Abstract
A self-contained attachment unit which is to be connected between the mouth of a baby nurser and a nipple, including a liquid flow path having a variable internal diameter, and an adjuster for varying the internal diameter, a track path following the liquid flow path to guide the adjuster along the liquid flow path for controlling the size of the internal diameter from its maximum to closure to vary liquid flow from the baby nurser to the nipple from a maximum to complete shut off of flow.
Claims21
A liquid flow control for a baby nurser to control the flow of liquid contents contained in a baby nurser to a nipple dispenser adapted to be sucked on by an individual such as a baby, including
- a self-contained unit having an entry end and an exit end, spaced axially from each other;
- a pair of spaced locating members removably coupled with an inner wall of said self-contained member and each having a central opening;
- a flexible tube extending from one end of said member to the other end thereof and passing through said central openings, said flexible tube having a longitudinal axis;
- a liquid flow entrance mechanism associated with said entry end adapted to be received within the mouth of a baby nurser and having an opening for receiving one end of said flexible tube for applying liquid from said baby nurser to said nipple and providing an exit for the flow of gas bubbles in a direction opposite to the flow of the liquid;
- a flexible tube constrictor associated with said flexible tube for varying the internal diameter thereof for controlling the flow of liquid through said flexible tube;
- and
- a control member associated with said flexible tube constrictor movable along an axis substantially coaxially with said longitudinal axis.
A liquid flow control attachment for a baby nurser to control flow of liquid contents contained in the baby nurser to a nipple dispenser adapted to be sucked on by an individual, comprising:
- a self contained unit having one end including means for connection to the baby nurser and another end including means for connection to a nipple;
- first means associated with said one end for receiving the liquid from the baby nurser and transferring it to the other end;
- second means associated with said other end for transferring the liquid from the baby nurser to the nipple;
- flow rate control means comprising liquid path means having a variable flow path coupling said first and second means for controlling the rate of flow of the liquid, and adjustment means operatively associated with said liquid path means for adjustment thereof for controlling the quantity of liquid passing from the baby nurser to the nipple, said adjustment means being movable along a path following said flow path;
- and
- closure means for preventing access to said flow rate control means.

- a self contained attachment unit having one end including first means adapted to be connected to the baby nurser and another end including second means adapted to be connected to a nipple;
- flow rate control means comprising liquid path means coupling said first and second means;
- control means associated with said liquid path means for controlling the quantity of liquid passing from the baby nurser to the nipple;
- adjustment means associated with said control means movable along an axis coaxial with the axis of the liquid path means;
- and
- closure means for closing off access to said adjustment means.
