Description

  The present invention relates to a brush such as a food brush and a method for producing the same, and more particularly to a brush such as a brush used when applying a liquid seasoning or a polishing material on the surface of a food and a method for producing the same.

  In the process of manufacturing foods such as okonomiyaki, takoyaki, bread and cookies, liquid seasonings (for example, sauces) and polishing materials (for example, egg yolk), etc. are applied to the surface of the food. It has been broken. These coatings are performed using a safe brush for food hygiene.

  At present, there are many animal hair materials used for food brushes that are widely used. Animal hair materials are excellent in paintability, but the hair materials are likely to be broken, cut or detached during use, and some of the hair materials may adhere to the food surface. Since it is difficult to find the mixed hair material, it has a problem of mixing foreign substances into food. In the case of a hair material adhering to a conspicuous portion on the surface of the food, it is easy to find, but it has a problem that the appearance quality of the food and the appearance quality, which is a coated state, are liable to be deteriorated at the time of removal.

  Therefore, a technique using a synthetic resin (chemical fiber) hair material instead of an animal hair material has been proposed in order to solve the foreign matter mixing problem (see Patent Document 1).

  However, with this technology, the hair material is made of synthetic resin, and problems such as breakage and breakage of the hair material in use have been reduced, but the method of attaching the hair material to the brush body is almost the same as the conventional method, A suitable attachment method has a problem that, when the hair material is closely supported, the hair material made of synthetic resin is more expensive than the animal hair material.

  Although it is possible to reduce the cost by forming the synthetic resin hair material integrally with the base portion of the hair material as in the techniques described in Patent Documents 2 and 3, the placement of the hair material is made on the manufacturing method and structure. Since it is difficult to make it dense, it is not suitable as a food brush.

  The technique described in Patent Document 4 is a technique that combines both cost reduction and bristle material dense support.

  However, in the technique of Patent Document 4, since the hair material is formed by dividing the front end of the film material or sheet material in the longitudinal direction into a bristle material, there is no space between adjacent hair materials, so the liquid seasoning It is unsuitable for foods that are generally applied with high-viscosity liquids such as materials and polishing materials.

  The technique described in Patent Document 5 can be cited as a technique that combines both cost and appropriate support of dense bristle materials.

  However, in the technique of Patent Document 5, the base of the bristle material formed by separating the lashes at the tips of a plurality of film materials or sheet materials is sandwiched between the plurality of plies, and each ply is separated between the adjacent bristle materials in the thickness direction. However, the bristle material is prone to breakage and breakage during the bristle separation process, and the removal of the broken bristle material is insufficient. If there is a broken hair material or a broken hair material is cut off during use, it has the same problem as the animal hair material described above.

  In particular, in food brushes for applying polishing materials such as eggs and egg yolks, eggs have a high incidence of harmful bacteria, so it is essential to maintain hygiene by washing. In this case, there is a problem that it is difficult to clean the root portion of the bristle material group, and it tends to be unsanitary.

Japanese Patent No. 2879424 Japanese Utility Model Publication No. 39-215193 Japanese Patent Laid-Open No. 10-85044 U.S. Pat. No. 3,094,729 Japanese Patent No. 2597648

  Therefore, the problem of the present invention is that it is possible to reduce the contamination of foreign materials into food by suppressing the cutting, breaking, and removal of the hair material during production and use, and it is suitable as a food brush without deteriorating the appearance quality of food. Another object of the present invention is to provide a sanitary brush such as a food brush that is easy to disassemble, clean, and assemble, and a method for manufacturing the same.
