Description

  The present invention relates to a cigarette case, and in particular, but not limited to, a portable cigarette case for cigarette butt. This cigarette holder is stored in a pocket, for example, and is used to store the cigarette by taking out the cigarette from the pocket.

  This type of butt case includes those that open and close a lid that is hinged to the main body, and those that remove the lid so that the lower main body is removed from the upper lid, with the shape of the tea tube being extremely short and flat.

  This type of butt case is usually used as an ashtray. That is, when a cigarette is smoked, the tip of the cigarette is pressed from the opening of the main body of the cigarette holder to the bottom of the main body to crush the tip and extinguish the fire. Then, the butts are inserted into the openings. When using a butt case with high sealing performance, the butt may be inserted into the opening and the lid closed with the fire still on. In this case, usually, the fire is naturally extinguished by heat removal due to lack of oxygen or contact of the flaming tip with the metal container wall.

  By the way, although the fire of tobacco is a small lump, the inside is hot, and if it is pressed, if the bottom is made of synthetic resin, it will melt partially or the surface will be rough. Therefore, the main body is made of metal. If the main body is made of metal, the thermal conductivity (endothermic property) is high, so that it is easy to absorb the fire heat of the cigarette and heat is easily dispersed throughout the main body, thereby suppressing local overheating.

  Therefore, it is preferable to use a metal material for the portion where the fire portion of the cigarette in the cigarette holder may come into contact. However, when a metal case is used, the processing, particularly the processing to clean the surface, is expensive. Therefore, it is conceivable to insert or lining a metal inner case without surface processing into a synthetic resin case that can be manufactured inexpensively and neatly. In this case, however, the number of parts (materials) increases, and the material cost and assembly cost increase. There is concern about the rise.

Japanese Patent No. 3516266.

  The present applicant has proposed a cigarette cup with high internal fire resistance and simplified assembly (Patent Document 1). This butt case inserts an inner bottom plate of metal material into the bottom of the outer case made of synthetic resin, and protrudes outward to the side surface of the inner case which is inserted into the outer case by bending the metal plate along the inner wall side surface of the outer case An outer protrusion is formed on the inner wall side surface of the outer case, and a recess for receiving the outer protrusion of the inner case is formed, and the slide tube portion that slides into the inner case and the head tube portion that is inserted into the lid body are integrally continuous. Then, a window opening for receiving the cigarette butt is opened in the middle case of the metal material having a lower end that enters the inner case, and the middle case is pushed by a leaf spring in the direction in which the outer protrusion fits into the recess of the inner case.

  It is another object of the present invention to provide a butt case that is easy to assemble.
