Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a liquid container with a lid, such as a pump-filling type liquid container, and more specifically, to a liquid container with a lid detachably attached to the liquid container body. It concerns containers.

(Prior art) In a liquid container with a lid, such as a pump-filling type liquid container, during normal use, the lid is pivoted to the liquid container body so that it can be opened and closed in an arc, and the residue inside the liquid container body is It is convenient to remove the lid from the liquid container body when draining the liquid or cleaning the inside of the liquid container body.

Incidentally, as an example of a liquid container in which a lid body is detachably attached to a liquid container main body in this manner, a liquid container as shown in FIG. 8 has been known (Japanese Utility Model Publication No. 3345/1983). The known liquid container shown in FIG. 8 has a lower hinge stand 191 provided on the liquid container body 101 side and an upper hinge stand 1 provided on the lid body 102 side.
95 on the upper hinge stand 195 side.
97 to pivot the lid 102 to the liquid container body 101.
A notch 19 is attached to the lower hinge base 191 so that the hinge pin 197 can be opened and closed in an arc.
3 through the pin pivot portion 192 of the lower hinge stand 191
By making it possible to insert or remove the
The lid body 102 can be freely separated from the liquid container body 101. The lid body 102 moves from the fully closed state shown by the solid line to the liquid container main body 101 to the chain line 1.
It is designed to be able to open and close steplessly within the range of the fully open state indicated by 02'. In addition, a notch 193 provided in the lower hinge stand 191 for fitting and removing the hinge pin is formed in an L shape that opens upward. When removing the lid from the pivot part), hold the lid 102 in your hand with the lid locking device (not shown) unlocked and open it by a predetermined angle (for example, about 30 degrees), and in that state, first move the lid 102 forward. The hinge pin 197 can be removed from the pin pivot portion 192 by moving the hinge pin 197 upward and then lifting it upward.

(Problem to be solved by the invention) However, in the known liquid container shown in FIG.
Although the lid can be separated from the liquid container body, when separating the lid from the closed state, first hold the lid at a specified angle with the lid locking device unlocked. There was a problem in that the lid had to be rotated in an arc upwards, making the operation to open the lid cumbersome.

Incidentally, some of the known liquid containers include, for example,
- As shown in Publication No. 201639, a spring that biases the lid toward the open side is wrapped around the hinge pin of the hinge device, and when the lid locking device is unlocked, the lid is moved by the biasing force of the spring. It is known that the lid is of a non-separable type, and a spring for opening the lid is attached to the hinge pin in this known example. With such a structure, it is difficult to create a structure in which the hinge pin can be separated from its pivot portion.

In view of the above-mentioned problems when removing the lid of a liquid container, the present invention makes it possible to easily remove the lid of a liquid container in which the lid is removably pivoted to the liquid container body. It was done for that purpose.

(Means for Solving the Problems) The present invention is a liquid container in which a lid body is pivoted to a liquid container body by a hinge device so as to be able to open and close in an arc, and the lid body is detachable from the liquid container body. In the container, a lid opening is provided between the shoulder member of the liquid container body and the lid body, and at a position near the lid opening side of the hinge device, for opening the lid body by a predetermined angle with respect to the liquid container body when the lid locking device is unlocked. It is characterized by the provision of a mechanism.

(Function) According to the liquid container of the present invention, when the lid locking device is unlocked, the lid opening mechanism automatically opens the lid by a predetermined angle. It can be removed from the liquid container body. In addition, since the lid opening mechanism is provided near the hinge device between the shoulder member and the lid, the lid can be rotated in a large arc even if the amount of lid pushing up of the lid opening mechanism is small. In addition, the lid opening mechanism can be provided using the space between the shoulder member and the lid, and the lid opening mechanism does not get in the way when the lid is attached or removed.

(Effect of idea) The liquid container of the present invention has the following effects.

(1) Removal of the lid from the liquid container body is performed with the lid open; however, with the present invention, the lid can be automatically opened simply by unlocking the lid locking device. A series of operations for removing the lid becomes easy.
