Description

Technical Field

[0001] This application relates to the field of packaging sealing technology, specifically to a sealing component structure. Background Technology

[0002] Packaging bags, as carriers for various products, are widely used in numerous fields. In actual production, most product packaging bags are not equipped with a resealable structure that can be opened and closed multiple times during the initial design stage. To achieve continuous production and improve efficiency, heat sealing technology is usually used to seal the packaging bags once. The principle of heat sealing technology is to use a heating device to melt the plastic film at the opening of the packaging, and then apply a certain pressure to make the film stick together, thereby achieving a sealing effect. However, when the product is not used up in one go, in order to prevent the remaining product inside the bag from getting damp and deteriorating, the packaging opening must be resealed.

[0003] In existing technologies, secondary sealing of packaging bags mainly employs methods such as clamp-type sealing component structures, clamp-type sealing component structures, and zipper-type sealing component structures to seal the packaging opening.

[0004] Clamp-type sealing components (such as a food packaging bag sealing clamp with patent application publication number CN 103287690 A and a packaging bag sealing clamp with patent authorization publication number CN 201099424 Y) work by having two clamps move towards each other to clamp the packaging opening and connect the clamps with snaps to achieve a seal. However, this type of sealing component structure has significant drawbacks: under external force, the clamps are prone to loosening, resulting in gaps at the seal and significantly reducing sealing performance. Furthermore, it has stringent requirements regarding the material and thickness of the packaging bag. For soft or thin packaging bags, the sealing component structure cannot provide sufficient clamping force, leading to an insecure seal. In addition, the clamp-type sealing component structure has fixed dimensions and cannot be adapted to the actual situation of the packaging opening.

[0005] Zipper-type sealing assembly structures (such as the environmentally friendly plastic sealing assembly structure for composite packaging with patent authorization announcement number CN 208761229 U) mainly achieve sealing of the opening of environmentally friendly composite packaging by the reciprocating sliding of the zipper head on the main body of the sealing assembly structure (including sealing chain one and sealing chain two). However, this method has specific requirements on the shape of the packaging opening; if the shape of the packaging opening is irregular, effective sealing cannot be achieved.

[0006] Clamp-type sealing components (such as the secondary sealing clamp for packaging bags in patent publication number CN 205470488 U, and the sealing rod and packaging device in application publication number CN 102442469 A) mainly consist of an outer clamp and an inner clamp. The outer clamp has a slit. During sealing, the inner clamp must first be placed at the opening of the packaging. Then, the opening is fixed around the inner clamp by folding or rolling. Finally, the packaging bag and the inner clamp are inserted together from one end of the outer clamp, clamping the bag tightly within the slit. This method is laborious and extremely inconvenient. Utility Model Content

[0007] In view of the above problems, this application provides a sealing component structure that solves the problems of poor sealing performance and laborious operation of existing sealing component structures.

[0008] To achieve the above objectives, the inventors provide a sealing assembly structure, which includes a sealing body, a sealing element, and a slider;

[0009] The sealing body has a cavity for accommodating the sealing element and the packaging opening of the packaging bag, and the sealing element is provided with a first opening communicating with the cavity;

[0010] The slider is slidably connected to the sealing body; it has a second opening corresponding to the first opening that connects to the cavity, and a slit along the sliding direction that leads from the second opening to one end of the slider; the slider has a separation part extending into the bottom of the cavity at the end opposite to the slit.

[0011] One end of the sealing element is located inside the cavity, and the other end is located outside the cavity through the first opening and the second opening in sequence.

[0012] The packaging opening of the packaging bag surrounds the outer periphery of the seal; by sliding the slider, the two sides of the packaging opening of the packaging bag are located in the slit, and the other end of the seal and the packaging opening of the packaging bag enter or leave the cavity in sequence through the second opening and the first opening.

[0013] Furthermore, the cavity extends through both ends of the sealing body.

[0014] Furthermore, the width of the first opening is smaller than the width of the cavity, and the seal is formed of an elastic material; a sliding slider is used to squeeze the other end of the seal and the packaging opening of the packaging bag through the first opening into or out of the cavity.

[0015] Furthermore, the sealing element is arc-shaped corresponding to the first opening.

[0016] Furthermore, the slider is provided with a channel passing through both ends of the slider along the sliding direction, and the sealing body is slidably connected in the channel.

