Application May 10, 1939, Serial No. 272,891

3 Claims. (Cl. 20S-52) My invention relates to containers employed for packaging photographic roll iilm when sold or sent to be developed, and my main object is to provide a container which is suitable both for the spool of lilm as sold or exposed and for the reel of the iilm after it had been developed A further object of the invention is to provide a package containing a filler which retains the film spool in the proper position and against vibration or movement in the package.

A further object of the invention is to design the filler aforesaid to facilitate the deposit of the lm spool in the package and in a manner to be strong, hold its form, and be of light weight to save transportation and mailing costs.

A still further object of the invention is to design the said ller with means for seating the nlm reel against movement in the package.

An additional object of the invention is to construct the package simply and on a very economical basis.

With the above objects in view, and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Fig. 1 is a perspective View of the novel container;

Fig. 2 is a longitudinal vertical section showing the interior of the container with a film spool deposited therein, the spool being partly broken away;

Fig. 3 is a View similar to Fig. 2, showing the lm spool removed and a dot-and-dash line indication of a nlm reel;

Fig, 4 is a transverse vertical section through the center of Fig. 2 with the container closed and with an enclosed nlm spool positioned therein;

Fig. 5 is a similar section of Fig. 3 but with an open nlm reel positioned therein; and

Fig. 6 is a horizontal section on the line I- of Fig. 3.

Spools of roll-film as usually sold for amateur motion-picture use are placed in round boxes which are packed in cartons. After the user has exposed the nlm he replaces the box or spool in the carton and takes or mails the package to the proper agency to have it developed. When this has been done, the lilm is on a reel which is contained in a package of commensurate size, such package being mailed back to the user or held at the agency until he calls for it. In the novel embodiment I provide a package which is usable both to contain the exposed nlm and its spool during transport to the developing agency and to contain the developed lm and its reel when the same is returned to the user in a form to be mounted in the motion-picture projector.

In accordance with the foregoing, the container/ is primarily a pasteboard carton I0 of square form and extended with a cover ap II and side tabs l2 in the usual manner.

In order that the carton I6 may be adapted for the packaging of the film box I3, a fiat filler I4 of relatively thick pasteboard is employed. The filler is of a size to snugly t the interior of the carton I0 when -deposited therein, and has side wings Isa to fit in the end portions of the carton, the wings being cut back with medial recesses I5.

The liller Id is pressed with a D-shaped formation I6 which appears in relief in the channel or hollow ofthe filler. The formation I6 meets the filler roundedly on its inner side but has an enlargement Il on its outer side formed as a rim, the outer wall Ila of the enlargement meeting the ller I4 at the bottom. The sides Ilia of the formation I6 first have a bridge I8 between them, the side portions of the bridge meeting the iiller I4; then both the sides Ita of the formation I6 and the sides lla of the rim Il take gradual tapers ISU and I'Ib to meet the filler evenly near its outer edge. f'

With the ller I4 inserted in the carton It as indicated, it forms not only a reinforcement for the side wall Illa of the carton, but the wings It form a reinforcement for the end walls thereof. The inner contour or yspacing of the rim I'I provides a seat to receive the lm boX I3; and the formation I6 and bridge I8 provide a substantial seat for one face of the box, as is evident from Figs. 2 and 4. The tapered portion ISb of the formation facilitates the insertion of the lm box I3 into the package to occupy the position shown. The capacity of the carton I0 is so calculated that the inserted nlm box is snugly fitted between the formation I6 of the ller and the side wall Illb of the carton. The tabs I2 may now be turned in and the cover flap II tucked in to close the carton in the usual way. The front of side wall Ib of the carton has suitable address data, as indicated in Fig. 1, for the proper delivery or mailing of the package to the developing agency.

When the film has been developed, it is usually wound on a reel I9 suitable to be mounted in the motion picture projector. 'I'he reel is usually considerably larger than the original spool and is therefore returned in a different carton of commensurate size. In the present instance, however, this is unnecessary, as the original carton is of a sufficient size to receive the reel. Figs. 3 and 5 show the reel deposited in the carton. In order to do this, the reel is inserted in the manner of the spool in the previous instance, but is positioned between the rim l1 of the filler I4 and the side Wall lb of the carton. Also, the side portions of the reel are positioned in the recesses l5 of the filler wings I4, the ends Nia of such recesses forming abutments to prevent the reel from rolling or sliding out of the carton should the cover flap Il be insufficiently closed.

It will be evident from the above description that I have provided a package which renders a complete service for the user of amateur motion picture iilm, By means of the novel ller i4 the iilm box may be safely stored in the package or mailed to the user; also, the package affords the user a simple and safe carrier for the delivery or forwardingr of the exposed film to the developing agency. Further, the package is handy for use to return the developed lm on the larger reel, savingfthe cost of another package for this purpose. From the viewpoint of economy, the carton l is of the conventional, inexpensive type; and the ller M is a common grade of pasteboard, stamped and cut in one or two operations by machine, so that the added expense of the filler for the initial package is easily offset by the elimination of the second or return package from the service. Altogether, the improved package is an exceedingly simple, safe and handy medium for a modern and eiiicient nlm service in the amateur motion picture eld.

While I have described the novel roll lm container along speciiic lines, various minor changes and refinements may be made therein without departing from its principle, and I desire to consider all such changes and refinements as coming within the scope and spirit of the appended claims.

I claim:

l. A combined lm roll and lm reel container, comprising a. carton open at the top and having side, end and bottom walls, a reinforcing ller within said container in flat contact with one side wall, said filler having a snug fit between said end walls, an integral inwardly directed U-shaped projection formed on said iiller toward the opposite side wall, a second inwardly directed U- shaped projection formed integral with the outer marginal portions of said first projection and projecting inwardly beyond the same towards said opposite sidewall, said second projection terminating short of the opposite side wall of said carton to provide a space therebetween, as and for the purpose set forth.

2. The structure of claim l, and a horizontal rib integral with said filler, said rib projecting inwardly towards said opposite side Wall, said rib being ush with said iirst projection and connecting the legs thereof.

3. The structure of claim 1 and the free ends of the legs of both of said projections being beveled towards the open top of said carton.
