Description
Technical field
The utility model relates to a kind of temperature-time indicating label, is applicable to goods in storage, monitoring in the transportation, induction and environment temperature and the exposure duration under this temperature thereof of record goods in storage, transportation.
Background technology
Biological products, agricultural byproducts and medicine all have certain requirement to storage and transportation environment, if the storage variation of ambient temperature reaches certain degree, can cause very big loss for businessman, serious entail dangers to people's life, as the biological species medicine, if surpassing uniform temperature, environment reaches certain hour, medicine will lose efficacy, can not treat or prevent disease, even have the opposite effect.Therefore, searching is a kind of simply can show, indicate goods to exist the method for environmental change necessary.This respect has been carried out the work of some abroad, and domestic also have some reports.From document and the patent of delivering, as United States Patent (USP) 6916116B2, diffusion liquid holding tank separates with spreading grooves, make diffusion liquid enter spreading grooves by extruding, cutting apart between two grooves, realize by bonding technology from holding tank, under situation about existing at diffusion liquid, bonding requires very high, the cohesive strength height, the extruding force that requires is big, use inconvenience, cohesive strength is low, and extraneous one has pressure, label just is activated, and requires high to storage, transportation and sale.For United States Patent (USP) 4601588, diffusion liquid is wrapped in the resin material particle, by the extruding broken resin, make diffusion liquid leak, spread, because inclusion particle consumption can not (grain amount be many more too much, the ratio of particle crushing is more little, total crushing amount increases little), the liquid that can spread is few, therefore, to thickness, the size requirements height of diffusion layer, the preparation difficulty is big.The shortcoming of Chinese patent 92100665.9,03805113.3 and 000814169.X is to have only above the regular hour to develop the color, do not reach the developing time point, be difficult to judge whether the residing environment of goods changes, Chinese patent 200580027449.6 and 200580026940.7 shortcoming are to judge the variation of environment temperature time by the depth of color, the judgement of human eye is limited, is difficult to judge the accurate variation of environment temperature time.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model provides a kind of temperature-time indicating label, by designing the convenient spacer that easily removes, as the cover plate that is easy to open, needle-like hair fine duct, frangible thin-walled glass kapillary, promptly solve diffusion liquid and extraneous isolating problem, solve again difficulty of processing big, to the demanding problem of storage, transportation and sales process.By design diffusion liquid storage pond, solve diffusion liquid consumption problem.Diffusion liquid is the gorgeous bright signal of diffusion continuously, can solve the continuous recording problem of human eye judgement finite sum.
The temperature-time indicating label that the utility model provides; label is provided with diffusion liquid storage pond and label base plate; the label base plate is provided with diffusion layer; diffusion layer is protected with protective seam, prevents to spread liquid to external diffusion or volatilization, and protective clear layer is provided with the panel of band view window outward; diffusion liquid storage is provided with diffusion liquid in the pond; behind the tag activation, diffusion liquid storage pond links to each other with the external world by the porous capillary line, and its activation is by external force diffusion liquid to be realized with extraneous the contact.Diffusion liquid is to have fixedly solidifying point and the temperature variant aqueous solution of liquid viscosity, alcohols such as terpinol, aldehydes such as trimethyl-acetaldehyde, phenols such as m-cresol, ester class such as methyl laurate, organic acid such as acrylic acid, ketone such as acetophenone, hydro carbons such as tetradecane or their potpourri to form.Contain the substance A that spreads the soluble pigment of liquid, dyestuff or can play chromogenic reaction in the diffusion liquid with solid matter B in the diffusion layer.The solid matter B of adhering in contained substance A and the diffusion layer in the diffusion liquid can be carried out complex reaction, acid-base reaction or redox reaction and be developed the color, and one of substance A or B are complexometric indicator, acid base indicator or redox indicator.
After its working mechanism is tag activation, diffusion liquid in the diffusion liquid storage pool is by spreading in the diffusion layer on the porous capillary alignment indicating label base plate, its rate of propagation is by the viscosity decision of environment temperature and diffusion liquid, the high diffusion of temperature is fast, the low diffusion of temperature is slow, the big diffusion of viscosity is slow, and the little diffusion of viscosity is fast.If in the diffusion liquid be pigment or dyestuff, diffusion liquid band it and is spread in diffusion layer and directly colour developing; If diffusion liquid contains chromogenic reaction thing A, then reactant A in the diffusion liquid and the reactant B in the diffusion layer are reacted and are developed the color in diffusion layer in diffusion process.Because the distance that diffusion liquid spreads in diffusion layer is by environment temperature and decision diffusion time, when environment temperature is lower than design temperature, diffusion liquid solidifies, its diffusion process in diffusion layer stops, when being higher than design temperature again, environment temperature (is higher than diffusion liquid solidifying point), diffusion liquid begins diffusion again in diffusion layer, so label demonstration and record is the cumulative function effect of environment temperature and exposure duration.
Because activation is needle-like hair fine duct band the porous capillary line and inserts diffusion liquid storage pond and make the porous capillary line and spread liquid and contact, or frangible capillary vessel fragmentation makes the porous capillary line contact with diffusion liquid, or take out and spread liquid storage pond overlayer and make the porous capillary line and spread liquid and contact, or frangible easily broken diffusion liquid wrappage fragmentation makes the porous capillary line contact with diffusion liquid, so the temperature-time indicating label preparation that the utility model provides is simple, easy to use, environment temperature and exposure duration can not disappear once record.Be elaborated to this use is novel below in conjunction with diagram and embodiment.
