a disposable container suitable for retaining liquids comprises two opposed container sections , each having a peripheral ring like flange about a recess with the flanges being sealed therebetween . the recesses of the opposed container sections define a common central cavity and the flanges include a throat opening into said cavity through which product within the cavity can be dispensed . the throat is at least partially defined by the opposed container flanges and each container section is of a thermoformable plastic material . these container sections are originally formed from flat strip packaging material having diecut side edges with the strip defining individual container body sections . a tapered neck portion of each body section accommodates dispensing of the contents and preferably a hot melt adhesive secures the opposed container sections . the plastic containers are formed by intermittently advancing , in timed sequence , two strips through separate thermoforming operations where each strip is shaped to form a series of half containers and thereafter the strips are married and secured for subsequent operations . the invention also includes an apparatus and process for forming , filling and sealing the containers by advancing the packaging material through a number of stations along a predetermined path . the formed container is shaped to reduce inadvertent tipping thereof when supported in a free - standing disposition .
