Description

Technical Field

[0001] The present invention relates to the field of drinking water containers, and particularly to an elastic and deformable screwless container cover.

Background Art

[0002] Currently, cups and pots have become essential drinking utensils carried around by many people as daily necessities. However, in the market, screw-on covers are commonly seen. When users use them, they need to hold the container with one hand and the container cover with the other hand, and rotate the two relatively to open them. Usually, it is necessary to rotate the container cover multiple times relative to the container, which is very inconvenient to use. Therefore, many screwless container covers, such as the electrically unlockable container cover and container with application number CN202410044096.5, have appeared on the market. The locking members for engaging with the cup body are provided independently of each other, and the number is set to be plural. Generally speaking, there are many parts inside the container cover, making its production and assembly difficult. Moreover, after the container cover is produced, the inner cover body and the outer cover body cannot be removed from each other. Compared with the container cover in the patent, when used for a long time, scale and tea stains will enter the inside of the container cover from the gap between the through holes and the locking members, generating bacteria and bad odors, which have an adverse impact on hygiene and the use experience.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In order to solve the above problems, the present invention proposes an elastic and deformable screwless container cover, which solves the problems that the container cover has many members, is difficult to assemble, and cannot be separated and washed.

Means for Solving the Problems

[0004] The technical solution adopted by the present invention is as follows. It is an elastic deformable screwless container cover, including a cover body and a movable member. The movable member includes a sliding part and an extension part. The cover body is provided with a relief opening for the extension part to pass through. The extension part has the ability of elastic deformation. Both ends of the extension part are a movable end and a connection end respectively. The movable end is closer to the relief opening than the connection end. When the sliding part is driven to gradually separate the connection end from the relief opening, the movable end contracts towards the relief opening.

[0005] According to the above technical solution, the movable member includes a sliding part and an extension part connected to each other. The extension part is used to engage with the opening of the container body. Attaching the entire movable member to a predetermined position at one time is equivalent to attaching several extension parts to the predetermined position simultaneously. The number of members in the container cover is reduced, and the assembly of the container cover becomes easier. When the user drives the sliding part to slide the connection hole, the extension part elastically deforms, whereby the movable end can be retracted to release the engagement with the container body, and the use is very convenient.

[0006] Furthermore, the extension part is provided in a plate shape as a whole. The extension part includes a first segment and a second segment formed integrally. The first segment is connected to the connection end, and the second segment is connected to the movable end. The width of the first segment is smaller than the width of the second segment.

[0007] According to the above technical solution, since the width of the first segment is smaller than that of the second segment, when receiving the same force, the first segment can cause a greater deformation compared to the second segment. When the user drives the sliding part, the extension part can retract the movable end more quickly, and the unlocking of the container cover and the container body can be realized more conveniently and quickly.

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

[0009] According to the above technical solution, during use, the relative blocking between the movable end and the edge of the escape opening is avoided, making the use smoother.

[0010] Furthermore, the number of the extension parts is at least two, and the extension parts are uniformly distributed circumferentially around the sliding part.

[0011] According to the above technical solution, each extension part is uniformly distributed circumferentially with respect to the sliding part. When moving the sliding part, the reaction of each extension part on the sliding part becomes more uniform in the circumferential direction, avoiding the sliding part from sticking due to receiving non-uniform forces during movement.

[0012] Furthermore, the cover body includes a bottom cover and a joint cover. A notch is provided on the bottom cover, and a convex plate is provided on the joint cover. When the notch and the convex plate are joined, the escape opening is formed between the end of the convex plate and the bottom of the notch.

[0013] According to the above technical solution, since the sliding part and the extension part are two parts that cannot be separated from the movable member, if each extension part is directly butted and inserted into the escape opening, the requirement for the elastic limit of the extension part is high, and the assembly is difficult, and it is easy to directly cause the breakage of the extension part during the assembly process. In the process of installing the container cover, first, each extension part is aligned and arranged in each notch, and then the convex plate is butted and engaged with the notch, thereby completing the assembly of the extension part and the escape opening. The difficulty of assembly is greatly reduced, there is no need to bend the extension part, and the extension part will not break unexpectedly.

[0014] Furthermore, a strip-shaped recess is provided on the side wall of the notch, and a convex rib is provided on the side wall of the convex plate, or a strip-shaped recess is provided on the side wall of the convex plate, and a convex rib is provided on the side wall of the notch. During the joining process of the notch and the convex plate, the convex rib is correspondingly inserted into the strip-shaped recess.

