This invention has general reference to machines adapted for formation, application and sealing of bottoms and tops to preformed container bodies or units; and it relates, more particularly, to machines for producing paper, fiber or analogous material containers.
Fundamentally the present invention aims to provide novel means whereby bottoms and tops are applied to and sealed in paper, fiber or analo gous material, tubular body shells or units to constitute leak-proof containers of predetermined capacity.
Another object is to provide novel means whereby paper, fiber or analogous material end discs having a thermoplastic coating on one face and .the surrounding edge, or which have a cellophane or similar material facing, or a fusible enamel, are inserted and'sealed into corresponding material body shells or units, having an interior coating of said thermoplastic, by coalescing union.
A further object is the provision of means which takes a cellophane faced paper strip, punches out a cup-shaped bottom for pressure into a container body shell with applied heat and then spins over the confronting end "edges to efiect fused union of said parts; whereupon the container thus formed is automatically filled and similarly closed by a correspondingly-formed top.
Other objects and advantages, more or less ancillary to the foregoing, and the manner in which they are realized in practice, will be apparent from a more complete examination of the following description, which, considered in connection with the accompanying drawings, sets forth a practical embodiment of the inventive features.
Generally stated, this invention consists of the novel devices, combinations of means, and arrangements of parts hereinafter disclosed, illustrated by the drawings, and more definitely expressed in the claims at the conclusion hereof.

Application March 20, 1936, Serial No. 69,805 I body portion ready for insertion of an end piece.
Fig. VIII is a similar view to the previous figure of a combination bottom-advancing rotary heater head including means for inwardly-retroverting or spinning the container end into sealing en-' gagement with the inserted bottom.
Fig. IX is a like view, showing a modified form of rotary head more particularlydesigned to exhaust air pressure from within the container, after being filled, as the closure or top is applied and forced into sealing position with concurrent spinning of the container top edge inwardly; and, Fig. X is a sectional detail illustrative ,of the sealed joint effected by the means of the preced ing figure.
Referring more in detail to the drawings, the' various devices schematically indicated'in bracketed Fig. I are all adapted for embodiment in conventional multiplex end-inserting and containerfilling machines; accordingly, it is deemed unnecessary to herein specifically illustrate such a machine, as all who are acquainted with the art willreadily appreciate their relative arrangement and operative coordination. 9
In Fig. I, an open-ended pre-cut section of paper, fiber or analogous material, tubing is designated by the reference character I, the same having its inner surface coated with a suitable thermoplastic, such as synthetic-resin. This section or container body shell I is appropriately moved into registration with a stationary heating head 2, either by elevation of. the former or descent of the latter, such head being preferably.
of the form shown in Fig. VII, for. the purpose of somewhat softening the thermoplastic inner coating 3. From the heating head 2, the section I passes to a bottom-feeding and placing mechanism, comprehensively designated as 4, and in: cluding a reciprocatory slide 5 adapted to feed a suitably faced paper, fiber or analogous material, disc bottom 6, Figs. VIII-X, or a similarly faced and peripherally-flanged bottom 1, Figs. IV and V, from a storage 8 thereof. As shown in Figs. IV and V, the bottoms I are of cup-shaped diametric cross-section. Each bottom 6 or I is individually.
and consecutively transferred from the storage 8 into theconfronting open end of a tube section I, whereupon an associated plunger 9 presses said bottom partially thereinto, as shown in Figs. VIII and IX, for a purpose later. on more fully explained.
The tube section I with the partially-inserted bottom 6 or I next moves into registration with a rotary combined inserting and spinning-head III to eifect full insertion of said bottom with concurrent inward-retroversion of the tube end as indicated at II, whereby said retroversicn is sealed into overlapping relation with the bottom outer peripheral portion and the adjoining inner face of the tube section end, as shown in Fig. X; or into similar lapping relation with the surrounding bottom flange l2, as indicated in Fig. V. Consequent upon insertion of either form of bottom 5 or 1, it will be readily understood that, incidental to the applied heat, the interior thermoplastic coating 3 will be partially displaced inwards by the advancing "cellophane" facing I3 of said bottom, and thus form a surrounding fillet-union l4 with the coating 3, in an obvious manner. It is also to be remarked, at this juncture, that during the full-insertion and end spinning operation just described, the open or upper end of the section or body shell I is moved into engagement with a discous head l5, Fig.
, and IX, or a plurality of same whenmore than one punch is provided, at a predetermined location in the container wall, for a purpose hereinafter set forth.
The bottom 6 or I having been inserted and sealed in the tube section I, as aforesaid, to form a container unit hereinafter designated as 23,
the latter is inverted by suitable turning means 24, Fig. I, and progressed to a filler 25, of that fluid, oleaginous product, or any other substance or composition of matter, said container is intended to hold. From the filler 25, the container 23 is suitably transferred to a second head 2',
for heating the interior coating around its top, whereupon it is moved to registration with a topfeeding and placing mechanism 26, corresponding to the'bottom mechanism 4 previously described. This mechanism 25 includes a slide 21 for transferring successive tops l8, individually, from a storage 23 into the province of a plunger 29, whereby the top is pressed part-way into the registering fllled container 23, in an-obvious man ner. From the mechanism 25, the container 23 passes to a rotary combined inserting and spin-v ning head Ill, Fig. VIII; or it may be to a vacuum spinning head 30, such as shown in Figs. IX and X, as later on further amplified. Either of the spinning heads I3 or 30 efiects secure closure and sealing of the filled container 23 with incidental formation of a fillet-union I4 as before described, to complete the cyclic operation and provide the sealed container 23. In association with the top-feeding and placing mechanism '26, there may be provided a suitable stamping device 32, for impressing on the top exposed face an appropriate marking 33 as to the character of the container content.
