FIELD OF THE INVENTION
The present invention relates generally to a rigid and self-adhesive printed matter applicable to the surface of an object, and more particularly to a method for applying the rigid and self-adhesive printed matter to the curved surface of an object.
BACKGROUND OF THE INVENTION
As illustrated in
FIG. 3
, a label
40
is attached to the curved surface of an object
30
. The label
40
is provided with a soft layer
41
to facilitate the attaching of the label
40
to the curved surface of the object
30
. In light of the slight elasticity of the soft layer
41
, the label
40
is apt to become detached gradually from the curved surface of the object
30
.
In order to prolong the longevity of the label
40
, the label
40
may be provided with a rigid layer. Before applying the label
40
to the curved surface of the object, the rigid layer of the label
40
must be provided with a surface that is contoured to fit the curved surface of the object. Such a prior art method for applying the rigid and self-adhesive label to the curved surface of an object is inefficient at best. In addition, the label cannot be reused, once it is applied to the surface of the object. A more efficient method was devised such that the label is made of a plastic material by injection molding. However, the label is subjected to a high temperature of 180 degrees Celsius during the process. As a result, the label is apt to be damaged by heat or even become scorched.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a method for applying a rigid and self-adhesive printed matter to the curved surface of an object. The method of the present invention overcomes the deficiencies of the prior art methods described above.
The method of the present invention involves a first step in which the rigid and self-adhesive printed matter is coated with epoxy resin. Such a coated printed matter is baked at a predetermined temperature and is then contoured by a molding device so as to fit the curved surface of an object to which the rigid and self-adhesive printed matter is to be attached. The contoured printed matter is cooled before the printed matter is attached to the curved surface of the object by the self-adhesive surface thereof.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
