Abstract

A tearable and disposable retainer for temporarily holding and positioning an apertured element such as a washer in place along the length of an elongated, generally cylindrical part. The retainer of the present invention includes a singular, generally planar member made from a manually tearable material. The retainer member defines a generally centralized hole or opening with a series of cuts or slits radially extending therefrom. A series of angularly shaped segments are defined between the slits, with each angularly shaped segment having a formed arcuate edge at a distal end thereof for frictionally engaging the outer cylindrical surface of the part over which the washer is loosely fitted.

Claims

1. A tearable retainer for temporarily retaining and positioning a washer along the length of a threaded element, said retainer comprising:

a generally planar member formed from a manually tearable material, said member defining a generally centralized circular opening whose periphery is defined within the periphery of said member, said member including a plurality of equal length slits cut into said member, and wherein said member further defines a plurality of arcuately formed segments defined between adjacent slits at the periphery of said opening for slidably engaging an exterior surface of said threaded element beneath said washer thereby retaining said washer along the length of said threaded element, and

wherein at least one major surface of said member includes adhesive for releasably holding a stack of members in an overlying relationship relative to each other prior to use, said adhesive permitting removal of one of said members from the stack.

2. The tearable retainer according to claim 1 wherein the material said planar member is formed of is paper.

3. The tearable retainer according to claim 1 wherein said member has a generally circular periphery.

4. The tearable retainer according to claim 1 wherein each slit has a length ranging between about 25% to about 33% of the diameter of said member.

5. The tearable retainer according to claim 1 wherein said member defines four equally spaced slits extending radially away from the periphery of said opening.

6. The tearable retainer according to claim 1 wherein said planar member has a material thickness ranging between about 0.003 inches and about 0.007 inches.

7. A retainer for retaining and positioning an apertured element along the length of an elongated generally cylindrically shaped member, said member comprising:

a generally planar member made from a manually tearable material, said member having formed therein a generally centralized circular opening extending through said member for allowing said member to be slidably positioned anywhere along the length of said cylindrically shaped member, wherein said member includes a series of cuts intersecting with and radially extending substantially equal lengths away from a periphery of said opening towards a periphery of said member for facilitating tearing of said member from about said cylindrically shaped member, and

wherein at least one major surface of said member includes adhesive for releasably holding said members in an overlying relationship relative to each other thereby forming a stack of members, said adhesive permitting removal of one of said members from the stack.

8. The tearable retainer according to claim 7 wherein the material said planar member is formed of is selected from the class consisting of:

paper, plastic, nylon.

9. The tearable retainer according to claim 7 wherein said mepmber has a generally circular periphery.

10. The tearable retainer according to claim 7 wherein each slit has a length ranging between about 25% to about 33% of the diameter of said member.

11. The tearable retainer according to claim 7 wherein said member defines four equally spaced slits extending radially away from the periphery of said opening.

12. The tearable retainer according to claim 7 wherein said planar member has a material thickness ranging between about 0.003 inches and about 0.007 inches.

13. The tearable retainer according to claim 7 wherein indicia is imprinted and positioned on one major surface of said member for indicating where to exert a pulling force on the member to effect efficient tearing of the member from about the cylindrically shaped member.

14. A tearable retainer for temporarily retaining and positioning a washer along the length of a threaded element said retainer comprising:

a generally planar member formed from a manually tearable material, said member defining a periphery having at least three corners, said planar member being further characterized by a generally centralized circular opening whose periphery is defined within the periphery of said member, said member further including a plurality of equal length slits cut into said member, with each slit intersecting with and extending from the periphery of said centralized opening toward a corner on the periphery of said member, and wherein said member further defines a plurality of angularly shaped segments defined between adjacent slits at the periphery of said opening, each angularly shaped segment defining an arcuate engaging surface at a distal end thereof for slidably and fictionally engaging an exterior surface of said threaded element beneath said washer thereby retaining said washer along the length of said element.

15. The tearable retainer according to claim 14 wherein said member is formed from paper having a material thickness ranging between about 0.003 inches and about 0.005 inches in thickness.

16. The tearable retainer according to claim 14 wherein the periphery of said member has four corners thereon.

17. The tearable retainer according to claim 14 further including imprinted indicia positioned adjacent a corner of said member for indicating where to exert a pulling force on the member to effect efficient tearing of the member from about the threaded element.

18. The tearable retainer according to claim 14 wherein at least one major surface of said member includes adhesive for releasably holding said members in overlying relationship relative to each other thereby forming a stack of members, said adhesive permitting removal of one of said members from said stack with substantially no residue adhesive being left deposited on the major surface of the underlying member.

19. The tearable retainer according to claim 14 further including diverging crease lines radially extending from the centralized opening in the retainer for adding rigidity to the angularly shaped segments.
