Definitions
- a safety cap of resilient plastic material having a depending skirt within which is formed an annular rib having an anchor portion and a radially inwardly projecting locking lug diametrically opposed to such anchor portion, the rib and the locking portion being of substantial radial extent for positive engagement beneath the locking rib around the container neck to strongly resist removal of the cap.
- the remainder of the annular rib within the cap skirt is of reduced radial width to function in the manner of a snap rib on the lug side of the skirt.
- the skirt rib has a continuous annular upwardly presented cam surface for cooperation with the locking rib of the container neck to maintain the end wall of the cap in sealing engagement with the end of the neck. Rotation of the cap to bring the lug into registry with the cap through the locking rib of the container neck permits upward flexing of the lug side of the closure cap and free movement of the lug through the gap, the portions of the skirt rib on either circumferential side of the lug being of sufficiently reduced radial dimension to snap upwardly past the locking lug of the container and during continued removal of the cap to function as pilots for leading the opposite ends of the anchor portion of the container rib upwardly past the locking rib until the cap is removed.
- This invention relates to a new and improved safety closure cap which is particularly adapted for use on containers for pills and other medicines in a manner such as to prevent removal by children.
- the present invention is an improvement over safety caps of the type exemplified in the Grimm US. Pat No. 3,393,8l6 of July 23, 1968, in which the cap is of a generally resilient plastic material, having locking means or projections extend ing inwardly from its skirt for locking disposition beneath the cooperating rib or bead around the neck of the container.
- the cap skirt with an inwardly projecting lug diametrically opposed to an inwardly projecting arcuate rib segment, in such manner that when the cap is operatively applied to the container, the lug and rib segment are disposed just beneath and in positive abutting engagement with the lower face of the locking rib around the container neck to positively resist removal, though the cap is rotatable on the container neck to bring the lug into registry with a gap through the locking rib of the neck, whereby the side of the cap bearing such lug may be flexed and tilted by thumb pressure to move the lug upwardly through the gap and thus remove the cap.
- the containers employed with such prior closure caps included abutment means engaging in the lower end ofthe cap skirt to limit movement of the cap unto the container neck and thereby to restrict any sealing engagement of the cap with the end of the container neck.
- the primary objects of the present invention are to provide a snap-on-type safety closure cap for the container which is urged and maintained in sealing engagement with the end of the container neck at all times around the full periphery thereof, regardless of the rotary or angular orientation of the closure cap on the container.
- closure cap which may be readily snap fitted onto the container in the manner of a conventional snap cap; to provide such a cap in which the snap-fit retention means interengage throughout the angular extent of the locking rib around the container neck and in all positions of angular orientation of the closure on the container neck; and to provide such a safety closure cap which, when rotated to proper position on the container neck, may readily be removed merely by moderate finger pressure and thus is particularly adapted for use by an arthritic or inform person. Also, it is an object to provide such a closure cap which may be properly angularly rotated or oriented to removal position by a blind person merely through sense of touch or feel.
- the radial width of the inwardly projecting skirt lug and of an arcuate portion of the skirt rib diametrically opposed to such lug are sufficient to firmly engage beneath the locking rib of the container neck to positively resist removal of the cap. However, to permit removal of the cap. However, to permit removal when the plug is positioned by rotation of the cap in registry with the gap through the neck-locking rib, the
- radial width of the neck bead on opposite circumferential sides of the lug is sufficiently reduced as to afford merely a yielding holding engagement with the locking rib of the neck to permit upward tilting and removal of the cap.
- FIG. ll is an exploded perspective view of a closure cap in accordance with the invention, together with the upper por tion of a container to which it is to be applied.
- FIG. 2 is an enlarged bottom plan view of the closure cap.
- FIG. 3 is a diametrical cross section through the closure cap taken on the line 3-3 of FIG. 2;
- FIGS. 4, 5 and 6, respectively, are fragmentary cross sections through the container cap taken respectively on the lines 41-41, and 6-45 of FIG. 2.
- the numeral therein designates a container body which may be formed of a conventional glass or plastic material having a neck 12 of circular cross section which defines an access opening M into the container.
- a container body which may be formed of a conventional glass or plastic material having a neck 12 of circular cross section which defines an access opening M into the container.
