Patented Nov. 14, 1933 UNITED STATES PATENT OFFICE 10 Claims.

This invention relates to improvements in containers and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

Containers are ordinarily made from either wood, metal or paper according to the commodity for which it is to be used in its intended purpose. For the lighter commodities such as certain foodstuffs, containers of paper or fibre may be used to advantage.

However, certain commodities require stronger containers and in this instance boxes, kegs and barrels made of wood are employed and sometimes such containers are made entirely of metal.

While each of said kinds of containers may have its advantage when used for a particular commodity it has innumerable disadvantages. For instance, containers for heavier commodities must, of course, have greater strength. Ordinarily heavier stock or material is employed so that the cost of manufacture as well as cost of shipment is increased in proportion.

The primary object of the invention is to provide a container especially adapted for the heavier commodities, which container is so constructed as to have all of the advantages of the materials now employed therefor without the usual disadvantages which are inherent therein.

Another object of the invention is to provide a container which though light in weight, is strong and durable, which may be shipped to the user in knock-down form for easy assembly as required, thus reducing shipment costs and which may be produced at prices competitive withv those of containers as now used. 1

Still a further object of the invention is to provide a containerof this kind having a composite vside wall structure made up of a, metallic sheet covered on both sides wtih non-metallic sheets, portions of the metallic sheet being flanged over upon one of the non-metallic sheets to not only protect the marginal parts thereof but also to stiien the entire structure.

Still a further object of the invent/ion is to provide a simple and eilicient method of making the containers which may be readily carried out by unskilled help.

These objects of the invention together with others as well as the many advantages thereof,

will more fully appear as I proceed with my y speciflcation.

Fig. 12 is a transverse vertical sectional view through the same on an enlarged scale as taken on the line 12-12 of Fig. 11.

Fig. 13 is a view similar to Fig. l2` after parts of the top and bottom margins of the blank shown in Figs. 1l and 12, have been turned over to form a partly finished flange thereon.

Fig. 14 is a View similar to Fig. 13 after said margins have been again turned over to form the finished flange therefor.

i. Fig. 15 is a vertical sectional View also on an enlarged' scale, through an end portion of a container embodying a modified form of the invention.

Referring now in detail to that embodiment of the invention illustrated in Figs. 1 to 10 inclusive of the accompanying drawingsz-l indicates as a Whole a blank from which the body of one form of my improvedl container is made. Said blank comprises a core of sheet metal 2 of the desired area or shape and to each side of the same is xed in any suitable manner, inner and outer non-metallic sheets or coverings 3 110 and Il respectively. Said non-metallic sheets or coverings are each of an area smaller than that of the metallic sheet to leave top and bottom margins 5--5 and end margins 6 6. These sheets, of course, will have a length and width corresponding to the height and circumference of the container to be made. For the core, I may use metallic sheets which have vimperfections therein or are more or less rusty or are in such other condition that they cannot be sold as first class sheets.

For the inner and outer non-metallic sheets or coverings I iind that jute stock paper will well serve the purpose and preferably the same are secured to the core by an adhesive of any suitable kind. In this instance, I have referred to said non-metallic sheets as inner and outer but this is only for convenience and is used to designate the positions these sheets occupy in the finished container; that is, upon the inside and the outside thereof. Again I have stated that saidinner and outer sheets are of paper but this is to be considered as by Way of" example only because as it is apparent other materials may be used having characteristics which makes them adaptable for the purpose.

With a blank such as shown in Figs. 1 and 2, I turn the top and bottom margins 5--5 of the core 2 or metallic sheet over upon the outer nonmetallic sheet d, along lines disposed in the planes of the top and bottom edges of the

sheets

3 and 4 to form a flange 5 (see Fig. 5) along the top and bottom of the blank. These flanges overhang and tightly engage the similar margins of the outer non-metallic sheet a and thus protect said margins against tearing in use.

I then turn the end margins 6--6 of the core or non-metallic sheet `over upon but not tightly down upon the outer non-metallic sheet l1, along lines as defined by the edges ofsaid last mentioned sheet to there provide hook flanges '1 -7 as best shown in Fig. 4. The blank thus far described, though made of buta thin sheet metal core with inner and outer paper coverings, is materially reinforced in strength and is somewhat stiiened by the flange constructions described.

The blank is now ready for forming into body shape. Such a blank is rolled in a direction parallel the flanges 5'5' to impart a somewhat curved or circular shape, with the non-metallic sheet 3 on the inside thereof. thus rolled, the two ends bearing the hook flanges '7 7 may be readily brought into engagement with each other. While holding said ends together temporarily, in the condition shown in Fig. 7, I apply a locking strip 8 thereto. Such a strip which comprises an outer wall 9 and inwardly facing inner anges 10-10 is slipped upon the now adjacent hook fingers 7--7 from one end as best shown in Fig. 6.

