Definitions
- An inner cap member is formed with a circular top panel having a depending skirt integrally molded therewith. The depending skirt is threaded on its interior surface for engagement with a conventional l Dec. 31, 1974 threaded'container finish.
- a ring wall projects vertically from the periphery of the top panel of the inner member.
- a plurality of spaced apart drive projections extend upwardly from the ring wall.
- Plural ratchet lug means also extend upwardly from the upper surface of the top panel.
- An outer member is likewise formed with a circular top panel and an integral depending skirt. integrally formed with the interior of the outer member top panel are a plurality of downwardly extending leaf spring members. A plurality of drive lugs extend downwardly from the periphery of the interior of the outer member top panel.
- the two members are assembled by pressing the inner member over a retention bead formed in the interior of the lower portion of the outer member depending skirt.
- the leaf spring members are inclined from a horizontal plane and will drivingly engage the ratchet lug means in the tightening direction to allow the assembled closure to be put on a container. However, the leaf spring members will slip over the lug means if one attempts to remove the closure, thus allowing the outer member to rotate freely with respect to the inner member.
- the outer member To remove the closure, the outer member must be pressed down to overcome the bias of the leaf spring members. This will bring the drive lugs of the outer member'into engagement with the spaces between the drive projections of the inner member, thereby allowing rotation of the inner and outer members in unison to allow removal of the closure.
- This invention generally relates to closures for containers. More specifically, this invention relates to a child-resistant safety closure. Most particularly, this invention relates to a child-resistant safety closure, having an improved type of removal drive, which may be applied with conventional capping machinery.
- the closure of the present invention is similar in concept to one disclosed in a co-pending application, U.S. Ser. No. 273,177, filed July 19, 1972 and having an assignee and one inventor in common with the present closure.
- the closure disclosed in the cited application has proven commercially workable.
- the present invention was developed to provide a better removal drive and to enhance the safety factor of the cited closure. Examples of the prior art may be seen in the following US. Pat. Nos. 2,964,207; 3,055,524; 3,692,199; and 3,705,662.
- This invention is a child-resistant closure for containers having an externally threaded finish portion.
- the closure includes the following components: (a) An inner cap member is formed having a top panel integrally formed with a depending skirt portion. The depending skirt portion has threads formed on its interior surface for engagement with the container finish portion. A vertically extending ring wall is integrally r formed with the periphery of the inner member top panel. A plurality of spaced-apart drive members extend upwardly from the ring wall; (b) An outer. cap member is formed with a top panel integrally formed with a depending skirt portion. The depending skirt portion of the outer member loosely encompasses the depending skirt of the inner member to allow relative rotary and axial movement between the inner and outer members.
- a plurality of downwardly directed drive lugs are integrally formed with the top panel of the outer member on the interior thereof.
- the drive lugs will engage the spaces between the drive members in one position of axial displacement of the inner and outer members and will be disengaged therefrom in a second axial position of the inner and outer members;
- Ratchet lug means are formed on'either the inner or the outer member and are interposed these two members;
- a plurality of inclined leaf spring members are formed on either the inner or the outer member and are interposed these two members. The leaf spring members provide a biasing force to maintain the inner and outer members normally in the second axial position.
- the leaf spring members will engage the ratchet lug means to drive the inner and outer members as a unit in the closure tightening direction, but will slip over the ratchet lug' means freely in the untightening direction to prevent unscrewing of the inner member from the container finish portion.
- Downward pressure on the outer member will overcome this bias of the leaf spring members to place the inner and outer members in the first axial position; and (e) A means is provided for loosely retaining the inner member within the outer member.
- FIG. 1 is a side elevational view, partially cut away, of the outer cap member of the present invention
- FIG. 2 is a perspective view, partially cut away, of the interior of the outer cap member of the present invention
- FIG. 3 is a perspective view of the upper portion of the inner cap member of the present invention.
