Definitions

  • ABSTRACT A leak-proof closure for a liquid container having a threaded neck.
  • a cap for the closure has internal threads which mate with those on the container neck.
  • the cap has an annular skirt portion above or below the threaded section.
  • the container neck has at least one annular sealing ring on its outer surface at such a level that the cap skirt portion fits circumjacent the ring when the cap is threaded onto the neck into closed position.
  • the outer diameter of the ring and the inner diameter of the cap skirt are such that an interference fit therebetween is established.
  • the sealing ring or rings have a sharp edge in order to provide substantially a line contact with the skirt portion.
  • the liner In a threaded container, if the liner takes a set, the cap must be turned on to the container a greater distance with each successive removal and replacement in order to seal the container. In a bayonet type the liner may gradually be compressed beyond sealing thickness and, of course, cannot be sealed against leakage. if it has taken .a set.
  • the cap from thevcontainer; the cap and the container neck having cooperating means which maintain the closure in leak-proof condition even though it may be retracted slightly from its initial closed position.
  • FIG. 1 is a fragmentary, diametric, vertical, sectional view of a closure embodying the invention'as utilized on a child-proof closure-embodying Gach and Leonard Application, Ser. No. 278,l01, filed Aug. 4, 1972 now US Pat. No. 3,770,153;
  • FIG. 2 is a horizontal, partly plan and partly sectional view, taken along the line 2-2 of FIG. 1;
  • FIG. 3 is a horizontal sectional view taken along the line 3-3 of FIG. 1;
  • FIG. 4 is a vertical, diametric, sectional view of a cap according to the invention.
  • FIG. 5 is a fragmentary view in side elevation of a closure embodying the invention, the interior parts being shown in phantom;
  • FIG. 6 is a fragmentary, isometric view of a container neck embodying the invention as provided with means cooperating with the cap shown in FIG. 4 to render'the closure leak-proof;
  • FIG. 7 is a fragmentary, vertical sectional view of a modified form of closureembodying the invention.
  • FIG.- 8 is a view similar to FIG. 6 but of the neck of the container also shown in FIG. 7;
  • FIG. 9 is a view similar to FIG. 7 but showing a third modification of'the'inven'tion
  • FIG. 10 is a view similar to FIG. 8 but of the neck of the, container also shown in' FIG. 9;
  • FIG. 11 is a view similar to FIGS. 7 and 9 and showing yet another modification of the invention.
  • a closure embodying the invention is designed for a container, generally indicated by the reference number 10, having a neck 11 to be closed by an inverted cupshaped cap 12.
  • the container neck 11 and the cap 12 have cooperating disengageable means for retaining the cap 12 on the container 10 which consist of external threads 13 on the container neck 11 and internal threads 14 on the inner side of a cap skirt l5.
  • the cap 12 also has an interior liner 16 which is squeezed tightly against the end of the neck 11 when the cap 12 is on the container in closed position as illustrated in FIG. 1.
  • the cap 12 has a depending skirt portion 17 which extends downwardly beyond its threads 14 and fits closely circumjacent to one or more sealing rings 18 provided on the exterior of the container neck 11 at a level below its threads 13.
  • the outer diameter of the sealing rings 18 and the inner diameter of the cap skirt which in this case, is substantially a line contact between the sealing ring or rings 18 and the skirt portion 17, much in the fashion of a O-ring.
  • the sealing rings 18 have sharp edges so as to maintain the line'contact. 1
  • the advantage accruing from the cooperating ring and annular skirt portion according to the invention also is important upon initial capping of the container on the production line of the establishment at which liquid containers are filled.
  • each degree of rotation of the six pitch thread results in 0.0005 inch vertical movement, thus, 40 below nominal results in the liner being compressed0020 inch beyond (thinner) than nominal or, on the other hand, results in the liner only barely contacting the bottle neck or not contacting it at all.
  • a closure of this type comprises a pair of depending locking lugs 19 on an outer cap skirt 20 which are engage able in two square ended recesses 21 formed in a shoulder 22 on the container 10.
  • the locking lugs 19 engage cams 23 on the shoulder 22' of the container and are urged outwardly as the cap 12 is rotated to closed position, finally snapping into the recesses 21.
  • the cap structure according to the mentioned Gach and Leonard application has been proven to be substantially child-proof. However, if the cap is screwed onto the container to a degree such that the locking lugs move any distance beyond the square shoulders of the cooperating recesses 21, the cap liner 16 may be compressed to a degree such that it will not restore to its original thickness.
