Abstract
Abstract An endless article (10) for cleaning between teeth is disclosed as including a first segment (18) of an elastic material and also a second segment (20) of an inelastic material bonded together by their ends to form the endless article (10). The endless article (10) includes a directionally effective abrasive surface (14) and is graspable by a pair of hands. The article (10) is stretchable for proportionately reducing the cross section of the first segment (18) to position a section thereof between the teeth. A section of the article (10) is movable thereafter along its longitudinal axis (L) between the teeth for cleaning there-between.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
207 words
An endless article (10) for cleaning between teeth, comprising: an endless segment (12) of an elastic material and having a generally uniform cross section; said segment (12) having a directionally effective abrasive cleaning surface (14) including dimples forming rows (15) situated essentially perpendicular to the circumference of the article (10) to allow the article to be easily inserted between the teeth, said dimples also forming rows situated parallel to the circumference of the article to provide abrasion for cleaning as a section of the article is moved parallel to its circumference; said article (10) being graspable by a pair of hands; said article (10) being stretchable between a relaxed position and a stretched position for positioning a section thereof between the teeth; said cross section being proportionately reducible in area as the article (10) is stretched for facilitating positioning of the segment between the teeth; said cross section also being returnable to the relaxed position size as the article (10) is relaxed, said article (10) being movable between the teeth for cleaning proximal areas and also being repositionable in the hands to allow an unused section to be used for cleaning after a used section of the directionally effective abrasive cleaning surface becomes soiled or worn out.
