FIG

PROTECTIVE HOOD FOR CARRY-OUT FOOD AND FOLDABLE BLANK THEREFOR BACKGROUND OF THE INVENTION This invention relates generally to an apparatus for covering prepared food, such as carry-out products of drive-in type restaurants and the like, which food is to be transported away from the location of its preparation prior to consumption thereof. In the carry-out food trade, which is highly competitive, there occurs from time to time shortcomings requiring change in packaging of the food to improve both quality in taste and appearance of the product to enhance the dining pleasure of the consumer. Frequently, carry-out food is found to be undesirably cold, crushed, soggy, dirty, and/or otherwise unattractive. More particularly, this invention relates to an apparatus for shielding prepared food from dust and dirt in the atmosphere. Moreover, it is an object of this invention to provide an enclosure for prepared carry-out food served on a platter, such as meat and vegetables, on a plate, such as a sandwich, or in a tray, such as French fried potatoes, onion rings, or the like.

It is also an object of this invention to prevent carryout food from becoming crushed.

It is further an object of this invention to provide means for retaining the heat of food which is prepared hot, and to prevent such food from becoming soggy, and to otherwise maintain the pleasing appearance of the food.

In the general practice of the carry-out food trade, in which sandwiches and hot food in platters are wrapped in metal foil or paper, there is a tendency for the food to become crushed. In the case of French fried potatoes and onion rings, which are packaged in paper bags closed or unclosed at the top, these fried foods tend to be unappetizing because of a tendency for the heat to be trapped and steam to be condensed, leaving the food soggy and less desirable to the consumer when the bags are closed. On the other hand, if the bags are open at the top, fried food will be cold and undesirable to the consumer.

SUMMARY oF THE INVENTION Briefly, in summary, the present invention provides a protective hood for covering prepared carry-out food to ensure optimum dining satisfaction commensurate with the skill of the preparer of such food and a blank for assembling such a hood. The hood takes the form of a generally vertically extending sleeve which is selectively foldable to a flat condition for shipment or storage and to an erect condition for stand-by or actual service. In erect condition, the hood has an open bottom and means for supporting and retaining a food container inserted into the hood. The means for supporting and retaining a food container within the hood may take any desired form, such as ledges or the like, though in the illustrated forms, holes are formed in the sleeve in which edge portions of a food container of suitable size may project in supported and retained condition. The hood according to the invention, of ne cessity, must have an overhead covering member. The covering member may be integrally formed with the sleeve in its entirety or a portion thereof, whereby a lid is provided which may be opened or closed, as desired. To enclose a food container within the sleeve of the hood, the container may be introduced into the sleeve through its open bottom or its top, depending upon various factors, such as shape of the food container, shape of the hood, and other criteria. A further advantage of the protective hood according to this invention resides in the fact that it is of tapered configuration so that a plurality of such hoods may be erected and nested upon each other in standby condition for rush-hour use.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in detail to the drawings, a preferred embodiment of the protective hood H according to the present invention is seen in FIGS. l-S. In the preferred embodiment hood H is in the form of a generally vertically extending sleeve 10 with front and rear walls or

sections

12 and 14, respectively, side walls or

sections

16 and 18, an overhead covering member 20. Extending from one side of side wall 16 and integral therewith along a common edge 11 is an adhesive section 22. Each of the walls or sections l2, l4, l6 and 18 are generally trapezoidal in shape and in preassembled condition, as seen in FIG. 3, are disposed in a series with wall 12 having a free edge 13. Hinge fold lines l5, l7, l9 and l I extend between and integrally connect adjacent pairs of walls 12 and l8, l8 and 14, 14 and 16, and wall 16 and adhesive section 22 adjacent thereto, respectively. A series of

holes

24, 26, 28 and 30 and a notch 32 are formed in adjacent portions of adhesive section 3 22, and

walls

16, 14, 18 and 12 at the

fold lines

11, 19, 17, 15 and free edge 13, respectively.

Overhead covering member is in the form of a lid which may be selectively opened or closed and is integrally hinged to wall 14 along fold line 21. Covering member 20 includes a tuck flap 34 integrally hinged thereto along line 36.

Side walls

16 and 18 are provided with

foldable side flaps

38 and 40 extending therefrom along

fold lines

42 and 44, respectively.

Side walls

16 and 18 also include

hinge lines

46 and 48 extending from top to bottom thereof, respectively, to facilitate folding of the hood 10 for shipment or storage condition. For the convenience of the consumer, a scored tear strip 50 is provided on adhesive section 22. The assembled sleeve 10 includes an open bottom 55 and an upper opening 56.

To facilitate assembly, adhesive section 22 is formed with a straight edge 52 which may be squared with edge 53 of wall 12 and hole 24 and notch 32 in superposed registered relationship after which section 22 is adhered to wall 12 to form sleeve 10, which may be stored or shipped in a folded flat condition as seen in FIG. 4.

When the hood H is to be put to use, it is erected from the folded condition of FIG. 4 to the erect condition of FIG. 2. As seen in FIG. 5,

walls

12 and 14 converge in the downward direction. While not shown, it is clear that

walls

16 and 18 also converge in the downward direction and thus facilitate a nested stacked relationship of erected hoods H for standby use. When it is desired to introduce a food container T, such as a tray, of suitable size into sleeve 10, the container or tray T is introduced at the top since the opening 56 is larger than opening 55. The sleeve 10 is particularly suitable for use with a container T which has a tapered configuration so that it may be lowered into the sleeve until corner edge portions of the tray T are received in

holes

24, 26, 28 and 20 and are supported and retained thereby in a wedge relationship. As seen in FIG. 5, the tray T is fully surrounded by sleeve 10 whereby the food contained therein is shielded from dirt and wind in the atmosphere and will not become crushed. Additionally, if the food in tray T is French fried potatoes, the holes 28 and will allow a slight amount of ventilation to thereby prevent condensation of moisture so that the potatoes will remain crisp instead of becoming soggy. When the food is to be eaten, access thereto may be had by pulling tear strip 50 after which sleeve 10 unwinds and exposes the food in container T. The open bottom 55, in addition to allowing entry of food, effects a saving in material.

ALTERNATIVE EMBODIMENTS A second embodiment of the present invention is presented in FIGS. 6-10, wherein a protective hood H is provided in the form of a sleeve 110. The sleeve 1 10 is generally in the shape of a truncated cone diverging in the downward direction, as seen in FIG. 8. Because the sleeve 110 diverges in the downward direction, it has a bottom opening 155 of larger dimension than would be at the top of the sleeve 110. Consequently, a food container P of suitable size is introduced into sleeve 110 through bottom opening 155. Protective hood H is particularly suitable for enclosing platter type food containers P and includes a plurality of spaced apart holes 124 and 126.

Holes

124 and 126 are in the form of horizontally elongated slots and include a plurality of

semi-circular extensions
