Description

Technical Field

[0001] The present invention relates to a teapot structure, and more particularly to a teapot that prevents the lid from falling off. Background Art

[0002] During the process of pouring tea, since the teapot needs to be tilted in the direction of pouring tea so that the tea water in the teapot can flow out, there is a certain inclination angle between the teapot body and the lid. Therefore, during the process of pouring tea, an external force is required to press the lid to prevent the lid from detaching from the teapot body. However, users often forget to press the lid, resulting in the lid falling off and breaking, and at the same time, the tea water overflows from the spout of the teapot and splashes everywhere. In addition, if the brewed tea in the teapot is in a high-temperature state, it is very easy to cause burns if the lid is pressed during the process of pouring tea.

[0003] Some existing products for preventing the lid from falling off generally have a buckle and a slot provided on the lid and the spout. When the user operates, the lid needs to be fixed by rotating the buckle with hand force to achieve the closing of the lid and the spout.

[0004] In addition, the handle of some known teapots can be movably retracted to both sides. When pouring tea, the user holds the handle to pour tea. If the connection between the handle and the teapot is loose, it will shake left and right, and the user will hold the handle and pour tea with unstable left and right shaking. Summary of the Invention

[0005] In order to overcome or at least solve the problems existing in the prior art, the present invention provides a teapot that prevents the lid from falling off, which can avoid the lid from falling off, the tea water from overflowing, and prevent burns during the process of pouring tea.

[0006] The present invention further provides a teapot that prevents the lid from falling off, and the lid can be slid into the spout by gravity and closed automatically.

[0007] The teapot that prevents the lid from falling off according to the present invention includes: a teapot body and a lid; the teapot body includes a spout, a handle, an inner wall of the teapot, and a first sliding convex block, and the first sliding convex block protrudes from one side of the inner wall of the teapot. The lid includes a lid top and a lid wall. The lid wall includes a bottom edge and a first inclined groove. The lid wall extends downward from one side of the lid top by a certain height, so that the free end of the lid wall forms the bottom edge. One side of the bottom edge obliquely opens the first inclined groove towards the lid wall. The first inclined groove forms a first open end at the free end on one side of the bottom edge, and a first bottom edge is formed on the other side of the first inclined groove relative to the first open end. The first inclined groove enables the first open end to be slidably rotated into the first sliding convex block, and the first sliding convex block can be movably clamped at the first bottom edge, whereby the lid can be detachably closed on the spout of the teapot body.

[0008] Compared with the prior art, a teapot of the present invention for preventing the kettle lid from falling off can avoid the falling off of the kettle lid, the overflow of tea water and prevent scalding during the process of pouring tea.

[0009] According to some embodiments of a teapot of the present invention for preventing the kettle lid from falling off, the number of the sliding protrusions is two or more. The corresponding inclined grooves are two or more. The combination of multiple sliding protrusions and the respectively corresponding and adapted multiple inclined grooves can provide fixation for the kettle lid and the kettle mouth in multiple directions and have a better fixation effect. The kettle body further includes a second sliding protrusion, which protrudes from the other side of the inner wall of the kettle. The kettle lid further includes a second inclined groove, which is obliquely opened from the other side of the bottom edge towards the kettle lid wall to form the second inclined groove. The free end of the second inclined groove on one side of the bottom edge forms a second opening, and the second bottom edge is formed on the other side relative to the second opening. The second sliding protrusion can be slidably and actively inserted into the second sliding protrusion from the second opening of the second inclined groove, and the second sliding protrusion can be actively clamped at the second bottom edge. At the same time, the first inclined groove can be actively clamped at the first sliding protrusion synchronously. The kettle lid has fixation in multiple directions within the kettle mouth, and the kettle lid can be more stably fixed at the kettle mouth during the process of pouring tea.

