Description

Label device in particular for a champagne bottle, system and method for manufacturing such a label device.

The invention relates to the field of labels for bottles, in particular labels for bottles of champagne, wines and other spirits.

In this area, in the chain production of bottles, labels are affixed by machines to sections with curved contours. These contours mean having to stretch the label in order to affix it so that it fits the contour, for example on the shoulder of a champagne bottle.

Consequently, it has been proposed in the prior art, which can be illustrated by Figures 1 to 3, to use a support pad P on the area to be stretched Z. This pad P is produced by cutting a base support S1 protecting an adhesive face A of the label E. Thus, when the protective support S1 is removed the pellet P remains on the label E, and the pellet-label assembly is stuck to the bottle B on the production line. The S1 support and the E label are used on the B2 reel unrolled in the production line.

Unfortunately, the support S1 thus pre-cut presents weakenings in particular via holes T for cutting the pellet P. This regularly leads to breakages of the coil strips B2 in the production line, which forces production to be interrupted.

This results in a significant increase in production times, and significant human intervention which could have been avoided.

Thus, a first objective of the present invention is to propose a solution with less weakening of the labels on their support.

A second objective is to limit human intervention in the production chain.

To achieve these objectives, the invention proposes a multilayer label device comprising
- a label layer which comprises at least one label having a decorative face and an adhesive face opposite the decorative face, the label comprising an area to be stretched,
- a support pad covering the area to be stretched, and
- a support layer affixed against the adhesive face,
characterized in that the support layer forms a strip covering both the support pellet at the area to be stretched, and the adhesive face outside the area to be stretched.

Advantageously, doubling the support tablet with an additional support layer makes it possible to solidify the label device so as not to have any breakage on the production line.

This also results in a significant limitation of human intervention on the production chain, which increases productivity and efficiency.

According to one variant, the label device comprises several labels, with a support pad for each label. This makes it possible to produce a strip of labels that can be used in a bottle production line, to affix the labels to the bottles.

According to one variant, said label is a champagne bottle shoulder label. Thus, the label has a specific shape to the contours of the bottle shoulder.

The invention further relates to a label reel comprising at least one label device according to the invention.

The invention further relates to a bottle production line comprising a label device according to the invention, or a label reel according to the invention.

Another object of the invention relates to a label device manufacturing system, comprising
- a first label support strip comprising a label layer which comprises a decorative face and an adhesive face opposite the decorative face, the label layer comprising at least one area to be stretched; and a first support layer in which at least one support pellet is cut covering said area to be stretched,
- means for delaminating the label layer to separate the first cut support layer from the label layer carrying said pellet;
- means for relaminating the label layer to affix a second support layer to the label layer and to said patch so as to form a relaminated label layer.

According to a variant, the delamination means comprises a separator roller. This facilitates delamination and the formation of a coil of pierced first support layer.

Alternatively, the manufacturing system includes a pair of label layer delamination reels, and a pair of label layer relamination reels, the reel pairs having intersecting strips. This makes it possible to carry out delamination and relamination in parallel, to reduce manufacturing time and increase productivity.

The invention further relates to a method of manufacturing a label device which comprises a first label support strip comprising a label layer which comprises a decorative face and an adhesive face opposite the decorative face, the layer label comprising at least one area to be stretched; and a first support layer in which at least one support pellet is cut covering said area to be stretched, the method comprising
- a step of delaminating the label layer to separate the first cut support layer from the label layer carrying said pellet;
- a step of relaminating the label layer to affix a second support layer on the label layer and on said pellet so as to form a relaminated label layer.

According to one variant, the delamination step and the relamination step are carried out in parallel.

The invention relates to a multi-layer type label device. The label device can be in the form of a strip wound to form a reel of labels (reel B5 detailed below).

The label device includes a CE label layer. The CE label layer comprises at least one, preferably several labels E each having a decorative face D and an adhesive face A opposite the decorative face D. The decorative face D comprises for example a printed decoration to form the label E .

