Description

Technical Field

[0001] This utility model relates to the field of training cup technology, and in particular to a training cup. Background Technology

[0002] Chinese Patent Document No. CN119867491A disclosed a novel training cup on April 25, 2025, comprising a cup body, a lid, and a sealing element. The lid is fixed to the top of the cup body, and the sealing element is disposed between the cup body and the lid. An inner cavity is provided inside the cup body, and a water outlet cavity is formed between the lid and the sealing element. A sealing element is provided at the lower part of the sealing element. The sealing element can be deformed into a first form and a second form. When the sealing element is deformed into the first form, the inner cavity and the water outlet cavity are interconnected. When the sealing element is deformed into the second form, the sealing element closes the water outlet cavity so that the inner cavity and the water outlet cavity are not interconnected. This new training cup allows the sealing element to deform and switch between a first and a second form by pressing down or pulling up the operating part. When the sealing element is deformed into the first form, the inner cavity and the water outlet cavity are connected, allowing water from the inner cavity to enter the water outlet cavity and enabling the user to drink normally. When the sealing element is deformed into the second form, the sealing element closes the water outlet cavity, preventing the inner cavity from connecting with the water outlet cavity. In this case, water from the inner cavity cannot enter the water outlet cavity, making it impossible to drink. The operation of pressing down or pulling up the operating part to deform the sealing element is relatively laborious, resulting in inconvenience. Moreover, after prolonged use, the elasticity of the sealing element will deteriorate, potentially causing it to fail to close the water outlet cavity when deformed.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a training cup that is simple in structure, easy to operate, has a good sealing effect, is easy to carry, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] A training cup designed for this purpose includes a cup body, a lid, and a sealing element. The lid is fixed to the top of the cup body, and the sealing element is disposed on the lid. An inner cavity is provided inside the cup body, and a water outlet cavity is formed between the lid and the sealing element. The sealing element is characterized by having an opening and closing component, and a lifting and lowering fitting between the opening and closing component and the lid. When the opening and closing component rotates, it moves up and down on the lid body via the lifting and lowering fitting. When the opening and closing component rises, the sealing element moves upward to open the water outlet cavity, thereby connecting the inner cavity to the water outlet cavity. When the opening and closing component descends, the sealing element moves downward to close the water outlet cavity, thereby preventing the inner cavity and the water outlet cavity from communicating.

[0006] The lifting and lowering mechanism includes a first thread on the opening and closing component and a second thread on the cover. When the opening and closing component rotates, the first thread and the second thread engage with each other to allow the opening and closing component to move up and down on the cover.

[0007] The opening and closing parts are provided with several protrusions around their perimeter, and the cover is provided with several locking positions on its inner side; when the opening and closing parts rise to the corresponding position to connect the inner cavity with the water outlet cavity, the protrusions are locked in the locking positions.

[0008] When the protrusion is in the locked position: when the opening and closing part rotates forward and descends to the corresponding position, the inner cavity and the water outlet cavity are not connected; when the opening and closing part rotates in the reverse direction and continues to rise to the corresponding position, the opening and closing part is disassembled and separated from the cover.

[0009] The opening and closing component has several limiting ribs distributed in a ring, and the bottom of the cover is provided with a limiting surface. When the opening and closing component descends to the corresponding position, the limiting ribs press down against the limiting surface.

[0010] The sealing element has a sealing edge, and the cover has a sealing surface. When the sealing element moves downward to the corresponding position, the sealing edge presses against the sealing surface, so that the inner cavity and the water outlet cavity are not connected. When the sealing element moves upward, the sealing edge leaves the sealing surface, so that the inner cavity is connected to the water outlet cavity.

[0011] The cover is provided with a number of first through holes and / or second through holes in a ring shape; when the sealing edge leaves the sealing surface, the inner cavity is connected to the water outlet cavity through the first through holes and / or second through holes.

[0012] The inner side of the cover is provided with several sets of positioning structures. The positioning structure includes two protruding ribs that are spaced apart from each other. A locking position is formed between the two protruding ribs. When the protruding point is locked in the locking position: when the opening and closing part rotates in the forward direction, the locking position passes over the protruding rib on one side in the forward direction. When the opening and closing part rotates in the reverse direction, the locking position passes over the protruding rib on the other side in the reverse direction.

[0013] The opening and closing mechanism is equipped with a lifting column, and the cover is equipped with a movable hole. The lifting column is movably mounted on the movable hole. The first thread is mounted on the outer surface of the lifting column, and the second thread is mounted on the wall of the movable hole.

