Description

    The present invention relates to a teapot as a tool used for pouring hot water into tea leaves and putting out its components into hot water, so-called tea, and also relates to a simple teapot using a paper cup.

    In many countries, tea is cultivated and it is customary to pour hot water into processed tea leaves and add tea. Green tea has been loved for a long time in Japan. Recently, vending machines have become popular, and green tea drinks in plastic bottles have been sold and are well-intentioned for health. However, for those who want to enjoy the original taste of green tea, boil hot water with their own hands to make tea leaves. Pour hot water and enjoy the flavor of tea while enjoying the flavor.

    There are many tea shops in Japan, and each has its own taste and aroma. In the western part of Shizuoka Prefecture, Kawane tea (registered regional group trademark) and Kakegawa tea (registered regional group trademark) are also produced. To do. This Tenryu tea is different from the aforementioned Kawane and Kakegawa, and has a refreshing flavor that mixes both the sweetness and astringency along with the aroma of the tea, and the inventor is also the one who wants to enjoy the aroma and flavor. is there.

    When pouring tea, the pouring spout, opening and its lid, handle, etc. have been made of pottery or porcelain, etc., and so-called teapots with a round shape as a whole are often used. Add the hot water, steam a little, and pour the extracted hot water into the teacup from the spout. However, if it is only the procedure to put this tea, it is time consuming to drink tea and I do not think that it is so troublesome, but when throwing away the so-called tea leaves with a reduced taste and aroma, the curve inside the teapot Due to the uneven shape and the presence of the sprinkling nets and sprinkling holes (hereinafter referred to as tanning parts), and the tea leaves that have spread with moisture adhere to the inner wall of the teapot and the tanning part and are difficult to remove. Many people find it awkward to dispose of tea leaves and teapots. As mentioned above, there are many people who prefer tea as a health drink, but in the teapot, it is convenient to carry without having to put tea in the teapot, considering the hassle of throwing away tea leaves and washing the teapot. There seems to be a recent trend of drinking tea drinks from vending machines that do not use teapots, as PET bottles can be easily obtained.

    However, tea in the teapot is still different in flavor and aroma from vending machine tea beverages, and as a result, various methods have recently been introduced to make it easier to put tea or to make it easier to discard tea leaves. Proposals have been made. For example, a teapot lid is provided with a tea strainer net (Japanese Patent Laid-Open No. 2015-208668), a tea strainer made of a funnel filter (Japanese Patent Laid-Open No. 2015-198691), and a container covered with a tea strainer There are proposals (Japanese Patent Laid-Open No. 2008-246187), those in which teapots are integrally provided in a container opening (Japanese Patent Laid-Open No. 2001-292833), disposable teapots (Japanese Patent Laid-Open No. 2000-237021), and the like.

    However, as long as the inventor knows the above-mentioned prior art documents and the like in response to the above-mentioned request for cleaning teapots without the need to dispose of tea leaves and hassle, the structure does not sufficiently satisfy the request. . That is, the conventional technique has advantages and disadvantages in structure, and does not have a structure that sufficiently satisfies the demand for reducing the troublesomeness of discarding the tea leaves described above and not having to wash the teapot.

JP-A-2015-208668 JP2015-198691A JP 2008-246187 A JP 2001-29283 A JP 2000-237021 A

    The present invention was invented in view of the above-mentioned problems, and provides a simple teapot using a paper cup that reduces both the troublesomeness of discarding tea leaves and the trouble of cleaning teapots when discarding tea leaves until now. To do.

    The configuration of the present invention that achieves the above-described object includes a drinking cup portion C4 that is formed so as to be curved along the circumferential opening end C3 of the paper cup C and that protrudes outward from the circumferential opening end C3. A latching portion E having a stepped portion E1 to be latched, a scissors portion F formed on at least a part of the latching portion E in a direction in which the paper cup C is inclined, and a scissors portion integrated with the scissors F It is a simple teapot provided with a paper cup mounting body D having a spout G for pouring an extract from F to the outside.

