Abstract
A container is disclosed with two lids, the first or outer lid can be torn off and discarded after a product is received by a recipient, such as a customer. Alternatively, the outer lid may be left in place with the container then being used as a return shipper with the outer lid remaining as part of the returned container.
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 62/476,369, entitled DUAL LID SHIPPING CONTAINER, filed on Mar. 24, 2017, which is incorporated by reference herein.
- This disclosure relates to containers, and more desirably, to containers adapted for use in product shipping applications, such as in internet order fulfillment or mail order shipping.
- A container is disclosed with two lids, the first or outer lid can be torn off and discarded after a product is received by a recipient, such as a customer. Alternatively, the outer lid may be left in place with the container then being used as a return shipper with the outer lid remaining as part of the returned container.
- This results in the elimination of a need for a master or outer shipping container within which a product containing container is positioned for shipping. That is, the container design of this disclosure eliminates a need to place one box inside a separate outer or master shipping box for the purpose of shipping. Outer shipping boxes often are oversized in that they are bigger than an internal product containing container positioned inside the outer box. This results in inefficiencies, due, for example to wasted truck or other transport shipping space occupied by oversized outer containers.
- This design reduces freight costs and a vendor's carbon footprint arising from the elimination of the weight and energy utilized in transporting a product in two boxes as well as the costs of producing materials for an entire second or outer box. Because a outer box is eliminated, the disclosed container design reduces labor and packing material costs in that additional packing materials (e.g., kraft paper, void filler, air pillows, Styrofoam peanuts, etc.) are not needed to cushion the space between an outer and an inner box; thereby making the design more environmentally friendly and cost effective to use.
- It is also desirable to provide a shipping container with improved crush resistance.
- In accordance with one embodiment, a container can comprise a bottom panel having an upper surface; first and second opposed wall panels and third and fourth opposed wall panels; the first, second, third and fourth wall panels each extending upwardly from the bottom panel and each having a respective upper edge. The height of these wall panels can be the same. A container in accordance with this embodiment, comprises a first lid having first and second opposed side edges and first and second opposed end edges, the first side edge of the of the first lid being foldably coupled to the upper edge of the first wall panel. The container also comprises a second lid having third and fourth opposed side edges and third and fourth opposed end edges, the third side edge of the second lid being foldably coupled to the upper edge of the second wall panel. The first lid can be foldable about the upper edge of the first wall panel to a closed position overlaying the bottom panel. In addition, the second lid can be foldable about the upper edge of the second wall panel to a closed position overlaying the first lid and the bottom panel. Desirably the first and second lids each extend from the side wall to which it is coupled substantially to the other side wall so that each encloses the container volume defined by the bottom panel and walls. In the assembled or erected container, a first end flap is foldably coupled the first end edge of the first lid and extends downwardly from the first end edge of the first lid. Also, a second end flap is foldably coupled to the second end edge of the first lid and extends downwardly from the second end edge of the first lid. The first and second end flaps are desirably sized such that, in the first lid closed position, the first and second end flaps, and desirably the lower edges of the first and second end flaps, engage the upper surface of the bottom panel. Also, in the assembled or erected container, a third end flap is foldably coupled the third end edge of the second lid and extends downwardly from the third end edge of the second lid. Also, a fourth end flap is foldably coupled to the fourth end edge of the second lid and extends downwardly from the fourth end edge of the second lid. The third and fourth end flaps are desirably sized such that, in the second lid closed position, the third and fourth end flaps, and desirably the lower edges of the third and fourth end flaps, engage the upper surface of the bottom panel

In addition, the container can comprise a second interior end panel wall section having upper and lower side edges, the upper side edge of the second interior end panel wall section being foldably coupled to and extending downwardly from the upper edge of the fourth wall panel. The lower side edge of the second interior end panel wall section is desirably spaced from the upper surface of the bottom panel section by a second gap. These gaps can vary in height from the bottom panel. Desirably, the gaps are each at least one-fourth of the distance between the upper surface of the bottom panel and the upper edge of the associated wall panel or the height of the associated wall panel. In a more specific example, the gaps are from one-fourth to seven-eighths of this distance or height.
