A container body made of thermoplastic materials, after being filled with a hot liquid, is then sealed by a flat closure disc adhesively contacting a peripheral lip formed around the top of the body. The bottom of the container body is formed with annular grooves to define a diaphragm which flexes inwardly with the closure disc upon cooling of the hot filled liquid to substantially dissipate the high internal vacuum which is formed on the container head space. The bottom of the container body has a reinforced pedestal base formed with stacking ledges to facilitate nesting of empty bodies for shipment and storage.
