Description

[Detailed description of the invention] The present invention relates to a label tape.

Label tapes have been developed in recent years, particularly those in the form of embossed tapes, which have found extremely wide use in home and office applications. Particularly successful are the types widely sold under the Dymo trademark.

Such label wording tapes are used in simple hand-held machines in which the tape is fed between two embossing dies that are pressed together to emboss the desired character form onto the tape. This is done successively for each character of the desired legend, and a small piece of tape with the desired legend is then cut. The tape consists of two layers held together by a tacky pressure-sensitive adhesive, and after cutting a small piece of tape with the desired markings, one layer is peeled back to expose the adhesive, which is then used. Another layer of the label is then applied to the desired surface.

Although such tapes have been extremely well received in the 911 class, they are not without drawbacks. Therefore, in order to make the embossing possible given the appropriate thickness of the material, it is necessary to make the tape itself quite thick and the embossing thick enough.The label is therefore glued The embossed letter will protrude undesirably from the surface to which it is attached, and will catch on, for example, the edge of paper or the fibers of cloth that cross the surface to which it is attached. It appears white on a dark base, i.e. it appears in opposite contrast when compared to the labels printed on Atsushi.This does not aid rapid perception of the Japanese language.

British Standard No. 728545 describes another tape that can be used for label words.

The tape of British Patent Specification No. 72 '8545 comprises a transparent nJ flexible layer with a pressure sensitive recording layer thereon, the recording layer concealing any layer below it, and generally Beneath this there is a base layer, which is provided with an adhesive for adhering to the desired substrate. When such a tape is applied with pressure, for example by writing or by typewriter method, it is sensitive to The pressure recording layer material changes or disintegrates through the recording layer along the line of the pressure stroke to expose the contrasting color of the underlying layer.The complete structure is then labeled for labeling. The resulting label is therefore very susceptible to damage or deterioration, for example by accidental application of pressure, causing unintentional changes or disintegration of the pressure-sensitive recording layer material.

A first feature of the invention includes a label tape comprising an image-donating tape that is held against a captured image-receiving tape;
The image-donating tape consists of a plastic film backing having a peelable dyed or pigmented coating on the side adjacent to the image-receiving tape, which when pressure is applied to the rear surface of the image-donating tape in the image direction. The image-donor tape adheres more strongly to the image-receiving tape than to the backing, and in which the image-receiving tape is adhesively adhered to the release film by means of a layer of pressure-sensitive adhesive of permanent tack. consisting of an image-receiving flexible plastic film,
The image-donating tape is then narrower than the image-receiving tape and each side is held against the image-receiving tape.

When using the label word tape according to the present invention, the desired label Japanese language can be changed to the desired language, such as letters or numbers,
A pressure corresponding to the shape is created continuously by suitably applying pressure to the rear surface of the image-receiving tape. This causes the removable colored or dyed coating to transfer from the plastic film backing of the image-donor tape to the area where pressure is applied to the flexible plastic film of the image-receiving tape. The appropriate length of tape is usually cut when the desired label inscription is completed. To adhere the label as desired to the support, the release film was removed and the remaining one-electrode donor film was removed and discarded and transferred into the peeled colored or dyed coating phase. The flexible plastic film of the image-receiving tape with the markings thereon is left adhered to the support.

The tape according to the invention can thus be used in a manner similar to known embossed tapes to provide labels. However, since the image-receiving tape can be made extremely thin, and the image-donor tape can apply a thin but highly opaque layer under the action of pressure, the finished label is thin and thin. Therefore, it can be easily removed, for example by mechanically hooking it onto a cloth or paper edge.1. Additionally, since the remainder of the image tape is removed and discarded and does not form part of the final label, accidental pressure is applied. The chance of scratches or fluctuations is reduced.

Although the detailed composition of the image-receiving tape according to the present invention may vary, it has properties similar to the so-called carbon film resin used in modern electric typewriters. They generally consist of a very thin plastic film backing with a black-colored coating on one side, which adheres firmly to the inner film during handling, but nevertheless under the influence of pressure. The image is first transferred to the desired support.

