Foldable container and foldable supporting frame thereof, and folding method
View Patent ↗A foldable container includes a foldable supporting frame, at least one operation switch arranged on the foldable supporting frame, and a container body supported on the foldable supporting frame. The operation switch is actuated through a pulling operation to move the foldable supporting frame between an unfolded mode and a folded mode. The container has an edge and an opening formed within the edge. At the unfolded mode, the opening is opened. At the folded mode, the opening is closed. The container body is automatically folded as the foldable supporting frame is moved from the unfolded mode to the folded mode. Via a folding method, the foldable supporting frame is folded to reduce an overall size for occupying less storage space when it is not in use.
1. A container assembly, comprising:
a container body comprising a bottom wall and a surrounding wall connected to said bottom wall, wherein said surrounding wall comprises an edge which comprises an edge sleeve and at least one fixing rib received in said edge sleeve; and
at least one top supporting arm, wherein each of said at least one top supporting arm comprises a rod body having a fixing cavity and a slot communicated to said fixing cavity, wherein said edge of said surrounding wall of said container body is placed in said fixing cavity through said slot and is retained in said fixing cavity, so as to mount said container body with said at least one top supporting arm;
wherein said edge sleeve of said surrounding wall has two mounting holes and two retaining channels, wherein each of said two mounting holes are respectively communicated to said two retaining channels, wherein said edge of said surrounding wall comprises two said fixing ribs, wherein said two fixing ribs are respectively inserted into said two retaining channels through said two mounting holes and are respectively retained in said two retaining channels.
2. The container assembly according to claim 1 , wherein said container assembly comprises two said top supporting arms, wherein said two fixing ribs are respectively received in said fixing cavities of said two top supporting arms.
3. The container assembly according to claim 2 , wherein each of said two fixing ribs is shaped and sized to couple with said fixing cavity of said corresponding top supporting arm for retaining each of said two fixing ribs within said fixing cavity of said corresponding top supporting arm.
4. The container assembly according to claim 2 , wherein said two top supporting arms define an opening of said container assembly.
5. The container assembly according to claim 2 , wherein said two top supporting arms are spacedly mounted to said edge of said surrounding wall of said container body to define a central foldable portion of said edge of said surrounding wall of said container body between said two top supporting arms, wherein said central foldable portion of said surrounding wall of said container body is folded when said two top supporting arms are folded.
6. The container assembly according to claim 5 , further comprising two folding assemblies, wherein said mounting ends of said two top supporting arms are respectively pivotally coupled to said two folding assemblies, wherein when said two top supporting arms are folded, said central foldable portion of said surrounding wall of said container body is folded.
7. The container assembly according to claim 6 , wherein each of said two folding assemblies has a mounting groove, where two said mounting ends of said two top supporting arms are respectively pivotally coupled at said mounting groove.
8. The container assembly according to claim 5 , wherein each of said two top supporting arms is constructed to have a U-shape.
9. The container assembly according to claim 2 , further comprising two folding assemblies, wherein said two top supporting arms are respectively pivotally coupled to said two folding assemblies.
10. The container assembly according to claim 2 , wherein said container body is a flexible body that is made of a flexible water-proof material selected from the group consisting of Polyethylene, Polyvinyl Chloride, Polypropylene and Thermoplastic Urethane, wherein each of said two top supporting arms is made of rigid material selected from the group consisting of wood, metal, metal alloy, and plastic.
11. The container assembly according to claim 2 , wherein said container body is made of Polyvinyl Chloride and each of said two top supporting arms is made of Aluminium.
12. The container assembly according to claim 2 , wherein each of said two top supporting arms is constructed to have a U-shape.