[0017] Furthermore, the slit is located on one side of the second opening.

[0018] Furthermore, the separation section has a guide surface extending from the second opening to the bottom of the cavity for the first opening.

[0019] Furthermore, one end of the slider has a flared structure on the side opposite to the slit.

[0020] Furthermore, the slider is provided with a guide plate at the second opening, and the guide plate extends from one end of the second opening in a direction away from the sealing body.

[0021] Furthermore, it also includes a limiting block, which is connected to both ends of the sealing body.

[0022] Unlike existing technologies, the above-mentioned technical solution uses a sliding slider to allow the packaging opening and seal to gradually enter or leave the cavity under the action of the slider. When the packaging opening and seal of the packaging bag enter the cavity, the cavity and seal squeeze the two sides of the packaging opening so that the two sides of the packaging opening can be tightly fitted together, thereby forming a good seal and preventing the contents from getting damp, deteriorating or leaking. At the same time, the entire sealing and unsealing operation is completed by a simple sliding slider action, which greatly reduces the difficulty of use and thus significantly improves the efficiency of packaging and unsealing.

[0055] See Figures 1-8 As shown, a sealing assembly structure includes a sealing body 10, a sealing element 30, and a slider 20. A cavity 101 is provided in the sealing body 10 to accommodate the sealing element 30 and the packaging opening 501 of a packaging bag 50. The packaging opening 501 of the packaging bag 50 surrounds the sealing element 30. By sliding the slider 20, the packaging opening 501 and the sealing element 30 gradually enter or leave the cavity 101. When the packaging opening 501 and the sealing element 30 enter the cavity 101, the cavity 101 and the sealing element 30 compress both sides of the packaging opening 501, ensuring a tight seal and preventing the contents from becoming damp, deteriorating, or leaking. Simultaneously, the entire sealing and unsealing operation is completed through the simple movement of the slider 20, greatly reducing the difficulty of use and significantly improving the efficiency of sealing and unsealing.

[0056] The aforementioned sealing component structure can seal the packaging opening 501 of various product packaging bags 50, including but not limited to the following: for example, packaging tea, coffee, etc., to maintain the aroma of tea and coffee and prevent oxidation and moisture intrusion; for packaging food, medicine, etc., such as meat (dried meat, ham, etc.), seafood (fish, shrimp, shellfish, etc.), dairy products (milk powder, cheese, etc.), vegetables, fruits, pastries, and candies, to extend their shelf life, prevent oxidation and microbial growth, and maintain the quality and taste of the food; for medicines and herbs, to maintain their active ingredients and prevent oxidation and moisture intrusion; and of course, it can also be used for industrial parts, protecting them from oxidation and corrosion, and ensuring their integrity and quality during transportation and storage.

[0057] See Figure 1-4 As shown below, the present invention provides a specific embodiment of a sealing component structure, which includes a sealing body 10, a sealing element 30, and a slider 20;

[0058] The sealing body 10 has a cavity 101 that accommodates the sealing element 30 and the packaging bag 50, and the sealing element 30 is provided with a first opening 102 that communicates with the cavity 101.

[0059] The slider 20 is slidably connected to the sealing body 10; it is provided with a second opening 202 corresponding to the first opening 102, which communicates with the cavity 101, and a slit 203 is provided along the sliding direction from the second opening 202 to one end of the slider 20; the slider 20 is provided with a separation part 204 extending into the bottom of the cavity at the end away from the slit 203.

[0060] One end of the sealing element 30 is located inside the cavity 101, and the other end is located outside the cavity 101 through the first opening 102 and the second opening 202 in sequence.

[0061] The packaging opening 501 of the packaging bag 50 surrounds the outer periphery of the sealing member 30; the sliding slider 20, the two sides of the packaging opening 501 of the packaging bag 50 are located in the slit 203, and the other end of the sealing member 30 and the packaging opening 501 of the packaging bag 50 enter or leave the cavity 101 in sequence through the second opening 202 and the first opening 102.

