Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the teapot of the prior art still has the following disadvantages. (1) Since the filter unit protrudes outside the upper part of the container, the height of the teapot becomes considerably high, which is not suitable for storage. Moreover, since the filter unit is made of stainless steel, when pouring tea, the weight of the filter unit and the weight of the tea flowing into the mouth of the container are added, resulting in a problem that the head is heavy and the body part is light, and the user's hand instantly feels heavy. (2) As shown in Fig. 5, since the sealing ring and the mouth of the container are tightly sealed, when pouring tea, the water of the tea is blocked by the sealing ring, and the water of the tea cannot be completely poured, and dirt is likely to occur near the sealing ring and the mouth of the container. (3) Since the central filter hole is too large, when pouring tea, fine tea residues are also poured at the same time, which reduces the pleasure of drinking tea.

[0006] In view of the above-mentioned prior art, in order to improve many of its drawbacks, the inventor has made continuous efforts, conducted meticulous research with the attitude of pursuing better things, created test samples, repeated improvements on improvements, and finally produced the present invention that achieves the following objectives.

[0007] The first objective of the present invention is to provide the following teapot. It is that a cap and a filter part are combined into one using a connecting part and an air guiding pipe. When the cap and the filter part are fixed to the bottle mouth part of the container, since the air in the container is discharged through both ends of the air guiding pipe that communicates with the inside and outside of the container, when the hot water to be poured into the container passes through the filter part, it is a teapot in which the hot water can quickly flow into the liquid space of the container.

[0008] Another object of the present invention is to provide the following teapot. The filter part catches on and stops at a stopping part formed on the inner wall surface of the bottle mouth part of the container, and the cap coupled above the filter part is located below the bottle mouth, and a water injection part sagging downward is formed between the upper surface of the cap and the bottle mouth. Thus, it is a teapot that allows hot water to be directly and conveniently poured without having to remove the cap and the filter part every time hot water is poured.

Means for Solving the Problems

[0009] The teapot provided in the present invention includes a container, a filter part, an air guiding tube, a cap part, and a handle part.

[0010] The container has a liquid space inside, and the bottle mouth part provided at the upper end of the container communicates with the liquid space. A stopping part is formed on the inner wall surface of the bottle mouth part, and the bottle mouth part further has a bottle mouth, through which hot water (water) can flow in and out.

[0011] The filter part has filter holes through which hot water (water) can flow in and out and that can prevent the outflow of tea leaves. An air guiding tube can penetrate through an intermediate hole provided in the filter part. The filter part is arranged in the bottle mouth part from top to bottom and is blocked at the stopping part, making it impossible to move downward.

[0012] The air guiding tube has an air passage penetrating both ends, an external thread is formed on its outer periphery, and a stopping part is provided on its bottom surface. The air guiding tube is screwed and coupled through the intermediate hole of the filter part so as to be integrated with a connecting component.

[0013] The cap part includes a connecting component and a cap. The connecting component has an internal thread. A part of the connecting component is coupled to be integrated with the cap, and the internal thread of another part is screwed with the external thread of the air guiding tube so as to be integrated, and the cap and the filter part are coupled to be integrated. The cap has a circular body shape, and its outer diameter is made smaller than the inner diameter of the bottle mouth part.

[0014] The handle portion has a vertically extending portion and a gripping portion. The gripping portion is connected to the vertically extending portion, and the vertically extending portion is connected to the cap portion.

[0015] Due to the above-described structural design, the cap portion and the filter portion, which are integrally coupled using the air conduit and the connecting component, can be inserted together into the bottle mouth portion of the container. When the filter portion is stopped at the stopping portion and is in a state where it cannot be moved by an external force, it will not move downward. An annular gap is formed between the outer peripheral edge of the cap and the inner wall surface of the bottle mouth portion, and a water injection portion that dips downward is formed between the upper surface of the cap and the bottle mouth. The air conduit communicates with the liquid space of the container.

[0016] Due to the water injection portion formed between the above-described cap and the bottle mouth, when hot water is directly poured onto the cap, without the need to remove the cap, the hot water flows from the cap along the annular gap into the liquid space. Moreover, the air in the liquid space is discharged through the air conduit, and the hot water can quickly flow into the liquid space. Also, the cap and the filter portion are disposed within the bottle mouth portion and do not protrude outside the container like conventional products, so the overall height of the teapot is not too high, and the problem of the head being heavy and the body being light does not occur.

