Description

Technical Field

[0001] This invention relates to the field of accessories for handheld cutting equipment, specifically to a container lid and a container. Background Technology

[0002] With the development of mechanization, handheld cutting equipment has been widely used due to its ease of use. Existing handheld cutting equipment, such as chainsaws, includes a motor, a saw chain, and an oil reservoir. The motor drives the saw chain to cut. The oil reservoir stores lubricating oil for lubricating the saw chain. The oil reservoir is usually equipped with a lid, which seals the opening of the reservoir to allow for opening or closing of the oil reservoir chamber for oil replacement or replenishment. Currently, the lid is usually threaded onto the opening of the oil reservoir and is manually tightened. However, because the tightening force varies from person to person, the tightness of the lid is inconsistent. A weak tightening force often results in an incomplete seal, while a strong tightening force often leads to over-tightening. Combined with the adhesion of the lubricating oil, this makes reopening difficult. Therefore, a lid and container are needed to improve these problems. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a container lid and a container to improve the problem that the existing container lids need to be rotated and tightened, and the torque cannot be accurately controlled.

[0004] To achieve the above and other related objectives, the present invention provides a container lid for installation on an opening of a container body. The container lid includes a lid body, a core, and an operating body. The lid body is disposed on the opening and seals the opening. The core is slidably mounted on the lid body. The operating body is movably mounted on the lid body and has a first position and a second position. When the operating body is in the first position, the lid body is locked and seals the opening. When the operating body is in the second position, the lid body is unlocked from the opening.

[0005] In one example of the present invention, the cover body includes a first through hole and an elastic claw disposed around the first through hole, and the cover body is configured to be able to be engaged with the opening by means of the elastic claw and to form a sealing fit between the opening and the opening.

[0006] In one example of the present invention, the container lid also includes an elastomer disposed between the core and the lid body, which stores or releases energy during the sliding of the core.

[0007] In one example of the present invention, the operating body is rotatably mounted on the cover body and reciprocates between a first position and a second position to compress the core to reciprocate within the first through hole.

[0008] In one example of the present invention, a limiting structure is provided between the operating body and the core to limit the operating body to a first position and / or a second position.

[0009] In one example of the present invention, the limiting structure includes a curved protrusion and a groove that matches the curved protrusion. The curved protrusion is disposed on one of the core and the operating body, and the groove is disposed on the other between the core and the operating body.

[0010] In one example of the present invention, a first mounting base is provided on the side of the cover body away from the container body, and the two sides of the operating body are rotatably connected to the first mounting base.

[0011] In one example of the present invention, a second mounting seat is provided on the side of the cover body away from the container body. The second mounting seat is located inside the first mounting seat. Connecting seats are provided on both sides of the operating body. The connecting seats on both sides are located between the second mounting seat and the first mounting seat on both sides, and are rotatably connected by a rotating shaft.

[0012] In one example of the present invention, the elastic claw includes a protrusion disposed on the outer side of the elastic claw. When the operating body is in the first position, the core body squeezes the elastic claw under the action of the elastic body to lock the elastic claw. The mating surface between the elastic claw and the opening is a first frustum surface, and the small end of the first frustum surface faces the direction in which the cover body moves out of the opening.

[0013] In one example of the present invention, the opening is circular, the sidewall shape of the cover body matches the opening, and the cover body is provided with multiple elastic claws along the circumference, with positioning elements provided between adjacent elastic claws.

[0014] In one example of the present invention, the container cap further includes a first sealing element, which is sleeved on the outside of the elastic claw and disposed between the cap body and the opening. The mating surface between the first sealing element and the opening is a second frustum surface, with the small end of the second frustum surface facing the side of the elastic claw.

[0015] In one example of the present invention, a first limiting platform is provided on the cover body, a second limiting platform is provided on the core body, an elastic body is fitted around the outer periphery of the core body, and the two ends of the elastic body abut against the first limiting platform and the second limiting platform respectively.

[0016] In one example of the present invention, the core includes a first structure and a second structure, the first structure and the second structure are detachably connected, the end of the first structure away from the second structure abuts against the operating body, the second structure includes a support for locking the elastic claw, the mating surface of the support and the elastic claw is a third frustum surface, the small end of the third frustum surface faces the direction in which the cover body moves out of the opening.

[0017] In one example of the present invention, a one-way valve is provided in the second structure. The air inlet of the one-way valve is connected to the external environment, and the air outlet of the one-way valve is connected to the inner cavity of the container body.

