Abstract: A display container with a bubble portion mounted on a base portion and adapted for easy access to products contained therein without destruction of the container. The base portion includes a flap and tab connected in seriatim at one extremity thereof, this construction being folded back beneath the remaining portion of the base and allowing the tab to protrude through the base in a position to support the bubble portion.

Abstract: A screw type anchor device for securement into masonry structures. A sharp crested helical thread, preferably with tapering crest diameter, is formed along the shank and helical protuberances forming guide means are spaced along the shank between adjacent convolutions of the helical thread. Notches are formed on the crests of the helical thread along the length of the shank to facilitate embedment of the crests in the walls of a performed bore in the masonry structure.

Abstract: A multifinger contact device is produced by a series of deforming stations which compress the fingers into die cavities decreasing the width of the fingers while severing the adjacent fingers from one another, by deforming the adjacent fingers first in one direction and then in the other to decrease the formation of burrs. A subsequent forming station may be utilized to confine the entire periphery of the finger so as to form opposing longitudinal edges on adjacent fingers into noncontacting curved surfaces.

Abstract: A self-drilling and blind setting rivet assembly for power tool application to workpiece means including a hollow rivet sleeve with an enlarged head at one end. A mandrel with a drill point at one end positioned through the bore of the sleeve so that the drill point on the mandrel is positioned adjacent the end of the sleeve opposite the head portion. The mandrel shank will have a weakened portion of reduced cross-sectional area with the inner periphery of the sleeve and outer periphery of the shank including cooperating torque transmitting surfaces on either side of the weakened portion of the shank to allow torque to be applied directly to the shank with the torque transmitting means serving to bridge the weakened portion of the shank to enable the drill point to drill a hole and yet allow the shank to fracture upon appropriate tensile force during the setting operation.
