. Location of the tear strip 202 along line 33 leaves the remaining large surface areas of the packet 10, bearing decorative and information material, unobstructed.
In the assembly of the carton 10, the blank 110 is delivered in a horizontal path. Reinforcing panel 64 is folded about crease and fold line 130 and is adhered to the inside face of front wall panel 150, and collar-forming portion 116 is folded about perforated fold line 191 and crease and fold line 124.
In this latter operation access is required from the side and the large slots 197 and 199 facilitates handling and folding by existing equip-ment employed in assembly of conventional two-blank designs.
Spacer panel 181 is glued to the interior face of front wall panel 134 of body forming portion 112.
In subsequent operations rear side wall flaps 140b and 142b are folded about crease and fold lines 120 and base flaps 125 are folded about crease and fold lines 131.
Base wall panel 138 is folded about crease and fold lines 133a and 133b, respectively.
Front wall flaps 140a and 142a are folded about crease and fold lines 127 and the inside faces of flaps 140a and 142a are glued to the outside faces of flaps 140b and 142b. In this way the front side wall flaps form the outer surfaces of side walls 40 and 42 and smooth corners are formed at fold lines 44 and 46 on the front face of the packet 10.
With the folding of front side wall flaps 140a and 142a about crease and fold lines 127, side walls 82 and 84 of collar 16 are formed by folding side wall panels 182 and 184 about perforated fold lines 188 and 190. The side walls 82 and 84 are disposed inwardly of flaps 140b and 142b.
In this way the body 12 with the collar 16 and panel 250 spaced inwardly thereof is formed.
In the assembly of lid 14 top flaps 66 and 68 are folded about crease and fold lines 161 and side flaps 70 and 72 are folded about crease and fold lines 163, and top wall panel 154 is folded ~bout crease and fold line 159. In this way top flaps 66 and 68 are disposed on top wall panel 154 to form top wall 54.
Front wall panel 150 is folded about crease and fold line 157 and outer side wall flaps 156 and 158 are folded about crease and fold lines 160 and 162 respectively and the outer faces of side flaps 70 and 72 are glued to the inner faces of side flaps 156 and 158 to form side walls 56 and 58.
- 21 ~
The provision of arrowhead slots 165, results in the exposed edge 171 of side flaps 70 and 72 being spaced inwardly of the side edges 26 and 28 defined by outer flaps 156 and 158. This spacing provides some tolerance in the location of flaps 70 and 72 against flaps 156 and 158 for adhesion. Thus even if top flaps 66 and 68 are slightly spaced from top wall panel 154 when flaps 70 and 72 are adhered to flaps 156 and 158, respectively, the exposed edge 171 of side flaps 70 and 72 is still spaced inwardly of the side edges 26 and 28 so that lid 14 can still be closed to form a cuboid packet 10 with smooth surfaces free of gaps at the juncture of lid 14 and body 12.
The ears 32 formed in the front sides of collar 16 frictionally engage the inside of side walls 56 and 58 thereby assisting in maintaining the packet 10 in the closed configuration.
An assembly of cigarettes, typically wrapped in a metallized paper foil is inserted in the assembled packet.
Adhesive spots 260 are applied to the front face of panel 250, or adhesive spots 262 may be applied to the inwardly directed face of reinforcing panel 64. It is also possible to apply adhesive spots 256 to panel 20 and adhesive spots 258 to panel 64. Lid 14 is closed so that panel 64 and panel 250 are adhered together by adhesive spots 260 and/or 262.
In the closed configuration the horizontal side edges 96 of collar 16 engage the top flaps 66 and 68. The inclination of side edges 98 and front edges 100, on the other hand, facilitates closure of the packet 10 by the effective removal of the .front upper corners of collar 16 which would other-wise engage reinforcing panel 64 during closure such that closure of packet 10 would either crush or deform the upper f`ront corners of collar 16, or the front wall 50 of lid 14 would be deformed so that a smooth front face would not be obtained on packet 10 .
