A teapot design that prevents the lid from coming off

Abstract

To provide a teapot structure capable of preventing the lid of the teapot from coming off and tea from overflowing during the process of pouring tea, thereby avoiding burns. [Solution] This invention is a teapot structure that prevents the lid from coming off. The lid 3 has a diagonal groove 333, and a sliding protrusion 14 protruding from the inner wall of the pot body 1. The sliding protrusion is detachably fitted into the diagonal groove of the lid, and the diagonal groove forms an angle with the central axis of the sliding protrusion, preventing the lid from moving relative to the pot opening 10. When the user tilts the teapot to pour tea, the lid will not come off due to tea water spillage or a slight bump. Conversely, after pouring tea, the user can gently rotate the lid with their hand, causing the diagonal groove to disengage from the sliding protrusion, allowing the lid to be removed from the pot opening.

Description

[Technical Field]

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

[0002] When pouring water, the teapot must be tilted toward the spout, allowing the tea water inside the teapot to flow out. This tilt causes the pot body and the lid to tilt at a certain angle. Therefore, external force must be applied to hold the lid down to prevent it from coming off during the pouring process. However, users often forget to hold the lid down, resulting in the lid coming off and cracking, or the tea water spilling out of the teapot spout and splashing. Furthermore, if the tea being brewed in the pot is very hot, pouring the tea while holding the lid down increases the risk of burns.

[0003] Currently, some teapot lids are designed with a locking mechanism that snaps into place between the lid and the mouth of the pot, allowing the user to manually rotate the lock to secure the lid. This solves the problem of the lid and mouth of the pot closing tightly. Additionally, some teapots have handles that can be moved left and right for storage, but when the user grips the handle while pouring tea, the connection between the handle and the pot body loosens, causing the lid to swing back and forth, resulting in an unstable pour.

[0004] [Patent Document 1] Utility Model Registration No. 3219798 Summary of the Invention [Problem to be solved by the invention]

[0005] To overcome the drawbacks and inconveniences of the above-mentioned known structures, the present invention provides a teapot structure that prevents the lid from coming off. [Means for solving the problem]

[0006] To achieve the above objectives, the present invention provides a teapot structure that prevents the lid from coming off, and aims to overcome or at least resolve the problems existing in the existing technology, providing a teapot that prevents the lid from coming off, tea water from spilling, and burns when pouring tea. The present invention also provides a teapot that prevents the lid from coming off, and provides that the lid automatically slides onto the spout of the pot using gravity to close tightly. The structure of the teapot to prevent the lid from coming off in accordance with the present invention comprises a pot body and a pot lid. The pot body has a pot spout, a spout, an inner wall, and a first sliding protrusion, the first sliding protrusion protruding from one side of the inner wall. The pot lid has a top and a wall of the lid, the wall of the lid having a base and a first diagonal groove, the wall of the lid extending in one direction from the top of the lid and having a height, the free end of which forms the bottom. One side of the bottom has a first diagonal groove opening diagonally into the wall of the lid, the free end of the first diagonal groove forming a first opening on one side of the bottom. The opposite side of the first diagonal groove forms a first base, the first diagonal groove can movably slide onto the first sliding protrusion through the first opening, and the first sliding protrusion movably engages with the first base, so that the pot lid can be separated and tightly closed over the mouth of the pot body.

[0007] The second object of this invention is to provide a teapot with a lid that will not fall off. In some embodiments, the lid automatically slides onto the opening of the teapot using gravity. The teapot can be made of various materials, such as ceramic, metal, acrylic, or glass. The lid itself has a certain weight, so that when the user places the first opening on the first sliding protrusion or the second opening on the second sliding protrusion, the underside of the lid is left unsupported.

[0008] When the user releases his / her fingers slightly, the pot lid's weight causes the second diagonal groove to move in synchronization with the first diagonal groove by gravity. The first diagonal groove and the second diagonal groove automatically slide into the first sliding protrusion from the first opening, respectively, using the weight of the pot lid, and the first sliding protrusion movably engages with the first base edge. At the same time, the second opening automatically slides into the second sliding protrusion, and the second sliding protrusion movably engages with the second base edge.

[0009] The third object of this invention is that the lid of the teapot can automatically slide into the mouth of the pot using gravity, and separate from the mouth of the pot body to tightly close the lid. Compared with conventional teapots, the anti-lid fall-off teapot of this invention has the effect of allowing the lid and the pot mouth to be connected more smoothly.

[0010] This invention also provides a teapot that stabilizes the teapot body and prevents the handle from swinging back and forth when pouring tea, thus overcoming the problem of the handle swinging back and forth when the user holds it to pour tea.

