[0002] A reinforcement molding machine is a device used to strengthen and shape an object. It changes the physical properties and structure of an object through specific processes such as heating, pressurization, and glue injection, thereby enhancing its strength, stability, and durability. It is widely used in multiple manufacturing fields to meet the performance requirements of different products.

[0003] However, in the prior art, the existing cosmetic bottle mouth molding technology has many shortcomings. The traditional molding method is not perfect in strengthening the inner and outer sides of the bottle mouth. During the glue injection process, the operation steps are cumbersome and inefficient. It is impossible to inject glue on the inner and outer sides of the bottle mouth at the same time, which consumes a lot of time and labor costs. Summary of the invention

[0005] The shaping component includes a clamping block, a shunt pipe is fixedly connected to the top of the clamping block, a confluence shell is fixedly connected to the top of the confluence shell, a delivery hose is fixedly connected to the top of the confluence shell, and the telescopic cylinder drives the shaping component inside the shell to slide along the surface of the guide rod and approach each other, at which time the clamping blocks on both sides fit each other;

[0006] The feeding device includes a positioning frame, the inner side of the positioning frame is fixedly connected to a constant temperature glue liquid box, the top of the constant temperature glue liquid box is fixedly connected to a high temperature glue liquid box, the bottom of the high temperature glue liquid box is fixedly connected to a check assembly, the top of the constant temperature glue liquid box is fixedly connected to a lifting cylinder, the output end of the lifting cylinder is fixedly connected to a pushing assembly, and the bottom of the constant temperature glue liquid box is fixedly connected to a glue coating assembly, and the process of glue filling and conveying can be completed simultaneously during the lifting of the lifting cylinder.

[0007] Preferably, the inner wall of the clamping block is slidably connected to the outer wall of the guide rod, and the outer wall of the clamping block is fixedly connected to the output end of the telescopic cylinder. A threaded groove is provided in the wall of the clamping block. When the clamping blocks on both sides are fitted together, a threaded cavity will be formed at the threaded groove, thereby forming a closed threaded cavity on the outside of the bottle mouth.

[0008] Preferably, the bottom of the positioning frame is fixedly connected to the top of the shell, the side wall of the constant temperature glue liquid box is fixedly connected to the top of the conveying hose, the bottom of the check assembly is fixedly connected to the top of the constant temperature glue liquid box, and the inner wall of the constant temperature glue liquid box is slidably connected to the outer side of the pushing assembly to continuously input high-temperature glue liquid into the high-temperature glue liquid box. At this time, the high-temperature glue liquid can enter the constant temperature glue liquid box inside the positioning frame through the check assembly.

[0009] Preferably, the pushing assembly includes an elastic arc panel, the top of the elastic arc panel is rotatably connected to a connecting rod, the top of the connecting rod is rotatably connected to a support block, the top of the support block is fixedly connected to the output end of the lifting cylinder, and the side wall of the elastic arc panel is clamped with a sealing rubber ring, wherein the arc surface of the elastic arc panel is bent toward the side away from the support block, when the support block drives the elastic arc panel to move upward through the connecting rod, the sealing rubber ring on the outside of the elastic arc panel does not contact the inner wall of the constant temperature glue liquid box, and when the lifting cylinder drives the pushing assembly to move downward, under the action of the resistance of the glue below the pushing assembly, the support block approaches the elastic arc panel, and at this time, under the extrusion of the connecting rod, the elastic arc panel is deformed and forces the sealing rubber ring on its outside to contact the inner wall of the constant temperature glue liquid box.

[0010] Preferably, the non-return assembly includes a guide shell, the top of which is fixedly connected to a guide tube, the inner wall of the guide shell is slidably connected to a guide cylinder, the outer side of the guide cylinder is fixedly connected to a compression spring, and the high-temperature glue liquid can enter the constant temperature glue liquid box on the inner side of the positioning frame through the non-return assembly. During this process, the glue liquid enters the guide shell through the guide tube and pushes the guide cylinder in the guide shell to slide downward, forcing the compression spring to be compressed.

