DISPENSING DEVICE Filed July 30, 1963 2 Sheets-Sheet 2 *i INVENTOR.

DONALD E ARMOUR WM ATTORNEYS United States Patent 3,184,732 DISPENSING DEVICE Donald F. Armour, Bloomfieid, Conn, assignor to Monsanto Company, a corporation of Delaware Filed July 30, 1963, Ser. No. 2%,620 11 Claims. (Ci. -594) This invention pertains to improved dispensing devices. In particular, it relates to containers for dispensing materials such as liquids or semifluid solids, which containers are provided with a unique valve mechanism.

The concept of employing a valve mechanism in the outlet of a material reservoir or container is well-known. However, heretofore such valve mechanisms have required a manipulation of components positioned adjacent an exposed material outlet. Thus, where material residue was present on an outlet or on a material applicator positioned on the outlet, a person attempting to manipulate the valve mechanism often inadvertently and undesirably contacted such material.

Container valve mechanisms of the type previously employed have often proven to be nettlesome with respect to the intricacy of their manipulations. In many instances it was diflicult for a user to determine whether or not a valve had been properly positioned and the manipulation of the valve mechanism often proved tedious, frustrating and time consuming in nature.

In recognition of the problems associated with dispenser valve mechanisms of the type previously known, it is an object of this invention to provide an improved dispensing device including a valve mechanism which substantially obviates dimculties of the type heretofore described.

It is a particular object of the invention to provide such an improved dispensing device including a valve mechanism which is automatically operable in response to the securing and releasing of a container outlet closure.

A still further principal object of the invention is to provide an improved dispensing device including functionally interrelated, material outlet, valve, and outlet closure components which cooperate to allow a user to effect the simultaneous securing of the closure and closing of the dispenser valve, as well as the simultaneous releasing of the closure for removal from the outlet and the opening of the valve.

It is an additional object of the invention to provide such interrelated outlet, closure, and valve components which cooperate to insure accurate and positive positioning of a dispenser outlet valve in both open and closed valve positions, responsive only to the securing or freeing of the closure on the dispenser material outlet.

A still further object of the invention is to provide a structural assembly of a container closure, container outlet and outlet valve which is characterized by cylindrically configured components which are coaxially and mutually telescopingly arranged and operably interconnected by appropriate abutment means so as to provide a structure of maximum simplicity, foolproof mode of assembly, and functional reliability.

In order to accomplish the foregoing objects, there is envisioned a dispensing device including a material reservoir which is improved by the addition of a unique combination of material outlet means, valve means, closure means, and valve actuating means. The valve means is associated with the outlet means and adapted to control the exit of material therefrom. The closure means is adapted to be positioned over the outlet means. The valve actuating means is operable between the closure means and the valve means for causing the valve means to open in response to one relative movement between the closure means and outlet means, and for causing the valve means to close in response to another relative movement between the closure means and outlet means. V

ice

In the preferred embodiment, the valve means comprises a rotary valve journaled within a generally cylindrical sleeve extending from the material reservoir which defines the material outlet. The valve actuating means comprises cap-carried abutment means, sleeve-carried abutment means, and rotary valve-carried abutment means. A portion of the cap-carried abutment means is adapted to cooperate with the sleeve-carried abutment means, while another portion of the cap-carried abutment means is adapted to simultaneously cooperate with valvecarried abutment means to cause the simultaneous closing of the valve and securing of the cap on the sleeve when the cap is rotated in one direction. Rotating the cap in the opposite direction is effective to simultaneously open the valve means and free the cap from the sleeve to allow its axial removal therefrom.

In describing the invention, reference will be made to a preferred embodiment illustrated in the accompanying drawings. In these drawings:

FIGURE 13 is a schematic and fragmentary illustration of'valve actuating and closure securing abutment components of the FIGURE 1 device illustrating these components in an open valve position; and

FIGURE 14 is a schematic and fragmentary illustration of valve actuating and closure securing, abutment com comprise a flexible walled bottle fabricated of plastic material, is provided with a material outlet assembly 2. As shown in FIGURES l, 2 and 3, outlet assembly 2 includes material outlet defining sleeve means 3 which has a generally cylindrical configuration. Valve means comprising a rotary valve 4 is journaled, i.e., rotatably mounted, within a cylindrical portion 5 of sleeve 3 in the manner generally shown in FIGURE 3.

