US Patent:

44643160, Aug 7, 1984

Filed:

Jul 23, 1982

Appl. No.:

6/401297

Inventors:

Thomas L. Michaels - Wonder Lake IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

B01F 304

US Classification:

261121R

Abstract:

A closure system for a non-refillable container is provided. In the system, an internally threaded cap is carried in threaded cooperation on the neck of the container. Removal of the cap from a capped container is prevented through a combination of locking lugs and camming ramps having end stops. Locking lugs can be either on the cap or on the container neck with corresponding camming ramps located, respectively, on either the container neck or the cap. The locking lugs radially flex over the camming ramps as the cap is screwed onto the neck and radially snap back when out of camming relation with the camming ramp. Removal of the cap is prevented by contact of the locking lugs with the end stops of the camming ramps when the cap is attempted to be removed.

Abstract:

A nebulizer is provided which includes a liquid container and a cap attachable thereto. The cap includes a outlet port for delivery of a nebulized liquid/gas mixture to a patient, a gas inlet, a venturi in communication with the gas inlet, a conduit through which liquid may be circulated in the cap and heated by an external heater, a liquid outlet adjacent the end of the venturi, so that the gas flowing through the venturi draws out the liquid, and a dial rotatable on the cap. The dial has windows which may be positioned over openings in the cap to allow air from the environment to enter the cap and dilute the gas to a desired concentration. The dial engages the cap securely once its position is set on the cap, so the gas concentration is not inadvertently changed during use of the nebulizer.
