' Referring in greater detail to the drawing, a

The inherent character of transparent cellulose in sheet form, as usually employed to make containers, is light in weight and delicate in texture. While it is tough and capable of resist- 5 ing strain, it is without perceptible grain and tears easily in any direction when the tear or out has once been started. Considerable dimculty is encountered in the manufacture of plicated and'creased containers because often the film texture is injured and its resistance is weakened in the process or making the folds and creases. The same difliculty, in a varied degree,

is experienced with thin sheets of opaque or semitransparent papers. 1 Y

It is an object of this invention to produce a container of transparent cellulose film or of other thin paper that has no sharp folds or creases.

A more particular object of my invention is to provide a container of transparent cellulose film, or of similar thin paper, that will stand erect and open when empty.

- My invention consists of a combination of a heavy paper or cardboard cup having a flange or wall 01' about one quarter or an inch or more in height and a tube of transparent cellulose film or of similar thin paper. The cup is in- I serted into one end of the tube so that the edge of the tube is flush with the bottom of the cup.

'Ihe'tube is fastened to the cup with adequate 3o adhesive, thus forming a cylindrical receptacle.

with the above and related objects in view,

my invention consists in the details of construction and combination of partsathat will be hereinafter fully described and the description will be more readily understood when it is read in ccgiljlfinction with the accompanying drawing in Fig. 1 is a perspective view of the complete container embodying my invention.

Fig. 2 is a perspective view 01! the heavy paper or cardboard disc which forms the base of my improved container.

Fig3 is a perspective view of the cylindrical transparent cellulose film or tube.

Fig. 4 is a fragmentary sectional view or my complete container.

cylindrical transparent cellulose fllm or sheet of cellophane, generallydesignated as a, is formed into a hollow tube by gluing two overlapping parallel edges of the film or sheet together. However, a seamless tube may be used.

A. container base, cup, or drum, comprises a heav-ypaper or cardboard cup having a disc-like member b and a peripheral flange 0 turned at right-angles to the disc-like member b. The base or cup is; inserted into one endof the tube so that the edge of the tube is flush with the disclike member b of thecup. The flange of the base interflts with the lower interior surface of the cellophane tube, and the base and tube are securely fastened together by means of suitable adhesive. sifting, air-tight and non-transparent. Thus, the fragments and. sediment of the container contents are shielded from view. It should be observed that the entire container will stand erect and open when empty.

I am aware that, prior to my invention, cylindrical packages .have been made of transparent cellulose film and of other thin paper sheets and therefore I do not claim a cylindrical con- This container bottom isnonofsubstantially greater weight than the cylindrical container film so that the device will stand erect, and said interfitting and flanged disc memsifting, air-tight, and non-transparent.
