PASTE DISPENSING DEVICE Filed Jan. 27. 1939 f Fig. I.

In ventor fa/2J Prifysaxf Attorney Patented Jan. 23, 1940 UN1TED-STATE y PASTE DrsPENsrivG DEVICE Karl Pringsauf, Heidelberg,V Germany, assigner to Willy Mansbach, London, 'England Application January 27,' 1939,`seria1 JN0. 253,194 In Germany February 12; 1938 6 claims." l(011." 22114-73)A This invention relates tocontainers for substances of pasty consistency (hereinafter referred to as paste) having means for dispensing y( the contents invariable portions as and when required, without the necessity for removing the container lid or closure.'

Objects `of the invention are firstly to provide' a simple, handyV and effective paste dispensing n device of this? character capable of being manu- To factured easily `and cheaply, and secondly, to

ensure at all times a hygenic discharge or extrusion of thecontents of the device. e

A' paste dispensing device in accordance with the invention comprises an internally round,

I5 closed container having a paste discharge opening in one of its walls, a post iixed centrally in the container, two radial varies-extending one rotatably and the other non-rotatably from the post to the inner peripheral wall of the container and means for rotating the rotatable vane from the exterior of the container. The `device mai7 also include means for automatically sealing and unsealing the discharger opening on opposite directional movements of the rotatable vane.

Preferably one end Wall of the container is constituted by a rotatable lid having. the paste discharge opening therein and also having, near said discharge opening, an inwardly projecting pin or equivalent to'engage and rotate the rotatable vane.

The rotatable vane has or may have a bent- 40 able, for example, for containing face cream or toilet cream, and to be carried ina ladys handbag, is illustrated on the accompanying drawing l to which reference will now be made.

Fig. 1 is an exploded perspective view of th complete device.

Fig. 2 is an inverted plan view partly with the base broken away.

On the drawing I denotes the body of the box or container, and 'I the lid or closure. Internally, the depending flange of the box lid 'l has spaced circumferential grooves I 0 to interlock e with spaced external projections 9 on the reduced neck of the box body I. Thereby the lid can be `fitted to the box` body in one position but is retained against removal during its sub- `and Ila/of two- 'radial vanes 3f and 4 respectively.

sequent rotation for the purpose hereinafter explained; i i i A Inside the boxbody I 'isxed as by soldering aV central post 2 adapted to receive the bosses 3a This post 2 has a key-wayiZa extending for a i part of its length and adaptedto. receive a key or'fefather-fixed in the boss a of the vane 5,

whereby this'vane is held immovable. The other vane 3 isl free to rotate about the axis of the post. 10

The box lid 'I has a paste discharge opening "8, andit also has an inwardly projecting `pint which is 'adapted to engage a' 'slot 3c'in the bentover portion 3by of the vane 3. The pin 6 may be soldered in position on the lid. 15

With this construction only the parts 2 and 6 have to be integral with the box body I and lid 'I respectively, the vanes 3 and 4 being separately removable. This facilitates and also cheapens the cost` of manufacture of the deviceas a whole.` 20 I It J will be readily understood that after the vanes Band 4 have been mounted on the post 2 and?v after the vane 3 has been turned back to abut the vane 4, the box I may be charged with paste whereupon the lid 'I can be applied so that 25 the pin 6 engages the slot 3c. Under these conditions the relative positions of the parts will be as shown in the inverted plan View, Fig. 2. If now the lid 'I is turned in the direction of the arrow in Fig. 2, it will rst of all be displaced 30 relative to the movable vane 3 to the extent permitted` by thefslot 3c. During this initial movement, the paste discharge opening 8; in the lid is uncovered vand brought to a position in advance of the front surface of the movable vane 35 discharge opening 8 to a position in which itis sealed or covered bythe bent-over portion 3b of the vane 3 so that the extruded paste is cleanly cutoif from the paste remaining in the box. Manifestly, the vamount of paste discharged at 45 any one operation depends on the extent of forwardturning movement imparted' to the lid.

In those cases where only a small quantity is to be discharged at any one time,"hardly anysuction arises behind the rotatable vane 3 and the 50k provision of an air inlet opening is unnecessary, but if desired, a small air hole may be provided tocounteract any suction effect that arises.

vAfterv `substantially one complete turn of the lid, the leadingedge ofthe vane 3lisbrought 55 into contact with the vane Il` and the contents of the box vhave thereby been completely dis'- charged. Upon turning the lid and the movable vane back to the original or starting position, the lid can be removed in order to charge the Xbox with a freshk supply. Moreover, the varies 3 and 4 can also be removed if required, as for the purpose of cleaning them and the*` interior wall of the container, means for rotating the a rotatable vane from the exterior of` the container, and means'for sealing and unsealing `the dis,- charge opening on opposite directional movements rof the rotatable vane. l l g 2. A paste dispensing device comprising an ,internallyv round container, 'a rotatable lid for the c ontainer having a paste discharge opening therein, a post xed -centrally in the container,

tworadial vanes extending one rotatably and the other nonrotatably from the post to the inner peripheral wall of the container, andmeans projecting inwardly from the lid for rotating the rotatable vane on rotation of the lid.

43. A paste dispensing device comprising an internally round container, a rotatable Alid for the container having a-paste dischargek opening therein, a post xed centrally in the container, two radial vanes extending one rotatably and the other non-rotatably from the post to the inner peripheral wall of the container, means projecting inwardly from the lid for rotating the rotatable vane-on rotation of the lid, and means for sealing and unsealing the discharge opening on opposite directional movements of the rotatable vane.

4. A paste dispensing device according to claim 2, the rotatable vane having a bent-over portion adapted to cover anduncover the paste discharge opening on initial turning movements of the lid in opposite directions.

5. A paste dispensing device according to claim 3, the rotatable vane having a bent-over portion adapted to cover and uncover the paste discharge i opening on initial turning movements of the lid in opposite directions.

6. A paste dispensing device comprising an .internally round` container, a rotatable lid for the container having a paste discharge opening therein, a post xed centrally in the container, two radial vanes extending one rotatably and the other nonrotatably from the post to the inner peripheralV wall of the container, the rotatable vane having a slotted, bent-over portion for seal ing and unsealing the discharge opening on initial turning movements of the lid in opposite directions, and a pin on the lid engaging the slot in said bent-over portion for rotating the `rotatable vane on` continued turning movement of the lid.
