Definitions

  • the present invention relates generally to containers and, more particularly, to an improved container closure assembly and sealing arrangement therefor.
  • the invention is concerned with improved closure and sealing assemblies suitable for use in closing, in a fluid-tight manner, an orifice formed in a container of the type made of polyethylene or similar thermoplastic material.
  • a major problem heretofore encountered by manufacturers and users of containers suitable for transporting various commodities has been that of providing effective closure assemblies capable of closing discharge orifices or the like formed in such containers.
  • This problem has been a particularly troublesome one since often the users of such containers contemplate storing and transporting substances which are either contaminated by, or tend to destroy, conventional sealing gaskets, for example, gaskets made of rubber or the like.
  • a closure assembly wherein an effective fluid-tight seal is created simply by tightening down a closure element so that mating sealing surfaces respectively formed on the closure element and on the portion of the container defining the orifice are clamped together in a fluid-tight manner.
  • the seal comprises a plastic-to-plastic fluid-tight seal.
  • the container is intended to permit, on an optional basis, use of venting discs or reversible pouring spouts, it is desirable that the container neck or other orifice defining portion have a flat, substantially radial, planar top face adapted to intimately engage a corresponding fiat face formed on the closure element, for example, a closure cap or a closure plug.
  • the fact that the sealing surfaces of such closure elements are not always perfectly fiat has made it difiicult to form an effective, uniform fluid-tight seal.
  • the container neck or similar orifice defining portion is formed by molding plastic material, the stresses set up therein tend to introduce further irregularities which detract from the effectiveness of the seal.
  • sealing gaskets or washers made of resiliently deformable material, such as rubber provided a satisfactory solution to the problem, since the use of such material in containers which are .i,2d3 ,576 Patented Aug. 31, 1965 otherwise made entirely of polyethylene or similar synthetic thermoplastic material is generally undesirable and often limits the uses to which such containers can be put.
  • Another object of the invention is to provide a fluidtight closure assembly for a container wherein at least one of the components of .the closure assembly is shaped so as to define an integral resilient sealing surface made of the same material as the shaped closure component.
  • An ancillary object of the invention is to provide a novel fluid-tight closure assembly which, while not so limited in its application, will find especially advantageous use with containers made entirely of thermoplastic material, and wherein .an effective, fluid-tight, plastic-to-plastic seal is obtained without the need for machining to extremely close tolerances, yet which permits the use of a permanently resilient material, such as rubber, at points external to the seal, and thus out of contact with the container contents, for the purpose of preventing excessive deformation of the resilient plastic seal.
  • Yet another object of the invention is the provision of a novel fluid-tight thermoplastic closure assembly which permits of ease and economy in manufacture, and which may be readily assembled and disassembled.
  • FIGURE 1 is a fragmentary vertical cross-sectional view of a portion of a container and a closure assembly therefor embodying the features of the present invention, the closure assembly here shown as including a screw-cap;
  • FIG. 2 is a fragmentary vertical cross-sectional view of a modified form of closure assembly also embodying the features of the present invention, the closure here shown as including a reversible pouring spout and with the closure cap removed;
  • FIG. 3 is a view similar to FIG. 2, here illustrating the closure assembly with the closure cap applied;
  • FIGS. 4, 5 and 6 are fragmentary vertical cross-sectional views of other modified forms of closure assemblies also embodying the features of the present invention, the assemblies here including diverse types of closure plugs;
  • FIG. 7 is an enlarged fragmentary cross-sectional view of a closure assembly similar to that shown in FIG. 1, here employing a modified cap construction;
  • FIG. 8 is a view similar to FIG. 7 of yet another modified form of the invention.
  • a wall 11 made of polyethylene or similar thermoplastic material, which wall may be self supporting.
  • the wall 11 may also constitute an inner or a liner accommodated in an outer or overpack (not shown).
  • the container wall 11 is provided with an orifice 12 surrounded by an orifice defining portion in the form of a neck 14 having external screw threads 15 formed therein.
  • the exemplary closure assembly includes a closure element for the orifice which in the embodiment shown in FIG. 1, takes the form of a cap 16 provided with internal screw threads 18 of the same type and dimensions as the external screw threads on the neck 14, so as topermit the cap to be screwed onto the neck in order to close and seal the container orifice.
  • this is accomplished by forming a continuous circumferential groove 19 in the outer surface wall of the free extremity of the container neck 14, the groove defining an outwardly extending resilient sealing tongue 20 :having a flat planar face 21 adjacent to and engaging a sealing surface 22 of the screw cap 16.
  • the arrangement is such that the container neck 14 is formed with a substantially radial planar top face 21 mating with a substantially radial, planar face of the cap 16.
  • This particular shape of the neck 14 permits the optional use of a venting disc (not shown), an extensible spout (not shown), or a reversible spout of a type similar to that shown .in FIGS. 2 and 3.
  • the cross-sectional dimentions of the groove 19 are chosen such that the Wall thickness of the sealing tongue 20 and of the annular connection thereof with the body of the container neck 14 is relatively thin, thus rendering great flexibility to the sealing tongue. In this manner, substantial local deformations may be achieved which permit the sealing tongue 20 to conform with and adapt itself to any irregularities in or on the sealing surface 22 of the screw cap 16.
  • container closures employing relatively thin resilient sealing tongues 20 are characterized by their ability to conform to substantialiy any irregularities present in the mating sealing surfaces, it has also been found that the very flexibility of the tongue 20 can make it difiicult to obtain, under certain conditions, at specific pressure which is sufiiciently high to insure a fluid-tight seal.
