19 Claims. (Cl. 221-60) with the extrusion of the tube. it is equally applicable as a bottle nozzle closure means, provided, if desired, with a depending flange similar to the upper end forming flange of a collapsible tube and also, if desired, with a nozzle extension projecting downwardly therefrom adapted to fit within a cork to secure it to the top of the bottle, or with the nozzle itself being provided with an extension going around the neck of the bottle. It is apparent when it is applied to cans and containers, either the whole can or container or the top of the container only may be extruded or formed simultaneously with the formation of the nozzle and valve seat. The invention is adapted to dispense materials in powder form and more particularly is adapted to dispense materials in plastic, semi-plastic partially liquefied form or liquid form and to provide at all times a positive closure for the nozzle means thereof which will not leak and has been proven in tests not to leak with water, glycerine or other types of chemicals over a long period of time.

While I am aware that others have provided nozzle closure means for containers, bottles, cans, tubes and the like having at least a partially spherical closure member functioning as a valve and rotatably mounted in a suitable formed valve seat in the nozzle thereof, so far as I am aware these have been largely paper patents either impossible to manufacture or only made at a. great expense. I believe that I am the first, therefore, to provide a nozzle closure means of this type which may be manufactured on a practical commercial basis in the manner described herein and which is positively liquid, chemical and air resistant, and in which the valve forms preferably with a countersunk washer a liquid chemical and air resistant positive joint when in closed position, and which may be readily manufactured in the simple mannershown herein and at a cost to make this type of a valve closure means possible under competitive conditions with other types of closure means now on the market.

As stated, hitherto the great difliculty with devices of this description has been that the valve action is not air or liquid resistant. An object of my invention, therefore, is to provide a nozzle closure means of this general description in which the valve action is air, liquid and chemical resistant, and to this end I broadly provide, in combination, a valve seat constructed of thin more or less slightly yieldable metal preferably in such a manner that it of itself may be slightly yieldable, and construct the valve itself preferably of a predetermined chemical resistant preferably slightly yieldable composition material which functions in combination with the metal of the valve seat to form a substantially yieldable air and liquid tight joint at all times.

As a further precaution to insure an air tight, liquid tight joint I preferably provide in the valve seat a countersunk preferably resilient fibre or other type of washer to positively bear against the oscillatable valve at all times to insure a tight 'joint, said washer being preferably countersunk within the valve seat to keep it in accurate alignment therein at all times.

Great difliculty has been hitherto experienced in the manufacture of collapsible tubes, containers and closure means therefor, in providing a closure joint resistant to the specific chemicals which may be contained within the contents of said cans, containers, tubes, bottles or the like. By employing plasticizable composition material I have been able to select the materials of which the valve is made to make it resistant specifically against the known chemicals in the contents of the container, for instance, resistant to mild acids, alkalis, alcohol, other solvents, etc., and I therefore construct the material of which my valve is preferably made of predetermined chemical characteristics to be so resistant.

Further objects of my invention are not only to provide a nozzle closure means of the type mentioned above which may be readily and simply manufactured, but also to provide one which will positively oscillate and which will function to close or open the nozzle at all times. I preferably provide a turning lug projecting upwardly not tend to slip around within the valve seat,

so that the end or ends thereof will not come into accurate alignment with the nozzle end or ends. Inorder that the turning lug may positively function to both open and close the valve,

1 construct it so that in closed position the upper surface thereof projects substantially tangentially from thetop of the valve, so that it may be readily opened, and provide the end of said lul; having a tangential upper surface with an upturned portion to form an upwardly projecting tip or projection for the ready oscillation of said valve from an open to a closed position.

Further features of my invention relate to the improved method of manufacture of and certain details of construction thereof so that it may be readily manufactured in a commercial and practical manner. 'nius I preferably mold the valve closure member with flattened opposite sides to assist in forming an axis of rotation therefor and I provide centrally thereof outwardly projecting pivot lugs of a length with the said adjacent central valve portion of substantially the exact diameter of said sphere, so that if the valve be molded in hemi-spherical molds, the mold line will substantially pass through the centers of said flattened side portions and said lugs to permit the ready removal thereof in an easier manner than if indentations were provided in said flat portions which would be hard and almost impossible to remove from the molds; and, as the total length of said pivot lugs taken through the axis thereof is not greater than that of the diameter of said sphere, they may be more readily removed from the molds. A further detail in the construction of my valve which makes pressure molding thereof possible is the particular shape of the turning lug I preferably employ which includes a curved lower surface and a flat upper surface substantially tangential to said spherical valve and terminating in an upward bent outer end meeting said lower surface to form an outwardly projecting lug, being so shaped for a double purpose, namely, so that said integrally molded lug may be readily pivoted out of a hemi-spherical valve mold by pivoting it therefrom on the point of contact of said mold with the lower surface of said lug, and to provide a turning lug engageable by the finger which will oscillate the valve in either direction.

