Paper cushioning structure

Abstract

One embodiment of a paper cushioning structure includes an elongated, hollow support member of U cross-section having two open ends; and an elongated brace member of inverted U cross-section having two open ends, the brace member comprising a packing space defined by a first slope at one end, two sides extending from both ends of the first slope respectively, and two first wing slopes each extending transversely from an end of the side distal the first slope; a second slope at the other end, two sides extending from both ends of the second slope respectively, and two second wing slopes each extending transversely from an end of the side distal the second slope; spaced flat first and second bottoms; and two sides. The brace member is securely disposed in the support member.

1 . A paper cushioning structure comprising:
 an elongated, hollow support member ( 1 ) of U cross-section having two open ends; and   an elongated brace member ( 2 ) of inverted U cross-section having two open ends, the brace member ( 2 ) comprising a packing space (V 1 ) defined by a first slope ( 221 ) at one end, two sides ( 226 ,  226 ′) extending from both ends of the first slope ( 221 ) respectively, and two first wing slopes ( 223 ,  223 ′) each extending transversely from an end of the side ( 226  or  226 ′) distal the first slope ( 221 ); a second slope ( 221 ′) at the other end, two sides ( 227 ,  227 ′) extending from both ends of the second slope ( 221 ′) respectively, and two second wing slopes ( 224 ,  224 ′) each extending transversely from an end of the side ( 227  or  227 ′) distal the second slope ( 221 ′);   spaced flat first and second bottoms ( 222 ,  222 ′); and two sides ( 225 ,  225 ′), wherein the brace member ( 2 ) is shaped to securely dispose in the support member ( 1 ).
