Description

Technical Field

[0001] This invention relates to the technical field of container caps, specifically to a container stopper that can be quickly disassembled and assembled, and its assembly method. Background Technology

[0002] Previously, if a component of a container stopper damaged, the entire stopper needed to be replaced. Replacing both damaged and undamaged parts together was wasteful of resources. Therefore, many modern container stoppers are detachable and modular. When a component fails, only the damaged part is replaced, and the stopper is reinstalled, effectively saving costs. However, current detachable stoppers require a specific installation sequence. Failure to follow this sequence will prevent proper installation, causing inconvenience to the user.

[0003] For example, in the current type of threadless, detachable container stopper, during assembly, the sealing ring must first be placed on the outer cover, and then the pull ring plug is inserted through the sealing ring to complete the assembly with the outer cover. If this assembly sequence is not followed, the locating pin of the pull ring plug will be stuck by the notch in the outer cover during the insertion process, preventing the pull ring plug from entering the outer cover to complete the assembly. Summary of the Invention

[0004] Therefore, it is necessary to provide a container plug that can be quickly disassembled and assembled, and its assembly method, which enables the container plug to be installed in no particular order.

[0005] A quick-release container stopper includes a hollow handle, a stopper body, and a resilient sealing sleeve.

[0006] The plug body includes a positioning pin block and a spring pressing pin, wherein the spring pressing pin abuts against or separates from the positioning pin block as it moves away from or towards the positioning pin block;

[0007] The hollow handle includes a limiting boss, the limiting boss has at least one guide rail, and the guide rail has an elastic limiting member at a first preset position; the connection between the guide rail and the elastic limiting member is provided with a groove or notch.

[0008] The plug is inserted into the elastic sealing sleeve and passes through the hollow handle along the guide rail. The elastic limiting member and the spring pressing pin abut against each other during the relative movement of the hollow handle and the plug. The elastic limiting member undergoes elastic deformation during the continued relative movement of the hollow handle and the plug, causing the guide rail to move against the positioning pin block in opposite directions, so that both ends of the elastic sealing sleeve are connected to the hollow handle and the plug respectively. The elastic limiting member then returns to its original deformation.

[0009] In one embodiment, one end of the guide rail has an arc surface or a sloped structure.

[0010] In one embodiment, the first end face of the elastic limiting member is an arc surface or a sloped surface structure.

[0011] In one embodiment, the second end face, which is provided corresponding to the first end face, is an arc surface or a sloped surface structure.

[0012] In one embodiment, the elastic limiting member is used to control the spring pressing pin to abut or separate from the positioning pin block, and after abutting against the plug body when the plug body passes through the limiting boss, it generates elastic deformation under the action of the groove or notch, and recovers its deformation when separated from the plug body.

[0013] A method for assembling a container stopper that can be quickly disassembled and reassembled.

[0014] S1. Place the elastic sealing sleeve onto the limiting boss or plug;

[0015] S2. Ensure that the guide rail and the positioning pin are on the same plane in the vertical direction;

[0016] S3. Ensure that the elastic limiting element and the spring pressing pin are on the same plane in the vertical direction;

[0017] S4. The plug moves along the guide rail toward the hollow handle so that the elastic limiting member and the spring pressing pin abut against each other and make relative movements.

[0018] S5. The spring-pressing pin moves away from the positioning pin block under the resistance of the elastic limiting element and separates from the positioning pin block.

[0019] S6. The elastic limiting member undergoes elastic deformation during the continued relative movement with the plug, and recovers its deformation when the plug moves away from the elastic limiting member;

[0020] S7. The positioning pin block moves relative to the guide rail due to pressure.

[0021] S8. Until the elastic sealing sleeve is in a critical deformation state;

[0022] S9. Connect the two ends of the elastic sealing sleeve to the hollow handle and the plug body respectively.

[0023] In one embodiment, in S1, when the elastic sealing sleeve is fitted onto the limiting boss or plug, the elastic sealing sleeve must fit tightly against the limiting boss or plug.

[0024] In one embodiment, in S7, the positioning pin blocks move towards each other until the outer edges of the positioning pin blocks are completely pressed into the plug body by the guide rail.

