Next, the structure of the container 1 will be described. This container 1 having a bottomed cylindrical shape and a spout 10 formed at a part of its upper end has a circular ring body 11 made of a metal such as stainless steel or aluminum fixed along the inner peripheral surface of the upper part thereof. The oil inlet fitting 15 is removably inserted into the spout 10. The ring body 11 has a recess 12 on the outer surface of the portion corresponding to the spout 10 and has an upper half portion fixed to the inner peripheral surface of the upper end portion of the container 1, and a lower half portion having a smaller diameter than the upper half portion. It is formed as a two-stage cylinder consisting of and, and the lower half of the cylindrical portion 13 is indicated by e in the figure on the side opposite to the spout 10 with respect to the upper half and the container 1, that is, on the side of the handle 7. It is offset by the dimensions. Further, a pair of protrusions 14 and 14 that protrude inward are provided on the inner peripheral surface of the upper half of the ring body 11 and near the recess 12.

The spout 10 whose upper end is cut off obliquely is formed by inflating a part of the upper end of the container 1 to the outside as described above. It is inserted until the lower end comes into contact with the protrusion 16 provided on the inner surface. The oil filler fitting 15 has a semicircular horizontal cross section, and the curvature in the horizontal cross section becomes larger toward the top, and when inserted into the spout 10,
It protrudes above the upper end of the spout 10 cut off as described above, and has a gap between it and the inner surface of the upper end of the spout 10.
It is what gives rise to 17.

The lid 4 that closes the upper end opening of the container 1 is composed of two main lids 40 and an oil filling lid 41 attached to the main lid 40. Knob 44 from the side opposite to the mounting part of the lubrication lid 41
The main lid 40, which is integrally formed with the ring body 11, has a notch portion 58 for positioning the lid 4 with the recess 12 of the ring body 11 on the mounting portion side of the lubrication lid 41 and an upper portion of the ring body 11. A hanging piece (42) in contact with the inner surface of the half portion, and the projection (14) engages with a recess (43) formed in the hanging piece (42);
The main lid 40 is attached to the container 1 by engaging the pair of lock buttons 45, 45 provided on the above with the ribs 74 of the handle 7.

A pair of lock buttons 45, 4 arranged in the hollow knob portion 44.
As shown in FIG. 8 and FIG. 9, the reference numeral 5 includes an engaging piece 46 projecting downward through an opening 51 formed in a bottom plate 50 that closes the lower surface opening of the knob portion 44, and both side surfaces of the knob portion 44. Convex part 47 formed on the surface of the tab 54, which is projected to the side from the window 54, and a groove that slidably engages with a rail-shaped rib 55 formed on the inner surface of the knob part 44. 49,
It has a protrusion 48 extending from one side, and a compression coil spring 51 is installed between both lock buttons 45, 45.

With the protrusion 14 of the ring body 11 engaged with the recess 43 of the hanging piece 42, if the knob portion 44 located on the handle 7 is pushed downward, the engaging piece 46 of each lock button 45 is formed on the rib 74. The main lid 40 is attached to the container 1 in such a manner that it cannot be accidentally removed so as to be locked in the through hole 75 formed. When removing the main lid 40, use the fingers that pinch the knob 44 to lock both lock buttons 45, 4
Push the convex portion 47 of 5 against the compression coil spring 51, and

Is released from the engagement with the rib 74, and the knob portion 44 side may be pulled up in this state. At this time, the engagement between the concave portion 43 formed on the hanging piece 42 and the protrusion 14 is naturally released. Further, even if oil adheres to the contact surface between the hanging piece 42 and the ring body 11 of the container 1, the lid 4 can be smoothly removed.

The same lock buttons 45, 45 can be used. Further, the bottom plate 50 has a protrusion 52 projecting from its side edge locked to the inner surface of the knob portion 44,
It is attached to the knob portion 44. Furthermore, the protrusion 48
Is a rib shown in FIG. 9 protruding from the inner surface of the knob portion 44.
With 53, the lock button 44 is prevented from twisting and rattling.

