Definitions

  • This invention relates to a resealable container for retaining carbonated or noncarbonated beverages. More particularly, the invention is directed to a plastic can having a flip-back reclosable seal that covers a drink through opening that provides access to the beverage.
  • the metal can is the most common container used for retaining carbonated and noncarbonated liquids.
  • Conventional metal cans may be constructed having a two or three part structure.
  • a three-piece metal container generally includes a cylindrically shaped sidewall, a bottom wall, and a top wall.
  • the sidewall is fabricated from a single rectangular sheet of metal.
  • the metal is formed into a cylindrically shaped structure using known metal forming and seaming techniques.
  • the cylindrically shaped structure includes an open top and bottom surface. The open surfaces are closed by affixing a top and bottom, respectively, thereto using known seaming technology.
  • the top surface is generally attached after the bottom surface has been affixed to the cylindrically shaped structure and the cylinder has been filled with the desired liquid contents.
  • a two-piece can-type container typically includes an integrally formed sidewall and bottom surface and a separate top surface.
  • the fabrication process for this structure may include drawing and redrawing a metal sheet or drawing and wall ironing the metal material. Using either process, a single metal sheet is used to configure a cylindrically shaped sidewall integrally formed with the bottom surface. The longitudinal edges of the sidewall are joined using seaming technology so as to form an open top cylinder. Once the cylinder has been filled with a beverage, the top surface is affixed to the upper surface of the sidewall surface to close the open top. The top surface is attached to the upper edge of the sidewall surface using known seaming and/or press fit technology.
  • a typical two-piece aluminum can body may be formed from a 0.012 inch thick aluminum alloy sheet material.
  • the drawing and ironing process results in a sidewall thickness of approximately 0.004 inches and a bottom wall thickness of approximately 0.012 inches.
  • the upper rim wall portion is approximately 0.006 to 0.007 inches thick to enable seaming of the lid.
  • the top surface of the can generally includes an easy-open device such as a disposable pull-tab or a press-down-stay-on-tab mounted thereon.
  • an easy-open device such as a disposable pull-tab or a press-down-stay-on-tab mounted thereon.
  • These devices present several disadvantage. First, these devices are difficult to open, particularly for individuals having limited mobility and strength in their hands, as the tab generally lies flush against the top surface of the can and is often located within a recess formed in the top surface, making the tab difficult to grip and lift up. Second, there is no provision for closing the can once opened, and, finally, the content of the can cannot be viewed until the protective seal covering it has been removed. To address the resealability issue, prior art devices have used rotatable and nonrotatable overcaps that may be snap-fit or otherwise mounted onto a metal can-type container.
  • the tongue is folded about a hinge and inserted through a slot in the skirt.
  • the tongue includes a knurled portion that extends outwardly from the skirt once the body of the tongue has been inserted through the slot. The tongue is moved between a sealed and dispensing position by pressing down on the knurled portion with a finger or thumb of the hand holding the can.
  • Some disadvantages associated with these devices include: (1) the use of an element separate from the can for sealing purposes increases manufacturing costs and the likelihood of the closure being lost or damaged, (2) the presence of protruding surfaces extending from the body of the container that may interfere with the ability to stack the containers during shipping or in-store display, and (3) protruding surfaces that may be damaged or broken during shipment.
  • conventional metal cans may be constructed using two different materials.
  • the top may be formed using aluminum and the body formed using steel.
  • These containers tend to increase the cost of recycling, as the metal components must be separated during recycling.
  • the invention relates to an open topped container.
  • the container has the configuration of a conventional metal can; however, the container is fabricated from a plastic material.
  • the container comprises a body including a closed bottom surface and a sidewall surface extending upwardly from the periphery of the bottom surface, the sidewall terminating in a top surface remote from the bottom surface, wherein at least a portion of the top surface is open.
  • the container also includes a closure coupled to the top surface, the closure including a lid having a central portion and a peripheral depending skirt for engaging the body and closing the top surface; a movable reclosable flip-back lid formed in the lid, the reclosable flip-back lid releasably engaging the lid and having a free end and fixed end, wherein the free end is selectively moved from a closed position to an open position; and a hinge coupling the fixed end to the lid.

  • the container includes a tear-back flap formed on the lid adjacent the reclosable flip-back lid.
  • the closure supports an annular seal, which forms a liquid tight seal between the reclosable flip-back lid and the content of the container.
  • the closure may be held in an open position by configuring the lid so as to include a raised surface for mating with a recessed surface formed in the top surface of the movable reclosable seal, whereby the raised surface is received in and frictionally engages the recessed surface to hold the reclosable seal in an open position.