- FIG. 4 is a perspective view of a slightly modified inner cap member as shown in FIG. 3;
- FIG. 5 is a side elevational view, partially cut away, of the inner member shown in FIG. 4;
- FIG. 6 is a side elevational view, partially cut away, of the assembled closure in engagement on a container in the configuration for application to a container;
- FIG. 7 is a view similar to FIG. 6 showing the inner and outer members engaged for rotation as a unit to allow removal from the container.
- the closure of the present invention is made up of two components: an outer cap member 10, shown in FIGS. 1 and 2, and an inner cap member 12, shown in FIG. 3, with modifications of this member 12 shown in FIGS. 4 and 5.
- the outer cap member 10 is formed with a circular top panel 14 integrally molded with a depending skirt portion 16. Molded into the underside of the top panel 14 and extending into the interior of the outer member 10 are a plurality ofleafspring members 18, 19,20 and 21, best seen in FIG. 2.
- the embodiment illustrated shows four leaf spring members 18,19, 20 and 21, but as few as two members will operate satisfactorily, and more than four members may be employed if desired.
- The'leaf spring members 18, 19, 20 and 21 take the form of inclined tabs integrally molded with the underside of the top panel 14.
- the leaf spring members 18, 19, 20 and 21 are inclined at an angle of about 45 with respect to the vertical axis of the outer member 10; however, the angle of inclination may be varied so long as a ratcheting function, to be described later, may be properly performed.
- the leaf spring members l8, 19, from the center of the top panel 1-4 which is less than the inside radius of the outer member 10.
- a plurality of drive lugs 24, 25, 26 and 27 are also molded into the underside .of the top panel 14 and depend downwardly.
- the drive lugs 24 through 27 are preferably located adjacent to the extreme outer portion of the inside diameter of the outer cap member 10 adjacent to the depending skirt 16. The drive lugs 24 through 27 then extend inwardly toward the leaf springs 18 through 21, but their edges terminate before reaching the leaf spring members 18 through 21.
- the illustration of four drive lugs 24 through 27 is simply by way of illustration and a single drive lug would function properly, but multiple drive lugs are preferred to allow a number of different removal engagement positions, as will be described later.
- a retention bead 28 is molded into the interior wall of the depending skirt 16 near the lower portion of the depending skirt 16. The retention bead 28 is continuous about the entire circumference of t:he'.depending skirt 16.
- the outer cap member 10 may be manufactured of any material sufficiently resilient to provide the neces- 20 and'21 are positioned on a radius lar top panel 30 and a depending skirt 32 attached thereto.
- the interior of the depending skirt 32 ay be provided with threads 34 for engagement with a threaded finish portion of a conventional container.
- Projecting vertically up from and integrally attached to the top panel 30 are a plurality of ratchet lug means.
- the ratchet lug means take the form of four ramp-type lugs 36, 37, 38 and 39.
- Each of the ramp lugs 36 through 39 has a substantially L-shaped configuration formed by an inclined ramp portion 40 joined to an axially extending vertical wall portion 42.
- FIG. 4 illustrates a modification ofthe ratchet lug means, in which the ratchet lug means comprises four elliptically shaped, vertically or axially extending ratchet lugs or raised bosses 36', 37', 38 and 39'.
- the ratchet function could be achieved by the use of a single elongated lug extending diametrically across the center of the top panel 30. Spaced between each of the ramp lugs 36 through 39 in FIG. 3 are teardrop shaped detent projections 44, 45, 46 and 47. These detent projections 44 through 47 project above the plane of the top panel 30 and, likewise, lie in the path of travel of the spring members 18 through 21. The precise functioning of these members will be explained later in detail. It may, likewise, be seen that the upper portion of the inner cap member 12 is ofa general configuration that may be considered to be castellated. That is, a ring wall 48 rises above the plane of the top panel 30.
- a retention bead 54 is molded into the exterior surface of the depending skirt 32.
- the retention bead 54 extends about the entire circumference of the depending skirt 32 and is of a diameter greater than that of the retention bead 28 formed in the depending skirt 16 of the outer cap member 10.
