A24 Claims.

My invention relates to improvements in noz zle closure means for containers having an oscillatable valve closure member therein and includes the provision of washer means or a packing member for use between a valve seat provided in the nozzle and said oscillatable valve closure member to provide a more airand liquid-proof joint than any hitherto provided. l

l My invention is, in certain respects, an improvement in the type of washer or packing member shown in White 1,967,797 and the type of Washer or packing member and closure means described in the joint patent application of James Rest and Albert H. Church, Ser. No. 751,734, for Nozzle closure means for containers, and the application of James Rest, Ser. No. 48,043 for improvements in Closures for bottles,` collapsible tubes and like containers An object of my invention is to provide such a closure means for containers with a positively airand liquid-tight joint to positively prevent air and liquid seepage through the nozzle closure means. My invention is particularly adapted for use with a nozzle having a partially spherical Valve seat therein, dispensing hole means in each end thereof and an at least partially spherical valve closure member oscillatably mounted within said valve seat. For this purpose, I believe I am the rst to provide a washer or packing flo member constructed of compressible material substantially covering the entire surface of the valve seat for the nozzle closure member. A feature of` my invention relates to making a washer or packing member ina flat shape which 3.3 may be readily and quickly bent into a substantially spherical shape for entirely covering the surface of said partially spherical valve seat, which shape is suggestive of a four-leaf clover, namely a center annular portion having a central 40 dispensing hole therein to lie aligned with the dispensing hole in the lower end of the nozzle and a plurality of leaves, in my preferred embodiment four, projecting radially therefrom preferably having convex sidewalls capable of being bent with said center portion into a partially spherical shape to have the edges thereof substantially abut Without overlap when the washer is bent into the partially spherical shape to substantially cover the valve seat. A `further feature of my invention relates to the provision of a washer or vpacking member provided with a plurality of concentric circular CII grooves therein whereby the Washer or packing 55 member may be more readily flexible, evenly,`

without humps or ridges therein, into a partially spherical shape.4

A further feature of my invention relates to the provision of a Washer or packing member adapted to entirely cover the surface of the substantially spherical valve seat, oi exible compressible material yet provided with a supplemental layer of more compressible material secured on a surface thereof to be compressed between the valve member and valve seat to assist in providing a 10 more airand liquid-proof closure for said nozzle, which supplemental layer may, if desired, be countersunk Within an annular recess in the washer or packing member.

It has been quite diflicult to maintain a hollow l5 washer or packing member of this description in alignment with the dispensing holes in the nozzle, and for this purpose I may provide an annular countersink near the lower dispensing hole in the valve receiving recess in the nozzle to receive, if 20 desired, a portion of the annular layer of the more compressible material therein to maintain the Washer or packing member center in the desired position within the nozzle; or I may, if desired, provide an annular skirt adapted to over- 25 lie the edge of the lower dispensing hole in the nozzle for this centering purpose, which annular skirt may additionally function to overlie and seal the edge of said dispensing hole means if the nozzle be extruded, or otherwise pressure shaped from a blank of coated metal, which is almost impossible to extrude or pressure shape without having the edge of the dispensing means in the lower end of the nozzle expose the metal. Where the base metal of the coated tube comprises lead, it has been believed that a tendency to poison or deleteriously aiect the contents of the container exists.

A further object of my invention is to provide a washer or packing member adapted to com- 0 pletely cover the interior surface of the valve seat provided with a skirt to positively overlappingly seal the exposed metal edge ln the lower portion of a coated metal nozzle.

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 thereof.