A further feature of my valve construction is that I provide means for readily pivotally attaching it on a flxed axis within the relatively thin upper portion of the nozzle wall, it being only necessary to insert the valve closure member within the partially spherical extruded recess or lower valve seat portion and press inwardly diametrically opposite portions of said relatively thin nozzle upper wall against said diametrically opposite flat valve portions to cause the pivot lugs to be imbedded within the nozzle wall to form sockets to receive said pivot lugs to provide an axis of rotation for said valve.

Further features of the inherent construction of my improved closure device are that I provide a nozzle which may be readily extruded from a circular, annular or other type of blank in the form of a nozzle having a partially spherical lower valve seat portion in a thickened orlower portion thereof and a relatively thin upper wall projecting substantially vertically upwardly from said lower valve seat portion which, after the insertion of the valve member therein, may be readily crimped downwardly over said valve to provide a supplemental partially spherical upper valve seat portion for' the upper portion of said valve to firmly retain it in position against said 'washer where employed and said lower valve seat portion formed during the extrusion process.

A further feature of my particular construction is that the countersunk annular recess for receiving the washer may be readily extruded in the valve seat simultaneously with the extrusion of the nozzle and also, if desired, supplemental metal saving recess means may be formed'in the lower surface of said thickened portion to save the expense of additional metal; or, if desired,

-the valve seat may be formed from an inwardly depending annular flange projecting inwardly from said nozzle. If desired, however, the countersunk washer-receiving recess may be readily formed in the upper portion as well as the lower portion of said valve seat during the extrusion process.

face of said thickened portion underneath said valve seat being partially removed to save metal; preferably extruded simultaneously with a flange projecting outwardly from a downwardly depending nozzle extension or a complete container or tube as shown.

Further features of my invention relate to the various features of construction of my valve and nozzle members hitherto described which function to provide a novel method of assembling them into a nozzle closure unit which may be entirely manual, semi-automatic, or completely automatic.

Further features of my invention are to provide an improved apparatus for such assembly, being either fully automatic or requiring at the most a single operator. By providing the valve structure hitherto described and the valve seat structure also described in said nozzle, I have provided a construction whereby the nozzle may be readily mounted on a rotatable ring or conveyor and the following sequence of steps performed thereon during intermittent intervals of movement of said rotatable ring or conveyor, namely, (1) the mounting of said nozzle on suitable means on said conveyor, (2) manufacture, shaping and insertion of the flbre washer within the countersunk valve seat in the lower valve seat portion of said nozzle or upper valve seat portion, if desired, (3) the insertion of the oscillatable valve closure member so as to abut said washer and lower valve seat nozzle portion in correct alignment, (4) the downward crimping of said nozzle upper wall toprovide a partially spherical upper valve seat portion enclosing said valve member and firmly securing it against said washer and said lower valve seat portion, (5) the inwardly pressing diametrically opposite portions of said relatively thin upper wall against said diametrically opposite flattened valve portions t?) form flat abutting surfaces to accurately align the axis of oscillation of said valve within said nozzle and to simultaneously press the pivot lugs where employed into the relatively thin nozzle wall to form sockets therein to receive said pivot lugs to positively provide an axis of rotation for said valve member to keep the discharge passage thereof in the desired alignment with the dispensing holes at the upper and lower ends of said nozzle when in open position, (6) oscillating said valve turning lug to move said valve member to a position closing said nozzle either by hand or by automatic means if desired, (7) again crimping the upper portion of said nozzle wall over said valve member to'align said hollow upper valve seat portion and seal said valve in a shipping position and, (8) removing said assembled nozzle from said conveyor or ring. If desired, however, the first and second crimping steps and inwardly pressing axis forming steps may be performed simultaneously, the portions of the upper side wall of the nozzle being pressed inwardly against the flat diametrically opposite valve side portions to provide the flat abutting surfaces and lugsockets to provide a true axis of oscillation for said valve member while the upper end of said nozzle wall portion is being bent downwardly over the upper surface of said valve to form the upper valve seat portion, it being apparent that these two operations are performed simultaneously with the crimping step, preferably maintained slightly longer. In my preferred embodiment, I have shown mandrel means for supporting thenozzle during this sequence of steps and indexing means to advance said ring or conveyor amounts to progressively change stations to permit the above described sequences of assembly steps to be performed thereon during the intervals between said progressive advancements. It is obvious that any type of continuous conveyor may be employed and in my preferred embodiment I preferably employ a ring rotatably mounted on a suitable standard on which the desired tools to accomplish the steps described are mounted on the respective stations thereof to perform the actual work thereon at these stations between the intermittent intervals of movement of said conveyor or ring.

