Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hinge device for a container with a lid, in which the lid body is removably attached to the container body.

(Prior Art) As an example of a hinge device for a lidded container in which the lid is removably attached to the container body, the one shown in Fig. 1 (for example, a pump injection pot) is known. However, in this conventional hinge device for a container with a lid, the hinge pin 30 attached to the hinge portion 21 on the lid body 2 side can be freely inserted and removed into the pin support member 81 pivotally attached to the hinge portion 11 of the container body 1. The lid body 2 is configured to be removably attached by fitting into the housing. A pin fitting groove 82 that opens inward is formed in the upper part of the pin support member 81, and when the lower part 81a of the pin support member 81 is pushed inward, the pin fitting groove 82 portion tilts outward. The hinge pin 30 can be fitted into and removed from the pin fitting groove 82, thereby making it possible to attach and detach the lid body 2.

However, this conventional hinge device has the following problems.

(1) The hinge pin 30 on the lid 2 side is connected to the main body side hinge part 11
Since the lid body 2 is supported by a pin support member 81 which is pivotally connected to the hinge pin, the lid body 2 tends to wobble, and the pin support member 81 releases the hinge pin lock when a large impact is applied to the lid body 2. The lid body 2 is easily moved in the direction of the container body 1 or the pin lock support member 81 is damaged.
It becomes easy to come off inadvertently.

(2) The pin support member 81 is designed so that the hinge pin 30 is unlocked by pushing its lower part 81a inward, so that, for example, when this container with a lid is tipped backwards, The pin support member 81 may collide with the floor or the like and be unlocked, and in that case, the lid 2 will come off.

(3) As mentioned in 2 above, the pin support member 81 is unlocked by pushing its lower part 81a inward in the horizontal direction.
When the pin support member 81 is pressed when the hinge pin lock is released when removing the lid 2, a pressing force is applied horizontally from the rear side to the front side against the container with a lid, and if left as is, the pressing force will Since the lidded container is tipped forward, it is necessary to support the front side of the container with another hand, making the hinge pin lock release operation troublesome.

(Purpose of the invention) In view of the above-mentioned problems with conventional hinge devices, the present invention can reliably support the hinge pin provided on the lid side hinge, thereby preventing the lid from accidentally coming off. It is an object of the present invention to provide a hinge device for a container with a lid, which prevents this from occurring and also facilitates the operation of releasing the hinge pin lock when removing the lid.

(Means for Achieving the Purpose) The present invention attaches the lid to the container body by removably fitting the hinge pin provided on the lid side hinge into the body side hinge provided on the upper part of the container body. In a hinge device for a container with a lid that is removably attached to a container with a lid, the hinge pin is composed of two divided pins arranged opposite to each other, and each of the divided pins is inserted into and removed from the hinge portion on the main body side. A pin fitting groove is formed for free fitting, and a pair of left and right pin lock members are provided on the main body side hinge portion to be displaced by pinching and operating from both sides in the left and right direction, and the pin lock members include: A locking mechanism that displaces between two positions, a pin lock position where each divided pin fitted in the pin fitting groove is engaged and locked, and a pin lock release position where each divided pin is unlocked in accordance with the displacement of the knob operation. It is characterized by the provision of a joint.

(Example) Hereinafter, the hinge device for a container with a lid of the present invention will be explained with reference to the examples shown in FIGS. 2 to 4.
In the illustrated embodiment, a liquid container (for example, a pump injection pot) is used as the container with a lid.

First, the basic configuration of the hinge device 3 of this embodiment will be explained. This hinge device 3 has a container body 1.
