Description

  The present invention relates to a funnel with a filter provided with a filter for removing solid matters mixed in a filtrate such as used tempura oil.

  In recent years, activities have been developed in various places to reduce carbon dioxide emissions by collecting and recycling waste that can be used as resources, thereby effectively using resources and reducing incineration waste. Yes. However, in general households, oil used for tempura, etc. is often solidified by adding solid materials, etc., and this is discarded as combustible waste, which reduces the amount of combustible waste and carbon dioxide emissions. And recovery of recyclable resources was a factor that did not progress. In particular, PET bottles are frequently used as containers for collecting used tempura oil. However, since used tempura oil contains solids such as deep-fried rice cake, it is not easy to transfer it to a plastic bottle or the like. For this reason, a funnel is used to transfer used tempura oil to a plastic bottle.

  However, in order to use used tempura oil as a resource for recycling, it is necessary to remove solid matter such as fried rice cake. Many funnels having a filtering means for removing such solids have been proposed. For example, Japanese Patent Laid-Open No. 10-225385 (Patent Document 1) proposes to filter oil by placing a filter paper in a funnel. In addition, in Utility Model Registration No. 3142212 (Patent Document 2), it is proposed that a filter for separating solids is provided in the wide mouth portion at the top of the funnel.

JP-A-10-225385 Utility Model Registration No. 3142212

The filtering means disclosed in Patent Document 1 uses a commercially available filter paper to remove solids such as deep-fried rice cake. When pouring used tempura oil into a funnel, the filter paper is particularly open. The upper part may come off, and as a result, the tempura oil flows out from between the inner surface of the funnel and the outer surface of the filter paper, so that there is a problem that some solid matter cannot be filtered. Moreover, since the filtering means shown in Patent Document 2 includes a filter in the wide mouth portion at the top of the funnel, when a large amount of tempura oil is poured, it may flow out from the upper outer periphery of the funnel. There was an unintended problem.
The problem to be solved by the present invention is to provide a funnel with a filter provided with a filter capable of efficiently removing solid matters mixed in the filtrate.

  Therefore, a funnel with a filter according to claim 1 of the present invention is a funnel in which a cylinder portion is provided at a discharge port in which a filtrate holding unit for holding a filtrate and a discharge port having a smaller diameter than the opening of the filtrate holding unit are formed at the bottom. And the said discharge port is provided with the substantially hemispherical filter part which protrudes in the said filtrate holding | maintenance part side.

  Further, the funnel with a filter according to claim 2 is the solid matter according to claim 1, wherein the substantially hemispherical filter part is formed in a mesh shape, and the filter part is a solid substance that does not pass through the filter part around the filtrate holding part side. Is provided.

  Furthermore, the funnel with a filter according to claim 3 of the present invention is attached with the prefilter formed in the shape of the opening of the filtrate holding portion according to claim 1, and the mesh of the prefilter is from the mesh of the filter portion. Is also formed large.

  Still further, the filter funnel according to claim 4 of the present invention is the filter funnel according to any one of claims 1 to 3, wherein the filter part, the filtrate holding part and the cylindrical part are integrally molded with a synthetic resin.

  According to the present invention, the funnel discharge port is provided with a substantially hemispherical filter portion that protrudes toward the filtrate holding portion, so that the solid matter such as fried rice cake mixed in the used tempura oil is filtered by the filter portion. In addition to being filtered, small solids easily collect around the substantially hemispherical filter, and the vicinity of the top of the filter is kept open, so that it can be efficiently filtered.

  Further, by providing a holding part for holding the solid matter around the substantially hemispherical filter part formed in a mesh shape, the solid matter that does not pass through the filter part is held in the holding part, so that it is more efficient. It becomes possible to filter.

  In addition, a pre-filter formed in the shape of a filter is attached to the opening of the filtrate holding part of the funnel with filter, and the mesh of this pre-filter is formed larger than the mesh of the filter part. It can be removed in advance, and more efficient filtration can be achieved.

