Benefits of technology

Specifically, the ring-shaped protrusion is formed on the outer periphery of the nozzle portion to prevent dripping from the nozzle portion and allow a droplet to be adequately formed irrespective of a posture (instillation angle) of the container body to improve instillation performance. The above structure is fr

Problems solved by technology

However, in the container described in JP 10-329855A, during the cap attaching operation, a nozzle portion is guided while being brought into contact along a guide portion provided on the cap, so that repetition of the cap attaching/detaching operations would be likely to cause deformation or the like in the nozzle,

Example

FIGS. 1 and 2 illustrate a substantial part of a liquid container according to the present invention.

The liquid container (hereinafter abbreviated as “container”) illustrated in FIGS. 1 and 2 is a so-called twist cap-type container. In this embodiment, this container is an eye drop container which comprises a container body 1 having a nozzle portion 14, and a cap 2 detachably attachable to the container body 1 to cover the nozzle portion 14, wherein it is designed, during instillation, to allow a medical solution contained in the container body 1 to be instilled from a tip end of the nozzle portion through an operation of gently pressing the container body 1 while orienting the tip end of the nozzle portion downwardly under a condition that the cap 2 is detached.

As shown in FIG. 1(b), the container body 1 is formed in a flat shape in a forward-rearward direction (upward-downward direction in FIG. 1(b)). The container body 1 is configured such that a circular tubular neck portion 12 ...

Abstract

A liquid container has a body (1) and a cap (2). A circular tubular neck (12) of the body (1) has an outer diameter greater than a maximum diameter of a nozzle (14), and a locking protrusion (124) for the cap (2) is provided on an outer peripheral surface of the circular tubular neck. The cap (2) has two lockable arms (24). The lockable arms (24) are locked onto the locking protrusion (12a) while attaching the cap (2) to the body (1). Opposing surfaces (26) of the lockable arms (24) define guide surfaces that contact the outer peripheral surface of the circular tubular neck (12) during the cap attaching operation to guide the cap (2) along the circular tubular neck (12) so as to allow a plug protrusion (22) of the cap (2) and a nozzle hole (14a) to oppose each other.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a liquid container useful as a container for an eye drop (ophthalmic solution), a nose drop (nasal solution), a contact-lens cleaning solution or the like.2. Description of the Related ArtHeretofore, as a container for an eye drop or the like, there has been commonly known a type which comprises a container body having a nozzle, and a cap detachably attachable to the container body, wherein it is designed to allow a medical solution to be instilled (dropped) from a tip end of the nozzle through an operation of gently pressing the container body while orienting the tip end of the nozzle downwardly under a condition that the cap is detached.Particularly, a so-called twist cap-type liquid container having a lockable arm provided on an inner peripheral surface of a cap is widely used as the container for an eye drop or the like, wherein it is designed such that the cap is attached to a container body by...