[0010] In some embodiments of a teapot of the present invention for preventing the kettle lid from falling off, the kettle lid can be slidably and actively inserted into the kettle mouth by gravity and closed. In some embodiments of the teapot for preventing the kettle lid from falling off, the teapot is made of various materials such as ceramic, metal, acrylic or glass. The kettle lid itself has a certain weight. When the user places the first opening above the first sliding protrusion and the second opening above the second sliding protrusion, and there is no support on the lower side of the kettle lid, when the user slightly loosens the fingers, the kettle lid, due to its own weight, causes the first inclined groove and the second inclined groove to be slidably and actively inserted into the first sliding protrusion from the first opening respectively by the weight of the kettle lid. The first sliding protrusion can be actively clamped at the first bottom edge, and at the same time, the second opening can be slidably and actively inserted into the second sliding protrusion, and the second sliding protrusion can be actively clamped at the second bottom edge.

[0011] Thereby, the kettle lid can be slidably and actively inserted into the kettle mouth by gravity and detachably closed on the kettle mouth of the kettle body. Compared with the conventional teapot, the teapot of the present invention for preventing the kettle lid from falling off increases the smooth effect of the combination of the kettle lid and the kettle mouth when using the teapot.

[0012] The present invention further provides a teapot. The handle can stably fix the teapot body when pouring tea and will not shake left and right, overcoming the problem of the left and right shaking when the user holds the handle of the teapot to pour tea.

[0013] Some embodiments of a teapot according to the present invention, such as the connecting part and the handle of the teapot body in the foregoing embodiments; a connecting hole structure is formed inside the connecting part, the bottom side of the connecting part is an arc-shaped groove, and the arc-shaped groove extends upward to form a polygonal hole; the free ends on both sides of the handle form a polygonal structure, the volume of the polygonal structure is less than or equal to the internal space of the arc-shaped groove, and the volume of the polygonal structure is less than or equal to the internal space of the polygonal hole. The polygonal structure can be movably assembled in the arc-shaped groove of the connecting part. When the handle lifts the teapot body, the polygonal structure can be detachably clamped in the polygonal hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the handle of the teapot can be placed and stored movably on both sides. The polygonal structures at the free ends on both sides of the handle of the teapot can be correspondingly and adaptively combined in the polygonal holes. When pouring tea, the user holds the handle and lifts the teapot upward. The polygonal structures on both sides of the teapot can be respectively detachably clamped in the polygonal holes on both sides of the teapot body, and the handle will not loosen and sway left and right. The user can hold the handle and stably lift the teapot to pour tea when pouring tea, overcoming the problem of the handle of the teapot swaying left and right when pouring tea.

Detailed implementation manners

[0018] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0019] Please refer to Figures 1 to 5 As shown, some embodiments of a teapot for preventing the kettle lid from falling off according to the present invention. The teapot includes: a kettle body 1 and a kettle lid 3; the kettle body 1 includes a kettle mouth 10, a kettle spout 12, an inner wall of the kettle 13, and a first sliding convex block 14. The first sliding convex block 14 protrudes from one side of the inner wall of the kettle 13. The kettle lid 3 includes a top of the kettle lid 31 and a wall of the kettle lid 33. The wall of the kettle lid 33 extends downward from one side of the top of the kettle lid 31 by a certain height. The wall of the kettle lid 33 further includes a bottom edge 331 and a first inclined groove 333. The first inclined groove 333 is obliquely opened on one side of the bottom edge 331 to the wall of the kettle lid 33. The first inclined groove 333 forms a first opening 335 at the free end on one side of the bottom edge 331, and a first bottom edge 337 is formed on the other side of the first inclined groove 333 relative to the first opening 335; the first inclined groove 333 can be slidably rotated into the first sliding convex block 14 through the first opening 335, and the first sliding convex block 14 can be movably clamped in the first bottom edge 337. Thus, the kettle lid 3 can be detachably covered on the kettle mouth 10 of the kettle body 1.

[0020] In some embodiments of the teapot according to the present invention, the direction in which the aforementioned first sliding bump 14 protrudes from the inner wall of the pot and the direction in which the spout 12 extends from the outside of the pot are parallel or the same, or the central axis of the first sliding bump 14 is parallel or the same as the water outlet line direction of the spout 12. The inclination direction of the first inclined groove 333 forms an inclination angle with respect to the central axis of the first sliding bump 14. In the state where the teapot is tilted to pour water, the first inclined groove 333 can be buckled by the first sliding bump 14 and thus fixed.

