A product information providing apparatus is connected to a product information management apparatus having product information management data. The product information providing apparatus is capable of bidirectional communication via a communication network to a remote terminal, and includes receiving means for receiving from the remote terminal a request command requesting transmission of product information management data concerning a specified product via the communication network. Also, the product information providing apparatus includes obtaining means for obtaining from the product information management apparatus, in response to the request command, the product information management data concerning the specified product. The product information providing apparatus further includes transmitting means for transmitting to the remote terminal the obtained product information management data concerning the specified product.
摘要:
In accordance with the present invention, a liquid agent container includes the container's main unit, a cap, an intermediate member, and an internal stopper. The cap is provided with a liquid agent discharging path and an air introducing path. The intermediate member has a tube projecting toward the interior of the main unit. Between a liquid agent introducing path and the liquid agent discharging path a hydrophilic filter is provided, and between an air supplying path communicating with the air introducing path and an air delivering path a filter is provided. The air delivering path communicates with the interior of the main unit via a check valve, with an annular valve having an inner circumferential surface in contact with an outer circumferential surface of the tube, to pass air only in a direction toward the interior of the main unit. The present invention can provide a liquid agent container including a check valve readily fabricated and ensuring preventing a liquid agent from flowing back.