[0011] A fourth object of the present invention is that in some embodiments of the present invention, the connecting part of the teapot body and the handle have a connecting hole formed inside the connecting part, an arc-shaped groove at the bottom of the connecting hole, which extends upward to form a polygonal hole, and the free ends of the handle have polygonal structures whose volume is smaller than the space within the arc-shaped groove and slightly smaller than the space within the polygonal hole.

[0012] The polygonal structure is movably mounted in the arc-shaped groove of the connecting portion, so that when the handle lifts the pot body, the polygonal structure can be detachably engaged in the polygonal hole. [Effects of the Invention]

[0013] Compared with the prior art, the advantages of this invention are as follows: the teapot handle can be moved left and right and stored, and the polygonal structures on the free ends on both sides of the handle allow the user to hold the handle to lift the teapot when pouring tea, and these polygonal structures fit firmly and detachably into the polygonal holes on both sides of the teapot, preventing the handle from loosening and swaying left and right. The user can hold the handle stably to lift the teapot and pour tea, thus overcoming the problem of the teapot handle swaying left and right when pouring tea. [Brief explanation of the drawings]

[0015] The structure, features and effects of the present invention will be described in detail below with reference to the best embodiment and drawings. [Example]

[0016] As shown in Figures 1 to 5, in some embodiments, the present invention relates to a teapot structure for preventing the lid from coming off. The teapot includes a pot body 1 and a pot lid 3. The pot body 1 includes a pot mouth 10, a spout 12, an inner wall 13, and a first sliding protrusion 14. The first sliding protrusion 14 protrudes from one side of the inner wall 13.

[0017] The pot lid 3 includes a pot lid top 31 and a pot lid wall 33, the pot lid wall 33 having a base 331 and a first oblique groove 333, the pot lid wall 33 extending downward from the pot lid top 31, and its free end forming the bottom 331. On one side of the bottom 331, a first oblique groove 333 is formed, opening obliquely into the pot lid wall 33, a first opening 335 is formed at the free end of the first oblique groove 333, and a first bottom 337 is formed on the opposite side of the first oblique groove 333.

[0018] The first oblique groove 333 can movably slide onto the first sliding protrusion 14 through the first opening 335, and the first sliding protrusion 14 can movably engage with the first base edge 337, so that the pot lid 3 can separate from the pot mouth 10 of the pot body 1 to tightly close the lid.

[0019] According to some embodiments of the teapot of the present invention, the direction in which the first sliding protrusion 14 protrudes from the pot inner wall 13 is parallel to or the same as the direction in which the spout 12 extends outward from the pot body 1, and / or the axis of the first sliding protrusion 14 is parallel to or the same as the direction in which the water flows through the spout 12. The inclination direction of the first oblique groove 333 is inclined at a certain angle relative to the axis of the first sliding protrusion 14, so that when the teapot is tilted to pour tea, the first oblique groove 333 can engage with the first sliding protrusion 14 and fix the pot lid 3.

[0020] As a result, when the user tilts the teapot to pour tea, the first diagonal groove 333 separates and engages with the first sliding protrusion 14, preventing the pot lid 3 from moving relative to the pot mouth 10. Even when tilting the teapot to pour tea or in the event of a slight collision, the pot lid 3 will not fall off, the tea water will not spill, and the user will not be burned. On the other hand, when the user has finished pouring tea, the user can gently turn the pot lid 3 with their hand to disengage the first diagonal groove 333 from the first sliding protrusion 14 and remove the pot lid 3 from the pot mouth 10.

[0021] The teapot's lid-preventing mechanism of the present invention involves opening the lid 3, rotating the first opening 335 of the first oblique groove 333, and engaging the first sliding protrusion 14 to securely fasten it to the teapot mouth 10. This operation requires only a slight rotation in the usual manner, requiring no additional steps, making it quick and convenient. The lid 3 is securely fastened to the teapot mouth 10, providing stable and reliable results. Compared with the prior art, the teapot of the present invention can prevent the lid 3 from falling off, spilling teawater, and burns when pouring tea.

[0022] As shown in Figures 1 to 5, in one embodiment of the teapot structure of the present invention to prevent the teapot lid from coming off, the pot body 1 further includes a second sliding protrusion 17, which protrudes from the opposite side of the pot inner wall 13, and the pot lid 3 further includes a second oblique groove 332, which opens obliquely into the wall 33 of the pot lid on the opposite side of the bottom edge 331 to form the second oblique groove 332, which forms a second opening 334 at the free end of the bottom edge 331, and a second base edge 336 is formed on the opposite side of the second oblique groove 332. The second oblique groove 332 operates in synchronization with the first oblique groove 333, and can movably slide onto the second sliding protrusion 17 through the second opening 334 of the second oblique groove 332, and the second sliding protrusion 17 movably engages with the second base edge 336. At the same time, the first oblique groove 333 also movably engages with the first sliding protrusion 14, so that the pot lid 3 is firmly fixed in the pot mouth 10 in multiple directions, and the pot lid 3 can be more stably fixed to the pot mouth 10 during the process of pouring tea.

