Description

Technical Field

[0001] The invention relates to the field of drinking water containers, in particular to a container with a quick-detachable cover. Background Art

[0002] Nowadays, cups and pots are daily necessities and have become essential drinking utensils that many people carry with them. However, most of the common ones on the market are threaded caps. When using, the user needs to grasp the container with one hand and grasp the container lid with the other hand and rotate them relative to each other to open the two. Usually, the container lid needs to be rotated multiple times relative to the container to open it, which is not convenient to use. As a result, many non-threaded container caps have appeared on the market. For example, application number CN202410044096.5 is entitled a container cap and container with electric unlocking, in which locking members for clamping the cup body are independently arranged and there are multiple locking members. Overall, there are many accessories in the container cap, which makes its production and assembly difficult. Moreover, after the container cap is produced, the inner cover body and the outer cover body cannot be disassembled from each other. Compared with the container cap in the patent, after a long period of use, water stains and tea stains will enter the interior of the container cap through the gap between the perforation and the locking member, and then breed bacteria and odor, seriously affecting the hygiene and use experience. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a container with a quick-detachable cover, which solves the problem that the container cover has numerous parts and is difficult to assemble and cannot be disassembled and washed.

[0004] The technical solution adopted by the present invention is: a container with a quick-release cover, comprising a cover, a movable part and a container body, wherein an annular convex rib is arranged at the opening of the container body, the movable part comprises a sliding part and an extension part, and the cover body is provided with an escape opening for the extension part to pass through, the extension part has elastic deformation capability, the two ends of the extension part are respectively a movable end and a connecting end, and the movable end is closer to the escape opening than the connecting end; when the sliding part is driven to make the connecting end gradually move away from the escape opening, the movable end contracts toward the escape opening and disengages from the annular convex rib.

[0005] Through the above technical solution, the movable part includes a sliding part and an extension part that are interconnected, wherein the movable end on the extension part is used to clamp the annular convex rib, and installing the movable part as a whole at one time is equivalent to installing several extension parts to the specified position simultaneously, thereby reducing the number of components in the container cover and making the assembly of the container cover simpler; the user drives the sliding part to slide the connecting hole to make the extension part produce elastic deformation, so that the movable end can be retracted and disengaged from the clamping connection with the annular convex rib, which is very convenient to use.

[0006] Furthermore, the extension portion is arranged in a plate shape as a whole, and includes a first section and a second section which are integrally formed, the first section is connected to the connecting end, the second section is connected to the movable end, and the width of the first section is smaller than the width of the second section.

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

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

[0009] Through the above technical solution, the situation where the movable end and the edge of the avoidance opening are blocked during use can be avoided, making the use smoother.

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

[0011] Through the above technical solution, each extension part is evenly distributed in the circumferential direction relative to the sliding part. When the sliding part is driven to move, the reaction of each extension part on the sliding part is more uniform in the circumferential direction, avoiding the sliding part from getting stuck due to uneven force during movement.

[0012] Furthermore, the cover body includes a bottom cover and a splicing cover, the bottom cover is provided with a notch, the splicing cover is provided with a convex plate, and when the notch and the convex plate are spliced ​​together, the avoidance is formed between the end of the convex plate and the bottom of the notch.

[0013] Through the above technical solution, since the sliding part and the extension part are two inseparable parts on the movable part, if each extension part is directly connected and inserted into the avoidance opening, the elastic limit requirement for the extension part is high, and the assembly difficulty is large, and it is easy to directly cause the extension part to break during the assembly process; during the installation process of the container cover, each extension part is first aligned and placed in each notch, and then the notch is connected and clamped with a convex plate to complete the assembly of the extension part and the avoidance opening, which greatly reduces the difficulty of assembly, and there is no need to bend the extension part, which will not cause accidental breakage of the extension part.

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

[0015] Through the above technical solution, after the bottom cover and the splicing cover are connected to each other, the convex ribs and the strip-shaped recesses are interlocked with each other, making the state of the edges of the convex plate and the edges of the notch spliced ​​together more stable, avoiding relative misalignment of the convex plate and the notch in the inside-outside direction.