Further features of my invention are therefore to provide a novel type of apparatus for this method of assembly which may be done either by hand, semi-automatically, or fully automatically to save the number of operatives required.

While my invention is particularly applicable for use in the manufacture of collapsible tubes, cans, containers, etc., which may have either the upper portion or entire body thereof simultaneously extruded with the formation of the nozzle, it is apparent that my invention may be equally applicable to bottle closures which may also be provided with an outwardly projecting annular flange analogous to a can or container top or collapsible tube top and if desired the nozzle portion may be extended below said spherical valve seat portion in the extrusion process to provide means whereby an annular cork or other device may be employed to surround said extruded nozzle for insertion within a bottle neck. If desired, the entire valve closure member may be constructed hollow and the valve seat portion of the nozzle similarly enlarged if necessary so as to receive and dispense a predetermined bulk of powder, liquid, or other material contained within said hollow valve. For this purpose I preferably provide the hollow valve seat portion with a single discharge end and I preferably construct the cooperating surfaces of the nozzle side wall and the nozzle inlet and outlet holes so that the predetermined bulk holding hollow valve may be moved to three positions, namely (1) a position to fill said hollowvalve when the bottle or container is in inverted position, (2) to a loaded position in which the hollow valve is turned so that the discharge vent is completely sealed by the side wall of the nozzle, which position may provide a convenient loaded position taking a much less time to dispense from than if first filling the hollow valve portion and immediately discharging it, and (3) to a position bringing the discharge vent in the hollow valve member into substantial alignment with the nozzle discharge hole for discharging. This specific embodiment of my invention is specifically adapted for usewhen serving liquors at a crowded bar, as the bar-keeper may at intervals load up the hollow valve member and pivot it to loaded or cooked position again ready for immediate dispensing.

These and such other objects of my invention as may hereinafter appear will be best understood from a description of the accompanying drawings, which illustrate various embodiments of my invention applied to collapsible tubes, or containers, bottle-tops, and various steps in its method of manufacture and apparatus suitable therefor.

In the drawings, wherein like characters of reference indicate like parts throughout, I8 generally indicates a nozzle closure means for containers, constructed in accordance with my invention. The nozzle closure means ill may have the annular flange l2- projecting radially outwardly and also downwardly therefrom to which the side wall M of the collapsible tube may be attached, or if desired, with my nozzle closure means it may be employed as a bottle top as shown in Figs. 11 and 13. My improved nozzle closure member l0 includes a preferably hollow preferably extruded preferably metal nozzle member l8, preferably having the lower portion 18 thickened as at 20 and having a central dispensing hole means 22 therein, said lower portion i8 preferably having a partially spherical preferably slightly yieldable lower valve seat portion 24 on the inner surface thereof extruded thereon at the same time that the nozzle portion I6 is being extruded, and also extruded simultaneously with the flange I2 if employed, and the container or tube side wall I 4 or, if desired, simultaneously with the nozzle extension 26 as shown in Figs. 11, 13 and 15. In the embodiment shown the lower valve seat portion 24 is preferably substantially hemi-spherical. The flange I2 may, as shown in Fig. 1, be the means to secure said nozzle member to a container, bottle, tube, can or the like such as by forming the wall I4 integral therewith as shown in Fig. l or other means may be provided, if desired, to secure said bottle, tube, can, container or the like, such as by providing an annular cork member 28 adapted to surround the extruded nozzle portion 26 as shown in Figs. 11 to 15 adapted to be slightly yieldable contained within the bottle neck.

