3 Claims.

This invention relates to a strip of material for use in protecting beads, flanges, or the like, of containers such as barrels and drums during shipping and handling of the same, and this ap- 5 plication is a continuation-in-part of my applica tion Serial Number 47,220, filed October 29, 1935.

Steel barrels are frequently manufactured with integral beads extending circumferentially thereof to lend added strength and rigidity. These 10 projecting beads have been found to rub against each other since the barrels or drums shift relative to each other during shipment. A considerable amount of wear thus takes place on these projections and the containers are apt to arrive at their destination in an unsightly condition.

One object of my invention is toprotect these exposed beads by applying thereover a strip of material in the form of a band. Such a band also lends itself to decoration and advertising and may be very readily removed or renewed, if desired.

A further object of my invention is to provide a pre-shaped band of paper-like material such as cardboard or paperboard so that it may be used as above described.

Further objects of my invention will be apparent from the detailed description of the embodiments thereof illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a barrel having a preferred form of my improved protector strip in place.

Figure 2 is a vertical sectional view of the shaped paper strip taken on the line 22 of Figure 1.

Figures 3, l and 5 illustrate blanks for forming strips in accordance with further embodiments of my invention.

Figure 6 is a perspective View of a barrel provided with a modified protector strip.

Figure '7 is an enlarged top plan view of this modified protector strip.

Figure 8 is a sectional view of this protector strip taken on the line 88 of Figure '1.

Figure 9 is a perspective of a barrel showing a still further modification of protector strip in place, and

Figure 10 is a plan view on an enlarged scale of the protector strip shown in Figure 9.

In the drawings, the numeral l indicates generally a strip or band of cardboard or other paper-like material which has been pro-shaped by means of heat and pressure as described in my application S. N. 47,220 to provide an upwardly curved central portion I adapted to fit over the bead or flange of a barrel, and corrugated mar ginal portions l2 adapted'to lie against the side wall of the barrel on each side of the'bead thereof. Due to the corrugation of the marginal portions [2, the strips l0 tend to assume a generally 5 curved shape conforming naturally to thecurvature of a drum or barrel,

In applying the shaped strips to the beads of a container, the individual strips Ill may be fitted around the beads of a barrel [3 and the ends of the strips pasted together of secured in any other desirable manner. These bands will then be securely held in place due to their shape and may remain on the barrel until it reaches the ultimate consumer. If the strips should become torn or damaged they may be readily ripped off and replaced with fresh ones. Such strips add materially to the appearance of containers such as barrels and drums, as well as serve to prevent wear and preserve the surface of said containers. Such protection is an especially important fea-' ture when the containers are coated on the outside as with enamel or paint.

Figures 3, 4 and 5 illustrate flat blanks which may be readily formed into strips and bands for individual application to barrel beads and the like, as described above. The blank shown in Figure 3 has the marginal portions cut out as shown at M to produce a scalloped edge leaving tongues l 5 extending outwardly from the central portion it of the strip. This blank may be applied to a barrel bead directly or may be first shaped by rolls as desired. In either case, the central portion IE will be curved longitudinally of the strip drawing in the tongues l5 towards each other. I

Figure 4 illustrates another embodiment of my invention in which the marginal portions of the strip may be cut out as at IT, leaving a plurality of spaced transversely extending tongues I8. As the central portion l9 of the strip is curved these tongues will likewise be drawn in together to close substantially the openings I1.

According to a further embodiment illustrated in Figure 5, the marginal portions of this strip may be folded along the lines 20 and 2| so that when the strip is shaped these sections will form pleats taking up the excess material. The marginal portions of the strip may also, if desired, be slit transversely along the lines 20 to provide for overlapping sections to effect a similar result.

Figures 6 to 10 illustrate a difierent application of my improved protector strip, in which a single strip is used to cover two or more beads on a barrel l3. In the form of my invention illustrated 55 in Figures 6, 7 and 8, the strip 22 may comprise a relatively wide raised band 23 having marginal portions 24 which are preferably corrugated, although they may be varied in accordance with the marginal portions of the strips shown in the other figures, if desired. The central or main portion 23 of this strip covers the space or spaces between two or more of the flanges or beads on the barrel l3, andprovides adequate space for advertisement or decoration. In addition, such a strip may be readily made by a single operation in accordance with the method and by employing apparatus similar to that described in my prior application Ser. No. 47,220.

Figures 9 and. also illustrate a protector strip adapted to be placed over two or more flanges or beads of a barrel I3, but having a different marginal construction. The strip 25 is preferably pre-shaped with a relatively wide raised marginal portion 26. In this case, the marginal portions are cut away as at 21 leaving tongues 28. The tongues 28 are preferably strung on cords or wires 29. In this manner, the strips 25 may be removably applied to the barrels 13 by tying the ends of the cords 29 together after the strip has been placed around the barrel.

The terms used in describing the invention are used as terms of description and not as terms of limitation and it is intended that all equivalents of these terms be included within the scope of the invention claimed.

I claim:

1. A pre-formed band of paper-like material for protecting beads and the like on barrels comprising a central portion arranged to extend over and protect a plurality of said beads, marginal portions formed with a plurality of laterally extending longitudinally spaced tongues, and cords connecting said tongues for securing said band in place on a barrel, said cords extending longitudinally of said band and in spaced relation with respect to said central portion.

2. A pre-formed band of paper-like material for protecting a pair of spaced beads on a barrel comprising a smooth central portion of a width sufiicient to extend over and protect a pair of such beads, and marginal portions on each side of said central portion formed with a plurality of laterally extending spaced substantially parallel barrel contacting surfaces, said surfaces extending substantially normal to the longitudinal axis of said central portion, and said surfaces when the band is applied tothe barrel lying adjacent the outer side of a bead of the barrel and serving to secure the band on the barrel against relative movement thereof longitudinally of the barrel.

3. A pre-formed bandas defined in claim 2 in WILLIAM LOCKHART.
