In the plastic casing of this Figure 15, with respect to base plate 15, by folding line 12,14 make the left and right sides sidewall 3 of left and right sides, 5 erect, under this state, with sidewall 3a before and after the inboard, 3a, 5a, 5a is to the folding line 11 of base plate 15,13 side bendings, make inboard before and after sidewall 3a engaging cut channel 3b and inboard before and after the engaging cut channel 5b of sidewall 5a slide up and down and engaged, therefore sidewall 3a before and after inboard can be connected with inboard front and back sidewall 5a, after sidewall 3a before and after the inboard and inboard front and back sidewall 5a are connected, sidewall 2 before and after its outside makes, 4 erect and assemble, and can assemble in the mode of not using lining cement.

In addition, in the plastic casing shown in the expansion drawing of Figure 15, under deployed condition as shown in figure 15, also can owing to antiseptic is housed, therefore can wholesomely use as the table trencher in the spot camping etc. in plastics inner, after cutting vegetables using etc. as table trencher, assemble and be casing, vegetables of cutting etc. can be accommodated in inside, thereby can under the good cold insulation state, carry.

In addition, under the situation that cold insulation is carried on one side on one side in that casing is put in medicine or clinical reagent etc., can in the part of handle 30,30 lock be installed in advance, making has only specific personnel can open casing, be used to open the password of this lock or dialing etc., need by read the two-dimensional bar code that is arranged on the casing for example the QR bar code learn.

In addition, plastic casing is configured to the double-layer structural with the plate formation of thermoplastic resin, and the thickness that is formed on inboard air layer is the hollow structure of 0.5mm-0.6mm.

In the casing of plastic hollow structure, can improve effect of heat insulation by the in-to-in air layer, thereby can prevent that the food equitemperature that is accommodated in box house from rising, and, by being put into refrigerator, plastic casing carries out precooling, cold air enters in the air layer, can improve the precooling effect of casing further.

And, plastic casing also can be the formed three-layer structure of plastic flagstone, in this case, can on the plastic flagstone in inboard and the outside, put into antiseptic, charged preventor, and can on the plastic flagstone of interlayer, utilize temperature sensitive paint or temperature indicating ink and form the variable color part.

For example, when temperature rises to more than 25 ℃, can appear the temperature sensitive paint of " needing refrigeration " or " please cooling off immediately " etc. or the literal of temperature indicating ink in one's mind, variable color by temperature sensitive paint or temperature indicating ink, can easily estimate the temperature of confirming casing and rise, thereby can supervise the user to note.

In addition,, in casing, be equipped with under the situation of medicine etc. even temperature sensitive paint or temperature indicating ink can be the material of irreversibility that cooling can not return to original color, can be by the temperature sensitive paint or the temperature indicating ink formation variable color part of this irreversibility.

And, also can adding on the whole or can absorb ultraviolet ray and painted ultraviolet color-changing agent during coating contact sunshine at the plastic flagstone of the interlayer of three-layer structure.

For this material, when casing contact light and temperature when rising, casing is colored, and can access shaded effect, thereby can prevent that the food equitemperature that box house is taken in from rising.

In addition, be under the situation of plastic double-layer structural or three-layer structure at casing, the opening portion of end face is closed to good.
