Definitions

  • This invention is in the field of closures for containers for consumer products. More particularly, the invention deals with closure devices for achieving child resistant characteristics.
  • Exemplary of the containers and closures developed by the art in response to this need is the closure and container shown in U. S. Patent No. 3,888,376.
  • This container and closure is in the class of child-resistant packages which feature latching and unlatching means carried by the threads of the closure and the container.
  • this class is beset by the problem of requiring very exact container and closure manufacture so that registration of the latching structure can be predictably effected.
  • the manufacturing standards required are oftentimes difficult to achieve when it is considered that the packager oftentimes purchases the containers from sources separate from the closures.
  • a safety closure for containers comprising a threaded neck portion, a cap provided with a multiplicity of threads cooperatively engaging the threads on the neck portion, means connected to the threaded neck portion for stopping the threading rotation of the cap onto the threaded neck portion at a predetermined position, and resilient liner means interposed between the underside of the top of the cap and the top of the neck portion.
  • An advantage of the container and closure of this invention is a low application torque, ability to give a tight seal, and easy opening for adults.
  • a disc liner acts as both a spring to maintain required vertical pressure and seal against a vacuum and normal environmental atmosphere.
  • Another advantage is that an odd shaped cap can be oriented to match a conforming container, e.g., a square cap can be aligned with the sides of a square container.
  • a conventional container 10 which, while preferably made of plastic, may be made of glass or suitable material.
  • the container has the usual neck portion 11 provided with threads 12 and 12a which, when the container is made of plastic, may be molded. Threads 12 and 12a have trailing edges 17 and 17a, respectively, which are generally parallel to the center line of the closure.
  • the two threads 12a have a stop 13 at the end thereof which together with surface 17a define gap 13a whereas the two threads 12 do not have a stop at the end thereof, although they do have surface 17 which contacts surface 16a in the locked position.
  • the closure of cap 14 has four harpoon-shaped threads 15 equally spaced at approximately 90 degrees apart.
  • the harpoon-shaped threads 15 have an arrowhead portion 16 thereon, the surface 16a behind the arrowhead 16 being generally parallel to the centerline of the closure and being designed to interlock in gap 13a as shown in Figure 6 in the "ghosted" thread 15.
  • the surface line of the top 16b of arrowhead portion 16 is generally parallel to the bottom 12b of threads 12 and 12a to reduce thread damage, as is the tail of thread 15.
  • the top of the neck has the usual bearing surface.18.
  • the underside of cap 14 has a depressed top portion 19 which can be molded in the cap when it is made of plastic or embossed in the cap when the cap is made of metal. Lying between the top 18 of the neck 11 and the depressed portion of the cap 14 is a liner 20. Liner 20 is made of some suitable resilient material which in conjunction with the depressed portion 19 of cap 14 seals the top 18 of container 10 to prevent any fluids flowing therefrom.
  • the top 18 of container 10 preferably includes a sealing surface 18a (see Figure 7).
  • Sealing surface 18a includes a flat portion 18b and a curved or radiused surface 18c. Both 18b and 18c cooperate to assure a tight seal.
  • Closures made in accordance with the invention can be attached to the container with a torque as low as 10 to 12 inch-pounds.
  • the leading edge of the threads 12a and 12 have a tapered surface 21 which acts in conjunction with arrowhead portion 16 of threads 15 to insure ease of threading.
  • the present invention provides a one-piece safety closure obtaining a positive lock against inadvertent opening.
  • sealing bands 25 and 26 are provided at the bottom of neck 11. These sealing bands 25 and 26 provide several functions. They help prevent the container from going out-of-round during high application torques and they serve as a bacteria baffle.
  • an odd-shaped container having a corresponding odd-shaped cap is feasible in accordance with the present invention because the cap can be oriented and aligned with the sides of the container to make the combined cap and container symmetric and esthetically pleasing.
  • a square cap can be fitted to a square container by positioning stops 13-13 in the appropriate place on neck 11.
