This application also claims priority under 35 USC §119 to European Application No. 04257628.0, filed Dec. 8, 2004.
The present invention relates to a novel hinge-lid container and in particular to a novel hinge-lid pack or carton for elongate smoking articles such as cigarettes.
Cigarettes are commonly sold in hinge-lid cardboard packs having a box portion and a lid portion, which is hinged to the rear wall of the box portion. In use, with the pack in an upright position, the front of the lid portion is pivoted up and to the rear by the consumer to open the pack and thereby allow access to a bundle of cigarettes standing in the box portion. When the lid portion is closed, the front, side and rear walls of the lid portion form vertical extensions of the corresponding walls of the box portion.
Hinge-lid cigarette packs normally also include an inner frame or collar mounted inside the front and sides of the box portion, at least a portion of which projects from the box portion into the space covered by the lid portion in the closed position. A central cut-out is provided in the front wall of the inner frame to allow the consumer to readily remove cigarettes from the hinge-lid pack in the open position. In use, the inner frame provides interference or frictional engagement with the lid portion as it opens and closes, thereby helping to prevent accidental opening of the pack and helping to retain the lid portion in the closed position when desired. In addition, the inner frame also serves to reinforce the box portion of the hinge-lid pack.
Typically, the box portion and the lid portion of the hinge-lid cigarette pack are formed from a single, folded, laminar cardboard blank and the inner frame is formed from a second, separate, laminar cardboard blank. To produce the pack, a bundle of cigarettes wrapped in, for example, metallised paper or aluminium foil is placed together with the second laminar cardboard blank in a pocket on a wrapping wheel, which is lined with the first laminar cardboard blank. The wrapping wheel is indexable between a number of stations and as the pocket indexes around from station to station, the first laminar cardboard blank is folded in stages around the wrapped bundle of cigarettes and inner frame to form the hinge-lid pack. Typically, the formed hinge-lid cigarette pack is then shrink wrapped or otherwise over wrapped with a transparent polymeric film of, for example, polyethylene or polypropylene.
Hinge-lid containers with an integral inner frame, which are formed from a single, folded, laminar cardboard blank are also known. The blanks for such containers can be complicated and, in order to erect the container, require reverse folding that is difficult to achieve using conventional machinery.
Laminar cardboard blanks from which hinge-lid cigarette packs and other hinge-lid containers are formed often include an inner lid panel that extends from the panel of the blank which, in use, forms the front wall of the lid portion of the pack. During production, this inner lid panel is folded through 180 degrees and affixed to the inner surface of the lid front wall panel of the blank so that in the formed hinge-lid container it rests against the inside of the front wall of the lid portion thereof. As well as providing reinforcement to the lid portion of the formed hinge-lid container, the inner lid panel may be provided with retention means that, in use, cooperate with portions of an inner frame mounted in the container to retain the lid portion thereof in a completely closed position, with the lower edges of the lid portion abutting the upper edges of the box portion. In addition, the outer surface of the inner lid panel may be advantageously printed with consumer information. The fold line formed between the inner lid panel and the lid front wall panel also advantageously provides a neat, dull lower front edge to the lid portion of the formed hinge-lid container.
In spite of the benefits discussed in the preceding paragraph, the inclusion of an inner lid flap in hinge-lid cigarette packs and other hinge-lid containers disadvantageously results in the lower region of the front wall of the lid portion of the container being of increased thickness compared to the upper region of the front wall of the box portion thereof. Due to the presence of the reinforcing flap, the bottom edge of the front wall of the lid portion is twice the thickness of the top edge of the front wall of the box portion against which it abuts when in the closed position. Such a thickness differential across the lid line is undesirable as the misalignment between the front wall of the lid portion and the front wall of the box portion can give rise to creases or wrinkles in polymeric film over wrappers subsequently applied to the formed hinge-lid container; as well as being unsightly, creases or wrinkles formed in the polymeric film may interfere with subsequent manufacturing and transport operations involving the over wrapped hinge-lid container.
According to the present invention there is provided a hinge-lid container comprising: a box portion; a lid portion hinged to the box portion across a rear wall thereof for pivotal movement between an open position and a closed position; a flap extending across a lower part of the inner surface of a front wall of the lid portion; and a spacer panel extending across at least an upper part of the inner surface of a front wall of the box portion, the spacer panel having a free edge that extends across the inner surface of the front wall of the box portion, wherein the spacer panel does not project from the box portion into space covered by the lid portion in the closed position.
The inclusion of a spacer panel adjacent the inner surface of the front wall of the box portion spaces the upper part of the front wall of the box portion from the contents thereof. As it does not project into the space covered by the lid portion in the closed position, the spacer panel thereby compensates for the increased thickness of the lower part of the inner surface of the front wall of the lid portion due to the flap. By reducing or eliminating any thickness differential across the lid line of hinge-lid containers according to the invention, the spacer panel advantageously avoids misalignment between the front wall of the lid portion and the front wall of the box portion thereof that could result in creases or wrinkles in an over wrappers subsequently applied to the container.
