Combination toothbrush and dentifrice dispenser – Christopher L. Taylor – 1957 – Patent: US2807818

Combination Toothbrush and Dentifrice Dispenser (1957)

U.S. Patent No. 2,807,818, granted on October 1, 1957, to Christopher L. Taylor, introduces a versatile, portable oral hygiene device designed for the modern traveler. Taylor, an inventor based in Los Angeles, California, sought to eliminate the bulk of separate brushes and tubes by creating a single, fountain-pen-shaped unit that could store and dispense any type of dental cleaner.

This specific invention solved a common frustration for mid-century commuters and travelers: the lack of a compact, leak-proof way to carry a toothbrush and various types of “dentifrice” (liquid, paste, or powder) in a pocket or purse without making a mess.

The Innovation: The “Universal Reservoir” System

Unlike previous “fountain” toothbrushes that only worked with specific pastes, Taylor’s design featured a tubular body (10) that acted as a universal dock for different container types. The brilliance of the system lies in its ability to adapt to whatever the user has on hand.

1. The Membrane-Piercing Needle (33)

For liquid users, the inner end of the brush head features a hollow needle. When a flexible liquid capsule (50) is pushed into the tube, the needle pierces a thin membrane, instantly connecting the reservoir to the bristles.

2. The External Dispensing Lever (57)

To apply the cleaner, Taylor installed a mechanical lever on the outside of the pen-like body.

  • Pressure Plate (58): When the lever is pressed, it pushes a curved plate against the internal flexible tube.
  • Controlled Flow: This “squeezing” action forces liquid through a flow channel (38) and out of tiny orifices (40) hidden in the center of the bristle bunches.

How the Apparatus Functions

The device is designed for a seamless transition from storage to active brushing:

StepActionPurpose
1. UncappingThe long top cap (20) is removed to reveal the bristles.Protects the brush from pocket lint and keeps it sanitary.
2. DispensingThe user tilts the brush down and presses the external lever (57).Forces liquid dentifrice directly onto the bristles from the internal capsule.
3. ReversingAfter wetting, the brush is tilted up.Allows excess liquid to flow back into the capsule to prevent drips.
4. VentilationThe cap is replaced; air flows through small perforations (59).Allows the damp bristles to dry, preventing mold and odors.

Technical Components

  • Bristle Bunches (36): Arranged transversely with outlet orifices of approximately 0.010 inch in diameter—small enough to prevent leaks unless the lever is pressed.
  • Retaining Fingers (41): Small, inward-directed metal or plastic tabs that “lock” the mouth of a liquid capsule in place over the needle.
  • Multi-Purpose Caps: The top cap features a pocket clip (28) for carry, while the bottom cap (24) holds the dentifrice container firmly against the internal needle.
  • Recessed Containers: For paste or powder users, the containers (60 or 80) feature a special recess (66) at the inner end to prevent the needle from accidentally puncturing them.

Versatility: Liquid, Paste, or Powder

Taylor’s patent emphasizes “market universality.” The dispenser is compatible with:

  • Liquid Capsules: Direct flow through the needle and bristle orifices.
  • Toothpaste Tubes: The user can detach the brush head and squeeze paste directly onto the bristles, or squeeze paste onto a finger to be transferred.
  • Toothpowder Containers: Features a rubber stopper (84); the powder is poured into the palm of the hand and the moistened brush is dipped into it.

About the Inventor: Christopher L. Taylor

Christopher L. Taylor was an innovator working in the post-war Los Angeles industrial scene. His design reflected the era’s obsession with “all-in-one” gadgets and the increasing mobility of the American workforce. By modeling the device after a fountain pen, he tapped into a familiar aesthetic of professional utility. Taylor’s work was a precursor to modern travel toothbrushes, but with a level of mechanical sophistication—specifically the integrated internal pump—that is rarely seen in disposable modern equivalents.

Summary of Claims

The patent explicitly claims:

  • An elongated tubular body with a pocket clip and ventilation holes.
  • A membrane-piercing member (needle) that establishes communication with a dentifrice capsule.
  • A pivoted dispensing lever and internal pressure plate for squeezing flexible containers.
  • Outlet orifices located specifically within the centers of the bristle bunches for direct-to-bristle application.
  • A modular design where the brush member (30) can be removed to accommodate paste or powder containers.
