Definitions
- a tubular can body comprising a radially expanded central portion, a neck at each end of the central portion, and a radially extending flange adjacent each neck at the ends of the tubular member.
- a tubular, elastomeric member is positioned within a die-contained can body and is pressurized to mold the can body to the shape of the die. The operation forms a radially expanded can body, necks the can body adjacent the radially expanded portion, and flanges the ends of the body in a single operation.
- a tapered elastomeric mandrel may be utilized in place of the tubular mandrel, obviating the necessity of lubricating the mandrel and allowing the body to be axially extended so that the material from which the can is formed is altered in cross section both radially and axially.
- a structural groove, suitably positioned in the mandrel surface allows flanging to be effected at the upper end of the can body without damage to the mandrel.
- an expandable member may be substituted in place of either the tubular or tapered mandrel to form the can body through use of hydraulic pressure.
- One object which has long been pursued by the industry has been to manufacture a can having a satisfactory volume for product containment, a reduced quantity and weight of metal, and a sufficient strength to resist can well damage. This has been accomplished, to some extent, by the use of aluminum which, due to its ductility, may be drawn to such an extent that a can bottom can be formed integral with the body walls. Use of aluminum allows cans to be produced which have a minimum amount of metal in the walls and a large concentration of metal adjacent to and in the bottom for structural strength.
- a longitudinal section adjacent each open end of each can body is formed into a generally radially outwardly directed flange.
- the flange is provided on each open end so that a can end (top or bottom) may be mounted thereon in a well-known manner.
- can bodies are cut and seamed at that diameter.
- the flanges are then formed at the ends of the can and a 2-l l/l6 inch can end is suitably fastened to the flange.
- the ends When can ends are placed on a body formed in ac cordance with the prior art, the ends have diameters which are greater than that of the body so that the ends extend beyond the body walls.
- the can ends When two cans are placed next to one another, the can ends are in abutment and the bodies are spaced apart by an amount equal to the difference between the sum of the radii of the can ends and the sum of the external radii of the bodies, thereby resulting in a waste in storage space equal to the total separation between the external wall surfaces of the adjacent cans.
- Some aluminum cans having the previously described integral body are provided with a neck just below the flange to increase the wall strength of the can so that it will withstand the forces imposed when a can end is installed on the flange. This also allows a slightly smaller can end to be used, such as a 2-9/16 inch end on a 2-1 l/l6 inch body, and obviates the problem discussed in the last paragraph.
- the necks and flanges for these cans have been provided in two distinct operations, requiring two different machines.
- the present invention comprises a new can body which may be formed by novel apparatus in ac cordance with a new and unobvious method.
- a can body formed in accordance with the present invention basically comprises a cylindrical body which has been expanded throughout a majority of the length thereof to enclose a greater volume.
- the work cylinder usually connotes a body having a circular cross section, it is mathematically defined as, the surface traced by a straight line moving parallel to a fixed straight line and intersecting a fixed curve; the space bounded by any such surface and two parallel planes cutting all the elements.
- This definition includes bodies having circular, square, rectangular, hexagonal, etc., cross sections.
- a can formed according to the present invention could be expanded from an original diameter of 2-9/16 inches to 2-l H1 6 inches.
- the radial expansion thereof also results in a work hardening of the wall, thereby producing a stronger can body. Adjacent each end, the can body is maintained at its original dimension so as to form necks which serve to increase the can strength and reduce spillage during filling.
- Each end of the body, beyond the necks, is bent in a radially outward direction to create a flange for attachment of a can end thereto in a well-known manner.
- the can ends, which are rolled onto the flanges, are, in the above example, the same ends which would be required for a 2-9/16 inch can rather than those required for a 2-1 l/l6 inch can, thereby further decreasing the amount of metal required to form a can according to the present invention.
- This last feature also means that when the can ends are put onto the body, they will not have a diameter as large as the expanded portion of the body, thereby allowing adjacent cans to be more closely stacked together since the exterior surfaces of cans will be in contact throughout the expanded portions thereof and the cans will not be held apart by abutment of the ends. In other words, the external wall surfaces of the bodies will be in abutment, thereby resulting in a decreased storage space requirementfor a given number of cans.
