Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A METHOD OF DISTENDING A BLANK FORMED OF SUPERIMPOSED SHEETS HAVING SELECTED PORTIONS OF THEIR ADJACENT SURFACES JOINED TOGETHER TO DEFINE BETWEEN SAID SHEETS A FORMATION OF INTERNALLY UNJOINED AREAS CORRESPONDING TO A DESIRED CONFIGURATION WITH SAID AREAS COMPRISING A FIRST UNJOINED AREA AND A SECOND UNJOINED AREA, SAID METHOD COMPRISING: (A) POSITIONING THE BLANK ON A FIRST RESTRAINING MEANS, (B) APPLYING DISTENDING FLUID PRESSURE INTO SAID FIRST UNJOINED AREA A DISTEND SAID FIRST UNJOINED AREA INTO PRESSURE-TIGHT RELATIONSHIP WITH A SECOND RESTRAINING MEANS, (C) APPLYING HOLDING PRESSURE INTO THE VOLUME BETWEEN SAID BLANK AND SAID SECOND RESTRAINING MEANS, AND (D) APPLYING DISTENDING FLUID PRESSURE INTO SAID SECOND UNJOINED AREA, TO DISTEND SAID SECOND UNJOINED AREA, DISTENSION BEING GREATER ON THE SIDE ADJACENT SAID SECOND RESTRAINING MEANS THAN ON THE SIDE OF SAID BLANK ADJACENT SAID FIRST RESTRAINING MEANS.

Claim 3
Dependent Claim
159 words
A BLANK FOR PRODUCING AN ARTICLE HAVING A DESIRED SYSTEM OF INTERNAL TUBULAR HOLLOWS, COMPRISING: (A) A FIRST SHEET AND A SECOND SHEET, SAID SHEETS BEING IN SUPERIMPOSED RELATIONSHIP, (B) A FIRST CONTINUOUS PATTERN OF STOP-WELD MATERIAL DISPOSED ON AT LEAST ONE OF SAID SHEETS AND IN THE CONFIGURATION OF SAID DESIRED SYSTEM OF INTERNAL TUBULAR HOLLOWS, (C) A SECOND CONTINUOUS PATTERN OF STOP-WELD MATERIAL DISPOSED ON AT LEAST ONE OF SAID SHEETS AND SUBSTANTIALLY SURROUNDING SAID FIRST PATTERN, (D) SAID FIRST AND SECOND SHEETS BEING SECURED TOGETHER IN SUBSTANTIALLY ALL THE PORTIONS OF SAID SHEETS NOT OCCUPIED BY STOP-WELD, (E) SAID FIRST AND SECOND PATTERNS BEING JOINED BY A PORTION OF STOP-WELD MATERIAL, AT LEAST A PART OF WHICH JOINING PORTION HAS A SECTION OF RESTRICTED CROSS SECTIONAL AREA TO ALLOW DISTENSION OF SAID SECOND PATTERN WHILE NOT PERMITTING EXPANSION OF SAID FIRST PATTERN UNTIL A PRESSURE GREATER THAN THAT REQUIRED TO DISTEND SAID SECOND PORTION IS REACHED.