  • FIGS. 7 and 8 illustrate how a closure embodying the invention may be arranged so that one or more sealing rings 25 are located at the upper end of a container neck 26 for cooperation with an annular skirtportion the cap 28, are illustrated in FIGS. 7and 8 as being the same type as that shown in FIGS. 1-6, inclusive, with respect to the child-proof design of the cap,these features of child-proof construction are the subject matter of the mentioned Gach and Leonard application and are not the basic subject matter of the instant application. The combination of such child-proof features with the leak-proof features of the instant invention, however, does constitute an improvement over the mentioned Gach and Leonard application.
  • FIGS. 9 and 10 A third embodiment of the invention is illustrated in FIGS. 9 and 10 where a single sealing ring 30 is formed on a neck 3l of a bottle 32, or other container, at a level below the cap retaining means, i.e. bottle neck threads 33.
  • a cap 34 as shown in FIG. 9 has an annular skirt portion 35 below its internal threads 36. The annular skirt-portion 35 and the flat,
  • a bottle or other container 37 has a neck 38 provided on its outer surface with a plurality of undercut recesses 39 and axially extending slots 40. In this embodiment, four of the slots 40 and the recesses 39 are shown. At a level just below the bottoms of the recesses 39, one or more sealing rings 41 are also formed on the exterior of the bottle neck 38. These rings may be substantially identical with the rings 18 of FIGS. 1-6, or the rings 25 of FIGS. 7 and 8. Similarly, of course, and if desired, instead of a plurality of rings 41 as shown in FIG. 11, a single cylindrical ring such as the ring 30 of FIG. 10 may be employed with a bayonettype closure as shown in FIG. 11.
  • a cap 42 has a plurality of inwardly extending lugs 43 which are of such size and so positioned as to be movable downwardly through the slots 40 and, when the cap 42 is rotated in a clockwise direction, to enter the recesses 39 to retain the cap 42 on the bottle 37.
  • the sealing rings 41 engage the inner surface of an annular skirt portion 44 of the cap 42.
  • FIG. 11 also shows how the child-proof feature of the mentioned Gach and Leonard application may be employed on a bayonet-type cap embodying the instant invention.
  • the sealing ring provided by the instant invention substantially eliminates this problem.
  • the interference fit between the sealing ring or rings and the annular cap skirt portion provides enough frictional resistance to prevent the backing off or unscrewing which might otherwise result.
  • the sealing ring and cooperating annular cap portion of the invention overcomes an additional problem often encountered.
  • filled containers having either threaded or bayonet type caps are stacked in warehouses or during shipping, especially those containing heavy liquids, the caps are pressed down tightly against the liners to the full extent of any tolerance or possible vertical movement. This gives the liners the undesirable set so that when the top pressure is removed, leakage may result. Because the horizontal seal provided according to the invention is not affected by such vertical pressure, the resistance to cap removal and secondary seal against leakage of a closure according to the invention remain effective.
  • a leak proof safety closure comprising a container and a cap, and said container having a bottom, a sidewall, a neck and an annular shoulder extending between said neck and said sidewall, and at least one lug recess in said container adjacent the periphery of said shoulder, said cap having a top, an inner wall depending from said top, cooperating means on said closure neck and said inner wall for retaining said cap in closed position on said container, at least one annular sealing ring on said container neck, said sealing ring having an outer diameter fitting tightly within said inner cap wall when said cap is in closed position, and an outer skirt depending from said top in concentric relationship to said inner wall, said skirt including at least one depending lug having a lower portion extending below the bottom of said inner wall and engageable in said lug recess.
  • a closure according to claim 1 and a resilient liner in the cap that is engageable with the end of the container neck when said cap is in closed position.
  • the improvement comprising a circumferentially extending series of lug recesses in the container-shoulder which are sequentially engaged by the locking lug when the cap is screwed more tightly onto the container neck.
  • a closure according to claim .1 in which there are a plurality of spaced annular sealing rings on said container neck.
  • annular sealing ring has a sharp outer edge for establishing substantially a line contact with the inner surface of said cap skirt.
  • a leak proof safety closure comprising a container and a cap, said container having a bottom, a sidewall, a neck and an annular shoulder extending be-- tween said neck and said sidewall, at least one lug recess in said container adjacent the periphery of said shoulder, said cap having a top, a wall depending from said top, cooperating means on said closure neck and said wall for retaining said cap in' closed position on said container, and at least one integral annular sealing ring between said wall and said containerv neck, said sealing ring having an interference sealing fit when said cap is in its closed position, said wall depending from said top and including at least one lug adjacent its lower edge engageable in said lug recess.
