7 claims.

This invention relates to a shippingl case which is designed to be made from paper board or ber- `board. Shipping cases of our invention are to receive and carry relatively heavy merchandise, such as bottled goods and, therefore, require particularly that they be cfa strong and durable character and fully capable of withstanding the strains to which subjected in use. Our invention has for one of its objects the provision of a very novel construction of bottom for the case which is of great strength and which can be produced very readily and economically.

.In conjunction with shipping cases of .this character, the bottom structure which we have devised is of utility irrespective of the particular top closure which is used.` With certain types of bottled goods, such as beer, it is very desirable that the light be excluded, and our invention has for another object and purpose the provision of a novel character of top closure and end structure whereby the ends of the case are strengthened and the necessary hand holes for carrying the case are covered to exclude light, yet such hand holes maybe used with subel stantially as great ease as though not thus covered.

A further object of the invention is to provide a novel structure of shipping case having bothV the bottom closure and end structure advantages stated, made from a single piece of paper or. yfiberboard, which can be shipped in a flat condition and set up at its destination ina very of a minimum of fastening staples and of Astapling machinery. Further, the amount of waste in conjunction with the paper or flberboard stock from which the blanks are cut is reduced to a minimum; and because of the at character of the blank, all in one continuous piece, from which each shipping case is made, there results a desirable facility in printing advertising data or the like upon selected outer sides of the case.

These and many other advantages not at this time specically stated will appear upon an understanding of the invention from the following y description, taken in connection with the accompanying drawings, in which, Fig. 1 is a planv of the shipping case blank from which the completed case is made.

Fig. 2 is a horizontal section through the shipping 'case of our invention, substantially on the plane of line 2-2 of Fig. 3.

Fig. 3 is a longitudinal vertical section sub..l stantially on the plane of line 3-3 of Fig. 2,

Fig. 4 is av transverse vertical section substantially on the plane of line 4--4 oi Fig. 2, and

Fig. is a perspective view looking into the vshipping case after the same has been cut transversely, substantially on theplane of line 4-4 of Fig. 2.

Like reference characters refer to like parts in the different gures of the drawings, and the sections taken are in the directions indicated by the arrows.

The shipping case which, preferably, is made from paper or berboard is produced initially in a flat blank, shown in Fig, 1, longitudinally of which and at Aits central portion, are the side I, end 2, opposite side 3 and opposite end 4 in longitudinal alinement. At the free end of the side I there is a flapy5 and the blank'is creased trans,- versely as indicated by parallel lines 6 the full width of the shipping case blank. Similarly between the side I and end 2 are like creases 1; between the end 2 and the side 3, creases 8; and between the side 3 and the end 4, creases 9.

When the blank is folded about the creases 6, 1,

8 and 9, the sides I and 3 and the

ends

2 and 4 are disposed parallel to each other and the flap 5 may be bent within the outer edge portion of the end 4 and stapled thereto.

Alongside the bottom edges of the sides and ends I, 2, 3 and 4 are the bottom members of the shipping case. The section I0 extendsfrom the lower edge of the side I, section II from the lower edge of the end 2, I2 from the lower edge of the side 3 and I3 from the lower edge of the end 4.- A notch I5 'is cut in thev blank to define one' end of the ap 5 previously described and also a ap I4 which extends from the outer end of the section I0, the same creasing 6 being utilized for easy folding of the flap I4 as are used with the flap 5. The blank is creased longitudinally as at I6 to provide the division between the sides and ends of theA box and the bottom members. The blank is cut on the lines I1 and I9 to provide aps I8 at'the ends of the sections III and I2, similar in all respects to the flap I4, and in both of the sections II and I3, the material extends beyond the edges of the sections I0 and I2 in the form shown, providing tongues 20 which may be folded about the creases 1, 8, 9 and 9a. The section I3 at the end edge ofthe blank is cut on the lines Ila and I9a to make the part I3 symmetrical and identical in form with the part II.

When the case is set up the bottom sections I0 and I2 are turned inwardly from the lower edges pf the opposite sides I and 3, the free outer edges PATENT) ori-lcs of the bottom sections I0 and I2 coming together as shown in Figs. 4 and 5. The parts Il and I3 are likewise turned inwardly from the lower edges of the

ends

2 and 4 lying over the bottom sections I0 and |2. The various flaps I4 and I8 at the ends of the bottom sections I 0 and I2 are turned upwardly at the outer sides of the

ends

2 and 4 and arestapled thereto. The tongues 20 will be disposed at the inner sides of the sides I and 3 at the middle portions thereof and are turned upwardly, as best shown in Fig. 5 and, may be stapled to the adjacent sides I and 3. It is not absolutely necessary that these tongues be stapled but in many cases it is desirable and the structure lends itself perfectly to such stapling. I

It is evident from the foregoing description that a very strong reinforced bottom structure is provided. There is not only a double thickness of material but in a zone midway between the ends of the case the connection of the tongues 28 to the sides provides an exceedingly strong reinforcement which resists any tendency of the bottom to bulge or give, not only from the weight of the contents within the case, but due to any sudden lifting of the case which puts an addi.

tional strain upon the bottom.

