Abstract

The utility model relates to an indicator used for detecting whether desiccants stored in packing containers are effective. The utility model is characterized in that the middle of a sheet-shaped material with strong water absorbing property is coated with three geometrical picture-shaped outer frames. Three humidity color-changing agents with different proportions are respectively coated on the cavity bodies of three geometrical picture-shaped cavity bodies, so as to form three color-changing windows with different extents. The effective conditions of desiccants can be determined from the color change displayed on the color-changing windows, so as to remind users to change the desiccants timely.

Description

The effective indicator of drying agent

The utility model relates to the drying agent field in the packing container, belongs to specifically to detect after stored drying agent absorbs moisture content in the packing container, and can a kind of utensil that continue to use can be widely used in the moistureproof utensil of industries such as food, electronic devices and components.

The food that existing market is supplied especially electronic devices and components etc. all needs moistureproof, the city higher to coastal humidity more can take into account humidity resistance, generally in this type of packing container, deposit drying agent, but after drying agent is thrown in, time has been grown this drying agent and will lose effect, especially the area of high humidity or season, very fast drying agent will lose efficacy, whether and existing drying agent is deposited with paper or cloth bag, can't observe this drying agent lose efficacy, and the drying agent after the inefficacy continues to use, can't observe this drying agent whether lose efficacy, drying agent after the inefficacy continues to use, and then loses drying effect, and article will cause rotten or damage.

The utility model purpose provides a kind of and drying agent leaves in the packing container simultaneously, can discern the effective indicator of drying agent of the effective Cheng Du of this drying agent at any time.

For finishing the technical scheme that above-mentioned purpose is taked: will apply three geometric figure housings in the middle of the bibulous tablet, three geometric cavity A, cavity B, cavity C are the variable color window, and wherein three A, B, C variable color windows apply the humidity colour-changing agent of different proportion respectively.

The utility model solves and to come in packing container stored drying agent can't know whether effective shortcoming for a long time, especially because of continuing to use, the drying agent inefficacy cause damage to be overcome some accurate camera lenss and electron device, can remind the user in time to change, this indicator can apparently outside measure stored drying agent effective procedure, for operator provider makes.

The utility model embodiment is described in detail in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural drawing, wherein circular variable color window;

Fig. 2 is the structural drawing of the utility model triangle variable color window;

Fig. 3 is the structural drawing of the square variable color window of the utility model.

According to Fig. 1～shown in Figure 3, in the middle of bibulous tablet 1, apply three geometric figure housings, this bibulous tablet can be filter paper, fabric or bonded fabric, three geometric figures are respectively figure 2, figure 3, figure 4, three geometric figures 2,3,4 are respectively three cavity A, cavity B, cavity C, above-mentioned three cavity A, B, C applies the humidity colour-changing agent of different proportion respectively, thereby constitute three variable color windows in various degree, this humidity colour-changing agent is the reagent of cobalt chloride and so on, and the variable color window that above-mentioned three different geometric figure housings constitute can be a triangle, circular, square, Deng.

The utility model in use, can combine with desiccant bag, three variable color windows begin variable color after drying agent in use absorbs certain moisture content, because three cavity A, B, C apply the humidity colour-changing agent of different proportion respectively, wherein from small to large, be normal use, prompting changing, demonstration inefficacy by the variable color degree.During normal the use three variable color window A, B, C be shown as deep blue; During the prompting changing drying agent, variable color window C and B by deep blue progressively become pink; When variable color window A, B, C entirely by deep blue pulverize redness, illustrate that drying agent lost efficacy, can not play the effect of drying.

Claims

1, the effective indicator of a kind of drying agent, it is characterized in that applying three geometric figure housings in the middle of the bibulous tablet (1), be respectively figure (2), figure (3) and figure (4), three cavity A, B of three geometric figures (2)～(4), C are the variable color window, and wherein three variable color window A, B, C apply the humidity colour-changing agent of different proportion respectively.
