6 Claims.
This invention relates to paper bottles and containers of the type shown in Letters Patent of the United States No. 2,267,993, granted to us December 30, 1941, and the method of attaching the metal rings, U-shaped in cross-section, for securing the parts of the bottle or container, and more particularly the invention relates to the mode of attaching the metal neck rings to paper bottles in which the paper body is folded or plaited to form the bottle neck and mouth.
Heretofore in attaching metal rings to paper bottles or containers for securing the parts tog'ether it was customary to secure the ring in place by spinning the edge of the ring into the paper, or by means of radially moving squeezing or expanding dies. These methods are not satisfactory for all purposes and cannot satisfactorily be employed on bottles or containers having folded "or plaited parts which the rings engage owing to the different thicknesses against which the ring is spun, squeezed or otherwise clinched. It will be apparent that where the paper of the bottle or container is folded or plaited the thickness at one section will be single ply and at the folded or plaited sections the thicknesswill be three-ply, and that therefore a metal ring cannot be uniformly applied by spinning or radial squeezing to clinch the ring in place at all sections without cutting into the paper at the folds or plaits or leaving gaps under the ring between folds or plaits.
The object of our invention is to provide a method of applying a U-ring to the paper body of a bottle or container by relative axial movement of a pair of die members, within which the ringis held, to cause contraction of the edge of the outer flange of the ring, as distinguished from contraction or turning in by spinning, or contraction by radially moving squeezing rings or jaws.
In carrying our invention'into efiect we force the outer edge of the U-ring' into a die memher having an inward contraction, preferably curved, whereby the edge of the'rin'g is circumferentially contracted while the paper body upon which the ring is to be secured moves in the same direction with and at the same speed as the ring, and whereby when the inturned edge of the ring touches the paper the contraction continues while the ring edge is extruded axially of the die member substantially concentric with the tubular pa per body forming a circumferential shoulder on the ring, whereupon extrusion ceases and the final movement of the male die member causes compression of the outer flange of the ring, the pressure being applied at the shoulder formed by the extrusion and the saddle of the U-ring, causing it to spread and clinching the paper between the shoulder and the edge of the inner flange.
The method is illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section on the line ll of Figure 2 of a form of die mechanism whereby the improved method of contracting and clinching of a U-ring may be effected.
Figure 2 a horizontal cross-section on the line 2-2 "of Figure 1.
Figures 3, 4, 5 and 6 are fragmentary vertical sections of the mechanism shown in Figure 1 illustrating successive stages in the contraction and clinching of the U-ring upon the neck of a paper bottle.
Figure-7 an elevation and part sectional view on an exaggerated scale illustrating the clinched ring on a smooth surfaced body.
Figure 8 an elevation of part of a bottle body or neck having a plaited surface and showing the flow of the ring edge down and between the plaits, and
Figure '9 a cross section on the line 9-9 of Figure'8.
Referring to the drawings, and more particularly to Figures 1 and 2, which illustrate a form of tool that may be employed for practicing the method of our invention, I indicates a cylindrical body within which slides a sleeve 2 having an inner bevelled edge 3, which engages the correspondingly bevelled edgeof four radially'set jaws 4. Sleeve 2 is shown as having two arms 5 in which a rod 6 is journalled and on which lever I is sleeved as seen in Figure 1. This lever is suitably fulcrumed for imparting reciprocating movement to sleeve 2 for'closing and holding the inserted. 40
the die for contracting and clinching the bottle The jaws 4 constitute the female member of or container ring. These jaws are normally held open to receive aring and slide against the undersideof flange 8 of the body I to set the jaws in' the closed operative position after a ring is inserted. For this purpose the jaws are provided jaws are machined to present when closed a short cylindrical surface l0 and an inwardly curving surface ll,Figure1. The upper sides of the jaws are be'velled to presentwhen closed a conical en- -receive the end of paper tube, 118;.
trance [2 for the paper tube upon which a metal ring is to be contracted and clinched. Between the under and upper surfaces I l--l 2 the jaws are machined to present when closed a short cylindrical surface IS. The flange 8 of the body I is bevelled as shown at M to correspond with the bevelled surface I2 of the jaws to present an extended conical surface entrance for the paper tube. Y i
Adapted to slide within the jaw-closing sleeve 2 is a cylindrical anvil I having a circular seating groove l6 for the U-ring ll, shown in Figures 3 to 5 before the contracting operation, and in Figure 6. at the finish of the contracting and clinching operation. In Figure '7 the ring L1 and paper ring and at exactly'the same rate of movement. This movement maintains the tube seated in the ring saddle; holds the ring seated in groove l6; and maintains guide 24 in position relative to the anvil extension 23 and paper tube l8 so that the paper tube above the ring flange 22 will have a solid backing or anvil to receive the pressure from the exterior, when the ring is being clinched. This movement of the tube, ring and solid backing causes the edge of the ring when it touches the paper tube to bend over the edge of cylindri- "cal surface [3 of the jaws 4 and extrude from the Ijaws concentric with the paper tube and in con- .tact therewith. This contacting of the extruded tube I8 are shown in exaggerated dimensions to.
