摘要:
Processes are disclosed for producing plastic containers from thermoplastic sheets where the thermoplastic sheets are processed in parallel to form a low permeation plastic container. A plurality of thermoplastic sheets are progressively heated to a first temperature in a pre-conditioning stage. A group of the thermoplastic sheets are selected from the plurality of thermoplastic sheets and rapidly heated to a second temperature in a final heat stage. The group of thermoplastic sheets are then processed in a forming stage to form the low permeation plastic container.

An adapter provides for mounting an object on plastic. The adapter comprises a body coupled with at least two feet. The feet are weldable to the surface of the plastic while the plastic is in a molten state. The adapter also includes a coupling mechanism coupled with the body. The coupling mechanism is operable to couple the object with the adapter.

摘要:
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.
摘要:
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. The low permeation barrier layer is exposed at the pinchoff end. The connection further includes a first adhesive layer disposed between the continuous inner polymeric layer and the low permeation barrier layer, and a second adhesive layer disposed between the low permeation barrier layer and the outer polymeric layer. The connection further comprises a barrier bridge disposed on the pinchoff end to bridge the pinchoff gap. The barrier bridge has material compatible with low permeation barrier layer to connect the first and second barrier ends for continuity therebetween.
摘要:
A cutting tool [10] for use in forming circular and non-circular holes in a workpiece [16] includes a boring shaft [12] that is rotatable about an axis [15] and a boring head [14] that is secured to the boring shaft [12]. A cutting blade [46] extends beneath the bottom surface of the boring head [14] and is spaced apart from the axis [15]. A slug pin [58] extends from the bottom surface of the boring body to pierce and retain the slug after it has been cut to prevent it from falling into the workpiece [16].