The spacer panel also advantageously reinforces the box portion of hinge-lid containers according to the invention. Consequently, hinge-lid containers according to the invention having substantially the same rigidity as known hinge-lid containers may be advantageously formed from reduced thickness laminar cardboard blanks or other materials and/or without the need for inclusion of an inner frame.
Preferably, the spacer panel is of substantially the same thickness as the flap.
Preferably, the spacer panel has a free edge that extends across the inner surface of the front wall of the box portion substantially parallel to the upper edge of the front wall of the box portion.
The flap preferably depends from and is folded about the upper edge of the front wall of the lid portion. The flap may be affixed to the inner surface of the front wall of the lid portion using, for example, an adhesive. The spacer panel may be affixed to the inner surface of the front wall of the box portion using, for example, an adhesive.
In a preferred embodiment of the invention, the spacer panel is integral with the front wall of the box portion. More preferably, the spacer panel depends from and is folded about the upper edge of the front wall of the box portion.
Preferably, the box portion, lid portion, flap and spacer panel are formed from a one-piece folded laminar blank.
In other embodiments of the invention, the spacer panel may be a separate panel that is, for example, adhered with a suitable adhesive or otherwise affixed to the inner surface of the front wall of the box portion. In such embodiments, the spacer panel has a pair of opposed free edges that extend across the inner surface of the front wall of the box portion.
Hinge-lid containers according to the invention may further comprise a separate, non-integral inner frame mounted in the box portion and projecting from the box portion into space covered by the lid portion in the closed position. In such embodiments, the spacer panel is positioned between the inner surface of the front wall of the box portion and the inner frame. Where hinge-lid containers according to the invention comprise an inner frame, the spacer panel may be integral with the inner frame as shown in
Where hinge-lid containers according to the invention comprise an inner frame, the spacer panel may alternatively be a separate panel that is adhered or otherwise affixed to the outer surface of the lower part of the inner frame, which is mounted in the box portion of the hinge-lid container. The spacer panel may be the same or a different size to the part of the lower part of the inner frame, which is mounted in the box portion. Furthermore, where the spacer panel is not integral with the inner frame, the spacer panel and the inner frame may be of different thickness and/or formed from different material.
The spacer panel may be of substantially the same dimensions as the front wall of the box portion. This is particularly preferred in embodiments where, as described below, the hinge-lid container according to the invention comprises a first opening extending through the front wall of the box portion and a second opening extending through the spacer panel. To reduce the quantity of cardboard or other material required to produce hinge-lid containers according to the invention, the spacer panel may, however, be of reduced dimensions compared to the front wall of the box portion. For example, the spacer panel may be of substantially the same dimensions as the flap. Preferably, the spacer panel extends across at least a central portion of the upper part of the inner surface of the front wall of the box portion. More preferably, the spacer panel extends across substantially the entire width of the inner surface of a front wall of the box portion.
To allow a consumer to view, for example, the contents of the hinge-lid container or logos or other indicia provided on the inner frame or the outer surface of an inner wrapper in which the contents of the hinge-lid container are wrapped, hinge-lid containers according to the invention may further comprise: a first opening extending through the front wall of the box portion; and a second opening extending through the spacer panel, at least a portion of the second opening being aligned with at least a portion of the first opening.
Where hinge-lid containers according to the invention include an inner frame, they may further comprise a third opening extending through the inner frame, at least a portion of the third opening being aligned with at least a portion of the first opening and with at least a portion of the second opening in order to allow a consumer to view the contents of the container or logos or other indicia provided on the outer surface of an inner wrapper in which the contents of the container are wrapped.
The first opening, second opening and third openings may be of the same or different size and shape. For example, through an appropriate choice of the relative dimensions of the first opening and the second opening, the second opening provided in the spacer panel of hinge-lid containers according to the invention may advantageously be used to provide relief or depth to the first opening provided in the front wall of the box portion thereof.
Hinge-lid containers according to the present invention may be particularly advantageously employed as packs for elongate smoking articles such as cigarettes and/or as cartons for holding a plurality of packs of elongate smoking articles such as cigarettes. For example, through an appropriate choice of the dimensions thereof, hinge-lid containers according to the invention for housing different numbers of conventional size, king size, super-king size, slim or super-slim cigarettes may be produced.
A hinge-lid container according to a preferred embodiment of the invention comprises: a box portion; a lid portion hinged to the box portion across a rear wall thereof for pivotal movement between an open position in which the lower edge of a front wall of the lid portion is spaced apart from the upper edge of a front wall of the box portion; a flap extending across a lower part of the inner surface of the front wall of the lid portion, the flap depending from and being folded about a hinge-line forming the lower edge of the front wall of the lid portion, and a spacer panel extending across the inner surface of the front wall of the box portion, the spacer panel depending from and being folded about a hinge-line forming the upper edge of the front wall of the box portion, wherein the spacer panel does not project from the box portion into space covered by the lid portion in the closed position.
