Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
A kind of self-heating plastic packing box as shown in Figure 1, Figure 2 and shown in Fig. 3, including inner box 20 and outer box 10, inner box 20
With outer box 10 with plastic uptake technological forming in the prior art.Inner box 20 is installed in outer box 10, and the outer wall of inner box 20 with
The inner wall interval of outer box 10 forms fever chamber, the top end opening for the chamber that generates heat.It is corresponding, extend outwardly in the top outer wall of inner box 20
Mouth-sealed portion is formed, which can be used for closing opening when inner box 20 is mounted on the inside of outer box 10.In addition, inner box 20 is outer
Wall, which is surrounded by, to be enclosed equipped with heating bag 30, and the heating bag 30 is affixed with inner box 20 in a manner of bonding.The side wall of inner box 20 is equipped with
Through-hole 21, through-hole 21 are penetrated through by the bottom face of inner box 20 to the top end face of inner box 20.The bottom end two sides inner wall of outer box 10 inwardly prolongs
Stretch the stage portion 12 to be formed and be used to support 20 bottom side edge edge of inner box, the bottom wall interval setting of stage portion 12 and outer box 10.
When on the basis of the said structure, using the self-heating plastic packing box of the utility model, inner box 20 can be mounted on
In outer box 10, the bottom end of inner box 20 can be supported by the stage portion 12 inside outer box 10, and the specific stage portion 12 can be by existing
Material (such as blob of viscose) in technology with certain degree of hardness is made, and the inner wall of outer box 10 is fixed in the way of bonding,
Inner box 20 is supported, reduces and the sagging situation of inner box 20 occurs.Certainly, stage portion 12 uses harder plastic shaping outside
