Ventilative gap, so that extraneous gas enters the inside of host body 140 by gap, the time is through instruction device 100 quilt
Activation, air is reacted with the indication composition being attached on adsorbate, so that the color of marker is changed, activation members are
The convenient handgrip gripping stretching out from the edge of substrate layer, handgrip is bent and free end that make described handgrip inserts seam
Gap, during use, after handgrip is bent, makes in the free end inserted into gap of handgrip so that gap is able to maintain that the state opened, keeps away
Exempt from substrate layer to fit together with basal layer, meanwhile, in the free end inserted into gap of handgrip, make gap have certain height,
Stability when instruction device uses for the time can be increased；After the color change cycle of marker 130 opens packaging with product
Shelf-life consistent when, people can intuitively be concluded that color show when marker close to initiateing face by comparing
During color, show that product is very fresh, can be safe to use, when the color that marker shows and intermediate colors are close, show product
Place a period of time, do not go bad, should use as early as possible, when the color that marker shows and terminal colour are close, show product
Rotten, should not be continuing with.Time is prepared by absorption through the marker of instruction device, and technique is relatively easy.
Need it is further noted that the variable color of marker 130 can be adjusted by the concentration adjusting indicating liquid composition
Cycle, certainly, by adjusting the thickness of marker 130 and the aperture of adsorbate micropore, such that it is able to control absorption in adsorbate
The total amount of interior indication composition.By transferring in the cross-sectional width of air cleft gap, can be started through instruction device 100 with regulating time
When the size in gap that formed, thus controlling air to enter internal speed, and then control color change cycle.
Refer to Fig. 7, time of an embodiment through instruction device 300 structure with the time through instruction device 100
Structure roughly the same, the time includes basal layer 310, substrate layer 320, marker 330, dielectric layer through instruction device 300
350th, protective layer 370, adhesive layer 380, peel ply 385 and activation members 390, its difference is, the time is through instruction device 300 not
Including comparing layer, other structures are identical through the structure of instruction device 100 with the time.
Time can coordinate single colorimetric card to use through instruction device 300, or printing ratio in the description of product
Colour atla.
Each technical characteristic of embodiment described above can arbitrarily be combined, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic applied in example is all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope of this specification record.
Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, some deformation can also be made and improve, these broadly fall into
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
