Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhered surface structure of a label suitable for adhering a relatively large label to a case, container, cabinet or the like of electronic equipment.

[0002]

2. Description of the Related Art Conventionally, labels such as specifications, notes, explanations, etc. and patterns are printed on the front surface, and an adhesive-coated label is printed on the back surface of electronic equipment cases, containers, cabinets, etc. It is well known to use by pasting. The label attached to the case in this way is 7
Usually, the size is about 0 mm × 70 mm or less, and if the size is up to that level, no particular problem occurs.

[0003]

However, 100 mm
When a relatively large label of × 100 mm is attached, as shown in FIGS. 4A and 4B, the label 10 provided with the adhesive layer 12 on the back surface side of the base material 11 and the adhered surface portion 50 such as a case. Air was easily trapped between the gaps, and bubbles K were apt to be generated, which often caused swelling that would impair the appearance and adhesion defects such as wrinkles.

Further, in this type of label 10, even if the label 10 can be attached without causing defective adhesion, as shown in FIG. Edge part 1 when rubbed with
There was also a problem that 0a was turned over and easily peeled off.

A first object of the present invention is to provide a structure for the adhered surface of a label, which is less likely to cause adhesion failure such as swelling and wrinkles that impair the appearance.

A second object of the present invention is to provide a structure for the adhered surface of the label which makes it difficult to peel off the edge of the attached label.

[0007]

In order to achieve the above first object, the structure of the surface to be adhered of the label according to the present invention has an entire surface to be adhered to which a label having an adhesive layer on the back surface is adhered. The plurality of air vent grooves are arranged in parallel and / or intersect with each other.

In this case, as a preferred embodiment, it is preferable that the portion of the surface to be adhered other than the air vent groove is roughened by subjecting it to embossing or the like.

The air vent grooves may be straight or curved, and a large number of grooves may be formed in an appropriate pattern such as a lattice pattern.

In order to achieve the above-mentioned second object, the structure of the surface to be adhered of the label according to the present invention is such that the label having an adhesive layer on the back surface is adhered to the outer periphery of the surface to be adhered. It is characterized in that an annular groove into which the outer peripheral edge of the label is dropped is formed.

[0011]

In the structure of the adhered surface portion of the label according to the present invention having the above-described structure, since the air vent groove is formed over the entire adhered surface, the back surface of the label is adhered to the adhered surface when the label is adhered. Since the air between the surface and the surface is removed to the outside through the groove, bubbles and the like are less likely to occur, and adhesion defects such as swelling and wrinkles are less likely to occur.

In addition to this, since the surface other than the above-mentioned air vent groove is roughened by subjecting it to a rough surface, the air between the label and the surface to be adhered is passed through the minute irregularities forming the rough surface. Is reliably released into the groove and is discharged to the outside through the groove, so that bubbles and the like are further less likely to occur.

Since the outer peripheral edge of the label is dropped into the annular groove formed on the outer peripheral surface of the surface to be adhered, the outer peripheral edge does not rise, so that the label can be easily flipped. It becomes difficult to peel off.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an adhered surface portion 20 of a case W of an electronic device to which an adhered surface portion structure of a label according to the present invention is applied.

In FIG. 1, the case W is made of synthetic resin, and the surface 20 to be adhered to which the label 10 is adhered has a substantially rectangular shape having a length and width of about 80 mm × 100 mm and rounded four corners. The label 10 provided with the adhesive layer 12 on the back surface of the base material 11 is adhered to the adhered surface 20 as in the conventional case.

Here, the annular groove 2 into which the outer peripheral edge portion 10a of the label 10 is dropped on the outer peripheral portion of the adhered surface 20.
2 is formed. The annular groove 22 has a width La of about 0.5 mm and a depth Ha of about 0.6 mm, and as shown in FIG. 2, the label 10 is properly placed on the adhered surface 20. The vertical and horizontal dimensions are set so that the outer edge 22a is located slightly (about 0.2 mm) outside the outer peripheral edge (dashed line) of the label 10 and the inner edge 22b is located inside the outer peripheral edge of the label 10. Outer edge 1
0 is bent downward so that its upper surface edge enters into the annular groove 22 as shown by the solid line in FIG.

On the surface 20 to be adhered, nine parallel vertical grooves 24 and seven parallel horizontal grooves 25 are formed in a grid pattern at regular intervals (about 10 mm).
The vertical groove 24 and the horizontal groove 25 have a width La of about 0.5 mm and a depth Ha of about 0.2 mm, and both ends thereof are joined to the annular groove 22.

Further, the annular groove 2 in the surface 20 to be adhered
As shown in FIG. 3, embossing (beading) is applied to the rough surface 26 except the vertical groove 24 and the horizontal groove 25.
Has been

Under the structure as described above, the adherend surface 2
Since the vertical groove 24 and the horizontal groove 25 for air bleeding are formed over the entire 0, the air between the back surface (adhesive layer 12) and the adhered surface 20 of the label 10 when the label 10 is attached is the groove 24, Since it is removed to the outside through 25, bubbles and the like are less likely to be formed, and adhesion defects such as swelling and wrinkles are less likely to occur.

In addition, the air vent groove 24,
Since the rough surface 26 is formed by subjecting the portions other than 25 to the rough surface 26, the air between the label 10 and the surface 20 to be adhered is surely passed through the minute uneven portions forming the rough surface 26. The air bubbles are escaped to the grooves 24 and 25 and are discharged to the outside through the grooves 24 and 25 and the annular groove 22, so that bubbles and the like are further less likely to occur.

Further, since the annular groove 22 is formed in the outer peripheral portion of the adhered surface 20, by dropping the outer peripheral edge portion 10a of the label 10 into it, the outer peripheral edge portion 10a does not rise. The label 10 does not easily turn over and is difficult to peel off.

Although the adhered surface 20 in the above example is a flat surface, the adhered surface may be curved to some extent, and even if there are gentle irregularities, the label 10 can be adhered without causing defective adhesion. Can be pasted.

Further, the air bleeding groove is not limited to a straight line, but may be a curved line such as a circular arc, and the extending direction thereof is not limited to the vertical and horizontal directions but may be an oblique direction.

[0024]

As is apparent from the above description, the structure of the adhered surface portion of the label according to the present invention has the air-releasing groove formed in the adhered surface, so that the back surface of the label and the adhered surface are adhered when the label is attached. Since the air between the surface and the surface is removed to the outside through the groove, bubbles and the like are less likely to occur, and adhesion defects such as swelling and wrinkles can be less likely to occur.

In addition to this, since the surface other than the above-mentioned air vent groove is roughened by subjecting it to a rough surface, a space between the label and the adhered surface is provided through a minute uneven portion forming the rough surface. The air is surely allowed to escape to the groove and is discharged to the outside through the groove, so that bubbles and the like can be further prevented.

On the other hand, by dropping the outer peripheral edge of the label into the annular groove formed on the outer peripheral portion of the surface to be adhered, the outer peripheral edge does not rise, so that the label cannot be easily flipped over, The effect that it becomes difficult to peel off is obtained.
