Definitions

  • This invention relates to a closure for a container.
  • Containers are commonly used to contain liquids, powders, and other consumables requiring storage or transportation.
  • the containers are supplied with a co-operating closure to reduce the risk of a user spilling the contents should he accidentally jar or tilt the container.
  • the closure is reusable. However, in some instances, e.g. bottled alcoholic beverages, the container remains open once a user or third party has removed the associated closure.
  • a closure for a container, comprising a closure member and a key member, the closure member including an opening formed in communication with a concealed sealing member, the sealing member being moveable between a closed position towards which it is resiliently biased and an open position, the opening defining a conduit for at least one of dispensing the contents of the container or adding contents to the container; the closure member further including an access channel in communication with the sealing member; and the key member including an engagement portion that is co-operable with the access channel, whereby the engagement portion is moveable within the access channel, so as to move the sealing member into the open position, when the closure member and the key member are releasably engaged together.
  • a key member permits a user to control access to the contents of the container. Such access can be limited to the user himself or to one or more additional, so-called, "key holders".
  • a further advantage of this arrangement is that the key member permits repeated access to the contents of the container without the need to remove the closure member or modify the closure member after each period of access.
  • one of the engagement portion and the access channel includes at least one protrusion and the other of the engagement portion and the access channel includes at least one co-operable first recess.
  • the provision of at least one co-operable protrusion and recess pair allows for the generation of a large number of differing combinations of closure member and key member. In this way only a specific key member will provide access to a containers contents via a given closure member.
  • one of the engagement portion and the access channel includes at least one second recess in communication with a respective first recess and extending at an angle therefrom, the or each second recess including an elongate member moveably secured therein, the elongate member extending through one of the engagement portion and the closure member whereby the elongate member is moveable by a respective protrusion into engagement with the sealing member, so as to move the sealing member into the open position, when the closure member and the key member are releasably engaged together.
  • At least one elongate member disposed between the key member and the sealing member provides an additional layer of security for the closure.
  • the use of at least one elongate member to move the sealing member prevents a third party from inserting an object into the access channel in an attempt to move the sealing member to the open position.
  • closure member is formed integrally with the container; and/or removably or fixedly secured to the container.
  • the container includes a tamper-evident member disposed between the closure member and the container.
  • closure member provides for a closure that can be attached to existing containers without the need for modification of the container.
  • closure member allows the closure member to be formed as part of the container during the container manufacturing process.
  • one of the closure member and the key member includes at least one first engagement member and the other of the closure member and the key member includes at least one further engagement member that is engageable with the first engagement member, so as to permit the releasable engagement of the key member and the closure member when the sealing member is in at least one of the open position and the closed position.
  • first and further engagement members allows a user to temporarily retain the key member and the closure member in engagement with one another. Such temporary engagement can occur with the sealing member in either the closed position or the open position. This helps to prevent a user from misplacing the key member during use.
  • the closure member includes a shield member that conceals the sealing member, the shield member permitting the dispensing of the contents of the container or the addition of contents to the container, but preventing a person from moving the sealing member via the conduit.
  • the shield member is secured within the conduit.
  • the shield member includes at least one leg extending therefrom, the or each leg being receivable within a respective cavity in the sealing member, whereby the shield member is moveable against a biasing force between a position displaced from the sealing member and a position adjacent to the sealing member.
  • at least one said leg includes a first locking member that is engageable with a further locking formation in a said cavity, whereby the shield member is lockable in the position adjacent to the sealing member so as to prevent movement of the sealing member to the open position.
  • the conduit includes at least one retention member, the or each retention member preventing removal of the shield member. This prevents a user or third party forceably removing the shield member from the closure member.
  • the sealing member includes a substantially rigid frame, the frame including at least one spring member protruding therefrom, the or each spring member resiliently biasing the sealing member towards the closed position.
  • the sealing the sealing member further includes a first sealing portion co-operable with the conduit in the closure member to seal the conduit, and a second sealing portion arranged to prevent the dispensing of the contents of the container and the addition of contents to the container via the access channel.
  • the first sealing portion includes a stopper and the conduit includes a co-operable seal, the stopper and the seal combining to seal the conduit.
  • Such features provide for a sealing member that is easy to manufacture from readily available materials.
  • the closure member has a substantially circular cross-sectional profile and includes a liner; the access channel has a substantially circular cross-section and is disposed between the liner and an outer wall of the closure member; and the engagement portion of the key member defines a hollow tube having a substantially circular cross-section.
  • the key member includes one of a spout; a nozzle; and a nipple.
  • a substantially circular closure is familiar to users and is comfortable to use.
  • closure member includes a removeable cap. This helps to keep the conduit and access channel clean when the closure and container are not in use.
  • the closure member includes at least one tamper-evident seal, the or each tamper-evident seal sealing at least one of the opening and the access channel of the closure member.
