Abstract: A nasal seal, mask or an interface assembly have a seal body defining a breathing chamber. A nasal port is provided in the seal body. The nasal port has a central portion straddled by a pair of lateral portions. The nasal port further has an upper edge and a lower edge. The upper edge defines an inwardly projecting portion within the central portion. The lower edge defines an inwardly protection portion within the central portion. Thus, the nasal port can be generally bean-shaped or bowtie-shaped. The mask can include a frame having a central portion that supports the seal and a pair of arm portions that extend rearwardly of the seal and are configured to connect to headgear. The central portion can be more rigid than the arm portions. The mask can be configured to reduce noise transmitted through a bias flow vent.

Abstract: An interface for positive pressure respiratory therapy includes a mask assembly having a mask seal and a mask shell. The mask assembly is positioned lower than and exposes a bridge of the user's nose. The mask seal includes first and second portions on respective first and second sides of a nasal region that contact opposing sides of the user's nose. The first and second portions each include supports that help maintain a shape of the mask seal. A pair of covers can be supported relative to the mask assembly and adjacent a respective one of the first and second portions of the mask seal. The covers limit expansion of the first and second portions of the mask seal in response to pressurized air within the mask seal. The supports of the first and second portions can transfer load from the mask seal to the covers.

Abstract: A nasal seal for a respiratory interface comprises a supple lower-nose-receiving center part having a concave shape pre-formed to receive and sealingly contact the tip, lower sides, and base of the nose and sealingly contact the upper lip, and position an aperture for gas flow beneath the nares of wearer. The seal may have resilience or memory towards this preformed shape.

Abstract: A vegetable bin (4) or a refrigerator comprises a floor, enclosing side walls and a substantially open top. The vegetable bin is placed within a refrigerated space beneath a lower shelf (6) to be cooled. The vegetable bin is furt provided with a lid (5) to cover said open top, and said lid is suspended underneath the lower shelf directly above t vegetable bin. In one condition the lid substantially seals the vegetable bin to help keep the vegetables fresh. In another condition the lid is lifted up a small amount at a rear portion of the lid, by operating control means (11), in order to allow the air within the vegetable container to exchange with the air of the refrigerated space. The air pathway is opened between the lid and the upper perimeter of the vegetable bin and is preferably located toward th rear of the refrigerated space proximate a circulating fan (8).
