' This invention relates to tubes which serve containers for various materials thatiare tobe gradually used, the most common form of such tubes being the ordinary flexible tube having a cap closure at its upperl end and so constructed that when the cap is vremoved and the other end of the tube is squeezed 0r rolled up, the contents of the tube are gradufally forced out through the delivery'opening. @ther tubes are made to use the contentsrby tearing oif a portion of the delivery end of the tube adjacent to the contents to expose the contents, such tubes being usually usedonly with solid, or comparatively solid, contents. I In almost every existing form of tube for use with such things astooth paste, shaving cream, cosmetics, make-up materials for actors, etc., there is some objectionable feature in the provisions for gettingthe material out of the tube. In the ordinary squeeze or rollup form oi' tube there is considerable waste of materials which is left in the irregular recesses in the tube and in other forms of tubes there is usually more or less smearing of the An object of the present invention is to pro,- 'uvide an attachment for tubes which may be put on and sold as part of the tube structure itself and which will be an improvement over means heretofore known for effecting the removal of the tube contents. i

More particularly, the invention aims to provide means for causing the ejection of the tube contents which in itself will constitute a closure for one end of the tube and which .in its operation will sever a portion' of the tube corresponding to the amotuit of material rejected, thus maintaining the tubeconstantly full and of a length suitable to contain the re maining contents.

Other objects and important features of the invention will appear ,from the following des cription and claims when considered in con n nection with the accompanying drawings, in

which y Y Figure 1 isa view, partly in section, of an ordinary tube for paste or material of similar Y consistency, having a relatively small delivy ery opening normally closed by a screw cap end ,of the `tube 6 is con fined. rhe inner shell 192s. "s'eriai Np. 292,855. v and having the present invention' appliedto its other end; Y v 'f 'I Figure 2 isa view, partly in section-,illustrating the invention applied to a. tubeof the` same cross-sectional dimensions throughout its length and 'closed at .its vdelivery end byla slip-,on cap; Y

'Figui-e3 is aview somewhat 'similar to Fifgure 2 but showing a section'of the attachment n at right angles tothe section shown yin Figure 2 and having the ydeliver end of the tube pro-l vided witha screw-on cap and Y Figure 4, is a bottom plan View of the con'- struction; 1 For convenience in assembling the parts andin placing the attachmentin position on the tube, it is preferably made .of twovmain parts comprising anout'er lcylindrical shell Q and an inner shell 4 between which the lower 4 is provid ed with a screw thread?v of rounds ed crossesection so that it will not cut the ma# terial of the tube, and the outer shell 2 is'pro4- videdwith a protuberance Sfwhich fits 'into the depression betweenL the threads of the inner shell 4, the protuberance 8 being. also rounded andpreferably formed by indenting vtheshell2. g, ;l Y Upon the upper end ofthe inner shell 4 rests a washer or disk 10 which bears against' the ,under side of the .contents 12 of the tube, which contents may be in the form either of paste or of substantially solid material., In the drawings, the upperend of thea shell is also shown as closed at 14, but itwill be ob .sa vious that a complete or 'even partialrclosure of this end ofthe shell. is not necessary so long as suliicient bearing surface for the: washer 10 is provided. l y

' lnorder that the two shells may cooperate ac to push the, washer l0 up the tube and thus force the tube contents out of the upper end of the tube, the shells are connected together to turn together so that the screw thread formation on the innershell will cause the shells .9,5 totravel up the tube and theprotuberance 8 on the outer vshell 2 coopera-ting with the thread on the inner shell will form a thread in the tube as the shells travel upthe tube,

the tube being preferably made of materielle() adapted to be readily deformed. The illustrated means for connecting the twoshells together comprise lugs or proJections 16 extending from the lower edge of the inner shell 4 through openings 18 in the head of the outer shell 2 and upset or headed over the outer face of the outer shell.

It is obvious that the lower end of the tube must be disposed of as the connected shells travel up the tube, and to this end the attachment is providedV with cutting means which serve to trim oft1 an amount from the lower edge of the tube corresponding to the distance of travel of thetube. The illustrated cutting means comprises aknife blade 20 struck up from a steel disk 22 provided with openings 24 through which the lugs 16 extend so that the disk"y 22 is connected to the shells 2 and A to turn therewith. The knife blade 20 extends througharecess 26 in the inner shell 2 into the tube-receiving space between'the shells where it engages the tube and as the shells turn together and travel up the tube severs spirally from the lower edge of the tube a strip 28. The head of the outer shell is provided with an opening through which the strip 28 is vdischarged so that as the contents of the tube are used up and the material of the tube is cut away, the portion of the strip 28 that projects beyond the head of the shell 2'Inay be turned olf and thrown away, thus leaving the tube with substantially its original appearance except for its vertical height.

From the foregoing description it will be seen that by merely grasping the outside of the tubeand turning the attachment on its lower end, the desired. amount of the tube contents may be forced from the upper end without any apparent deformation of the tube and without liability of smearing the hands with the tube contents. Moreover, the tube itself is used up at fast as its contents and the contents can be more gradually removed than with the ordinary tube construction because of the greater control and therefore precision of the operation of the means for effecting ejectment of the contents.

When ,the tube is intended for paste, a form similar to Figure 1 may be used; when the contents of the tube are somewhat more solid, then either the form shown in Figure 2 or that shown in Figure 3 is preferable, in which the removable cap is of the same diameter as the tube so as to permit the contents of the tube to be moved bodily up the tube.

In lFigure 2 of the drawings, it will be noted that the inner shell 4, which serves as a plunger for forcing the material out of the tube, extends above the upper edge of the outer shell 2, thus permitting' the tube contents to be forced completely out of the tube whilestill leaving a sufficient portion of the tube to be gripped by the hand to permit relaattachment up the tive turning of the tube and the contents ejecting attachment.