  Using a readily available paper cup, form a paper cup mounting body with a paper cup locking part, tea leaf tanning part, and spout, and put hot water and tea leaves into the paper cup and pour the extraction hot water If poured from the mouth, it becomes a simple teapot. The tea leaves can be discarded or washed by removing the tea leaves by draining them, or if the paper cups are soaked due to the inner shape of the round paper cup without irregularities, the tea leaves can be discarded. Paper cups can also be discarded with tea leaves.

  Hereinafter, an embodiment of the simple teapot of the present invention will be described. First, a paper cup as the basis of the present invention will be described with reference to FIG. The paper cup C is commercially available as a paper cup as shown in FIG. 1 (a), and its structure is an inverted frustoconical container body C1, and the bottom of the container body C1 is narrowed. The bottom C2 is crimped on the side, and the upper end C3 of the container body C1 is open at the circumferential opening end C3. The diameter of the opening end C3 is larger than the diameter of the bottom C2, and the drinking cup portion C4 is formed over the entire periphery of the circumferential opening end C3 and protrudes outside the circumferential opening end C3. And since this paper cup C is made of paper, it can be easily deformed by so-called plastic deformation with the force of a finger, and the drinking cup that is rounded at the circumferential opening end C3 due to the nature of the paper fibers. Due to the structure of the part C4, it can be elastically deformed to return to its original shape with some finger force.

  The present invention focuses on the elasticity of the paper cup C and the structure of the circumferential opening end C3 and the drinking cup portion C4, and uses the paper cup C provided with the drinking cup portion C4 protruding on the outer periphery. Get a teapot.

  The paper cup C is mounted on the paper cup mounting body. FIG. 2 is an example of a paper cup mounting body. In the example of FIG. 2 (a), this paper cup mounting body D is provided with a locking portion E for mounting and locking the paper cup C, a tanning portion F for separating tea leaves and extraction hot water, and a spout for extraction hot water. G and the holding part H of the paper cup mounting body D, which are formed by integral molding of synthetic resin. Further, when the paper cup mounting body D itself is placed on a flat place such as a table, the paper cup mounting body D is placed in contact with the flat place only at a part of the line 2B-2B in FIG. As shown in the configuration diagram of FIG. 2 (b), a lower convex portion is formed at the end, and here, lower convex portions I1 and I2 are provided at the end of the locking portion E and the end of the gripping portion H. Yes.

  Here, the locking portion E has a curved shape having the same diameter as the circumferential opening end C3 of the paper cup C and a part of the cutout, and the drinking mouth of the paper cup C in a state where the paper cup C is fitted. It has a stepped portion E1 that locks the flange portion C4. A notch E2 provided in the locking portion E elastically deforms the drinking cup portion C4 of the paper cup C when the paper cup C is fitted into the stepped portion E1, thereby suppressing the hook portion F and the locking portion E (described later). ) And the stepped portion E1 to slide and insert the drinking cup portion C4.

  Further, the stepped portion E1 has a structure in which the stepped portion E1 is cut off as shown in FIG. 2C due to the integral molding of the synthetic resin as viewed from 2C shown in FIG. It has become. The cavity E3 and the above-described notch E2 become an empty portion of the synthetic resin during resin molding, and contribute to further weight reduction by reducing the filling portion of the synthetic resin.

  Further, on the side facing the heel portion F and on the upper portion of the locking portion E, as shown in FIG. 2 (d), a restraining projection E4 for restraining the drinking mouth ridge portion C4 of the paper cup C is provided. It is formed so as to protrude toward F. The restraining projection E4 is for locking the drinking cup portion C4 of the paper cup C fitted into the stepped portion E1 of the locking portion E together with the heel portion F, and particularly when putting tea in the paper cup C. At the same time, the paper cup C is prevented from slipping out or falling off when the paper cup mounting body D is tilted. In FIGS. 2 (a) and 2 (d), a restraining projection E4 is provided on a part of the locking portion E. However, in order to stabilize the locking of the drinking cup portion C4, although not shown, the locking portion You may make it provide the restraining protrusion E4 in the curved part of a certain length of the upper part of E, or several places or over the long curved part from the notch E2 to the holding part H.

