Description

[Detailed description of the invention] The present invention is capable of continuously pouring out liquid in a liquid container by the pumping action of a pump device and the siphon action of a series of liquid pouring passages that communicate inside and outside the liquid container. This invention relates to a siphon-type liquid container.

In conventional siphon-type liquid containers of this type, the pump device is operated by a pump pusher plate that can be slid up and down in a sliding hole provided in the center of the lid, while a series of liquid A valve body that opens and closes an air introduction hole for draining water to the pouring passage is opened and closed by operating the pump push plate.

By the way, in order to maintain the valve body for opening and closing the air introduction hole in the closed state when dispensing liquid, it is necessary to keep the pump push plate pressed. In conventional siphon-type liquid containers,
Since the presser plate pressing position is directly above the pump action position, a large holding force is required to hold the pump presser plate in the depressed state, and in the pump presser plate type, the above-mentioned valve body can be installed within the range. is narrow (limited to just below the pump push plate), and the structure is complicated because there are liquid supply port plugs, air blowing passages, etc. directly below the pump push plate, and the drain valve body and its The structure was further complicated by the provision of an operating mechanism.

The present invention was made with the aim of improving the problems of the conventional siphon-type liquid container described above. In a siphon-type liquid container capable of continuously dispensing to the outside by a siphon action of a passage, one end side is pivotally connected to the rear end of the lid body as a pump pushing device for pushing and driving the pump device. A push lever is used whose end side is an operating portion on the front side of the lid body, and the other portion of the push lever other than the operating side end is built into the lid body,
Further, a valve body for opening and closing the air introduction hole of the liquid pouring passage is provided below the operation side end of the push lever so that the valve body is opened and closed by the operation side end when the push lever is pressed. It is said that

According to the siphon type liquid container of the present invention, the following effects can be obtained. That is, since the valve body for opening and closing the air introduction hole is provided below the operating end of the push lever whose one end side is pivotally connected, the holding force of the push lever when the push lever is pressed down (valve closed state) is reduced, and the valve The degree of freedom in the installation position of the push lever is increased, and since one end of the push lever is plugged to the rear end of the lid body and the other end is used as the operation part on the front side of the lid body, it can be used as the pump operation part when dispensing liquid. The liquid dispensing part is closer, making it easier to perform liquid dispensing work.Furthermore, since the push lever except for the operating end is built into the lid, there are fewer parts of the push lever that protrude outside the lid. Become.

An embodiment of the present invention will be described with reference to FIGS. 1 to 8. In the siphon type liquid container of the embodiment shown in FIG.
