A method of and device for applying foil to a container that has a closure over its upper surface, and especially to a bottle with a head that along with its cap is to be wrapped all the way around with a blank, especially of foil, by applying the blank around the head while leaving part of the blank to project beyond it, wrapping the sleeve-shaped extension to one side against the upper surface of the cap to create an outer cap cover, and pressing it down, especially with a resilient pad. To improve the method and device of the aforesaid type to the extent that it becomes possible to press the sleeve-shaped foil extension down over the upper surface of the cap optimally single-layered and wrinkle-free and hence to employ pre-printed foil, a flute that initially extends essentially parallel to the axis of the bottle is shaped into the sleeve-shaped extension while the latter is being wrapped and is tapered out from the lip of the bottle to the peak of the extension with the folded areas of the two sides of the section that has been shaped into the flute coming to rest essentially outside the upper surface of the cap.
In a method of applying foil to a bottle with a head that along with its cap is to be wrapped all the way around with a blank of foil, by applying the blank around the head while leaving part of the blank to project beyond the head, wrapping a sleeve-shaped extension of the blank to one side against an upper surface of the cap to form an outer cap cover, and pressing the sleeve-shaped extension down, a resilient pad, the improvement comprising shaping the sleeve-shaped extension while it is being wrapped to form a flute that initially extends essentially parallel to the axis of the bottle, expanding and flattening the flute until it contacts the cap and flattening the foil to form two folded areas that extend from two sides of the flute and terminate essentially outside the upper surface of the cap.
In a device for applying foil to a bottle with a head and cap to be wrapped, having means for transporting bottles in a path, a foil-application station positioned alongside the path traveled by the bottles for transferring blanks of foil to the bottles to form a sleeve-shaped extension, at least one wrapping component positioned over the head of each bottle for acting on the sleeve-shaped extension, and at least one component disposed at an upper surface of the cap to apply pressure to the blank, the improvement wherein the at least one wrapping component comprises a triangular saddle shaped element with one apex pointing, along with an adjacent, symmetrically poitioned rear portion toward a downstream end of the sleeve-shaped extension for shaping a flute into the extension, the flute extending essentially parallel to the axis of the bottle.