[0018] In one example of the present invention, the second structure further includes a main body portion, which is slidably engaged with the first through hole, and a support portion is connected to the outer periphery of the main body portion.

[0019] In one example of the present invention, the main body is provided with a second through hole along the axial direction, and a third limiting platform protruding towards the center is provided inside the second through hole. The one-way valve is installed in the second through hole, and the flange of the one-way valve abuts against the third limiting platform. The first structure is connected to the second structure and presses the flange onto the third limiting platform.

[0020] In one example of the present invention, the first structure and the second structure are threaded together, and a gasket for protecting the one-way valve is provided between the one-way valve and the first structure.

[0021] In one example of the present invention, a second sealing element is provided at the connection between the support part and the main body. When the operating body is in the first position, the second sealing element is sealed between the second structure and the cover body. The mating surface between the second sealing element and the cover body is a fourth frustum surface, and the small end of the fourth frustum surface faces the direction in which the cover body moves out of the opening.

[0022] In one example of the present invention, the operating body is slidably mounted on the cover body and reciprocates linearly between a first position and a second position to compress the core to reciprocate within the first through hole.

[0023] The present invention also provides a container having an opening on its body and a container lid installed on the opening. The container lid includes a lid body and a core operating body. The lid body includes a core disposed on the opening and sealing the opening; a core slidably mounted on the lid body; and an operating body movably mounted on the lid body and having a first position and a second position. When the operating body is in the first position, the lid body is locked and seals the opening. When the operating body is in the second position, the lid body is unlocked from the opening.

[0024] In summary, the container lid of this invention has a core that is slidably mounted on the lid body and controlled by an operating body that is movably mounted on the lid body. When the operating body is in the first position, the core seals the opening; when the operating body is in the second position, the lid body unlocks from the opening, allowing the lid body to detach from the opening. This design achieves locking and separation of the container lid and the container body through the sliding of the core, changing the existing method of locking the container lid by rotating it. When the operating body is in the first position, the container lid and the container body are locked; when the operating body is in the second position, the container lid and the container body are unlocked. No screwing operation is required during opening or closing, improving the problem of inconsistent tightening of the container lid due to different manual tightening forces. It also improves the problem of the container lid getting stuck and difficult to open due to excessive tightening and the adhesion of lubricating oil. In addition, the container lid changes the form of rotation locking by threads, breaking the limitation that the outer contour of the container lid must be circular. Attached Figure Description

[0046] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in the present invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of the invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to the methods, devices, and materials in the embodiments of the present invention.

[0047] In view of the shortcomings in the above background technology, the purpose of the present invention is to provide a container lid and a container to improve the problem that the torque cannot be accurately controlled when the prior art requires rotation and tightening.

[0048] Please see Figures 1 to 16 The container 10 includes a container body 200 and a container cap 100. The container body 200 has a liquid storage chamber with an opening 210. The container cap 100 is detachably mounted on the opening 210.

[0049] Please see Figures 5 to 15 The container lid 100 includes a lid body 110, a core 120, and an operating body 140. It changes the existing technology of locking the container lid 100 by rotating it, and improves the problem of inconsistent tightening state of the container lid 100 caused by different manual tightening forces.

[0050] The cover body 110 is disposed on the opening 210 and seals the opening 210. The cross-sectional shape of the outer contour of the cover body 110 is not limited. For example, it can be a circle, square, polygon or other irregular closed shape. The outer contour of the cover body 110 corresponds to the shape of the opening 210 and can seal the opening 210. There are various sealing methods for the cover body 110 and the opening 210, including mechanical seal, rubber seal, coating seal or pre-tightening seal, etc., but not limited to the above.

[0051] The core 120 is slidably mounted on the cover body 110. The shape of the mating position of the core 120 and the cover body 110 is not limited. It can be cylindrical, cuboid, polygonal prism, etc., as long as it can enable sliding between the core 120 and the cover body 110.

