Abstract
Abstract A disposable container suitable for retaining liquids comprises two opposed container sections (50), each having a peripheral ring-like flange (52) about a recess (54) with the flanges (52) being sealed therebetween. The recesses (54) of the opposed container sections (50) define a common central cavity and the flanges (52) include a throat opening (56) into said cavity (54) through which product within the cavity (54) can be dispensed. The throat (56) is at least partially defined by the opposed container flanges (52) and each container section (50) is of a thermoformable plastic material. These container sections (50) are originally formed from flat strip packaging material having diecut side edges with the strip defining individual container body sections. A tapered neck portion (48) of each body section (50) accommodates dispensing of the contents and preferably a hot melt adhesive (42) secures the opposed container sections (50).