My invention broadly includes a preferably substantially spherical valve closure member 32 mounted within the upper end of said nozzle i6 and provided with a discharge vent or passage 34 and a suitable axis of rotation 36 and preferably a turning lug 28 whereby said valve closure member 32 may be oscillated to positions bringing the discharge vent or passage 34 thereof in alignment with the inlet hole 22 in the lower portion of said nozzle and/or the outlet hole 48 in the upper portion of said nozzle. While I am aware that substantially spherical valve closure members of this general type have hitherto been provided for nozzles, so far as I am aware they have tended to leak, and to aid in preventing the leakage thereof I have provided washer nieans 54 adaptably to be countersunk within the valve seat 44 formed in said nozzle said valve seat 44 includes the lower valve seat portion 24 and the upper valve, seat portion 46 to be described. Where a collapsible tube is employed I preferably suitably countersink the circular washer 66 in a countersunk recess 42 in the lower valve seat portion 24, but may, if desired, as shown in Figs. 15 and 17 countersink said washer recess 42 in the upper valve seat portion of the nozzle.

As to be explained later in connection with Figs. 19 to 22, I preferably extrude my improved nozzle member l6 and simultaneously provide it with a lower valve seat portion 24 in a thickened portion of said nozzle and I may simultaneously therewith extrude the annular washer receiving recess 42 therein. In order to save metal I also preferably provide metal saving recess means preferably in the form of an annular groove 48 on the lower surface of said thickened portion 20 or I may, as shown in Fig. 10 so construct the recess 48' as to substantially form as the lower valve seat portion 24 the annular slightly yieldable flange 24' projecting arcuately inwardly substantially centrally of the side wall 50 of said nozzle. In my preferred embodiment each recess, namely the washer receiving recess 42 and the annular metal saving recess 48, are preferably concentric with the dispensing hole means 22 in the lower portion of said nozzle substantially centrally of the lower substantially hemi-sphericai valve seat portion 24. After the extrusion process, the upper portion 62. of the side wall 50 of said nozzle projects substantially vertically upwardly from the upper edge of said lower valve seat portion 24. In the embodiments shown in Figs. land 22, the annular flange l2 projects outwardly and downwardly from the lower portion 54 of said nozzle wall 50.

As stated hitherto. in order to prevent leakage through my improved valve closure means I6, I preferably provide a washer 56, mounted in said countersunk annular washer receiving recess 42, preferably constructed of fibre, leather, rubber or other suitable preferably resilient material of a greater thickness than the depth of said recess 42 to at all times closely engage the oscillatable valve closure member 32 to form an air and liquid tight seal at all times therewith, and being constructed preferably of material where liquids are employed resistant to the chemical constituents thereof.

In the preferredembodiment shown, I preferably extrude the nozzle portion l6 and integral flange l2 where employed and tube or container side wall l4 where employed or nozzle extension 26 where employed of metal. And whereas I may make my improved valve member 32 of metal to provide a metal to metal contact, this is not at all times thoroughly air and liquid proof and I therefore preferably construct my improved substantially spherical valve member 32 of predetermined chemical resistant composition material and one of which the constituents thereof may be predetermined to be resistant to any specific chemicals contained in the contents of the container, such as mild acid, weak or strong alkali, alcohol, or other solvents, etc. Said improved valve member 32 is pivotally oscillatably mounted on said'valve seat 44 on a horizontal axis 36 against said washer56. In order to provide a suitable axis of rotation and a. construction which may be pressure molded in two superimposed substantially hemispherical molds, I provide diametrically opposite flattened side portions 68 on said valve member 32 as more particularly shown in Figs. 4, 7, and 8 provided with pivot lugs 66 preferably having rounded ends as shown and proferably projecting outwardly centrally of said flattened side portions 58, and of a length with said adjacent central valve portion, of substantially the diameter of the sphere of which my improved valve member is preferably molded for a double purpose, (1) so that lugs 60 will not be of such a length as to prohibit their being removed from the molds, they being normally so placed as to lie substantially on the mold line between the two hemispherical molds, and (2) so that they may be readily dropped tothe desired feeding position within the diameter of said nozzle against the partially spherical lower valve seat portion 24 thereof. Portions of said nozzle member side wall 60 are diametrically pressed flatly inwardly as at 59 against said flattened valve sides 58 to assist in providing an axis of oscillation for said valve portion 32 and to form sockets 66 therein as shown in Fig. 4 to receive said pivot lugs 60 diametrically of said wall 56 to provide an axis of oscillation for said valve member 32, and the upper portion 52 of said vertical nozzle member side wall is preferably crimped downwardly over said rotatable valve member to form a hollow partially spherical upper valve seat portion 46 having a central dispensing hole means 46.

