ABSTRACT:
An improved locking arrangement for blister packaging in which a male element with an enlarged head is received in snap lock engagement in a female element past a reduced annular shoulder in the female element. The male element has its head enlarged about a circumferential segment, preferably not greater than 270.degree. so as to facilitate entry of the male element into the female element without reducing the forces required for unlocking yet permitting the male element to be sufficiently strong to resist crushing on the application of axial finger pressures to the male element on manual closing of the packaging.
