Description

Technical Field

[0001] This utility model relates to the field of drinking water container technology, specifically to a water cup. Background Technology

[0002] Currently, in addition to the conventional screw-on lids, magnetic lid water bottles are becoming increasingly common for easier opening. To ensure easy opening, the magnetic force is usually not too strong. However, this also means there's a chance the magnetic lid might be accidentally opened, for example: when the water bottle is in a backpack side pocket and bumps into other objects; or when the bottle is full and you instinctively try to lift the bottle by only the magnetic lid, excessive force can cause the lid to detach from the bottle, leading to it falling or even breaking. Utility Model Content

[0003] This application aims to at least solve the problem that the magnetic cover in the above-mentioned prior art or related art is easily opened by mistake.

[0004] The first aspect of this utility model provides a water cup, including: a cup body assembly; a cup lid that can be detachably fitted onto the cup body assembly; and a limiting band, the two ends of which are movably connected to opposite sides of the cup body assembly, such that the limiting band can switch between a first position and a second position. In the first position, the limiting band can be fastened to the top of the cup lid to restrict the opening of the cup lid, and in the second position, the limiting band is removed from the top of the cup lid to allow the cup lid to be removed.

[0005] The water cup proposed in this embodiment includes a cup body assembly, a cup lid, and a limiting band. The limiting band is connected to the cup body assembly and has a semi-circular shape with an opening at one end near the cup body assembly. This shape allows the limiting band to be fastened to the top of the cup lid. The limiting band fastening to the top of the cup lid restricts the displacement of the cup lid relative to the cup body assembly, firmly restraining the cup lid on the cup body assembly and preventing the cup lid from falling off the cup body assembly. This effectively prevents the cup lid from being accidentally opened. Furthermore, when it is necessary to remove the cup lid, simply push the limiting band downwards to disengage it from the cup lid, thus not affecting the removal of the cup lid. The operation is simple and convenient.

[0006] In some embodiments, the cup lid and the cup body assembly are magnetically connected; or the cup lid and the cup body assembly are plugged in; or the cup lid and the cup body assembly are snapped together. Magnetic, plugged, or snap-connected connections between the cup lid and the cup body assembly all offer advantages such as easy opening of the cup lid, convenient operation, and the elimination of the need for threaded connections, resulting in a simpler cup lid structure. Combined with the limiting band in the embodiments of this application, this effectively solves the problem of accidental opening of the cup lid. Furthermore, for the magnetically connected structure, when the cup lid is placed on the cup body assembly, simply placing the cup lid on the cup body assembly using magnetic attraction is sufficient to achieve proper engagement. During use, the cup lid can be directly removed from the cup body assembly. Compared to threaded connections, magnetic connections are more convenient, faster, and less strenuous.

[0007] In some embodiments, the retaining band is elastic, and when the retaining band is fitted over the top of the cup lid, the retaining band can be stretched to apply downward pressure to the top of the cup lid. The elastic retaining band can more securely hold the cup lid in place, and the ability to stretch the retaining band moderately makes it easier to fit the retaining band onto the cup lid.

[0008] In some embodiments, a recessed relief groove is provided on the top wall of the cup lid. When the limiting band is sleeved on the cup lid, the limiting band is located above the relief groove and has an insertion gap between it and the groove wall of the relief groove, allowing the user's finger to lift the limiting band by inserting it into the relief groove.

[0009] In these embodiments, by providing a relief groove on the top wall of the cup lid, the retaining strap can also be used as a handle for easy carrying of the water cup. The relief groove allows the operator's fingers to pass through and grip the retaining strap, enabling the operator to lift the water cup with one hand or even one finger, making it more convenient to carry. Specifically, the width of the relief groove is greater than the width of the retaining strap, thus forming an insertion gap between the relief groove and the retaining strap, allowing the user's fingers to be inserted through the relief groove to lift the retaining strap.

[0010] In some embodiments, two protrusions are provided on the outer side wall of the cup assembly, and the two protrusions are located on opposite sides of the cup assembly. The two ends of the limiting band are respectively connected to the two protrusions. With this configuration, the limiting band can be installed simply by providing two protrusions on the side wall of the cup assembly, resulting in a simple structure.

