Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
79 words
Stackable plastic bottles comprising a base wall, a side wall and a neck wall provided with an orifice, characterised in that the base wall and the neck wall each possess a central zone which, by virtue of a shoulder, projects relative to the peripheral zones of these walls, the location where each shoulder joins its respective peripheral zone defines a section, and said sections defined between said shoulders and said respective peripheral zones are substantially identical to one another.
Claim 2
Dependent Claim
79 words
Stackable plastic bottles comprising a base wall, a side wall and a neck wall provided with an orifice, characterised in that the base wall and the neck wall each possess a central zone which, by virtue of a shoulder, projects relative to the peripheral zones of these walls, the location where each shoulder joins its respective peripheral zone defines a section, and said sections defined between said shoulders and said respective peripheral zones are substantially identical to one another.
Claim 3
Dependent Claim
52 words

Claim 13
Dependent Claim
40 words
Bottles according to claim 1, characterised in that the surface area, projected onto a horizontal plane when the bottle is in the normal vertical position, of the base peripheral zone is less than twice that of the base central zone.
Claim 14
Dependent Claim
22 words
Bottles according to claim 1, characterised in that the overall height of the bottle is less than twice the largest transverse dimension.
Claim 15
Dependent Claim
21 words
