Abstract: A user controllable noncollapsible variable stream physiological dispenser for a container is disclosed which comprises a nipple having a top nipple portion which extends to an intermediate concave section which extends to a lower dome-shaped body and to a flange, the flange used for being held to a bottle by a collar, the nipple having openings formed in the top nipple portion, an open bottom provided at the flange with the nipple having a hollow body through which liquid may pass from the open bottom through the body and out the openings.

Abstract: A nursing bottle (1) formed of a large volume container, incorporating a vent tube (3) that extends inwardly of the container, having a vent port (4) arranged approximately at the volumetric midpoint (12) of the container, so as to allow for venting of pressure, whether of excessive or vacuum, to the atmosphere, at all times. The volumetric capacity of the nursing bottle container may be formed of a spherical shape (1), hemispherical shape (40), cylindrical shape (18), or to other configurations that provide for the internal volumetric capacity so that any formula placed therein will be prevented from blocking the vent port (4), the vent tube (3), regardless of the angular disposition undertaken by the nursing bottle during usage.

Abstract: A nursing bottle formed of a large volume container, incorporating a vent tube that extends to vent pressure at all times. The nursing bottle may have a cylindrical shape or other configuration that prevents formula placed therein from blocking the vent tube regardless of its angular disposition. The vent tube extends distally from the vent insert, operatively associated with a collar, that holds the vent structures and the nipple to the wide rimmed opening. In addition, the vent tube has a conical shape of decreasing diameter distally toward the center of the bottom to dissipate the pressure that may cause leakage from the bottle. Further, the vent insert has a major and minor seal that prevents leaks out of the collar and onto an infant.

Abstract: A nursing bottle formed of a container, incorporates a reservoir and venting tube that eliminates vacuum. The nursing bottle has a cylindrical shape or other configuration that prevents formula therein from blocking the venting tube when held at any angle. The venting tube extends distally from the insert and alternatively may be in separate pieces. The insert has a flange on its perimeter, extending inferiorly and securing the insert to the superior and lateral aspects of the neck of the container. The vent opens at the volumetric center of the reservoir above the conically shaped venting tube depending from the reservoir, where the venting tube has a conical shape of decreasing diameter.

Abstract: A nursing bottle formed of a small volume container, incorporating a venting tube that extends to dissipate pressure at all times. The nursing bottle may have a cylindrical shape or other configuration that prevents formula placed therein from blocking the venting tube when held at any angle. The venting tube extends distally from the insert portion, operatively associated with a collar that holds the vent structures and the nipple to the neck of the container. The vent opens at the volumetric center of the reservoir above the venting tube. Alternatively, the venting tube has a conical shape of decreasing diameter distally toward the center of the bottom to dissipate the pressure that may cause leakage from the bottle.

Abstract: A vent prevents a vacuum within an inverted container of liquid and eliminates components found in other container vents. The vent utilizes a conical or other shaped venting tube extending from the closure or a reservoir with reservoir extension and an air conduit extending inferiorly from a closure. The closure is either a leak resistant or leak proof seal. The superior aspect of the reservoir contains an inferiorly projecting air conduit, opening at the volumetric center of the reservoir. The reservoir extension projects distally into the container to reach the inferior aspect of the container. The vent provides an airway between the outside and the interior of the container so air freely passes to the distal aspect of the container without contaminating the liquid. Any liquid within the reservoir extension then collects in the reservoir during inversion of the container and then returns to the container when upright.

Abstract: A fully and continuously vented drinking cup or container for infants and children, which consists of a vessel or container for containing a liquid or formula, having a resilient spout which rests upon its uppermost edge. The interior aspects of the feeding spout, and the feeding diaphragm, are all molded so as to arrange the diaphragm slit, or opening through which the liquid flows, in a position that will be vertically aligned between the lips of the infant feeding, to thereby allow the infant to open the spout and allow the liquid to flow, just as if the child is drinking from a cup. The diaphragm may be shaped concavely, with respect to the structure of the feeding spout.

Abstract: The present invention is a pacifier having a non-collapsible aperture within the nipple lengthwise and a vertical aperture crosswise. The pacifier has a superiorly arched nipple upon a guard and opposite the nipple, a tab for grasping. The horizontal aperture extends from the tip of the nipple and through the guard. The horizontal aperture allows the passage of air into and out of the pacifier as an infant breathes and has a rib extending lengthwise that prevents collapse of the aperture. However, as infants salivate when suckling on a pacifier, the vertical aperture permits drainage of saliva, that enters the horizontal aperture, back into the mouth of an infant. The guard has a generally oval shape. Alternatively, the nipple deviates superiorly and close to the proximal end, has recesses for teeth or gums, and a hole in the tab for a strap or keeper.