Said valve member 32 is also provided on the upper end thereof with a turning lug 38. Said lug 38 is preferably formed with a curved lower surface I2 and a flat substantially tangential upper surface I4, terminating in an upwardly bent rounded outer end 16 meeting said curved lower surface I2 to form an outwardly projecting lug l6 projecting radially outwardly from said valve member 32, being thus shaped for a double purpose, (1) so that said turning lub may be readily removed from a hemi-spherical mold on pivoting said closure member therefrom, the inner end of the lower curved portion 32 forming an axis for said pivoting, and (2) to provide means whereby the closure member 32 may be readily oscillated in either direction, namely, to open by grasping underneath the lower curved portion and to close by grasping the inner portion of the upwardly projecting lug I6 thereof, thus providing means to oscillate said valve an amount limited by said turning lug 38 abutting opposite edges of said dispensing hole means 40 in said hollow crimped upper yalve seat portion 46. As stated, said valve member 32 is also preferably provided with a discharge vent 34 either at one end thereof or passing therethrough. of such a size and so located relative to the center of said valve, and said nozzle side wall 50 and the upper and lower dispensing holes 40 and 22 respectively of said nozzle l6 are of such a size and shape that said discharge vent or passage 34 may be rotated into alignment with the respective discharge hole means 40 and 22 in the hollow ends of said nozzle valve seat 44 with the outwardly projecting end 16 of said lug abutting as shown in Fig. 15 ina suitably countersunk hole 42 in the upper valve seat portion 46. While I have shown, for reasons to be explained, my im proved type of means for oscillatably pivotally mounting the valve closure member 32 in said nozzle, in place of the pivot lugs 60 hitherto described, I may as shown in Fig. 9 provide suitable sockets 50' in the flattened side portions 54 of the valve member to receive the pivot lugs formed from the nozzle side wall 52 when diametrically opposite portions of said side wall are pressed inwardly as hitherto explained. The vent or passage 34 of my improved valve member is preferably shown located substantially near the center thereof and passing therethrough but it is obvious that if desired it may be located along the side thereof as suggested in Fig. 13 or through any portion thereof. It is also obvious that the valve seat 44 including the lower valve seat portion 24 and the upper valve seat portion 46 may be formed in any other desired manner than in the manner shown. While I preferably employ an extruded metal nozzle it is apparent that if desired the nozzle portion may be molded or extruded out of composition or the like material, cast or otherwise fabricated and while I have preferably constructed our improved valve closure member of molded composition material, it may if desired be suitably fabricated in any desired manner out of other material; As explained hitherto, by constructing the valve seat of slightly yieldable metal material and by constructing the valve of slightly yieldable composition material I have found that a true cooperation exists therebetween, providing substantially an air and liquid proof joint at all times and one in which there is substantially no wear as in a metal to metal contact, permitting the use of my improved nozzle closure means over a long period of time. In order that a more slightly yieldable lower valve seat portion 24 may be provided, a. larger metal saving recess 46' may be provided and particularly when extruding aluminumI may extrude the lower valve seat 24' in the form of a slightly yieldable annular flange depending arcuately inwardly from the center portion of the nozzle side wall to the central dispensing hole 22.

As explained, I have shown in Fig. 5 the axis of rotation of the valve member 32 on said nozzle member I! formed not only by the flattened side portions II of the valve and adjacent flat portions I. of the nozzle side wall but in place of the pivot lugs projecting outwardly from the valve into sockets 64 formed in the adjacent nozzle wall, I have provided the recesses ill in said valve to receive the pivot lugs 58 formed in said nozzle side wall when said nozzle side wall is pressed inwardly on diametrically opposite points thereof in the manner hitherto explained.

