Description

Technical Field

[0001] The present invention relates to the technical field of medicine bottle clamping devices, and in particular to a capped medicine bottle clamping device. Background Art

[0002] Existing capped medicine bottle clamps, such as the gripping device and cleaning device for a medicine container with a cap disclosed in Chinese invention patent application number 201510314018.3, work on the principle of clamping at the cap of the medicine bottle and wrapping the capping position of the medicine bottle through an air cavity, so as to prevent moisture from invading between the bottle body and the cover body through the air curtain when cleaning the medicine bottle.

[0003] The disadvantage is that the existing medicine bottle clamp cannot form longitudinal pressure between the medicine bottle and the cover body, resulting in the risk of the gas introduced into the air cavity invading the bottle body. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a capping type medicine bottle clamp, which can ensure that the cover body is longitudinally pressed onto the medicine bottle to prevent the gas introduced into the air cavity from invading the medicine bottle.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: A capping medicine bottle clamper is used to clamp a medicine bottle and seal a cover body at the upper end of the medicine bottle, comprising: A pair of clamping blocks that can be driven to move to a state of being in contact or separation, the clamping blocks are provided with a clamping cavity and an air cavity, when the pair of clamping blocks are in a state of being in contact, the clamping cavity is used to clamp and circumferentially wrap the position of the medicine bottle corresponding to the cover body, and the pair of air cavities are combined to annularly wrap the outer periphery and lower end of the cover body; Mounting frame; A pressure cap is arranged between a pair of clamping blocks, an upper end of the pressure cap is provided with an extension rod, and the extension rod is longitudinally floatingly installed on the mounting frame; The clamp block is provided with a receiving cavity adapted to the pressure cap; A transmission structure is provided between the pressing cap and the clamping block. When the clamping block moves from a separated state to a engaged state, the transmission structure is used to drive the pressing cap to move downward a preset first distance to be tightly pressed against the upper end of the cover body. At this time, the inner wall of the storage cavity covers the radial outer side of the pressing cap, and the extension rod extends upward from the storage cavity to the outer side of the clamping block.

[0006] Furthermore, in a capping medicine bottle clamp in the present application, the clamp block is slidably mounted on a mounting frame in a horizontal direction, and a driving component for driving the clamp block to move horizontally is provided on the mounting frame; The transmission structure includes a pair of guiding inclined surfaces respectively located on the clamp block and the pressing cap. When the clamp block moves toward the engaged state, the guiding inclined surfaces on the clamp block contact the guiding inclined surfaces on the pressing cap to push the pressing cap to move downward a preset first distance.

[0007] Furthermore, in a capping medicine bottle clamp in the present application, the driving assembly includes a driving frame longitudinally slidably mounted on a mounting frame and a driver driving the driving frame to move longitudinally relative to the mounting frame, and a pair of clamps are connected to the driving frame in an oblique symmetrical sliding manner, so that the driving frame can drive the pair of clamps to open and close synchronously during the longitudinal movement. As a preferred embodiment of the present application, based on the above-mentioned device, a pair of clamps can be driven to open and close in linkage, which has the advantage of simple control. In the engaged state, the driving force of the driver can be evenly distributed to the pair of clamps to ensure a tight fit at the joints of the pair of clamps, achieve an effective water vapor isolation effect, and also ensure the consistency of the force applied to the pressure cap by the transmission structures on both sides. Ensure the stability of the movement of the pressure cap.

[0008] Furthermore, in a capping medicine bottle clamp in the present application, a pair of slide rails extending obliquely are provided on the driving frame, a transmission roller is provided on the clamp block, a spring is provided between the clamp block and the mounting frame, and the spring is used to apply elastic force to the clamp block so that the transmission roller contacts the slide rail; during the longitudinal movement of the driving frame, the slide rail can push the air cavity to move horizontally, so as to realize the synchronous movement of a pair of clamp blocks in the direction of separation or combination. As a preferred solution of the present application, relative to the sliding connection of the slide rail slider, it has the advantage of good load-bearing performance, so as to improve the service life.

[0009] Furthermore, in a capping medicine bottle clamp in the present application, the driver is a telescopic cylinder, and a limiting convex portion is provided at the end of the slide rail. When a pair of clamps are driven to separate, the limiting convex portion is used to limit the movement of the air cavity to limit the stroke of the driver. As a preferred solution of the present application, the setting of the limiting convex portion can ensure that the clamps will not move over when moving apart. The limiting convex portion limits the movement stroke of the driver, which has the advantages of simple control and cost saving compared to in-situ detection by sensors.