In the drawings, wherein like characters of reference generally indicate like parts throughout, represents a nozzle closure means for a container 32 constructed in accordance with my invention. While I have illustrated my improved type of closure valve means 42 applied to the nozzle 34 of a collapsible tube 32, it is obvious that it may be applied for use in a nozzle of any type of container whether it be a bottle, can, collapsible tube or otherwise. As stated previously, my invention is particularly adapted for use in nozzle closure means for containers of a type comprising a hollow nozzle member 34 having a dispensing hole means 36 in the lower end thereof and a dispensing hole means 38 in the upper end thereof and a partially spherical valve seat 40 therein for receiving the movably, preferably oscillatably mounted, at least partially spherical valve closure member 42 therein. The nozzle 34 is preferably extruded from a ductile metal but may be otherwise pressure shaped or fabricated from any suitable metal or other material, and the valve closure member 42 is preferably constructed of a thermoplastic composition material, such as synthetic resin or Celluloid, although it may be constructed of metal or any other suitable material, preferably in accordance with the i disclosures of the application for patent of James Rest, Ser. No. 678,133, the joint application of Rest and Church, Ser. No. 751,734, and the application of Rest, Ser. No. 48,043. In accordance with the disclosures in said applications, said valve closure member 42 is provided with the diametric recesses or dimples 44 into which p0rtions of the wall of the nozzle may be pressed inwardly as at 48 to form single axis of oscillation forming means for said valve member 42 with the recesses or dimples 44 of said nozzle 34. Said at least partially spherical valve closure member 42 is provided with a vent 46 oscillatable to an open position ush with one or both of said respective dispensing hole means 36 and 38 in the respective lower and upper ends of said nozzle 34 or to a closed position against the side wall of the nozzle 34, and for the purpose of oscillating said valve, it is provided with a projection or turning lug 49 projecting outwardly therefrom through the upper end 38 of said nozzle. If desired, said turning lug 49 may be provided with the concave side walls 50 in accordance with the disclosure of the application of Elton C. Church, Ser. No. 101,967, for Nozzle closure means for containers, bottles, tubes, cans andthe like. As stated, Figs,v 13-17 illustrate the construction shown in the joint application of Rest and Church, Ser. No. 751,734, in which an annular washer or packing member 52 is interposed between the partially spherical valve seat and said valve member 42, as shown being located in a countersunk recess 54 formed inthe lower portion of said valve seat around the lower dispensing hole 36 of said nozzle. I have shown in Fig. 18, however, the ridges 55 which tend to form on such a washer or packing member when bent into the partially spherical formation shown. In order for the washer or packing member 52 or the other types of washers or packing members shown herein or, in fact, any washers or packing members to be able to be easily bent into partially spherical shape without forming said ridges, I preferably provide a plurality of concentric circular grooves 58 therein extending throughout a surface thereof if desired-it being obvious that said grooves 58 may be readily stamped in the washer or packing member during the course of its manufacture. It is thus obvious that when the washer or packing member 52 is bent into a partially spherical shape it will readily flex along the lines of said grooves into the partially spherical shape desired without forming the ridges or humps 56 therein. It is also apparent that in use, if the grooves 58 are formed in the surface of the washer or packing member 52 adjacent the valve 42, the edges thereof will form wiping lines to tend to wipe off any plastic or other material protruding from the end of the discharge vent of said valve after i use. In any embodiment of my invention shown,

of rubber and cotton fibers as shown in Patents Nos. 1,524,573 and 1,967,529.

A main feature of my invention, however, as previously indicated, is that I preferably construct a washer or packing member 52 not only having an annular center portion 52 constructed of a flexible compressible layer but one provided with an annular layer 6U of more compressible material, such as rubber or latex, secured preferably by a suitable rubber or other cement to a surface thereof, preferably adjacent the inner edge of said portion 52 or annular washer or packing member 52 shown in Figs. 13-17, and as shown in my preferred embodiment, preferably within an annular recess 52 countersunk within, said supplemental washer 60 being thus secured within said recess by means of the cement 64. I believe I amthe rst, therefore, to provide a washer or packing member comprising two laminated layers,

one comprising a standard washer or packing layer of flexible compressible material and the other comprising an annular layer of less width of more compressible material secured on a surface thereof adjacent the inner edge thereof, preferably within a suitable annular countersink or recess therefor provided therein.

As stated hitherto, a main feature of my invention is to provide a washer or packing member or other means completely covering the surface of the valve seat 40 to protect the valve member 42 from said valve seat and to provide an airand liquid-proof joint therebetween. My invention therefore includes the provision of a suitable washer or packing member which may be cut or fabricated in flat form so as to be bent without any overlap evenly throughout its area into a substantially spherical shape, and for this purpose, as shown in Figs. 1-1l and 19-24, I have provided a washer or packing member 52 constructed of flexible partially compressible material having an annular center portion 52 having a plurality of leaves 65 projecting radially therefrom preferably of the general shape of a fourleaf clover, said leaves having preferably partially convex side walls and being otherwise cut and fabricated so that said washer or packing member, including said center portion and leaves, may be bent into a partially spherical shape with the edges of said leaves 6G substantially abutting without overlap. If desired, the center portion 52 of my improved washer or packing member may be provided with the supplemental layer 6l) of more compressible material secured to a surface thereof adjacent the inner edge thereof, if desired being cemented within an annular countersink or recess 62 therein as shown. If also desired, said leaves 86 or the annular center portion 5.2', if desired, may be provided with the concentric circular grooves 58 throughout either the upper or lower surface thereof characteristic of my invention to permit the leaves or entire washer or packing member to be readily bent into the partially spherical shape shown in Figs. 6 and 17 Without creating the ridges or humps 55.

