Definitions

  • This invention broadly relates to a closure for sealing an opening in an article, such as a container.
  • the invention concerns an anti-choke closure that permits the passage of air (fluid) there through should the closure by chance become lodged in a narrow passageway such as the throat of a child or pipe.
  • a problem with small caps and other types of small closures for containers and tubes is that they can be ingested by a child and become lodged in that child's throat. In such an instance, the child could choke to death.
  • a related problem is that small closures can become lodged by accident in a pipe and thus prevent fluid (gas or liquid) from flowing through the pipe. In such an instance, the blockage could cause the buildup of pressure, flooding or leakage, or damage to the pipe or related machinery.
  • the present inventor has now developed a closure for an article that minimises or overcomes a problem referred to above.
  • a closure for sealing an opening in an article comprising:
  • a sealing region extending along the body for sealing an opening in the article; and at least one flow passage extending through the body at a location other than through the sealing region that permits the flow of fluid through the body.
  • the closure may seal the opening of any suitable type of article in any suitable way.
  • the article may be, for example, a pipe, tube, container or toy.
  • the article is a container and the opening is located in a neck of the container.
  • the closure is of a size that is ingestible by a child and the flow passage allows the flow of air there through should the closure become lodged in a throat of the child.
  • the closure may allow the flow of fluid (liquid or gas) there through such that the pipe or tube is not fully blocked/choked.
  • a sealing region extending along the body for sealing a container opening; and at least one flow passage extending through the body at a location other than through the sealing region that permits the flow of air through the body should the closure become lodged in a narrow passage, such as a child's throat.
  • the body may be of any suitable size, shape and construction, and may be made of any suitable material or materials.
  • the body may have an inner surface and an outer surface.
  • the body may have a
  • the body may have one side wall, in which case it will be circular.
  • the side wall may be rectangular, hexagonal, octagonal and so forth when viewed in plan.
  • the side wall may have a grip to facilitate handling by a user.
  • the side wall preferably extends substantially perpendicularly downwardly from the top wall. If desired, the side wall may only extend downwardly from the top wall in the general direction of the article, so as to minimise the overall length of the closure.
  • the top wall may be substantially planar/flat so as to further minimise the overall length of the closure (ie. so that it can be squat rather than long).
  • the sealing region may be of any suitable size, shape and construction, and may be made of any suitable material or materials.
  • the actual form of the sealing region may depend on whether the article/container contents are pressurised or non-pressurised.
  • the shape of the sealing region may depend on the shape of the opening that the closure is to seal.
  • the sealing region when viewed in plan, may be circular, rectangular, hexagonal, octagonal and so forth.
  • the sealing region is provided by an inner surface of the top wall of the closure, such as a substantially planar surface, that engages a rim/neck of the article/container opening.
  • the sealing region is provided by a ring extending substantially perpendicularly from the top wall, in which case the ring engages either an inner surface of a neck/rim of the article/container or an outer surface of the neck/rim of the article/container (or possibly both if the ring has an annular groove).
  • the sealing region may be provided by a plastic or rubber insert that extends along the top wall within the body.
  • the insert may be, for example, in the form of a disk or ring (o-ring), a wad of sorts.
  • the insert may be press- fitted or adhered to the top wall.
  • the sealing region of this embodiment is particularly suited for sealing pressurised contents.
  • the sealing region is provided by both an inner surface of the top wall of the closure and a ring extending substantially perpendicularly of the inner surface, and both the inner surface and ring engage a neck/rim of the article/container opening.
  • the inner surface of the top wall may be substantially planar, concave or convex, provided that it can seal the article/container opening.
  • the at least one flow passage may be of any suitable size and shape. It may be in the form of a round opening or a slit, for example. It may extend through the top wall and/or side wall of the body.
  • the closure has a plurality of flow passages. More preferably, the flow passages are spaced about a circumference of the top wall. Even more preferably, flow passages in the form of slits are regularly spaced about a circumference of the top wall where the side wall meets the top wall.
  • the flow passage or passages preferably allow sufficient air flow so that the child cannot choke to death or so that the closure can be dislodged before the child would normally choke to death.
  • the flow passage or passages allow sufficient air flow through the body regardless of the actual orientation of the closure within the child's throat (or pipe if in an industrial or domestic setting).
  • the flow passage or passages each extend through the top wall and side wall of the body.
  • the closure may comprise a connecting mechanism connectable to the article/container so that the sealing region seals the article/container opening. Any suitable type of connecting mechanism may be used.
  • the closure may be screwed, snap-fitted, friction-fitted, crimped or otherwise coupled with the article/container (e.g. bayonet coupling).
  • the closure may be of unitary construction or may comprise separate connectable pieces.
  • the closure may be made of plastics material or metal, such as aluminium.
  • the closure is made of a single piece of moulded plastics material, preferably food-grade plastic. If the closure is a complicated part, eg. a flip-top cap, then the flow passage(s) may extend all of the way through the secondary parts, thus allowing flow without hindering the sealing or user-friendliness of the article/container.
  • the connecting mechanism may comprise a thread that screws to a like thread of the container.
  • the thread winds around the inner surface of the side wall of the body.
  • the connecting mechanism may comprise a flange extending from the side wall that snap-fits to a complimentary formation of the article/container.
  • the side wall of the body may friction fit to a neck/rim of the article/container.
  • the side wall of the body may be crimped to a neck/rim of the article/container.
  • the closure may comprise other known features of commercially available closures such as, for example, a tamper-evident collar or a. secondary seal such as a shrink-sleeve.
  • an anti-choke closure for sealing a container opening, said closure comprising:
  • a body comprising a top wall and at least one side wall extending from the top wall; a container-sealing ring extending along the top wall for sealing a container opening;
  • a connecting mechanism connectable to the container so that the container-sealing ring seals the container opening
  • a plurality of airflow passages extending through the top wall and/or the side wall at a location other than within the container-sealing ring so as to allow the flow of air there through.