[0010] Furthermore, a capped medicine bottle holder in the present application, The bottom of the pressure cap is provided with a circular cavity adapted to the upper end of the cover body; The mounting frame is driven to move by the moving device; Before a pair of clamping blocks are engaged, the mounting frame is moved from top to bottom to cover the circular cavity on the upper end of the cover body; The device also includes a sensor, which is used to detect the displacement change of the pressure cap relative to the mounting frame during the process of the circular cavity being sleeved on the cover body. As a preferred solution of the present application, the disadvantages of the existing capping medicine bottle clamp also include that the medicine bottle cannot be centrally positioned relative to the clamping blocks on both sides before the clamping blocks on both sides move together, which affects the sealing after the clamping blocks are combined. Based on the above device, its principle is: by moving the mounting frame so that the circular cavity is sleeved on the cover body to ensure the position accuracy of the medicine bottle and the cover body, since the pressure cap is floatingly mounted on the mounting frame through the extension rod, if the position of the medicine bottle deviates, it will cause the cover body to abut against the outer edge of the circular cavity during the movement of the mounting frame to sleeve the circular cavity on the upper end of the cover body, causing the pressure cap to be lifted up. Therefore, the sensor can determine whether the position of the medicine bottle is accurately positioned by detecting the displacement change of the pressure cap relative to the mounting frame during this process. If the positioning error of the medicine bottle is too large to be able to be sleeved into the circular cavity, the system will alarm and terminate the subsequent operation to avoid losses.

[0011] Furthermore, in the present application, a capping medicine bottle clamp is provided on a mounting frame, an extension rod is passed through the mounting frame and longitudinally slidably connected to the mounting frame, a limit baffle is provided on the extension rod, the limit baffle is located at the upper end of the mounting frame, a compression spring is abutted between the mounting frame and the pressure cap, and the compression spring is sleeved on the extension rod. As a preferred embodiment of the present application, before the pressure cap abuts against the cover body, the limit baffle abuts against the mounting frame longitudinally to limit the downward movement of the pressure cap, before the clamping block is engaged. Based on the above device, in the process of the mounting frame moving to the process of the pressure cap abutting against the cover body longitudinally, the pressure cap is raised to a preset height h to allow the downward displacement of the pressure cap during the engagement of the clamping block. If the sensor detects that the height to which the pressure cap is raised is greater than h, it means that the cover body has not entered the circular cavity, and it can be judged that the positioning of the medicine bottle is unqualified.

[0012] Furthermore, in the capping medicine bottle holder of the present application, the sensor includes a Hall sensor and a magnetic block which are longitudinally opposite to each other, and the Hall sensor and the magnetic block are respectively arranged on the limit baffle and the mounting table. As a preferred solution of the present application, it has the advantages of simple installation and low cost compared with the photoelectric ranging sensor.

[0013] Furthermore, in the present application, a capping medicine bottle clamp, the clamp block comprises: A shell body, wherein a transverse partition is arranged in the shell body, a transmission plate is arranged on the upper side of the transverse partition, and an air inlet is arranged on the shell body; The air separation hood is installed in the shell, the air separation hood is abutted against the lower end of the diaphragm, a gas separation passage is provided between the air separation hood and the shell, the air inlet is connected with the gas separation passage, and a group of gas separation outlets connecting the gas separation passage and the air cavity are provided on the air separation hood; The chuck is mounted on the radial inner side of the gas distribution hood, and the chuck is semi-circular as a whole. The chuck includes a clamping portion abutting against the side wall of the medicine bottle and / or the cover body and an air guide portion located at the lower end of the clamping portion. The inner wall of the clamping portion forms a clamping cavity, and the air cavity includes an air inlet cavity located at the upper end of the clamping portion and an air outlet cavity located at the inner side of the air guide portion, and an air guide groove is provided on the inner wall of the clamping portion, and the air guide groove connects the air inlet cavity and the air outlet cavity. As a preferred embodiment of the present application, in the present application, the material of the chuck is elastic plastic.

[0014] Furthermore, in a capped medicine bottle holder of the present application, a steam blocking groove is provided on the inner wall of the air guide portion, and the steam blocking groove is semi-annular, including a tapered surface that is wide at the top and narrow at the bottom, and a horizontal semi-annular blocking surface at the upper end of the tapered surface. As a preferred embodiment of the present application, the steam blocking groove is used to block water vapor from rising through the air outlet cavity.

