Abstract
Abstract A gum collecting bag having front and rear panels, end overfolded, and Z-shaped side gussets connecting the panels. Extended side seam fins terminating beyond the periphery of the panels permit the bag to be readily affixed to gum trees and to assume the proper shape. A coating of a material which does not contaminate a gum melt, such as a polyamide resin or cellulose acetate, may be applied to the bag to enhance its capacity to withstand weathering during collection. The bag may have a reinforcement fold extending along the top of the longer panel and integral gussets and fins thereof.
