INTEGRATED PRESSURE PROOF FLUID CONTAINER WITH FLEXIBLE PIPE CONNECTORS
A fluid device that provides one or more features selected from being substantially tamper-resistant, substantially fluid-tight, and/or capable of providing stress relief to the various components used to form the fluid device. The fluid device accomplishes one or more of these features through the use of an injection material that is capable of substantially filling connection spaces in the fluid device using a low-pressure injection system. By using this injection material and a low-pressure injection system, the injection material may be injected into the connection spaces in the fluid device. Then, after the injection material has hardened, the injection material provides a mechanical barrier that provides the one or more benefits described.
1 . An improved fluid device comprising:
a housing;
a lid attached to the housing;
an inlet connector to the housing; and
an outlet connector from the housing;
wherein the fluid device includes at least one connection space between the housing and the lid, between the inlet connector and the housing, or between the outlet connector and the housing and wherein an injection material substantially fills at least one connection space between the housing and the lid, between the inlet connector and the housing, between the outlet connector and the housing, or a combination thereof.
2 . The fluid device of claim 1 , wherein the injection material is selected from thermoplastic elastomers, thermoplastic urethanes, styrene-ethylene-butylene-styrene elastomers, or a combination thereof.
3 . The fluid device of claim 1 , wherein at least one of the housing, the lid, the inlet connector and the outlet connector are constructed from a material selected from acrylonitrile-butadiene-styrene (ABS), polycarbonate, polycarbonate/ABS blend, a copolycarbonate-polyester, acrylic-styrene-acrylonitrile, acrylonitrile-(ethylene-polypropylene diamine modified)-styrene, phenylene ether resins, glass filled blends of polyphenylene oxide and polystyrene, blends of polyphenylene ether/polyamide, blends of polycarbonate/PET/PBT, polybutylene terephthalate and an impact modifier, polyamides, phenylene sulfide resins, polyvinyl chloride, high impact polystyrene, low/high density polyethylene, polypropylene and thermoplastic olefins, polyethylene and fiber composites, polypropylene and fiber composites, or combinations including at least one of these materials.
4 . An improved fluid device comprising:
a housing;
an inlet connector to the housing; and
an outlet connector from the housing;
wherein the fluid device includes at least one connection space between the inlet connector and the housing or between the outlet connector and the housing and wherein an injection material substantially fills at least one connection space between the inlet connector and the housing or between the outlet connector and the housing or both.
5 . The fluid device of claim 4 , wherein the injection material is selected from thermoplastic elastomers, thermoplastic urethanes, styrene-ethylene-butylene-styrene elastomers, or a combination thereof.
6 . The fluid device of claim 4 , wherein at least one of the housing, the lid, the inlet connector and the outlet connector are constructed from a material selected from acrylonitrile-butadiene-styrene (ABS), polycarbonate, polycarbonate/ABS blend, a copolycarbonate-polyester, acrylic-styrene-acrylonitrile, acrylonitrile-(ethylene-polypropylene diamine modified)-styrene, phenylene ether resins, glass filled blends of polyphenylene oxide and polystyrene, blends of polyphenylene ether/polyamide, blends of polycarbonate/PET/PBT, polybutylene terephthalate and an impact modifier, polyamides, phenylene sulfide resins, polyvinyl chloride, high impact polystyrene, low/high density polyethylene, polypropylene and thermoplastic olefins, polyethylene and fiber composites, polypropylene and fiber composites, or combinations including at least one of these materials.
7 . A method of making a fluid device comprising the steps of:
placing a fluid device into a low-pressure injection system wherein the fluid device comprises a housing, an inlet connector to the housing, and an outlet connector from the housing; wherein the fluid device includes at least one connection space between the inlet connector and the housing or between the outlet connector and the housing; and
injecting an injection material into at least one connection space between the inlet connector and the housing or between the outlet connector and the housing such that the injection material substantially fills at least one connection space between the inlet connector and the housing or between the outlet connector and the housing or both.
8 . The method of claim 1 , wherein the injection material is selected from thermoplastic elastomers, thermoplastic urethanes, styrene-ethylene-butylene-styrene elastomers, or a combination thereof.
9 . The method of claim 1 , wherein at least one of the housing, the lid, the inlet connector and the outlet connector are constructed from a material selected from acrylonitrile-butadiene-styrene (ABS), polycarbonate, polycarbonate/ABS blend, a copolycarbonate-polyester, acrylic-styrene-acrylonitrile, acrylonitrile-(ethylene-polypropylene diamine modified)-styrene, phenylene ether resins, glass filled blends of polyphenylene oxide and polystyrene, blends of polyphenylene ether/polyamide, blends of polycarbonate/PET/PBT, polybutylene terephthalate and an impact modifier, polyamides, phenylene sulfide resins, polyvinyl chloride, high impact polystyrene, low/high density polyethylene, polypropylene and thermoplastic olefins, polyethylene and fiber composites, polypropylene and fiber composites, or combinations including at least one of these materials.
10 . The method of claim 7 , wherein the fluid device further comprises a lid attached to the housing and wherein the fluid device includes at least one connection space between the housing and the lid and wherein the injection material is injected into at least one connection space between the housing and the lid such that the injection material substantially fills at least one connection space between the housing and the lid.
