ABSTRACT:
A cap for a molded plastic container has a cover section and a seating section which are provided with a tear strip for obtaining drinking or pouring access to the contents of the container without removal of the cap. The cover section has a centrally raised portion and a portion which slopes downwardly and radially outward from the centrally raised portion and terminates in a circumferentially extending seating portion. The latter includes an outer, downwardly extending skirt which embraces the upper end of the container. Two parallel slots extend part way up from the edge of the skirt and terminate in a groove which extends to the edge of the cover section and then follows the surface of the cover section in a generally radial direction to form a tear strip having a continuous, wedge-shaped configuration. The two parallel slots form a tab for grasping the tear strip with the fingers. Because of the shape of the cover section, a twisting motion of the wrist easily tears away the wedge-shaped section along the lines of the groove to provide access to the contents of the container without the need for removing the cap. A fulcrum to enhance tearing action is established by a raised circumferential ridge of the cap against which the container is seated and another fulcrum is established at the juncture of a wall portion of the cap seating section with the sloping portion of the cover section.
