Low weight container closure

Abstract

A container closure comprising a top wall portion and a skirt portion depending from the top wall portion is provided. The skirt portion can include corrugation on an interior and exterior thereof, and the corrugation can reduce the weight of the container closure and provide strength of the skirt portion.

Description

FIELD OF INVENTION[0001]The present invention relates generally to a low weight container closure. More particularly, the present invention relates to a container closure having corrugations or grooves that make up the interior and exterior of a skirt of the container closure.BACKGROUND OF THE INVENTION[0002]Container closures are common in consumer markets. Typically, closures can be injection molded from a plastic material or the like. Such closures can be used for sealing containers, e.g., bottles of juice, milk, soda pop, and the like. One known closure includes a circular top wall portion and an annular skirt depending from the top wall portion. The closure may include tamper indicating means, such as a tamper-indicating band that depends and is separable from the annular skirt.[0003]Generally, closures are formed as snap-type closures or threaded closures. Snap-type closures can secure to a container by one or more inwardly projecting elements that snap over complementary, out...

Benefits of technology

[0009]According to the present invention a closure for use with an associated container is provided. The closure can include a top wall portion and a skirt portion that depends from the top wall portion. The skirt portion can include corrugation on the interior and exterior thereof such that the corrugation can reduce the weight of the container closure and provide strength to the skirt portion.

[0011]Accordingly, it is a benefit of the present invention to provide a closure that uses less material than has been traditionally required to manufacture and produce a closure of a particular size.

[0012]It is a further benefit of the present invention to provide a closure that maintains its necessary strength while reducing the amount of material required to manufacture and produce the closure.

[0013]It is another benefit of the present invention to short weight a closure to reduce the amount of material required to produce a particular closure.

[0017]In accordance with the present invention, all of these benefits as well as others not herein specifically identified, are generally achieved by the present low weight container closure.

Problems solved by technology

Moreover, the cost of producing the closure is often directly related to the size thereof because material is generally the largest cost component of the closure.

However, there are drawbacks to such closures.

As explained above, the cost of producing a closure is often directly related to the size of the closure because material is generally the largest cost component of the closure.

Accordingly, when a closure is manufactured, the cost of manufacturing and producing the closure can be significant.

One of the problems associated with reducing the amount of material used to produce a particular closure is that often the strength of the closure is reduced as a result.
