Specification of Letters Patent.

Pateiited July il, Trl-'M2- To all whom it may eonflein Be it known that I, JOSEPH lV. HAWKINS, a citizen of the United States, and a resident of Passaic, in the county of Passaie and State oi' New Jersey, have invented a new and Improved Tube, of which the tollowingis a full, clear, and exactdescription.

Tlie invention relates to dispensing cans, an d its object is to provide a new and inipr ved tube, commonly known as a paint tube, inade of tin foil Ior a similar niaterial,v 'toicontaining paint, tooth paste and other sernifluid substances, the tube being ar ranged to open by pressure :trom the outside with a View to govern the outflow of tli'e' tube contents onto a palette, tooth brush, spoon or a like article, and to close the tube by pressure of the contents from the inside on release of the outside pressure.

' For the purpose mentioned use made of a valve, controlling the outlet in the neel: of the tube, the valve `having.,i means exterior of the neck for pushing the plunger inward, and the valve having interior means subject to outward pressure by the contents o the tube.

practical embodiment ot the ii'ivention isf represented in the accompanying draw ings forming apart of this spet'itieation, in which similar Characters of reference indi'- eate corresponding parts in all the views.

Figure l is a side elevation ot the tube as applied; Fig. 2 is an enlarged sectional side elevation of the upper end of the tube dand showing the valve in a closed position; ',lig. 3 is a plan vieu' of the valve; Fig. it is a sectional side elevation of a modified form of the valve in open position; Fig. 5 is a similar View of another modified orin ot valve in closed position; and Fig. t; is a side elevation ot' the valve shown in Fig. 5.

The body A ot the tube terminates in a neck B, preferably made cylindrical, and having a peak-shaped top, one sido C ot' which is closed while the other side C' is open to form an outlet 'tor the t(contents ot. the tube A. In the neck lis mounted a valve for closing the neel: B and tor govern ing the outflow of the contents ot' the tube, the said valve beingT preferably in the i'orin ot' a sliding),` valve l) titled in the neelc B. The valve D is closed at its inner end so that the pref-sure of the contents ot the tube exerted against the said inner end of the valve 'forges the latter outward and holds the saine iiorinally in a closed position, as

indicated in Figi.

H Y lhe iali'e D is provided at one side with :i eliaiiiher ll, having' in its outer side an inlet opening ll'J tor the entrante olI the rontents ot' the tube, and

which contents are adapted tol pass through the eliaiiibei' D :it the time the also l) is 1n an open position :if: shown in lfigr. ll.A the 'toiiutents i'iassing through the open top l ot` the eliaiiiber ll. into the upper end ot tbe net-k Il and out through the outlet opening'. C inthe top ot' the neel: l.

As iiulirated in Figs. and l, ot the i-liaiiiber ll .is opposite the lost-d side C ot the pealt-.sliaped top oit the neck l` that when the .'alre l) is iii a olosed position the opening" D" is closed by the side (l. The 'valve l), adjatiiit the iliainboi' ll. is pimf'ided with an extension D* projomingg through the oliioniiitr C' ot the linie the i'ali'e lP is in :i eloseil position. as shown in Fig. 2, and the top of the extension l is preferably lit-.veled and liisli with the side G ot the neet: lli, as wili be readily under4 when the V toi' `the ft :i

stood by reference to Fig. i2. Non' tube A. used it is only nece operator topi-ess the projet-.tion lil' t fixed part, suoli as a. tooth brush or see Fil'. l), to 'toreo the i'alie A n'heroby'the Contents ot' the tubi: .li ea tliri'iiigli the inlet D2, the chamber the openings l, sind. C', onto the i and v bristles oty the tooth brush, the contents in tlowiiig,r

'over the inclined top ot' the g'u'ojeetion ll* being guided onto the bristles, as will be readily understood by referente to Fig. l.

