G.G.PENROSE PACKING CARTON April 1, 1930.

Filed Nov 28, 1927 Patented Apr. 1, 1930 PATENT FFI E GEOB GE G. PENBOSE, OF CHICAGO, ILLINOIS racxme CARTON Application fled Iovember 28, 1827. Serial No. 238,072.

My invention relates to Cartons or containers of the class in which articles such as beans, peas, rice or other foods may be packed for shipment, display and sale.

One of the objects of the present invention is to provide a carton or container in which the articles packed therein may be exposed to view of intending purchasers, without opening the package or breaking the seal (when such packages are sealed).

Another object is to provide a carton or container of the class described, in which the v transparent window light or material is covered temporaril during packing, trans rtation and ban ing to protect such win ow light from damage prior to being sold and delivered to the ultimate consumer.

' Another object is to rovide a carton or container of the class 'escrib'ed, havin 8.

windowlight mounted in such a manner t at it may be cemented to the carton to form an air-tight 'oint there-between.

"With t e above and other objects in view,

which will more particularly appear from the following description, I-haveillustratedin the "accompanying drawings, the preferred style of my invention, and in said drawings I have indicated the" same part throughout the various views by the same reference numeral.

Figure'l is a plan viewjof a flat blank cut u out in the shape shown, andscore'd as indi cated for folding into a rectangularly shaped carton. f 1 Figure 2 is a front elevation of one of my gftgnsshowing the top open, ready to be e Fi' re 3 is asection viewof a portion of the ront walltaken along the line H showing the parts forming t e window light.

"shown two variations'of construction of my I cartons.v :The preferred style shown in Fig-,

'ure "3 is ada ted e'spec'ially'forthe packingof article s w ere 'it is r ",uired thatthe cartonj s'halltbe sealed a r fight to prevent de-r Figure 4 is a section view along the same terioration of the contents by air, moisture or other deleterious substances. The variation shown'in Figure 4 is equally useful for all purposes, excepting that the method of construction does not lend itself tothe manu facture of a carton which is alwaysperfectly hermetically sealed and is usable wherever the contents are not injured by air or moisture entering the carton through openings where the carton is not'perfectly sealed.

' In the manufacture of my said cartons, the first step is to stamp or cut out a blank as 1 shown in Fi 'ure 1, fromfa single flat sheet of heavy' car -board, straw board or'the like suitable material. At the top and bottom, the blank is cut to forin a plurality oflfla 11, and 13 .made integrally with the bl'an "for" folding over to' close the top and bottomends respectively. a suitable place in one of the walls of the carton as at 3 a cutis made in they blank, either circular, oval, or any other desired shape, partially cutting out a piece of the card-board as 16, butleaving a narrowportion to attach the disk 16: to the blank, for'thepur'poses hereinafter explained. The blank is also scored in the usual manner along the dotted lines to indicate and facilitate folding to form] the carton shown in transparent iece of materialTfof celluloid, glacine orot or similar .transpa'rent'lmaterial, of a size large enough to more than cover the opening formedbyjthe, cut 3, cut

out, preparatory to covering the said' opening. The edges of this piece of transparentf'material are carefully covered with any' suitable adhesiye, and it is attachedto thepart'which is to form the inside wall of the carton-by pressing firmly over the opening formed b the cut 3 and against the saidcard-boar until the cement sets firmly, as shown insec tion in Figured,

