UNITED STATES ARTHUR W. SCOTCHER, OF NEWARK, NEW JERSEY.

o m'ron.

Application filed February To all whom it may concern:

Be it known that I, ARTHUR W. ScorcH- ER, a subject of the King of Great Britain, and a resident of Newark, in the county of Essex and State of New Jersey, have invented an Improvement in Cartons, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My invention relates to cartons or containers for general use and more particularly aims to provide an improved collapsible or fiat-packing carton adapted for the packaging of fragile articles, such as eggs or the like. As to all common subject matter this application is a continuation of my copending application, Serial No. 714,017, filed May 17 1924.

In the accompanying-drawings illustrating by way of example one embodiment of my invention:

Fig. 1 is a plan view of a blank for forming a carton embodying one form of my invention;

Figs. 2 and 3 are respectively plan and end views showing an intermediate stage in the formation of said carton;

Figs. 4 and 5 are respectively plan and end views of the complete carton in. collapsed position as for shipment;

Figs. 6, 7 and 8 are end elevations illustrating successive positions assumed by the carton during the setting up and filling of the same;

Fig. 9 is a horizontal section through the carton on substantially the line 9, 9 of Fig. 8;

Fig. 10 is a vertical partial section through the container substantially in the plane indicated by the line 10, 10 of Fig. 9.

Referring more particularly to the drawings, the construction of a carton illustrating one embodiment of my invention will be most readily understood by reference first to the blank from which it is formed. A blank suitable for the'purpose is repre sented in Fig. 1. As shown it is rectangular or substantially so and of a width the same as the length of the carton to be formed. Said blank is wholly devoid oftongues, tabs, cut-outs or like irregular formations upon any of itsedges. Consequently there absolutely no wastage of stock, which may be cardboard or other suitable material. In

20, 1925. Serial No. 10,544.

said figure, as well as inFigs. 2 and 4, full lines indicate cuts while dotted lines indicate scores or creases" for folding. Said single blank from which the carton preferably formed comprises a plurality of substantially rectangular, parallel, strips or portions symmetrically, disposed at opposite sides of the vertical median line 10.- Along said line 10 the blank is preferably cut over at least the greater portion of its length and perforated along any remaining portion. At the opposite sides of said line 10 saic one-piece blank includes the strips 1, 1 respectively constituting securing or glue laps. At either side of said laps 1, 1 are the partition platforms or transverse- partition forming members 2, 2. Outside of the latter there follow in order the substantially central longitudinal partition me1nbers 3, 3, the bottom or floor portions 4, .4, the opposite members 5, 5 and the opposed cover members, each of the latter including a main cover portion 6 and a flap or tuck 7 Said various carton portions are defined by scores or creases, indicated by the dotted lines 11, 12, 13, 14, 15 and 16 in that order, reading outwardly from the central line 10 and in opposite directions. I

At the opposite ends of the platform strips or portions 2, 2, lying respectively between the lines 11,12, cross pieces or braces 17 1.7 are provided, intermediate which said portions 2, 2 are cut, as indicated by the full lines 18, 18 etc., to form the series or row of flap-like spacers or transverse partitions 19, 19, etc. The end spacers 19 of each row or series are preferably somewhat wider than the others, substantially as shown. The remaining spacers 19 are supported in pairs, each such pair being adapted to be folded downwardly along one of the transverse dotted lines 20, 20,

etc. to form a transverse partition, in the manner best seen in Fig. 10. A-cell or compartment for". the reception of one or more articles is thus formed between each of said dotted lines -20, 20, threecornered sections 21, 21, etc. being provided at diagonally op posed corners of each'cell, affording additional support for the spacers 19 and for i the articles to be received.

Desirably said spacers are not cut entire 1y through on the lines 19 but are left united by a portion of stock at one or more .the strips or members 3, 3, for example, the

member 3 at the left of the line 10. as indicated by th stippling in Fig. 1. The blank is then folded upon said line 10, marked w-a: in Fig. 1, for convenience in identifying it, one half or main section ofthe blank being doubled over flatu'ise upon the other half or main section, into the position illus trated in Figs. 2 and 3. In Fig. 3 the heavy line between the juxtaposed members 3, 3 indicates that said portions are glued or otherwise secured together flatwise.