[0015] According to the above technical solution, after the bottom cover and the joint cover are connected to each other, the convex rib and the strip-shaped concave portion are fitted to each other, and the joint between the edge of the convex plate and the edge of the notch is more stable, and the relative displacement of the convex plate and the notch in the inner and outer directions is avoided.

[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 press the sliding portion. A limiting portion is provided to extend outward at the edge of the top cover. A stopper is provided on the fixed cover. When the limiting portion abuts against the stopper, the top cover is located at the maximum height.

[0017] According to the above technical solution, the volume of the top cover is large, and the user can displace the sliding portion by pressing the top cover, making the use more convenient. The stopper has a limiting effect on the limiting portion and can prevent the top cover from being separated alone.

[0018] Furthermore, a first longitudinal groove is provided on the joint cover, and a second longitudinal groove and a transverse groove that communicate with each other are provided on the bottom cover. When the joint cover and the bottom cover are connected, the first longitudinal groove and the second longitudinal 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] According to the above technical solution, in the process of assembly, the locking protrusion passes through the first longitudinal groove, the second longitudinal groove and the transverse groove in sequence. Finally, the locking protrusion is locked between the end of the transverse groove and the limiting protrusion. Operating the fixed cover in the reverse direction along this path can separate the fixed cover from the bottom cover and the joint cover, making the attachment and detachment of the fixed cover very convenient. The user can quickly remove each member of the container cover and clean its interior, and can timely remove the scale and tea stains inside the container cover, making the use more hygienic.

[0020] Furthermore, the cover body includes a retaining ring, and the outer wall of the retaining ring is in close contact with the inner walls of the bottom cover and the joint cover simultaneously.

[0021] According to the above technical solution, the connection between the edge of the notch and the edge of the convex plate is more stable, mutual displacement is avoided, and the connection stability is higher.

[0022] Furthermore, ventilation holes are provided in the cover body, a movable rod is movably provided in the ventilation holes, a sealing block for closing the ventilation holes is provided at 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 is in contact with the sliding portion.

[0023] According to the above technical solution, when the sliding portion slides downward, the movable rod is slid downward by pressing the limiting plate, thereby realizing the separation of the sealing block from the ventilation holes. The use is very convenient. At the same time as opening the container cover, the air pressure inside and outside the container is balanced through the ventilation holes, and the difficulty of opening the container cover is effectively reduced. After the downward pressure on the sliding portion disappears, the repulsive force of the elastic member can be transmitted to the sliding portion through the limiting plate, assisting the sliding portion to return to the initial position upward and enabling reuse.

Thus, the features limited by "first" and "second" may explicitly or implicitly include at least one such feature. Also, the technical solutions between the respective embodiments can be combined with each other, but it must be based on what can be achieved by those skilled in the art.

[0029] As shown in FIGS. 1 to 6, it is an elastic deformable screwless container cover, including a cover body 1 and a movable member 2. The movable member 2 includes a sliding portion 21 and an extension portion 22. The cover body 1 is provided with a relief opening 6 for the extension portion 22 to pass through. The extension portion 22 has the ability of elastic deformation. Both ends of the extension portion 22 are a movable end 224 and a connection end 222 respectively. The movable end 224 is closer to the relief opening 6 than the connection end 222. When driving the sliding portion 21 to gradually separate the connection end 222 from the relief opening 6, the movable end 224 contracts toward the relief opening 6.

[0030] The movable member 2 includes a sliding portion 21 and an extension portion 22 that are connected to each other. The extension portion 22 is used to engage with the opening of the container body. Mounting the entire movable member 2 at a predetermined position at once is equivalent to simultaneously mounting several extension portions 22 at the predetermined position. The number of members inside the container cover is reduced, and the assembly of the container cover becomes easier. By the user driving the sliding portion 21 to slide the connection hole, the extension portion 22 elastically deforms, whereby the movable end 224 can be retracted and disengaged from the engagement with the container body, and the use is very convenient.

[0031] According to the specific shape design of the movable member 2, the relative positional relationship between the connection end 222 and the movable end 224 in the initial state where the movable member 2 is not subjected to an external force has the following three forms that can be selected by the designer. 1. The height of the connection end 222 is lower than the height of the movable end 224. When the sliding portion 21 is moved downward, the connection end 222 can be gradually moved away from the escape port 6, thereby realizing the purpose of retracting the movable end 224. 2. The height of the connection end 222 is equal to the height of the movable end 224. When the sliding portion 21 is moved upward or downward, the connection end 222 can be gradually moved away from the escape port 6, thereby realizing the purpose of retracting the movable end 224. 3. The height of the connection end 222 is higher than the height of the movable end 224. When the sliding portion 21 is moved downward, the connection end 222 can be gradually moved away from the escape port 6, thereby realizing the purpose of retracting the movable end 224. In the present invention, preferably, the height of the connection end 222 is lower than the height of the movable end 224. In order to realize the purpose of retracting the movable end 224 toward the escape port 6, the user needs to apply a downward driving force to the sliding portion 21.

