Furthermore, the partition piece 72 itself, which is formed integrally with the handle 7, does not come into contact with the outer peripheral surface of the container 1.
Since a heat insulating space 73 is provided in between, even when high temperature oil is contained in the container 1, the fingers holding the handle 7 will not get burned or feel hot.

Next, the structure of the container 1 will be explained. This container 1 has a cylindrical shape with a bottom and has a spout 10 formed in a part of its upper end.
A circular ring body 11 made of metal such as stainless steel or aluminum is fixed, and an oil filler fitting 15 is removably inserted into the spout 10. The ring body 11 has an upper half that has a recess 12 on the outer surface of the portion corresponding to the spout 10 and is fixed to the inner peripheral surface of the upper end of the container 1, and a lower half that has a smaller diameter than the upper half. The cylindrical part 13 of the lower half, which is continuous with the upper half via a step, is formed as a two-stage cylinder consisting of a side opposite to the spout 10 with respect to the upper half and the container 1; In other words, it is deviated toward the handle 7 by the dimension indicated by e in the figure. Also,
The inner peripheral surface of the upper half of the ring body 11 and the recess 12
A pair of protrusions 14, 14 protruding inward are provided in the vicinity of the protrusions 14, 14.

Spout 10 whose upper end is cut off diagonally
As mentioned above, the oil filling spout fitting 15 is formed by inflating a part of the upper end of the container 1 outward, and the lower end of the oil filler fitting 15 is attached to a protrusion 16 provided on the inner surface of the spout 10. is inserted until they touch. The oil filler fitting 15 has a semicircular horizontal cross section, and the curvature of the horizontal cross section increases toward the top. It protrudes above the cut-off upper end of the spout 10 and creates a gap 17 with the inner surface of the upper end of the spout 10.

The lid 4 that closes the upper opening of the container 1 is a main lid 40.
and an oil filling lid 41 attached to this main lid 40. The main lid 40, which has a knob 44 integrally protruding from the side opposite to the attachment part of the oil filler lid 41, has the lid 4 between the recess 12 of the ring body 11 on the side where the oil filler lid 41 is attached. and a hanging piece 42 that is in contact with the inner surface of the upper half of the ring body 11.
4 is engaged, and the pair of lock buttons 45, 45 provided on the knob 44 are engaged with the ribs 74 on the handle 7, so that the main lid 4
0 is attached to container 1.

As shown in FIGS. 8 and 9, the pair of lock buttons 45, 45 disposed inside the hollow knob part 44 are inserted downwardly through an opening 51 formed in a bottom plate 50 that closes the lower opening of the knob part 44. a convex portion 47 whose surface is provided with anti-slip unevenness that protrudes laterally from windows 54 formed on both sides of the knob portion 44;
It has a groove 49 that slidably engages with a rail-shaped rib 55 formed on the inner surface of the lock button 4, and a protrusion 48 extending from one side.
A compression coil spring 51 is installed between them.

The protrusion 1 of the ring body 11 is inserted into the recess 43 of the hanging piece 42.
4 is engaged, and if the knob portion 44 located on the handle 7 is pushed downward, the engaging piece 46 of each lock button 45 will be locked in the through hole 75 formed in the rib 74. The main lid 40 is attached to the container 1 without being accidentally removed. To remove the main lid 40, push in the convex portions 47 of both lock buttons 45, 45 against the compression coil spring 51 with fingers pinching the knob portion 44, so that both locks move while being guided by ribs 55. Engagement piece 46 of buttons 45, 45
What is necessary is to release the handle from the rib 74 and, in this state, pull up the side of the knob 44. At this time, the engagement between the recess 43 formed in the hanging piece 42 and the projection 14 is naturally released.

Incidentally, the same lock button 45, 45 can be used. In addition, the bottom plate 5
0 has a protrusion 52 protruding from the side edge of the grip portion 4.
It is attached to the knob part 44 by being locked to the inner surface of 4. Furthermore, the protruding piece 48 prevents the lock button 44 from twisting and rattling by interfacing with a rib 53 shown in FIG.

As shown in FIGS. 6 and 7, the oil filler lid 41 has one end of a spring 56 made of stainless steel or the like arranged in a recess 55 formed in the main lid 1, which is secured to the lower surface of one end of the oil filler lid 41. By doing so, it is attached to the main lid 40, and when the oil filling lid 41 is tilted down, the spout 10 is opened.
is closed to prevent dirt, dust, insects, etc. from entering, and when raised, the spout 10 is opened. The opening and closing of the spout 10 by the tilting operation of the oil filler lid 41 is performed by reversing the biasing direction of the spring 56, which is bent in the middle, at the middle of the tilting angle range of the oil filler lid 41. It is biased in both directions. In other words, both the state in which the spout 10 is closed and the state in which the spout 10 is opened are held by the spring 56. Further, the oil filling lid 41 here is prevented from opening further than the state shown in FIG. 7 by engaging with the wall surface surrounding the recess 55.