[0011] Preferably, the bottom end of the compression spring is fixedly connected to the inner wall of the guide shell, the outer wall of the guide shell is fixedly connected to the top of the constant temperature glue liquid box, the top of the guide tube is fixedly connected to the bottom of the high temperature glue liquid box, and a rectangular hole is opened in the wall of the guide tube, and the glue liquid can enter the constant temperature glue liquid box through the rectangular hole. When the glue liquid flows in the opposite direction, the compression spring drives the guide tube to reset, thereby preventing the glue liquid from flowing back during the glue injection process, resulting in unstable pressure during the glue injection.

[0012] Preferably, the glue coating assembly includes a fixed shell, the outer side of the fixed shell is fixedly connected to a side retaining ring, the inner wall of the side retaining ring is fixedly connected to a glue inlet pipe, the top of the fixed shell is fixedly connected to an air pump, the inner wall of the bottom of the fixed shell is provided with a rubber sleeve, the inner side of the rubber sleeve is clamped with an annular lining, the inner wall of the fixed shell is fixedly connected to a limiting assembly, and the positioning bolts and the annular lining can fix the rubber sleeve.

[0013] Preferably, the annular liner is fixedly connected to the inner wall of the fixed shell by positioning bolts, the limit assembly is fixedly connected to the center of the rubber sleeve, the top end of the glue inlet pipe is fixedly connected to the bottom of the constant temperature glue liquid box, and air is blown into the fixed shell by an air pump. At this time, the pressure in the fixed shell becomes large and forces the rubber sleeve to expand. After expansion, the rubber sleeve contacts the inner wall of the bottle mouth. At this time, the side retaining ring of the rubber sleeve and the inner wall of the bottle mouth can form a sealed space, and the glue in the feeding device can be injected into the sealed space through the glue inlet pipe.

[0014] Preferably, the limiting assembly includes a sleeve, an air guide plate is fixedly connected to the outer side of the sleeve, a sealing block is slidably connected to the inner wall of the sleeve, a coil spring is fixedly connected to the bottom of the sealing block, a hollow cylinder is fixedly connected to the bottom of the sleeve, and the inner wall of the hollow cylinder is slidably connected to the limiting plate. The deformation shape of the rubber sleeve is limited by setting the limiting assembly. When the air pump blows air, part of the gas is injected into the rubber sleeve through the air guide plate, and the rest of the gas enters the sleeve and pushes the sealing block to slide downward.

[0015] Preferably, the outer side of the air guide plate is fixedly connected to the inner wall of the fixed shell, the bottom end of the coil spring is fixedly connected to the inner wall of the sleeve, and the outer wall of the hollow cylinder is fixedly connected to the center of the rubber sleeve. When the coil spring is compressed, the hydraulic oil in the sleeve is injected into the hollow cylinder. At this time, the limit plate can slide out of the hollow cylinder under the push of the hydraulic oil, thereby limiting the deformation shape of the rubber sleeve.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention provides a shaping component. The telescopic cylinder drives the shaping component inside the shell to slide along the surface of the guide rod and approach each other. At this time, the clamping blocks on both sides fit each other and form a threaded cavity at the thread groove, thereby forming a closed threaded cavity on the outside of the bottle mouth. The rubber material in the feeding device can be injected into the confluence shell through the conveying hose, and finally injected into the threaded cavity through the shunt pipe. After cooling, a reinforced thread ring can be formed on the outside of the bottle mouth, thereby improving the structural strength of the bottle mouth.

[0018] 2. The present invention fixes the rubber sleeve by setting a glue coating component, setting positioning bolts and an annular liner, and then blowing air into the fixed shell through an air pump. At this time, the pressure in the fixed shell becomes large and forces the rubber sleeve to expand. After expansion, the rubber sleeve contacts the inner wall of the bottle mouth. At this time, the side retaining ring of the rubber sleeve and the inner wall of the bottle mouth can form a sealed space. The rubber in the feeding device can be injected into the sealed space through the rubber inlet pipe. After it is cooled, a reinforcement ring can be formed on the inner side of the bottle mouth, thereby further improving the structural strength of the bottle mouth.

[0019] 3. The present invention limits the deformation shape of the rubber sleeve by setting a limit assembly. When the air pump blows air, part of the gas enters the sleeve and pushes the sealing block to slide downward. At this time, the coil spring is compressed and the hydraulic oil in the sleeve is injected into the hollow cylinder. At this time, the limit plate can slide out of the hollow cylinder under the push of the hydraulic oil, thereby limiting the deformation shape of the rubber sleeve, thereby avoiding a gap between the rubber sleeve and the inner wall of the bottle mouth when injecting glue.