[0062] The cavity 101 of the aforementioned sealing body 10 is used to accommodate the sealing element 30 and the packaging opening 501 of the packaging bag 50. The lengths of the cavity 101 and the sealing element 30 can be determined based on the length of the packaging opening 501 of the packaging bag 50. The cavity 101 can also extend through both ends of the sealing body 10 (e.g., ...). Figure 1As shown, the sealing element 30 is set according to the length of the cavity 101. The cavity 101 extends through both ends of the sealing body 10 and can flexibly adapt to the packaging openings 501 of packaging bags 50 of different lengths. When facing packaging openings 501 of packaging bags 50 of different lengths, the sealing body 10 and the sealing element 30 can be cut according to the length of the packaging opening 501 of the packaging bag 50 to ensure that all parts of the packaging opening 501 of the packaging bag 50 can be effectively sealed. This allows the sealing component structure to adapt to packaging openings 501 of packaging bags 50 of various lengths, greatly improving its versatility and applicability. This embodiment does not limit the shape of the cavity 101. As long as the packaging opening 501 of the packaging bag 50 surrounds the outer periphery of the sealing element 30, and the packaging opening 501 of the packaging bag 50 and the sealing element 30 enter the cavity 101 together, the cavity 101 and the sealing element 30 squeeze the two sides of the packaging opening 501 so that the two sides of the packaging opening 501 can fit tightly together, thereby forming a good sealing state. Preferably, the shape of the cavity 101 is adapted to the shape of the seal 30. This adaptation allows for a tighter fit between the seal 30 and the cavity 101, resulting in a more even distribution of force when the packaging opening 501 of the packaging bag 50 is squeezed. For example, if the seal 30 is a square column and the cavity 101 is correspondingly square column-shaped, then during the squeezing process, the pressure on both sides of the packaging opening 501 of the packaging bag 50 will be evenly distributed around the circumference, avoiding excessive or insufficient local pressure. This allows the two sides of the packaging opening 501 to fit together more tightly, forming a good seal and effectively preventing the contents from getting damp, deteriorating, or leaking. Especially when subjected to external forces (such as bumps during transportation or squeezing during storage), the adaptation allows the seal 30 to better withstand pressure and evenly transmit the force to the cavity 101, avoiding structural deformation or damage due to shape mismatch, thus ensuring the reliability of the sealing function. This embodiment also does not limit the shape of the packaging opening 501 of the packaging bag 50. It can be any shape. As long as it meets the requirement of sealing, the packaging opening 501 of the packaging bag 50 is completely located in the cavity 101 or both sides of the packaging opening 501 are located in the cavity 101. The cavity 101 and the sealing member 30 squeeze the two sides of the packaging opening 501 so that the two sides of the packaging opening 501 can fit tightly together, thereby forming a good sealing state.

[0063] The sealing element 30 and the packaging opening 501 of the packaging bag 50 enter the cavity 101 through the first opening 102 of the sealing body 10. The shape of the first opening 102 can be set to correspond to the shape of the sealing element 30, which can minimize the resistance during entry and ensure that the sealing element 30 and the packaging opening 501 of the packaging bag 50 can enter smoothly. The minimum size of the first opening 102 should ensure that the sealing element 30 and the packaging opening 501 of the packaging bag 50 surrounding it can pass smoothly. In some embodiments not shown, the width of the first opening 102 is equal to the width of the cavity 101; the sealing element 30 and the packaging opening 501 of the packaging bag 50 surrounding it form an interference fit with the cavity 101 through the first opening 102. In some embodiments not shown, the width of the first opening 102 is equal to the width of the cavity 101. Elastic edges are provided on both side walls of the first opening 102. When the sealing member 30 and the packaging bag 50 opening 501 surrounding it pass through the first opening 102, the elastic edges undergo elastic deformation. After the sealing member 30 and the packaging bag 50 opening 501 enter the cavity 101, the elastic edges return to their normal state. The elastic edges on both side walls of the first opening 102 provide support for the sealing member 30 and the packaging bag 50 opening 501, effectively preventing the sealing member 30 and the packaging bag 50 opening 501 from sliding out of the cavity 101 after insertion. See also... Figure 1 As shown, in some embodiments, to effectively prevent the sealing element 30 and the packaging bag 50 opening 501 surrounding it from accidentally sliding out of the cavity 101 during the sealing process, the width of the first opening 102 is smaller than the width of the cavity 101. That is, the combined size of the sealing element 30 and the packaging bag 50 opening 501 is slightly larger than the width of the first opening 102. When the sealing element 30 and the packaging bag 50 opening 501 surrounding it pass through the first opening 102, the sealing body 10 and / or the sealing element 30 undergo elastic deformation. After the sealing element 30 and the packaging bag 50 opening 501 surrounding it enter the cavity 101, the sealing body 10 and / or the sealing element 30 undergo elastic deformation. Or, when the seal 30 returns to its normal state, the side walls of the cavity 101 on both sides of the first opening 102 will form a tight clamping support for the seal 30 and the packaging bag 50 opening 501 surrounding it, effectively preventing the seal 30 and the packaging bag 50 opening 501 from sliding out of the cavity 101 after insertion, ensuring that they remain in a stable position within the cavity 101. Moreover, as subsequent sealing operations proceed, such as the sliding of the slider 20, this stable support is maintained throughout the entire sealing process, thus laying a solid foundation for achieving a tight fit on both sides of the packaging bag 50 opening 501 and a good sealing effect, effectively ensuring the sealing performance and reliability of the packaging.

