TECHNICAL FIELD
The present invention generally relates to a
particularly, to a seamless, drawn and ironed beverage container body having portions of a lateral wall expanded radially outward from an initial cylindrical configuration, and to a method and apparatus for expanding the side wall of the container body.
BACKGROUND OF THE INVENTION
The present invention relates to the reconfiguration of the side wall of a stretched and ironed seamless container body. Such container bodies are typically used for beverages and are constructed of a single metal disk, sometimes referred to as a model. Typically, e > The metal disc is an aluminum alloy. The metal disc is first formed in a cup having a wall portion at the bottom and a side wall extending from the bottom wall portion. Then the cup is stretched and ironed to axially extend the side wall and reduce the diameter of the cup »The treatment of stretching and ironing thins the metal in the side wall» The side wall of the body of the container formed in a treatment of styling and ironing has an initial cylindrical configuration, and extends from the portion from the bottom wall to a neck portion in an open or open part of the body the container opposes the portion of the bottom wall. The portion "J" of the neck is often tapered to include a portion of reduced diameter, and it is provided with an external directed tab rrnen t. The resulting finished container is sometimes referred to as a two-part container. That is, the body of the container, which was subjected to the stretching and ironing treatments to form the bottom wall portion and the side wall extending from the bottom wall portion, is the first container part, and a The end wall of the container, which is usually doubly stitched to a portion of the open end of the container body in opposition to the bottom wall portion, is the second part. Due to the large number of containers made each year, the beverage container industry is constantly striving to create two-piece containers with the minimum amount of metal »The metal container used to form the body of the container, for a container It has a thickness of approximately "0,0284 cm - 0-0289 cm." The side wall is thinned to about a third of the thickness of the initial disc, and another type of metal container commonly found is some Sometimes a three-piece container includes a first rectangular piece of metal which is rolled into a cylindrical configuration to form the side wall, or cylindrical portion of the container. welded together to form a seam along the side wall »The cylindrical portion of the three-piece container in this way has s open ends. A first end wall and a second end wall are then doubly stitched to the open ends of the cylindrical portion, such as the second and third pieces, respectively, of the three-piece container. Typically, the portion
A cylindrical three-piece container is many times thicker than the side wall. of a stretched and ironed container Various methods and apparatuses are known for reconfiguring, or radially expanding outwardly, portions of the cylindrical portion of the three-piece container. An apparatus is described in Japanese Patent Nos. 54-150365 and 54-168737. This type of apparatus includes a mandrel of internal configuration with a plurality of segments of rotation. The forming segments are cam-driven radially outwardly to engage with the inner surface of the cylindrical portion of the three-piece container and to expand at least a portion thereof radially toward it. exterior »Another apparatus for expanding portions of the cylindrical portion of a three-piece container is described in US Patent No. 4, 487.048 ("Frei") »Frei goes to the formation of eyebrows in the cylindrical portion of a three-piece container» As described in figure 1 of Frei, a cylinder is placed that has two open ends on a inner roller which is provided with raised projections. An axial movement of an expansion cone forces the projections radially outward into the cylinder. More recently, the cylindrical portion of the three-piece containers has expanded using an internal fluid pressure. The internal fluid pressure forces the cylindrical portion of the three-piece container radially towards it. outside in a mold or shell having a desired configuration for the container »fi difference of the cylindrical portion of a three-piece container, the container body of a two-piece container includes an integral bottom wall portion. The bottom wall portion inhibits the movement of the metal in the side wall and makes it extremely difficult to cold treat the side wall to expand it beyond the brittle one, and the side wall of the container body has limited ductility. Therefore, the expansion techniques used for the three-piece containers have not been used for a two-piece container body. A method of reconfiguring or expanding the side wall of a stretched and ironed container which is described in US Pat. No. 5,058,408 ("Leftault, 3rd and others"), describes heat treatment of portions of the side wall. In Leftault, 3rd. and others, heat treatment of the sidewalls of a stretched and ironed container was found necessary to allow successful bending of the side wall of the container. Otherwise, the bending operation could exceed the capacity of the metal forming and cause catastrophic failure. The heat treatment is applied for a sufficient time and at a temperature sufficient to decrease at least 15% the resistance to loosening of the side walls to allow subsequent bending. Portions of the side wall are preferably heated with a conventional heating induction coil at a temperature of about 232 ° -343 ° C, for a time of about 0.25 to 10 seconds. The heat treatment causes recrystallization of the metal in the side wall to a microstructure of very fine grain. After the heat treatment, the side wall is warped by means. An apparatus for in the North American Patent No. 4,947,667.

