    摘要： A container comprising a body with a rim (6) of which at least the upper surface is of a first plastics material, and a flexible closure (8) of which at least the under surface is of a second plastics material different from the first, the body and closure being attached together by a heat seal formed between the said surfaces thereof, wherein the heat seal includes radially inner and radially outer ears (18,16) formed during the heat sealing operation by heat and pressure, each ear having a core (22,20) which is formed of the first plastics material and is joined integrally to the rim by a thin root (34,32), and an envelope (26,28) which is formed of the second plastics material integrally with the closure and which envelops the core and tapers in beneath the core to a position adjacent to the thin root of the core, both ears lying on the top of the rim around at least a substantial part of the container periphery, the closure having a free portion (10) located outside the heat seal for grasping by the user, and the closure and both ears being manually peelable together away from the rim by use of the free portion.
