Abstract
This invention relates to a lightweight plastic yarn carrier adapted to receive yarn wound thereon to form a yarn package. The yarn carrier is comprised of a hollow conical tube with a reinforced end portion at one end of the tube. The end is formed of an annular end wall extending radially in from the end of the tube and an annular flange extending inwardly toward the opposite end of the tube from the inner periphery of the end wall. The peripheral wall, end wall and annular flange collectively define an inside annular channel within the carrier. The reinforcement of the end portion is comprised of a plurality of circumferentially spaced apart ribs extending across the inside annular channel and at least one circumferential rim extending from the end wall and circumferentially around the inside annular channel to reinforce the end portion of the carrier. With this reinforcement arrangement, the end wall better resists impact on the end and further prevents the spread of damage that may be incurred.
