JPH09106252A - Continuous strip of transparent labels without backing paper - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obviate the occurrence of a malfunction even if a label base material is a transparent material by applying a tacky adhesive layer applied over the entire surface on the rear surface of the transparent label base material, applying a transmission preventive layer on one side in the longitudinal direction on the front surface thereof and further, printing the front surface thereof with detecting marks consisting of non-tacky adhesives at equal intervals in a longitudinal direction. SOLUTION: The continuous strip 1 of the transport labels without backing paper wound to a roll form is constituted by applying the pressure sensitive tacky adhesive layer 3 applied over the entire surface on the rear surface side of its band-shaped label base material 2 and forming the colored transparent preventive layers 4 consisting of UV ink, UV varnish, etc., on one side of the front surface of the tacky adhesive layer 3. Further, the front surface of the transmission preventive layer 4 is printed with the detecting marks 5 consisting of UV ink, UV varnish which are equally spaced in the longitudinal direction. The front surface side of the transparent label base material 2 is coated with a release agent 6, such as silicone. The detecting marks are exactly detectable without being affected by the characters and designs on the transparent label base material at all according to this constitution.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a label printer, an automatic label sticking machine or the like, in which a sensor detects a detection mark printed on a label continuum and outputs it to printing or label sticking without a mount. A transparent label continuum.

[0002]

2. Description of the Related Art Conventionally, even a transparent label of this kind has no problem because its detection mark is generally formed on the surface of a tape-like mount on the back surface of the label. However, a problem occurs in the case of the transparent label continuous body without the usual tape-shaped mount.

[0003]

DISCLOSURE OF THE INVENTION The present invention is a transparent label continuous body without a mount, and when the label substrate is transparent,
Characters, designs, etc. already applied to the front surface of the label base material are affected by the back surface of the label base material, and the sensor that detects the detection mark malfunctions and prints to the correct position on the label or to the correct position on the article. Can not be labeled. It is an object of the present invention to provide a transparent label continuous body without a mount, which does not cause malfunction even if the label base material is a transparent body.

[0004]

In the present invention, an adhesive layer 3 applied over the entire surface is applied to the back surface of a strip-shaped transparent label substrate 2, and on this surface and at least one side in the longitudinal direction thereof. , A transmission preventing layer 4 is provided, and detection marks 5 made of a non-adhesive are printed on this surface at equal intervals in the longitudinal direction so that accurate detection can be obtained.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The following description will be made with reference to the rear view shown in FIG. 1 and the sectional view of FIG. A pressure-sensitive adhesive layer 3 applied over the entire surface is applied to the back surface of the label base material 2 of the transparent label continuous body 1 without a mount wound in a roll shape.
A non-adhesive colored permeation-preventing layer 4 such as UV ink or UV varnish is formed on the surface of and on one side thereof. Furthermore, on the surface of the permeation preventive layer 4, in the longitudinal direction,
The detection marks 5 made of UV ink and UV varnish similar to the above are printed at equal intervals.

Further, if the release agent 6 such as silicon is coated on the surface side of the transparent label base material 2, the peelability of the label is better. Reference numeral 7 is a character or design, and when the character or design is located on the detection mark 5, the sensor malfunctions.

In the present embodiment, the detection mark 5 is provided on one side of the back surface of the label base material 2, but it may be provided on both sides, and further, it is formed continuously across the width direction of the transparent label base material 2. But it's okay. Further, although it is shown as pressure-sensitive with stickiness at room temperature, it can be applied to a hot-melt type adhesive.

[0008]

As described above, according to the present invention, the permeation preventive layer 4 is provided on the surface of the pressure-sensitive adhesive layer 3 provided on the back surface of the belt-shaped transparent label substrate 2, and the detection mark 5 is further provided on this surface. Because of the printed configuration, the detection mark can be accurately detected without being affected by the characters and design on the transparent label base material.
