Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a multi-layer label, for example, a multi-layer label which is attached to products placed in various processes of distribution channels and used for their management. Regarding labels.

(Prior art) For products placed on distribution channels, for example, factory shipment,
In order to reliably grasp the status of shipment, inventory, sales, returned goods, etc. at each stage of wholesale, retail, etc., each product is labeled with a display label showing its content, date, product number, etc. .

As such a display label, in recent years, for example, a label with a so-called bar code, which is obtained by encoding the above-mentioned data and displaying it as a print form suitable for computer processing, is gradually used. Such a bar code or the like is read by an optical reader for each individual product in each of the above-mentioned steps, and the recorded data is later provided to a totaling process by a computer or the like.

(Problems to be solved by the invention) The above-mentioned bar code and the like are displayed directly on the product packaging or on the label surface affixed to the product. Although the reading of the bar code has been simplified in recent years, it is still a troublesome work, and there is a risk of misreading due to stains or discoloration of the display label when the product is transferred through various routes.

Therefore, it is desired to provide a display label that is relatively easy to read the display contents and processes the data and has few errors.

(Means for Solving Problems) The problem of the conventional technology is that the thermosensitive coloring of each display label is formed by a laminate of two or more display labels each having a thermosensitive coloring layer as a display area formed on the surface thereof. The thermosensitive coloring temperature of the color forming layer is the highest in the uppermost color forming layer of the laminate and is gradually decreased for each layer, and the thermoplastic synthetic resin in a molten state is provided between adjacent display labels. A multi-layer display label is characterized in that a composite resin layer, which is detachably bonded by being supplied to the film surface of a different thermoplastic resin having a higher melting point and then cooled and solidified, is interposed.

(Operation) In the multilayer label of the present invention, the label of each layer is sequentially peeled off from the laminate of the label as required. Therefore, for example, in the case of a display label in which a bar code or the like is printed in the display area of the label, even if the bar code of the display label attached to each product is read by a reader or the like on the spot as in the conventional case. Alternatively, the uppermost display label may be simply peeled off and stored for each specific distribution stage, and later, these may be collectively processed efficiently such as reading and counting.

As the heat-sensitive color-developing layer, a material capable of color-printing with a normal thermal printer is used, and the heat-sensitive color-developing material of each layer has a higher heat-sensitivity (lower color-developing temperature) in the lower layer of the laminate. It is set.

Various means can be used for peelably laminating a plurality of display labels.
It is preferable to use a so-called pseudo-adhesion (lead adhesion) between different kinds of synthetic resin films disclosed in No. 29 or the like in which a mutually separable composite resin layer is interposed between the respective display labels.

Here, "lead adhesion" means that when a specific thermoplastic resin is extruded in a molten state onto the film surface of another type of thermoplastic resin and then cooled and solidified, the so-called wetting between the two makes the bonded surface easy to peel (180 ° peeling). Strength: 10 to 20 g / cm) refers to a state in which they are temporarily attached to each other.

When the composite resin layer thus obtained is bonded between the adjacent upper and lower display labels in the laminated body of the display label by an ordinary adhesive means such as a pressure-sensitive adhesive, each constituent layer of the composite resin layer The display labels in the upper and lower layers can be peeled from each other by easily peeling the tapes on the lead bonding surface, if necessary.

In the case of the composite resin layer, the surface of the constituent layer after separation is not sticky as in the case of using an ordinary pressure-sensitive adhesive, so that the display label after peeling is extremely easy to handle.

Since the multi-layer display label of the present invention is usually affixed to an object to be displayed, it is usually applied to the back surface of the display label of the lowermost layer, and an adhesive for application is applied and combined with a silicone release paper or the like. It is preferable.

In order to smoothly peel off the labels of the respective layers from the laminated state, it is preferable to form a peeling margin by providing a step at the laminated end between the respective layer display labels. Such a stripping allowance can be simultaneously performed, for example, in a working process using a normal die roll when half die cutting each display label on a release paper surface.

