ABSTRACT:
A self-sealing cap for squeeze-type containers formed from a moldable material which includes a body portion defining an opening therethrough. One end of the body portion is securable to the squeeze-type container and the other end of the body portion is extended into side walls and end walls which are connected together to form an extension of the opening. The side walls terminate into resilient lip portions which, in turn, terminate into sharp biting edges which are abutting to define a narrow slit. Upon the application of the squeeze pressure to the container, the contents move the lip portions away from one another to form an outlet and upon cessation of squeeze pressure on the container the lip portions return under normal permanent set to close the fit while biting off the contents.
