Definitions

  • the present invention relates to a label for a container and to a method and apparatus for making a label, and in particular to a label which is intended to be stuck on to a container such as, for example, a box, packet, bottle or tin.
  • the present invention provides a label for a container comprising two superposed webs of sheet material which are adhered together at two regions spaced from each other, there being between those regions two opposed inner web surfaces, at least one of which carries printed information, at one of the said regions the two webs being releasably adhered together so that the two webs can be separated thereby to reveal the information by pulling the webs apart in that region.
  • the present invention further provides a method for making labels in a continuous process, comprising the steps of:-
  • the present invention further provides an apparatus for making labels in a continuous process, comprising a first printing station for printing information on a side of a first elongate web of sheet material, a second printing station for printing information on a side of a second elongate web of sheet material, means for superposing the two printed webs and adhering the two printed webs together so that the webs are adhered together at a succession of regions spaced from each other along the composite web so produced each or every other of those regions including a portion at which the two webs are releasably adhered together and there being between successive pairs of those regions two opposed inner web surfaces, at least one of which carries printed information, and a cutting device for cutting the composite web so as to produce labels, each label including a pair of the opposed inner web surfaces and incorporating two of the adhered regions, one of those regions having a respective one of the portions.
  • printing is to be construed in its broadest sense to include printing processes, such as, for example, gravure, lithography, letterpress, flexography, and screen printing.
  • a label 2 consists of two strips 4, 6 of a sheet material such as, for example, paper.
  • the two strips 4, 6 have substantially the same area and are preferably rectilinear (e.g. rectangular) in shape.
  • the two strips 4, 6 are superposed over each other so that one strip 4 constitutes an upper strip, the front surface 8 of which is visible when the label 2 is affixed to a container, and the other strip 6 constitutes a lower strip, the rear surface 10 of which is to be affixed to the container.
  • the two strips 4, 6 are attached together at two regions 12, 14 which are spaced from each other and extend across the width of the strips 4, 6 at a respective end thereof.
  • Dctted lines 16, 18 in Figure 1 show an edge of the respective region 12, 14, each region 12, 14 being defined at its other edges by the edges of the strips 4, 6.
  • the strips 4, 6 are composed of paper, they may be attached by means of a layer 20, 21 of a suitable adhesive, such as, for example, a water-based adhesive, which layer 2C, 21 extends across the respective region 12, 14.
  • the label 2 can carry printed information, such as textual infonration, concerning the product in the container, on the front surface 8.
  • the two opposed inner surfaces 22, 24 of the label carry further printed information. In order to render visible the two inner surfaces 22, 24, the two strips 4, 6 are separated so as to open the label 2 in the manner which is described hereinbelow.
  • the front surface 8 of the label 2 carries a high quality lithographically-printed image.
  • upper strip 4 is provided with a band 26 of a material which renders the paper hydrophobic, thereby to allow the upper strip 4 to be selectively detached from and re-attacred to the lower strip so as to be able repeatedly to open and close the label 2.
  • the band 26 is preferably co-extensive with the adhesive layer 21 in region 14 and the arrangement is such that the adhesive layer 21 cannot contact the upper strip 4 directly but only via the band 26.
  • the material which renders the paper hydrophobic is a polysiloxane such as, for example, a polysiloxane manufactured under the code name WS7CM and WS78L by Wacker and sold in Great Britain by Ambersil Limited, Basingstoke, Hants. as Silicone Fluid FIOO.
  • a polysiloxane manufactured under the code name WS7CM and WS78L by Wacker and sold in Great Britain by Ambersil Limited, Basingstoke, Hants. as Silicone Fluid FIOO.
  • a polysiloxane such as, for example, a polysiloxane manufactured under the code name WS7CM and WS78L by Wacker and sold in Great Britain by Ambersil Limited, Basingstoke, Hants. as Silicone Fluid FIOO.
