WITNESSES l ENVENTOR d/ Q@ n v @Y WWW ATTOR NEY Patented `lune 17, 193?1 CLAUDE A. CON'OVER, OF NEWBURGH, NEW YORK CLOSURE FOR TOOTHPASTE TUBES Application led June t', 1929. Serial No. 369,148.

This invention relates to closures for toothpaste tubes, and has for an object to provide an improved construction wherein means are presented for normally keeping the tubes sealed, but which may be readily operated by the thumb of one hand.v

Another Objectis to provide a toothpaste tube closure formed with means capable of being moved to an open position by the thumb and also formed with means for returning the parts to a closed position after lthumb has released the closure.

A further object, more speciically, is to provide a closure formed with a rotating closure plate having a discharge opening therein capable of being brought into registry with a guiding tube when moved to one position and capable of being moved to a closed posiytion by a spring, the structure coacting with a resilient lock for holding the plate in an open position.

In the accompanying drawings,-

Figure l is a perspective view of the upper part of a toothpaste tube with Ia closure disclosing an embodiment of the invention applied thereto;

Figure 2 is a top plan view on an enlarged scale of the structure shown in Fig. 1;

Figure 3 is a sectional view through Figure 2 approximately on the line 3 3, the same being on a reduced scale;

Figure 4 is a view similar to the upper part of Figure 3 but illustrating the parts in an open position.

Referring to the accompanying drawings by numerals, 1 indicates an ordinary, collapsble tube for toothpaste, said tube merging into a neck 3 provided with a division plate 4. This division plate may be made separately and soldered or otherwise fastened in place, but for the purpose ofillustration it has been shown as bent over at point 5, so that it is integral withneck 3.

The essential features are the provision of the plate 4 with a chamber 6. ln toothpaste tubes various closures have been provided for maintaining a proper closure when 'the tube is not in use, while permitting ready withdrawal or ejection of the toothpaste whenever needed.

In the present invention an improved structure is provided which permits a ready withdrawal at any time and which provides a proper closure or seal, whereby the remaining toothpaste is maintained in its proper condition. Many toothpaste tubes in use today merely have a threaded neck with a screw cap, and this requires the use of both hands to properly manipulate so that toothpaste may be removed. 1n the present instance it is designed to present a structure which may be manipulated by one hand, and after manipulation the same hand may be used to squeeze the tube to produce the desired dscharge of toothpaste. 1n carrying out this idea a closure disk 7 is provided which is preferably comparatively thick, though this is not essential. The periphery of this disk is preferably knurled, so that when grasping the tube 1 the thumb of the hand may readily rotate the disk. As shown particularly in Fig. 3, the pin or rivet 8 extends through the center disk 7 through a spacing sleeve 9 and through plate 4. This holds the disk 7 in sliding contact with the upper edge of the neck and also in sliding contact with the paste discharge pipe 10, which pipe is soldered or otherwise secured rigidly tothe plate 4. A pin 11 is rigidly secured by solder or otherwise to the plate 4 and/ extends through the arc-shaped slot 12, but loosely lits therein so that it will act as an abutment `or stop for limiting the rotary movement of the plate 7, whereby the discharge aperture 13 may be brought into exact registry with the pipe 10 and may be moved out of registry therefrom. In moving the aperture 13 into registry with the pipe 1'() the disk or plate 7 is operated by the thumb,

but when it is desired to move the disk or plate in the opposite direction the same is actuated by the spring 14. This spring at one end is rigidly secured to the enlargement or fastening means 15 and at the opposite end is loosely-fitted into theaperture 16. Member l5 ma)v be an integral part of the neck 3 ormay be a separate member soldered fast thereto. Spring 14 continually tends to move the parts to the position shown inFigs. 2 and 3. "hen the plate 7 has been moved by the thumb to .the position shown in Fig. 4 it may be locked in this position by the spring 17, which sprin extends continually into the slot 18. When t e parts are moved to the position shown in Fi -4, the end of spring 17 snaps' into the notc 19, and consequently, holds the plate 7 a ainst return movement, spring 17 being sti er and stronger than spring 14. When it is desired to permit late 7 to return to a closed position the thum passes against the end of spring 17 until the sprin is disengaged by the notch 19, whereupon t e spring 14 will immediately function to move the disk to a closed position. It will be noted that the actuation of the disk in one direction is by the thumb of a halid and the release of the spring 17 is completed by the same thumb, so that only one hand is needed for actuating the closure, and the same hand may be used for squeezing the tube l'to produce a desired discharge of toothpaste.` In order to lubricate the various parts and prevent the toothpaste from hardening at the juncture between pipe 10 and aperture 13, a filling 20 of cotton or other fibrous material is provided in chamber 6, and this cotton or other fibrous material is saturated with castile soap or some other desired grade of soap iavored with the same flavor as the toothpaste' As the partsmove the resiliency of the fibrous filling 20 will cause the under surface of the plate 7 to be lubricated, and consequently, permit a ready movement thereof, as heretofore set forth.'

2. A closure for toothpaste tubes, including means forming a chamber at the upper end of the neck of the toothpaste tubes, a filling in said chamber consisting. of fibrous material saturated with. a flavored soa which acts as a lubricant, a dischar tu extending through said chamber, an a utment extending through said chamber, a pivotal pin extendlng through said chamber, a closure disk rotatably mounted on said pivotal pin, said disk having an arc-sha ed slot for accommodatmg part of said a utment pin, whereby the abutment pin limits the back and forth movement of the disk, said disk having a discharge slot adapted to be brought into registry with said discharge tube, said disk hav- -ing an arc-shaped slot formed with a notch .near one end, ak locking spring extending into said, Vslot and positioned to snap into said notch'when the disk is moved to an open po- Sitten.,-