[0021] Thereby, during the process of the user operating to pour tea from the teapot, the first inclined groove 333 can be detachably clamped on the first sliding bump 14, preventing the lid 3 from displacing relative to the pot mouth 10. When the teapot is in use, the lid 3 will not fall off due to situations such as pouring tea or slight collision, causing tea to spill and scalding the user, etc. On the contrary, when the tea-pouring procedure is over, the user can gently rotate the lid 3 by hand, simultaneously driving the first inclined groove 333 to leave the first sliding bump 14, and the lid 3 can leave the pot mouth 10.

[0022] For the teapot of the present invention that prevents the lid from falling off, when uncovering the lid 3 and driving the first opening 335 of the first inclined groove 333 to slide into the first sliding bump 14 and buckle on the pot mouth 10, the user only needs to apply a little rotational force according to the usual operation form when holding the lid 3, without the need to add other operations, which is convenient and rapid. The lid 3 is firmly fixed on the pot mouth 10, and the effect is stable and reliable. Compared with the prior art, the teapot of the present invention that prevents the lid from falling off can avoid the lid 3 from falling off, tea from spilling, and prevent scalding during the process of pouring tea.

[0023] Please refer to Figures 1 to 5 As shown in an embodiment of the teapot of the present invention that prevents the lid from falling off, wherein the pot body 1 further includes a second sliding bump 17 that protrudes from the other side of the inner wall 13 of the pot; the lid 3 further includes a second inclined groove 332, which is obliquely opened from the other side of the bottom edge 331 towards the lid wall 33 to form the second inclined groove 332. The free end of the second inclined groove 332 on one side of the bottom edge 331 forms a second opening 334, and a second bottom edge 336 is formed on the other side of the second inclined groove 332 relative to the second opening 334. The second inclined groove 332 moves synchronously with the first inclined groove 333, and can be slidably rotated into the second sliding bump 17 from the second opening 334 of the second inclined groove 332. The second sliding bump 17 can be movably clamped in the second bottom edge 336, and at the same time, the first inclined groove 333 can be movably clamped in the first sliding bump 14 synchronously. The lid 3 is fixed in the pot mouth 10 in multiple directions, and the lid 3 can be more stably fixed in the pot mouth 10 during the process of pouring tea.

[0024] Some embodiments of a teapot for preventing the kettle lid from falling off. The teapot is made of various materials such as ceramics, metals, acrylics, or glass. In the embodiment drawings, the teapot is made of metal. The kettle lid 3 itself has a certain weight. When the user places the first opening 335 above the first sliding convex block 14 or the second opening 334 above the second sliding convex block 17, there is no support on the lower side of the kettle lid 3. If the user slightly loosens their fingers, due to the gravity of its own weight, the second inclined groove 332 of the kettle lid 3 synchronously moves under gravity with the first inclined groove 333. The first inclined groove 333 and the second inclined groove 332 can respectively slide into the first sliding convex block 14 from the first opening 335 by the weight of the kettle lid 3, and the first sliding convex block 14 can be movably clamped at the first bottom edge 337. At the same time, the second opening 334 can slide into the second sliding convex block 17 by itself, and the second sliding convex block 17 can be movably clamped at the second bottom edge 336. The kettle lid 3 can slide into the kettle mouth 10 by gravity and close, increasing the smooth effect of the kettle lid 3 combined with the kettle mouth 10 when using the teapot.

[0025] In some embodiments of the teapot for preventing the kettle lid from falling off according to the present invention, the direction in which the aforementioned first sliding convex block 14 protrudes from the inner wall of the kettle is parallel or the same as the direction in which the spout 12 extends from the kettle body 1, or the central axis of the first sliding convex block 14 is parallel or the same as the central axis of the water outlet of the spout 12. The inclination direction of the first inclined groove 333 forms an inclination angle with the tangent at the intersection of the central axis of the first sliding convex block 14 for combination; the direction in which the aforementioned second sliding convex block 17 protrudes from the inner wall 13 of the kettle is parallel or the same as the direction in which the spout 12 extends from the kettle body 1, or / and the central axis of the second sliding convex block 17 is parallel or the same as the central axis of the water outlet of the spout 12. The inclination direction of the second inclined groove 332 forms an inclination angle with the tangent at the intersection of the central axis of the aforementioned second sliding convex block 17 for combination.

