Abstract: A package assembly includes a base plate having multiple first connecting blocks each having a first wall and two first inserts respectively formed on two opposed sides of the first connecting block and two U-shaped connecting blocks oppositely formed on two opposed sides of the base plate, a top plate foldably connected to a side of the base plate and having multiple second connecting blocks, a cutout and a channel to accommodate the second connecting blocks when the top plate is folded relative to the base plate and two shoulder plates respectively and foldably formed on two opposed sides of the base plate to sandwiched the side having the top plate.

Abstract: A packing device made of thermo-formed plastic sheet includes a bottom plate having adjacent first recesses and each first recess has first flaps which are higher than a receiving plane of the first recess, and each first recess has a positioning portion in an inside thereof. A side plate being foldable along a folding line relative to the bottom plate has engaging portions which are engaged with the positioning portions. The side plate includes adjacent second recesses and each second recess has a plurality of second flaps which are higher than a receiving plane of the second recess. The side plate has receiving portions located opposite to the engaging portions. A top plate being foldable along a folding line relative to the side plate has protrusions which are engaged with the receiving portions when the top plate is folded the folding line toward the side plate. The top plate has third recesses and each of which has third flaps which are higher than a receiving plane of the third recess.
