Beverage container with easy label removal

Abstract

A beverage container or plastic bottle that allows easy label or film removal is provided. The beverage container includes a shoulder portion, a base portion, a body portion extending between the shoulder portion and the base portion, the body portion having a reinforcing concave rib circumferentially formed on the body portion, the concave rib having an asymmetrical shape at a vertical cross-section of the concave rib, and a heat shrink film disposed over the body portion, the heat shrink film having an edge disposed over the concave rib.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a plastic beverage container or bottle for storing liquids such as refreshing beverages or carbonated beverages. In particular, the invention is directed to a plastic beverage container or bottle with a heat shrink film that can be easily peeled off or removed.BACKGROUND[0002]Plastic bottles, such as PET bottles, are widely known as beverage containers. This type of bottle is provided with, from the top of the bottle, a mouth portion, a shoulder portion, a body portion, and a base portion. A concave rib is often formed about the entire circumference of the body portion to provide a lateral strength to the bottle. Typically, upper and lower concave ribs are formed in the body of small bottles with not more than 500 ml, and an additional concave rib is often formed in the middle section of large bottles above 1500 ml.[0003]Bottles provided to consumers are often covered with a film or a shrink-wrap label printed with, for ex...

AI Technical Summary

Benefits of technology

[0008]It is accordingly an object of the invention to provide a beverage container or bottle that addresses the aforementioned problems. In one aspect, a beverage container or bottle is provided to enhance the design of the shoulder and base portions. It is another object of the invention to provide a beverage container or plastic bottle with a label or film that can be easily removed while maintaining the strength of the bottle. A beverage container includes a shoulder portion, a base portion, a body portion extending between the shoulder portion and the base portion, the body portion having a reinforcing concave rib circumferentially formed on the body portion, the concave rib having an asymmetrical shape at a vertical cross-section of the concave rib, and a heat shrink film disposed over the body portion, the heat shrink film having an edge disposed over the concave rib.

Problems solved by technology

By wrapping the upper edge of the label around the conical shoulder portion, it is more difficult for the label to move or peel off compared to just wrapping it around a flat surface of the cylindrical body.

However, a decorative design has generally not been formed on the body portion, the shoulder portion, or the base portion because any decorative design formed on those portions would be covered by a label defeating the purpose of the design.

However, if the upper edge of the label were located on a flat surface of the shoulder portion, the label would easily move and slip off the bottle.

However, such an arrangement would make it difficult for consumers to insert their fingernails in the concave ribs and to pull off the upper edge of the label.

Consequently, peeling off the label becomes more difficult.
