Abstract: An infant feeding bottle that is nipple-equipped at one end that is further equipped with a pressure equalizing apertured diaphragm member at the opposite end. The diaphragm member allows room air to pass therethrough into the air space in the bottle when the bottle is inclined and liquid is withdrawn through the nipple, thereby equalizing the interior air pressure. The diaphragm member is gas and liquid tight when the inside and outside pressures are equal and the bottle is in an upright configuration with the feeding liquid resting on the diaphragm member. The diaphragm member has a central portion which is dome configured and provided with apertures that are in a sealed shut configuration when the diaphragm member is relaxed yet that are opened when the diaphragm member is expanded responsive to differential air pressure.

Abstract: An infant chair structure having upper, lower and interconnecting main frame members, a leg support frame member, and an optional toy bar connector for joining the leg support frame member and the toy bar to desired locations along the upper frame member are provided. The chair structure has decentralized interconnections which avoid the problems of centralized connectors.

Abstract: A chair structure provided which can be used by young children either as a bouncer or as a rocker. The structure is defined by a frame member having a pair of transversely spaced, generally U-configured side portions and at least one seat member raised above a support surface. The frame member is oscillatable or rockable depending upon which one of the opposite end portions thereof is engaged with the support surface. Preferably, the structure incorporates a unitary frame member and single seat cover member that is adapted to slip over either opposite end region of the frame member, whichever one of the end regions is positioned uppermost relative to a floor surface. In one orientation, straightened portions of the frame member are floor engaged causing the upper frame portions to be vertically oscillatable. In a reverse orientation, curved portions of the frame member are floor engaged causing the upper frame portions to be horizontally and reversibly tiltable.

Abstract: A foldable, portable toilet seat is provided having foldable front and rear sections that are pivotably connected by hinges. The lower surface of each front section includes a downwardly extending flange for engaging a conventional toilet seat to prevent slipping or movement. The flange of each front section interfits within a hollow raised portion of the corresponding rear section when the sections are folded for convenient transport and storage.

Abstract: A booster seat is provided having an inflatable lower portion which can be generally donut-shaped and an inflatable upper portion which can be generally U-shaped. The lower portion and the upper portion are hinged together whereby the inflated upper portion is folded over and is secured against the upper surface of the inflated lower portion to provide a seat pocket in which a child can sit.
