Arplicanonliebruerrll, 1.951@ Serial No. Y2.194576 s claims. (o1. gaz- 363) The invention relates to dispensing devices lncorporated with containers for particulate objects for obtaining a release or discharge of bjects vfrom the container in one at a time order or in measured numbers, and relates more particularly to container cap constructions embodying such dispensing mechanisms and which are adapted for attachment to conventional type containers.
An object of the present invention is to provide a dispensing .device Vof the character described which may be quickly and easily attached to conventional type bottle containers and which will afford an improved dSperlSing of particulate objects therefrom in one. at a time order or in measured quantities ,a precise. easily operated and foolproof manner.
Another object of the invention is to provide a dispensing device of .the `character lalcove Which may be used for the dispensing of bait eggs which, due to their generally mucilaginous nature have proven to be diiiicult to handle in a dispensing device of the present character, As a feature of the present construction. bait eggs or the like may be elciently dispensed in One at a time order without injury or mutilation of the eggs and without danger of spillingnumbers of eggs from the container..
A further object oi the present invention is to provide .a device of the character described in which the dispensing passages are internally contained and .the final discharge passage generally covered, whereby the, device will remain clean and sanitary in use and be resistant to clogging or other entry of .dirt or other metter into the dispensinepassages.
Still another object .0f the invention is to pro-,- vide a device of the character described which is composed of a minimum number of sturdily constructed parts affording a compact and light weight unit adapted Afor rapid and economical mass production which the parts may be quickly and easily disassembled ,for cleaning when de,- sired and which, .when disassembled, will .aord direct access to all openings and passages for easy cleaning.
The invention possesses other objects and features of advantage, Some Q f Y which, with the foregoing, will be set forth in the following de,- scription of the preferred form of the invention which is illustrated in the drawingaccompanying and forming part of the specification. It is une derstood, however, that Variations in the showing made by said drawing .and description may be adopted within .the scope-0f the invention Yasset forth in the claims.y

Figure 2 is a plan view of the device illustrated in Figure 1l Figure 3 is a cross-sectional View of the dispensing device and part of vthe assooiatedcontainer in inverted position.
Figure i is a cross-sectional view similar to Figure 3 but showing the parts in a inal dissensing Position.-
The dispensing device ofthe present invention and as illustrated in the accompanying drawin g is 'here incorporated in a Yunitary and selfcontained cap construction 6 adapted for attachment to a conventional type bottle container l. The unit consists briey of a generally cupshaped cap o r body section 8 adapted for attachment to the open end portion of the container, and a relatively movable cover plate i) cooperating therewith and rproviding upon appropriate displacement a one at a time discharge of objects stored the container.' The cap or body section hereincludes a depending skirt il formed to embrace the end portion l2 of the lbottle container l adjacent the .open end face I3 yof the container, and a solid end wall section lll which is integrally formed with the skirt Il and is arranged `to seat upon and extend across the end face I3 to provide a closure for 4the container. In order to t the usual bottle container, the skirt Il is preferablyof annular form internally threaded to engage and `mate with threads cus.- tomarily provided -on the` outer periphery of the bottle portion I2.
As anrimportan-t feature of the present invention; the .end section i4 of the cap is provided with a smooth, planar exterior face IB upon which is seated for sliding movementa similarly formed smooth, planar interior face vIl of the cover plate 9,'and the coacting passages for effectinga one at a time 'discharge of objects from the container lare incorporatedbetween these sliding lfaces,
wherebysuch passages are concealed Within the unit kand constantly protected from the entry of `dirt or other matter. Any suitable means may `be used rfor retaining the faces lli and lll in sliding .operative contact to provide the rela.- tive movement between ythe closure 'plate .and can section as .above .noted- Cionreniently, both of vthese parte may be made voi oir, iler iorm and seen-red together in concentric att. Climent for relative rotation of the .Cover plate by means .oi a center pivotingand securing `H lenliter lewall thickness of the cover plate to aeseve As here shown, these members may consist simply of a threaded bolt mounted through aligned center openings in the plate and cap end, the bolt being here arranged with its head I9 countersunk in the exterior face 2i of the plate and with a nut 22 secured on the inner end of the bolt and bearing against the interior face 23 of the end wall i4. The countersinking of the head I9 provides a flush and smooth construction at the outer face 2l and, if desired, the nut 22 may be of a self-locking construction to hold the plates in proper engagement and against loosening in normal use.
