Problems solved by technology

However, in order to prevent negative pressure from being generated in the conventional discharge container, it is necessary to install an automatic piston, etc., and it is obvious that the structure becomes complicated.
In addition, although it is also considered that introducing external air into the container can also prevent the negative pressure in the container, it is also possible that bacteria and external air will enter the container at the same time.

Embodiment Construction

[0020] Refer below Figure 1 to Figure 3 , The specific embodiments of the present invention will be described.

[0021] The discharge container 1 of this embodiment is as figure 1 (a) and figure 1 As shown in (b), there is a main body 3 containing the liquid medicine 2 and a top cap 4 provided above the main body 3. In addition, below the inside of the main body 3, a cylindrical cylinder 5 is integrated with the main body 3 in the vertical direction, and a slidable cylindrical piston 6 is provided inside the cylindrical cylinder 5. The piston 6 is connected to the top cap 4 via a hollow center shaft 7 penetrating the upper part of the main body 3, and the vertical movement of the top cap 4 is transmitted to the piston 6 through the center shaft. As a result, in the discharge container 1 of the present embodiment, the top cap 4, the center shaft 7, and the piston 6 are connected in a substantially linear unit. In addition, the center shaft 7 protrudes upward from the main body 3....

Abstract

A delivery container (1) capable of surely delivering a specified amount of liquid with a simple structure, comprising a main body (3) filled with a chemical (2) and a cap (4) installed on the upper side of the main body (3), wherein a barrel (5) having a slit (11) is formed on the inside lower side of the main body (3) integrally with the main body (3), a cylindrical piston (6) having a check valve (12) is installed slidably in the barrel (5), the piston (6) is connected to the cap (4) having a delivery port (4a) through a hollow shaft (7) passing through the upper part of the main body (3) so that the vertical movement of the cap (4) is transmitted to the piston (6) through the shaft (7), the chemical (2) made to flow into the cylinder through the slit (11) by gravity being filled into the cylinder (5) at all times because the barrel (5) is provided at the bottom part of the main body (3), whereby the chemical (2) need not be sucked and the specified amount of chemical (2) is delivered from the delivery port (4a) at all times.

Description

Technical field [0001] The present invention relates to a discharge container in which liquid such as a liquid medicine or a gel-like fluid is discharged by the principle of a pump. Background technique [0002] Hitherto, the publication of Japanese Patent Laid-Open No. 5-319466 as a discharge container for discharging liquids such as liquid medicines or gel-like fluids has been well known. Such a traditional discharge container is provided with a pump part above the container that sucks the liquid up from the container. The pipe extending from the pump part to the bottom sucks the liquid to the pump part, and then discharges it through the discharge port provided above the pump part. liquid. [0003] In the discharge container of Japanese Patent Laid-Open No. 5-319466, a ball-type check valve that functions as a check valve is provided below and above the pump part. When the pump is pressed, the piston in the pump presses the liquid that is replenished in the pump. As a result, ...