Embodiments for Carrying Out the Invention

[0018] In order for the honorable examiners to understand and agree to the features and advantages of the present invention, embodiments will be given below and an explanation will be made in combination with the drawings.

[0019] As shown in FIGS. 1 to 4, the teapot according to the first embodiment of the present invention includes a container 60, a filter portion 30, an air guiding tube 40, a cap portion 100, and a handle portion 70.

[0020] The container 60 has a liquid space 61 inside, and a bottle mouth portion 62 provided at the upper end communicates with the liquid space 61, and a stopper portion 64 is formed on the inner wall surface of the bottle mouth portion 62. In the present embodiment, the stopper portion 64 is an annular recessed groove, and hot water (water) is poured in or out from the bottle mouth 63 further provided at the upper end of the bottle mouth portion 62. A handle 65 is provided on the side surface of the container 60 to enable the user to hold it conveniently. The container 60 is made of materials such as plastic, ceramic, glass, stainless steel, and metal.

[0021] The filter unit 30 includes an annular spring 314, an upper fixing body 31, a net body 32, and a lower fixing body 33 from top to bottom. Intermediate holes 315, 323, and 332 are provided at overlapping positions in the upper fixing body 31, the net body 32, and the lower fixing body 33, respectively. A plurality of flowing water areas 311 and 333 penetrating vertically through the upper fixing body 31 and the lower fixing body 33 are provided. An annular protruding edge 312 protruding upward is formed on the outer peripheral edge of the upper fixing body 31, and small holes 313 arranged at intervals are provided in the annular protruding edge 312. The small holes 313 penetrate through the annular spring 314 to connect the annular spring 314 and the upper fixing body 31 together, so that the annular spring 314 is wound around the outer peripheral edge of the upper fixing body 31. Also, the annular spring 314 can be connected to the lower fixing body 33 as needed. The net body 32 is composed of thin stainless steel wires intersecting vertically and horizontally, and has innumerable fine filter holes 321 thereon. It deforms when force is applied, and the annular arc-shaped edge 322 curved upward provided on the outer peripheral edge is in close contact with the annular spring 314. A non-circular groove 331 protruding upward is formed around the intermediate hole 332 provided on the bottom surface of the lower fixing body 33. The groove 331 is rectangular or hexagonal. The outer diameters of the upper fixing body 31 and the lower fixing body 33 are the same, smaller than the net body 32, and the outer diameters of the upper fixing body 31 and the lower fixing body 33 are smaller than the inner diameter of the bottle mouth portion 62. The outer diameters of the annular spring 314 and the net body 32 of the filter unit 30 are smaller than the inner diameter of the bottle mouth portion 62, and moreover, smaller than or equal to the stopper portion 64 (concave annular groove) of the bottle mouth portion 62.

[0022] The air duct 40 has an air passage 41 penetrating both ends, with an external thread 43 formed on its outer periphery, and a non-circular stopper portion 42 provided at its bottom. The stopper portion 42 may be rectangular or hexagonal. The air duct 40 is passed through from bottom to top through the intermediate holes 315, 323, and 332 of each component of the filter unit 30 and is screwed and joined to the connecting component 90 to be integrated. Also, when the stopper portion 42 is fitted into the groove 331 of the lower fixing body 33, they are in a mutually pressing state. Thus, when the air duct 40 is screwed to the connecting component 90, the air duct 40 will not rotate along with the movement of other components. The air duct 40 is made of a material such as plastic or stainless steel. The air duct 40 can also be welded to the lower fixing body 33 to be integrated or integrated by integral molding.

