Closure and container package with child-resistant and non-child-resistant modes of operation

A package having child-resistant and non-child-resistant modes of operation, which includes:

• a container having an end with an open mouth surrounded by a container wall with a central axis and an outer surface surrounding said mouth, and at least one first lock element extending radially outwardly from said wall, and
• a closure that includes an annular base wall having inner;
• and outer peripheral edges, a cylindrical skirt extending from said outer peripheral edge of said base wall, at least one second lock element on said skirt, and a projection extending axially from said inner peripheral edge of said base wall in a direction opposite from said skirt, said projection having an annular sidewall spaced radially inwardly from said outer peripheral edge of said skirt,
• said closure being adapted to be secured to said container in a child-resistant mode of operation with said at least one second lock element on said skirt releasably engaged with said at least one first lock element on said container wall, and with said inner peripheral edge of said base wall in engagement with said outer surface of said container wall to bias said lock elements in engagement with each other and to seal said package,
• said closure being adapted to be secured to said container in a non-child-resistant mode of operation with said annular sidewall of said projection received in plug-sealing engagement within said container mouth,
• said closure including a wall extending from said outer peripheral edge of said base wall, said wall being of sufficient length to radially outwardly cover said at least one first lock element on said container by extending axially below said at least one first lock element when said projection is received within the container mouth,
• said container wall being radially inflexible around said mouth, and said closure being adapted to flex radially outwardly around said base wall for urging said second lock element against said first lock element,
• said wall of said container wall including a radially outwardly extending external bead surrounding said mouth and stiffening said container wall against radial flexure around said mouth, said bead having a conical outer surface for engagement by said inner peripheral edge of said base wall in said child-resistant mode of operation to flex said base wall radially outwardly.

• said closure being adapted to be secured to said container in a child-resistant mode of operation with said at least one second lock element on said skirt releasably engaged with said at least one first lock element on said container wall, and with said inner peripheral edge of said base wall in engagement with said outer surface of said container wall to bias said lock elements in engagement with each other and to seal said package,
• said closure being adapted to be secured to said container in a non-child-resistant mode of operation with said annular sidewall of said projection received in plug-sealing engagement within said container mouth,
• said closure including a wall extending from said outer peripheral edge of said base wall, said wall being of sufficient length to radially outwardly cover said at least one first lock element on said container by extending at least axially even with said at least one first lock element when said projection is received within the container mouth,
• wherein said wall extends from said outer peripheral edge of said base wall in a direction opposite from said skirt for engaging said at least one first lock element on said container in said non-child-resistant mode of operation.