- a cylindrical body is placed within a multi-part die having internal structure for producing the entire desired body shape, including the necks and flanges.
- a mandrel is placed within the can body and a force is exerted thereon which causes the mandrel to expand against the internal die structure so as to be formed thereagainst.
- the body is maintained at its original diameter by the die structure and the wall between the necks is expanded to the desired shape.
- the ends of the body beyond the necks are formed about the die necking structure into can end-receiving flanges.
- the mandrels When elastomeric mandrels are used to expand and reshape the can bodies, the mandrels must be manufactured so that they extend beyond one end of the die structure to provide sufficient material for radial expansion thereof.
- the provision of a compressible circumferential groove in the mandrel allows the mandrel to flow in such a way that it cannot reach behind the end of the can body which is to be flanged adjacent the end of the die from which the mandrel extends. If the mandrel could flow behind that end of the can body and come between the body and the die, it would prevent proper formation of the flange and the mandrel would quickly become damaged by the sharp end of the body.
- Expansion of cans in accordance with this invention allows them to be automatically tested for seam strength, eliminating the time and labor previously required to accomplish this result.
- this progressive expansion of the can body may, when certain materials are used, allow the body to be stretched in the axial direction, thereby allowing cans of a predetermined length to be formed from bodies which have been manufactured with a slightly shorter axial dimension. This, of course, results in a further economic benefit due to the reduction of metal required to form a can.
- the present invention produces a can body which requires less metal and weight in both the body and the ends than heretofore possible, while allowing'a larger number of cans of an effective diameter to be stored in any given area.
- theinvention allows the cans to be formed in a single step, thereby obviating the previous requirement for a plurality of machines to accomplish necking and flanging.
- the method of this invention may be used to form a very wide variety of can shapes and may be used with many presently known materials such as tin-free steel, tinplated steel, aluminum, etc.
- FIGS. 1 and 2 are elevations, partly in section, of two embodiments of structure which may be utilized to form the product of this invention according to the method hereof;
- FIG. 3 is an enlarged illustration of the product forming apparatus according to the embodiment of FIG. 2;
- FIG. 4 is a view, similar to FIG. 3, of a third embodiment of apparatus which may be utilized in accordance with the present invention.
- FIGS. 5 and 6 are illustrations of consecutive positions assumed by part of the apparatus of FIGS. 2 and 3 during operation thereof;
- FIG. 7 is a partial sectional view of an apparatus which is similar to that illustrated in FIGS. 2 and 3, having a modified die structure therein;
- FIGS. 8-12 illustrate various configurations into which cans formed by the present invention may be shaped
- FIG. 13 is an elevation of two cans formed according to the present invention and placed in abutment.
- FIG. 14 is a view, similar to FIG. 13, of cans formed according to prior art methods.
- a can body forming machine element 11 forms one station of a multi-station machine in which a large plurality of can.bodies are formed sequentially and/or simultaneously.
- the machine rotates about a vertical axis (not shown) which is coaxial with a fixed upper drum cam 13 and a fixed lower drum cam 15.
- a cam follower l7 cooperates with a cam groove 19 in the lower drum cam 15 to reciprocate a support member 21 relative to a multipart die 23.
- the support is moved into position to receive a can body 25 from any suitable feed means, such as a starwheel (not shown), when the support member 21 is in the lowered position shown in phantom in FIG. 1.
- a starwheel not shown
- An upper cam follower 31 cooperates with a cam groove 33 in the upper drum cam 13 so as to reciprocate a punch 35 through a support plate 36 and relative to the die 23.
- Cam groove 33 is so formed that punch 35 is reciprocated to the position illustrated in FIG. 1 and is then moved downwardly still further during the period in which the can body is to be formed.
- a pilot rod 37 is suitably fastened to the punch 35 and an elastomeric mandrel 39, which may be of any suitable material, such as rubber, is fitted over the pilot rod for close abutment with the punch as shown.
- the mandrel may be either bonded to the punch or held thereagainst by shrink-fitting it onto the pilot rod.
