  • Patent number: 4882116
    Abstract: It has become necessary to provide warning tags and labels on equipment such as point sprayers to protect the operators so that they will not be injured and to protect the manufacturer so that it will not be sued for product liability. Often such warning labels and tags have been attached to the packages or cartons in which the apparatus is shipped and they can become separated from the equipment so that a user does not see the warning. The present invention provides an integrally molded-in place warning label which is attached to an electric cord of an appliance, such as a paint sprayer which is molded to the electrical power cord and which can be molded to the cord at the same time that a stress release and a power connector plug are molded to the cord. The warning label may be made of the same material as a strain release device and may be made of a tough resilient material so that it cannot be torn or separated from the power cord once it has been molded.
