H. s.l s'rour DISPENSING CONTAINER .Filed DSG. 21, 1927 ATTORNEY Patented Nov.- 1'3, .1928.

UNITED 'STATES HARRY `S. STOUT, OF HUNTINGTON, WEST VIRGINIA.

DISPENSIN G CONTAINEM.

y Application led December 21, 192.7. Serial No. 241,739.

An obj ect of the invention is the provision of a container for readily -dispensing semi- -luids and in which a combined lever and cap is employed for revolving a high pitched screw whereby a slight turn of the lever will cause a rap-id advance of the plunger within the container for forcing i'luids'from the container.' A

A further object of the invention is the provision of a dispensing container in which a plunger is employed' for forcing a semi-fluid from a restricted opening by means of a high pitched screw, 'the same being in 'turn operated by a combined cap and lever connected with a rotatable cover, the lever establishing a greater leverage so that screws of higher pitch may be employed for the purpose.

This invention will be best understood from a consideration of the following detailed description in connectionwith the accompanying drawings; nevertheless, it is to be understood that this invention is not conned to the disclosure lbeing susceptible of such changes and modifications as shall define no material departure from-the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a view in perspective of a dispensingv container constructed according to the principles of my invention, p

Figure 2 is a vertical section of the same,

Figure 3 is a fragmentary vertical section through part of the operating mechanism of the dispensing apparatus,

Figure 4 is a view in perspective of the rotatable closure for the container,

Figure 5 is a horizontal section taken along the line 5-5 of Fig. 2.

Referring more particularly to the drawings designates a container or cylinder havin the lower end open which is adapted to be c osed by a flange cap 11 having an annular flange 12 embracing the -lower lend of the container and abutting a shoulder 13. The outer surface of the container is ribbed, as shown at 14, whereby' the container may be readily held in the hand for a purpose which will be presently explained. The upper end of the container is c osed, as shown at 15 and 4is provided with a central passage 16. The

top 15 is extended, as shown at 17.

A screw 18, having high pitched threads is mountedaxially of the container and receives 4the internal threads on a centrally disposed passage 19 of'a piston 20. This piston hasa packing 21 and an annular groove in the perlphery which engages the inner wall of the container 10.

The upper end of the screw is formed into ahead 22 having a central passage 23 which opens into a radially disposed passage 24. The head is provided with an annular flange 25 which has a down turned knurled portion 26 from which extends laterally disposed lugs 27 adapted to engage beneath the under face of the flange or extension 17. The top 15 of the container adjacent the central passage 16 is provided with an inclined seat 28 adapted to receive a similarly formed portion on the 4head 22 in order toprovide a tightiitbetween the top 15, the head 22 and the upper portion 29 of the screw 18.

An arcuately shaped lever 30 is pivoted on a pin 31supported by the annular flange 25 and a coil spring 32 is located between the lever 30 and a head 33 of the p-in 31. This lever is provided with a nger piece 34 for operating said lever and for rotating the flange 25. v

A cap or closure is adapted to be seated upon the upper reduced end of the head 22 for closing the outer end of the passage 23 and maintained in place by an arm 41 secured to the lever 30. The inner end of the lever,

as shown in dotted lines at 42 in Fig. 4 is adapted to abut a shoulder 43 on the head 22 and maintain said lever in the position shown in said figure when the member 25 is revolved.

The outer` ribbed surface 1'4 of the container may be provided with a section for the application ofthe name of the ingredients contained therein. Another section may be provided, as shown at 51, having an arrow 52 to indicate the direction the lever and likewise the cap 25 may be rotated.

` The operation of my device is as follows:

Pressure is applied to the finger piece 34 by means of the thumb while grasping the ribbed surface of the container in the hand, whence the lever 3Q will be moved to the position shown in Fig. 4, thereby releasing the cap 40 from the passage 23 while at the same time causing rotation of the head 22 and likewise the flange or cap 25. Rotation of the head causes rotation of the screw 18 whereby the plunger 20 will be moved towards the upper end of the container and force semi-fluids lcontained therein through the passage 23.

A reverse rotation as lndicated by the arrow in Fig. l will cause the plunger to be moved towards the opposite or bottom of the container and the cap l1 may be removed and likewise the plunger. The materials are then lled into the container with the cap 40 in position closing the passage 23 after which the plunger is then applied to the threads of the screw 18 and moved inwardly of the extreme lower end of the container. The cap then is applied and the lever may be moved to an operative position for rotating the head 22 and likewise .the screw 18, so that the plunger 20 may be moved as desired for forclng portions of the semi-fluid from the container.

It willbe noted that the coil spring 32 has vone end, as shown at 50, secured to the head 33 of the pin 31, while the other end of the lspring is secured at51 to the lever 30, so that when the lever is moved to the position shown in Fig. 4 and released, the spring will return said lever to its normal position whereby the cap 40 will close the opening 23.

1. A dispensing container comprising a barrel, a screw within the barrel, a piston havin means engaging threads of the screw where y rotation of the screw will cause movement of the piston longitudinally of the barrel, a dispensing head mounted for rotation on one end of the barrel and rigid with the screw, said head having a discharge passage for liquids, a closure for said passage, a lever` pivotally connected with the head for moving the closure to an inoperative position, while providing means for manually rotating the head and likewise the screw.

2.- A dispensing container comprising a barrel, a screw within the barrel, a piston havin means engaging threads of the screw where y rotation of the screw will cause movement of the piston longitudinallyl of the barrel, a dispensing head mounted for rotation on one end of the barrel and rigid with the screw, said head having a discharge passage for liquids, a closure for said passage, an arcuately shaped lever p-ivotally mounted on the head, said closure being rigidly connected with the lever, said head being provided with an abutment, the lever having one end adapted to engage the abutment for restricting pivotal movement of said lever so that when the lever is moved to a predetermined position the head may be revolved.