The method may further comprising the step of applying a force radially exterior to the wall -lateral of the body of the container to deform at least the second portion of the side wall, radially outward from the initial cylindrical configuration. This step can be done at the same time that the first portion is deformed, or it can be done subsequent to the formation of the first portion in a progressive reconfiguration operation. In another aspect of the present invention, there is disclosed a method for reconfiguring a tubular member, such as a cylindrical, seamless, drawn container of a three-piece container. The method comprises the steps of, providing a tubular element having a first end and a second opposite end, the tubular element having an initial cylindrical configuration. The method further includes applying a force radially outwardly to the tubular member to give at least a first portion of the tubular member radially outwardly from the initial cylindrical configuration p and apply a force radially inwardly to the first portion of the tubular member. tubular element to deform further between the first portion of the tubular element. A reconfigured container of the present invention is also disclosed. The reconfigured container comprises a seamless container body formed from a single metal disc. The metal disk is preferably an aluminum alloy. The container body includes a bottom wall portion at a first end of the container body having a first average diameter, and a cold treated side portion extending from the portion of the bottom wall to a neck portion at a second end of the body of the container. The neck portion is used to attach one end of the container to the body of the container. The side wall includes a first portion having a second average diameter and a second portion having a third average diameter larger than both the first average diameter and the second diameter "The neck portion may comprise a generally cone portion. truncated, reducer diameter and an externally directed flange. The side wall of the. reconfigured container may include a third portion having a fourth average diameter smaller than the third-average diameter wherein the second portion is axially disposed between the first
^ r portion and the third portion. Said side wall may further include a fourth portion having a fifth average diameter larger than the first average diameter and larger than the second average diameter and larger than the fourth average diameter wherein the third portion is axially disposed between the second portion and the fourth portion. The side wall may also include a plurality of radially inwardly deformed segments spaced circumferentially around the second lamination. The segments may extend axially along the second portion of the side wall and have a concave outer arcuate portion. The third average diameter of said second portion 5 of the side wall is approximately 5-7% larger than the second average diameter of the first portion. In an alternative embodiment, a configuration mandrel is provided with a first forming mechanism and a second forming for expanding a portion of the wall
a container. In the broadest sense, the first forming mechanism includes at least two mobile training segments from a first retracted position to an expanded position. When in the expanded position, the first training segments are spaced
circumferentially and form spaces between the first
** training segments. The second forming mechanism - includes a second mobile training segment from a retracted position
. m to an expanded position. The second forming segment is arranged or positioned to be within a space formed between the first forming segments when in an expanded position. In another embodiment having a first forming mechanism and a second forming mechanism, the first forming mechanism includes a plurality of forming segments,
preferably, movable from a retracted position to an expanded position, and the second forming mechanism includes a length of second forming segments, preferably again 5, moving from a retracted position to an expanded position. The first forming segments and the second forming segments are arranged alternately. As the first forming segments move to an expanded position, the segments are spaced circumferentially, whereby gaps are formed between the first consecutive forming segments. The second training segments are configured to move in the WF spaces between the first training segments when they are in the expanded position. Each of the first forming segments and the second forming segments includes a contact surface for coupling with the inner surface of the side wall of the container. The contact surfaces of the first forming segments and the second forming segments can be sized to forming a substantially contiguous surface f when both the first forming segments and the second forming segments are in the expanded position. In this manner, the first and second forming segments can form a smooth expanded portion on the side wall of the container no crease lines. Such fold lines are typically formed when only the first shingle segments are used to expand the portion of the side wall. To effect such a movement, a traction arm having a plurality of cam surfaces can be used to move the plurality of first forming segments from a retracted position to the expanded position, and a plurality of camming surfaces to move the plurality of seconds. forming segments from the retracted position to the expanded position. That is, the axial movement of the actu arm can cam-drive the shifter segments radially outwardly. The cam surfaces may be configured to move the first forming segments radially outward at a greater speed than the second forming segments. In an alternative modality, the actuator arm includes only a plurality of cam surfaces for