Containers and Materials With Improved Punctureability

摘要

The present description includes containers having an improved puncture design that can be punctured without substantial deformation of the container. Such containers are particularly suitable for use in preparing beverages using automatic machines, particularly those used for preparation of single serve beverages. Also provided are thermoplastic materials having improved punctureability for use in containers, containers for preparation of a beverage, and methods for preparing a beverage using such containers.

主权项

1. A container comprising:
a substantially circular base; a frustoconically shaped wall extending from an edge of the base and defining a cavity therein; and a stacking shoulder which intersects and extends laterally from the wall; wherein the base comprises an annular support structure having a continuous puncture region therein, the annular support structure being positioned an effective distance from the edge of the base to increase the punctureability of the base; and wherein the continuous puncture region is sized and shaped to permit a puncture therein without interference and without substantial deformation of the container.
