FR2753292A1 - Double adhesive label, e.g. for pharmaceutical products - Google Patents

Abstract

A double adhesive label, e.g. carried on a continuous backing strip (14), consists of a lower label (10) made from a layer of material (16) which is pressure printed, has a coating of adhesive (18) on the back and an anti-adhesive coating on the front. The lower label is covered by an upper one (12) with an adhesive coating (22) on the back, while information printed on the front is duplicated on the lower label. The lower label's adhesive is designed for permanent fixing, while the upper label can have a tongue for easy lifting. During use the lower, permanent label is attached to a container, while the upper one is used for record purposes.

Description

DOUBLE ADHESIVE LABEL
The subject of the present invention is a double label, in particular for use on the packaging of pharmaceutical products.

 We know that the problem of labeling and information is crucial for certain products and more particularly for medical products. Indeed, it is necessary to mark the name of the different drugs contained, this directly on the containers to avoid any error, especially when there is a mixture of products.

 We note that often nothing the products are dissolved in liquids and the whole remains limpid and without particular color.

 Very often, the medical personnel note at the time of the mixing or the transfer on a file the reference of the product (s). This poses the problem of transfer errors first of all and when it is necessary to write on a bottle, the problem of the support. This support is often reduced to a piece of duct tape and a marker writing on the tape.

 It is certain that the search for traceability of treatments or quality is impossible under such conditions.

 In manufacturing, the products have a name, manufacturing dates, expiration dates, batch numbers, references such as a trademark and / or a barcode for production monitoring.

Certain information must therefore be printed at the time of manufacture or packaging, such as dates or batch numbers, while other information, such as name, trademark, may be printed beforehand.

 We also know that the label supplier may be different from the conditioner, so that it may be interesting to offer a finished label to the conditioner but capable of being supplemented at the time of packaging by additional printing.

 It is the object of the present invention to provide such a label which, moreover, is a double label superposed to allow the lower label to remain on the original packaging while the upper label is peeled off and affixed to a other packaging or on any other document.

 Of course, superimposable detachable adhesive labels are known, such as those described in patent application FR-A-2 038 779.

 Variable dimensions of the different superimposed labels allow the label to appear immediately below when the upper label is removed.

 Such labels relate to the problem of gripping and / or viewing the number of superimposed labels remaining but do not solve the problem of marking at the time of printing or deferred at the time of packaging.

 In application FR-A-2 705 061, a bundle of sheets is described comprising cutouts, these cutouts making it possible to detach part of the sheet which then constitutes an adhesive label. The invention relates to the distribution of the adhesive and silicone zones enabling these labels to be detached. Some sheets may be carbonless.

 The superimposition of labels from patent application EP-A-285 514 comprises an adhesive label disposed on a strip support from which it can be extracted to be pressed definitively on a support.

This label includes carbonless non-adhesive labels superimposed and retained on the lateral edges only, with lateral precuts facilitating the separation of these labels one by one or all together when they are multiple.

 Patent application NL-A-83 01508 describes a superimposed double label, the upper label of which is removable, but this label is entirely pre-printed without the possibility of additional printing or marking. Although seeking to answer the problem posed, this request does so only partially.

 Also the present invention provides a double adhesive label, more particularly for the pharmaceutical industry, characterized in that it comprises a first lower label comprising a sheet printed with means to make it carbonless under pressure, the back of which is coated with a layer of glue and the front of which is coated with a non-stick layer, and a second label comprising a printed sheet whose back is coated with a layer of glue and the front of which can receive information by marking generating sufficient mechanical pressure to ensure the copying of said information on the first label.

 More particularly, the two sheets are printed separately in an identical manner before their superposition.

 Specifically, the adhesive layer of the first label is of high adhesive power for final fixing.

 The second label includes a tab to facilitate its removal from the first label.

The invention is described below according to a particular, non-limiting embodiment, with reference to the appended drawings in which there is shown
- Figure 1, a perspective view of a label according to the invention in
partially stripped position,
FIG. 2, a view in longitudinal section, and
- Figures 3A, 3B and 3C, the implementation of the label according to
the invention.

 In FIG. 1, the superimposed double label comprises a first label 10 and a second superimposed label 12, the first label being carried by a strip 14 of non-adhesive material such as a strip of silicone paper.

 In the sectional view of FIG. 2, the complex proposed by the present invention comprises in detail the non-adhesive support strip 14 and the two labels 10 and 12 which are of different natures.

 Indeed, the sheet 16 of the first label 10 comprises on its back a layer of adhesive 18, with high adhesive power. This layer of adhesive cannot adhere to the support strip, but it can be fixed to almost any support, including glass, even that which has been treated to withstand impacts in the packaging lines.

 The sheet of paper 16 of the first label is particular since it is coated on the front with a film making it non-adhesive so that the second label 12 can be peeled off.

 This sheet is also special in the sense that it is carbonless as symbolized in the drawing by microspheres.

 The second label 12 comprises a sheet 20, the back of which is coated with an adhesive 22 of the repositionable type or with direct bonding, but the adhesive power of which is weaker than that of the first label.

 This sheet can receive a manual writing using a rigid instrument to transmit the pressure on the second label or by mechanical printing.

 A tab 24 is shown in Figures 1 and 2, it simply facilitates the gripping of the second label, this in known manner.

 In FIG. 3A, the complex removed from the support strip 14 is affixed to a bottle 26. This complex bears the imprints printed on each of the labels, strictly identical and corresponding to specific and invariable expressions.

 The high power of the adhesive layer 18 allows a final fixing of the complex on the bottle, as shown in FIG. 3A.

 In FIG. 3B, information 28 is marked on the complex, more precisely on the front of the sheet 20 of the second label.

 This information is reproduced by pressing on the first sheet.

 In FIG. 3C, it can be seen that the first label 10 remains stuck on the bottle 26 with the carbonless mention of the information 28 ′ and that the second label 12 can be removed to affix it to another support 30, this label with the original mention of the information 28.

 Of course, this information 28 can be printed in second printing during packaging, on the finished complex, itself composed of the two labels printed and treated adequately as indicated above.

 So the information is well worn at the last moment but most of the label is already printed which is important because the print quality is always better than that achieved with a carbonless system.
