这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:
- X3 V- V0 |4 [8 bA stuffed toy or beanbag constructed of pliable! K1 N' v% p+ f
material having seams (including, but not limited to, seams that
+ |7 R/ p7 E* c. {are stitched, glued, heat sealed, or ultrasonic welded) shall$ V4 l, Q3 w5 X6 a
have the seams subjected to a separate tension test in any

Table 5 according to the age group for which the toy is

由此可见,第二种要求是必要的