moving the second forming segments radially outward from the retracted position to the expanded position. In this embodiment, each of the forming segments may include a cam surface to move, in turn, a first? ß forming segment from the retracted position to the expanded position. In a further embodiment of the invention, a method for expanding a seamless container body is provided. The method includes providing a container body that has been stretched and ironed from a single metal disc, to have a side wall extending from a bottom wall at one end, and an opening at an end opposite said wall background. The side wall has an initial 0.ilindric configuration and an initial diameter. The body of the container is placed on a configuration mandrel having a plurality of movable forming segments from a radially outwardly retracted position to an expanded position, each of the forming segments includes a contact surface for coupling an interior surface of the side wall of the container body. A lubricant is pro- tected between the contact surfaces and the interior surface of the side wall. The forcing segments * ^ f move from the retracted position to the expanded position to drive the contact surfaces in engagement with the inner surface of the side wall and expand a portion of the radial side wall towards the outside beyond the initial diameter »In this method, the lubricant helps to reduce the coefficient of friction between the contact surfaces of the forming segments and the inner surface of the side wall. This allows the container to be expanded radially outward to a greater extent than by forming with a higher coefficient of friction. This is because the segments of the side wall that meet the contact surfaces of the forming segments do not close against the contact surfaces (as could happen with higher coefficients of friction) and are liable to stretch together with the material in the spaces between the training segments. If the coefficient of friction is too high, then the entire stretch occurs to the material of the side wall in the spaces between the formation segments. The coefficient should be less than about 0.1, and is preferably on the scale of 0.02 to 0.075. It has been found that a coefficient of 0.05 produces good results. By using a suitable coefficient of friction, it is possible to expand a portion of the side wall to a diameter that is 4% to 5% larger than the initial diameter of the body of the container without a large number of faults é (eg broken containers). Container bodies used for food and beverages are typically provided with a protective coating that is applied to the interior surface of the body of the container. This is preferably done by an airless spray process. The lubricant can then be applied externally on the protective coating and then washed after the expansion operation. Alternatively, the protective coating may include an internal lubricant component such as a carnauba wax. Then the internal lubricant can brighten the surface and affect the. suitable coefficient of friction »Additional aspects of the invention are described in the detailed description or shown in the figures.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES
While this invention is susceptible to embodiments in many different ways, the preferred embodiments of the invention will be described in detail with the understanding that the
-, this description should be considered as an example. ication
It is clear from the principles of the invention and is not intended to limit the broad aspect of the invention to the illustrated embodiments With reference to Figure 1, an apparatus 10 is described in cross section to reconfigure a container body 12. »The body of the container 1.2, is formed from a simple metal disc, preferably a
Aluminum alloy such as an H19 aluminum tempering, and it is stretched and ironed in a conventional manner. The thickness of the metallic disc is approximately 0.0248-0.0289 centimeters, and during the stretching and ironing process the thickness of the lateral wall is reduced to approximately one third of the starting thickness (ie, approximately 0.01016 centimeters). ). The body of the container 12 includes a bottom wall 14 at one end and a seamless side wall 16 extending from the bottom wall 14 »The side wall 16 extends towards a throat portion 18 which is proximate to an open end of the body o -i
The container 12. For the body of the container 12 described in Figure 1, the throat portion 18 includes a frusto-conical portion 20 of reduction diameter and an outwardly directed flange 22. The flange 22 is used to sew twice one end of the container. container to the body of the container 12 in a conventional manner. Unlike a three-part container body having two open ends and a welded side seam, the bottom wall 14 of the container body 12 minimizes the movement of the metal in the side wall during the expansion operation. Prior to the reconfiguration operation of the present invention, the side wall 16 of the container body 12 has an initial cylindrical shape having an axis length and a constant radius of curvature, measured on the longitudinal axis of the container, over the axial length »
After the reconfiguration operation, at least one portion of the side wall is expanded radially outward from its initial cylindrical shape. The reconfiguration apparatus 10 includes a mandrel