[0020] 4. The present invention sets a shaping component for use with a gluing component. When the device needs to be separated from the cosmetic bottle, the telescopic cylinder drives the compression blocks on both sides to separate, and then the air pump draws air to reset the limit component. At this time, the rubber sleeve returns to its original state, thereby quickly releasing the restriction on the inner and outer sides of the cosmetic bottle mouth, making the process of separating the device from the cosmetic bottle simpler and reducing the labor intensity of the staff.

[0021] 5. The present invention sets a check assembly, and the glue liquid enters the guide shell through the guide pipe, and pushes the guide cylinder in the guide shell to slide downward, forcing the compression spring to be compressed. At this time, the glue liquid can enter the constant temperature glue liquid box through the rectangular hole. When the glue liquid flows in the opposite direction, the compression spring drives the guide cylinder to reset, thereby preventing the glue liquid from flowing back during the glue injection process, resulting in unstable pressure during the glue injection.

[0022] 6. The present invention sets a pushing assembly, and the lifting cylinder drives the pushing assembly to move upward, wherein the arc surface of the elastic arc panel is bent toward the side away from the support block. When the support block drives the elastic arc panel to move upward through the connecting rod, the sealing rubber ring on the outside of the elastic arc panel does not contact the inner wall of the constant temperature glue liquid box. At the same time, under the restriction of the check assembly, the glue liquid can smoothly flow to the bottom of the pushing assembly, thereby quickly completing the glue filling process.

[0023] 7. The present invention sets a pushing assembly. When the lifting cylinder drives the pushing assembly to move downward, the support block approaches the elastic arc panel under the resistance of the rubber material below the pushing assembly. At this time, under the extrusion of the connecting rod, the elastic arc panel is deformed and forces the sealing rubber ring on its outer side to contact the inner wall of the constant temperature glue liquid box. At this time, the pushing assembly can push the glue liquid out of the constant temperature glue liquid box, thereby completing the process of rubber filling and conveying at the same time during the lifting of the lifting cylinder.

[0024] 8. The present invention provides a pusher assembly to simultaneously press the glue in the constant temperature glue tank into the glue inlet pipe and the delivery hose, thereby completing the glue injection process on the inside and outside of the cosmetic bottle mouth at the same time, reducing the operating steps of the staff and thus saving the time used for molding. The glue injection on the inside and outside of the bottle mouth can provide a stronger bonding force, so that the bottle mouth and related components are tightly combined. At the same time, the enhanced connection strength can ensure the integrity of the bottle mouth structure and reduce the risk of the bottle mouth loosening or damage due to external forces.

[0038] Example: See Figure 1-Figure 11 The present invention provides a technical solution: a bottle mouth strengthening molding machine for cosmetic bottles, comprising:

[0039] Shell 1, which is used to support the overall components of the molding machine. A handle 2 is fixedly connected to the outer side of the shell 1, and telescopic cylinders 3 are fixedly connected to both sides of the shell 1; a molding component 5, a guide rod 4 is slidably connected to the outer side of the molding component 5, and both ends of the guide rod 4 are fixedly connected to the outer side of the shell 1, and the output end of the telescopic cylinder 3 is fixedly connected to the outer side of the molding component 5; a feeding device 6, which is used to provide glue to the molding cavity of the molding component 5, the bottom of the feeding device 6 is fixedly connected to the top of the shell 1, and the top of the molding component 5 is fixedly connected to the outer side of the feeding device 6, and the shell 1 is driven to move by the handle 2, and the device is moved as a whole to the top of the mouth of the cosmetic bottle, and then the glue coating component 67 at the bottom of the feeding device 6 is placed on the inner side of the bottle mouth;

[0040] The shaping component 5 includes a clamping block 51, a shunt pipe 53 is fixedly connected to the top of the clamping block 51, a confluence shell 54 is fixedly connected to the top of the confluence shell 54, and a delivery hose 55 is fixedly connected to the top of the confluence shell 54. The telescopic cylinder 3 drives the shaping component 5 inside the shell 1 to slide along the surface of the guide rod 4 and approach each other. At this time, the clamping blocks 51 on both sides fit each other and form a threaded cavity at the thread groove 52, thereby forming a closed threaded cavity on the outside of the bottle mouth, and the rubber in the feeding device 6 can be injected into the confluence shell 54 through the delivery hose 55, and finally injected into the threaded cavity through the shunt pipe 53. After cooling, a reinforcing thread ring can be formed on the outside of the bottle mouth, thereby improving the structural strength of the bottle mouth;

