Abstract: Low permeation fittings and low permeation plastic containers using same are constructed by molding an outer component into the wall of a plastic container while it is being formed. This causes the opening of a passageway in the outer component to be covered with wall forming material. The inner component is then inserted into the outer component through the wall forming material thereby trapping the wall material between the internal and external components. The barrier layer of the container wall is therefore continuous from the container to inside the fitting. A new fuel container, fuel neck fitting, and flange for mounting components on a fuel tank are disclosed.

Abstract: The present invention involves a low permeation pinchoff connection at a pinchoff region having a pinchoff end between first and second formed sheets of a fluid tank. The low permeation pinchoff connection comprises a continuous inner polymeric layer at a pinchoff region having a pinchoff end between the first and second formed sheets. The connection further comprises an outer polymeric layer in side-by-side relationship with the continuous inner polymeric layer. The outer polymeric layer tapers at the pinchoff region to first and second outer polymeric ends at the pinchoff end separating the first and second outer polymeric ends. The connection further comprises a low permeation barrier layer disposed between the continuous inner polymeric layer and the outer polymeric layer. The low permeation barrier layer tapers with the outer polymeric layer at the pinchoff region to first and second barrier ends separated at the pinchoff end to determine a pinchoff gap.