- the multi'part die 23 is formed, in the illustration of FIG. 1, with a circumferentially recessed portion 41, hereafter referred to as the expansion section," between radially inwardly directed portions 43 and 45, hereafter referred to as neckers.
- a pair of circumferentially recessed portions 47 and 49, hereafter referred to as flangers, are formed at each end of the die structure adjacent neckers 43 and 45, respectively.
- the mandrel acts against the body in, the areas of the neckers 43 and 45 to hold it tightly against them, thereby stretching the body throughout the area of expansion section 41 with a resultant reduction of the can body wall thickness and increase of the body diameter in that section. Since the portions of the body adjacent neckers 43 and 45 are fixed against movement by the mandrel 39, their thicknesses and diameters will remain unchanged. 1
- mandrel 39 will also tend to expand into the flanger 49, causing the lower end of the body to be formed around the necker 45 to create a lower flange thereon.
- the mandrel will also expand into the flanger 47, thereby forming a similar flange at the upper end of the body.
- a circumferential groove 51 in the mandrel 39 allows the mandrel to be compressed at the intersection of punch support 36 and die member 23 without allowing the mandrel to flow into the area behind the can body in the flanger 47. If it did flow behind the can, it would interfere with the formation of the upper flange and would eventually become damaged by the sharp upper edge of the blank. This problem is obviated atthe lower flanger 49 since the mandrel does not extend below the lower extremity of die 23 and it cannot flow into the flanger until the flange is formed.
- FIG. 2 it will beseen that the structure therein is similar in many respects to that previously described relative to FIG. 1.. Elements which are nearly identical have been provided with identical identification labels, preceded by the numeral 1, so that machine element 11 of FIG. 1 becomes machine element 111 in FIG. 2, etc. Therefore, only those structural elements which are, different from those described relative to FIG. 1 need to be described with reference to FIG. 2. i
- a mandrel 153 within the machine element 111 is formed with a tapered external surface of conical configuration which is truncated in the area of the groove 151.
- the mandrel may be fastened to the punch by any of the alternatives previously described relative to mandrel 39, but to illustrate a further alternative it has been shown to be fixed to punch 135 by means of a plate 155 which is fastened to the pilot rod 137 by any suitable fastening means, such as a bolt 157.
- the plate fits within a circular counterbore 159 in the mandrel 153 and, when the punch 135 is in the upper position, seats against the bottom of the counterbore.
- the can body 127 is not long enough to extend up to the upper end of the die when support 121 abuts the die.
- the mandrel 153 When the mandrel 153 is placed into the body 127, the bottom end thereof will abut the support 121.
- punch 135 As punch 135 is actuated, the mandrelwill hold the bottom portion of the body against necker to prevent movement of the body, in the manner previously described. Further actuation of the punch 135 causes the lower end of the mandrel to bend the bottom end of the body into the flanger 149; at the same time, the forces acting on the mandrel move it against the body 127 in the area of the expansion section 141.
- the mandrel Since the mandrel is conical in configuration, its contact with the body and the resultant reshaping occurs progressively upwardly so that the body wall becomes thinner and may, with suitable body material selection, become lengthened toward the upper end of'the die. Thus, it willbe seen, that the particular configuration of the mandrel described may cause the body wall to be reduced in thickness while being increased in length. Further, the configuration results in an ironing effect on the body so that no wrinkles can be formed in the expansion section. Now turning to FIG. 5, it can be seen that, as the mandrel 153 moves the can body 127 into the expansion section 141, the can body will be lengthened until the top edge thereof is coplanar with the upper end of the die.
- the circumferential groove 151 comprises an upper tapered section 161 and a lower tapered section 163 which are joined by a vertical section 165.
- the upper tapered section 161 and the vertical section 165 will have become compressed to form an horizontal section and the lower tapered section 163 will have become compressed so that the lower edge thereof will expand outwardly to the upper end of the can body.
- Still further downward movement of the punch 135 to the position shown in FIG. 6 will result in a complete closure of the groove 151 and an extension of the opposite sides thereof into the flanger 147 to form a flange on the can body 127 about the upper edge of the necker 143.
