Patent ID: 8163370

Claim:
A buffer device providing reliably buffer effect for mounting to an edge portion of an object to be protectively packaged, comprising: a channel-shaped buffer member having: two facing inner sidewalls; two opposite outer sidewalls being respectively provided with at least one first curved buffer section extended in a lengthwise direction of the channel-shaped buffer member; an inner bottom wall connected at two opposite longitudinal edges to lower edges of the two inner sidewalls, so that an elongated channel is formed between the inner bottom wall and the two inner sidewalls for receiving the edge portion of the object to be protectively packaged; two outer top walls connected at respective inner longitudinal edge to upper edges of the two inner sidewalls and at respective outer longitudinal edge to upper edges of the two outer sidewalls; and an outer bottom wall connected at two opposite longitudinal edges to lower edges of the two outer sidewalls; and the two inner sidewalls, the two outer sidewalls, the inner bottom wall, the two outer top walls and the outer bottom wall together enclosing and defining a third buffer space therein; and at least one first reinforcing tubular member being received in the third buffer space; the first reinforcing tubular member enclosing a first buffer space therein and including at least one normal-direction supporting wall extended between and pressed against the inner bottom wall and the outer bottom wall of the channel-shaped buffer member; and the normal-direction supporting wall being provided with at least one second curved buffer section extended in a lengthwise direction of the first reinforcing tubular member.