[0023] In one embodiment of the teapot structure of the present invention for preventing the lid from coming off, the teapot can be made of various materials such as ceramic, metal, acrylic, glass, etc., and the drawings show the teapot made of metal. The lid 3 of the teapot has a certain weight. When the user places the first opening 335 on the first sliding protrusion 14 and / or the second opening 334 on the second sliding protrusion 17, there is no support on the underside of the lid 3. When the user releases his / her grip, the lid 3 will fall due to gravity and the second diagonal groove 332 and the first diagonal groove 333 will operate simultaneously due to gravity. The first diagonal groove 333 and the second diagonal groove 332 can respectively slide from the first opening 335 onto the first sliding protrusion 14 by utilizing the weight of the lid 3, and the first sliding protrusion 14 can movably engage with the first base 337. At the same time, the second opening 334 can also movably slide onto the second sliding protrusion 17, and the second sliding protrusion 17 can movably engage with the second base 336. In this way, the teapot lid 3 can naturally slide onto the teapot mouth 10 under its own weight and close tightly, which enhances the effect of smoother connection between the teapot lid and the teapot mouth 10.

[0024] In one embodiment of the teapot structure for preventing the lid from coming off according to the present invention, the direction in which the first sliding protrusion 14 protrudes from the pot inner wall 13 and the direction in which the pot spout 12 extends outward from the pot body 1 are parallel or in the same direction, or the central axis of the first sliding protrusion 14 is parallel or in the same direction as the central axis of the pot spout 12 in the direction of water flow. The inclination direction of the first oblique groove 333 forms an inclination angle with the tangent at the intersection with the central axis of the first sliding protrusion 14. Furthermore, the direction in which the second sliding protrusion 17 protrudes from the pot inner wall 13 and the direction in which the pot spout 12 extends outward from the pot body 1 are parallel or in the same direction, and / or the central axis of the second sliding protrusion 17 is parallel or in the same direction as the central axis of the pot spout 12 in the direction of water flow. The inclination direction of the second oblique groove 332 forms an inclination angle with a tangent at the portion where it intersects with the central axis of the second sliding protrusion 17, and is connected.

[0025] When the teapot is tilted to pour water, the first oblique groove 333 of the lid 3 is locked and fixed by the first sliding protrusion 14, and the second oblique groove 332 is locked and fixed by the second sliding protrusion 17. This prevents the lid 3 from moving relative to the teapot opening 10 when the user tilts the teapot to pour water or tea, preventing the lid 3 from coming off, the tea water from spilling, and the user from being burned even if water is poured or a slight bump occurs while using the teapot. Conversely, after pouring, the user can gently rotate the lid 3, and at the same time, the first oblique groove 333 disengages from the first sliding protrusion 14 and the second oblique groove 332 disengages from the second sliding protrusion 17, allowing the lid 3 to be removed from the teapot opening 10.

[0026] 2, 3, and 7, in one embodiment of the teapot structure for preventing the lid from coming off in accordance with the present invention, a first arc-shaped structure 3351 is formed at the lower end of the first opening 335 and a second arc-shaped structure 3341 is formed at the lower end of the second opening 334. The first oblique groove 333 is movably rotated and slid onto the first sliding protrusion 14 via the first opening 335. The first arc-shaped structure 3351 helps the first opening 335 to slide smoothly onto the first sliding protrusion 14 and snap into the first oblique groove 333. The second oblique groove 332 is movably rotated and slid onto the second sliding protrusion 17 via the second opening 334, and the second arc-shaped structure 3341 helps the second opening 334 to slide smoothly onto the second sliding protrusion 17 and snap into the second oblique groove 332.

[0027] As shown in Figures 2, 3 and 7, in one embodiment of the structure of the teapot to prevent the lid of the present invention from coming off, the periphery of the bottom edge 331 is formed as a closed bottom structure 3310, which seals the bottom of the teapot lid 3 and further prevents water from seeping out from the first diagonal groove 333 or the second diagonal groove 332 when tea is poured. As shown in Figures 2 and 5, the structure of the teapot to prevent the lid of the present invention from coming off is In one embodiment of the structure, the pot inner wall 13 further includes an inner protrusion 19, which protrudes from the pot inner wall 13 to a certain height, the pot lid 3 can be separated to cover the pot mouth 10 of the pot body 1, and the base 331 of the pot lid 3 is placed separately on the inner protrusion 19, where the shape of the inner protrusion 19 is any structure protruding from the pot inner wall 13, including a protrusion, a protrusion hedge, or multiple protrusions or hedges.

