Abstract: An industrial traffic curtain can be formed of a plurality of overlapping strips suspended contiguously to each other from a hanger fixed adjacent to a top margin of the opening. Each strip is of a flexible transparent material of substantially uniform longitudinal character having a lateral cross-section defined by an alternating series of thicker portions separated from each other by thinner portions, the thicker and thinner portions having approximately the same width, the thinner and thicker portions being united by narrower tapered regions of changing thickness. The traffic curtain thus formed exhibits a surprisingly lower electrostatic attraction between the strips so that the resistance to separation from each other as goods and transporting vehicles attempt to pass through the curtain is much lower than prior art curtains.

Abstract: A cap for dispensing material from a container defining an interior portion, including a housing capable of attachment to the container and including a translucent region, and defining an aperture, a first opening, and a second opening, and a spout member disposed through the aperture and defining a transfer compartment, having a first end and a second end and defining an inlet orifice at the first end and an outlet orifice at the second end, the spout member rotatably movable with respect to the housing between a first position where the inlet orifice is disposed to generally align with the first opening and communicate with the interior portion and the outlet orifice is disposed within and closed by the housing whereby material within the container may be transferred from the interior portion into the transfer compartment through the inlet orifice but material may not be dispensed from the container, and a second position where the inlet orifice is disposed within and closed by the housing and the outlet or