[0032] Preferably, the connection end 222 is the joint portion between the extension portion 22 and the sliding portion 21.

[0033] The extension portion 22 is provided in a plate shape as a whole, and the extension portion 22 includes a first segment 221 and a second segment 223 formed integrally. The first segment 221 is connected to the connection end 222, the second segment 223 is connected to the movable end 224, and the width of the first segment 221 is smaller than the width of the second segment 223.

[0034] Compared with the second segment 223, since the width of the first segment 221 is smaller, when receiving the same force, the first segment 221 can cause a greater deformation with respect to the second segment 223. When the user drives the sliding portion 21, the extension portion 22 can retract the movable end 224 more quickly, and the unlocking of the container cover and the container body can be realized more conveniently and quickly.

[0035] The movable end 224 is provided with an inclined surface 225 that slopes downward.

[0036] This avoids the relative blocking between the movable end 224 and the edge of the relief opening 6 during use, making the use smoother.

[0037] The number of the extension parts 22 is at least two, and the extension parts 22 are evenly distributed in the circumferential direction around the sliding part 21.

[0038] Each extension part 22 is evenly distributed in the circumferential direction with respect to the sliding part 21. When moving the sliding part 21, the reaction of each extension part 22 with respect to the sliding part 21 becomes more uniform in the circumferential direction, avoiding the sliding part 21 from sticking due to receiving non-uniform forces during movement.

[0039] As shown in FIGS. 7 and 8, the cover body 1 includes a bottom cover 11 and a joint cover 12. The bottom cover 11 is provided with a notch 112, and the joint cover 12 is provided with a convex plate 121. When the notch 112 and the convex plate 121 are joined, the relief opening 6 is formed between the end of the convex plate 121 and the bottom of the notch 112.

[0040] Since the sliding part 21 and the extension parts 22 are two inseparable parts of the movable member 2, if each extension part 22 is directly butted and inserted into the relief opening 6, the requirements for the elastic limit of the extension parts 22 are high, and the assembly is difficult, and it is easy to directly cause the breakage of the extension parts 22 during the assembly process. In the process of installing the container cover, first, each extension part 22 is aligned and arranged in each notch 112, and then the convex plate 121 is butted against the notch 112 for engagement, thereby completing the assembly of the extension parts 22 and the relief opening 6. The difficulty of assembly is greatly reduced, and it is no longer necessary to bend the extension parts 22, and the extension parts 22 will not break unexpectedly.

[0041] The number of the notches 112 and the convex plates 121 is the same as the number of the extension parts 22.

[0042] As shown in Fig. 2, the sliding part 21 is hollow inside, and the sliding part 21 forms a cylindrical shape extending in the vertical direction. The lower part of the sliding part 21 forms an open port, and a columnar part 115 is provided in the bottom cover 11. 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.

[0043] A strip-shaped recess 113 is provided on the side wall of the notch 112, a convex rib 122 is provided on the side wall of the convex plate 121, or a strip-shaped recess 113 is provided on the side wall of the convex plate 121, and a convex rib 122 is provided on the side wall of the notch 112. During the joining process of the notch 112 and the convex plate 121, the convex rib 122 is correspondingly inserted into the strip-shaped recess 113.

[0044] After the bottom cover 11 and the joining cover 12 are connected to each other, the convex rib 122 and the strip-shaped recess 113 are fitted to each other, and the mutual joining of the edge of the convex plate 121 and the edge of the notch 112 is more stable, and the relative displacement of the convex plate 121 and the notch 112 in the inner and outer directions is avoided.

[0045] As shown in Figs. 5, 7, and 8, preferably, the strip-shaped recesses 113 are provided on the inner walls on both sides of all the notches 112, and the convex ribs 122 are provided on the opposite side walls of all the convex plates 121.

[0046] 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 press the sliding part 21. A limiting part 131 extends outwardly at the edge of the top cover 13, and 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 located at the maximum height.

[0047] The volume of the top cover 13 is large. The user can displace the sliding part 21 by pressing the top cover 13, making the use more convenient. The stopper 141 has a limiting effect on the limiting part 131 and can prevent the top cover 13 from being separated alone.

