BASTE-TUBE CAP.

application mea umh 4, 1922. serial No. 541,100.v

To ZZ whom it may concern Be it known that '1, WALTER W. CARPEN- Tan, a citizen of the United States, residing at lCharleston,` in the county vof Charleston and State of South Carolina, have invented certain new and useful Improvements in Paste-Tube Gaps, of which the following is a specification, reference being had to the accompanying drawings.

It is the purpose of the present invention to provide a cap for variousY paste tubes, suc as used for containing tooth paste, cold cream, paints and the like, to permit access to such contents easily and qulckly.-

Heretofore, it is well known that the ordi-A nary caps become larlythe threaded neck of the tube, due to the constant removing and reattaching the cap, taking up considerable time, which is very annoying in every respect. Furthermore many users of paste which is contained in tubes remove the caps and place them on a shelf, very often forgetting to replace them on the tubes. Very often the old caps drop into the sink, etc. and also become lost and in this way the paste oozes from the tube and also vliardens in the mouth of the tube and therefore creates waste and inconveniences.

llt is, therefore, another purpose to provide a cap, as an article of manufacture, entirely independent of the tube and capable of being applied to all makes of tubes, generally a threaded neck is used. In' other words when opening a tube of tooth paste the cap may be removed and discarded, and the present form of cap screwed to the neck, and in this case, when the occasion requires, the cap proper may be tilted to an open position, by pressing upwardly on the flange 11, thereby permitting the paste to be discharged by depressing the sides of the tube. After the necessary quantity of paste has been taken, the cap proper may be easily closed by pressing the forefnger thereon. After the tube is emptied, the cap may be detached and then ap lied to a new tube of paste, regardless of t e character of paste.

While the design and construction at present illustrated and set forth `are deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes,.the invention may be susceptible of changes, and. the right to these changes is claimed, prodistorted, and particuor the like. I threaded neck 2, which is ordinarily ro- 75' vided they are comprehended within the sco of whati claim d.- ,if S e.

e invention comprises further features and combmatlon of parts, as will be here-v inafter set forth, shown in the drawings and 00 in the improved cap a plied;

igure 2 is asectiona view on line 2 2 of Figure 1, showing the structure of the ca on an. enlargedV scale; and

igure 3 is an enlarged detail perspective view of the cap detached from the tube.

Referring to the drawings, 1 designates a tube, which maycontain paste, of any character, such as tooth paste, cold cream, paint The `tube is provided with a vided with the usual threaded cap, w ich comes with the tube. Threaded tothe neck 2 is aband 3, which has a lateral arm 4, the end of which is bifurcated at 5. Formed integral with the arm 4 as at 6 is a extension 7, which is located below the arm 4, and'extends vin the same general plane with the arm. When the spring extension is not under tension, it assumes anormal parallel position with relation to the arm 4. 85

Pivoted on a pin 8 and arranged in the bifurcation is an arm 9 carrying a cap or lcover 10, constructed integrally therewith.

rlhe cap 10 is provided with an annular ange 11, which tits down over the band 3, 90"

there being a soft 'bre washer or :filler or gasket 12 fitted within the cap 10, and adapt'- "edto engage theedge of the band 3, to 1nsure a tight twith the band, so as to prevent any leakage of the paste. The hinged- 96 end of the arm, which carries the cap, is provided with a cam which rides upon the spring extension 7. The cam 13 lis so disposed relatively to the pivot of the arm.

ycarrying* the cap, as to vhold the cap either 106 closed or open. `In fact when the cap is entirely open, the larger portion of the cam is `positioned at a point toward the band, in fact-between thefpivotof the arm and the,

band, and a flatportion 14 of the pivoted 105 end of the arm 1s in engagement withthe spring extension 7, the

open.

It is obvious that by elil-ninating the threaded connections between the band 3 and l Y spring y holding the cap i the' neck 2 of the tube, and constructing the band integralwith the neck, or to construct the lateral arm 4 integral with the neck, it is possible to manufacture the cap as apart of the! tube, instead of threading the band- 3 on the neck of the ordinary tube.

Thek invention having been set forth, what is claimed is 1. A closure member for receptacles embodyin a receptacle having a neck, a collar engage with said neck, said collar having an extension, a cap adapted to engage vone vedge of the collar, said cap having an extension adapted to b'e pivotally connected to the extension of the collar, said vextension including means for engagementwith the end of the extension of the cap for holding said cap in its raised position. a

2. A closure member for receptacles embodying a rece tacle having a threaded neck, 20

an internally t readed collar detachably engaged with theneck and projecting. above the neck, said collar having an extension, said extension including parallel arms, the lower arm serving as a spring, the upper arm having its end portion biurcated and provided with a pair of spaced ears, a cap adapted toengage the collar, said cap havin an extension, one end of said extension being pivoted betweenthe ears of the upper arm,.said pivoted end havingl an enlargement adapted to be engaged by the-,spring arm for holding the cap in its raised or lowered position.

In testimony whereof I hereunto ailix my $6 signature.
