SHIPPING CASE.

Application filed March 7, 1922. Serial No. 541,673.

' ping case which will effect a'very large saving in material over the common so-called slotted container and has full capacity for its dimensions as distinguished from the socalled reoessed end container. The so-called slotted container is one made from a single blank in which the bottom and top of the case iseach formed by two pairs of relatively large overlapping flaps. This container has been very satisfactory in the past but it requires a far greater.

amount of material than the container about to be described. Where some of the large industries ship thousands of these containers a day a small saving in material amounts to thousands of dollars in the course of a year. Hence it is the aim of all large shippers to adopt for their shipping departments shipping cases which use a, minimum amount of material, which afl'ord the maximum strength, and which require as little labor cost in their preparation as possible.

Thec0ntainer about to be described fulfills all these aims and has other advanta es which will appear when a detailed description has been given.

In a prior patent, No. 1,414,067, April 25, 1922, a case of this general character is described, but such prior patent claims only the double or bellows-like sealing flap. This double orbellows sealing flap construction may or may not be used with the shipping case constructed of the blank here used and put together in the way here described. In a prior patent 1,452,588, April 24, 1923, the method of sealing a shipping case which is described and shown in this application is described and claimed. However, this method of sealing can be used on the slotted container or a difl'erent form of container and hence is a separate invention. In Patent No. 1,430,151, reissued as Patent No. 15,775, the preferred method of constructing the box described and claimed in this application is set forth and claimed. However, the box here described and claimed can be constructed by other methods than that claimed in such patent but not nearly as advantageously. In Patent No. 1,430,150, Sept. 26, 1922, a machine for stitching a container along the lines of said method is described and claimed.

Referring to Fig. 3, it will be seen that three blanks are used, one a main body blank which has the bottom wall a, side walls b and o, and the sealing flaps e and d. This blank is a rectangular blank with scorings orweakened lines along which it folds. The end blanks are rectangular blanks with shallow c0rner flaps a formed thereon by cutting out the corners and providing scor' ings. These end blanks are designated f and .g. The corner flaps mare very shallow; in fact, they only have to be the wdth of material necessary to hold a wire stitch.

Now refrring to Fjig. 9, it will be seen that the main blank can be set over a pair of anvils h and 2'. The end blanks can be lapped over the sides of thejanvilswith one comer flap of each end blank turned Over the side wall c. Simultaneously a lineof stitches can be taken through each corner flap in accordance with the method described and claimed in reissue Patent, No. 15,775, and by a machine such as described and claimed in Patent No. 1,430,150.

over the anvil, as shown may be pulled out Fig. 10, and the same in the drawings,

operation taken to unite the comer flaps to the bottom wall of the case, and finally, the main blank may be pulled out another step, as shown in F ig. 11, and the corner flaps of the end blanks stitched to the final side wall b. It will be noticed that the stitches in each. side and bottom wall are not taken in sequence, as for instance, with the final side wall b. The stitch 13 is first taken at one end and then the stitch 14 at the opposite end, whereupon the stitches then follow in sequence. This is not absolutely essential but it is an advantageous operation in connection with the machine described and claimed in Patent No. 1,- 430,150.

When the case has been thus constructed it may be packed and sealed in acc0rdance with the method described. and claimed in Patent No. 1,452,588, to-wit, a blade anvil jis first inserted between the large sealing flaps e and d and under the end blank sealing flap lc, as shown in Fig. 6. The

stitches

1, 2, 3 and 4 are then taken, leaving an unstitched portion at the middle through which the anvil may be inserted to take

stitches

5, 6, 7, 8, 9 and 10 along the line of the meeting edges of the large sealing to the bellows-like flap.