As stated hitherto, considerable difficulty has been experienced in centering an annular washer or packing member whether it be of the type shown in Figs. 13-17 or of the type shown in the other figures, to have the hole 'l5 thereof .in alignment with the lower nozzle dispensing hole 36, and I may for this purpose provide, if desired, a countersink or recess 54 in the lower portion of the valve seat around said lower dispensing centering purposes, provide the center portion 52 lof said washer or packing member adjacent said hole with an annular skirt 12 projecting axially therefrom to overlappingly seal the edge of the dispensing hole means 36 in the lower portion of said nozzle, which may expose the metal 'i4 of a container coated as at 'l5 extruded or otherwise pressure shaped from a coated blank such as tin coated lead (Fig. 20) and where such a container be provided, exposing the base metal around the edge of said hole 3B as at 75, it is obvious that the skirt shown herein will not only function to center the washer or packing member between the valve seat andvalve closure member but will also function to overlappingly seal the exposed base metal edge l5 of said dispensing hole.

I have shown in Figs. 8-11 a suitable form of apparatus for cutting my improved washer or packing member and assembling said washer or packing member and valve member within the nozzle. The center portion 52 of the improved washer or packing member shown in Fig. 4 is first cut with the central hole 'lll and leaves 56, if employed, in strip form and then may be provided by pressing or otherwise with the annular countersink 62 continuously in strip form and with the concentric grooves 58 either in the annular center portion 52 thereof and/or throughout said leaves `(i6. Asurface of the more compressible supplementall washer layer 6U `may `be coated with a suitable rubber cement 64 and inserted within the countersink 62 or directly to the surface of the center portion 52 thereof if the countersink G2 be not employed. In the embodiment shown, the concentric grooves 58 are preferably pressed, embossed or otherwise formed thereon prior to the washer or packing member 52 being cut out from stock as shown in Fig. 8. The layer of strip material 8|! is fed in continuous strip form over a suitable cutting die 82 provided with a hole S4 therein for the center portion 52 having suitable extensions 86 therein complementary to the leaves 66 in the washer or packing member, and a punch 88 therefor also having suitable projections 81 corresponding to the shape of the flat leaves is inserted downwards through said hole 84 in said die 82 to cut the washer or packing member in the shape shown in Fig. 3 from said strip material 88. A suitable folding die 98 having a hole 92 therein is also provided and the upper end of a nozzle 34, provided with a suitable valve seat 40, is placed underneath said hole 92. A plunger 94, having a head 96 shaped to protrude through the hole 10 in said washer or packing member, is forced downwardly through said hole l0 in said washer or packing member forcing the leaves 66 downwardly through the hole 92 in said folding die 90 and within said nozzle 3|), the leaves 66 being bent upwardly as shown in Fig. 8 into the position shown in Fig. 9, and after insertion through said hole 92, the leaves 66 may expand outwardly so that the top edges thereof abut the lower surface of said folding die 90 exterior of said hole 92 to retain said washer or packing member loosely Within said valve seat. As shown in Fig. l0, a suitable seating die 98 is provided having a at annular lower surface adapted to force and hold the upper edges of the leaves 66 within said valve seat 4U flush with the upper edge 38 of said nozzle, while the plunger member |02 thereof, having the pilot |04 is lowered within the hole |96 therefor in said seating die 98, said plunger also being provided with a partially spherical seating surface |08 beyond said pilot to compactly and evenly seat the washer or packing member within the valve seat 49, the supplemental layer 69, if employed, being simultaneously forced thereby within said countersink 54 where employed and the edges of the washer or packing member leaves 66 substantially abutting each other without overlap to completely cover the surface of said valve seat 40 as shown diagrammatically in Fig. l2. Fig. 11 diagrammatically illustrates the step of inserting the partially spherical valveclosure member 42 within said valve seat 48 after which the edge of the hole 38 in the upper end of said nozzle may be crimped partially over said valve closure member to oscillatably secure it within said Valve seat 48 in accordance with the disclosure in the joint application of Rest and Church, Ser. No. 751,734, heretofore referred to.

It is thus obvious that I have provided a novel type of nozzle closure means for containers and novel types of washers for use therein with the advantages explained above.
