2 Claims. (Cl. 229-51) This invention relates to a readily openable use with photographic films, I have so described package and a method of making the same. it.

One object of my invention is to provide a In accordance with Fig. 1, a completed packpackage with a rip-cord which can be readily age is shown as consisting broadly of an outside opened. Another object of my invention is to cover box I and an inside telescoping box secprovide a package composed of several sections, tion 2.

Obvious a re are many brought together cutting off the stripping and other articles which can advantageouslybeplaced rip-cord. The operator then tears oil the end in a package which can readily be opened, but of the stripping material so that the rip-cord 6 since my invention is particularly adapted for projects from the end, as shown in Fig. 4. 5

around the periphery, as shown in Fig. 5, the end of the cord and the stripping material 33 project down below the bottom 20 of the box Bl, as shown in Fig. 5. The operator then folds that portionof the stripping which extends below the bottom 20 up against the bottom wall of the box Bl, as indicated in Fig. 6, where the stripping 83 has been partially folded 'over at 35 against the bottom of the box. In performing this operation the operator quickly wipes down the end of the ripcord 6 against the bottom of the box and since this cord has been in contact with a portion of the gummed stripping which has been previously torn oil, as above described, a slight amount of adhesive remains on the cord. Thus the cord will lie fiat against the box, as indicated in Fig. 6.

With the box Bl equipped with this stripping and with therip-cord, the completed package can be assembled in the usual manner without in any way taking more time than is ordinarily necessary for assembling a package of this type.

Thus, if the package should be similar to a package in common use for shipping photographic films, the films may be contained in the package F, shown in Fig. 2, and this package may be placed in the box B2. After being placed in box B2, this box with the film package is telescoped in the box Bl, which, as above described, has already been provided with the rip-cord. The box BI is then telescoped into the box 133 which forms the cover box, and then these parts may all be assembled by placing on a second piece of stripping 3, as indicated in Fig. l, and folding the lower edge of this stripping over the bottom 20 of the box Bl to hold the parts in completely assembled position.

As above explained, the end 6 of the rip-cord was lightly attached to the bottom 20 of the box Bl by means of adhesive, so that the last stripping operation is performed without the necessity of positioning the rip-cord at all.

- Moreover, when the parts have been assembled into a complete package, it is a simple matter to locate the end of the rip-strip 6 to open the package. This rip-stripmay be pulled so as to tear through the comers 9 of the stripping 3 which has been folded over at to hold the package sections together. By pulling out on the ripcord 6, that portion of the cord 1 which lies around the periphery of the box Bl will pull down between the sides of the boxes BI and B3, causing the stripping to tear out and permitting the box B3 to be removed from the box Bi very easily.

While I have shown my rip-strip 1 extending around the entire periphery of the box Bl, it is quite obviously a simple matter to extend this stripping a less distance if desired. For instance, if it should be desirable to have a box composed of two sections hinged along one side, the rip-strip r 8,058,599 When the box has been completely stripped should be placed around only the remaining three sides so that the fourth side will remain covered by the stripping which may be of material 01 sumcient strength to form a hinge.

Ordinarily, it has been quitedimcult to apply a rip-strip to a multiple section box because of the difllculty of properly locating the rip-strip and, at the same time permitting a rip-strip to be attached in a proper location without a separate operation and without too great expense. As will be obvious from the above description, I have provided a method which adds only very slightly to the cost of a box, since an operator can add the rip-strip with the usual stripping with only'very slight additional time for the operation. Moreover, after the rip-strip has been applied, it is not only properly located with respect to the various boxes forming the package, but it also lies flat against the box to which it has been attached so that it does not interfere with the future operations of loading the box.

This is particularly important in loading photographic film because such film is always loaded in a dark room. Some films, such as Panehromatic, must be loaded in total darkness and it is therefore necessary to have the loading operation a simple one. If there should be a loose or free end of a cord used fora rip-strip, it would be diflicult, if not impossible, to properly place such a cord in assembling the package in total darkness. When the rip-cord is definitely located by a light gluing on the bottom of the box, this difficulty is overcome and the box sections can be handled quite as freely as when the rip-strip is not present.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. In a package comprising, in combination, two telescoping boxes including an inner box and an outer box, a strip attached solely to said inner box, a rip-cord attached to the inner box beneath said strip and having an end projecting to one side of the strip, said outer box being separately stripped to the inner box with said cord end projecting outside of the stripping, whereby the stripping holding the boxes together may be readily separated.

2. A package adapted to be filled comprising. in combination, an inner box and an outer box, a strip attached to said inner box only about its periphery, a rip-cord fastened to the periphery of said box by said strip and having an end projecting a distance from said strip, said outer box being adapted to receive the inner box in telescoping relation, said rip-cord end projecting from said strip a distance sufilcient to extend out between the two assembled boxes, whereby a separate strip may be applied to hold the boxes together to only partially cover said rip-cord end.
