1 CONTAINER Filed Sept. 21, 1920 Patented 6, 1923.

JOHN W. DARLEY, JIL, OF BALTIMORE, MARYLAND, ASSIGNOR TO CHARLES S. COHEN, OF BROOKLYN, NEW YORK.

CONTAINER.

Application filed September 21,3920. Serial No. 411,822.

To all whom it may concern:

Be it known that 1, JOHN W. DARLEY, J r.,

a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Containers (Case A) and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to containers for tooth paste, shaving creams, cold cream and for any other semi-liquid substances.

Among the objects of my invention are To provide a container which shall be artistic in appearance and which shall not be deformed in use.

To provide a container which can be readily filled and sealed but which will deliver any desired quantity of the contents thereof and shut off the delivery.

To provide a container having means for effectively preventing creeping of the contents after {the delivery is shut off.

To provide a container which can be readily formed by the use of simple tools.

In carrying out my invention I make use of the ins'trumentalities illustrated in the accompanying drawings, in which Figure 1 is a side view of my improved container partly in section.

Fig. 2 is an enlarged sectional view of the upper portion of Figure 1.

Fig. 3 is a view of Figure 1 looking in the direction of the arrow 3 in said figure.

Fig. 4 is a view of the parts shown in Fig. 1 with the closing cap removed.

Fig. 5 is a view of some of the parts shown in Fig. 2 looking in the direction of the arrow 5 in said figure.

In the drawings 5 represents a casing which may be formed of any approved material having the bottom 6 crimped at the lower end thereof. The upper end of the casing 5 is formed with the enlarged portion 7 having the flaring upper edge 8.

The frustro-conical end 9 is formed inte- 50 grally with the cylindrical flange 10 and the latter fits snugly within the enlarged portion 7. Through the frustro-conical end 9 projects the cylinder 11 having the slots 12 and terminating in the threaded end 13 in the 55 end of which is formed the lenticular slot 14.

The cylinder 11 is formed integrally with the frustro-conical portion 15 between which and the frustro-conical portion 9 is mounted the paper washer 16, the purpose of which is to prevent seepage of the paste'between the frustro-conical end 9 and portion 15.

A cylindrical hole 17 extends throughthe.

cylinder 11 and extension 13 to the lenticular opening 14 and a slot 18 is formed in the cylinder 11 for the reception of the head 19 of the screw 20. On the lower end of the screw 20 there is threaded the plunger 21 which may be of any approved construction and is shaped to closely approach the inner surface of the frustro-conical portion 15.

The operating cap comprises the knurled cylindrical portion 22 and the frustro-conical portion 23 near the juncture of which is a bead 24 the inner surface of which embraces the flaring upper edge 8 and prevents displacement of the operating cap from the container.

The frustro-conical portion 23 is provided with projections 25 which fit in the grooves 12 and thus lock the operating cap to the cylinder 11, and since the slot 18 in the latter embraces the head 19 of the screw 20, it is evident that revolution of the operating cap will produce revolution of the screw 20. The cap 26 is screwed upon the threaded extension 13 to close the slot 14.

In filling my improved container, the screw 20 and piston 21 are to be placed therein as shown. The paste is then to be placed within the container and the slot 18 within the cylinder 11 is to be placed to embrace the head 19 of the screw 20. The paper washer 16 is then to be laid upon the frustro-conical portion 15 and the cylindrical flange 10 of the end 9 is then to be placed within the enlarged portion 7 of the casing 5 and forced to the position shown in Fig. 2. The projections 25 are then to be placed within the slots 12 of the cylinder 11 and moved downwardly until the bead 24 embraces the flaring edge 8. The cap 26 can then be screwed in place and the container is ready for shipment.

IVhen it is desired to use the container, the operator unscrews the cap 26 and then holding the casing 5 in his left hand he applies the thumb and forefinger thereof to the knurled portion 22 of the operating cap and moving his thumb upwardly and his forefinger downwardly, he turns the operating cap' in the direction of the arrow 27 in Figure 1, thus causing the piston 21 to move upwardly, and forcing some ofthe paste out through the lenticular slot 14.

This effect obtains because the friction between the casing and the piston prevents the latter from turning, and the end of the screw 20 merely restsagainst the inner surface of the bottom 6.

When a suiiicient quantity of the paste has been ejected, the operator then reverses the direction of movement of his thumb and forefinger and turnsthe operating cap in a direction pposite to the arrow 27 thus causing the piston 21 to move slightly toward the bottom 6 and relieving its pressure from the paste within the container, thus efl'ectively preventing creeping of the paste through the slot 14:.

The cap 26 can then be applied to container.

Thus it will be seen that I provide a simple, cheap and effective container, capable of easy filling and preserving its artistic appearance while in use.

I claim 1. The combination with a casing, of a piston having frictional engagement therewith, a screw threaded in said piston, an end fixed in said casing, an operating cap rev-. olubly mounted on said casing and a member extending through said end and having operative connection with said screw and cap'and an eduction passage to the interior of said casing.

2. The combination with a casing, of "a piston having frictional engagement therewith, a screw threaded in said piston, an end fixed in said casing, a member extending through said end and having a flange parallel with said end, a sealing washer between said end and flange, a passage through said member, an operative connection between said screw and member and means for turning said member.

3. The combination with a casing, of a piston therein, a screw threaded in said piston, a member having operative connection with said screw and a passage to the interior of said casing through said member and a cap for operating said member.

In testimony whereof, I affix my signature.

JOHN W. DARLEY, JR.
