Definitions

  • This invention relates to containers and more particularly to decoratively shaped containers predominantly used for holding beverages.
  • the bottle shaped container has been a preferred configuration for many years due to its ornamental appeal and the ease with which fluids may be consumed or dispensed.
  • One piece metal bottle containers have been disclosed as well as two piece and three piece containers.
  • two piece metal containers have become the most common.
  • bottle shaped containers found wide consumer appeal when made from other materials such as plastic or glass
  • metal containers in a bottle shape have not found wide acceptance.
  • Some beverages are now packaged in impact extruded one piece containers, but these tend to require a thick side wall and are therefore quite expensive.
  • some beverages are packaged in an aluminum bottle produced by Daiwa Can of Japan. While this container can be attractively decorated, it does not provide a variety of shapes and the seam between the upper portion of the bottle and the bottom is quite visible to the naked eye limiting its aesthetic appeal to the consumer.
  • Other two-piece metal bottle shaped containers for use with beverages and other products have also been produced, however, they also have readily visible seams.
  • a two piece bottle shaped metal container having the seam between the two pieces that is hard to detect is desired for aesthetics and enhanced consumer appeal, easy manufacturing and reduced manufacturing costs.
  • This container could utilize either snap-on, crimped, threaded, or lug closures and different types of seals within these elements.
  • the present invention provides a bottle or other decoratively shaped metal container including a removable closure.
  • the container is formed from an upper portion and a lower portion that are joined together at a seam that is largely hidden from view.
  • the top portion includes a spout and connecting elements that allows the closure to be attached to the top portion that in conjunction with the removable closure closes the container.
  • adhesive material placed on one or both mating peripheral flanges of the upper and lower container portions extrudes between the peripheral flanges.
  • the adhesive coats the surfaces at the peripheral flange sealing or blocking the bare metal at the extremities.
  • the adhesive when applied is applied to the bare metal at the extremities as well as the peripheral flanges.
  • the upper and lower portions are preferably coated with a lacquer, or another type of coating, prior to the application of the adhesive because the current art of forming these pieces preferably requires them to be coated to avoid metal pick up on the tooling and exposure of the bare edge to the contents of the container.
  • the adhesive may be applied to the bare metal. This adhesive sealing process provides the benefit of allowing easy manufacture of a bottle shaped container from metal.
  • the adhesive sealing process of the present invention may eliminate the need for subsequent applications of coating material to the seam either as an overcoat or as a spot repair where the two portions of the container mate.
  • the container includes one or more seals between the top portion and the closure.
  • a seal member is within the closure and forms a seal between a downwardly projecting rim of the closure and a ledge formed in an upper part of the spout.
  • a second seal member is used in addition to or in place of the first seal member.
  • the second seal member is placed against a top panel of the closure and contacts a top surface of a curled seal rim of the spout.
  • This type of seal member advantageously may be used to form a seal with minimal use of downward force. This is especially useful when the container includes thin sidewalls that do not possess superior axial strength.
  • the second seal member is made from a heat softened material which forms a superior seal with the application of heat, thus, reducing the need for excessive axial force. As stated above, reduced axial force requirements are beneficial in a container utilizing thin sidewalls.
  • the hidden seam of the present invention is achieved by one or more of the location of the seam and the design of the surrounding elements of the overall bottle design.
  • the hidden seam can be obtained with either the mating flange of the upper portion of the bottle overlying the mating flange of the lower portion or with the lower portion overlying the upper portion.
  • the bottle is configured to have a relatively long slender neck with the seam between the upper and lower portions of the bottle located at or near the base of the long slender neck.
  • the lower portion of the bottle is necked in a substantial amount and a mating flange along the upper periphery of the lower portion of the bottle is joined to a corresponding mating section located around the lower periphery of the upper portion of the bottle.
  • the mating flange around the base of the long slender neck overlies the mating flange around the top of the base and because of its location is not readily apparent to the casual observer.
  • the lower portion is provided with a step immediately below the mating flange. The step is about the same width as the thickness of the mating flange along the lower periphery of the upper portion.
  • a cone shaped upper portion is attached to a lower body portion along a mating flange that is recessed below a shoulder section of the cone shaped upper portion and then fits inside an overlying mating flange on the bottom portion.
  • the cone shaped top is formed to have shoulder section immediately above the mating flange, when it is assembled with the lower portion of the bottle, the shoulder section tends to hide the edge of the overlying flange that would otherwise be plainly visible at the seam.
  • the shoulder section projects outwardly more than the thickness of the metal in the mating flange around the upper peripheral edge of the lower portion of the container.
  • the shoulder projects outwardly a distance that is at least twice the thickness of said flange and preferably a distance that is three times or more the thickness of said flange.
  • the above-described seams between the upper portion and the lower portion of the metal bottle can be further hidden from view by certain decoration techniques.
  • the seam and adjacent areas of the bottle can be covered with ink, lacquer, other coatings and/or shrink or stretch wrap plastic labels, plastic roll labels and/or paper labels all of which can have geometric or other graphics that tend make it harder for the casual observer to see the seam.
  • the term adjacent may include immediately adjacent surfaces or it may also include surfaces extended substantially beyond the immediate area of the seam out to and including the surface of the entire bottle.
  • the as-formed surface finish of the upper and lower portions of the present two piece bottles can be substantially different.
  • Yet another approach would be to colorize with decoration, coating, lacquer, paint or ink the upper, lower or both portions at a stage in their manufacturing process or the pre-color sheet stock in such a way that the hue, intensity and/or other color attributes vary to compensate for changes in these color attributes that occur during subsequent forming operations so that no color gradient or differences in surface finish is readily apparent to the casual observer.
  • Two other approaches would be to make the different appearance to the two portions part of the final design, or use the color gradient that could result from manufacturing as part of the design.

