Petaloid base for a self-standing container and container therefor

Abstract

A petaloid base (14) for a self-standing container (10) has an approximately hemispherical underlying base contour and a plurality of ovoid foot formations (16) that interrupt and project from the underlying base contour to define a corresponding plurality of feet. Its shape resists stress cracking, maximises capacity relative to the height of the container and reduces the surface area the base and hence material usage in comparison with equivalent known designs.

Description

technical field [0001] The present invention relates to self-standing containers, and more particularly to petal-shaped bases for such containers. Such containers may be blow molded from plastic materials such as polyethylene terephthalate (PET). Background technique [0002] As understood in the art, the generic term "PET" encompasses compositions primarily comprising polyethylene terephthalate, but may also include other materials. For example, a suitable composition may include about 95% polyester synthetic fibers and 5% nylon. These materials may be mixed, or provided in different layers, eg via multilayer injection molding and overmolding, as is known in the art. [0003] Blow-molded PET containers have long been used as beverage bottles. More recently, they have been suggested as kegs for transporting, storing and dispensing beverages such as beer. An example of such a keg is disclosed in WO2007 / 064277. [0004] The example of WO2007 / 064277 is given as background ...
