WIT/VESSIS V THOMAS M. MOREWOOD, OF ELIZABETH, NEW JERSEY.

RIGID GONVEYER non mourns;

Specification of Letters Patent.

Patented July 20, 1915.

Application filed November 8, 1913. Serial No. 799,888.

To all whom it may concern:

Be it known that I, THOMAS M. Mounwoon, a citizen of the United States, and a resident of 135 Vestfield avenue, Elizabeth, New Jersey, and whose post-office address is No. 253 Broadway, borough of Manhattan, county, city, and State of New York,

have invented certain new and useful Improvements for Rigid Conveyers for Liquids, set forth in the followingspecification.

This invention relates to shipping packages or cartons for sending liquids and semiliquids such as milk, cream, butter, cheese, jelly, honey, and the like by parcels post.

The objectv of the invention is to combine a plurality of structural features so as to produce at little expense a single unitary package embodying indestructibility, hermetical inclosing, light weight, non-contamination of the substance contained and facility in packing.

Illustrative embodiments of the invention are shown in the accompanying drawings, in which like characters designate corresponding parts, which form a part of this application and in which Figure 1 is a side elevation with the ends in vertical section of one embodiment; Fig. 2 is an enlarged vertical section of the embodiment of Fig. 1 before the'outer shell has its end crimped; and Fig. 3 is a .vertical section greatly enlarged showing a spring metal clip for clamping the cap.

An inner tubular shell 1 is built up out of paper or like substance by any well known process such as winding or folding several laps over a mandrel. in any event tubular preferably greater in length than in diameter and may haw e any shape in cross-section but is preferably cylindrical. The stock of which the shell 1 is formed should be sterilized and disinfected, which may be accomplished satisfactorily by subjecting it to super-heated steam and the employment'of a suitable disinfectant such as sodium and calcium hypochlorite which is non-poisonous and leaves the shell odorless. In the formation of the shell 1 attention is paid principally to the production of a tough wall which will bend rather than crack. The inner part of this shell 1 is impregnated and lightly coated with a lining 2 of a substance impervious to the goods to be contained. Paraffin is suitable for this purpose. The shell 1 may be dipped when hot in paraffin-or when hot This shell is the melted paraffin may be brushed or sprayed on. This lining 2 should be more than a surface coating. It penetrates as well as coats the fibers at and near'the surface and fills all seams.

An outer tubular shell 3 is formed snugly v to it by friction or a suitable adhesive. This shell 3 is shown made up of spiral overlapping lays of cheap paper to make a shell of consid rable strength against collapse. It may have a thickness of wall much greater than that of the inner. shell 1. Its end rims l and 5 lap beyond the ends of the shell 1.

Disk- like caps 6 and 7 of sterilized and disinfected paper-board are stamped out so that their marginal contour corresponds to the outer cross-section of the shell 1 and fits into the projecting margins 4 and 5 of the outer shell. These caps (land 7 are lined and coated interiorlythroughout the entire extent of their inner surfaces as is the inner.

shell 1. The outer ends 8 and 9 of the shell 3 may then be crinip ed inwardly against the caps 6 and 7 to clamp them to the ends of the shell 1. The crimping machine should heat the margins of the caps 6 and to melt and seal together the inner coatings 10 and 2, and 11 and 2 as shown at 12 and 13. Beadings 11 and 15 of sealing wax or parafiin may be applied tothe joint between the crimps S and 9 and the caps (3 and 7. In practice the bottom cap 7 should first be applied. and clamped home. The carton is then filled and the top cap 6 is applied, sealed and clamped home. It may be desired to omit the crimp 8 for the top cap 6 and substitute the clip 16.

This clip 16 is a sheet metal. ring bent at an to inclose the shell 1 and may be secured angle 17 about the edge of the rim 4 and having spursv 18 forced into the body of the shell 3. On the inner face of the rim 4 this clip 16 has spring-fingers 19 sprung inwardly slightly. The cap 6 should be of such a size as to be forced in past the fingers 19 against the end of shell 1, where it is held by the fingers 19 which have sprung out to engage the outer face 20 of the cap 6.

l/Vhat is claimed and what is desired to be secured by United States Letters Pat-- ent is 1. A carton suitable forthe shipment of liquids and semi-liquids comprising an inner tubular shell of paper; disk-hke caps i for covering the ends of said inner tubular shell and having a marginal outline corresponding to the uter cross-section of said shell; a lining o fi meltable material impervious to the substance to be contained coating the inner face of said inner shell and the entire inner faces of said caps, the said coatings being welded together by melt ing at their meeting localities, an outer tubular shell of paper-board snugly inclosing said inner shell and lapping over the ends thereof; and means at the end rims of said outer shell for clamping said ca'ps firmly against the ends of said inner tubular shell.

2; A carton suitable for the shipment of liquids and semi-liquids comprising an inner tubular shell of paper; disk-like caps for covering the ends of said inner tubular shell and having a marginal outline corresponding to the outer cross-section of said shell: a lining of meltable material impervious to the substance to be contained coating the inner face of said inner shell and the entire inner faces of said caps, the said coatings being welded together by melting at their meeting localities, an outer tubular shell of paper-board snugly inclosing, said inner shell. and lapping over the ends thereof; and means at the end rims of said outer shell for clamping said caps firmly against the ends of said inner tubular shell, said means at one end comprising an in ward crimp of the end rim of said outer shell.

3. A carton suitable for the shipment of liquids and semi-liquids comprising an inner tubular shell of paper; disk-like caps for covering the ends of said inner tubular shell a nd having a marginal outline correshell; a lining of material impervious to the substance to be contained coating the inner faces of said inner shell and said caps; an

outer tubular shell of paper-board snugly inclosing-said-inner shell and lapping-over the ends thereof; and means at the end rims of said outer shell for clamping said caps firmly against the. ends of said inner tubular shell, said means at one end comprising an inward crimp of the end rim of said outer shell and at the other end a marginal metallic clip having inwardly directed spring fingers yielding upon the seating of said cap later to spring out to hold the rim of said cap.

'4. A carton suitable for the shipment of liquid and plastic materials, comprising an inner shell of tubular form, a gjslg s eparate from said shell and disposed iiarallel with and in close proximity at one end thereof, a lining impervious to the material to be shipped and engaging the inner surface of said shell and covering one face of said disk, said lining being provided with a peripheral portion of annular form extending between the periphery of said disk and the adjacent end of said tube, an outer shell encircling said inner shell, and means carried by said outer shell for engaging said disk and pressing the same toward the adjacent end of said inner shell.

In Witness whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
