The device of the present invention includes a compact baby bottle attachment. The device of the present invention is a pod that is functional as a cap to a baby bottle, a storage container for powdered formula, and a dispenser for powdered formula. The device is removably attachable to conventional baby bottles and eases the baby feeding process by storing powdered formula separately from the water reservoir, sealing the powdered formula compartment with a ring plug, and including a nip housing depression to ensure the nip is erect and ready to feed upon removal of the pod.

A baby bottle system includes a collar configured to connect to a disposable water bottle, a nipple secured to the collar, and a dosing cap configured to connect to the collar and enclose the nipple. The collar includes a lower portion configured to engage the disposable water bottle and an upper portion attached to the lower portion, a base of the nipple being sandwiched between the upper portion and an upper end of the lower portion to secure the nipple to the collar.

A single-use, multi-compartment infant formula pouch is disclosed. The pouch includes a substantially flat, flexible body formed from a laminate material including an aluminum foil layer. It contains two internal compartments: one pre-filled with powdered infant formula and the other with purified or distilled water. The compartments are separated by a frangible heat seal that ruptures upon applied pressure, enabling mixing just prior to use. The pouch also includes an integrated silicone nipple sealed beneath a removable cap, with the nipple secured into a spout by an internal locking ring to prevent user disassembly. During manufacturing, the pouch is filled under sterile conditions, including nitrogen gas injection and humidity control, to ensure long shelf life and inhibit microbial growth. The result is a tamper-evident, ready-to-feed, disposable system requiring no additional components or assembly.

An infant feeding bottle assembly includes a container and a top assembly including a collar coupled to the container at a top portion of the container, a nipple, and a nipple protector. The collar further includes a holding portion. The nipple protector is coupled to the collar and is capable of transitioning between an open state and a closed state. In the closed state, the nipple protector covers and protects the nipple. In the open state, the nipple protector retracts into or rests on the holding portion and exposes the nipple.

A bottle assembly includes a container, a collar assembly, and a vent insert. The collar assembly includes a collar and a nipple. The vent insert is configured for selective placement on an open top of the container. The vent insert, when placed on the open top of the container, defines a gap for allowing liquid in the liquid chamber of the container to flow towards the nipple and a vent passage having at least one vent opening in flow communication with the liquid chamber for allowing air to flow into the liquid chamber. The vent insert further defines an annular gap forming a portion of the vent passage. The bottle assembly is selectively operable in two different configurations, a first configuration in which the vent insert is placed on the open top of the container and a second configuration in which the vent insert is omitted.

A feeding bottle includes a bottle enclosure defining a hollow bottle chamber, wherein the enclosure defines a feeding outlet at a first end and an attachment structure 26 at a second end. A bottom housing defines an instrument compartment extending between a closed exterior portion of the bottom housing and a separation surface within the bottom housing, wherein the bottom housing is configured for detachable connection to the attachment structure 26 of the bottle enclosure. A relief valve is positioned within the separation surface of the bottom housing. A pressure sensor is positioned adjacent the separation surface of the bottom housing and connected by a passageway to the instrument compartment in the bottom housing, wherein the pressure sensor is configured to detect changes of pressure in the bottle enclosure.

In an embodiment, there is provided a bottle which contains liquid milk and dispenses liquid medication, comprising a bottle, wherein the bottle is defined by a cylindrical body with a top end and a bottom end, and wherein the cylindrical body contains a central passage; a cap attached to a nipple, wherein the cap has a top end and a bottom end, wherein the nipple has a tapered end and a non-tapered end, and wherein the non-tapered end of the nipple is attached to the top end of the cap; a sealed vacuum, wherein the sealed vacuum is of conical shape and wherein the sealed vacuum contains a central passage; and a syringe, wherein the syringe is defined by a top tapered end and a bottom end, wherein the syringe lies in the central passage of the bottle, wherein the top tapered end is contained within the mixing chamber of the nipple through the central passage of the sealed vacuum and wherein the bottom end features a plunger.

In an air-return valve and an air-return container, the valve includes a valve body and an air path formed through the valve body. The valve body has a lip portion above a valve body portion, which is a boss enclosed by a diaphragm. The air path penetrates the valve body portion, and the valve lip portion has an air gap connected to the air path. The air gap is closed when the interior of the container is not under negative pressure; and the air gap is open when the interior of the container is under negative pressure. The container body has a mounting hole with which the air-return valve makes an interference fit. The air-return valve can have a one-way communication effect, and makes air return to the air-return container to compensate for a negative pressure in the air-return container.