By reference to Figure 3 it will be observed that collar-forming portion 116 has two major panels namely front wall panel 180 and spacer panel 181. In particular spacer panel 181 has a height at least two-thirds the height of front wall panel 180.
~ ,'r~7~3 In addition side wall panels 182 and 184 which are connected to front wall panel 180 along perforated fold lines 188 and 190 respectively, are not connected at all to spacer panel 181 and are spaced from perforated fold line l91o Suitably the spacing of the inclined lower edges 193 and 195 of side wall panels 182 and 184 respectively, from per-forated fold line 191 is at least one-quarter the height of spacer panel 181 so as to ensure that relatively large slots 197 and 199 are formed to facilitate side entry of conventional package assembly equipment employed with two-blank designs, in assembly.
The provision of panels 180 and 181 both of major surface area with the side panels 182 and 184 connected to panel 180 and spaced a significant distance from fold 1-91 represents a significant difference over the single blank designs described in the prior patents referred to above.
The lower edge 193 and 195 can also be made perpendicular to fold lines 188 and 190, however, this diminishes the si~e of slots 197 and 199, and in particular the mouth of slo~ 197 formed at the outer opposed corners of panel 182 and flap 140a, and the mouth of slot 19 formed at the outer opposed corners of panel 182 and flap 142a, is then much narrower and this hinders side access of the package assembly equipment.
By forming edges 193 and 195 parallel to the opposite edges 120 and 122a, respectively, of side wall flaps 140a and 142a, the large slots 197 and 199 are formed with a wide mouth for access of the equipment.
In blank 11~, the width of rear wall panel 136 of body-forming portion 112 is slightly narrower than the width of front wall panel 134. More especially in forming a substantially cuboid package 10,-the width of rear wall panel 136 plus four times the thickness of the blank 110 (i.e., the thickness of side walls 40 and 42 formed from flaps 140a and 140b and 142a and 142b respectively) equals the width of front wall panel 134.
` The outer side edges of lid forming-portion 114 and body-formirlg portion 11~ of blank 110 are substantially in line or form a straight line; and the outer side edges of collar-forming portion 116 are spaced slightly inwardly or are offset inwardly with respect to such line. In other words the outer edge of side wall panel 182 of collar-forming portion 116 is spaced slightly inwardly of a straight line formed by the outer edge of front side wall - 25 ~
flap 140a, base flap 125, rear side wall flap 140b, side flap 70, top flap 66 and outer side wall flap 156.
The outer edge of side wall panel 184 has a similar relationshiP with the flaps of body-forming portion llZ and lid-forming portion 114 on the opposed side of` blank 110.
Thus a substantially cuboid packet of the hinged lid type, with smooth front and side walls, is provided from a single blank using equipment already employed by cigarette packing companies for separate blank designs.
As can be seen in Figure 5 a transparent foil wrapping 200 can be formed around such a package in a conventional way, and a tear strip 202 indicating that Excise Duty has been pre-paid can be applied along the smooth juncture of the lid and body at the front f`ace of the package 10.
On the other hand, the transparent foil wrapping 200 is not employed in all embodiments.
The use of crease and fold lines in the invention produces relatively curved, smooth corners, whereas the use of perforated fold lines produces relatively sharp edges.
When lid 14 is opened about the hinge, the opening force is sufficient to break the frangible connections 252 along frangible line 256 and panel 250 remains adhered to panel 64 of lid 14. It will be recognized that additional force is required to open packet 10 initially when the frangible connections 252 are to be broken, as compared with the force required to reopen a packet 10, in which the frangible connections have been previously broken.
The additional force required to break the frangible connections will be apparent to the customer or user.
Thus it will be evident to the customer or user if packet 10 has been previously opened.

Removal of panel 250 from collar 16, by breaking frangible connections 252 along frangible link 256 leaves an access slot 86 in front wall 80 as particularly shown in Figure 1. Access slot 86 has a clean, smooth edge 258 free of fraying.