[0048] As shown in FIGS. 3, 4, 5, 7, 8, and 9, a first longitudinal groove 123 is provided in the joint cover 12, and second longitudinal grooves 116 and a transverse groove 117 that communicate with each other are provided in the bottom cover 11. When the joint cover 12 and the bottom cover 11 are connected, the first longitudinal groove 123 and the second longitudinal groove 116 abut 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.

[0049] In the process of assembly, the locking protrusion 142 passes through the first longitudinal groove 123, the second longitudinal groove 116, and the transverse groove 117 in sequence. Finally, the locking protrusion 142 is locked between the end of the transverse groove 117 and the limiting protrusion 111. When the fixed cover 14 is operated in the reverse direction along this path, the fixed cover 14 can be separated from the bottom cover 11 and the joint cover 12, making the attachment and detachment of the fixed cover 14 very convenient. The user can quickly remove each member of the container cover and clean its interior, timely remove scale and tea stains inside the container cover, and make the use more hygienic.

[0050] The cover body 1 includes a retaining ring 15, and the outer wall of the retaining ring 15 is in close contact with the inner walls of the bottom cover 11 and the joint cover 12 at the same time.

[0051] The connection between the edge of the notch 112 and the edge of the convex plate 121 is more stable, mutual displacement is avoided, and the connection stability is higher.

[0052] The cover body 1 is provided with a ventilation hole 114, a movable rod 3 is movably provided in the ventilation hole 114, a sealing block 4 for closing the ventilation hole 114 is provided at the bottom end of the movable rod 3, a limiting plate 31 is provided on the movable rod 3, 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 is in contact with the sliding portion 21.

[0053] When the sliding part 21 is slid downward, the movable rod 3 is slid downward by pressing the limiting plate 31, thereby realizing the separation of the sealing block 4 and the ventilation hole 114. The use is very convenient. At the same time as the container cover is opened, the air pressure inside and outside the container is balanced through the ventilation hole 114, and the difficulty of opening the container cover is effectively reduced. After the downward pressure on the sliding part 21 disappears, the repulsive force of the elastic member 5 can be transmitted to the sliding part 21 through the limiting plate 31, assisting the sliding part 21 to return upward to the initial position and enabling reuse.

[0054] The ventilation hole 114 is opened in the bottom cover 11.

[0055] Preferably, in the initial state where the container cover is not subjected to an external force, the top of the movable rod 3 abuts against the top cover 13. When the user presses down the top cover 13, the sealing action of the sealing block 4 on the ventilation hole 114 can be released at the same time, and the ventilation operation is very fast and the use is convenient.

[0056] Preferably, the elastic member 5 is a spring externally fitted on the movable rod 3.

[0057] As shown in FIGS. 1 to 10, the assembly process of the container cover of the present invention is as follows. The spring is externally installed on the movable rod 3. The bottom end of the movable rod 3 is connected to the sealing block 4 after passing through the ventilation hole 114. Next, by aligning each extension part 22 and arranging it in the notch 112, the movable member 2 is arranged in the bottom cover 11 as a whole. Next, the convex plate 121 is aligned with the notch 112 and fitted with each other. In this process, the convex rib 122 is aligned with the strip-shaped concave part 113 and inserted. Next, the retaining ring 15 is arranged on the bottom cover 11 and the joint cover 12 so that the retaining ring 15 is in close contact with the inner walls of the bottom cover 11 and the joint cover 12. Finally, the top cover 13 is overlapped on the sliding part 21, and the fixing cover 14 is operated so that the locking protrusion 142 passes through the first vertical groove 123, the second vertical groove 116, and the horizontal groove 117 in sequence. Finally, the locking protrusion 142 is locked between the end of the horizontal groove 117 and the limiting protrusion 111.

[0058] When in use, when the user presses down the top cover 13 and presses the sliding part 21 to slide downward, the extension part 22 is elastically deformed as a whole, the connection end 222 gradually moves away from the escape port 6, and the movable end 224 is driven to retract toward the escape port 6 until it is locked to the container body. The container body is used in conjunction with the container. Since it is a common technique to realize locking and separation from the container body by changing the position of the movable end 224, it will not be repeatedly described here. In this process, the top cover 13 moving downward presses the movable rod 3, and the sealing block 4 separates from the vent hole 114, realizing the equalization and adjustment of the air pressure inside and outside the container body.

[0059] The above content is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Under the inventive concept of the present invention, equivalent structural conversions made using the content of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields are included within the patent protection scope of the present invention.