24 extending from a housing 26. The housing 26 is secured to a main frame 28 that can be immobile, or part of a rotating turret assembly having a plurality of configurations and mandrels. turret, the main frame can have ten reconfiguration stations. Said assemblies can reconcile 600 containers per minute. reconfiguration mandrel 24 includes a plurality of forming segments 30 spaced near an actuating arm or extension arm 32 »Each forming segment 30 includes a radially outwardly facing surface 34 for contacting or engaging the inner surface 36 of the side wall 16 of the container 12. The bushing segments 30 are preferably a hardened steel, and are preferably filled with a material to increase the wearing capacity of the contact surface 34 of the 30th segment and > It will reduce friction between the forming segment 30 and the internal surface 36 of the side wall 16 of the body of the container 12. The coating material may be, for example, chromium or titanium nitride, although other materials may also be used. In the initial test apparatus used to reconfigure a stretched and ironed seamless container, the forming segments are coated with chromium. Unlike the forming segments used in the past to reconfigure the cylindrical portion of a three-piece container, the segments 30 of the apparatus 10 have been modified to allow expansion of the side wall of a stretched and ironed seamless container body. Specifically, the contact surfaces 34 of the segments formed is polished to an "ex-smoothly" surface finish. In the past, the surface finish, or roughness, of the contact surface was to reconfigure the seamless container. Thin-walled stretched and pressed aluminum alloy, a surface finish of less than about 0.1 millimeter is required, and more preferably about 0.3 millimeter or less. When a coating is applied to the contact surface 34 of the forming segment 30, the contact surface 34 is first polished in a surface finish of approximately 0.3 microns. The coating is then applied and the contact surface 34 is polished rW once more to provide a smoother contact surface 34, the corners 38 on each side of the contact surface 24 have also been modified to allow expansion of the bodies of the body. seamless container stretched and ironed. In the prior art forming segment, the contact surface terminated on each side at a relatively sharp corner having a radius in the order of about 0.5 centimeters. Said corners, together with the rougher contact surface, would tend to tear the treated, fragile hardened aluminum from the body of the container 12. As shown in the cross section of FIGS. 7 and 8, the spokes R2 of the corners 38 of FIG. the forming segments 30 have been significantly increased to approximately 2-3 millimeters, which is approximately twenty times greater than the wall thickness of the side wall 16 of the container body 12. Referring once again to Figure 1, the body of the container 12 is placed on the "configuration 24" mandrel so that the flange 22 bears against a support ring 44 connected to the housing 26. Referring only to the right side of figure 1, the forming segment 30 is shown in a collapsed or retracted position wherein the contact surface 34 is radially spaced inward from the inner surface 35 of the lateral pair-ed 16. The segment formed r 30 includes an edge 46 at one end which is secured in a channel 48 in the The edge 46 is connected to a pin 64 which is placed in a spring 56. The forming segment 30 also includes a first surface of cams 50 and a second surface of cams 52 resting against the first and second cam surfaces 54, 56 of the actuator arm 32. The plastic slide pads 58, 60 are connected to the first and second cam surfaces 50, 52 of the forming segment 30. The first and second -. cam surfaces 50, 52 of the forming segment 30, and the first and second cam surfaces 54, 56 of the actuator arm-are at an angle with respect to the longitudinal axis 62 of the container body 12. In operation, as shown in FIG. the left side of figure 1, the actuator arm-32 has been moved axially away from the bottom part 14 of the container body 12. This axial movement causes the cam surfaces 54, 56 of the actuator arm 32 to cooperate ^^on the cam surfaces 50, 52 of the forming segment 30"to move the forming segment 30 radiantly outward towards the inner surface 36 of the side wall 16» The contact surface 34 of the forming segment 30 contacts or engages the surface inner 36 of the side wall 16 of the container body 12, and expands a portion 68 of the side wall 16 radially outward of the longitudinal axis of the container beyond the initial cylinder of the container body 12 »^ ß During the expansion operation, the pin 54 is also moved radially outwardly and compresses the spring 66. When the expansion of the portion 68 of the side wall 15 is completed, the actuator arm 32 is moved axially towards the bottom wall 14 of the body of the container 12 and the spring 66 forces the pin 64 and the forcing segment 30 back into a collapsed or retracted position.The body of the container 12 can then be removed from the mandrel.
^ configuration 24. As shown in FIG. 1, a lower portion 70 of the lateral web 16 does not contact the bushing segments 30 and maintains the average principal diameter of the initial cylindrical shape of the side wall 16. However, the expanded portion 68 after the operation has a major average diameter, which is larger than the average principal diameter of the lower portion 70. As you can see on the left side of the figure, the flange 22 of the body of the container-12, is thrown out
* of the ring 44 during the reconfiguration operation »The body of the container 12 of figure 1 is shown after the reconfiguration operation in figures 10-13. Referring to figure 2, another container reconfiguration apparatus Modified 72 is described. Figure 2 describes elements for applying an axial load force to the body of the container 12 during the operation of
# ^^; reconfiguration, and to remove the body of the container 12 from the configuration mandrel 24 (not shown in figure 2) after the operation. The apparatus 72 includes a body support structure of the container 74 for applying an axial loading force to the body of the container 12. The structure includes a housing 76 connected to the bottom platform support 78.
