Abstract: An ice cream cone holder and drip collector device (10, 100, 200) includes a sleeve (12, 14) having an open upper end (16). A drip catcher (18, 28) is attached to the sleeve (12, 14) and includes an inner wall (20) that extends downwardly from the periphery of the open upper end (16) of the sleeve (12, 14). An outer wall (22) can be separated from the inner wall (20) by a spacer wall (24), the inner wall (20), outer wall (22), and spacer wall (24) forming the drip catcher (18). Because the drip catcher (18) attaches to the sleeve (12) at the open upper end (16) of the sleeve (12) and the drip catcher (18) provides no surface that is parallel to the vertical plane, a plurality of devices (10) can be intimately stacked one on top of the other and packaged in high density.
