Abstract

A system and a method for automatically packaging item(s) are disclosed, as well as associated packages. The method includes generally four steps. First, an outer tray containing one or more item(s) is received. Second, an inner tray is placed in the outer tray over the one or more item(s), and the inner tray includes a plurality of preformed columnar compartments. Third, the inner tray and the outer tray are sealed to form at least a partial vacuum between an exterior surface of the inner tray and an interior surface of the outer tray. The item(s) are firmly secured in the at least partial vacuum such that the item(s) will not shift within the package during shipment. Fourth, a cover is placed over the inner tray to close the plurality of preformed columnar compartments to thereby form a plurality of air compartments, which collectively protect the item(s) from external impact.

First claim

What is claimed is:

1. A package, comprising;
an outer tray configured to contain an item therein;
an inner tray configured to be received within the outer tray over the item contained in the outer tray, the inner tray including a plurality of preformed columnar compartments that are deformable relative to one of surfaces of the outer tray in response to contacting the item, wherein the inner tray is sealed with the outer tray to form at least a partial vacuum between an exterior surface of the inner tray and an interior surface of the outer tray to vacuum seal the item between the outer and inner trays; and
a cover placed over the inner tray to seal the plurality of preformed columnar compartments to thereby form a plurality of pressurized air compartments that enclose the item with at least one of the pressurized air compartments pressed against the item.

2. The package of claim 1 , wherein a first pressure in the at least partial vacuum is approximately 600 millibar to 700 millibar, and a second pressure in the plurality of air compartments is approximately 1,013 millibar.

3. The package of claim 1 , wherein the outer tray and the cover are formed of opaque material, and the inner tray is formed of transparent material.

4. The package of claim 1 , wherein the inner tray is formed of polypropylene (PP) material, and a thickness of the inner tray is approximately 100 μm.

5. The package of claim 4 , wherein the outer tray is formed of polyethylene terephthalate (PET) material and a thickness of the outer tray is approximately 450 μm.

6. The package of claim 1 , wherein the inner tray and the outer tray are sealed with adhesive to form an adhesion between the inner tray and the outer tray.

7. The package of claim 6 , wherein the adhesion has a torque value of approximately 1,000 gf-15 mm.

8. The package of claim 6 , wherein the adhesion is formed along rims of the inner tray and the outer tray.

9. The package of claim 8 , wherein each of the inner tray and the outer tray has a respective projecting rim, and the adhesive is applied between the respective projecting rims.

10. The package of claim 1 , wherein the plurality of preformed columnar compartments include at least one compartment having a circular cross-section, at least one compartment having an elliptical cross-section, and at least one compartment having a beam cross-section.

11. The package of claim 1 , wherein the inner tray is at least partially deformed within the outer tray upon contact with at least one of the outer tray or the item contained therein.

12. A system for automatically packaging items in a package, comprising:
an outer tray on a support, the outer tray containing one or more items;
a first station configured to place an inner tray within the outer tray over the one or more items contained in the outer tray, the inner tray including a plurality of preformed columnar compartments that are deformable relative to one of surfaces of the outer tray in response to contacting the one or more items, and to seal the inner tray and the outer tray to form at least a partial vacuum between an exterior surface of the inner tray and an interior surface of the outer tray to vacuum seal the one or more items between the outer and inner trays; and
a second station configured to place a cover over the inner tray to seal the plurality of preformed columnar compartments to thereby form a plurality of pressurized air compartments that enclose the one or more items with at least one of the pressurized air compartments pressed against the one or more items.

13. The system of claim 12 , wherein the support comprises a conveyor.

14. The system of claim 13 , wherein the first station is positioned upstream of the second station along the conveyor, and the system further including a central controller configured to control operation of the conveyor, the first station, and the second station.

15. The system of claim 12 , wherein the first station includes a sealer configured to form the at least partial vacuum having a pressure of approximately 600 millibar to 700 millibar.

16. The system of claim 12 , wherein the first station is configured to seal the inner tray and the outer tray with adhesive to form an adhesion between the inner tray and the outer tray.

17. The system of claim 12 , wherein the first station and the second station form a single station.

18. A method of automatically packaging items in a package, comprising:
(i) receiving an outer tray containing one or more items;
(ii) placing an inner tray in the outer tray over the one or more items contained in the outer tray, the inner tray including a plurality of preformed columnar compartments that are deformable relative to one of surfaces of the outer tray in response to contacting the one or more items;
(iii) sealing the inner tray and the outer tray to form at least a partial vacuum between an exterior surface of the inner tray and an interior surface of the outer tray to vacuum seal the one or more items between the outer and inner trays; and
(iv) placing a cover over the inner tray to seal the plurality of preformed columnar compartments to thereby form a plurality of pressurized air compartments that enclose the item with at least one of the pressurized air compartments pressed against the one or more items.

19. The method of claim 18 , wherein step (iii) comprises forming the at least partial vacuum having a pressure of approximately 600 millibar to 700 millibar.

20. The method of claim 18 , wherein step (iii) comprises sealing the inner tray and the outer tray with adhesive to form an adhesion between the inner tray and the outer tray.
