This invention relates to a device for dispensing tooth paste or the like from a flexible tube.
An important object of the invention is to provide means for exerting pressure upon the side of the tube, which pressure is moved longitudinally of the tube while the tube is held relatively stationary.
A further object of the invention is to provide means whereby a single manually operated element may be employed to exert pressure upon the tube and to cover and uncover the tubular neck of the tube.
In its broadest aspects, this invention comprises the use of a dispensing handle and a roller for dispensing the wanted amount of tooth paste on a brush.
The invention will be better understood from the following description thereof with reference to the accompanying drawings in which:
Figure 1 is an oblique view of tooth paste dispenser and toothbrush cabinet;
Figure 2 is a frontal view of the invention with the doors open;
Figure 3 is a middle section showing mechanics thereof;
Figure 4 is an isometric view of the roller box and .pressing table thereof;
Figure 5 is an enlarged fragmentary longitudinal sectional view showing the structure of the cabinet cap in association with the discharge orifice in the container;
Figure 6 is a perspective view of a fork and roller; and
Figure 7 is a plan view of a rack.
A cabinet ID of plastic or other suitable material is provided to house the dispensing device in an attractive container.
Protruding from a slot l in front of cabinet I0 is a dispensing handle |2 having a grip l3 on the side thereof. As best seen in Figure 3, the dispensing handle I2 is pivotally attached to con tainer [0 at 4. Pivotally attached on the outward end of dispensing handle I2, as at i5, is a valve rod |6 extending downwardly to actuate a rocker arm I! which is pivotally attached to the container l0, as at l8. The other end of rocker arm I! rests on a cap arm l9 which is also pivotally attached to container II), as at 20. On the other end of cap arm l9 is held a cap 2| for engaging the top of a tooth paste tube.
The inner end of dispensing handle l2 has a curved portion 22, to the end of which is attached a spring 23, said spring having its outer end attached to the front wall of container H], as at 24.
The curved portion 22 of the dispensing handle l2, when pivoting at l5, is brought to bear on hollow tube 25' pivotally attached at l8, pushing the upper end of the tube 25 upward and the lower end downward. A spring 3|, the outer endof which is attached to container I!) at I9; is attached at the upper end of fork 26. Fork 20'is attached to roller 2| by means of axle 25. The fork 20 is carried by a rod 20, slideably mounted within the tube 25'. The protruding ends of axle 25 are inserted in slots 26 on both sides of roller box 21. Roller box 21 is hinged onto a stationary incline table 28 at 29.
A spring 32 has one end attached to upper end of roller box 21 at 34 and the lower end is attached to cabinet ID by means of a thumb screw 35.
The flexible tube A containing the tooth paste or th like has its tubular neck inserted through the opening 36' of a cabinet cap 36 which is removably mounted upon the cabinet and which carries the cap arm l9. This cabinet cap is now mounted upon the cabinet and the tube A is supported by the stationary incline table 28 and is held in place by the sides 21. The spring 3| now retains the roller 2| in the raised position adjacent to the upper closed end of the tube A. The cap carried by the tubular neck 33 of the tube A has been removed and the cap 2| is now covering this tubular neck. When the outer end of the lever 2 is depressed, the link I6 and associate elements will shift the cap 2| from over the tubular neck 33. When the lever I2 is depressed its inner round end engages the upper nd of the tube or lever 25, swinging the same upwardly and swinging its lower end longitudinally of the tube A. The roller 2| is therefore moved downwardly and longitudinally of the table 28 and tube A. The axle 25 is guided in the slots 26, and the spring 22 forces the roller 2| into pressing engagement with th tube A. As the fork 20 is shifted longitudinally of the table 28 the rod 20' slides longitudinally within the tube 25' and remains connected with this tube. It is thus apparent that the upper portion of the flexible tube A is compressed or flattened and the paste forced from the tubular neck 33. When the lever I2 is released, the parts return to the normal position as shown in Figure 3. The slots 26 are curved upwardly at their upper ends so that the roller 2| may rise when it reaches the upper ends of the slots 26. This will insure the roller being above the upper end of the tube.
Having described the invention, what I claim is:
1. In a paste dispenser, a cabinet provided with an opening, an inclined table positioned within said cabinet for supporting a flexible tube provided with a tubular neck and containing paste, the tubular neck on said tube being arranged so as to extend through the opening in said cabinet for the egress therethrough of the paste, cap means mounted for opening and closing movement relative to said neck, and means operatively connected to said table and actuabie from without said'cabinet for dischargingthe paste through said tubular neck, said last-named means comprising a tube mounted for pivotal movement about a horizontal axis, a rod mounted for slidable movement within said. movably-mountedtube, a roller carried by the free end of said rod engaging said flexible tube, and a handle mountedfor pivotal movement about a horizontal. axis. andv bearing against said movabi'y mounted tube.
2. In' a paste dispenser, a cabinet provided with an opening, an inclined table positioned within said cabinet for supporting. a flexible tube. provided with a tubular neck and containing, paste, the tubular neck on said tube being arranged: so as to extend through the opening in said cabinet for the egress therethrough. of the paste, cap means mounted for opening and. closing. move,- ment relative to said neck, andmeans op eratively- REFERENCES CITED The following references are of record in the file of, this patent:
