Application May 21, 1941, Serial No. 395,343

' 1 Claim. zoo-44) My invention relates to aboxofflbrous sheet It is among the objects of ,my invention to provide a box adapted to permit ready insertion and removal of an article, such as a cake.

Another object is to provide a box having an outwardly foldable wall to which a cover is hinged, so that the cover and wall may fold out flat and whereby the cover may be telescoped over the box body when the wall is upright.

Another object is to' provide a box having an opening lying partially in a. top wall and partially in a side wall, so that the interior of the box may be viewed both in plan and elevation through the same opening, thereby materially improving the display. I

The invention possesses other objects and features of advantage, some of which. with the foregoing, will be set forth in the following description of my invention. It is to be understood that I do not limit myself to this disclosure of species of my invention, as I may adopt variant embodiments thereof within the scope of the claim.

Referring to the drawing:

Figure 1 is a perspective view showing the box closed; and

Figure 2 is a similar view of the box opened out wide.

Figure 3 is a perspective view of a modified box construction.

In terms of broad inclusion, my improved box comprises a body, and a cover hinged to an outwardly foldable wall of the body. This permits the cover to be folded out into the plane of the bottom in the wide open position. My box also has a window opening lying partially in one wall and partially in another wall, and the opening is covered with a sheet of transparent material, whereby the interior of the box may be viewed in both plan and elevation.

In greater detail, and referring to the drawing, my box comprises a body having a bottom' wall 2, and side walls or panels including end walls 3, front wall 4 and back wall 6. These terms are used purely for purposes of identification; it being understood any side may be considered the front. The cover comprises a top wall 1, and side walls or panels including end walls 8 and a front wall 9, the top 1 being hinged to body wall 6. End flaps II are also preferably provided on wall 6.

Back wall 6 is outwardly foldable, as shown in Figure 2, thus allowing this wall together with the attached cover to fold out flat. The remainmaterial, and more particularly to a cake box.

ing body walls 3 and 4, and the cover walls I andl, normally remain erect and are so held "by suitable connections at the corners. For example, locking tongues l2 engaging slits I3 may be provided, whereby the side walls may be disconnected and all folded flat for shipment. It is understood however that any other suitable corner construction may be used. Instead of disconnectable means, a permanently connected corner construction may be employed, preferably creased and foldable to permit collapsing the side walls flat for shipment.

The box is formed from a mans of suitable I article, such as a cake, may be readily inserted or removed from the box since the elongated tray permits sliding the cake endwlse and gives ample room for lifting or lowering it. This freedom of movement is particularly important in packaging frosted cakes because the soft and often sticky'fondants used for frostings make them difiicult to handle in the narrow confines of an ordinary cake box.

After inserting the cake on bottom 2, the wall 8 is erected and ,the cover telescoped over the body section. In this closing operation end flaps II are preferably interposed between body walls 8 and'cover walls'8, as shown in Figure 1. This interengaging of flaps ll between the telescoped walls forms' a tight corner and holds the flaps so that they cannot swing inwardly to interfere with the cake or mar its frosting.

'Another important feature of my invention is the provision of a window opening l4 lying partially in top wall I of the cover and partially in the back side wall 6 of the body. Disposed in two different planes, the window allows viewing the interior of the box in both plan and elevation through the same opening. This window arrangement materially improves the display over tamination, opening I4 is closed by sheet Id of transparent material adhesively united to the walls along the inner edges of the opening as illustrated in Figure 2. Since this sheet folds along the hinge line between walls 8 and 1, it is or a flexible material, such as Cellophane. Thus, in the wide open box position, sheet l6 lies flat and in the same plane as walls 2, 6 and I; while in the closed box position, the transparent sheet lies in two different planes. The width or the opening is reduced at the crease line along which the topl is hinged to the wall 8, so as to provide extensions projecting into the opening from opposite sides along the crease line. as shown in the drawing, thereby preventing objectionable weakening of the hinge joint, and reentorcing the flexible sheet along the hinge line. The improved window construction is particularly adapted to a cake box of the character described, but it is understood that it may be used in other box constructions where it is desired to improve the display.

The advantage of carrying opening ll over the hinge connection is that there are no overlapping parts at wall 6 to interfere with the window. In

event the opening is arranged in another of the walls, say cover wall 9, then a suitable cut-out or opening I1 is provided in the corresponding body wall 4, as shown in Figure 3. This construction is adaptable for any box having a. separate telescoping cover.

I claim:

A box comprising a bottom section, a cover section provided with a main panel and a wall panel hingedly connected to the main panel along a crease line upon which the wall panel is movable between collapsed and extended positions, the main panel and wall panel having an opening extending over a major portion of the area of both panels, extensions upon said panels projecting into the opening from opposite edges thereof along the crease line for elongating the hinge joints connecting said panels at the sides of the opening, and a sheet of transparent flexible material covering the opening and having cover and wall portions bendable along a line coinciding with the crease line of the panels.
