Closure modules are coupled to and enclose ends of a multi-cell pressure vessel, especially a multi-cell pressure vessel having arcuate outer wall segments connected by internal web segments that define a plurality of cells in the pressure vessel. The closure modules each have an arcuate surface portion and at least one interfacing surface portion integrally connected at a marginal extent thereof with a marginal extent of the arcuate surface portion. The arcuate surface and interfacing surface portions define a closure module chamber and have peripheral edges. The arcuate surface portion of one of the closure modules abuts contiguously against an interfacing surface portion of an adjacent one of the closure modules. The closure modules are particularly useful for use with multi-cell tanks and vessel bodies, especially tanks and vessels suitable for storing liquid propane.

1. A set of closure modules for constructing therewith an end closure structure for a multi-cell pressure vessel which comprises a body portion comprising a plurality of arcuate outer wall segments connected by internal web segments so that the arcuate outer wall and internal web segments collectively define cells having opposite ends, said set of closure modules comprising:a first closure module comprising an arcuate surface portion and an interfacing surface portion, the interfacing surface portion having a marginal extent integrally connected with a marginal extent of said arcuate surface portion, said arcuate surface portion and said interfacing surface portion defining, collectively or in combination with at least one additional interfacing surface portion, a closure module chamber with a closure module opening, said closure module opening being defined at a periphery thereof by either free edges of said arcuate surface portion and said interfacing surface portion or free edges of said arcuate surface portion, said interfacing surface portion, and said at least one additional interfacing surface portion; and a second closure module adjacent the first closure module, the second closure module comprising an arcuate surface portion and an interfacing surface portion, the interfacing surface portion having a marginal extent integrally connected with a marginal extent of said arcuate surface portion, said arcuate surface portion and said interfacing surface portion defining, collectively or in combination with at least one additional interfacing surface portion, a closure module chamber with a closure module opening, said closure module opening being defined at a periphery thereof by either free edges of said arcuate surface portion and said interfacing surface portion or free edges of said arcuate surface portion, said interfacing surface portion, and said at least one additional interfacing surface portion, wherein said interfacing surface portion of said first closure module abuts contiguously against said interfacing surface portion of said second closure module.