ltis understood that. the 'aser exerts the usual pressure on the end of the bod).y of the tube so as to toreo the contents outward onto the tooth brush, palette or other artiele, and when a siillitieiit; quantity o't' paste 'has passed out of the tube and the user disengagfes the ,iroieeiioii D" from the artiele, then the valve U immediately closes by the pressure` of the contents of the tulle against iin the inner Closed end of the valve D. Thus y from the foregoing it. will be seen tliat'oii pushing the Valve l) .inward the neck l5 is opened to allow the outtlow'ot the Contents of the tube', and as soon :is the pressure on the project-ion D is released then the valve D is .forced outward into a olosed position by pressure of the Contents troni within the tube A. is shown in 'provided at the tern Et, with a spoonlilte er.

i, the if'iilvo it may lie nal ot thtA g'ii'oiw'tion tension lil, ',iei'eraliiy Itents of the tube passing onto the' said exf" tension E when using the tube as above described, and illustratedv in Fig. l, it being e understood that in this case the contents/of the tube instead of fioiving on, say,ra tooth brush, palette or the like, How onto the extension E. The inner end of the extension .E isprovided with a shoulder El yadapted to abutagainst the neck B so as to limit the inward or opening movementof the valve D.

Asf illustrated in Figs. 5 and 6, the valve F ismounted to slide in a neck'B, having an yinward extension B2 provided with -an outlet B3 normally closed by the valve F. The oute-rend of the valve F is provided with a recess F adapted to register with the outlet B8 at the time the valve F' is pushed inward into an open position, vso that the contents of the tube A can pass by wayfof the outlet B3 and the recess F into the outer end of the neck B through the outletB3 thereof, to a palette, tooth brush' or other article. The recess F of the valve F is opposite the closed portion B* of the peak-shapedtop of the neck B,;.while the hout1 et".opening Bs is on the other side yopposite the, inclined top F2 of the valve F, lso

that ivhen the latter is closed it closes the outlet pening B3. An arm G extends from thevalveF 'through an opening inthe por- `tion 13,l and lthe arm G terminates at its outer end in a foot-piece G extending paralle'l to the top portion B",

pressed against a tooth brush, palette or other'.l article, so as to' force the valve F inward into an open position for the contents of the tube A to pass out by Way of the, out- 'let B3. It will be noticed that by having the footG the inward sliding movement of the valve F is limited, and it is understood :that the outward movement of the valve F is contrpjlled by the pressure of the contents of the tu e.` y Having thus describedr my invention, I

claim as'new and desire to secure by Letters( p 1. A tube of the class described, provided with a neck having a peaked top, one side of which is open and the other closed, 'and a neck, said valve having a closed inner end,

a passage Vat one side and an inclined top portion on the side opposite the passage, the said inclined top portion of the valve and' adapted to a 4 tWo subscribing witnesses.V cylindrical valve mounted to slide in the having an inlet opening in its outer' side,

and With an inclined top portion on the side opposite the chamber, said inclined top portion being in alinement with the closed side of the neck when the valve is closed.

3. A tube of the class described', provided with a neck having a peaked top, one side of which is open and the other side closed, a cylindrical valve mounted to slide in the neck and having a closed inner end, said valve being provided at one side with a chamber having an inlet opening, and' with an 1nclinedtop portion on the side opposite the chamber, said inclined topportion being in alinement with the closed side ofithe neck when the valve is closed, and means on the 'valve and projecting beyond the neck of the tube for pressing the valve inward, said means also serving as a stop to limit the in Ward movement of the valve. p,

4. A Atube ofthe class described, provided with a neck having a peak-shaped top, one side of which is `open and the otherclosed,

and a cylindrical valve mounted `to slide in" the said neck and having a discharge compartment provided at the side with an inlet and at the top with an outlet opposite .the closed side of the top, the valvehavin a v beveled top of the neck of the tube 4portmn vprojecting through the open side of th top. 5. A tube of the class described provided with a neck having a .peak-shaped top, `.one side of which is open, and a `cylindrical val-ve mounted to slide in the neck ofthe tube and having a closed inner end and provided with a passage and an inclined top portion on the side opposite the passage, said .valve being provided with an extension for pressing it inward into the tube.
