  • Patent number: 9308150
    Abstract: 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.

  • Publication number: 20130149394
    Abstract: The invention provides an aqueous ophthalmic composition, containing a beta blocker such as timolol, carteolol or the like, and a sugar alcohol such as mannitol, sorbitol or the like, optionally together with boric acid. The composition of the invention can improve the corneal permeability of a drug, so that the dose of the drug can be lowered, for example by decreasing the frequency of application to the eyes. It is therefore expected that the risk of systemic side effects which may be induced by the application of the beta blocker to the eyes, including cardiotoxicity or respiratory toxicity can be reduced. The decrease in the frequency of application of ophthalmic solution can favorably improve the QOL and prevent the decrease of therapeutic effect which may be caused by missing the application to the eyes.