[0015] It can be seen from the above technical solution that the present invention has the following beneficial effects: The capping medicine bottle clamp in the present application, after the clamping blocks are combined, clamp the cover body through the clamping cavity, and the air cavity covers the periphery and lower end of the cover body, so as to prevent moisture from invading the medicine bottle during the cleaning process. In the process of the clamping blocks moving in the matching direction, the pressure cap is driven by the transmission structure to move to be tightly pressed on the upper end of the cover body, which can ensure that the cover body is longitudinally pressed on the medicine bottle, prevent the gas introduced into the air cavity from invading the medicine bottle, and has the advantages of simple control and high stability.

DETAILED DESCRIPTION

[0018] Example 1 Combination Figures 1 to 3 The capping medicine bottle clamp is used to clamp the medicine bottle 91 and seal the cover 92 at the upper end of the medicine bottle 91, comprising: A pair of clamping blocks 3 can be driven to move to a state of being in contact or separation, and a clamping cavity 30 and an air cavity 31 are provided on the clamping blocks 3. When the pair of clamping blocks 3 are in a state of being in contact, the clamping cavity 30 is used to clamp and circumferentially wrap the position of the medicine bottle 91 corresponding to the cover body 92, and the pair of air cavities 31 are combined to annularly cover the outer periphery and lower end of the cover body 92; Mounting frame 1; A pressure cap 2 is arranged between a pair of clamping blocks 3, and an extension rod 21 is arranged at the upper end of the pressure cap 2. The extension rod 21 is installed on the mounting frame 1 in a floating manner along the longitudinal direction; The clamp block 3 is provided with a receiving cavity 32 adapted to the pressure cap 2; A transmission structure is provided between the pressing cap 2 and the clamping block 3. When the clamping block 3 moves from a separated state to a engaged state, the transmission structure is used to drive the pressing cap 2 to move downward a preset first distance to be tightly pressed against the upper end of the cover body 92. At this time, the inner wall of the storage cavity 32 is covered on the radial outer side of the pressing cap 2, and the extension rod 21 extends upward from the storage cavity 32 to the outer side of the clamping block 3.

[0019] Based on the above structure, in the capping medicine bottle clamp of the present embodiment, after the clamp block 3 is combined, the cover body 92 is clamped by the clamp cavity 30, and the air cavity 31 covers the outer periphery and the lower end of the cover body 92, so as to prevent moisture from invading the medicine bottle 91 during the cleaning process. In the process of the clamp block 3 moving toward the combination direction, the pressing cap 2 is driven by the transmission structure to move to the upper end of the cover body 92 tightly pressed, so as to ensure that the cover body 92 is longitudinally pressed on the medicine bottle 91, and prevent the gas introduced into the air cavity 31 from invading the medicine bottle 91.

[0020] Combination Figure 2 combine Figure 3 As shown, in this embodiment, the clamp block 3 is slidably mounted on the mounting frame 1 in the horizontal direction, and the mounting frame 1 is provided with a driving assembly 4 for driving the clamp block 3 to move horizontally; the transmission structure includes a pair of guiding slopes 50 respectively located on the clamp block 3 and the pressing cap 2. When the clamp block 3 moves toward the engaged state, the guiding slopes 50 on the clamp block 3 contact the guiding slopes 50 on the pressing cap 2 to push the pressing cap 2 to move downward by a preset first distance. In this embodiment, a first guide rail 11 extending laterally is provided on the mounting frame 1, and the clamp block 3 is slidably mounted on the first guide rail 11. Combined with Figure 8 As shown, in this embodiment, a transmission plate 33 is installed in the storage cavity 32, and the guide bevel 50 is arranged on the transmission plate 33. Since the guide bevel 50 on the clamping block 3 needs to be arranged in the storage cavity 32, and the storage cavity 32 is difficult to grind, the transmission plate 33 is installed to ensure the smoothness of the guide bevel 50 on the clamping block 3.