[0052] Please see Figure 5 , Figure 6 , Figure 8 and Figures 10 to 11 The operating body 140 is movably mounted on the cover body 110. The movable mounting method can be varied, including rotational mounting (e.g., hinged mounting) or sliding mounting (e.g., a button slidingly connected to the cover body 110). No limitation is made here, as long as it allows the control core 120 to slide on the cover body 110. The operating body 140 has a first position and a second position. Figure 6 This is a cross-sectional schematic diagram of the operating body in the container lid of the present invention when it is in the first position. Figure 8 This is a cross-sectional view of the operating body 140 in the container lid of the present invention when it is in the second position. When the operating body 140 is in the first position, the lid body 110 is locked and seals the opening 210. When the operating body 140 is in the second position, the lid body 110 is unlocked from the opening 210, allowing the lid body 110 to detach from the opening 210. It should be noted that the locking described above refers to the locking between the lid body 110 and the container body 200 along the relative disengagement direction (e.g., ...). Figure 2 The locking mechanism is fixed relative to the container body 200 in the X direction. The locking method is not limited, such as elastic claws, interference fit, etc.; unlocking means that the cover body 110 is allowed to move out relative to the container body 200 in the X direction.

[0053] In the above example, the locking and unlocking of the container lid 100 and the container body 200 is achieved by the up-and-down movement of the core 120, which changes the existing method of locking the container lid 100 by rotating it. When the operating body 140 is in the first position, the container lid 100 and the container body 200 are locked; when the operating body 140 is in the second position, the container lid 100 and the container body 200 are unlocked. This improves the problem of inconsistent tightening of the container lid 100 due to different manual tightening forces. The locking force between the container lid 100 and the container body 200 can be controlled by the structure and size of the container lid 100 or the elasticity of the elastic body 130, which can improve the problem of the container lid 100 getting stuck and difficult to open due to excessive tightening and the adhesion of lubricating oil. In addition, the container lid 100 changes the form of rotation locking by threads, breaking the limitation that the outer contour of the container lid 100 must be circular.

[0054] In one example of the container lid of the present invention, please refer to Figure 2 , Figure 6 , Figure 8 , Figure 10 , Figures 12 to 13 The cap body 110 includes a first through hole 111 and an elastic claw 112 surrounding the first through hole 111. The cap body 110 is configured to be able to engage with the opening 210 of the container body 200 via the elastic claw 112 and to form a sealing fit with the opening 210. The cross-sectional shape of the outer contour of the cap body 110 is not limited; for example, it can be a circle, square, polygon, or other irregular closed shape. The outer contour of the cap body 110 corresponds to the shape of the opening 210 and can seal the opening 210. There are various sealing methods between the cap body 110 and the opening 210, including mechanical seals, rubber seals, coating seals, or pre-tightening seals, but not limited to the above.

[0055] Further, please refer to Figure 2 , Figure 6 , Figure 8 , Figure 10 , Figures 14 to 15 The core 120 is slidably installed within the first through hole 111. The shape of the mating position between the core 120 and the first through hole 111 is not limited; it can be cylindrical, cuboid, polygonal, etc., as long as the core 120 can slide within the first through hole 111. Specifically, in this embodiment, the mating position between the core 120 and the first through hole 111 is cylindrical, and the first through hole 111 is a cylindrical through hole. The core 120 is slidably inserted into the first through hole 111 and can move linearly back and forth along the axial direction. The elastic claw 112 is configured to deform under the action of the core 120 to engage with the opening 210, thus locking the container lid 100. The number and form of the elastic claw 112 are not limited; there can be one or more. The elastic claw 112 only needs to be deformable and have an engaging structure.

[0056] In one example of the container lid of the present invention, the container lid 100 further includes an elastic body 130. The elastic body 130 is disposed between the core 120 and the lid body 110, and stores or releases energy during the sliding of the core 120. The elastic body can be a spring, disc spring, rubber or other structural components that can store and release energy. The elastic body acts between the core 120 and the lid body 110 to achieve deformation of the elastic claw 112 through the core 120, and to lock the lid body 110 and the container body 200 through the locking structure.

[0057] Please see Figure 6 , Figure 8 and Figures 10 to 11In one example of the present invention, the operating body 140 is rotatably mounted on the cover body 110 and reciprocates between a first position and a second position to compress the core 120 to reciprocate within the first through hole 111. Specifically, the operating body 140 and the cover body 110 are rotatably connected by a rotating shaft 142. The rotating shaft 142 can be an independent component that passes through and connects the operating body 140 and the cover body 110. The rotating shaft 142 can also be integrally formed with the operating body 140, and a through hole or blind hole rotatably connected to the rotating shaft 142 is provided on the cover body 110. Similarly, the rotating shaft 142 can also be integrally formed with the cover body 110, and a through hole or blind hole rotatably connected to the rotating shaft 142 is provided on the operating body 140. Preferably, the operating body 140 also includes a holding part 141 to control the rotation of the operating body 140 with the cover body 110 via the rotating shaft 142, so as to realize the switching of the operating body 140 between the first position and the second position.