Rotary valve 4 has a cylindrical portion 6 having an outer diameter corresponding closely to the inner diameter of the cylindrical portion 5 of the sleeve 3. As shown, valve 4 is coaxially and telescopingly arranged within sleeve portion 5 so as to project partially therefrom. Thus sleeve means 3 and roary valve 4 have a common cylindrical axis (A) as shown in FIGURE 3. The effective securing of the valve 4 within the sleeve portion 5 may be facilitated by an annular bead 7 which projects radially outwardly from the cylindrical, outer periphery of rotary valve '4. Bead 7 is received within an annular groove 8 formed within the inner cylindrical periphery of the sleeve portion *5.

By fabricating the sleeve means 3 of a slightly yieldable plastic material such as polyethylene or polypropylene, the valve head 7 may be moved into engagement with the sleeve groove 8 by merely forcing the rotary valve 4 axially into the cylindrical sleeve portion 5 until the bead enters the groove 8 to lock the valve and sleeve in their journaled relationship. In this relationship, the

I bead 7 may engage the groove 8 to such an extent as to valve 4 but would be facilitated by fabricating the valve 4 of slightly yieldable material.

' Where a material is to be dispensed, such as glue, shoe polish'orother material to be spread on an appropriate surface, it may be desirable to provide a material applicator 9 in association with the valve 4. As shown in FIGURES 2 and 3, such an applicator 9 may comprise a cylindrical segment having a sloping applicator face 10, or other shapes, depending on the product to be dispensedr Applicator 9 may be fabricated of relatively soft, resilientmaterial such as soft solid rubber, sponge rubher, soft solid plastic, soft cellular plastic, or felt.

Applicator 9 may be fabricated so as to be detachable from the valve 4. As illustrated, applicator 9 may be attached to the valve 4 by an annularly grooved neck portion 11 adapted to be peripherally engaged and secured by an annular rim 12 of the valve body 4. Owing to the resilient character of the applicator 9, assembly be- 'Qf this material through a longitudinally or axially extending passagel3 formed inthe applicator 9. Through means of an enlarged passage portion 13a, passage 1 dinally extending passages 17 which communicate with the interior 18 of the material reservoir 1 by way of open interior portion .19 on the lower end of the sleeve means 3.

In the illustrated embodiment, a pair'of longitudinal sleeve passages 17 are provided which are'located on 0pposite sides of the sleeve portion 5. In the manner shown in FIGURES 2 and 3,-each such passagel? may be formed in an outwardly projecting wall portion 17a of the sleeve 3. As shown in FIGURES 2, 3 and 5, the rotary valve-4 may include a pair of lateral ports 16, which are disposed on opposite, sides of the cylindrical valve wall 6 and adapted to be simultaneously aligned with the longitudinal passages 17. As will be apparent, when one port 16 is aligned with onepassage 17, the other valve port will be aligned with the other longitudinal sleeve passage. This inclusion of thetwo ports 16 also permits assembly of the. valve 4 without indexing of the valve.

When the rotary valve body 4 is rotated to. the position shown in FIGURES 3 and 5, so as to, align at least communicates with a relatively enlarged and axially or longitudinally, extending material passage 14 formed in the valve bodyt. The side wall'or cylindrical portion 6 of the valve body 4 is provided withat least one laterally extending port 16; which provides communication between idle and 191). of the abutmentltilh. 70.-

the valve passage 14 and the exterior of the valve body. 7

The lower end of the valve body 2 is closed by a transverse wall 15.

, As shown in FIGURES sand 5, the sleeve means a may-be providedwith one ormore generally longituthe ports 16, with sleeve passages 17,'a material passageway is provided from the interior 18 of the material reservoir 1 to the exterior of the material applicator 9. This passageway includes the sleeve interior portion 19, the longitudinal sleeve passageways 17, the valve ports 16, the valve body passage 14, and-the material applicator passage 13, which opens on the applicator, or material spreading surface. 10.

As will be appreciated, owing to the closely fitting relationship between'the outer cylindrical surface of the valve body 4 and the inner cylindrical surface of the sleeve portion 5, the valve body 4 may be rotated so as todisplacethe ports '16 from the passages 17 and thus close the material passageway by causing portions of the inner surface of thesleeve portion 5 to extend across and seal the ports'l6.