  On the side that is provided on the upper portion of the locking portion E and faces the above-described restraining protrusion E4, a crease portion F is formed. This tanning part F is located at the original part of the spout G and is used for separating the extracted hot water from the tea leaves, and is used for scouring the tea leaves. The crease F is formed flat so as to close the circumferential opening end C3 of the paper cup C, and is integrally formed on the upper portion of the locking part E similarly to the restraining protrusion E4. In the example of FIG. It is formed in a comb-teeth shape. As shown in FIG. 2 (e), the comb-tooth shape is formed from the locking portion E corresponding to the spout G so as to cover a part of the circumferential opening end C3 of the paper cup C fitted into the locking portion E. The structure protrudes toward the restraining protrusion E4. This comb-teeth shape has a locking function to hold down the paper cup C, and also has a function of passing the extraction hot water and scrubbing the tea leaves when pouring tea. It is necessary for the hot water not to overflow when pouring the extracted hot water from.

Here, the experimental result regarding the comb-tooth shape of the crease F will be described.
First, a commercially available paper cup having a drinking hole opening with a radius of 36 mm is prepared, and a colored paper is pasted along the circumferential opening end, and colored water is poured to a depth of 80% of the paper cup. In this state, the paper cup was tilted, and the extent to which the discharged water colored the circumferential opening end, in other words, the extent to which the colored water would occupy the circumferential opening end, that is, the depth of the colored running water was measured. At this time, the outflow of the colored water was discharged in a laminar flow state, and to which position of the edge of the circumferential opening end C3 shown in FIG. 3 was measured in the coloring state of the circumferential opening end C3 edge. The discharge measurement result of the colored water is based on the coloring positions A and B in FIG. 3, and as a result of repeated experiments, as a maximum value, the length X between AB is 64.4 mm, and the depth Y of the colored running water is 19.9 mm. Yes, as a minimum value, the length X between AB was 61.7 mm, and the depth Y of colored running water was 17.4 mm. The average depth Y of the colored running water was about 19 mm. When tea is put in, 80% hot water will not be added much, and the extraction hot water will be blocked by the comb teeth and tea leaves, but without considering the comb teeth and tea leaves. Even from the experiment with only colored water, 19.9 (maximum value) / 36 (radius) ≈ 0.55, and the length of the longest part of the comb teeth is the radius of the mouth opening formed by the circumferential opening end C3. It turns out that more than half of the length is required at least.

  Further, a comb tooth covering a part of the mouth opening made of the circumferential opening end C3 of the commercially available paper cup C was made with a synthetic resin, and the interval between the comb teeth was measured. Since the measurement of the interval between the comb teeth is also related to the width (thickness) of the comb teeth, this width has been selected from several types (0.64 mm, 1.03 mm, 1.69 mm) based on experience, and the interval between the comb teeth is 0.84 mm. , 0,87 mm, 0.93 mm, 1.36 mm, and 1.9 mm, the quality of the water was good, the amount of residual tea leaf contained in the extract through the comb teeth was observed. As a result, when the interval between the comb teeth is 0.93 mm or less, the water of the extract is poor, and when the interval is 1.9 mm, more tea leaves are poured out with the extract, and when the interval is 1.36, the pour is poured. There was a small amount of tea leaves coming out. As a result of the experiment, as a good value, the interval between the comb teeth is close to 1.36 mm or less (though it is a value exceeding 0.93 mm, of course), the water passage is good, and there are few tea leaves poured out with the extract. It was estimated. On the other hand, as for the width of the comb teeth, in the example of the above-described three kinds of widths (0.64 mm, 1.03 mm, 1.69 mm), a comb tooth having a width of 1.69 mm is good. In the example, it is the thickest and strongest comb tooth. Even if the above-mentioned good value is adopted for the interval between the comb teeth, if the width of the comb teeth is too large exceeding 1.69 mm, the tea leaves are easily dammed and the passage of water becomes worse. In this case, it is estimated that it is necessary to extend the longest part of the above-described comb teeth to near the radius of the mouth opening. Therefore, it is considered that the width of the comb teeth is good in the vicinity of 1,69 mm.