more clearly show the cross-sectional configuration imparted to the ring and the bend to the paper tube at the finish of the contracting and clinching operation. Referring now more particularly to Figures 3-to 6 it .will beseen thatrthe saddle I9 of ring H" has a smallerradius than the seating. groove l6 of anvil .l 5' which results in a circumferential spacing between the inner flange of ring: Hand the cylindrical anvil wall 21 and which part of the anvil wall is circumferentially machined to form a seat for the laterally projecting flange 22 of the U-ring. The anvil I 5 projectsabove the seat for the ring flange 22 and is-tapered to form a conical guide 23 for the U-ring as it is dropped into position, and this tapered extension forms an anvil for the papertube guide 24 which has an internal taper to provide a close-"fit on the anvilj part/r123 while" permitting the rim of the guid'ej 24' to seat upon ring flange 22 to hold the ring: firmly upon the anvil seat as seen in Figures 5 and'6.
The anvil is provided 'with'a pair of lugs 25, Figure 1, between whicha' lever 26 is hinged by pin 27, and this leverissuitably fulcrumed' to impart reciprocating movement to the. anvil after the sleeve 2 has been'moved-and held in position for locking the jaws 4 in operative position. The tube guide 24 is illustrated as securedito the'end of a rod 28 which may be supported and moved in any suitable manner.
The operation for applying a ring to a paper tube is as follows, reference being had to Figures '3 to 6: The jaws t being in the open position of Figure 3 a ring I! is dropped upon the anvil with ring flange 22 resting on the anvil seat and the outer curve of" ring saddle. l-9 in contactwith the outer periphery of ringwgroove Hi. Sleeve 2 is then moved upward to closejja'ws 4 tothe position showninfFigure 4. Atlthi's stage and step of the method, the upper end of theouter flangeiof the Ul-ring; which flange is deeperthan the inner flange, fits closely within the cylindrical selctiontl! of the closed jaws 4, and the ring is thus ,settio As the; paper tube is inserted into. the die,vtheguide 24=-follows or moves with itto assist in causing the tube'to enter and-seat itself squarely within the full depth of the U-ring, and at the same time; the guide 24 is seated upon the ring fiange 22 to'hold the ring firmly upon the anvil to prevent its displacement as seen in Figure 5. The metal ring and paper tube are nowin position for the ring contraction and: clinching. The anvil I5 is nowforced up.- ward by means of lever 26, thereby forcing the Uf-rihg upward within thezdie and causing its outer flange to contract and; curve'inward as it engages the curved surface Il;of: the jaws '4,- and this upwardgmovement of theanvil carries the tube 18, and guide'124 upward along with thiezU- edge of the ring prevents further contraction of the ring by the curved surface II and therefore the further inward movement of the anvil effects a compression of the ring between the surface I I and ring groove Hi. This step forms the shoulder and sharp angle 29 on the outer flange of the ring, see Figure '7, which clinches the metal ring upon the paper-tube by compressing the paper circumferentiallyat a downward angle upon the shoulder 38 of the inner flange of the metal ring; If now thei-nward pressure of anvill5 is continued to the limit of its movement, as seen in Figure 6, the pressure applied on the shoulder of the outside flange ofthe metal ring will cause the ring saddle l9 to slide inward inthe anvil groove l6, and since the ring fiange'ZZ is firmly held to its seat on the anvil, the inside flange of the metal ring, which has no resisting wall dueto the clearance between it and cylindrical wall 21 of the ring groove IE; will bend inward forming a circumferential bead 29 which serves tostiffen the ring and provide a retaining bead'for the ordinary sealing disk which sea-ts againstthe'rin'g flange 22. To remove the paper tube-with its clinched ring from the tool the levers .1 and Marc operated toretractsleeve 2' and anvil l5, respectively, which'allows the jaws 4, to open and trees the clinched ring from the anvil l5 to permit extraction of the tube with its ring from the tool and retraction of theg-uide 24. The anvil I5 is then in the position shown in Figure 3 prepared to receive another ring whereupon the jaws are closed and the operation repeated.
In attaching and clinching, a ring upon a smooth surfaced paper tube as shown in Figure '7, the extruded part 3 I of the ring is formed into a short cylindrical section of reduced diameter. When attaching and clinching a ring upon a tube having folded or-plaited sections to form the neck of a bottle, as shown in'Figures 8 and 9, the extruded parts 32 form short bands which overlap the folds or plaits 3'3, and the sections 34 of the .ring flow inward off the curved surface H of the die jaws between the folds or plaitsuntil contact is made with the paper tube sections 35, whereupon the ring sections 3 curve parallel with the tube sections 35 'a 1 very slight extent governed by the depth of'the outer-flange of the ring and'the thicknessof thepaper at the folds or plaits'., This flow of,;the metal of sections 34 of the ring between the folds or plaits produces an inward curve at the intersection of ring sections 32 and 34*as seen; in Figure 9, and when the final vertical sjqueezeis imparted to the ring as in Figure 6; the ring sections 32 and 3.4 are pressed firmly against the respective paper tube sections 33 and 35', and continued'pressure' produces the-bead 29 as above described. a
