    Abstract: A process for blow-molding a container, the container having a handle, whereby the process includes the steps of: (i) introducing a preform into a mold cavity and stretching the preform with a stretch rod; (ii) increasing the pressure within the preform so that the preform expands within the mold cavity in a first blowing step, the pressure in the first blowing step is from 1 to 10 bar; (iii) inwardly moving jaws within the mold cavity so that the expanding preform is partially gripped between the jaws in the handle region; (iv) subsequently increasing the pressure within the preform wherein the maximum pressure in the second blowing step is greater than 10 bar, so that the preform expands to the limits of the mold cavity in a second blowing step to form a container; and wherein the inward movement of the jaws is completed within the first blowing step.

  • Publication number: 20140054829
    Abstract: A method of making a container includes the step of providing a preform having a body defining an interior cavity. The body has an end portion and an end feature protruding from the end portion. The preform is placed into a mold. The mold has a mold cavity for receiving the preform body and a feature cavity for receiving the end feature. A stretch rod is inserted into the interior cavity of the preform to a position adjacent the end feature, whereby the stretch rod will retain the end feature in the feature cavity. The preform is blow molded into a finished product. The stretch rod retains the end feature in the feature cavity during the blow molding step.

  • Patent number: 8517195
    Abstract: A method of producing a plastics milk container involves blow molding a parison in a mold tool configured to produce a container having a body with a handle eye which defines a central axis extending in a first direction through the body, and a footprint with a longitudinal axis extending in a direction perpendicular to the first direction. The footprint defines four major sides and four major corner regions, each corner region arranged between a respective two of the major sides. The longitudinal axis extends through a center point of the footprint, and the maximum radial extent of the footprint from the center point is greatest where the footprint intersects the longitudinal axis, corresponding to the location of two of the corner regions, so that the extent of parison stretch away from the mold tool split line is less than the extent of parison stretch along the split line.
