Venting device for a disposable food container

Abstract

A venting device and method for the retention of food temperature and texture is disclosed. The venting device of the present invention is inserted through the top, outside surface of a food container sufficiently to allow the device to puncture the surface of the container and allow venting of the steam and moisture created from the hot food within the takeout food container.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(7) Preferred embodiments of the present invention and their advantages may be understood by referring to FIGS. 1-5, wherein like reference numerals refer to like elements. Although the present invention is described and illustrated in the context of hot food containers, it is to be understood that the disclosure of the present invention is not limited to this embodiment but is equally applicable to containers in general wherein venting is advantageous.

(8) Referring to FIG. 1, the venting device 100 is illustrated and may be used with any variety of hot food containers. The venting device 100 of the present invention may be constructed as a unitary device from any type of plastic that has heat resistant properties such as thermoplastics including but not limited to nylon, acrylic, polypropylene, polystyrene, and polyvinyl chloride. The present invention may also be constructed of wood or steel. The pointed tip 110 of the venting device 100 is inserted through the top, outside surface of a food container sufficiently to allow the conical blades 120 to puncture the surface of the container to allow venting of steam and moisture. In an embodiment, in order to properly vent steam and moisture, the present invention includes at least four conical blades 120. Preferably, the present invention includes at least six conical blades 120. More preferably, the present invention includes at least eight conical blades as shown in FIG. 2. In some embodiments, the conical blades 120 alternate in length as shown in FIGS. 1 and 2.

(9) A flat, solid surface 130 of the venting device 100 provides a platform that protrudes from the top, outside surface of the food container sufficiently to allow stacking of multiple food containers. In this respect, the venting device 100 prevents stacked food containers from impacting the lid of the food container beneath and protecting the food therein from damage. In addition, in a stacked configuration, the flat, solid surface 130 permits the continued venting of steam and moisture for each stacked food container.

(10) To facilitate use of the venting device 100 in a variety of hot food containers, the device may be constructed in a range of lengths. In some embodiments, the venting device 100 has a length between 0.5 inch to 3 inches; or 0.75 inch to 2.75 inches; or 1.0 inch to 2.5 inches; or 1.5 inches to 2.0 inches. The venting device 100 may be constructed in a range of widths. In some embodiments, the venting device 100 has a width between 0.5 inch and 2 inches; or 1 inch and 1.75 inches; or 1.25 inches and 1.5 inches.

(11) The flat, solid surface 130 may also be of any shape. In a preferred embodiment, the flat, solid surface 130 is circular but in alternative embodiments, the flat, solid surface 130 may be, by way of non-limiting examples, rectangular or square. The shape of the flat, solid surface 130, however, will not affect the conical shape of the blades 120. The advantageous conical shape and taper of the blades 120 provides a venting device 100 easily inserted through more structurally sound food containers such as corrugated cardboard and paperboard.

(12) In an alternative embodiment (not shown), the venting device 100 has along the periphery of the conical blades 120 a protrusion (not shown). The protrusion acts as a stop to prevent the venting device 100 from being inserted too far into the interior of the food container. In addition, the protrusion maintains the integrity of the venting device 100 when in a stacked configuration. In other words, the protrusion prevents the venting device 100 from proceeding further into the food container than desired or through the bottom thereof when added weight from stacked food containers is applied. The precise location of the protrusion will be dictated by 1) the type of food container; 2) the distance required for the flat, solid surface 130 to extend from the outside, top surface of a food container; and 3) the height of the interior cavity of the food container. These factors will likewise dictate the overall length of the venting device 100. Advantageously, the venting device 100 is lightweight, inexpensive device capable of mass production to fit a variety of takeout food containers.

(13) Referring to FIG. 2, a top isometric view of the venting device 100 is illustrated. FIG. 2 shows the alternating conical blades 120 of a preferred embodiment of the present invention.

(14) Referring to FIG. 3 is an alternative embodiment of the present invention. The alternative embodiment of FIG. 3 includes legs 140 originating from the flat, solid surface 130 and forming a conical structure that terminates at the pointed tip 110. In this embodiment, the legs 140 create a hollow cavity within the interior of the legs 140. The hollow cavity permits venting of steam and moisture from the food container. In this embodiment, the present invention includes at least four legs 140. Preferably, the present invention includes at least six legs 140. The legs 140 may be flat, curved, or round.

(15) The venting device 100 of FIG. 3 may also include along the periphery of the legs 140 a protrusion (not shown). The protrusion acts as a stop to prevent the venting device 100 from being inserted too far into the interior of the food container. In addition, the protrusion maintains the integrity of the venting device 100 when in a stacked configuration.

(16) Because the venting device 100 is positioned through the outside, top surface of a takeout food container, the steam and moisture are vented to the outside thereby minimizing the condensation on the interior of the container. Accordingly, the hot food contained in the food container retains its temperature, crispness and texture.

(17) Referring now to FIGS. 4 and 5 is illustrated an alternative embodiment that does not include the solid surface 130 of FIG. 1. In this alternative embodiment, the conical blades are flattened on their ends opposite the pointed tip 110. This flattened surface provides a platform that protrudes from the top, outside surface of the food container sufficiently to allow stacking of multiple food containers.

(18) In an alternative embodiment, the present invention contemplates a venting device that facilitates the creation of venting apertures in the surface of a food container. In this alternative embodiment, the venting device includes an ergonomic handle and at least four conical protrusions to allow the venting device to easily puncture the surface of a food container. The four apertures created in the food container by the venting device allow venting of steam and moisture. Advantageously, the venting device easily penetrates a variety of materials making up food containers common in the industry including, but not limited to, thermoplastics, corrugated cardboard and paperboard. The venting device of the alternative embodiment may be constructed as a unitary device from any type of thermoplastics including but not limited to nylon, acrylic, polypropylene, polystyrene, and polyvinyl chloride. The alternative embodiment may also be constructed of wood or steel.

(19) Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

(20) Moreover, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. Reference will now be made in detail to the preferred embodiments of the invention.
