Definitions

• the invention relates to a bottle or the like with a circumferential label according to claim 1, a method and an apparatus for producing such a bottle according to claims 11 and 23, and a label or label tape for wrapping a bottle according to claim 30.
• the invention has for its object to provide a bottle with a label enveloping the bottle, a label or label tape and a method and an apparatus for improved, more powerful and more reliable label removal.
• the label enveloping the bottle is provided on the upper and / or lower edge with at least one line of weakness oriented essentially transversely to the circumferential extent of the label, the length of the line of weakness being less than the label height.
• the label Because of this weakening line starting from the edge, the label has a predetermined breaking point at which it quickly tears when exposed to fluid jets for the purpose of removing the label. As soon as the tear in the label which is favored by the line of weakness arises, the label can subsequently continue through the fluid jets torn all the way to the opposite edge of the label, making it much easier to remove the label. Label removal can also be carried out in a shorter time with increased functional reliability.
• the line of weakness is not formed continuously from the upper to the lower label edge over the entire label height, but the length is preferably only a fraction of the label height, the strength and extensibility of the label surrounding the bottle is largely preserved in the circumferential direction.
• This property of the label is particularly advantageous in the case of elastic plastic bottles, since their diameter can increase when the bottle is heated, especially if the bottle is filled with a liquid containing CO 2. With the proposed solution, undesired tearing and chipping of the label at the consumer is avoided. Furthermore, the visual appearance of the label is hardly impaired if the length of the line of weakness is kept to the minimum required. This minimum depends on various factors, such as the label material and its thickness, the bottle properties (hard or elastic) and the execution of the line of weakness.
• a weakening length of a few centimeters is sufficient.
• a length of 10 to 30 millimeters is sufficient for label films made of oriented polypropylene (OPP). It is advantageous to attach a plurality of weakening lines spaced apart from one another in the circumferential direction at the edge of a label, because this means that no alignment of the weakening line with the fluid jets or relative rotation of the bottle and the fluid jets during label removal may be necessary. Furthermore, the distance security can be further increased with this configuration.

• a plastic beverage bottle 1 is shown, which is equipped in the trunk area with a label 2 surrounding the entire circumference of the bottle.
• This label can be designed as a preformed sleeve, which is cut, for example, from a film tube and pulled over the bottle, or as an all-round label, which is wrapped around the bottle circumference and in the overlap area of the label start and end edges is connected, for example by means of adhesive, solvent, by heat sealing or welding.
• Various methods and machines for producing both types of equipment are already known (DE 32 08 234 C2, EP 0 525 729 B1).
• the special feature is that the label 2 is provided on the upper edge 5 with short perforation lines 7 running transversely to the circumferential extent, which facilitate later removal of the label 2 from the bottle 1.
• the perforation lines 7 can be provided on the lower edge 6 or simultaneously on both edges 5 and 6.
• the arrangement of the perforation lines 7 depends on the design of the label removal machine with which the bottles are to be treated later.
• the length of the perforation lines 7 arranged at the upper edge 5 is only a fraction of the label height and that several perforation lines 7 are spaced apart in the longitudinal direction of the label blank. In the present case, there are four perforation lines 7 for each label blank 2 available.
• the perforation lines can be attached during the production of the label tapes or label tubes or in connection with the detachment of the individual cuts from a tape immediately before application to a bottle.
• the perforation lines could be generated, for example, with a controlled laser or high-pressure water jet.
• FIG. 3 shows a labeling machine for processing a label tape 21 which is pulled off a roll 20.
• the machine shown has a continuously rotating turntable 15, which has rotatable plates 16 which are arranged on a pitch circle 36 with a uniform spacing and which can be controlled.
• the bottles 1 are supplied and removed in a manner known per se by an inlet star wheel 17 (not shown in more detail) and an outlet star wheel 18, the pitch circles of which touch the pitch circle 36 of the rotary table 15.
• a bottle guide bend 19 is arranged between the inlet and outlet star wheel.
