Description

Technical Field

[0001] This utility model relates to the field of drinking water containers, and in particular to an elastically deformable, threadless container lid. Background Technology

[0002] Cups and kettles have become essential drinking utensils for many people, but most commonly available ones have threaded caps. Users need to hold the container with one hand and the cap with the other, rotating them to open. This often requires multiple rotations, making it inconvenient. As a result, many threadless caps have emerged, such as the one in patent CN202410044096.5, entitled "An Electrically Unlocking Cap and Container." This cap features multiple, independently designed locking components for engaging the cup, making production and assembly difficult. Furthermore, the inner and outer caps are not detachable after production. Compared to the patented cap, after prolonged use, water stains and tea residue can seep into the cap through the perforations and locking components, leading to bacterial growth and odor, severely impacting hygiene and user experience. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an elastically deformable, threadless container lid, which solves the issues of numerous container lid components, difficult assembly, and inability to disassemble and clean.

[0004] The technical solution adopted by this utility model is: an elastically deformable threadless container lid, including a lid body and a movable part, the movable part including a sliding part and an extension part, the lid body being provided with a clearance opening for the extension part to pass through, the extension part having elastic deformation capability, the two ends of the extension part being a movable end and a connecting end respectively, the movable end being closer to the clearance opening than the connecting end; when the sliding part is driven to gradually move the connecting end away from the clearance opening, the movable end retracts towards the clearance opening.

[0005] Through the above technical solution, the movable part includes a sliding part and an extension part that are connected to each other. The extension part is used to engage with the opening of the container body. Installing the movable part as a whole into place at one time is equivalent to installing several extension parts into the specified positions simultaneously, which reduces the number of parts in the container lid and makes the assembly of the container lid simpler. The user drives the sliding part to slide the connecting hole, causing the extension part to undergo elastic deformation, which allows the movable end to retract and disengage from the container body, making it very convenient to use.

[0006] Furthermore, the extension portion is generally plate-shaped, and includes an integrally formed first section and a second section. The first section is connected to the connecting end, and the second section is connected to the movable end. The width of the first section is smaller than the width of the second section.

[0007] With the above technical solution, since the width of the first segment is smaller than that of the second segment, the first segment can produce a greater degree of deformation under the same force. When the user drives the sliding part, the extension part can more quickly make the movable end retract, making it more convenient and faster for the container lid and the container body to unlock each other.

[0008] Furthermore, an inclined surface is provided at the movable end, and the inclined surface is inclined downward.

[0009] The above technical solution avoids the situation where the moving end and the edge of the clearance opening are obstructed during use, making the use smoother.

[0010] Furthermore, the number of the extensions is at least two, and the extensions are evenly distributed in the circumferential direction around the sliding portion.

[0011] With the above technical solution, each extension is evenly distributed in the circumferential direction relative to the sliding part. When the sliding part is driven to move, the reaction force generated by each extension on the sliding part is more even in the circumferential direction, avoiding the situation where the sliding part gets stuck due to uneven force during the movement.

[0012] Furthermore, the cover includes a bottom cover and a splicing cover. The bottom cover has a notch, and the splicing cover has a protrusion. When the notch and the protrusion are spliced ​​together, the clearance is formed between the end of the protrusion and the bottom of the notch.

[0013] With the above technical solution, since the sliding part and the extension part are two inseparable parts on the moving part, if each extension part is directly inserted into the clearance opening, the elastic limit requirement of the extension part is high, and the assembly is difficult. During the assembly process, the extension part is prone to breakage. In the installation process of this container cover, each extension part is first aligned and placed into each notch, and then the notch is engaged with the convex plate to complete the assembly of the extension part and the clearance opening. This greatly reduces the assembly difficulty, and there is no need to bend the extension part, so as not to cause accidental breakage of the extension part.

[0014] Furthermore, the sidewall of the notch is provided with a strip-shaped recess, and the sidewall of the convex plate is provided with a rib; or, the sidewall of the convex plate is provided with a strip-shaped recess, and the sidewall of the notch is provided with a rib; during the splicing process of the notch and the convex plate, the rib is inserted into the strip-shaped recess.

[0015] With the above technical solution, after the bottom cover and splicing cover are connected to each other, the convex ribs and strip recesses fit together, making the splicing state of the edge of the convex plate and the edge of the notch more stable, and avoiding relative misalignment of the convex plate and the notch in the inner and outer directions.

