' TUBULAR DISPENSER.

Application mea February as. 1924.` serial No. 695,856.`v

The principal objects of the invention are, toprovide a simple 'form of dispensing device for soap orother materials in paste form which maybe manipulated withease to dispense any desired quantityand which may be discarded without undue waste on the emptying of thecontainer.

- A further object isto Vdevise a container which will not leakaround the discharge end. I

The principal features o'f vthe invention consist in the novel- `construction and arrangement of parts,-where`by the spindle for operating the piston is held in operative Contact with the rotating meansby the resistance of the material being `,dispensed and by the friction of the piston and whereby the piston automatically disconnects from-the rotating means when the piston-reachesthe outward `limit of its movement. y

A 'further and importa-nt feature of the invention consists in the novel construction vof the dispensing closure with a flanged end, whereby the head of the container is sealed.

Figure 7 is a still further modification of the brush head connection.

Numerous forms of fountain shaving brushes have been devised butthe structures are complicated and diiicult to manipulate and are expensive to manufactureand costly and burdensome to maintain.

rlhe main idea in the present invention is `to provide a container which when Vemptied may be discarded: and replaced; by a new; one, and further to prevent the container from being refilled without a greatdeal of trouble. Y

.In the construction herein shown the containerr l is of vtubular for1n preferably of thin aluminumand in the forinillustrated in Figure l it is provided with a flange 2 double seamed thereto at the bottom end. .The upper end is formed with a taperingy shoulder 3 'terminating in athreadedY neck 4) the extremity of which is'turned inwardly inv a flange 5. Y l Y5 yA lisc is rotatablyarranged at the bottom end of the container resting against the fiangeQ and isl providedk with wingV projec-l tions 7 to enable it being turned with 'the thumb and forefinger. .i A slot 8 is -formed in the centre of the disc 7v and into this slot is fitted loosely a` flat -Vprojection 9` from the lower end of the threaded spindle l() which extends .longitudinally 'of' the container and is threaded witha vlett hand thread.`

The .piston 1l is formedfof cork or.- any other suitable material engaging the inner wall of the container and having a bottom plate 12 of thin sheet metal threaded on the stem and provided with lug projections V13' adaptedto extendk into and grip the piston. y

A vplatevlt ofthin sheet metal is secured to the top of the piston and is provided with one or more spring'tongue projections 15 stamped therefrom adapted to be engaged by a pin 1&6 secured transversely in the top end of the spindle 10 to lock the piston to the topv of the spindle when it has been 'moved out to the end and thereby prevent the refilling of the receptacle. f

It will beseen that by the rotation of the Vdisc 6 which engages the fiat end 9 kof .the 'spindle thespindleis rotated to cause the piston to travel toward the discharge end of Vthe container and when the piston reaches the limit of its outward movement and enspindle totravel through the piston, withgages kthe shoulder 3 of the containerpthe further. turning ofthe disc 6 causes the s 10G If the piston is pressed downwardly from the top end to cause the end 9 to again engage the disc and the disc is turned backwards the transverse pin 16 engages the tongues and simply turns the piston around, prevent-ing the piston from being drawn down toward the bottom of the container. p

The construction of the' bottom of the container may be altered in numerous ways, a modification being illustrated in Figure 6.

In the construction herein shown the con-` tainer is formed with an outwardly turned flange 17 .and a packing ring 18 surrounds the container above said flange.

The bottom `disc 19 is flanged to extend around the flange 17 and packing ring 18 ved on to the exterior of the cap and .is provided with an inwardly flanged end 2O engaging the top of the packing `ring and closely encircling the exterior 'of the container. 1

The head end of the container isas shown in Figure l provided with a threaded cap 21 which threads on to the neck t and is formed witli`an annular recess 22 and a central flanged opening 23. i

A dispensing tube 24 of rubber slotted at the top end is provided, with a circular base 25 iitting against the inner side of the cap and having an annular bead 26 to fit into the recess 22. This bead holds the flange from lateral displacement .when the cap `1s screwed down against the flange 5 of the threaded neck 4. A perfectly sealed joint s thus effected. vThe brush headV 27 is thread'- 21. j Several variations lin the form of the dispensing tube and brush head may be devised. In Figure 2 a threaded cap 28 is provided with an inturned return flange 29 holding a gasket 30 to engage the flange 5 of the neck. The dispensing tube is formedwith` a flatV flange 31 which engages the flange 29 and the brush head is provided with a flanged extension 32 which is secured to the cap 28 by means of any suitable form of slip fastener, such as a bayonet slot and pin 32. The flat section 33 of the brush head engages thelflange 31 and forms a tight joint therewit i.

In the form shown in Figure 3 the top end of the container is formed with an outwardly projecting rib 34k and the brush head is formed with spring lingers 35 adapted to spring over the head to hold the head tightly against the flat flange 31 of the dispenser tube. 1 i

In the form illustrated in Figure 6 the uppe-r end of the container is formed with an inwardly bevelled surface 36 above the j threaded portion to guide the brush head readily to the thread and above the bevelled portion the neck is flanged inwardly and formed with an outwardly flaring flange 37 forming an annular groove.

The resilient dispensing tube 38 which has a slit 38 in the outer end, is formed with a is removed. The brush head is threaded on p to the threaded neck of the container and is provided with a flat inner surface adapted to engage the outer side of the flanged portion 39 `of the tube to hold it from displacement.

The form shown in Figure 7 differs from that shown in Figuref, in that the threaded neck 4 is formed with an inwardly turned flange 41` which is' cupped on the outward side to receive a bead 42 formed on the flange of the rubber dispenser tube. The flange 4.1 holds the beaded portion ofthe tube flange tightly in contact with the brush head which is threaded on to the neck portion and reina-ins in the brush head when same isremoved from the container.

`Several variations in the detail construction of the joint connection between the brush head and container are herein shown but it will be understood that numerous other forms embodying the same principles may be adopted, so longasA the idea of providing a sealing flange on the base of the dispenser tube is adhered to.

A container such as described is extremely simple Jand inexpensive to manufacture and may therefore be `discarded when emptied.

What I claim `as my invention is 1. A dispensing container, comprising a tubular member, a rotatable member closing the bottom of said tubular `member and having a slot arranged centrally thereof, a spindle having a flat projection extending into said slot and withdrawable thereon through the rotation of said rotatable member, a piston threaded on said spindle, and resilient means for closing the outer end of' the container. Y

2. A dispensing container having an inturned annularllange at the bottom thereof, a rotatable disc engaging sadflange adjacent its outer periphery and retained therebyagainstjoutward pressure, a slot inthe centre of said rotatable disc, a threaded stem adapted to bear against saidv disc and having a flat projection extending loosely into said slot, a lpiston threaded on said stem and adapted to press the material from the dis-l charge end of the container, means for closing the discharge end ofthe container, and` Ward movement, a threaded spindle detachcontainer to eect a resistance to its outward ably and operatively connected With said movement whereby a rearward thrust is im'- bottom rotative member, and adaptedto bear parted Said spindle to maintain the same in 10 directly against said rotative member, and operative engagement with said rotatable a piston sealing said Container and threaded member.

on said spindle and having` its periphery frictonally engaging the inner Wall of said 'FRANK MCLAUGHLIN.
