  • the retaining tabs 19a and 19b will assist in the closure of the pack and will prevent a bundle of smoking articles from sliding completely out of the pack body.
  • each side flap 18a and 18b has a reinforcing flap (20a and 20b) depending from an opposing (bottom) marginal edge. In the assembled pack the reinforcing flaps 20a and 20b are folded against the inner surface of the bottom panel 12. In this way, the bottom of the pack is reinforced against crushing forces.
  • the fold lines are foldable to form a sharp, single edge to the pack formed from the depicted pack blank 1. Alterntive embodiments are envisaged wherein the fold lines are formable into a plurality of angles and the pack formed from the respective blanks may have one or more square, rounded, bevelled or elliptical edges.
  • the second major panel 14 has a recess 21 in a transverse edge.
  • the recess 21 is in the form of a C-shaped section cut out of the second major pane! 14 of the body portion 3 of the pack blank 1.
  • the depth dimension of the recess 21 is the same as the length dimension of the front panel 5b of the closure portion 5 of the lid 2.
  • the distance from the fold line 8 interconnecting the top 5a and front 5b panels of the closure member and the removable portion 6 measured perpendicular to that fold line is substantially equal to or marginally more than the depth dimension of the recess 21.
  • Figure 3 depicts a pack formed from the pack blank 1 of Figure 1 prior to first opening by the consumer.
  • the lid When the lid is closed, as illustrated, the top panel 5a abuts retaining tabs 19a, 19b and the front panel 5b is retained flat against the outer surface of the second major panel 14 to cover the recess 21.
  • the second section of the front panel 5b together with the removable portion 6 and the edge portion 4 are also retained flat against the outer surface of the second major panel 14.
  • the retaining force is provided by adhesive (not shown) applied to the pack- facing surface of the edge portion 4 which adheres to the outer surface of the second major panel 14.
  • Figure 4 depicts the pack of Figure 3 after first opening by the consumer (but with its contents removed for clarity).
  • a consumer may open the pack by pulling the tear strip 6 with either a tool or by hand to progressively separate it along perforations 11, 12 and completely remove it from the pack.
  • the adhesive force between the edge portion 4 and the outer surface of the second major panel 14 is greater than the force required to rupture the perforations 11, 12 such that the edge portion 4 becomes separated from the front panel 5b of the lid and remains adhered to the pack.
  • the top and front panels 5a, 5b of the lid may then be pivoted along fold line 7 (shown in Fig. 2) to facilitate access to the contents of the pack by the consumer.
  • this arrangement provides the consumer with visual evidence of first opening of a pack.
  • the lowest edge of the front wall 5b of the closure portion may be tucked inside the front major panel of the pack so that the pack may readily be opened and closed whilst the contents are being consumed.
  • the second section of the front panel of the lid forms a tongue which may be pushed into the recess in the second major panel so as to re-close the pack.

Abstract

L'invention concerne une découpe de paquet d'articles à fumer et des paquets formés à partir de cette découpe. En particulier, l'invention concerne des découpes et des paquets portant une indication destinée au consommateur, ladite indication indiquant la façon d'ouvrir le paquet pour la première fois. Le paquet est constitué d'une matière non plastique, ce qui permet de faciliter sa mise au rebut. Le paquet comprend une partie couvercle (5a, 5b) et une partie (14) appartenant au corps du paquet. La partie couvercle comprend une partie bord (4) et une partie fermeture (5b), chacune de ces parties étant reliée par une partie amovible (6), notamment une bande déchirable. La partie bord (4) se superpose à une face principale (14) du paquet et est fixée sur cette face par voie adhésive. Pour avoir accès au contenu du paquet, le consommateur doit retirer la bande déchirable (6) en la déchirant le long de lignes prédécoupées (10, 11) pour détacher la partie fermeture (5b) de la partie bord, la partie bord restant collée au paquet (voir fig.4). La partie fermeture peut alors être glissée à l'intérieur de la face principale (voir fig.5) pour permettre l'ouverture et la fermeture du paquet pendant la consommation de son contenu.