[0058] In one example of the present invention, please refer to Figure 5 and Figure 11 The rotating shaft 142 is an independent component, installed on the cover body 110 and perpendicular to the first through hole 111. A first mounting seat 113 is provided on the side of the cover body 110 away from the container body 200. The two ends of the rotating shaft 142 are rotatably connected to the first mounting seat 113. The operating body 140 is rotatably connected to the first mounting seat 113 through the rotating shaft 142. It should be further noted that the structure and shape of the first mounting seat 113 can be various, such as two oppositely arranged protrusions rotatably connected to the rotating shaft 142. In this embodiment, the first mounting seat 113 is a protrusion with a cross-section close to a semi-circular shape, and opposite support members are provided at both ends located at the diameter of the semi-circular protrusion. The support members are rotatably connected to the rotating shaft 142 and provide support for the rotating shaft 142. This structure improves the strength of the cover body 110 and makes the container cover 100 more aesthetically pleasing.

[0059] Furthermore, while achieving high strength and aesthetics in the cover body 110, a hollow structure 1131 is provided on the first mounting base 113 to ensure its lightweight nature. Please refer to [link / reference needed]. Figure 5 The shape, number, and position of the hollow structure 1131 are not limited. It can be formed in any shape of hole or groove at any position of the first mounting base 113. In this embodiment, the hollow structure 1131 is two fan-shaped grooves. The two fan-shaped grooves are spaced apart on the outside of the semi-circular protrusion of the first mounting base 113, which can achieve the effect of reducing the weight of the cover body 110.

[0060] Please see Figure 11 and Figure 12In one example of the present invention, along the axial direction of the rotation axis 142, a second mounting seat 114 is also provided on the side of the cover body 110 away from the container body 200. The second mounting seat 114 is located inside the first mounting seat 113, and there is a gap between the second mounting seat 114 and the first mounting seat 113. Connecting seats 145 are respectively provided on both sides of the operating body 140. The connecting seats 145 on both sides are respectively located in the gap between the second mounting seat 114 and the first mounting seat 113 on both sides, and are rotatably connected through the rotation axis 142. This arrangement improves the strength of the operating body 140, which is beneficial to improving the service life of the operating body 140 as a component with high usage frequency.

[0061] Please see Figure 6 , Figure 8 and Figures 10 to 11 In one example of the present invention, considering that during the operation of the container 10, the locked state of the lid body 110 and the container body 200 needs to be maintained, and the lid body 110 and the container body 200 also need to be kept detached when the container lid 100 is removed from the container body 200, in order to achieve the above objectives, a limiting structure is provided between the operating body 140 and the core 120 to limit the operating body 140 to a first position and / or a second position. This limiting structure not only enables locking and detachment to be maintained, but also improves the reliability of locking and detachment of the lid body 110 and the container body 200. In addition, the operating body 140 can be accurately positioned to the first position and the second position respectively, which improves the problem of inconsistent tightening state of the container lid 100 due to different manual tightening forces.

[0062] There are various forms of limiting structures. In one example of the present invention, the limiting structure includes a curved protrusion 121 and a groove that matches the curved protrusion 121. For example, the curved protrusion 121 can be disposed on the core 120 and the groove can be disposed on the operating body 140. Alternatively, the curved protrusion 121 can be disposed on the operating body 140 and the groove can be disposed on the core 120. In this embodiment, please refer to [reference needed]. Figure 6 , Figure 8 and Figure 11The operating body 140 is provided with a first groove 143 and a second groove 144. The core 120 has a curved protrusion 121 protruding towards the operating body 140 at one end near the operating body 140. The curved protrusion 121 is adapted to fit the first groove 143 and the second groove 144. When the operating body 140 is in the first position, the first groove 143 abuts against the curved protrusion 121, thus confining the operating body 140 to the first position. When the operating body 140 is in the second position, the second groove 144 abuts against the curved protrusion 121, thus confining the operating body 140 to the second position. In this embodiment, in the height direction of the container 10, the height of the core 120 in the first position is higher than its height in the second position. In other embodiments, the height of the core 120 in the first position may also be lower than its height in the second position.

