Method for maneuvering and supporting containers during blow molding
A recently filed patent (Publication Number: US20230303287A1) describes a method for maneuvering and supporting a container and its preform during the blow molding process. The method involves supporting the preform and container on a surface by positioning the tamper lip of the finish on the surface. Additionally, the method includes grasping the finish using a gripper that cooperates with a gripper pad on the finish.
In claim 2 of the patent, it is specified that the gripper grasps a groove on the gripper pad, which is located between the upper and lower pad surfaces of the gripper pad. This design allows for a secure grip on the finish during the maneuvering and supporting process.
Claim 3 further explains that the upper and lower pad surfaces extend outward from the outer surface of the finish. This positioning ensures that the outer surface of the finish is closer to the radial center of the finish compared to the upper and lower pad surfaces.
In claim 4, it is stated that the groove on the gripper pad is recessed beneath the outermost portion of the finish's outer surface. This recessed position brings the groove even closer to the radial center of the finish, enhancing the stability of the grip.
Finally, claim 5 combines the features mentioned in claims 3 and 4. The upper and lower pad surfaces still extend outward from the outer surface of the finish, while the groove remains recessed beneath the outer surface. This configuration ensures that both the outer surface and the groove are positioned closer to the radial center of the finish, providing optimal support and maneuverability.
Overall, this patent describes a method for effectively maneuvering and supporting a container and its preform during the blow molding process. By utilizing a gripper and gripper pad with specific design features, the method ensures a secure grip on the finish, enhancing stability and control. This innovation has the potential to improve the efficiency and reliability of blow molding operations in the manufacturing industry.
