Renewed April 10, 1935 i privation February 14, 1934, serial N0.v11 ,23ol i sfclaims. l (cl. zel-soi This invention'relates to certain new and us j `ful improvements*finodispensing tubes. i In dispensing" tubes; such Jas, those containing f tooth paste, shaving cream and other lotions, `itV `is customary to close the outer end'of the tube nozzle inwardly` of theclosurecapwith a calk disk, and infsome instances, a soft metal plate ordisk thatmay `bereadilyjrenioved from the dispensing-nozzlefbut in dispensing" tubes comprising` a valved discharge nozzle or` arrangevide a proper seal Vfor the tube. Itis therefore o theprimary object` of this invention vtoy provide a.` valved nozzle for-a dispensing tube wherein `the inner end of the nozzle is `normally closedby the bottom wall of thefnozzle and which bottom wall isadapted, toibe cut away, similar tothe ordinary Vopening of a tin can closureby a' knife attachment carried lby the inner end-of a valve element movable within thedischarge nozzle." f Itiis a further object of the invention to provide an interlocking connectionbetweenlthe discharge nozzle and valvedclosure therefor to prevent disengagement of,` the valved closure from closure..1` n "i i `With the above and 'other objects in view that o will become" apparent as the nature of the inventionis `better understood, the same consistsin lthe novel form, combination andarrangemcnt 'o'f parts hereinafter more fully described, shown iny the accompanying drawing and claimed. n

Figure 1 is a fragmentary longitudinal sec`- tional view of the dispensing tube constructed in accordance with the present invention, showing` the valved closureat its' limit of outward movement and the cutting blade at the inner endl4 thereof spaced from the closedbottomwallof `the dispensing nozzle; 1w e i ff-` 1 Figure 2 is a fragmentary sectional view, similar to Figure 1, showing the valvedclosure at 4its? limit of inward movement withinthe discharge nozzlewith `the knifecutting andopening inthe Abottom wall of the discharge-nozzle; l t `Figure 3,is` a side elevational viewof the valved closure removed from the dischargeor dispensing `Figurefiis a cross-sectional view taken on line 4-4 of Figure 1, showing the closedbottom wall of the dispensing nozzle; vand 1 i Figure 5iis a horizontal sectional view, simi-.

Referring morein detail to the accompanying drawing, the reference numeral I designates a dispensing tube of the type usually employed for containing shaving cream, tooth paste or lotions i of any character,- the collapsible tube I0 having a 60` `semi-rigid"outerend wall `II that` supports a the dispensing. nozzle and 'consequent loss "of the l o original position of the outer end of the tubular nozzlefl! being indicated at I4 by-dotted lines in Figure 1. As shown in Figures 1 and 2, the discharge nozzle I2 is internally threaded as at" I5, the 'threads `extending inwardly from the outer end of the nozzle and terminating in spaced relalo tion to the bottom wall I3, these threads taking avalved closuredevice forthe dischargenozzle.

The valved closuredevice a`s"illus`trated in de- `tail iii-Figure 3 is `cylindrical in cross-section, be-

ing designated in generaliby `the reference character I6 and incldsan intermediate threaded portion; IIhaving a terminal Unthreaded tapered `inner end I8 with a`cutting fngeror blade I9 depending'from' the tapered end I8. The outer portion ofthe valved closure I6 is of reduced di- 2o ameter asat 20, providingan intermediate abutment shoulder 2I. A disk operating head 22 `is carried by the terminalouter end of the valved closure IBand the underside of the disk `head 22 has a curved surface`23 shownin Figures 1 `and2 25 of increased depth adjacent the reduced portion l A longitudinally-extending:bore 124 is formed in the valved closure'that `opens at the inner end thereof andthe outer end ofthe bore `21Iis di- K rected at right angleslas at 25 to provide a` dis- 30 charge opening in vthe-reduced portion 2li of the valved closure.' i A In assemblingthe valved closure I6 with'the discharge" nozzle I2, the outer end I4 of the dis# charge nozzle is in the position illustrated by l dotted lines in Figure l and upon threading the valved closureinwardly "of` the discharge nozzle, Y the `outer end` `I 4 ofthe nozzle is spun inwardly i by contacting the curved surface 23 on the under sideof `the `disk head 22 to assuxnethe position 40A shown in Figure 1. `Thevalved closure is threaded into the nozzle a surlcientdistance to `cause the` nozzle I2at its outer end to provide a closure .foro

thedischargeopening 25, but insuiiicientto cause" the cuttingilngerory blade I9 `to `sever the bot- 45 tom wall I3 of'thejnozzle. Upon complete inward `mate contact between thevalved closure andinozzle. `Thls complete inward movement of the valved closure also causes further inward spin` 55A ning movement `of the outer end I4 of the discharge nozzle to'c'ause the same to be moved into wiping engagement lwith the reduced portion 20 of the valved closure. This inwardly spun flange I4a"` is intended for abutting engagement with the 60 shoulder 2| on the valved closure to prevent accidental displacement of the valved closure from the discharge nozzle. In the use of the tube, the valved closure is moved outwardly of the discharge nozzle to the position shown in Figure 1 and with'the disk portion I3a out out of the bottom wall I3 of the nozzle, pressure on the tube i I forces the contents thereof through the longitudinal bore 24 and lateral discharge opening 25 in the valved closure for the dispensing operation. As shown in Figure 2, the disk I3a out from the bottom wall I3 of the nozzle is disposed laterally of the opening in the bottom wall so that the contents of the tube may be dispensed with liability of the disk closing the opening eliminated. The cutting blade I9 extends substantially in the plane of the bevelled end I8 of the valved closure as shown in Fig. 1, so that during threading movement of the valved closure toward the position shown in Fig. 2, the disk I3 a is cut from the bottom wall I 3 of the nozzle, and with the arrangement of the bevelled end IBand cutting blade I9, the cut disk I3a is moved to a position laterally of the opening. With the valved closure completely moved home as shown in Fig. 2, the

y disk I3a remains attached to the bottom wall of the nozzle by a narrow finger portion of the material that forms a hinge connection between the disk and nozzle so that the disk will always remain laterally of the bottom wall opening in the nozzle and will not interfere with the dispensing of the-contents of the tube. To close the tube, it is only necessary to thread the valved closure completely inwardly of the discharge nozzle whereupon the flange Ida moves into the pocket provided by the curved bottom surface `23 upon the disk head 22 and the lower tapered end I8 wiping over the lower unthreaded portion of the discharge nozzle, the tube contents, or a porY tion thereof within the valved closure are returned to the tube Il).

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 to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