The dispensing device shown in FIGURE 1 includes a closure or cap 29; As illustrated, cap 29 is generally cylindrical in configuration and'includes a cylindrical porsuch asmetal or plastic. As will be apparent by reference to FIGURES l, 2 and 6, for example, cap 2% will have 'a cylindrical axis coincidingwithzthe sleeve means and valve axis (A) when the cap is in its assembled position.

The simultaneous valve actuating and cap securing and releasing action achieved through the present invention is accomplished through the interaction of a series of abutment means carried by the cap 20, the rotary valve 4, and materialoutlet definingsle'eve 3.

Rotary movement of thevalve, responsive to cap movement, is eifected by the interaction of first abutment means abutments 191a and ltlllb disposed, respectively, on 0pposite sides of the interior of the cap 26. Each abutment 101a and 1-9111 projects laterally and generally radially inwardly from theinner cylindrical surface of thecap' portion 21. The first abutment meansineludesifirst surfacev means extending generally. longitudinally, and radially of, the cylindrical axis of the .cap .29 such asthe surfaces 1191c and Mid of. the abutment 101a andthe surfaces The second abutment'meansv comprises a .pairv of gen erally rectangular;'abutinent' portions 162av and 1621). Each suchrectangular abutment portion projects laterally outwardly and generally radially from the outer surface: of the. cylindrical wall 6 of the rotary valve 4. Each such rectangularabutment portion includes second surface means extending generally radially and longitudinally of the cylindrical axis of the rotary valve 4. Included in this second surface means are the surfaces 1020 and 102d carried by the abutment portion 102a and the surfaces 10212 and 102 carried by the abutment portion 102]).

As shown in FIGURE 7, when the cap 20 is positioned over the sleeve 3, with the valve 4 journaled within the sleeve portion 5 and projecting partially thereabove, the abutment portions 101a and 101b are disposed so as to lie in axial alignment with and between the second abutments 102a and 102b,

As shown in FIGURE 7, the circumferential extent of the abutment portions 101a and 101b is sufliciently limited to allow the abutment portions 102a and 10215 to pass at least partially axially thereby so as to position the abutment surfaces of these abutments in at least partially axially overlapping relationship. With this relationship, the surface 102d will lie opposite the surface 101d, the surface 1010 will lie opposite the surface 102f, the surface 101a will lie opposite the surface 102e while the surface 101 will lie opposite the surface 102C.

The securing of the cap 20 on the sleeve 3 so as to prevent its axial movement therefrom is obtained by the cooperation of third and fourth abutment means.

The third abutment means carried by the cap 20 may comprise a pair of abutments 103a and carried by the cylindrical portion 21 of the cap'20. Each abutment 103a and 103b extends generally radially inwardly of the inner surface of the cylindrical portion 21 of the cap 20.

The third abutment means includes third surface means which project laterally inwardly of the inner surface of the cylindrical cap portion 21 and extend transversely of the cylindrical cap axis. Such third surface means include the surfaces 103a and 103d of the abutments 103a and 1031), respectively. As illustrated, these surfaces are disposed so as to face away from the material reservoir 1.

The fourth abutment means, carried by the sleeve means 3, may comprise a pair of abutments 104a and 104b each of which extends generally radially outwardly of the outer surface of the cylindrical sleeve portion 5. The fourth abutment means includes fourth surface means disposed so as to face the material reservoir, which fourth surface means includes the surface 104s of the abutment 104a and the surface 104d of the abutment 10412.

The extent to which the sleeve abutments 104a and 10411 extend circumferentially about the periphery of the sleeve portion 5 is sufiiciently limited so as to allow for the longitudinal passage of the abutments 103a and 103b at least partially thereby when the cap 20 is inserted on the sleeve portion 5. With this relationship, the abutments 103a and 103b may pass between the abutments 104a and 10% as the cap 20 is moved axially over the sleeve portion 5 toward the material reservoir 1 so as to dispose at least a portion of the surface 1030 which lies adjacent the surface 1040 at a point intermediate the adjacent portion of this surface 104a and the material reser voir 1. Similarly, at least a portion of the surface 103d which lies adjacent the surface 104d will be disposed intermediate at least the adjacent portion of the surface 104d and the material reservoir 1. With this arrangement, the cap 20 may be rotated on and relative to the sleeve portion 5 so as to cause the surfaces 103a and 103d tomove respectively 'under the surfaces 104a and 104d so as to secure and prevent axial removal of the cap 20 from the sleeve means 3.

