Abstract
A polymeric container with a finish defining an opening. A base is at an end of the polymeric container opposite to the opening. A plurality of base lobes are spaced apart about an axial center of the base. Each one of the plurality of base lobes includes a generally horizontal portion, a generally vertical portion, and a curved portion between the generally horizontal portion and the generally vertical portion. The polymeric container is made of at least 35% recycled material.
Claims35
A polymeric container comprising:
- a finish defining an opening;
- a base at an end of the polymeric container opposite to the opening;
- a plurality of base lobes included with the base and spaced apart about an axial center of the base;
- and
- a counter-stretch rod receptacle at an axial center of the base and defined by the plurality of base lobes, the counter-stretch rod receptacle is configured to receive a counter-stretch rod of a blow-molding machine during formation of the polymeric container;
- and
- wherein the polymeric container is made of at least 35% recycled material.
A polymeric container comprising:
- a finish defining an opening;
- a base at an end of the polymeric container opposite to the opening;
- a plurality of base lobes included with the base and spaced apart about an axial center of the base;
- and
- a circular outer edge of the base surrounding the plurality of base lobes, an outer end of each one of the plurality of base lobes contacts the circular outer edge;
- wherein each one of the plurality of base lobes includes a generally horizontal portion, a generally vertical portion, and a curved portion between the generally horizontal portion and the generally vertical portion;
- wherein the plurality of base lobes are 54%-57% of a total surface area of the base within the circular outer edge surrounding the plurality of base lobes;
- and
- wherein the polymeric container is made of at least 35% recycled material.
