Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は腕時計用装飾カバーガラスに関するも
のである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a decorative cover glass for a wristwatch.

[Prior art]

従来より腕時計用カバーガラスに印刷、蒸着等
により装飾を施すことは行なわれている。しか
し、その装飾は単純なものが多く、立体感あるガ
ラスの装飾はあまり例がない。 BACKGROUND OF THE INVENTION Conventionally, cover glasses for wristwatches have been decorated by printing, vapor deposition, etc. However, most of the decorations are simple, and there are few examples of three-dimensional glass decorations.

[Purpose of invention]

本考案は、ガラスの表面、裏面の両方に、印刷
蒸着を施し、立体感のある装飾カバーガラスを得
ようとするものである。 The present invention attempts to obtain a decorative cover glass with a three-dimensional effect by performing printing vapor deposition on both the front and back surfaces of the glass.

[Structure of the idea]

る。 A metal layer is provided on a part of the back surface of the cover glass by vapor deposition, printing, etc. Furthermore, letters, abbreviations, marks, etc. are printed in two colors overlappingly on a part of the surface of the cover glass corresponding to the part where the metal layer is provided. When the cover glass made in this way is viewed from the top, the metal surface acts as a mirror, and the colors printed on the bottom of the top surface cannot be seen from above, but are reflected on the vapor-deposited surface. appear. Therefore, the printed portion appears three-dimensional.

以下、実施例に従がつて本考案を詳細に説明す

燥して完全硬化させた。 A cover glass was molded, and Cr was vapor-deposited on the back side of the glass. Seiko Advance 1690 was printed as a resist ink on the outer periphery, and
Allow to dry and harden. This glass was immersed in aqua regia to remove Cr from the areas where the resist was not attached. Through the above steps, a cover glass 1 with Cr2 vapor-deposited on the outer periphery and back printing 3 was completed. First, print pattern 4 with white ink on the surface of the part where Cr2 is attached on the back side of this glass, and then print it at 150°C.
Pre-dried for minutes. Furthermore, black printing 5 was applied in the same pattern on the white ink 4, and the ink was dried at 150° C. for 30 minutes to completely cure.

The Cr vapor deposited layer 2 reflects light like a mirror. When the cover glass 1 is viewed from above, the black print 5 is visible, and the white print 4 underneath is not directly visible. but,
When viewed from a position slightly tilted from directly above the cover glass 1, the white print 4 appears to be reflected by the Cr vapor deposition layer 2.
Therefore, the reflected images of the black print 5 of the second print layer and the white print 4 of the first print layer appear to be slightly shifted, resulting in a very three-dimensional appearance. Further, metal layers other than those described in this embodiment can be formed on the back surface of the glass, and various color combinations can be obtained by changing the colors printed on the glass surface. In addition to patterns, letters, abbreviations, marks, etc. can also be printed on the surface.

〔効果〕以上実施例に述べたように本考案によれば、非
常に立体感がある装飾的な腕時計用カバーガラス
を得ることができる。[Effects] As described in the embodiments above, according to the present invention, it is possible to obtain a decorative cover glass for a wristwatch that has a very three-dimensional effect.