- the depending skirt portion 32 may terminate in an inwardly depending tapered sleeve 56 which has formed therein a number of grooves 57. This particular feature is strictly for convenience in manufacture and allows removal of the inner cap member 12 from a mold with greater facility,
- the modified form of the inner cap member 12, designated in FIG. 4 as 12, retains substantially most of the features described with resepct to the inner cap member 12. In fact, these two members 12 and 12 are interchangeable with the outer cap member 12.
- the ratchet lug means in FIG. 4 are in the form of the elongated elliptical lugs 36 through 39'.
- ratchet lugs 36 through 39' two radially separated arcuate lands extend bevtween adjacent ratchet lugs 36 through 39'. These lands 58 and 59, are used primarily to bias the spring -members 18 through 21 into a particular desired degree of downward force and to hold their position accurately. This enhances the safety feature of the assembled closure in eliminating any possibility of accidental engagement of the drive mechanism. It should be realized that the elliptical ratchet lugs 36' through 39 could be used with the detent projections 49 through 51, and conversely, the ramp lugs 36 through 39 could be used with the arcuate lands 58 and 59. The precise configuration which will be chosen depends upon the specific design problems involved, but is a matter that should be readily soluble by one skilled in the art.
- the inner cap member 12 is an independent closure-in itself for a container.
- the inner member 12 therefore may be made of any suitable material and need not necessarily be made of the same material as that of the outer cap member 10; however, it has been found that a thermoplastic material such as polyethylene or polypropylene is particularly well adapted for the manufacture of the inner cap member 12.
- the completed safety closure of the present invention is shown partially cutaway.
- the safety closure is formed by assembling the outer cap member 10 and the inner cap member 12.
- the retention bead 28 is forced over the retention bead 54, in the process causing the depending skirt 16 of the outer closure cap member 10 to spring outwardly slightly.
- the depending skirt springs back inwardly trapping the inner cap member 12 within the outer cap member 10.
- the fit between the outer member 10 and the inner member 12 is not tight. There is an appreciable gap between the interior of the depending skirt 16 and the exterior of the depending skirt 32.
- the outer cap member 10 may both rotate and axially slide with respect to the inner cap member 12.
- the inner cap member 12 is threadably engaged on the exteriorly threaded finish portion 60 of a container 61.
- a sealing disk 62 is trapped between the upper portion of the finish 60 and the lower portion of the top panel 30 of the inner member 12.
- the leaf spring member 18 may be seen to be in driving engagement with the lug 37.
- the other leaf spring members 19, 20 and 21 are in driving engagement with the other ratchet lug members 36', 38 and 39'.
- the arcuate lands 58 and 59 of the inner closure member 12' are seen to be touching the leaf spring members 18 through 21, thus holding the leaf spring members 18 through 21 in a preferred biasing position, providing a known spring force to keep the inner member 12 separated from the outer member 10.
- the embodiment designated as 12 in FIG. 3 is not shown, it should be obvious to one skilled in the art that the ratchet function just described would also take place if this particular embodiment were used.
- the leaf spring members 18 through 21 would wedge or drivingly engage the vertical wall portions 42 of the ramp lugs 36 through 39.
- the combined closure could be tightened or screwed onto the threaded finish 60 without any further manipulation.
- the leaf springs 18 through 21 would rise up the ramp portions 40 of the ramp lugs 36 through 39 and would not impart sufficient loosening torque to the inner cap member 12;
- the detent projections 44 through 47 act as a further safety feature in the embodiment shown in FIG. 3. If the outer cap member 10 is turned in a direction which would normally unscrew the combined closure from the finish 60, once the leaf springs 18 through 21 have risen completely up the ramp portion 40 of the ramp lugs 36 through 39 and fallen off the opposite side, the detent projections 44 through 47 will tend to hold the leaf springs 18 through 21 in that position.
- the detent projections 44 through 47 are positioned such that the drive lugs 24 through 27 are aligned with the drive projections 49 through 52 when the leaf springs 18 through 21 are stopped by the detent projections 44 through 47. This position helps prevent overstressing of the leaf springs 18 through 21 when the closure is subjected to a vertical load, as in a warehouse.
