Abstract
Abstract A hose assembly and method of making the same are provided, the hose assembly having fluid passages therein for respectively conveying a volatile liquid in one direction from the container, the assembly comprising a flexible inner hose having an outer peripheral surface and defining an inner one of the passages, a flexible outer hose having an inner peripheral surface and being disposed around the inner hose, the inner peripheral surface of the outer hose and the outer peripheral surface of the inner hose defining an outer one of the passages, a coupling fixed to an end portion of the outer hose, a tubular fitting fixed to an end portion of the inner hose, and a holding unit holding the fitting and the end portion of the inner hose substantially concentrically within the coupling and the outer hose to define a continuation of the outer passage, the holding unit comprising a spider-like member having a ring telescopically disposed on the fitting and a plurality of substantially straight arms radiating outwardly from the ring and being engageable with the coupling, the spider-like member comprising a one-piece extruded part.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
188 words
In a hose assembly having fluid passages therein for respectively conveying a volatile liquid in one direction to a container and returning vapors of said volatile liquid from said container, said assembly comprising a flexible inner hose having an outer peripheral surface and defining an inner one of said passages, a flexible outer hose having an inner peripheral surface and being disposed around said inner hose, said inner peripheral surface of said outer hose and said outer peripheral surface of said inner hose defining an outer one of said passages, a coupling fixed to an end portion of said outer hose, a tubular fitting fixed to an end portion of said inner hose, and holding means holding said fitting and said end portion of said inner hose substantially concentrically within said coupling and said outer hose to define a continuation of said outer passage, the improvement wherein said holding means comprises a spider-like member having a ring telescopically disposed on said fitting and a plurality of substantially straight arms radiating outwardly from said ring and being engageable with said coupling, said spider-like member comprising a one-piece extruded part.
Claim 2
Dependent Claim
188 words
In a hose assembly having fluid passages therein for respectively conveying a volatile liquid in one direction to a container and returning vapors of said volatile liquid from said container, said assembly comprising a flexible inner hose having an outer peripheral surface and defining an inner one of said passages, a flexible outer hose having an inner peripheral surface and being disposed around said inner hose, said inner peripheral surface of said outer hose and said outer peripheral surface of said inner hose defining an outer one of said passages, a coupling fixed to an end portion of said outer hose, a tubular fitting fixed to an end portion of said inner hose, and holding means holding said fitting and said end portion of said inner hose substantially concentrically within said coupling and said outer hose to define a continuation of said outer passage, the improvement wherein said holding means comprises a spider-like member having a ring telescopically disposed on said fitting and a plurality of substantially straight arms radiating outwardly from said ring and being engageable with said coupling, said spider-like member comprising a one-piece extruded part.
Claim 3
Dependent Claim
191 words
In a method of making a hose assembly having fluid passages therein for respectively conveying a volatile liquid in one direction to a container and returning vapors of said volatile liquid from said container, said assembly comprising a flexible inner hose having an outer peripheral surface and defining an inner one of said passages, a flexible outer hose having an inner peripheral surface and being disposed around said inner hose, said inner peripheral surface of said outer hose and said outer peripheral surface of said inner hose defining an outer one of said passages, a coupling fixed to an end portion of said outer hose, a tubular fitting fixed to an end portion of said inner hose, and holding means holding said fitting and said end portion of said inner hose substantially concentrically within said coupling and said outer hose to define a continuation of said outer passage, the improvement comprising the step of forming said holding means to comprise a one-piece extruded spider-like member having a ring telescopically disposed on said fitting and a plurality of substantially straight arms radiating outwardly from said ring and being engageable with said coupling.