When the locking strip is in place, the flanges 1.0-10 will be engaged under the hook iianges "Z-J? and pressure is then imposed upon said strip which flattens down the flanges thereof so that the two ends of the blank are securely locked or held against separation. Thus there is provided a tubular body such as is shown in Fig. 6, which is circular in cross sectional shape. It is apparent that should other cross sectional shapes be desired, such as rectangular, hexagonal, octagonal and the like, the blank shown in Fig. 3 could readily be creased to provide such shapes without departing from the spirit of the invention. The circular shape of body described is With the blank"` ipsaovs therefore to be considered merely as illustrative of but one form in which it is possible to produce irr my improved container.

With a tubular body as thus far described, are associated closures 11-11, one for each end which closures are preferably but not necessarily of the same construction I find it convenient to make such aclosure in the form of a wooden plug like body, having an inner portion 12 of an axial length greater than that of the body flanges 5-5, and of a diameter approximating the inside diameter of the body, and an outer portion 13 of a shorter axial length but of a diameter approximating the outside diameter of the body. With such a closure it is apparent that an annular shoulder 14 is provided between said

portions

12 and 13. On the outer surface of the closure I provide a sheet of paper 15 that not only acts to finish off the'closure but also protects the closure against moisture which might split and damage the same.

I apply one closure to one end` of the body by inserting the portion 12 into said head until the shoulder 14 engages upon the extremity of said body as best shown in Fig. 9. I then drive suitable nails or brads 16 through the body into part 12 of the closure. Preferably these nails or brads are positioned as close to the edge of the associated flange 5 as is convenient. Thus one closure is provided for one end of the body of the container. The container is now ready for lling with the desired commodity from the other end which, of course, is still open after which said end is closed by another closure l1 such as just above described.

A container as above described is indeed strong and rigid and will amply withstand the rough treatment itvreceives in use when loaded with a fairly heavy commodity. One of the uses for whichy the container above described is especially adapted is for the shipment of welding rods and the container amply withstands the great strain thereof without opening up or denting. In this respect it is also pointed out that it does not sweat so that the rods remain in their original new condition without rusting until the container is opened. No matter how long such containers remain in storage, their contents remain unchanged. Because of the inner non-metallic sheet 3, the commodity cannot come into direct contact with the metal sheet or core.

My improved container is flexible so far as manufacturing problems are concerned and for the much heavier commodities where heavier containers are desired the same may be produced in a number of diierent ways. For instance, the core may be made of heavier metallic sheet stock and the same non-metallic sheets before mentioned may be used in connection therewith or the same metallic sheet as first described may be used for the core and a heavier paper sheet may be used for the inner and outer coverings, or said coverings may be made up of one or more plys. In Figs. 1l, 12, 13 and 14 this last mentioned arrangement is shown and will now be described.

In Figs. 11 and 12 the metallic sheet or core 18' is shown as provided with inner and outer non-metallic sheets or coverings 3SL and ia respectively, each comprising a plurality of superposed, adhered together plys leaving the margins 5a and 6a as before. A portion of each margin 5&-58 is bent over` upon itself to form a double thickness iiange 5b as shown in Fig. 13 after which said double thickness flange is turned outwardly and over upon the associated margins of the plys constituting the outer covering 4a. Thus a' much stronger as well as a somewhat heavier container may be made.

In Fig. 15 is illustrated a further modified form wherein 1b indicates the metallic sheet or core and 3b and 4b indicate the inner and outer non-metallic sheets or coverings therefor. In this instance, the marginal part of the metallic sheet is of such width as to be folded over to provide adouble thickness flange 1'? overhanging the top margin of the inner non-metallic sheet 3b and a single thickness flange 1'?a overhanging the top margin of the outer non-metallic sheet 4b. Thus a portion of the non-metallic sheet is employed to overhang the top margins of both non-metallic sheets so that a strong stiff construction is provided for the container end so that it cannot be easily misshaped.

From theabove it is apparent that the improved container is flexible. so far as its manufacture is concerned as it is open to a number of variations. Thus the container may be made to meet the requirements of any commodity to be shipped therein.

Again the component parts of the container may be shipped direct to the user with the blanks either in the flat condition or rolled to the desired approximate curvation for easyy assembly. Thus shipping rates and space as well as storage space is materially reduced with a resulting saving and the containers may thereafter be readily assembled as' the occasion demands. The improved container has the advantages of all paper, wood or metal containers withoutthe disadvantages thereof and can be manufactured at competitive prices with any or all of them.

While in describing the invention I have referred in detail to the form, arrangement and construction of the several parts thereof as well as to the manner in which it may be made, the same is to be considered merely as illustrative so that I do not wish to be limited thereto except as may be pointed out in the appended claims.
