I s'renons 'ro oswneo FALLS conromr TION OF NEW YORK ION, or rumor, NEW YORK, A coaroaa EXTERIOR SLIP COVER FOR CONTAINERS Application filed February 15, 1927, Serial No. 168,385.
The object of this invention is the production of economical improved slip covers for tainers; and further objects and the detaiied nature of the invention will be readily understood by those skilled in the art in the light of the following explanations of the I accompanying drawings that illustrate what.
we now believeto be the preferr d mechanicalexpression or embodiment our mven- .1 tion from among other forms an steps within the spirit and scope thereof.
The invention consists in certain novel features in structure and combination as more fully and particularlydescribed and specified hereinafter, v
Referring to the accompanying drawings forming part hereof Fig. 1 shows our improved cover' inside elevation on a'container. Fig. 2 shows the cover and a portion of the container in vertical section. 1
Fig. 3 is a detail enlarged side elevation of the cover. Figs. 4 and 5, show apparatus in vertical section illustrating various steps in the method of producing our said covers. Fig. 6 is a vertical section on an enlarged scale showing a portion of the completed cover before removal from the die or form in which the exteriorpaper band and the drawn flanged paper cap are assembled. The frictionv slip paper or like material ficover of our invention consists of a flanged paper imperforate disk 1, having an approximately smooth-surface cylindrical annular flange 2, and an exterior unbroken non-ex- ,pansible concentric strong paper or like inaterial cylindrical band 3, surrounding the flange 2, the disk and exterior band constituting a united permanent assembly.
Although it is perhaps diflicult to so illustrate by drawings, the cap 1, 2, is drawn from a flat .circular'disk 1, of relatively thin flexably strongly constructed g 'gebured overlyible cheap sheet paper, while the unbroken band or cylinder 3, is preferably relatively thick in radial cross section and relatively.
ing sheet paper plies or of secured sheet paper laminations. length are usually composed 01E1 cross sections cut from elongated tubes ma e on suitable paper tube winding'or forming machines by spirall paper y convolutely rolling a sheet of paper into a number of spirally wound convolutions adhering together to form a strong tube that can be severed transversely into strong stifl' bands 3. y i In the completed slip cover, the lower edge The bands 3, of the desired} and pasting together several an s or of the surrounding band 3, is preferably'approximately flush with the-lower edge of the disk flange 2, and the length of the band is apv proximately equal to the length of the cylinrical POItiOIlyOf the disk flange 2 with the imperforate top wall-0f the cover formed by the disk, preferably flat except at its annular circumferential portion where it comes down;
to its cylindrical flange within the band, thereby giving the appearance of a coverwith an apparently dome shaped top, although we do not wish to so limit all features of our invention.
The end in view is to-produce a paper- Ina-- cover that is economical in cost and t'erial sli that can be economically made under quantity {production methods, and'yet a cover that is of suflicient stability as to form and of strength and durability for use in closing'certain kinds of containers, particularly one time use paper containers of exteriorly cylindrical formation or tapered paper containers, such as 4, Figs.
rim 5, although we do not wish to so limit our 7 invention.
The stilfl? strong encircling band 3, constitutes the backbone or stifl'ening frame or form structure of the completed staple cover, and
thereby enables us to empioy the more or less flimsy drawn flanged paper material disk '1. Such flanged paper disks are more or less flimsy and unstable as to permanence in form, particularly as the flange thereof tends to flare and return to the ori'ginalflat form of the paper sheet and this tendency is increased by the presence of moisture. Bycombining this flanged disk-with the retaining form 3, as a permanent part of the slip cover assem- 1 and 2, having an exterior cylindrical topband and the expanding tendency of the flange, as' the cap flange is contracted and the 15 hand expanded/by the method we follow in assembling the flanged disk-1, 2, and form constituting band 3. p For instance, Figs. 4, 5 and 6, more'or less diagrammatically illustrate mechanism that can be employed in the production of the slip cover 1, 2, 3.
' With reference to such mechanism, 10, is a suitable base or bed on which vertical cylinderor housing 13 is secured. The ring die 9, is carried by and depends in this cylinder 13, with a flat horizontal top surface of the bed 10, forming a floor a distance below the open lower end of the ring die 9. The cylinder 13, and the bed are formed to provide a horizontal radial passage or slideway through the cylinder 13, along the top face of the bed and diametrically across the lower end of the ring die 9, for slide 11. The end of this slide is formed with a circular vertical opening 8, extending completely therethrough, of approximately the same diameter as the internal diameter of the lower end of the ring die, and this opening 8, registers and is alined with the vertical axis of the ring die when the slide is in operatve position, i. e. at its limit of movement to the left in the disclosure of Figs. 4 and 5. This opening 8, forms a ring and forming die and a ho der for the paper band or cyhnder 3, into which the flanged paper ca 1, 2, is to be driven from the drawing ies and finally formed. To hold and carry the paper band 3, the ring die 8, in slide 11, is formed with a vertical cylindrical bore the internal diameter'pf which is equal to the external diameter of the band 3, so that the band can he slipped down ,into said bore from the. top with its lower edge resting onannular horizontal ledge .or shoulder 12, and with its upper edge flush with or below thehorizontal top surface of the portion of the slide that forms the ring die. The lower end .of the bore of ring (he 8, from shoulder 12, to the bottom face of the slide, is concentric with the portion of the bore above shoulder 12, and is slightly less in diameter, i. e. of a diameter to sha e the circumferential portion of the cover isk 1, 2, that extends above the band 3.
A vertical plunger 6, is arranged above in vertical alinement witlr ring die 9, and this plunger is formed to constitute the reciproeating die of asetof cap drawing dies, and
to cooperate with ring vdie'9,'in drawing the flat sheet paper circular disk 1, spanning and resting on the upper end of ring die 9, into flanged cap form. The lower end of the plunger 6, is of reduced cylindrical form 8, to annular concentric overhanging shoulder 7 to receive the ironed 'out and drawn flanged cap and drive the same-into the paper band 3, in ring die 8, and in effect constituting the cap flange shaping surface of said ring die 8. The drawing dies are formed to gather, compress, and iron out the surplus paper material due to flanging the disk 1?, to produce a smooth faced flange 2, and under. great ressure' to drive'and swage this flange into.
the band 3, and thus compress the same tightly thereinto putting the band under expanding tension. When the descending plunger completes its operation of driving and shaping the flanged cap into tlieband 3, the lower end of the plungerv forms and shapes the part of the capbelow the band'and presses the cap top between the parallel fiat end face of the plunger and top face'of the bed 10.
When the plunger has withdrawn on its upward stroke, the slide 11, is withdrawn from the dies, and the completed cover 1,
2, 3, is pressed upwardly fromthe slide and removed. Another paper band 3, is then positioned in the die 8, in the slide and the slide is then returned to operative position within the dies, as indicatedby Fig. 4," whereinthe slide is shown on its way back to operative position carrying a paper ring 3, in 1ts die 8.
What we claim is As anew article of manufacture, an exterior slip cover for paper other cans, con
sisting essentially of a relatively-flimsy pa-' per disk having a smooth surface ironed cylindrical flange, and a relatively strong stiff non-expansible paper band united to and exteriorly surrounding said flange and of approximately the same length as and tenni natingflush with the lower end of said flange, whereby said cover is adapted to slip on the exterior surface of a can. with approximate air tight contact to provide an approximate liquid tight can closure;
