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° 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.
Dispositif de fermeture amélioré pour emballage-coque, dans lequel un élément mâle à tête élargie est encliquetable avec un élément femelle au-delà d'un épaulement annulaire réduit dans l'élément femelle. La tête de l'élément mâle est élargie autour d'un segment périphérique d'au plus 270 degrés, de manière à faciliter l'entrée de l'élément mâle dans l'élément femelle sans pour autant diminuer la force nécessaire pour ouvrir l'emballage, tout en faisant en sorte que l'élément mâle soit suffisamment solide pour ne pas être écrasé lorsqu'une pression axiale des doigts est appliquée pour fermer l'emballage.
