  • Patent number: 4520926
    Abstract: A container for holding sharp objects includes a bottle having a body and a rim extending upwardly from the body and defining an opening into the body. A cap is disposed upon the rim in abutting relationship to the rim near the bottom of rim. The rim and the cap define a detent relationship to hold the cap in irremovable relationship on the rim. A funnel made from a relatively soft and pliant material is disposed on the rim between the cap and the rim in sealed relationship with the cap and the rim. The funnel and the rim define a detent relationship to hold the funnel on the rim. The funnel is provided with a portion extending downwardly and inwardly into the opening in the rim at an angle to the rim. The inwardly extending portion is slitted to define a plurality of resilient leaves. The funnel abuts the rim and the cap along the side and top of the rim and the cap.
