[0025] This application provides a polyethylene container suitable for airdrop.

[0026] like Figures 1 to 3 As shown, a polyethylene container suitable for airdrop includes a barrel 1 and a tail fin assembly 2 connected in sequence. One end of the barrel 1 is connected to the tail fin assembly 2, and the other end of the barrel 1 serves as the front end of the barrel 1. The tail fin assembly 2 includes a connecting post 3 connected to the barrel 1 and tail fin blades 4. The connecting post 3 is provided with multiple tail fin blades 4. The front end of the barrel 1 is conical, and the center of the end face of the front end of the barrel 1 is a plane. The multiple tail fin blades 4 are evenly distributed circumferentially, and each tail fin blade 4 includes a main body portion 41 and an extension portion. 42. The main body 41 is connected to the connecting post 3. The extension 42 is located on the main body 41 at the end away from the barrel 1. The inner side of the extension 42 gradually slopes outward from the end near the main body 41 to the end away from the main body 41, forming an inclined abutment edge 43. The inclination of the inclined abutment edge 43 matches the conical part at the front end of the barrel 1. When two adjacent polyethylene blow-molded containers are stacked, the front end of the barrel 1 of one polyethylene blow-molded container is located between multiple tail fins 4 of another polyethylene blow-molded container.

[0027] The airdrop-compatible polyethylene container of this application can be used as a fire extinguishing bomb. In this application, the front end of the barrel 1 has a flat surface. When a single airdrop-compatible polyethylene container is placed, the front end of the barrel 1 faces downwards, with the flat surface abutting against the placement platform, allowing the single container to be placed stably and vertically. When multiple airdrop-compatible polyethylene containers are needed for storage or transportation, they are stacked vertically, with the front end of the barrel 1 of each container facing downwards. The front end of the upper container's barrel 1 is located within the concave space formed by multiple tail fins 4 of the lower container, thus achieving vertical stacking of multiple containers. In this embodiment, the barrel 1 and tail fin assembly 2 are separate components. The barrel 1 is formed by blow molding, and the tail fin assembly 2 is formed by injection molding. Finally, the connecting column 3 and the barrel 1 are connected by threads.

[0028] In this embodiment, the tapered portion at the front end of the barrel 1 gradually increases in size from the plane at the front end of the barrel 1 to the outer side of the middle part of the barrel 1 in an arc shape.

[0029] The outer wall of the conical section at the front end of the barrel 1 is provided with a groove 11. The number of grooves 11 and tail fins 4 are arranged in a one-to-one correspondence. When two adjacent containers are stacked, the tail fins 4 are partially located in the grooves 11. The length direction of the grooves 11 extends along the conical sidewall at the front end of the barrel 1. When multiple containers are stacked, the tail fins 4 are located in the grooves 11, which further improves stability and restricts the circumferential deflection of adjacent containers. By fixing the bottom container circumferentially, and with the cooperation of the grooves 11 and tail fins 4, the containers in the same vertical column are circumferentially limited.

[0030] The groove 11 consists of an opening structure, a middle structure, and a bottom structure, arranged sequentially from the opening to the bottom. The two side walls of the middle structure of the groove 11 are press-fitted with the tail fin 4. The press-fit between the middle structure of the groove 11 and the tail fin 4 improves the stability when multiple containers are stacked.

[0031] The opening structure is flared, and the sidewall of the groove 11 gradually increases from the side closest to the central structure to the opening side. The flared design of the groove 11 can improve the efficiency of the tail fin 4 inserting into the groove 11.

[0032] Furthermore, the bottom structure of the groove is arc-shaped in cross-section perpendicular to the length of the groove 11. The design of the groove 11 extending parallel to the airflow and having an arc-shaped bottom reduces vortex generation, compensates for the influence of the front end face of the barrel 1 on the container's aerodynamic performance, and improves the container's aerodynamic performance. In one embodiment, the groove 11 and the tail fin 4 are staggered on the same container, with the centers of the groove 11 and two adjacent tail fins 4 aligned, further improving the container's aerodynamic performance.

[0033] An iron sheet is embedded in the bottom of the groove 11, and a magnet is provided on the inclined abutment edge 43 of the extension portion 42 of the tail fin 4. The iron sheet and magnet provide tactile guidance when stacking containers and improve the stability of the fit between the front end of the barrel 1 and the tail fin 4.

[0034] In this application, the design of the magnet and the iron sheet fit together with the interference fit of the groove 11 and the tail fin 4 can coexist in the design of the container, or the two designs can be used as independent structural designs.

[0035] Multiple magnetic blocks are embedded at intervals on the inclined abutment edge 43, and the magnetic blocks are located inside the extension portion 42 or flush with the surface of the extension portion 42.

[0036] In this embodiment, the end face of the connecting post 3 away from the barrel 1 is provided with a receiving groove, and a pull ring 5 is provided away from the receiving groove. The pull ring 5 is rotatably mounted on the bottom of the receiving groove. The rotation axis of the pull ring 5 is perpendicular to the axis of the pull ring 5 and parallel to the circumferential surface of the pull ring 5. The pull ring 5 rotates and flips along the rotation axis. When multiple containers are stacked together, the pull ring 5 flips into the receiving groove. Moreover, when multiple containers are stacked together, the top surface of the connecting post 3 and the front plane of the barrel 1 are spaced apart.

[0037] In one embodiment, multiple spaced recessed grooves 6 can be provided on the side wall of the barrel 1, allowing personnel to easily reach their hands into the recessed grooves 6 to retrieve the container.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
