BUBBLING AMUSEMENT DEVICES 4 Sheets-Sheet 4 Jan. 8, 1963 Filed July 27, 1962 has United States Patent Ofifice 3,071,888 Patented Jan. 8, 1963 The present invention relates to an amusement container device featuring an observable body of liquid caused alternately to disappear and reappear, or at least change position in the device with attendant alteration of appearance, upon manipulation of the device.

This application is a continuation-in-part of application Serial No. 133,675, filed August 24, 1961, and now abandoned.

According to the invention there is provided a container device which, for purposes of amusement, simulates repeated emptying of a compartment thereof having lighttransmitting exterior walls for observation of liquid contents. There is provided a liquid-tight and alternately invertible, elongated hollow container having opposite closed ends and at least an intervening pair of tandem sections with one of the latter constituting a top end section and the other a lower section therebeneath in an upright position of the container. Transverse partition means are mounted within the container to define at least a part of the interior thereof into segregated supply and receiving chambers. The receiving chamber occupies the top end section and in some embodiments of the invention the walls thereof are of a character substantially to block transmission of light rays therethrough, such as by being opaque, so as to hide the liquid when transferred into the receiving chamber. A body of gaseous medium, such as air, is trapped in the receiving chamber. The supply chamber of the various embodiments of the invention is exteriorly defined in part by light-transmitting side walls, such as by being transparent or translucent, to permit observation of a body of liquid therein,

and it occupies the container section beneath the receiving chamber. This supply chamber section has an interior side wall structure spaced inwardly from the light-transmitting side walls to define therebetween the supply chamber in the form of a circumscribing space of relatively small transverse dimension to limit the volumetric capacity of the supply chamber. The volumetric capacity of the receiving chamber at least approaches that of the supply chamber so that it may accommodate at least a major portion of the liquid contents of the latter. The transverse partition means includes gravity-operated valve means having a controlled flow passage or valve port extending past the partition means to allow transfer of the liquid from the receiving chamber to the observable supply chamber. The valve port is of appreciable flow area to permit relatively rapid flow of the liquid therethrough. The valve means is biased by the force of gravity to open position of the valve port in theupright position'of the container to permit the relatively rapid return liquid flow through the port. When the container is inverted the valve means is gravity biased to a position of substantial closure of the valve port to limit or prevent flow of the liquid through the'latter from the supply chamber, which is now uppermost, down to the receiving chamber. The transverse partition means also provides a plurality of small trickle passages eccentrically located with respect to the center thereof at angularly spaced points, thereby communicating the supply chamher to the receiving chamber in an inverted position of the container. When the container is inverted to a position which places at least one of thettricklepassages at an elevation lower than another thereof the liquid will trickle down through the former to the receiving chamber with simultaneous countercurrent bubbling transfer of the trapped gaseous medium back up into the slowly 2 emptying supply chamber. This bubbling action is of importance to the observer since it has visual appeal and is associated with conventional depletion or delivery of liquid contents of many familiar devices that the present apparatus in many of its forms may simulate or represent in toy form. The rapid return of the liquid, which may be hidden in the receiving chamber, back to the supply chamber for another cycle of delivery operation has ap-' peal to the observer since it eliminates tedious waiting for trickle return before the intriguing trickling and hubbling delivery can be repeated.

It is thus an object of the present invention to provide the amusement device of the present invention in forms which will intriguingly simulate the general appearance and those characteristics of the action of conventional delivery of liquid contents having considerable visual appeal of various devices familiar to many people, and' particularly children.

Another object of the invention is to provide the amuse, ment device in a miniature form simulating a milk feeding bottle for infants so that a child may mimic with a doll the feeding of milk in the conventional manner of' ing with its own separate supply chamber isolated from a second supply chamber communicating only with theother receiving chamber and with the supply chambers being in the form of annular spaces telescoped one within another by light-transmitting walls so that bubbling action in either may be observed from the outside. In embodiments of the amusement device having such telescoped supply chambers the supply liquids may be translucent liquids of different colors to give unique color efiects.

Other objects of the invention will in part be obvious and will in part appear hereinafter. 1

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.

Referring to FIGS. 1 to 9 incl., there is shown a toy bottle 20 intended for simulated feeding of milk to a doll, having a cylindrical transparent plastic or glass hollow body 22. The body is formed with a hollow filler body, which may be in the form of a reentrant cylindrical section 24 defining an annular compartment or chamber 25 between the section 24 and body 22. This compartment is substantially filled with a white or colored liquid 26. The reentrant section 24 has a closing flat top end 28 in the upper portion of compartment 25, and a movable disc 30 whose diameter is slightly less than the inner diameter of body 22 rests loosely thereon. The disc has a notch 32 in its circumferential edge (see FIG. but preferably is provided with a plurality thereof at circumferentially spaced points.

