HENRY OIPGENORTH, OF SHEBOYGAN, WISCONSIN.

PACKING-PAID.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed February 17, 1919. Serial No. 277,551.

To all whom it may concern:

Be it known that I, HENRY Orsnivonrrr, a citizen of the United States, and resident of Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Packin Pads; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in packing pads of that type comprising a filler of excelsior or similar compressible material inclosed within a suit able wrapper or casing.

Pads of this character are usually formed by machines which fold the wrapper material about the filler and deliver continuous stretches of padding which are subsequently cut to the desired lengths, thus leaving the packing exposed at the ends of the cut strips.

It is primarily the object of my invention to impart a finished appearance to pads formed in this manner, and to prevent the escape of the filler material from the wrapper.

More particularly, it is anobject to provide a most economical and eflicient arrangement for holding such pads in tubular shape for protecting bottles and the like.

With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts, as hereinafter more particularly described and defined by the appended claim.

In the accompanying drawings: 7

Figure 1 is a perspective view of a flat packing pad embodying my invention.

Fig. 2 is a perspective view of one end portion of a tubular pad, looking at the outside of its edge connection.

Fig. 3 is a perspective view of an end portion of cylindrical pad, looking at the inside of said connection. a

Fig. 4 is a detail transverse sectional view through the edge connection of a cylindrical pad on a plane indicated by the line 4-4 of Fig. 2.

Referring now more particularly to the accompanying drawings. there is shown a pad comprising the usual filler body 5 surrounded by the usual wrapper 6 which has its edges connected by a longitudinal seam which may be formed by a connecting strip 7 pasted to said edges, or may be formed in any other suitable manner, the connection of the wrapper being not material to my invention. This pad structure is cut from the continuous stretches formed by the usual pad making machine, and it is noted that in the structure described the ends of the packing body are exposed.

To afford a complete enveloping of the packing body, to present a finished appearance to the pad and to prevent loss of packing material, I provide end closure strips which are bent longitudinally to receive the ends of the pad between its sides, said sides beingpasted to the ends of the wrapper, as shown particularly in Fig. 1.

I thus, in a most economical manner, pro- .vide a pad wherein the packing material is completely inclosed to prevent loss thereof and the consequent objectionable litter in the use of the pad. When it is desired to provide a cylindrical pad, of the general type used for packing bottles and the like, the foregoing structure is preferably used, the pad being curved to effect the cylindrical shape, this curvature extending longitudinally of the closure strips 8 whereby said strips are disposed in opposition.

It has heretofore been the practice in connecting the longitudinal edges of a cylindrical pad of this nature, to provide connecting strips pasted to the inner and outer sides of the meeting edge portion, but in machines heretofore contemplated for applying said strips a serious difficulty has been experienced in procuring a proper relation of the edges of the connecting strips which are pasted together at the ends of the pad, with the result in practice that free paste surfaces are presented which would objectionably adhere to the object packed in the pad.

To connect the longitudinal edges of the pad in a manner avoiding the afore recited disadvantages, I provide a single connecting strip which is pasted to the outer sides of the meeting edge portion of the pad, the ends of said strip being bent about the ends of the pad and pasted as at 10 to the inner corner portions of the meeting edges. Thus I avoid a possible exposure of any paste surfaces du to slight displacement of the proper position of the connecting strip. and at the same time a complete end connection is effected. It is also noted that I avoid the necessity of providing an inner connecting strip, with the consequent labor entailed by its application.

What is claimed is:

A acking pad comprising a filler body of cushion material, a Wrapper structure disposed about the filler body, said filler body and Wrapper structure being bent in tubular shape to dispose the side edge portions of the Wrapper structure in abutting relation and a securing strip pasted to the outer faces of the side edge portions of the Wrap per Structure, said securin strip being greater in length than the iength of the Wrapper structure and having its terminal portions bent about the'ends of the Wrapper structure and pasted to the inner faces of the side edge portions of the Wrapper structure adjacent the ends thereof.

In testimony that I claim the foregoing I have hereunto set my hand at Sheboygan in the ounty of Sheboygan and State of Wisconsin.

HENRY OPGENORTH.
