A recently filed patent (Publication Number: US20230312175A1) describes a plastic container with a unique handle design. The container consists of a container body that forms a filling volume and a reach-through opening that serves as a handle. The handle is created by a partial region of the container body, and a handle insert is placed within the reach-through opening.

The handle insert is designed with a parting plane, which allows it to be formed in two parts. It consists of a first shell and a second shell, with the parting plane running parallel to the mold parting plane of the container. The first shell and the second shell have contact surfaces that face each other and can be connected through methods such as gluing or welding. Alternatively, they can be connected via a snap-in connection.

The reach-through opening of the container includes a circumferential projection, and the handle insert has a first pressing element and a second pressing element. These pressing elements rest under pretension on the projection, providing stability and strength to the handle.

The container also features a circumferential connection seam within the reach-through opening, which can be formed as part of the projection. The handle insert may have reinforcing ribs, which are positioned between a pressing element and an associated surface, enhancing the overall durability of the handle.

The plastic container described in the patent can be produced through stretch blow-molding or injection molding processes. It can be made from various types of plastics, including PET, PET-G, HDPE, LDPE, PP, PS, PVC, PEN, PHA, PHB, PEIT, PCTG, LLDPE, MDPE, and their copolymers. Additionally, bioplastics such as PLA or PEF, filled plastics, and mixtures of these plastics can also be used.

One notable aspect of this invention is that both the handle insert and the plastic container are made of the same material, which simplifies the manufacturing process and ensures compatibility between the components.

Overall, this patent presents a novel design for a plastic container with an integrated handle, offering improved strength and stability. The use of a handle insert and various connection methods enhances the durability of the handle, making it suitable for a wide range of applications.
