Abstract
A blow-molded bottle for a carbonated beverage includes a threaded mouth, a cylindrical side wall, a bottom, and a standard fill capacity of 37.5 mL to 105 mL. The bottle is blow-molded from a laminated preform including an outer layer formed from polyethylene terephthalate, an intermediate gas barrier layer formed from a polyamide comprising a dicarboxylic acid component and a diamine component comprising m-xylylenediamine, and an inner layer comprising polyethylene terephthalate. The laminated preform may weigh from about 4 to 16 grams. The polyamide layer provides the bottle with excellent resistance to carbon dioxide, hydrogen, and nitrogen transmission and prevents the degradation of nutrients and flavors.
Claims7
A blow-molded bottle for a carbonated beverage, the bottle comprising:
- a threaded mouth;
- a cylindrical side wall;
- a bottom;
- and
- a standard fill capacity of 37.5 mL to 105 mL;
- wherein the bottle has a ratio of surface area to volume in the range of 1.1 to 1.3 cm−1;
- wherein the bottom portion of the sidewall is curved inward;
- wherein the diameter of the side wall is greater than the diameter of the mouth;
- wherein the bottle is blow-molded from a laminated preform;
- wherein the laminated preform comprises:
- an outer layer formed from polyethylene terephthalate,
- an intermediate gas barrier layer formed from a polyamide comprising a dicarboxylic acid component and a diamine component comprising m-xylylenediamine;
- and
- an inner layer comprising polyethylene terephthalate;
- wherein the laminated preform weighs from about 13 to 16 grams;
- and
- wherein the blow-molded bottle extends the shelf life of the carbonated beverage by 37%-90% when compared to the same beverage stored in a comparative bottle made from a 21 g monolayer preform comprising a single polyethylene terephthalate layer;
- has superior resistance to hydrogen, nitrogen, and CO2 transmission, when compared to a comparative bottle with a standard fill capacity of 75 mL to 105 mL that is blow-molded from a comparative preform comprising a single polyethylene terephthalate layer and a weight of about 14.5 to 21 grams;
- wherein the intermediate gas barrier layer provides 3% to 5% of the total mass of the preform.