A cylindrical ring 34 is formed with a skirt 36 to telescope or fit into the open end of body 22. The inner diameter of the skirt 36 is less than disc 30 so that the disc lies on the skirt when the bottle is inverted as shown in FIG. 5. The radially inward tip end of notch 32 then provides a restricted opening providing communication between supply compartment or chamber 25 and a receiving compartment or chamber 40 of a hollow opaque neck 42 extending outwardly of ring 34. The neck has a closed tubular end 44 formed to simulate a nipple of a babys bottle. The neck has an annular external flange 46 which engages within radially extending internal flange 48 at the outer end of the ring 34.

FIGS. 2, 3 and 6 illustrate best the mode of operation of the toy bottle embodiment 20. In FIG. 2 the bottle device 20 is shown upright. The liquid 26 substantially fills compartment 25 and is visible through the transparent body 22. The liquid appears to fill the entire bottle since the presence of inner section 24 is not apparent to the viewer. This is particularly true if the plastic walls are translucent having, for example, a milky appearance characteristic of conventional polyethylenes.

FIG. 6 shows the toy bottle 20 inverted and tilted. The liquid 26 is shown flowing at a restricted rate through the radially inward, uncovered tip portion of notch 32 from compartment 25 to compartment 40. FIG. 3 shows the bottle fully inverted. All the liquid 26 has drained into the compartment 40 of the neck and the body 22 appears empty. When the bottle is placed upright to the position of FIG. 2 from the position of FIG. 3, the valving disc 30 drops down upon the closing top end 28 of filler section 24 and the liquid will flow quite rapidly past the circumferential edge of the valving disc from the neck chamber 40 back (into the compartment or chamber 25 again.

FIGS. 16 to 18 incl. show a display assembly 50 which may be used for cyclically tilting or inverting the bottle device 20 and then swinging it back to an upright position. A vertical board or panel 52 has a horizontal base 54. On the base is a motor 56 energized by a cable 58 terminating in a plug 60 which can be connected to a convenient power outlet. A belt 62 is entrained on a pulley 64 carried by shaft 66 of the motor and on a pulley 68 carried on another shaft 70 journaled for rotation in a bearing 72 on the panel 52. A sector gear 74 is retatable on shaft 70. Another shaft 76 carries a spur gear 78 behind the panel 52. A spring clamp 80 is connected to shaft 76 and rotates therewith. The clamp holds bottle 20. A part of a dolls head 82 is secured to the front of the panel and has a mouth 84 disposed so that when the bottle is tilted as shown in FIG. 16, the nipple end 44 is located at the mouth 84. A stop pin 85 extends outwardly of the panel below shaft 76 and clamp 80 to limit rotational movement of the bottle during operation of the display assembly.

In operation of the display assembly, the gear 74 is rotated continuously. In FIG. 17, the

gears

74 and 78 are disengaged. The bottle is supported by clamp 80 near the bottom of the bottle so that the bottle is downwardly inclined resting on pin 85 with nipple end 44 at the dolls mouth 84. As the gear 74 rotates it engages the gear 78 and rotates the shaft 76 to an upright unbalanced position P of the bottle device 20, as shown by dot-dash lines in FIGS. 16 and 17. The supply compartment 25 then fills rapidly with liquid 26 from the neck receiving compartment 40. As the gear 74 continues rotation, the

gears

74 and 78 disengage and the bottle device 20 swings by force of gravity down to the inverted tilted position P', shown in dash lines in FIG. 17 and full lines in FIGS. 16 and 18. The liquid in supply compartment 25 then drains slowly out of the body 22 into the receiving chamber 40 of neck 42. The rotation of gear 74 is so timed that the bottle device 20 is placed in the unbalanced upright position P when substantially all of the liquid is drained into the neck chamber 40, whereupon the supply compartment 25 is refilled rapidly. Thereafter, the gear 74 disengages from gear 78 and permits the bottle device 20 to be rotated to the draining, tilted position P. The operation proceeds cyclically and continuously and the doll appears to be drinking milk from the simulated feeding bottle 20 in an interesting and amusing display, for advertising purposes or the like.

