Abstract
A container system for pressurized fluids that includes a plurality of generally ellipsoidal chambers connected by a tubular core. The tubular core is formed along its length with a plurality of apertures each of which is positioned within one of the chambers. The apertures are of comparatively small size so as to be able to control the rate of evacuation of pressurized fluid should a chamber be ruptured.

A method of making a container system for storing pressurized fluids that includes the steps of:
- providing a plurality of form-retaining generally ellipsoid chambers having open ends;
- positioning said chambers in longitudinal alignment;
- providing a tubular core;
- forming fluid evacuation rate controlling apertures at longitudinally spaced points along the length of the tubular core;
- extending the tubular core through the open ends of the chambers with one of the apertures disposed within the interior of each chamber;
- and
- sealingly securing the tubular core within the ends of the chambers.
A method of making a container system for storing pressurized fluids that includes the steps of:
- molding a plurality for form-retaining synthetic plastic shells having a generally ellipsoidal configuration;
- forming a hole in the front and rear ends of the shells;
- aligning the shells in coaxial relationship;
- providing a tubular core of synthetic plastic material;
- making fluid evacuation rate controlling apertures at longitudinally spaced points along the length of tubular core;
- inserting a length of such tubular core within the holes of the shells, with one of said apertures disposed within the interior of each shell;
- wrapping the exterior surfaces of the shells and the tubular core with reinforcing fibers;
- and
- coating the exterior of the filament wrapped shells and tubular core with a protective coating.
Apparatus for making an assembly of generally ellipsoidal open-ended shells and a length of tubular core material, such apparatus comprising:
- a frame;
- a loader bin on the frame holding a plurality of arrays of the shells in horizontal and vertical alignment;
- a horizontal shell transfer tray on the frame below the loader bin in vertical alignment with the array of shells for vertical movement between a raised shell loading position and a lower shell ejection position;
- a tubular core supply source on the frame to one side of the loader bin;
- power-operated means on the frame to incrementally advance a length of tubular core material below the loader bin through the open-ends of the shells with a retention fit;
- a hole puncher on the frame to form apertures in said tubular core length on centers corresponding to the approximate centers of the spacing of the shell arrays;
- cutters on the frame to cut of said length of tubular core on either side of the shell loader tray;
- support means on the frame to support the shell transfer tray for vertical movement between its raised shell loading position and its lower shell ejection position;
- and
- an ejector on the frame to force the assembly of shells and tubular core out of the shell loader tray when said tray is disposed in its lower shell ejection position.