  • the pressure may be increased by applying the closure element with a greater force-that is, in the exemplary closure 10 shown in FIG. 1, by'screwing the cap 16 more tightly home.
  • this might serve to ultimately close the circumferential groove 19 and therefore the advantages obtained by the provision of the groove might be destroyed.
  • a resilient supporting element 24 is positioned in the groove 19, the element serving to support the tongue 20.
  • the supporting element is in the form of a supporting ring 24 of resiliently deformable material which permanently retains its resiliency, such, for example, as rubber.
  • FIGURES 2 and 3 A slightly modified form of closure assembly, general y indicated at is shown in FIGURES 2 and 3 in the open and closed positions respectively.
  • the exemplary closure includes a reversible pouring spout 31 having a flange-like portion 32 resting on the top face of the container neck 14.
  • a groove 34 is formed in the flange 32 of the spout.
  • the upper portion of the flange 32 that is, the sealing tongue 20in its inoperative position (FIG. 2) is inclined with respect to the sealing surface 22 as contrasted to the radial surface defined by the tongue 20 in FIG. 1.
  • the arrangement is such that the inclined tongue 20' is deformed and stressed when the closure member, the cap 16', is applied (FIG. 3). It has been found that this shape of sealing tongue permits the elimination of a supporting ring under certain conditions.
  • the cap 16' is provided with an annular face depending from the top wall thereof and snugly fitting in the orifice defined, in this case, by the pouring spout 31.
  • This face is formed by the circumferential wall of an annular rib 35 on the inner surface of the top wall of the cap 16'.
  • FIG. 4 a slightly modified form of closure assembly is shown here including a closure plug 36 having a flange portion 38 and a shank portion 39.
  • the groove 19 is formed in the flange portion 38 so that the groove 19, and the supporting ring 24 (if provided as shown in the drawing), are well out of the way of the container contents.
  • FIG. 5 Still another exemplary form of the invention is shown in FIG. 5.
  • the closure element is in the form of a closure plug 40 having a shank 39.
  • the groove 19 is formed in the lowermost portion of the shank, thus preventing the groove 19 and supporting ring 24 (if present) from being soiled or damaged by weather conditions. Of course, they are also protected from other vunfavorable external conditions.
  • the container contents are prevented from coming into contact with the supporting ring, since the groove 19 is facing outwardly and the sealing tongue 20 therefore is also extending outwardly.
  • the closure element is also in the form of a closure p ug 41 having a flange portion 38' and a shank portion 39'.
  • the groove 19 is formed in the container neck 14 and, in order to protect the supporting ring 24 and the groove 19 from contamination by dirt, weather conditions or other causes, the plug 41 is formed with a circumferential skirt 42 depending from the periphery of the flange 38 and extending below the supporting ring 24.
  • FIG. 7 it will be observed that there is illustrated a closure assembly 10 very similar to the on shown in FIG. 1.
  • the cap 16' is provided with an annular ridge 44 on its sealing surface facing the sealing tongue 20 so that, in fact, the ridge forms the sealing surface. Because of the small area of the top or summit of the ridge 44, a relatively small force exerted on the closure member will be capable of generating a specific pressure which is sufficiently great to insure a fluid-tight seal.
  • the annular face of the cap snugly fitting in the orifice is constituted by the circumferential wall of a disc shaped projection 45 on the inner surface of the top wall of the cap 16'.
  • the annular face may be constituted by the circumferential wall of a recessed central portion 46 of the top wall of the cap, as indicated by the dotted lines in FIG. 7.
  • a supporting .ring 24 When, as shown in FIG. 7, a supporting .ring 24 is used with a cap having an annular ridge 44, it is important that the diameter D of the summit of the annular n'dge 24 is greater than the diameter d of the circle defined by the axis of the cross-section of the supporting ring. Otherwise, the supporting ring might locally or wholly be pressed outwardly, thus perhaps giving rise to difficulties and incorrect functioning.
  • the closure element or the orifice defining part are made of a thermoplastic material, one or both of these parts may include deviations from the cylindrical shape, or they may include inaccuracies in their dimensions. This may lead to the annular ridge 44 locally or wholly engaging the sealing tongue 20 inside of the supporting ring 24 instead of outside thereof.
  • the annular ridge may be provided on the surface of the sealing tongue 20 facing the sealing surface 22, as best indicated at 44' in FIG. 8.
  • a closure assembly for a container having an orifice surrounded by an orifice defining portion and a closure element for said orifice, wherein at least one of said portion and said element has a circumferential groove formed in its outer surface wall, said groove defining with said wall an annular, outwardly extending, at least slightly resilient tongue adapted to sealingly engage a surface on the cooperating part of the closure assembly, and a supporting ring formed of slightly resilient material positioned in said groove.
  • a closure plug for use with a container closure assembly said plug having a flange-like portion in the outer surface wall thereof and a circumferential groove formed in said flange-like portion, said groove defining with said wall an outwardly extending, at least slightly resilient, sealing tongue, and a supporting ring formed of at least slightly resilient material positioned in said groove.
  • a closure plug for use with a container closure assembly said ,plug having a circumferential groove formed in the outer surface wall of its lowermost portion, said groove defining with said wall an outwardly extending, at least slightly resilient, sealing tongue, and a supporting ring formed of at least slightly resilient material positioned in said groove.
  • closure assembly as set forth in claim 1, further characterized in that said closure element is a cap having an annular face depending from the top wall of the cap and snug-1y fitting in said orifice.
  • closure assembly as set forth in claim 1, further characterized in that said closure element is a plug having a circumferential depending skirt portion surrounding the groove formed in said orifice defining portion.
