A baby bottle assembly for bottom venting includes a bottle having a top closure member adapted for releasable engagement with a top portion of the bottle, and a bottom closure member adapted for releasable engagement with a base portion of the bottle. The bottom closure member has a base panel with a raised portion having an air passage therethrough and a top sealing surface. A diaphragm is positionable between the bottom closure member and the base portion. The diaphragm has a disc, at least one moveable sealing element for sealingly engaging the top sealing surface, and an air passage extending under the at least one moveable sealing element into the liquid chamber. The diaphragm is moveable between a sealed position and an unsealed position. The moveable sealing element when in the sealed position prevents liquid contained within a liquid chamber of the bottle from entering the air passage. When in the unsealed position, the diaphragm allows bottom venting of the bottle.

There is disclosed a drinking receptacle comprising: a container for containing a fluid for drinking; and an outlet member having an outlet through which the fluid is delivered under a pressure supplied by a user of the receptacle and a collar portion that attaches to an opening of the container such that an undersurface of the collar portion abuts with an upper surface of the opening of the container to form a substantially sealed engagement between the outlet member and the container; wherein either the undersurface of the collar portion or the upper surface of the opening of the container has at least one vent formed therein, the at least one vent being configured such that when said pressure is applied to the outlet member the at least one vent member permits the controlled ingress of air into the container to facilitate flow of fluid from the outlet, and when said pressure is removed the at least one vent member substantially prevents the ingress of air into the container to facilitate a controlled vacuum pressure within the container.

A valve assembly for a leak resistant drinking cup includes a tubular plug having an outer wall, an inner wall, and a web extending between and connecting the outer and inner walls. The web has at least one slit disposed intermediate the inner and outer walls. The valve assembly is configurable between a sealed position wherein liquid is inhibited from passing through the slit and an unsealed position wherein liquid can pass through the slit.

A kit of parts for a feeder has a body and a bung that can slide within the body. A periphery of the bung can form a sliding seal between that periphery and the internal side walls of the body. A base cap has an aperture and is mountable at a lower end of the body to substantially occlude that end and allow airflow through the aperture into the body as the bung moves away. The kit has a teat mouthpiece for liquid foods, a sipper mouthpiece for pureed food, and a spout mouthpiece for mashed food and a pump attachment. The pump attachment has a pump and a spoon. The pump has a pump bung which moves reciprocatingly within the body and forms a sliding seal with the internal side walls. A valve allows food to flow from the feeder but prevents the flow of food into the feeder.

A wind detection device with a flexible enclosure, and opening, and a dispensing tube, filled with powder or liquid and designed to be attached to hunting equipment, headgear, or clothing, wherein pressing on the outside of the device causes a puff of powder or vapor to be dispensed into the air, allowing the user to determine wind direction.

Disclosed is an infant feeding bottle having a means of mixing powdered baby formula, or other substance, at individually separate times, within any of multiple internal chambers which may be filled with water or other liquid. A user operates the device by removing one of a plurality of attached powder dispensers and pouring its contents, through an open loading portal, directly into one of the chambers within a cylinder main body. A canister top is fabricated with an off-center nipple and, when secured to the cylinder main body, prevents spillage of contents of the chambers. The user selects and detaches one of the plurality of powder dispensers, combines its contents with water or other liquid in a selected chamber, mixes thoroughly, and dispenses to an infant, as necessary. Thus, there are provided multiple uses of the same bottle at different times.

A bottle assembly is provided including a bottle having an end portion with a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided including a base member and a sealing member. The sealing member is movable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.
