Description

  The present invention relates to an eye drop container used for containing and dropping an eye drop. Priority is claimed on Japanese Patent Application No. 2013-142184, filed July 5, 2013, the content of which is incorporated herein by reference.

  Generally, an eye drop container includes a liquid reservoir (also referred to as a "container main body") for storing eye drops, a pouring nozzle for dropping the eye drops, and a cap for closing the storage container. The pouring nozzle of the container for eye drops has a projecting shape with a certain length so that the eye drops contained in the storage container can be dropped in a state where the container is inclined. In addition, the cap has a sealing means constituted by, for example, the top surface itself or a plug member provided on the top surface. The sealing means seals the tip of the pouring nozzle by pressing down the tip of the pouring nozzle, inserting it into the tip of the pouring nozzle, or combining these means, assuring liquid tightness. doing.

As a cap which is a closure member of a storage container, there is a separation type cap such as a twist type cap. In addition, in order to further improve usability, a hinge-type cap or the like which can be opened and closed with a single hand is known (for example, Patent Document 1).
The liquid tightness of the eye drop container by the cap generally causes the tip of the dispensing nozzle to engage with the plug member provided on the cap, and a liquid tight portion (i.e., a seal) between the tip of the dispensing nozzle and the plug member. It is secured by forming an area). For example, in the case of an eye drop container using a separation type cap movable in the up and down direction, the sealing means (also referred to as a plug closing portion) provided on the cap and the tip of the pouring nozzle move up and down relative to each other As a result, liquid tightness is secured. In the liquid-tight section, when the cap is put on, the liquid-tightness of the liquid-tight section may change as the engagement state between the tip of the pouring nozzle and the plug member may change. Therefore, in order to improve the liquid tightness of the eye drop container, the liquid tight portion needs to be formed with a sufficient dimension in the direction to follow the moving direction of the cap.

Japanese Patent Application Laid-Open No. 2002-362603
