Latest Patents
One of Hetherington's latest patents is focused on the manufacture of plastic containers. This invention relates to an improvement in a method for thermoforming containers from thermoplastic materials. The method involves forming the rim of the container as an integral part of the pre-form, which is created by introducing thermoplastic material into a closed space and mechanically compressing it. The innovation enhances the uniformity of flow of the thermoplastic material and utilizes a closed space defined by specific surface roughness. This process is particularly useful for manufacturing containers for products like margarine from polyethylene or polypropylene.
Another significant patent is for a process that produces a heat-weakened strip in polyolefin film. This continuous process involves directing heat from two longitudinally aligned sources to opposing sides of a travelling web of cross-lapped oriented polyolefin film. The resulting heat-weakened strip has a tensile breaking strength suitable for packaging applications, such as slurry explosives.