  • the container 10 includes a body portion 12 and a closure 14.
  • the body portion 12 defines the cavity that retains the beverage, and the closure 14 provides the closing surface for the body 12.
  • the body 12 includes a closed bottom surface 16, and, as best seen in FIG. 7, the bottom surface 16 preferably has a circular configuration having a raised center portion 18.
  • the center portion 18 may be fabricated with an increased thickness to reduce the likelihood of deformation or failure of the bottom surface 16 due to elevated pressures inside the container 10.
  • the bottom surface 16 also includes a downwardly extending annular ring 20 that is integrally formed with and surrounds the raised center portion 18.
  • the annular ring 20 imparts enhanced stability to container 10, permitting the container 10 to sit level when placed on a surface such as a table.
  • a cylindrical sidewall 22 extending upwardly from the perimeter of the bottom surface 16 is a cylindrical sidewall 22.
  • the sidewall 22 defines an open center 24 for retaining a beverage.
  • the cylindrical sidewall 22 terminates at a top surface 26 (FIG. 1), wherein at least a portion of the top surface 26 is open.
  • the top surface 26 has a conical configuration that tapers inwardly from the sidewall 22, forming a larger diameter end 28 contiguous with the sidewall 22 and an upwardly projecting smaller diameter end 30. As shown in FIG. 2, the outer perimeter of the smaller diameter end 30 supports threads 32.
  • the closure 14 closes the open top portion of the container 10.
  • the closure 14 is generally circular in configuration.
  • the closure 14 defines a lid 15 having a substantially planar top portion 34 and a downwardly depending peripheral skirt 36, the skirt 36 supporting threads 38 at the internal periphery thereof.
  • the top portion 34 is essentially planar, the top portion 34 supports a tear-back flap 40 and a movable reclosable flip-back lid 42, both of which have surfaces that project slightly upwards from the top surface 34.
  • the tear-back flap 40 includes a removable surface 44 and a pull ring 46.
  • the removable surface 44 is preferably a planar member, which is integrally formed with the top portion 34.
  • the removable surface 44 and the top portion 34 may be molded as a single structure or coupled together to form a unitary structure by ultrasonic welding or similar techniques.

  • the pull ring 46 preferably has a semi-circular configuration surrounding an open center. To facilitate access to the pull ring 46, the outer perimeter of the pull ring 46 projects slightly outwardly from the top surface of the removable surface 44. The pull ring 46 may be easily grasped by inserting a finger or other object through the open center. Additionally, the planar surface of the removable surface 44 includes a fixed end 45. A flexible hinge 54 couples the fixed end 45 to the top surface 34. A detailed view of the hinge 54 is provided in FIG. 10. The hinge 54 is integrally formed with the top surface 34, and is known in the plastics industry as a living hinge. Such hinges are common in the plastics industry and are formed using conventional techniques.
  • one technique for forming the hinge 54 requires forming a groove in the top surface 234, wherein the groove has a thinner wall thickness than that of the surrounding surfaces. This arrangement permits the surfaces adjacent the groove to bend in at least one direction.

  • containers 10, 100, 200 The exact dimensions selected for fabricating containers 10, 100, 200 will depend on the properties of the resin from which the containers 10, 100, 200 are fabricated, the type of beverage, carbonated or noncarbonated, retained thereby and the volume of liquid to be held by the containers 10, 100, 200. However, it will be appreciated that the containers 10, 100, 200 must be designed to withstand certain internal pressures, which will vary depending on the amount and type of beverage retained by the containers 10, 100, 200. With respect to carbonated drinks, normal internal pressure levels are caused by the carbonation in the beverage and/or the heat of pasteurization. The internal pressure may be increased significantly when the beverage is subject to high atmospheric temperatures and/or agitation.

  • the preferred materials are polyethylene terephthalate and Lexan, a trade name for a group of polyester formed from carbonic acid, for the body 12, 212 and polyethylene for the closure 14, 214. It will be appreciated that other materials having similar mechanical properties may be used.
  • Typical processes for molding the container 10, 100, 200 are injection and blow molding, vacuum forming and/or a modified version of stretch blow molding.
  • the preferred manner of forming the container 10, 100, 200 is injection molding, wherein the plastic material is injected into the mold using conventional techniques and procedures.
  • Another process for molding the body 12, 212 includes injecting the plastic material used to form container 10 onto a pin and rotating the plastic material to a blow molding station to be inflated, stretched and cooled. Selection of the appropriate blow molding technique is dependent upon the polymer viscosity at high and low shear rates, melt strength, strain recovery, crystallization kinetics and the thermal properties of the resin selected.
  • a similar process may be used to form the closure 14, 214.
  • Typical processes for forming the closure 14, 214 include injection molding and/or reaction injection molding modified to mold a resin with a mold configured to produce the constituent elements of the closure 14, 214.
  • the plastic material may be melted and a force applied to force or inject the polymer into a hollow mold cavity. Selection of the injection unit feed rate, pressure and the clamping unit for the mold are dependent upon the final characteristics of the resin selected.
