Definitions

  • the present invention relates to a container for consumer goods comprising an outer housing, an inner package within the outer housing and an adhesive label covering the access opening on the outer surface of the inner package through which the consumer goods can be removed.
  • a respective resealable adhesive label is known from EP 3 299 314 A1 disclosing a container for consumer goods comprising an outer housing, wherein the outer housing comprises a box and a lid hinged to the box.
  • An inner package of consumer goods has an access opening through which the consumer goods can be removed.
  • An adhesive label is provided to cover the access opening and extends beyond the periphery of the access opening of the inner package.
  • the adhesive label is at least partially releasably affixed to the inner package by a resealable adhesive provided on a first area of the inner surface of the adhesive label extending about at least the lower periphery of the access opening of the inner package.
  • a second area of the inner surface of the adhesive label is permanently affixed to the inner surface of the front wall of the lid of the outer container.
  • a further, third area of the inner surface of the adhesive label disposed between the first and second areas is substantially free of adhesive.
  • such an adhesive label has three different areas each comprising a different coverage or treatment: adhesive free, resealable adhesive and permanent adhesive.
  • adhesive free adhesive free
  • resealable adhesive resealable adhesive
  • permanent adhesive the manufacturing of such kind of adhesive label requires costly equipment and is complex and in particular, the initial resistance exerted by the adhesive label sealing the inner package while being opened is inconvenient for the user.
  • a container for consumer goods comprising an outer housing.
  • the outer housing comprises a box and a lid hinged to the box along a hinge line extending across a side wall of the container wherein the box and the lid have an inner and an outer surface.

  • the weakened line along the periphery of the access opening may also be prepared by a creasing or scoring line.
  • the adhesive label provided for sealing the access opening preferably has a peripheral shape corresponding to the peripheral shape of the access opening at least fully covering the access opening, but other shapes are also possible.
  • the shape may be rectangular, triangular, semi-circular, semi-oval or trapezoid, or may have any other suitable shape.
  • the shape and size of the label have to sufficiently extend beyond the periphery of the access opening to provide enough contact area for a circumferential sealing around the periphery of the access opening.
  • the adhesive label is preferably plane, i.e. flat and planar, wherein the adhesive label has an inner surface facing the outer surface of the inner package and an outer surface on the opposite side of the inner surface facing the inner surface of the lid. Moreover, the adhesive label is preferably flexible to be enabled to adapt its shape during the opening and closing of the container.
  • the adhesive label comprises a resealable adhesive in the first adhesive area, such that the adhesive label can be peeled off the outer surface of the inner package and reattached to the inner package for a number of times.
  • the adhesive label can be peeled off the outer surface of the inner package and reattached to it at least as many times as there are consumer goods, e.g. cigarettes, within the inner package. This allows for a repeated opening and closing the inner package without contaminating the consumer goods.
  • the resealable adhesive preferably provides sufficient adhesion for the label to be reattached.
  • Suitable resealable adhesives are known to a skilled person and a wide variety of adhesives are commercially available from a number of suppliers. The selection of suitable adhesives may depend on the material forming the inner package and the coating of the coated areas on the outer surface of the inner package to which the label is sealed or resealed during use.
  • the resealable adhesive may be a synthetic pressure sensitive hotmelt adhesive, a water based polyethylene adhesive, or a removable acrylic based adhesive.
  • the second adhesive area of the adhesive label comprising a permanent adhesive at least partially corresponds to the size and position of the access opening, preferably may be smaller than the size of the access opening, and more preferably may be 3 mm smaller than the size of the access opening.
  • the permanent adhesive of the second adhesive area may be a standard hotmelt adhesive.
  • the first coated area on the outer surface of the inner package reduces the adhesive force between the inner package and the adhesive label when the container is opened, i.e. the adhesive label is peeled off the inner package.
  • a container may be provided that can be easily opened.
  • the first coated area particularly facilitates the beginning of the opening movement of the container, i.e. the beginning of the lifting of the lid.