  • the adhesive layer 21 consists of a water - borne pressure sensitive adhesive, such as an acrylic copolymer pressure sensitive adhesive.
  • a particularly preferable adhesive is an adhesive sold by National Adhesives, of Slough, Berkshire, United Kingdom, under the trade name Nacor 360.
  • One disadvantage of using a polysiloxane is the tendency of the polysiloxane to migrate or spread by capillary action along the fibres in the paper across the paper surface. Hitherto, due to that tendency to migrate, materials such as polysiloxanes have been considered only for applications where the polysiloxane is to be spread over a large area on a surface of a material such as paper where the edges of the polysiloxane layer are defined by the edges of the material itself. In the past, due to the migration of the polysiloxane it has proved difficult to define on the surface of a paper web the edge of a layer of polysiloxane. The migration tends to reduce the resealability of the label and results in the band 26 being messily formed on upper strip 4.
  • a further disadvantage of using polysiloxane is that it is generally difficult to achieve satisfactory resealability, especially when the label is to be opened and closed a number of times.
  • the formulations of the adhesive and of the polysiloxane must be closely controlled so as to provide sufficient adhesive strength of the adhesive and sufficient hydrophobic strength of the polysiloxane in order to provide a sufficiently strong and resealable bond.
  • the material which renders the paper of the label hydrophobic consists of a mixture of a polysiloxane, such as that described above, and a varnish.
  • the varnish is an overprinting varnish of the type which is in common use in the printing industry.
  • An example of such a varnish is an overprinting varnish made by Fishburn and having the code name XF 05546.
  • the mixture contains from 90 to 99.5 vol % polysiloxane and from 0.5 to lC vol % varnish, the percentage values being based on the total volume of the mixture.
  • the incorporation of the varnish into the polysiloxane substantially overcomes the above-described two disadvantages of polysiloxane.
  • Second, the resealability of the label is improved since the presence of the varnish tends to enhance the adhesion of the adhesive 21 onto the upper strip 4, even after the label has been opened and closed a number of times.
  • the amount of varnish should preferably not exceed lC vol % of the volume of the mixture otherwise there is a tendency for the adhesive 21 to adhere too firmly to upper strip 4 which can result in the label being torn when opened.
  • the amount of varnish should preferably not be less than 0.5 vol % of the volume of the mixture otherwise the effect of the varnish is not significant and migration of the polysiloxane can occur and the resealability of the label is reduced.
  • the label 2 may be any desired size and shape and may be composed of any suitable sheet material e.g. paper, plastics sheet, etc.
  • the plastics sheets may be attached by heat sealing.
  • the band 26 and the adhered layer 21 could be provided instead on the lower strip 6 and the upper strip 4, respectively.
  • the band 26 does not have to be positioned at the edge of the label 2.
  • adhesive layer 21 and band 26 may be disposed inwardly of an edge of the label 2 so as to provide an unadhered region, between that edge and the band 26/adhesive layer 21 adhered region, in which the two strips 4,6 can readily be separated manually prior to pulling apart that adhered region.
  • the band 26 should be at least coextensive with the adhesive layer 21. If desired, as shown in Figure 4, a number of the labels 2 may be carried in succession on a length of release backing material 40 which for convenience of handling can be wound into a reel.
  • the reel When subsequently labelling containers, the reel can be unwound so that the labels 2 can be removed successively from the backing material 40 and applied to containers to be labelled.
  • the backing material 40 may be composed of a waxed paper sheet.
  • the labels 2 can be removably attached to the backing material 40 by providing on the rear surface 1C a layer of pressure-sensitive adhsive so that the label 2 is self-adhesive.
  • FIG. 5 An apparatus and method for making the labels 2 will new be described with reference to Figure 5.
  • the apparatus shown in Figure 5 is employed to make the labels 2 in the form shown in Figure 4, in which a number of the labels 2 are carried an a release backing material 40.
  • a first reel 42 comprises a wound-up web 44 of self-adhesive paper on a release backing material.
