Definitions

  • This invention relates to container ends according to the preamble of claim 1 and a method of manufacturing them according to claim 9.
  • Such a reclosable feature has become available in plastic (non-metallic) containers (ordinarily blow-molded) for carbonated beverages, in both two liter and smaller one-half liter (0.59 ml) sizes.
  • plastic containers ordinarily blow-molded
  • Such containers have a frangible sealed and resealable screw-on cap molded of a suitable plastic, but loss of carbonation through the plastic body materials, resulting in lower shelf life of the product and difficulty in recycling same has impaired widespread acceptance of such plastic containers.
  • containers for fluids, and particularly liquids under pressure e.g. the beer/beverage containers
  • the reclosable feature can be constructed of metal, preferably aluminum.
  • the container includes a top with an integrally formed neck portion terminating in an inwardly rolled portion surrounding a container opening.
  • the neck portion has integrally formed slanting camming surfaces extending outwardly therefrom which are engageable by complementarily shaped camming surfaces which project inwardly from a rim part of a cap having a seal member positioned in a groove at a junction between the rim and a top part of the cap. Engagement of the complementary camming surfaces draws the seal member downwardly onto an upper surface of the inwardly rolled portion of the neck portion.
  • the principal object of this invention is to provide a resealable end including a removable cap construction (also called a neck and hat herein) which can be added, such as by a conventional seam, to a metal container body to obtain resealing containment of partial contents retained in the container, even under pressure, and to provide an improved mouth construction (or pour opening) for better pouring and for comfortable direct drinking from the container; and to provide an improved method of making such a resealable hat and neck.
  • a removable cap construction also called a neck and hat herein
  • the present invention provides a resealable container end for a liquid holding container as claimed in claim 1 and a method of manufacturing such a container end as defined in claim 9.
  • the container is provided with a reclosable metal type of cap or hat.
  • the end, with an attached sealed hat is attached to the open end of a filled can by a conventional double rolled seam connection.
  • the container end is preferably coupled to a can body by conventional double rolled seam attachment between the bottom of the neck and the rim of the can body.
  • the container end of the present invention is comprised of two major parts, a dome structure 10 and a cap or hat member 12 which is in the general form of an inverted cup, including an outwardly curled rim 13 depending from the top panel 14 of hat member 12.
  • a pair of containers including can type bodies 15 each provided with this end, such bodies having a concave central portion 16 in their bottoms are shown stacked one upon the other to demonstrate the ability of the container to be so stacked while including the novel resealable end.
  • Such bottom configuration of can bodies is per se known.
  • the dome includes a neck structure 11 with a wing-like lower rim 20 capable of being seamed to the upper end or rim of a can body (see the left edge of Fig. 2), and optionally including a sealing compound 21 on the underside of rim 20.
  • Rim 20 extends outward from the lower edge of a generally frusto-conical central neck section 22 which has formed on its upper edge a generally cylindrical upper neck section 25 which terminates at its upper edge in a outward curled seal rim 30 formed upon a ledge 31.
  • seal rim 30 there is shown an elastomeric preferably circular seal 32, which may take different forms as later explained, but in general is fitted within cap 12.
  • These lugs 35 cooperate with a second set of inwardly extending lug members 36 formed in the curled rim 13 of hat member 12 to hold the cap firmly on the dome structure, as later explained.
  • the cooperating first and second lug members 35, 36 draw top panel 14 against the curled seal rim 30, and compress seal 32 against the curled rim 30 and ledge 31, as in Fig. 2.
  • Seal 32 can take different forms.
  • the annular O-ring type seal is molded as a peripheral part of a thin flexible and compliant disk 33 which is attached to the underside of top panel 14.
  • the O-ring type seal is made as a rim of a circular thin member which is applied to the outer portion of the underside of top panel 14.
  • the compressible elastomeric seal member is positioned within the hat member 12, as shown in Fig. 2. This arrangement will retain initial pressurization of product (if necessary), and hold residual pressure after reclosing.
  • a typical press includes an upper die plate UP, a lower die plate LP, and guide posts GP which maintain the alignment of a punch or punches on upper plate UP and a corresponding die or dies on lower plate LP.
  • guide posts GP which maintain the alignment of a punch or punches on upper plate UP and a corresponding die or dies on lower plate LP.
  • Figs. 3A--B and 4A--B show the hat or cap and the two steps of forming the completed lugged hat 12. Both steps may be contained in the same press, as this is convenient in a high production environment, however the second operation can be performed in an auxiliary piece of equipment.
  • a blank is cut from either sheet or coiled material on the down stroke of the press by blank punch 45.
  • the blank is drawn into a cup shaped hat part 40-1.
  • the panel shape is formed into the top of the hat part 40-1 by the punch 45 and cooperating die 46 (Fig. 3A).
  • the lower curl ring 48 which is under spring pressure, raises with the blank punch.
  • the edge 50 of the hat part 40-1 is curled outward into the cavity formed by curl ring 48 and blank punch 45, thus completing a formed hat or cap part 40-1 with an outside curl 55, as shown in Fig. 4A.
  • a punch 60 and die 62 having a cavity which receives the hat part 40-1 in an inverted orientation, resting in a cavity 63 in die 62.