[0011] In some embodiments, the cup assembly includes a cup body and a cup mouth seat. The cup mouth seat is sleeved on the outer wall of the cup mouth portion of the cup body. The cup mouth seat includes a seat body sleeved and connected to the cup mouth portion and an extension protruding outward in the radial direction of the seat body. The protrusion is disposed on the outer wall of the extension and the extension is located between the lower end of the cup lid and the cup body to isolate the cup lid and the cup body.

[0012] In these embodiments, the cup holder is mostly made of plastic. The protrusion can be integrally injection molded onto the cup holder, making it easier to process and manufacture. By fitting the cup holder onto the cup rim, the cup holder is positioned on the upper part of the cup body, and the protrusion is closer to the lid, thus minimizing the length of the limiting band. Furthermore, the extension of the cup holder is located between the lower end of the lid and the cup body, preventing the lower end of the lid from directly contacting the cup body, thereby minimizing paint wear caused by repeated closing of the lid during prolonged use.

[0013] In some embodiments, the protrusion includes a connecting post connected to the extension and a stop cap disposed on the connecting post at one end away from the extension, the outer diameter of the stop cap being larger than the outer diameter of the connecting post; both ends of the limiting band are provided with through holes, and the limiting band is sleeved on the connecting post through the through holes to be rotatably connected with the connecting post.

[0014] In these embodiments, the protrusion includes a connecting post and a stop cap. The limiting band is sleeved on the connecting post through a through hole. The stop cap is located outside the connecting post and stops the limiting band, preventing it from detaching from the connecting post and thus limiting its position. The cooperation between the through hole and the connecting post also allows the limiting band to rotate around the connecting post. Rotating the limiting band allows it to be sleeved on the cup lid and detached from the cup lid, facilitating operation.

[0015] In some embodiments, a limiting rib is provided on one of the outer side wall of the cup mouth and the inner side wall of the seat body, and a limiting groove is provided on the other side to cooperate with the limiting rib, so as to connect the seat body and the cup mouth.

[0016] In these embodiments, the cup holder is sleeved on the outer side wall of the cup mouth and fixedly connected. Specifically, a limiting rib is provided on the inner side wall of the holder body and a limiting groove is provided on the outer side wall of the cup mouth. After the cup holder is assembled with the cup mouth, the limiting rib is inserted into the limiting groove, which can limit the vertical displacement of the cup holder relative to the cup mouth.

[0017] In some embodiments, a first magnetic element is provided in the cup lid, and a second magnetic element is provided in the cup body assembly. At least one of the first and second magnetic elements is a magnet, and the other is a magnet or a metal part. The first and second magnetic elements can magnetically engage. This configuration allows the first and second magnetic elements to magnetically connect the cup lid and the cup body assembly, resulting in low cost and a complete container.

[0018] In some embodiments, the cup assembly further includes: a cup body having an opening at one end; an inner plug assembly capable of being inserted into the opening of the cup body and sealing the opening; a second magnetic chuck disposed on top of the inner plug assembly; and a cup lid including an outer lid and an inner lid, with a receiving cavity formed between the inner lid and the outer lid, a first magnetic chuck disposed in the receiving cavity and connected to the inner lid and / or the outer lid.

[0019] In these embodiments, the cup lid includes an outer lid, an inner lid, and a first magnetic element. The first magnetic element is disposed in the receiving cavity formed between the inner lid and the outer lid, so that the first magnetic element is not exposed and is not easily bumped, thus preventing it from falling off. Furthermore, a second magnetic element on the cup body assembly is disposed on the top of the inner plug assembly, and the top of the inner plug assembly is closer to the top of the cup lid, which is conducive to magnetic connection with the magnetic element located on the cup lid.