  Furthermore, since the filter part, the filtrate holding part, and the cylinder part can be integrally molded with a synthetic resin, the funnel with a filter can be manufactured at a low cost and can be used in many general households. As a result, the reduction of combustible garbage and carbon dioxide emissions and the collection of recyclable resources are promoted, which can contribute to the improvement of the global environment.

  The funnel with a filter is provided with a cylindrical portion at a filtrate holding portion for holding a filtrate and a discharge port formed at the bottom with a discharge port having a smaller diameter than the opening of the filtrate holding portion. A filter portion is provided at the discharge port, and the filter portion is formed in a substantially hemispherical shape that protrudes toward the filtrate holding portion. Moreover, the substantially hemispherical filter part is formed in a mesh shape, and it is desirable to provide a holding part for holding a solid material that does not pass through the filter part around the filtrate holding part side of the filter part. Furthermore, when filtering a filtrate mixed with a solid material having a large volume, it is desirable to attach a pre-filter formed so as to extend beyond the opening of the filtrate holder. The prefilter mesh is desirably formed larger than the filter mesh in order to remove in advance the solid matter having a large volume. Furthermore, in the funnel with a filter, it is desirable that the filter part, the filtrate holding part and the cylindrical part are integrally molded with a synthetic resin.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show a funnel with a filter according to the present invention. In this embodiment, the funnel 1 is made of polypropylene resin. The resin used may be a synthetic resin such as polyethylene resin, silicon resin, Teflon resin, etc., and these resins are particularly resistant to vegetable oils and poured slightly hot used tempura oil. However, it is desirable to have heat resistance that does not deform, cold resistance that can be used even in cold regions, and flame retardancy.

  The funnel 1 is formed with an approximately morning glory-shaped filtrate holding portion 1a on the upper side to hold the filtrate, and a drain having a smaller diameter than the opening of the filtrate holding portion 1a is formed at the bottom center of the filtrate holding portion 1a. An outlet 1b is formed, and a cylindrical tube portion 1c is integrally provided at the discharge port 1b. In addition, a plurality of ribs 1d that fit into an injection port 7a of a plastic bottle 7 described later are integrally formed in the vicinity of the discharge port 1b and on the outer periphery of the cylindrical portion 1c. The discharge port 1b is provided with a substantially hemispherical filter portion 2 raised to the filtrate holding portion 1a side.

  As shown in FIG. 3, the substantially hemispherical filter portion 2 is formed in a mesh shape in which the through holes are square. And the filtrate holding | maintenance part 1a and the cylinder part 1c are connected by this mesh | network. Further, it is desirable that the mesh be formed to have a mesh size of about 10 to 15 in order to remove a relatively small solid mixed with used tempura oil. The mesh shape of the filter unit 2 may be triangular or circular. Furthermore, a holding unit 3 for holding a solid material that does not pass through the filter unit 2 is provided around the filtrate holding unit 1 a side of the filter unit 2.

  And the filter part 2, the filtrate holding | maintenance part 1a, and the cylinder part 1c of the funnel 1 mentioned above are integrally molded by injection molding etc. with synthetic resins, such as a polypropylene resin.

  On the other hand, the funnel 1 can be equipped with the pre-filter 4 in the filtrate holding part 1a. As shown in FIG. 2, the prefilter 4 is formed in a substantially rough shape with a flat bottom surface, and the entire bottom surface is formed in a mesh shape from the vicinity of the upper end. In order to remove a relatively large solid mixed with used tempura oil, it is desirable that the mesh be formed to have a mesh size of about 8 to 12 mesh so as to be larger than the filter portion 2. Further, a plurality of ribs 4 a that fit into the filtrate holding portion 1 a are integrally formed on the outer periphery of the upper end of the pre-filter 4. The mesh of the filter unit 2 and the pre-filter 4 is not limited to the size described above, and can be changed to an optimum size depending on the size of the solid matter to be removed. The pre-filter 4 is appropriately used depending on the size and amount of solid matter mixed in the filtrate, and may not be used when it can be filtered only by the filter part 2 of the funnel 1.