In FIGS. 10 and 11 is shown another bottle embodiment 20 having a hollow neck 42 which is provided with a foil label 43 to render the neck opaque. The bottle device 20 resembles a beverage bottle with a long neck 42*. A further label 45 having indicia 47 thereon secured to body 22 may suggest that the contents of the bottle is a certain beverage. The liquid 26 in the annular compartment 25 of transparent cylindrical body 22 may be colored to simulate the conventional color of the beverage it imitates. Neck 42 has a closed end 44. Other parts of bottle embodiment 20 corresponding to those of bottle device 20 are similarly numbered. The valving arrangement of FIGS. 11 and 12. provides for rapid refilling of supply chamber 25 from receiving chamber 40. The hollow neck 42 is closed at the bottom by a transverse partition, in the form of a depending central plug 41 fitted into a central opening 51 in the top of the body 22 The plug 41 is provided in its bottom end with a socket 53 which communicates at its top with neck chamber 40 by way of a circular valve port 61. The bottom circular edge of valve port 61 serves as a valve seat and the side walls of socket 53 serve as a valve cage. The bottle 20 has a valve ball 55 provided with crossed

diametral passages

57 and 59 loosely mounted in valve cage socket 53 and resting on filler member top wall 28. This ball clears the valve port or opening 61 in the bottom of the neck 42 and the valve seat defined thereby to provide a wide annular passage 63 for passing or spilling liquid 2.6 from the neck receiving compartment 40 back down to the body supply compartment 25 when the valve ball 55 rests on the transverse top wall 28 of the filler section 24 When the bottle 20 is inverted, valve port 61 is closed by the valve ball 55, and the liquid flows at a restricted rate through the

passages

57 and 59 in the ball into the top end of supply chamber 25.

FIGS. 13 to 15 incl. show another bottle assembly 20 which may be used for a soda bottle display. An opaque label 71 on the long hollow neck 42 conceals the liquid which is collected in the neck chamber when the bottle device 20 is inverted. Loose disc 30 is employed as a valve element to control liquid flow as explained in connection with bottle device 20. Other parts of the bottle assembly corresponding to those of the other bottles previously described are similarly numbered.

In the FIGS. 13 to 15 incl. embodiment the valving disc 30 is shown provided with a plurality of edge notches 32, which may be four in number located at quarter points. The notched valve disc 30 seats loosely into the top end of tubular light-transmitting or translucent body 22, resting upon the top transverse wall 28 of filler member 24. The bottom of the hollow neck 42 is mounted upon a connecting ring 34 that has a depending circular flange 36 which is then telescoped down into the top end of tubular body 22 above valve disc 30 but terminating appreciably short of the latter to permit some axial motion of disc when the bottle device 20 is swung to an inverted position and then reinverted to an upright position. The valve disc 30 is of a diameter appreciably less than the internal diameter of the tubular body 22, so that liquid 26 may spill about its periphery (as well as through the full area of notches 32) down from the neck receiving chamber 40 to supply annular space 25. The depending flange 36 is of less internal diameter than the outer diameter of valve disc 30 to provide a ported valve seat for the latter in an inverted position of the bottle device 20, as will be seen from FIG. 14 and 15. The inner tip ends 32 of the notches 32 in'the valve disc 30 extend inwardly to a circle of a diameter slightly less than the internal diameter of the depending flange 36 to provide small passages past the valve seat communicating the supply chamber 25 to the receiving chamber 40 in an inverted position of the bottle device 20. In an annular marginal zone of thevalve disc a plurality of pin holes may be substituted for the notches 32 at the locations of the exposed inner tips 32 of the latter, or radially inward thereof. 7

As will be understood from FIG. 15, when the embodiment of FIGS. 13 to 15 incl. is inverted, buttilted from a true vertical position, the transverse partition constituted by valve plate or disc30 and its valve seat provided by the lower end of the depending flange 36, which separates the annular supply-chamber 25 from the receiving chamber 40, will permit trickle transfer of the liquid 26 from the former to the latter. If such an embodiment of the device, which has a transverse subdividing partition extending normal to the longitudinal axis of the container is inverted to a true vertical position, the trickle passages provided by the inner tips 32 of the notches 32, or equivalent pin holes, will all be located at the same elevation. The relatively small cross-sectional areas of the trickle passages, the viscosity of the liquid and the location of the trickle passage in the same horizontal plane which places on each the same head of liquid will prevent transfer of liquid in any appreciable amount therethrough from the uppermost annular supply chamber to the lowermost receiving chamber. However, when such an embodiment of the amusement container device of the present invention is tilted slightly from the vertical inverted position such partition means 'is oriented to an oblique position wherein at least one of the trickle passages is located at a higher elevation than the one which is disposed on the diametrically opposite side thereof, thus providing a less liquid head on the former than on the latter. Consequently, liquid will trickle through the lower trickle passage to the receiving chamber with accompanying countercurrent bubbling transfer of air from the former up into the annular supply chamber. Thi action is illustrated in FIG. 15, wherein it will be seen that the trickle passage 32 at the left side is at a lower elevation than the similar trickle passage on the diametrically opposite side of valve disc 3 0, so as to cause liquid contents 26 in annular supply chamber 25 to drip or trickle down, as is indicated at 65, through the former trickle passage into the receiving chamber 40 with simultaneous countercurrent transfer of air up from the latter through the higher trickle passage in the form of a series of bubbles 67. The bubbling effect has appreciable visual appeal not only because of the observable bubbling action, but also since it simulates actual operation of devices which embodiments of the present invention imitate. For example, the withdrawal of milk contents of a feeding bottle by an infant is accompanied by a transfer of replacement air through the nipple aperture into the bottle chamber in the form of a series of bubbles. Bubbling action of embodiments of the device of the pres ent invention will simulate this bubbling action. In forms which simulate containers of carbonated beverages one not only expects to see through a light-transmitting container or transparent glass bottle bubbles which attend flow of the carbonated beverage therefrom, but also bubbles which accompany shift of the liquid contents due to release of the carbonating gas from the liquid. The bubbling action which is attainable by operation of embodiments of the present device will satisfy the expectancy and enhance the value of such amusement embodiments or displays which employ them.

