Definitions

  • ABSTRACT A safety closure for a container comprises inner and outer caps with ratchet teeth formed on the skirts of the caps for abutting and turning the inner cap on the container when a torque is applied to the outer cap in the application direction.
  • the ratchet teeth slide by each other without turning the inner cap.
  • a segmented ring forming a flexible dome on a central portion of one of the caps is flexed by a facing rigid central portion on the other cap thereby allowing radially extending teeth on the inner surface of the top end wall of the outer cap to move axially toward and into engagement with radially extending teeth on the upper surface of the top end wall of the inner cap.
  • This invention relates to a safety closure for a container which can be applied and removed readily by one having knowledge of how to manipulate the closure but is relatively safe from removal from the container by children.
  • the closure comprises inner and outer caps with ratchet teeth formed on the skirts of the caps for abutting and turning the inner cap on the container when a torque is applied to the outer cap in the application direction. When the outer cap is turned in the removal direction, the ratchet teeth slide by each other without turning the inner cap.
  • Safety closures of the foregoing kind have been com sharpally very successful; but for some uses, those who remove the closures from the containers express a desire that the amount of axial force or pressure required for removal be reduced. For example, housewives prefer to exert only a slight downward force and turning torque to open caps on containers. Because these safety closures of the foregoing kind have been made in large quantities and have met with wide commercial success, it is most desirable that only minimal changes be made which do not result in large scale retooling'or new modes of manipulation for removal and replacement but which'reduce significantly the amount of axial force required for removal of the closure from the container.
  • an object of the present invention is to provide a safety closure of the foregoing kind which requires less downward force, is contrasted to prior art safety closures of this kind, for engaging the interlocking teeth and for facilitating removal .of the closure from the container.
  • FIG. 1 is an enlarged, perspective view of a safety closure embodying the novel features of the invention
  • FIG. 2 is an exploded perspective view of inner and outer caps of the dispenser closure of FIG. 1 with a portion of the skirt of the outer cap broken away;
  • FIG. 3 is a bottom view of the outer cap without the inner cap being present
  • FIG. 4 is a cross-sectional view taken substantially along the line 44 of FIG. 1;
  • FIG. 5 is a fragmentary plan view of the top of the inner cap.
  • a safety closure 11 which comprises an outer cap 12 overlying an inner cap 14 with the inner and outer caps being coaxially aligned.
  • a container fasteneing means 17 such as a spiral screw thread 18.
  • a series of ratchet teeth 19 on the skirt 15 of the inner cap project radially outwardly for interlocking engagement with ratchet teeth 20 on an inner side of a depending generally cylindrical skirt 21 for the outer cap 12.
  • tooth abutment walls 23 on the ratchet teeth 20 of the outer cap 12 abut and interlock with similar tooth abutment walls 25 on the ratchet teeth 19 of the inner cap and continued turning of the outer cap screws the inner cap onto the container.
  • the outer cap 12 is rotated in the removal direction (which is clockwise as viewed in FIG. 2) inclined susfaces 27 of the outer cap ratchet teeth 20 slide over inclined surfaces 29 of the inner cap ratchet teeth 19 without an unscrewing of the inner cap. That is, the torque exerted on the inner cap teeth by the sliding outer teeth is not sufficient to overcome the frictional resistance between the thread 18 and the container thread.
  • a child or other person who merely turns the outer cap on the inner cap will not unscrew the inner cap and gain access to the contents of the container.
  • the outer cap 12 and the inner cap 14 each had a dome similar to dome 39 shown on the inner cap 14, as shown in FIG. 4. More specifically, a downwardly projecting dome (identified by the numeral 9 in the patent) composed of a solid body of material was formed on the inner side of the outer cap top end wall with its lower rounded surface abutting the upper rounded surface of the dome on the inner cap and thereby holding the teeth of the outer cap above and spaced from the teeth of the inner cap.
  • This solid upper dome rigidified the central portion of top end wall with the result that an annular and teeth bearing portion of the top end wall had to be flexed by force applied between the outer supporting skirt and the inner dome in order to bring the teeth on the two end walls into engagement with each other.
  • the amount of force required to deflect the teeth was considered by some users to be too great for this prior art closure.
  • the amount of axial directed force required to flex the outer cap teeth 31 into engagement with inner cap teeth 35 is substantially reduced by providing, on a central portion 40 of the top end wall 33 of the outer cap an upper dome 41 constructed in a novel manner providing resilience while still providing means at the center of the inner and outer caps to space their respective teeth until sufficient downward force is exerted.
  • the upper dome 41 is formed as a segmented ring having flexible ring segments 43 projecting into abutment with the dome 39 on the lower cap 14 and deflecting readily with depression of the center portion 40 of the upper cap.
  • the ring segments 43 are thin in cross section and are flared outwardly from their upper to lower ends to facilitate their being cammed outwardly by the dome 39 with depression of the center portion of the top end wall 33. In this deflected condition, the ring segments are stressed and will provide a restoring force to lift the teeth 31 when the manually exerted downward force is released.
  • the outer cap 12 is formed in one piece by molding a relatively flexible resilient plastic such as polyethylene or polypropylene.
  • a relatively flexible resilient plastic such as polyethylene or polypropylene.
  • the top end wall 33 is made of a flexible material for deflecting with axially directed pressure.
  • the end wall 33 is integrally joined at a rounded comer 48 with the depending skirt 21.
  • a series of ra- I dially extending teeth 31 are integrally molded on the top end wall 33 and project downwardly from inner side 51 of the top end wall 33.