[0026] In the state where the teapot is tilted to pour water, the first inclined groove 333 can be buckled and fixed by the aforementioned first sliding convex block 14, and the second inclined groove 332 can be buckled and fixed by the aforementioned second sliding convex block 17. Thus, during the process of the user operating to pour water or tea from the teapot, the displacement of the kettle lid 3 relative to the kettle mouth 10 is prevented, and the kettle lid 3 will not fall off and the tea will not spill out due to pouring tea or slight collision during the use of the kettle, scalding the user, etc.; on the contrary, after the tea-pouring procedure is completed, the user can gently rotate the kettle lid 3 with their hand, simultaneously driving the first inclined groove 333 away from the aforementioned first sliding convex block 14 and the second inclined groove 332 away from the second sliding convex block 17, and the kettle lid 3 can be removed from the kettle mouth 10.

[0027] Please refer to Figure 2 、 Figure 3 and Figure 7As shown, in an embodiment of a teapot of the present invention for preventing the kettle lid from falling off, at the lower edge end of the first opening 335, a first arc surface structure 3351 is formed, and at the lower edge end of the second opening 334, a second arc surface structure 3341 is formed. The first inclined groove 333 can be slidably rotated into the first sliding convex block 14 through the first opening 335. The first arc surface structure 3351 enables the first opening 335 to slide into the first sliding convex block 14 more smoothly and be clamped in the first inclined groove 333. The second inclined groove 332 can be slidably rotated into the second sliding convex block 17 through the second opening 334. The second arc surface structure 3341 enables the second opening 334 to slide into the second sliding convex block 17 more smoothly and be clamped in the second inclined groove 332.

[0028] Please refer to Figure 2 、 Figure 3 and Figure 7 As shown, in an embodiment of a teapot of the present invention for preventing the kettle lid from falling off, a closed bottom surface structure 3310 is formed on the circumference of the bottom edge 331. The circumferential closed bottom surface structure 3310 closes the bottom side of the kettle lid 3, further preventing water from seeping through the first inclined groove 333 or the second inclined groove 332 when pouring tea.

[0029] Please refer to Figure 2 and Figure 5 As shown, in an embodiment of a teapot of the present invention for preventing the kettle lid from falling off, the inner wall 13 of the kettle further includes an inner convex wall 19 that protrudes from the inner wall 13 of the kettle by a certain height. The kettle lid 3 can be detachably covered on the kettle mouth 10 of the kettle body 1, and the bottom edge 331 of the kettle lid 3 is detachably arranged on the inner convex wall 19. Among them, the shape of the inner convex wall 19 includes any one of a convex block, a convex wall, multiple convex blocks, or multiple convex walls protruding from the inner wall 13 of the kettle.

[0030] The teapot of the present invention is made of materials such as ceramics or glass and has a certain weight. In the embodiment where the kettle lid 3 is combined with the kettle mouth 10, the weight of the kettle lid 3 is transmitted from the first inclined groove 333 and the second inclined groove 332 to the first sliding convex block 14 and the second sliding convex block 17. A relatively large friction coefficient is generated due to pressure on the contact surface of the inner surface. The kettle lid 3 and its bottom edge 331 can be further supported by the inner convex wall 19, and at the same time, the friction force of the weight of the kettle lid 3 on the first sliding convex block 14 and the second sliding convex block 17 from the first inclined groove 333 and the second inclined groove 332 can be reduced. The user can more easily reverse and disengage the first inclined groove 333 and the second inclined groove 332 of the kettle lid 3 from the first sliding convex block 14 and the second sliding convex block 17 and take the kettle lid 3 from the kettle mouth 10.