~ith further reference to Figure 1, collar 16 has an upper edge 94 which includes opposed hori-zontal side edges 96 at a rearmost portion of side walls 82 and 84; inclined side edges 98 inclined down-wardly from horizontal side edges 96 towards front wall 80, and inclined front edges 100 in front wall 80.
With reference to Figure 3, there is shown a blank 110 for forming the packet 10. The numbers employed to identify the parts of packet 10 in Figures 1 and 2 have been increased by 100 in identi-fying the corresponding parts of blank 100.

The side walls 40 and 42 of packet 10 are formed by front side wall flaps 140a and 142a and rear side wall flaps 140b and 142b.
-- 1.5 A crease and fold line 118 connects rear wall panel 136 to lid-forming portion 114, and defines the hinge line 18 of the packet 10.
A crease and fold line 124 connects front wall panel 134 to collar-forming portion 116 and defines the front folded edge 24 of the packet 10.

Side wall flaps 140a and 140b have inclined edges 120a and 120b, respectively, which form side edge 20 of packet 10.
Side wall flaps 142a and 142b have inclined edges 122a and 122b, respectively, which form side edge 22 of packet 10.
. Lid-forming portion 114 includes a front wall panel 150, a rear wall panel 152, a top wall panel 154, outer side wall flaps 156 and 158, and the reinforcing panel 64.
A crease and fold line 160 is formed between front wall panel-150 an~ outer side wall flap 156;
and a crease and fold line 162 is formed between front wall panel 150 and outer side wall flap 158.
A cr~ase and fold line 130 is formed between reinforcing panel 64 and front wall panel 150. Crease and fold line 130 forms the folded edge 30 of packet 10 .
A crease and fold line 157 is formed between front wall panel 150 and top wall panel 154; and a crease and fold line 159 is formed between top wall panel 154 and rear wall panel 152.
Crease and fold lines 161 are formed between top and side flaps 66 and 70, respectively, and top and side flaps 68 and 72, respectively.
Crease and fold lines 163 are formed between side flaps 70 and 72 and rear wall 52.
Arrowhead or V-shaped slots 165 are defined between lid-forming portion 114 and body-forming portion 112.
- 17 ~
Each arrowhead slot 165 includes a curved head 167 spaced outwardly of the adjacent crease and fold line 129, with a short cut 169 extending from curved head 167 to the crease and fold line 118 which forms hinge line 18.
Side flaps 70 and 72 each have an exposed edge 171 defining one side of slot 165.
Each exposed edge 171 includes an inclined edge 173 which diverges outwardly relative to the opposed inclined edge 120b, 122b, respectively.
Inclined edge 173 terminates in a sub-stantially horizontal edge 175.
Collar-forming portion 116 includes a front wall panel 180, a spacer panel 181 and side wall panels 182 and 184.
Removable panel 350 is connected to collar-forming portion 116 by frangible connections 352 which are separated by elongated slits 354 along a frangible line 356.
Inclined upper edges 187 of collar-forming portion 116 define the inclined side and front edges 98 and 100 of collar 116.
Perforated fold lines 188 and 190 between front wall panel 180 and side wall panels 182 and 184, respectively, define the lines 88 and 90 of collar 16.
A perforated fold line 191 is formed between panels 180 and 181.
Side wall panels 182 and 184 have inclined lower edges 193 and 195.
Large slots 197 and 199 are defined between inclined lower edges 193 and 195 and 120a and 122a respectively.
The folding along perforated fold line 191 and crease and fold line 124 produces a so-called Z-fold formed by front wall 34, spacer panel 181 and front wall 80 of collar 16, fold 24 and the fold at line 191.
With further reference to Figure 5, a sealed packet 10 has a transparent foil wrapping -200 and a tear strip 202 having a tear tab 204.
