A water bottle with a pressurized compartment and an unpressurized compartment to integrate supplemental oxygen delivery into a hydration and electrolyte management system. The unpressurized compartment may be manually filled with a fluid. The user may consume fluid from the unpressurized compartment and an aerosol from the pressurized compartment independently or simultaneously.

This disclosure relates to a cosmetic composition capable of preventing enzyme damage, and a cosmetic container for storing the same. One aspect of this disclosure provides a cosmetic composition capable of preventing enzyme damage, the composition including a first content disposed in a first space; a second content which is disposed in a second space separated from the first space, and which includes an enzyme and a polyol, wherein a cosmetic material is produced by mixing the first content and the second content.

A pre-filled medical delivery system can have a blow-fill-seal (BFS) component and a connection assembly. The BFS component can have first and second chambers, and first and second sealed ports. Each chamber can have a respective liquid agent therein. Each sealed port can be in fluid communication with a respective one of the chambers. The connection assembly can be constructed for coupling to the BFS component. When coupled to the BFS component, the connection assembly can breach the seals of the first and second ports and provide fluid communication therebetween. The disclosed systems, when assembled, can combine the liquid agents from the first and second chambers of the BFS component and deliver the combination as a single dose of a therapeutic agent (e.g., vaccine, drug, medicament, etc.) to a patient.

The present disclosure describes a cup system for simultaneous delivery of contents from separated cups to a mouth of a user. The cup system includes an outer cup, an inner cup, a lid, and a cap. The outer cup includes an upper lip with a threaded surface configured to engage with a mating threaded surface of a lid. The inner cup includes an engaging lip configured to engage with a lower inner lip and configured to form a seal between the inner cup and the lid, as well as a flange located below the engaging lip that extends outward from a periphery of the inner cup. The lid includes an outer wall with a lower outer lip comprising the mating threaded surface, the mating threaded surface is configured to engage with a threaded surface. The cap includes a mating engagement feature configured to engage with an inner wall engagement feature.

A bottleneck insert having a cylindrical body; a tube located inside the cylindrical body, wherein the tube is coaxial with the cylindrical body and extends through along the cylindrical body, end wherein the tube is connected to a side wall of the cylindrical body via a base located at a first end of the side wall of the cylindrical body; and a sieve having a form of a circular ring and located between the tube and the side wall of the cylindrical body.

A multi container assembly comprising, a first container having an opening with a first securing means distal to the opening and integrated within an internal cavity of the first container and a protrusion extends upwards towards the opening and a second securing means is disposed on the protrusion, a second container wherein the first end has an opening and a first securing means distal to the opening and a second securing means distal to the second end, and a cap having a first securing means designed to mate with the first securing means of the first container and a protrusion extending downward from the internal cavity, wherein the protrusion has a second securing means designed to mate with the first securing means of the second container, wherein when the cap is secured to the first container and the second container a substantially impervious seal is formed.

A dispensing device for dental material, which includes a planetary gear drive with at least three planet gears in engagement with an annulus gear. The annulus gear is radial float-mounted relative to the planet gears. A radial force applied on the annulus gear urges the annulus gear into an off-center relationship with respect to an imaginary circle on which the planet gears are arranged.

Various embodiments of the present disclosure provide a cartridge for dispensing two-part fluids. In one embodiment, the cartridge comprises a cartridge body having a dispensing end and defining a first fluid reservoir and a second fluid reservoir. The dispensing end defines at least one aperture fluidly connected to the first fluid reservoir. The dispensing end also defines a dispensing conduit fluidly connected to the second fluid reservoir. The cartridge further comprises a nozzle member engageable with the cartridge body to form an outlet and to fluidly connect the at least one aperture to the outlet.

A dual chamber bottle includes a doser for mixing and dispensing two liquids. The bottle holds a first bulk liquid in a bulk chamber. The bottle holds a second additive liquid in a cartridge. The first and second liquid are segregated from each other. The doser is provided to dose the additive liquid into the bulk liquid. The second liquid is an additive that enhances a quality of the first liquid. The bulk chamber can be squeezed to dispense the bulk liquid out of the bottle while introducing the additive liquid to the bulk liquid in the process of dispensing.

An assembly for mixing and dispensing a multi-component fluid includes a sheath having first and second fluid chambers, a chamber coupler, and a flexible tip. The chamber coupler forms first and second fluid channels. Additionally, the flexible tip forms a mixing chamber with a variable mixing volume and an outlet. The flexible tip is coupled to the chamber coupler near a distal end of the sheath. In the presence of an activation force, the flexible tip is forced out of the sheath and positioned in a dispensing state with a maximum mixing volume. In the absence of the activation force, the flexible tip is housed within the sheath and positioned in a non-dispensing state with a minimum mixing volume such that the outlet is substantially closed.
