<p>A packaging container (10) for photosensitive film has a detent locking and unlocking feature that provides light-tight closure of the container compartment to protect the product from the penetration of light. A protuberance (20) formed in the container compartment (12) interlocks with a notch (24) formed in the closure (22) for preventing axial movement of the closure (22). The interlocked protuberance (20) and notch (24) form the light-tight packaging container (10). <IMAGE></p> |
