which can be sold and shipped as such, or as a sub-assembly or tubular form or as a further partial assembly in which the bottom wall flaps and certain of the top flaps have been located and connected: and in which the assembled container is of depth capable of holding piece goods in the bolt and of receiving such bolts through an opening provided in such further partial assembly by a front door structure formed in the originalblank and having connected therewith top wall flaps which upon closing of the door structure serve to stiiien the container during transit; and in which the assembled container can be opened byreleasing said door structure, whereafter the container can be employed for accessibly storing the contents while the closed door structure serves to exclude dirt.

Another feature of the invention is the provision of a container and a blank thereforoi fiber board, corrugated board and like stifily flexible materials herein referred to as fiber board; wherewith the same may be cut and shipped .in

the flat or in a sub-assembly conditiomand .set up and its parts connected read to receive the contents, with side, bottom and rear walls con-- nected with one another and with parts :of the 1 top and front walls likewise connected, while other parts of the top and front walls can swing about hinge lines provided by the blank material itself whereby to permit easy loading and unloading.

.A further. feature is the provision of such a container and the blank therefor, in which the swingable parts of the top and front walls are connected together at hinge lines provided by theblankmaterial itself, and when in closed positions come into alignment and abutment with other parts of the container assembly whereby the contents can be sealed off by closing tapes extending in planes across abutment lines and extending around abutment corners.

A further feature is the provision of "such a container and a blank therefor, having a total height in excess of the reach of the normal packer :(e. g. :greaterthan 28 inches) andzso-conformed and arranged that the packer has reach- 2 ing access to the inner bottom wall for aligning and avoiding distortionhof the contents at the bottom.

With these and other features as objects .in view, as will appear in the course of the following description and claim, illustrative forms of practicing the invention are shown on the accompanying drawings, in which:

Figure 1 .is a lay-out diagram of a blank for the construction of a first form of the container.

Figured is a perspective view of the same container, in fully assembled and closed condition, ready for shipment.

Figure 7 is a perspective view indicating the collapsing of a container sub-assembly at the factory for flat shipment.

The blank of Figure l is .ofrectangular outline, and it will be noted that there is-essentially no wastage. of material. The illustrated containers have two wide wallsand two narrow walls sothat they are oblong horizontal cross-section, wherewith the wider walls are herein designated as front and .rear panels, and the narrower walls are designated as side panels, but it will be understood that this is intended as illustrative and that the-container may have various hori- .zontal cross-sections as .best adapted .for the goods to be packed.

The blank of Figure :1 hasthe successive arrangement of'a side wall all), a rear wall H, a side wallula-Z, and -airont wall comprised of two sub-panels I3 and I30, separatedby aweakening line illustrated as a horizontal cut 14. These wall panels are separated successively from one another at .fold lines :15 which will later provide vertical hinges or edges in the assembly. Correspondingly, the wall panels are connected acrossruppertold "lines il 6:1with corresponding top naps 20., 21, 22, 23, these .flaps being separated successively from one another by cut lines tor gashes 24. likewise, each ctr-the panels. is :connected across a doweriold line 25 with a correspondingbottom :flap .130, 3|,32, 333; theseibdtblank of Fig. 1. provided by the out line I4 can be less than 28 tom flaps being successively separated from one another by the cut lines or gashes 34. The lines I5, I6, 25 are fold lines in the assembly of the container: and it is preferred to assure folding at predetermined locations by scoring the blank along these lines. It will be noted that the blank can be formed from fiber board, corrugated board, etc., by the usual factory operations of punching with cutting and scoring rules, or by the use of cutting and scoring rollers, or by use of band or other saws for cutting the edges and gashes, or by various combinations of these and other operations known to box manufacturers.

The blank of Figure l is preferably partly formed at the factory, by employing a fabric tape 40 to join the free edge of the front subpanel I3 to the corresponding part of the free edge of the side panel I9, therewith folding the various panels about their hinge lines I5 and forming a prism which can then be crushed down (Figure 7 by pressure in the direction of the arrows, to form a flattened structure of double the thickness of the original material. Thus, the boxes can be sold and shipped in flat condition from the factory to the packer.

' When the packer desires to employ the container, he continues with a partial assembly by opening the flattened illustrative container to rectangular tubular form and folding the bottom 'flaps 3|], 32 inward and then folding the bottom flaps 3|, 33 inward so that two layers of flaps are formed, with use of a cemented tape 6i over the abutting edges on the flaps 3!, 33, and continued around the horizontal edges and onto the side walls I0, I2. Tapes 42 may also be employed over these horizontal edges, for connecting the flaps 3|, 33 with the side walls III, I2 and sealing these edges. The top flaps 20, 22 are similarly folded inward and then the flap 2I is brought over them (Figure 2) and the short tapes 43 are applied over the edges of flap 2| and side walls III to secure the parts and seal the container along these lines. It will be noted that the structure can be sold and delivered in this form.

In this condition as shown in Figure 2, the top panel portion I30 of the front wall can be swung to the side, with its flap 23, about the vertical hinge provided in the blank material by the corresponding fold line I5; and the packer thus has access to the interior of the container above the cut edges of the lower panel I3 of the front wall, provided by the out line or gash IA of the As indicated above, the edge inches from the floor, when the box is standing in the position shown in Figure 2, even for a container having a total height exceeding 60 inches. For example, with a 50 inch container,

the line I4 may be placed 20 inches from the floor or bench, whereby even a short woman packer can deposit articleswith care upon the bottom wall of the box. This is of great value, as it avoids crumpling of piece goods at the bottom ends of the bolts.

