Additionally, a method of using the subject carton is provided.

In some embodiments, the carton body and/or the hinged carton lid of the subject carton may include a tamper-evident feature that may be used to indicate a “secure” condition of the carton and wherein the tamper-evident feature may be, for example, a perforated tear line, a tear-away strip, and/or the like.

Referring now to FIGS. 1 through 15, show various views and embodiments of an example of the subject carton 100 that may have a hinged lid 130, webbed corners 118, and a solid carton bottom. The carton 100 may be a used, for example, as a disposable food carry-out (or take-out) carton that is openable and closable.

The carton 100 may include a carton body 110 and a hinged carton lid 130. The carton body 110 may further include a floor panel 112, two opposing side panels 114 (e.g., a front side panel 114a and a rear side panel 114b), and two opposing end panels 116. The ends of the side panels 114 and the end panels 116 may be coupled via webbed corners 118. The webbed corners 118 may be, for example, a webbed corner inside glue design, wherein the webbed corners 118 may be adhered to an interior surface of their adjacent end panel 116 or side panel 114 (as shown, for example, in FIG. 7). Alternatively, the webbed corners 118 may be, for example, a webbed corner outside glue design, wherein the webbed corners 118 may be adhered to an exterior surface of their adjacent end panel 116 or side panel 114 (as shown, for example, in FIG. 14). The webbed corners 118 may be secured, for example, via an adhesive, thermal bonding, or any other suitable technique or mechanism. Each of the end panels 116 may include an upper edge flap 120. Each of the upper edge flaps 120 may include a side receiving slot 122. Further, a front locking tab 124 may be provided at the top edge of the front side panel 114a.

The hinged carton lid 130 may be a substantially flat hinged carton lid. The hinged carton lid 130 may include a lid panel 132 that may be hingeably coupled to the top edge of the rear side panel 114b of the carton body 110 via a fold line 134. A front edge flap 136 may be provided at the front edge of the lid panel 132. The front edge flap 136 of the lid panel 132 may include a front edge receiving slot 138. Further, a side locking tab 140 may be provided at each opposing end of lid panel 132.

The front edge receiving slot 138 of the hinged carton lid 130 may be designed to receive and hold the front locking tab 124 of the carton body 110. The side receiving slots 122 of the carton body 110 may be designed to receive and hold the side locking tabs 140 of the hinged carton lid 130. Further, the rear side panel 114b may include one or more vent flaps 142 (as shown, for example, in FIGS. 3, 7, 9, 13, 15).

The carton body 110 and the hinged carton lid 130 of the carton 100 may be formed of any lightweight, rigid or semi-rigid material that is suitable for holding and/or transporting, for example, a quantity of food and that is also suitable for disposing of after use. For example, the carton 100 may be formed of corrugated cardboard, paper, paperboard, post-consumer paperboard (i.e., recycled materials), biodegradable materials (e.g., sugarcane and paper), polystyrene foam (e.g., Styrofoam), plastic, molded fiber, and the like.

In operation, a user may fold the hinged carton lid 130 to a closed position and tucks the front edge flap 136 of the lid panel 132 behind the front side panel 114a of the carton body 110. Then, the user may engage the front locking tab 124 of the carton body 110 with the front edge receiving slot 138 of the hinged carton lid 130. Then, the user may engage the side locking tabs 140 of the hinged carton lid 130 with the side receiving slots 122 of the carton body 110.

One benefit of the presently disclosed carton 100 is that the carton body 110 has a solid floor panel 112 and that the carton body 110 is formed using the webbed corners 118 to form a disposable food carry-out (or take-out) carton that is suitable for holding wet foods reliably for some useful period of time without leaking.

For example, to form the carton body 110, the webbed corners 118 may be folded inward. Then, glue or other adhesive may be applied inside the fold such that facing surfaces of the webbed corners 118 are adhered or otherwise bonded together. In another example, a heat-sealable coating may be applied to the surfaces inside the fold of the webbed corners 118. Then, for each webbed corner 118, once the facing surfaces of the webbed corner 118 are folded into contact with one another, heat may be applied to the folded area and causing the heat-sealable coating to bond the facing surfaces of the webbed corner 118 together. Once the facing surfaces of the webbed corners 118 are adhered or otherwise bonded together, the folded webbed corners 118 may then be folded over in contact with an inside surface of its adjacent end panel 116 or side panel 114 and adhered or otherwise bonded thereto. Glue or other adhesive may be used to adhere or otherwise bond folded webbed corners 118 to the inside surface its adjacent end panel 116 or side panel 114. In another example, a heat-sealable coating may be applied to all or select surfaces of the interior facing surface of the carton body 110, and once the webbed corner 118 are folded into contact with the inside surface its adjacent end panel 116 or side panel 114, heat may be applied to the area and causing the heat-sealable coating to bond the webbed corner 118 thereto.

In another embodiment, to form the carton body 110, the webbed corners 118 may be folded outward. Then, glue or other adhesive may be applied inside the fold such that facing surfaces of the webbed corners 118 are adhered or otherwise bonded together. In another example, a heat-sealable coating may be applied to the surfaces inside the fold of the webbed corners 118. Then, for each webbed corner 118, once the facing surfaces of the webbed corner 118 are folded into contact with one another, heat may be applied to the folded area and causing the heat-sealable coating to bond the facing surfaces of the webbed corner 118 together. Once the facing surfaces of the webbed corners 118 are adhered or otherwise bonded together, the folded webbed corners 118 may then be folded over in contact with an outside surface of its adjacent end panel 116 or side panel 114 and adhered or otherwise bonded thereto (for example as shown in FIGS. 14 an 15). Glue or other adhesive may be used to adhere or otherwise bond folded webbed corners 118 to the outside surface of its adjacent end panel 116 or side panel 114. In another example, a heat-sealable coating may be applied to all or select surfaces of the exterior facing surface of the carton body 110, and once the webbed corner 118 are folded into contact with the exterior surface of its adjacent end panel 116 or side panel 114, heat may be applied to the area and causing the heat-sealable coating to bond the webbed corner 118 thereto.

Another benefit of the presently disclosed carton 100 is that the substantially flat hinged carton lid 130 allows for easy stacking of multiple of the cartons 100.

Referring now to FIG. 16 is a flow diagram of an example of a method 200 of using the presently disclosed carton 100. The method 200 may include, but is not limited to, the following steps, and not necessarily in the following order.

At a step 210, the carton 100 is provided.

At a step 215, a user may fold the upper edge flaps 120 inward.

At a step 220, a user may fold the hinged carton lid 130 to the closed position and tuck the front edge flap 136 of the lid panel 132 into the front side panel 114a of the carton body 110.

At a step 225, the user may engage the front locking tab 124 of the carton body 110 with the front edge receiving slot 138 of the hinged carton lid 130.

At a step 230, the user may engage one or both of the side locking tabs 140 of the hinged carton lid 130 with one or more of the side receiving slots 122 of the upper edge flaps 120 of the carton body 110.

In other embodiments, the carton body 110 and/or the hinged carton lid 130 of the presently disclosed carton 100 may include a tamper-evident feature (not shown) that may be used to indicate a “secure” condition of the carton 100. For example, the tamper-evident feature may be a perforated tear line, a tear-away strip, and/or the like. In one example, when the perforated tear line or tear-away strip is fully intact, the carton 100 is in the “secure” condition. By contrast, when the perforated tear line or tear-away strip is shown to be compromised, the carton 100 is in a “tamper-evident” condition.
