Abstract: This invention pertains to an upstanding container having a corrugated sidewall. Flutes in the medium of the corrugated sidewall follow preferably equal and opposite alternating lateral divergences from generally longitudinal upstanding axes. Preferred alternating divergences are waves having gradually changing angles of divergence from the respective upstanding axes. Thus, preferred medium is characterized by a pattern of wavy flutes. The pattern of wavy flutes provides improved strength and rigidity imparted by the horizontal components of the waves. Wavelength of the flutes is generally no greater than the height of the container. Wave amplitude is preferably between about 1/20th and about 1/80th of the circumference of the container. Spacing between flutes may be uniform from top to bottom of the container. In some embodiments, spacing between flutes is greater at or adjacent the top of the container than at or adjacent the bottom of the container.

Abstract: A device for causing a trolled bait to dive and thereafter to move horizontally from side to side in a rhythmic and pulsing fashion, comprising a thin generally non-flexible planar shape having a weight or a plurality of weights mounted thereon, the center of mass of the weight being positioned radially outward from the center of mass of the non-flexible planar shape and a fishing line affixing device attached at a point on the device, on a line extending from the center of mass of the planar shape through the apparent center of mass of the weights, the preferred position being at a point two thirds of the way from the center of mass of the planar shape to the center of mass of the weight, and a release device operative to cause the device cease its side to side motion upon retrieval of the trolled bait or upon the baits being struck by a fish.
