A vessel intended to contain a fluid including a container delimiting an inner volume made of a flexible material and topped with a tubular sleeve whose proximal end delimits a housing. The sleeve includes an upper shoulder projecting radially outwards of the sleeve. The vessel also comprises a removable closure device made of a flexible material including a lower shoulder adapted to interact with the upper shoulder of the sleeve so that tightness is ensured when the lower shoulder and the upper shoulder are compressed against one another. The vessel also includes a coupling system enabling holding and mutual compression of the lower shoulder of the removable closure device and of the upper shoulder of the sleeve.

A feeding bottle has a first layer and optionally a second layer. The feeding bottle offers an improved user experience by mitigating against spills, leaks, improving feeding comfort, or offering information to the user about the feeding environment. The feeding bottle has a reusable liner that is compatible with breast pumps. The liner stores fluid such as breast milk in the freezer. The liner is adaptable to feeding bottle holders, collars, and/or nipples and thus facilitates feeding infants. The liner is adaptable to breast pumps, a liner cap, and one or more of a bottle holder, collar and nipple, such that the liner offers a pump, store, feed solution that is reusable and simplifies the number of parts required for any/all of pumping, storing and feeding activities.

A combined infant feeding and pacifier retention device is an apparatus used to retain and distribute breastmilk or other fluids. The apparatus is also configured to store a pacifier for selective use. The apparatus comprises a liquid retention chamber, a pacifier retaining mechanism, and a feeding spout. The liquid retention chamber is a contained volume that enables transportation of inserted liquids, particularly milk or breastmilk. The pacifier retaining mechanism is a unit that enables storage of any of a variety of pacifiers. The feeding spout is a unidirectional valve that enables fluid transfer from the liquid retention chamber. The feeding spout is preferably made of any of a variety of soft, bisphenol A-free (BPA-free) materials that effectively operates when utilized as a mouthpiece for an infant. The general configuration of the aforementioned components allows the apparatus to efficiently and effectively store and distribute fluids to users.

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 system includes a first housing having a first sealable opening and a distal end, between which a second sealable opening is located, and a first storage chamber being defined between the first and second sealable openings of the first housing. The bottle also includes a second housing having a second storage chamber defined between a third sealable opening and a base, with the first housing and the second housing adapted to be rotatably coupled relative to each other in an end-to-end configuration between at least a first state, in which the first and second storage chambers are separated from each other, and a second state, in which the first and second storage chambers are coterminous. The bottle also includes a cutter such that, in use, the cutter pierces seals of the second and third sealable openings as the first and the second housings are rotatably actuated.

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.

A disposable receptacle useful with an infant feeding system, including a pliable pouch. The pliable pouch may have a single compartment, or a pair of compartments wherein a first compartment is filled with powdered formula, and a second compartment is filled with distilled water. When compartmentalized, the compartments are separated by a burst seal designed to fail upon subjection to pressure of between about 1-3 lbs. The receptacles include a cylindrical fitment with a one-way valve removably positioned therewithin. A top seal of the pliable pouch is secured about the body of the fitment. The receptacles may be used with an infant feeding system having a support disc with an aperture to receive and secure the fitment, and a nipple having an internal chamber sized and configured to tightly and removably receive a portion of the fitment. The infant feeding system may optionally include a bottle and a securing ring.