[0016] Furthermore, the cover includes a top cover and a fixed cover. The fixed cover is connected to the bottom cover. The top cover is used to push against the sliding part. The edge of the top cover extends outward and is provided with a limiting part. The fixed cover is provided with a stop part. When the limiting part abuts against the stop part, the top cover is at its maximum height.

[0017] With the above technical solution, the top cover is larger in size, and the user can drive the sliding part to move by pressing the top cover, making it more convenient to use. The stop part has a limiting function on the limiting part, which can prevent the top cover from detaching on its own.

[0018] Furthermore, the splicing cover is provided with a first vertical groove, and the bottom cover is provided with a second vertical groove and a horizontal groove, the second vertical groove and the horizontal groove being interconnected; when the splicing cover and the bottom cover are connected, the first vertical groove and the second vertical groove are connected to each other, a limit protrusion is provided near the end of the horizontal groove, and a corresponding locking protrusion is provided on the inner wall of the fixing cover.

[0019] With the above technical solution, during the assembly process, the locking protrusion passes through the first vertical groove, the second vertical groove, and the horizontal groove in sequence. Finally, the locking protrusion is locked between the end of the horizontal groove and the limiting protrusion. By operating the fixing cover in reverse along this path, the fixing cover can be separated from the bottom cover and the splicing cover. The fixing cover is very easy to disassemble and assemble. Users can quickly disassemble the various parts on the container cover and clean the inside, thus removing water stains and tea stains inside the container cover, making it more hygienic to use.

[0020] Furthermore, the cover includes a retaining ring, the outer wall of which is in contact with the inner walls of both the bottom cover and the splicing cover.

[0021] Through the above technical solution, the connection between the notch edge and the convex plate edge is more stable, avoiding misalignment and making the connection more stable.

[0022] Furthermore, the cover is provided with a vent hole, and a movable rod is movably connected to the vent hole. A sealing block for sealing the vent hole is provided at the bottom end of the movable rod. A limit plate is provided on the movable rod, and an elastic element is provided between the limit plate and the cover. The upper surface of the limit plate abuts against the sliding part.

[0023] With the above technical solution, when the sliding part slides downward, the movable rod is driven to slide downward by pushing against the limiting plate, thereby realizing the separation of the sealing block and the vent hole. It is very convenient to use. At the same time as opening the container lid, the air pressure inside and outside the container is balanced through the vent hole, which effectively reduces the difficulty of opening the container lid. After the downward pressure on the sliding part disappears, the rebound force of the elastic element can be transmitted to the sliding part through the limiting plate, which helps the sliding part return to the initial position for repeated use.

[0041] refer to Figures 1-6A flexible, non-threaded container lid includes a lid body 1 and a movable part 2. The movable part 2 includes a sliding part 21 and an extension part 22. The lid body 1 is provided with a clearance opening 6 for the extension part 22 to pass through. The extension part 22 has elastic deformation capability. The two ends of the extension part 22 are a movable end 224 and a connecting end 222, respectively. The movable end 224 is closer to the clearance opening 6 than the connecting end 222. When the sliding part 21 is driven to make the connecting end 222 gradually move away from the clearance opening 6, the movable end 224 retracts towards the clearance opening 6.

[0042] The movable part 2 includes a sliding part 21 and an extension part 22 that are connected to each other. The extension part 22 is used to engage with the opening of the container body. Installing the movable part 2 into place as a whole at one time is equivalent to installing several extension parts 22 simultaneously to the specified position, which reduces the number of parts in the container lid and makes the assembly of the container lid simpler. The user drives the sliding part 21 to slide the connecting hole, which causes the extension part 22 to elastically deform, so that the movable end 224 can retract and disengage from the engagement with the container body, which is very convenient to use.

[0043] Depending on the specific shape design of the movable part 2, the relative positional relationship between the connecting end 222 and the movable end 224 in the initial state when the movable part 2 is not subjected to external force can be selected by the designer in the following three forms: 1. The height of the connecting end 222 is lower than the height of the movable end 224. Driving the sliding part 21 to move downward can drive the connecting end 222 to gradually move away from the clearance opening 6, so as to achieve the purpose of the movable end 224 retracting; 2. The height of the connecting end 222 is equal to the height of the movable end 224. Driving the sliding part 21 to move upward or downward can drive the connecting end 222 to gradually move away from the clearance opening 6, so as to achieve the purpose of the movable end 224 retracting; 3. The height of the connecting end 222 is higher than the height of the movable end 224. Driving the sliding part 21 to move downward can drive the connecting end 222 to gradually move away from the clearance opening 6, so as to achieve the purpose of the movable end 224 retracting; In this case, the height of the connecting end 222 is lower than the height of the movable end 224. In order to achieve the purpose of the movable end 224 retracting towards the clearance opening 6, the user needs to apply a downward driving force to the sliding part 21.

