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.
Abstract: A package is disclosed to enclose bakery items, particularly cakes. The package has a transparent, light-weight, domed plastic cover and a flat base upon which the cake is received. The cover has catch means provided on its side walls at circumferentially spaced locations to be engaged by U-shaped hook members partially cut from outwardly extending projections from the base. The hook members are bendable upwardly to positions in which their blights overlie and engage catch means on the cover to couple the cover to the base.