[0063] Please see Figure 2 , Figures 6 to 9 and Figures 12 to 13 In one example of the present invention, the elastic claw 112 includes a protrusion 1121, which is configured as a snap-fit ​​structure for the elastic claw 112. The protrusion 1121 is located on the outer side of the elastic claw 112. When the operating body 140 is in the first position, the core body 120 is pulled upward by the elastic body 130, and the lower end of the wall of the opening 210 contacts and squeezes the elastic claw 112 to lock the elastic claw 112. Preferably, the mating surface between the elastic claw 112 and the opening 210 is a first frustum surface 1122, with the small end of the first frustum surface 1122 facing the direction in which the cover body 110 moves out of the opening 210. Setting the mating surface to a frustum shape increases the contact area between the elastic claw 112 and the opening 210 and improves the sealing effect.

[0064] Please see Figures 2 to 4 , Figures 6 to 9 and Figures 12 to 13 In one example of the present invention, the opening 210 is circular, and the sidewall shape of the cover body 110 matches the opening 210 and is also circular. Along the circumference of the cover body 110, the cover body 110 is provided with a plurality of elastic claws 112. In this embodiment, four are evenly distributed. A positioning member 115 is provided between every two adjacent elastic claws 112. The positioning member 115 is also evenly distributed along the circumference of the cover body 110. Preferably, the positioning member 115 and the elastic claws 112 are partially connected. The connection part 1151 is preferably the end away from the protrusion. The positioning member 115 has the effect of improving the strength of the cover body 110 on the one hand, and on the other hand, it can play the role of positioning the core 120 to avoid the elastic claws 112 being damaged prematurely due to excessive force applied by the support part 1241 to the elastic claws 112.

[0065] Please see Figures 2 to 3 , Figure 6, Figure 8 and Figure 10 In one example of the present invention, the container cap 100 further includes a first sealing element 150. The first sealing element 150 is sleeved on the outside of the elastic claw 112 and is disposed between the cap body 110 and the opening 210. When the container cap 100 is locked with the container body 200, the first sealing element 150 is clamped by the opening 210 and the cap body 110 to achieve a sealing effect on the container 10. The material of the first sealing element 150 can be EPDM rubber, fluorosilicone rubber, or fluororubber, etc., but is not limited to these. The first sealing element 150 is preferably set as a closed annular gasket 126. Preferably, in this embodiment, please refer to Figure 3 The first sealing element 150 is disposed at the connection portion 1151 between the positioning element 115 and the elastic claw 112. This connection portion 1151 is a closed circle, which allows the first sealing element 150 to be subjected to uniform compressive force in the circumferential direction, thereby improving its sealing effect. Furthermore, the connection portion 1151 is provided with a fourth limiting platform 11511 to limit the axial movement of the first sealing element 150, ensuring that the first sealing element 150 will not detach from the cap body 110 when the container cap 100 is removed. Preferably, the mating surface between the first sealing element 150 and the opening 210 is a second frustum-shaped surface 211, with the smaller end of the second frustum-shaped surface 211 facing the side of the elastic claw 112. The second frustum surface 211 increases the contact area between the first seal 150 and the opening 210, which helps to improve the sealing performance of the first seal 150. The elastic claw 112 is provided with a fifth limiting platform 117 extending outward at the end away from the protrusion. The fifth limiting platform 117 and the above-mentioned connecting part 1151 apply pressure to the first seal 150. This pressure acts on the second frustum surface 211 between the first seal 150 and the opening 210, which further improves the sealing performance of the first seal 150.

[0066] Please see Figure 6 , Figure 8 , Figure 13 and Figure 15 In one example of the present invention, a wall 116 is provided on the cover body 110 and slidably connected to the core body 120. The wall 116 is located inside the elastic claw 112 and is coaxial with the elastic claw 112. The inner cavity of the wall 116 is a first through hole 111. A first limiting platform 1161 protruding towards the inner side of the wall 116 is provided on the inner side of the wall 116. A second limiting platform 122 protruding outward is provided on the circumference of the core body 120. The two ends of the elastic member abut against the first limiting platform 1161 and the second limiting platform 122 respectively. The second limiting platform 122 is provided on the core body 120. The elastic body 130 is fitted on the outer periphery of the core body 120, and the two ends of the elastic body 130 abut against the first limiting platform 1161 and the second limiting platform 122 respectively, so as to realize that the core body 120 and the operating body 140 are kept in contact.