; Byfthis 'constru'ctiomwhen the disk "16 is re- "moved, as hereinafter explained, it leaves an opening in the wallof the carton, covered by the transparent material 7, forming a window through'wliichthe contents of the car'- ton may be viewed for inspection by-any intending purchaser, without the necessity of breaking the seals, or opening the flaps at the top of said carton. While this form of construction offers all the opportunity required to view and inspect the contents of said carton, as explained, yet by reason of the fact that it is diflicult, in practice, to make the adhesive spread evenly over the glazed surface of the transparent materials in general use, and the further reason that if the adhesive fails to spread evenly and cover the entire circumference of the said opening it leaves one or more places where air may enter the said carton, this construction is not always reliable for articles requiring to be hermetically sealed to preserve them against deterioration. To make the carton perfectly air tight, I prefer to attach the transparent window material 7 in the manner shown in Fig ure 3. In this construction the transparent material 7 is cut to the required size and shape, and two frames slightly lar er than 7 as 8, 8 are cut out of paper, card oard or other suitable material, each of said frames 8, 8 having a central 0 ning to correspond to the size and shape 0 the opening formed at 3 in the wall of the carton. Suitable adhesive is applied to both sides of the transparent material 7 near the edge and also to one side of each ofthe frame members 8, 8. The three parts are then assembled, with the transparent material between the sides of the frames 8, '8, the sides having the adhesive toward the member 7, with the frame members extendin without and beyond the trans arent member in all directions, and the t ree parts are firmly pressed together, preferably in a machine ada ted forthe purpose, with suitable heat applied thereto, to cause the adhesive to spread thinly and evenly over all of-the surfaces in contact, to provide a perfectly airtight joint when fully set. After this transparent window member has thus been formed and fully dried, adhesive is ap plied to the frame member 8 on one side of said member, and it is placed against the inner wall of the carton, with the opening in the transparent window member in register .vith the opening formed by the cut 3 in the carton, and the said window member is pressed tightly against said wall until the parts adhere fully and erfectly together, thus forming an a1r-tight1oint therebetween. By making the window member in the separate piece as above explained, it permits me to use suitable machinery to produce uniform and perfect contact and adhesion between the parts, and provides the window member with a surface to which the adhesive generally employed will adhere more perfectly to make the best and surest joint possible.

After the window member has been cemented to the blank 1 in either of the methods above described, the blank is folded along the dotted lines, and the edges 9 and 10 are cemented together, and the bottom flaps 11 are folded Over and cemented together to Earent material 7 covering said opening from eing damaged in packing, handling and shipping. The disk 16 might be cut entirelyout, if desired, but by leaving it in position until the merchant is ready to display or sell the goods, all likelihood of the transparent window being damaged is prevented and if preferred, lighter and less expensive material may be used, thereby reducing the cost of said carton. When it is desired to dlsplay the articles 12 enclosed within the carton, the

connection 15 at the bottom of the disk 16 may be severed, and the disk raised exposing the contents to view through the window opening. If desired, the disk may be left on the carton, and lowered again when through displaying, using the upper connection 14 as a hinge, or if preferred, the upper connect1on 14 may also be severed, and the dlsk entirely removed, exposing said window opening and the contents to view at all times.

By employing my said improved carton a manufacturer is assured that he can pack his product in his factory, and make certain that it will reach the customer in the same neat, clean and alatable condition in whlch it has left his actory. Further, it insures that the customer may inspect the articles which he is purchasing, and make sure before purchasing, that they are of the kind, size, and quality whichhe desires, and that they will be free from any damage from air, molsture, or insects, instead of buying sight unseen as is at present the case with all packed and sealed articles. It also insures that the articles have not been opened, and exposed to dust, dirt, or handling of any kind, which is greatly to be desired and will beblliighly appreciated by a discriminating u 1c. p It will be apparent that the size and shape of the carton are immaterial, so long as it is constructed in the manner above described. It will also be seenthat merchants, or others, desiring, may" purchase the cartons for putting up goods for display and for sale, as in the cash and carry stores, and the customer waiting upon himself, can see the kind and quality of the code offered for sale, without the-merchant ing required to mark each separate package to indicate the kind or quality. It will also be seen, that the factory packing a high grade quality of goods will be able to ShOW the better quality of his goods, and will have the advantage which such quality should secure in competitlve sales.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is the following A carton having an opening in the wall thereof; and a closure for said opening, said closure consisting of two fiat rings having perforations corresponding to the perforation in the carton wall and a transparent sheet interposed between said rings, the edges of said sheet being hermetically sealed between said rings and the outer of said rings being adhesively secured to the inner wall of said carton around the o ening therein.

In testimony hereof I ave signed the foregoing specification.