Tear strip 202 conseals line 33 on the front face of carton 10. As currently used in Canada the tear strip 202 bears the legend CIGARETTES.CANADA.-CIGARETTES.DUTY PAID.DROIT ACQUIT., which legend is repeated along the strip. Location of the tear strip 202 along line 33 leaves the remaining large surface areas of the packet 10, bearing decorative and information material, unobstructed.
In the assembly of the carton 10, the blank 110 is delivered in a horizontal path. Reinforcing panel 64 is folded about crease and fold line 130 and is adhered to the inside face of front wall panel 150, and collar-forming portion 116 is folded about perforated fold line 191 and crease and fold line 124.
In this latter operation access is required from the side and the large slots 197 and 199 facilitates handling and folding by existing equip-ment employed in assembly of conventional two-blank designs.
Spacer panel 181 is glued to the interior face of front wall panel 134 of body forming portion 112.
In subsequent operations rear side wall flaps 140b and 142b are folded about crease and fold lines 120 and base flaps 125 are folded about crease and fold lines 131.
Base wall panel 138 is folded about crease and fold lines 133a and 133b, respectively.
Front wall flaps 140a and 142a are folded about crease and fold lines 127 and the inside faces of flaps 140a and 142a are glued to the outside faces of flaps 140b and 142b. In this way the front side wall flaps form the outer surfaces of side walls 40 and 42 and smooth corners are formed at fold lines 44 and 46 on the front face of the packet 10.
With the folding of front side wall flaps 140a and 142a about crease and fold lines 127, side walls 82 and 84 of collar 16 are formed by folding side wall panels 182 and 184 about perforated fold lines 188 and 190. The side walls 82 and 84 are disposed inwardly of flaps 140b and 142b.
In this way the body 12 with the collar 16 and panel 250 spaced inwardly thereof is formed.
In the assembly of lid 14 top flaps 66 and 68 are folded about crease and fold lines 161 and side flaps 70 and 72 are folded about crease and fold lines 163, and top wall panel 154 is folded ~bout crease and fold line 159. In this way top flaps 66 and 68 are disposed on top wall panel 154 to form top wall 54.
Front wall panel 150 is folded about crease and fold line 157 and outer side wall flaps 156 and 158 are folded about crease and fold lines 160 and 162 respectively and the outer faces of side flaps 70 and 72 are glued to the inner faces of side flaps 156 and 158 to form side walls 56 and 58.
- 21 ~
The provision of arrowhead slots 165, results in the exposed edge 171 of side flaps 70 and 72 being spaced inwardly of the side edges 26 and 28 defined by outer flaps 156 and 158. This spacing provides some tolerance in the location of flaps 70 and 72 against flaps 156 and 158 for adhesion. Thus even if top flaps 66 and 68 are slightly spaced from top wall panel 154 when flaps 70 and 72 are adhered to flaps 156 and 158, respectively, the exposed edge 171 of side flaps 70 and 72 is still spaced inwardly of the side edges 26 and 28 so that lid 14 can still be closed to form a cuboid packet 10 with smooth surfaces free of gaps at the juncture of lid 14 and body 12.
The ears 32 formed in the front sides of collar 16 frictionally engage the inside of side walls 56 and 58 thereby assisting in maintaining the packet 10 in the closed configuration.
An assembly of cigarettes, typically wrapped in a metallized paper foil is inserted in the assembled packet.
Adhesive spots 260 are applied to the front face of panel 250, or adhesive spots 262 may be applied to the inwardly directed face of reinforcing panel 64. It is also possible to apply adhesive spots 256 to panel 20 and adhesive spots 258 to panel 64. Lid 14 is closed so that panel 64 and panel 250 are adhered together by adhesive spots 260 and/or 262.
In the closed configuration the horizontal side edges 96 of collar 16 engage the top flaps 66 and 68. The inclination of side edges 98 and front edges 100, on the other hand, facilitates closure of the packet 10 by the effective removal of the .front upper corners of collar 16 which would other-wise engage reinforcing panel 64 during closure such that closure of packet 10 would either crush or deform the upper f`ront corners of collar 16, or the front wall 50 of lid 14 would be deformed so that a smooth front face would not be obtained on packet 10 .