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

[0017] Through the above technical solution, the volume of the top cover is larger, and the user can drive the sliding part to move by pressing the top cover, which makes it more convenient to use. The stopper has a limiting effect on the limiting part, which can prevent the top cover from detaching alone.

[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 transverse groove, and the second vertical groove and the transverse groove are connected to each other; when the splicing cover and the bottom cover are connected, the first vertical groove and the second vertical groove are butted against each other, a limiting protrusion is provided near the end of the transverse groove, and a locking protrusion is correspondingly provided on the inner wall of the fixed cover.

[0019] Through 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, and finally the locking protrusion is stuck between the end of the horizontal groove and the limiting protrusion. The fixed cover can be separated from the bottom cover and the splicing cover by operating the fixed cover in reverse along this path. The disassembly and assembly of the fixed cover is very convenient. The user can quickly disassemble the various components on the container cover and clean the inside, even remove water stains and tea stains inside the container cover, making it more hygienic to use.

[0020] Furthermore, the cover body comprises a retaining ring, and an outer wall of the retaining ring is simultaneously fitted with inner walls of the bottom cover and the splicing cover.

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

[0022] Furthermore, the cover body is provided with an air hole, the air hole is movably provided with a movable rod, a sealing block for sealing the air hole is provided on the bottom end of the movable rod, a limiting plate is provided on the movable rod, an elastic member is provided between the limiting plate and the cover body, and the upper surface of the limiting plate abuts against the sliding part.

[0023] Through the above technical solution, when the sliding part slides downward, the movable rod is driven to slide downward by pushing the limit plate, thereby realizing the mutual separation of the sealing block and the air vent, which is very convenient to use. When the container cover is opened, the air pressure inside and outside the container is balanced through the air vent, effectively reducing the difficulty of opening the container cover; after the downward pressure on the sliding part disappears, the rebound force of the elastic part can be transmitted to the sliding part through the limit plate, and the auxiliary sliding part returns to the initial position upward for repeated use.

[0043] refer to Figure 1 , 2, 3, 4, 5, 6, 11, 12, a container with a quick-release cover, comprising a cover 1, a movable part 2 and a container body 7, wherein an annular convex rib 71 is arranged at the opening of the container body 7, the movable part 2 comprises a sliding portion 21 and an extension portion 22, and a avoidance opening 6 for the extension portion 22 to pass through is arranged on the cover 1, the extension portion 22 has elastic deformation capability, and the two ends of the extension portion 22 are respectively a movable end 224 and a connecting end 222, and the movable end 224 is closer to the avoidance opening 6 than the connecting end 222; when the sliding portion 21 is driven to make the connecting end 222 gradually move away from the avoidance opening 6, the movable end 224 contracts toward the avoidance opening 6 and disengages from the annular convex rib 71.

[0044] The movable part 2 includes a sliding part 21 and an extension part 22 that are connected to each other, wherein the movable end 224 on the extension part 22 is used to engage with the annular convex rib 71. Installing the movable part 2 as a whole at one time is equivalent to installing several extension parts 22 to the specified position simultaneously, which reduces the number of components in the container cover and makes the assembly of the container cover simpler. The user drives the sliding part 21 to slide the connecting hole so that the extension part 22 produces elastic deformation, so that the movable end 224 can be retracted and disengaged from the engagement with the annular convex rib 71, which is very convenient to use.

[0045] According to the different specific shape designs of the movable part 2, the relative position relationship between the connecting end 222 and the movable end 224 presented in the initial state where the movable part 2 is not subjected to external force has the following three forms for the designer to choose: 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 avoidance opening 6, so as to achieve the purpose of retracting the movable end 224; 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 avoidance opening 6, so as to achieve the purpose of retracting the movable end 224; 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 avoidance opening 6, so as to achieve the purpose of retracting the movable end 224; in this case, it is preferred that the height of the connecting end 222 is lower than the height of the movable end 224. In order to achieve the purpose of retracting the movable end 224 to the avoidance opening 6, the user needs to apply a downward driving force to the sliding part 21.