[0023] The cap part 100 includes a connecting component 90 and a cap 80. The connecting component 90 is made of a flexible and elastic material including a stainless steel body or a plastic body. The connecting component 90 has a bottom surface part 91, side surface parts 92 with both ends of the bottom surface part 91 bent upward, and bending parts 93 formed further in the outer direction at the upper ends of the respective side surface parts 92. The included angle between each side surface part 92 and the bottom surface part 91 is an angle exceeding 90 degrees. There is a through-threaded screw 95 in the middle of the bottom surface part 91, and through holes 94 are respectively provided on each bending part 93. The two bending parts 93 are combined with the cap 80 to become one, and the threaded screw 95 is screwed with the female screw 43 of the air guiding pipe 40 to become one. By tightening the bottom surface part 91 of the connecting component 90 and the stopping part 42 of the air guiding pipe 40, the connecting component 90 and the filter part 30 are combined and fixed to become one. The cap 80 is a circular body, and the height of the upper part 81 in the middle of the cap is higher than the outer peripheral edge 82 of the cap. The part between the upper part 81 in the middle of the cap and the outer peripheral edge 82 forms an arc shape. Two convex columns 83 extending downward are formed on the inner bottom surface, and fitting grooves 831 of the same height are formed on each convex column 83. The outer diameter of the cap 80 is smaller than the inner diameter of the bottle mouth part 62. When the cap 80 is inserted into the bottle mouth part 62, an annular gap 811 is formed between the inner wall surface of the bottle mouth part 62. The cap 80 and the connecting component 90 are combined to become one. The two side surface parts 92 of the connecting component 90 protrude outward. When a force is applied to the two side surface parts 92, the two side surface parts 92 approach each other and become perpendicular to the bottom surface part 91 respectively. Further, the through holes 94 on the two bending parts 93 penetrate the corresponding convex columns 83, and when the force applied to the side surface parts 92 is released, the two side surface parts 92 are protruded outward by their elastic acting forces. Thereby, the edges of the through holes 94 of the two bending parts 93 are tightly fitted into the corresponding fitting grooves 831, and the cap 80 and the connecting component 90 are combined to become one. Therefore, the cap 80, the connecting component 90, the air guiding pipe 40, and the filter part 30 are also combined to become one. There is a certain distance between the cap 80 and the filter part 30 due to the height of the two side surface parts 92. The cap 80 is made of materials such as plastic, ceramic, glass, and stainless steel.

[0024] The handle portion 70 includes a vertically extending portion 71 and a handle part 72. In this embodiment, the vertically extending portion 71 is integrally connected onto the bending portion 93 of the connecting component 90. As shown in FIG. 5, the handle portion 70 can also be connected to the outer peripheral edge 82 of the cap with the vertically extending portion 71. When the cap 80 is placed on the bottle mouth portion 62, the vertically extending portion 71 is inside the bottle mouth portion 62, and the handle part 72 contacts the edge of the bottle mouth 63 and presses downward from top to bottom and extends in the outer direction. The handle portion 70 is made of a material such as plastic or stainless steel.

[0025] The above has described each component of the teapot 200 provided by the embodiment of the present invention and its assembly method. Next, the features during use will be described.

[0026] As shown in FIGS. 2 to 4, first put the tea leaves into the container 60. The user further holds the handle part 72 of the handle portion 70 by hand and arranges the filter portion 30 and the cap portion 100 into the bottle mouth portion 62 of the container 60. Since the upper fixing body 31 and the lower fixing body 33 are smaller than the inner diameter of the bottle mouth portion 62, they can be used smoothly. Also, since the annular spring 314 and the net body 32 are larger than the inner diameter of the bottle mouth portion 62, the annular spring 314 and the net body 32 are pressed against the inner wall surface of the bottle mouth portion 62 to cause contraction and deformation, and at the same time, elastic acting forces are stored. When a force is applied and the annular spring 314 and the net body 32 of the filter portion 30 drop to the position of the stopping portion 64 (i.e., the sunken annular groove), the elastic acting forces return to their original state and are hooked and pressed into the stopping portion 64 (i.e., the sunken annular groove). In a state where no external force is received, the filter portion 30 and the cap 80 do not move downward. On the contrary, when a force is applied to the handle part 72 to lift the cap 80 and the filter portion 30 upward and the annular spring 314 and the net body 32 are pressed by the inner wall surface of the bottle mouth portion 62, they contract and deform again, so they can be taken out smoothly. As described above, the effect of simple operation can be achieved.

[0027] As shown in FIGS. 2 to 4, when the filter part 30 and the cap part 100 are arranged in the bottle mouth part 62 of the container 60, the cap 80 is at a position lower than the edge of the bottle mouth 63, and a downwardly sagging water injection part 67 is formed between the bottle mouth 63 and the upper surface of the cap 80. The air conduit 40 communicates with the liquid space 61 of the container 60. Since the water injection part 67 is formed between the cap 80 and the bottle mouth 63, when adding hot water again, there is no need to remove the cap 80. One can directly pour the hot water onto the cap 80. The hot water flows in along the arc shape of the cap 80 through the annular gap 811, and then flows into the liquid space 61 through the gap of the annular spring 314, the water flow area 311 of the upper fixing body 31, the water flow area 333 of the lower fixing body 33, and the filter holes 321 of the net body 32, thus opening the tea leaves. As described above, it realizes the convenience in use that there is no need to remove the cap 80 every time hot water is added. Moreover, the weight of the filter part 30 and the cap 80 is light, and they are in a flat shape. When arranged in the bottle mouth part 62, they do not protrude from the bottle mouth part 62, so it will not be higher than the original height of the teapot 200, and there is no problem of a heavy head and a light body part.