[0039] The following will combine Figures 1 to 5 A water cup describing some embodiments of this application.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the first aspect of this utility model provides a water cup, including a cup body assembly 10, a cup lid 20, and a limiting band 30. The cup lid 20 can be detachably closed onto the cup body assembly 10. The two ends of the limiting band 30 are movably connected to the opposite sides of the cup body assembly 10, so that the limiting band 30 can switch between a first position and a second position. In the first position, the limiting band 30 can be fastened to the top of the cup lid 20 to restrict the opening of the cup lid 20. In the second position, the limiting band 30 is removed from the top of the cup lid 20 to allow the cup lid 20 to be removed.

[0041] The water cup proposed in this embodiment includes a cup body assembly 10, a cup lid 20, and a limiting band 30. The limiting band 30 is connected to the cup body assembly 10 and has a semi-circular shape with one end open near the cup body assembly 10. This shape allows the limiting band 30 to be fastened to the top of the cup lid 20. The limiting band 30 fastening to the top of the cup lid 20 can restrict the displacement of the cup lid 20 relative to the cup body assembly 10, firmly restraining the cup lid 20 on the cup body assembly 10 and preventing the cup lid 20 from falling off the cup body assembly 10. This can effectively prevent the cup lid 20 from being accidentally opened. Furthermore, when it is necessary to remove the cup lid 20, it is only necessary to push the limiting band 30 downward to disengage the limiting band 30 from the cup lid 20, so as not to affect the removal of the cup lid 20. The operation is simple and convenient.

[0042] In some embodiments, the lid 20 and the cup body assembly 10 are magnetically connected. For example, magnetic elements capable of magnetic attraction can be provided on the lid 20 and the cup body assembly 10 respectively to achieve magnetic connection between the lid 20 and the cup body assembly 10; or, the lid 20 and the cup body assembly 10 are plugged in. For example, parts of the sidewalls of the lid 20 and the cup body assembly 10 overlap to form a plugged connection. At least one of the parts where the outer sidewall of the cup body assembly 10 overlaps with the inner sidewall of the lid 20 has a protrusion, so that the cup body assembly 10 and the lid 20 are connected by a protrusion. The plug-in connection between the two parts has a certain bonding force and will not easily fall off; or, the cup lid 20 and the cup body assembly 10 are snapped together. For example, the side walls of the cup lid 20 and the cup body assembly 10 overlap to form a plug-in connection. A first protrusion is provided on the outer side wall of the cup body assembly 10, and a second protrusion is provided on the inner side wall of the cup lid 20. When the cup lid 20 is closed on the cup body assembly 10, the second protrusion extends downward over the first protrusion so that the cup lid 20 and the cup body assembly 10 are snapped together, which initially prevents the cup lid 20 from falling off.

[0043] In these embodiments, the cup lid 20 and the cup body assembly 10 are magnetically connected, plugged in, or snapped together. All of these have the advantages of making the cup lid 20 easy to open, convenient to operate, and requiring no threaded connection structure on the cup lid 20, thus making the structure of the cup lid 20 relatively simple. When combined with the limiting band 30 in the embodiments of this application, it can effectively solve the problem of the cup lid 20 being accidentally opened.

[0044] Furthermore, regarding the magnetic connection between the cup lid 20 and the cup body assembly 10, when the cup lid 20 is placed on the cup body assembly 10, it is only necessary to use the magnetic attraction to simply place the cup lid 20 on the cup body assembly 10 to achieve the proper engagement of the cup lid 20 and the cup body assembly 10. When in use, the cup lid 20 can be directly pulled off the cup body assembly 10. Compared with the threaded connection method, the magnetic connection method is convenient, quick, and labor-saving.

[0045] It is understandable that when there is a threaded connection between the cup lid 20 and the cup body assembly 10, there may be a problem that the cup lid 20 may be accidentally opened. In this case, the threaded connection structure, in conjunction with the limiting band 30 of the present application embodiment, can also effectively solve the problem of the cup lid 20 being accidentally opened.

[0046] Furthermore, in some embodiments, the limiting band 30 is elastic, and when the limiting band 30 is fastened to the top of the cup lid 20, the limiting band 30 can be stretched to apply downward pressure to the top of the cup lid 20. The elastic limiting band 30 can more firmly fix the cup lid 20, and the limiting band 30 can be stretched moderately, making it easier to fasten the limiting band 30 to the cup lid 20.

