ABSTRACT:
BACKGROUND OF THE INVENTION
Toothpicks are very old and have been the subject of patents for over a century. For example, U.S. patent to Briggs No. 2,760,628 granted Aug. 28, 1956 discloses a toothpick which consists of a body of thin and flexible plastic stock that is pointed at one end to provide a tip and has a longitudinal crimp extending substantially from end to end thereof but terminating short of the apex of the tip. Such a toothpick is longitudinally stiffened throughout the main part thereof, while its tip remains relatively flexible thereby enabling material costs to be held to a minimum and the toothpicks to have novel and advantageous characteristics.
More recently, U.S. patent to Varum, No. 4,998,978 teaches a cloth or plastic strip formed of crossed strands forming cross ridges in surfaces of a strip to produce a frictional scrubbing arrangement against teeth surfaces.
U.S. Pat. No. 3,954,115 to Bengtsson, granted May 4, 1976, teaches a toothpick having a channel-shaped cross-section tapering to a point, and a picking portion. Both portions are roughened along their sides and are partly roughened in order to provide an abrading surface.
It is also old and well known to provide flavoring to toothpicks, toothbrushes, etc.
SUMMARY OF THE INVENTION
Individual toothpicks as well as a packet of toothpicks, are made according to the invention.
Each toothpick has a handle portion and an embossed cleaning portion. The embossing renders the cleaning portion effective in cleaning between teeth and also provides pockets or grooves into which any suitable chemical such as flavoring may be placed.
The handle portion is thicker than the cleaning portion to provide strength.
The packet of toothpicks is made by a process which forms a sheet having a center portion and two outer portions. The center portion is folded onto itself so that half of that portion is contiguous with the other half. Therefore, the two outer portions are also contiguous with each other and ultimately are the cleaning portions of the toothpicks.
A cover having a side that may open and close encloses the above packet of toothpicks and has an adhesive for allowing the cover to be removably held in a closed position when the toothpicks are not being removed from the packet.
