Description

The present invention relates to a new fuel carrying can, and more specifically, even if the internal pressure rises due to the volatilization of volatile fuel inside the carrying can, the excessive pressure can be released to the outside, and high safety is achieved. Regarding fuel carrying cans that can be demonstrated.

Since volatile fuel has a low flash point, it is moved and stored after being injected into a storage container such as a dedicated carrying can made of metal or the like.

FIG. 3 shows an example of a typical fuel carrying can. As shown by the number 50 in FIG. 3, the carrying can container portion 51, the lid portion 52, the air adjusting screw 53 and the lid portion 52, which are generally made of metal or the like, are removed and connected to the opening for use. It is composed of a hose 54 and the like.

Here, among the volatile fuels, gasoline has a flash point of 35 to 46 ° C. and an ignition point of 400 to 500 ° C., and may vaporize even at −40 ° C. or lower. Then, the internal pressure of a storage container such as a carrying can rises, and there is a risk of discharging during use.
Therefore, it is necessary to release the excessive internal pressure to the outside by loosening the air adjusting screw provided on the top surface (upper part) of the carrying can and then removing the lid.

On the other hand, because the work of loosening the air adjustment screw was neglected, the vaporized or misted gasoline was ejected to the outside and ignited by static electricity, causing a fire accident and in some cases, the loss of human life. There is no end to it.

Various types of fuel carrying cans have been developed. For example, in Patent Document 1, "a blow having a discharge port arranged at one end of the top surface and an upward protruding portion having the upper end of the protrusion as a receiving portion at the time of stacking at a required position on the top surface. It is a molded carrying can
The side wall on the discharge port side of the protruding portion is tilted at a large angle with respect to the height direction of the carrying can so that the upper portion of the side wall is located on the end side opposite to the discharge port side on the top surface. "Characteristic carrying can" is disclosed (claims).

FIG. 1 is an overall view for explaining one aspect of the fuel carrying can according to the present invention.

FIG. 2 is a cross-sectional view for explaining the structure of the lid portion of the fuel carrying can according to the present invention.

FIG. 3 is a diagram for explaining one aspect of a conventional fuel carrying can.

Hereinafter, the fuel carrying can according to the present invention will be described in detail with reference to the drawings as appropriate.

Reference numeral 1 in FIG. 1 shows an aspect of the fuel carrying can according to the present invention. As shown in FIG. 1, the fuel carrying can 1 has a carrying can container portion 10 and a lid portion 20 as essential constituent requirements. As an arbitrary configuration, as shown in FIG. 1, a hose 30 used by connecting to the opening and an air adjusting screw 40 for reducing the internal pressure may be provided.

The constituent materials of the fuel carrying can are not particularly limited, and can be appropriately selected in consideration of the type of fuel to be held, laws and regulations, and the like. For example, it may be made of metal such as iron such as stainless steel, or may be made of plastic such as polypropylene. When the fuel is gasoline, it is preferably made of metal. In the fuel carrying can according to the present invention, the fuel is not particularly limited, and examples thereof include volatile fuels such as gasoline, light oil, and kerosene.

As shown in FIGS. 1 and 2, the carrying can container section 10 includes a container port 11 for injecting and discharging volatile fuel, and a fuel storage section 12 which is a space for storing (preserving) the injected fuel. A male screw portion 13 is formed around the container mouth portion 11 in order to screw the lid portion to be described later.
Here, the size and position of the container mouth portion 11 are not particularly limited and can be appropriately changed.

As shown in FIGS. 1 and 2, the lid portion 20 is formed with a female screw portion 21 that can be screwed into the male screw 13. By screwing through the female screw portion 21 and the male screw portion 13, the lid portion 20 and the carrying can container portion 1 can be connected in a detachable state.

Further, as shown in the number 22 of FIG. 2, the safety valve 22 for reducing the internal pressure (internal pressure) of the carrying can container portion 10 is provided. The safety valve 22 is provided with at least a valve body 22b, a coil spring 22a, and an excess pressure outflow hole 22c as described later, and further includes a shaft portion and a stopper portion as shown in No. 22d of FIG. May be good.

As shown in FIG. 2A, the valve body is pushed down (inside the carrying can container) by the urging force (repulsive force) F by the coil spring 22a. On the other hand, the volatile fuel existing in the fuel storage portion 12 evaporates and vaporizes to generate an internal pressure. As shown in the number P, the internal pressure is applied to the upper side of the valve body 22b (outside the carrying can container portion). ) Is a force that pushes up (in the direction opposite to the force F).

In FIG. 2A, the urging force (repulsive force) F of the coil spring 22a is larger than the internal pressure P (F> P), so that the valve body 22b is in a state of closing the excess pressure outflow hole 22c. ing. Therefore, the evaporated / vaporized fuel does not flow out to the outside of the fuel carrying can.

On the other hand, in FIG. 2B, the internal pressure P is increased by the evaporated / vaporized fuel, and the internal pressure P is larger than the urging force (repulsive force) F of the coil spring 22a (P> F). In this case, the internal pressure P moves the valve body 22b in the direction opposite to the direction of the urging force (repulsive force) F, and the excess pressure outflow hole 22c that has been closed is opened (exposed).

Therefore, the evaporated / vaporized fuel (that is, excessive pressure) can flow out to the outside of the fuel carrying can to reduce the internal pressure P.

As described above, due to the existence of the safety valve 22, the fuel carrying can according to the present invention is highly safe because even if the internal pressure rises due to the volatilization of the volatile fuel inside the carrying can, the excessive pressure can be released to the outside. Can demonstrate sex.

According to the present invention, even if the internal pressure rises due to the volatilization of the volatile fuel inside the carrying can, the excessive pressure can be released to the outside, and even if the operator neglects the degassing work, it is highly safe. It is possible to provide a fuel carrying can that can exhibit its properties.