  As a result of the above experiment, the comb teeth of the tanned portion F have a width of about 1.69 mm, a distance of about 1.36 mm, and a circumferential opening end in consideration of safety so as not to overflow the length of the longest portion. It is estimated that a dimension of 1/3 to 2/5 of the diameter of the mouth opening is good as the shape of the crease.

  As shown in FIG. 2A, the spout G of the paper cup mounting body D is narrowed in the tip direction, and the tip is a groove that is curved when viewed from the side. Extracted hot water is collected according to the shape of the spout G and poured into a tea bowl (not shown). As shown in FIGS. 2 (a) and 2 (b), the shape of the spout G is a curved groove with a tapered tip when viewed from the side, a cylindrical shape with a tapered tip, and water guides on both sides of the triangular plate shape. There are things that have been squeezed toward the front as provided, and from another point of view, the water flow may be laminar or kinked due to the length of the flow path from the base to the tip of the wrinkle F , Etc. That is, the shape of the spout G affects the flow of hot water. The influence on the flow of hot water occurs as phenomena such as the amount (thickness) of hot water flowing out, the momentum of hot water and the degree of splashing of hot water. For this reason, the length of the longest part of a comb tooth changes also with the shape of the pouring spout G. Therefore, an appropriate spout shape can be determined by the amount of hot water used frequently, the length of the comb teeth, and the diameter of the circumferential opening end C3 of the paper cup C.

  The gripping part H is for holding the paper cup mounting body D fitted with the paper cup C by holding the extraction hot water into the tea bowl (not shown) and tilting it so as to easily pour the extract into the tea bowl. The gripper H must be strong enough to lift the paper cup C containing hot water, and has a curved shape when viewed from the side of the half-cut tube to make it lighter and easier to hold. A cutout H1 is provided in the middle of the direction. This notch H1 is designed so that the paper cup mounting body D can be suspended by hanging it on a projection such as a nail (not shown) and drained. Moreover, it contributes to weight reduction by the amount of the notch H1. The curved shape or notch H1 obtained by cutting the cylinder of the gripping part H and the cavity E3 shown in FIG. 2 (c) promote the weight reduction in combination with the material of the synthetic resin, so that the paper cup C is stepped by the step part E1. Even if the paper cup C is in an empty state where no hot water or tea leaves are put into it, in other words, even if a biased force is exerted to defeat the paper cup C with the weight of the gripping portion H as shown in FIG. It is preferable that the weight can be reduced so that the paper cup C supports the paper cup mounting body D while the paper cup C is standing. This is because in the paper cup mounting body D in which the paper cup C is fitted, both hands can be used if the paper cup C does not fall down in the operation of putting tea leaves into the paper cup C and pouring hot water later. . Examples of the material of the paper cup mounting body D include polypropylene.

  As described above, the drinking cup portion C4 of the paper cup C inserted from the notch E2 is engaged with the stepped portion E1 of the paper cup mounting body D, tea leaves and hot water are put into the paper cup C, and the gripping portion H is attached. By tilting the paper cup C containing tea leaves and hot water, only the extract can be poured from the spout G into the tea bowl (not shown) while the tea leaves put in the paper cup C are being poured. After the pouring is completed, the paper cup C is removed from the paper cup mounting body D, and the paper cup C is turned upside down. It can be discarded easily, or the paper cup C can be scooped and discarded while the tea leaves are kept. Further, the attached tea leaves of the paper cup mounting body D can be easily removed by passing water through the tanned portion F.

