What is Auto lock bottom box?
The auto lock bottom box is a type of paper packaging box specifically designed for efficient packaging. Its most prominent feature is the pre-adhesive design at the bottom, which allows it to automatically lock into shape without the need for additional tools when unfolded. This type of box is also known as a “crash-lock bottom box” or an “automatic closing box” and is widely popular because it can be assembled within a few seconds. It is particularly suitable for scenarios that require rapid packaging, such as in the retail, e-commerce, cosmetics, food, and toy industries. According to industry standards, this kind of box can generally safely carry items weighing up to 1 kilogram, providing an ideal packaging solution for small and medium-sized products.
Structural principle of auto lock bottom box
The structural core of auto lock bottom box lies in the automatic locking mechanism at the bottom. Here is a detailed description of its working principle:
Pre-glued design: During the manufacturing process, the folding pieces at the bottom of the box are pre-glued and folded at two key points. These folding pieces will snap into each other when the box is unfolded to form a flat and solid bottom.
Automatic locking: When the user presses on the sides of the box, the pre-glued folding pieces will automatically slide into the preset position and lock into a stable plane. This mechanism is often called a “two-point gluing system” to ensure that the bottom will not loosen easily.
Top design: The top of the box is usually designed with a tuck flap, which is easy to open and close while providing additional closure security.
| Structural Features | Description |
| Bottom Design | Pre-adhesive folding flaps that automatically lock when unfolded |
| Adhesive Points | Usually two adhesive points to ensure stability |
| Top Closure | Tuck flap or other closing mechanisms |
| Load-Bearing Capacity | Up to about 1 kilogram, suitable for small and medium-sized products |
| Assembly Method | Manual or automated, formed by pressing |
