Abstract
Abstract A bottle of especial utility is disclosed. The bottle may be made of synthetic material as polyvinyl chloride. The bottle is formed by the rotation of a faired generating line made up from a straight linear segment and arcs of selected radii and centers about a central longitudinal axis. The linear segment of the generating line is parallel with the axis and the arcs are tangent at their points of juncture with each other and with the linear segment. The generating line thus rotated defines a form from which a mold is readily and inexpensively made to produce a bottle having adequate strength. The bottle may be used to contain, in particular, carbonated and like beverages or liquids. The bottom of the bottle is interiorly convex reentrant shape and has an exterior integral diametral reinforcing rib.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A molded plastic bottle comprising a base, a finish and a smooth following connecting side wall including a surface of revolution presenting substantially a cylindrically shaped body portion and a portion connecting said body portion and said finish, the bottle being characterized by the fact that throughout said connecting portion the generatrix, beginning at said finish, includes: a. a first arc of a circle whose concavity is directed radially outwardly; b. a second arc of a circle whose concavity is directed radially inwardly, said first and second arcs defining a neck of said bottle, said second arc having a radius which is more than twice the diameter of said body portion; and, c. a third arc of a circle whose concavity is directed radially inwardly, the radius of third arc being no greater than the radius of said second arc.
Claim 2
Dependent Claim
140 words
A molded plastic bottle comprising a base, a finish and a smooth following connecting side wall including a surface of revolution presenting substantially a cylindrically shaped body portion and a portion connecting said body portion and said finish, the bottle being characterized by the fact that throughout said connecting portion the generatrix, beginning at said finish, includes: a. a first arc of a circle whose concavity is directed radially outwardly; b. a second arc of a circle whose concavity is directed radially inwardly, said first and second arcs defining a neck of said bottle, said second arc having a radius which is more than twice the diameter of said body portion; and, c. a third arc of a circle whose concavity is directed radially inwardly, the radius of third arc being no greater than the radius of said second arc.
Claim 3
Dependent Claim
22 words
The bottle of claim 1 wherein the radius of said first arc is small compared to the radius of said second arc.
Claim 4
Dependent Claim
29 words
The bottle of claim 1 further characterized by the fact that the length of the connecting portion is less than one-half the length between said finish and said base.
Claim 5
Dependent Claim
21 words
The bottle of claim 1 wherein the radius of said second arc is equal to the radius of said third arc.
Claim 6
Dependent Claim
21 words
The bottle of claim 1 wherein the radius of said second arc is greater than the radius of said third arc.
Claim 7
Dependent Claim
17 words
The bottle of claim 1 where said third arc extends through an angle of at least 4*.
Claim 8
Dependent Claim
14 words
The bottle of claim 1 wherein said plastic bottle is formed of polyvinyl chloride.