[0064] In some embodiments, the elasticity of the sealing body 10 and the slider 20 is less than that of the sealing element 30. The relatively low elasticity of the sealing body 10 and the slider 20 facilitates positioning and sliding during operation, preventing positional difficulties due to excessive elasticity and ensuring accurate and efficient sealing. Simultaneously, it provides a certain degree of rigid support during sealing, ensuring that the sealing element 30 deforms more easily under the force of the sliding slider 20. During the sealing process, it can more easily deform and enter the cavity 101 through the first opening 102. After entering the cavity 101, it partially or completely recovers its shape, allowing it to better adapt to the packaging opening 501 of the packaging bag 50 with different shapes and surface conditions, fitting more tightly into the cavity 101, filling the small gaps between the cavity 101 and the sealing element 30. This ensures that the cavity 101 and the sealing element 30 effectively compress both sides of the packaging opening 501, allowing them to fit tightly together and form a good seal. Preferably, the elasticity of the sealing element 30, the slider 20, and the sealing body 10 decreases sequentially. The slider 20 and the sealing body 10 exhibit decreasing elasticity, providing rigid support and facilitating stable compression of the sealing element 30 during the sealing process. This reduces localized stress concentration and damage caused by elasticity mismatch, allowing for better sealing performance and ensuring the reliability and stability of the seal. The sealing body 10 and slider 20 can be molded from rubber, silicone, thermoplastic elastomers, thermoplastic vulcanizates, polyvinyl chloride, or metal materials (such as aluminum alloy or stainless steel). The sealing element 30 can be molded from rubber, silicone, thermoplastic elastomers, thermoplastic vulcanizates, or polyvinyl chloride.

[0065] See Figure 1 As shown, to facilitate smoother entry of the sealing element 30 and the packaging bag 50's opening 501 into the inner cavity, the sealing element 30 can be made arc-shaped corresponding to the first opening 102. When the arc-shaped end of the sealing element 30 enters the first opening 102, the contact area between the arc surface and the edge of the first opening 102 is relatively small, and the contact method is line contact or near-line contact, which greatly reduces friction. This facilitates the rapid entry of the sealing element 30 and the packaging bag 50's opening 501 around it into the inner cavity, avoiding deformation or jamming of the packaging bag 50's opening 501 due to excessive local pressure, making the entry process smoother and reducing the thrust required by the slider 20. At the same time, when the arc-shaped sealing element 30 enters the first opening 102, its shape guides it to find the correct entry direction more quickly, allowing the sealing element 30 and the packaging bag 50's opening 501 to quickly enter the inner cavity for sealing.

[0066] The aforementioned slider 20 is slidably connected to the sealing body 10, allowing sealing and unsealing operations to be completed by sliding the slider 20. In some embodiments not shown, the sealing body 10 has a guide rail on its side, and the slider 20 has a positioning block corresponding to the guide rail. The positioning block is slidably connected to the guide rail so that the slider 20 is slidably connected to the sealing body 10. See also Figures 1-4 As shown, in some embodiments, the slider 20 has a channel 201 extending through both ends of the slider 20 along the sliding direction. The sealing body 10 is slidably connected within the channel 201, allowing the slider 20 to be slidably connected to the sealing body 10. The second opening 202 of the slider 20 provides a clear movement trajectory for the other end of the sealing member 30 and the packaging opening 501 of the packaging bag 50, guiding the sealing member 30 and the packaging opening 501 of the packaging bag 50 into or out of the cavity 101. The sliding of the slider 20 causes the other end of the sealing member 30 to move. The movement of the second opening 202 and the slider 20 cooperate with each other, providing a point of action for the slider 20, enabling the slider 20 to effectively push the other end of the sealing member 30 into the cavity 101. The shape of the second opening 202 can correspond to the shape of the first opening 102, minimizing resistance during entry and ensuring that the sealing member 30 and the packaging opening 501 of the packaging bag 50 can smoothly enter or leave the cavity 101 through the second opening 202. The minimum size of the second opening 202 should ensure that the sealing element 30 and the packaging bag 50 surrounding it can pass through the packaging opening 501 smoothly; specifically, the width of the second opening 202 can be greater than or equal to the width of the first opening 102.