[0047] As an example, the limiting band 30 may optionally be a silicone elastic band or a rubber elastic band. Both silicone and rubber elastic bands have good elasticity, which can firmly fix the cup lid 20 and also have the advantage of being waterproof. Alternatively, the limiting band 30 may also be made of elastic bands such as nylon elastic bands or polyester elastic bands.

[0048] As an example, the limiting band 30 may optionally be a flat strip structure, which can be more stably tightened on the cup lid 20 and easily fits the outer surface of the cup lid 20, which is beneficial for limiting the cup lid 20 by the limiting band 30.

[0049] To facilitate carrying the water bottle, in some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a recessed relief groove 210 is provided on the top wall of the cup lid 20. When the limiting band 30 is fastened on the cup lid 20, the limiting band 30 is located above the relief groove 210 and has an insertion gap between it and the groove wall of the relief groove 210, allowing the user's finger to lift the limiting band 30 by inserting it into the relief groove 210.

[0050] In these embodiments, by providing a relief groove 210 on the top wall of the cup lid 20, the limiting strap 30 can also be used as a handle for easy carrying of the water cup. The relief groove 210 allows the operator's fingers to pass through and grip the limiting strap 30, thereby enabling the operator to lift the water cup with one hand or even one finger, making it more convenient to carry. Specifically, the width of the relief groove 210 is greater than the width of the limiting strap 30, thereby forming an insertion gap between the relief groove 210 and the limiting strap 30, allowing the user's fingers to lift the limiting strap 30 by inserting them into the relief groove 210.

[0051] Furthermore, as an example, optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connection surface between the side wall of the relief groove 210 and the top wall of the cup lid 20 is designed as an arc surface 211 to prevent the operator from hurting their hand when lifting the cup between the relief groove 210 and the limiting band 30, thus affecting the user experience.

[0052] Regarding the connection structure between the cup body assembly 10 and the limiting band 30, in some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, two protrusions 123 are provided on the outer side wall of the cup assembly 10. The two protrusions 123 are located on opposite sides of the cup assembly 10, and the two ends of the limiting band 30 are respectively connected to the two protrusions 123. With this configuration, the limiting band 30 can be installed by providing two protrusions 123 on the side wall of the cup assembly 10, which is a simple structure.

[0053] Furthermore, regarding the connection structure between the cup assembly 10 and the limiting band 30, in some embodiments, such as... Figure 3 , Figure 4 and Figure 5 As shown, the cup assembly 10 includes a cup body 110 and a cup mouth seat 120. The cup mouth seat 120 is sleeved on the outer wall of the cup mouth portion 111 of the cup body 110. The cup mouth seat 120 includes a seat body 121 sleeved and connected to the cup mouth portion 111, and an extension portion 122 protruding outward in the radial direction of the seat body 121. The protrusion portion 123 is disposed on the outer wall of the extension portion 122. The extension portion 122 is located between the lower end of the cup lid 20 and the cup body 110 to isolate the cup lid 20 and the cup body 110.

[0054] In these embodiments, the cup holder 120 is mostly made of plastic. The protrusion 123 can be integrally injection molded onto the cup holder 120, making it easier to process and manufacture. The cup holder 120 is fitted onto the cup mouth 111, placing it on top of the cup body 110 and bringing the protrusion 123 closer to the lid 20, thus minimizing the length of the limiting band 30. Furthermore, the extension 122 of the cup holder 120 is located between the lower end of the lid 20 and the cup body 110, preventing the lower end of the lid 20 from directly contacting the cup body 110. This minimizes paint wear caused by repeated sealing of the lid 20 during prolonged use.

[0055] Furthermore, regarding the structure of the protrusion 123, in some embodiments, such as Figure 5 As shown, the protrusion 123 includes a connecting post 1231 connected to the extension 122, and a stop cap 1232 disposed on the end of the connecting post 1231 away from the extension 122. The outer diameter of the stop cap 1232 is larger than the outer diameter of the connecting post 1231. Both ends of the limiting band 30 are provided with through holes. The limiting band 30 is sleeved on the connecting post 1231 through the through holes so as to be rotatably connected with the connecting post 1231.

