Definitions

  • the present invention relates to a novel container with an inner liner for wrapping consumer articles.
  • the inner liner and the container of the present invention find particular application for elongate consumer articles.
  • containers formed from folded laminar blanks.
  • elongate consumer articles such as cigarettes and cigars are commonly sold in rigid box shaped containers.
  • These containers can be hinged lid containers having a box portion with a lid connected to the box about a hinge line extending across the rear wall of the container. In use, the lid is pivoted about the hinge line to open the pack and provide access to the smoking articles held in the box.
  • the container further includes an inner frame partly wrapped around the consumer articles. This may provide further rigidity to the container as well as protect the consumer articles. In cases where the inner frame extends above an upper edge of the box portion, the inner frame typically also provides a surface against which the lid can close.
  • the invention provides a container comprising consumer articles, an inner liner for wrapping consumer articles, which inner liner is partially or completely wrapped around the consumer articles, and a box portion housing the consumer articles wrapped by the inner liner, wherein the inner liner has a rectangular shape with two short sides and two long sides, the inner liner has an end area adjacent to each short side of the inner liner, the two end areas adjacent to the two short sides do not have slits, the inner liner has one or more intermediate areas between the two end areas, and the one or more intermediate areas have a plurality of slits.
  • the consumer articles can be elongate smoking articles, preferably cigarettes, cigarillos and cigars, more preferably cigarettes
  • the slit-containing inner liner is stretchable, that is, it can be stretched. Stretching of the inner liner has the effect that edges of the slits move apart from each other so that the slits become holes. Depending on the degree of stretching the shape of the holes can vary from a flat ellipse over a more oval shape to a circle. These holes can have areas of about of about 0.05 square millimeters to about 1 square centimeter, preferably to about 0.1 square millimeters to about 0.75 square centimeters, and more preferably of about 0.3 square millimeters to about 0.5 square centimeters. Because of the formation of the holes the surface area of the inner liner is increased.
  • this increase of a surface area is about 10 percent to about 50 percent, preferably about 15 percent to about 40 percent, and more preferably about 20 percent to about 30 percent, compared to the surface area of the inner liner before stretching.
  • all slits in the inner liner of the invention do have the same length and are arranged in a regular pattern, more preferably with an essentially constant distance between the single slits. This will lead, with or without the essentially constant distance between the single slits, after stretching to a regular mesh pattern, and the resulting holes will form a meshed area.
  • Stretching the inner liner has, in addition to the increase of the surface area by the formation of holes, two additional effects. Because of the presence of holes in the inner liner after stretching the inner liner will more and more lose its sheet-like structure and will more and more adapt a wave-like structure in the slit-containing and hole-containing areas of the inner liner. This wave-like structure of parts of the inner liner will lead to a more bulky structure of the inner liner and will as a consequence lead not only to an increase of the surface area but also to a volume increase of the inner liner.
  • the second additional effect is that stretching will move the edges of the slits out of the plane of the inner liner so that these edges will be protruding out of the inner liner plane. This again leads to a slight volume increase.
  • these protruding edges of the holes after stretching can get in touch with the consumer articles and can help to keep these consumer articles in place as a result of a friction between the protruding edges and the consumer articles.
  • slits in the inner liner have different orientations stretching will only have a limited effect on the above-described increase of the inner liner's surface area and volume. For example, if a first slit is parallel to the longitudinal axis of the inner liner and a second slit perpendicular thereto, then applying a stretching force parallel to the longitudinal axis of the inner liner will only have an influence on the slit which is arranged perpendicular to the longitudinal axis and only this slit will be transformed into a hole. For that reason it is preferred that all slits within one inner liner of the subject invention have the same orientation, for example, that all slits are parallel or perpendicular to the longitudinal axis of the inner liner.
  • Stretching of an inner liner of the subject invention with slits perpendicular to the longitudinal axis of the inner liner by applying a force parallel to this longitudinal axis will lead to an elongation of the length of the inner liner and at the same time a slight contraction of the width of the inner liner. Stretching of an inner liner of the subject invention with slits parallel to the longitudinal axis of the inner liner by applying a force perpendicular to this longitudinal axis will lead to an elongation of the width of the inner liner and at the same time a slight contraction of the length of the inner liner.
  • an elongation of the length is more preferred. Consequently, an inner liner is more preferred in which all slits are perpendicular to the longitudinal axis of the inner liner. It is however also preferred to have slits parallel and perpendicular to the longitudinal axis of the inner liner. This allows at the same time an increase of the inner liner's length and width.
  • Stretching of the inner liner of the subject invention can be done by the manufacturer or by the consumer or by both. If stretching is done by the manufacturer during production of the container of the invention, this has the advantage that as a result of the increase of surface area after stretching less material is used for the inner liner. Thus material saving is an advantage which is achieved if stretching is done on the manufacturer's side. As discussed above, stretching of the inner liner also leads to a volume increase. Thus, if stretching is done on the manufacturer's side, this can be used to cover some extra space which is not needed for the consumer articles within a given container. For that purpose it is advantageous if the slits are arranged parallel to the longitudinal axis of the inner liner because then the above-described increase of the inner liner's width can be obtained which will cover the empty space within the container.
  • the inner liner is not stretched on the manufacturer side this then can be done by the consumer. Since the inner liner has not been stretched by the manufacturer, the consumer can use the full range of stretching available for a given inner liner and has for that reason more flexibility in adapting the volume of the inner liner.
  • the inner liner of the invention can be made of any sheet or sheet-like material.
  • the inner liner is made of a laminate, a cardboard, a metalized cardboard, a paper, a metalized paper or a foil.
  • the inner liner is a laminate made of an uncoated paper onto which an adhesive starch followed by an aluminum foil followed by a top lacquer or a slip coating are laminated.
  • the inner liner has a base weight of at least 20 grams per meters squared, preferably 30 to 100 grams per meters squared and more preferably 50 to 80 grams per meters squared.
  • a typical length of the short sides of an inner liner used in a cigarette pack is about 6 centimeters to about 9 centimeters, preferably about 7 centimeters to about 8 centimeters.
  • a typical length of the long sides of an inner liner used in a cigarette pack is about 23 centimeters to about 28 centimeters, preferably about 24 centimeters to about 25 centimeters.
  • the above-described lengths are those typically provided by the manufacturer, that is, the lengths of the inner liner either without stretching by the manufacturer or after stretching by the manufacturer. Additional stretching by the consumer might lead to an increase of these lengths as it was described in detail above.
  • the plurality of slits can be 50 or more slits, preferably 75 or more slits and more preferably 100 or more slits. These slits are not present in the end areas but only in the intermediate areas between the two end areas of the inner liner.
  • the inner liner can contain one or more additional areas without slits. For example, if the inner liner of the invention is to be used for a cigarette pack an additional area which does not contain any slits will be located in the middle of the two long sides of the inner liner.
  • the end areas without slits will each have a length of about 4 centimeters to about 6 centimeters
  • the intermediate areas with slits will similarly each have a length of about 4 centimeters to about 6 centimeters
  • the additional area without slits will have a length of about 4 centimeters to about 6 centimeters.
  • the end areas without slits can have the same or different sizes.
  • the intermediate areas with slits can have the same or different sizes.
  • the additional area without slits can have the same or different size than the end areas without slits and the intermediate areas with slits.
  • front, “rear”, “top”, “bottom”, “side”, “upper,” “lower” and other terms used to describe relative positions of the components of the inner liner and the container according to the invention refer to the container in an upright position with the collation of consumer goods housed in the container and with an open end of the box portion at the top and the consumer goods accessible from the upper end at the front.
  • side and similar terms are used with reference to side walls of the inner liner and the container when the container is viewed form the front in its upright position.
  • the material of the inner liner is completely penetrated. Typically this is achieved by cutting completely through the inner liner material.
  • These slits or cuts have a length of about 1 millimeters to about 2 centimeters, preferably of about 2 millimeters to about 1.5 centimeters, and more preferably of about 4 millimeters to about 1 centimeter.
  • These slits are preferably arranged in the inner liner such that all slits have the same length and are distributed over the intermediate areas in a regular way so that a regular pattern results, in particular once the inner liner is stretched. It is further preferred that all these slits of same length are arranged parallel to each other such that all have the same orientation, and more preferably all these slits of same length are perpendicular to the longitudinal axis of the inner liner.
  • the inner liner of the invention can be prepared by different ways.
  • the inner liner material as described above can be cut into the desired shape. Thereafter cuts using any kind of knife can be entered at the desired positions.
  • a circular rod with one or more, more preferably a plurality of knifes, at its surface is used.
  • Such devices are known as "Skin Graft Mesher".
  • the inner liner material is brought into contact with this device such that cuts are entered into the inner liner at the desired positions.
  • cutting of inner liners can be done either in a separate step or as part of the usual embossing process during preparation of the cigarette packs.