- circumferential grooves 51 and 151 are identical, as is their cooperation with the flangers 47 and 147, respectively.
- FIG. 4 a third embodiment of an apparatus which may be utilized in accordance with the present invention has been illustrated. Those portions of the structure which are identical to previously described portions have been given identical labels, preceded by the numeral 2, such that support 21 or 121 now becomes 221; further description of such identical elements is believed to be unnecessary.
- a punch member 267 is suitably fastened by any desired means to a sealed, flexible, diaphragm-like member 269 which, if desired, may be tapered in the same manner in which mandrel 153 was tapered, or may be formed in any other suitable shape.
- the member 267 may, if desired, also be reciprocable within the support plate 236 so as to increase the pressure within the flexible member. Further, the flexible member may be provided with a constricted portion 279 which will cooperate with the flanger 247 in a manner which is similar to that described relative to groove 151.
- FIG. 7 an embodiment of the invention has been partially illustrated in which parts which are identical to those previously described have been labeled with an identical label, preceded by the numeral3.
- a die 381 has been positioned for cooperation with a mandrel 353 to form a can body 327 in the manner previously described.
- the expansion area 341 has been provided with a plurality of recessed portions 383 of varying shapes and diameters, so that, as the can is formed, it can be embossed in predetermined areas through cooperation with the die 381.
- FIGS. 8-12 a variety of can sizes, shapes, and embossing configurations can be provided in accordance with the present invention.
- a can body 429 has been shown which is circular in cross section, having wall strengthening necked portions 487 which are equal to the original wall thickness and diameter of the can, and end flanges 489.
- the internal surface edge 490 of the necks serve an added function in that they reduce liquid splash and loss when the can is filled with the product at a later time.
- an hexagonal can 529 is shown having necked portions 587 and flanges 589.
- a square can body 629 has been illustrated having necks 687 and flanges 689. Obviously, in the case of such shapes, some reforming in the neck and flange area will occur, but. this will be negligible in comparison with the reforming of the intermediate section.
- FIG. 1 1 shows a generally circular can body 729 having necks 787 and flanges 789. As shown, the can may be provided with embossed portions such. as 791 and 793 which, for example, would correspond to the configurations shown in the recess portions 383 of FIG. 7.
- a can body 829 has been illustrated having necks 887 and 888 and flanges 889.
- a variety of different features may be provided in a single can body, such as a central constriction 891, longitudinal embossments 893, artistic designs such as an embossed shield 895 having cross spears 897 embossed upon the embossment, etc.
- the use of the apparatus and/or method of the present invention will provide relatively limitless configurations, dependent only upon the inherent limitations of the process and the design capabilities of its user.
- neck 888 has been expanded somewhat, whereas the diameter of neck 887 has been maintained at its original dimension.
- cans are formed in the shapes shown in FIGS. 8-12 with similar differences in neck and end diameters, improved stacking of cans will result since the smaller can ends, on the body ends having smaller neck diameters, will fit within the larger can ends on the larger necks.
- utilization of storage space can also be improved in this manner.
- FIGS. 13 and 14 there is clearly illustrated the storage advantage of the cans formed according to the present invention over the prior art.
- a pair of cylindrical cans 1029 are in abutment throughout the expanded mid-sections of their lengths and their can ends 1030 are held apart due to the configuration of the can necks 1087.
- the prior art cans 1088 shown in FIG. 14, however, are not in contact along the body walls but are separated by the abutment of the overhanging ends 1090.
- cans of a predetermined size e.g., 2-11/16 inches, which are formed according to the present invention, may be placed closer together than prior art cans of an identical size, thereby saving storage and shipping space.
- the invention herein provides a new and improved concept in the can-making art which yields a true advance in that art.
- the invention allows the production of can bodies in a highly economical way since the amount of material used in a can is reduced by means of a reduction in wall thickness, an increase in the length of the wall, if desired, and the use of smaller ends. Also,- the body is formed in a single operation, eliminating the need for a plurality of machines to perform necking and flanging in separate steps.
- the invention should not be construed so as to preclude the formation of the flange in a separate operation, if that should be desirable in certain instances.