The circumferential overlapping of the surfaces 1030 and 1040 and the surfaces 10% and 103d in and of itself provides an effective cap securing action. However, if

desired, and as shown in FIGURES 13 and 14, the surface 103a and the surface 1040 may be provided with surfaces which slope in complementary relationship and the surfaces 10401 and 103d may be provided with a similar complementary. sloping relationship so as to allow the cap 20, when rotated on the sleeve portion 5 to become wedgingly secured to this'sleeve portion. As will be appreciated, this wedging action requires that the cap be secured against axial movement toward the material reservoir 1 prior to the rotation of the cap. This limitation on axial cap movement may be provided by annular ledge portions or stops 20a and 20b which are adapted to respectively engage the upper surfaces of the abutments 102a and 1021) as illustrated in FIGURE 6.

Limitations on the extent of rotary movement of the valve 4, which will ensure that at one extremity it is in an accurately defined open valve position with the ports 16 and the sleeve passages 17 aligned and that at another extremity it is in a closed valve position with the ports 16 and the sleeve passages 17 out of alignment, is obtained by fifth and sixth abutment means.

The fifth abutment means, carried by the sleeve portion 5, comprises a pair of abutments 105a and 10512, each of which projects longitudinally upwardly from the upper end of the sleeve portion 5. The fifth abutment means includes fifth surface means which extend generally radially and longitudinally of the cylindrical axis of the sleeve 3. Such fifth surface means include the surfaces 105a and 105d carried by the abutment 105a and similar surfaces carried by the abutment 105b.

The sixth abutment means, carried by the rotary valve 4, includes a pair of rectangular abutment portions 106a and 10612 which partially overlap and define integral but offset extensions of the rotary abutment portions 102a and 1022 respectively.

The sixth abutment means includes sixth surface means such as the surfaces 1060 and 106d of the abutment 106a which extend radially and longitudinally of the cylindrical axis of the rotary valve 4 and similar surfaces of the abutment 10611.

With the valve 4 journaled within the sleeve portion 5, the sixth surface means will at least partially overlap the fifth surface means so as to provide rotary stops for limiting the extent of rotary movement of the valve 4. For example, engagement between surfaces 105a and 1060 will properly align the valve ports 16 with the sleeve passages 17 as shown in FIGURE 13, while engagement between the surface 106d and the abutment 1051) will define the extent to which the rotary valve 4 may be moved to a closed valve position as shown in FIGURE 14.

Seventh and eighth surface means may be included in the device so as to afford positive stop means for limiting the extent of axial movement of the valve 4 into the sleeve 5 so as to prevent the inadvertent movement of the valve 4 into the material reservoir 18 during valve installation.

The seventh surface means may comprise sleeve carried surfaces 107a and 107!) each of which extends generally transversely and radially of and partially circumferentially around the cylindrical portion 5 of the sleeve 3.

The eighth surface means extends radially outwardly of the outer surface of the cylindrical portion 5 and partially circumferentially thereabout. The eighth surface means may include a pair of surfaces formed on the lower sides of abutments 106a and 10612. One such surface 108a formed on abutment 106a as illustrated in FIG- URE 13, faces downwardly, i.e. toward the material reservoir 1, and is adapted to engage the upwardly facing surface 107a. As will be appreciated, when the eighth surface means engages the seventh surface means, axial movement of the valve 4 inwardly of the sleeve 5 is positively interrupted or stopped.

As illustrated, the second, sixth and eighth surface means may each include a surface formed on an integral and generally radially outwardly extending projection of a FIGURE-l3, the surface 108:: of the eighth surface.

means is in mutually intersecting relationship with the surfaces 106:: and 106d" of the sixth surface means.

As illustrated, at least one surface of the fifth surface means intersects at leastone surface of the seventh surface means on the upper end of sleeve portion 5. For example, the surface 107a of the seventh surface means is in mutually intersecting relationship with the surface 1050. a Y The cap carried first and third abutment means 101a, 101b, 103a and 10312, cooperate with the valve carried abutment means 102a and 10217 and with the sleeve carried abutment means 104:; and 10412 to effect a simultaneous valve and cap operating action.