[0056] In these embodiments, the protrusion 123 includes a connecting post 1231 and a stop cap 1232. The limiting band 30 is sleeved on the connecting post 1231 through a through hole. The stop cap 1232 is located outside the connecting post 1231 and stops the limiting band 30, preventing the limiting band 30 from detaching from the connecting post 1231, thus limiting the limiting band 30. The cooperation between the through hole and the connecting post 1231 also allows the limiting band 30 to rotate around the connecting post 1231. Rotating the limiting band 30 allows it to be sleeved on the cup lid 20 and detached from the cup lid 20, facilitating operation.

[0057] Of course, this application is not limited to this. For the movable connection between the limiting band 30 and the cup body assembly 10, in addition to the connection structure described above which provides through holes at both ends of the limiting band 30 and two protrusions 123 on the outer side wall of the cup body assembly 10, the two ends of the limiting band 30 can also be slidably connected to the cup body assembly 10. For example, the side wall of the cup body assembly 10 is provided with a sliding groove, and the two ends of the limiting band 30 are provided with sliding pieces that can slide in the sliding groove; or, the two ends of the limiting band 30 are snapped to the two ends of the cup body assembly 10, and one of the limiting band 30 and the cup body assembly 10 is provided with a snap and the other is provided with a buckle. The snap is inserted into the buckle to achieve a snap connection.

[0058] Regarding the connection structure between the cup holder 120 and the cup mouth 111, in some embodiments, such as Figure 5As shown, the cup body 110 also includes a cup body portion 113 located at the lower part and a cup shoulder portion 112 connecting the cup mouth portion 111 and the cup body portion 113. The outer diameter of the cup mouth portion 111 is smaller than the outer diameter of the cup body portion 113. A limiting rib 124 is provided on one of the outer side wall of the cup mouth portion 111 and the inner side wall of the seat body 121, and a limiting groove 1111 that can cooperate with the limiting rib 124 is provided on the other side to connect the seat body 121 and the cup mouth portion 111.

[0059] In these embodiments, the cup holder 120 is sleeved on the outer side wall of the cup mouth portion 111 and fixedly connected. Specifically, a limiting rib 124 is provided on the inner side wall of the holder body 121, and a limiting groove 1111 is provided on the outer side wall of the cup mouth portion 111. After the cup holder 120 is assembled with the cup mouth portion 111, the limiting rib 124 is inserted into the limiting groove 1111, which can limit the vertical displacement of the cup holder 120 relative to the cup mouth portion 111.

[0060] Furthermore, the limiting rib 124 and the limiting groove 1111 are tightly fitted together, thereby limiting the circumferential rotation of the cup seat 120 relative to the cup mouth 111. Alternatively, one of the limiting rib 124 and the limiting groove 1111 is provided with a protruding rib, and the other is provided with a groove. The protruding rib is inserted into the groove, which can limit the circumferential rotation of the cup seat 120 relative to the cup mouth 111.

[0061] It is understood that, despite the above embodiments and accompanying drawings Figure 5 The example given is that a limiting rib 124 is provided on the inner side wall of the seat body 121 and a limiting groove 1111 is provided on the outer side wall of the cup mouth 111. However, the positions of the limiting rib 124 and the limiting groove 1111 can be interchanged. That is, the limiting groove 1111 is provided on the inner side wall of the seat body 121 and the limiting rib 124 is provided on the outer side wall of the cup mouth 111. This is also an embodiment of this application, and will not be described in detail here.

[0062] Furthermore, the outer diameter of the cup mouth 111 is set smaller than the outer diameter of the cup body 113. The cup mouth seat 120 is fitted onto the side wall of the cup mouth 111 with the smaller outer diameter. The cup lid 20 is fitted onto the outer circumference of the cup mouth seat 120, so that the outer diameter of the cup lid 20 can be approximately the same as the outer diameter of the cup body 113. After the cup lid 20 is fitted, the upper and lower parts of the cup are coordinated in size, and the aesthetics are better.