The shape of the display label may be arbitrary, and a laminate of the individual display labels may be arranged at a predetermined interval on a continuous long release paper, and may be attached to an object with an auto labeler or the like. In addition, depending on the application, the laminate of the display labels may be separated at predetermined intervals in the longitudinal direction so as to be separable by perforations or the like to form individual multilayer display labels.

Example 1 As shown in FIG. 1, a die temperature of about 310 ° C. was provided between a polyethylene terephthalate film (hereinafter referred to as PET film) 7 having a thickness of about 25 μm and a polyethylene film (hereinafter referred to as PE film) 5 having a thickness of about 20 μm. Molten polyethylene resin (hereinafter referred to as PE) is poured, and both films 5 and 7 are lead-adhered through the PE bonding layer 6 that is cooled and solidified to form the composite resin layer 4.

Here, the PE bonding layer 6 is partially compatible with the PE film 5 when melted and is firmly integrated, but the PE bonding layer 6 has a peel strength of about 10 g / cm due to so-called lead bonding. Easy to peel off.

The upper surface of the PE film 5 of the composite resin layer 4 and PET
The lower surface of the film 7 is adhered to the display labels 2A and 2B provided with the thermosensitive coloring layers 1A and 1B by pressure sensitive adhesive layers 8 and 8 respectively, and a multi-layer (two layers in the illustrated example) display label 3
Is formed. Silicon release paper 9 is combined with the back surface of the lower label paper 2B via a pressure sensitive adhesive layer 8.

When the laminated body shown in FIG. 1 is actually mass-produced, the display label paper 2A and PET with the PE film 5 adhered on the back surface are used.
It is also possible that the PE in a molten state is poured between the film 7 and the film 7 and the pressure is narrowed by a pressure roller, and then the label paper 2B of the next layer is adhered to the back surface of the PET film 7. In this case, it is preferable that the roller on the side of the display label paper 2A be provided with an appropriate cooling means so that the coloring layer 1A does not develop color due to heat from the molten PE.

In the multi-layer display label 3, sequential peeling between the upper label label 2A and the lower label label 2B and between the lower label label 2B and the release label 9 is reliable and easy. Display label paper 2A, 2B
The stripping margins 10A and 10B are formed at one of the laminated end portions, and a step is provided between them.

When thermal printing is performed on such a multilayer display label 3 by a printer head of an ordinary thermal printer, the display area of the thermosensitive coloring layer 1A of the upper display label sheet 2A and the thermosensitive coloring layer of the lower display label 2B. The same bar code BAR as shown in FIG. 2 is thermally printed on the display area of 1B.

In this case, the coloring layer 2A of the display label paper 2B below the laminate
Since the color development temperature (60 ℃) is set lower than the color development temperature (70 ℃) of the color development layer 1A of the upper label sheet 1B, the temperature due to the heat transferred from the printer head decreases in the stack. Even so, the degree of thermal color development of both color forming layers is substantially the same. A temperature of 50 to 60 ° C. may be preliminarily applied from the back side of the label by a heat roll or the like in order to assist the thermal coloring of both layers.

When using, the label sheets 2A, 2
The label laminate having the thermosensitive coloring layer on B is removed from the label laminate on the back surface, and the laminate is adhered to the surface of a desired adherend with a pressure sensitive adhesive 8.

For example, at the shipping stage from a factory, the bar code BAR of the uppermost display label 2A is sequentially read by a reader, and the record is later input to a computer and processed as data such as shipping amount and date.

Next, instead of reading the bar code BAR of the display label attached to each product with a reader at a specific stage in the distribution route, for example, at the collection / delivery center, the top label paper 2A is stripped.
Only the work of stripping from the step of A and collecting the bills is performed, and the respective uppermost layer labels thus collected are collectively read by the reader later and subjected to computer processing.

