A container mold includes: a split mold that has a mold space defining a shape of a body portion of a container; and a bottom mold that has a bottom mold surface defining a shape of a bottom surface of the container and is movable forward and backward with respect to the split mold. The split mold includes a bottom mold reception portion that is communicated with a bottom portion side of the mold space and receives the bottom mold. When the bottom mold is closed with respect to the split mold, a space between a surface of the bottom mold reception portion facing the bottom mold surface and the bottom mold surface is a space that defines a shape of a structure protruding in a radial direction of the container.

A transparent plastic integrally molded goblet has a cup-shaped part, a columnar first leg and a disc-shaped first base integrally molded from transparent plastics. The bottom edge of the cup-shaped part extends downwards to form the first leg. The bottom end of the first leg integrally forms the first base. The cup-shaped part has a circumferential wall which encloses the circumference of a first space. The top edge of the circumferential wall forms an annular first ring frame, and the central part of bottom edge of the first base downwards forms a first convex pin. The integral molding of transparent plastics can enhance the appearance integrity of the goblet, the manufacture of the goblet is easy and the product yield is increased.

The invention relates to a tank of plastics material produced by blow-molding of a parison, incorporating a welding spout, of a shape projecting from its outer surface which has an edge configured to be welded to a corresponding edge of an attached part, the welding spout ending axially, on an inside of the tank, in a shape resulting from contact molding between the parison and a molding component, in which the welding spout ends axially on an outside of the tank in a shape resulting from contact molding between the parison and a molding component.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

The invention relates to a method for manufacturing a container by stretch blow-molding from a preform made of plastic material in a forming unit, the forming unit comprising a mold, an elongation rod that is movable heightwise inside the mold, the method comprising, in succession, a pre-blow-molding step and a blow-molding step, the method also comprising a step of boxing of a handle, a rising phase of the elongation rod being initiated before the blow-molding step, the boxing step being initiated after the rising of the elongation rod, the handle being formed on the extension axis of the elongation rod.

A production device for a fuel tank, having two or more built-in components attached to an inside of a fuel tank body when the fuel tank body is formed, includes: jigs configured to have the built-in components placed thereon; and a feed robot, as a feed device, configured to feed the built-in components, along with the jigs having the built-in components placed thereon, to a position below molding dies. The feed device may feed the jig, having the built-in components placed thereon, to the position via a subsurface feed path leading to the position.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

The invention relates to a mold for a container that includes a mold base. The mold base includes a peripheral face, a central dome, and a central well formed in the dome and extending along a frustoconical sidewall from a top edge of the dome having a top diameter, to a bottom having a bottom diameter smaller than the top diameter. The mold also includes a stretching rod that ends with a hemispherical distal end having a radius, the value of which is between that of the bottom radius and that of the top radius of the central well. When the rod is in the bottom position, it is separated from the sidewall of the central well by a distance smaller than the distance that separates it from the bottom of the well.

A displacement device for moving a truncated cone at a base of a container from an as-blown position to a displaced position. The base includes a deep base ring between a standing surface and the truncated cone. The displacement device includes a collar sized and shaped to be received within the deep base ring. A plunger includes a head at an end of a shaft extending through the collar. The head is sized and shaped to be received within the receptacle of the collar. The plunger is movable from a retracted position, at which the head is seated within the receptacle, to an extended position at which the head extends out from within the receptacle to allow the head to contact the truncated cone and move the truncated cone from the as-blown position to the displaced position.
