Abstract
A system for disposal of dangerous sharp articles and dangerous liquids, particularly those which represent the waste in certain medical procedures, includes an inner container and closure means and an outer wide mouthed, necked container whose receiving opening is closed against removal of material by a tapered, preferably conical insert which is divided into flaps and alternative covers, one to facilitate separation of syringe needles and thin barrels and the other to lock the outer container closed.
Claims35
A disposal system for dangerous materials comprising in combination:
- a container having a receiving opening and defining a support portion,
- a thin walled closure element having a first portion supported by the support portion of the container and having a second portion extending into the container through the receiving opening, the second portion of said closure element being cut to form at least a pair of resilient inner flaps, and
- a cover supported on the container for closing the receiving opening,
- the container and the cover having detents engageable with each other to retain the cover in locked relationship on the container.
1 more element
In a system for disposing of dangerous materials including a syringe having a needle portion:
- a hollow container,
- a cover for the container, the cover being formed with a through entry opening;
- and
- needle removal means in the form of a pair of jaws mounted on said cover and pivotable relative to each other for grasping the needle portion of the syringe when the needle portion of the syringe extends into said through entry opening.
1 more element
In a disposal system:
- a substantially rigid outer container having a receiving opening;
- a substantially pliant inner container disposed within said outer container and having an upper opening accessible through said receiving opening;
- inner container closure means disposed in said outer container and operably coupled to the inner container for closing the upper opening of the inner container;
- outer container closure means carried by said outer container and operably coupled to the outer container for closing the outer container;
- and
- means disposed in cooperative relationship on the outer container and the outer container closure means effective upon closing the outer container to prevent its being reopened.
3 more elements
In combination for disposing of dangerous medical objects,
- a hollow container having a neck portion and having an opening in the neck portion for receiving the dangerous objects, the container having an enlarged portion extending upwardly from the neck portion and having an opening communicating with the opening in the neck portion,
- a closure element having a first portion supported by the enlarged portion of the container and having a second portion extending downwardly into the opening in the neck portion in a direction progressively restricting the dimensions in the opening in the neck portion, the second portion of the closure element being slit to define flaps, and
- a cover disposed on the container for an interlocked relationship with the enlarged portion of the container and constructed to cover the closure element in such interlocked relationship.
In combination for disposing of dangerous objects,
- a hollow container having a hollow neck portion extending upwardly from the container and defining an opening at the upper end of the neck portion,
- a closure element having a first portion supported by the neck portion, the closure element also having a second portion extending downwardly into the neck portion in a frusto-conical configuration, the second portion being slit to define flaps, the closure element being made from a resilient material to provide for the pivotal movement of the flaps downwardly upon an insertion of the dangerous objects into the container and to provide for a return of the flaps to their original positions after such insertion, and
- a cover disposed on the container for covering the opening in the container in an interlocked relationship with the container.
In combination for disposing of dangerous objects,
- a closure element made from a resilient material and having a first portion outwardly disposed and shaped to provide a retaining function, the closure element having a second portion integral with the first portion and extending in a frusto-conical path from the first portion and defining an opening in the frustum of the cone, the second portion being slitted in the second portion to define at least a pair of flaps constructed to pass the dangerous objects in the direction of the decreasing opening in the cone but to oppose the passage of the dangerous objects in the opposite direction through the cones,
- a hollow container having a neck portion at its upper end, the neck portion defining an opening for receiving the dangerous objects and for passing the dangerous objects into the hollow container, the neck portion of the hollow container being shaped to retain the first portion of the closure element in fixed position and to provide for an extension of the second portion of the closure element into the neck portion, and
- a cover operatively coupled to the container to fit over the neck portion of the container in interlocking relationship with the container.