[0028] The teapot of the present invention is made of a material such as ceramic or glass and has a certain weight. In an embodiment in which the teapot lid 3 is attached to the teapot opening 10, the weight of the teapot lid 3 is transmitted to the first and second sliding masses 14 and 17 through the first and second inclined grooves 333 and 332. The pressure increases the coefficient of friction where the inner surfaces contact. The teapot lid 3 and its bottom edge 331 are further supported by the inner protrusion 19, which reduces the frictional force exerted by the first and second inclined grooves 333 and 332 on the first and second sliding masses 14 and 17 due to the weight of the teapot lid 3. As a result, a user can easily invert the first and second inclined grooves 333 and 332 of the teapot lid 3 to remove them from the teapot opening 10.

[0029] As shown in Figures 2, 3 and 5, in one embodiment of the teapot structure for preventing the lid from coming off according to the present invention, the first and second inclined grooves 333, 332 of the lid 3 are hollow grooves with a through structure that penetrate the wall 33 of the lid. When the teawater level in the teapot is high and approaches the lid 3, some of the teawater may leak out of the first and second inclined grooves 333, 332 during tilting. To prevent this, a water stop ring 18 is added to the lid 3. The water stop ring 18 is attached to the inside of the wall 33 of the lid, covering the inside of the first and second inclined grooves 333, 332. The water stop ring 18 is made of any waterproof material, such as a metal washer, plastic washer, silicone washer or rubber washer, to prevent the teawater from leaking out of the first and second inclined grooves 333, 332.

[0030] 1 to 5, in one embodiment of the teapot structure for preventing the lid from coming off according to the present invention, a connecting hole is formed inside the connecting part 11, and an arc-shaped trough 111 is formed at the bottom of the connecting hole, which extends upward to form a polygonal hole 113. A polygonal structure 151 is formed at each free end of the handle 15, and the volume of the polygonal structure 151 is smaller than the internal space of the arc-shaped trough 111 and slightly smaller than the internal space of the polygonal hole 113. The polygonal structure 151 is movably disposed within the arc-shaped trough 111 of the connecting part 11, and can be separated and fixed within the polygonal hole 113 when the handle 15 is lifted. In some embodiments, the polygonal structure 151 is rectangular or triangular, and the polygonal hole 113 is, for example, a rectangular or triangular hole that fits into the polygonal structure 151 .

[0031] As shown in Figures 1 to 6, in one embodiment of the teapot structure for preventing the lid from coming off according to the present invention, the pot body 1 further comprises a pair of connecting part 11 and handle 15. The inside of the connecting part 11 is formed with a connecting hole, and the bottom side of the connecting hole has an arc-shaped groove 111, which extends upward to form a polygonal hole 113. The handle 15 has polygonal structures 151 formed at both free ends, the volume of which is smaller than the internal space of the arc-shaped groove 111 and slightly smaller than the internal space of the polygonal hole 113. The polygonal structures 151 are movably fitted into the arc-shaped grooves 111 of the connecting part 11, so that when the handle 15 is lifted, the polygonal structures 151 are separated and fitted into the polygonal hole 113, and the pot body 1 does not swing back and forth relative to the handle 15, unlike the conventional teapot. This overcomes the problem of loosening or shaking at the connection between the handle 15 and the pot body 1. Conversely, when the pot body 1 is placed on a table and the handle 15 is lowered, the polygonal structure 151 of the handle 15 falls into the arc-shaped groove 111 below due to its own weight, and the handle 15 can be stored by tilting it to either the left or right side.

[0032] In some embodiments, the polygonal structure 151 includes, for example, a rectangle or a triangle, and the corresponding polygonal hole 113 is, for example, a rectangular or triangular hole, thereby fitting into the polygonal structure 151. In addition, in some embodiments, the connecting angles between the sides of the polygonal structure 151 are formed as arcuate structures, for example, the four corners of a quadrilateral structure are modified as arcuate structures. The polygonal structure 151 is movably inserted into the arcuate groove 111 of the connecting part 11, and the arcuate structure allows the arcuate structure to more smoothly slide into or out of the polygonal hole 113 when the handle 15 is lifted.

[0033] The above-described embodiments of the present invention are merely examples for clarifying the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art can make various modifications and changes based on the above description, and all implementation methods will be omitted. All modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are included in the scope of the claims of the present invention.
