Abstract:
1. A child-resistant package that includes: a first element having a base wall with a rectangular periphery, a continuous peripheral wall extending around said periphery, at least a pair of locking projections internally disposed on opposed sections of said peripheral wall, and a cylindrical wall extending from said base wall in the same direction as said peripheral wall of said first element and within said peripheral wall of said first element and having at least one first thread segment, and a second element having a base wall with a rectangular periphery and a continuous peripheral wall extending around said rectangular periphery, a pair of locking tabs centrally extending from opposed sections of said peripheral wall, and a cylindrical wall extending from said base wall in the same direction as said peripheral wall of said second element and within said peripheral wall of said second element and having at least one second thread segment, said second element being threadable onto said first element by means of said cylindrical walls and said first and second thread segments to bring said peripheral walls into aligned abutment and said locking tabs into engagement with said locking projections to resist unthreading of said elements, said peripheral wall of said second element being inwardly flexible and resilient adjacent to said locking tabs to move said locking tabs inward from said locking projections so that said elements can be unthreaded.
