This invention relates to a filler or had for use 1 Claim. (o1. 2294.2)

the container against upward, end and side motion and at the same time absorb the shocks to which the article is subjected when in transit.

A further object of the invention resides in forming the recessed wall of the filler of a double thickness of material so the edges defining the recess which contact the article will have added.

strength.

Another object of the invention resides in forming the recess in the wall of the filler by a cut-out portion which is designed to fold inwardly when the filler is erected and yet permits the filler to be folded flat When not in use for convenience in shipping and storing.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a sectional view of a carton looking down on the top of the fillers in packing position,

Fig. 2 is a fragmentary sectional view of a carton looking at the end of the filler,

Fig. 3 is a fragmentary section of a carton looking at the inner side of the filler,

Fig. 4 is a cross sectional view of the filler,

Fig. 5 is a perspective view of the filler, and

Figs. 6 and 7 are plan views of the blank of material for forming right and left side fillers.

In the drawings wherein for the purpose of iilustration a preferred embodiment of the invention is shown, the numeral 5 denotes in general the filler or pad which is formed from a single strip of fiberboard or other suitable material 6, as shown in Figs. 6 and '7. The strip of material is provided on one side with transverse score lines or creases l at spaced intervals to form sections adapted to be folded to form a rectangular four sided structure with the end sections of the strip disposed in overlapping relation to form a side wall 8 of double thickness. The opposite side wall 9 and top and bottom walls iii and l! are formed of a single thickness of material. The overlapping end sections forming the side wall 8 may be stapled together as at l2.

The end section l3 forming the inner layer of the side wall 8 is cut-out to form a notch It in the free edge of the section. The opposite end section l5 forming the outer layer of the side wall 8 is provided with a cut-out panel H5 inwardly from the free edge, formed by spaced parallel slits H which extend into the section l8 forming the bottom wall II. The panel it at each end is provided with transverse crease lines l9 formed on the same side of the material as the crease lines i, while the opposite side of the panel, intermediate its ends, is provided with a transverse crease 20 which permits the panel to fold inwardly through the notch M of the inner layer of the side wall 8 when the filler is erected to form a recess 2| in the side wall having a back Wall 22 and top wall 23 but which is open at the bottom, as clearly shown in Fig. 5.

It will be seen that when the section I5 is folded at right angles to the bottom wall II the panel is will automatically fold inwardly and when engaged in the notch I i of the section I3 interlocks the end sections together to form a side wall of strong sturdy construction. The filler when erected is placed in the corners of the carton or container 24 with the recessed side wall 8 facing towards the inside to receive the marginal edge of the article to be held. A right and left filler is necessary for each side of the article to be held and are formed from the strips shown in Figs. 6 and '7, respectively.

In use the filler is inserted in the carton after the article is disposed therein. A filler is placed in each corner of the carton with the side wall 9 in contacting relation with the end wall of the carton and each. filler is of such length that the ends abut the side walls of the carton. The side wall 8 faces inwardly and the recess 2! formed therein is adapted to receive the marginal edge of the article to be held, as shown in dotted lines in Figs. 1 and 2. With the marginal edge of the article disposed in the recess the filler serves to secure the article against upward, end and side motion and also absorbs the shocks to which the article is subjected while in transit. The panel It automatically folds inwardly to form the recess in the side wall when the filler is erected and permits the filler to fold fiat when not in use.

Having thus described my invention, I claim:

A filler for shipping cases comprising a blank of fiberboard divided by transverse score lines into sections, one end section having spaced parallel slits extending longitudinally of the blank from a point adjacent its free edge to a point within the next adjacent section to define a panel foldable at each end and intermediate its length, a notch formedin the opposite end section extending from its free edge to a point adjacent the next section, said notch being of a Width sub stantially the same as the panel, the sections of the blank being foldable to form a rectangular frame having the end sections disposed in overlapping relation with the panel folded inwardly through the notch to form a recess in the side of the frame and operating to interlock the end sections together.

WILLIAM E. TURNER.