[0067] The aforementioned slit 203 provides a precise movement path for both sides of the packaging opening 501 of the packaging bag 50, ensuring that during the sliding of the slider 20, both sides of the packaging opening 501 of the packaging bag 50 move smoothly within the slit 203 under the guidance of the sealing element 30. This allows the other end of the sealing element 30 to smoothly drive the packaging opening 501 of the packaging bag 50 through the second opening 202 and the first opening 102 sequentially into or out of the cavity 101. The width of the slit 203 can be determined according to the thickness of the packaging bag 50 and can be greater than the thickness of the packaging bag 50. For example, for a common plastic packaging bag 50 with a thickness of 1-2 mm, the width of the slit 203 can be set to 2-3 mm to ensure that both sides of the packaging opening 501 of the packaging bag 50 can move freely within the slit 203. The slit 203 is set along the sliding direction, extending from the second opening 202 to one end of the slider 20, and can be located at any position between (including) the two sides of the second opening 202. See also Figure 1 and Figure 4As shown, the slit 203 is preferably located on one side of the second opening 202. Positioning the slit 203 on one side of the second opening 202 makes the slider 20 structure relatively concentrated and stable. Compared to a slit 203 located in the middle or other positions, a single-sided arrangement reduces the weakening of the overall structural strength of the slider 20 due to the slit 203. It is also less prone to deformation when subjected to the pressure generated by the sliding of the slider 20 and the squeezing force applied to the packaging opening 501 of the packaging bag 50, ensuring the structural stability and durability of the slider 20 and the entire sealing device.

[0068] The aforementioned separating part 204 is located at the end of the slider 20 opposite to the slit 203 and extends into the bottom of the cavity 101. It acts directly on the junction of the seal 30 and the packaging opening 501 with the bottom of the cavity 101. This ensures that the separating part 204 provides a stable and continuous force during the unsealing operation. As the slider 20 slides, the separating part 204 separates the seal 30 and the packaging opening 501 surrounding the packaging bag 50 of the seal 30 from the bottom of the cavity 101. This allows the separated seal 30 and the packaging opening 501 to exit the cavity 101 sequentially through the second opening 202 and the first opening 102. This effectively prevents the seal 30 or the packaging opening 501 from remaining at the bottom of the cavity during unsealing, ensuring a smooth unsealing process, improving the stability and repeatability of the unsealing operation, and enabling the unsealing operation to be completed quickly and efficiently.

[0069] To prevent the seal 30 and packaging opening 501 from becoming blocked in the cavity 101 or the first opening 102 during the unsealing process, and to ensure a quick and efficient unsealing operation, the separating part can be provided with a guide surface 2041 extending from the second opening towards the bottom of the cavity. That is, the guide surface 2041 extends from the other end of the second opening 202 into the bottom of the cavity 101. The guide surface 2041 provides a smooth and stable path for the seal 30 and the packaging opening 501 of the packaging bag 50 to enter or leave the cavity 101; specifically, the surface of the separating part 204 corresponding to the seal 30 can be a slope or a curved surface recessed into the cavity 101. Preferably, the separating part 204 and the slider 20 are integrally formed from the same material through injection molding, casting, or other processes, ensuring a strong connection between the separating part 204 and the slider 20, eliminating gaps, and resulting in high overall strength.

