1. Field of the Invention
The invention relates to a flossing device structure, and more particularly to a flossing device capable of forming orderly teeth shape.
2. Description of the Related Art
A flossing structure in conventional flossing devices is shown in
However, gingiva inside oral cavity is softer and exposed due to lack of protection structures. Consequently, while using the conventional flossing device, gingiva may be easily slashed by the sharped barb structure 31 to cause bleeding, and oral diseases may also rise since wound may be easily infected by bacterial.
How improving the foregoing problems become a primary issue in the invention.
Therefore, upon the foregoing problems of prior art, it is an objective of the present invention to provide a flossing device structure, wherein its end portions are formed with barb flossing structure having orderly teeth shape to supply effect of preventing gingiva from being slashed during usage.
To achieve the foregoing objective, the invention provides an improved flossing device structure having a main body. Two ends of the main body respectively have an end portion. Each end portion has two correspondingly side edges, wherein at least one end portion is disposed with a row of teeth portion. The row of teeth portion is formed by recessing several concave cavities along the side edge of the end portion, wherein each concave cavity is recessed toward a top end direction of the end portion respectively to allow the side edge of the end portion to form several hook portions reversely extended toward the top end direction of the end portion, and a top edge of each hook portion is leveled with the side edge. Each concave cavity has a bottom edge respectively, and the bottom edge is formed with a guide section near the hook portion.
Preferably, the row of teeth portion is formed on one of side edges of the end portion of the main body.
Preferably, the end portion of the main body that is not disposed with the row of teeth portion is disposed with two support arms, and a dental floss is connected to the two support arms.
Preferably, the row of teeth portion is formed at two side edges of one of the end portions of the main body.
Preferably, the end portion of the main body that is not disposed with the row of teeth portion is disposed with two support arms, and a dental floss is connected to the two support arms.
Preferably, the row of teeth portion is formed at one of the side edges of the two end portions of the main body.
Preferably, the row of teeth portion is formed at two side edges of the two end portions of the main body.
Further, each hook portion is a circular arc shape.
The detailed structure, operating principle and effects of the present invention will now be described in more details hereinafter with reference to the accompanying drawings that show various embodiments of the invention as follows.
The technical content of the present invention will become apparent by the detailed description of the following embodiments and the illustration of related drawings as follows.
With reference to
With reference to
The row of teeth portion 2 is shown in
With the shape and arrangement of the row of teeth portion 2, the user can handle the second end portion 12 that is not disposed with the row of teeth portion to stretch the first end portion 11 into the inter-teeth. By utilizing the hook portions 22 of the row of teeth portion 2 that shows the shape of barb relative to extraction direction, food residue within inter-teeth can be hooked by the hook portions 22 while withdrawing the main body 1, and food residue can be locked in the concave cavities 21 along the guide sections 23. Finally, food residue is brought out in accordance with withdraw of the main body 1. Moreover, the hook portion 22 is leveled with the first side edge 11. Although the hook portion 22 is the barb structure, a portion of the hook portion 22, which is in contact with the gingiva, is actually the first side edge 111 so that it may not slash gingiva due to its leveled shapes while using the invention for flossing. Therefore, wounds can be prevented from being infected by bacterial.
Next,
While the means of specific embodiments in the present invention has been described by reference drawings, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims. The modifications and variations should in a range limited by the specification of the present invention.