[0063] In some embodiments, the cup lid 20 is provided with a first magnetic element 250, and the cup body assembly 10 is provided with a second magnetic element 131. At least one of the first magnetic element 250 and the second magnetic element 131 is a magnet, and the other is a magnet or a metal part. The first magnetic element 250 and the second magnetic element 131 can magnetically engage. With this configuration, the first magnetic element 250 and the second magnetic element 131 can magnetically connect the cup lid 20 and the cup body assembly 10, which is low-cost and facilitates container assembly.

[0064] As an example, the magnet can optionally be a permanent magnet such as a magnet, which has advantages such as stable magnetic attraction, small size, no need for external power supply, and simple structure. The metal part can be an iron block, which has a simple structure and low cost.

[0065] In some embodiments, such as Figure 3 and Figure 4 As shown, the cup assembly 10 further includes: a cup body 110, one end of which has an opening; an inner plug assembly 130, which can be inserted into the opening of the cup body 110 and seal the opening; a second magnetic 131 is disposed on the top of the inner plug assembly 130; and a cup lid 20 including an outer lid 220 and an inner lid 230, with a receiving cavity 240 formed between the inner lid 230 and the outer lid 220, and a first magnetic 250 disposed in the receiving cavity 240 and connected to the inner lid 230 and / or the outer lid 220.

[0066] In these embodiments, the cup lid 20 includes an outer lid 220, an inner lid 230, and a first magnetic 250. The first magnetic 250 is disposed in the receiving cavity 240 formed between the inner lid 230 and the outer lid 220, so that the first magnetic 250 is not exposed and is not easily bumped, thus preventing it from falling off. Furthermore, the second magnetic 131 on the cup body assembly 10 is disposed on the top of the inner plug assembly 130. The top of the inner plug assembly 130 is closer to the top of the cup lid 20, which is conducive to magnetic connection with the magnetic body located on the cup lid 20.

[0067] Furthermore, in some embodiments, the inner plug assembly 130 includes an inner plug and an inner cover. The inner plug has an outlet, and the inner cover can be fastened to the inner plug assembly 130. The inner cover can be flipped open or flipped closed. The cup lid 20 covers the outside of the inner plug assembly 130. In this structure, the second magnetic 131 can also be provided on the inner cover.

[0068] Furthermore, in some embodiments, a button 132 is provided on the top of the inner cover. Pressing the button 132 can open the inner cover, thereby allowing water to be poured out through the outlet. The second magnetic body 131 can be disposed in the button 132 and wrapped in the button 132 by in-mold injection molding. When the cup lid 20 is placed on the cup body assembly 10, the button 132 and the cup lid 20 can be attracted together.

[0069] As an example, optionally, both the outer cover 220 and the inner cover 230 are stainless steel covers. Further, the cup lid 20 also includes a magnetic retaining ring 260. First, the magnetic retaining ring 260 is welded to the inside of the outer cover 220 or the inner cover 230. Then, the first magnetic element 250 is fixed in the magnetic retaining ring 260, and finally, the inner cover 230 and the outer cover 220 are welded together.

[0070] Furthermore, regarding the specific placement of the first magnetic clasp 250 and the second magnetic clasp 131, besides the first magnetic clasp 250 being placed on top of the cup lid 20 and the second magnetic clasp 131 being placed on top of the inner plug assembly 130 in the above embodiment, they can also be placed at other locations on the cup lid 20 and the cup body assembly 10. For example, the first magnetic clasp 250 can be placed on the cup lid 20 and extend circumferentially along the side wall of the cup lid 20, and the second magnetic clasp 131 can be placed around the cup mouth 111 of the cup body 110 and located within the inner ring of the first magnetic clasp 250, with the first magnetic clasp 250 and the second magnetic clasp 131 facing each other internally and externally. Alternatively, the first magnetic clasp 250 can be placed at the lower end of the cup lid 20, and the second magnetic clasp 131 can be placed at the upper end of the cup shoulder 112 or in the cup mouth seat 120, with the first magnetic clasp 250 and the second magnetic clasp 131 facing each other vertically. This is also an embodiment of this application, and these implementations and other achievable methods are obvious to those skilled in the art.

[0071] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
