Description

The present invention relates to a sealing label, and more particularly to a sealing label for sealing an envelope or the like.

The conventional sealing label 1 will be outlined with reference to FIGS.
FIG. 13 is a plan view of the sealing label 1, and FIG. 14 is a cross-sectional view taken along the line XIV-XIV of FIG. 13, and the sealing label 1 includes a mount 2 and a label substrate 3.
The mount 2 has a release agent layer 4 formed on the surface side thereof.
The label base material 3 has a pressure-sensitive adhesive layer 5 formed on the back surface thereof, and is temporarily attached on the mount 2 so that the pressure-sensitive adhesive layer 5 faces the release agent layer 4.

In particular, as shown in FIG. 14, a pair of left and right cut lines by perforations that extend from the label base material 3 to the mount 2 and extend in the length direction at a predetermined interval in the width direction of the label base material 3. 6 is formed.
By applying a varnish or other non-adhesive agent to the adhesive layer 5 between the pair of cut lines 6 to form a non-adhesive layer 7, a non-adhesive central removal at the center of the label substrate 3 is performed. An area 8 is formed, and an affixing area 9 for the label base material 3 is formed adjacent to the left and right of the central removal area 8.
A semicircular removal knob 10 is formed on at least one end of the central removal region 8 (the left end in the example shown in FIG. 13).

    15 is a plan view showing a state in which the label base material 3 is attached to the envelope 11 and sealed, and FIG. 16 is a cross-sectional view taken along the line XVI-XVI of FIG. Thus, the envelope 11 is sealed by attaching the label base material 3 to the folding lid 12 so that the center removal region 8 covers the edge 12A of the folding lid 12 of the envelope 11.

    FIG. 17 is a cross-sectional explanatory view similar to FIG. 16, showing a state in which the central removal region 8 has been removed when opening the envelope 11, and by pulling with the removal knob 10, non-adhesive central removal is performed. By separating the region 8 from the pair of left and right label base materials 3 (the pasting region 9), the folding lid 12, that is, the envelope 11 can be opened.

However, in particular, as shown in FIG. 16, in the state where the label base material 3 (a pair of pasting regions 9) is stuck to the envelope 11, the adhesive layer 5 at the boundary portion by the tear line 6 is in the central removal region 8. So that the non-adhesiveness at the back end portion is lost, and the central removal region 8 is lost because the soaking portion 5A covers the back end portion of the central removal region 8. There is a problem in that when the envelope 11 is removed and the envelope 11 is opened, the central removal region 8 cannot be peeled off.
Further, there is a problem that the folding lid 12 or the envelope 11 itself is torn when the central removal region 8 is cut along the cut line 6.

This can be formed so that the mount covers the adhesive layer between the lines.

    The non-adhesive layer can be formed by not forming the adhesive layer on the back surface of the label substrate.

    The adhesive of the adhesive layer can form the central removal region and the non-adhesive layer by straddling the cut line and not forming it on the back surface of the label base material.

    At the time of sealing, the label base material is attached to the envelope so that the central removal region covers the folding lid portion of the envelope.

In the sealing label according to the present invention, a pair of left and right non-adhesive layers adjacent to the central removal region, positioned along the respective cut lines and on the outer edge side in the width direction of the label base material from the respective cut lines. Is formed on the back surface of the label base material, so that the possibility of the adhesive layer entering the central removal region can be eliminated, and when the envelope is opened, the central removal region can be separated and removed from the pasting region easily and easily. The tear line can be easily cut.
