Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a tea strainer used for a tea machine.

[0002]

2. Description of the Related Art An example of a tea machine using tea leaves is shown below.
The following are known. In this, at the pouring position facing the hot water supply port, a tea strainer that puts tea leaves is attached to the funnel and provided so that it can be driven in reverse,
Above this tea strainer, a tea leaf supply unit capable of supplying a fixed amount of tea leaves is provided, and tea is poured out by discharging a fixed amount of hot water from a hot water supply port toward the tea strainer containing the tea leaves. When the tea strainer is inverted a predetermined number of times, the tea husk is inverted and discarded in the tea disposal container provided on the side, fresh tea leaves are put in the tea strainer, and the tea pouring is resumed by returning to the original position. It has become so.

[0003] As a conventional tea strainer used in this type of tea dispenser, the one shown in Fig. 11 is known. In this tea strainer a, a substantially hemispherical tea strainer b is formed by a metal mesh made of stainless steel or the like, and a metal plate such as a stainless steel plate is sandwiched around the opening rim of the tea strainer b to be caulked. A flange c is formed. The flange c functions as a reinforcing material for maintaining the shape of the tea strainer a and as a mounting member when mounted on the funnel.

[0004]

However, in the tea machine,
As described above, the tea strainer is inverted so that the tea husk is discarded. However, in the conventional tea strainer a, when the tea husk is discarded, the inner edge of the metal plate forming the flange c is removed. There is a possibility that the tea husk is caught on the edge d and remains. In the case of a tea dispenser, the washing of the tea strainer a is performed only once a day at most, so that the residue of the tea husk remains in the tea strainer a for a long time, which is not good for hygiene. There was a problem. On the other hand, if the flange c is simply made smaller, the reinforcing function becomes insufficient, so that an effective solution has not yet been found. The present invention has been completed on the basis of the above circumstances, and an object of the present invention is to provide a tea strainer capable of keeping the strength of the tea husks from being caught while maintaining sufficient strength. Still another object is to prevent the periphery of the opening of the tea strainer from coming off the flange.

[0005]

Means for Solving the Problems According to the invention of claim 1, tea is poured out by discharging hot water from a hot water supply port toward a tea strainer containing tea leaves, and the tea husk is discarded by inverting the tea strainer. The tea strainer used in the tea machine as described above,
In the case where a metal plate is formed on the periphery of the opening of a tea strainer net having a container shape with an open upper surface and a flange is formed, the metal plate forming the flange is sandwiched with the inner side shorter than the outer side. There is a characteristic in that the configuration is as follows.
According to a second aspect of the present invention, in the first aspect of the present invention, an opening periphery of the tea strainer is formed by bending outward, and an inner edge of the metal plate constituting the flange is formed by an opening of the tea strainer. The feature is that it is located outside the bent portion at the periphery.

Further, according to a third aspect of the present invention, tea is discharged by discharging hot water from a hot water supply port toward a tea strainer containing tea leaves, and the tea leaves are discarded by inverting the tea strainer. The tea strainer used in the machine, wherein a flange is formed around a metal plate on an opening periphery of a container-shaped tea strainer having an open upper surface, wherein an opening periphery of the tea strainer has a rounded corner. While being bent at a substantially right angle toward the outside with the attached, the inner edge of the metal plate constituting the flange is outside the extended portion of the inner surface of the main body portion of the tea strainer, and It is characterized in that it is located at a position that covers the rounded corner of the opening periphery.

[0007]

<Operation and effect of the invention><Invention of claim 1> Since the inner edge of the metal plate forming the flange is retracted toward the opening peripheral side of the tea strainer net, the inversion operation of the tea strainer is performed. When the tea husk is discarded, it is suppressed that the tea husk is caught on the inner edge of the metal plate and remains. On the other hand, since the outside of the metal plate is elongated, a predetermined reinforcing force can be secured. That is, it is possible to obtain a tea strainer which can maintain the strength sufficiently and eliminate the sticking of the tea husk.

<Invention of Claim 2> Since the inner edge of the metal plate constituting the flange is located further outside than the bent portion of the periphery of the opening of the tea filter net, the portion caught by the tea husk is more reliable. Can be more reliably prevented from leaving tea leaves.

<Invention of claim 3> Since the inner edge of the metal plate constituting the flange is positioned so as to cover the rounded corner of the opening edge of the tea strainer, for example, When the opening side is narrowed, the inside edge of the metal plate is caught and the opening edge of the tea filter net is prevented from falling out of the flange. Moreover,
Since the inner edge of the metal plate is located outside the extended portion of the inner surface of the main body of the tea strainer, when the tea shell is discarded due to the reversing operation of the tea strainer, the tea shell is placed inside the metal plate. Is prevented from being caught on the edge.