Next, a method for using the funnel with filter according to the present invention will be described.
First, when filtering a filtrate such as spent tempura oil having a relatively large solid material 5 and a large amount, the prefilter 4 is attached to the filtrate holding portion 1a of the funnel 1 as shown in FIG. At this time, since the plurality of ribs 4a are in contact with the inner surface of the filtrate holding portion 1a, a gap for allowing the filtrate to flow is formed between the outer surface of the prefilter 4 and the inner surface of the filtrate holding portion 1a.

  When a filtrate such as used tempura oil is introduced from above the prefilter 4 from this state, a relatively large solid 5 is removed by the prefilter 4 and remains on the bottom as shown in FIG. Passes through the small solids 6 that can pass through the mesh and the filtrate. Thereafter, the filtrate reaches the filter unit 2 to remove the relatively small solid matter 6, and the filtered filtrate passes through the mesh of the filter unit 2 and flows out to the cylindrical unit 1c. At this time, since the substantially hemispherical filter portion 2 is raised toward the filtrate holding portion 1 a, the small solid material 6 is pushed away by the flow of the filtrate and accumulated in the holding portion 3. The small solids 6 accumulated in the holding unit 3 may move slightly along the inner surface of the filtrate holding unit 1a depending on the flow of the filtrate, but the filter unit 2 is formed in a substantially hemispherical shape. Eventually, it returns to the holding unit 3 and is accumulated again. As a result, since the mesh at the top of the filter unit 2 is always open, it is possible to efficiently filter.

  The filtrate that has passed through the mesh of the filter part 2 and has flowed out into the cylinder part 1c is injected into a plastic bottle 7 indicated by a two-dot chain line in FIG. Thus, the internal air is pressurized as the amount of filtrate to be injected increases. As described above, since a plurality of ribs 1d are integrally formed on the outer periphery of the cylindrical portion 1c, a gap is formed between the outer periphery of the cylindrical portion 1c and the inner surface of the injection port 7a of the plastic bottle 7. Then, the air in the PET bottle 7 flows out, the injection of the filtrate is allowed, and the filtrate can be injected efficiently.

  FIG. 5 shows a second embodiment of the funnel with filter according to the present invention. The difference from the embodiment described above is that the filter unit is configured as a separate body and is detachable. In other words, the upper mesh portion of the filter portion 10 is formed in a substantially hemispherical shape, and a flat flange portion 11 having an outer diameter larger than the inner diameter of the cylindrical portion 1c of the funnel 1 is formed on the outer periphery thereof. The flange portion 11 has the same function as the holding portion 3 in the above-described embodiment. Furthermore, a leg portion 12 is integrally formed so as to protrude from below the flange portion 11. The outer diameter of the leg portion 12 is set to be slightly smaller than the inner diameter of the cylindrical portion 1c of the funnel 1, and is fitted lightly into the cylindrical portion 1c. The filter unit 10 is preferably molded using the same synthetic resin as in the above-described embodiment.

  The filter portion 10 having such a configuration is mounted as shown by a two-dot chain line in FIG. 5 by fitting the leg portion 12 to the cylindrical portion 1c. Then, as in the above-described embodiment, when a filtrate such as used tempura oil is added, the solid is removed by the filter unit 10 to be filtered. At this time, since the upper surface of the collar portion 11 formed on the outer periphery of the mesh portion on the upper side serves as a holding portion to hold the solid matter, the mesh at the top portion is always opened, and efficient filtration can be performed. This is the same as the embodiment described above.

  Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. In the above-described embodiment, the example in which the filtrate is poured into the PET bottle has been described. However, the container into which the filtrate is poured may be a metal can or a glass bottle. Moreover, you may provide the fixing means which does not remove a funnel from the container which inject | pours a filtrate.

  The present invention is applicable to a funnel for filtering a filtrate mixed with a solid matter such as used tempura oil.
