6 Claims. (Cl. 229-39) This invention relates to a carton and, more particularly, to a satchel-shaped carton.

The main objects of the invention are to provide a carton of attractive style and one which may be easily set up from pre-fabricated collapsed condition to open merchandise receiving condition, and then readily closed; to provide such a carton in which the structure is effectively locked in its set up position and also effectively locked in closed position; to provide such a carton with a convenient carrying handle; to provide a readily collapsible carton of the character indicated which, because of its shape or style, lends itself to the incorporation of toy or like cut-outs so that the carton, itself, may constitute a gift of toy or other cut-outs in connec tion with the sale of other merchandise; to. provide a carton of the character indicated which will provide a sturdy container for goods to be packaged and transported therein; and, in general, it is the object of the invention to provide an improved carton of the character indicated.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawings (2 sheets) in which there is disclosed a carton embodying a selected form of the invention.

In the drawings,

Fig. 1 is a plan of the blank from which the carton is formed;

Fig. 2 is a plan of the blank in preliminarily folded and glued condition to form a collapsed carton in condition for storage or shipment, and

,which collapsed carton may be readily set up .manually into carton forming condition;

Fig. 3 is a perspective illustrating only the lower portion of the carton and a detail of the means whereby the carton is locked in set up condition;

Fig. 4 is a perspective view of the carton in set up open position;

Fig. 5 is a fragmentary perspective illustrating a step in the procedure of closing the carton;

Fig. 6 is a perspective view of the carton in closed condition, and

Figure 7 is a cross section on the plane of the line of Figure 6.

As shown in Fig. 6, the carton embodies a carrying handle I which projects upwardly from the ridge portion 2 of a gable-like upper carton portion embodying top Wall sections 3 and 4. The top wall sections 3 and 4 are foldably connected to lower parallel side wall sections 5 and 6. End walls I and 8 connect the opposite side walls 5 and 6. e

- The container is formed from a blank such as shown in Fig. 1, wherein the above-mentioned cartonportions are identified by the same reference numerals.

- In addition to the various parts already identified there are provided bottom forming flaps 9, l0, H and I2 which extend from and are foldably. connected to the lower edges of the I walls 8, 5, 1 and 6 respectively. v

The blank structure shown in Fig; 1 is initially folded on itself on fold lines I3 and M which define the corners between the walls 8 and 5 and the walls I and 6 respectively. By such folding of the blank, the free end I5 of the blank is brought into'registry with the opposite end [6 thereof and a glue .fiap I! on the end l5 brought into underlying relation to a marginal side portion of the flap 8 to which it is adhesively or otherwise secured. In thismanner the blank is converted into a collapsed or flattened tube and it will be understood that the collapsed blank may be readily distended to form a substantially rectangular, tubular body.

When the blank is so distended, the end wall bottom flaps 9 and H may be folded inwardly into mutually overlapping relation over the bottom of the carton body after which the flap l2 may be folded into overlying relation to the end wall flaps 9 and II. Then the side wall bottom flap I0 is folded forwardly from the back wall 5 under the flaps 9, I I and I2, thereby to form a four-ply bottom structure.

The bottom panel In is preferably of outwardly tapered form as shown in Fig. 1, and is provided with a reduced widthextension l8 and a locking fiap l9 which has end ears 20, 20. The end ears 20,, 20 are foldable relative to the locking flap l9,

suitable fold lines Zl being provided for that purpose.

When the bottom flap I0 is folded to bottom position, theextension l8 and locking flap I9 will initially project forwardly as shown in Fig. 3. The flap I8 is then folded upwardly on a fold line 22 provided for that purpose thereby to position the locking flap portion l9 in overlying relation to a displaceable ear 23 which is formed in the front wall 6 by means of a U-shaped slit 24 and a fold line .25. The ear 23 may be displaced inwardly by being swung about its fold line connection 25 with the front wall, such displacement being elfectable as an incident to inward folding of the locking flap [9 about a fold line connection 26 between the locking flap and .said extension I8.

The length of said locking flap is somewhat greater than the length of the displaceable car 23 so that the end portions 232 of said locking flap will necessarily be folded out of the normal plane of locking flap to permit passage of the flap through the opening in the front wall 6.

As soon as the locking flap has passed through the opening in said wall 6, said ears 28 will spring out to resume approximately their normal or initial co-planar relation to the locking flap proper, thereby to prevent return or unlocking movement of the flap l9, through the front wall opening. Said locking flap I9 is adapted to be folded downwardly on the inside of the front wall 6 and the front wall ear 23 returned substantially to its normal front walLposition approximately as shown in Fig. 4. Merchandise packaged in the container will, of course, serve to hold this ear 23 in its closed position as shown. After the bottom structure is locked in place as explained, the carton'is in its set up, open position as illustrated in Fig. l.

