An improved distal end for a ligating band dispenser having a transverse groove or ridge profile that promotes rolling of the bands. In one embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is substantially the same as the pitch of the transverse grooves or ridges. In another embodiment, the ligating bands and the transverse grooves or ridges are dimensioned such that the width of the bands when stretched on the support surface is less than the pitch of the transverse grooves or ridges. Having the width of the bands when stretched on the support surface be substantially the same as or less than the pitch of the transverse grooves or ridges allows the bands to fit within the grooves, which helps insure that the bands are sufficiently held back by the ridge crests to induce a rolling action. In addition, the transverse grooves or ridges may also be dimensioned such that the height of the ridge crests is sufficiently high to insure that the bands are sufficiently held back by the ridge crests to induce a rolling action.

The invention relates to a package for ready-prepared foods, which comprises a dish (1) containing packed food that has been cooked in the dish, and a lid heat- sealed to the rim flange (2) of the dish. Upon cooking grease lands onto the rim flange, the detriment of which caused to the sealing has in the invention been prevented by providing the rim flange with elevated ridges (3, 4) so that, upon closing the dish, a gastight sealing line is formed between the lid and the ridges. According to the invention the rim flange has two or more concentric longitudinal ridges (3) circulating the dish and transverse ridges (4), by means of which the space between two longitudinal ridges (3) has been divided into at least five compartments for diminishing the possibility of sealing leakages. In practice there can be considerably more compartments, suitably 10-200. The dish can be made of polymer- coated cardboard, the rim flange of injection-moulded plastics and the lid of polymer-coated paper so that a closure making possible the pulling off of the lid is produced during heat-sealing.
