Packaging container
A packaging container includes a base, a cover including a resilient unit and defining a deformable slot at the resilient unit, and a positioning hinge member provided at the base and rotatably received at the deformable slot to pivotally couple the cover with the base so as to enable the cover being pivotally folded between an opened position and a closed position, wherein the positioning hinge member has a non-circular cross section and is arranged in such a manner that when the positioning hinge member is rotated within the deformable slot, the resilient unit generates a resilient restoring force to assist the cover being folded between the opened and closed positions.
1. A packaging container, comprising:
a base;
a cover comprising a resilient unit and defining a deformable slot at said resilient unit; and
a positioning hinge member provided at said base and rotatably received at said deformable slot to pivotally couple said cover with said base so as to enable said cover being pivotally folded between an opened position and a closed position, wherein said positioning hinge member has a non-circular cross section and is arranged in such a manner that when said positioning hinge member is rotated within said deformable slot, said resilient unit generates a resilient restoring force to assist said cover being folded between said opened and closed positions, wherein said positioning hinge member has a preloaded corner, a cornering point and a positioning corner that said positioning hinge member is rotated from said preloaded corner to said positioning corner through said cornering point in order to pivotally fold said cover from said closed position to said opened position.
2. The packaging container, as recited in claim 1 , wherein a threshold angle is defined between said base and said cover when said positioning hinge member is rotated at said cornering point, wherein when a folding angle between said base and said cover is smaller than said threshold angle, said resilient unit generates as resilient restoring force as a closing force to push said cover toward said base so as to close said packaging container, wherein when said folding angle between said base and said cover is larger than said threshold angle, said resilient unit generates as resilient restoring force as an opening force to push said cover away said base so as to open said packaging container.
3. The packaging container, as recited in claim 1 , wherein said positioning hinge member has a parallelogram shape.
4. The packaging container, as recited in claim 2 , wherein said positioning hinge member has a parallelogram shape.
5. The packaging container, as recited in claim 2 , wherein said deformable slot has a cross section matching with said cross section of said positioning member.
6. The packaging container, as recited in claim 4 , wherein said deformable slot has a cross section matching with said cross section of said positioning member.
7. The packaging container, as recited in claim 4 , wherein said deformable slot is an open slot adapted to self-deform to adjust a width thereof.
8. The packaging container, as recited in claim 6 , wherein said deformable slot is an open slot adapted to self-deform to adjust a width thereof.
9. The packaging container, as recited in claim 6 , wherein said cover has an upper clipping point and a lower clipping point defined at an upper inner wall and a lower inner wall of said deformable slot respectively for limiting a non-axially movement of said positioning hinge member.
10. The packaging container, as recited in claim 8 , wherein said cover has an upper clipping point and a lower clipping point defined at an upper inner wall and a lower inner wall of said deformable slot respectively for limiting a non-axially movement of said positioning hinge member.
11. The packaging container, as recited in claim 10 , wherein said positioning hinge member is slidably inserted to said base from a sidewall thereof.
12. The packaging container, as recited in claim 10 , wherein said positioning hinge member is slidably coupled to said base from a bottom thereof.
13. The packaging container, as recited in claim 10 , wherein said positioning hinge member is mold-injected to said base to form an integrated structure.
14. A packaging container, comprising:
a base;
a cover comprising a resilient unit and defining a deformable slot at said resilient unit; and
a positioning hinge member provided at said base and rotatably received at said deformable slot to pivotally couple said cover with said base so as to enable said cover being pivotally folded between an opened position and a closed position, wherein said positioning hinge member has a non-circular cross section and is arranged in such a manner that when said positioning hinge member is rotated within said deformable slot, said resilient unit generates a resilient restoring force to assist said cover being folded between said opened and closed positions, wherein said positioning hinge member is slidably coupled at said base.