  • the release backing material is on the lower side of the web 44.
  • the web 44 is fed out from reel 42 to a first printing station 46 comprising a pair of cylinders, one 48 being a print cylinder and the other 50 being an impression cylinder.
  • textual information is printed at successive positions along the length of the web 44 in one colour on the upper surface of the paper.
  • the printed upper surface of web 44 is to constitute the inner surface 24 of the labels 2.
  • adhesive applying station 52 comprising a pair of cyliners, one 54 being an adhesive applying cylinder and the other 56 being a backing cylinder.
  • adhesive applying station 52 may comprise an adhesive extruder for extruding adhesive onto the web 44.
  • Adhesive is applied to desired areas in successive postions along the length of the web 44, those areas being between the successive printed areas on the upper surface of the paper so as to form the adhesive layers 20, 21 which are shown in Figure 2.
  • continuous layers of adhesive can be applied at successive positions along the length of the web 44, each layer being defined by lines 16 and 18 and the edges of the web 44.
  • the two separate regions 20, 21 are formed from each said layer, each region 2C, 21 being associated with a respective label 2.
  • the web 44 is then fed to a pair of nip rollers 58.
  • a second reel 60 comprises a wound-up web 62 of paper.
  • the web 62 is fed successively along a plurality of printing stations 64, each of which comprises a respective pair of cylinders and at eacr of which textual information is printed onto a side of the paper at successive locations along the length thereof. Beth sides of the paper are printed.
  • the upper surface of web 62 is to constitute the upper surface 8 of the labels 2 and the printed lower surface of the web 62 is to constitute the inner surface 22 of the labels 2.
  • the printed web 62 is then fed to a further pair of cylinders 66.
  • the cylinders 66 apply to the lower surface of the web 62 at successive positions therealong between the printed areas the band 26 of hydrophobic material, the band 26 being transverse to the web 62.
  • the web 62 is then fed to the nip rollers 58.
  • the nip rollers 58 squeeze the two webs 44, 62 together so that they are stuck together by the adhesive layers 20, 21. There is precise longitudinal alignment of the two webs 44, 62 so as to ensure that when the subsequent labels 2 are produced, the printed inner surfaces 22, 24 are fully visible when the label 2 is opened and the band 26 is correctly aligned with that layer of adhesive which is to constitute layer 21 in the resultant label.
  • a combined web 68 emerges from the nip rollers 58 and is then fed to a die cutting station 70, comprising a die-cutting cylinder 72 and a backing cylinder 74. At the die-cuttig station 7C, the individual labels 2 are cut out by cutting through both of the continuous paper sheets. The release backing material is not cut and the resultant die-cut web has an appearance similar to that shown in Figre 4. The excess paper 76 is taken off continuously and wound into a reel 78. The die-cut web is wound into a reel 80.
  • the label 2 When the upper strip 4 of the label 2 bears on its upper surface 8 a lithographically printed image, the label 2 is not made by the apparatus and method which are described with reference to Figure 5, since the upper strip 4 must be applied as an individual sheet bearing a lithographically printed image rather than as a web.
  • the label 2 having the lithographically printed image may however be made by the method and apparatus which are disclosed in my British Patent Specification No. 2122968 published on 25th January 1984 the disclosures of which are incorporated herein by reference.
  • Each of the individual lithographically printed sheets to constitute upper strip 4 has the band 26 of hydrophobic material applied thereto prior to being adhered to lower strip 6.
  • the support web (which is to constitute the lower strip 6 of the labels 2) to which the individual lithographically printed sheets are adhered is coated with a succession of spaced bands of adhesive and then the lithographically printed sheets are applied in succession to the bands of adhesive so that in each resultant label each lithographically printed sheet is adhered by two layers 20,21 of adhesive, with the layer 21 of adhesive being in registry with the band 26 of hydrophobic material.
  • the individual labels are then cut out in the release backing material as described in that specification.
