FOOD PACKAGE Charles Doering, Chicago, Ill. Application December 23, 1938, Serial N6. 247,434

3 Claims.

This invention relates to packages and more particularly to edible food confining cartons prepared from heavy sheet material, although certain features thereof may be employed with equal advantage for other purposes.

It contemplates more especially the provision of a comparatively inexpensive and improved package for edible substances such as cheese that is poured therein preparatory to inserting a liner serving as a hermetic seal therefor.

It is customary to package cheesein five and two and one-half pound loaves by pouring cheese as the final step of its pasteurizing' into a wooden box lined with tinfoil that serves as a hermetic seal therefor. These wooden boxes are expensive, present substantial bulk, and render it difficult to remove the contents which is dispensed over the counter in small sliced quantities. The wooden box serves as a mold for the cheese which is filled therewith and the tinfoil liner is overlapped to preclude contamination with the walls of the box as well as to serve as a hermitic seal therefor. I

One object of the present invention is to provide an edible improved food confining paper carton that is comparatively inexpensive in construction and more satisfactory for its purpose.

Another object is to provide a heavy paper carton having features of construction enabling the fractional ejection of the contents without requiring the complete removal thereof to dispense such to the purchasing public.

Still another object is to provide an improved and less expensive paper carton for comparatively large quantities of cheese and. similar edible substances for fractional dispensing without removal of the entire contents except as ordered.

A further object is to provide an improved paper carton having content ejecting expedients to render the contents readily available witl-out requiring the entire mass to be removed therefrom preparatory to serving each order.

A still further object is to provide an improved edible substance container or carton witha detachably associated slicing device to enable the fractional dispensing of sliced units thereof' without requiring the entire mass to be removed for each order.

Still a further object is to provide an improved container that renders the contents readily accessible for dispensing in sliced units without requiring the entire mass to be removed therefrom.

Other objects and advantages will appear from 55 the following description of an illustrative embodiment of the present invention.

Figure 10 is a sectional View in elevation of a cc untry roll shaped carton of the type shown in Figure 3, it being similar to the sectional view shown in Figure 4 except that the latter is of Holland roll rather than country roll shape.

The structure selected for illustration comprises an elongated and substantially cylindrical body enclosure l0 prepared from sheet material such as cardboard to represent a Holland, country roll, or rectangular cross-section depending upon the dictates of commercial practice and the choice of the purchasers. The body In is, in this instance, open at both ends II and H to permit a liner such as tinfoil or other suitable material l3 to cover the interior walls thereof preparatory to covering end enclosures l4 and I5 thereof. The end enclosures l4 and I5 are stamped or otherwise shaped from heavy cardboard or other paper sheet material to telescopically engage the open ends H and I! of the carton body Hi to define an enclosed carton after the contents l6 has been poured or otherwise incorporated therein.

In order to render the contents l6 available for slicing portions from the open end I2 thereof, a disc I! corresponding in cross-section with the interior of the carton body I8 is inserted adjacent the end II in parallel relation with the end enclosure l4. To this end, the end enclosure I4 is provided with an axial aperture I8 therein to enable the introduction of the attendants finger or a suitable rod I9 to engage the disc I1 and serve to eject the contents I6 from the end l2 after the closure I5 has been removed therefrom. This affords access to the end portion of the contents I6 for sliced removal per order without requiring the entire mass I6 to be removed each time.

The contents such as cheese'or other edible substances I6 is preferably incorporated in the interior of the lined carton III while it is still hot or warm. Thereupon, the tinfoil is overlapped at the end I2 to hermetically seal it from the atmosphere. After the enclosure I5 has been attached to the body ID, a rectangular sheet of material 20 suitably imprinted to serve as a label may be pasted over the carton ID with its enclosures I4 and I5 to retain them in assembled position against accidental removal. This completes the packaging of the edible contents I8 to allow it to breathe through the aperture I8 in the enclosure I4 during the cooling thereoi after being incorporated into the container III.

The breathing function constitutes the ejection of air and gases and moisture from the edible substances such as cheese I6 during its cooling operation which conforms with the interior of the container I and its liner I3 to adapt itself to the reformed contents IS.

The usual knife 2I can be utilized to slice the mass I6 (Figure 1) in the customary manner as it is ejected by means of applying force through the rod I9 or projecting the finger of the attendant through the aperture I8 in the end enclosure I4. In the modified embodiment shown in Figure 3, the container body is divided into two equisized segments I8 and I0", rather than a single open end body with an additional thickness of material 22 adhesively or otherwise attached to the interior of the portion I 0' as at 23. An overlap whose exterior size conforms with the interior of the container body portion I0 is te'escopically displaced thereover in frictional engagement therewith.

With the section bodies I0 and I8", there is the equivalent of a single body portion such as shown in Figure 1. This can be lined. in the usual manner with tinfoil I3 preparatory to pouring the contents such as cheese I6 therein. Correspondin nd enclosures I4 and I5 tolescopically engage the open ends II and I2 of the container body sections I0I0. The'end enclosure I4 is provided with an axial aperture I8 to enable the incorporation of the attendants finger or a rod I9 to eject the contents l6 from the body section I0" and then from the body section I0 after its size is diminished to a point that enables the removal of the body section I8" so that the enclosur I5 can be directly app ied to the body section ID.