I have shown in Figs. 11 to 18 various forms of my invention particularly adapted as closures for bottle tops, the embodiments shown in Figs. 11 to 14 being constructed substantially similarly to my invention as shown in Fig. 1 applied to a collapsible tube except that the side wall of the tube I4 is omitted from the flange l2, the nozzle II is extended downwardly as at 24 and provided with an annular cork ring 20 for securing my improved closure means within the bottle neck 30.

In the embodiment shown in Figs. 11 and 12, the

discharge passage 84" of said valve may be taperedasshown andofasizetodispenseasingle drop at a time from the interior of said container may as shown be applied to the neck 30' of a liquor bottle and in addition to the discharge passage 34 is provided with the air inlet passage 18 to rapidly admit air within the bottle to permit the rapid discharge of the liquid contents thereof through the discharge passage 24 of said valve member 32'. It is apparent, however, that the discharge passage 84 may be constructed at the side of the closure instead of through it as the air inlet passage 18 shown in Fig. 14, or that, said discharge passage 34 may comprise any desired part of a sphere up to a hemi-sphere. If the discharge passage 34 be located at the side however and substantially enlarged, it is not any wherenear so desirable as the type specifically shown herein for ease of manufacture and assembly, but may for some features of my invention be provided. v

I have shown in Figs. 15 to 18 embodiments of my invention adapted to dispense a measured dose of predetermined bulk from the container and for this purpose I have enlarged the vent 34 so as to substantially take up the entire interior of said valve member 32 and I have correspondingly enlarged the adjacentv substantially spherical valve seat portion 44* of said nozzle wall. The hollow closure and vent are preferably of such a size and shape and said nozzle side wall and lower and upper dispensing hole means 22 and 40' thereof respectively are preferably of such a size and shape that said hollow closure vent 34 may be rotated into alignment with said lower dispensing hole means 22" when said closure means is inverted to permit reception of said measured dose or quantity within said hollow closure member with said turning lug 38 abutting one edge of said nozzle hole means 4|)"; oscillated against the friction of said composition closure member 32 against said metal valve socket 44 to bring said hollow closure vent 34 opposite said nozzle side wall 50 into intermediate loaded or cocked dose or drink-holding position, so as to be frictionally retained therein; or, rotated into alignment with said support dispensing hole means 40 to expel said measured dose therethrough with said turning lug 38 substantially abutting the opposite edge of said upper nozzle hole means 40. I have shown in Fig. 15 this embodiment of my invention applied to a neck 30' of a liquor bottle provided with the elongated nozzle extension 26 and being secured within said neck by the annular cork 28, the flange l2 in this instance being omitted. While it is possible to extrude this nozzle it is not so easy as the extrusion of the other nozzles shown and described hitherto and if desired the nozzle portion l8 may be cast, stamped .or otherwise shaped for this embodiment. I have shown in Figs. 1'7 and 18 an embodiment of my invention similar to the embodiment shown in Figs. 15 and 16 but particularly adapted for dispensing a measured dose of powder. In this instance the lower nozzle discharge port 22'' is made relatively small so that the closure member 32' may be oscillated or rotated into three positions, namely the filling, loading, and dispensing positions, as shown in full or dotted lines respectively therein. In this instance the lower nozzle extension 26 is widened to fit outside of the neck 20' of the bottle and is provided at its lower extremity with the inwardly projecting lip 29 providing means to secure my improved nozzle closure member Iii to the bottle. In this embodiment the nozzle means li may be conveniently molded.

