it invention relates generally 'toitoiletg articles, and moreparticularlyflo holders for collapsible metal tubes which are generally.v 'lized as containersffor' toilet creams, dent-al 1 ue, shaving creains and the like: 1

' vide a device which may be quickly and easily placed uponthe tube; which can gradually? be collapsed with the tube to efiect an etlicient. 1,5 and complete discharge of the contents thereand which, during such collapsing, will protect the tube' against breakage and willv becomejfirmly locked thereon, whereby accidental displacement is obviated, 20.

From a reference to] of thej drawings itwill be seenthat an elongated blank may tube towhichthe device is tobe appliedj I11 termediate these solid portions a portion 12 V a v is cut out, preferably in the torm'of {an 1* Another object of the invention" is toproshaped slot, leaving side straps 13, which a are ultimately preferably creased,;asshown indotted lines, andform a collar around one end ofithe tube. Also, at one endof the blank o another opening 14 similar in shapeto the opening-. 12 is cut out, leaving side straps 315 and an endstrap 16.

' {This blankthen is assembled in 'con- 7 '1 lapped by the end 17 ofthesolid portion ill,

suitable means, as, for example, by the metallic staple-clip 19. The sidestrapsliigand 15 I are flexible in the sense that; they allow the members 10 and l1 to be jsqueezed together. Suchfflexibility maybe accompli'shecbby creasing,as shown indotted li'nes in Fig. 1,

or by other suitablemeans.

After the'ends of, he blank weathered,- the tongue-portions 20 of the straps l and le arebent inwardly, whereupon the collapsible tube 21may; be inserted throughflone otthe openings 12 or 14 and moved longitudinally of the device until the shoulder-portionof the tube isengagedbyone pair ofside straps,

and the other pair engages theother endof H Either endof the tube may belfirst a inserted,[and i orthe sake of appearance, it

When-the 1 I CLGV'lCGlS positioned on the tube it willbe seen that the solid portions 10hr 11 thereof protect the flat sidesofthe tube from damage, and, since the device preferoverhangingedges of "the solidf'portions I10 ably is constructed wider than the tube, the

and the entire ensemble is adapted to fit snuglywithin a packing box of the usual type. I Because of the flexibility of the strap-pop ,tionsl3 and 15,'the sideportions l and 11 ofthe'device may be compressed inwardly against the tube to collapse the same and discharge the contents thereof and by progressively squeezing from the bottom of the tube-upwardly the ejection of the entire coni by reference to Figs. '5 and6, when the bot-' 'tom portionof the tube thus hasbeen collapsed,'fthe increase'd.-width,- due to flatten sing thereof, causes the protectivedeviee to "become firmly locked'thereon. Y

Although many desirable features of the present device will be readily apparentyit might'herebe pointed out that the use of the device comprising the present invention .casetvhen the tube is rolled-up, as is usually done 'durmg use, and, f desired, trademarks another advertising matter also may. be

protects the tube against breakage during use and allows printing of the name, label, trade mark, etc. of the contents, of thetube on thematerialused for making the device tions being always legible,;which is'not the printed on theside portionsof the device.

It might be pointed out also that the pres- I cut device can be stamped out of a sheetof material byadie in a singleoperation, readilyassembled and placed on the tube by an automatic machine after the filling and sealing of thetube are complete; and 1ts use W111 not require material alteration ofthe machines-now inuse in the industry.

above article and different embodiments of scription or shown in the accompanying drawingshall be interpreted as illustrative tube, comprising wall portionsiof semi-rigid and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all'of the generic and'specific features of the inventionherein described, :andall statements of the scope of the invention which as a matter of language might be said to fall therebetween. I