[0041] The feeding device 6 includes a positioning frame 61, the inner side of the positioning frame 61 is fixedly connected to a constant temperature glue tank 62, the top of the constant temperature glue tank 62 is fixedly connected to a high temperature glue tank 63, the bottom of the high temperature glue tank 63 is fixedly connected to a check assembly 64, the top of the constant temperature glue tank 62 is fixedly connected to a lifting cylinder 65, the output end of the lifting cylinder 65 is fixedly connected to a pushing assembly 66, the bottom of the constant temperature glue tank 62 is fixedly connected to a glue coating assembly 67, the inner wall of the clamping block 51 is slidably connected to the outer wall of the guide rod 4, and the outer wall of the clamping block 51 is fixed to the output end of the telescopic cylinder 3 The wall of the clamping block 51 is provided with a threaded groove 52, the bottom of the positioning frame 61 is fixedly connected to the top of the housing 1, the side wall of the constant temperature glue tank 62 is fixedly connected to the top of the delivery hose 55, the bottom of the check assembly 64 is fixedly connected to the top of the constant temperature glue tank 62, the inner wall of the constant temperature glue tank 62 is slidably connected to the outer side of the push assembly 66, the push assembly 66 includes an elastic arc panel 661, the top of the elastic arc panel 661 is rotatably connected to a connecting rod 662, the top of the connecting rod 662 is rotatably connected to a support block 663, the top of the support block 663 is connected to The output end of the lifting cylinder 65 is fixedly connected, and the side wall of the elastic arc panel 661 is clamped with a sealing rubber ring 664. When injecting glue, the lifting cylinder 65 drives the push assembly 66 to move upward, wherein the arc surface of the elastic arc panel 661 is bent toward the side away from the support block 663. When the support block 663 drives the elastic arc panel 661 to move upward through the connecting rod 662, the sealing rubber ring 664 on the outer side of the elastic arc panel 661 does not contact the inner wall of the constant temperature glue tank 62. At the same time, under the restriction of the check assembly 64, the glue can flow smoothly to the bottom of the push assembly 66. , thereby the rubber filling process can be completed quickly; when the lifting cylinder 65 drives the pushing assembly 66 to move downward, under the resistance of the rubber below the pushing assembly 66, the support block 663 approaches the elastic arc panel 661. At this time, under the extrusion of the connecting rod 662, the elastic arc panel 661 is deformed and forces the sealing rubber ring 664 on its outer side to contact the inner wall of the constant temperature glue tank 62. At this time, the pushing assembly 66 can push the glue out of the constant temperature glue tank 62, thereby the rubber filling and conveying process can be completed simultaneously during the lifting and lowering process of the lifting cylinder 65.

[0042] The check assembly 64 includes a guide shell 641, a guide tube 642 is fixedly connected to the top of the guide shell 641, a guide cylinder 643 is slidably connected to the inner wall of the guide shell 641, a compression spring 644 is fixedly connected to the outer side of the guide cylinder 643, the bottom end of the compression spring 644 is fixedly connected to the inner wall of the guide shell 641, the outer wall of the guide shell 641 is fixedly connected to the top of the constant temperature glue tank 62, the top of the guide tube 642 is fixedly connected to the bottom of the high temperature glue tank 63, and a rectangular hole 645 is opened in the wall of the guide cylinder 643. When adding glue, the high temperature glue tank 63 is opened. High-temperature glue is continuously inputted into the interior, and at this time, the high-temperature glue can enter the constant temperature glue tank 62 on the inner side of the positioning frame 61 through the non-return assembly 64. During this process, the glue enters the guide shell 641 through the guide tube 642, and pushes the guide cylinder 643 in the guide shell 641 to slide downward, forcing the compression spring 644 to be compressed. At this time, the glue can enter the constant temperature glue tank 62 through the rectangular hole 645. When the glue flows in the opposite direction, the compression spring 644 drives the guide cylinder 643 to reset, thereby preventing the glue from flowing back during the injection process, resulting in unstable pressure during injection.

