Abstract

A container and closure are described. The container has a circular sidewall with a bottom and an open end defining a volume for containing a liquid, the sidewall having (i) a reinforced rim at the open end, (ii) a lid seat integrally formed in the sidewall and offset from the open end, (iii) a comfort zone extending along the sidewall from the bottom to the open end and (iv) a rim tab located on the inside of the container sidewall at the comfort zone adjacent the open end. The rim tab extends beyond the open end of the container. The closure is a circular substrate having (a) a diameter to seat in the lid seat of the container, (b) a plurality of peripheral tabs extending beyond the diameter of the substrate and (c) a pull tab located near an outer edge of the substrate which when pulled provides an opening through which liquid can pass when the closure is seated in the lid seat of the container. The peripheral tabs are preferably (1) a first tab having a slotted opening to accept the rim tab and (2) two or more talon tabs, each having an opening adapted and located to engage the rim of the container.
