Abstract

PROBLEM TO BE SOLVED: To make the male blade and female blade of a mill container inexpensive, light in weight and strong against wear and to accurately manufacture them. SOLUTION: The main body of the male blade and the female blade is made of plastic and the blade surface of the blades is made of metal. Since the main body is made of plastic, it is inexpensive and light in weight. Since the blade surface is made of metal, it is resistant to wear and accurately manufactured.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mill container for pulverizing contents such as grain pepper and sesame, turning it into a powder, and discharging it out of the container.

[0002]

2. Description of the Related Art Mill containers for pulverizing the contents of granular pepper, sesame and the like, turning them into powder and discharging them out of the container are disclosed in Japanese Utility Model Laid-Open Nos. 56-69337, 62-204536 and 7-236576. Various things have been proposed, such as those disclosed in the gazette. Each of the mills attached to the mouths of these mill containers has a male blade and a female blade, and relatively rotates these blades to pulverize the contents. The male blade and the female blade in these conventional mill containers are entirely made of metal, ceramics, or hard plastic.

[0003]

The male blade and the female blade in the conventional mill container are entirely made of metal, ceramics or hard plastic. However, when the metal blade is made of metal, the cost of the blade is high. There is a problem that the weight becomes heavy. In the case of ceramics, it is not only expensive but also it is very difficult to manufacture the blades with high accuracy. In the case of a hard plastic, not only the blade is worn and the sharpness is deteriorated as it is used, but also the plastic of the worn blade is taken into a human body, and there is a possibility that the health is adversely affected.

An object of the present invention is to make male and female blades of a mill container inexpensive, lightweight, resistant to abrasion, and capable of being manufactured with high accuracy.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a mill container in which a mill having a male blade and a female blade is attached to a mouth portion, and the contents are crushed by relatively rotating the male blade and the female blade. A mill container to be discharged outside the container, wherein the main body of the male blade and the female blade is made of plastic, and the blade surfaces of these blades are made of metal.

The male blade and the female blade in the present invention are inexpensive and lightweight because the main body is made of plastic. Since the blade surface is made of metal, it is resistant to wear and can be manufactured with high accuracy.

The metal blade surface can be manufactured by pressing a thin plate or by a method such as casting. The blade body made of plastic is manufactured separately from the blade surface, and the blade surface can be attached by caulking or bonding to be integrated. Also, a male blade in which the blade main body and the blade surface are integrated by a so-called insert method in which a previously manufactured blade surface is attached to an injection molding die and molten plastic is injected into the die and the blade surface. Alternatively, a scalpel blade can be manufactured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a mill of a mill container 1 according to the embodiment. The mill container 1 includes a container body 2 and a mill 3. The container main body 2 is a glass bottle, and a mill 3 is screwed to the mouth thereof. The mill 3 has an inner cylinder 4 and an outer cylinder 5. The inner cylinder 4 is made of plastic, and a thread formed below the inner periphery is screwed to the mouth of the container body 2. Further, a knife blade 7 is fixed at the upper portion by welding, bonding or the like. The outer cylinder 5 is made of plastic, and is rotatably mounted outside the inner cylinder 4. A male blade 6 is fixed to the inner surface of the top wall of the outer cylinder 5 by welding, bonding, or the like. The top wall is formed with a discharge port 8 through which the crushed contents are discharged.

As shown in FIGS. 1 and 3, the male blade 6 has a substantially truncated cone shape, and the main body 6a is made of plastic.
The blade surface 6b on the outer peripheral surface is made of stainless steel. Blade surface 6
b is obtained by pressing a thin stainless steel plate to form a truncated cone and simultaneously forming the blade 9.

As shown in FIGS. 1 and 4, the knife blade 7 has a substantially ring shape, but has an inner peripheral surface which is tapered such that its diameter decreases as it goes downward. The main body 7a of the knife blade 7 is made of plastic, while the blade surface 7b on the inner peripheral surface is made of stainless steel. The blade surface 7b is formed by pressing a thin stainless steel plate, forming the blade into a truncated cone, and forming the blade 9 at the same time.

FIG. 5 shows the blade surface 6b of the male blade 6 and the female blade 7
3 shows a cross-sectional shape of the blade 9 formed on the blade surface 7b of FIG. The blade 9 can have various forms, for example, as shown in 9a to 9d in FIG.

The above embodiment is merely an example of the mill container of the present invention, and it goes without saying that design changes can be appropriately made to matters not described in the claims.

[0013]

The male blade and the female blade of the mill container of the present invention can be manufactured accurately at low cost, and are lightweight and have high wear resistance. In addition, since there is almost no wear of the blade, there is no fear that the components of the blade are taken into the human body and adversely affect health.