  • a punch probe comprising a plurality (e.g. three or four) of radially movable fingers 64 cooperating with a central tapered actuating cam 65, is inserted first into the product side (interior) of the formed hat part 40-1 before the punch closes against the hat part 40-1.
  • the fingers 64 are extended by cam 65 (to the position shown in Fig.
  • a curling ring 67 on the punch has a set of cavities in its radially inward section, these corresponding to the location and size of the lugs 36.
  • the radially outward region of ring 67 has corresponding inward extending surfaces 68 which move material from the outside curl 55 toward the inside of the hat part 40-1, as the curling ring 67 bottoms out over finger ends 66. This will establish the final form of hat part 40-2, including inwardly directed lugs 36 (preferably three or four) above the outward curled edge 50.
  • the neck/dome structure 11 is formed in seven operations as described hereafter. However the first station Blank & Draw operation and the second station Redraw operation can if desired, be combined into a single station, reducing the total number of stations to six. The following description will assume that the first and second stations are separate.
  • a blank is cut from either sheet or coiled material, and is drawn into a cup shaped part 70-1, as shown in Figs. 5A & 6A.
  • the part 70-1 is redrawn to form the countersink area 72 and the edge 74 is curled to establish the final outside diameter.
  • This allows the resultant part 70-2 to be placed into a belt type transfer system from this operation onward, enabling higher production speeds than can be achieved with other forms of transfer systems.
  • the first and second stations can remain separate, however in a production atmosphere that would incorporate an automated transfer system, it may be preferred that stations I-N & II-N be combined to allow immediate placement of the parts into a belt, or other similar transfer system.
  • part 70-2 is redrawn to obtain additional height of the central section 75, and in the fourth station IV-N a ledge 76 is formed, upon which the curl (formed in the seventh operation, as later described) will rest, resulting in part 70-3 (Figs. 5D & 6D).
  • a hole or opening 78 is pierced through the part, and in the sixth station VI-N opening 78 is extruded upward to obtain the material necessary for the curl on part 70-4 (see Figs 5F and 6F).
  • the curled seal rim 30 around the drinking opening is formed.
  • the curl is formed through 360 degrees so the raw edge of the material cannot come in contact with the user's mouth when drinking directly from the container. This results in the part 70-5 (shown in Fig. 6G).
  • the lugs 35 can be added to the upper neck section 25 in a further press station. It is also possible to form such lugs in separate auxiliary equipment which employs the technique of rolling threads or the like in thin-walled metal cylindrical or cup shaped parts.
  • the part 70-5 is placed in a die member 80 which includes cavities 81 corresponding to the desired external configuration and location of the lugs 35. In a preferred embodiment there will be three or four such cavities (as before), which will be aligned around the upper neck section at the desired location of the lugs 35.
  • Fingers 84 have embossing parts 86 configured to the size and shape of lugs 35 and are adapted to mate with cavities 81.
  • the fingers 84 are retracted, the punch 82 and die 80 separate, and the completed neck part 70-5 is removed.
  • the wing-like lower rim can be reshaped, as by further curling, preparatory for the seaming operation when the end is attached to a filled can body.
  • the wing-like lower rim or seaming curl will be finish shaped, and lugs 35 will be formed at the same time, using rotary techniques.
  • the part 70-5 is grasped in a rotating chuck 90 and rotated about a first axis 92 which coincides with the centerline of the upper neck section 25.
  • Cooperating rotatable rolling (or ironing) tools namely an outer anvil 94 rotating on an axis 95, and an inner die 96 rotating on an axis 97, are brought into contact with the wall of the neck section.
  • the anvil and it's cooperating die, and their respective rotary drives, are movable toward and away from the chuck/part axis 92 in a radial direction and in a longitudinal direction; thus these parts can be moved into and out of, and toward and away from the surfaces of, the upper neck section 25 of the chucked part 70-5.
  • These rotary anvil 94 and die 96 tools have the male/female configurations of the lugs 35 formed thereon. When the anvil and die are engaged and rotated with the rotating part 70-5, the lug configurations are pressed into the wall of the upper neck section.
  • the present invention provides methods for making the neck and hat member container end.
  • Fig. 8 illustrates geometry of the hat of cap at 6.21 bar (90 PSI), in comparison with approximate undeformed geometry, the deformation being due to application of external vertical axial load on the container due to direct stacking of a second container or can on top of another can (as in Fig. 1).
  • Testing and computer modeling indicates the hat or cap will tend to lower to minimum position with doming still present in the hat.
  • the seal 32 will tend to push further into the gap between hat member 12 and the external surfaces of the pouring opening, causing a tightening of the seal.
  • Fig. 9 shows deformed geometry of hat member 12 at 6.21 bar (90 PSI), compared to approximate undeformed geometry of the hat member.
  • the loading is applied to the center of the hat member and the hat member will tend to flatten due to the moment shown.
  • Such deformation may cause some outward movement in the sides of the hat member (shown exaggerated).
  • This could, potentially, decompress the O-ring seal somewhat, but even in such a lesser pressurized state there is built-in interference between the seal member, the upper neck region at dome, and the cap. Therefore, a container fitted with a seal according to this invention will not lose its sealing, although it may experience some lowering of the hat member as seen in the above-described situation (Fig. in combination with flattening of the hat member.