  • the upper portion may be formed from the same or a different metal or from plastics, but is preferably formed of aluminum by a draw redraw type process.
  • a benefit to aluminum or steel construction is that the cold temperature of a liquid inside the container may be felt by the user and that the shelf life of the product may be extended. Thus, the user may feel more refreshed as he or she is consuming a cold beverage.
  • the container may hold anywhere from about 148 milliliters (5 ounces) to about 1.18 liters (40 ounces) of product.
  • the container of the present invention is a beverage container used advantageously for beer or a carbonated beverage; however other liquid or pourable solid products can be packaged in the present containers.
  • the lower portion 14 or body portion of the containers shown in Figures 1 and 2 has an open top and closed bottom and includes a base 15 and a top peripheral flange 16.
  • the base 15 may have a generally circular profile. Other profiles for the base 15 are possible including asymmetrical and symmetrical non-circular profiles.
  • the base 15 at its center may be deformed inwardly towards the interior of the container. This indentation increases the strength of the base 15 of the body portion 14.
  • the body portion includes sides 17.
  • the sides 17 of the body portion 14 may be contoured to create varying bottle shapes.
  • the body portion 14 includes a peripheral flange 16 at its top that may be vertical but is preferably slightly angled from vertical as shown in Figures 1C and 2C.
  • top peripheral flange 16 forms the outside surface of the seam as shown in Figure 1, then it is preferably angled outwardly. Any angle ⁇ can be used, an angle of less than 45 degrees is advantageous; however an angle of less than 5 degrees is preferred and an angle of 1 - 3 degrees is most preferred. If top peripheral flange 16 forms the inside surface of the seam as shown in Figure 2, then it is preferably angled slightly inwardly. An angle of less than 10 degrees can be used; however, an angle of less than 5 degrees is preferred and an angle of 1 - 3 degrees is most preferred. An angle of 2 degrees is illustrated in Figures 1C and 2C. In the embodiments shown in Figure 2, the lower portion 14 also includes a transition section 18 immediately below the top peripheral flange and a main body section below the transition section.
  • a relatively smaller diameter top peripheral flange 16 is joined to a relatively larger diameter side wall 17 of the main body section of the container by a transition section 18 which curves inwardly from the side wall 17 to the flange 16.
  • the seam shown in more detail in Figure 2C is located at the base of the neck of the container above the transition section 18 of the lower portion 14.
  • the upper portion 11 or neck portion of the container includes a spout 12 at its top and a generally vertical or sloped section 19 below the spout.

