[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a label attached to a product for display or the like.

[0002]

2. Description of the Related Art Conventionally, a label is attached to a curved surface of a cap or a barrel of a writing instrument or the like having a curved surface or a product having a curved surface for the purpose of describing a fixed price, precautionary statements, decoration, and the like. The label is formed by using a metal film such as aluminum or a resin film such as paper, vinyl chloride, polyester or the like as a base film, a printed portion on the front surface, and an adhesive on the back surface. As shown in FIG. 3, a commonly used sticking label has a printed portion provided on the surface of a base film 3 made of polyester or the like, and a coloring layer 4 made of pigment or aluminum vapor and a pressure-sensitive adhesive layer 5 provided on the back surface. Is formed to form a label layer 1 and a release film 2 is further provided to form a master roll for labels. As shown in FIG. 4, the label 7 で is cut out in a frame including a printing area, and is punched out at least while penetrating the label layer 1, the remaining material 8 of the label layer is peeled off, and the label 7 に is placed on the release film 2. It is wound up in an arranged state. The label 7 # is peeled off from the release film 2 and is manually adhered to the shaft surface of the writing instrument 11 or the like as shown in FIG. 2, but the release film 2 is bent as shown in FIG. 6 in the process of the automatic assembling machine. Then, the label 7 # is wound up, the end portion of the label 7 # is raised, and the label 7 # is mechanically taken out and attached.
The thickness is appropriately selected depending on the material of the base film,
For example, in the case of a polyester base film, the label layer 1 usually has a thickness of about 10 μ to 100 μ,
If it is 25 μm or less, the floating state is incomplete, and there is a problem in sticking by an automatic machine. In addition, when the label layer 1 is thick, there is a problem that the sticking force is applied to the restoring force of the label when applied to a curved surface having a large curvature and the end of the label is peeled off as shown in FIG. Therefore, usually, the selection of the adhesive material suitable for the material of the adherend, the thickness of the label layer, etc. are set.However, the curvature of the adherend surface is large, and there is a case where the material has to be set to a material having poor adhesion. There are many problems that do not meet the conditions that require application by an automatic machine. In addition, there is a problem that even when the adhesive is temporarily adhered, it is easily peeled off under a high temperature and high humidity condition.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to realize that even if an adherend has a large curvature and adherence is poor, the adhered portion does not peel off and can be adhered by an automatic machine. Aim.

[0004]

Means for Solving the Problems The sticking label of the present invention devised to solve the above-mentioned problem has a printed portion on the front surface, an adhesive applied to the back surface, and a curved surface of the adherend. A notch is formed in a direction substantially perpendicular to a curved surface to be attached to a required portion of the label to offset the restoring force of the label against the adhesive force to prevent peeling.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. As shown in FIG. 3, the label 7 to be adhered according to the present invention has a printed portion 6 provided on the surface of a base film 3 made of polyester or the like, and a colored layer 4 and an adhesive layer 5 formed by vapor deposition of aluminum on the back surface. 1 is configured. The thickness of the label layer 1 is usually set in the range of 25 μ to 70 μ. Further, a release film layer 2 is provided on the pressure-sensitive adhesive layer 5 to form a master roll. As shown in FIG. 4, the label 7 is a frame including a printing area, is cut out at least while penetrating the label layer 1, and is provided with a cutout window 9 while leaving the label 7 on the release film layer 2. The uncut remaining material 8 is peeled and removed,
Labels 7 are arranged on the release film layer 2 as shown in FIG. The process up to this stage is the same as the conventional process.

By the way, at the same time when the label 7 is cut out, or at the next step, a cut 10
Is formed. A required number of cuts 10 are provided in a direction substantially perpendicular to the bending direction of the label 7 attached along the curved surface of the adherend, and are formed near both ends of the frame taking into account the appearance and labor. It is desirable. Also, cut 10
Is formed to an appropriate depth, but is desirably formed to a depth substantially penetrating the label layer 1. Also, the slit 10 may open a window in a slit shape.

When the labels 7 are to be stuck by an automatic machine, the labels 7 are wound in a state in which the release film layer 2 is bent as shown in FIG. Adhere to the adherend. At that time, since the release film layer 2 is peeled off in a direction perpendicular to the cut 10 of the label, it has the same rigidity as the conventional label 7 'having no cut and can be raised without any problem.

By the way, it is conceivable that the label is formed in a chamfered shape in which the width becomes narrower toward both ends. In this case, the rigidity of both ends is weakened in the bending direction of the bonding, but at the same time, the adhesive portion is formed. , The adhesive strength against the restoring force against the bending of the label cannot be obtained, and the peeling cannot be solved.

[0009]

As described above, the label of the present invention is shown in FIG.
Is attached to the axis of the writing instrument 11 as shown in FIG.
By forming 0, the restoring force of the label with respect to the adhesive force can be set weak, and peeling is prevented.

[0010]

The structure and operation of the present invention are as described above, and even if the adherend is made of a material having a large curvature of the adherend surface and poor adhesion, peeling is prevented. In addition, an effect of facilitating sticking by an automatic machine can be expected.
