Application my z, 1932, sei-iai No. 608,111 Renewed August 28, 1933 21 claims. Een, azi-so) This invention relates to certain new and useful improvements in paste tube cap.

The primary object of the invention is to provide a paste tube for containing and dispensing cream, paste, liquids or other viscimsY substances provided with a closure cap permanently carried by the dispensing end oi the tube I and operable by a cam movement for opening and closing the passage through the discharge w V:nozzle of the paste or dispensing tube.

.A further object of the invention is to provide o paste tube cap of the foregoing character in which the cap hasan opening therein normally closed by a spring supported valve which is shifted to an inoperative position by a cam connection vbetween the cap and neck of the paste tube with the discharge nozzle of the tube projected through Y the cap opening.

With the above and other objects in view that g@ will become apparent as the nature or theinvention is better understood, the same consists inthe novel form, combination and arrangement ofI parts hereinafter more fully described, shown in the accompanying drawing'and claimed.

more in detail to the accompanying drawing, the reference character 15 designates 65 a collapsible tube of the character usually emplayed in containing -and dispensing tooth paste, shaving cream, ointments, or other viscous substances, the discharge end of the tube having A a relativelyr large neck 16 carrying a centrally 70 disposed discharge nozzle 17/of lesser diameter than the neck 16. The neck 16 is provided with an externalrthread or cam groove 18 merging at opposite ends into upper and lower annular grooves 19 and 20 respectively with which the 75 cap 21 is associated. A s shown in Figures 11 and 1.2 the lower annular groove 20 terminates at 21a 'in spaced relation to the cam groove 18 while the upper annular groove 19 in spaced relation to the entrance end of the cam groove 18 has a down- 80 ward inclination 19a for purposes presently .to

appear. As shown more clearly in Figures' 9 to ll., a cam lug 22 is superposed on the upper face of the tube neck 16 and. extends radially of the nozzle 17, being spaced below the upper 35 end of the nozzle. The closure cap 21 carries an annular skirt or side flange 23 carrying at its free edge, diametrically opposite inwardly directed lugs 24 working in the cam groove 18 and annular grooves 19 and 90 20. The top wall of the closure cap 21 is provided with a central opening 25 of a diameter to permit the passage of the discharge nozzle 17 therethrough in a manner to be presently described and said opening 25 is normally closed by a valve 95 device'26 having upper and lower bulbous portions 27 and 28 respectively for engagement with the walls surrounding the opening 25 in the cap and the opening in the discharge nozzle 17 as shown in Figure 1. The valve device 26 is 10g carried hy'a spring arm 29 that is anchored at one end as at 36 to the inner face of the annular ange 23, the normal position of the spring arm 2Q positioning the valve device 26 so that the upper bulbous portion 27 thereof is received in 105 the opening 25 in the/top wall of the closure cap 2l..

when the cap 21 is in its closed position with respect to the discharge nozzle 17 -of the pastetuhe 15, the lugs 24 carried by the cap. are dis' un ,g acreage posed in the upper annular groove 19 in the neck 16 of the tube with one of the lugs engaged with the inclined portion 19a of the upper ang nular groove 19 for causing the cap to move in a downward direction to bind the valveY device 26 in closed position with the bulbous portion 27 extending into the cap opening 25 and the bulbous portion 28 closing the opening in the discharge nozzle-17 so that the Vpaste tube is securely closedand the contents thereof maintained in a `clean and sanitary condition. When it is desired to dispense material from the tube 15, the closure cap 21 is rotated in a counterclockwise direction, the lugs-24 rapidly moving through the cam groove 18 to lower the cap on the neck 16 and to align the cam lug 22 with the spring arm 29. Continued rotation of the cl-osure cap causes the cam lug 22 to move the spring arm Y2,9 against the tension thereof :and to laterallydisplace the valve device 26 to the positions shown in Figures 71; 8 and 12 so that continued movement of the cap will cause the discharge nozzle 17 to be projected through the cap opening 25 into the position shown'in Figure l2,

whereupon the contents of the tube may be readily dispensed therefrom. YThe cap is moved to a closed position Yrelative Yto the tube and discharge nozzle 17 by a reverse or clockwise rotation of the same to assume the closed position illustrated in Figure 7. It will be observed that the upper annular groove in the neck i6 of the tube is of a construction to prevent complete removal of the capY 21 from the tube neck so that the cap is permanently carrie-d by the tube but movable over the neck portion thereof for opening and closing the discharge nozzle and limited in such movements to prevent loss of the cap.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent and while there is herein shown and described the preferred embodiment of 'the invention, it is nevertheless tobe understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
