Shielding layer 230 is laminated in the surface of articulamentum 271.In the illustrated embodiment, shielding layer 273 is by lighttight It is prepared by ink printing.Certainly, in other embodiments, shielding layer 273 can also be laminated in the surface of articulamentum 271 impermeable Luminescent material, such as aluminium foil etc., as long as can play a part of shutting out the light.
It should be strongly noted that in use, covering 270 also acts as the effect of activation members, by pullling covering 270, give substrate layer 230 1 upward active forces, time passage instruction device 200 can be started.
Above-mentioned time passage instruction device 200 is upward to substrate layer 230 1 in use, by pullling covering 270 Active force, the second bonding part 244 is separated with reference section 223, form gap, so as to start time passage instruction device 200, edge Impression 290 and turn down covering 270, covering 270 is covered in the surface of substrate layer 230 after turning down, cover instruction unit 221；When When needing to observe the color of instruction unit 221, it is only necessary to raise covering 270.
Referring to Fig. 7, the structure of the time passage instruction device 300 of another embodiment and time passage instruction device 100 structure is roughly the same, and its difference is：Covering 370 is laminated in the surface of substrate layer 330, the part of covering 370 and base Material layer 330 is affixed, so as to which covering 370 can open predetermined angular with respect to substrate layer 330.
Covering 370 includes articulamentum 371 and is formed at the shielding layer 373 on the surface of articulamentum 371.Articulamentum 371 Material is selected from least one of paper, PET film, PVC film and BOPP film.Certainly, in other embodiments, articulamentum 371 Material is not limited to the above-mentioned species enumerated, as long as articulamentum 371 can play a part of carrying shielding layer 373.
Shielding layer 373 is laminated in the surface of articulamentum 371 and finger is completely covered in the projection of marker 320 in shielding layer 373 Show portion 321.In the illustrated embodiment, shielding layer 373 is printed by lighttight ink and prepared.Certainly, in other embodiment party In formula, shielding layer 373 can also be the light-proof material for being laminated in the surface of articulamentum 371, such as aluminium foil or thermoprint anodized aluminium etc., As long as it can play a part of shutting out the light.
Please refer to Fig. 8, Fig. 9, Figure 10, Figure 11 and Figure 12, in the illustrated embodiment, covering 370 is close to be opened One end of moving part 380 is bonded by tack coat 390 and activation members 380.In one of the embodiments, tack coat 390 passes through pressure It is prepared by quick glue.
Above-mentioned time passage instruction device 300 is upward to substrate layer 330 1 in use, by pullling activation members 380 Active force, the second bonding part 344 is separated with reference section 323, form gap, so as to start time passage instruction device 300；Just In the case of often, shielding layer 373 covers instruction unit 321, plays a part of shutting out the light, when the color for needing observation instruction unit 321 When, articulamentum 371 is raised, articulamentum 371 is opened certain angle with substrate layer 330.
Refer to Figure 13, the knot of the time passage instruction device 400 and time passage instruction device 300 of another embodiment Structure is roughly the same, and its difference is：The material of the covering 470 of time passage instruction device 400 is opaque material, covering 470 be single layer structure.
In one of the embodiments, the material of covering 470 is the polyethylene that surface recombination has aluminium foil, so as to individually make It can be played a part of covering instruction unit 421 with covering 470.
Above-mentioned time passage instruction device 400 is upward to substrate layer 430 1 in use, by pullling activation members 480 Active force, the second bonding part 444 is separated with reference section 423, form gap, so as to start time passage instruction device 400；Just Often in the case of, shielding layer covering 470 cover instruction unit 421, play a part of shutting out the light, when need observe instruction unit 421 Color when, raise covering 470, covering 470 and substrate layer 430 is opened certain angle.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
