Abstract

A reclosable food tray is disclosed comprising a receptacle portion and two pairs of opposing closure flaps. The receptacle portion has substantially trapezoidal volume defined by a rectangular shaped bottom panel and two substantially upstanding pair of opposing side panels. The opposing side panels defined four pairs of adjacent panels which are hingedly connected in liquid-sealed manner by four folded gussets secured by three pairs of notch cuts. The notch cut is a curved and hook-like cut serves as interlocking mechanism to hold the food tray together. The pair of notch cuts can also be disconnected from each other to open the panel(s). The notch cut enable the food tray shipping in blank and erected by end user, also eliminates metal wire and adhesives that are commonly used by prior arts. A carrying strap purposely designed for carrying one or multiple food tray is a component of the invention.

Claims

1. A reclosable food tray erected from a single unitary blank having an interior and exterior surface, a substantially square gross geometry and curved looped hook-like notch cuts as fastening and interlocking mechanisms which allows the food tray, without assistance of adhesive or metal wire, to be shipped as a blank, erected and shaped by an end user and to be opened and reclosed from both the top and sides of the food tray;

said food tray comprising;

a fully constructed receptacle portion having access openings from the top or the side permitting introduction of food into said receptacle portion, said receptacle portion having a volumetric geometry defined by a rectangular shaped bottom panel, a first substantially upstanding pair of opposing side panels and a second substantially upstanding pair of opposing side panels;

said opposing side panels defining four pairs of adjacent side panels with each pair of adjacent side panels being hingedly connected by one of four folded gussets, each said gusset being unitary with one said pair of adjacent side panels, each said gusset including said notched cuts and short cut lines which allows said gusset to be secured and interlocked with an opposing one of the four folded gussets, each said side panel being disposed at a first obtuse angle measured from the bottom panel so that said volumetric capacity facilitates nesting of the receptacle portion of said food tray with a receptacle portion of another reclosable food tray;

each of said curved looped hook-like notch cuts comprising an inner loop line, an outer loop line, a tip point where the outer and inner loop lines curve and merge together and optional teeth-like rough edges along the inner loop line wherein said inner loop lines serve the purpose of providing more security to secure the food tray, said notch cuts being capable of hooking and unhooking into each other permitting the food tray to reclose and reopen;

a pair of opposing closure flaps each extending from one of said first pair of opposing side panels and each including one of said notch cuts, a second pair of opposing closure flaps each extending from one of said second pair of opposing side panels and each closure flaps each including one of said notch cuts, said first pair of closure flaps adapted to cooperatively interlock and close off a portion of the top access opening and said second pair of closure flaps adapted to overlap a portion of the first closure flaps, interlock together and close off the top access opening.

2. The reclosable food tray of claim 1, wherein each said folded gusset is suitably dimensioned so that said receptacle portion is capable of retaining liquid or semi-solid consumables without leakage through said receptacle portion.

3. The closable food tray of claim 2, wherein said two substantially upstanding pair of opposing side panels comprise a first side panel disposed opposite a second side panel, a third side panel disposed opposite a fourth side panel, with said first side panel being adjacent said third and said fourth side panels and said second side panel being adjacent said third and fourth side panels to form a volume having trapezoidal dimensions.

4. The reclosable food tray of claim 1, wherein said blank comprises paperboard material which is substantially resistant to microwave and other heat radiation.

5. The reclosable food tray of claim 1, wherein said first pair of opposing closure flaps are hingedly connected to said respective opposing side panel salong respective top fold lines, and each folded gusset has an upper edge which extends substantially along one of said respective top fold lines.

6. The reclosable food tray of claim 5, wherein said first and second pair of opposing side panels are hingedly connected to said bottom panel along respective bottom fold lines, and each said side panel has left and right side fold lines, each of which are disposed at a second obtuse angle with respect to adjacent bottom fold lines.

7. The reclosable food tray of claim 6, wherein said blank comprises paperboard material which is substantially resistant to microwave and other heat radiation.

8. The reclosable food tray of claim 1, which further comprises a folded partition for insertion into said receptacle portion to divide said receptacle portion into two or more separate food storage compartments.

9. A carrying strap for carrying a plurality of food trays, each food tray as set forth in claim 1, said carrying strap being formed from a single unitary blank comprising:

a rectangular shaped bottom panel;

two isosceles trapezoidal upstanding sides each connected to an opposing side of said rectangular shaped bottom panel;

two long narrow substantially rectangular shaped extended strap portions each connected to one of said upstanding sides along an upper edge of the upstanding side, said strap portions each including line cuts at one end allowing said strap portions to engage each other to form a carrying strap, said strap portions further including fish scale cuts strategically punched along the strap portion to engage and retain said trays within the carrying strap during use.