- an annular locking rib 116 of constant radial dimension having an upwardly presented and upwardly convergent cam surface 116' thereon and abruptly downwardly directed lower annular face 116" which in the present embodiment is in substantially a radial plane: for positive holding engagement with the cooperating portion of the closure cap as hereinafter described.
- the locking rib 116 is not completely annular, but is formed with a small gap 18 therethrough.
- the closure cap 20 of the invention when applied to the neck 112 is rotatable thereon about the axis of the neck.
- the cap has a top or end wall 22 extending over the end of the neck and a depending cylindrical skirt 241 which encircles the neck.
- a locking lug 26 projects radially inwardly from one side of the skirt for locking reception beneath the locking rib 116 of the container neck, though rotation of the cap may so angularly orient it as to bring its lug into registry with the gap 18 through the locking rib, the lug being proportioned for free movement vertically through the gap 118 to permit removal of the cap.
- the cap skirt has a radially inwardly projecting annular rib 28 integral therewith around its inner periphery in the same radial plane as the lug 26 and in spaced relation from the end wall 22, such that when the cap is operatively applied to the container, the ribs 16 and 28 cooperate to press the end wall 22 into sealing engagement with the annular upper end of the container neck.
- the cap will be formed of a suitable plastic or other material having sufficient elastic resiliency that its skirt 24 and internal rib 2d are elastically expansible for snap fitting of the rib downwardly over the locking rib 16 of the container neck as the cap is pressed downwardly over the container neck during application. Thereafter, the expanded skirt and its rib 28 will resiliently contract beneath the locking rib 16.
- the ribs 16 and 28 of the neck and closure cap have coacting cam means exemplified by the upwardly directed and upwardly converging cam surface 16' of the neck locking rib 16, in conjunction with the inner periphery of the cap rib 28.
- the cooperating ribs are provided with further cam means exemplified here by the upwardly directed and upwardly diverging cam surface 28 at the upper edge of the bead or rib 28, the cam surface 28' being 360 in extent in the preferred embodiment so as to coact with the outer periphery of the locking rib l6 throughout the entire angular extent of the latter, in any rotational position of the closure cap.
- the radial width of the skirt rib 28 is not constant. Rather it is an important feature of the invention that this rib varies in width at different angular locations therearound.
- the skirt rib 28 includes an anchor portion 28A having its circumferential midsection diametrically opposed to the retainer or locking lug 16.
- the anchor portion 28A and the retainer lug are of sufficient radial width, and thus in each instance project a sufficient distance beneath the locking rib 16 of the container neck to offer a strong positive resistance to upward displacement of the closure cap by manual pressure at any point around the circumference of the skirt.
- these parts may be and, in accordance with the preferred embodiment of the invention, are of sufficient radial width as to render impossible the removal of the cap by the mere exertion offinger pressure either by a child or by most adults.
- the variations in width of the rib 28 are arranged symmetrically to a diametrical line passing through the lug 26 andbisecting the arcuate anchor portion 28A, this being the line 3-3 of FIG. 1.
- the anchor portion 28A extends for substantially half the circumference of the cap and at its opposite ends merges smoothly with the relatively reduced radial width releasing portions 23B--28B, the ends of which preferably are located about 90 apart and symmetrically to the lug 26. Extending between and merging smoothly with these ends is a still further reduced radial width releasing portion 28C which extends continuously form the end of one portion 28D to the other.
- skirt rib portions jointly define a complete annular rib 28 having an upwardly diverging camming and holding surface 28', the entire circumference of which is adapted for operative engagement with the downwardly directed face of surface 16" (except at the gap 18), for firmly securing the cap on the container with the top wall 22 of the cap urged into firm sealing engagement with the upper end of the container neck around the entire periphery of the latter.
- the arrangement is such as to permit this effect despite the interruption in the holding effect caused by the gap 18, because the gap is normally of insufficient angular extent to disrupt this 360 sealing effect.
- the latter is provided with a radially outwardly directed thumb tab 30 which projects outwardly in radial alignment with the locking lug 26.
