Abstract
A child-resistant package includes first and second elements having base walls with rectangular peripheries, continuous peripheral walls extending around the peripheries, locking projections or tabs on opposed sections of the peripheral walls, and cylindrical walls extending from the base walls within the peripheral walls and having thread segments. The second element is threadable onto the first element to bring the peripheral walls into aligned abutment and the locking tabs into engagement with the locking projections to resist unthreading of the elements. The peripheral wall of the second element is inwardly flexible and resilient adjacent to the locking tabs to permit manual movement of the locking tabs inward from the locking projections so that the elements can be unthreaded from each other.
Claims22
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.

- 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,
- at least one of said locking projections and said locking tabs having cam surfaces for camming said tabs inwardly as said first and second elements are threaded to each other, and abutment surfaces for engagement between said projections and tabs to resist unthreading of said elements absent inward flexure of said peripheral wall of said second element, and
- a label extending at least from said base wall of said second element around abutting sections of said peripheral walls onto said base wall of said first element, such that said label must be severed to permit unthreading of said elements to provide tamper indication for said package.