[0025] The aforementioned quick-release container stopper and its assembly method utilize an elastic limiting component. When the elastic sealing sleeve is fitted onto the limiting boss or the stopper body, the stopper body moves along the guide rail towards the hollow handle. This causes the elastic limiting component and the spring pressing pin to abut against each other during the relative movement of the hollow handle and the stopper body. The spring pressing pin is then pressed down, causing the guide rail to press the positioning pin block towards each other. The elastic limiting component deforms, allowing the stopper body to pass through the hollow handle and reach a preset position. The elastic limiting component then returns to its original shape, completing the assembly of the container stopper. Whether the elastic sealing sleeve is fitted onto the limiting boss or the stopper body first, the assembly of the container stopper can be completed smoothly without following a specific assembly sequence, making the assembly of the container stopper faster and more convenient.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediary component present. Conversely, when a component is said to be "directly" connected to another component, there is no intermediary component.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, a quick-release container stopper includes a hollow handle 100, a stopper body 200, and a resilient sealing sleeve 300.

[0034] The plug body 200 includes a positioning pin block 210 and a spring pressing pin 220, wherein the spring pressing pin 220 abuts against or separates from the positioning pin block 210 as it moves away from or closer to the positioning pin block 210.

[0035] The hollow handle 100 includes a limiting boss 110, the limiting boss 110 has at least one guide rail 111, and the guide rail 111 has an elastic limiting member 112 at a first preset position; the connection between the guide rail 111 and the elastic limiting member 112 is provided with a groove 1111 or a notch.

[0036] The plug 200 is inserted into the elastic sealing sleeve 300 and passes through the hollow handle 100 along the guide rail 111. The elastic limiting member 112 and the spring pressing pin 220 abut against each other during the relative movement of the hollow handle 100 and the plug 200. The elastic limiting member 112 undergoes elastic deformation during the continued relative movement of the hollow handle 100 and the plug 200, causing the guide rail 111 to move towards the positioning pin block 210, so that both ends of the elastic sealing sleeve 300 are connected to the hollow handle and the plug respectively. The elastic limiting member 112 then returns to its original deformation.

[0037] In one embodiment, one end of the guide rail 111 has an arc surface or a slope structure.

[0038] In one embodiment, the first end face of the elastic limiting member 112 is an arc surface or a sloped structure.

[0039] In one embodiment, the second end face 1122, which is provided corresponding to the first end face 1121, is an arc surface or a sloped surface structure.

[0040] In one embodiment, the elastic limiting member 112 is used to control the spring pressing pin 220 to abut or separate from the positioning pin block 210, and after abutting against the plug body 200 through the limiting protrusion 110, it undergoes elastic deformation under the action of the groove 1111 or notch, and recovers its deformation when separated from the plug body 200.

[0041] A method for assembling a container stopper that can be quickly disassembled and reassembled.

[0042] S1. Fit the elastic sealing sleeve 300 onto the limiting boss 110 or the plug 200.

[0043] S2. Make the guide slide rail 111 and the positioning pin block 210 on the same plane in the vertical direction;

[0044] S3. Make the elastic limiting member 112 and the spring pressing pin 220 on the same plane in the vertical direction;

[0045] S4. The plug 200 moves along the guide rail 111 toward the hollow handle 100 so that the elastic limiting member 112 abuts against the spring pressing pin 220 and makes relative movement.

[0046] S5. The spring pressing pin 220 moves away from the positioning pin block 210 under the resistance of the elastic limiting member 112 and separates from the positioning pin block 210.

[0047] S6. The elastic limiting member 112 undergoes elastic deformation during the continued relative movement with the plug body 200, and recovers its deformation when the plug body 200 moves away from the elastic limiting member 112.

[0048] S7, the positioning pin 210 moves relative to the guide rail 111 under pressure;

[0049] S8, until the elastic sealing sleeve 300 is in a critical deformation state;

[0050] S9. Connect the two ends of the elastic sealing sleeve 300 to the hollow handle 100 and the plug body 200 respectively.

[0051] In one embodiment, in S1, when the elastic sealing sleeve 300 is fitted onto the limiting boss 110 or the plug 200, the elastic sealing sleeve 300 must fit tightly against the limiting boss 110 or the plug 200.