The platform support 78 is axially aligned with the
^ 24 configuration mandrel and leans on the background wall l? of the body of the container 12. The platform support 78 is connected to an arrow 80 in the housing 76. The arrow in turn is connected to a follower support bracket of the follower roller of the cam 32 that includes a follower roller of the cam 34. The follower roller of the cam 84 follows a cam (not shown) that performs axial movement of the platform support 78 during the reconfiguration operation. Accordingly, it is m | > Referring or the complete apparatus 72 is part of a turret assembly. The follower support bracket of the cam 82 is guided by a plurality of pins 86 which are surrounded by springs 88. According to the forming segments 30 of the configuration mandrel 24 are moved radially outwards to engage the internal surface 36 of the wall 16 to 16, the follower roller of the cam is axially driven towards the bottom wall 14 of the body of the cam follower support bracket of the cam 84 moves axially towards the bottom wall .14 of the container body 12 which compresses the springs 88 and the arrow 80 moves with the follower support bracket of the cam follower 82 compresses the springs 90 placed in the cavity 91 immediately in the back of the platform stand
78. These springs 90 are preset to the external load ß required. In this way, the platform support 78 applies an external force or load spring-loaded axially to the bottom wall 14 of the container body 12. The external load applied to the bottom wall 14 maintains the flange 22 of the body of the container. container 12 pressed against the ring 44 in the housing 26 containing the configuration mandrel 24. The external load during the reconfiguration operation is believed to aid in the expansion of the side wall 16. When the reconfiguration operation is completed, the cam is released and the springs 88 force the follower roller of the cam 82, and the platform support 78, in a direction axially away from the body of the container 12. Additionally, the support structure 74 includes a hollow tube 92 extending from the platform support
78 to perform a vacuum pressure between the platform support 78 and the bottom wall 14 of the container body
12. The tube 92 is connected to a hose 94 which is connected to a pump (not shown). The vacuum pressure ^ P helps in maintaining contact between the platform support 78 and the bottom wall 14 of the container body 12. A plurality of O-rings 96 are placed around the tube 92. The platform support 78 can be used to load and discharging the container body 12 from the configuration mandrel 24. Vacuum pressure is particularly useful for holding the body of the container 12 to the platform support during loading and unloading. ^ P Figure 2 also describes a removal sleeve
98 to move the body of the container 12 axially away from the configuration mandrel 24 after the reconfiguration operation. A top view of the removal sleeve 98 is described in Figure 3. The removal sleeve 98 includes a main body 100 mounted near two guide rods or poles 1.02. A first and a second jaw or fastener element 104, 106 are pivotally mounted to the main body 100 by pivots | L08, 110. The jaws are designed to engage the throat portion 18 of the body of the container 12 and aid in the removal of the body. container body 12 of the configuration mandrel 24. In an alternative embodiment described in the figures
4 and 5, a reconfiguration apparatus 112 is described with an external tool 114 for providing radially inward pressure to the expanded portions of the side wall 16.
# External tool is used to create radially deformed segments inward in the expanded portions of the side wall 16. Figure 9 describes the internal mandrel of the apparatus of Figure 4 with the outer ring and platform support removed for clarity. The external tool 114 includes a plurality of external forming segments 116 made from hardened steel. Each forming segment 116 includes an external contact surface for contacting or coupling a
^ external surface 1.18 of the side wall 16 of the body of the container 12. The external forming segments 116 are aligned to make contact with portions of the side wall
16 of the container body 12 that are in the gaps between the bushing segments 30 and the. configuration mandrel 24 »The external tool 114 includes an actuator arm 120 having a cam surface 122 cooperating with a cam surface 124 in the external forming segment 1.16. The movement on the direction of the longitudinal axis of the body of the container 12 causes the actuator arm 120 to raise the external forger-segment 116 radially inward. The actuator arm abuts and compresses a spring 1.26 partially supported in a channel 128 in an upper portion 130 of the actuator arm. After the external forming operation, the spring forces the actuator arm 120 back to its initial position. The external forming segments 116 are of the segments .136 »As the actuator arm-120 is moved to its initial position after the operation, the springs 136 force the forming segments 116 back to their initial positions. Alternatively, the external forming segments 116 can be fixed in place, ie immobile, with respect to the side wall 16 of the container body 12.
According to the forming segments 30 of the mandrel? With Figure 24 moving radially towards the outside, the portions of the side wall 16 are radiated outwardly in contact with the outer forming segments.
