Covered boxes or cartons are as a rule produced in this wise, namely that there is fitted into a base or body portion of pasteboard or the like a previously prepared neck-forming portion which is secured to the base portion by adhesive; the lid, which is made independently, being then mounted on the base portion and an edge strip being applied to the vertical walls of the box so that after severance of the strip at three sides there is left a hinged joint connection of the lid with the base portion.
In order to simplify and cheapen production, it has already been proposed to produce covered boxes without the insertion of a separate neck forming element, flaps or wings of the blank from which the base portion of the box is formed being joggled. In this way there is obtained a simple article,- which, however. cannot so well withstand external stresses but which incorporates the principal properties of a covered box.
Ordinarily such boxes or cartons are adapted to receive two layers of cigarettes. If, as heretofore usual, the joggle is formed about midway of the height of the side walls of the box, the lower layer of cigarettes will be confined within the area beneath the neck portion while the upper .layer of cigarettes will be within an area confined by the neck portion. The ends of this upper layer bear against the inner walls of the neck portion, while, depending on the degree of joggling, there will be at both ends of the cigarettes of the lower layer an unoccupied space, so that the lower layer of cigarettes is not held tightly.
As is understood, cigarettes that are not well packed become unsightly, because their ends are damaged in consequence of vibration and tobacco trickles out at the ends.
As distinguished from this known method, according .to the present invention the side walls are so formed or are so associated with filling means that the cigarettes are secured against lengthwise displacement.
The invention contemplates widely difierent possible constructions.
For example, the arrangement may be such that the part of the vertical walls of the box beneath the neck is lower than the thickness of a cigarette, or the arrangement may be such that in stamping out the corners of the blank tongues are left which on forming the box bear against inner faces of the side walls beneath the neck portion and thus partly fill up the space beneath the joggle. Again, the side walls may be formed beneath the neck with inwardly extending ridges or otherwise embossed to compensate for the constriction due to joggling.
Such a box may be made from a single blank in which event one of the side walls of the base portion is unjoggled and adjoined to the lid portion, the hinge being either at the middle of the said wall or at the upper edge thereof.
If the hinge is disposed at the middle of the said wall. then on opening the box there is left a gap through which cigarettes of the upper layer m ght roll. To prevent this, in stamping out the blank there are left projecting tongues which occupy such a position in the formed box that they serve as guards preventing the cigarettes from rolling out.
For further explanation of the invention reference will be made to the figures of the accompanying drawings.
Fig. 1 shows in plan view the box blank used to produce the first named embodiment of my invention.
Fig. 2 shows in perspective the blank of Fig. 1 folded to form the box with the lid partly raised.
Fig. 3a shows in section the completely folded box without the sealing strip around but with the cigarettes contained therein and illustrating in detail how longitudinal displacement of the low.- er group of cigarettes is prevented.
Fig. 3b and Fig. 3c are sectional and perspective 5 views respectively of a modified construction.
Fig. 3 shows in perspective the completely folded box about which a sealing strip has been placed.
Fig. 4 shows in plan view the box blank used .to produce the first named modification of the invention.
Fig. 5 shows in perspective theblank of Fig. 4 folded to form the box with the lid partly raised.
Fig. 6 shows in section the completely folded box made from the blank of Fig. 5 without the sealing strip around it, but with the cigarettes contained therein to illustrate in detail how longitudinal displacement of the lower group of cigarettes is prevented.
Fig. 7 shows in plan view the box blank used to produce the second named modification of the invention.
Fig. 8 is a sectional detail along line 8-8 of Fig. 7.
Fig. 9 shows in perspective the blank of Fig. 7 folded to form the box with the lid partly open.
Fig. 10 shows in plan view the box blank used to produce the third named modificationof the invention, and I Fig. 11 shows in perspective the blank of Fig.
10 folded to form' the box with the lid partly 'open.
In the example, according to Figs. 1-3 the box is formed from a single blank. The panel 1 forming the bottom of the box has the usual marginal wings or flaps 2, 3 and 4, while the panel 5 forming the lid has the usual marginal wings 6, 'l and 8 The two panels are connected by an intermediate portion 9 in the middle of which a score 10 is formed to afford a hinge.
The flaps 2 to 4 are joggled at 11, the joggles being so located adjacent .to the bottom panel 1 that thedistance of the joggle from the bottom of the box is less than the thickness of a cigarette. I
This results in the form shown in Fig. 3a in which the lower layer of cigarettes Z extends above the joggle 11, fitting the interior wall 8 of the rim of the lid and being thus restrained from displacement; in other words the spaces a: at the ends of the cigarettes Z are rendered innocuous.
There may be laid around the box an edge strip 12 as shown in Fig. 3. With covered boxes according to the invention the strip 12 may be applied before or after the filling of the box.
