This invention concerns a novel method and appara~us for aS selnbling such thin-walled container halves.
~, A particular object of the invention i~ to provide ~ novel apparatus employing a die member with a central opening in which one end provides a cylindrical portion having a diameter equal to the diame-ter of one of the halves a~d terminates in a stop shoulder at the bottom thereof, ~aid ~, cylindrical portion merging at the upper edge thereof with ih~ narrow end of a frustoconical pilot surface which guides th~ e~ge portion of the container half into the ~ylin~xical ~ortion. The opposite end of the die is formed with a ~rllstoconical necking-in surface which at its innex end is ;~ ~h_ radiall~ inner edge of the shoulder ag~inst ~hich the first end portion of the container rests. The shoulder has a xadial width slightly greater than the thickness of the ~orltainer wall seated thereon.
The first and second halves are advanced ~oward a~:h other at opposite sides of the die and the second hal~
is 'c'orced throu~h the necking surface and is sligh-tly necked irl while the first half is disposed in receivin~ position.
Thus, as the second half is being necked in, it al~o wedges into the first half. These operations ~re concurrent.
B~ore the halves are fitted one into the other, the' second or entryirlg half has a coating of adhesive applied thereto along its entering edge, although it will be under~tood the adhesi~e m~y be applied within the outer (first) cont~iner hal f at its jlmcture ed~e portion.
~n An important aspect of the invention resides in holdin~ the outer container round (s~uared) in the same fixture that the entering portion of the inner container is " slightly necked in and relatively advancing the two halves '' toward each other while hold;ng them under control so that ~, the inner container portion easily enters the open end of the C out~r portion. The inner portion is under corQpressio~ and after release from the die, springs outwardly and pxoc~uces a hoop tension in the outer portion.
.
These ~nd other objects and adv~n-tages i.nherent in and enco~lpas~d ~ the inven-tion will become m~re ap~arent from the specification and drawings, wherein:
Figure 1 is a side elevational v~iew par~ly in ~xial section of apparatus incorporating the invention;

DESCRIPTION OF T~E INVENTION
Describing the invention in detail as shown in the drawings, the apparatus l compri.ses a support ~rame 2 whi~h ~0 has a plurality of vertically aligned bearings 3 and 4 rnoun-ted thereon in which an operating shaft assembly 5 is journaled~
The sha.ft assen~ly is split into two counter-rotary sections 8 and 10.
Shaft section 8 is connected to one jaw o.r c.l~p hol~er 12 ~nd tlhe sha.ft se~tion l~ is conne~te~ to i~w or clamp holder l4 of a die 15. The jaw sections each carry a hal~
section segment 16 of a die rin~ 17. Each sect.ion 16 has a tongue 18 fitted into a groove 20 in the associated jaw or clamp holder 12 or 14. In addition, there is provided an r 30 and stop 22 àt each end of segment 16 abutting the eI~d o~ the same, the StQp bein~ attached by screws 24, 24 th.readed into the associated end portion of the jaw section 12 or 14. Jaws 12, 14 have arms 25, 26 respectively at one of their ends keyed by keys 27, 2B ~o the respective shaft sections B ~nd 3S lO.
The shaft secti.ons 8 and lO are connected to pis-tons 34, 36 of air or hydraulic motors 38, 40, the piS~OIlS
operati11g in cylinders 42, 44.

_a~_ ~ hlls, the clamps and thei.r associated die sections are opened and closed by reverselv turning the respective shaft sections in order to admit cup-shaped container halves or cups 45, 46 which are made of metal, preerably aluminum Qf about 6-10 mils in thickness.
Associated delivery and discharge mechanism is i used to bring the cups to the assen~ly app~ratus 1 and -to remove the assembled container but are of no con~ern as to iO the present invention.
As best seen in Figures 1 and 2, the assembly apparatus is provided with vacuum holders 4~, 49 which are mollnted on the frame and each have an arcuat-ely shaped pocket 40 Wit~l a vacuum slot 51 connected with an associated vacuum ~; 15 line 53.
The holders 48, 49 releasabl~ hold the upper and lower halves 45, 46 of the contaiIler with the open end por-tions 55, 56 ~Fig. 4) thereof facing each other. The clamps ar~ then closed about these open end port:ions as seen in the ~Q right half of Fig. 4. If desired, the clamps may ~irst be closed and ~he halves advanced toward each other and entered into the upper and lower ends of the die 17. It will be noted that the upper and lower end portions 58, ~0 of the dies are provided with truncated conical guide su~:faces 61, 62 w31ich fl~re do~nwardly and upwaxdly respectively and at their outer ends are of a diameter greater than that of the body portions 63, 64 of the upper and lower cup sections.
Thus, the edge portions 55, 56 of the bo~y portions 63, 64 are easily guided into the center portion of the die.
n The center portion of the die has an upper cylindri-cal die portion with a surface 67 which is equal to substanti~
ally the outside diameter of the upper cup. The upper cup is advanced into t.he surface 63 which rounds the lower edge portio~
of the upper cup by an upper pusher 70 which has a cap 71 at ~'~ the lower end of rod 72 of a piston which operates in an air cylinder 73 carried by the frame.
The llpp~r Cllp sli~s along the holder 48 and is g~lided into the cylindrical die sur.iace 67 until the ~ower edye 75 ~3 ~
of the llpper cup seats upon the shoulder 76 at the botto~l of the squaring surfclce 67. Simultaneously, with the uppex cup being inserted into the cylindrical secti.on 67, the lower Cllp is pushed upwardly by an air or hydraulic cylinder 77 which has a ~ase pod 78 bearing against the bottom or base 79 oL' the lower or male cup. The edge portion 56 of the lower ~up ~ has been previously coated with an appropriate ad~lesive 79.
The edge portion 56 of the lower cup is very slightly neck~ in '1~ but not deformed as it moves past the shoulder 76. The inner edge of the shoulder 76 is of a diameter slight~ less than the inner diameter of the upper cup, and the shoulder 76 has a radial dimension slightly larger than.the thickness of the metal of the body wall of the upper cup.
1~ It has been found that the fit of the lower cup edge portion into the upper edge portion merely springs the metal of the lower cup very slightly without permanent de.~or-mation and that upon release from the die, the hoop compressive ~orces on the edge portion 56 are slightly relieved and 0 t:ensile hoop stresses develop in the edge portion 5~. Thus, a tight fit is insured between the two halves and the adhesive ~ which is preferably thermoplastic polyolefin resins s~lch as carboxylated polypropylene or pol~ethylene as well as Lhermo~
'~ settiny r~sins such as epox~ resins. These resins, when '` 2~ h~atad, will distri~ut~ and bond in sh~r the opposing au'er surface 82 of the inner portion 56 to the inner surface 83 of the outer portion 55. It will be noted that no inner support is required to telescope the two cups into each other and no wrinkling occurs at the juncture so that a good, -leak-proo~
boncl is developed which resists separation of the two halves in sheam It will be understood that any cold adhesive or thermoplastic adhesives may be used to boIId the two halves.
After the two cup halves are assembled, the die is opened and the upper and lower pushers separated and a vacuum ..
s~ withdrawn from the holders and the assembled unit is withdra~n or drops out and the following two halves are entered into the apparatus at opposite sides of the die and asser~bled in a continuous process.

10. The invention according to claim 9 and applying an adhesive to either the inner side of the outer container end portion or the outer side of the inner container end portion or both, prior to telescoping them together to provide a lubricating medium therebetween, and after assembly heating the container to melt and fuse the adhesive to the respective end portions
