To @222 whom, it may concern:

Be it known that 1, ROBERT A. Beer MANN, a citizen of the United States, and a resident of Newport, in the county of Newport and State of lthode Island, have invented new and Improved Clips for Closing Non-Metallic Collapsible Tubes, of which the following is a full, clear, and exact descri tion.

.L y invention has for its object to provide a clip for use in closin non-metallic collapsible tubes, which has ns serving to hold the tube in position when rolled- Additional objects of the invention will appear in the following specification in which the preferred form of my invention is described.

In the drawings, similar reference characters refer to similar parts in all the views,

Many attempts have been made to mandfacture collapsible tubes of other material than metal such as paper and celluloid, because of the excessive. cost of the manufacture of such tubes of metal, but a difliculty has been encountered in the manufacture of collapsible tubes of paper and celluloid and other materials, for the reason that it has been found t be impossible to roll the nonmetallic-tubes tightly, so that they will not spring open. When using collapsible tubes,

it is customary to roll up the end of the tube after the material contained in the tube has been squeezed beyondthe said tube end, and in the use of non-metallic tubes, this cannot be done satisfactorily, as the non-metallic tubes will spring open after they have been rolled, as stated above.