FIG. 4 shows another example of the paper cup mounting body D.
In the example of FIG. 4, the curved locking portion E provided with the stepped portion E1 and the notch E2 without providing the holding protrusion E4 of the holding portion H and the locking portion E in the example shown in FIG. And a spout G having a comb-like shape provided on a part of the locking portion E and a spout G for guiding the flow of hot water from the heel portion F. And in the example shown to Fig.4 (a), the notch E2 is provided in the position facing the fold part F. FIG. In this structure, as shown in FIG. 4 (b), the drinking cup portion C4 of the paper cup C is fitted from the notch E2 to the stepped portion E1, and the end of the notch E2 is pressed with, for example, the thumb and the index finger. While the paper cup C containing tea leaves and hot water is tilted, the extract can be poured from the spout G. In this case, although not shown in FIG. 4B, in order to stabilize the vertical fitting between the paper cup C and the locking portion E, the locking portion E near the notch E2 is placed on the locking portion E in FIG. A restraining protrusion E4 as shown in d) may be provided. Further, if the notch E2 is narrowed (shortened) and stretched while curving the locking portion E, the circumferential opening end C3 of the paper cup C and the locking portion E are more securely locked, and the paper cup C The paper cup mounting body D is less likely to be displaced in the spout direction along the circumferential opening end C3 of the paper cup C, and the paper cup C and the locking portion E are less likely to be displaced in the horizontal direction and the fitting is stabilized. Increase. Also in this example, the example of FIG. 2 can be applied to the shape and size of the tanned portion F and the spout G.

FIG. 5 shows still another example of the paper cup mounting body D.
The structure of FIG. 5 is curved with a stepped portion E1 and a notch E2 without providing the holding projection E4 of the holding portion H and the locking portion E in the example shown in FIG. As shown in FIG. 5 (b) viewed from 5B-5B in FIG. 5 (a) and FIG. 5 (a), a paper cup C circle is formed on the upper portion of the locking portion E. A circular frame J is formed so as to cover the entire surface of the mouth opening, which is the peripheral opening end C3, and comb-shaped scissors F are provided on the entire surface of the circular frame J. A part of the circular frame J protrudes to form a spout G, and water guides G1 are provided on both sides of the spout G in the circumferential direction. Further, a hanging portion K is formed at a position facing the spout G of the circular frame J, and the hanging portion K is hung by being hooked to a projection such as a nail (not shown) so as to be drained. In this structure, as shown in FIG. 5 (c), the drinking cup portion C4 of the paper cup C is inserted from the notch E2 into the stepped portion E1, and the tea leaves and the tea leaves are pressed while pressing the circular frame J corresponding to the notch E2. By tilting the paper cup C containing hot water, the extract can be poured from the spout G. In the example shown in FIG. 5 as well, the dimensions of the tanned portion F and the shape of the spout G can be applied to those of the example of FIG. 2, and the length of the notch E2 can be applied to the example of FIG.

  The example of FIG. 6 is a modification of FIG. 5, and is a modification of the example of FIG. The locking portion E described so far including FIG. 5 has a curved shape having a notch E2 in part. However, in FIG. 6 (b) viewed from 6B-6B in FIG. 6 (a) and FIG. 6 (a), and in the enlarged example of FIG. A locking piece E5 that is partially locked with the drinking cup portion C4 of the paper cup C is formed. The locking pieces E5 are provided around the circular frame J so as to be locked at several places (three places in the figure) of the drinking cup portion C4 of the paper cup C. As shown in FIG. 6C, the locking piece E5 is formed with a claw E51 and can be locked to the drinking cup portion C4 of the paper cup C. The claw E51 of the locking piece E5 corresponds to the stepped portion E1 of the locking portion E shown in the examples of FIGS. 2, 4, and 5 and locks the paper cup C to the paper cup mounting body D. It is. The portion of the paper cup mounting body D other than the locking piece E5 of FIG. 6 corresponding to the stepped portion E1 of FIG. 5 applies the example of FIG.

