With the development of the cannabis market, child proof tins are moving towards airtight and plastic-free designs. Currently, airtight child proof tins on the market are mainly achieved in three ways: 1. Child proof tins with blister or injection-molded plastic inner trays; 2. Child proof tins with silicone inner trays; 3. All-metal child lock structures. Compared to the ubiquitous round airtight child proof tins, rectangular airtight tins offer a wider variety of child proof variations. Today, we’ll recommend several all-metal, plastic-free, airtight square child proof tins.
100x60x20mm rectangular hinged child proof metal box. This sealing structure mainly consists of three parts: an outer rolled-up lid and bottom child proof metal box, an inner rolled-up metal support, and a foam gasket or silicone sheet. This metal box provides a stable child proof and a 100% seal, meeting the standard of no leakage even when filled with water and shaken. Current series of sealed child proof metal boxes are available in sizes of 80x60x20mm, 100x60x20mm, and 120x60x20mm.
This is a 105x65x20mm rectangular child-proof tin box with a hinge. The sealing structure consists of three parts: an inner-rolled lid that snaps onto the tin’s constricted opening to form a hidden child proof; an inner-rolled metal support; and a silicone gasket. The stability of this tin box was improved in 2022 by adding finger positions to increase the child proof mechanism’s tolerance. Its seal is leak-proof even when filled with water, but slight leakage may occur with vigorous shaking. Currently, its sealing performance is second only to the 100x60x20mm child-proof lock tin box. Other sizes in this series of child-proof lock tin boxes are 94x40x20mm and 77x34x18mm.
This is a 75x55x22mm rectangular, hinged, child-proof lock sealed tin box. The sealing structure consists of three parts: an outer-wound child proof lock tin box, an all-metal inner tray, and a silicone or foam gasket. Compared to the 100x60x20mm child-proof lock sealed tin box, the biggest difference is its three-piece structure. This design perfectly matches the needs of pre-rolls storage, making the tin box compact and portable with a stable child proof lock and high sealing performance. It is a brand-new plastic-free, all-metal child-lock sealed tin box. However, according to water sealing tests, this tin box will still leak slightly, but its odor-proof sealing standard is sufficient. The 75x55x22mm child-proof lock sealed tin box is also available with an inner-wound design. This all-metal design is aesthetically pleasing, with a stable and concealed child proof lock, making it a high-end tin box; however, its high cost means it is not yet in production. This all-metal, plastic-free child-proof lock sealed tin box design is suitable for the high-end market of major brands.
