  • Patent number: 4753384
    Abstract: Hinge-lid packs for cigarettes or other pack contents are very expensive in respect of material consumption. A saving of material is achieved as a result of bevelled longitudinal edges (26,27) and lid longitudinal edges (28,29), while preserving the storage capacity, because, in particular, side tabs (31,32) and lid side tabs (33,34) of the side wall (13) and of the lid side wall (18,19) are made with less width and hence save material.

  • Patent number: 4730766
    Abstract: This relates to a carton or cup having a conventional type of gable end which includes sealing flaps which are heat sealed or bonded to one another. The cup is particularly adapted to be closed by hand wherein control over the sealing flap positions is not possible as in the case of machine closed cups. Accordingly, the intermediate folded sealing flaps are so configurated wherein the folded ends thereof will be spaced so as to define therebetween a leak path. One of the front and rear sealing flaps will be provided with a bead of hot melt material which will be aligned with the leak path and when the sealing flaps are heat bonded together, the hot melt material will melt and fill the leak path.
