Abstract

A carton is provided having opposite side portions which project beyond the lower surface of carton. The lower surface is provided with apertures so that heat may pass through the apertures when the carton is placed in an oven or other heating chamber. A strip of film is secured to the lower surface and along an adjoining wall. The film normally closes the apertures, but is removable to expose the apertures.

Claims

1. A generally triangular carton for use in containing a wedgeshaped piece of pizza or the like including:

a generally triangular bottom panel having a base edge and converging side edges, a generally rectangular end wall hingedly connected to the base edge of said bottom panel and extending upwardly therefrom, a generally triangular top panel hingedly connected to the upper edge of said end wall, said top panel being substantially identical in size and shape to said bottom panel, and extending parallel to said bottom panel, inner side wall panels secured to the converging edges of said bottom panel and extending upwardly therefrom, outer side wall panels secured to the converging edges of said top panel and extending downwardly therefrom outwardly of said inner side wall panels, means securing said inner and outer side wall panels in face contact, corner flaps connecting the converging ends of side walls, and connecting the ends of said end wall to said side walls, said bottom panel having a series of spaced apertures therethrough, a strip of film secured to the under surface of said bottom panel and upwardly along said end wall panel, said strip closing said apertures, the strip of film being secured in a manner to be readily detachable to expose said apertures.

2. The structure of claim 1 and in which said outer side walls extend below the plane of said bottom panel to support said bottom panel in spaced relation to a surface upon which said carton is placed.

3. The structure of claim 1 and in which said end wall is defined by weakened lines of contact.

4. The structure of claim 1 and in which said end of said strip of film extends beyond the surface of said top panel.

5. The structure of claim 1 and in which said top panel includes a detachable area adjoining said base edge thereof, and including a pair of weakened lines of separation extending downwardly from the edges of said detachable area between which said film strip is secured.

6. A carton including:

a bottom panel, first side walls hinged to the edges of said bottom panel and extending upwardly therefrom, a top panel hingedly secured along one edge to one of said side walls and extending substantially parallel to said bottom panel, said top panel being substantially identical in size and shape to said bottom panel, second side walls hingedly secured to the remaining edges of said top panel and extending downwardly therefrom and secured in face contact with said first side walls, said bottom panel having a series of spaced apertures extending therethrough, a strip of film secured to the under surface of said bottom panel and extending upwardly outwardly of one of said side walls, said film closing said aperture and being secured in a manner to be readily detachable to expose said apertures.

7. The structure of claim 6 and in which said second side walls lie outwardly of said first side walls and extend below the plane of said bottom panel to support said bottom panel in spaced relation to a surface upon which said carton is placed.

8. The structure of claim 6 and in which said one side wall is defined by weakened lines of separation.

9. The structure of claim 6 and in which an end of said film extends above the surface of said top panel.

10. The structure of claim 6 and in which said top panel includes a detachable area adjoining said one side wall, and including a pair of weakened lines of separation extending downwardly from the edges of said detachable area in said one side wall between which said film strip is secured.