The same BAR as the bar code corresponding to each other is printed on the lower layer display label paper 2B and the peeled layer display label paper 2A attached to the adherend, for example, from a distribution center to a wholesaler or retailer. From the factory, save the upper layer display label 2A with the same content as the lower layer display label 2B affixed to the item to be delivered to the store, and read it together with the reader later. It is possible to always clearly understand the relationship between the shipment amount of the product and the delivery amount to the retail store.

For products delivered to retail stores, etc., it is possible to manage the arrival and inventory by reading the bar code BAR of the display label paper 2B at the bottom of the product, as well as the corresponding products at the factory, distribution center, etc. Correspondence with the reading record of the display label paper makes it possible to easily check the distribution status of the product.

In this case, since an ordinary adhesive is not used for bonding the upper and lower display label sheets 2A, 2B, the display label after peeling is extremely easy to handle,
Further, since the surface of the lower label sheet 2B on the adherend is covered with the transparent PET film 7, it is protected from dirt and scratches during the transfer and storage of the product.

In the above embodiment, the case where the display label paper is composed of two layers has been described, but the layer constitution may be three layers or more if necessary.

In this case, as described above, the P bonding layer 6 is used to form the P
After the E film 5 and the PET film 7 are lead-adhered, the PE film 5 is adhered to the upper-layer display label paper 2A, and the lower-layer display label paper 2B is adhered to the lower surface of the PET film 7 by repeating the procedure. The display labels can be sequentially peelably laminated.

Reference Example 1 In place of the composite resin layer 4 formed by lead bonding as described above, the inventors of the present invention disclosed in Japanese Patent Application No. 61-261660 and made an ethylene-vinyl acetate copolymer film fusion-bonded to each other for peeling. It is also possible to use various composite films.

FIG. 3 is an explanatory view showing a cross section of such a multi-layer label, the basic layer structure of which is a composite resin layer 4 composed of the constituent layers 5, 6, and 7 in FIG. The display label is the same as that of Example 1 except that a composite resin layer 14 formed by fusing EVA films 15 and 16 having a thickness of about 50 μm is used instead of the above.

The resin composite fat layer 14 is an EVA copolymer EF1010 (Asahi Kasei: MI = 1.0 g / 10, composition: vinyl acetate 10 wt%, ethylene 90 wt.
%) From a cylinder of an inflation molding machine at a temperature of about 130 ° C. to form a film having a thickness of 50 μm by inflation molding in a tubular shape, and the opposing cylinder wall films 15 and 16 are hot-bonded to each other and allowed to cool. Formed by.

Such a composite resin film 14 can be manufactured in advance by ordinary inflation molding in a mass-production form, and according to this, a composite resin film is simply laminated between the display label papers only by a laminating step of adhering the composite resin film with an adhesive. A layer indicating label can be manufactured.

Reference Example 2 Adjacent display labels are bonded with a peelable composite resin film in each of the above-mentioned Examples, but as such peelable bonding means, a weakly viscous adhesive or an adhesive and the surface are subjected to a peeling treatment. It can also be obtained by combination with a film, and FIG. 4 shows such another embodiment.

Here, the PE film 5 of FIG. 1 is omitted on the back surface of the upper label label paper 22A, and only the pressure sensitive adhesive 28 is simply applied, and the surface of the PET film 27 of the lower label paper 22B is PE. Instead of the bonding layer 7, a silicon peeling treatment layer (not shown) is formed. That is, between the upper and lower display label papers 22A and 22B can be peeled by a combination of a pressure sensitive adhesive and a silicone peeling treatment in this embodiment.

Other configurations and the basic usage of the label are the same as those in the first embodiment.

(Effect of the Invention) Since the multi-layered display label of the present invention is provided with a multi-layered display label which can be printed and displayed by an ordinary printer so as to be peelable from each other, it is possible to provide an individual label with a display such as a barcode. It is possible to perform effective data processing such as sequentially separating and collecting the display labels from the upper layer label at each specific stage of the distribution channel, and then collectively reading and recording.