It will-be understood from the description above of the operation of the F168. 1 to 9 incl. embodiment that upon reinversion of the bottle device 20 of the embodiment of FIGS. 13 to 15 incl., the valve disc 30 drops down to rest upon the transverse top wall 28 of the filler structure 24, so that the valve port defined by the bore of the depending flange 3 6 is wide open and the liquid 26 flows freely and quickly from the concealed receiving chamber 40 back into the annular supply chamber 25', between the peripheral edge of the valve disc and the inner wall of the tubular body'22, as well as through the wide open notches 32, so as rapidly to recondition the device for the next cycle of trickle transfer and bubbling action operation.

. The embodiment of the invent-ion shown in FIGS. 19 to 22 incl. is in the form of a toy bottle simulating a nursing bottle for feeding milk to an infant. Container. of this embodiment includes a cylindrical-cup-shaped shell 91 of light-transmitting plastic having a tubular side wall 92 closed 011 at the bottom by a transverse closing wall 93, and provided before assembly with other parts of the device with open month end 94 terminating in a circular lip 95. Near the transverse closing bottom wall 93 the bore of the shell 91 is stepped to provide an internal annular shoulder 96.

A pair of like spacer plates or spiders 97 are inserted into the interior of the shell '91. Each spacer plate or spider 97 is in the form of a disc 98 having a plurality of radial arms 99 extending therefrom and preferably located at a relatively few equally-spaced circumferential points to define therebetween relatively large intervening flow notches 100, as shown in FIG. 21. The disc 98 of each spacer plate or spider 97 is provided with a concentric land 101 to define thereabout a rabbeted annular shoulder 102, and with these spiders mounted in relatively reversed positions so that the annular shoulders 102 thereof are arranged in opposed or facing relation. A section of plastic tubing 103 is mounted between the spiders 97 and has a bore of an internal diameter about equal to the diameter of the circular lands 101, so as to receive the latter in opposite ends thereof with a tight fit. The ends of the tubing section 103 rest upon and are suitably sealed in a fluid-tight manner to the opposed annular shoulders 102. Consequently, the interior of the subassembly of the two spiders 97 and the tubing section 103 defines a closed hollow space and this structure merely serves as a filler body to reduce the fluid capacity of the interior of the shell 91. As a result, an annular supply chamber 104 is defined between the tubing section 103 and the cylindrical side wall 92 of the shell 91 and communicates through the notches 100 with the space 105 between the shell bottom 93 and the disc 98 of the bottom spider 97 so that the latter forms a part of the supply chamber. The notches 100 of the top spider 97 communicates the top end of this supply chamber with a space 106 in the top end of the shell 91.

A transverse partition or wall 107 is provided in the form of a circular plate, having its circumferential edge 108 seated upon the top end 95 of the shell 91, as is shown in FIG. 19. The circumferential edge 108 of the partition plate 107 (details of which are shown in FIG. 21) is provided with a plurality of notches 109 located preferably at equally spaced circumferential points, with the inner tip end 110 of each notch arranged on a circle of a diameter slightly less than the internal diameter of the top end 94 of the shell 91, so as to provide thereat a plurality of small flow or trickle passage which may have a flow capacity about equal to that of pin holes made by conventional common pins which may be about 0.025" in diameter or slightly larger, depending upon the viscosity of the liquid which is to trickle therethrough. The partition plate 107 is provided with a relatively large flow passage in the form of a valve port 111 located cen trally therein with the bottom edge thereof serving as a valve seat 112. The bottom face of the partition plate 107 preferably is provided with an annular series of depending legs 113 having their bottom ends 114 resting upon the top face of the top spider 97, so that when this partition plate has its circumferential edge 108 resting upon the lip 95 of the shell 91 these depending legs will securely hold in position the filler sub-assembly consisting of the tubing section 103 and the pair of spiders 97, with this sub-assembly seated upon the annular shell shoulder 96.

