Storage box with spring-loaded locking lid
View Patent ↗The present invention refers to a storage box with a lid that includes a top, a bottom, two axial levers, and two snap springs with springy arms and sliding protrusions. The levers are integrated within the top and the snap springs are integrated into the bottom. When the user applies horizontal force on the levers they force the top to move up and release the lid from the container.
1 . A storage box ( 10 ) comprising a container ( 20 ) designed to hold materials, a lid ( 30 ) designed to cover the container, and a seal ( 40 ) designed to provide a secure closure between the lid and the container;
wherein the lid ( 30 ) comprises: a top portion ( 31 ) and a bottom portion ( 32 ); a right axial lever ( 33 R) and a left axial lever ( 33 L), each including two horizontal protrusions ( 331 ); a front snap spring ( 34 F) and a back snap spring ( 34 B), each including two springy arms ( 341 ) and a sliding protrusion ( 342 );
wherein the axial levers ( 33 R, 33 L) are integrated within the top portion ( 31 ), and the top further comprises: two right recesses ( 311 R) accommodating the horizontal protrusions of the right lever; two left recesses ( 311 L) accommodating the horizontal protrusions of the left lever; an upper bridge ( 312 ) under which the two axial levers are positioned side by side; two upper openings ( 313 ) enabling access to the axial levers; two front steps ( 314 F) on which the arms of the front snap spring are positioned; and two rear steps ( 314 B) on which the arms of the back snap spring are positioned;
wherein the snap springs ( 34 F, 34 B) are integrated into the bottom portion ( 32 ), and the bottom further comprises: a base ( 321 ); a front mount (F 322 ) accommodating the sliding protrusion of the front snap spring ( 34 F); and a rear mount (B 322 ) accommodating the sliding protrusion of the back snap spring ( 34 B);
wherein the lid ( 30 ) is assembled by snapping the top portion ( 31 ), which already includes the axial levers, onto the bottom portion ( 32 ), which already includes the snap springs, in such a way that the spring arms ( 341 ) flex downward as they engage the steps ( 314 F, 314 B), then settle onto the steps, thereby securing the top and bottom together with a spring-loaded lock;
wherein the snap springs ( 34 F, 34 B) are positioned in the lid such that their sliding protrusions ( 342 ) are integrated into the bottom portion ( 32 ), while their springy arms ( 341 ) rest on the steps of the top portion ( 31 ), creating a spring-loaded locking mechanism;
wherein the axial levers ( 33 R, 33 L) are positioned in the lid between the upper bridge ( 312 ) of the top portion and the base ( 321 ) of the bottom portion, allowing them to: be in a diagonal position when no horizontal force is applied to the upper parts ( 332 ) of the levers, and move into a vertical position when a horizontal force is applied to the upper parts of the levers, causing them to shift closer together;
wherein the lid ( 30 ) is designed to be in a tight state when no horizontal force is applied to the axial levers ( 33 R, 33 L), as the snap springs ( 34 F, 34 B) press the top portion ( 31 ) against the bottom portion ( 32 ), thereby compressing the seal ( 40 ) against a peripheral wall ( 21 ) of the container ( 20 ) to ensure a secure and airtight closure;
wherein the lid ( 30 ) is designed to be in a release state when a horizontal force is applied to the axial levers ( 33 R, 33 L), overcoming the spring force of the snap springs ( 34 F, 34 B) and shifting the levers into a vertical position, thereby: (a) causing the lower parts ( 333 ) of the levers to slide along the base ( 321 ) of the bottom portion ( 32 ); (b) raising the top portion ( 31 ) relative to the bottom portion ( 32 ); and (c) releasing the compression of the seal ( 40 ) against the container's peripheral wall ( 21 ), allowing the lid ( 30 ) to be removed from the container ( 20 ).
