Prototype Improvements - Tabs

From testing my prototype i realised that the current tabs used are not strong enough to hold the top of the box together.

With their current simple square design they have a habit of sliding out of the slot. Looking at this issue I returned to looking at other tab designs that would work better for my packaging.

As I wanted someway for the tabs to hook inside the slots to avoid them slipping out, this seemed a suitable solution. Using this style of tab allows it to hook inside the slot and at the very least provides much better support than a flat square tab. This style of tab will be worked with to make it suitable for my design and should improve the quality and strength of the lid of the package.