The top end of the container '90 preferably is in the form of a hollow air-filled hood or cap 115, preferably in a shape simulating the capping nipple of a nursing or infant feeding bottle. The bottom edge of the cap 115 is counter-bored to define an interior annular shoulder 116 and a depending annular flange 117, with the latter telescoped down over the top end 94 of the shell 91 and sealed thereto in a fluid-tight manner, such as by cement. In this mounted position the annular shoulder 116 abuts the top side of the circumferential edge 108 of the partition plate 107, thereby holding all of the previously described parts in their relative positions. The cap 115 and the partition plate 107 together define a receiving chamber 118 which is communicated to the supply chamber 104 and its top space 106 both by way of the valve port 111 and the plurality of trickle passages 110.

A valve ball 119 is loosely held captive in acage defined by the annular series of depending legs 113, beneath the valve seat 112 and resting upon the top face of the top spider disc 98, so as to provide a relatively large valve port opening for rapid return liquid flow from the receiving chamber 118 to the supply chamber 104.

When the embodiment of the amusement container device of FIGS. 19 to 22 incl. is inverted to a tilted upside down position, as depicted in FIG. 22, with one or more of the small flow passages to one lateral side of the center of the partition plate 107 at an elevation lower than one or others of the small flow passages on the opposite lateral side thereof, the valve ball 119 will drop and engage the circular valve seat 112 to close the valve port 111. The lower small passage or passages 110 Will permit liquid 26 to trickle down therethrough from the supply chamber 104 and its head space 106 into the receiving chamber 118, as is indicated at 120, with simultaneous countercurrent flow or transfer of air in the latter back up through the higher small passage or passages 110, in the form of bubbles 121 rising in the liquid 26 remaining in the supply chamber toward the space above the surface of this liquid adjacent the closing cross-wall 93 or area 105. When the cap is molded from opaque plastic this trickling liquid 26 appears to disappear as it collects in the inverted receiving chamber 113. The rising bubbles 121 are readily observable through the light-transmitting side wall 92 of the shell 91, which may be molded from either transparent plastic or translucent plastic that may have a milky appearance. The rising bubbles 121 which successively travel longitudinally between the tubing section 103 and the light-transmitting shell wall 92 will be readily apparent through the latter to provide the desirable bubbling action which simulates rising bubbles in an infants feeding bottle as milk is withdrawn therefrom during feeding.

It is important that the empty filler sub-assemhly of the tubing section 103 and spiders 97 be employed so that the cubic capacity of the supply chamber 104 and the hidden receiving chamber 118 approach equality to permit the latter to receive at least ahnost all of the milky liquid 26 in the supply chamber while maintaining the main container portion and the nipple simulating cap 115 in relative proportions of an actual infants feeding bottle. Also, by defining the main portion of the supply chamber 104 as an annular space the rising bubbles 121 are caused to travel adjacent the inner surface of the shell Wall 92 so as to be as apparent as possible for maximum observable action. The radial width of the annular space of the supply chamber 104 and the size of the bubbles 121 will determine Whether the latter will flatten out between the exterior wall of the filler tubing section 103 and the shell side Wall 92 to bridge completely thereacross and form circular windows. In certain embodiments it may be desirable to form the filler tubing section 103 from colored plastic material, so that the color thereof may be observed through such circular bubble windows and the outer light-transmitting shell side wall 92, as will appear hereinafter.

A further embodiment of the invention may employ a pair of separate receiving chambers with a single supply chamber annular space, so that the latter may alternately supply the liquid first to one of these receiving chambers and then to the other thereof as the container is inverted and then reinverted. Such a structure is shown by way of example in FIGS. 23 and 24 in the form of a timer device 125. The amusement device 125 consists of a tubular shell 126 closed off at opposite ends by caps 127 having fiat ends upon which the device may rest alternately in an upright position. The tubular shell 126 and the closing caps 127 together define a liquidtight and alternately invertible, hollow container having opposite closed end sections 123. The tubular shell 126 is formed from light-transmitting plastic, which may be transparent or translucent, so that at least the midsection 129 thereof, between the end sections 128 of the container, can be looked through for observation of liquid contents 26.

An interior side wall structure defines a filler body 130 telescoped within the mid-section 129 of the container, and it is spaced inwardly from the light-transmitting side wall of the latter to define therebetween a supply chamber 131 in the form of a circumscribing space 131. A pair of similar transverse partition means 132 are inserted in the tubular shell 126 to define or separate the mid-section 129 from the end sections 128. For this purpose, a tubular spacer sleeve 133 is inserted into each end of the tubular shell 126 to define an inner annular shoulder 134 against which the circumferential edge of one of the transverse partition means 132, preferably in the form of a plate, seats. Each of the end sections 128 is hollow to define therein, or within the tubular spacer sleeve 133 telescoped therein, a receiving chamber 134.

