A plurality of caps are provided each with a visual coding of color and/or indicia for use with different sizes of bottles at least in accordance with a height of the bottles from a closed bottom end to an open top end for engaging each of the caps. Each of the caps has a tube mounted to, or through, an aperture extending through a top closed end of the cap to extend a selected length enabling one end of the tube to reach or extend along an interior surface of the bottom end of any of the bottles of the height to which the cap is coded for use therewith. The other end of tube is extendable to a bioreactor container. Each of the caps has another tube or port to another aperture of the cap to provide an air vent with an optional air filtering device.

The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.

A protective cap for a dispenser for discharging pharmaceutical and/or cosmetic liquids. The dispenser has a liquid reservoir and a discharge opening through which the liquid can be dispensed into a surrounding atmosphere. The protective cap has at least one ventilation opening for establishing communication between an interior and an outer surrounding area, and a sterile filter which covers the at least one ventilation opening is arranged on the protective cap in order to reduce or prevent an introduction of microbes into the interior of the protective cap via the at least one ventilation opening.

Disclosed is a chemical container capable of discharging gas generated from a chemical by stably securing a discharge passage of the gas even when the posture or tilt of the chemical container is variously changed, i.e. when the chemical container is turned over or falls sideways, whereby it is possible to prevent an excessive increase in internal pressure of the chemical container due to generation of the gas. The chemical container includes a container body having a storage compartment configured to store a chemical, an exhaust port disposed at one side of the container body, the exhaust port being configured to connect the storage compartment and the outside of the container body to each other in such a manner that fluid movement therebetween is possible, an exhaust tube disposed in the storage compartment so as to be connected to the exhaust port in such a manner that fluid movement therebetween is possible, and an exhaust buoyancy unit. The exhaust buoyancy unit has a buoyancy body disposed in the storage compartment in the state of being connected to the exhaust tube so as to float on the chemical stored in the storage compartment, an exhaust channel provided inside the buoyancy body, the exhaust channel being configured to connect the storage compartment and the exhaust tube to each other in such a manner that fluid movement therebetween is possible, and a filter membrane coupled to the buoyancy body, the filter membrane being configured to transmit gas through the exhaust channel and to block the chemical, thereby preventing the chemical from passing therethrough.

A plurality of caps are provided each with a visual coding of color and/or indicia for use with different sizes of bottles at least in accordance with a height of the bottles from a closed bottom end to an open top end for engaging each of the caps. Each of the caps has a tube mounted to, or through, an aperture extending through a top closed end of the cap to extend a selected length enabling one end of the tube to reach or extend along an interior surface of the bottom end of any of the bottles of the height to which the cap is coded for use therewith. The other end of tube is extendable to a bioreactor container. Each of the caps has another tube or port to another aperture of the cap to provide an air vent with an optional air filtering device.

Disclosed are various embodiments of a bottle cap apparatus configured for dispensing fluids through a sealed channel. In one example, the bottle cap apparatus comprises a cap, an insert container, and a stem. The cap has a top platform with an aperture. The insert container has a first end and a second end. The first end has a first opening that is positioned adjacent to an underside of the top platform of the cap. The second end having a recessed bottom with a second opening. The stem having a platform between a first end and a second end. The second end of the stem is positioned within the recessed bottom of the insert container. The first end being extended through the aperture of the cap. A dispensing channel is formed from the components of the bottle cap apparatus and is configured to allow a fluid be extracted from a bottle.

A container assembly including, a carton base having a substantially planar bottom surface, a lid having a top surface and a plurality of sidewalls extending therefrom. The lid is releasably engaged with the carton base and forms an interior space when engaged with the carton base. The top surface of the lid includes: a plurality of raised platforms, each raised platform having a substantially planar top surface, and a plurality of channels extending between each of the raised platforms such that each of the plurality of channels continuously extends to a perimeter of the lid. Additionally, the carton base is formed of three distinct laminate layers, with at least one of the laminate layers including a resin and a board weight of 200 g/m.sup.2 to 300 g/m.sup.2.

A venting liner is connectable in fluid communication between a closure and an interior of a device for venting gas from the interior into the ambient atmosphere. The venting liner has a first fluid impervious and gas permeable outer layer, a second relatively rigid and substantially incompressible outer layer defining an open cell structure, and an inner foam layer defining an inner surface and an outer surface, a plurality of fluid-flow apertures spaced relative to each other, extending between the inner and outer surfaces, and forming substantially vertical fluid-flow paths through the inner layer. The first outer layer is in fluid communication with the interior of the device for venting gas through the interior of the first outer layer, substantially vertically through the apertures and, in turn, through the interior open cell structure of the second outer layer and into the ambient atmosphere.

A pouch or package (e.g., flexible package) having a containment compartment or chamber to securely seal and to segregate fine powders or other such products from another area of the package. A powder resistant sealable filter material is included between, or extending between edges of, opposing package panels. Water, or other liquids, can be added to the product through the material as this material allows liquid to pass through it to mix with the powder, but restricts passage of the powder back through.
