Storage container with hinged lid
A plastic container comprises a container body having an opening to an interior of the container body; and a lid constructed and arranged for removably coupling to the container body The lid comprises a base portion covering a first region of the opening of the container body; a movable portion covering a second region of the opening of the container body in a closed position and exposing the opening to the interior of the container body in an open position; and a hinge arrangement between the base portion and the movable portion. The movable portion is constructed and arranged to rotate about an axis along which the hinge arrangement extends, and relative to the base portion. The base portion and the movable portion each extends at a predetermined height above the opening of the container body.
1. A plastic container, comprising:
a container body having an opening to an interior of the container body; and
a lid constructed and arranged for removably coupling to the container body, the lid comprising:
a base portion covering a first region of the opening of the container body;
a movable portion covering a second region of the opening of the container body in a closed position and exposing the opening to the interior of the container body in an open position; and
a hinge arrangement between the base portion and the movable portion, wherein the movable portion is constructed and arranged to rotate about an axis along which the hinge arrangement extends so that the movable portion in the closed position extends along a same longitudinal line as the base portion; and in an open position rotates about the hinge arrangement to be at an acute angle relative to the base portion, wherein the base portion and the movable portion each extends at a predetermined height above the opening of the container body to increase a volume of an interior of the container to be greater than the interior of the container body, wherein the hinge arrangement comprises:
a first plurality of ridges;
a second plurality of ridges parallel to the first plurality of ridges, the first and second plurality of ridges being supporting ribs extending along a width of the lid and allow for the movable portion to rotate about the hinge arrangement to be at an acute angle relative to the base portion;
a hinge unit parallel to the first and second plurality of ridges that connects the first plurality of ridges and the second plurality of ridges; and
a gap between an outer edge of the base portion and an outer edge of the movable portion in the closed position, wherein the gap begins at a distal end of the hinge unit and extends parallel to the first and second plurality of ridges to an outermost edge of the lid.
2. The plastic container of claim 1 , wherein the base portion, movable portion, and hinge arrangement are unitary and molded from a common source of plastic.
3. The plastic container of claim 2 , wherein the hinge unit extends along the width of the lid and is longer than the first and second plurality of ridges and has a thickness that it is less than that of the base portion and the movable portion.
4. The plastic container of claim 1 , further comprising at least one supporting element that extends from the base portion to apply a force to a periphery of the container body.
5. A plastic lid constructed and arranged for removably coupling to a container body, the plastic lid comprising:
a base portion covering a first region of the opening of the container body;
a movable portion covering a second region of the opening of the container body in a closed position and exposing the opening to the interior of the container body in an open position; and
a perimeter skirt constructed and arranged to form a seal with a rim of the container body, wherein the base portion and the movable portion each extends at a predetermined height above the opening of the container body to increase a volume of an interior of the container to be greater than the interior of the container body; and
a hinge arrangement between the base portion and the movable portion, wherein the movable portion is constructed and arranged to rotate about an axis along which the hinge arrangement extends so that the movable portion in the in closed position extends along a same longitudinal line as the base portion; and in an open position rotates about the hinge arrangement to be at an acute angle relative to the base portion, wherein the base portion and the movable portion each extends at a predetermined height above the opening of the container body to increase a volume of an interior of the container to be greater than the interior of the container body, wherein the hinge arrangement comprises:
a first plurality of ridges;
a second plurality of ridges parallel to the first plurality of ridges, the first and second plurality of ridges being supporting ribs extending along a width of the lid and allow for the movable portion to rotate about the hinge arrangement to be at an acute angle relative to the base portion;
a hinge unit parallel to the first and second plurality of ridges that connects the first plurality of ridges and the second plurality of ridges; and
a gap between an outer edge of the base portion and an outer edge of the movable portion in the closed position, wherein the gap begins at a distal end of the hinge unit and extends parallel to the first and second plurality of ridges to an outermost edge of the lid.
6. The plastic container of claim 1 , wherein the hinge unit has a thickness that is less than a thickness of the first plurality of ridges and the second plurality of ridges.
7. The plastic container of claim 1 , wherein the first plurality of ridges extends from the base portion and the second plurality of ridges extend from the movable portion, wherein the first plurality of ridges are stationary and the second plurality of ridges pivotably rotate relative to the stationary first plurality of ridges and about the axis along which the hinge unit extends.
8. The plastic container of claim 1 , further comprising a first locking clip coupled to an annular flange of the container body for engaging with a front region of the movable portion opposite the rear portion to which the hinge arrangement is coupled.
9. The plastic container of claim 8 , further comprising a second locking clip coupled to the annular flange of the container body for engaging with the base portion, wherein the first locking clip and the second locking clip are constructed and arranged as handles.
10. The plastic container of claim 1 , further comprising a pair of stabilizing bars extending from an underside of the first plurality of ridges and the second plurality of ridges, respectively.
11. The plastic container of claim 10 , further comprising a pair of tabs that extend vertically between the pair of stabilizing bars to contribute to a reinforcement of the hinge unit.
12. The plastic container of claim 10 , wherein the lid includes one or more supporting elements that extend in a vertical or orthogonal direction from a perimeter of the container body to prevent shear forces from being applied to the hinge unit.