  • the coating of first coated area may be made from any suitable material such as siliconized varnish, release coating or wax.
  • the first coated area on the outer surface of the inner package may be applied by printing.
  • the printing can be carried out with one of the usual printing techniques, e.g. rotogravure printing, flexographic printing, offset printing, letterpress printing, silk screen printing or digital printing.
  • the third adhesive area of the adhesive label comprising also a permanent adhesive is affixed to the inner surface of the lid such that the adhesive label forms a S-shaped fold and uncovers the access opening when the lid is lifted, i.e. when the container is opened. Moreover, the permanent adhesive connection between the third adhesive area of the adhesive label and the inner surface of the lid ensures that the adhesive label fittingly returns to its sealing position when the lid is closed.
  • the first adhesive area and the first coated area overlie each other at least partially, when the adhesive label fully covers the access opening in the closed state of the container.
  • the first coated area is spaced apart from the access opening, i.e. there is a gap between the periphery of the access opening and the first coated area.
  • there can be arranged at least another coated area such that the reduction of the adhesive force of the first adhesive area of the adhesive label can be a stepwise reduction as regards the different coated areas.
  • the upwards direction is in direction of the lid and the downwards direction is in direction of the bottom of the box, there is an area of the inner package above and below the access opening. If the first coated area is located below the access opening, its adhesive reducing property has an impact on opening the container when the lid is lifted upwards.
  • the inner package further comprises a second coated area at least partially surrounding the periphery of the access opening on the outer surface of the inner package.
  • the second coated area may be located between the access opening and the first coated area, wherein the inner surface of the label comprises only a second adhesive area of permanent adhesive.
  • An adhesive label with only one type of adhesive over the whole inner surface reduces the complexity of label manufacturing, since the manufacturing of different areas with permanent, resealable and no adhesive is avoided.
  • the coating of the second coated area is less effective in reducing the adhesion of an adhesive than the coating of the first coated area which can be achieved by using different coatings or different thicknesses of the respective coating layers.
  • the first adhesive area still enables that the beginning of the lifting of the lid and consequently, the peeling of the adhesive label is eased, whereas the bonding or adhesive force between the second coated area and the adhesive label is higher than that between the first coated area and the adhesive label.
  • the resistance force against the peeling of the adhesive label is nominally higher, but by peeling the adhesive label the effective lever is elongated continuously. Accordingly, the force needed to peel off the adhesive label reduces continuously, provided that the peeling torque is kept constant.
  • the effectiveness of the coated areas on the outer surface of the inner package reduces stepwise from the first coated area towards the access opening.
  • the container has a first dimension in direction from the lid to the box, a second dimension perpendicular to the first dimension and parallel to the hinge line, and a third dimension perpendicular to the first and the second dimension.
  • the first dimension is the height
  • the second dimension is the width
  • the third dimension is the depth.
  • the width of the first coated area on the inner package is at least wider than the width of the access opening but smaller than the width of the adhesive label but smaller than the width of the adhesive label.
  • the width of the first coated area should be at least wider than the width of the access opening to generate a sufficient reduction effect on the adhesive force of the inner surface of the adhesive label.
  • the width of the first coated area does not exceed the width of the adhesive label, no coating will be wasted and the inner surface will not be contaminated with the coating of the first coated area.
  • the width of the first coated area on the inner package is at least wider than the width of the adhesive label.
  • the first coated area on the outer surface of the inner package is preferably larger than the first adhesive area on the inner surface of the adhesive label to allow for a reduced peeling force needed to peel off the adhesive label from the inner package. If the first coated area is larger than the first adhesive area of the adhesive label, the reducing effect on said peeling force affects the first adhesive area of the adhesive label to the full extent.
  • the height of the third adhesive area of the adhesive label is at least 3 mm, preferably at least 6 mm, and more preferably at least 9 mm.
  • the width of the first and the second coated area exceeds the width of the adhesive label on each side by at least 1 mm, preferably by at least 2 mm, and more preferably by at least 3 mm.
