The portable milk powder container includes a milk powder container body, a dispensing mechanism, a milk powder taking bin, and a bottom cover. The milk powder container body is rotatably connected to the dispensing mechanism around a central axis of the portable milk powder container. The dispensing mechanism is detachably connected to the milk powder taking bin. The bottom cover is detachably arranged on a bottom portion of the milk powder container body. By rotating the milk powder taking bin, the dispensing mechanism is made to rotate relative to the milk powder container body, so milk powder in the milk powder container body is guided into the milk powder taking bin according to the required amount, which realizes the measurement of the milk powder and the dispensing of the milk powder, and thus making the portable milk powder convenient and fast to use.

A drink container with torque-limiting lid is provided. The drink container includes a lid that can be threadably coupled to a container body having a volume to hold fluids. The lid can include an inner lid assembly concentric with an outer lid assembly. The inner lid assembly can include a multiple ratchet teeth along an outer perimeter and the outer lid assembly can include one or more ratchet pawls along an inner perimeter and configured to engage the ratchet teeth. Rotational force on the outer lid assembly can be transferred to the inner lid assembly from the ratchet pawls to the ratchet teeth to threadably couple the inner lid assembly to the container body. Once a torque limit is reached, the ratchet pawls can slip along the ratchet teeth preventing further tightening of the inner lid assembly to the container body.

A container for collecting, transporting, storing, delivering and dispensing fluid. The container has a hollow tube with an outer circumference diameter and is configured to receive a plunger. A collection adaptor and a dispensing adaptor provide interchangeable coupling of a variable volume container such as a syringe with a collection device such as a breast pump and a dispensing device such as a nipple. The container also has a circumferential seal assembly secured at one end of the hollow tube. The seal assembly outer diameter is substantially similar to the hollow tube outer diameter.

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.

The disclosure includes embodiments of an apparatus, a device, and methods to transform an infant feeding bottle into an infant gavage feeding apparatus. According to an embodiment, an infant gavage feeding apparatus can include an infant feeding bottle, a gavage milk delivery component, a retaining ring, and a cord component. In another embodiment, an infant milk dual-delivery device to transform an infant feeding bottle to an alternate nipple feeding and gavage feeding apparatus includes a gavage milk delivery component, a retaining ring, and a nipple receiving component. The gavage milk delivery component and the nipple receiving component can be positioned in a branched or a stacked configuration. The device can include a flow closure component and a controller to transition the milk flow for a gavage feeding and nipple feeding. The device can include a funnel to allow milk in the nipple to flow back into the infant feeding bottle.

A bottle assembly includes a container having an open end, a closed end, a base portion, and a neck together defining a liquid chamber within the container. The neck has a rim defining the open end of the container. The bottle assembly also includes a collar assembly generally defining a closure for the container. The collar assembly is configured for releasable engagement with the neck of the container over the open end thereof. The collar assembly includes a collar and a nipple. The bottle assembly further includes a cap including a closed end, an open end, and a side wall extending between the closed end and the open end together defining an interior. The cap is configured for releasable engagement with the collar assembly such that the nipple is received within the interior of the cap. In some embodiments, the bottle assembly includes a vent assembly positionable at least in part on the rim of the container to permit venting of the container during use.

The present invention is a universal replacement lid with nipple assembly that removably affixes, via threading, to inter alia thermally insulated bottles. The instant invention features a replacement lid with a cylindrical hole through the center. The [bottle's] replacement lid [and its corollary attachments, components and features] turn an ordinary bottle into a universal baby-bottle. Atop said hole (annular aperture), rests a ridged rim/lip, under which is positioned a plastic nipple (with optional lugs to further secure said nipple in place in the deployed position). A sealing disc and a half-eggshell-cap together prevent spillage when not in use. The nipple clips in under the lid ridged lip, and may be stored upside down when the bottle is not in use. This feature, combined with the novel feature of a sealing disc, allows for secure, leak-proof nipple storage. When in use/deployed-position, the nipple simply turns right-side-up and clips in to the [bottle] replacement lid [positioning itself just underneath the outer-circumference ridge-lip], allowing for normal dispensation of liquid to the baby. Alternate embodiments also function as a replacement-lid-nipple (with valved-spout) for toddlers' sippy-cup type devices, as described infra and supra. Also of note is that said invention is compatible with both aluminum bottles and also double-walled thermally insulated bottles.