[0043] The glue coating component 67 includes a fixed shell 671, the outer side of the fixed shell 671 is fixedly connected with a side retaining ring 672, the inner wall of the side retaining ring 672 is fixedly connected with a glue inlet pipe 673, the top of the fixed shell 671 is fixedly connected with an air pump 674, the inner wall of the bottom of the fixed shell 671 is sleeved with a rubber sleeve 675, the inner side of the rubber sleeve 675 is clamped with an annular liner 676, the inner wall of the fixed shell 671 is fixedly connected with a limiting component 678, the annular liner 676 is fixedly connected to the inner wall of the fixed shell 671 by a positioning bolt 677, the limiting component 678 is fixedly connected to the center of the rubber sleeve 675, the top of the glue inlet pipe 673 is fixedly connected to the bottom of the constant temperature glue liquid box 62, and when the glue coating component 67 is in use, the rubber sleeve 675 is fixed by setting a positioning bolt 677 and annular liner 676, and then the air pump 674 is used to fix the rubber sleeve 675. The pump 674 blows air into the fixed shell 671. At this time, the pressure in the fixed shell 671 increases and forces the rubber sleeve 675 to expand. After expansion, the rubber sleeve 675 contacts the inner wall of the bottle mouth. At this time, the side retaining ring 672 of the rubber sleeve 675 and the inner wall of the bottle mouth can form a sealed space. The rubber material in the feeding device 6 can be injected into the sealed space through the rubber inlet pipe 673. After it is cooled, a reinforcement ring can be formed on the inner side of the bottle mouth, which further improves the structural strength of the bottle mouth. When it is necessary to separate the device from the cosmetic bottle, the telescopic cylinder 3 drives the clamping blocks 51 on both sides to separate, and then the air pump 674 draws air to reset the limit assembly 678. At this time, the rubber sleeve 675 returns to its original state, thereby quickly releasing the restrictions on the inner and outer sides of the bottle mouth of the cosmetic bottle, making the process of separating the device from the cosmetic bottle simpler and reducing the labor intensity of the staff.

[0044] The limiting assembly 678 includes a sleeve 761, an air guide plate 762 is fixedly connected to the outer side of the sleeve 761, a sealing block 763 is slidably connected to the inner wall of the sleeve 761, a coil spring 764 is fixedly connected to the bottom of the sealing block 763, a hollow cylinder 765 is fixedly connected to the bottom of the sleeve 761, and the inner wall of the hollow cylinder 765 is slidably connected to the limiting plate 766, the outer side of the air guide plate 762 is fixedly connected to the inner wall of the fixed shell 671, the bottom end of the coil spring 764 is fixedly connected to the inner wall of the sleeve 761, and the outer wall of the hollow cylinder 765 is fixedly connected to the center of the rubber sleeve 675. A limit assembly 678 is provided to limit the deformation shape of the rubber sleeve 675. When the air pump 674 blows air, part of the gas is injected into the rubber sleeve 675 through the air guide plate 762, and the remaining gas enters the sleeve 761 and pushes the sealing block 763 to slide downward. At this time, the coil spring 764 is compressed, and the hydraulic oil in the sleeve 761 is injected into the hollow cylinder 765. At this time, the limit plate 766 can slide out of the hollow cylinder 765 under the push of the hydraulic oil, thereby limiting the deformation shape of the rubber sleeve 675, thereby avoiding a gap between the rubber sleeve 675 and the inner wall of the bottle mouth when injecting glue.

[0045] Working principle:

[0046] When in use, the handle 2 drives the housing 1 to move, and the device as a whole is moved to the top of the mouth of the cosmetic bottle, and then the glue coating component 67 at the bottom of the feeding device 6 is placed inside the mouth of the bottle, and the telescopic cylinder 3 drives the shaping component 5 inside the housing 1 to slide along the surface of the guide rod 4 and approach each other, and the pressing blocks 51 on both sides fit each other, and a threaded cavity is formed at the thread groove 52, so that a closed threaded cavity can be formed on the outside of the bottle mouth, and the glue in the feeding device 6 can be injected into the confluence shell 54 through the conveying hose 55, and finally injected into the threaded cavity through the shunt pipe 53, and after cooling, a reinforcing thread ring can be formed on the outside of the bottle mouth, thereby improving the structural strength of the bottle mouth;

