Free flowing bottle

Abstract

A glass bottle with improved pouring characteristics. In some embodiments the bottle can hold pressurized liquid. The bottle includes a neck with a non-circular cross section. The cross sectional shape of the neck is adapted and configured to provide less turbulence in the liquid being poured out of the bottle, and further to assist in separating the in flow of single phase liquid from the turbulent mixed flow of two phase, gas-liquid substances.

1 . A container, comprising:
 a glass bottle defining an interior for holding a quantity of a pourable substance consumable by humans, said bottle including:   a lip defining a cylindrical bore for pouring the substance out of said bottle, the bore being cylindrical about a centerline;   a body with a generally cylindrical base, the base being cylindrical about the centerline; said body including a portion of the interior, the interior having a plane of symmetry passing through the centerline;   a shoulder integral with said body and opposite of said base, said shoulder having two ends with one end blending into said body, said shoulder including an external molded recess for receiving the fingertip of a user, the recess being centered in the plane of symmetry; and   a neck having two ends with a narrow end integrally connecting to said lip and the other wider end integrally connecting to the other end of said shoulder, said neck defining a non-circular internal flow channel, the flow channel having an internal width in the plane of symmetry that is wider than the internal width orthogonal to the plane of symmetry.   
     
     
         2 . The container of  claim 1  wherein the internal flow channel of the neck has a first internal surface conically shaped at a first taper angle relative to the centerline, the first internal surface merging smoothly with a second internal surface conically shaped at a second taper angle relative to the centerline, the first angle being greater than the second angle. 
     
     
         3 . The container of  claim 3  wherein the first angle is about twice the second angle. 
     
     
         4 . The container of  claim 2  wherein the first angle is more than about ten degrees and less than about twelve degrees. 
     
     
         5 . The container of  claim 2  wherein the first internal surface has a circumferential angular span of less than one hundred and eighty degrees. 
     
     
         6 . The container of  claim 2  wherein the molded recess is adapted and configured for a human thumb and the recess is molded into the external surface of said bottle within the circumferential span of the first internal surface. 
     
     
         7 . The container of  claim 2  wherein the recess is a first recess and which further comprises a second molded recess adapted and configured for the tip of a human index finger, the second recess being centered in the plane of symmetry on a side of the bottle opposite of the first recess. 
     
     
         8 . The container of  claim 1  wherein the plane is a first plane and the interior has a second plane of symmetry passing through the centerline and transverse to the first plane. 
     
     
         9 . The container of  claim 1  wherein the molded recess is a first molded recess, and which further comprises a second external molded recess for receiving the fingertip of a user, the first and second recesses being on opposite sides of said bottle, the first and second recesses being at different axial distances from the topmost surface of said lip. 
     
     
         10 . The container of  claim 1  wherein the bottle is an industry standard longneck bottle. 
     
     
         11 . The container of  claim 1  wherein the non-circular flow channel has an oval shape. 
     
     
         12 . The container of  claim 1  wherein the non-circular flow channel has a figure-8 shape. 
     
     
         13 . A container, comprising:
 a glass bottle defining an interior for holding a quantity of a pourable substance consumable by humans, said bottle including:   a lip defining a cylindrical bore for pouring the substance out of said bottle, the bore being cylindrical about a centerline;   a body with a generally cylindrical base, the base being cylindrical about the centerline; said body including a portion the interior;   a shoulder integral with said body and opposite of said base, said shoulder having two ends with one end blending into said body, said shoulder including an external molded recess for receiving the fingertip of a user; and   a neck having two ends with a narrow end integrally connecting to said lip and the other wider end integrally connecting to the other end of said shoulder, one internal surface of said neck spanning a first circumferential range of said neck and being conically tapered at a first shallower angle relative to the centerline, the opposing internal surface spanning the remaining circumferential range of said neck and being conically tapered at a second steeper angle relative to the centerline, the molded recess being circumferentially located centrally within either the span of the first range or the span of the remaining range.   
     
     
         14 . The container of  claim 13  wherein the first circumferential range is greater than 180 degrees and the second circumferential range is less than 180 degrees. 
     
     
         15 . The container of  claim 13  wherein the second angle is from about ten degrees to about twelve degrees. 
     
     
         16 . The container of  claim 13  wherein the molded recess is adapted and configured for a human thumb and the recess is centrally located within the span of the first range. 
     
     
         17 . The container of  claim 13  wherein the molded recess is adapted and configured for a human index finger and the recess is centrally located within the span of the second range. 
     
     
         18 . The container of  claim 13  wherein said bottle is adapted and configured to contain pressurized liquid.