By reference to Figure 3 it will be observed that collar-forming portion 116 has two major panels namely front wall panel 180 and spacer panel 181. In particular spacer panel 181 has a height at least two-thirds the height of front wall panel 180.
~ ,'r~7~3 In addition side wall panels 182 and 184 which are connected to front wall panel 180 along perforated fold lines 188 and 190 respectively, are not connected at all to spacer panel 181 and are spaced from perforated fold line l91o Suitably the spacing of the inclined lower edges 193 and 195 of side wall panels 182 and 184 respectively, from per-forated fold line 191 is at least one-quarter the height of spacer panel 181 so as to ensure that relatively large slots 197 and 199 are formed to facilitate side entry of conventional package assembly equipment employed with two-blank designs, in assembly.
The provision of panels 180 and 181 both of major surface area with the side panels 182 and 184 connected to panel 180 and spaced a significant distance from fold 1-91 represents a significant difference over the single blank designs described in the prior patents referred to above.
The lower edge 193 and 195 can also be made perpendicular to fold lines 188 and 190, however, this diminishes the si~e of slots 197 and 199, and in particular the mouth of slo~ 197 formed at the outer opposed corners of panel 182 and flap 140a, and the mouth of slot 19 formed at the outer opposed corners of panel 182 and flap 142a, is then much narrower and this hinders side access of the package assembly equipment.
By forming edges 193 and 195 parallel to the opposite edges 120 and 122a, respectively, of side wall flaps 140a and 142a, the large slots 197 and 199 are formed with a wide mouth for access of the equipment.
In blank 11~, the width of rear wall panel 136 of body-forming portion 112 is slightly narrower than the width of front wall panel 134. More especially in forming a substantially cuboid package 10,-the width of rear wall panel 136 plus four times the thickness of the blank 110 (i.e., the thickness of side walls 40 and 42 formed from flaps 140a and 140b and 142a and 142b respectively) equals the width of front wall panel 134.
` The outer side edges of lid forming-portion 114 and body-formirlg portion 11~ of blank 110 are substantially in line or form a straight line; and the outer side edges of collar-forming portion 116 are spaced slightly inwardly or are offset inwardly with respect to such line. In other words the outer edge of side wall panel 182 of collar-forming portion 116 is spaced slightly inwardly of a straight line formed by the outer edge of front side wall - 25 ~
flap 140a, base flap 125, rear side wall flap 140b, side flap 70, top flap 66 and outer side wall flap 156.
The outer edge of side wall panel 184 has a similar relationshiP with the flaps of body-forming portion llZ and lid-forming portion 114 on the opposed side of` blank 110.
Thus a substantially cuboid packet of the hinged lid type, with smooth front and side walls, is provided from a single blank using equipment already employed by cigarette packing companies for separate blank designs.
As can be seen in Figure 5 a transparent foil wrapping 200 can be formed around such a package in a conventional way, and a tear strip 202 indicating that Excise Duty has been pre-paid can be applied along the smooth juncture of the lid and body at the front f`ace of the package 10.
On the other hand, the transparent foil wrapping 200 is not employed in all embodiments.
The use of crease and fold lines in the invention produces relatively curved, smooth corners, whereas the use of perforated fold lines produces relatively sharp edges.
When lid 14 is opened about the hinge, the opening force is sufficient to break the frangible connections 252 along frangible line 256 and panel 250 remains adhered to panel 64 of lid 14. It will be recognized that additional force is required to open packet 10 initially when the frangible connections 252 are to be broken, as compared with the force required to reopen a packet 10, in which the frangible connections have been previously broken.
The additional force required to break the frangible connections will be apparent to the customer or user.
Thus it will be evident to the customer or user if packet 10 has been previously opened.
