Fuel filler cap with air intake for fuel container

Abstract

We provide fuel filler caps with air intake holes for fuel poly tanks. [Solution] This fuel inlet cap 1, which is integrated with an air intake hole, is used when refueling a kerosene stove directly using a nozzle while holding a kerosene poly tank 2. It is replaceable with the conventional fuel inlet cap of the kerosene poly tank, and by opening and closing the air intake hole lid of the fuel inlet cap of this invention with a single touch, the inside of the kerosene poly tank becomes at normal pressure, preventing negative pressure from forming inside the poly tank during refueling, and allowing for smooth refueling. Conventionally, when refueling from a kerosene poly tank using a nozzle, negative pressure is formed inside the poly tank, which is a problem as it hinders refueling.

Description

Technical Field

[0001] The fueling poly-tank fueling port cap with an intake hole of the present invention (hereinafter referred to as "the fueling port cap with an intake hole") relates to a fueling port cap for preventing negative pressure inside the poly-tank when fueling a stove tank or the like using a nozzle with a petroleum poly-tank.

Background Art

[0002] When fueling a stove or the like with a petroleum poly-tank, the tip of the nozzle of the poly-tank is inserted into the petroleum stove, the poly-tank is held, and the poly-tank is tilted for fueling. At this time, the inside of the poly-tank becomes negative pressure, fueling is hindered, and it is necessary to loosen the fueling port cap and intake air. In order to improve this, an intake hole is provided in the fueling port cap to make the inside of the poly-tank at normal pressure and smooth the fueling operation.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When holding a petroleum poly-tank and directly fueling a petroleum stove, the tank is tilted for fueling. When fueling, the inside of the poly-tank becomes negative pressure, fueling is hindered, and it is necessary to loosen the fueling port cap and intake air, and the countermeasure against negative pressure has been a problem.

Means for Solving the Problems

[0005] Therefore, the cap with an air intake hole of this invention prevents negative pressure from building up inside the poly tank when refueling while holding the poly tank. By opening the air intake hole cover with a single touch, air is drawn in through the air intake hole, bringing the inside of the poly tank to normal pressure and allowing for smooth refueling. [Effects of the Invention]

[0006] It has the following effects: (1) The fuel filler cap with an air intake hole allows for air intake during refueling, bringing the inside of the poly tank to normal pressure and enabling smooth refueling. (2) It is easy to install and operate, and anyone can do it. [Brief explanation of the drawing]

[0007] [Figure 1] This diagram shows an example of the fuel inlet cap with an air intake hole of the present invention, mounted on a poly tank. [Figure 2] These are an assembly drawing and a cross-sectional view showing an embodiment of the fuel filler cap with an air intake hole of the present invention. [Figure 3] These are a plan view and a cross-sectional view showing an embodiment of the male threaded intake hole component of the present invention. [Figure 4] These are a plan view and a cross-sectional view showing an embodiment of the intake hole cover component with female threads of the present invention. [Figure 5] These are a plan view and a cross-sectional view showing an embodiment of the fuel filler cap part with oversized holes of the present invention. [Modes for carrying out the invention]

[0008] The fuel filler cap with an air intake hole of this invention is attached to a plastic tank, and when refueling, the one-touch opening and closing air intake hole lid of the fuel filler cap with an air intake hole is opened to restore normal pressure inside the plastic tank, preventing negative pressure from forming inside the tank and making the refueling process smoother. [Examples]

[0009] An embodiment will be described below with reference to the attached drawings. Figure 1 is a diagram showing an embodiment of the fuel inlet cap with an air intake hole of the present invention mounted on a poly tank. It shows the fuel inlet cap with an air intake hole 1 attached to a poly tank 2 with a nozzle.

[0010] Figure 2 is an assembly diagram and cross-sectional view showing an embodiment of the fuel filler cap with an air intake hole according to the present invention. The fuel filler cap with an air intake hole consists of an air intake hole 1a with a male screw, an air intake hole cover 1b with a female screw, and a fuel filler cap 1c. 1a is inserted from below the clearance hole in the fuel filler cap 1c, and an oil-proof seal 1e is placed on the surface of the fuel filler cap 1c, which are then tightened and secured using the male and female screws of 1a and 1b. When in use, the one-touch opening / closing cover of 1b is opened with a finger to allow air intake. When not in use, the cover of 1b is closed to prevent the intrusion of rainwater, etc.

[0011] Figure 3 shows a plan view and a cross-sectional view illustrating an embodiment of the male-threaded intake hole component of the present invention. The male-threaded intake hole 1a is inserted from below into a clearance hole of approximately 19 mm in the center of the fuel filler cap 1c, and the male-threaded portion is installed protruding from the upper surface of the fuel filler cap 1c.

[0012] Figure 4 shows a plan view and a cross-sectional view illustrating an embodiment of the female-threaded intake hole cover component of the present invention. The female-threaded intake hole cover 1b has a one-touch opening and closing cover on its upper part, which can be easily opened and closed with a finger.

[0013] Figure 5 shows a plan view and a cross-sectional view illustrating an embodiment of the fuel filler cap component with an oversized hole according to the present invention. The oversized air intake cap 1c has an oversized hole of approximately 19 mm in the center of the fuel filler cap. In addition, a round, flat packing 1d (made of rubber) is attached to the upper inside of 1c to prevent leakage. [Industrial applicability]

[0014] This technology allows for easy and safe refueling of equipment at construction sites and other locations, potentially leading to widespread adoption beyond ordinary households. [Explanation of symbols]
