A dosing apparatus suitable for dispensing a dose of liquid from a resilient squeezable container including a cap, suitable for attachment to the container, the cap comprising an expulsion channel for the expulsion of liquid; a dosage chamber attached to the cap, the dosage chamber comprising side walls; at least one inlet opening in the side walls proximal to the cap; a pressure chamber located underneath the dosage chamber; a valve provided at the end of the pressure chamber distal to the dosage chamber, the valve being movable from an open position, allowing liquid to flow through one or more discharge openings, and a closed position where the valve closes each discharge opening, the valve incorporating at least one aperture; and a plunger provided in the dosage chamber, and movable relative to the dosage chamber so as to advance upon squeezing of the container, up to a blocking position.

The invention relates to a container (10) for liquids or free-flowing materials, with an inner container (20) with a wall (21) made of metal, a filling opening (22) and an outlet opening (23), wherein the wall (21) of the inner container (20) has a wall thickness of less than 1 mm and the inner container (20) is enclosed by a lattice structure (30) comprising rods (32, 34, 35, 36).

A multi-compartment bottle includes an upper compartment having a bottom, an open mouth opposite the bottom, and a sidewall cooperating with the bottom to bound an internal reservoir. A lid is fit to the open mouth to enclose the internal reservoir. The bottle further includes a lower compartment separate from the upper compartment, having a base, an open top opposite the base, and a wall cooperating with the base to bound an internal chamber. The bottom of the upper compartment is applicable to the open top of the lower compartment to enclose the internal chamber. The lower compartment includes engagement structures which extend into the internal chamber from the wall to define a hold in the lower compartment.

A liquid refill container for refilling a liquid discharge apparatus with liquid includes a liquid storage portion, a pouring portion, and a cap portion. The liquid storage portion is made of a metal and contains liquid. The pouring portion is removeably connected to the liquid storage portion and has an outlet for pouring the liquid. The cap portion is removeably attached to the pouring portion and covers the outlet.

A non-spill drinking cup system includes a container; a lid assembly that is removably attachable to the container, comprising an aperture; and a drinking tube, wherein the drinking tube extends through the aperture, the drinking tube including an open end, a closed end, and a side wall; and a drinking valve, wherein the drinking valve includes at least one elongate slit disposed within the side wall.

The present invention discloses an eco-friendly recyclable dropper, comprising a pressing portion and a pipette, wherein a bottom of the pressing portion is wrapped around a top of the pipette, wherein a bottom inner wall of the pressing portion includes a concave groove, wherein a top outer wall of the pipette includes a corresponding convex circle, wherein the concave groove matches with the convex circle and become airtight based on the characteristics of both material, wherein the pressing portion is made of PE material, wherein the pipette is made of PP material. Since the pressing head is made of PE material or a mixture material of PE and PP, and the pipette is made of PP material, a combination of the pressing head and the pipette is better in airtightness comparing to prior arts using glass pipettes; furthermore, the design of the pressing head and the concave groove and the convex circle of the pipette provides better airtightness; the dropper and the bottle of this invention both used PP and PE material, which can be fully recycled and reused after using the liquid within, avoids environmental pollution and saves resources. The market of this invention is very wide and this invention has a breakthrough meaning in the dropper field.

In some embodiments, apparatuses and methods provided herein are useful for dispensing a fluid, such as a thixotropic fluid. In some embodiments, a bottle having a closure cap includes a flip top, a base, and a disk, where the base and disk define a mixing chamber configured to facilitate mixing of any serum or liquid separated from the fluid back therein. In some configurations, the base has a central opening through which the fluid exits and an internal shaft with a non-planar end surface opposite the central opening. In some configurations, the non-planar end surface and the disk define channels between the mixing chamber and the internal shaft. In some embodiments, the disk includes a central opening, a plurality of partial annular openings through a planar surface of the disk, and projections extending into the mixing chamber.

A dispensing system may include a fluid container and a container receptacle. The fluid container may include a stacked arrangement of cross-slit valves through which a rigid projecting member of the container receptacle may be inserted through. Upon insertion of the rigid projecting member therethrough, fluid from the fluid container may flow into a tank of a 3D printing system through a dispensing channel of the rigid projecting member. The stacked arrangement of cross-slit valves acts a partial seal around the rigid projecting member, preventing fluid from leaking out of the fluid container from the outer surface of the rigid projecting member, while at the same time allowing ambient air to flow into the fluid container so as to backfill the partial vacuum created by the dispensing of the fluid from the fluid container.

A valve for a lid of a fluid vessel includes a valve body having an adapter portion coupling first and second opposite ends of the valve body. The first and second ends are rotatably fixed to each other and have an angle formed therebetween. The adapter portion is configured to be rotatably coupled to the lid about a first axis. The first end of the valve body is configured to be coupled to a button for rotating the first end about the first axis. The valve includes a stopper coupled to the second end of the valve body and configured to cover an opening in the lid. The stopper is configured to be separated from the opening when the first end of the valve body is rotated in a first direction about the first axis.