  • the container according to the subject invention comprising consumer articles wrapped by an inner liner according to the invention and a box portion housing the wrapped consumer article is preferably a container for elongated smoking articles, such as cigarettes, cigarillos and cigars. More preferably this container is a cigarette pack.
  • a cigarette pack can either be a hinged-lid pack or a soft pack (that is, a container with a box portion made from a laminar blank of a thinner, more easily deformable material, such as paper, than typically used for hinged-lid packs) or a pack having a sliding mechanism for opening the container.
  • containers according to the invention may be designed for different numbers of cigarettes of conventional size, king size, super-king size, slim or super-slim cigarettes, with diameters for the cigarettes ranging from 4 millimeters to 9 millimeters.
  • containers in accordance with the present invention can also be used with a variety of consumer goods other than smoking articles.
  • the dimensions of container and collation with wrapped consumer articles are adapted to each other such that the collation preferably accurately fits into the container.
  • the outer surfaces of the inner liner touch the inner surfaces of the container and the collation is kept in place and is not able to move within the container.

  • Fig. 2 shows the inner liner of Fig. 1 after stretching same so that the slits are expanded and form flat ellipses.
  • Fig. 1 shows an inner liner 10. Adjacent to the short sides of the inner liner 10 there are at the upper and lower ends of the inner liner 10 two end areas 12 which do not have any slits 14. In the areas in the neighbourhood of these end areas 12, namely in the intermediate areas 16, a variety of slits 14 can be seen. In between the two intermediate areas 16 an additional area 8 is shown which, just as the end areas 12, does not contain any slits.
  • Fig. 2 shows the inner liner 10 of Fig. 1 after stretching. It can be seen that the slits 14 are slightly widened and are transformed into holes 20. The degree of stretching is low in Fig. 2 so that the holes 20 of inner liner 10 in Fig. 2 only form flat ellipses associated with a slight increase of the length of the inner liner 10 and a slight decrease of the width of the inner liner 10. It is evident that, if a higher stretching force will be applied, some residual elongation of the length and some additional shortening of the width and at the same time the formation of circular holes will occur for the inner liner 10 of Fig. 2.
