N'. 1.. a corpora- Application June 18,. 1931. Serial No. 545,202 3 Claims. (01- 221-80) This invention relates to a dispensing tube which is used as an ordinary collapsible tube and which includes an ordinary collapsible tube which is stiflfened by a coating or an outside tube of 5 material stiffer than the metal of the tube. A number of various substances can be used as the coating or outer tubing and it can be applied by brushing, spraying or dipping. I find that oel-.

luloid is the best material so far used and the dipping the tube in the celluloid. The tube is preferably coated as soon as it has been made and while it is still symmetrical. This coating holds the tube to its shape during the subsequent handling when filling and during transportation and selling.

The dispensing 'tube has an improved appearance over the ordinary metal tube because it can be made-all one color when using translucent or solid color covering or it can give a protective and reflective covering to a metal tube when the covering is plain or colored transparent material. In case the metal tube is printed upon or is ornamented the outer covering serves to protect the printing.

Another advantage otthis dispensing tube is that by applying a solvent to the covering when of celluloid, especially when the covering extends part way up on the inside or the tube, a per- Iectly tight closing is possible in the Iolding and sealing of the tube alter filling.

My invention also embraces the method of covering a thin collapsible metal tube with a stiflenor in' any other manner.

Atube to illustrate one form of the new article is shown in the drawing. Figure 1 is a view, one .half in section and-one hall in elevation, of a tube. Figure 21s a section on line 2--2 in Figurel. a

nozzle 13 having a discharge opening 14. The' nozzle is closed by a suitable cap (not shown) which is usually screwed down over the nozzle which is provided with a screw-thread 16 to re-' 'ceive the threads of the cap.

On the outside or this pliable inner tube 1' place another tube 1'1. The outertubeismade .oi'material stiflerthan the inner tuli and-is 66 more resistant to distortion or a permanent namost economical and quickest way to apply is by As an inner tube or member 10 I provide aappearance.

ture. Many materials can be used tor this "outer tube but I find celluloid an excellent material.

A thin outer tube of celluloid resumes its shape after compression and always presents a neat outside appearance even when the.inner or collapsible tube has but little material left in it. This is in marked contrast with the usually partially or nearly'empty collapsible tube as now made. It is misshapen and any directions or other printed matter on the. tube is so compressed and wrinkled as to be of no value. In my improved tube this is not the case. The tube'retains for the most part, a symmetrical form, and when the outer tube is afllxed to the inner tube it pulls it 1 out into shape after it has been squeezed. The outer tube 17' can be made as a separate tube and then placed around the inner tube 1 either in. the absence or presence of heat. The usual way is to spray the material on the collapsible tube 10 into a solution. Qelluloid 'after, say, two dippings provides a good outer covering on the inner tube. .This dipping is done while the inner tube is new and cylindrical. The outer tube can be carried over the shoulder 12 as at 18 and may also be extended over the thread 16 as at 19. I

The lower part i. the outer tube can be extended over for a short distance on the inside of the inner tube as at 20. This aids in sealing as the material can be treatedwith a solvent in 35 sufllcient quantity to provide a tight joint and seal when the tube is pressed flat and folded over after filling. ing, cover byapplying the cover to it by dipping The outer tube can be made as a separate article and then applied to the inner tube and in such construction it is held firmly in place by the fold at the bottom when the tube is closed and by the shoulder part 18 at the top of the tube.

A transparent outer tube either of clearor colored transparent nature or-one made translucent .gives a permanent protection against oxi- -dation or dulling of the metal inner tube and also contributes to the tube a pleasingrefiective The article is of a highly ornamental appearance.

1. A dispensing receptacle comprising a thin non-resilient collapsible tube oi metal and a second tube or celluloid aili'xed to the outside 01 the collapsible tube.- the celluloid tube causing the collapsible tube to resume'itsnormal when squeezing pressure is released, the collapsible tube thus forming. a lining to the resilient celluloid tube. v

A dispensing receptacle adapted to be collapsed for expelling contents comprising a tube or celluloid stiff enough to resume its shape after compression and an inner tube of thin non-resilient metal, said tubes being secured together whereby the celluloid tube causes said inner tube. to bedistended in normal condition and said, celluloid tube is shielded from contact withthe'contentsoi the tube. 3.A dispensing receptacle adapted to be cpllapsedtor expellin: contents, comprising a tube portion over the outer surface of which the celluloid tube extends whereby the outer surface of thewhole' article is continuous.
