Description

  The present invention relates to a brush suitable for cooking, etc., in which hair is not easily removed.

This type of brush is used to apply a highly viscous material such as egg yolk or syrup to foods, for example, for cooking. At that time, the resistance between the hair and the surface of the food to be applied is large. There is a problem that the hair is easily pulled out by a large tensile force acting on the hair bundle. Since the foodstuff becomes defective due to such hair residue, etc., it is strictly required that the hair is not removed particularly for a brush for cooking. Conventionally, as a brush of this type, for example, as shown in Patent Document 1, a base of a hair bundle is inserted into a hair bundle insertion tube made of a rigid material, and the base is impregnated with an adhesive in this state.・ By curing, the base is fixed in the hair bundle insertion tube, and the fitting portion formed on the proximal end side of the hair bundle insertion tube is fitted to the fitting portion formed at the tip of the handle portion. Thus, there is known one in which the hair is fixed to the tip of the handle. However, with this brush, there is a problem that the hair tends to come off particularly from the outside by applying a large load to the hair bundle as in cooking.

In addition, as another brush, for example, as shown in Patent Document 2, each hair of a portion fixed to a handle of a brush body formed by bundling hair in a predetermined shape is folded before the application portion. Things are known. However, in the case of this brush, since each hair of the portion fixed to the handle of the brush body has to be folded before the application portion, the manufacture of the brush becomes complicated and the manufacturing cost increases. Further, since an extra folded portion is required for each hair at the portion fixed to the handle of the brush body, there is a problem that the amount of hair used increases, the cost increases, and the hair material is wasted.

In addition, as another brush, for example, as shown in Patent Document 3, as a hair bundle portion, one end side of a hair bundle made of a chemical fiber such as acrylic is melted by heating to fix the hair bundle, and a molten portion There is known one provided with a plate-like support portion in which the plate is extended in a direction perpendicular to the longitudinal direction. However, melting of the hair bundle by heating requires a separate heating device, and there is a problem that skill is required to perform stable welding because the heating conditions are severe.