  FIG. 7 is a further modification of FIG. In FIG. 7, a locking curved piece E6 having a length that closes the notch E2 of the locking portion E of FIG. 4 is rotatably provided. A stepped portion E61 is formed in the locking curved piece E6 as well as the locking portion E, and can be locked to the drinking cup portion C4 of the paper cup C. As shown in FIG. 7 (a) and FIG. 7 (c) which is a side surface of 7C-7C in FIG. 7 (a), a locking projection piece E62 is formed on one end of the locking curved piece E6. Furthermore, a fitting protrusion E63 is formed in the locking protrusion E62 in a direction perpendicular to the protrusion direction. On the other hand, the end of the locking portion E corresponding to the locking protrusion E62 of the locking curved piece E6 is a notch E2, and the locking curve from 7B-7B in FIGS. 7 (a) and 7 (a). As shown in FIG. 7 (b) except for the piece E6, a base protruding piece E7 is formed on the outside of the curve, and a receiving hole E71 is formed to fit the fitting protrusion E63 in a direction perpendicular to the protruding direction. As a result, as clearly shown in FIG. 7 (d), the fitting provided on the locking projection E62 of the locking curved piece E6 is inserted into the receiving hole E71 provided on the base protruding piece E7 of the locking portion E. When the protrusion E63 is fitted, the latching curved portion E6 rotates around the receiving hole E71, and the notch E2 of the latching portion E is inserted into the latching curved piece as shown in FIG. The paper cup C can be closed with E6, and the paper cup C can be more reliably mounted on the paper cup mounting body D. In the example of FIG. 7 as well, the shape and dimensions of the gripping portion H, the spout G, or the restraining protrusion E4 shown in FIG. 2, and the shapes and dimensions of the entire tanned portion F and the hanging portion K of FIG. it can.

8 and 9 show a further embodiment of the present invention.
The description so far has shown an example in which the creased portion F is formed flat in a comb-teeth shape so as to cover the circumferential opening end C3 of the paper cup C. This comb-teeth shape is engaged so as to cover a part of the circumferential opening end C3 of the paper cup C fitted into the engaging portion E as shown in FIG. 2 (e), and as shown in FIGS. It is formed so as to cover the entire surface of the circumferential opening end C3 of the paper cup C fitted into the stop portion E, so that the paper cup C is prevented from moving and the tea leaves are wiped out. In the example shown in FIGS. 8 and 9, the crease F is not a comb-teeth shape but a crease net or a crease hole.

  The structure shown in FIG. 8B as viewed from 8B in FIG. 8A and FIG. 8A uses a tanning net for the tanning portion F. FIG. In this example, the locking portion E has a closed circular shape with no cutout, and the stepped portion E1 of the circular locking portion E can be engaged with the drinking cup portion C4 of the paper cup C. On the other hand, the fold portion F connected to the spout G is integrally formed with the locking portion E, and is curved along the circumferential opening end C3 of the paper cup C as in the locking portion E. On the other hand, it has a shape that is planted in an upward direction that is nearly vertical, and it is planted slightly diagonally inward in the bending direction. The tanned portion F is planted and formed integrally with the spout G, and an opening is formed corresponding to the spout G, and a tanned net made of metal, for example, is attached to the opening. Further, a restraining projection E4 is formed at a position facing the fold portion F of the locking portion E, as in the structure shown in FIG. The reason why the synthetic resin in the crease F is planted slightly inward in the bending direction is that the drinking jar C4 of the paper cup C fitted into the step E1 is between the step E1 and the base of the crease F. This is because the paper cup C together with the restraining protrusion E4 is securely attached to the stepped portion E1 and thus to the paper cup attachment body D.