[0067] Please see Figure 6 , Figure 8 , Figure 14 and Figure 15 In one example of the present invention, the core 120 includes a first structure 123 and a second structure 124. The first structure 123 and the second structure 124 are detachably connected. The detachable connection can be a threaded connection, a tenon and mortise connection or a snap-fit ​​connection. The separate configuration of the core 120 improves the processing performance of the core 120 and the assembly performance of the container cap 100. The side of the first structure 123 facing away from the second structure 124 abuts against the operating body 140, that is, the aforementioned curved protrusion 121 is provided on the side of the first structure 123 facing away from the second structure 124.

[0068] For further information, please refer to [link / reference]. Figure 6 , Figure 8 , Figure 14 and Figure 15 The second structure 124 includes a support portion 1241 for locking the elastic claw 112. The shape of the support portion 1241 is not limited. The support portion 1241 applies a force to the elastic claw 112 to deform toward the side where the opening 210 is located by the elastic force of the elastic body 130, so as to lock the elastic claw 112 with the container body 200 and prevent the protrusion 1121 from deforming and retracting toward the center side of the opening 210.

[0069] The support portion 1241 can have various structures; preferably, please refer to [reference needed]. Figures 8 to 9 and Figures 12 to 15 The mating surface between the support 1241 and the elastic claw 112 is a third frustum surface 1123, with the small end of the third frustum surface 1123 facing the direction in which the cover body 110 moves out of the opening 210 (i.e., Figure 2 (In the X direction). The third frustum surface 1123 can decompose the vertical elastic force of the elastic element into a component force on the elastic claw 112 away from the center and outward. At the same time, the third frustum surface 1123 can also guide the sliding of the support part 1241. It should be noted that the lower end of the positioning element 115 is provided with a fifth frustum surface 1152. Considering that the positioning element 115 is a rigid element and will not deform due to contact with the support part 1241, it is preferable that the size of the fifth frustum surface 1152 is greater than or equal to the size of the third frustum surface 1123, so as to prevent the support part 1241 from not being able to contact the elastic claw 112 due to the limitation of the positioning element 115.

[0070] Please see Figure 6 , Figure 8 and Figures 14 to 15In one example of the present invention, a one-way valve 125 is provided inside the second structure 124. The air inlet of the one-way valve 125 is connected to the external environment, and the air outlet of the one-way valve 125 is connected to the inner cavity of the container body 200. Specifically, a third through hole 1243 connecting the one-way valve 125 and the external environment is provided inside the first structure 123. The shape of the third through hole 1243 is not limited; it can be T-shaped as in this embodiment, or L-shaped or other irregular shapes, as long as it can achieve connection. The one-way valve 125 allows gas to enter from the outside of the container 10 to the inside of the container 10. The one-way valve 125 is a rubber part, which has a one-way ventilation function that allows gas to pass into the container 10 but prevents oil leakage to the outside, and meets the airtightness pressure, so that it reaches the inflation pressure of 0.5 to 0.8 bar without leakage. The one-way valve 125 allows gas to enter from the outside of the container 10, but prevents liquid in the container 10 from overflowing from the one-way valve 125.

[0071] Preferably, in one example of the present invention, please refer to Figures 14 to 15 The second structure 124 also includes a main body 1242, which is slidably fitted with the first through hole 111, and a support 1241 is connected to the outer periphery of the main body 1242. This configuration has good processing and assembly performance.

[0072] For a more stable installation of the check valve 125, please refer to an example of the present invention. Figures 14 to 15 The main body 1242 has a second through hole 1231 along the axial direction. A third limiting platform 1244 protruding towards the center is provided inside the second through hole 1231. A one-way valve 125 is installed in the second through hole 1231, and the flange of the one-way valve 125 abuts against the third limiting platform 1244. The first structure 123 is connected to the second structure 124 and presses the flange onto the third limiting platform 1244. This configuration has good processing performance and assembly performance.

[0073] In one example of the present invention, please refer to Figures 14 to 15 Considering the reliability of the connection between the first structure 123 and the second structure 124, the detachable method of the first structure 123 and the second structure 124 is set as a threaded connection. At the same time, a gasket 126 is provided between the one-way valve 125 and the first structure 123. The gasket 126 can protect the one-way valve 125 from friction during the rotation of the first structure 123 and the second structure 124. Preferably, a stop structure is provided between the gasket 126 and the one-way valve 125 to prevent relative rotation between the gasket 126 and the one-way valve 125. The stop structure can be a combination of a protrusion and a groove.