The image-receiving tape, as described above, consists of a tape of plastic film releasably adhered to, for example, a tape of release paper or release coated film. The film may be transparent or translucent, or may be eg opaque white or black. A preferred image-receiving film is a transparent cellulose acetate, preferably having a matte or semi-matte surface so that the perimeter of the final label is less noticeable, especially when the label is applied to the final support. The pressure sensitive adhesive that attaches it to the release paper or release coated film is preferably of the acrylic type, although many other permanent tack pressure sensitive adhesive types can be used. A preferred material for the backing of the image-receiving tape is siliconized release paper. .

The image-donating tape can be held against the 11', 1 wide one-sided receiving tape by applying a further layer of adhesive tape over it and adhering this to the image-receiving tape at the end overlapping the image-donating tape. can. Adhesives should of course be chosen so that they do not leave any residue on the image-receiving tape when removed, and are preferably suitable for labels such as glass, metal, paper, paperboard, plastic and wood. It is chosen to have a peel bond value to its surface that is less than that of the permanently tacky pressure sensitive adhesive forming part of the image-receiving tape for most of the supports to be applied. Alternatively, the image-donor tape consists of a single backing having a streak of dyed or pigmented peel-off coating extending downward from its center and whose edges are coated with two layers of pressure-sensitive adhesive. can do. Such materials are generally more difficult to manufacture and therefore this alternative is less preferred.

The labeling tapes according to the invention can be made in one piece on standard tape embossing machines, where the female dies are buried so that in each case they provide a flat anvil surface for pressure application. The tape advancement and tape cutting mechanisms for advancing the tape when continuing to make character images on the tape and for cutting the portion of the tape where the image is pressed are available from machine sales and special J [ It is well known from the literature and therefore will not be described further here.

However, it is preferred that the tape be cut into arcuate tapes rather than in straight lines, since doing so will facilitate the separation of the used image-providing tape later on from disposal, and the separation will not occur when the tape is already separated. This is easily accomplished at the convex end of the label.

Thus, when using the tape according to the invention, it must be of a known type and modified as described above, inserted into the tape receptacle or cartridge of a tape applicator machine, and then subsequently selected characters. Apply the desired Japanese words, move them to the desired position on the tape and apply it against the tape under pressure, the label strip with the desired Japanese words then cut out and remove the release paper or tape1. A layer of pressure sensitive adhesive is then applied to the desired receptor. The image-donor tape used can be removed at this stage if it has not been removed previously.

Preferably, the donor tape is left on top until after the image-receiving tape has been applied, since this prevents the newly transferred image-bearing material from being rubbed with an overzealous finger, for example, to fix it. This is to avoid the risk of getting it dirty. Of course, in such circumstances one should not rub with sufficient pressure to cause anything undesirable or to transfer the colored layer from the surface-donating tape to the image-receiving tape.

Referring now to the drawings, the labeling tape according to the invention consists of a siliconized bleached kraft tape 1 and a 60 μm thick cellulose acetate film adhered thereto by means of a layer of acrylic pressure sensitive adhesive 3. tape 2
Consists of.

Holded against the tape 2 by means of a similar tape consisting of a 30 μm Jl cellulose acetate film 4 and an acrylic adhesive 5 is a polyethylene film backing with a black colored coating γ on one side thereof. The adhesion of adhesive 5 to the acetate film 2 is generally weaker than the adhesion of adhesive 3 to a support such as paper, glass or metal to which it is desired to apply the label. The coating 7 under the action of pressure applied from the top as seen in FIG. Therefore, if the tape 4 is peeled off from the tape 2 after application of such a localized pressure blob, e.g.
and the remainder of the colored coating I is removed, leaving on the top of the acedate film 2 an area of coating 7 which constitutes the desired image. This can be done before or after adhering the label to the desired surface by peeling off the release paper 1 and applying a coat of adhesive 3 to harden the label underneath.

The following examples will serve to demonstrate the invention: Example 6 A 0 μm thick cellulose acetate film was coated with the following coating composition using a Meyer bar: Niacrylic polymer Contact agent (National 0301026 with 40% N, V,
