Description

[Detailed explanation of the invention] [Industrial application field] This invention is a synthetic resin mold that can be made with different depths using the same mold, has a strong bottom part, and has a good straining effect. It is related to tea infuser.

[Prior Art] Conventionally, a synthetic resin tea strainer has a structure in which a bag-like straining net connected to the flange is held in the teapot by fitting the collar into the upper opening of the teapot. The straining effect will not be effective unless the depth corresponds to the depth of the teapot, so in order to correspond to the depth of the teapot to be applied, a mold with dimensions that match it is required, which poses the problem of relatively high manufacturing costs. In order to solve the problem, the present applicant filed Utility Application No. 59-48355
An application was filed for a synthetic resin tea strainer related to No.

[Problem to be solved by the invention] However, the synthetic resin tea strainer described above is a bag-shaped strainer made by welding mesh fabric to a desired depth. It is single layered, and has the advantage that it can be compressed and used even if the strainer is long compared to the depth of the teapot, but on the other hand, the bottom part is easy to tear due to rubbing against the bottom of the teapot, and the bottom part Since the lower ends of the torso are partially welded together to form a bag-like shape, there were problems such as the appearance being not very clean.

In addition, even if the bottom part is made double, if the same mesh fabric is used twice, a finer mesh will be formed by doubling, and the mesh will pass through the upper mesh fabric. Powdered tea etc.
In some cases, it may not be possible to pass through the mesh fabric on the lower side, and it may remain in the mesh of the upper mesh fabric, causing clogging, and if the mesh fabric on the upper side is made rougher, such mesh fabric may not pass through. Even if it passes through the mesh of the fabric, it may not be able to pass through the fine mesh fabric on the lower side, and as described above, there is a problem that it remains in the mesh of the mesh fabric on the upper side, causing clogging.

[Means for Solving the Problems] This invention was provided in order to solve the above problems, create tea strainers with different depths using one type of mold, and obtain a strong bottom part. A flange 1 made of synthetic resin that is supported by the opening of a tea utensil such as a teapot or pot, a cylindrical part 2 made of synthetic resin mesh fabric welded to the flange 1, and a lower edge 2a of the cylindrical part 2. and a bottom part 3 made of double synthetic resin fabrics with different meshes welded to the bottom part 3, and a synthetic resin fabric on the upper side of the double synthetic resin fabrics constituting the bottom part 3. The mesh of the fabric is substantially the same as the mesh of the fabric constituting the cylindrical portion 2, and the mesh of the synthetic resin fabric on the lower side is formed coarser than the mesh of the synthetic resin fabric on the upper side. This is a tea infuser that is said to have been preserved in shape.

[Function, Effect] The tea infuser constructed as above has the flange 1 as a teapot,
The tea infuser part 4, which is made up of a mesh cylindrical part 2 and a bottom part 3, is supported by the opening of a tea utensil such as a pot, and is suspended inside the tea utensil. It is constructed by welding,
In particular, the bottom part 3 is double-layered, the upper part of the fabric m has approximately the same mesh as the cylindrical part 2, and the lower part of the fabric m' has a coarser mesh than the upper part of the fabric m. 3, the cylindrical shape 2 is hard to deform and has excellent shape retention, and the bottom part 3 is durable against being rubbed against the inner bottom surface of the tea utensil or pressed when cleaning the inside of the tea strainer. It has an excellent tea strainer effect and avoids clogging.

Furthermore, by making the strainer net portion 4 cylindrical, it is possible to manufacture tea strainers with different depths of the strainer portion 4 using one mold, making it possible to provide a tea strainer with low production costs. It is.

[Example] Examples of the tea strainer according to this invention will be described below with reference to the drawings. FIG. 1 shows a tea infuser. 1 is a flange made of synthetic resin, and 4 is a mesh part made of mesh fabric made of synthetic resin. The mesh fabric cut on the bias is used.

The flange part 1 is made of synthetic resin such as nylon and is injection molded into a flange shape that fits the opening of the tea utensil, and the strainer part 4 is welded 5 by heat or high frequency.
The cylindrical part 2 in the sieving part 4 is made by overlapping two square pieces of synthetic resin mesh fabric m and welding a pair of sides to each other, or by making one square piece as shown in Fig. 5. The mesh fabric is folded back from the center to make it double, and the side opposite the folded part is welded 5 to form a cylinder.After turning the mesh fabric inside out so that the welded part 5 is on the inside as shown in Figure 6, The upper end of this cylindrical part 2 is inserted into the flange part 1, fitted into a mold, and welded 5 to the inner peripheral surface of the flange part 1, so that the cylindrical part 2 is continuously provided on one side of the flange part 1. Next, on the lower edge 2a of the cylindrical part 2, a coarse mesh fabric m' is applied to the lower side, and a mesh fabric approximately the same as that of the cylindrical part 2 is applied to the upper side, but is thinner than the mesh fabric m' on the lower side. m are overlapped to form a double bottom part 3, and the part of the cylindrical part 2 that contacts the lower edge 2a of the cylindrical part 2 is welded 5 from the outside, and unnecessary parts are melted and cut to form a container-shaped sieving part. 4 are configured.

In addition, as another example of the method for forming the mesh part 4, after welding 5 the bottom part 3 made of double mesh fabric m', m to the cylindrical part 2, a cylinder of a length corresponding to the depth dimension of the tea utensil is formed. The upper end of the shaped portion 2 may be welded 5 to the flange portion 1.

Further, the cylindrical portion 2 is narrowed so that the diameter thereof gradually decreases from the side of the brim 1 to the side of the bottom 3, allowing the tea infusers to be stacked one on top of the other for convenience during transportation.

As described above, by externally welding the bottom part 3 and the cylindrical part 2, the peripheral edge of the bottom part 3 is reinforced, resulting in less damage and good shape retention, making it possible to create a tea strainer that is easy to dispose of used tea leaves. can do.