  • the upper portion 11 and lower portion 14 are joined at a hidden overlapping seam 21 between the peripheral flange 20 of the upper portion and the peripheral flange 16 of the lower portion.
  • hidden seam refers to a seam that is designed in such a way that it is less noticeable when viewed from common viewing angles. This hidden characteristic can arise from the seam being obscured from view or from the seam being located at certain points relative to the overall bottle design such that the viewer's eye is not attracted to the seam. Such seams may be visible from certain viewing angles but in the context of the overall shape of the container, the seams of the present container are less apparent to a casual observer.
  • the peripheral flange 20 of the upper portion 11 overlaps an exterior surface of the peripheral flange 16 of the lower portion as shown in Figure 2C.

  • the diameter of the peripheral flanges 16 and 20 are substantially smaller than the outside diameter of the main body section of the container.
  • the diameter of peripheral flanges 16 and 20 in this embodiment may range from about 2.5 centimeters (1 inch) to about 5 centimeters (2 inches), but are preferably less than 3.8 centimeters (1.5 inches) in diameter and are shown at about 3.5 centimeters (1.4 inches) in diameter in the example shown in Figure 2.

  • the spout 12 at the top of the upper portion 11 has a generally cylindrical central part 24 and includes a pouring opening 13.
  • the generally cylindrical central part 24 may include threads as illustrated in Figure 1 or be smooth as illustrated in Figure 2.
  • the upper part may include a curled seal rim 23 that surrounds the pouring opening and may include a small ledge 25 about the curled seal rim as shown in Figure 1.
  • the container may have a neck ring 26 that protrudes either out of the container as shown in Figure 1 A or 2 A or into the container (not shown), or a combination of both (not shown) that is used to transport the container in a plant and/or be used as a load bearing point during the closing operation.
  • this neck ring 26 may be required to keep the container from collapsing because of axial loads that the whole container would otherwise be subjected to during closing. Closing refers to the operation of applying the closure to the container. Also, because the container would most likely be top heavy and/or easily tipped over, the neck ring may provide an alternate way to transport the container in a plant.
  • Closures generally include a top panel and a rim shaped to extend downward from the top panel around the spout.
  • the rim includes a generally circular lower edge.
  • the closure may be held onto the spout by means known in the art such as screw threads.
  • Metal or plastic threaded closures suitable for use on metal containers are described in US patent 6,010,026 the disclosure of which is incorporated herein by reference.
  • closure may be crimped around the sealing rim of the spout.
  • crowns Closures of this type, often referred to as crowns, are well known in the art. Some crowns are designed to be removed by rotating the crown, some must be removed by prying up on one side and some are scored so that they can be easily pulled apart. All of these types are well known to persons skilled in the art of metal containers.
  • the joint between the body portion 14 and the neck portion 11 of the container is formed by overlapping the peripheral flanges 16 and 20 of the respective portions.
  • Adhesive material may be applied to one or both contacting flange surfaces. If the peripheral flange 16 of the body portion 14 overlaps the peripheral flange 20 of the neck portion 11, adhesive is applied to either or both the interior surface of the body portion peripheral flange 16 and the exterior surface of the neck portion peripheral flange 20. If the peripheral flange 20 of the neck portion 11 overlaps the peripheral flange 16 of the body portion 14, then adhesive is applied to either or both the exterior surface of the body portion peripheral flange 16 and the interior surface of the neck portion peripheral flange 20.
  • the body portion of the container steel or aluminum, provided in sheet or coil form is lubricated and cut into pieces for subsequent operations. An individual piece, or blank, is then cupped to provide the initial shape of the container. Cupping and subsequent formation of the base and sidewalls of the body portion may be formed by a deep drawing process that is well known in the art of producing aluminum beverage cans. A variation on the known deep drawing process can also be utilized which avoids the formation of a transverse flange at the top of the body portion.
  • the process variation uses induction, spinning mandrels, or water pressure to force the base and sidewalls into a die representing the desired shape of the container.
  • Subsequent forming processes include ironing, which is well known in the art, to extend the length of the sidewalls of the body portion.
  • the upper edge of the formed body portion is then trimmed to a uniform height. Ears created by the ironing process and any other excess material is removed in a trimming step.