'I'he upper and closure structure for the shipping case lies in the blank at the opposite side of the sides and ends I, 2, 3 and 4, longitudinal creases 2| defining the folding lines. A top closure section 22 joins with the upper edge of the side |.\-A section 23, to be folded downwardly within the end 2, joins with the upper edge thereof. A second top closure section 24 is joined at the upper edge of the side 3 and aysecond downwardly and inwardly foldingr-member 25 joins with the upper edge of the end 4, all having the equivalent of a hinged connection to said respective sides and ends on the creased lines 2|. 'Ihe top closure section 22 has a flap 26 in alinement with and in the same plane with the flap 5 and foldable about the creases 6, and with anotch 21 at the outer edge cut inwardly between the creased lines 6, thereby providing a tongue 28 which is substantially square in cross-section. The tongue 28 is foldable at right-angles to the plane of flap 26 about creases; 29 which extend the full length of the blank. The creases 29 divide the top section 22 from a projecting flange 30. At the inner end of the section 22 a like flap 26, notch 2l and tongue 28 are made by cutting the part 23 on the lines 3| and 32. Similarly the other top section 24 has endflaps 26 with tongues 28 provided by notches 21, there being a flange 33 projecting from the top section 24 similar to the flange 30; and the

members

23 and 25 are cut on the lines 3| and 32 and 3| a and 32a as shown to provide the structure described.

The

ends

2 and 4 of the shipping case each have a longitudinal slot 34 with closed ends cut therethrough for the entrance of the hands in lifting and carrying the case. Directly above each slot 34 is a vertical sl'ot 35 with closed ends across which the creases 2| pass'midway between the ends of said slots 35. Above each of the slots 35 in each of the members 23 and 25 a hand hole closing flap 36 is cut, the cut being at three sides, the remaining side being integral with the fiber or paper board material and substantially at the creases 29. f

With a structure as described, the flaps 26 are turned inwardly at right-angles along the creased lines 6, l, 8 and 9, the tongues 2B are then turned inwardly at right-angles to the flaps 26, after which the

flanges

30 and 33 are bent inwardly at right-angles to the

top sections

22 and 24, the ends of said flanges and the tongues 28 being stapled together. The

parts

23 and 25 are turned inwardly about the creased lines 2| so as to lie flat against the inner sides of the

ends

2 and 4, as shown in Fig. 3. In such position the upper free edge portions of the closures 36 cover the openings 34. The cover sections may be turned to closed position with the ends of the

flanges

30 and 33, to which are connected the tongues 28, received within the open upper ends of the slots 35. That is, when the

parts

23 and 25 are turned to the position illustrated in Fig. 3. the slotted portions at 35 are in effect doubled about the mid points of the slots, thereby providing at the upper edge of each end of the box an open slot to receive the flanges of the cover sections. It is evident, as illustrated in Fig. 3, that the hand hole openings 34, covered by the parts 36 have any light which would otherwise pass therethrough excluded, but that the flaps 36, will turn readily inward to permit entrance of the fingers in handling the shipping case.

'Ihe top structuredescribed is very practical and satisfactory in use. 'I'he top of the case is strongly reinforced, the ends of the casings are reinforced, light is excluded and the entire case, including the bottom structure previously described, is of a very strong character. 'I'he blanks for the boxes occupy little space in transportation. There is comparatively little stapling to b e done to set up the case when it reaches its destination. The flap 5 is stapled to the end 4, the flaps I4 and I8 are stapled to'the ends 2 and 4, if desired the tongues 2U are stapled to the sides I Aand 3 and the tongues 28 are stapled to the ends of the flanges 310 and 33. One staple only is required for each of the tongues 28, two staples foreach of the aps I4 and`|8 and preferably ve for connecting the flap 5 to the end 4, though four staples may be used very satisfactorily for the flap 5. Sixteen staples therefore are all that are required for complete fastening the various parts together. This reduces materially thenumber of staples which has previously been required in shipping cases designed to serve similar purposes.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