Each tubular spacer sleeve 133 may be made of opaque plastic so that the side Walls of the receiving chamber 134 therein will be opaqued, so as to hide the receiving chambers. The annular space 131, which is to serve as a supply chamber, is thus separated from the pair of receiving chambers 134 by the pair of transverse partition plates 132, and the cubic capacity of each of the receiving chambers preferably at least approaches that of the supply chamber, so that a body of liquid in the latter may be transferred almost wholly or entirely there from into either of the receiving chambers. The tubular shell 126 may be the cylindrical for conventience of construction, which also permits tubular spacer sleeves 133 to be cylindrical, and in such event the filler body 130 may likewise be cylindrical so as to define the supply chamber 131 as an annular space.

It has been made apparent from preceding descriptions of other embodiments, and as will be further indicated hereinafter, trickle passages provided by transverse partition means require that the container be so oriented as to locate one on one lateral side lower than another on the other lateral side, for countercurrent transfer of liquid from the supply chamber through the former and bubbling transfer of air from the receiving chamber therebeneath up to the supply chamber. For this purpose, the device shown in FIGS. 23 and 24 may orient each of the transverse partition plates 132 obliquely, as shown. This may be readily attained by locating the inner end of each of the tubular spacer sleeves 133 on a plane arranged obliquely to the longitudinal axis of the container device 125. Thus, each transverse partition plate 132 will be elliptical in shape, and the circumferential edge thereof may have a fluid-tight seal with the inner cylindrical wall of the tubular shell 126 by any suitable means, which may be readily attained by forming each of the partition plates of relatively rigid plastic and the tubular shell from a plastic having some elasticity, such as polyethylene, with each partition plate being slightly oversize to attain a force fit.

Each partition plate 132 includes a gravity-operated valve means with a valve port therepast of appreciable flow area to communicate the annular supply chamber 131 to the adjacent one of the pair of receiving chambers the ball valve of FIGS. 19 to 22 incl. may be used for this purpose and thus each partition plate 132 is provided with a relatively large central circular hole to define a valve port 135. Each closed end 136 of the filler body 1369 is provided with a central cup-shaped socket 137 in which is loosely seated a ball valve 138. When either of the receiving chambers 134 is located above the supply chamber 131, the valve ball 138 rests in the bottom of the socket 137, which serves as a valve ball cage, appreciably below the inner mouth or annular edge 139 (serving as a valve seat) of the port 135, so that the latter is wide open for rapid spill of liquid from the topmost receiving chamber 134 down into the annular supply chamber 131. Free flow of liquid from such valve port 135 to the annular supply chamber 131 is assured by appreciably spacing the associated end 136 of the filler body therebelow without appreciable obstruction of the intercommunicating space. 'For this purpose each closed end 136 of the filler body 130 may be provided circumferentially with a plurality of widely spaced, longitudinally-extending short legs or nibs 149, such as six in number. Each of the elliptical valve plates 132 may have its inner face provided with a relatively shallow oval recess 141 into the marginal zone of which the tips of the nibs 140 are seated. Consequently, each of the closed ends 136 of the filler body 139 and the adjacent partition plate 132 are suitably spaced and arranged concentric with respect to each other, thereby locating the valve ball cage socket 137 coaxially inward of each of the valve ports 135.

Each of the partition plates 132 is provided with a plurality of small trickle passages 142 eccentrically located with respect to the center thereof and at angularly spaced points to communicate the supply chamber 131 with the adjacent receiving chamber 134 located on the opposite side of this partition plate. For example, a pair of such trickle passages may be located on diametrically opposite sides of the valve port 135, which may be in the form of pin holes 142 and 242. It will be seen from FIG. 23 that with respect to the lowermost receiving chamber 134, the canted bottom partition plate 132 thus disposes the small trickle passage 1-42 lower than the small passage 242 when the device 125 is in the upright position with its longitudinal axis arranged vertically.

A body of liquid 144 is housed in the container 125 of FIG. 23 for flow backand forth from one of the receiving chambers 134 to the other by way of the supply chamber 131. Such liquid may be colored to be readily apparent through the light-transmitting side wall 126, such as by being milky in appearance or a colored translucent liquid. The liquid 144 may be in a quantity sufficient substantially to fill one of the receiving chambers 134 up to the lowermost trickle passage 142, The remainder of the space in the container will be" filled with air.

In operation of the embodiment of FIGS. 23 and 24, let it be assumed that it is to serve as a toy chronometric timer. For this purpose the tubular shell 126 opposite the annular supply chamber 131 may bear scale markings 143, each indicating a minute duration of time, the time required for the surface of the body of liquid 144 in the supply chamber 131 to lower to the next scale marking while trickling through trickle passage 142.