The CE label layer can be cut to isolate the printed E label from the rest of the CE label layer.

The paper for the CE label layer is for example Fasson® paper marketed under the name “Super White Opaque FSC®”. For example, it has 110 g/m².

In order to be able to match the contours of a mounting support such as a shoulder of a champagne bottle B, the label E also includes a zone to stretch Z. In fact, the contours and convolutions of the shoulder of the champagne bottle B may cause creases on label E once stuck to the shoulder of champagne bottle B.

To reinforce the label E at the area to be stretched Z, the label device further comprises a support pad P covering the area to be stretched Z of each label E.

In the preferred variant, the support pellet P is a sheet which may be made of material marketed under the name “glassine”. For example, it measures 138µm thick.

According to the invention, the label device further comprises a support layer S2 forming a strip covering both the support patch P at the area to be stretched Z, and the adhesive face A outside the area to be stretched Z. This becomes clear when comparing the corresponding to the prior art and the corresponding to the invention.

The reel of B5 labels thus formed can be integrated into a production line for champagne bottles B.

The invention further relates to a system for manufacturing such a label device, it is for example based on a label laminating system from the company Mida Maquina. The manufacturing system comprises a first label support strip which comprises a first support layer S1 against which a CE label layer is affixed. This first strip comes for example from a reel B1 detailed below.

Initially, the CE label layer and the aforementioned zone to be stretched Z are both covered with the first support layer S1. The support layer S1 is then cut at the zone to be stretched Z to form the support pellets P in the support layer S1, covering said zone Z. In the preferred variant, the printing of the label E takes place before the cutting of the pellet P.

Then, the CE label layer is cut, preferably after cutting the P pad.

According to the invention, the manufacturing system comprises means for delaminating the CE label layer, comprising in particular a separator roller R. The delamination means is configured to unroll the first cut support layer S1 and separate it from the layer CE label bearing said P sticker.

Furthermore, the manufacturing system further comprises a means of relaminating the CE label layer. The relamination means is configured to affix a second support layer S2 on the CE label layer and on said pellet P so as to form a relaminated CE label layer. Re-lamination is preferably carried out by rolling up the re-laminated CE label layer.

Concerning the detail of arrangement of the delamination and relamination means, this can be according to the prior art. In a particular feature of the invention, the system is configured so that delamination and relamination are carried out in parallel.

The invention further relates to the manufacture of labels, in particular for the shoulder of a champagne bottle. There illustrates the label and its position on a bottle of champagne B.

The usual manufacture of the label can be illustrated by the . This is the first part of the manufacturing within the framework of the invention.

Manufacturing is based on a first reel B1 of support S1, for example in glassine mentioned above, bearing a layer of CE label, for example Fasson® paper mentioned above.

In the illustrated variant, the manufacturing includes a printing step E1 on the decorative face D, followed by two cutting steps illustrated in detail by the .

Preferably, the first cutting step E2 concerns the cutting of the support pellet P in the support layer S1.

The second cutting step E3 concerns cutting the label around the printed part, preferably after step E2.

We therefore obtain a strip of labels E and pellets P cut on the support S1, wound into a reel (second reel B2). At this stage the label device looks like the illustration in the .

The second part of the manufacture of labels within the framework of the invention can be illustrated by the . This part is based on the second coil B2.

This second part comprises a step of delamination E4 of the CE label layer of the second reel B2, so as to unwind the first support layer S1 (cut with holes T corresponding to the pellets P) and separate it from the label layer CE carrying said pellet P. The first support layer S1 thus separated can be wound to form a third coil B3.

This second part further comprises, in particular in parallel, a relamination step E5 of the CE label layer of the second reel B2.

This relamination step is based for example on a fourth reel B4 of virgin support S2, for example of virgin glassine mentioned above.

The fourth step is carried out so as to affix a second support layer S2 on the CE label layer of the second reel B2 and also on said pellet P so as to form a relaminated CE label layer.

The relaminated strip of labels E and support S2 can be wound to form a fifth reel B5 used in the bottle B production line.