  • the formed body portion is washed and dried and finishing procedures are performed which may include: decorating, varnishing, coating, sizing, inspection, and shaping.
  • the body portion is then ready for adhesive connection to the top portion of the container.
  • the upper portion is formed separate from the lower portion.
  • the first step in forming the upper portion from sheet metal is to blank or cut a round disc from a metal sheet and to draw a low cylindrical boss in the center of the disc.
  • An annular flange circumscribes the boss.
  • This blanking and drawing is preferably performed in one single operation but may comprise two operations.
  • Application of this invention to the manufacture of steel tops and cans may require different tooling due to the different properties of steel, e.g., strength and formability, as compared to aluminum.
  • the next steps are to redraw the boss to increase its height and reduce its diameter. It may be necessary to redraw the boss two or more times to form progressively higher bosses with progressively smaller diameters without tearing or wrinkling the metal.
  • the optimum number of redraws will depend on several factors including the gauge, temper, and formability of the metal, coatings on the metal, and the diameter of the spout.
  • the outer diameter of the flange is preferably not affected by the redraw operations. It is desirable to maximize the reduction taken in each redraw in order to minimize the number of redraw operations. Conversely, the percent reduction must not be so great as to cause tearing or wrinkling of the metal during such redraw.
  • a center portion of the end wall of the boss is then removed by a blanking or piercing operation in a manner well known in the art and the cut edge around the opening has been wiped upwardly to extend the length of the boss and leave an upwardly projecting flange around the opening in the boss to be formed into an outwardly curled or folded bead.
  • the cut edge of the boss can be wiped down for subsequent forming into an inwardly curled or folded bead.
  • the upper portion and/or lower portion could also be formed of molded plastic by processes well known in the art
  • FIG. 2A shows upper portion 11 after it has been trimmed around its lower peripheral edge and reformed into a pouring spout 12 with long neck portion 19 and an outwardly extending curvilinear flange 26 around the lower peripheral edge of the spout 12.
  • the flange 26 is designed to facilitate handling and attachment of a closure to the open end of the spout.
  • FIG. 2A further shows a curled bead 23 around the top edge of the spout 12 on the upper portion 11.
  • the bead 23 is shown curled outwardly but can also be curled inwardly for some applications.
  • An outward curl should minimize the possibility that the terminal or cut edge of metal in the bead might be contacted by the contents of a container on which a spout is secured. The outward curl will also minimize the possibility that beverage in the container might be trapped in the bead.
  • An inwardly-curled bead may offer advantages such as formability, aesthetics or the like.
  • FIG. 2B shows the lower portion 14 of the container.
  • the lower portion 14 of the container 40 may be made entirely of one piece of thin metal such as 3004, 3104 or 3204 H-19 aluminum alloy.
  • the lower portion 14 before being necked is typically a drawn and ironed (D&I) can body except that it may have a top "thick wall" portion adapted to be necked into the transition section 18 of the lower portion.
  • the thick wall portion is not ironed as much as, and is therefore thicker than, the lower portion of the sidewalk
  • the thick wall portion is more formable into a transition section 18 in that the thicker metal can be formed with less wrinkling or other undesirable deformation.
  • the thick wall extends to the top of the lower portion 14 which is the length of the transition section 18 and the adjacent mating flange (necked in portion) 16 for subsequent joining to the upper portion 11 of the container.
  • a typical drawn and ironed (D&I) lower portion 14 may have metal of about (0.0166 inch) in the bottom profile 15, a thickness of about 0.147 millimeters (0.0058 inch) in the main body section, and a thickness about 0.203 millimeters (0.0080 inch) in the transition section 18.
  • Such lower portion 14 may have a diameter of about 6.033 centimeters (2.375 inches) and a height of about 16.51 centimeters (6.5 inches) to hold 354 milliliters (12 fluid ounces) or a diameter of about 6.71 centimeters (2.64 inches) and a height of about 15.24 centimeters (6.0 inches) to hold 590 milliliters (20 fluid ounces).
  • Other D&I can bodies for use with this invention may have metal thickness of about 0.203 to 0.508 millimeters (0.008 to 0.020 inch) in the bottom profile 15, a thickness of about 0.114 to 0.165 millimeters (0.0045 to 0.0065 inch) in the thin wall portion 17 and a thickness of about (0.0045 to 0.0085 inch) in the transition section 18.