The rear top wall panel 3 of the carton has its opposite ends connected by triangular webs 21 and 28 to the rear inclined top edges 29, 23 of the opposite end walls l and 8. These triangular connecting gussets 2'! and 28 are joined to the top wall flap and the respective end walls by suitable fold lines connections and they are also provided with intermediate centrally disposed bisecting fold lines 38, 30.

To close the carton, the triangular gussets 2'! and 2B are first folded inwardly upon themselves substantially as shown in Fig. thereby bringing the top wall portion 3 into the plane of the angular edge portions 2d of the end walls. The front The handle structure I is formed integrally with the front top wall portion 4 by means of extensions and 34, the extension 33 being foldably connected at its ends as indicated at 35 to the upper edge of the front top wall portion 4. The extension portion 34 is hingedly connected as shown at 3t to the adjacent end of the handle extension 33. These extensions 33 and 34 are provided with openings 3?, 3? which substantially register when the extension 34 is folded on the fold line 36 into face to face engagement with the extension 33. The extension 3 ihas a base portion which is foldably connected to the body of the extension part fold lines 393 which substantially register with the fold lines when the extensions are folded into face to face relationship on the fold line 35. The extension at is initially folded and adhesively secured in face to face relation to the inside of the handle extension 33. End portions of the base 38 of the extension 34 project beyond the main body of the extension 34 as indicated in Fig. 2.

The handle structure formed as aforesaid, is inserted through a slot 46 provided in a flap 4! which extends from and is hingedly connected as shown by the aligned fold lines 42, 12 to the upper end of the rear top wall panel 3.

This flap M is then folded downwardly about the fold lines 22 into face to face engagement with the front top memberst as shown in Fig. 6. The

carton results.

handle I will then project upwardly beyond the ridge 2 (which coincides with the fold lines it, 12) so as to provide a centrally disposed handle whereby the closed carton may conveniently be carried. The handle has one of its two plies integrally connected to the top wall t and the other of its plies is anchored against withdrawal from the slot 49 by engagement of the end portions of the base 38 with the inside of the ridge 2 of the carton. Thus the handle is very effectively at tached to the carton and cannot readily be torn therefrom.

The carton is more or less effectively looked in closed position merely by the insertion of the handle through the slot id as already explained. However, additional locking may readily be provided to even more effectively lock the flap il in its closed position as illustrated in Fig. 6. Such additional locking means may consist, for example, in the provision of a displaceable ear lock section G3 formed by a. pair of slits M, it and a connecting fold line in the front top wall 1 and a notch or opening at in the ti Ears ll, ll integral with the flap ll project into the notch to reduce its effective length to somewhat less than the length of the car 33 of the front top wall. Said ear 53 is provided with transverse fold lines 48, 48 which permit end portions of the ear to fold out of the plane of the car as an incident to forced passage of the ear through the opening l t. When closing the carton, the top panels are folded to their gableforming position, the handle i being passed through the slot it and the flap li folded down over the panel 4. The ear 43 will then be disposed under said flap 4| but readily accessible through the opening lli. Said ear 43 may then be pulled facewise outwardly about its hinge line 5, through said opening the end or tab portions of said ear being incidentally deflected on the fold lines 48 by the ears or lips ll? until said ear 43 and its end tabs are completely through said opening. The tabs thereupon return automatically to approximately their normal coplanar relation with the intervening portion of the ear, whereby said end portions will overlie ear portions 41 at the opposite ends of the opening 6 to thereby resist unfolding of the iiap ti and opening of the carton.

As shown in Figs. 1 and 2, the bottom edge l9 of the opening 37 in the handle extension Ed is cut so that it extends below the upper edge 553 of the ear 43 when the handle forming portion 34 is folded and secured in handle position as illustrated in Fig. 2. In this manner the free upper edge portion of the ear 43 is readily engageable for displacement of the car from the top forming panel l for locking insertion through the opening 2 in the flap 5!.

When the carton constructed and set up in the manner explained, a very rigid and durable It embodies relatively large unbroken areas adapted to carry ornamentation or advertising material and in which various cutouts may be formed. 35y cut-outs reference is made to toy and. similar paper cut-outs which are to be displaced from the walls of the carton to provide independent novelty articles, toys or the like. In some instances, it is preferred to confine the cut-out areas to the inside bottom flaps 9, II and I? which of themselves provide a substantial amount of area to carry a goodly number of small cut-outs or several larger cut-outs. These flaps or, at least, substantial portions of them may be removed while still retaining a complete bottom for the carton.

Various'changes in the describedstructure and the details thereof may be made while retaining the principles of the invention.
