LABEL FOR WET APPLICATIONS

Abstract

A label for a bottle where the label is comprised of a laminate where an outer layer (3) is a material susceptible to losing opaqueness when made wet, and an inner layer (5) behind this first layer which is a material that is opaque, and such that it will maintain such opaqueness when wet.

Claims

1. A label of laminate construction, comprising: an outer layer for receiving printed indicia on an exposed surface thereof; and an under layer attached to the outer layer, the under layer being attachable to a surface, wherein the outer layer is made of a material that has an opacity, wherein the opacity of the outerlayer material reduces after the outer layer is exposed to moisture or liquid, and the under layer is made of a different material that has an opacity, wherein the opacity of the under layer material, after exposure of the under layer to moisture or liquid, is configured not to be affected in the same manner as the opacity of the outer layer material, and wherein the outer layer is adhered to the under layer.

2. The label as in claim 1, wherein the under layer is white,

17. A label for a bottle wherein the label is a laminate, comprising: an outermost layer upon which there is printed indicia; and a lower or more inner layer that is coupled between the outermost layer and the bottle, wherein the outermost layer is made of a material that has an opacity that reduces after the outermost layer is exposed to moisture or liquid; the lower or more inner layer is made of another material that has another opacity that is substantially unaffected by exposure of the lower or more inner layer to moisture or liquid.

18. The label as in claim 17, wherein the lower or inner layer is an innermost layer.

19. The label as in claim 17, in which the lower or inner layer is a plastics material.

20. The label as in claim 17, wherein the laminate has each layer of the laminate joined to adjacent layers by water insoluble means or materials.

21. The label as in claim 20, wherein the water insoluble means are a fusion of plastics material with a respective adjacent layer.

22. The label as in claim 17, wherein the label is secured to an outermost surface of the bottle, wherein the innermost layer of the laminate is adhered directly onto an outer surface of the bottle with substantially water insoluble means or material, and wherein the outermost layer is positioned to be outermost with respect to the bottle so as to display the printed indicia thereon.

23. The label as in claim 17, wherein the outermost layer is paper.

24. The label as in claim 1, wherein the under layer is a film of plastics material.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] For a better understanding of this invention it will now be described with relation to a specific embodiment which will be described with the assistance of drawings wherein

[0040] FIG. 1 is a perspective view of a bottle to which a label is attached and

[0041] FIG. 2 is a cross-sectional view along the lines 2-2 in FIG. 1.

[0042] FIG. 3 is a cross-sectional view of further embodiment of the invention.

[0043] The challenge has been to provide a label that has an uncoated surface that provides for many, a preferred surface appearance and texture.

[0044] However, uncoated paper is inherently vulnerable to absorption of water and the results of inundation either simply by condensation, or inundation of water are such that it creates then an appearance that is not preferred.

[0045] This appearance includes a change of colour and the effect can be somewhat irregular.

[0046] Also, there is a problem that such wetting will cause the paper to differentially swell or contract.

[0047] We firstly therefore adhered to the back of uncoated paper a plastics material film

[0048] This then acted to hold the uncoated paper when they were inundated together but the appearance still had the irregular change in colour, which looked much less desirable.

[0049] By having a plastic film, which could also be opaque adhered to the back of the uncoated paper, substantially reduced this difficulty.

[0050] Especially then if the colour of the film was white, this then provides the dual benefits of both providing a secure holding together of the uncoated paper material as well as an appearance that, even when the uncoated paper is saturated, does not change its appearance substantially, and maintains therefore a significantly improved appearance over what was the case hitherto.

[0051] Referring specifically to the drawings there is therefore a bottle 1 to which is adhered a label 2. The label 2 is made as a laminate with an outer layer 3, which is an uncoated paper, and this is adhering through a glue 4 to an inner film 5 which is the plastics material. The glue 6 may or may not be the same as glue 4.

[0052] In a further embodiment of the invention, and with reference to FIG. 3, the outer layer 3 is applied directly onto a sheet of extruded plastics material 5. This then results in the bonding of the label to the plastics material without the need for any adhesive. Such techniques are well known to those skilled in the art. The resulting product can then be attached to a bottle 1, or other container, by way of a glue 6. In the printing of labels, a stock is therefore provided where for instance the label is to be a self-adhesive label, that has an uncoated upper layer and an effectively permanent adhesive which is then glued to an underlying plastics material film which in this case is a biaxial orientated polypropylene.

[0053] In this case this is manufactured as a five layer extruded film with a cavitated inner core for opacity and stiffness.

[0054] The colour of the film is white and it had a sufficient opaqueness so that it has an optical density greater than 0.54 as measured by a Tobias densitometer.

[0055] The stock material is supplied when in a self-adhesive format on a glassine backing which is then supplied for application to containers.

[0056] It would be well understood by a person skilled in the trade that the backing may differ according to certain applications or preferences and may well include PET backing, KRAFT backing or other such backing without departing from the scope of the invention.

[0057] In the case of wine, this is therefore to glass bottles, and the advantage of the invention is especially apparent for glass bottles, which have a lighter or fully transparent colouring and character.

[0058] The label according to this invention can then be applied in the traditional way from the glassine backing onto bottles.

[0059] It is considered that any of a number of plastic materials can be selected for this application and these can be for instance polyethylene film, non-orientated polypropylene film, or PET film.

[0060] In order to have a sufficient opacity, in each case, such a film would be either filled with an appropriate filler giving it a sufficient opacity for the purpose or it can be tinted again to be sufficient to provide the effective purpose.

[0061] While an indication of opacity has been given, the degree of opacity that is useful in any case can be established by very simple experiment and it would not be intended in the broadest sense that the degree of opacity should be necessarily constrained to the specific reference given.

[0062] Throughout this specification the purpose has been to illustrate this invention and not to limit this.