[0074] Please see Figure 6 , Figure 8 and Figure 10 In one example of the present invention, a second sealing element 160 is provided at the connection between the support portion 1241 and the main body portion 1242. The material of the second sealing element 160 can be EPDM rubber, fluorosilicone rubber, or fluororubber, but is not limited to these. The second sealing element 160 is disposed between the second structure 124 and the cover body 110. When the operating body 140 is in the first position, the second sealing element 160 is squeezed and pressed by the second structure 124 and the cover body 110 to achieve a seal between the core 120 and the cover body 110. In this embodiment, please refer to... Figures 6 to 9 The second sealing element 160 is pressed by the core 120 against the end of the first through hole 111 of the cover body 110 away from the operating body 140. Preferably, the mating surface between the second sealing element 160 and the cover body 110 is a fourth frustum surface 1111. The setting of the fourth frustum surface 1111 increases the contact area between the second sealing element 160 and the cover body 110, which is beneficial to improving the sealing performance of the second sealing element 160. At the same time, setting the mating surface to a frustum shape can utilize the self-locking phenomenon in physics to form a stable and reliable lock, further improving the sealing performance of the second sealing element 160.

[0075] In one example of the present invention, please refer to Figures 2 to 3 and Figures 6 to 9 When the container cap 100 is sealed and installed onto the container body 200, the first frustum 1122 formed by the elastic claw 112 and the opening 210, the second frustum 211 formed by the first sealing member 150 and the opening 210, the third frustum 1123 formed by the support part 1241 and the elastic claw 112, the fourth frustum 1111 formed by the second sealing member 160 and the cap body 110, and the fifth frustum 1152 formed by the lower end of the positioning member 115 and the support part 1241 are coaxial and tightly fitted at the same time to achieve the dual effects of locking and sealing. In addition to the above-mentioned beneficial effects, the frustum fit method in this setting also has a larger process window than other fit methods because the five fit surfaces need to fit tightly at the same time, which reduces the processing difficulty and processing cost.

[0076] In another example of the container lid 100 of the present invention, the connection between the operating body 140 and the lid body 110 is set as a sliding connection. The operating body 140 is slidably installed on the lid body 110 and reciprocates linearly between a first position and a second position to compress the core 120 to reciprocate within the first through hole 111. The operating body 140 can be locked in the first position and the second position to lock the core 120 in the corresponding position, thereby realizing the locking and unlocking of the container lid 100 and the container body 200. Specifically, when the operating body 140 is in the first position, the container lid 100 is locked to the container body 200. When the operating body 140 is in the second position, the container lid 100 is unlocked from the container body 200 and can be removed. There are various locking structures between the operating body 140 and the lid body 110, which can be obtained through commercial means and will not be described in detail here.

[0077] Considering the possibility of accidental contact with the operating body 140, in another embodiment of the container 10 of the present invention, please refer to... Figure 16 A boss 220 is provided on one side of the opening 210 of the container body 200. The boss 220 at least partially surrounds the operating body 140. It is preferable to rotate the gripping part 141 of the operating body 140 to the position of the boss 220. Furthermore, the height of the boss 220 is higher than that of the operating body 140 along the axial direction of the cover body 110, so as to protect the operating body 140 and prevent accidental contact. It should be noted that in other embodiments, the boss 220 can also be provided on the cover body 110 and made higher than the operating body 140 to form a protective platform to prevent accidental contact with the operating body 140.

[0078] In summary, the container lid of this invention has a core that is slidably mounted on the lid body and controlled by an operating body that is movably mounted on the lid body. When the operating body is in the first position, the core seals the opening. When the operating body is in the second position, the lid body unlocks from the opening, allowing the lid body to detach from the opening. This design achieves the locking and separation of the container lid and the container body through the up-and-down movement of the core, changing the existing method of locking the container lid by rotating it. When the operating body is in the first position, the container lid and the container body are locked; when the operating body is in the second position, the container lid and the container body are unlocked. This improves the problem of inconsistent tightening states of the container lid caused by different manual tightening forces. The locking force between the container lid and the container body can be controlled by the structure and size of the container lid, which can improve the problem of the container lid getting stuck and difficult to open due to excessive tightening and the adhesion of lubricating oil. In addition, the container lid changes the form of rotational locking by threads, breaking the limitation that the outer contour of the container lid must be circular. The above embodiments are only illustrative of the principles and effects of the invention and are not intended to limit the invention. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
