Description

~ WO95/11833 ~1 7 3 8 ~ 6 PCT/GB94/02170 l APPARATUS AND METHOD FOR LABELLING CONTAINERS USING
2 THERMAL BONDING

4 This invention relates to apparatus used for applying labels to containers. The invention has a particular, 6 although not exclusive, application in connection with 7 machinery encompassing roll-fed labelling apparatus.

9 Roll-fed labellers commonly comprise means for supplying labels to a vacuum drum which, in turn, ll offers the labels to containers housed on an adjacent 12 rotating turret. The labels, which initially are in 13 the form of a continuous web, are fed through a series 14 of rollers including, for example, a standard cutter and pinch roller, which cuts the web at appropriate 16 lengths in order to provide separate labels. The 17 labels are held to the vacuum drum by a vacuum means 18 before each are released to a respective adjacent l9 container upon which they are intended to be applied.
2l The containers may be of any type, and are generally 22 those used for cont~ining food or beverages. The 23 containers are mounted in chucks attached to the turret 24 and are adapted to rotate about an axis parallel to the WO9~/11833 ~ t~6 PCT/GB9~/02170 l turret axis, about which the turret itself rotates.
3 In the past it has been known to attach the labels to
4 the containers by various methods. Such methods include the use of adhesives or glues, hot melt 6 techniques/ water adhesion and the like. However, a 7 disadvantage of these known methods of securing labels 8 to their respective containers is that their use ~ frequently causes damage or marking to the containers.
This obviously has detrimental implications when it is ll sought to recycle the containers. A similar 12 disadvantage results when removal of the label from the 13 container, which is required during recycling, causes 14 similar marking or damage of the containers.
16 It is therefore an object of the invention to provide a 17 means of attaching labels to containers, particularly 18 in connection with roll-fed labelling apparatus wherein l9 the container is not potentially marked or damaged by the attachment method. The invention seeks to 2l accomplish this object by causing the label to form a 22 sleeve which snugly circumnavigates the containers;
23 having the leading and trailing edge of the label 24 jointed to each other, as opposed to the container.
26 According to the invention there is provided a label 27 having a leading edge and a trailing edge, wherein one 28 or both of said edges include a thermally activated 29 adhesive material.
31 Preferably, the thermally activated adhesive material 32 is printed onto said label.

34 Also, according to the invention there is provided apparatus for applying a label as described above to a ~ wo 95,llg33 2 ~ i ~ 8 ~ PCT/GB94/02170 l container, said apparatus including a heating means 2 adapted to induce thermal bonding of the leading edge 3 to the traii-ng edge of the label once the label has 4 circumnaviga_ed the container.

6 Preferably, the heating means comprises electric 7 elements.

9 Preferably, said apparatus includes a vacuum drum and said electric elements are housed within said drum.

12 Alternatively, the heating means comprises a heat lamp 13 located in juxta-position to the location where said 14 thermal bonding of the leading edge to the trailing edge of the label is required to be effected.

17 Alternatively, the heating means wherein the heating 18 means uses heat derived from frictional losses in l9 moving parts of the apparatus.
2l A method of applying a label to a container, the method 22 comprising causing the label to circumnavigate the 23 container, jointing a leading and trailing edge of the 24 label to each other so as to form a sleeve about the container, wherein the label is not chemically fixed to 26 the container.

28 Preferably, the method of jointing of the leading and 29 trailing edge of the label utilises thermal bonding.
31 In order to enable a better understanding of the 32 invention, an example embodiment will now be described 33 with reference to the accompanying drawings:-Fig. l which is a plan view of a turret housing a WO95/11833 ~ 6 PCT/GB94/02170 O

l plurality of containers to which are offered 2 labels from a vacuum drum; the vacuum drum 3 incorporating electric h~ating elements.
Apparatus as may be found in a roll-fed labelling 6 machine comprises a turret l which is rotatable about a 7 fixed axis 2. The turret is adapted to support a 8 plurality of containers 3 which, in the em~odiment 9 shown, are cylindrical plastic bottles. In use, the turret l rotates in a clockwise direction about its ll axis 2. The bottles or containers 3 are also rotatably 12 mounted by chucks (not shown). The chucks allow the 13 containers 3 to spin in an anti-clockwise direction 14 about their centre axis.
16 The apparatus also includes a vacuum drum 4 which is 17 adapted to rotate about the axis 5 and comprises 18 suction means for holding labels 6 thereto as it l9 rotates. The vacuum drum is adapted to rotate in a clockwise direction about its axis 5 in use.

22 A series of rollers 7 supply the labels 6 to the vacuum 23 drum 4. The rollers 7 include a standard cutter and 24 pinch roller 7a which cuts the web of labels 8 into a plurality of individual labels 6. The labels 6 26 supplied to the drum 4 are inherent with a thermally-27 activated adhesive material positioned along the 28 leading edge and trailing edge of each respective label 29 6. This material may be inherent in the label material itself or, alternatively, may be applied as a coating 31 in a print run while the labels are in web form before 32 being applied to the roll-fed labelling apparatus.

34 In use, the vacuum drum 4 offers a label 6 to a respective container 3. The leading edge of the label ~ WO9~/11833 2 } 7 ~ ~ ~ 6 PCT/GB94/02170 s l 6 is taken up by the container and this may be 2 accomplished using any applied or naturally occurring 3 bonding medium such as glue, water, static electricity 4 or the like. Methods of this type are known in the art. The label 6 is then encouraged to wrap around 6 said container 3 by the combined rotation of the turret 7 l, container 3 and vacuum drum 4.

9 The trailing edge of the label 6 is then secured or otherwise attached to the leading edge of the label ll through the use of the thermally-activated adhesive 12 material inherent in the label 6. The adhesive 13 material is, in fact, thermally-activated by heating 14 elements 9. In the embodiments shown, the heating elements 9 are housed within the vacuum drum 4.
16 However, the invention is not limited to such an 17 embodiment and the heating elements 9 may, for example, 18 alternatively be in the form of heat lamps or the like.
l9 What is essential to the invention is that a heat source is provided which causes the thermally-activated 2l adhesive material located at least at the leading or 22 trailing edge of the label to be activated. It is 23 realised, however, that the heat of the vacuum drum or 24 other apparatus previously included in roll-fed labelling apparatus may be cleverly employed to provide 26 thermal activation means.

28 Once the trailing edge of the label 6 is adhered to the 29 leading edge of the label 6 there is provided a sleeve which surrounds the surface of the container. The 31 effect of this is that the bottle or container 3 does 32 not itself receive any glue, adhesive or hot melt 33 directly on its surface of necessity. This will 34 depend, of course, on the means used of causing the label to circumnavigate the container prior to the .

WO9S/11833 2 1 73~36 PCT/GB9~/02170 l leading and trailing edge of the label 6 being adhered 2 together. It is realised in the invention that it is 3 advantageous, when it is desired to recycle the 4 container and remove the label, to avoid using an adhesion means which contacts both the label and 6 container as this can lead to marking or damage of the 7 container itself.

9 The invention described hereinbefore provides a means of applying a label to a container such that the label ll is in the form of a rolled-on sleeve with minim~l or no 12 bonding required between the bottle and the label.
13 This has the advantage of allowing the label to be cut 14 from the bottle with the bottle thereafter being recycled in an undamaged state and, secondly, 16 eliminating or reducing the extent of glue consumables 17 or application equipment being required. This latter l~ aspect of course reduces the capital and running costs lg of the apparatus required to perform this process of production.

22 Further modifications and impLov~ nts may be 23 incorporated without departing from the spirit or scope 24 of the invention herein intended.