[0052] In one embodiment, in S7, the positioning pin 210 moves towards each other until the outer edge of the positioning pin 210 is completely pressed into the plug body 200 by the guide rail.

[0053] The existing threadless container stopper consists of an outer cap, a sealing ring, and a pull-ring plug. The pull-ring plug includes a locating pin and a pressing pin. When the outer cap, sealing ring, and pull-ring plug are disassembled, the locating pin and pressing pin are in a mutually abutting state, preventing the two locating pins from moving towards each other, i.e., preventing them from retracting into the pull-ring plug. The sealing ring has two protrusions, and the outer cap has two notches. During assembly, the sealing ring is first fitted onto the outer cap, allowing the two protrusions within the sealing ring to be accommodated within the two notches of the outer cap. The pull-ring plug then passes through the sealing ring, and after the locating pin abuts against the protrusions, the locating pin slides past the protrusions, allowing the pull-ring plug to be inserted into the outer cap, thus completing the assembly of the container stopper. If the assembly is not performed in the above order, and the sealing ring is first placed inside the pull ring plug, and then the pull ring plug and the sealing ring are assembled together into the outer cover, the positioning pin and the pressing pin will be in a mutually abutting state. The positioning pin cannot retract into the pull ring plug, so the positioning pin will abut against the two notches on the outer cover and cannot enter the outer cover, resulting in the inability to complete the assembly.

[0054] Based on the above problems, this application is for a threadless container plug that can be installed in a disordered manner.

[0055] There is one or two guide rails 111. An elastic limiting member 112 is disposed on the inner layer of the limiting boss 110. Its specific position is determined by the position of the spring pressing pin 220. The elastic limiting member 112 is located at the longitudinal displacement of the spring pressing pin 220, and is aligned vertically with the spring pressing pin 220. This ensures that before the guide rail 111 presses against the positioning pin block 210, the elastic limiting member 112 presses against the spring pressing pin 220, allowing the two positioning pin blocks 210 to move towards each other. The elastic limiting member 112 has a certain degree of elasticity and will deform to a certain extent after being compressed.

[0056] When assembling the hollow handle 100, the plug body 200, and the elastic sealing sleeve 300, the elastic sealing sleeve 300 can be first fitted onto the limiting boss 110, or it can be first fitted onto the plug body 200. At this time, the positioning pin 210 and the spring pressing pin 220 are in a mutually abutting state, and the two positioning pins 210 cannot move towards each other. When the plug body 200 is inserted into the hollow handle 100, the positioning pin 210 on the plug body 200 and the guide rail 111 are in a vertical position. As the plug body 200 is gradually inserted into the hollow handle 100 along the same straight line, the elastic limiting member 112 abuts against the spring pressing pin 220 and presses the spring pressing pin 220 to move towards the elastic sealing sleeve 300, causing the spring pressing pin 220 to separate from the positioning pin block 210. At this time, due to the action of the guide slide rail 111, the two positioning pin blocks 210 are pressed together and move towards each other, retracting into the plug body 200. The plug body 200 continues to move until the elastic sealing sleeve 300 reaches the critical deformation state, completing the assembly.

[0057] In this way, the container stopper can be quickly assembled and disassembled. With the setting of the elastic limiting member 112, when the elastic sealing sleeve 300 is put on the limiting boss 110 or the stopper body 200, the stopper body 200 moves along the guide slide rail 111 towards the hollow handle 100, so that the elastic limiting member 112 abuts against the spring pressing pin 220 and presses down the spring pressing pin 220, so that the guide slide rail 111 presses the positioning pin block 210 towards each other, the elastic limiting member 112 deforms, so that the stopper body 200 passes through the hollow handle 100 and reaches the preset position. The elastic limiting member 112 returns to its deformation, and the assembly of the container stopper is completed. Whether the elastic sealing sleeve 300 is put on the limiting boss 110 or the stopper body 200 first, the assembly of the container stopper can be completed smoothly without following a certain assembly sequence, making the assembly of the container stopper faster and more convenient.

[0058] Furthermore, in order to enable the positioning pin 210 to quickly enter the limiting boss 110, the guide slide rail 111 and the two sides of the limiting boss 110 are provided with grooves or notches.

