Definitions
- the present invention relates to a fluid container and an airless fluid administration system using the same.
- Airless fluid administration systems are used in various applications to administer or apply fluids containing pharmaceuticals such as nasal sprays, quasi-drugs such as hair restorers, and cosmetic fluids such as perfumes to application sites. Has been used.
- an airless container with a pump described in Patent Document 1 includes a container body that holds fluid and an airless pump.
- the airless pump pressurizes the fluid stored in the suction chamber when the nozzle is pressed and releases it into the atmosphere to release the sprayed fluid from the nozzle force, and the airless pump returns upward.
- it is configured to suck the retained fluid from the container body into the suction chamber (see FIG. 2).
- the container body is provided with a bottom lid that is slidable with respect to the side wall and pressed to atmospheric pressure, and the bottom lid slides upward due to negative pressure generated when fluid is sucked into the suction chamber. It is configured as follows.
- a pump-type product using the content discharge mechanism described in another Patent Document 2 basically has the same configuration as that of Patent Document 1, but between the container main body and the bottom when the user completes use.
- the problem was that unused fluid remained in the annular space and that air remained in the annular space between the container body and the bottom when the manufacturer filled the fluid. If air remains in the annular space, that is, in the container body, do not put it into actual use before the user uses it.
- the fluid force also needs to exclude air. Otherwise, the amount of fluid used may vary, and inconveniences may arise, especially when a predetermined amount of fluid needs to be administered, such as when the fluid is a pharmaceutical product.
- Patent Document 2 provides a substitute ceiling having a flat lower surface in the annular space of the container body, thereby preventing the remaining of unused fluid at the completion of use and air mixing at the time of fluid filling. (See Figure 1).

However, minute air still remains on the flat lower surface of the substitute ceiling during fluid filling. Adhering was unavoidable, and unnecessary bombing operation was similarly forced to eliminate this residual air. In other words, the substitute ceiling of Patent Document 2 was not sufficient as a means for preventing air from remaining in the container body when the fluid was filled. Therefore, it has been desired to realize a container body that can be more easily and reliably excluded even when air enters the container body. Note that Patent Document 1 describes only improving the slidable lid, and does not mention anything about eliminating residual air.

- Each of the spacer and the sliding valve has a spacer surface and a valve surface facing each other, and the spacer surface and the valve surface are 5 to 3 degrees with respect to a horizontal plane.
- the spacer surface and the valve surface are complementary to each other.
- the side wall and the spacer of the container body may be integrally formed.
- the spacer surface and the inner surface of the side wall may be configured to be substantially continuous via a curved surface.
- the spacer may be formed of a low-density polyethylene cover or may be formed using an elastic material.
- the angle formed by the spacer surface with the horizontal plane may be larger than the angle formed by the valve surface with the horizontal plane.
