l i P PER. RECEP-TACLE.

Be it known that I, CHARLES. FRANCIS JENKINS, citizen ,of the United States, residing at Washington, in the Districtof Columbia, have invented certain .new and useful Improvements. in Paper Receptacles, of Which the following is a specification, reference being had therein to the accompanying drawing. l

Y In making boxes, usually of'paper, having interior and exterior tubular layers and provided with independently formed closures .often desirable to cut the inner layer or tube shorter than the other, so that its ends may serve as shoulders or stops for the subsequently inserted ends or closures. When, however, the inner layer'is very thin, the

An object of this invention is to avoid this evil without material expense, and at the end portions of the body, where a thinner sclosure may safely be used. This is done by crimping and bending inward in roughly conical form the end portion of the In the accompanying drawings, Figure 1 is an axial section of a closed cylindrical box embodying my invention; Fig. 2 is a plan or end view of the same box with the top cloeureremoved; Fig. 3 is a section similar to Fig. 1, showing a slight modifi-- cation. L

In these views,- A represents a cylindrical:

formed simultaneously, the method of forming not being here material. When the body has been formed, preferably plane, disks D are inserted in the projecting end portions. of the outer tube and pressed'down against the edges of the inwardly bent poi-- tions of the inner .tube completing the box. If the thin inner tube has considerable natural stiffness, the corrugated portions when given a proper angle add very materially to the lateral stiffness of'the ends of thebox and therefore the end disks may be made quite 'thin.

1 Boxes such as those thus far described are not suitable for liquids, but if the inner tube B, Fig. 3, has its end'faces made plane at E and parallel to. the end of the outer tube A, the closure D may be cc mented to such plane face, and if the whole for liquids. As suggested in Fig. 3, either novel construction may be used at one end only of the .box while the other end of the compressed tube may be closed by other devices, such, for example, as the flanged disk F.

What I claim'is: h 3 l. A'bOX body made up of an. outer tube be given a waterproof coating, it will serve of uniform cross-section and an inner tube closely fitting therein and having one end portion corrugated and bent inward at an oblique angle and its free 'marginat some. distance within the plane of the outer tubes end 2. A (paper box body consisting of an outer tube and a shorter inner tubeclosely fitting therein and having one end ortion carrled inward to form a conical rustu m terminating in a thin edge in position to meet a plane closure inserted in the end of the outer tube.
