Benefits of technology

[0016]Finally, it is a benefit of the present invention to use corrugation or grooves to provide strength to a 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.

Embodiment Construction

[0031]While this invention is susceptible of an embodiment in many different forms, there are shown in the drawings and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention. It is not intended to limit the invention to the specific illustrated embodiments.

[0032]Embodiments of the present invention include a low weight container closure. The closure can be short weighted so as to minimize the weight and amount of material used to produce such a closure. Furthermore, the closure can retain its strength required for repeated handling, application, and removal of the closure. In embodiments of the present invention, the closure can include corrugation, grooves, protrusions, ridges, and / or zig-zags that make up both the interior and exterior of the closure's skirt.

[0033]In embodiments of the claimed invention, the closure, including a top wall portion...

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...
