1'? Claims. (Cl. 222-520) :Ihis invention relates to improvements in, portable container closures and particularly to an improved dispensing closure for a container such as a bottle, jar, can or carton.

While various forms of dispensing closures for portable containers have been previous'lyprovided they have not proved to be entirely "satisfactory under service conditions for which the device'of the invention has been particularly designed. Such previously proposed devices have not always definitely precluded leakage of the container contents nor sufficiently sealed such contents against evaporation and exposure to the air, permitting loss or deterioration of such contents by evaporation, oxidation, and wetting by atmospheric moisture. In many cases the parts of such closures are separable Irom the container and thus subject to loss, and are difficult to manipulate to open and close the container.

It is among the objects of the present invention to provide an improved portable container closure that may be easily manipulated between its open and closed positions, that may be ad.- justed to various intermediate positions to control the rate of dispensing the container contents, that provides a fluid tight seal'for the container when closed and is so constructedas to preclude leakage between the container and the closure device.

A further object resides in the provision of a portable container closure, all parts of which are permanently secured to the container to avoid inisplacement and loss of the closure parts. I

A still further object resides in the provision of an improved portable container closure that is attractive in appearance, simple and'ec'onomical to manufacture, easy to operate andwhich may be operated repeatedly without damage or deterioration so that the container contents may be dispensed a small quantity at a time over a long period.

Other objects and advantages-will becomeapparent from a consideration of the ,iollowingldescription in conjunction with the accompanying drawings, in which:

Fig. 12, a. longitudinal sectional view of a freementary portion of a container and a closure similar to the closure illustrated in Figs. 9, l0 and 11 but omitting certain elements of the rare viously illustrated closures for the purpose of simplifying the closure construction;

With continued reference to the drawings and particularly to Fig. 1, the container, generally indicatedat I0, is illustrated as a glass jar or bottle of substantially cylindrical shape having a side wall II from the upper edge of which extends an inwardly directed top Wall portion 12 from which a hollow cylindrical neck I3 extends upwardly. At its upper end the neck l 3 is necked in, as indicated at I 4, and provided with a central opening or aperture 15 through which the contents of .the container l0 may he discharged. Externally the neck I3 is provided with a screw thread .16 adjacent the lower end of which there is provided an outwardly extending integral annular flange H.

A generally cylindrical closure cap, generally indicated at I8, is provided with internal screw threads which engage with the screw thread l6 on the exterior of the container neck I 3. At its bottom or lower end the cap I8 is provided with an outwardly extending annular flange l9 and at its opposite end is necked in, as indicated at 20, to a discharge opening 2| surrounded by an annular lip 22.

As illustrated,'the container I isformedof glass or other ceramic material and the cap I8 is formed of a synethtic resin or plastic. Other materials may be used, however, for both the container and the cap without in any way exceeding the scope of the invention. For example, Fig. 2 illustrates an arrangement in which the container is formed of glass or ceramic material and the cap is formed of thin metal, both the cap and the container could be formed of metal or both could be formed of synthetic resin, as indicated in Fig. 4. The invention is in no way limited to any specific material for either the container or the cap but it is preferred that the cap at least be made of some readily moldable or formable material such as synthetic resin or relatively soft thin metal.

The exterior of the cap I8 is preferably fluted or. otherwise provided with an ornamental surface which is not completely smooth in order to provide a better hand grip for turning the cap on the screw threaded neck I3.

A solid ring or washer 23 rests upon the external surface of the necked in portion of the container neck [3, this surface providing an annular shoulder contacting the adjacent surface of the washer. The inner annular surface of the washer is in contact with the external surface of the lip 24, which extends upwardly from the necked in portion Hi and the external annular surface of the washer is in contact with the inner surface of the cap IS. The washer or gasket 23 thus provides a fluid tight seal between the outer portion of the container neck l3 and the outer portion of the cap 18 so that fluid cannot leak into the space between the container neck and the cap and flow backwardly through the screw container neck l3 and the seal 21 is pressed firmly against the outer end of the container neck surrounding the aperture l5. This provides a fluid tight seal for the container. The washer 23 is formed ofv a firm material, such as hard rubber, and is fixed in the cap 18 in position to hold the outer edge portion of the supporting disk 26 firmly against the internal cap shoulder 25.

a When the cap is turned outwardly on the container neck the washer 23 moves outwardly on the reduced outer end portion of the container neck and the cap and washer will carry the supporting disk 26 and seal 21 away from the end of the container neck so that container contents may pass under the seal, through the apertures in the supporting disk and through the aperture in the cap when the container is inverted. The washer forms a ring about the reduced outer end portion of the container neck so that when the container is uprighted and portion of the content in the space between the container neck and the outer end of the cap will be returned into the container.

