  • Patent number: 11697241
    Abstract: A blow mold system including a mold body and a base portion. The mold body includes a central bore extending from a first end of the mold body to a second end of the mold body along a longitudinal axis. The first end is configured to receive a mold preform. The base portion includes a recess, and the base portion is arranged at the second end of the mold body such that the central bore and recess define a blow mold cavity in which a container may be formed from the mold preform. In embodiments, the blow mold system has at least two interchangeable base portions that allow for containers with differently-sized or differently-shaped necks to be formed.

  • Patent number: 10293538
    Abstract: A blow-molding method for forming a squeezable or tubular plastic container is provided. The method includes molding a preform having a sidewall, an interior cavity, an open end, a closed end, and a neck adjacent the closed end of the preform. The neck of the preform has an engagement structure. The method includes providing a blow mold system including a blow mold cavity. The method includes placing at least a portion of the preform into the blow mold cavity, and blow molding a one-piece container body from the preform by inflating the preform within the blow mold cavity. The container body has an open end, a closed end and a neck adjacent to the closed end. Wherein the open end of the container body is formed from the open end of the preform, and the closed end of the container body is formed from the closed end of the preform.
