Abstract

PROBLEM TO BE SOLVED: To reliably peel each label from the beltlike base paper of a label strip and to prevent the tear of the base paper from a break in the base paper in the peeling by forming slits in the base paper along part of the edges of etch label when a plurality of labels are temporarily stuck to the beltlike base paper at prescribed intervals to obtain the label strip. SOLUTION: When labels 3 are temporarily stuck to beltlike base paper 8 at prescribed intervals to obtain a label strip 1a, perforated line-shaped slits 9 are formed in the base paper 8 along the front edge 3a of each of the labels 3 in the peeling direction of the labels (F1 direction). The length of the slits 9 are arbitrarily determined but the slits 9 must be formed in such a way that the beltlike ground paper 8 is made less liable to tear in the peeling of the label chips 3. Thus the length of the slits 9 is appropriately 1-5 mm and non-slit parts 9a are preferably made longer than the slits 9.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label continuum to which label pieces are temporarily attached, and more particularly to a label continuum having improved releasability when the label piece is peeled off from a backing paper.

[0002]

2. Description of the Related Art In general, a conventional label is prepared by temporarily attaching a label material having a pressure-sensitive adhesive layer to a backing paper having a release agent layer. In the manufacture, a band-shaped label material, usually made of high-quality paper, is temporarily attached to the band-shaped backing paper, and the label material is cut (die cut) at a predetermined pitch, and a plurality of single leaf label pieces are placed on the mounting board at predetermined intervals. To form a label continuum.

FIG. 5 is a partially cutaway cross-sectional view of a label continuous body. The label continuous body 25 has a release agent layer 4 formed on the front side of the backing sheet 2 and a back side of the label piece 3. Has a pressure-sensitive adhesive 5 formed thereon. In manufacturing the label continuous body 25, a method is employed in which a cutting blade (not shown) is pressed off from the front side of the label material toward the mount 2. That each label piece 3 cannot be obtained unless the pressure-sensitive adhesive layer 5 is completely cut;
Furthermore, since the pressure-sensitive adhesive layer 5 of the label material and the release agent layer 4 of the backing sheet 2 are very thin, a cut groove 6 such as a scratch or a cut may be formed on the surface of the backing sheet 2 during cutting. Therefore, as shown in the drawing, the pressure-sensitive adhesive 5 enters the cutting groove 6 along with the cutting operation, and the label piece 3
May be impaired from the backing paper 2.

FIG. 6 is a schematic explanatory view of a peeling section for peeling a label piece. When the label piece 3 is mechanically peeled from the backing paper 2, the label piece 25 is transferred in the F direction. Then, the backing sheet 2 is bent at the leading end of the peeling section 7 to peel off the label piece 3 from the backing sheet 2. In the label continuous body 25 as described above, the pressure-sensitive adhesive 5 is attached to the backing sheet. 2, the label 3 was not peeled off because the peelability was lowered.

Thus, Japanese Patent Application Laid-Open No. 57-109974 can be cited. Japanese Patent Application Laid-Open No. 57-109974 discloses a proposal in which a tongue-shaped cut having a flat U-shaped or V-shaped shape extending from the lower surface of a label piece to the outside of the label piece is engraved on a separator (backing paper). In the case of peeling by a machine (labeler), a technique for easily and reliably performing a peeling action is disclosed.

However, since the tongue-shaped cut is made, when the label piece is peeled off from the separator, when the traction force for pulling the backing sheet or the transfer speed of the label continuous body when peeling the label piece is high, Since the backing sheet is further torn from the end of the tongue-shaped cut, the backing sheet is peeled off in a state where the backing sheet is partially attached to the peeled label piece, and a problem of poor peeling occurs.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is intended to ensure that the label is peeled off when the label is peeled off from the backing sheet, and that the backing sheet is cut from the cut of the backing sheet at the time of peeling. Provide a label continuum that does not tear.

[0008]

According to the present invention, there is provided a label continuous body in which a plurality of label pieces are temporarily attached at predetermined intervals to a band-shaped backing paper, wherein a slit is formed in a part of a label edge portion of the label piece. It is a label continuum characterized by the following.

[0009] In the label continuous body, the slit is formed in a perforated shape.

[0010] In the above label continuous body, the slit is formed on the front edge of the label of the label piece when the slit is transferred in the direction of peeling the label piece.

[0011] In the label continuous body, the slit is formed at a label corner of the label piece when the slit is transferred in a direction in which the label piece is peeled off.

Therefore, by forming the slit along the label edge portion of the label piece, the bite of the pressure-sensitive adhesive is reduced, and the releasability is improved from the slit portion. Can be easily peeled, so that it can be surely peeled off and can be prevented from being torn from the slit portion. Also,
When the slit is formed in the label corner of the label piece, the peelability of the corner of the label piece is improved, so that the label piece is easily peeled from the corner and is reliably peeled.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

A perforated slit 9 is formed in the band-shaped backing sheet 8 along the label piece front edge 3a in the label piece peeling direction (the direction F1 in FIG. 1) of the label continuous body 1a. I have. Although the length of the slit 9 in the present embodiment is arbitrarily formed, it is necessary to form the strip-shaped backing sheet 8 so that it is difficult to tear when the label piece 3 is peeled off. It is better that the non-slit portion 9a is formed longer than the slit 9.

FIG. 2 is a partial plan view of a label continuum 1b shown as a first modification of the present invention. The label continuity 1b has label pieces 3,... ing. A slit 11 is formed in the band-shaped backing material 10 along the label corner 3b of the label piece 3 in the peeling direction (the direction of arrow F2 in FIG. 2) in which the label piece 3 of the label continuous body 1b is peeled. The slit 11 is formed along the label corner 3b, that is, in an L-shape. The slit 11 of the first modification is formed continuously in an L shape, but may be divided into a slit in the width direction of the band-shaped backing sheet 10 and a slit in the longitudinal direction of the band-shaped backing sheet 10. is there. In this case, label corner 3
A non-slit portion is formed at the corner of b.

FIG. 3 is a partial plan view of a label continuum 1c shown as a modification 2 of the present invention. In the label continuity 1c, label pieces 3,... ing. Label continuum 1c peeling direction (arrow F3 in FIG. 3)
A slit 13 is formed in the mount 12 at a substantially middle portion of the front edge 3c of the label piece 3 in the direction (direction). Modification 2
The slit 13 is formed along the front edge of the label piece and is located in the middle of the band-shaped backing paper. Further, a suitable length of the slit 13 is such that the slit 13 of 1 mm to 5 mm is formed.

The operation of the continuous label body in which the slit is formed in the band-shaped backing sheet will be described with reference to a peeling device. In addition, it demonstrates as label continuous body 1a. FIG. 4 is a schematic explanatory view of a peeling device for peeling off a label piece of a continuous label body of the present invention, and the peeling device 20 includes a supply unit 14, a peeling unit 15,
It comprises a winding unit 16.

The supply section 14 is provided with a supply shaft 17 for rotatably holding a roll-shaped label continuum obtained by turning the label continuity 1a into a roll. The label continuity 1a fed out of the roll-shaped label continuation is It is transferred to the peeling section 15.
The peeling portion 15 is provided with a peeling plate 18 for turning the band-shaped backing sheet 2 to peel off the label pieces 3. The strip-shaped backing sheet 2 from which the label pieces 3 have been peeled off is transported and wound on a winding shaft 19 provided in the winding section 16.
The winding shaft 19 is driven by a driving source (not shown).
