The opening of the box has a perforation at the bottom. The sleeve then opens up to present the contents held within. This happens because the gravity facilitates the small packs of candies or chewing gums to clump up together. The customer then grabs and goes – it’s that simple! The function of auto lock bottom is that the base needs to be strong in order to stop the contents from spilling out. In a brief synopsis of the box, the design is solely made for providing an easy access to small contents like straws in fast food chain or candies in a retail store.