[0028] As shown in FIG. 4, when the filter part 30 and the cap part 100 are arranged in the bottle mouth part 62 of the container 60, the air conduit 40 communicates with the liquid space 61 of the container 60, and the air in the liquid space 61 is discharged through the air passage 41 of the air conduit 40. Thus, it will not happen that the hot water fails to flow in due to the action of surface tension or the inflow into the liquid space 61 becomes slow, and tea can be smoothly put in.

[0029] Also, as shown in FIG. 4, when the filter part 30 and the cap part 100 are arranged in the stopper part 64 (i.e., the sunken annular groove) of the bottle mouth part 62 of the container 60, the net body 32 horizontally divides the inner wall surface of the stopper part 64 (i.e., the sunken annular groove). Due to the fine filter holes of the net body 32, when pouring the brewed tea, the tea leaf residues will not pass through the net body 32. Therefore, the tea leaf residues will not enter the poured tea, and it will not spoil the pleasure of enjoying the tea.

[0030] Figure 6 shows a second embodiment of the connecting component 50 for the teapot 200 of the present invention. The connecting component 50 is a hollow tube body, which is directly formed at the center of the bottom of the cap 80. A female thread 51 is provided at the bottom of the cap 80, and a plurality of air holes 52 are provided on the outer peripheral surface of the upper part of the female thread 51. The female thread 51 is screwed onto the male thread 43 of the air guiding tube 40. The connecting component 50 and the air guiding tube 40 are connected to each other, and the bottom of the connecting component 50 and the stopper 42 of the air guiding tube 40 are in close contact with each other, so as to be combined and fixed into one with the filter part 30. Due to the plurality of air holes 52 provided at the upper part thereof, the air that has entered the air passage 41 of the air guiding tube 40 is discharged from each air hole 52. As described above, by achieving the effect of quickly allowing the hot water to flow into the liquid space 61, tea can be smoothly put in. In this embodiment, it is not necessary to provide the two convex columns 83 as shown in FIG. 4 on the inner bottom surface of the cap 80.

[0031] Figure 7 shows a third embodiment of the connecting component 50 and the cap 80 for the teapot of the present invention shown in FIG. 6 above. The difference from FIG. 6 is that the ventilation hole 84 provided at the hollow tube portion of the cap 80 corresponding to the connecting component 50 communicates with the inside of the connecting component 50, and no air hole is provided on the outer peripheral surface of the upper part of the connecting component 50. Due to the ventilation hole 84 provided in the cap 80, the air that has entered the air passage 41 of the air guiding tube 40 is discharged from the ventilation hole 84 of the cap 80. Similarly, the effect of quickly allowing the hot water to flow into the liquid space 61 is achieved.

[0032] Figure 8 shows another embodiment regarding the handle portion 70 of the present invention. The handle portion 70 also includes a vertically extending portion 73 and a handle portion 74. The vertically extending portion 73 is a column body, which is coupled and fixed to the outer upper surface of the cap 80. The handle portion 74 is coupled on the vertically extending portion 73 to form a spherical body. This provides another convenient way to take out the cap portion 100 and the filter portion 30.

[0033] FIG. 9 shows another embodiment of the container of the present invention. The difference from the previous embodiment is that the bottle mouth portion 62 has a shape that gradually contracts downward from 63 positions of the bottle mouth, and the stopper portion 64 is provided on the inner wall surface with a contracted inner diameter. When the filter portion 30 and the cap portion 100 are arranged in the bottle mouth portion 62, the filter portion 30 is stopped at the stopper portion 64 (i.e., the inner wall surface with a contracted inner diameter), and cannot move downward. The handle portion 72 of the handle portion 70 on the cap 80 is just supported and pressed against the edge of the bottle mouth 63. Thereby, the same effect as that of the above-described embodiment is achieved.

[0034] The foregoing is only used for the description of the embodiments provided by the present invention, and in no way limits the scope of the embodiments of the present invention. All modifications and alterations made by related technicians in the technical field based on the content of the present invention shall fall within the scope of the claims of the present invention.