Now, an oil purification section A consisting of two types of filter bodies 2 and 3 is arranged in the upper part of the container 1. Both of these filter bodies 2 and 3 are connected to the container 1 through a case 8. is installed inside. The case 8 has a cylindrical shape whose diameter gradually decreases over multiple stages from the upper end to the lower end, and is attached to the container 1 by being fitted into the cylindrical portion 13 of the ring body 11. It will be done.

The filter body 2 is formed by molding paper into a cylindrical shape with a bottom, has a large number of vertical folds around the circumference, and is housed in the case 8. The other filter body 3 is configured as a cartridge by storing activated carbon in an oil purifying case 30 that is cylindrical and made of metal such as aluminum and has holes for passing oil through the upper and lower surfaces. The oil purifying case 30 is attached to the case 8 by placing the flange 31 on the upper edge thereof on the stepped portion 82 surrounding the small-diameter lower end opening of the oil purifier case 8 . It is installed within 1.

The oil purifying section A, which is constructed by attaching both the filter bodies 2 and 3 to the case 8, is housed in the container 1 while being supported by the ring body 11. In addition, since the cylindrical portion 13 of the ring body 11 into which the case 8 is fitted is provided near the handle 7 side opposite to the spout 10, the case 8 and the filter bodies 2 and 3 attached here are also , is also installed at a position closer to the handle 7 side. For this reason, between the outer surface of the case 8 and the inner surface of the container 1 on the spout 10 side, as is clear from FIG.
A flow path connecting the container 1 and the spout 10 can be secured without inflating a part of the container 1 outward. Also, a flow path with a sufficient cross-sectional area is formed between the spout 10 and the ring body 11 due to the presence of the recess 12 provided in the ring body 11.

Now, in the oil purifier configured in this way, with the lid 4 removed, the oil used for tempura etc. is poured into the oil purifier and filtered in the oil purifying section A. At this time, the oil is first filtered. Fine impurities such as fried crumbs and sludge are removed by the filter body 2, which is a paper filter, and then, while passing through the filter body 3, coloring components, odors, etc. are adsorbed and removed. As described above, the filter body 2 is provided with a large number of pleats to increase its surface area, so that a large amount of oil can be poured in at once, and the filtration time can be shortened.

The oil that has passed through the filter bodies 2 and 3 in this manner is stored in the oil storage section B, which is the lower part of the container 1. The above-described series of oil purifications is possible even if the lid 4 is closed immediately after the oil is added, because air is circulated to the outside through the spout 10 and the like.

When reusing the oil stored in oil storage part B,
Instead of opening the entire lid 4, it is only necessary to open the oil filler lid 41. When the oil filler lid 41 is opened, the oil filler lid 41 is held in that state by the spring 56.
Even if the container 1 is tilted, the oil filling lid 41 will not close. Then, when the container 1 is tilted, the oil passes through the flow path between the inner surface of the container 1 and the outer surface of the case 8, and flows out from the spout 10. At this time, even if the container 1 is tilted significantly, the main lid 40 is fixed to the container 1 as described above, so the lid 4 will not come off. Of course, the oil purifying section A will not come off.

On the other hand, oil flowing out from the spout 10 is guided by the oil filler fitting 15 and exits. This oil filler fitting 15 is provided to prevent oil from dripping from the filler spout 10, and even if oil drips down the outer surface of the oil filler fitting 15, this oil will be removed from the oil filler fitting 1.
5 and the inner surface of the spout 10, and then returns to the oil reservoir B through a small gap between the lower end of the oil filler fitting 15 and the protrusion 16 on the inner surface of the spout 10. This means that oil will not drip down the outer surface of the container 1.

When replacing the filter bodies 2 and 3, the large diameter part 80 at the upper end of the case 8 should be replaced with the cylindrical part 13 of the ring body 11.
In addition, the axes of the outer surface of the large diameter portion 80 of the case 8 and the inner peripheral surface of the upper half of the ring body 11 are shifted from each other. As is clear from FIG. 3, since there is a space in which a finger can be inserted, it is sufficient to use this space to grasp the upper end of the case 8 and pull out the case 8 together.

[Effects of the Invention] As described above, in the present invention, since the oil purifying section arranged at the upper part of the container is provided offset to the side opposite to the spout formed at the upper end of the container,
A flow path connecting the oil storage section at the bottom of the container and the spout can be secured between the inner surface of the container and the oil purifying section without inflating a part of the container outward. As a result, it is possible to eliminate irregularities on the outer surface of the container, thereby reducing the adhesion of oil and dirt, and even if it becomes dirty, it is easy to clean, making it good in terms of hygiene. and,
Since the container has fewer irregularities, even when the container is made of metal, there is no problem in terms of workability, and costs can be reduced.
