Hermetically sealable containers and method of sealing. |
摘要 |
A container body (10) made of thermoplastic materials, and of uniform bottom and side wall thickness, after being filled with a hot liquid (50), is then hermetically sealed by a flat closure disc (55) adhesively contacting a peripheral lip (26, 28) formed around the top of the body. The bottom wall (20) of the container body (10) is formed with annular grooves (22) to define a flexible diaphragm which flexes inwardly upon cooling of the liquid (50) to substantially dissipate the internal vacuum which is formed in the container head space (62); the suction is similarly relieved by inward flexing of the disc (55). The bottom (20) of the container body has a reinforced pedestal base (14) formed with stacking ledges (25) to facilitate nesting of empty bodies (10) for shipment and storage.