This arrangement precludes the neceisity of utilizing another rod I9 in that access to the cheese contents I6 is effected without any appreciable displacement of the ejecting disc It. 7

This is possible owing to the fact that the body section III may be totally dispensed with a.tsr one-half of the cheese contents I6 has been sliced therefrom. A label can be adhesively III applied over the container sections l0-I0 to- 75 gether with the end enclosures I4--I5 to preclude accidental separation of the component elements of the carton. It will be apparent, therefore, that av very inexpensive and more effective carton can be provided for large loaves of cheese and other edible substances usually dispensed in fractional units by slicing portions from the mass I8 or I6. The vendor need not remove the entire contents "5 or I6 from the carton I8 or III and as a result less time is entailed in the dispensing of the contents I6 or I6 and such is not exposed to the atmosphere to the extent otherwise necessary.

In order to render the contents I6 or I6 readily dispensable in uniform slices of predetermined thickness, a slicing attachment consisting of a metallic body 24 may be placed over the container end I2I2 in place of the end enclosure l5 or I5. This end, the slicing attachment body 24 is shaped to correspond with the end enclosure I5 or I5 depending upon whether such are to be country roll (Figure 2), Holland roll (Figure 4) in shape. The attaching frame or body 24 is shaped to correspond therewith, and it is preferably though not essentially molded or otherwise shaped from aluminum or other metallic substances to present an interior opening 25 that corresponds with the exterior diameter of the container body I6, I8 or ill.

To this end, the interior of the slicing frame 24 is stopped as at 26 so that the latter opening will conform in size with and receive the overlap 23 should it be desired to apply a slicing attachment body 24 to the container section II). In order to effect the sliced removal of the contents I6 or I6, a blade knife frame 21 corresponding in size and shape with the body 24 is attached thereto by means of threaded studs 28, in this instance four, which are properly placed along the side edges thereof to present an elongated slit 29 in the top wall 38 that communicates with a corresponding groove 3| in the side walls 32 and 33 of the frame 21. The top slit 29 of the side groove 3I serves to accommodate a slicing blade 34 which is vertically displaceable between the attachment body 24 and its confronting frame 21.

Any suitable manipulatingmeans such as an enlarged rounded flange 35 may be attached to the top edge of the blade 34 to enable its vertical manipulation in severing the mass l6 or l6 in uniform slices. The thickness of the slices may be varied depending upon the dictates of each purchaser and such may be pre-measured by the stop 36 constituting an offset flange formed on a blade member 31. The blade member 31 has an elongated slot 38 provided therein to receive a threadedstud 39 which engages a lug 48 provided on the side wall of the slicing attaching body 24. The blade member with its offset flange 36 will, therefore, be adjustable to determine the desired thickness of the unit to-be sliced from the mass I6 as it is ejected to confront and engage the stop 36.

It will be apparent, therefore, that a simple, inexpensive and effective slicing attachment has been provided for a container of the type described herein. In order to hold the blade 34 in its initial position preparatory to slicing, an aperture M is provided along a longitudinal median line of the blade 34 proximate to the lower severing edge 42 thereof. The aperture 4| cooperates with a spring impelled 'detent that is urged in the path thereof by means of a spring 7 v in the slot 29 would entail some time and care which would not be very desirable from the vendors standpoint.

It should be noted that the inside wall of the container ID or III is coated or impregnated with a paraffin wax film or other suitable wax filler to fill up the minute voids therein and render the container more effective as a hermetic seal of the contents it or it. Further, this parafiin or other filler film serves to preclude sticking of the tinfoil H to the wall of the container III or III Then, too, the inside surface of the tinfoil l3 or other suitable liner is preferably provided with a resinous film or other suitable coating so that the overlapping portions of the liner I3 will be self-adhering as the hot cheese IE or IE is poured in the container ill or ID. The elevated temperature of the contents I 6 or it as it is poured into the container will cause the coating on the liner l 3 to fill the minute voids therein so as to further reinforce the hermetic seal of the contents [6 or it. The coating will soften upon the contact of the hot cheese IE or ii thereon and furnish a desirable seal therefor.

With the teachings of the invention described herein, it will be apparent that a more sanitary and less expensive package has been provided whereon suitable inexpensive label can be adhered so that the distributors thereof may resort to private labels without any appreciable expense. A container of this kind is less expensive and much lighter than the usual wood containers heretofore employed for a similar purpose and, in consequence thereof, the handling and transportation expense is much less. Paper containers are usually devoid of undesirable odors usually found in containers of wood construction and in every respect the teachings of the pres- Various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the features of the invention or any advantages thereof, and nothing herein shall be construed as limitations upon the invention, its structural concept or embodiment as to the whole or any part thereof except as defined in the appended claims.
