ABSTRACT:
Difficulties in removing a film-like seal (14) from the access opening (12) of a container (10) may be avoided in a container and cap construction including a container (10) whose access opening (12) has an edge (20) of circular shape and of a particular inside diameter, a cap (16) for the opening (12), snap-fit components (28, 30) or threads (140, 142) for removably holding the cap (16) on the container (10) to occlude the access opening (12), a membrane or foil-like seal (14) bonded to the container (10) about the access opening (12) to be free of the cap (16) and at least one cutting tooth (50, 104) carried by the cap (16) and displaced from a rotation point (54) on the cap (16) about which the cap (16) may be rotated relative to the access opening (12) a distance equal to or slightly more than one-half of the particular diameter.