[0059] Thus, when the positioning pin 210 abuts against the guide slide rail 111, the guide slide rail 111 has grooves 1111 or notches on both sides, so that the guide slide rail 111 is slightly raised outward, making it easier for the positioning pin 210 to slide into the limiting boss 110.

[0060] Furthermore, in order to facilitate the sliding of the positioning pin 210 into the limiting boss 110, one end of the guide rail 111 is an arc surface or a sloped surface structure.

[0061] Thus, when the plug 200 moves toward the hollow handle 100 under the action of external force, and the lower edge of the guide slide rail 111 abuts against the positioning pin 210, the positioning pin 210 can quickly enter the limiting boss 110 because the end of the guide slide rail 111 near the positioning pin 210 has an arc or inclined structure.

[0062] like Figure 4 As shown, further, in order to enable the container plug to be disassembled quickly, the first end face 1121 on the elastic limiting member 112 is an arc surface or a sloped surface structure.

[0063] In this way, when the container stopper is disassembled, it is only necessary to separate the hollow handle 100 and the stopper body 200 under the action of external force. During the separation process of the stopper body 200 and the hollow handle 100, the first end face 1121 on the elastic limiting member 112 is an arc surface or inclined surface structure, which allows the stopper body 200 to slide quickly through the elastic limiting member 112 and quickly complete the disassembly of the container stopper.

[0064] Furthermore, in order to facilitate the rapid sliding of the spring pressing pin 220 through the elastic limiting member 112, the second end face 1122, which is provided corresponding to the first end face 1121, is a rounded corner, arc surface, or inclined surface structure.

[0065] Thus, during the assembly of the container stopper, when the elastic limiting member 112 and the spring pressing pin 220 abut against each other, the elastic limiting member 112 pushes the spring pressing pin 220 to move towards the base of the stopper body 200. Under the action of external force, the stopper body 200 continues to move into the hollow handle 100, and the spring pressing pin 220 slides past the elastic limiting member 112. Since the second end face 1122 of the elastic limiting member 112 near the spring pressing pin 220 is an arc surface or a sloped surface structure, it is convenient for the spring pressing pin 220 and the positioning pin block 210 to slide quickly through the elastic limiting member 112, and quickly complete the assembly.

[0066] Furthermore, in order to facilitate the quick passage of the positioning pin 210 through the elastic limiting member 112 during assembly, the elastic limiting member 112 is used to control the spring pressing pin 220 to abut or separate from the positioning pin 210, and to abut against the plug 200 and generate elastic deformation when the plug 200 passes through the limiting boss 110, and to restore deformation when the plug 200 slides through the elastic limiting member 112.

[0067] Thus, during the relative movement of the hollow handle 100 and the plug 200, the positioning pin 210 needs to slide through the elastic limiting member 112 before the assembly of the hollow handle 100 and the plug 200 can be completed. Because the elastic limiting member 112 is an elastic limiting member, when the positioning pin 210 slides and presses the elastic limiting member 112, the elastic limiting member 112 will undergo a certain degree of deformation, which facilitates the positioning pin 210 to slide quickly through the elastic limiting member 112. When the positioning pin 210 stops pressing the elastic limiting member 112, the elastic limiting member 112 returns to its original shape, ensuring that the assembly of the hollow handle 100 and the plug 200 is completed quickly.

[0068] Example 1: An assembly method for a container stopper that can be quickly disassembled and assembled.

[0069] S1. Fit the elastic sealing sleeve 300 onto the limiting boss 110;

[0070] S2. Make the guide slide rail 111 of the limiting boss 110 and the positioning pin block 210 on the plug body 200 on the same straight line in the vertical direction.

[0071] S3. Make the elastic limiting member 112 on the limiting boss 110 and the spring pressing pin 220 on the plug 200 in the same straight line in the vertical direction.

[0072] S4. The plug body 200 is inserted into the elastic sealing sleeve 300 and moves along the guide slide rail 111 toward the hollow handle 100, so that the elastic limiting member 112 abuts against the spring pressing pin 220.

[0073] S5. Under the action of the elastic limiting member 112, the spring pressing pin 220 moves towards the plug body 200 to the first preset position, so that the spring pressing pin 220 and the positioning pin block 210 no longer abut against each other.