[0031] Please refer to Figure 2 、 3As shown in FIGS. 4 and 5, an embodiment of a teapot of the present invention for preventing the kettle lid from falling off. The first inclined groove 333 and the second inclined groove 332 of the kettle lid 3 are hollow groove structures, and the hollow groove structures penetrate the structure of the kettle lid wall 33. When the water level in the teapot is relatively high and the tea water is close to the kettle lid 3, during the process of pouring the tea water, a small part of the tea water may seep out from the first inclined groove 333 and the second inclined groove 332 to the outside of the kettle spout 10. For this reason, the kettle lid 3 further includes a water stop ring 18, which is combined on the inner side of the kettle lid wall 33 and covers the inner sides of the first inclined groove 333 and the second inclined groove 332 to prevent the tea water from seeping out from the first inclined groove 333 and the second inclined groove 332 to the outside of the kettle spout 10. The water stop ring 18 can be made of any waterproof material such as a metal washer, a plastic washer, a silica gel washer or a rubber washer, etc.

[0032] Please refer to Figures 1 to 5 As shown in FIGS. 4 and 5, an embodiment of a teapot of the present invention for preventing the kettle lid from falling off. An arc-shaped groove 111 is formed on the inner side of the connecting portion 11, and the arc-shaped groove 111 extends upward to form a polygonal hole 113; polygonal structures 151 are formed at the free ends on both sides of the handle 15, and the volume of the polygonal structures 151 is less than or equal to the internal space of the arc-shaped groove 111, and the volume of the polygonal structures 151 is slightly less than or equal to the internal space of the polygonal hole 113. The polygonal structures 151 are movably assembled in the arc-shaped groove 111 of the connecting portion 11. When the handle 15 lifts the kettle body 1, the polygonal structures 151 can be detachably clamped in the polygonal hole 113.

[0033] In some embodiments, the polygonal structure 151 is a rectangle or a triangle, and the polygonal hole 113 corresponds to a rectangle or a triangle hole, for example, to fit the polygonal structure 151.

[0034] Please refer to Figures 1 - 6As shown, an embodiment of a teapot according to the present invention, wherein the pot body 1 further includes a set of connecting portions 11 and a handle 15. An inner side of the connecting portion 11 forms a connecting hole structure. A bottom side of the connecting portion 11 is an arc-shaped groove 111, and the arc-shaped groove 111 extends upward to form a polygon hole 113; free ends on both sides of the handle 15 respectively form polygon structures 151, and the polygon structures 151 can be correspondingly and adaptively combined in the polygon hole 113. The volume of the polygon structure 151 is less than or equal to the internal space of the arc-shaped groove 111, and the volume of the polygon structure 151 is slightly less than or equal to the internal space of the polygon hole 113. The polygon structure 151 is movably assembled in the arc-shaped groove 111 of the connecting portion 11. When the handle 15 lifts the pot body 1, the polygon structure 151 can be detachably clamped in the polygon hole 113, and the pot body 1 will not shake left and right relative to the handle 15, overcoming the problem of looseness and shaking at the connection between the handle and the pot body of a conventional teapot. On the contrary, when the pot body 1 is placed on a table, when the handle 15 is put down, the polygon structure 151 of the handle 15 can fall downward into the lower arc-shaped groove 111 by its own gravity, and at the same time, the handle 15 can be tilted and stored to either side.

[0035] In some embodiments, the polygon structure 151 includes, for example, a rectangle or a triangle, and the polygon hole 113 corresponds to, for example, a rectangular or triangular hole to adapt to the polygon structure 151.

[0036] In some embodiments, connection angles between sides of the polygon structure 151 form an arc surface structure. For example, four corners of a quadrilateral structure are modified into an arc surface structure. The polygon structure 151 is movably assembled in the arc-shaped groove 111 of the connecting portion 11. When the handle 15 lifts the pot body 1, the arc surface structure can more smoothly slide into the polygon hole 113, or the arc surface structure can more smoothly disengage from the polygon hole 113.

[0037] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is not necessary to list all the implementation manners one by one. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