- the drive lugs 24 through 27 are in contact with the drive projections 49 through 52 to prevent this overstressing.
- FIG. 7 may be considered one position of axial displacement of the outer member 10 and the inner member 12', while the configuration of FIG. 6 may be considered a second position of axial displacement of the outer member 10 and the inner member 12'.
- the leaf spring members 18 through 21 serve to normally keep the outer member 10 and the inner member 12 in their relationship shown in FIG. 6, in which configuration removal of the closure from the container is impossible.
- the outer cap 'member 10 may be pressed downwardly over the inner cap member 12.
- the downward-displacement of the outer capmember 10 brings the drive lugs 24 through 27 into engagement with the spaces between the drive projections 49 through 52. It should be realized that the alignment of the drive lugs 24 through 27 and the spaces between the drive projections 49 through 52 may not be perfect at the time the outer cap member 10 is pressed downwardly. However, slight rotation of the outer cap member 10 in the loosening direction will bring these members into proper drive engagement. With the drive lugs 24 through 27 properly engaged, the outer cap member 10 may be rotated and the inner cap member 12 will rotate with it as a unit through this driving engagement. Once the combinedclosure is removed from the container and the downward pressure on the outer cap member 10 is released, the combined closure will spring back the configuration shown in FIG.
- the combined closure of this invention assembled from the outer member 10 andthe inner member 12 or 12' may be applied by conventional capping machinery, since there is no need for any manipulation of the closure during the tightening procedure. That is, the combined closure may always be put onto the finish of a container 61 without any extra manipulation of the combined closure, a departure from the requirements of most child-resistant closures of the prior art.-However, removal of the closure requires manipulation which has been found to be beyond the abilities of most children.
- a child-resistant closure for containers having an exteriorly threaded finish portion comprising, in combination: an inner cap member having a top panel integrally formed with a depending skirt portion, said depending skirt portion having threads formed on the interior surface thereof for engagement with said finish portion of said container, an axially extending ring wall integrally formed with the periphery of said inner member top panel, a plurality of spaced apart drive members formed in the outer extremity of said ring wall; an outer cap member having a top panel integrally formed with a depending skirt portion, said depending skirt portion of said outer member loosely encompassing said depending skirt portion of said inner cap member to allow relative rotary and axial movement between said inner and outer members, a plurality of downwardly directed drive lugs integrally formed on the interior of the top panel of said outer member, said drive lugs engaging the spaces between said drive members in one position of axial displacement of said inner and outer members and being disengaged therefrom in a second axial position of said inner and outer members;
- ratchet lug means formed on one of said innerand outer members and interposed said members; a plurality of inclined leaf spring members, formed on one of said inner and outer members and interposed said members, said leaf spring members providing a biasing force to maintain said inner and outer members in said second axial position and to drivingly engage said ratchet lug means in said second axial position to drive said inner and outer members as a unit in the tightening direction of said closure but slip over said ratchet lug means freely in the untightening direction to prevent unscrewing of said inner member, downward pressure on said outer member overcoming the bias of said leaf spring members to place said inner and outer members in said first axial position; and means for loosely retaining said inner member within said outer member.
- said ratchet lug means comprises at least two inclined ramp ratchet lugs integrally molded on the exterior of said inner member top panel, each of said inclined lugs including, a ramp portion inclined upwardly in the direction in which said inner member would be moved for removal from said container finish, and an axially extending wall portion joined to the upper terminus of said ramp portion.
- closure of claim 5 further including detent projections; formed onthe exterior of said inner member top panel, positioned between said inclined ramp lugs for interference with said leaf spring members in the untightening direction of said closure.
- closure of claim 5 further including at least one arcuate land extending between each of said inclined ramp lugs, said leaf spring members normally being biased .by contact with said arcuate lands.
- leaf spring members comprise at least two downwardly extending flexible tabs integrally molded on the interior of said top panel of said outer cap member.