Let it be assumed that the device of FIGS. 23 and 24 is rested in an upright position, such as that illustrated in FIG. 23; with the body of liquid 144, which has been in the uppermost receiving chamber 134, rapidly spilled down into the annular supply chamber 131 through the top valve port past the top ball valve 138. The toy timer device will then operate as follows. The liquid 144 will begin gradually to trickle, at 145, through the lowermost trickle passage 142 since the lower ball valve 138 seats upon the lowermost valve seat 139 and closes the lowermost valve port 135. Simultaneously, air bubbles 146 up from the lowermost receiving chamber 134 through the small passage 242 into the annular supply chamber space 131 through the body of liquid 144, countercurrent to the downward trickling of the liquid. The rising air bubbles 146 are intriguingly observable through the light-transmitting tubular shell wall 126. As the quantity of the liquid 144 in the annular supply chamber 131 is gradually depleted by this trickling at 145 the liquid surface 147 gradually lowers from one mark of the scale markings 143 to the next mark therebencath, to indicate a certain passage of time. Thus, the timer device appeals to the observer in a number of ways. The liquid in the supply chamber 131 seems to disappear. The bubbling action is intriguing. As the surface 147 of the liquid lowers in the supply chamber 131 from one of the scale markings to the next it indicates the duration of a definite interval of time.

When substantially all of the liquid 144 in the annular supply chamber 131 has trickled down through trickle passage 142 into the lowermost receiving chamber 134 the toy timer device 125 may then be inverted to place the liquid-containing receiving chamber 134 uppermost with the other air-filled receiving chamber lowermost. The lowermost valve ball 138 which will now be uppermost drops away from the port 135 which it was closing to permit rapid spill of the liquid down into the supply chamber 131, so that it may then trickle slowly therefrom down into the now empty lowermost receiving chamber 134, for repetition of the cycle.

A further embodiment of the invention is illustrated in FIGS. 25 and 26, which is an amusement container device for simulating repeated and alternate emptying of a pair of supply chambers having light-transmitting exterior walls for observation of receptive liquid contents thereof. In this form of the device of the present invention, container 151) embodies a pair of units of the types illustrated either in FIGS. 13 to 15 incl. or FIGS. 19 to 22 incl., each provided with its own supply chamber and associated receiving chamber separated by valved partition means equipped with trickle passages. The amusement container device 150 may be in the form of a cupshaped cylindrical shell 151 closed off by a transverse bottom 152 and provided with a tubular side wall 153 closed off at the top by a sealed cap plate 154. Within the bottom of the cup-shaped shell 151 is telescoped a tubular spacer sleeve 133 having a top edge 134 arranged on a plane extending obliquely to the longitudinal axis of the container shell 151, to provide a canted shoulder. A similar tubular spacer sleeve 133 is telescoped into the top end of the shell 151. Transverse elliptical partition plate 132 is seated against the shoulder 134 provided by the top tubular spacer sleeve 133 and a somewhat similar transverse elliptical partition plate 232 is seated against shoulder 134 provided by the top edge of the bottom tubular spacer sleeve 133. Thus the container 150 is subdivided into opposite

closed end sections

155, 255 and an intervening mid-section 156, with both of the end sections being hollow to provide a top receiving chamber 134 and a bottom receiving chamber 234.

The top transverse partition plate 132 is much like that of the embodiment of FIGS. 23 and 24 while the bottom partition plate 232 differs in detail. Thus, the top partition plate 132 is provided on its inner face with an oval shallow recess 141. The bottom partition plate is provided on its inner face with a shallow annular channel 241. Each of the

partition plates

132 and 232 is provided with a central valve port 135 defining by its inner edge a valve seat 139 with which cooperates a valve ball 138. The top partition plate 132 is also provided with the

small flow passages

142 and 242, which may be of pinhole size, radially outward of the shallow recess 141. The bottom position plate 232 is provided with small flow passages of the pinhole type 342 and 442 within the area of the shall annular channel 241.

The filler body of the embodiment of FIGS. 25 and 26,

position. The outer cup-shaped shell 157 has a closing transverse top wall 158 from which a tubular side wall 159 depends, with the bottom edge 160 of the latter seating in the outer marginal zone of the annular channel 241 and sealed to the bottom transverse partition plate 232 thereat. The transverse closing top wall 158 of the cup-shaped shell 159 is provided with central socket 137 to serve as a cage in which is loosely mounted top valve ball 138. The circumferential edge of the top closing transverse wall of shell 157 carries a plurality of circumferentially-spaced short legs or nibs 140 with the tips thereof seated into the shallow recess 141 of transverse partition plate 132, to space this top shell wall and this partition plate while maintaining them coaxial and providing communicating spaces for fiow from the top valve port to annular supply chamber 231 defined between the container shell side wall 153 and the side wall of inverted filler shell 157. The smaller inner upright filler shell 257 has a transverse bottom closing wall 161 and a longitudinally-extending cylindrical side wall 162 with the top edge 163 of the latter seated against and sealed to the inner face of the top closing wall 158 of the inverted filler shell 157. Thus, the tubular side walls 162 and 159 of the

