• Features of hollow structure 100-42 include the ability to use across several vehicle platforms. The benefits include a single piece construction that replaces several assembled injection moldings in a pressurized system.
• Hollow structures 100 to 100-42 have been shown and described throughout this specification. It should be understood that while some of the features of the various hollow structures disclosed within this specification may apply to different end-use applications, the various features of a particular hollow structure disclosed within may be used alone, or in combination with any feature(s) of any other hollow structure(s) disclosed within, as would be recognized by one reasonably skilled in the art.
• Hollow structure 100 (collectively including hollow structures 100-1 to 100- 42 above) is preferably formed from plastic using a blow molding process. Hollow structure 100 is preferably sufficiently rigid to be self-supporting (i.e. maintain its molded shape under its own weight) upon installation and with use in the vehicle.
• An exemplary plastic material comprises a thermoplastic such as polypropylene. Other plastics may include other olefins such as polyethylene. Accordingly, plastics material suitable herein include those plastic resins suitable for blow-molding that exhibit a tensile or flexural modulus value above 150,000 psi (1050 MPa).
• a particular preferred material would be high density polyethylene (HDPE), with a tensile or flexural modulus of about 200,000 psi (1400 MPa).
• suitable plastics include polyethylene and/or polypropylene copolymers, poly(vinyl chloride), low density polyethylene (LDPE), ethylene-vinylacete copolymers (EVA), linear low density polyethylene, and polyethylene terephthalate (PET).
• Blow Molding Handbook Rosato & Rosato (Hanser 1989) for a complete list of those resins suitable for the blow molding operation herein.
• Blow molding may be accomplished by providing a molten parison, generally in the shape of a hollow tube, between two halves of an open split mold, then inflating the parison as to expand it against the surfaces of the closed mold via air pressure.
• the parison is formed by either extrusion or injection molding. Where the parison is extruded, typically it is inflated immediately thereafter. However, where the parison is injection molded, it may be cooled for storage, then reheated at a subsequent time thereafter before blowing.
• an extruded parison is open ended at the lower end thereof, as opposed to an injection molded parison which is generally close ended.
• the mold begins to close when the parison has reached an appropriate length.
• air may be injected through the interior of the open ended parison to prevent collapse of the parison and associated adhesion of its wall sections to one another.
• a portion of the mold ordinarily seals or welds the open end of an open ended parison closed so that air subsequently injected into the parison is trapped within the interior of the parison. The subsequent build up or increase in air pressure within the parison forces the parison to stretch and expand against the surfaces of the closed mold.
• Blow molding is the preferred method for providing hollow structures 100 to 100-42 given that blow molding can provide a plastic structure with an interior cavity formed within the confines of a unitary wall structure. In the case where the application is that of a fluid reservoir, a unitary wall structure is preferred over a non- unitary wall structure to reduce the potential for leakage from the reservoir.
• Examples of other plastic processes which can provide hollow structures 100 to 100-42 include rotational molding (also known as rotomolding and rotational casting) and gas-assisted injection molding.
• rotational molding also known as rotomolding and rotational casting
• gas-assisted injection molding blow molding of hollow structures 100 to 100-42 is preferred over rotational molding given the longer cycle times associated with rotational molding.
• blow molding of hollow structures 100 to 100-42 is preferred over gas-assisted injection molding as the interior cavity produced in gas-assisted injection molding has a significantly smaller volume capability than the interior cavities which may be produced with blow molding.