[0046] Preferably, the connecting end 222 is the junction of the extending portion 22 and the sliding portion 21 .

[0047] The extension portion 22 is in a plate shape as a whole 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 that of the second section 223 .

[0048] Since the width of the first section 221 is smaller than that of the second section 223, under the action of the same force, the first section 221 can produce a greater degree of deformation relative to the second section 223. When the user drives the sliding part 21, the extension part 22 can retract the movable end 224 more quickly, making it more convenient and quicker to unlock the container cover and the container body 7 from each other.

[0049] The movable end 224 is provided with an inclined surface 225 , which is inclined downward.

[0050] This avoids the occurrence of a blockage between the movable end 224 and the edge of the escape opening 6 during use, making the use smoother.

[0051] The number of the extending portions 22 is at least two, and the extending portions 22 are evenly distributed in the circumferential direction around the sliding portion 21 .

[0052] The extensions 22 are evenly distributed around the sliding portion 21 . When the sliding portion 21 is driven to move, the reaction of the extensions 22 on the sliding portion 21 is more even around the sliding portion 21 , thus preventing the sliding portion 21 from getting stuck due to uneven force during movement.

[0053] refer to Figure 7 , 8 The cover body 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 convex plate 121. When the notch 112 and the convex plate 121 are spliced ​​together, the avoidance opening 6 is formed between the end of the convex plate 121 and the bottom of the notch 112.

[0054] Since the sliding portion 21 and the extension portion 22 are two inseparable parts of the movable member 2, if each extension portion 22 is directly connected and inserted into the avoidance opening 6, the elastic limit requirement for the extension portion 22 is relatively high, and the assembly is difficult, which can easily cause the extension portion 22 to break directly during the assembly process; during the installation process of the container cover, each extension portion 22 is first aligned and placed in each notch 112, and then the convex plate 121 is connected and clamped with the notch 112 to complete the assembly of the extension portion 22 and the avoidance opening 6, which greatly reduces the difficulty of assembly, and there is no need to bend the extension portion 22, which will not cause accidental breakage of the extension portion 22.

[0055] The number of the notches 112 and the protruding plates 121 is equal to the number of the extending portions 22 .

[0056] refer to Figure 2 The sliding portion 21 is hollow inside and is in the shape of a vertically extending cylinder, with an open port formed at the lower portion of the sliding portion 21. A columnar portion 115 is provided inside the bottom cover 11, and the upper end of the columnar portion 115 extends into the sliding portion 21. During the use of the container cover, the columnar portion 115 always maintains sliding with the sliding portion 21.

[0057] The side wall of the notch 112 is provided with a strip-shaped depression 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 depression 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 correspondingly inserted into the strip-shaped depression 113.

[0058] After the bottom cover 11 and the splicing cover 12 are connected to each other, the ribs 122 and the strip-shaped recesses 113 are interlocked with each other, so that the edges of the convex plate 121 and the edges of the notch 112 are more stably spliced ​​with each other, avoiding relative misalignment between the convex plate 121 and the notch 112 in the inside-out direction.

[0059] refer to Figure 5 , 7 8. Preferably, the strip-shaped recesses 113 are arranged on the inner walls on both sides of all the notches 112 , and the convex ribs 122 are arranged on the opposite side walls of all the convex plates 121 .

[0060] The cover body 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 the sliding part 21. A limiting part 131 is extended outward along the edge of the top cover 13. A stopper 141 is provided on the fixed cover 14. When the limiting part 131 abuts against the stopper 141, the top cover 13 is at the maximum maximum height.

[0061] The volume of the top cover 13 is relatively large, and the user can drive the sliding part 21 to move by pressing the top cover 13 to make it more convenient to use. The stopper 141 has a limiting effect on the limiting part 131, which can prevent the top cover 13 from detaching alone.