The cap 18 is retained in permanent assembly with the container by suitable means such as the metal band of generally channel shaped cross section, generally indicated at 30. This band has an inwardly extending annular flange 3| overlying the flange IQ of the cap and an inwardly directing bead or rolled portion 32 at its end opposite the flange 3|, the edge of which bead is engageable with the under surface of the container flange I! so that the cap l8 cannot be separated from the container but can be loosened only an amount sufflcient to properly space the seal 21 from the end of the container neck to permit dispensing of the container contents threads and out of the space between the flanges H and 19 to the exterior of the container. This prevents wetting of the users hands by liquid contents of the container and also prevents fouling or corroding of the screw threads, which condition would render, it diflicult to turn the cap on the container neck.

At the necked-in portion 20 the cap I8 is provided with an internal annular shoulder 25 which seats upon the outer edge portion of a disc 26 having a diameter substantially the same as the internal diameter of the cap. This member 26 carries a disc-shaped seal 21 preferably formed of resilient material such as rubber, cork, pap-er, etc., and surrounding the seal 21 a. series of apertures 28 is provided in the disc 26.

The construction of the disc 26 and seal 21 is particularly illustrated in Fig. 6 wherein the seal is shown positioned substantially concentrically of the supporting disc and held in operative position against the surface ofthe supporting disc by bent over metal tongues 29 which are struck up from the disc at the time the apertures 28 are provided. These tongues are bent over the edgeportion'of the seal 21 and retain the seal firmly in position. In order to provide metaltongues 29 of the proper flexibility and stiffness, the supporting disc 26 is preferably formed of a suitable thin malleable metal. When the cap 18 is turned down on the thread It toa position in which the flange I9 is against or closely adjacent to the flange H, the supporting disc 26 is moved toward the outer end of the through the neck and the cap.

The band 30 is formed of flexible material, preferably thin springy metal, and has its edge at the rolled over portion slitted at closely spaced intervals, as indicated at 33, to provide a plurality of flexible tongues at the inner edge of the rolled over'portion. These tongues are of sufficientlength and flexibility to permit the cap flange l9 and container neck flange I! to pass through the rolled over portion of the band, as shown in Fig. 1a, without exceeding the elastic limits of the material, to permit assembly of the band with the cap and the container neck.

Fig. 2 illustrates the same construction as that shown in Fig. 1 except that the cap I8 is formed entirely of metal, in which case the band 30 may be made integral with the metal cap in order toavoid the necessity of providing separate pieces and the closure is shown in open position. The band, however, may be made separately, if desired, and associatedwith the cap in the same manner as that illustrated in Fig. 1. Otherwise, the construction shown in Figs. 1 and 2 are substantially identical.

In the arrangement illustrated in Fig. 1, the cap is provided with an indicating marker as designated at 34 in Fig. 3, and the upper surface of the end wall portion l2 of the container is provided with indicia as designated at 35 to 39 inclusive, indicating the operational position of the cap for determining the rate at which the contents are to be dispensed, and is also provided with directional arrows, as indicated at 40 and 4|, which disclose the direction of rota- In the somewhat modified arrangement trated in Figs. 4 and 5, a container, generally indicated at 42, of cylindrical or other desired form is provided with an inwardly extending end wall or flange 43, from which extends a hollow neck 44 having an internal bore or aperture 45. This neck is provided exteriorly with screw threads 46 and with an outwardly extending annular flange 4? near the end of the neck connected to the container. .At its outer end the neck is provided with a reduced cylindrical portion 48 provided with a terminal bead 49.

A cylindrical cap, generally indicated at 50 is threaded upon the neck 44 and'is provided at its open end with an outwardly extending annular flange 5|. At'its end opposite flange 6| the cap is necked in as indicated at 52 and is provided with an internal shoulder 53 at the junction of its cylindrical portion with the necked-in portion 52. At the outer end the cap is provided with a, pouring aperture '54 surrounded by an annular lip 55.

A supporting disc 26, which may be identical in all respects with the disc illustrated in Figs. 1, 2 and 6, is carried internally of thecap 50 and bears at its outer edge portion against the shoulder 53. This disc is provided with a seal member 21 and a circular series of apertures 28 as described above. In this somewhat modified arrangement, an annular, bowl-shaped, washer or gasket, generally indicated at 56, is operatively disposed between the outer end of the container neck 44 and the interior of the cap 50 and cooperates with the seal support 26. This resilient washer or gasket 56, shown in elevation'in Fig. '7, is provided with a central aperture surrounded by an inner annular head 51 which fits tightly about the reduced extension 48 of the neck 44 between the annular shoulder 58 and the bead 49. The annular wall of the gasket or washer is curved outwardly and upwardly from-the bead 51 to an outer circumferential bead 59 at its outer end. The wall is preferably thickest against the bead 51 and gradually reduces in thickness as it approaches the head 59. Preferably the head 59 includes a stiffening rim 60 of wire or other suitable material. l

