nnzrn K. PATTON, or PHILA- CANDY PACKAGE.

Application filed June 10, 1922. Serial No. 567,347.

To all whom it may concern:

Be it known that we, JOHN G. PATTON', a citizen of the United States, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, and ALBERT D. Fnnwro r, a citizen of the United States, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, have invented a new and useful Candy Package, of which the fol.- lowing is a specification.

Our present invention comprehends a novel construction of a package or container which has been especially designed for the packing of candy under a vacuum.

In the packaging of candy such as, for example, fudge, it has not been practicable up to the present time to pack it in such a way that it will not deteriorate.

Fudge contains a considerable amount of moisture when it is first manufactured and after a few weeks it dries out and is not a salable product. In attempting to pack candy in a can or tin under the vacuum processfit has been found that. if the sun 5 shines on the can or tin the fudge which is in close proximity to the wall of the tin becomes aifected and the same holds true if the can is left in close proximity to any source of heat.

In accordance with our present invention,

the fudge is packed within the can in such a manner that there is an insulating space entirely around the candy. Other novel features of construction and advantage will hereinafter more fully appear in the detailed description and the appended claims.

For the purpose of illustrating our invention, we have shown in the accompanying drawing a typical embodiment thereof which is at present preferred by us, since this embodiment will be found in practice to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that our invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. 1

Figure 1 represents, in perspective, a candy package] embodying our invention, with one end removed for the sake of clearness of illustration;

Figure 2 represents a section on line 22 of Figure 1.

Figure 3 represents a section on line 3-3 of Figure 2.

Figure 4 represents, in perspective and in detached position, an end spacing member employed. Figure 5 represents a top plan view of a section of an article container.

Figure 6 represents a top plan view of another formof section of article container which may be employed.

Similar numerals of referenceindicate corresponding'p'arts. i Referring to the drawing,

' 1' designates a can or container which may have any desired contour but which, as illustrated, is cylindrical and has the ends 2 which are crimp'ed to the juxtaposed body portions of they can. of the can is secured in sealed position to the body portion of the can and after the material to be packed has been placed within the can, the other end is secured in position within a vacuum chamber'so that the goods will be packed under a vacuum. Goods as heretofore packed under the vacuum process have simply been placed within a single walled can and the open ends sealed and closed while a vacuum is being applied to the interior of the can. In these prior methods many articles such as. for example, fudge, if packed in this way, could not be kept in a satisfactory condition. In the bottom of the can we place an end spacing member 3 preferably formed of metal and having opposite sides deflected, as at 4, in order to space the body portion from the juxtaposed end wall of the can.

In order to'stifl'en the body portion cuts are made in it and the tongues 5 are bent outwardly so as to have the same function as the deflected sides or flanges 4. The body portion of an end spacing member is provided with a multiplicity of perforations 6.

The end member 7 at the opposite end which serves 'as a spacing member, see Figure 2,

is constructed in a similarmannerso that the detailed. explanation of one will sufiice for both. 8 designates the inner container for the material which is to be packed which has. as illustrated, a polygonal contour and which can be formed from one or more sheets of sheet material which preferably would be meta-l:

In practice, one end \Ve have shown a rectangular shaped in-.

ner container '8 in which the metal at the corners is deflected upon itself to form the spacing'projections 9 and at'the free ends of the sheet-the material is deflected out wardly' to form "the spacing projection 10, see Figure 3. The side walls are perforated, as indicated at 11. In this manner air chambers 12 are formed around the side walls of the inner container, ianlair chamber 13 being formed at the bottom, and an air Chamber Hat the top, so that the material plied. v.The top .of the can is then secured in sealed condition with respect to the body portion of the can'within a vacuum so that a vacuum :is present between the. inner and outer walls of .thepackage. It will be seen that inlthis manner if the can: is placed in close proximity to a source of heat or if the sun should shine upon it, the heat must be transmitted through the insulating space -b.cfore it can have any effect upon the candy or-other material packed within thecan.

The outercan 1 can be opened in any desired manner and in practice is preferably provided withthe tongue 16 so that a strip will .be torn from the can between the ,parallel lines 17, see Figure 1.

In so far as we areaware, we. are the first in the art to devise a practical manner of packing fudge so that it will be kept in sub stantially the samecondition as when itis first packed for a considerable period of time. 4 V

- 1. 1 Figures 1, 2 and 3, we "have shown the inner container as being formed from an integral piece of sheet material. It will be apparent-that instead of making it out of one piece it can. be made in sections as illustrated in Figure 5 or Figure 6. In Figure 5, the-construction is the same as in Figure 3 except that a perforated sheet metal strip 18 vhas opposite edge portions constructed asat 19 so that when these are assembled in the outer container the construction and function will be the same as that shown in Figures 1 to 3 inclusive. In some cases arising in practice it is not necessary to deflect the opposite edge portions as at 19 and a rectilinear perforated sheet 20 as shown in Figure 6.1nay be employed to form the article container when a "plurality of these are. assembled within theouter container,

' We havepreferred to illustratethe outer container as having a polygonally shaped ,may seem desirable in practice.

be employed so long as an insulating space is provided between the inner perforate-d container and the outer container. It will of course be apparent that one ofthe end spacing members can be formed integral with or united with a section of the inner container or a wall of the inner container as In will now be apparent that we have de vised a novel and usefultconstruction of a candy package which embodies the features of advantage enumerated as desirablein the statement o-fthe invention and the abovede scription, and while we have, initherpresent instance, shown and described a preferred embodiment thereof which Wlll give in practice satisfactory and reliableresults, it is to be understood that this embodiment is susceptible of modification in various :particulars without departing from the spirit or scope of the invention or sacrificing any of its, advantages. l I

Having thus described our invention, What wexclaim as new and desire tozsecure by Letters Patent, is: V r

1 An article package,comprising an outer container, having sealed ends :and a vacuum therein, an inner article container formed: from a single sheet of :metal deflected to provide a plurality of corner centering members, adapted to contact, with therinner surface of, the outer container wall toform air insulatingspaces around the iinnerlarticle container, the walls of said inner arrl'icle container having perforations therein,

and upper and. lower perforated end members positioned at the top and bottom of said outer container and having respectively extended to form lateral spacing projections which abut against the inner surface ofthe wall of the outer casing to centersaidinner polygonal casing, there being a vacuum chamber around said inner polygonal-casing,

perforated top and bottom end plates arranged between each sealed end of said outer casing and the ends of said inner cas-v ing and abutting against the ends of said innercasing to form top and bottom vacuum chambers isolated .from said annular vacuum chamber, and outer and central outwardly deflected flanges for said top-and bottom-end 7 plates which abut against the sealedends of said outer casing. l a

3. A container of the character stated, comprising an outer casing having sealed ends, and a vacuum therein, an inner polygonal rigid casing, whose corners are extended to form upper and lower laterally opposed projections, which abut against the wall of the outer casing to center said inner polygonal casing, there being an annular vacuum chamber around said polygonal casing, perforated top and bottom end plates arranged between each sealed end of the outer casing and in abutting relation with said inner casing to form end vacuum chambers isolated from said annular vacuum chamber, said inner casing having means of 15 communication with both the annular and end vacuum chambers, and spacing devices for said top and bottom end plates, contact ing with the top and bottom ends of said outer casing, said corner projections con- 20 tacting with said top and bottom end plates.
