- GOLLAP SIBLE TUBE FOR PASTE.

Specification of letters Patent.

Patented May 22, 1917.

Application filed September 16, 1915. Serial No. 50,979.

Essex and State of New Jersey, have 1nvented a new and Improved Collaps ble Tube for Paste, of which the following 1s a full, clear, and exact description.

This invention relates to collapslble tubes for holding paste material.

The invention has to deal more particularly with means whereby the external s1 1r face of the tube can be printed in a plurality of colors expeditiously, accurately and economically.

Heretofore in printing collapsible tubes in several colors great care was necessary on the part of the operator to so place the tubes on the printing mandrel as to 1nsure proper registration of the successlye impressions. Considerable tlme and Sklll is required to properly place a tube on a mandrel, so that the cost of prmtlng has been unduly large because of the limited number of tubes that can be printed 1n a given time according to the oldmethod,

The object of the present 1nvent1on 1s to insure a proper placing of a tube on the mandrel so that successive colors w ll abso lutely register, this registerlng-insurrng means being so designed that the attendant does not have to be especially skilled or experienced, as the mere placing of the tube longitudinally on the mandrel and turnmg the tube back or forth will interlock the mandrel and tube, the interlocking means being so designed that the tube can be locked to the mandrel in only one position, so that the successive impressions or colors must register. By this means the outp1 1t of the printing machine is many tlmes increased over the old method of operation.

For a more complete understanding of the invention, reference is to be had to the following description and claims taken 1n connection with the accompanying dravvlng, wherein similar characters of reference indicate corresponding parts in all the vlews, and in which- Figure 1 is a side view of an empty collapsible tube with a portion broken away to show the lug on the internal surface of the H. NEIDLIN-- GER, a citizen of the United States, and a resident of East Orange, 1n the county of head that engages with the mandrel to cause proper positioning of the tube;

Fig.2 is an enlarged transverse section on the line 22, Fig. l; v

Fig. 3 is an enlarged sectional view of the tube mounted on the mandrel and receiving an impression from the printing element;

and

Fig. 4 is a fragmentary detail view of a modified form of the invention.

Referring to the drawing, A designates a collapsible tube for holding paste stock, the tube comprising a pliable body 1, which,

when empty, is open at the end 2 and has a comparatively stiff head 3 provided with a discharge nozzle 4. On the head 3 and disposed internally of the tube is a suitable means adapted to interlock with the mandrel that supports the tube during the printing of matter onthe circumferential external surface ofthetube. Thismeansis preferably a lug 5 which is so shaped as to enter a recess or socket 6 in the end of the mandrel B of the printing machine. The. tube A is interlocked with or keyed to the mandrel by slipping the tube longitudinallv on the latter and turning the tube in one direction or the other while maintaining an inward pressure on the tube so as to cause the lug 5 to enter the recess 6, and when this is effected, the tube will be in the proper position to receive an impression. This act is repeated every time the tube is placed on the mandrel to receive another impression of color, and since the tube can have only one position on the mandrel it follows that all the impressions are positively registered. The lug 5 may be of any desired shape, and if desired the lug may be placed on the mandrel, as indicated at 5, Fig. 4, and the depression or recess 6 may be arranged in the head of the tube.

In Fig. 3 the printing element C is shown in the act of printing an impression on the tube, which is rotated with the mandrel.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of'operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the article Which I noW consider to be the best embodiment thereof, I desire to have it understood that the article shown is merely illustrative and that such changes may be made When desired as fall Within the scope of theappended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A collapsible paste-holding tube hav- 'ing on the inner surface of its head means for interlocking with the mandrel of a printing machine to insure registering of successive impressions printed on the tube.

2. A collapsible tube for holding paste,

com-prising a body, a head on one end thereof, a discharge nozzle at the center of the ing machine to insure registering of impressions successively applied to the external surf-aceof the body.

3. A collapsible tube for holding paste or the like, comprising a tubular body, of round cross-section, a head at one end of the body, a discharge opening at the center of the head, and integral means on the internal surface of the head for interlocking With a mandrel of a printing machine for insuring registering of successive impressions.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