Referring now to the prefered type of heater head 2 or 2', as illustrated to best advantage in Fig. VII, the same comprises a body portion 34 having a tubular attaching section 35, and a cupped extension 35 of an internal diameter to snugly receive the tube section I. Interiorly of the cupped-extension 36 is a disk 31', of suitable material, having its peripheral edge tapered, as shown at 38, for beveling or flaring the confronting open end of the tube section or body shell I, as previously indicated by the reference l'l, Fig. VI. The disk 31 is, conveniently, held in place intermediate a flanged holder 39 hous ing an annular electric heater 40, by means of a clamp washer 4i and screw 42 threadedly engaged at 43 into the body portion 34; and said heater has wires 44 in circuit with a suitable source of electrical current. The wires 44, pref erably, pass through holes 45 into the tubular attaching section 35; and it is to be observed the flanged holder 39 is of an outside dimension for free passage within the tube section or body shell I, whereby the heat conducted thereby from the annular heater 40 radiates radially within said body shell to the confronting coating 3. In addition, there is suitably mounted on top, or at the back, of the body portion'34 a second or discous heater 46 with an insulating material covering annulus 41, through the bore 48 of which and tops .are of the type shown in Figs. IV and V, use can conveniently be made of the radiator type of heater 50, indicated in Figs. II and III, said heater embodying a spiral coil 5| so that its heat is evenly diiIused over the face 52 oi said heater. With this form of heater 50,. which is diametrically larger than the tube section or body shell I, it will be readily understood that all of the heating is effected by radiant action, rather than by direct contact heating as is in part effected by the cupped wall 35 surrounding the tube end in Fig. VII.
Referring now to the rotary end-inserting and spinning heads iii, In, shown to best advantage in Fig. VIII, each of the same comprises a body portion 53, having an attaching section 54, and cupped extension 55, substantially conformative with the disclosure relating to the heating heads 2, 2'. The cupped extension 55 diiIers materially, however, in that it is provided with an interior concentric embossment 55 having a peripheral ridge 51, with one or more inner ridges 58, one only being shown, which serve to impinge and support the disc ends 5, I3 during insertion into the tube section or body shell I and keep them level, or in correct planar relation with respect to the wall of said section. It is also to be particularly observed that circumambient to the 1 embossment 56 there is formed a groove 59 affording, in'conjunction with the 0uter.tapering edge of the ridge 51, a return bend 50 functional there is provided a disc heater 45a, having con-' ducting wires 49a and a covering annulus 41a oi insulating material, all as described in connection with the showing of Fig. VII. The wires 49a, however, in thiscase, pass through longi- 75 tudinal grooves 6l in an insulating material sleeve 62, clamped to the attaching section. 54 by a lock nut 63, and respectively connect with spaced stationary slip rings 6i, having electric conductors said rings being supported by the sleeve 62, in accordance with known practice. It is also to be noted the head it] is, preferably, provided with a vent passage 66 for relief of air pressure, as the container 23 is moved into registration with, and engagement by, the cupped'extension 55 of said head.
The vacuum type of inserting and spinning head 30 shown 'in Figs. IX and X substantially conforms to the disclosure of Fig. VIII, accordingly all parts corresponding thereto have like reference characters applied with the distinguishing exponent "b, in order to avoid unnecessary repetitive description. It is, however, to be observed that the spinning head 30 is formed with a solid attaching section 54b, having an angled passage 61 in communication with a diametric passage 68, or a plurality of radial passages, in turn having the ends 69 passing .through the wall of the cupped extension 55b with outlet apertures 10 thereinto. Fitted into the upper end of the attaching section 54b, as by a coupling gland H, is a pipe 12 connecting with any suitable exhauster means, not shown, whereby air pressure from within the filled container 23 can be drawn out through the vent orifice 22, or vent orifices when more than one is provided, by way of the apertures 12, and passages 69, 68 and 61, in an obvious manner. Incidentally, the inner surface of the cupped extension 55b is provided with a surrounding groove I3, into which the apertures 10 open, in order that the exhausting of thecontainer entrained air pressure is properly accomplished irrespective of the position of the container 23 relative to the head 30 circumferentially.
In the forms of tube sections I and container upper ends 23, shown in Figs. VII-X, inclusive, the same are each depicted as being optionally provided with an inwardly directed rib 14, lo-
, cated proximate the point whereto the bottom and top discs 6, l8 respectively are pushed to form the fillet-unions or sealing joints I; while said ribs also serve to prevent,the discs 6, is from being forced too far into the tube sec- .tions I.
From the foregoing disclosure it is thought the invention will be clearly understood, and its advantages appreciated, and while the description is necessarily of a detailed character in order to properly set forth the invention, it is to be understood that the specific terminology is not intended to be restrictive or confining. Furthermore, it is also to be borne in mind that various other arrangements of parts and modifications of structural details may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed.
