Description

[Detailed description of the invention] The present invention relates to a teapot whose lid is magnetized and attached, and in particular, an inner flange provided horizontally at the upper part of the teapot and a horizontal lower surface of the periphery of the teapot lid are attached to the inside flange of the teapot. By the ring-shaped magnet plate and iron ring plate installed on the horizontal lower surface of the part and the lid,
This relates to a teapot whose lid is magnetized and attached horizontally to the teapot.

Teapots have been incorporated into daily life since ancient times in Japan.
However, when using a teapot, you simply put the tea leaves in, heat the water, and then place the lid on to pour the tea, which sometimes causes the lid to fall off or tea to spill through the gap in the lid. The situation was ripe.

Despite this inconvenience, there were many cases where mimomo was used, perhaps out of long-standing custom. Improvements were also desired.

For this reason, proposals have been made to prevent the lid from falling off when using a teapot.

For example, Public Utility Model Publication (Utility Model Publication No. 49-148285)
The scope of the utility model registration claim for the teapot (No.) is as follows: A magnet is provided at an appropriate position on the lid that opens and closes the opening of the main body of the teapot, and an iron wire that is attracted to the magnet is provided at an appropriate position in the opening of the main body of the teapot. A teapot characterized by: 〓.

The specification of this publication clearly states that the lid is suctioned so that it does not slip off.

However, the teapot seen in this example and its lid are also made of ceramic.

Generally, when manufacturing teapots from ceramics, the distortion and finish accuracy of the lid and teapot vary due to differences in shrinkage rates between the lid and teapot during the manufacturing process, temperature differences in the furnace, etc. It is common practice in this industry for the lid not to fit snugly with the opening. In other words, in the production of teapots using ceramics,
It is said to be extremely difficult, if not impossible, to manufacture a lid that fits accurately into the teapot opening.

However, the proposed publication for the above example is...
It is detailed that magnets are placed in the right places, iron wires are placed in the right places, etc., and in the illustration, the main body of the teapot and the lid are shown without any gaps, and the magnets and iron wires are placed side by side so that their side walls touch each other. ing.

In this illustration, the iron wire (or magnet) on the outer circumference side is arranged concentrically with respect to the magnet (or iron wire) on the inner circumference side, and the shapes of the magnet and iron wire can be seen in the detailed description of the configuration. ...with a ring-shaped magnet...
Even if the iron wire is not ring-shaped but several short pieces of iron wire arranged at appropriate locations, the magnet and the iron wire are arranged concentrically, and the side walls are parallel to each other and touch each other. .

Therefore, the main body and lid of the teapot shown in this example are manufactured so that they fit together accurately without any gaps.

As mentioned above, it is difficult to manufacture with high precision in this type of pottery manufacturing process, so for example, a large number of lids are prepared for one teapot body, and a lid that fits closely is selected from among them, and other types of lids are prepared. It is presumed that this would be a real inconvenience as it would become unnecessary.

Ignoring the shape of the teapot body and lid and the process of bringing them into close contact, even if a high-precision body and lid could be mass-produced, the suction means would be parallel side walls, and the illustration shows a cross-sectional view. Since it is circular, the adsorption is point or linear, and strong adsorption cannot be expected.

The present invention is proposed in view of these points, and is a magnetization attachment that is compatible even when the teapot and lid do not fit closely together, and is based on the original manufacturing process of teapots. The present invention is characterized by the fact that the means is surface-to-surface magnetization mounting.

I explained the manufacturing process of a teapot earlier, but for teapots such as this type of ceramic, if the lid is made larger than the teapot itself, the lid cannot be used, but if the lid is made slightly smaller than the teapot itself, then the lid cannot be used. Even if the lid is made due to distortions or irregularities in diameter during the manufacturing process, consideration is given to manufacturing it so that it fits the teapot.

Describing the embodiment in detail with reference to the drawings, the upper part of the teapot body 1 is provided with a horizontal inner flange 12 around the entire inner wall on which the lid 4 can be placed, and the base of this inner flange 12 An inner circumferential side wall 11 is provided above the teapot, forming a hot water supply port 2, and forming a teapot body 1.

