BACKGROUND OF THE INVENTION1. Field of the Invention
The subject invention relates to a stackable carrier system for products, such as food which is supplied to customers of carry out restaurants or purchased in convenience stores, and more particularly to, a carrier system wherein individual carriers can be stacked, interconnected and transported as a unit.
2. Background of the Related Art
A long standing problem encountered by businesses, such as carry out restaurants, is the ability to package and distribute large quantities of food to customers who carry the food to a distant site for consumption. It is difficult for a customer to carry much more than a few food packages, bags or trays, if only the hands are available for use in carrying the food.
Food carriers are used when more substantial quantities of food must be carried. However, because the carriers must be relatively low in cost, they usually are relatively flimsy and are easily deformed to cause the food to spill from the carrier. Moreover, the amount of food a customer can carry is still limited to the number of carriers a customer can handle.
It is therefore desirable to provide a robust carrier system wherein individual carriers can be stacked, interconnected and transported as a unit and thus enable a customer to more easily carry large quantities of items, such as carry out food. Moreover, it would be advantageous to provide a carrier system in which the carriers can be flat shipped.
SUMMARY OF THE INVENTIONThe present disclosure is directed to a stackable carrier system for items, such as but not limited to, food that includes, inter alia, first and second carrier bodies. The first carrier body defines an interior storage cavity and has opposed end walls and a first pair of opposed cover flaps which extend from respective end walls. Each of the opposed cover flaps define an interlock tab. The second carrier body also defines an interior storage cavity and has opposed end walls which define a reception slot therein. Wherein the interlock tabs are adapted and configured to interlock with the reception slots when the second carrier body is placed on top of the first carrier body. It is envisioned that in certain embodiments, the second carrier body also includes a first pair of opposed cover flaps which extend from respective end walls.
In a preferred embodiment of the stackable carrier system disclosed herein, each carrier body further includes a bottom wall and opposing side walls, the end walls and side walls each extending upwardly from a perimeter of the bottom wall to define the interior storage cavity. Moreover, each carrier body can include a second pair of opposed cover flaps which each extend upwardly from a top edge of respective side walls, each cover flap including a handle section and is adapted for covering at least a portion of the interior cavity of the carrier body.
It is envision that each of the first pair of cover flaps can further include an elongated slit which is adapted for receiving the handle sections formed of the second pair of cover flaps and securely close the carrier. Sill further, each of the first pair of cover flaps can include a fold line which enables the height of the flap to be reduced
In certain constructions, the carriers are formed using a single blank of material. In such constructions the bottom wall can be formed by securing a plurality of lower flaps in overlapping, face-contacting relationship.
Preferably, a sculpted cut line is used to create each of the reception slots formed in the end walls. Moreover, a sculpted cut line can be used to create each of the interlock tabs formed in the first pair of cover flaps.
The present disclosure is further directed to a stackable carrier that includes, among other elements, a carrier body that has a bottom wall and opposing end walls and side walls extending upwardly from the perimeter of the bottom wall to define a interior cavity. Each end wall has a reception slot defined therein.
The carrier further includes a first pair of opposed cover flaps that each extend from a top edge of respective end walls. Each cover flap defines an interlock tab. It is envisioned that each interlock tab is adapted to be received within and interlock with a corresponding reception slot associated with a second carrier body when the second carrier is placed on top the first carrier body. Moreover, each of the first pair of cover flaps can include a fold line which enables the height of the flap to be reduced.
It is envisioned that the stackable carrier can further include a second pair of opposed cover flaps that each extend upwardly from a top edge of respective side walls. Each cover flap includes a handle section and is adapted for covering at least a portion of the interior cavity of the carrier body. Preferably, the first pair of cover flaps further includes an elongated slit which is adapted for receiving the handle sections formed of the second pair of cover flaps and securely close the carrier.
It is contemplated that each bottom wall can be formed by securing a plurality of lower flaps in overlapping, face-contacting relationship.
In certain embodiments of the present invention, a sculpted cut line can be used to create each of the reception slots formed in the end walls and a sculpted cut line can be used to create each of the interlock tabs formed in the first pair of cover flaps.
The present disclosure is further directed to a material blank for use in a stackable carrier system. The material blank can include, inter alia, first and second side panels and first and second end panel. Each side panel includes a wall section and a bottom flap and each end panel includes a wall section, a cover flap and a bottom flap. The wall section of each of the first and second end panels defines a reception slot and the cover flap of each of the first and second end panels defining an interlock tab. Wherein the four panels are connected to form the blank and the first and second end panels are positioned adjacent to at least one of the first and second side panels and not each other.
In certain constructions, the first and second side panels each further include a cover flap. Moreover, the cover flaps associated with the first and second side panels can each include a handle section. In such a construction it is preferred, but not required that the cover flaps associated with the first and second end panels includes an elongated slit which is adapted for receiving the handle sections associated with the cover flaps of the first and second side panels. It is envisioned that the cover flap of each of the first and second end panels can include a fold line which enables the height of the flap to be reduced.
It is envisioned that the stackable carrier system of the present disclosure is made using paperboard. Although, the invention has been described in the context of a paperboard carrier, in other embodiments of the invention it is envisaged that other suitable foldable sheet material may be used for forming the carrier (such as cardboard, plastics material and the like).
