Dripless liquid feeding/training containers
First Claim
1. A dripless liquid feeding and training container, useful for babies, toddlers, and others, comprising:
- a) a liquid housing means;
b) said liquid housing means, further comprising a housing interior, which is suitable for temporary storage of liquids at an interior pressure;
c) said liquid housing means containing a liquid;
d) a liquid housing sealing lid means;
e) said liquid housing sealing lid means, being removably-attached to said liquid housing means, such that it fully encloses said liquid, contained within said housing interior of said liquid housing means;
f) said liquid housing sealing lid means further comprising a drinking spout means, a liquid outlet control valve means, which is incorporated within, and contiguous to, and is in a liquid inter-connecting relationship with said drinking spout means, and an air inlet control valve means;
g) said drinking spout means further comprising a liquid outlet, which allows a user to sip or suck liquid driplessly out of said liquid housing means; and
h) said air inlet control valve means additionally including further means for automatically allowing air to enter said interior of said liquid housing means during the exiting of said liquid, thereby replacing the space formerly occupied by said removed liquid, and re-equalizing the interior pressure of said liquid housing means with pressure exterior to the liquid housing means.

Abstract
Dripless liquid training/feeding containers, being either a cup and/or a bottle, are described, particularly useful and suitable for babies, toddlers, as well as others requiring them. In operation, a liquid is first placed into, for temporary storage within the container'"'"'s liquid housing. The container housing is then enclosed by a removably-mounted container sealing lid. During use by a baby or toddler, the liquid stored within the container, is slowly sucked or sipped out of the container'"'"'s liquid housing, by means of a liquid outlet control valve, incorporated preferably within the container'"'"'s sealing lid. As the liquid is removed by the user sucking or sipping through the liquid outlet control valve, located within a drinking spout, an air inlet control valve, which may preferably be also incorporated within the container'"'"'s sealing lid, or in the liquid housing acting in concert with the liquid leaving the container, allows air to flow into the cup, during the sipping, resulting in equalization of the interior/exterior pressures, which, at the same time, results in filling of the space previously occupied by the liquid, that has been sipped out of the cup housing. During the sipping/sucking process, as well as non-use, the container, in all likely orientations and movements, will not drip its liquid contents, while outside the user'"'"'s mouth.
