  • Blow Molded Plastic Container Assembly With Improved Lid Sealing
    Publication number: 20100200605
    Abstract: A plastic container that is preferably formed using a blow molding and trimming process includes a container main body portion and a lid mounting portion. The lid mounting portion includes a sealing flange and a flexible transition portion connecting the sealing flange to the container main body portion. The flexible transition portion preferably has at least one notch defined therein so as to form a hinge permitting downward movement of the sealing flange when a lid is secured on to the container. In another embodiment, more than one notch is provided defining multiple hinges that provide a compound hinge effect in order to reduce stresses on the molded plastic material during use of the container.