flaps e and d. Then the anvil may be swung around to take the

stitches

11, 12, 13 and 14 to stitch the two large sealing flaps e and d to the end blank sealing flap m. The anvil may then be withdrawn and the stitch 15 taken between the two large sealingflaps e and d as shown in Fig. 7. This leaves a slightly open space where the final stitch is taken because the sealing flaps are not united to the underlying end blank flap k. By using the bellows-like flap described and claimed in Patent. No. 1,414,067, this objection is overconie. At the same time, in some places the present construction is preferable The great advantage of this type of conta mer over a slotte container is that it ehm1nates one pair of deep flaps used on both the top and bottom of the slotted container. These deep flaps are alwaysused on a slotted container for they are considered necessary for the silicate form "of seal-' mg,.and even were my wire stitching form of sealing used, it would be no advantage to lessen their depth because this would only be waste. These end flaps all have to be of the same depth in order to cut out a uniform "rectangular blank. Any variation of their depth results in simply wastihg material.

The so-called recessed end case has a blank construction somewhat similar to mine but this case does not clinch the stitches on the inside of the container; in fact, the recessed ends are used for the very purpose of clinching the stitches on the outside of the container to permit sealing of the container.

'With the recessed end box the full capacityof the box in accordanee with its dimensions 1s not ach1eved. Consequently the box 1s not as -econom1cal as mme e1ther in the amount of material required or in the room required Furthertwo sets of wide flaps at the bottom of the slotted container, substituting in place a single, solid wall. ,This, of course, effects a very large saving in material, which runs into a great deal in the course of a year. Furthermore, my container has a reinforcement stitched around all corners of the box,

which makes it very much stronger than either the slotted container or the recessed end container. It is stronger than the slotted container because the slotted container does not have a double wall at the c0rners. The recessed end case does have a double wall at the corners but this\ wall is a projecting and an exposed one and it makes it easy to tear.

By the use of a machine such as shown in my atent No. 1, 430,150, which simultaneously stitches both ends of theblank, ractically no more labor or eort is re uired in stitchin the box and setting it up t an is the case With the slotted container.

It will be obvious that the comer flaps can be stitched to the inside of the side walls and bottom walls in place of the outside without altering the principle of the invention, so the statements in the claims must be much stronger.

. It will also beobvious that the position of the comer flaps as to the blanks and the l0 cation of the narrow and bread sealing fla s in the several blanks might be shifted wit out departingfrom my mvention, hence the claims have been acco1dingly formulated to cover such changes.

What I claim is: V

1. A shipping case of foldable board, com prising three separate blanks someof Which are provided with integral foldable comer flaps, two of the blanks being end blanks forming each an end of the case, the remain ing blank forming the bottom and two side walls, the end blanks being set in substanand held there by the comer flaps being folded and secured to the adjoining blank,

the three said blanks being provided at top or charging side of the case with an aggregate of three or more sealing flaps each integral with a blank, all folded in, and some overlapped and the adjacent flaps stitched to ether without the material of the case being slotted to effect such stitching.

2. The combination stated in claim 1 in which there are four sealing flaps with two being relatively narrow and stitched to the other two flapsalong the length of the narrow flaps.

3. The combination stated in claim 1 in which the comer flaps are integral with the end blanks and stitched to the body blank.

4. The combination stated in claim 1 including four sealing flaps two of which are relatively narrow and integral with the end blanks.

5. A shipping case constructed of fibre board or equivalent material, comprising three separate substantially rectangular blanks cut and creased to provide two independent end blanks and one independent body blank, some of the blanks provided with integral shallow corner flaps that are foldable to lie against the .adjoining blank with the ends of. the case substantially flush with the ends of the body blank when the latter is folded up to form the bottom and two side walls of the case, the corners thus formed being substantiall clear and unobstructed inside and out, t e said three separate blanks arranged to present at the top of the case where it is charged a set of three or more sealing flaps'each integral with a blank, all of which fold in and some of Which overlap and two of which are relatively narrow, means for fastening the corner flaps to the blank or blanks againstwhich they lie, and means for fastening the narrow sealing flaps to the remaining sealing flap or flaps, said last mentioned means conslsting of fasteners driven in and clinched, without the material of the case being slotted to efl'ect such clinching.

- 6. The combination stated in claim 5 with the narrow sealing flaps integral with the end blanks.

7. The combination stated in claim 5 with I
