@ch 31, 195@ D. LAMONDE PASTE DISPENSING MEANS FOR TOO'IHBRUSHES 2 sheets sheet 1 Filed Feb. 5, 1947 Inventor Delphis Lamonde D. LAMONDE PASTE DISPENSING MEANS FOR TOOTHBRUSHES 2 Sheets-Sheet 2 Inventor elphis Lamonde Patented Oct. 31, 1950 UNITED STATES PATENT OFFICE PASTE DESPENSING S FOR TOOTHBRUSHES 3 Claims.

The present invention relates to new and useful improvements in tooth brushes and more particularly to a tooth brush in which the handle constitutes a holder for a tube of toothpaste together with means whereby the contents of the tube may be supplied directly to the bristles of the brush in such quantities and at such time as the same is required.

A further object of the invention is to provide a tooth brush in which a tube of toothpaste may be removably connected thereto for sup-plying the bristles of the brush with the contents of the tube and including an adapter by means of which tubes having various types of threaded necks may be interchangeably connected to the brush.

A further object of the invention is to provide a tooth brush including a hollow handle for receiving a tube of tooth-paste together with a pressure plate mounted in the handle and a lever positioned outwardly thereof for extruding the contents of the tube into the bristles of the brush and. also providing means for locking the lever against dispensing movement thereof when not in use.

A still further object of the invention is to provide a device of this character of simple and practical construction, which is neat and attractive in appearance, efiicient and reliable in operation, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view.

Figure 2 is a longitudinal sectional view taken on a line 22 of Figure 1.

Figure 3 is a transverse sectional view taken on a line 3-3 of Fi ure 2.

Figure 4 is a perspective view of the pressure plate for dispensing the contents of the tube.

Figure 5 is a side elevational view of the brush head and hollow stem for connecting the same to the hollow handle.

Figure 6 is a perspective view of the adapter for connecting the neck of the tube to the stem of the brush, and

Figure 7 is a side elevational view of a tooth massager adapted for interchangeably connecting to the handle.

Referring now to the drawings in detail, wherein for the purpose of illustration 1 have disclosed a p f r embodiment of the present invention,

the numeral 5 designates a brush head having bristlest suitably carried at one side thereof, the brush head having a hollow shaft 1 extending rearwardly therefrom and formed with a longitudinally extending bore 8 which communicates with the bristles at its front end. The rear end of the stem 1 is externally thread-ed as shown at 9 for connecting to the front end of a hollow connector Hi which is detachably connected to the front end of a hollow handle ll by means of interrupted threads l2 constructed to effect a quick connecting and disconnecting engagement of the handle.

The rear end of the connector I0 is recessed as shown at l2 and internally threaded for" threadedly receiving an adapter [3 by the quick threads !4, the rear end of the adapter being formed with recesses l5 for receiving a conventional tool for facilitating threading of the adapter into the connector and removing the same therefrom. The adapter 13 1s internally threaded as shown at l6 for receiving the threaded neck I! of a collapsible tooth-paste tube l8.

Adapters having various types of threads It may be provided to accommodate various types of threaded necks on the tubes.

The tube I8 extends longitudinally in the handle II and engaging one side of the tube is an elongated transversely curved pressure plate I9 having internally threaded bosses 20 formed adjacent its front and rear ends and in which the inner ends of rods 21 are engaged. The rods project outwardly through openings 22 in the sides of the handle H for sliding movement therein. A longitudinally extending lever 23 is connected to the outer ends of the rods 2! by screws or the like 24.

The rear end of the lever 23 is bent laterally inwardly as shown at 25 and received in a, recess 26 at the rear end of the handle. Positioned in the recess behind the rear end 25 of the lever is a coil spring 2'l for projecting the lever 23 outwardly to relieve pressure of the plate 19 against the side of the tube.

The plate i9 is also formed with a locking lug 28 which projects outwardly through the handle I l by way of an opening 29. The lug 28 is formed with an opening 30 adapted to receive a locking bolt 3| carried by a slide 32 working in a longitudinally extending slot 33 of the handle. By moving the bolt 3| forwardly to engagement in the opening 30 in the lug 28, the pressure plate is is secured against movement by the lever 23 when the device is not in use.

In the operation of the device, with the parts 1 3 assembled in the position as shown in Figure 2 of the drawings and the lock bolt 3| retracted, the tube 18 may be collapsed by an inward pressure exerted on the lever 23 whereby to dispense the toothpaste into the bristles 6 of the brush.

The brush head and bristles 5 may be enclosed in a cover 34 when not in use, the cover being detachably connected to the front end of the connector ill by means of quick threads 35. The cover is formed with vent openings 35 to provide circulation of air in the cover to dry the brush.

The bottom of the handle is formed with a rounded longitudinally extending rib 3? conforming to the curvature of plate 19 whereby to completely collapse the tube over substantially its entire transverse area to extrude substantially all of the contents therefrom.

In Figure 7, I have shown a gum massager 39 embodying the principles of the invention, the massager being mounted on a hollow stem 38 attached to a connector 49 which may be connected to adentifrice bottle (not shown) in place of the paste tube.

In view of the foregoing description taken in conjunction with the accompanying drawings it isbelieved that a clear understanding of the construction, operation and advantages of the device will be qiute apparent to those skilled in this art.

A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment oi the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

1 A tooth paste dispenser including a hollow handle for holding a collapsible tube and having outlet means at the forward end, a pressure plate positioned in the handle longitudinally of the tube, an L-shaped lever positioned longitudinally at the outside of the handle, rigid bars slidable in one sideof the handle and connecting the lever to the pressure plate, a lateral guide at the rear end of the handle slidably supporting the rear end of the lever, and spring means normally holding the lever spaced from the handle and with the pressure plate released from the tube.

2. A tooth paste dispenser including a hollow handle for holding a collapsible tube and having outlet means at the forward end, a pressure plate positioned in the handle longitudinally of the tube, an L-shaped lever positioned longitudinally at the outside of the handle, rigid bars slidable in one side of the handle and connecting the lever to the pressure plate, a lateral guide at the rear end of the handle slidably supporting the rear end of the lever, and spring means normally holding the lever spaced from the handle and with the pressure plate released from the tube, and looking means carried by the handle and locking the lever against tube compressing movement.

3. A tooth paste dispenser including a hollow handle for holding a collapsible tube and having outlet means at the forward end, a pressure plate positioned in the handle longitudinally of the tube, an L shaped lever positioned longitudinally at the outside of the handle, rigid bars slidable in one side of the handle and connecting the lever to the pressure plate, a lateral guide at the rear end of the handle slidably supporting the rear end of the lever, spring means normally holding the lever spaced from the handle and with the pressure plate released from the tube, and locking means carried by the handle and locking the lever against tube compressing movement, said locking means being shielded by the lever.