[0014] The sealing element has a sealing mating edge, and the cover has an upper edge. A water outlet cavity is formed between the sealing mating edge and the upper edge, and the end of the sealing mating edge abuts against the upper edge. When the sealing mating edge is subjected to a sufficiently large external force, a water outlet gap is formed between the sealing mating edge and the upper edge, and the water outlet cavity is connected to the outside through the water outlet gap.

[0015] This invention relates to a training cup with an opening and closing mechanism. When the opening and closing mechanism rotates, it moves up and down on the lid via a lifting mechanism. When the opening and closing mechanism rises, the sealing element moves upward to open the water outlet chamber, thus connecting the inner cavity to the water outlet chamber. When the opening and closing mechanism falls, the sealing element moves downward to close the water outlet chamber, thus preventing the inner cavity from communicating with the water outlet chamber. This structure opens or closes the water outlet chamber by rotating the opening and closing mechanism, causing the sealing element to move up and down. It does not open or close the water outlet chamber by deforming the sealing element, making operation effortless and more convenient. It also eliminates the problem of the sealing element failing to close the water outlet chamber due to loss of elasticity after prolonged use. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-10This training cup includes a cup body 1, a lid 2, and a sealing element 3. The lid 2 is fixed to the top of the cup body 1, and the sealing element 3 is disposed on the lid 2. The cup body 1 has an inner cavity 17 for holding water. A water outlet cavity 5 is formed between the lid 2 and the sealing element 3. An opening and closing element 4 is disposed on the sealing element 3. The opening and closing element 4 and the sealing element 3 are integrally disposed, and the opening and closing element 4 and the sealing element 3 are made of different materials and are bonded together as a single part by adhesive bonding. Alternatively, the opening and closing element 4 and the sealing element 3 are separately assembled, and a lifting mechanism is provided between the opening and closing element 4 and the lid 2. When the opening and closing part 4 rotates, it moves up and down on the cover 2 via the lifting and lowering mechanism. When the opening and closing part 4 rises, the sealing part 3 moves upward to open the water outlet chamber 5, thereby connecting the inner cavity 17 with the water outlet chamber 5. At this time, the water in the inner cavity 4 can enter the water outlet chamber 5, and the user can drink normally. When the opening and closing part 4 falls, the sealing part 3 moves downward to close the water outlet chamber 5, thereby preventing the inner cavity 17 from communicating with the water outlet chamber 5. At this time, the water in the inner cavity 4 cannot enter the water outlet chamber 5, so drinking is not possible, and the water on the inner cavity 4 will not leak out of the training cup.

[0028] The lifting and lowering mechanism includes a first thread 6 on the opening and closing member 4 and a second thread 7 on the cover 2. When the opening and closing member 4 rotates, the first thread 6 and the second thread 7 cooperate with each other to make the opening and closing member 4 move up and down on the cover 2.

[0029] The opening and closing component 4 has several protrusions 8 arranged in a ring around its periphery, and the cover 2 has several locking positions 9 arranged in a ring on its inner side. When the opening and closing component 4 rises to the corresponding position to connect the inner cavity 17 with the water outlet cavity 5, the protrusions 8 are locked in the locking positions 9, so that the user will have a certain feel when rotating the opening and closing component 4. At the same time, the feel indicates to the user that the water outlet cavity 5 has been opened. In addition, this structure also restricts the upward movement of the opening and closing component 4.

[0030] When the protrusion 8 is locked in position 9: when the opening and closing part 4 rotates forward and descends to the corresponding position, the inner cavity 17 and the water outlet cavity 5 are not connected; when the opening and closing part 4 rotates in the opposite direction and continues to rise to the corresponding position, the opening and closing part 4 and the cover 2 are disassembled and separated.

[0031] The bottom of the opening and closing component 4 has several limiting ribs 10 distributed in a ring. The bottom of the cover 2 is provided with a limiting surface 11. When the opening and closing component 4 descends to the corresponding position, the limiting ribs 10 press down against the limiting surface 11, which can restrict the opening and closing component 4 from continuing to move downward. At the same time, the water outlet cavity 5 is already closed.

[0032] The sealing element 3 has a sealing edge 12 on its outer periphery and a sealing surface 13 on the cover 2. The sealing surface 13 is set facing upward and the sealing edge 12 is set downward. When the sealing element 3 moves downward to the corresponding position, the sealing edge 12 presses against the sealing surface 13 downward, so that the inner cavity 17 and the water outlet cavity 5 are not connected. When the sealing element 3 moves upward, the sealing edge 12 leaves the sealing surface 13, so that the inner cavity 17 is connected to the water outlet cavity 5.

