Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
232 words
In a parenteral solution bag comprising at least one port tube protruding from part of the perimeter of the bag and hermetically enclosed by a bag-like protective closure, a diaphragm provided in the port tube sealing off the port tube from flow-off liquid within the bag through the port tube, and a tab peripherally heat sealed to a portion of said protective closure having an unsealed free end, the improvement which comprises in combination: a. the free end of the tab extending toward said bag, b. a V-shaped groove extending through said protective closure and into said tab, said tab and said closure being connected by a heat seal which extends along the periphery of said groove, and a pair of ribs on said closure, said ribs extending adjacent said groove, c. the apex of said V-shaped groove facing toward the junction of said port tube with said bag, d. said V-shaped groove being positioned over said port tube and extending transversely to the port tube, and e. the heat sealed portion of said tab being more rigid than the portion of said protective closure not sealed to said tab so that when the tab is peeled and turned backward towards the opposite side of said port tube, said heat sealed portion of said tab does not bend but instead said portion of said protective closure not sealed to said tube bends.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
44 words
The parenteral solution bag of claim 1 wherein there is on said tab a pair of longitudinal heat seal portions accompanied with ribs spaced apart from one another and depending parallel to the longitudinal axis of said port tube from adjacent said V-shaped groove.
Claim 4
Dependent Claim
83 words
The parenteral solution bag of claim 1 wherein said protective closure is a rectangular shaped envelope formed of plastic sheet heat sealed along the two longest sides and one of the shorter sides, the other short side is heat sealed to said bag with said port tube enclosed by said protective closure and said V-shaped groove faces inward toward said port tube and extends from the heat seal along one of said longest sides to the heat seal along the other longest side.