.116 allowing simultaneous radially inward deformation of the side wall 16. As described in Fig. 5, the actuator arm 120 is in the shape of a ring having the cross-sectional shape shown in Fig. 4. In FIG. embodiment described in Figures 4, 5 and 9, the forming pieces 30 of the configuration mandrel 24 include a modified contact surface 137. The contact surface 136 includes a first portion in an outwardly convex arc 140 axially spaced from the first portion. in arc .1.38, and a third portion in an outwardly convex arc 142. These portions 138, 140 and 142 form corresponding expanded portions in the side wall. 16 of the body of the container as described in Figures 17- ^ 19, and in Figures 14-16 without the deformed segments internally. It is evident that a large variety of shapes can be formed by modifying the contact surface of the 30 or 1.16 forming segments. A perspective view of the configuration mandrel without the outer ring in place is shown in Figures 27 and 28. The figure 27 shows the forming segments 30 is a retracted position. Figure 28 describes the forming segments 30 in an expanded position. Fig. 29 shows a perspective view container positioned on the configuration mandrel with an external forming tool 114 surrounding the container. In an alternative mode, the actuator arm-24 and the forming segments 30 of the configuration mandrel 24 can be configured so as to progressively allow reconfiguration of the side wall 16 of the container body 12. That is, the actuator arm 24 and the forming segments 30 can be modified to include an impermanence time in the cam surfaces to allow, for example, expansion of the first convex surface at arc 138 before beginning expansion of the second and third convex surfaces at arc 140, 142. This may decrease the tension total in the side wall 16 when configuring more complex shapes. In another alternative embodiment, an expansion apparatus 144 is described in Figure 5. The apparatus 144 includes a generally annular flexible mandrel 146, formed from a material, elastic such as rubber or polyurethane, which is placed in a body of the container 12. Container body .1.2 includes a side wall 16 having an initial cylindrical shape. In this embodiment, the body of the container 12 does not include a reduction diameter portion in the throat portion 18 of the body of the container 12. This is necessary to allow insertion and removal of the mandrel 146 from the container body 12 before and after the expansion operation. The mandrel 146 includes a generally hollow cylindrical channel or hole .1.48 having a circular cross-section centrally located in the mandrel 146. The mandrel 146 also includes an external configuration surface 147 for contacting the inner surface 36 of the side wall 16. The outer configuration surface .147 includes an outer annular recess channel 150 having a diameter that is smaller than the diameter of the remaining portions of the external configuration surface 147 of the mandrel 146. plunger or expansion die 152 is forced through the centrally located channel 148 axially towards the bottom wall 14 of the container body 12. The plunger 152 includes a head portion 1.54 having a diameter greater than the diameter of the channel 148. Since the plunger head 1.54 has a diameter greater than the centrally located channel 148, as the plunger head 154 moves axially towards the bottom wall 14, the outer clamping surface 147 of the mandrel 146 is moved radially outwardly in contact with the inner surface 36 of the side wall 16 and expands the side wall 16 radiantly outwardly. As the head of the plunger 154 moves to a position axially aligned with the annular recess channel 150, the corresponding portion of the side wall 16 is not expanded radially outward, or depending on the depth of the annular channel 150, is radially expanded ß outward to a lesser extent than other portions of the side wall 16. In this manner, a barrel shape similar to the configuration mandrel 24 of Figure 4 may be affected. Because the radially outward deformation or expansion of the portions of the side wall 16 results from the downward movement (ie, axially toward the bottom wall 14 of the container body 12) of the head of the. plunger 154, the expansion of the portions of the side wall 16 is carried out gradually instead of all at the same time. It's 33
Accordingly, a portion of the side wall 16 proximate the throat portion 18 is expanded prior to a portion of the side wall proximate the bottom wall 14. As the head of the plunger 154 passes through any portion of the channel . 148, the mandril summarizes its original shape due to the elastic nature of the material. During the expansion operation using a configuration mandrel 24 with a plurality of forming segments 30, the segments 39 separate as they move radially outward and are separated from each other as they make contact with the inner surface. 35 of the side wall 16. The side wall 16 in this manner is first stretched in the cavities between the contact surfaces 34 of the driver segments 30 during the expansion operation (However, as explained below, the lubrication itself between the contact surfaces of the forming segments and the inner surface of the container to obtain an adequate ß coefficient of friction can help by allowing the material of the side wall to rest on the contact surfaces also to stretch) »This also tends to form channel lines 150 in the expanded portions of the side wall 15 as described in FIG. 10. Channel lines are not necessarily obtained using the elastic mandrel 146 of Figure 5 (As explained below, a modified configuration mandrel can be used to decrease or eliminate channel lines).
The outer configuration surface 147 of the mandrel 146 may have a variety of contours or shapes.
* This will produce a corresponding variety of shapes in the side wall 16 of the body of the container 12. As it was described in Figures 10-12, the body of the resulting container 12 can have a variety of shapes.