  • FIG. 2B requires at least 10, and preferably 20 to 30 or more necking operations in order to form a transition section 18 on an aluminum can body having a diameter of approximately 3 inches down to a mating flange which is adapted to be joined to a upper portion similar to long neck upper portion shown in Figure 2A.
  • To form a transition section on a 3 inch diameter lower portion to join to top sections of larger diameters would require fewer necking operations than are required for the long neck upper portion illustrated in Fig 2 A.
  • the lower portion illustrated in Figure IB does not require any necking operations.
  • FIG. 1 is a cross-section through the container 10 without details necessary for attaching a closure to the top thereof.

  • Films for making labels and shrink wrap sleeves and related design services are available from Lawson Mardon Corporation. If only part of the container is covered the surface on one side or the other of the seam should be covered for a substantial distance, or the surface on both sides of the seam should be covered for a substantial distance. This tends to hide the seam in the decorative elements or draw the observer's attention away from the seam and thus make it less apparent. This is particularly applicable where the upper portion of the container is formed by a different process than the lower portion.
  • the lower portion will have a substantially brighter as formed surface finish than the upper portion. This difference in surface finish will naturally draw attention to the presence of the seam. However, if the container surface is covered as described above, then the separation that is visually created between the brighter and duller surface finishes reduces the impact of the difference on the casual observer.
  • the upper portion of the container is formed from bright sheet metal and the bottom portion is formed form sheet metal having a conventional surface finish.
  • the bright sheet retains some of its brightness and thus the as formed surface finish is more similar to the D&I surface finish on the lower portion of the container.
  • Bright sheet aluminum useful in the present invention is commercially available or can be produced by chemically brightening the surface of aluminum sheet by dipping or spraying the sheet with nitric acid according to known brightening methods.

Abstract

La présente invention concerne un récipient en deux parties comprenant un joint périphérique caché. Le joint entre la partie supérieure et la partie inférieure du récipient est formé de bords appariés formés sur les parties supérieure et inférieure du récipient et se trouve effectivement caché à la vue du fait du positionnement du joint à la base du goulot pour des récipients ayant un goulot effilé relativement long situé au-dessus d'une partie de corps principal à diamètre relativement plus large ou du fait du positionnement du joint juste au-dessous d'un épaulement à diamètre relativement plus large situé à proximité de la base de la partie supérieure du récipient de sorte que le joint soit visuellement masqué par la partie d'épaulement. Des techniques de finissage et de décoration complémentaires permettant de réduire la visibilité du joint sur un tel récipient sont également présentées.
