There is a psychological obthe invention. The container, whichisdesignated 15 jection on the partof the average purchaser, generally by the reference numeral I0, is made however, to a paper container for milk and the from a singleblank l l of material which may be like in that such purchaser fancies that inasmuch either cardboard, heavy paper or other suitable as the cream content cannot be determined by material, the blank being generally quadrantal in inspection-ofthe container, the seller will necesshape..

One method of securing the lower wall Fig. 2 is a transverse horizontal'section taken of the container in place is illustrated in Fig. 4. 50 substantially midway between the ends of the Thebottom wall 20 is formed with a downwardcontainer; ly extendingflange 2| lying on the same plane as Fig, 3 is a broken transverse section showing the side walls of the container. After the blank a modification in the construction of the side wall has been formed into the shape of the truncated portions; cone illustrated in Fig. 1, the bottom wall is put in 55 place and the flangedportion 2|, together with the laminated side walls, are placed in a suitable machine which forms the inwardly disposed,annular recess 22, which firmly secures the bottom wall in place. If desired, a suitable amount 01 adhesive may also be used to further secure this lower Wall. At the upper end of the container an inwardly disposedannular recess 23 is also formed, which annular recess serves as a seat which is indicated at 24 for the top closure disk, which is not shown.

In Fig. 6, the side walls of the container are formed with alternate raisedareas 25 and depressed areas 26, which latter are formed with apertures 2'! and in this instance the transparentflexible liner 28 is placed within the container af-' ter the corrugations or ribs have been formed and merely engages the inner surface of the container adjacent to the apertured areas. This type of construction presents a somewhat diiferent appearance from the container shown in the preferred embodiment and may be successfully used as a container for dry or powdered materials as distinguished from liquids.

The preferred embodiment of the invention is of considerably greater depth than width and accordingly the ribs are vertically disposed. In many instances, however, a more shallow container is desired for such materials as cheese, butter and the like, and in this case, the ribs will be annularly rather than vertically disposed.

A container of this type is illustrated in Fig. '7

and is indicated by the numeral 3|. The outerside wall portion 32 is formed withaperture 33 and a plurality ofannular ribs 34. The container is likewise provided with aliner 36 of transparent material.

What I claim is:

1. In a container of the class described, the combination of an outer wall constructed of substantially flexible fibrous material and an inner wall adhesively joined thereto, the inner wall being made from a sheet of flexible, transparent cellulosic material, the outer wall having a plurality of spaced apertures therein which are in substantial alignment vertically, the walls of the container having a plurality of spaced vertical ribs disposed between the apertures in the outer wall, and a bottom closure secured at the lower end of the container. I

2. A substantially cylindrical container of the class described, comprising in combination, an outer wall constructed of substantially flexible fibrous material and an inner wall adhesively joined thereto, the inner wall being made from a sheet of flexible, transparent material, the outer wall having a plurality of vertically and annularly aligned spaced apertures therein, the walls of the container having a plurality of outwardly disposed spaced ribs positioned between the apertures in the outer wall, and a bottom clo sure secured at the lower-end of the container.