In the construction according to Figs. 4, 5 and 6 the box is also produced from a single blank.
The parts 1--11 are also present in this construct101'lpbl1t the joggles 11 are located centrally of the wings 2, 3, 4 so that the lower layer of cigarettes Z would be free to shift longitudinally but for the fact that there are left projecting from the wing 2 and the intermediate portion 9 tongues 13. When the box is folded, as shown in Fig. 5, the tongues 13 can be laid against the inner faces of the side walls beneath the joggles 11 so that they fill the unoccupied spaces kc.
. It will be seen that the lower layer of cigarettes Z is secured against lengthwise shift by the tongues 13 occupying the spaces 1:.
In the construction according to Figs. '7 to 9 the body of the box is again produced from a single blank, the parts 1 to 11 being provided as before.
In order with this construction to prevent endwise shift of the cigarettes of the lower layer 3, ridges 14 are embossed in the side walls 2 to 4 of the base portion beneath the joggles 11. These ridges project inwardly a distance equal to the amount of joggle and engage the cigarettes Z which are thus firmly held.
It is to be observed that in this construction the cigarettes are packed with their longitudinal axes parallel to the hinge.
Referring to Figs."1 to 9, attention is called to the flap portions 15 which project at corners of the wings 3, 4. In forming the box (see Fig. 9) these flaps are folded so that in the open position of the box they form stops which prevent the cigarettes of the upper layer from rolling-out towards the lid. The lower portions of the fiaps 15 which come in contact with the hinge-forming wall of the base portion 1 are preferably connected to said wall by adhesive or the like so that the upper parts of said flaps constitute fixed stops.
Whereas in the previously described constructions the hinge joint for the lid was located centrally of the portion 9, in the construction according to Figs. 10 and 11 the hinge joint is shifted to the upper edge of the base portion and in this case no safety device is required to prevent cigarettes of the upper layer from rolling out, as the rear wall of the box is a full wall.
In all the constructions illustrated the corners 16 of the wings 2, 3, 4 are rounded so that in the formed box sharp corner connections which might interfere with proper closing of the :.d are obviated. The rounded corners facilitate close mating of the lid rim with the neck.
The new form of box can be produced in a combined box making and packing machine which permits the filling of the box with cigarettes before closing and even before forming the box. Consequently it can be so arranged that first the box is filled with cigarettes and then the edge strip is gummed thereon, thread 17 (Figs. 3a, 3b) being .laid in the gap between the rim of the lid 5 and the shoulder of the neck before the edge strip is applied. This said thread is gummed over with its ends projecting and in known manner facilitates the. tearing of the packing, the thread also acting to close air-tightly the gap between the edge of the rim and the base portion 1 of the box.
1. A carton to receive two superimposed layers of cigarettes, comprising a base portion including a bottom panel, walls upstanding from said panel and formed with a neck, a lid having a rim engageable with said neck and, inwardly projecting means integral with said walls for reducing the effective clearance between opposite walls for the lower layer of said cigarettes to substantial equality with the clearance between said opposite walls for the upper layer of said cigarettes.
2. A cigarette carton comprising a base portion including a bottom panel, walls upstanding from said panel and joggled to form a neck, and a lid having a rim engageable with said neck, opposed side walls beneath said neck being ridged to reduce the clearance therebetween to substantially the same amount as between corresponding opposed sides of said neck for reception of a layer of cigarettes disposed lengthwise between said opposed side walls.
3. A cigarette carton formed from a single blank and comprising a base portion including a bottom panel, walls upstanding from said panel, three of said walls being joggled to form a neck,
a lid having a rim engageable with said neck, and
an upstanding wall connecting said lid and said panel, the joggles of said walls being located at a distance from the bottom of the box which is less than the thickness of a cigarette.
4. A cigarette carton comprising a base portion including a bottom panel and wings foldable to present walls upstanding from said panel and joggled to form a neck, said wings being rounded at the corners, and a lid having a rim engageable with said neck, and tongues formed on said wings and adapted to be folded over the inner faces of opposite walls beneath the joggles and to reducethe effective clearance for a layer of cigarettes extending between said walls.
5. A carton having a neck formed by joggling the side walls of said carton, and ridges formed in said side walls below said neck whereby the eifective clearance between opposed walls below Said neck is made substantially equal to the clearance between corresponding opposed sides of said neck.
6. A cigarette carton comprising a base portion including a bottom panel, four walls upstanding from said panel, three of said walls being joggled to form a neck, a lid having a rim engageable with said neck, the fourth wall havingia hinge connection with said lid at the upper edge of said wall, and ridges in the joggled walls arranged below said neck and projecting inwardly a distance equal to the amount of joggle, so that the cigarettes of both layers will be firmly held.