The lid 4 placed on the teapot body 1 has an outer diameter dimension defined by the outer peripheral wall 21 of the lid 4 such that there is an appropriate gap within the inner diameter formed by the inner flange 12 and the inner peripheral side wall 11 of the teapot body 1. The lid 4 has a size that allows it to be fitted as a lid 4, and is formed by a horizontal lower surface 22 at its periphery,
A lid 4 is formed. This teapot and lid are formed by conventionally known means.

The ring-shaped magnet plate 3 has an outer peripheral end that can be fitted into the inner diameter formed by the inner flange 12 and the upper inner peripheral side wall 11 of the main end 1 of the teapot. It is adhesively fixed to the upper surface of the inner flange part 12.

Although this ring-shaped magnet plate 3 is thin, it is commonly called a rubber magnet, a rubber-filled magnet, or a rubber magnet, and is soft or semi-soft, which is different from traditional steel magnets and recent ferrite magnets. magnets are preferred.

The material of the magnet plate is not limited as long as it is a soft or semi-soft ring-shaped magnet plate 3, but this type of magnet plate cannot be expected to be extremely thin, and due to its magnetic force, it will wear out by 3 to 5 minutes. In the illustration, a wide ring-shaped magnet plate 3 protrudes inward from the inner flange 12.
However, the width is not particularly limited.
The iron ring plate 5 corresponding to the ring-shaped magnet plate 3 is adhesively fixed to the horizontal lower surface of the lid 4, and is a thin iron ring plate 5 with an appropriate width.

The adhesive used to bond the ring-shaped magnet plate 3 and the iron ring plate 5 is an adhesive made of silicone rubber, etc., and the ring-shaped magnet plate 3 has a magnetic force sufficient to hold the lid 4 when tilted. The magnetic plate has such a magnetic force that the lid can be removed while keeping the teapot body 1 stationary when only the lid 4 is lifted.

In addition, in the above detailed description, a magnetic plate is placed on the teapot body 1 side,
A magnetic iron ring plate was provided on the lid 4 side, but the teapot body 1
Providing an iron ring plate on the side and a magnet plate on the lid 4 side is simply a design change of the present invention, and should of course be taken into consideration.

Some of the silicone rubber adhesives mentioned above are toxic from a food-related point of view, but with recent improvements in adhesive manufacturing technology, non-toxic ones have been developed. Needless to say, adhesive is used.

The teapot of the present invention can be used to pour hot water into the teapot.

Since the present invention has the above-described configuration, the following effects can be expected and obtained.

Even if the main body and lid manufactured by the ceramic teapot manufacturing process have a gap in their outer diameter, the present invention can be applied by providing the ring-shaped magnet plate and the iron ring plate at predetermined locations. techniques can be used.

Even if the inner flange of a ceramic teapot is not a good horizontal surface due to its rough surface, the thickness of the adhesive such as silicone rubber can be adjusted to fix the ring plate horizontally. can do.

Since the annular magnet plate is made of a soft rubber magnet, it is suitable for packing materials and can be expected to have a synergistic effect on magnetization and attraction.

Since it is magnetized in a planar manner, it is possible to prevent the lid from coming off and also to prevent the tea from leaking.

Even if the magnetic plate has a weak magnetic force that allows you to remove the lid while keeping the teapot stationary, the folding of the magnet will result in a planar magnetization and a strong magnetic force.
Even if the lid is magnetized and the teapot is tilted to serve tea, the lid will not come off. Such a thing cannot be expected when attracting or magnetizing a point or a line.

Since an adhesive such as silicone rubber is used, even if a ceramic or metal plate has a different expansion coefficient due to a rise in heat due to hot water supply, the magnetic plate, etc. will not come off.

The magnet plate and iron ring plate have appropriate widths and are arranged in a ring-shaped upper and lower contact shape on the horizontal surface, so even if the outside diameter of the lid is quite different from the teapot body, there will be no problem in attaching the magnet. do not have.

As described above, using the teapot of the present invention, pour tea leaves into the teapot, fill it with hot water, and tilt the teapot to pour tea into the bowl. The lid does not separate from the main body.

Therefore, the present invention can be said to be highly practical.
