Abstract: A manufacturing machine for plastic containers having an upper and a lower portion with respective joining edges, comprising a first fixed base with an axle mounted thereto, a circular platform mounted upon the axle, and a plurality of welding stations mounted over the circular platform. Each welding station comprises a second fixed base that receives the lower portion of the container and a movable head having suction heads that receives the upper portion of the container therein, and it slides up and down upon a column mounted to the circular platform. The present invention further comprises a fusion station that acts upon the joining edges of the upper and lower portion and it comprises a hot plate that is positioned between the joining upper and lower edges and raises the temperature of the material, thus fusing the material. A robot loads new upper and lower portions into the welding station.

Abstract: A method of producing plastic containers comprising an opening having a smaller diameter than that of the base, and the container thus produced, comprising the steps of producing a lower portion and an upper portion of a container separately, using a resin injection process, and welding the lower and upper portions using a hot plate process. The resulting container comprises an opening having a first diameter that is smaller than a second diameter of the base or a longest linear dimension of the base. The lower portion and the upper portion are connected to each other along peripheral edges by means of a weld seam. The lower portion and the upper portion each comprise straight peripheral socketing edges comprising two surfaces which form a right angle and which define an edge at the intersection thereof.
