Description
- The present disclosure relates to a storage unit that can be made of two or more sheets using a coupling mechanism for coupling the two sheets together.
- Various storage units for office supplies, documents, magazines, papers, etc. have been provided. However, the storage space required for such storage units is usually large, and a large amount of office space is usually required to hold such units before use.
- Paper file boxes have been provided that are flat, and require less storage. However, paper file boxes are generally constructed by gluing four side boards and a bottom board together. Although the paper file boxes may avoid environmental problems, the structure strength thereof is insufficiently strong in the gluing areas, and are tedious and take a long time to construct. A further drawback of the conventional file boxes is that they are not foldable after gluing and thus occupy a considerable space after being built.
- Various molded storage containers are also provided that can break down and do not require storage space when unassembled. For example, as provided in U.S. Pat. No. 3,675,808, a shipping container formed from a mold is provided that has a flat rectangular bottom wall with four sidewalls hinged thereto by integral thin flexible hinge portions. Two of the sidewalls have slots adjacent their side edges and two of the other sidewalls have ears projecting from side edges for insertion into the slots. Another molded container is provided in U.S. Pat. No. 6,827,231, which provides a minivan box liner having a molded bottom plate and a continuous wall comprising a plurality of panels and a plurality of hinge portions therebetween for permitting bending of the continuous wall at the hinge portions at angles therebetween.

FIG. 4 shows astorage unit 400, which can be a magazine holder, constructed offirst sheet 100,second sheet 200 andthird sheet 300. Thepanel 100 can be folded downward alongscores 140 such thatpanels storage unit 400 as shown inFIG. 400 .Panel 120 can be the bottom surface of thestorage unit 400.Second sheet 200 can be the back wall of thestorage unit 400, andthird sheet 300 can be the front wall of thestorage unit 400.Male connection members second sheet 200 couple together withfemale connection members panel 130, respectively, andmale connection members second sheet 200 couple together withfemale connection members panel 110, respectively, as shown inFIG. 4 .Male connection members third sheet 300 couple together withfemale connection members panel 130, respectively, andmale connection members third sheet 300 couple together withfemale connection members panel 110, respectively. - The width w1 of the openings of the female connection members 160 a-160 e and 170 a-170 e can be approximately the same as or slightly larger than the width w2 of the
neck portion 280 of the male connection members 210 a-210 e and 220 a-220 e. The width w3 of the retainingportion 290 is even larger than the width w1 of the opening and the width w2 of theneck portion 280. Accordingly, the retainingportion 290 is first inserted into the openings of the female connection members, and a slight force is needed to push the retaining portions of the male connection members through the openings of the female connection members. Then, because the similarity of the widths w1 and w2, a tight coupling is formed between the male and female connection members. The lateral protrusions of the retaining portions of the male connection members extend beyond the width of the opening and face generally axially with respect to the opening. - Preferably, the male connection members and female connection members comprise a snap lock connection, such that once the retaining portion is pushed through the opening, a snap lock connection is made between the male and female connection members. Such a snap lock connection can be removable so that the
storage unit 400 can be broken down intoflat sheets portion 290 to release the male connection member from the opening of the female connection member, allowing a quick and easy disassembly of thestorage unit 400. -
FIG. 5 shows a broken side view offirst sheet 100.Second sheet 200 andthird sheet 300 can also have similar structure asfirst sheet 100 as will be described below. Thesheet 100 can be made of a foam material, and can have threelayers FIG. 5 . Thesheet 100 can be an extruded foam sheet, and can have a substantially uniform thickness. The foam material can be a polypropylene structural foam material. Polypropylene structural foam can be made of three layers of polypropylene material. Thetop layer 510 andbottom layer 530 can be for coloring and texture finishing, and themiddle layer 520 can be recycled polypropylene in foam form, which can highly reduce the density and sustainability of thesheet 100. - The
top layer 510 andbottom layer 530 can be mostly brand new polypropylene material, which can be between approximately 90-99% polypropylene, and even more preferably approximately 97% polypropylene, and the remaining can be polyethylene material. Thetop layer 510 andbottom layer 530 can be mainly for coloring and texture finishing (similar to rigid polypropylene flat material). The top 510 andbottom layer 530 can be the same color, or can have different colors. The densities for thetop layer 510 andbottom layer 530 can be between approximately 0.5-1.5 ton/m3, and preferably 0.85-0.95 ton/m3, and can even more preferably be approximately 0.91 ton/m3 (e.g., same as rigid polypropylene), and thethickness 501 of thetop layer 510 and thethickness 503 of thebottom layer 530 can be between 0.05-0.5 mm per layer, and preferably between 0-1-0.3 mm, and can even more preferably be approximately 0.2 mm per layer. - The
middle layer 520 can be approximately 90-99% recycled polypropylene and the remaining can be polyethylene material and foam agency. Themiddle layer 520 can preferably be approximately 95% recycled polypropylene, and 3% polyethylene and 2% foam agency. The foam agency is to provide the carbon dioxide (CO2) to make the polypropylene material of themiddle layer 520 foamed to a density of approximately between 0.5-0.9 ton/m3, and preferably between 0.6-0.75 ton/m3, and even more preferably approximately 0.68 ton/m3. Thethickness 502 of themiddle layer 520 can be approximately between 1-3 mm, and preferably between 1.2-2.6 mm. Thus, themiddle layer 520 can have a density less than the density of thetop layer 510 andbottom layer 530, and thethickness 502 of the middle layer can be greater than thethickness 501 of thetop layer 510 andthickness 503 of thebottom layer 530. - The polypropylene foam flat that comprises the sheets can be made by a three layer extrusion machine. Three extrusion screws extrude three kinds of material in three layers and stick together. After the polypropylene foam flat is extruded, a die-cutting machine can be used to cut the flat sheet to the requested shape required to construct a storage unit. The score lines can be made by a creasing line machine.
- There are plenty of benefits of using polypropylene foam to make the storage unit instead of injection molding. There can be provided a lower density of material so that the material is of a lighter weight. Two or more colors can be applied on the same piece of material. Different colors can be applied for different layers. There are less molding and tooling costs compared to injection molding. Further, the product can be flattened easily, which allows for easy shipping, storage, assembly and disassembly.
- One having ordinary skill in the art should appreciate that there are numerous shapes and sizes of the sheets that can be used, which will depend on the type of storage unit required. The storage unit can be a document tray, magazine file, trash bin, name card holder, accessory tray, office supplies holder, compact disc holder, storage box, or any other type of similar device required for storage of various articles.
- For example, as shown in
FIGS. 6-8 , the storage unit can also be a stacked document tray.FIGS. 6 a and 6 b showside members FIG. 6 a, a topright tray 610 and a bottomright tray 620 are shown havingfemale connection members 650 near edges or peripheries thereof.

The topright tray 610 is held by holdingmembers right tray 620. The holding members are secured to the topright tray 610 and the bottomright tray 620 byrivets 625. This allows the topright tray 610 and the bottomright tray 620 to pivot at an angle θ aboutrivets 625 with respect to each other, and allows the topright tray 610 to rest on the bottomright tray 620. It also allows the topright tray 610 to be held above bottomright tray 620, as shown inFIG. 6 a.FIG. 6 b shows a topleft tray 660 and a bottomleft tray 670 havingfemale connection members 650. Thefemale connection members 650 have openings and are similar to the female connection members described above. One or more female connection members may be used on each tray. The topleft tray 660 is held by holdingmembers left tray 670.