In all cases, however, the wall 16 to the container body 12 includes at least a portion that has been
_ ^ expanded radially outward beyond the form
~ ^ Initial cylindrical container body, and includes a major average diameter greater than the primary pr-average diameter of the initial cylindrical shape. Additionally, said portions also have a principal average diameter that is larger than the average principal diameter of the portion
of par-ed bottom 14 of container body 12. For container bodies that include annular outward flange in bottom wall portion 14, the outer portion of the container
- JÉ *. The tab is considered in calculating the main average diameter of the bottom wall portion 14. With reference to Figure 10, the container body 12 includes a bottom wall portion 14 having a first major average diameter. The side wall 16 of the container body 12 includes a first portion 164 having a second average principal diameter
approximately equal to the main average diameter 162 of the bottom wall portion 14 and equal to the average diameter, principal of the initial cylindrical shape of the container body. The side wall also includes a second portion 166 which has been expanded radially outwardly. The second portion 166 has a third major average diameter 5 168 which is larger than the main average diameter of the first portion 164 and the average principal diameter 162 of the bottom wall 14. The channel lines 1.60 are visible in the second portion 166 of the forming segments 30 of the internal mandrel 24. The material of the side wall is mainly stretched in the cavities between the forming segments during the reconfiguration operation. A body of the alternative container is described in Figures 14-16. This container body 12 includes a bottom wall 14 having a first average diameter
main 170. The side wall .1.6 includes a first portion
172 having a second principal average diameter approximately equal to the principal average diameter 170 of the f bottom wall portion 14 and equal to the principal average diameter of the initial cylindrical shape of the body of the
container. The side wall 16 also includes a second portion 174 having a third major average diameter 176 greater than the average principal diameter of the first portion 172 and the average principal diameter 170 of the bottom wall portion 14 »The side wall further includes a third portion 1.78 having a fourth major average diameter approximately equal to the major average diameter of the first portion 172. The side wall further includes a fourth portion 180 having a fifth major average diameter 182 approximately equal to the third major average diameter 176 The side wall further includes a fifth portion 1.84 having an average principal diameter approximately equal to the principal average diameter of the first portion, and a sixth portion 186 having a principal average diameter approximately equal to the third major average diameter. side wall includes a seventh portion 1 .88 ^ having a principal average diameter approximately equal to the principal average diameter of the first portion 172. Figures 17-1.9 describe another embodiment of a container body 12 having a side wall 15 with first, second and third portions expanded 190 , 1.92, 194 »The side wall also includes a plurality of inwardly deformed segments 196 circumferentially spaced near the side wall 16.? F Figures 20-22 describe another embodiment of a container body 12 having a side wall 16 with first and second expanded portions 198, 200. The configuration mandrel used to form this container body was configured so that the forming segments were separated at a more than normal distance by contacting the side wall 16. Light wrinkles 202 can occur in the cavities between the forming segments. As shown in cross section in the figures mandrel of alternative configuration 300 can be used with the reconfiguration apparatus of the present invention to reconfigure a body of the container. The configuration mandrel 300 includes a first forming mechanism in the form of a plurality of first forming segments 302 that are spaced near an actuator arm 304. The configuration mandrel 302 also includes a second forming mechanism-in the form of a plurality of second forrring segments 306 that are alternately spaced near ^ from the actuator arm 304 between the first forming segments 302. The first forming segments 302 are movable from a collapsed or retracted position (as shown in FIG. 24), generally having a diameter that is smaller than the diameter of the body of the container to be expanded and smaller than the diameter of the open end of the container body that can be constricted, to an expanded position that generally has a diameter that is greater than the initial diameter of the wall later-to the body of the container (as shown in figure 23). Similarly, the second forming segments are also movable from a retracted position to an expanded position. Each of the first forming segments 302 includes a contact surface 308 for coupling the inner surface of the body of the container. Each of the second forming segments 306 also includes a surface, t-fcC contact 310 for coupling the inner surface of the body of the container. As shown in Fig. 24, the second forming segments 306 are nested between the first forming segments 302. However, as shown in Fig. 23, when both first and second forming segments 302, 306 are moved to the expanded position, the combined contact surfaces 308, 310 are dimensioned to provide a substantially continuous surface circumferentially around the expanded portion of the l? side wall. This configuration helps to eliminate or avoid channel lines to be formed at the edges 312, 3.1.4 of the first forming segments 302. The driving arm 304 includes a plurality of cam surfaces 316 for raising or moving the plurality
first forrring segments 302 radially outward, and a plurality of cam surfaces 318 for moving the plurality of second forming segments 306 radially ß outwardly. The cam surfaces 316, 318 are configured to allow the first forming segments
moves radially outwardly before the second forming segments 306. This can be done simply by adjusting the inclinations of the cam surfaces 316, 318. In the operation, the actuating arm 304 is moved axially to raise the first forming segments 302