Exit of objects, here generaly denoted by A, from the container is effected through a port or opening 24 through the end wall I4 interiorlyvof and preferably adjacent to the skirt Il so as to pass objects from the interior of the container to the confronting face I1 of the cover plate 9. Provided within the face I1 is a. recess 26 located radially from the member I8 by the same distance as the opening 2d so that, upon appropriate rotation of the cover plate 9, as illustrated in Figure 3, the recess will register with the opening 24. The size and depth of the recess, as illustrated, is predetermined so as to contain but one of the objects A to be dispensed or, if desired, this recess may be enlarged to contain a definite number of such objects. Discharge of the object from the recess 26 is effected -by another passage 21 (see Figures 2 and 4) provided in the end wall I4 in circumferentially spaced relation to the opening 24 whereby, upon appropriate rotation of the cover plate, the object in the recess 26 will be carried to the passage 21. The latter passage opens to the face I6 at a radial distance from the center member I8 the same as the radial positioning of opening 24 and recess 26, so that upon rotation of the cover plate to the position illustrated in Figure 4 the passage 21 will register with thhe recess 2E for receipt of an object therefrom. The passage 21 is arranged of sufficient size at the recess 26 to serve this purpose, and extends outwardly, in a generally radial direction, to the outer periphery 28 of the cap end wall for discharge of the object. Preferably, and as here shown, the passage 21 is formed as a -radial groove in the end face I6 of the cap end wall and which is covered by the confronting nterior face I1 of the cover plate to provide a closed side for the passage. In this manner all of the passages are fully internally contained and concealed with the exception of the outer end of passage 21, and such end is arranged at the side of the unit where it is normally protected. In order to provide the passage 21 Within the end wall I4 While keeping the end Wall to a minimum Wall thickness, we prefer to arrange the passage within a boss 29 formed in the end Wall I4 at the interior side thereof. The boss 29 is here formed inwardly with an annular shoulder 3l which provides the seating area for the cap section on the end face i3 of the container.
Rotation of the cover plate to effect the discharge of objects as above described is here conveniently effected by a knob 32 formed as an out- Wardly projecting boss on the external surface 2I of the plate. As a feature of the present construction this knob is positioned on the plate at a radial distance lining up with the opening 24, and the recess 26 may thus be provided in part within the interior of the knob as illustrated in Figures 3 and 4. In this manner an adequate size recess 26 may be retained While keeping the a minimum.
Positioning of the knob radially as described, locates the knob adjacent the outer periphery of the unit Where it may be most conveniently engaged by one of the fingers of the hand holding the unit, thus enabling a one-handed operation where desired.
Since the several openings and passages are internally arranged, it is highly desirable to provide appropriate stop means for the rotation of the end plate so as to define terminal positions which will precisely align and register the passages 24 and 21 with the travelling compartment or recess 26. This is effected, as here shown, by the provision in the end face I6 of the cap section of an arcuate slot or recess 33 concentric to the pivot pin I8 and in which is mounted a pin 34 carried by the cover plate, the circumferential length of the slot 33 being such that the pin 34 will abut the opposite'circumferential ends 36 and 31 of the slot 33 in the two terminal positions of the cover plate above noted and illustrated in Figures 3 and 4. It will be seen that the provision of the slot 33 and pin 34 at the confronting faces I6 and I1 of the cap and cover plate effect a complete concealment of the stop means within the interior of the unit.
As a further feature of the unit, We prefer to construct the cap section and cover plate of a. transparent plastic material which aords several important operating features. Such construction permits a viewing of the operation of the device so that the user can readily see the entry of an object into the travelling compartment 26 when thhe parts are aligned as illustrated in Figure 3, prior to rotation of the cover plate to discharging position as illustrated in Figure 4. By forming the parts of plastic, they may be readily moulded to effect a high speed, low cost mass production of the unit. Also, with such material the obtaining of smooth, polished surfaces for the confronting faces I6 and I1 is likewise aorded, so that an excellent sealing of the unit is obtained, While at the same time an easy gliding action of the end plate across the outer face of the cap section is afforded.
Preferably the bolt I8 and its lock nut 22 are constructed of suitable corrosion resistant material such as stainless steel, aluminum or the like, so that with the plastic construction above described all of the parts of the unit will be well adapted for use with various objects to be dispensed. As will be noted from the foregoing, the device may 'be quickly and readily disassembled for cleaning by loosening the bolt, when the cover plate may be removed from the cap section to fully expose for easy brushing or other cleaning all of the openings, recesses and the like.
In the use of the present device, the usual threaded cap will be removed from the container 'I and in its stead the cap section of the present unit threaded into place on the bottle to tightly seat the cap shoulder 3I onto the end face I3 of the container. To facilitate this attachment and to remove possible straining on the stop pin 34 of the cover plate, the cover plate is preferably formed of a slightly smaller diameter than the cap section so that only the latter will be normally manually gripped in effecting attachment to the container. To remove the object from the container, the cover plate is rotated to its terminal position illustrated in Figure 3, that is, With the stop pin 34 in abutment with the slot end 31. The container is inverted as shown in Figure 3 in order to pass the object through opening 24 and into the travelling compartment 26. Where the bottle contains objects of a. muellaginous character, or where the objects otherwise tend to stick together, an object may be loosened to fall into the compartment by appropriate shaking of the container. The cover plate is then rotated to its other terminal position as illustrated in Figure 4, that is, with the stop pin 34 in abutment with the slot end t6 andthe container turned to a sidewise position as illustrated with the passage 2'! extending downwardly, when the object will pass from the recess 26 into the passage 2? for discharge from the underside of the unit and into the hand of the user. The device in this manner functions in an eiiicient, precise and foolproof fashion to remove the objects in one at a time order and may, if desired, be held and completely operated in and by one hand only of the user.
While the device of the present invention has been illustrated and described as a unitary attachment to existing bottle type containers, it will be understood that the device may be directly incorporated in and as a part of a container while retaining the essential features of the invention.