[0074] S6. The guide slide rail 111 presses the positioning pin 210 and moves towards each other; the positioning pin 210 is pressed into the plug body 200 by the guide slide rail 111, and the elastic limiting member 112 deforms.

[0075] S7. The spring pressing pin 220 and the positioning pin block 210 slide sequentially through the elastic limiting member 112, and the elastic limiting member 112 restores its deformation.

[0076] S8. Make the elastic sealing sleeve 300 in a critical deformation state.

[0077] Example 2: A method for assembling a container stopper that can be quickly disassembled and assembled.

[0078] S1. Fit the elastic sealing sleeve 300 onto the plug body 200; so that the elastic sealing sleeve 300 abuts against the base of the plug body 200;

[0079] S2. Make the guide slide rail 111 of the limiting boss 110 and the positioning pin block 210 on the plug body 200 on the same straight line in the vertical direction.

[0080] S3. Make the elastic limiting member 112 on the limiting boss 110 and the spring pressing pin 220 on the plug 200 in the same straight line in the vertical direction.

[0081] S4. The plug body 200 drives the elastic sealing sleeve 300 to move along the guide slide rail 111 towards the hollow handle 100, so that the elastic limiting member 112 abuts against the spring pressing pin 220.

[0082] S5. The spring pressing pin 220 moves towards the plug body 200 in the direction of the elastic limiting member 112 under the action of the spring pressing pin 220, so that the spring pressing pin 220 and the positioning pin block 210 no longer abut against each other.

[0083] S6. The guide slide rail 111 presses the positioning pin 210 and moves towards each other; the positioning pin 210 is pressed into the plug body 200 by the guide slide rail 111, and the elastic limiting member 112 deforms.

[0084] S7. The spring pressing pin 220 and the positioning pin block 210 slide sequentially through the elastic limiting member 112, so that the elastic sealing sleeve 300 is sleeved on the limiting boss 110 and the upper end of the elastic sealing sleeve 300 abuts against the hollow handle; the elastic limiting member 112 restores its deformation.

[0085] S8. Make the elastic sealing sleeve 300 in a critical deformation state.

[0086] In this way, the assembly method of the container stopper, which allows for quick assembly and disassembly, involves placing the elastic sealing sleeve 300 on the limiting boss 110 or the stopper body 200. The stopper body 200 moves along the guide slide rail 111 towards the hollow handle 100, causing the elastic limiting member 112 to abut against the spring pressing pin 220. The spring pressing pin 220 is then pressed down, causing the guide slide rail 111 to press against the positioning pin block 210, which moves towards each other. The elastic limiting member 112 deforms, allowing the stopper body 200 to pass through the hollow handle 100 and reach the preset position. The elastic limiting member 112 then returns to its original deformation, bringing the elastic sealing sleeve 300 to a critical deformation state, thus completing the assembly of the container stopper. Whether the elastic sealing sleeve 300 is placed on the limiting boss 110 or the stopper body 200 first, the assembly of the container stopper can be completed smoothly without following a specific assembly sequence, making the assembly of the container stopper faster and more convenient.

[0087] Furthermore, in order to enable the container plug to be assembled quickly, in S1, when the elastic sealing sleeve 300 is fitted onto the limiting boss 110 or the plug body 200, the elastic sealing sleeve 300 must fit tightly against the limiting boss 110 or the plug body 200.

[0088] In this way, the elastic sealing sleeve 300 fits tightly with the limiting boss 110 or the plug 200, which can reduce the resistance during the process of the plug 200 being inserted into the limiting boss 110 and complete the assembly quickly.

[0089] In one embodiment, in S6, the positioning pin 210 moves towards each other until the outer edge of the positioning pin 210 is completely pressed into the plug body 200 by the guide rail 111.

[0090] During the sliding process of the plug body 200 toward the limiting boss 110, the outer edge of the positioning pin block 210 is tightly fitted with the inner wall of the limiting boss 110, so that the outer edge of the positioning pin block 210 is completely pressed into the plug body 200 by the guide slide rail 111, thus avoiding the positioning pin block 210 from protruding and affecting the assembly of the plug body 200 during the sliding process.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
