Abstract
A glass bottle is configured to improve the mechanics of liquid flow and prevent drip initiation. Additionally, the glass bottle eliminates dripping during pouring to enable drip free pouring. The dripping is prevented over a full range of pouring angles, which vary depending on the amount of liquid held in the glass bottle. A method of making the glass bottle and a method of enabling drip free pouring using the glass bottle are also disclosed.
Claims39
A method for enabling drip free pouring comprising:
- providing a glass bottle comprising a lip extending from an inner edge defining a substantially round bottle orifice to a pouring edge, wherein said lip forms a concentric and substantially flat ring around and perpendicular to the bottle orifice and a neck cone portion of the glass bottle extends from the pouring edge of the lip in a conical taper such that an outer diameter of the neck cone portion decreases along at least a portion of the neck cone portion as the neck portion extends from the lip, wherein a major conical angle defined by the conical taper of the neck cone portion ranges from about 30 degrees to about 60 degrees, and further wherein the pouring edge of the lip has an acute included angle ranging between about 60 degrees and about 75 degrees and comprises a radius of curvature of between about 0.25 mm and 2.0 mm;
- and wherein the glass bottle further comprises at least one of:
- (i) an interior surface of a neck configured to be sealed with a cylindrical plug style closure and (ii) a neck collar extending outward from an outer surface of the neck and having an upper edge located proximate to the pouring edge of the bottle, wherein a drip guard angle defined by the upper edge of the neck collar and the outer surface of the neck is less than 90 degrees.

A glass bottle comprising:
- a lip extending from an inner edge defining a substantially round bottle orifice to a pouring edge, wherein said lip forms a concentric and substantially flat ring around and perpendicular to the bottle orifice;
- and
- a neck cone portion of the glass bottle extending from the pouring edge of the lip in a conical taper such that an outer diameter of the neck cone portion decreases along at least a portion of the neck cone portion as the neck portion extends from the lip, wherein a major conical angle defined by the conical taper of the neck cone portion ranges from about 30 degrees to about 60 degrees, and further the pouring edge of the lip has an acute included angle ranging between about 60 degrees and about 75 degrees and comprises a radius of curvature of between about 0.25 mm and 2.0 mm;
- and
- wherein the glass bottle further comprises at least one of:
- (i) an interior surface of a neck configured to be sealed with a cylindrical plug style closure and (ii) a neck collar extending outward from an exterior surface of the neck cone portion and having an upper edge located proximate to the pouring edge of the bottle, wherein a drip guard angle defined by the upper edge of the neck collar and the exterior surface of the neck cone portion is less than 90 degrees.

A method for making a drip-free glass bottle comprising:
- forming a lip extending from an inner edge defining a substantially round bottle orifice to a pouring edge, wherein said lip forms a concentric and substantially flat ring around and perpendicular to the bottle orifice;
- and
- forming a neck cone portion of the glass bottle extending from the pouring edge of the lip in a conical taper such that an outer diameter of the neck cone portion decreases as the neck cone portion extends from the lip, wherein a major conical angle defining the conical taper of the neck cone portion ranges from about 30 degrees to about 60 degrees and further wherein the pouring edge of the lip has an acute included angle ranging between about 60 degrees and about 75 degrees and comprises a radius of curvature of between about 0.25 mm and 2.0 mm;
- and forming at least one of (i) an interior surface of a neck of the glass bottle, said interior surface configured to be sealed with a cylindrical plug style closure and (ii) a neck collar of the glass bottle, said neck collar extending outward from an exterior surface of the neck cone portion and having an upper edge located proximate to the pouring edge of the bottle, wherein a drip guard angle defined by the upper edge of the neck collar and the exterior surface of the neck cone portion is less than 90 degrees
