Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding ceramic teapots.

Ceramic teapots, bottles, etc. (hereinafter simply referred to as teapots).

), for the connection between the main body and the base of the spout,
In particular, a technique is used to attach a metal tea strainer net for straining powdered tea, but this tea strainer must be attached closely to the inner surface of the main body to prevent powdered tea from flowing out from the outer periphery. In addition, it is necessary to be able to remove and clean it at any time.

For this reason, in the past, the main body and spout were formed separately, a mesh locking edge was machined on one side of the main body, the splice was joined, and then the edge of the tea strainer net was attached to the inside surface of the main body. A method was adopted in which locking rods were attached one by one, but not only did it require a lot of man-hours to form the locking rods, but the locking edges of the tea strainer were usually shaped like narrow grooves on the outside of the main body. There was a strong demand in the industry for an improvement, as tea particles easily adhered to the interior of the tea strainer, and it was difficult to clean the inner surface of the locking edge even after removing the tea strainer net, making it unsanitary.

In view of the above-mentioned conventional drawbacks, the present invention not only does not require a large number of man-hours to shape a teapot, but also allows the tea strainer net to be easily attached and detached, as well as to prevent tea from reaching the locking edge of the tea strainer net. It is an object of the present invention to provide a method for forming a teapot, which causes less adhesion, makes it easy to clean the inner surface of the locking edge when the tea strainer net is removed, and keeps the interior sanitary at all times.

Next, an example of forming a teapot by the molding method of the present invention will be described with reference to the drawings. In the drawing, 1 indicates a molding process in which the main body 3 and seam 4 of the teapot are integrally poured and molded (also referred to as a cast mold).

), and 2 is an upper mold that is assembled in a stacked manner on the lower mold 1, and the lower mold 1 and the upper mold 2 are arranged so that the upper half circumference of the seam 4 is fixed by the upper mold 2, The main body 3 is divided into upper and lower parts along a dividing line 6 shown in FIG.

Next, a concave annular upper groove 8 is formed in the main body 3 by the upper end of the inner peripheral surface 7 and the outer peripheral part of the lower surface of the lid holder 5, and the lower end of the inner peripheral surface γ and the bottom plate 9 A concave annular lower groove 10 is formed by the outer peripheral portion of the upper surface.

Further, a communication hole 12 is provided in one side of the main body 3 in an open shape so as to communicate with the spout 4, and a tea strainer made of a fine metal mesh is inserted into the communication hole 12 by a locking means described in detail below. A mesh 13 is fitted.

Now, a rectangular flange 11 is formed on the outer periphery of the base of the seam 4 along the outer surface of the main body 3.

The inner circumferential surfaces of the lower mold 1 and the upper mold 2 for molding are configured such that the end surface of the flange 11 on the main body side is in contact with the outer surface of the main body 3.

Therefore, at the boundary between the main body 3 and the spout 4, a stepped portion having a depth corresponding to the wall thickness of the main body 3 is formed on the inner peripheral edge of the communicating hole 12.

That is, on the inner side of the upper side of the flange 11, the width of the upper groove 8 is expanded by an amount equivalent to the thickness of the main body 3 to form a locking upper groove 14 that can easily lock the upper edge of the tea strainer net 13. On the inside of the lower side 11, the width of the lower groove 10 is expanded by an amount equivalent to the thickness of the main body 3, and a lower locking groove 15 is formed which can easily lock the lower edge of the tea strainer net 13.

Further, on the inside of the right side and the inside of the left side of the flange 11, a locking right edge 16 and a locking left edge 17, which are both stepped portions having a depth equal to the thickness of the main body 3, are formed, respectively.

Therefore, in this embodiment, the tea strainer net 13 is curved along a curved surface that is substantially the same as the outer surface of the main body 3, and the upper locking groove 14, the lower locking groove 15, the right locking edge 16, and the locking left edge are curved. 1
The upper locking groove 14, the lower locking groove 15, the locking right edge 16 and It can be fitted while maintaining elasticity via the locking left edge 17.

Now, when removing the tea strainer net 13, insert chopsticks, a spatula, etc. into the main body 3 from the tip of the spout 4, and insert the tea strainer net 1
3 can be resiliently removed by pressing against its elasticity.

Therefore, the widths of the upper locking groove 14 and the lower locking groove 15 are inevitably larger than the thickness of the tea strainer net 13 due to the above-mentioned structure, so it is not possible to easily engage and detach the tea strainer net 13. It is also easy to clean the inside.

Further, since the one-side locking right edge 16 and the locking left edge 17 are formed to face each other along the side surface of the main body 3, the main body 3 can be easily cleaned from inside.

Therefore, the inside of the teapot can always be maintained hygienically.

Furthermore, in this embodiment, each edge of the outer periphery of the tea strainer net 13 has elasticity that tightly fits along the inner surfaces of the upper locking groove 14, the lower locking groove 15, the right locking edge 16, and the left locking edge 17. Since it is held and attached, it is possible to prevent the tea strainer net 13 from moving and powdered tea from flowing out from the outer periphery of the tea strainer net 13.

In addition, as another embodiment of the present invention, a technique is also envisaged in which the end face of the seam 4 is formed into a shape that is directly connected to the outer surface of the main body 3 without providing a flange at the base of the seam 4.

However, in this case, the tea strainer net can be attached by locking the upper and lower edges of the net into the upper groove 8 and the lower groove 10, respectively, and the movement of the tea strainer net can be prevented through its elasticity.

That is, the present invention provides a method for forming a locking recess for locking the edge of a regular tea strainer net into the main body and the base of the spout in pour molding in which the body and spout of a ceramic teapot are integrally molded at the same time. By forming the spout along at least the upper and lower sides of the inner surface of the connecting part, the main body and spout of the teapot can be formed at the same time, and it does not require many man-hours to form the teapot. This makes it easy to attach and detach the tea strainer net, there is less adhesion of tea to the locking edge of the tea strainer net, and it is easy to clean the inner surface of the locking edge when the tea strainer net is removed. It can be maintained hygienically, and the effects of the present invention are extremely significant.

Note that, unlike the above-described embodiment, the mold may be divided into left and right parts along a dividing line 6A shown by a chain line in FIG.
