Definitions

  • This invention relates to a closure for a container, and particularly to, a container used in the water bottling industry for water dispensers and water coolers, such as a five- gallon container.
  • a typical large container has an upstanding neck, defining an opening for the container, and has an external snap formation for engagement with a closure.
  • Closures for the large containers are also known and typically include a roof portion, a shoulder portion depending downwardly from the roof portion, and a skirt portion depending downwardly from the shoulder portion. Internally, the closure has a snap bead, located generally at the intersection between the skirt portion and the shoulder portion, for complementary engagement with the snap formation on the container neck.
  • the closure may either be a "flat-roof or a "non-spill" closure, both of which are known in the industry.
  • a flat-roof closure has a generally flat, closed-off roof portion, which is in the form of a disc. The flat-roof closure therefore needs to be removed from the neck of the container in order to discharge the fluid or contents of the container.
  • many of the dimensions for closures are required to lie within relatively tight tolerances, in order for the closures to provide an effective liquid-tight seal on a range of conventional container neck finishes. Accordingly, design freedom for such closures is limited.
  • the well is closed at its bottom end by an integrally attached bottom portion.
  • the dispensing device includes a feed probe having a sharp pointed upper end and a lower end that facilitates draining into the dispenser's reservoir.
  • the probe is positioned axially within a cylindrical sleeve, which receives the inverted container neck (with cap attached) and snugly holds the container upright in its inverted position.
  • the probe pierces the bottom portion of the closure well allowing water to flow out of the container into the dispenser.
  • the '188 patent does not enjoy significant commercial acceptance for a number of reasons.
  • the sharpness of the upper end of the probe can be a safety concern. Possible attempts to soften the end would lead to increased difficulty in piercing the bottom portion of the closure well. This situation was aggravated in that the bottom portion of the closure well is essentially solid, having no structural feature to promote frangible penetration of the by the probe.
  • the dispensing probe rather than being sharp to promote piercing, is designed to be complimentary to structural features incorporated into a cap, plug, or sliding member (hereinafter referred to as a "secondary cap") that initially seals the central closure well.
  • a secondary cap When the container is inverted onto the dispenser, the complimentary features on the probe and plug interact to initially attach the secondary cap to the probe.
  • the secondary cap As the container moves further downward onto the probe, the secondary cap, still attached to the probe, is moved further into the container, upon which a dispensing port on the probe becomes exposed to the fluid contents of the container. The contents would then flow freely by gravity through the dispensing port to the inside of the probe and then to the dispensing reservoir.
  • the secondary cap When it is desired to remove the partially filled or exhausted container, the secondary cap, still attached to the probe, would be repositioned into a sealing position with the closure well. As the container is removed from the dispenser, the secondary cap is released from its attachment to the probe at which point the central closure well is resealed.
  • a first of the concepts incorporating a frangible opening of the base portion of a closure well was taught in U.S. Patent 5,687,865 the entire contents of which are herein incorporated by reference.
  • the '865 patent teaches at least one frangible line or line of weakness extending across the base portion of a closure well.
  • a projecting member was positioned adjacent one of the frangible lines. The projecting member was initially contacted upon insertion of the probe to concentrate force and facilitate initial tearing of the frangible line. The projecting member reduced the amount of downward force required to initially rupture the frangible line.
  • the '865 patent further teaches a conical geometry for the opening portion.
  • U.S. Patent 6,308,849 herein incorporated in its entirety by reference, discloses a container closure with a central receiving bore closed by a base having frangible lines.
  • the base comprises two frusto-conical portions extending in opposite directions. Insertion of the probe causes the base to turn "inside-out" as the three frangible lines rupture.
  • the '849 patent teaches that this arrangement helps promote return of the three separate petals formed on probe insertion to a sealing position upon removal of the container from the probe.
  • the instant invention offers the art an improved closure for a container and a dispensing system for large liquid containers such as the 5 gallon water container.
  • the closure includes a central well sized to sealingly receive a probe such as those currently employed on many 5 gallon water dispensing apparatus.
  • the well has an open end for receipt of the probe and an integrally molded closed base structure.
  • the closed base structure allows facile penetration by the inserted probe for the dispensing of fluid. Upon removal of the probe, satisfactory reseal is achieved through the unique design aspects of the base structure.
  • Various aspects of the novel design aspects are embodied in the disclosure herein.
  • a cap for a container used on a water dispenser is provided to include a well extending from a roof portion into the cap.
  • the well has a wall structure terminating at a base structure.
  • the base structure has a shape defined as an annular rim connected to the wall structure and a frusto-conical member depending from the annular rim and extending in a direction towards the roof portion.
  • the frusto-conical member has an edge that terminates to a disk shaped member.
  • the cap may have a dome depending from the annular rim that extends towards the roof portion.
  • the cap may include a convex member depending from the annular rim and extending in a direction towards said roof portion.
  • the base structure may further include at least one frangible lines defined thereon.
  • the frangible lines may traverse the base structure and/or intersect one another.
  • the cap may further include scored sections to help prevent damage and rupturing of the well during probe insertion.
  • the scored section may include a portion on the base structure and/or a portion on the wall structure.
  • the frangible lines would be defined on the frusto-conical member, dome, convex member, and/or base structure.
  • the base structure would include at least two sections.
  • the two sections would include a dominate portion that overlaps or is coincident with a subservient portion defined by another one of said sections, such that the overlap or coincidence causes the base structure to be sufficiently sealed during non-use.
  • the two sections are also deformable during penetration of the base structure by a probe defined by the water dispenser, such that the two sections deform to separate and allow liquid within said container to dispense.
  • the base structure may also include four sections wherein two of the sections would have dominate portions overlapping or coincident with two subservient portions defined by the other two section.

Obviously, if the well 60 were to comprise multiple score lines, a number of deformable sections would be formed as compared to the "clam-shell” description associated with a single line. When the probe 16 is eventually removed, the "clam shell” arrangement will close somewhat because of the tendency of the plastic material to return to its original molded shape.
