Description

[Detailed description of the invention] (Field of industrial application) This invention uses pressurized air from an air pressurizing pump to pump the liquid in the inner container contained in the liquid container body to the outside through a series of liquid pouring passages. This invention relates to a pump-type liquid container that can be poured into a liquid container.

(Prior Art) In a conventional general pump-type liquid container, the liquid supply port of the liquid container body is closed with a stopper, and an air pressurizing pump is installed above the stopper. Blowing pressurized air from the air pressurizing pump into the inner container through an air passage provided in the plug body,
The pressurized air allows the liquid in the inner container to be discharged to the outside through a series of liquid discharge passages. However, in such a conventional pump-filling liquid container, since the air pressurizing pump is provided directly above the stopper, there is a problem that the height of the entire liquid container becomes high.

In addition, some known pump injection type liquid containers utilize an annular space formed above the shoulder of the inner container to fill the annular space, as shown in Japanese Patent Application Laid-Open No. 61-48324, for example. There is a system in which an annular air pressurizing pump is installed to keep the height of the entire liquid container low, but in this known pump-filling liquid container, the air pressurizing pump and the inside of the inner container are There was a problem in that the series of communicating air blowing passages was complicated (the air pressurizing pump was connected through the lid body to the in-stop air blowing passage provided in the plug body).

(Purpose of the invention) In view of the above-mentioned problems with conventional pump-filling type liquid containers, the present invention makes it possible to keep the height of the entire liquid container low; An object of the present invention is to provide a pump-filling type liquid container that can simplify the configuration of a series of air blowing passages that communicate between an air pressurizing pump and the inside of an inner container even if the container is pressed down. It is.

(Means for achieving the object) The present invention blows pressurized air from an air pressure pump into an inner container housed in a liquid container main body, and uses the pressurized air to convert the liquid in the inner container into a series of liquids. In a pump-filling type liquid container capable of dispensing to the outside through a dispensing passage, the liquid supply opening of the inner container is made smaller in diameter than the body of the inner container, and a shoulder is provided at the top of the inner container; An air blowing hole is formed in the shoulder of the inner container separately from the liquid supply opening, and the air blowing hole is connected to the air pressurizing pump by an air blowing passage. There is.

(Function) The pump injection type liquid container of the present invention has an air inlet forming hole formed in the shoulder of the inner container in addition to the liquid supply opening, and the air inlet forming hole and the air pressurizing pump are connected to the air inlet. Since they are connected through a blowing passage, the air blowing passage does not need to be provided in the stopper that closes the liquid supply port. Therefore, it is no longer necessary to install the air pressurizing pump above the liquid supply closure plug, and the air blowing passage can be installed through the space above the shoulder of the inner container, which is relatively unused. can.