The bead 59 presses against the inner surface of the cap 5e and against the under surface of the seal support 26 to provide a fluid tight seal between the container neck and the cap and to hold the disc 26 resiliently against the shoulder 53. When the cap is screwed outwardly on the container neck, as is illustrated in Fig. 4, the asket 56 tends to move the disc 26 and seal 21 with the cap to a position in which the seal is spaced from the outer end of the container neck 44 to permit contents of the container to flow through this space and through the apertures 28 in disc 26 to the pouring or dispensing aperture 54 of the cap. When the cap is screwed inwardly on the container neck the gasket or washer 56 is deformed or compressed, as is clearly shown in Fig. 5, but retains its bead portion in contact with the container neck and with the inner surface of the cap 50 so that a fluid tight seal between the container neck and the cap is maintained at all times and any leakage of container contents between the screw threads on the container neck and the cap and outwardly at the base of the container neck is precluded. In this case the cap is permanently retained on the container by a band 30 which may be identical with the corresponding band 30 shown in Figs. 1 and 2 .and described above, this band engaging the flange 5| on the cap and the flange 41 on the 6 container neck to prevent separation of the cap from the container.

A slightly modified form of resilient gasket and seal supporting disc is shown in Fig. 8. In this arrangement the resilient gasket 56' is the same as the gasket 56 illustrated in Figs. 4, 5, and 7 and described above except that the stiffening rim 60 is omitted from the outer bead 59. In thiscase the outer bead 59' is gripped in a rolled peripheral channel or bead 6| provided on the modified seal supporting disc 62 so that the disc performs the double function of stiffening the outer end of the resilient gasket and supporting the seal 21 in the manner indicated above. The disc 62 is provided with apertures 63 surrounding the seal 21 and functions in the same manner as the discZGdescribed above. In this case, the disc itself, being held firmly in engagement with the internal shoulder 53 of the cap provides a sufliciently tight seal between the resilient gasket and the cap to preclude any leakage of container content past the overlap of the cap and the container neck.

In the arrangement shown in Fig. 9, the container, generally indicated at 64, which is shown as formed of glass, has a narrow curved end wall or flange 65 corresponding to the walll2 in Fig. 1 and the wall 43 in Fig. 4 and a large diameter cylindrical neck 66 having at its outer end an inwardly directed end wall or flange 61 from which projects an apertured boss-like structure 68. This arrangement is particularly designed for dispensing granular material, such as salt, sugar, etc. The cylindrical portion of the neck 66 is provided with external screw threads 69 which receive screw threads provided internally of a cylindrical cap, generally indicated at 16. At its outer end the cap is provided with an inwardly directed end wall or flange H in which there is a central aperture 12 surrounded byan annular lip 13. A closing weight 14 is mounted in the aperture 12 and comprises a generally spherical portion 15 and a generally flat-central portion 16 connected to the spherical portion by a reduced neck portion 11 having a diameter smaller than the diameter of the aperture 12. The flat-central portion is spaced from the spherical portion by an amount such that when the weight 14 is in an intermediate position in the aperture a dispensing passage is provided between the spherical portion of the weight and the surrounding lip of the cap HI. The flat portion 16 has a width less than the diameter of the cap aperture to provide openings, one at each side of the flat portion for the passage of containercontents into the cap aperture.

A gasket or washer 18 of resilient material, such as natural or synthetic rubber, rests'upon the upper surface of the neck wall 61 and bears against the outer surface of the boss-like structure 68 and also against the surrounding internal surface of the cap 10. This washer is provided with an annular external bead or extension 19 which fits into a groove provided in the inner surface of the cap so that the washer is fixed to the cap and is constrained to move with the cap outwardly and inwardly rubbing along the outer surface of the boss-like structure 68 of the container neck. The washer is also provided with an upstanding bead or extension which bears against the under surface of the seal supporting disc 8| outside of the circular series of apertures 82. The outer surface of the disc 8! opposite the extension 80 bears against an annular shoulder 83 provided interiorly of. the cap at its. outer. end,

7 A seal 80 carried by the disc 8| covers ,the'end of the boss-like structure 68 and closes the dispensing aperture 85 extending through this structure when the seal is held in sealing position against the outer end of the container neck.

