Paper-tube package

Application filed April 14,

This invention relates to paper tube packages and is particularly adapted for packaging continuous tubes, such as blasting tubes.

£· I provide a paper tube package having an open center, a portion of the tube adjacent one end thereof departing from the regular windings and projecting into the open center. With this form of package, io access to the inner encl of the tube may be easily had, whereby lengths of tubing may be withdrawn from the interior of the package, as required, without disturbing the outer wrapping thereof. This is particu15 larly desirable in a miner’s blasting tube package, since the package is subjected to considerable handling and usage before it has been entirely consumed, and it is highly advantageous to provide a package which 20 will not unwrap or lose its tight wound character at any time.

I further provide for sealing the outer end of the package without resorting to a separate sticker, by utilizing the binding 25 strip which forms a part of the tubing.

In the accompanying drawings illustrating a preferred embodiment of the present invention,

Figure 1 is a side elevation showing the so manner in which a tube package is formed according to my invention; and

Figure 2 is a perspective view of a completed package.

In the illustrated embodiment of the in35 vention, there is shown a blasting tube package formed from a blasting tube made of a paper strip 3 formed into tube form and having an adhesive strip 4 over' the same. This sealing strip may be provided 40 with graduations 5, as set forth in the copending application of George S. Clark. Serial No. 535,643, filed February 10, 1922.

In forming a tube package, the end 6 of the tube is projected between a pair of 45 blocks 7 mounted on a rotatable head, and the head is turned with the tube under suitable tension, resulting in the formation of a series of windings 8, one over the other, until the package is of the desired size.

To secure the outer end of the tube, the adhesive strip 4 is extended beyond the outer end of the tubing 2, as clearly shown in Figure 2, and is secured to the adjacent wrap of the package·.

1924. Serial No. 708,230.

It will be noted that the finished pack- 55 age has an open center with a portion of the tubing projecting across the same. It is thus an easy matter for the miner to grasp this projecting portion and pull out the inner end of the tube; whereas, with the old style package, it was sometimes extremely difficult to locate the inner, end and as a result the outer label was frequently torn and this resulted in an unwrapping of the entire package. Moreover, the use of the ^ι;.’> open center eliminates the sharp bends at the ends of the package, which sometimes cause the adhesive strip 4 to separate from the tube, thus resulting in an imperfect blasting tube.

I provide a blasting tube package wherein the inner end is readily accessible for unwinding and-with a simple and adequate sealing means for the . outer end of the tube. ⁷⁵

While I have illustrated the preferred embodiment of the invention, it will be understood that it is not limited thereto, but may be otherwise embodied within the scope of the following claims. ⁸⁰
