Abstract
Abstract A convertible assembly that is adapted to hold a folded flexible container capable of being unfolded to a relatively large volume container and to effectively serve as the neck of that container when the latter is extracted and unfolded, comprising a rigid tubular member having reduced diameter opposite end portions formed with threads for mounting screw thread caps, and an internal ring mounted within the tube whereby upon removal of the caps and extraction of the folded container the neck of the container may be inserted through one tube end and positively held in place on the tube by the internal ring and material may be introduced into and dispensed from the unfolded container through the other tube end.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A convertible assembly that is adapted to hold a folded flexible container and to effectively serve as the neck of said container when the latter is extracted and unfolded, comprising a rigid tubular member having opposite end portions formed with cap mounting means, closure caps removably mounted on said end portions, and an internal ring mounted within said tube, said tube being capable of enclosing a folded container having a reduced size neck at one end and which when unfolded can contain an appreciably larger volume of fluid material than said tube, and being so constructed and arranged that upon removal of said caps and extraction of the folded container the neck of the container may be inserted through one tube end and positively held in place on the tube by said internal ring, whereby material may be introduced into and dispensed from said container through the other tube end.
Claim 2
Dependent Claim

Claim 6
Dependent Claim
24 words
The convertible assembly defined in claim 4, wherein said cap at said one end of the tube holds said internal ring within the tube.