- this tab 30 there may be associated a vertical reenforcing and stiffening web 32 serving as a pointer in cooperation with the apex of the triangle 34 or other indicia on the container neck to indicate when the lug 26 is accurately in registry with the gap 18 so that the cap is thus properly oriented for removal from the container.
- indicia 32 and 34 and the use thereof are by no means essential to successful operation of the invention, inasmuch as the arrangement of the closure cap in conjunction with the container is such as to facilitate the sensing of its arrival at removal position simply by feel. That is, when the cap is rotated to bring its lug 26 into registry with the gap 18, the fact of its disengagement form the undersurface 16" of the locking rib can be detected by feel, thus adapting the closure cap and container of the invention for use by persons with impaired vision.
- the cap will normally be applied to the container with the rib 28 thereof projecting beneath and interengaged with the container rib 16, the cap normally being in a position of angular orientation of the container such that the lug 26 is out of registry with the gap 18. In this position, the lug 26 as well as the diametrically opposed anchor portion 28A of the rib 28 will be in positive container so'that manual removal of the cap in such applied condition is very strongly resisted and for all practical purposes is impossible of achievement by a child.
- the cap In order to remove the cap, it may be rotated to its removal position indicated in FIG. 1, in which the lug 26 registers with the gap 18. Such position may be determined either by sense of touch or by means of the indicia 32 and 34. With the cap thus oriented, it is then necessary to apply but a moderate amount of upward finger pressure on the thumb tab 30, to urge the lug 26 upwardly through the gap 18.
- the portion 28C guides the symmetrically disposed rib portions 28B upwardly past the locking rib 16.
- the cap In order to reapply the cap to the container, it may merely be seated on the container in any angular position of orientation and pressed axially downwardly, in which event the camming engagement of the upper cam surface 16' of the container locking rib will exert a spreading and expanding force causing the resilient skirt and its associated rib 28 and lug 26 to spread outwardly and then snap beneath the lug 16.
- the releasing portions or segments 28B and 28C of the rib 28 be of constant width and in stepped relation, as in the preferred embodiment, as they may for instance, be of gradually diminishing or tapered width from the ends of the anchor segment 28A to the lug 26.
- a container body having a neck of circular cross section defining an access opening through its upper end, an annular locking rib of constant radial dimensions encircling said neck and formed with a vertical gap therethrough, a closure cap disposed for rotary movement on said neck, said cap having an end wall extending over the end of said neck and having a depending skirt encircling said neck; a locking lug projecting radially inwardly from said skirt beneath said locking rib and rotatable with the cap into angular registry with said gap, said lug being proportioned for free movement through said gap; a radially inwardly projecting annular rib integral with said skirt around the inner periphery thereof in spaced relation from said end wall, said wall, said skirt rib being in a common radial plane of the skirt with said locking lug; said skirt and its rib being elastically expansible for snap fitting of its rib downwardly over the said locking rib as the cap is pressed downwardly over the container neck, to thereafter resiliently contact beneath said locking rib,
- said anchor portion of the skirt rib is of uniform cross-sectional dimension throughout its angular extend and said releasing portion comprises several stepped segments, each of uniform cross section throughout its length, with such segments being arranged in symmetrical pairs on opposite circumferential sides of said locking lug and progressively decreasing in radial width from the anchor portion toward said lug, said segments being integrally interconnected and each such segment merging smoothly with adjoining portions of the rib for riding smoothly over the locking rib of the container neck during removal of the closure cap.
- a closure cap for a container comprising a circular end wall for disposition over the neck of the container and a depending cylindrical skirt for telescoping reception of the container neck, a locking lug projecting radially inwardly from said skirt, and a finger tab projecting radially outwardly from said skirt in alignment with the locking lug, a radially inwardly projecting annular rib integral with said skin around the inner periphery thereof in spaced relation to said end wall and in common radial plan of the skirt with said skirt around locking lug, said skirt and its rib being elastically expansible for snap fitting of the rib downwardly over a cooperating rib of the container neck, said skirt rib having an upwardly presented upwardly diverging cam surface for cooperation with the container neck rib to cam the end wall of the cap downwardly into sealing engagement with the end of the container neck, said skirt rib comprising interconnected arcuate portions of varying radial width, including an anchor portion having its midsection diametrically opposed to said retainer lug an the ends of said anchor portion