[0033] A movable ring 25 is provided on the outside of the opening and closing part 4, and a movable groove 26 is provided on the cover 2. When the opening and closing part 4 moves up and down on the cover 2, the movable ring 25 moves up and down on the movable groove 26. The limiting rib 10 is provided at the bottom of the movable ring 25, and the limiting surface 11 is the bottom surface of the movable groove 26.

[0034] The cover 2 is provided with a number of first through holes 14 and second through holes 15 in a ring. When the sealing edge 12 leaves the sealing surface 13, the inner cavity 17 is connected to the water outlet cavity 5 through the first through hole 14, and the inner cavity 17 is connected to the water outlet cavity 5 in sequence through the second through hole 15 and the movable groove 26.

[0035] The inner side of the cover 2 is provided with several sets of positioning structures. The positioning structure includes two protruding ribs 16 that are spaced apart from each other. A locking position 9 is formed between the two protruding ribs 16. When the protrusion 8 is locked in the locking position 9, when the opening and closing part 4 rotates in the forward direction, the locking position 9 passes over the protruding rib 16 on one side in the forward direction. When the opening and closing part 4 rotates in the reverse direction, the locking position 9 passes over the protruding rib 16 on the other side in the reverse direction.

[0036] A first guide surface 18 is provided on both sides of the protrusion 8, and a second guide surface 19 is provided on the protruding rib 16. The second guide surfaces 19 are located on both sides of the locking position 9. The protrusion 8 is locked onto or away from the locking position 9 through the cooperation of the first guide surface 18 and the second guide surface 19. When the protrusion 8 is locked onto the locking position 9, the opening and closing part 4 rotates and rises, so that the opening and closing part 4 and the cover 2 can be disassembled. When the protrusion 8 is locked onto the locking position 9, the opening and closing part 4 can be disassembled by rotating it slightly. In this embodiment, when the opening and closing part 4 is rotated clockwise, the opening and closing part 4 descends, and when the opening and closing part 4 is rotated counterclockwise, the opening and closing part 4 rises. When the protrusion 8 is locked onto the locking position 9, the opening and closing part 4 is rotated counterclockwise, and the opening and closing part 4 rises, thereby disassembling the opening and closing part 4 and the cover 2. The protrusion 8 is provided around the movable ring 25, and the protruding rib 16 is provided on the side wall of the movable groove 26.

[0037] The lower part of the opening and closing component 4 is provided with a lifting column 20, and the bottom of the cover body 2 is provided with a movable hole 21. The lifting column 20 is movably mounted on the movable hole 21. The first thread 6 is provided on the outer surface of the lifting column 20, and the second thread 7 is provided on the hole wall of the movable hole 21. The first thread 6 is an external thread, and the second thread 7 is an internal thread. The lifting column 20 is located on the lower side of the movable ring 25, and the movable hole 21 is located at the bottom of the movable groove 26.

[0038] The top of the opening and closing member 4 is provided with an operating part 22 for rotating the opening and closing member 4. The operating part 22 is a lug, which facilitates rotating the opening and closing member 4.

[0039] The top of the cup body 1 is provided with a third thread 27, and the bottom of the lid body 2 is provided with a fourth thread 28. The lid body 2 is fixed to the top of the cup body 1 by the cooperation of the third thread 27 and the fourth thread 28. The third thread 27 is an internal thread, and the fourth thread 28 is an external thread.

[0040] When the opening / closing element 4 and the sealing element 3 are assembled separately, the bottom of the sealing element 3 is provided with a retaining ring 29, and the top of the opening / closing element 4 is provided with a retaining groove 30. The retaining ring 29 is engaged in the retaining groove 30 to connect the sealing element 3 and the opening / closing element 4.

[0041] The sealing element 3 is provided with a sealing mating edge 23, and the cover 2 is provided with an upper edge 24. A water outlet cavity 5 is formed between the sealing mating edge 23 and the upper edge 24, and the end of the sealing mating edge 23 abuts against the upper edge 24. When the sealing mating edge 23 is subjected to a sufficiently large external force, a water outlet gap is formed between the sealing mating edge 23 and the upper edge 24, and the water outlet cavity 5 is connected to the outside through the water outlet gap. When the user sucks on the end of the sealing element 3, a pressure difference is generated inside the water outlet cavity 5, which causes the liquid in the water outlet cavity 5 to open the end of the sealing element 3 (forming a water outlet gap) and be discharged outward, thereby realizing drinking water. The above principle can be referred to patent CN110913729B, which will not be described in detail here.

[0042] It also includes a top cover 31, which is fitted onto the top of the cover body 2. The top cover 31 is snapped into the cover body 2. When the user wants to drink water, the top cover 31 needs to be removed first.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
