ABSTRACT:
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.
