Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a label having no release mount for protecting an adhesive layer (label without mount), and more particularly to a coreless mountless label formed as a coreless roll paper having no core in the center.
[0002]
[Prior art]
In recent years, non-mounting labels without mounts have been used for the purpose of saving resources and reducing garbage. A label without a mount is a label made of an elongated base material having a release agent layer on one side and an adhesive layer on the other side. Since the adhesive layer of the base material on the outer peripheral side overlaps with the release agent layer of the base material, the mount (separator) can be made unnecessary. Accordingly, there is an advantage that the mount is not generated as dust after the label is used.
[0003]
The label without mount is pre-printed between the base material and the release agent layer, and only this print is used for display. Thermal paper (thermal color paper) is used as the base material so that thermal printing can be performed with a thermal printer. And a thermal transfer printing on the surface of the release agent layer using a dedicated thermal transfer ribbon.
Since these non-mounting labels are all continuous in a series of long strips, when used, they are separated by perforations (cut lines) formed on the label in advance, or by a unit provided by a cutter provided in the printer. It is designed to be used separately.
[0004]
And, as can be seen in Patent Document 1 and the like, the conventional label without a mount is wound on the outer surface of a cylindrical branch tube made of paper or synthetic resin on the outer surface of the winding base end of the label base material in order to wind it up in the form of roll. The pressure-sensitive adhesive layer is directly attached, and the branch base is rotated to wind up the label base material.

[Problems to be solved by the invention]
By the way, in the conventional label without a mount, although there is no dust on the release mount, there is still a problem that the branch tube as the winding core becomes dust after use.
[0007]
In addition, when using a conventional non-mounting label on a label printer or label applicator, the label at the beginning of the winding is directly attached to the branch pipe, so the label just before the end of one roll of label roll Has a structure that cannot be smoothly unwound, and if it is unwound to the end of the label, the label base material will be torn, the load on the printer drive system will be applied, and the stepping motor will step out. There are problems such as not being able to run at a normal pitch.
[0008]
When the branch pipe 1 is made of paper, as shown in FIG. 5, the label base material 2 may peel off the surface layer portion and be discharged from the printer. In this case, the broken label base material 2 and the fragments of the branch pipe 1 may be sandwiched between the thermal head and the platen roller of the printer, leading to a problem such as a paper jam or a paper running failure.
[0009]
Generally, a label end sensor is installed in a printer and the end mark provided on the label is detected to prevent the above problems. However, the position and shape of the end mark are not uniform for each label, and the sensor position and sensor sensitivity There was also the complication that it was necessary to adjust.
[0010]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a coreless roll paper type non-mounting label that can be used by smoothly unwinding to the end (winding start end at the time of manufacture) when the label is used. .
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the feature of the configuration adopted by the present invention is that a release mount is temporarily attached to the adhesive layer over at least the first turn on the inner winding start side of the mountless label. is there.
[0012]
According to the above configuration, the label paper without the mount is attached to the inner surface of the roll paper so that the release mount covers one or more rounds, so it can be attached without polluting the mounting shaft of the label printer, label applicator, dispenser, The core does not remain as garbage after use. Also, the label can be used without waste until the last piece.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the component same as having demonstrated with the prior art, and the description is abbreviate | omitted.
[0014]
In FIG. 2, reference numeral 10 denotes a non-mounting label according to the embodiment. The non-mounting label 10 includes a thermal paper 11 as a label substrate 2 and an upper layer side of the thermal paper 11 as shown in FIGS. 1 and 3. Is generally composed of a release agent layer 12 made of silicone or the like provided on the thermal paper 11 and a pressure-sensitive adhesive layer 13 provided on the lower layer side of the thermal paper 11.
[0015]
The thermal paper 11 is a paper base 14 coated with a thermal color former layer 15 or the like, and the thermal color former layer 15 develops characters and patterns only at the portions where heat is applied from the thermal head of the printer. And so on. Although not shown, general printing such as a frame, a pattern, and a company name may be provided on the thermal paper 11.
[0016]
As shown in FIG. 1, the non-mounting label 10 is temporarily attached to the portion on the inner winding start side of the label substrate so that the release backing layer 16 is directed toward the pressure-sensitive adhesive layer 13 and the release backing 16 is added. As shown in FIG. 4, the release mount 16 is provided with a release agent layer 18 such as silicone or polyethylene on a paper substrate 17 such as glassine paper or high-quality paper. .
[0017]
Then, the end of the release mount 16 is wound around a label winder (not shown), the release mount 16 is wound over at least one turn, and then the thermal paper 11 connected to the release mount 16 is wound, thereby releasing the release mount. A pressure-sensitive adhesive layer 13 on the back surface of the thermal paper 11 is temporarily attached onto the 16 release agent layer 18, and a pressure-sensitive adhesive of the subsequent thermal paper 11 is further provided on the outer peripheral side of the release agent layer 12 of the thermal paper 11. The agent layer 13 and the release agent layer 12 are sequentially stacked to complete the coreless mountless label 10 without a core.
[0018]
The coreless mountless label according to the present embodiment has the above-described configuration, and there is no particular difference from the conventional label in use as a mountless label.
[0019]
However, the pressure-sensitive adhesive layer 13 on the back surface of the thermal paper 11 is provided with the release mount 16 temporarily attached to the inner winding start side over at least the first turn, so that no core (core) is used. However, the pressure-sensitive adhesive layer 13 is not exposed on the inner surface of the roll paper of the label without a mount, and the mounting shaft of a label printer, label applicator, dispenser or the like that uses the label 10 without the mount is not stained. Can be installed. In addition, there is an excellent effect that the core does not remain as dust after use, and the label can be used without waste until the last piece.
[0020]
In the above-described embodiment, a label without a mount is illustrated using a thermal head of a label printer. However, the present invention is not limited to this, and a seal labeler or a simple tape cutter is used as a seal on which fixed information is printed. For example, the label may be used for a label without a mount used in the above or a label without a mount having a perforation. Also, types and properties of adhesives / release agents for label without mount (coating characteristics such as solvent, emulsion, hot melt, and UV curing systems, chemical structures such as silicon and alkyl, weak viscosity, strong viscosity, etc. There is no restriction on the use), frozen viscosity, etc., and any known combination is possible.
[0021]
【The invention's effect】
As described above, according to the mountless label of the present invention, when used in an apparatus such as a label printer or a label applicator, the label mounting shaft does not adhere to the label mounting shaft and can be smoothly finished. It is possible to prevent the branch pipe from being unwound as waste, and to use the non-mounting label without waste until the last piece.