[0070] See Figure 3 and Figure 4As shown, in some embodiments, the slider 20 has a flared structure 205 on one end facing away from the slit 203. During the process of introducing the seal 30 and the packaging opening 501 into the slit 203, the flared structure 205 prevents them from colliding or rubbing against other parts of the slider 20, thereby protecting the seal 30, the packaging opening 501, and the slider 20 itself from damage. The flared structure 205 can be a gradually expanding type or a curved flared type. Taking a gradually expanding type as an example, the flared structure 205 has an inclined end face on the side of the slider 20 facing away from the slit 203.

[0071] See Figures 5-7 As shown, the packaging opening 501 of the packaging bag 50 surrounding the outer periphery of the sealing member 30 means that, with the sealing member 30 as the center, a portion of the packaging opening 501 surrounds the outer periphery of the sealing member 30 along its length, and the edge of the packaging opening 501 is tightly fitted to the outer periphery of the sealing member 30. By sliding the slider 20, both sides of the packaging opening 501 will move along the slit 203 of the slider 20, allowing the sealing member 30 and the packaging opening 501 of the packaging bag 50 to enter or exit the cavity 101 through the second opening 202 and the first opening 102, thus realizing the sealing and unsealing operation of the packaging opening 501 of the packaging bag 50. Specifically, when sealing is required, as the slider 20 continues to slide, the packaging opening 501 and the other end of the sealing element 30 gradually enter the cavity 101 under the action of the slider 20. At this time, the cavity 101 and the sealing element 30 work together to strongly compress both sides of the packaging opening 501. Under the pressure exerted by both, the two sides of the packaging opening 501 can fit tightly together, thus forming a good seal. When unsealing is required, the operation is equally convenient. Simply slide the slider 20 in the opposite direction, and the two sides of the packaging opening 501 will move in opposite directions within the slit 203 of the slider 20, allowing the packaging opening 501 and the other end of the sealing element 30 to leave the cavity 101 through the slider 20.

[0072] See Figure 3 and Figure 4 As shown, in some embodiments, the slider 20 is provided with a guide plate 206 at the second opening 202. The guide plate 206 extends from one end of the second opening 202 in a direction away from the sealing body 10. The guide plate 206 provides a smooth and stable path for the sealing element 30 and the packaging opening 501 of the packaging bag 50 to enter or leave the cavity 101. Specifically, the surface of the guide plate 206 corresponding to the sealing element 30 can be a slope or a curved surface recessed into the sealing body 10 (cavity 101). Preferably, the guide plate 206 and the slider 20 are integrally formed from the same material through processes such as injection molding and casting, so that the guide plate 206 and the slider 20 are firmly connected without any connection gaps, resulting in high overall strength.

[0073] It should be noted that the guide plate 206 and the flared structure 205 can coexist. They work together to greatly improve the smoothness and stability of the sealing element 30 and the packaging opening 501 of the packaging bag 50 entering and exiting the cavity 101.

[0074] To allow the slider 20 to slide out of the sealing body 10, limiting structures can be provided at both ends of the sealing body 10. In some embodiments not shown, the ends of the sealing body 10 are heat-melted to fully melt the material surfaces at both ends. Then, a certain pressure is rapidly applied to both ends of the sealing body 10 so that the projection of the end faces of both ends of the sealing body 10 in the sliding direction completely or partially covers the slider 20. The pressure is maintained until the material cools and solidifies, thereby restricting the slider 20 from sliding between the ends of the sealing body 10 and preventing the slider 20 from sliding out of the sealing body 10. See also Figure 8 As shown, in some embodiments, the sealing assembly structure further includes a limiting block 40, which is connected to both ends of the sealing body 10. The limiting block 40 defines a clear boundary for the movement of the slider 20, serving a positioning function and preventing it from slipping out of the sealing body 10. When the slider 20 slides on the sealing body 10 to perform sealing and unsealing operations, the limiting block 40 can prevent the slider 20 from continuing to move when it reaches the extreme positions at both ends, avoiding the slider 20 from accidentally detaching from the sealing body 10 and ensuring operational safety. There are various ways to connect the limiting block 40 to both ends of the sealing body 10, including but not limited to slot connection, threaded connection, and snap-fit ​​connection. Taking slot connection as an example, the limiting block 40 is provided with slots that match the shape of both ends of the sealing body 10. Both ends of the sealing body 10 are inserted into the slots to achieve the connection between the limiting block 40 and the sealing body 10. Through the tight fit of the slots, a stable connection between the limiting block 40 and the sealing body 10 is achieved.
