Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disposable oil strainer for straining oil used in cooking such as fried foods.

[Conventional technology]

Since the oil used for cooking such as deep-frying is used several times, the used oil is filtered to remove flour, tenkasa, etc., and then stored in a storage container called an oil can. In this case, oil filtration is carried out by placing a circular or rectangular flat oil strainer made of non-woven fabric, paper, pulp, rayon, etc. on a flat wire mesh or perforated plate provided on the top of the oil can, or by placing a metal It was common practice to place an oil strainer made of the same raw material as above and bent into an inverted truncated cone shape in a wooden funnel-shaped auxiliary tool, and pour oil into the strainer.

[The problem that the idea attempts to solve]

However, when placing a flat oil strainer on a flat wire mesh or perforated plate, the distance between the wire mesh or perforated plate and the top edge of the oil can must be large enough to store a sufficient amount of oil. However, in order to lower the viscosity and increase the filtration rate, the oil must be filtered while it is still hot, which is dangerous. Furthermore, if the above-mentioned interval is increased, the oil can becomes larger.

On the other hand, when using an auxiliary tool, the oil strainer can be thrown away after filtration, but auxiliary tools that are reused tend to become unhygienic if they are not cleaned each time because the remaining oil becomes sticky and collects dust. However, it is uneconomical to make assistive devices disposable.

Therefore, the present invention is able to store a sufficient amount of oil, making oil straining easy, does not require any auxiliary tools, is disposable, simple, hygienic, and retains its shape against heat. To provide an inexpensive disposable oil strainer with good properties and excellent filtration ability.

[Means to solve the problem]

In order to achieve the above object, the disposable oil strainer of the present invention is made of polyethylene terephthalate fibers that have a heat resistance of at least 150℃, and has a basis weight of 120 to 450 g/m ² . It is characterized by comprising a cup-shaped oil strainer body made of a non-woven fabric having shrinkability, and a flange formed on the upper edge of the oil strainer body, and a convex portion on the bottom surface of the oil strainer body. It is characterized by the formation of

[Function] A nonwoven fabric that has heat-shrinkability in biaxial directions expands and contracts evenly in the vertical and horizontal directions due to heat, so the cup-shaped oil strainer does not become distorted due to heat. Moreover, the oil strainer retains its shape well against heat, and together with the reinforcement of the flange, the oil strainer body is difficult to deform even if it contains a large amount of high-temperature oil, making it suitable for heavy oil straining work. can be done safely and has good shape retention, so oil can be filtered quickly without accelerating clogging. Furthermore, due to the cushioning properties of the non-woven fabric, the bottom surface of the oil strainer body can stably contact the wire mesh or the like on which it is placed, even if it is somewhat uneven. Furthermore, when a convex portion is formed on the bottom surface, the filtration area increases and the filtration ability is improved, and since the entire bottom surface does not touch, it is possible to avoid some irregularities such as a wire mesh, and the stability is further improved.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figure 1 shows the first embodiment of the present invention, in which a disposable oil strainer 1 is made of polyethylene terephthalate fiber that has a heat resistance of 200°C and has a low basis weight.
It is made by thermoforming a biaxially heat-shrinkable nonwoven fabric with a weight of 160 g/m ² , and has an inverted truncated cone-shaped cup-shaped oil strainer body 2 and a width of about 2 mm along its upper edge 3 for reinforcement. A flange portion 4 facing outward.

To strain oil using the disposable oil strainer 1 having such a configuration, place the disposable oil strainer 1 on a flat wire mesh or perforated plate conventionally provided at the top of an oil can, and use the Pour in the remaining oil. At this time, since the biaxially heat-shrinkable nonwoven fabric expands and contracts evenly in the vertical and horizontal directions due to heat, the cup-shaped oil strainer 1 may become distorted due to the heat. There is no, but only,
This good shape retention against heat, combined with the reinforcement by the flange portion 4 formed on the upper edge 3 of the oil strainer body 2, prevents the oil strainer body 2 from deforming due to high temperatures and increases the storage capacity of the oil strainer body 2. can be formed into a sufficient cup shape, so there is no need to pour hot oil frequently, resulting in good workability, allowing for safe straining of large amounts of oil, and good shape retention, which speeds up clogging. Oil can be filtered quickly without any problems. In addition, since this disposable oil strainer 1 is molded from the nonwoven fabric, the bottom surface 5 has excellent cushioning properties.
It can be placed stably even if the wire mesh etc. has some unevenness. Furthermore, in this embodiment, since the upper part of the oil strainer main body 2, that is, the pouring opening is in the shape of a widened inverted truncated cone, the workability of pouring oil is also excellent. Disposable oil strainer 1 after straining the oil
Just throw it away and use a new disposable oil strainer 1 the next time you strain the oil.

In this example, the basis weight of the nonwoven fabric was set to 160 g/m ² in consideration of filtration ability and strength, but the present invention is not limited to this, and may be in the range of 120 to 450 g/m ² .
If the strength is less than 120g/ ^m2 , the strength is insufficient;
