INTEGRAL CARTON FOR PROTECTION OF FRAGILE ARTICLES Filed Oct. 27, 1948 3 Sheets-Sheet 2 INVENTOR.

Patented Sept. 23, 1952 UNITED srAlrss ra'rg OFFICE INTEGRAL CARTON FOR PROTECTION OF FRAGILE ARTIGLES I John F. Currivan, Dayton, Qhio Application October 27, 1948, SerialNo. 56,736

The object of the present invention is to provide an inexpensive integral carton construction, affording protection for fragile articles, as, for example, radio tubes, such protection heretofore having required tubes of corrugated board to encircle such fragile articles in cartons.

A further object is to enable the packing of tubes of various diameters in one size cartons.

A further object of the invention is to provide such an integral carton construction, adequately protecting the fragile articles and yet of such form that the carton can be successfully erected, loaded and both ends closed by conventional automatic cartoning machines.

The invention will be described with reference to the accompanying drawings, in which:

Fig. 1 is a perspective view of a closed carton embodying the invention.

Fig. 2 is a transverse section through the structure of Fig. '1 on the line 2-2.

Fig. 3 is a view similar to Fig. 2, showing the use of a modified form of carton 'blank,-which is shown in Fig. 9.

Fig. 4. is a view similar to Fig. 2 showing the use of the carton blank illustrated in Fig. 8.

Fig. 5 illustrates a carton blank as erected in Fig. 2.

Fig. 6 is a vertical section on the line 66, Fig. 2.

Fig. 7 shows the carton blank used in the structure of Fig. 10.

Fig. 8 shows the carton blank illustrated in Fig. 4.

Figure 9 shows the carton blank shown erected in Figure 3.

Figure 10 is a transverse sectional view of a carton erected from the blank of Figure 7.

Referring to the drawings and to the carton blank'o'f Fig. 5, it will be seen by-reference to Fig. 2 that when the blank is erected, it will provide an inner-partition l adapted to separate two fragile articles 2*, as shown in Fig. 2, or to receive single fragile articles, such as radio tubes, of various diameters, because of the flexibility of the inner flap partition I. The blank shown in Fig. 5 is formed with the usual side wall areas 3 and at each end is provided with short closure flaps d which will underlie, as customary, outer and final closure flaps 5 for the top and bottom of the carton.

At one side of the blank there is provided the usual side wall lateral extension 6 which will normally underlie and be glued to the opposite outermost side wall section. Integral with such side wall gluing section 6 is the flexible and pro- 9 Claims. ((31. 229-38.)

. Z V jectedflap-partition I, the latter usually being ofsuch width that when the blank is erected into carton form, as shown in Fig. 2, the said flexible flap partition will, at its free edge, abut one of the side walls and will extend in a straight line; It will be understood, however, that the flap may be wider so that in its erected position, the partition flap will be put under compression and forced to assume a curved formation within the carton.

When a radio tube or otherapp-ropriate fragile article is inserted into the carton, the side wall area thereof will engage and deflect the flap partition I to an extent controlled by the diameter of such fragile article and a tight articleenclosing carton will be provided, the latter preventing such movement of the enclosed article, as to contribute, in such'respect, to breakage. Also, in multipleshipping of'the cartons, they may be so arranged in the container thatthe flap partitions will hold the fragile articles so spaced from each other that breakage is avoided. Thus the large cartons holding a dozen or more of the individual cartons maybe of light construction and of much lower cost than those heretofore employed.

In the structure of Fig. 9-, shown erected in Fig. 3, the flap partition has been divided by a diagonal cut so that the flap partition has a major section 7a and an underlying minor section "I, which is-not separated from the section 6 in a score line, and thus forms a continuation of the section 6 lying flat against the side-wall 3. The carton, in other'substantial respects, is the sameas that of Fig. 5, although the end closure flaps are shown-notched at 53:. Such a carton may be'usedin two ways. Thus when the base of a radio tube, or other fragile article, is'of greater diameter than 'the upper structure of thetube, the score line 8 bounding the outerglue area for connection at the side walls in the erected carton, may extend, as shown-in Fig; 7, across both of the flap areas la and l, and when the carton is erected, the flaps will lie at different angles in the carton, as shown in Fig. 10. In Figures 3 and, 10, the upper portion of a radio tube'is indicated by the dotted line 9 as abut ting flap-section la, whereas the base area [0 of greater diameter maybe unsupported as shown in Figure, 3, or may abut the flap section I, as shown in Figure 10. It willbe apparent that a smaller article 2* may be supported in the carton of Figure-10 in'a manner similar to that shown in Figure 2. However, when the article to be insertedinthecarton'is-of such form as not to require the divisional effect of flap 1, the latter will not be scored on the line 8 beyond cross flap 1a, so that flap I will remain in full surface contact with the inner wall of the carton. The flap I thus maintains an even thickness from end to end of the body of the carton, when in its flat folded state, which is important in proper feeding from a stack of the cartons from the feed magazine of a cartoning machine.

In the structure of Figs. 4 and 8, the flap partition is inwardly bounded by the score line 8a: and is provided with a second intermediate score line H to provide two contiguous partition flap sections l2 and I3. When the carton is erected, the carton folds back on itself at the score line H like a tent, which arrangement centers the tube in the carton, keeping it from contact with all of the side walls with the exception of one. The blank in Fig. 8 as to the top and bottom closure flaps may be substantially similar to the construction shown in Fig. '7 and hence the same reference numerals have been used for such parts.

It will be understood that various modifications may be made in the form and arrangement of the elements constituting the embodiments of the invention illustrated in the drawings, without departing from the spirit of the invention. In some cases the areas left vacant by the action of the flap partition may be utilized for the reception of small units, as indicated at 2 in Figs. 2-4 inclusive but ordinarily such spaces will not be utilized.

As a further modification, and referring to the blank of Fig. 8, the flap partition sections l2 and I3 may be increased to four so that a diamond shape protecting flap partition formation will be provided within the carton when the latter is erected, the two additional fiap sections lbeing indicated by dotted lines in Fig. 4 at M and J5.

I claim:

1. A carton comprising side walls, end walls, a plurality of partitions of different lengths at- :tached to one of said side walls at a common .hinge line, said partitions being bent to extend inwardly of the carton and angularly of said side walls and of each other, the free ends of said partitions freely and slidably abutting one of said .side walls.

2. A carton comprising integrally connected side walls, one of said walls having an extension underlying a portion of an adjacent second side wall and secured thereto, said extension terminating at a hinge line, a first partition attached to said extension at said hinge line and extending angularly inwardly of said carton into free contact with the internal surface of said carton, and a second partition attached to said extension at said hinge line, said second partition being of different length than said first partition and extending along said second wall in full surface contact therewith.

3.