[0044] Preferably, the connecting end 222 is the junction of the extension 22 and the sliding part 21.

[0045] The extension 22 is plate-shaped and includes an integrally formed first section 221 and a second section 223. The first section 221 is connected to the connecting end 222, and the second section 223 is connected to the movable end 224. The width of the first section 221 is smaller than the width of the second section 223.

[0046] Because the width of the first segment 221 is smaller than that of the second segment 223, the first segment 221 can produce a greater degree of deformation under the same force. When the user drives the sliding part 21, the extension part 22 can more quickly make the movable end 224 retract, making it more convenient and faster for the container lid and the container body to unlock each other.

[0047] An inclined surface 225 is provided at the active end 224, and the inclined surface 225 is set downward at an angle.

[0048] To avoid any obstruction between the active end 224 and the edge of the clearance opening 6 during use, making the use smoother.

[0049] The number of extensions 22 is at least two, and the extensions 22 are evenly distributed in the circumferential direction around the sliding part 21.

[0050] Each extension 22 is evenly distributed in the circumferential direction relative to the sliding part 21. When the sliding part 21 is driven to move, the reaction force generated by each extension 22 on the sliding part 21 is more even in the circumferential direction, thus avoiding the situation where the sliding part 21 gets stuck due to uneven force during the movement.

[0051] refer to Figure 7 , 8 The cover 1 includes a bottom cover 11 and a splicing cover 12. The bottom cover 11 is provided with a notch 112, and the splicing cover 12 is provided with a protruding plate 121. When the notch 112 and the protruding plate 121 are spliced ​​together, the clearance opening 6 is formed between the end of the protruding plate 121 and the bottom of the notch 112.

[0052] Since the sliding part 21 and the extension part 22 are two inseparable parts on the moving part 2, if each extension part 22 is directly inserted into the relief opening 6, the elastic limit requirement of the extension part 22 is high, and the assembly is difficult. During the assembly process, the extension part 22 is easily broken. In the installation process of this container cover, each extension part 22 is first aligned and placed into each notch 112, and then the notch 112 is engaged with the protrusion 121 to complete the assembly of the extension part 22 and the relief opening 6. This greatly reduces the difficulty of assembly, and there is no need to bend the extension part 22, so as not to cause the extension part 22 to break accidentally.

[0053] The number of notches 112 and protrusions 121 is equal to the number of extensions 22.

[0054] refer to Figure 2 The sliding part 21 is hollow inside and is a vertically extending cylindrical shape. The lower part of the sliding part 21 forms an open port. The bottom cover 11 is provided with a columnar part 115. The upper end of the columnar part 115 extends into the sliding part 21. During the use of the container cover, the columnar part 115 always maintains sliding with the sliding part 21.

[0055] The side wall of the notch 112 is provided with a strip-shaped recess 113, and the side wall of the convex plate 121 is provided with a convex rib 122; or, the side wall of the convex plate 121 is provided with a strip-shaped recess 113, and the side wall of the notch 112 is provided with a convex rib 122; during the splicing process of the notch 112 and the convex plate 121, the convex rib 122 is inserted into the strip-shaped recess 113.

[0056] After the bottom cover 11 and the splicing cover 12 are connected to each other, the convex rib 122 and the strip recess 113 fit together, making the splicing state of the edge of the convex plate 121 and the edge of the notch 112 more stable, and avoiding relative misalignment of the convex plate 121 and the notch 112 in the inner and outer directions.

[0057] refer to Figure 5 , 7 8. Preferably, the strip-shaped recess 113 is provided on the inner wall on both sides of all the notches 112, and the ribs 122 are provided on the opposite side walls of all the convex plates 121.

[0058] The cover 1 includes a top cover 13 and a fixed cover 14. The fixed cover 14 is connected to the bottom cover 11. The top cover 13 is used to push against the sliding part 21. The edge of the top cover 13 extends outward and is provided with a limiting part 131. The fixed cover 14 is provided with a stop part 141. When the limiting part 131 abuts against the stop part 141, the top cover 13 is at its maximum height.

[0059] The top cover 13 is relatively large, and the user can drive the sliding part 21 to move by pressing the top cover 13, which makes it more convenient to use. The stop part 141 has a limiting effect on the limiting part 131, which can prevent the top cover 13 from detaching on its own.