When the cap is screwed inwardly on the container neck, as illustrated in Fig. 9, the seal 84 is held in sealing relation against the outer end of the boss-like structure 68 closing the aperture 85. When the cap is screwed outwardly on the container neck the resilient washer or gasket I8 is moved outwardly with the cap retaining the seal supporting disc 8| against the shoulder 83 thereby moving the seal to a position in which it is spaced from the end of the portion 08 of the container neck providing a dispensing passage through this space and through the apertures 82 in the disc 8|. The contents of the container may then pass into the space between the supporting disc 8| and the end wall of the cap. If the weight I4 is in position closing the dispensing aperture I2 the contents will be held in this space but after the weight is moved upwardly opening the dispensing passage between the weight and the lip 13 the container contents held in the above mentioned space may then flow through the dispensing passage.

In this case the cap may be permanently associated with the container if desired but as this arrangement is particularly adapted for such containers as salt shakers, sugar dispensers, etc., it may be preferable to permit separation of the cap from the container for filling of the container, this arrangement being illustrated in Fig. 9. The fluid tight seal provided by this arrangement will prevent clogging and deterioration of the contents by exposure to atmospheric moisture.

In the arrangement shown in Fig. 10, the container 86 is provided with an end wall or flange 81 from which extends a hollow cylindrical neck 88 provided with external screw threads 89 and having a dome-shaped end from which extends an apertured boss 90 provided with an external groove 9! which may be of generally rectangular cross section. A cylindrical cap, generally indicated at 92, is provided with internal screw threads received by the threads 89 and above the screw threads with an inwardly curved shoulder 93 and an annular radial shoulder 94 above the shoulder 93. Above the shoulder 94 the cap has an inwardly directed annular flange or end wall 95 provided with a central aperture 96 surrounded by an upstanding annular lip 91. A resilientsealing washer 98 has a central aperture surrounding the boss 90, the portion of the washer surroundingthe aperture being received in the groove 9I and an outer edge bearing against the curved annular shoulder 93 of the cap. This washer has a radial wall thickness which decreases uniformly from the inner aperture to the outer edge, the outer edge which contacts the cap shoulder being relatively sharp and flexible to maintain a fluid tight seal between the container neck and the cap.

. A seal supporting disc 99 is mounted in the cap by wedging the rim of the disc between spaced internal ribs I2.I in the cap and is firmly seated against internal cap shoulder 94. This disc carries a concentric sealing disc I which cooperates with the outer end of the boss 90 to seal the container and is provided with apertures IOI surrounding the sealing disc for the passage of container contents through the supporting disc.

, A stem I02 extends from the center of the supportingmember 99 throughthe dispensingaperture 96 in the cap and terminates outside of the cap for removing the supporting disc and seal from the cap for cleaning. With this arrangement when the cap 92 is screwed inwardly on the container neck the disc I00 is forced into sealing engagement with the outer end of the boss 90. When the cap is screwed outwardly to the position illustrated in Fig. 10 the disc 99 is moved to a position spaced from the end of boss to permit passage of container contents past the seal and through the cap aperture.

The arrangement shown in Fig. 11 is similar to that shown in Fig. 10. The container neck, however, is provided with agenerally cylindrical terminal portion I25 having no exterior groove, and an annular washer I26 of resilient material is forced into the cap and holds the seal support disc 99 against the cap shoulder. The washer has a light sliding fit with the external surface of the neck extension and surrounds the neck extension in a manner to return any portion of the container contents in the space between the outer end of extension I25 and the cap end wall into the container when the container is uprighted.

In the arrangement shown in Fig. 12, the neck I03 of the container, generally indicated at I04, is provided with an elongated cylindrical apertured boss I05 and the cylindrical cap, generally indicated at I06, is'provided with a continuous end Wall I01 provided with a central aperture I08 surrounded by a circular series of apertures I09 and is provided internally with an annular radial shoulder H0. The seal supporting member III carrying the disc I I2 of sealing material is secured in the cap by a metal cylinder H3. Cylinder II3 is forced into the cap and frictionally engages the interior side walls of the cap to hold the seal supporting disc against the internal annular shoulder. of the cap. An apertured washer Ill of suitable sealing material is secured in the cylinder I I3 and fits closely about the elongated boss I05, to provide a seal between the cylinder and the boss. This sealing washer may conveniently be secured in the cylinder by beading the lower edge of the cylinder over an extension on the disc, as indicated at H5 and moves with the cap, sliding on the surface of boss I05.

The seal supporting disc III is provided with a circular series of apertures H6 which register sufficiently with the series of apertures I09 so that when the cap is screwed outwardly and the disc H2 is spaced from the end of the boss I the container contents may fiow through the space between the end of the boss and the sealing disc and through apertures H6 and I09, when the container is inverted. When the cap is screwed down on the container neck the disc I I2 is brought into sealing engagement with the boss I05.

A stem II! is attached at one end to the center of seal supporting disc III and extends through the central cap aperture I08. This stem is used to force the disc III and the cylinder II3 out of the cap in order that the cylinder and disc may be cleaned, repaired or replaced.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawings and described in the specification but only a indicated inthe appended claims.