  In addition, the locking portion E has a shape that is integral with the fold portion F and the locking portion E, and has a shape that is lowered substantially perpendicular to the locking portion E, and is slightly inclined inward in the bending direction. It has a tongue L of a shape that is lowered. The tongue piece L has a paper cup C mounted on the paper cup mounting body D, and when the paper cup C is tilted to add tea leaves or hot water to the paper cup C and pour the extracted hot water, It is added to the container body C1 and the drinking cup portion C4 of the cup C, and in consideration of the fact that the paper cup C falls out of the locking part E depending on the weight, the tongue piece is used as a support for preventing the paper cup C from falling off. L is provided. Therefore, the length of the tongue piece L is preferably set according to the depth of the paper cup C that is frequently used. Here, the gripping portion H is configured in the same manner as in FIG. 2, and is formed integrally with the locking portion E. In this example, the notch H1 as shown in FIG. 2A is not provided, but may be formed.

  FIG. 9 is a modification of FIG. In FIG. 8, a tanning net is provided as the tanning portion F, but in the example of FIG. 9B viewed from 9B of FIG. 9A and FIG. 9B, it corresponds to the spout G of the integrally formed synthetic resin. Thus, a crease hole is provided in the planted portion of the crease portion F. Further, in this example, without providing the tongue piece L, a hanging portion K is provided by projecting to the locking portion E, and a paper cup C is placed on the locking portion E on both sides of the rising portion of the crease F. The protrusion E4 is formed so as to be easily held. In this example, lower convex portions I1, I2, and I3 are formed below the grip portion H and the locking portion E. In this example, a tongue piece L can be provided. Incidentally, the tongue piece can be provided also in the examples of FIGS. 2 and 4 to 7. Further, in the examples of FIGS. 2 and 4 to 7, the comb-shaped shape is given as the scissors portion F. Instead of the comb-tooth shape, the scissors net in FIG. 8 and the scissors holes in FIG. A structure stretched around J can also be used.

  Various paper cup mounting bodies D have been described above. By attaching the paper cup C to the paper cup mounting body D and tilting the paper cup C in which tea leaves and hot water are placed in the paper cup C, the crease F The tea leaves can be boiled and the extract can be poured from the spout G. When disposing of the tea leaves, the paper cup C can be left as it is due to the internal shape of the container body C1 of the paper cup C, or it can be washed. A simple teapot that can be easily discarded and washed can be obtained by watering the crease F of the paper cup mounting body D.

Here, an experimental result regarding the comb-tooth shape of the tanned portion F will be described.
First, a commercially available paper cup having a drinking hole opening with a radius of 36 mm is prepared, and a colored paper is pasted along the circumferential opening end, and colored water is poured to a depth of 80% of the paper cup. In this state, the paper cup was tilted, and the extent to which the discharged water colored the circumferential opening end, in other words, the extent to which the colored water would occupy the circumferential opening end, that is, the depth of the colored running water was measured. At this time, the outflow of the colored water was discharged in a laminar flow state, and to which position of the edge of the circumferential opening end C3 shown in FIG. 3 was measured in the coloring state of the circumferential opening end C3 edge. The discharge measurement result of the colored water is based on the coloring positions A and B in FIG. 3, and as a result of repeated experiments, as a maximum value, the length X between AB is 64.4 mm, and the depth Y of the colored running water is 19.9 mm. Yes, as a minimum value, the length X between AB was 61.7 mm, and the depth Y of colored running water was 17.4 mm. The average depth Y of the colored running water was about 19 mm. When tea is put in, 80% hot water will not be added much, and the extraction hot water will be blocked by the comb teeth and tea leaves, but without considering the comb teeth and tea leaves. Even from the experiment with only colored water, 19.9 (maximum value) / 36 (radius) ≈ 0.55, and the length of the longest part of the comb teeth is the radius of the mouth opening formed by the circumferential opening end C3. It turns out that more than half of the length is required at least.
