Definitions

  • ABSTRACT on THE DISCLOSURE A safety closure wherein the container has an oval neck with threads thereon with ratchet members interposed within the threads on the short sides of the oval and a cap of a deformable material having threads normally mating with those on the short side of the oval and having ratchets around its periphery mating with and opposing the ratchets on the neck, said cap being deformable to an oval configuration whereby the mating ratchet members are released and the threads in the cap are brought into contact with the threads on the long side of the oval neck whereby the cap can be partially unscrewed and can be fully unscrewed by successive repetitions of said movement.
  • both the container and cap are easily molded to the desired configurations so that the safety closure of the present invention need be no more expensive than a conventional closure. Further, there is not a single release motion for unscrewing the cap of the present invention, as is brought out in detail in the specification, but instead, a series of coordinated movements is required to fully remove the cap so that it is almost impossible for a child to accidentally stumble on to the secret and remove the cap.
  • FIGURE 1 is an exploded, perspective view of a container and cap embodying the present invention.
  • FIGURE 2 is a section on the line 2-2 of FIGURE 1.
  • FIGURE 3 is a section on the line 3-3 of FIGURE 1.
  • FIGURE 4 is an enlarged section through the neck and cap showing the parts in a normally unstressed, locked condition.
  • FIGURE 5 is a section similar to FIGURE 4 but showing the parts in the stressed condition necessary to achieve opening of the container.
  • FIGURE 6 is a side view, with the closure in section, of a device embodying the present invention.
  • a container having a neck, generally designated 9, and a cap, generally designated 11.
  • the container 7 forms no part of the present invention and can be in the form of any conventional container, such as a glass or plastic bottle, a metal can of any configuration or the like.
  • the neck 9 is of generally oval configuration so that the neck has two short sides 13 and 15 and two long sides 17 and 19.
  • the sides 17 and 19 are substantially flat but this is not necessarily so since they can be curved slightly as in a normal oval.
  • the sides 13 and 15 if continued would form a circle onto which the cap 11 would fit.
  • the neck 9 is provided with one or more threads 21 which may be in the form of a single or a double thread.
  • the single tread is safer but requires a longer time to remove the cap while a double thread is faster and under most conditions provides a sufiicient safety factor.
  • the cap portion 11 has threads 26 therein, generally mating with the threads 21 on the neck. Interposed between the threads in the neck are a series of ratchet members 28. These extend completely around the periphery of the inside of the cap and normally seven or eight are employed, although other numbers might be used.
  • the cap Since the neck is oval and the cap is round, the cap will not completely engage the threads of the neck but will normally engage only those on the short sides of the oval, as is best seen in FIGURE 4. At the same time, some of the ratchet members of the cap 28 are in engagement with either or both of the opposed ratchet members 22 and 24 on the neck. Thus, because of the opposed relationship of the ratchet members, it is obvious that the cap cannot be unscrewed. Further, because of the mating action of the threads, the cap cannot be pulled directly off.
  • the cap is distorted into the shape shown in FIG URE 5 or as is shown in phantom in FIGURE 1.
  • the ratchets 28 are now released from the ratchets 24 and 22 of the neck, while at the same time the threads of the cap are squeezed inwardly so that they now engage the threads on the long sides 17 and 19 of the oval.
  • the cap In this position, the cap can be unscrewed for approximately one-fourth turn, but as the thumb and finger approach the edges between the long and short sides of the oval, the shape of the distorted top' will change, again causing the ratchets to engage and stop further rotational movement. When this happens, it is necessary to repeat the operaton so that a large number of coordinated squeezing and twisting movements are necessary before the cap can be unscrewed. These coordinated squeezing and twisting movements are normally beyond the movements which a child can exercise and it would be most difficult for a child to open the container by a series of accidental movements.
  • the cap can be easily replaced merely by screwing it on in the manner of a conventional cap since the ramplike shape of the ratchets is such that as one attempts to screw on the cap, the top merely distorts sufiiciently for the ramps to clear.
  • the neck of the container can be made of any material such as glass, metal, plastic or the like which is normally hard enough to serve its intended purpose.
  • the cap is preferably made of a soft, yieldable plastic such as a polyolefin, although a springly metal could be employed for the purpose.
  • a safety closure including a container having a threaded neck and a cap for said neck comprising in combination:
  • said cap being deformable by pressure therein whereby said cap assumes an oval configuration releasing the ratchets and engaging the cap threads with the threads onthe long sides of the oval whereby said cap can be unscrewed for a small fraction of a revolution and can be fully unscrewed by successive repetitions thereof.
  • each short neck side has a ratchet thereon.
