Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reliably filters various liquids such as various liquid filtering means, for example, soup stock filtering means used during cooking, various soup filtering means, and used oil filtering means. The present invention relates to the provision of a strainer used as a means.

[0002]

2. Description of the Related Art When squeezing out the soup stock or squeezing out the soup stock during cooking, etc., each time, a strainer prepared separately is used to strain the soup stock or the soup stock. I was doing.

Further, even in oils used for frying treatment such as tempura, since this oil is contaminated by fried foods, the oil used is strained at any time.

[0004] As the strainer used for such straining treatment, for example, there is a strainer made of a mesh cloth having a dense mesh or a wire mesh.

As the strainer used for such straining treatment, for example, a strainer bag made of strainer cloth is prepared, and the opening edge of this strainer bag is sewn in a folded state to form a bead shape. There is a guide bag portion of which a metal ring is inserted into the guide bag portion, and a handle as a considerable gripping means is provided on the ring.

[0006]

However, in the strainer constituted by such a mesh material having a dense mesh or a metal mesh, the strained object such as juice is
Alternatively, there is a difficulty that it is not possible to bring the squeezing treatment required for each to the sap or the like corresponding to the characteristics of the sap mixture to be removed from the straining object, and the straining treatment, in particular, There was a problem that clogging was generated in the screen portion.

From this point of view, even when the strainer made of the mesh material or the wire mesh is used, it is necessary to remove the foreign substances clogging the mesh each time the filter is used. However, there is a problem that it takes a lot of time and effort for the removal process. Also, with repeated use of such strainer, the juice to be strained may be damaged by the deposits on the strainer net, and in particular, the produced broth or the like causes stains or an offensive odor. There was an inconvenience.

Further, in the strainer made of such a mesh material or a wire mesh, although it is relatively expensive, it is consumed by a relatively small number of uses due to clogging or the like. However, it was difficult to use.

Further, in the strainer equipped with the strainer bag constructed by using various strainer cloths, the foreign substances mixed in the squeezed juice, oil, etc. to be strained can be reliably and evenly captured. However, although it has the feature that it can be removed, it has the disadvantage of causing clogging caused by the straining process more than the strainer equipped with the above-mentioned mesh, and it is difficult to lose the function as the strainer by a relatively small number of times of use. It was

Further, according to this method, it is more difficult to remove the deposits on the strainer cloth, and it takes a lot of time to remove the deposits, and the deposits are strained during the squeezing treatment of other liquid juices. However, it has been difficult to dissolve the liquid soup into the soup stock and spoil the properties peculiar to the liquid soup, such as the transparency and flavor.

Further, even a straining tool using such a straining cloth is relatively expensive and, in addition, clogging occurs due to a relatively small number of times of use, which is difficult to use.

From this point of view, for example, a commercially available filter paper rolled into a roll is prepared, and each time the liquid juice is strained, the new filter paper is used to filter the various liquid juices. It is possible to process.

However, when squeezing soup or the like using such a filter paper, it is necessary to attach this filter paper to the opening of the receiving container for each soup stock and hold it, and there are many difficulties in holding and supporting the filter paper. there were.

For example, in order to surely hold and support the strainer paper in the opening of the receiving container or the like, in general, the filter paper is usually not supported in the opening of the receiving container or the like in addition to the person who pours the soup. It requires a person to hold and support it, and in the absence of such manpower, inconvenience such as spilling of sap is likely to occur, and as a result, it is difficult to mix untreated sap, etc., or overflow of sap. was there.

Further, in a mode in which such a filter paper is held and supported by an opening of a receiving container or the like by hand, when a soup or the like is thrown into the filter paper surface, the filter paper surface that is deformed flexibly is deformed. Since the lower end position cannot be specified, it is difficult to conveniently pour the filtered liquid flowing out from the hanging end of the filtered paper into the opening of the receiving container or the like.

The present invention effectively eliminates the inconvenience in the conventional strainer, and uses a strainer sheet such as strainer paper provided at a reasonable price to perform a reliable straining treatment for liquid juice and the like. At the same time, it is an object of the present invention to provide a straining tool which does not require the trouble of removing deposits as clogging and which does not cause unexpected color or odor to the liquid juice or the like to be filtered out.
