    Abstract

    A pull off pipe cap (1) that fully seals the end of the pipe or pipe fitting to protect the pipe during construction especially while pouring concrete foundations around pipes. The pull off pipe cap is easily found under poured concrete and is easily removed from the pipe or pipe fitting without a need for demolition of the concrete slab and excavation around the pipe.

    Claims

    1. A pull off pipe cap comprising: a tubular body having a perimeter wall; said perimeter wall having an inner surface, an inner circumference, an outer surface, a top edge and a bottom edge, the inner circumference being of sufficient size so that the cap fits over a pipe to be capped; and a circular-shaped pull off lid having an upper surface, a lower surface and a perimeter edge being removeably attached to the top edge of the perimeter wall, wherein said perimeter edge of the pull off lid is attached to the inner surface of the perimeter wall of said tubular body.

    2. The pull off pipe cap of claim 1 wherein: said pull off lid is attached to the perimeter wall by an adhesive.

    3. The pull off pipe cap of claim 1 wherein: said pull off lid is attached to the inner surface of the perimeter wall via a releasable attachment means.

    4. The pull off pipe cap of claim 3 wherein: said releasable attachment means is an adhesive.

    5. The pull off pipe cap of claim 3 wherein: said releasable attachment means is a scored line.

    6. The pull off pipe cap of claim 1 wherein: said pull off lid is attached to the top edge of the perimeter wall by an adhesive.

    7. The pull off pipe cap of claim 1 further comprising: a pull ring located proximate to the perimeter edge of the pull off lid.

    8. The pull off pipe cap of claim 1 further comprising: said pull off lid is attached to the perimeter wall via a releasable attachment means; and a pull ring located proximate to the perimeter edge of the pull off lid.

    9. The pull off pipe cap of claim 3 further comprising: a pull ring located proximate to the perimeter edge of the pull off lid.

    10. The pull off pipe cap of claim 1 further comprising: said pull off lid is attached to the top edge of the perimeter wall via a releasable attachment means; and a pull ring located proximate to the perimeter edge of the pull off lid.

    DESCRIPTION OF THE PREFERRED EMBODIMENTS

    (10) For purposes of describing the preferred embodiment, the terminology used in reference to the numbered components in the drawings is as follows: 1. pull off pipe cap, generally 2. tubular body 3. perimeter wall 4. inner surface of perimeter wall 5. outer surface of perimeter wall 6. top edge of perimeter wall 7. bottom edge of perimeter wall 8. pull off lid 9. upper surface of pull off lid 10. lower surface of pull off lid 11. perimeter edge of pull off lid 12. attachment means 13. adhesive 14. scored line 15. pull ring 15A. proximal end of pull ring 15B. distal end of pull ring 16. pivot point 17. rivet 18. integrated lid 19. pipe 20. flange 21. pipe fitting

    (11) With reference to FIG. 1-6, the pull off pipe cap 1 of the present invention comprises a tubular body 2 having a perimeter wall 3 having an inner surface 4, an outer surface 5, a top edge 6 and a bottom edge 7. A circular-shaped pull off lid 8 having an upper surface 9, a lower surface 10 and a perimeter edge 11 is removeably attached to the perimeter wall 3. The perimeter edge 11 of the pull off lid 8 may be attached to the inner surface 4 of the perimeter wall 3 (as illustrated in FIGS. 2 and 5). Alternatively, the perimeter edge 11 of the pull off lid 8 may be attached to the top edge 6 of the perimeter wall 3 of the tubular body 2 (as illustrated in FIGS. 1 and 6).

    (12) The pull off lid 8 may be attached to the perimeter wall 3 via an attachment means 12, such as an adhesive 13 (as illustrated in FIG. 6) or a scored line 14 (as illustrated in FIG. 5) that tears when upward pressure is applied to the pull off lid 8. A pull ring 15 is preferably located proximate to the perimeter edge 11 of the pull off lid 8. The pull ring 15 may be stationary or attached via a pivot point 16, such as a rivet 17, that allows the pull ring 15 to act as a lever so when a proximal end 15A of the pull off 15 is pulled upward, a distal end 15B pushes downward on the perimeter edge 11 of the pull off lid 8 breaking the attachment between the pull off lid 8 and the perimeter wall 3 off the tubular housing 2.

    (13) Alternatively, the pull off pipe cap 1 may have a tubular housing 2 with a perimeter wall 3 and integrated lid 18. The pull off pipe cap 1 is removeably attached to an end of a pipe 19 via a pressure fit and/or a temporary adhesive. A pull ring 15 allows the pull off pipe cap 1 to be pulled upward thereby breaking the adhesive seal or pressure fit between he pull off pipe cap 1 and the end of the pipe 19. The pull off pipe cap 1 may fit inside of the pipe 19 and have a flange 20 that extends over the pipe 19 or a pipe fitting 21 (as illustrated in FIG. 8). Alternatively, the pull off pipe cap 1 may fit over the pipe 19 or a pipe fitting 21 (as illustrated in FIG. 7).

    (14) The circular-shaped pull off lid 8 is preferably constructed out of metal to allow the pull off pipe cap 1 to be found using a metal detector. In addition, the circular-shaped pull off lid 8 may be colored to increase the visibility thereof.

    (15) It is to be understood that while a preferred embodiment of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and drawings.