The first and second abutment means 161a, lull), 102a and 10212 are disposed in relation to the third and fourth abutment means 103a, 103b, 104a and 1041) so that when the cap 20 is moved axially over the sleeve portion to bring the first surface means opposite or adjacent to the second surface means, the third abutments M311 and 1631) are caused to assume the position illustrated in FIGURES 6, 8, and 13. In the FIGURE 13 position, the abutments 103a and 1031? have moved at least partially past the fourth abutments 104a and 104b. In this position, the valve 4 and sleeve 5 are in the relative positions shown in FIGURES 5, 6 and 13 with the valve in the open or material dispensing position. The abutments 101a and 1011: are positioned between and aligned with the abutments 192a and 16% as shown in FIGURE 7. As shown in FIGURE 8 and FIGURE 13, theabutments 103a and 10312 lie between the abutments 1M1: and 10417 but are axially displaced therefrom. With the apparatus components thus positioned, the cap 20 may be rotated ciockwise, when viewing the device as shown in FIGURES 7 and 8, so as to cause simultaneous valve closing and seem-- ing of the cap 20. This simultaneous action is achieved.

by engagement between the surfaces 101d and ltlZd and the surfaces Idle and 1022 which causes rotation of the valve 4 to a closed valve position as shown in FIGURES 9, 10, and 14, and by the movement of the surfaces 163a and 103d, respectively, beneath the surfaces 1040 and 104d asshown in FIGURES 9, l1, and 14.

When the apparatus components have assumed the closed valveposition illustrated in FIGURES 9, 10, 11,

12 and 14, counterclockwise rotation of the cap 2t? will effect simultaneous reopening of the valve and release of the cap for axial removal from the sleeve 3. As will be appreciated, such counterclockwise rotation of the cap 29 I will cause the surfaces 101c and 101 to respectively engage the valve surfacesltlzf and ltlzc'so as to cause counterclockwise valve rotation and cause the surfaces 1030 and 103d to move counterclockwise to a position displaced from the surfaces 104s and 104d.

With the alignment of abutments shown, if the valve 4 should be rotated to a closed valve position with the cap off, it would not be possible to replace the cap .on the closure in an improper fashion and attempt to secure the cap and rotate the valve. With the valve rotated tothe closed position shown in FIGURE 9, the abutments idea and 104i) Will engagethe abutments 103a and 1&3]: so as to prevent movement of the cap abutments 161a and 10112 3 W317 will ofnecessity engage the abutments 1M: and 16th so as to prevent the abutments 191a and ltilb from moving into operative engagement with thevalve'carried abutments 162a and M9212.

In describing the structure and operation-of theim proved valve mechanism of the invention, the several advantages of the invention have been made apparent.

A valve mechanismhas been provided by means of which simultaneous valve actuation and closure securing and releasing may be achieved responsive to cap manipulation. There is no necessity for a user to engage valve components'adjacent exposed material outlets where there would be a danger of touching material residue.

A valve mechanisnrhas been provided wherein both open and closed valve positions are positively determined merely through the action of releasing or securing a container closure. No tedious manipulations of valve actuatingmembers is thus necessary.

The coaxial arrangement of sleeve, valve and closure components and the unique utilization of abutments integral with these components enables the'production of a functionally effective but structurally simple device. This device includes only three components, each of which may be conveniently fabricated by conventional molding techniques. The arrangement of abutments on the components is such as to positively prevent improper assembly of I the cap, valve and sleeve components.

into'the spaces ,between the abutment portions 102a and r 102k. This-safety feature vwhich insures a foolproof mode of assembly of components.results'from the relative positioningof component abutments. When the valve 4 has been rotated to the closed valve position the abutments 102a and 10212 are generally alignedwith the abutments 104a 'and 10412, respectively, asshown in FIGURES 9,' 10, 11, and 14 As shown in FIGURES .9, 10, and 11,

the cap carried abutments lime-and 16935 are circumferentially offset from the cap carried abutments 101a and liilb and are disposed between the abutments 101a and 1131b and the material reservoir. 1." With this arrange ment of'cap abutments, and when the valve is in the closed position shown in FIGURE 14, the abutments 103a and While the invention has been described with reference to a preferred embodiment, it will be readily apparent that its scope is such as to encompass additions, modifications, deletions, substitutions, and other changesin relationto the illustrated form of the invention.