  • the coating of the first coated area and/or the second coated area comprises a silicone.
  • the width of the first coated area and the first adhesive area have a ratio of 1:2, preferably 1:1.5, and more preferably 1:1.
  • the pursued effect of reducing the adhesive resistance between the adhesive label and the inner package at the beginning of the opening movement of the container is maximised.
  • the double arrow 6a indicates the height direction
  • the double arrow 6b indicates the width direction
  • the double arrow 6c indicates the depth direction of the container 1, wherein lid 7 is on top or above of box 5 in the height direction.
  • hinge 9 is formed along the rear side of outer housing 3 in the width direction of container 1.
  • Inner package 11 may be formed from any suitable material including, but not limited to metal foil, metallised paper, metallised film or printed film.
  • Inner package 11 may be formed as a laminate of metallised or printed polypropylene film, metallised or printed polyethylene terephthalate film, laminates made of film and paper, such as metallised or printed polypropylene film, metallised or printed polyethylene terephthalate film with supercalandered paper or other laminates.
  • a resealable adhesive label 17 is attached to the outer surface of inner package 11 and the inner surface of lid 7. As container 1 shown in Fig. 1 is opened, i.e. lid 7 is lifted and rotated in direction of the rear side of container 1 around hinge 9, adhesive label 17 forms a S-shaped fold.
  • Adhesive label 17 comprises a first adhesive area 21 with a resealable adhesive and a second adhesive area 23 (not visible in Fig. 1 ) with a permanent adhesive.
  • Access opening 13 is die-cut along its periphery in inner package 11 such that, upon the first opening of the container 1, the blank material 19 inside the die-cut line of access opening 13 is detached from inner package 11, since blank material 19 is permanently affixed to second adhesive area 23 of adhesive label 17.
  • Adhesive label 17 extends beyond the periphery of access opening 13.
  • the level of reduction of the adhesive bond between first adhesive area 21 and first coated area 15 depends on the amount of silicone additive, wax or any other substance contained in the coating of the first coated area, which reduces adhesive bonding in first coated area 15. The higher the amount of additive, the lower the force needed to lift lid 7.
  • Fig. 3 shows a portion of the outer surface of inner package 11 with access opening 13 and first coated area 15 below access opening 13.
  • First coated area 15 is spaced apart from the periphery of access opening 13. The height of the gap between access opening 13 and first coated area 15 depends on the position of first area 21 of adhesive label 17; both areas preferably overlie each other.
  • Access opening 13 can be formed by die-cutting, perforating or through-cutting along at least three edges at the periphery; the left, right, and lower edge in Fig. 3 .
  • blank material 19 inside access opening can detach from inner package 11 at a predefined periphery.
  • Second adhesive area 23 comprising a permanent adhesive at least partially corresponds to the size and position of access opening 13.
  • second adhesive area 23 may be smaller than the size of the access opening, and more preferably may be 3 mm smaller than the size of the access opening such that blank material 19 is reliably detached from inner package 11 upon the first opening of container 1.
  • the portion of second adhesive area 23 along the edge and that in the center do not have to be connected.
  • the portion along the periphery forms a hinge area when adhesive label 17 is attached to inner package 11.
  • Fig. 5 shows the outer surface of adhesive label 17 comprising a third adhesive area 25 with permanent adhesive and an adhesive free area 27.
  • Third adhesive area 25 is attached to the inner surface of lid 7, wherein the adhesive bond between third adhesive area 25 and lid 7 enables adhesive label 17 to be peeled off and resealed when lid 7 is lifted and closed, respectively.
  • FIG. 6 another preferred embodiment of the present invention with regard to the arrangement of inner package 11 is depicted.
  • the periphery of access opening 13 can be surrounded by a second coated area 29 whose adhesive force reducing capability is less than that of first coated area 15. Due to second coated area 29 it is possible to provide the inner surface of adhesive label 17 just with second adhesive area 23 comprising a permanent adhesive, as shown in Fig. 7 . Consequently, the manufacturing of adhesive label 17 is simplified.
