Abstract

PROBLEM TO BE SOLVED: To lubricate without any oil leakage by providing a small air distribution hole in the top of a cap of an oil jug, passing a bolt through the distribution hole, passing a packing through the bolt inside the cap, and fixing it by a nut. SOLUTION: An oil flowing pipe fitted with the upper end of a soft pipe 6 reaching the bottom of a bottle 4 is integrally formed on a cap 1 covering on the top of the oil jug bottle 4 by screwing, and the oil distribution pipe 5 is extended outward outside the cap so as to be the tip of the oil jug. A small air distribution hole 15 is provided in the top of the cap 1 of the oil jug, and a bolt 2 having the outside diameter slightly smaller than the inside diameter of the distribution hole 15 is inserted therein. After passing a packing 11 through the bolt 2, the bolt 2 is fixed by a nut 10 so that a clearance between the packing 11 and the inside face of the cap 1 is held 1 mm or less. When the cap 1 is threadedly engaged with the bottle 4, the cap 1 is threadedly engaged via a packing 13 formed of rubber having a small hole 12 formed in the intermediate part.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil jug widely used not only in industry but also in households, and does not leak oil.

[Prior Art] Jugs have been used for a long time in various countries around the world, but their shape and performance have not surprisingly advanced. The bottle that is most frequently used at present is the bottle (15) shown in FIGS.
Bolt (2), packing (11, 1)
It is of a shape not equipped with 3).

[0003] By the way, anyone who has used this type of oil jug for about half a year should be aware that, even though the oil jug is not being used, the oil naturally sprinkles from the tip of the oil jug. Is leaking to the surroundings and polluting the surroundings.

[0004] Why does oil leak from an unused jug? The reason is that when the oil in the jug is consumed and the amount of oil decreases, the space inside the bottle increases, and air flows back into the bottle from the tip of the jug and the amount increases. Then, when the night temperature decreases, the air in the bottle space contracts, and the air flows backward from the tip of the bottle by the contracted amount.

[0005] In this state, when the temperature rises during the day, the air in the bottle expands, the pressure in the bottle space increases, the air in the bottle space lowers the oil level, and the oil passes through the oil flow pipe. Spilled from the tip of the jug. This phenomenon occurs when the temperature difference is 5 ° or more.
Oil leaks are increasing.

[0006] In order to prevent oil leakage, some manufacturers produce oil jugs in which the tip of the oil jug is raised diagonally upward, but this is not so effective and measures have been taken. It is the current situation.

[0007] An object of the present invention is to provide an oil jug that does not leak oil.

Means for Solving the Problems In order to achieve the above object, a small air flow hole is provided in the upper portion of the cap of the oil jug, a bolt is passed through the flow hole, and the bolt is inserted inside the cap. After passing through the packing, fix with nuts.

Next, after passing the oil circulation pipe through the center hole of a circular packing having a small air circulation hole and the same length as the inner diameter of the cap, the packing is connected with a soft pipe so that the packing and the cap are in close contact with each other. Fix it.

[Embodiment of the Invention] An embodiment of the invention will be described with reference to the drawings based on an embodiment. An air flow hole (15) as shown in FIG. 2 is drilled at the position of the cap (1) corresponding to the position of the bolt (2) in FIG. The diameter of the hole is 3mm
The following is good. Next, from the diameter of the air circulation hole (15),
A bolt (2) having a slightly smaller diameter is passed through, and the packing (11) is passed through the bolt. Then, the bolt is fixed with a nut so as to keep the gap between the packing (11) and the inner surface of the cap (1) at 1 mm or less.

Further, a circular packing (1) having a diameter equal to the inner diameter of the cap using a rubber having good elasticity or the like is used.
3) is made, and a center hole (16) having the same diameter as the outer diameter of the oil flow pipe (5) is formed in the center of the packing.
A hole (12) having a diameter of 1 mm or less is formed at an intermediate position between the circumference of the center hole and the circumference of the packing (13).

Next, the center hole (16) of the packing (13)
Through the oil distribution pipe (5), and outside the oil distribution pipe (5), a soft pipe (1) such as polyethylene.
4), the packing (13) is pressed against the inner surface of the cap (1) with this soft pipe, and fixed.

Next, a soft pipe (6) is connected to a lower part of the oil distribution pipe (5), and then the oil pipe is attached to a bottle containing oil.

[Effects of the Invention] Since the present invention is configured as described above, the following effects can be obtained.

When the air temperature rises, the air in the bottle space expands, and the pressure in the bottle space starts to become higher than the outside air pressure, an air flow hole (15) is formed in the cap (1). After the air in the space passes through the hole (12), it passes through the gap between the packing (13) and the cap (1), and further passes through the gap between the packing (11) and the cap (1). ) To the outside of the bottle, so that there is no difference in air pressure between the space inside the bottle and the outside air. That is, since the pressure in the bottle space (7) of the jug is always the same as the outside air pressure, oil leakage does not occur in the present invention even if the temperature fluctuates.

Further, when the air temperature decreases and the air in the space (7) in the bottle shrinks, the outside air flows into the air circulation holes (1).
5) through the hole (12) into the bottle space (7) and back through the oil flow pipe (5) into the bottle space (7), so that the bottle space and outside air There is no difference in air pressure. This does not hinder the pressurization of the air in the space in the bottle in the operation of the oil jug described later.

When using a jug, pressure is applied to the body of the bottle by hand. At this time, the air pressure in the space inside the bottle increases, and the packing (13) is pushed up at that moment, and the inner surface of the cap (1) is pressed. It is crimped and the hole (12) is sealed, and at the same time the packing (13) is
And the air flow hole (15) is closed. Then, the oil (9) passes through the soft pipe and the oil distribution pipe, and flows out from the oiling tip (3).
