A rigid connecting device for connecting the upper and lower surfaces inside an oil tank includes a connecting rod. The upper and lower sides of the connecting rod are each provided with a connecting end surface. The connecting end surface is provided with material-passing hole. The outer surface of the rigid connecting device is covered with high-density polyethylene. The upper and lower surfaces of the oil tank are connected by a connecting rod, and such arrangement is locally applied to areas where the rigidity of the oil tank is poor, so there are more effective space. The part of the rigid connecting rod contacting with the oil fuel is made of high-density polyethylene, so the requirements of strength and anti-corrosion can be satisfied.

Machine for forming containers made of thermoplastic material by blow-molding preforms obtained by means of injection/molding within the machine, for which at least one longitudinal direction for feeding of the preforms between the stations thereof is defined, said machine including: an injection unit provided with a longitudinal injector; a station for molding the preforms, comprising a mold with a predefined number of cavities for injection/molding of preforms; a station for blowing the preforms, comprising a blowing assembly for forming finished containers; said blowing assembly comprising a smaller number of blowing cavities than the number of injection/molding cavities in the mold and being displaceable in both senses of the longitudinal direction on fixed longitudinal guides.

A base assembly configured to cooperate with an injection blow molding machine for forming a polymeric container from a preform by injection blow molding. The base assembly includes a base insert defining a base mold configured to form a base of the polymeric container during injection blow molding. The base insert is slidably seated within the base assembly. The base insert is slidably movable between a retracted position and an extended position during injection blow molding of the polymeric container.

A container forming assembly and method includes receiving a parison within a cavity of a mold, enclosing the parison within the mold having a wall with a recess, inflating the parison in the mold to form a blow molded container where the blow molded container has a sidewall, a movable region formed at the recess, and a hinge circumscribing an interface between the sidewall and the movable region, and moving or repositioning the movable region toward an interior of the blow molded container about the hinge before filling. The movable region can form a deep-set grip. Further, multiple movable regions can be provided, each of which may form respective deep-set grips. The container shape can be symmetrical or asymmetrical.

To prevent core misalignment when performs are stretched during blow molding, provided is a blow molding device that blow molds a preform into a container in a forming mold. The blow molding device includes a support pin that is disposed in the forming mold. The support pin includes a head that supports a bottom portion of the preform, and a shaft that is connected to the head and that is displaceable upward and downward in a direction of an axis of the preform. The head is provided, at one end thereof supporting the bottom portion of the preform, with a concave portion for receiving at least a part of the bottom portion.