[0060] refer to Figure 3 , 4 5, 7, 8, 9. The splicing cover 12 is provided with a first vertical groove 123, and the bottom cover 11 is provided with a second vertical groove 116 and a horizontal groove 117. The second vertical groove 116 and the horizontal groove 117 are interconnected. When the splicing cover 12 and the bottom cover 11 are connected, the first vertical groove 123 and the second vertical groove 116 are connected to each other. A limit protrusion 111 is provided near the end of the horizontal groove 117, and a corresponding locking protrusion 142 is provided on the inner wall of the fixed cover 14.

[0061] During assembly, the locking protrusion 142 passes sequentially through the first vertical groove 123, the second vertical groove 116, and the horizontal groove 117. Finally, the locking protrusion 142 is locked between the end of the horizontal groove 117 and the limiting protrusion 111. By operating the fixing cover 14 in the reverse direction, the fixing cover 14 can be detached from the bottom cover 11 and the splicing cover 12. The fixing cover 14 is very easy to disassemble and assemble. Users can quickly disassemble the various parts on the container cover and clean the inside, removing water stains and tea stains inside the container cover, making it more hygienic to use.

[0062] The cover 1 includes a retaining ring 15, the outer wall of which is in contact with the inner wall of both the bottom cover 11 and the splicing cover 12.

[0063] The connection between the edge of the notch 112 and the edge of the protrusion 121 is more stable, avoiding misalignment and making the connection more stable.

[0064] The cover 1 is provided with a vent hole 114, and a movable rod 3 is movably provided on the vent hole 114. A sealing block 4 for sealing the vent hole 114 is provided on the bottom end of the movable rod 3. A limiting plate 31 is provided on the movable rod 3. An elastic element 5 is provided between the limiting plate 31 and the cover 1. The upper surface of the limiting plate 31 abuts against the sliding part 21.

[0065] When the sliding part 21 slides downward, it drives the movable rod 3 to slide downward by pushing against the limiting plate 31, thereby realizing the separation of the sealing block 4 and the vent 114. It is very convenient to use. While opening the container lid, the air pressure inside and outside the container is balanced through the vent 114, which effectively reduces the difficulty of opening the container lid. After the downward pressure on the sliding part 21 disappears, the rebound force of the elastic element 5 can be transmitted to the sliding part 21 through the limiting plate 31, which helps the sliding part 21 return to the initial position for repeated use.

[0066] Ventilation holes 114 are provided on the bottom cover 11.

[0067] Preferably, in the initial state where the container lid is not subjected to external force, the top of the movable rod 3 abuts against the top cover 13. When the user presses down on the top cover 13, the sealing effect of the sealing block 4 on the vent hole 114 can be released. The venting action is very fast and convenient to use.

[0068] The preferred elastic element 5 is a spring sleeved on the movable rod 3.

[0069] refer to Figures 1-10 The assembly process of the container lid of this utility model is as follows: First, a spring is sleeved on the movable rod 3, and the bottom end of the movable rod 3 passes through the vent hole 114 and connects to the sealing block 4. Next, each extension 22 is aligned and inserted into the notch 112 to allow the movable part 2 to be placed as a whole into the bottom cover 11. Then, the protruding plate 121 is aligned with the notch 112 and fitted together, during which the protruding rib 122 is aligned and inserted into the strip-shaped recess 113. Then, the retaining ring 15 is placed into the bottom cover 11 and the splicing cover 12, so that the retaining ring 15 fits against the inner sidewall of the bottom cover 11 and the splicing cover 12. Finally, the top cover 13 is overlapped on the sliding part 21, and the fixed cover 14 is operated so that the locking protrusion 142 passes sequentially through the first vertical groove 123, the second vertical groove 116, and the horizontal groove 117, and finally the locking protrusion 142 is locked between the end of the horizontal groove 117 and the limiting protrusion 111.

[0070] When in use, the user presses down the top cover 13, pushing the sliding part 21 to slide downwards. The extension part 22 undergoes elastic deformation as a whole, and the connecting end 222 gradually moves away from the clearance opening 6. The movable end 224 is driven to retract inwards towards the clearance opening 6 until it locks with the container body. The container body is used in conjunction with the container. Locking and disengaging with the container body by changing the position of the movable end 224 is a common technology and will not be described in detail here. During this process, the downward-moving top cover 13 pushes the movable rod 3, causing the sealing block 4 to separate from the vent 114, thereby achieving the balance and adjustment of the air pressure inside and outside the container body.

[0071] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
