High strength bottle

Abstract

A bottle with improved strength is provided. The bottle can have a liquid holding capacity of at least 2.5 gallons and can exhibit a drop impact resistance of at least 3 feet as measured by ASTMD 2463-95. The bottle can be formed from a substantially BPA-free material. The bottle can be used in liquid dispensers, such as water coolers.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention is directed to bottles having handles. More particularly, the present invention is directed to large capacity bottles having handles and being suitable for use in liquid dispensers, such as water coolers.[0003]2. Description of the Related Art[0004]BPA-based polycarbonates have long been used to produce various types of food and beverage containers. However, due to some reports that BPA-based polycarbonates may have negative health effects, an emphasis has recently been placed on producing containers that are “BPA-free.” In particular, the container industry has focused on the production of beverage bottles, where leaching of BPA into the beverage has been a concern due to the prolonged exposure of the beverage to the BPA-based polycarbonate. However, most of the bottle industry's BPA-free focus has been on smaller bottles with a capacity of less than one liter.[0005]Despite the desire to produce beverage bottles t...

AI Technical Summary

Benefits of technology

[0008]Another embodiment of the invention is directed to a substantially BPA-free bottle comprising an outlet at a first end of the bottle, a base at a second end of the bottle, and a main body located between the outlet and base. The bottle defines a central longitudinal axis extending in a longitudinal direction between the first and second ends of the bottle. Furthermore, the main body comprises a well panel and a handle, wherein the well panel at least partly defines a recessed well and the handle spans

Problems solved by technology

However, due to some reports that BPA-based polycarbonates may have negative health effects, an emphasis has recently been placed on producing containers that are “BPA-free.” In particular, the container industry has focused on the production of beverage bottles, where leaching of BPA into the beverage has been a concern due to the prolonged exposure of the beverage to the BPA-based polycarbonate.

Despite the desire to produce beverage bottles that are BPA-free, many materials that could potentially replace BPA-based polycarbonates exhibit deficiencies in one or more important characteristics, such as strength, toughness, chemical resistance, clarity, heat resistance, and / or processability.

Currently, there are no BPA-free bottles having a large capacity (e.g., at least 2.5 gallons) that are sufficiently designed to exhibit the desired characteristics (e.g., strength, toughness, chemical resistance, heat resistance, and / or clarity) sought in large capacity bottles.