Adhesive is next applied to the two laps 1, 1, both above and below the doubled blank as shown in Figs. 2 and 3, the upper lap 1 being stippled in Fig.2 to indicate glue or other suitable adhesive. end portions of the carton blank, each including one of the portions 4. 5, 6 and 7, are then folded upon the respective lines 13, 13, identified by the mark w-w in Figs. 2 and 3, said portions being swung away from each other and folded in opposite directions over onto the respective carton sections 1,- 2, 3, assuming the position illustrated in Figs. 4 and 5. It will be observed that the inner faces of the upper portions of the side members 5, 5 are thus brought into contact with and secured to the respective portions or glue laps 1, 1.

The carton is then complete. In the flattened or collapsed form illustrated in Fi s. 4 or 5 the desired number of cartons may be compactly stacked or bundled for handling or shipment to the trade. Due to the flat form of the collapsed carton and the absence of all projections, cuts or other irregular formations the cartons are extremely easy to handle and are not readily damaged, with consequent great saving in labor and waste in bundling. Similar saving also follows by the avoidance of all separate fillers,-partitions or other pieces such as employed in devices such as disclosed, for example. in the patent to Carter 927,488 of July 13. 1909, my invention being an improvement in this and other substantial respects over the device of said patent.

In Fig. 6 I have illustrated a. carton in partially opened position preparatory to filling the same. The two opposed main portions of the carton are grasped and opened outwardly and downwardly, substantially in the manner of opening a book. The two portions 1, 1 if not previously entirely separated along the line 10 during the The two opposed course of manufacture, readily become separated during the opening of the carton. In Fig. 7 a carton is shown in open position for .filling, said figure also clearly illustrating the manner of closing the carton cover or covers.

When it is desired to close the carton the opposed cover portions are preferably depressed into substantially the dotted line position illustrated in Fig. 7, the flaps or tucks 7 being brought into contact. Upon further .depressing said cover portions, it will be found that at a certain predetermined point they will spring down into closed position. Their main portions 6, 6 then lie in substantially the same plane and are automatically locked or retained in said position. The cover portions 6 and 7 are so constructed and arranged that said self-locking action occurs approximately at the time when the lower portions of the tucks 7, indicated by the letter a, Fig. 7, cross a horizontal plane adjacent the tops of the carton sides, indicated by the line a, b in said figure. The main cover portions 6, 6 have a width somewhat exceeding that of the floor portions 4, 4. Due to said relative dimensions and the described relations of the parts the above self-locking effect is produced, the opposite sides of the carton above the partition platform being sprung apart during the closing of the covers. a The maximum extent of such springing occurs substantially at the time the point 0 or other predetermined portion of the covers crosses a predetermined plane, herein represented by the line a, 6. Below such point the sides are permitted again to approach each other but still remain under sufficient tension to hold the cover closed, as seen in Fig. 8. The above self-locking effect is in the nature of a toggle-action in which the covers cross center during closing and are consequently automatically retained in closed but readily openable position. If desired the covers may be sealed by placing a strip of adhesive tape or the like across them.

It will be observed that the partition platforms 2, 2 lie in a plane substantially paral lel with and intermediate the bottom and cover portions of the carton. They are rigidly supported both along the sides and along the longitudinal central portion of the carton, being integral with the longitudinal partition members 3, 3, while the latter are secured together and themselves integral with the floor members 4. 4 respectively. In this manner the partition platforms are rigidly braced, the construction being such as to afford maximum strength at substantially the points upon the opposite sides of the carton at which it will ordinarily be grasped in handling. In these and other important respects above pointed out my invention constatutes an improvement upon the device disclosed in the patent to Stein 1,003,013, dated September 12, 1911. Said partition platforms 2, 2 are so located that the vertical distances between them and the cover or the floor respectively are less than the shortest I dimension of the articles to be received, such as eggs, whereby escape of said articles from one compartment to another or at the ends of the carton is wholly prevented.

It will now be understood that a carton embodying my invention may be inexpensively made and is extremely simple to manipulate both in packing flat for shipment and in setting up, filling and closing. Due to its regular formation it requires much less stock than cellular cartons of like size heretofore known. My invention is not limited to the provision of any particular number of cells or compartments. Obviously if less or more compartments of similar size are desired a narrower or wider blank may be employed. For example, a carton having a half-dozen cells may be formed from a blank substantially one half the width of that used in forming one-dozen-cell cartons. Ordinarily half-size cartons require approximately two-thirds the stock of a full-size carton. While the carton in accordance with my invention is preferably formed from a single blank, a filled carton may readily be separated longitudinally if it is desired to dispense but one-half the articles contained.

My invention is not limited to the illustra'tive embodiment thereof herein shown and described.
