LOUIS FISENNJE. OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO CHARLES GOLDIVIAN,

or NEW YORK, N. Y.

DISPENSING DEVICE.

Specification of Letters 'I'atent.

Patented May 18, 1915.

To all whom it may concern:

Be, it known that 1, Louis Frsnnnn, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Dispensing Devices; and 'Ido declare the followmg to be a full, clear, and exact description of the invention, .such as will enable others skilled .in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to dispensing tubes 'or receptacles particularly adapted for dispensing dental or toilet paste or cream in ribbon-form although not restricted to that use. i

It has for its object to provide improved features of construction and arrangement of parts whereby there is combined with the ejection-plunger a closure-cap having a centrally disposed nipple in alinement with the discharge nozzle so that as the plunger is moved toward the discharge end of the tube or receptacle the plastic substance will be forced through the'centrally disposed nipple into the discharge nozzle, and the compression of the plastic or paste between the faces of the plunger and closure-cap will cause the plastic to follow the plane of said faces and find its exit into the centrally disposed nipple and thus practically the entire contents of the tube or receptacle are ejected instead of finding lodgment between the closure-cap and plunger.

It also has for its object to combine with the plunger which moves the body of the plastic toward the discharge end of the tube, a winged propeller disposed in the discharge nozzle and connected thereto and to the lunger reed screw so that as the plunger orces the paste or plastic into the nozzle the winged propeller divides the paste or plastic and propels 'it forward to the elongated discharge orifice in the end of the nozzle so that it is ejected in a tape or ribbonform. The propeller serves to control the volume ,of the plastic passing through the nozzle and gives momentum to the portion acted on by the propeller so that it is ejected at such speed as will project it in a relatively compact ribbon and thus prevent it from folding over the mouth of the nozzle as it otherwise would do.

It has further for its object to facilitate the easy assembling of the cooperative parts and their attachment to the tube or receptacle as well as detachment when necessary and also to provide for their easy operation.

To the accomplishment .of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter described and then sou ht to be clearly defined by the claims, re erence being had to the accompanying drawing forming a part hereof, and in which Figure 1 is a side elevation'of a receptacle having the invention applied thereto; Fig. 2 1s a longitudinal section through the same;

Fig. 3 is an end View looking at the discharge end with the nozzle-cap removed; Fig. 4 is a sectional view on the line 4-4: of Fig. 2, looking in the direction of the arrow; and F ig. 5 is a perspective of the.

propeller.

In the drawing the'numeral 1 designates a tube or receptacle made of any suitable material and of any approved polygonal shape in cross-section although the form selected for illustration is shown as hexagonal and having at one end external threads 2" and internal threads 3." lVithin one end of the receptacle there is fitted a closure-cap 4 the rim of which is threaded or formed with spiral grooves 5 so that the cap may be screwed into the receptacle in engagement with the screw 3. ,The closure-cap is formed centrally with a ni pie 6 through which passes a screw rod 7 which at lts lower end may be stepped in a suitable seat 8 formed in the end of the receptacle. The screw-rod carries a plunger 9 which is of suitable polygonal shape in outline corresponding to the polygonal shape of the receptacle so as to have non-rotatable 'but ,slidable contact or engagement with the connected thereto.

6, in the manner of a sleeve, and the nozzle is provided externally with a disk 14 the periphery of whichmay .be milled for ease in turning the disk and nozzle. The disk is carried by a cap 15 the rimof which is formed with spiral grooves or threads 16 for threaded engagement with the external threads'2 of the receptacle by which means the nozzle and disk are rotatably attached described,'and assuming that the receptacle or container between'the plunger and the closure-cap contains a pasty or plastic substance, such as dental paste, now if the disk 14 is rotated, the nozzle 12, propeller 10 and screw-rod 7- will be rotated so that the plunger 9 will be moved toward the discharge end of the receptacle thereby forcing the plastic into and through the nipple 6 .into

. range of the propeller 10 which will engage the plastic and carry it to the front and propel it forward to the discharge orifice of the, nozzle through which it will be projected in a compact tape or ribbon.- The propeller will give density or compactness to the paste or plastic as well as regulate its volume passing beyond the propeller and at the-same time feed it as specified-through the nozzle; and the wings to the propeller will hug to the walls of the nozzle and keep the plastic from adhering or caking next to the walls.

- I have illustrated and described with particularity the preferred details of construction but they can be varied without departing from the essentials of the invention.

Having described my invention and set forth'its merits, what I claim is 1. A dispensing device comprising a container, a screw-rod carrying a plunger and having at its outer end a propeller and a rotatable nozzle to which the propeller is attached to rotate therewith, substantially as described.

2. A dispensing device comprising a containei', a plunger within the said container, a screw-rod for moving the plunger, a nozzle attached to the screw-rod, a propeller within and rotatable with the nozzle, and a disk connected with the nozzle to rotate the lat- -ter, substantially as described.

3. A dispensing device comprising a container, a closure-cap fitting within one end of the container and having a centrally disposed nipple, a discharge nozzle sleeved to the nipple of the closure-cap, a plunger within the container, a screw-rod for moving the plunger and fitting within the nipple and nozzle, and a propeller in the nozzle and connected with it and the screw-rod, substantially as described.

f1. A dispensing device comprising a contamer, a plunger, a screw-rod for moving the plunger, an internal closure-cap fitting within one end of the container and having a centrally disposed nipple, an external cap secured to the end of the container, a rotatable discharge nozzle provided with an 0perating disk and having a swiveled connection with'said cap, said screw-rod and rotatable nozzle being operatively connected with each other, substantially as described.

, In testimony whereof I affix my signature in presence of two witnesses.
