6 Claims.

This invention relates to a package and to a novel carton for forming the package.

One object of the invention is tov provide a novel package for packaging one commodity within the body portion of the package and also a commodity in the form of a solid rectangular cake in a pocket forming part of one end closure and preferably the top closure of the carton.

Another object of the invention is to provide a novel construction of carton having a novel top closure providing a pocket for the reception of a rectangular cake and whose general construction is such as to enable the top closing operation, as well as the package filling operation, to be performed on existing packaging machinery with minimum modifications thereof.

With these general objects in view, and such others as may hereinafter appear, the invention consists in the package and carton hereinafter described and particularly defined in the claims at the end of this specification.

In the drawings illustrating the preferred embodiment of the invention, Fig. 1 is a plan view of the preferred form of carton blank; Fig. 2 is a detail in perspective illustrating the upper porticn of a carton formed from the blank shown in Fig. l preparatory to the formation of the top ck sure; Fig. 3 is a similar view illustrating the po;ition occupied by the various top flaps during the partial formation of the top closure, and Fig. 4 is a detail in perspective of the upper por- Hon of the complete package with a portion b!)k8i'l away.

In the packaging of certain commodities, partlcularly bird seed, it is desirable that the package, in addition to containing the comminuted bird seed, should also have provision for operatively supporting a solid rectangular bird biscuit, and the present carton and package aims to provide a construction of carton which lends itself to the packaging operations of filling the carton with the bird seed and closing and sealing the top thereof on existing packaging machinery with minimum modifications thereof, and whose construction is such as to enable a suitable rectangular pocket to be formed in the top closure of the carton for the reception of the solid cake of bird biscuit. The formation of the pocket may be readily accomplished by suitable mechanism embodied in the packaging machinery, as will be described.

Referring now to the drawings, Ill represents a carton blank which is slit and scored to provide the usual bottom flaps l2 and side seam panel ll. The upper portion of the carton blank is slit and horizontally scored to provide a pair of relatively wide side flaps l8, l8 and relatively narrow end flaps 2U, 22. The one end flap 20 is arranged to be of a substantially greater length than the length of the other end flap 22 and of the side flaps l6, l8 such difference in length corresponding to the heighth or thickness of the rectangular bird biscuit or similar solid article that it is desired to operatively support in the pocket to be formed in the top closure. The horizontal score line 24 for the bottom of the end flap 20 is connected by diagonally arranged score lines 25, 26 to the adjacent horizontal score lines of the side flaps I6, l8, as shown in Fig. 1, and the second narrow flap 22 is provided with a score line 21 which is spaced from the upper end thereof a distance corresponding to the thickness of the biscuit or cake to be received within the pocket.

In the construction of the carton from the carton blank, the body portion of the carton is folded into rectangular formation, the side seam l4 sealed to the opposed end panel, and then the bottom flaps closed and sealed in accordance with the usual practice. The rectangular-shaped carton in the condition ready for receiving the bird seed, or other loose material, is shown in Fig. 2, and lends itself to handling in the standard filling or weighing machines now on the market for handling standard cartons. After the loose material has been deposited in the package, the next step in the operation is to fold inwardly the end'fiap 22 the upper end thereof being folded on the score line 21 so that a tab portion 33 thereof extends downwardly, or substant ally perpendicular thereto, into the position shown in Fig. 3. The second end flap 20 is now folded inwardly about the score line 24, the two side Wings 28. 29 folding about the

vertical score line

30, 32 and also about the diagonal score lines 25, 26 so that the main body of the end fiao 20 assumes a horizontal position as shown in. Fig. 3 and forms, in effect, the bottom wall of the pocket, the

wings

28 and 29 then extending vertically upward from said bottom wall and para lel with the side panels of the carton and forming the s des of the pocket. The carton blank is slit on the lines 31, 38 so that the side panels l6, l8 are separated from the wings 28. 29 attached to the end flap 2!]. The downwardly extended tab 33 of the end flap 22 cooperateswith the flap 20 to form the end wall of the pocket, and when the side flap I8 is folded and adhesively secured to the first folded end flap 22, and the side flap I6 is folded and adhesively secured in overlapping relation to the side flap l8, the top closure for the package and the top wall of the pocket is thus completed with the provision of a pocket open at one end, rectangular in shape and of a size to permit the introduction therein of a rectangular cake of bird biscuit in the manner illustrated in Fig. 4. The projecting portion 40 of the cake after the latter has been introduced into the pocket serves, in effect, to complete the rectangular shape of the package thus facilitating the commercial handling and packaging of the complete package for shipment.

From the description thus far it will be observed that the only modification in existing packaging machinery required to handle the present carton resides in the provision of suitable mechanism in the top sealing machine for folding in the two

end flaps

20, 22 to form the bottom wall and one end wall of the pocket, and that otherwise the carton forming, filling and sealing operations may be performed with the existing mechanisms now employed for such purposes.

While the preferred embodiment of the invention has been herein illustrated and described, it

will be understood that the invention may be embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:

i. A carton comprising a body portion provided with wide side panels and relatively narrow end panels, said side panels being provided with a pair of relatively wide side flaps of less width than the width ofthe side panels. said side flaps being sealed together in overlapping, relation one of the narrower end flaps being provided with wings connecting it to the side panels and being folded inwardly under and in spaced substantially parallel relation with the folded down overlapping and adhesively sealed side flaps to provide a rectangular pocket, the remaining end flap being folded inwardly and adhesively secured to the under surface of the first folded down side flap, and forming a closure for one end of said pocket, whereby to form a pocket open at one end only for the reception of a substantially rectangular article.

2. A package comprising a carton as defined in claim 1, and a substantially rectangular article in the pocket of said carton.