As stated hitherto, I have preferably provided in the specificdetails of my construction both a valve closure member 32 which may be readily fabricated in a simple manner and a nozzle portion I8 which may be also extruded or otherwise fabricated in a simple manner, the nozzle being preferably constructed of metal and the valve member being preferably constructed out of molded composition material so as to yieldingly abut each other and form an air and liquid tight non-wearing joint in use better than it is possible to obtain by composition against composition or metal against metal. I have also constructed the details of my improved valve structure with a view to a simple method of its manufacture. I thus, as explained, provide a substantially spherical slightly yieldable closure valve member preferably consisting of hemispherically molded predetermined chemically resistant composition material having the diametrically opposite fiat sides 58, having the pivot lugs 6|! projecting outwardly centrally thereof, of a length with said adjacent central valve portion of substantially the'diameter of said valve for easier removal from a heml-spherical mold and for easy insertion within said nozzle member with said mold line passing therethrough and a turning lug 38 at the upper end thereof preferably having a curved lower surface 12 and a flat substantially tangential upper surface 14 terminating in an upwardly extending outer end 16 meeting said curved lower surface I2 to form an outwardly projecting turning lug l6 shaped to be removed on pivoting thereof from said hemispherical valve mold and. a discharge vent 34 therein or therethrough substantially at right angles tothe diametrie axis of said pivot lugs 60. As stated hitherto, my improved valve closure member may be constructed in this specific manner out of any suitable material, but for the reasons described and for the additional reason that composition material may be brightly pigmented or otherwise colored with any desired color to provide an attractive contrast with the metal nozzle, I preferably construct it of predetermined chemical resistant composition material. While I have preferably formed the axis of rotation thereof by providing the substantially spherical closure member with diametrically flattened sides 58 and pivot lugs 60 projecting outwardly centrally thereof of less total length than the diameter of said sphere for easy withdrawal from the mold and insertion within the nozzle, it is obvious that in place of pivot lugs I may provide the pivot recesses 60' as shown in Fig. 10 or other types of pivot means, such recesses or other types of pivot means being not however so easily withdrawn from the molds, and I may in place of the side portions 58 and lugs 60 provide any type of oscillation axis forming means. While the turning lug 38 at the upper end of said closure means is preferably constructed in the manner described with a double function of easy removal from the mold and being operable to be actuated by a finger to readily oscillate the valve in either direction, it may, if desired, be constructed in other ways than in the specific manner shown. Y

As stated hitherto, for the reasons given above and as a plastic composition material may be readily pigmented or otherwise colored to provide an attractive appearance, I preferably construct substantially spherical closure member of hemi-spherically molded, predetermined chemical be employed, I preferablyemploy one of insoluble phenol formaldehyde intermediate condensation product type such as Bakelite, or insoluble urea formaldehyde intermediate condensation product or an insoluble cellulose acetate product'or in fact any suitable type of moldable preferably resilient composition material. With the widespread range of composition materials possible, it is obvious that I am able to select a composition material particularly resistant against the chemicals in the known contents in the container for which my improved nozzle closure means is desired to be used. Thus, for instance, if it would be desired that the closure member be resistant to alkali or weak acid, I

preferably employ an alkali or acid resistant insoluble phenol formaldehyde intermediate condensation product specially treated'to make it acid and/or alkali resistant. If I desire a valve member resistant to alcohol, I preferably employ an insoluble urea formaldehyde intermediate condensation product or I may if desired employ a cellulose acetate product or any of a great many possible composition materials preferably so selected as to be resistant to the particular chemicals in the'contents of the container.

Employing these materials it is possible to manufacture my improved valve member 32 by pressure molding in two superimposed hemi-spherical molds. 'I'he'hemi-spherical molds are preferably so shaped as to provide the flattened sides 58 and the pivot lugs 60 projecting outwardly therefrom substantially centrally between the hemispherical molds of a length with said adjacent central valve portion of substantially the diameter of said valve and molds. It is apparent, therefore, that the mold line will be formed substantially centrally of thefiattened portions 58 and through the pivot lugs Bl] to permit the easy withdrawal of said pivot lugs from the mold. Thus the particular construction I employ to provide an axis of rotation for the valve member is constructed with a view of its easy manufacture or moldin One of the molds is also shaped to providesaid closure member with a turning lug 38 at the upper end thereof in the manner hitherto described namely preferably with a curved lower surface 12 and a fiat substantially tangential upper surface 14 terminating in an upwardly bent rounded outer end 16 meeting said lower surface to form an outwardly projecting turning lug 38. To provide the discharge vent passage 34 I preferably suitably mount within the molds substantially centrally thereof as desired suitable pin means. When the molding is complete I separate the hemi-spherical molds, remove said pin means from said valve member to provide a discharge vent in said valve member substantially at right angles to the diametric axis of said pivot lugs, and pivot said valve member substantially at about the point where the lower lug surface 12 joins the valve member to remove said turning lug from its hemispherical mold. If desired, the pin means may project through the molds to assist holding them together and may be removed prior to separation of the hemi-spherical molds.

It is understood that my invention is not limited to the specific embodiments of article and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