The lading is built up within the container, in the case of packing folded textile goods or individually-packaged articles, with a sliding of the last row or rows of articles into position top panel I33 comes into alignment with the top edge of the lower panel I3 so that the panels [3, I30 are co-planar. In this position of parts, a cementing tape M can be pasted over the adjacent edges of the panels I3, I30 and around the upright edges of the box onto the side walls l0, I2. Also, a tape 45 can be cemented over the vertical edge provided by the upper panel I30 and the side wall I9; tapes 46 can be cemented at the top horizontal edges to join the flap 23 with the side walls I3, I2; and a tape 8'! can be cemented over the co-planar surfaces adjacent the abutment of the top flaps 2|, 23, carrying this tape 41 down onto the side walls I9, I2. Thus, the completed package as shown in Figure 3 has its edges joined and sealed by tapes for providing strength and preventing loss of contents, penetration of dirt, or pilfering.

In the modified form shown in Figures 4 to 6, the rear blank has in succession a side wall panel '50, a rear panel 5!, a side wall panel 52 and a front wall provided by a main panel portion 53, and an upper sub-panel portion 253, I53; these panels being successively connected across fold lines 55. Fold lines 53 define connections of these vertical wall panels with corresponding top flaps 33, SI, 62, 63 and I33; the flaps 53 and I63 together providing a top flap structure for the front wall. In corresponding fashion, fold lines 65 provide connection of the vertical wall panels with the bottom flaps 10, II, I2 and 13. The top flaps are separated successively by the gashes 64, and the lower flaps by the'gashes 14. The individual flaps 33, I33 are separated from one another by a weakening line I63 shown as provided by longitudinally aligned slits cut through the material, this line of slits being continued onto the front wall to provide for separation of the front wall sub-panels 253, I53, in conjunction with a similar weakening line I61 extending horizontally on the front wall to provide separation of sub-panels 253, I53 from sub-panel 53. Thus, the blank of Figure 4 can be manufactured as described above for the blank of Figure l, partly assembled by use of a vertical edge tape 33 (Figure 5) connecting the front panel 53 with the side panel 59 corresponding to -with their corresponding flaps, remain integrally joined with the portions comprising the panels I53, 253 and flaps 63, I63.

At the packers plant, the blank is set up in essentially the same manner as described for structures Figures 1 to- 3, wherewith a partially assembled container as in Figure 5 is produced. The weakening lines I66, I61 are broken through and the upper doors provided by the panels I53, 253 are swung sidewise about their vertical hinges provided respectively by the upper part of the tape and by a fold line 55,-carryingwith them their top flaps 33, I33, for example to the positions shown in Figure 5, in which packing can be accomplished in the manner described for the form of Figures 1 to 3. Here, also, the container can be sold and delivered in this state of assembly. When packing is completed, the door panels I53, 253 with their flaps are swung to closed position and the sealing tape 84 (cor responding to tape 45) applied across the abutment edges of the front wall panels 53, I53,..253,

with the ends of the tape extending onto the side walls 52, 50. Tape 85 is cemented across the abutment edges where the panels 153, 253 join, with this tape 85 being extended also over the top of the container to connect and seal the top flaps 63, I63 and being carried past their abutment with the top flap 6|. The tape 86 (corresponding to tape 41) is cemented over the abutment of the flaps 63, I63 with the flap 6|, and has its ends carried over the horizontal edges and onto the side walls 50, 52. Tapes 46 can be used. Thus, this form of construction likewise provides a strong and tightly sealed box, as shown in Figure 6, with smooth external walls having the various lines of abutment and edges of juncture of the door structure and flaps connected and sealed by cemented tapes.

Each of these packages, upon arrival at the retail store, for example, can be easily opened by splitting the tapes 44, 45, 46 and 41 for the form of Figures 1 to 3; or the tapes 84, 85, 86, 45 for the form of Figures 4 to 6. This frees the doors so that they may be opened with their flaps to the positions shown in Figures 2 and 5, respectively, and part or all of the merchandise can be removed. It will be noted that the containers form excellent storage boxes at the store, as the door structures can be swung closed again without trouble, and can be held in closed position by a short piece of tape, thereby preventing the entry of dust or dirt to the goods remaining in the container.

It is obvious that the invention is not limited to the illustrative forms of construction, but that it may be employed in many ways within the scope of the appended claim.

I claim:

A tall upright container formed from a onepiece fiber board rectangular blank out and scored so that when assembled a shipping container is provided comprising a rear panel, a front panel and side panels, each of said panels having an integral flap forming a bottom end closure on which said container normally rests and is packed, said panels being dimensioned so as to provide a packing space of greater depth than the normal reach of a packer, said side panels at their upper ends having integral flaps folded into a common plane and said rear panel at its upper end having an integral flap folded down onto the side panel flaps and secured to the side walls by taping, said front panel being divided horizontally approximately midway its height to provide upper and lower sub-panels, said lower sub-panel being rigidly connected to the side panels to define with the side and rear panels a packin space beneath the upper terminus of said lower panel which has a depth not exceeding the normal reach of a packer, said upper sub-panel being initially connected to one of said side panels so as to swing outwardly and form an access opening for packing the container, said upper sub-panel having an integral flap dimensioned to overlie the upper side panel flaps, and abut the free edge of the upper rear panel flap, said container being closed by swinging said upper sub-panel into the same plane as the lower sub-panel with its integral flap overlying said upper side panel flaps and with its free edge abutting the free edge of the upper rear wall flap and by taping said last named abutting edges, the adjacent edges of the upper and lower subpanels, and the free side of the upper sub-panel to the adjacent side panel.
