Abstract
A system for simultaneously forming and filling a polymeric container with a product. The system includes a mold defining a container profile and a mold vacuum vent extending from the container profile to an upper surface of the mold. A striker plate is secured to the upper surface of the mold. The striker plate defines a striker vacuum vent that aligns with the mold vacuum vent to allow some of the product to be pulled by vacuum out of the mold through the mold vacuum vent and the striker vacuum vent.
Claims20
A system for simultaneously forming and filling a polymeric container with a product, the system comprising:
- a mold defining a container profile and a mold vacuum vent extending from the container profile to an upper surface of the mold;
- and
- a striker plate secured to the upper surface of the mold, the striker plate defining a striker vacuum vent that aligns with the mold vacuum vent to allow some of the product to be pulled by vacuum out of the mold through the mold vacuum vent and the striker vacuum vent.
A method for simultaneously forming and filling a polymeric container, the method comprising:
- injecting a product into a preform seated in a mold to simultaneously form the container from the preform and fill the container with the product;
- and
- generating a vacuum to draw excess product out of the mold through a mold vacuum vent defined by the mold and a striker vacuum vent of a striker plate attached the mold.
A system for simultaneously forming and filling a polymeric container with a product, the system comprising:
- a mold defining a container profile and a mold vacuum vent extending from the container profile to an upper surface of the mold;
- a striker plate secured to the upper surface of the mold, the striker plate defining a striker vacuum vent that aligns with the mold vacuum vent to allow some of the product to be pulled by vacuum out of the mold through the mold vacuum vent and the striker vacuum vent;
- a vacuum generator configured to generate the vacuum that pulls some of the product out of the mold through the mold vacuum vent and the striker vacuum vent;
- a knock-out vessel configured to regulate the vacuum and receive the product pulled by the vacuum out of the mold;
- and
- a vacuum valve between the striker plate and the knock-out vessel, the vacuum valve configured to sync the vacuum with consecutive container forming and filling processes.