r dial out from the retracted position to the expanded position. The actuator arm also moves the second forming segments 306 radially outward from the retracted position to the expanded position. The second forming segments 306 are positioned to move in the cavities between the first forming segments 302 as they expand. Figures 25-26 describe a slightly modified embodiment of a configuration mandrel 320 having a first forming mechanism and a second forming mechanism. In this embodiment, the second forming mechanism includes a plurality of second forming segments 322 in FIG. where each second forming segment 322 includes an integral lifting surface 324 »The integral cam surfaces 324 of the second forming segments 322 are used to radially lift out a plurality of first forming segments 326 of the first forming mechanism from a retracted position to a position expanded. The actuator arm includes a plurality of ißf cam surfaces for lifting or moving the plurality of second forming segments 322 radially outward from a retracted position to an expanded position. As the second forming segments 322 are moved radially outward, the cam surfaces 324 of the second forming segments 322, in turn move the first forming segments 326 radially outwardly. In both modalities, the contact surfaces of the first and second forming segments can be polished on a surface of 0.3 μm. Through initial testing, it is believed that friction between the contact surfaces of the forming segments and the inner surface of the side wall of the container body plays an important role in achieving optimal radially outward expansion. In the expansion operations described above with respect to the apparatuses described in FIGS. 1, 4 and 9, the configuration mandrel includes a plurality of forming segments that are raised radially outwards to engage the inner surface. of the side wall. As the forming segments move radially outward they separate circumferentially and leave cavities between consecutive driving segments. If the coefficient of friction between the contact surfaces of the forming segments and the segments of the inner surface of the side wall resting on the contact surfaces is very high, then the material in said side wall segments will effectively secure against the contact surfaces during the expansion operation. That is to say, all stretching will be achieved by the material of the side wall in the cavities between the forming segments. This limits the amount to which the sidewall can be expanded »
By providing a lubricant between the contact surfaces of the forger segments and the inner surface of the side wall, the coefficient of friction can be lowered to allow the material of the side wall -Ü to lean on the contact surfaces to circumferentially stretch, thus How to reduce it slightly axially, during the expansion operation. This decreases the tension in the material in the cavities, and allows greater expansion of the side wall. Indeed, the lower coefficient of friction is believed to allow the material to lean on the contact surfaces to slide against said surfaces. The inner surface of the container body is T typically provided with an inner liner to protect the product when it is filled. The lubricant can be applied externally or sprayed onto the protective coating before the expansion or reconfiguration operation. This lubricant can then be washed, or not if it does not damage the product, left in it. container body »Alternatively, the lubricant can be incorporated as an internal component of the protective coating. In this way, the following coatings with internal lubricants provide good expansion properties also meet the product protection requirements: CR023-142 from Dexte --Midland (including 0.5% carnauba wax); CR023-144 from Dextei-Midland (which includes 1.5% carnauba wax); and 640-C-696 (ICI) from Glidden (which includes 0.5% carnauba wax). CR023-144 from Dextet-idland allows the container to be stretched more than the other two liners. However, Dexter-Midland's CR023-142 and Glidden coatings show less de-indentification during the application of a re-sprayer, which can be an important yes factor. The re-coating of the coating is determined to be necessary in the commercial production of expanded containers. In addition to the three coatings discussed, the initial test has been made with coatings that have 5% or 1.5% (by weight) of a modified Teflon polyethylene wax as the internal lubricant. The coating with the .1.5% lubricant allows for even more stretching than the - CR023-144 from Dextei-Midland. However, this coating has not been tested to meet product protection requirements. It has been found that a coefficient of friction between the contact surfaces of the forming segments and the interior surface of the side wall must be less than about 0.1. , and preferably on the scale of 0-02 - 0.075. A coefficient of 0.05 has been found to give good results. Figures 30-33 describe another embodiment of a seamless container body 330 formed in accordance with the present invention. Container body 330 includes a plurality of expanded portions 332, 334, 336 and a plurality of inwardly deformed portions 338. The container described in Figures 30-33 is preferably formed from a stretched and ironed container body that has a sidewall diameter of Jfcentre 6.2915 cm at 6.3068 cm and a height of approximately 13.1318 measured from the support base to an eyelet facing outward at the open end. The container body includes a frusto-conical narrowed portion. The side wall of the container body prior to the expansion operation has a material thickness of about 0.0124 crn to 0.0132 crn, and includes metal-thickness transition zones that increases between the side wall and the 340, 342 joints between the narrowed portion at one end and the portion of the ^ T bottom at the opposite end, respectively. These transitions can extend up to 1.27 cm in the area of the side wall. As shown in Figures 30 and 31, the expanded portions 336, 332 extend into the transition zones of the side wall. The diameter of the expanded portions 332, 334, 336 is preferably 6604 crn which is an increase in diameter of about 5%. While the specific modalities have been illustrated and described, numerous modifications come to mind without sharply departing from the spirit of invention.