respective filler shells

257 and 157 define therebetween an inner annular supply chamber 331. The bottom transverse closing wall 161 of filler shell 257 is also provided with a central socket 137 which serves as a housing cage for the other valve ball 138 that cooperatively seats on the inner edge 139 of the valve port 135 formed in the center of the bottom transverse partition plate 232. The transverse closing bottom wall 161 of the inner upright filler shell 257 carries on its circumferential edge a plurality of depending short legs or nibs 140 which seat on the inner annular zone of the annular channel 241, thereby accomplishing the spacing and providing the communicating flow passages described above in connection with the top end of the inverted filler shell 157. As a result, the

small flow passages

142 and 242 communicate the outer annular supply chamber 231 to the topmost receiving chamber 134. Likewise the small flow passages 342 and 442 communicate the inner annular supply chamber 331 with the bottom receiving chamber 234.

Let it be assumed that when the device is constructed a body of colored translucent liquid 164 (which may, for example, be blue in color) is located in the outer annular supply chamber 231, with the receiving chamber 134 associated therewith being air-filled. If the inner annular chamber 331 is likewise provided with a body of colored translucent liquid 165 (which may, for example, be yellow in color) it will in the upright position of the container shown in FIG. 25 begin trickling down at 166 through trickle passage 342 to collect in the receiving chamber 234 as a pool 265. Simultaneously, air in the bottom receiving chamber 234 will flow countercurrent up through the small flow passage 442 to produce rising bubbles 167 in the yellow liquid 165. Since the yellow liquid may be observed through the light-transmitting wall 159 of the outer inverted filler cup 157, the body of blue translucent liquid 164 in the annular supply chamber 231 and the light-transmitting side wall 153 of the container shell 151 the color of the midsection 156 of the container 150 will appear to be a shade of green. If the size of the bubble transfer passage 442 is so related to the radial spacing of the filler shell walls 162 and 159 so that each bubble 167 will bridge thereacross to provide a circular Window each of these bubbles will appear to be blue. Thus, the external appearance is blue bubbles rising in a body of green liquid. If the tubular side wall 162 of the inner upright filler shell 257 of the FIG. 25 device is provided.

with a certain difierent color, such as red, which may be attained by making this inner filler cup from opaque red plastic, each of the bubbles 167 may then appear to be purple (a mixture of the red of the tubular wall 162 and of the blue of the liquid 164).

When the amusement container device 150 of FIG. 25 is inverted to rest upon its top end 154, as is proposed in FIG. 26, the lower valve 138, which is now uppermost, will drop away from the valve port 135 in the partition plate 232 to permit the yellow liquid 165 to flow rapidly therethrough from the now uppermost receiving chamber 234 down into the inner supply chamber 331. The valve port 135 in the partition plate 132 will be closed by its associated valve ball 138 and the blue liquid 164 will begin to trickle at 266 through small flow passage 142 into the now lowermost receiving chamber 134 with simultaneous countercurrent transfer of air from the latter up through small flow passage 242 to form bubbles 267 rising in the body of blue liquid in the outer annular supply chamber 231. The blue liquid 164 which trickles through at 266 into the receiving chamber 134 collects in the latter as a pool 264. The mid-section 156 of the container device 150 will still appear to be of a shade of green while these bubbles 267 will appear to be yellow.

Incidentally, in the first instance of operation of the FIGS. 25 and 26 device as the surfaceof the yellow liquid 165 lowers in the annular supply chamber 331, the green shade of the container mid-section 156 above the surface of this liquid will appear to change to blue which will progressively advance downward (or progressively to purple if the side wall 162 of the inner upright filler cup 257 is of red color). In the inverted position, as the blue liquid 164 trickles from the outer annular supply chamber 231 the top end of the mid-section 156 of the container 150 above the level of the blue liquid will appear to be yellow while that below the blue liquid level will appear to be green, and the yellow shade will progressively advance downward (but should the inner filler shell 257 be red the color of this top section will turn to orange progressively) v In the embodiment of FIGS. 25 and 26, the tubular spacer sleeves 133 may be light-transmitting or transparent so that as the yellow liquid 165 is collected in the receiving chamber 234, the lower section 255 of the container will appear progressively to turn yellow. In the inverted position of the container 150, with the other tubular spacer sleeve 133 in receiving chamber 134 also being light-transmitting or transparent, the Walls of this receiving chamber will appear progressively to turn blue when the blue liquid 164 collects therein. The tubular spacer sleeves 133 may be opaqued so that the yellow liquid 165 as it trickles into the receiving chamber 234 and the blue liquid 164 as it trickles into the receiving chamber 134 will seem to disappear. It will be understood that various color contrasts and changes may be attained in such a device.

It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language,

might be said to fall therebetween.
