The spout consists in the present instance of a pouring member 14 and a threaded spout cap 15.

Referring now to Fig. 2 it will be'noticed that the neck 13 is of non-uniform diameter being bulged out adjacent the top as indicated at 16 to provide an abutment or shoulder 1?! beneath-which the -spoutfis "to {be en gaged. Atthe top a ledge18' xtending inwardly is or may be provided and .uponathis is or may be seated ,a gasketJ-Q. Tllopouring portion 14 of the'sl'poutis provided with i a downwardly extending;skint-Q1 ;adgpted{to pass over and about the enlarged pa rt 16 of the neck 13. The spout illustrated:jnflfig. 2 may be considered a blank for the reason that 5 its formation particularly of *the skirt portion is incomplete. The skirt ;is made with a thickenetldower part 22 which is j thicker than the anal thickness r the skirt when theassembling is complete, and, of

course, the skirt portion has to'fbe reformed into engagement with the smaller portion of the neck.

In accordance-with -niy present invention it is intended that the nozzle a fterbeing placed upon the neck of the can-will be moved relatively-with respect to a-niold by :pres

sure upon the surface 'a'bove the skirt and in the relative i movement of the;assembled can and spout with respeot tothis mold,

the skirt -will=be reformed into tight-bindin}: engagement with the spout.

' The mo'ld preferably consists of two pivotedl halves 3 1 and '32 pivoted at and '84 upon a suitable bed 85, These -mo'ld parts more tothe open pos tion shown in Fig 3 r and may be closed 'by'insertingthe can neck SllW11'111 Flg. 4. Vhenin the position:shown, in Fig. 4 the mold is in-operativeposition andthroughout the assembling action ispassiv e. The active assembling member is a between-them -to swingthem to :the position plunger or die 86 shown in 5,15 and T.

member-s31 and 32, the bed or table and the plunger-or die 36 are shown on'sthe drawing since 'it'is belier e'd :that these are all that is necessary to :an understanding of the present invention. 3 These-operative members can "of course be' illCOFPOIHiGtl -lll any suitable supporting and actuating meeha- Iiism. I, "however, gprefer to employ the mechanism of my Patent 91,444,418 {issued b ue i 9 I V It Wil'be noted'that themold' provides a passage of .annular form'about "the neck of' Qnly the mold the can in which maybe received the skirt of the spout blanln Referring to Fig. it will be noted that between the top surface of the mold at 39 and a lower point therein at 41 the mold passage is cylindrical. Below the point 41 the passage is constricted as indicated at 42. As the plunger or die 36 descends the skirt portion is first constricted or contracted by engagement with the curved connection 43 beneath the portion 41 of the mold. -T his curvature is substantially that gin the present'instaneeiofthe neok'il'3 in or beneath its-part of the enlarged-diameter. As 1 the .die or plunger descends it carries the nozzle and. can downwardly forcing the metal of theskirtfirst into the form shown in -F g., 6 andthen thins the metal as shown in Flg. 7, reforming the entire skirt by contraetin'g it laterally against the neck and also by flowing the metal axially as may be seen-by comparing Figs. =5 and 1 Theibottom of the passage between the neck and'the -mo'ld-isopen to permit extrusion. ofthe' metal as to anyexcess that may .be provided. 7'

- ,2. The method "of securing soft metalv spoutsto containerswhich comprises providing the=conta 1ner with a spout engaging portion of non-uniform thickness and the spout with the skirt adapted to embrace said portion, arranging the spout on said portion,

then applying axial pressureto the top of the skirt all around the spout and independently of the spout and forcing the skirt into a restricted passage and contracting said" skirt to engage behind or beneath a container part of larger diameter and then reforming the contracted portion of said spout skirt into tight engagement with the container portion of lesser diameter.
