Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container injection port device for injecting a liquid such as oil into a container body such as an oil tank of a general-purpose engine or the like.

[Problems to be solved by conventional techniques and ideas] Conventionally, in order to prevent oil or fuel from leaking when injecting oil or fuel into a tank such as an oil tank or a fuel tank of a general-purpose engine, A saucer was attached around the injection port, or a funnel separate from the injection port was inserted into the injection port each time.

However, since the tray protrudes outside of the tank, it becomes a nuisance and has the problem of falling off or being damaged by vibrations from the engine or the like.

In addition, the funnel must be inserted into and removed from the injection port each time injection is performed, which causes problems such as poor workability, loss of the funnel when not in use, and adhesion of dust.

Therefore, in order to solve the above-mentioned problem, for example, Japanese Utility Model Application Publication No. 56-26626 discloses that an arm-shaped funnel is attached to the injection port in a supine position during injection, and when not in use, the funnel is inverted and placed in a lying position. A technique is disclosed in which the injection port is attached to an injection port and the injection port is closed with a stopper.

However, in the conventional example, it is troublesome to replace the funnel, and there is a risk that the operator's hands may get dirty during the work. Further, there is a problem in that liquid such as oil that adheres to the inner circumferential surface of the funnel during pouring flows down onto the upper surface of the tank when not in use, staining the tank and the like.

In addition, in Japanese Patent Application Laid-open No. 55-20129, it is usually stated that
It is stored in the injection port in a cylindrical shape, and when injecting liquid,
A retractable funnel is disclosed that can be pulled out and expanded into a fan shape.

However, in this conventional example, since the funnel is stored inside the injection port, liquid such as oil adheres to the outer circumferential surface of the funnel when it is stored, and when the funnel is pulled out, this adhered liquid flows down, staining the tank etc. There is a problem of being exposed.

[Purpose of the invention] The present invention has been made in view of the above-mentioned matters, and is intended to facilitate the work of injecting liquid such as oil into an oil tank, etc., and also to prevent it from getting in the way, being lost, or being damaged when not in use. To provide an injection port device for a container that is not exposed to liquid or contaminated, and does not stain the container body or an operator.

[Means and effects for solving the problem] In order to achieve the above object, the container inlet device according to the present invention includes a retractable funnel-shaped guide provided at the inlet of the container body into which liquid is placed, and this funnel-shaped guide. In a container inlet device having a lid for closing an opening of a guide, the funnel-shaped guide and the lid are integrally formed, and the funnel-shaped guide includes:
When extended, it expands into a funnel shape and maintains its extended state, and when contracted, it is folded toward the inlet with the inner peripheral surface kept inside, and the plug formed on the lid fits the diameter of the inlet. The contracted state is maintained by being inserted into the container.

That is, when injecting oil or the like into a container body such as an oil tank, it is possible to expand the funnel-shaped guide into a funnel shape, open the opening, and inject the oil or the like from this opening. In addition, normally, the opening is closed by the lid, the funnel-shaped guide is folded toward the injection port with its inner circumferential surface kept inside, and the funnel-shaped guide is formed on the lid. A stopper is fitted into the diameter of the injection port so that the contracted state is maintained without exposing the inner circumferential surface to which oil or the like has adhered.

Next, the operation of this embodiment with the above configuration will be explained.

First, in a normal state, as shown in FIG. 2, the funnel-shaped guide 7 is in a contracted state, and the convex portion 8d of the lid 8 is fitted into the opening 7b of the funnel-shaped guide 7. Furthermore, the protruding stopper 8b is fitted into the injection port 6 to close it.

Next, when injecting oil 0 into the oil tank 4, first insert the convex portion 8d of the lid body 8 into the funnel-shaped guide 7.
The projecting stopper 8b is pulled out from the injection port 6 while it is fitted into the opening 7b. Then, the guide 7 expands into a funnel shape. Thereafter, the convex portion 8d of the lid body 8 is removed from the opening 7b of the funnel-shaped guide 7, and the convex portion 8d of the lid 8 is removed from the opening 7b.
Open the bottle. The funnel-shaped guide 7 is maintained in an extended state by its own elastic force, and in this state, oil 0 can be injected into the oil tank 4.

After the injection of oil 0 is completed, the convex portion 8 of the lid body 8
d into the opening 7b of the funnel-shaped guide 7 to close the opening 7b, and then the lid 8 is pressed. As a result, the approximately central portion of the side surface portion 7c of the funnel-shaped guide 7 bulges outward, so that the funnel-shaped guide 7 is folded toward the injection port 6 side while keeping the inner circumferential surface of the side surface portion 7c inside, and is not susceptible to external force. The contracted state is maintained without twisting. Further, the protruding stopper 8b of the lid body 8 is inserted into the injection port 6 and the stopper is closed.

Further, in this embodiment, the funnel-shaped guide 7 is configured to contract by expanding the substantially central portion of the side surface portion 7c outward, but the side surface portion 7c may be folded multiple times. , or may be formed in advance into a bellows shape.

In addition, in this embodiment, the funnel-shaped guide 7 is maintained in the contracted state without any external force; The state may be maintained.

Further, the shapes of the guide 7 and the lid 8, the method of attaching the guide 7 to the injection port 6, etc. are not limited to those of this embodiment.

Further, the container inlet device of the present invention is not limited to the inlet of an oil tank, but can be applied to the inlet of various container bodies such as a fuel tank and a cooling water tank.

[Effects of the invention] As explained above, according to the invention, when injecting liquid, the funnel-shaped guide is extended,
All you have to do is open the opening, and since the worker does not have to directly touch the inner surface of the funnel-shaped guide that has oil or other liquid on it, the worker will not get dirty and the work will be easy. This has the effect of making it easier.

Further, in a normal state, the funnel-shaped guide is attached to the tip of the injection port in a contracted state, so the funnel-shaped guide does not get in the way or get lost.

In addition, the inner circumferential surface of the funnel-shaped guide is always kept inside, so that liquids such as oil attached to the inner circumferential surface do not flow to the outside. Since it is kept in a contracted state externally and liquid such as oil does not adhere to the outer circumferential surface and run off, the operator and the container body are not contaminated.

Further, in a normal state, the funnel-shaped guide is closed, and the inner circumferential surface is not soiled by dust or the like.

In addition, since the funnel-shaped guide and the lid are integrally formed, the lid will not be lost when injecting liquid, making it easy to handle.

Furthermore, since the plug formed on the lid is fitted into the aperture of the injection port to maintain the contracted state of the funnel-shaped guide, the lid can be pushed in after contacting the funnel-shaped guide. The funnel-shaped guide and the injection port can be closed with a single touch, which not only improves workability but also allows the injection port to be directly blocked to prevent liquid from leaking.
