Abstract: 941,214. Toys. P. H. KNOTT. Aug. 17, 1962 [Aug. 24, 1961; July 27, 1962], No. 31628/62. Heading A6S. [Also in Division G3] A container for simulating repeated emptying of a compartment with light transmitting walls comprises at least one receiving chamber and a supply chamber with light transmitting walls separated by at least one partition, a lower section spaced from the light transmitting walls to provide a circumscribing supply chamber, the or each transverse partition having a gravity operated valve for putting the supply chamber into communication with the or a receiving chamber when the container is inverted the or each partition having small apertures to allow trickle flow of the liquid and bubbling of air therethrough. A bottle 20 which may be-in the form of an infant's feeding bottle has an opaque liquid receiving chamber 40 above an annular liquid containing supply chamber 25 formed by an inner section 24 concentric with the transparent bottle. A transverse partition rests on the upper end 28 of the inner section 24 and has a diameter smaller than that of the container to allow rapid return flow of liquid 26 in the receiving chamber 40 to the supply chamber 25 and when the bottle is inverted rests on shoulders of a ring 34 fitting in the bottle and retaining the chamber 40. The partition has one or more notches which provide trickle flow from the supply chamber 25 to the opaque chamber 40 and bubbling of air visible in the chamber 25 or the partitions may lift slightly to allow the air to bubble into the chamber. The partition may form part of a plug 41, Fig. 11, with a socket 53 opening into the neck chamber of the bottle by a port 61 which serves as a valve seat for a ball valve 55 when the bottle is inverted. The ball valve has intersecting diagonal passages 57, 59 which provide trickle passages for the liquid. The bottle may have a labelled neck 42c, Fig. 15, mounted on a ring 34c with a flange inserted into the end of the bottle above a partition 30c with a plurality of pin holes or notches which allow trickle flow of liquid when the bottle is inverted and allows bubbles 67 to rise in the liquid. The bottle may be mounted on a panel 52, Fig. 17, to rotate to an upper position by means of a motor 56 driving a segmental gear 74 which intermittently engages a further gear 78 on a shaft connected to a spring bottle clamp 80 (not shown), when the gears disengage the bottle falls under gravity to a position where the bottle appears to empty into the mouth of a doll's head 82. The inner section may comprise tubing 103, Fig. 19, closed by a spider 97 fitted into each end, the lower spider seating on a shoulder of the outer container and the upper spider being spaced by legs 113 from a partition 107 seating on a lip on the upper edge of the bottle. The partition has a series of peripheral notches 109 which provide trickle passages, further passages may be provided by pin holes. The partition has a central port 111 providing a valve seat for a ball valve 119. The device may have the form of a timer having time scale markings 143 on the outer container. The container has a receiving chamber 134 at each end of a supply chamber 131 closed by an oblique partition 132 having a port for a ball valve 138 and trickle passages 142, 242. The partitions are spaced from the inner body 130 by legs 140, and the end walls of the inner body have recesses 137 for the ball valves 138. The container may be provided with two inner concentric tubular shells 157, 257, Fig. 25, with translucent or transparent walls to provide two supply chambers containing liquid of different colours so that a number of colour effects are obtained for both the liquid and the bubbles. At one end the partition seals the outer supply chamber and has trickle passages communicating with the inner supply chamber. At the other end the partition has trickle passages communicating with the outer supply chamber. The wall of the inner shell may also be coloured to increase the colour combinations. The receiving chambers may be transparent or opaque.