• the turntable 15 there is an upper part (not shown), which rotates synchronously with the turntable 15 in the correct position and which has a plate which can be raised and lowered in a controlled manner for axially clamping a bottle 1 between a plate 16 and the associated centering bell. Seen in the direction of rotation of the rotary table 15, one is stationary in the area behind the inlet star wheel 17 Spray nozzle 30 positioned to wet the outer surface of the bottles 1. For example, ionized steam or water can be used to moisten the bottles 1.
• a liquid adhesion promoter (adhesive) can also be applied to the passing bottles, which preferably has the property that after removing a label from a labeled bottle, it adheres to the back of the label material essentially without residues on the bottle wall.
• the bottles 1 can be rotated about their vertical axis by means of the controlled plates 16.
• the bottles 1 are then guided by the turntable 15, with simultaneous rotation about their vertical axis, past a stationary labeling unit 9 which has a vacuum drum 14 rotating in the opposite direction to the bottles 1.
• This vacuum drum 14 is preceded by a cutting device consisting of a fixed knife 12 and a rotating vacuum knife drum 13.
• a pair of feed rollers 22 and 23 which can be driven in opposite directions, the film strip 21 is pulled off the supply roll 20 and fed to the cutting device mentioned.
• the feed roller 23 is equipped on its outer surface with a perforation knife 40, which is arranged in height on the feed roller 23 such that the label tape 21 passing between the feed rollers 22 and 23 is provided with perforation lines 7 at its upper edge.
• the feed roller 22 can be equipped with a hard rubber jacket and forms the Counter surface for the perforation knife 40.
• the cutting device 12, 13 separates individual labels 2 with a corresponding length from the film strip 21 in such a way that the leading label leading edge 3 a first slider 10, which can be controlled radially from the periphery of the vacuum drum 14, and the trailing label end edge 4 a second , is also assigned radially pilot controllable slide 11.
• a rotating glue roller 8 for gluing the label end edge 4 is arranged at a small intermediate distance from the periphery of the vacuum drum 14. With the radially controllable second slide 11, the label end edge 4 can be brought into contact with it when passing through the glue roller 8, as a result of which a narrow, vertical glue strip 39 (FIG.
• an ion spray bar 38 for electrostatically charging the label 2 can be arranged at an intermediate distance on the circumference of the vacuum drum 14 immediately before or during the transition from the vacuum drum 14 to a bottle.
• This ion spray bar has numerous metal tips, not shown, distributed along its longitudinal extent, the longitudinal extent of the ion spray bar 38 running essentially parallel to the axis of rotation of the vacuum drum 14. The metal tips of the ion spray stick face the inside of the label.
• the adhesive is applied to the label end edge 4 before the label is loaded.
• the ion spray rod 38 can deviate from the 3 with its metal tips oriented radially to the circumference of the vacuum drum 14. In this case, it is advantageous to use a vacuum drum 14 consisting of an insulating material or insulated from the machine frame.
• the use of the aforementioned spray nozzle 30 on the turntable 15 may be dispensed with.
• Finishing process neutralized existing loads from the label and the bottle.
• the unloading is supported by rotating the bottles about their vertical axis. After leaving the outlet star wheel 18, the neutralized bottles 1 can be touched safely.
• the labeling machine shown in FIG. 3 can be equipped with heat sealing tools.
• the heat sealing tools can, for example, be arranged radially within the pitch circle 36 on the turntable 15, corresponding to FIGS. 1 and 2 of the European patent 0 525 729. In connection with the electrostatic label transfer to the bottles 1 described above, completely glueless labeling can be done in this way will be realized.
• FIG. 4 shows the feed roller pair 22 and 23 in a side view.
• a perforation knife 40 is fastened to the circumference of the feed roller 23 in such a way that the label tape passing through the gap between the two rollers is perforated at the upper label edge 5, as a result of which lines of weakness 7 arise (see FIG. 2).
• the height of the perforation knife 40 can be adjusted relative to the label tape 21, for example by axially displacing the feed roller 23 along its drive shaft, or using interchangeable feed rollers 23 with different lengths or differently arranged perforation knives 40 or needles.
• perforation tools can be omitted if an already pre-perforated label tape 21 is used.
• the lines of weakness can already be created during label production.
• the lines of weakness can be generated by a locally reduced thickness of the label material. Such weakening lines can also be provided during label production.