  • the teeth are elongated with lower bottom walls 53 disposed in a plane spaced from and parallel to the plane of the inner side 51 of the top end wall.
  • the teeth 31 are equally spaced from and angularly spaced about an axis through the center of this top end wall.
  • each of the downwardly projecting teeth is formed with a pair of vertical, parallel side walls 55 extending from inner rounded tooth ends 57 to outer rounded tooth ends 59.
  • the side walls 55 define therebetween triangular wedge shaped slots for the reception of the triangularly shaped lower teeth on the lower cap 14.
  • the teeth 35 on the inner cap 14 project upwardly from an upper side 60 of the top end wall 37 for the inner cap and are sized to be inserted into the slots between the teeth 31 of the outer cap 12.
  • the triangular shaped teeth 35 have narrow inner ends 62 and vertical side walls 63 which diverge outwardly to a wider arcuate outer wall 64.
  • the spaces between the side walls 63 of adjacent fingers 35 define substantially parallel sides of grooves or slots to receive the teeth 31 of the outer cap.
  • segmented ring means 41 for holding the caps 12 and 14 with their teeth 31 and 35 spaced, the ring segments 43 thereof rest on the dome 39 of the lower cap 14 so that the child or other user who merely rotates the outer cap will not remove the inner cap and closure from the container.
  • the illustrated segmented ring means is formed with three segments 43 which are separated from one another by vertically extending spaces 68 between adjacent segments.
  • the segments are integrally attached at upper arcuately shaped ends to the inner side 51 of the end wall 33 in a circular array about the axis of the outer cap; and the ring segments flare outwardly from these upper inner ends to free, lower and outer ends 70 which are arcuately shaped and in a circular array collectively defining a concave interior surface to receive the dome 39 of the inner cap in the center thereof.
  • the free ends 70 of the segments 43 project downwardly for a distance greater than the upper teeth 31 project downwardly, as best seen in FIG. 4, and will maintain the teeth spaced from one another until sufficient axial force is provided to cam their free ends 70 radially outwardly with a simultaneous downward deflection of the top end wall 33.
  • the segments 43 will readily deflect unlike the rigid upper dome used heretofore for the outer cap and result in less force required to displace the end wall 33. This is in contrast to the action in the prior art closures in which the axial pressure on the abutted domes resulted only in flexing of the end wall. That is, in the prior art closures of this general kind, the abutted domes served as a first fixed point and the corners 48 served as a second fixed point and defined therebetween a short span requiring a large force to deflect the annular section sufficiently to bring the teeth into engagement.
  • the tooth abutment walls 23 on the ratchet teeth 20 abut similar tooth abutment walls 25 on the inner ratchet teeth 19 to rotate the inner cap 14 to screw the thread 18 onto a similarly threaded portion of the container.
  • the ratchet teeth 20 on the outer cap 12 are generally triangular in cross section and project radially inwardly from inner surface 72 of the skirt 21.
  • the ratchet teeth 20 extend downwardly from upper ends positioned adjacent the end wall 33 to lower ends 71 which are spaced upwardly above the lower ring for the outer cap 12.
  • Each ratchet tooth decreases in cross-sectional area in the counterclockwise direction from its tooth abutment wall 23 to a trailing edge 73 which smoothly blends with the inner surface 72 of the cap skirt 21.
  • an inwardly projecting retaining ring 81 (FIGS. 2 and 4) is formed on the bottom rim of the outer cap 12 to project beneath a lower rim 82 for the skirt 15 of the inner cap.
  • the inner cap is forced inwardly into the outer cap 12 with the retaining ring 81 being flexed outwardly by the skirt 15 until the skirt rim is disposed above the retaining ring 81 which is then free to snap beneath the skirt rim 82 as shown in the illustration of FIG. 4.
  • the inner cap 12 is preferably molded from relatively hard non-yielding plastic material such as polystyrene, polypropylene, bakelite or the like.
  • the thread 18 therein is integrally molded in .the inner side wall of the skirt and the lower portion of the skirt is provided with a thicker cross section band 85 to reinforce the lower rim of the skirt.
  • This enlarged cross-sectional band 85 projects radially outwardly into the area between the retaining ring 81 and lower ends 71 of the ratchet teeth 20 on the outer cap 12.
  • the present invention provides a new and improved closure which requires less downward force to engage radially extending teeth on the outer cap with interengageable teeth on the inner cap to interlock the caps for turning together to release the closure from the container.
  • the ring 41 of resilient segments 43 may be deflected and the central portion of the upper end wall 33 carrying the same may be deflected with a considerably less force than was needed with the prior art devices to interengage the teeth.
  • a closure for fastening to containers comprising: an outer cap having a top end wall and skirt depending from an outer edge of said top end wall, an inner cap having a top end wall and a depending skirt joined to the outer edge of said end wall, said outer cap overlying said inner cap and being coaxial therewith, container fastening means on the skirt of the inner cap for releasably fastening on a portion of a container, radially and horizontally extending teeth on the upper surface of the top end wall of the inner cap extending in a first substantially horizontal plane, radially and horizontally extending teeth on the inner surface of the top end wall of the outer cap extending in a second substantially horizontal plane, vertically extending ratchet teeth on the inner wall of said outer cap skirt, vertically extending ratchet teeth in the outer wall of said inner cap skirt, said vertically extending ratchet teeth on said respective caps abutting when-the outer cap is turned in an application direction to rotate the two caps together and to cause said container fastening means to fast