[0062] refer to Figure 3 , 4 , 5, 7, 8, 9, a first vertical groove 123 is provided on the splicing cover 12, and a second vertical groove 116 and a transverse groove 117 are provided on the bottom cover 11, and the second vertical groove 116 and the transverse groove 117 are connected to each other; when the splicing cover 12 and the bottom cover 11 are connected, the first vertical groove 123 and the second vertical groove 116 are butted against each other, a limiting protrusion 111 is provided near the end of the transverse groove 117, and a locking protrusion 142 is correspondingly provided on the inner wall of the fixed cover 14.

[0063] During the assembly process, the locking protrusion 142 passes through the first vertical groove 123, the second vertical groove 116 and the transverse groove 117 in sequence, and finally the locking protrusion 142 is stuck between the end of the transverse groove 117 and the limiting protrusion 111. The fixed cover 14 can be operated in the reverse direction according to this path to make the fixed cover 14 detached from the bottom cover 11 and the splicing cover 12, and the disassembly and assembly of the fixed cover 14 is very convenient; the user can quickly disassemble the various components on the container cover and clean the inside, even remove water stains and tea stains inside the container cover, making it more hygienic to use.

[0064] The cover body 1 includes a retaining ring 15 , and the outer wall of the retaining ring 15 is in contact with the inner walls of the bottom cover 11 and the splicing cover 12 at the same time.

[0065] The connection between the edge of the notch 112 and the edge of the protruding plate 121 is more stable, avoiding mutual misalignment, and making the connection more stable.

[0066] A vent hole 114 is provided on the cover body 1, 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, and an elastic member 5 is provided between the limiting plate 31 and the cover body 1, and the upper surface of the limiting plate 31 abuts against the sliding part 21.

[0067] When the sliding part 21 slides downward, the movable rod 3 is driven to slide downward by pushing the limit plate 31, so that the sealing block 4 and the air vent 114 are separated from each other. It is very convenient to use. When the container cover is opened, the air pressure inside and outside the container is balanced through the air vent 114, which effectively reduces the difficulty of opening the container cover. After the downward pressure on the sliding part 21 disappears, the rebound force of the elastic member 5 can be transmitted to the sliding part 21 through the limit plate 31, and the auxiliary sliding part 21 returns to the initial position upward for repeated use.

[0068] The ventilation hole 114 is formed on the bottom cover 11 .

[0069] Preferably, in the initial state where the container cover is not subjected to external force, the top end of the movable rod 3 abuts against the top cover 13, and the user can release the sealing effect of the sealing block 4 on the air hole 114 while pressing down the top cover 13, and the air permeation action is very fast and convenient to use.

[0070] Preferably, the elastic member 5 is a spring sleeved on the movable rod 3 .

[0071] refer to Figure 1-Figure 12 The assembly process of the container cover of the present invention is as follows: the spring is sleeved on the movable rod 3, and the bottom end of the movable rod 3 passes through the air vent 114 and is connected to the sealing block 4; secondly, each extension portion 22 is aligned and placed in the notch 112 to realize that the movable part 2 is placed in the bottom cover 11 as a whole; then, the convex plate 121 is aligned with the notch 112 and fits with each other, and in this process, the convex rib 122 is aligned and inserted into the strip-shaped recess 113; then, the retaining ring 15 is placed in the bottom cover 11 and the splicing cover 12, so that the retaining ring 15 fits on the inner side walls 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 through the first vertical groove 123, the second vertical groove 116 and the transverse groove 117 in sequence, and finally the locking protrusion 142 is stuck between the end of the transverse groove 117 and the limiting protrusion 111.

[0072] When in use, the user presses down the top cover 13, pushing the sliding part 21 to slide downward, and the extending part 22 as a whole produces elastic deformation, the connecting end 222 gradually moves away from the avoidance opening 6, and the movable end 224 is driven to retract inward toward the avoidance opening 6 until it is locked with the container body 7; in this process, the top cover 13 moving downward pushes the movable rod 3, so that the sealing block 4 is separated from the air vent 114 to achieve balanced adjustment of the air pressure inside and outside the container body.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
