Reclosable plastic container having improved opening release
摘要:
A reclosable plastic container is formed having a cover hingedly attached to a base and having an interlocking structure such that the cover is held on the base when the container is closed. Release tabs are formed on each of the cover and base adjacent one another and having camming surfaces on each tab which extend therefrom toward the other tab. The camming surfaces on the tabs intersect in a fulcrum such that when the user presses the tabs together, the tabs rotate about the fulcrum to pull the cover and base apart. The camming surface on each tab may be formed as a ridge formed integrally with the tab. Reinforcing ridges, extending away from the plane of the tab in a direction opposite to that of the camming surfaces, are also preferably formed in the tab to provide structural rigidity so that the tabs do not substantially bend or flex when they are pressed by the user. The tabs allow a securely closed container to be easily opened by one hand of the user.
