Abstract: A container and a lid for closing it are disclosed. The container has an open end, a closed end and a peripheral sidewall therebetween. The peripheral sidewall has a rolled rim at the edge thereof adjacent the open end of the container. The lid has a dome-shaped structure. A peripheral rim curl is provided for locking the lid to the rolled rim of the container to close the open end. The lid also has a central region and a plurality of arched struts extending radially between the central region and the peripheral rim curl. At least one tabular hinged drinking region is provided in the lid. The tabular hinged drinking region is structured and arranged to be depressed into the container, thereby providing at least one flow-through opening in the tabular hinged drinking region of the lid. Preferably, the depressed tabular hinged drinking region is self-locking.

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.

Abstract: The preparation of N-(aryl)-1,2,4-triazolopyrimidine-2-sulfonamides by the coupling of substituted 1,2,4-triazolopyrimidine-2-sulfonyl halides with aryl amines of substantially reduced nucleophilic reactivity is facilitated by conducting the reaction in the presence of a pyridine base and a catalytic amount of dimethyl sulfoxide.
