A firecracker package includes a packaging box body, a packaging component, and a buffering material. The packaging component is provided in the packaging box body and is used for firecracker packaging, and the buffering material is provided between the packaging box body and the packaging component and is used for absorbing the impact and preventing explosion. The firecrackers have a good impact absorption and explosion-proof effect during transportation or consumption, which avoids the explosion caused by extrusion, and improves the safety performance. Moreover, the sealing effect is promoted, the waterproof and moisture resistance performance is stronger, the expiry date is prolonged, and the environmental pollution is avoided.

Stackable ammunition containers include movable lids defining recesses within which feet of another ammunition container may be inserted. The feet and recesses may have specific dimensions and positions to balance between retention of the feet within the recesses to provide structural stability when stacked and ease of unstacking.

Shock resistant mounting structures for fuze systems. The shock resistant mounting structures may comprise: a shock resistant fuze cap and a shock resistant collar. The shock resistant fuze cap may comprise a circular cap housing and a plurality of cripple studs disposed within the circular cap housing. The circular cap housing may be adapted to engage an upper portion of a fuze and may be adapted to snugly fit within a fuze well. The shock resistant collar may comprise a ring-shaped housing and one or more cripple studs radially disposed within the ring-shaped housing. The ring-shaped housing may have a center opening adapted to engage a fuze body. When installed, the shock resistant fuze cap and shock resistant collar may be disposed within the fuze well and may minimize, prevent, or divert shock loading energy from entering a fuze.
