rlhe apparatus disclosed is designed fory the assembling and filling of bi-compartmeiit collapsibletubes,xwhich may include the outer collapsible tube ypart 15 andthe inner collapsible tubel part 16. The holders 14 are adaptedy for the i support of the Vouterr tube vpart 15,y While the inner tubepart 16 is vinf serted directly through the bottom of the AVouter tube part by operation ofthe apparatus asV more fully described below.
The apparatus may be provided with a lilling head 17 and this head is provided With a illing nozzle 18 communicating'with a filling tube 19 to Which-the InateriaLmay befed as, for example, through a flexible piper.
leading from a reservoir or other source of supply. rillie filling nozzle 18 is adaptedI to enter and partially iill each of' the outer collapsible tubes-15 as they. are carried` by the conveyor underneath said nozzle in a manner which will; be understood in the art.. Theamount of paste or other material; delivered to each tube 15 Will ordinarily be governed by mechanism carried by the apparatus.
VAs. sbown,` the b'lling head. 17 may also carry a mandrelorplunger 21 spaced aixed distance from# the illing nozzle 18 correspending` to the. spacing of the holdersV 14.
. rlhis` mandrel 21. provides. a support l'or the smaller inner tubes 16, and, is proportioned enter the inner tubes andW-hich communicates with aflexiblesupplytubef24- whichmay i lead to a1reser-voir or other source of supply,
diterent from that to which the `ieX-ibletnbe V20:.l`eads. Itwill be -understoedlthat the -filling mechanism for the inner tubes may beregulated so `as to insert a predetermined amount of matorialintothe inner tubeso as to fill it. toA a predeterminedv height Grdinarily, Whenthe two materials are thusfinscrted respectively into the outer and inner tubes and the tubes. are assembled as. described,` both tubesn'ill belillednearly full, buttsuiiicient Vtube material` Will be left extending above *the tube contents-sojthat the tube Walls can be readily rolled up by the usual `mechanism andthe assembleddouble tube: thus closed.
It will be clear from the abovedisclosure that, in the operation of the present apparatus, the nozzle 1S will be causedtoenter the successive outer tubes l'supported byy the holders lll'as the latter are moved'forwardly by the conveyor.` The nozzle is then operated to deposit in eachouter tube a` predetermined amount of paste or other material; the respective tubes ordinarily being thus about 40% filled. i
gazeuses The inner tubes lr6 formed substantially as shown in F ig. l may be slipped on the mandrel or plunger 21 by hand or by suitable apparatus (not shown), the neck 25 of the tune being disposed downwardly, as, shown. lt. will be understood thatthe mandnelanay be shpdand proportioned to lit rather snugly within the inner tube so as to support 'the latterand prevent its collapse or` deformation when itis-being inserted into the paste or. other material. already inserted into the y inthe construction disclosedthe,.1nandrel 23ras it descendt` with the inner tube carried thereby centers and accurately positions the respective tubes inside; thei outer: tubes 15. ls'oraiding in. centering` the two" tubes;A and maintaining themiin Aposition,theiinner and outer. tubes Ymay. be formed Witlrcomplemanf tary, formations :1s-morel fullyA described. be.: lowV andshown in, Eig. 2:, Whenthaoutel' andi inner. tubes. havel been; assembled; as de: scribed; the; conveyor,A- carried, the. b; c om partment assembled; tube underneatlr the rilling -head22xandits iilling nozzle 2,.which latter thenreadily enterstheg inner tube, 16.. l'aste on other material; which. isordinarily differenti frointhatfinsertedanthe outerstube, wall' thus. be y insertedf throughthe nozzle. 23 into. the innen tubeV to fills tbel salmeA toi. the desined; predetermined: amount; Ther adj a: cent ends of the tube constitutingthexbottom of the" bi-oompartment collapsiblev tube .Will then. be 'rolledi together. or.y otherwisel sealed in. any preferredmannenl According tothe modifiedlormof. the inL ventiionv shown in Fig-e 2, the; mandrel 26 corresponding tothe i mandrel 21, above de@ scribed, isprovided: at vitsleading. end Withfa depending pin or projection 27. relatively positioned so as to enter the neclfor.v nozzle 25ct the innerY tubefl.

The neck 25. preferably descends. into. thel internal cavity 28 formed' in thel neckV off the'- outer tube. The :neck: ofthe1 outerV tube may also be formed adjacent said cavityf28 with an annular shoulder. or seat. 29Lonto-which fits Vthe supportsO carried adjacentrthe neclof the` inner: tube. .TheseV1 supports.. may bein the form i of radi alf spaced# armsv or` projections i According to the disclosure otFig.l 3,*a-.bicompartment collapsibleV tube of the nature hereinbefore `described maybe filled byrmeans of' al modified procedure. AsV shown, this tubeina-y'comprise an'innertube 31, andfan outer tubeV 32v may bey concentricallyf..y assembled with thef centering' arms 381 engaging the shouldersv 34v in. amanner similar` to tube, the cap 35' cap 37.
. that described in ttnaetttm with Fig. 2. In carrying out the procedure of filling this partiallyunscrewed as shown so as to provide/a passage 36 around the end of the nozzleof the inner tube. n of a given nature is then filled down through the inner tube 31 by any suitable means as, for example, by means of the filling nozzle 23.
After a predetermined amount of material y has thus passed down into the inner tube and out through its nozzle and through the passageway 36 into the inside of the outer tube, then a material which may be of a-different i nature is inserted into the inner tube either through the same filling nozzle 23 or through a different nozzle as may be desired. Part or all of the first material may be displaced from the inner tube into the outer by insertion into the inner tube of the second material. It will be understood that .theV first kind of material will preferablybe entirely forced and displaced from'the inner tube as describedk whereby, when the *filling` of the tube is completed, the outer compartment vwill contain only the first material and the inner compartment will contain only the second material. compartment tube is collapsed the two different materials will be extruded together throughthe neck or nozzle.
Inthe further modified form of the invention shown in Fig. y4, which is generally similar to that described in connection with that of Fig. 3, but in this case the cap `37 is left screwed up into place on the outer tube, while the inner tube is lifted somewhat from its final -position in the outer tube. Thisdisplacement of the inner tube may be either accomplished by hand or by a suitable means not shown, so as to provide a passage 38 between theend of the inner ktube neck and the While this passage exists the material is fed down through the inner tube, throughV the neck thereof, and through said passage 3S into the inside of the outer tube.
In this manner a predetermined amount ofy material of a given nature may be inserted into the outer tube, whereupon a second materialV of a different naturemay be inserted into the inner tube. Y l
It will be understood that asv described in connection withFig. 3, the first material may be entirely forced from the inner tube, and it may be `displaced therefrom by insertion of the second material so that the inner tube contains only the second material when the filling f operation is completed. The material may in `this case as in that previously described be inserted into the inner tube in any desired manner. t
Since certain changes in carrying out the v above process and in the constructions set forth, which embody the invention may beV made without departing from its scope.,it is of the outer tube may be Paste or material Thereafter when the bi-k ing drawing shall be interpreted as illustrative 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 featuresof the invention herein described, and all statements of the. scope of the invention which, as a matter of language, kmight be said to fall therebetween.
Having described my. invention, what I claim as new and desire to secure by Letters Patent is p 1.