As shown in FIGS. 6 and 7, the lubrication lid 41 is a main lid 1
Spring made of stainless steel, etc., placed in the recess 55 formed in the
By locking one end of 56 to a groove provided on the lower surface of the one end of the oiling lid 41, it is rotatably attached to the main lid 40,
When the oil-filling lid 41 is tilted, the spout 10 is closed to prevent dust, dust, insects, etc. from entering, and when it is raised, the spout 10 is opened. And, the opening and closing of the spout 10 by the raising and lowering operation of the oiling lid 41 here is performed by the reversing operation of the biasing direction of the spring 56 that is bent halfway, with the middle of the tilting angle range of the oiling lid 41 as a boundary. It is biased in both directions. That is, the spring 56 holds both the state where the spout 10 is closed and the state where the spout 10 is opened. Further, the oiling lid 41 here is designed so as not to open further than the state shown in FIG. 7 by the engagement with the wall surface surrounding the recess 55. The lubrication lid 41 is attached to the main lid 40 only by the spring 56 described above, and is not provided with a separate rotating shaft or the like, so that the lubrication lid 41 can be easily molded.

Now, in the upper part of the container 1, an oil purifying section A composed of two kinds of filter bodies 2 and 3 is arranged.
Both 2 and 3 are installed in the container 1 through the case 8. The case 8 has a cylindrical shape whose diameter gradually decreases in a plurality of steps from the upper end to the lower end, and is fitted into the cylindrical portion 13 of the ring body 11 to be mounted in the container 1.

The filter body 2 is formed by molding paper into a cylindrical shape with a bottom, is equipped with a large number of vertical pleats in its peripheral portion, and is housed in the case 8. The other filter body 3 is configured as a cartridge by accommodating activated carbon in an oil purifying case 30 having a cylindrical shape made of metal such as aluminum and having holes for allowing oil to pass therethrough. 8 is attached to the case 8 by placing the flange 31 at the upper edge of the oil-purifying case 30 on the stepped portion 82 surrounding the lower end opening having a small diameter. 1
It is installed inside.

The oil-purifying section A constructed by attaching the both filter bodies 2 and 3 to the case 8 is stored in the container 1 while being supported by the ring body 11, but as described above, 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 the same. It is installed at a position closer to the handle 7.
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 apparent from FIG. The flow path that connects the two is ensured without inflating a part of the container 1 to the outside.

Now, in the oil purifier configured in this way, the lid 4
With the oil removed, the used oil is poured into the tempura and filtered in the oil purifying section A. At this time,
The oil is first filtered by a filter body 2 which is a paper filter to remove fine impurities such as frying and shavings.
While passing through, the coloring components and odors are adsorbed and removed. Since the filter body 2 is provided with a large number of pleats as described above to increase the surface area, a large amount of oil can be poured at once and the filtration time can be shortened.

The oil that has passed through the filter bodies 2 and 3 in this way is stored in the oil storage portion B which is the lower portion in the container 1. The above series of oil purification is possible because even if the lid 4 is closed immediately after the oil is introduced, the air is communicated with the outside through the spout 10 or the like.

When reusing the oil stored in the oil storage section B, it is sufficient to open only the oiling lid 41 instead of opening the entire lid 4. When the oil-filling lid 41 is opened, the oil-filling lid 41 is held in that state by the spring 56, so that the oil-filling lid 41 will not be closed even if the container 1 is tilted. When the container 1 is tilted, the oil flows out of the spout 10 through the flow path between the inner surface of the container 1 and the outer surface of the case 8. At this time, even if the container 1 is tilted greatly,
Since the main lid 40 is fixed to the container 1 as described above, the lid 4 does not come off. Of course, the oil purifying section A does not come off.

On the other hand, the oil flowing out from the spout 10 is guided out by the oil filler metal fitting 15 and flows out. The oil inlet fitting 15 is provided to prevent oil from dripping from the spout 10.
Even if oil drips on the outer surface of the oil filler fitting 15, this oil enters the space 17 between the oil filler fitting 15 and the inner surface of the spout 10, and then the lower end of the oil filler fitting 15 and the protrusion 16 on the inner surface of the spout 10 It returns to the oil storage section B from a slight gap between and. This means that the oil does not cover the outer surface of the container 1.

When replacing the filter bodies 2 and 3, the large diameter portion 80 at the upper end of the case 8 projects above the cylindrical portion 13 of the ring body 11, and the outer surface of the large diameter portion 80 of the case 8 and the ring body 11 are exchanged. Since the axial center of both of them is offset from the inner peripheral surface of the upper half part, as is clear from FIG. The upper end of the case 8 may be picked up by using and the whole case 8 may be pulled out.

[Effects of the Invention] As described above, in the present invention, the lock portion for fixing the detachable lid that closes the opening to the container is provided in the knob portion of the lid, and can be put in the container. The knob is provided where there is no risk of oil sticking, so the lock is not affected by the viscosity of the oil, and the lock can be operated and the lid can be attached / detached with a light operating force. It is a thing.