[0047] When the glue coating assembly 67 is in use, the rubber sleeve 675 is fixed by setting the positioning bolts 677 and the annular lining plate 676, and then the air pump 674 is used to blow air into the fixed shell 671. At this time, the pressure in the fixed shell 671 increases and forces the rubber sleeve 675 to expand. After the expansion, the rubber sleeve 675 contacts the inner wall of the bottle mouth. At this time, the side retaining ring 672 of the rubber sleeve 675 and the inner wall of the bottle mouth can form a sealed space. The glue in the feeding device 6 can be injected into the sealed space through the glue inlet pipe 673. After cooling, a reinforcement ring can be formed on the inner side of the bottle mouth, which further improves the structural strength of the bottle mouth.

[0048] At the same time, the deformation shape of the rubber sleeve 675 is limited by setting the limit assembly 678. When the air pump 674 blows air, part of the gas is injected into the rubber sleeve 675 through the air guide plate 762, and the remaining gas enters the sleeve 761 and pushes the sealing block 763 to slide downward. At this time, the coil spring 764 is compressed, and the hydraulic oil in the sleeve 761 is injected into the hollow cylinder 765. At this time, the limit plate 766 can slide out of the hollow cylinder 765 under the push of the hydraulic oil, and the deformation shape of the rubber sleeve 675 is limited, thereby avoiding the rubber sleeve 675 from having a gap with the inner wall of the bottle mouth when injecting glue;

[0049] When it is necessary to separate the device from the cosmetic bottle, the telescopic cylinder 3 drives the clamping blocks 51 on both sides to separate, and then the air pump 674 draws air to reset the limit assembly 678. At this time, the rubber sleeve 675 returns to its original state, thereby quickly releasing the restriction on the inner and outer sides of the cosmetic bottle mouth, making the process of separating the device from the cosmetic bottle easier and reducing the labor intensity of the staff.

[0050] When adding glue, high-temperature glue is continuously input into the high-temperature glue tank 63. At this time, the high-temperature glue can enter the constant temperature glue tank 62 on the inner side of the positioning frame 61 through the non-return assembly 64. During this process, the glue enters the guide shell 641 through the guide tube 642, and pushes the guide tube 643 in the guide shell 641 to slide downward, forcing the compression spring 644 to be compressed. At this time, the glue can enter the constant temperature glue tank 62 through the rectangular hole 645. When the glue flows in the opposite direction, the compression spring 644 drives the guide tube 643 to reset, thereby preventing the glue from flowing back during the injection process, resulting in unstable pressure during injection.

[0051] When injecting glue, the lifting cylinder 65 drives the pusher assembly 66 to move upward, wherein the arc surface of the elastic arc panel 661 bends toward the side away from the support block 663. When the support block 663 drives the elastic arc panel 661 to move upward through the connecting rod 662, the sealing rubber ring 664 on the outer side of the elastic arc panel 661 does not contact the inner wall of the constant temperature glue tank 62. At the same time, under the restriction of the check assembly 64, the glue can smoothly flow to the bottom of the pusher assembly 66, thereby quickly completing the filling process of the glue.

[0052] When the lifting cylinder 65 drives the pusher assembly 66 to move downward, under the resistance of the rubber material below the pusher assembly 66, the support block 663 approaches the elastic arc panel 661. At this time, under the extrusion of the connecting rod 662, the elastic arc panel 661 is deformed and forces the sealing rubber ring 664 on its outer side to contact the inner wall of the constant temperature glue liquid tank 62. At this time, the pusher assembly 66 can push the glue liquid out of the constant temperature glue liquid tank 62, thereby completing the process of rubber material filling and conveying in the process of the lifting cylinder 65 rising and falling;

[0053] At the same time, the pusher assembly 66 presses the glue in the constant temperature glue tank 62 into the glue inlet pipe 673 and the delivery hose 55 at the same time, thereby completing the glue injection process on the inside and outside of the cosmetic bottle mouth at the same time, reducing the operating steps of the staff and thus saving the time used for molding. The glue injection on the inside and outside of the bottle mouth can provide a stronger bonding force, so that the bottle mouth and related components are tightly combined. At the same time, the enhanced connection strength can ensure the integrity of the bottle mouth structure and reduce the risk of the bottle mouth loosening or damage due to external forces.