[0021] Combination Figure 7 As shown, in this embodiment, the driving assembly 4 includes a driving frame 41 longitudinally slidably mounted on the mounting frame 1 and a driver 42 driving the driving frame 41 to move longitudinally relative to the mounting frame 1. A pair of clamping blocks 3 are symmetrically slidably connected to the driving frame 41 in an oblique direction, so that the driving frame 41 can drive the pair of clamping blocks 3 to open and close synchronously during the longitudinal movement. Based on the above device, a pair of clamping blocks 3 can be driven to open and close in linkage, which has the advantage of simple control. In the engaged state, the driving force of the driver 42 can be evenly distributed to the pair of clamping blocks 3 to ensure a tight fit at the joints of the pair of clamping blocks 3, to achieve an effective isolation effect of water vapor, and to ensure the consistency of the force applied to the pressing cap 2 by the transmission structures on both sides. Ensure the stability of the movement of the pressing cap 2. In this embodiment, a second guide rail 12 extending longitudinally is provided on the mounting frame 1, and the driving frame 41 is slidably mounted on the second guide rail 12. Combined with Figure 8 As shown, a sealing strip 34 is provided at the joint position of a pair of clamping blocks 3 .

[0022] In this embodiment, a pair of slide rails 411 extending obliquely are provided on the driving frame 41, a transmission roller 38 is provided on the clamping block 3, and a spring 52 is provided between the clamping block 3 and the mounting frame 1, and the spring 52 is used to apply elastic force to the clamping block 3 so that the transmission roller 38 abuts against the slide rail 411; during the longitudinal movement of the driving frame 41, the slide rail 411 can push the air cavity 31 to move horizontally, so as to realize the synchronous movement of a pair of clamping blocks 3 in the direction of separation or combination. Relative to the sliding connection of the slide rail slider, it has the advantage of good load-bearing performance to improve the service life. In this embodiment, the spring 52 is a tension spring, which is used to apply elastic force to the clamping block 3 to move in the direction of separation, the pair of slide rails 411 are in an eight-shaped shape, and the transmission roller 38 is a rolling bearing. In this embodiment, the driver 42 is a telescopic cylinder, and a limiting convex portion 412 is provided at the end of the slide rail 411. When driving a pair of clamping blocks 3 to separate, the limiting convex portion 412 is used to limit the movement of the air cavity 31 to limit the stroke of the driver 42. The limiting convex portion 412 can ensure that the clamping block 3 does not move over when moving away from each other. The limiting convex portion 412 limits the moving stroke of the driver 42, which has the advantages of simple control and cost saving compared to the in-position detection by the sensor. In this embodiment, the driving frame 41 is arranged in pairs on both sides of a pair of clamping blocks 3. Preferably, the telescopic cylinder is a pneumatic cylinder or a hydraulic cylinder.

[0023] The existing capping medicine bottle clamp also has the disadvantage that the medicine bottle cannot be guaranteed to be centered relative to the clamps on both sides before the clamps on both sides move together, which may affect the sealing after the clamps are combined.

[0024] In this regard, combined with Figure 2 As shown, in this embodiment, the bottom of the pressure cap 2 is provided with a circular cavity 20 adapted to the upper end of the cover body 92; The mounting frame 1 is driven to move by a moving device (not shown); Before the pair of clamping blocks 3 are engaged, the mounting frame 1 is moved from top to bottom to cover the circular cavity 20 on the upper end of the cover body 92; A sensor is also included, and the sensor is used to detect the displacement change of the pressing cap 2 relative to the mounting frame 1 when the circular cavity 20 is sleeved on the cover body 92.

[0025] Based on the above device, its principle is: by moving the mounting frame 1 so that the circular cavity 20 is sleeved on the cover body 92 to ensure the position accuracy of the medicine bottle 91 and the cover body 92, since the pressure cap 2 is floatingly mounted on the mounting frame 1 through the extension rod 21, if the position of the medicine bottle 91 deviates, it will cause the cover body 92 to abut against the outer edge of the circular cavity 20 during the movement of the mounting frame 1 to sleeve the circular cavity 20 on the upper end of the cover body 92, causing the pressure cap 2 to be lifted up. Therefore, the sensor can determine whether the position of the medicine bottle 91 is accurately positioned by detecting the displacement change of the pressure cap 2 relative to the mounting frame 1 during this process. If the positioning error of the medicine bottle 91 is too large to be inserted into the circular cavity 20, the system will alarm and terminate subsequent operations to avoid losses.

[0026] Combination Figure 2 combine Figure 5 As shown, in this embodiment, a mounting platform 13 is provided on the mounting frame 1, and an extension rod 21 is inserted through the mounting platform 13 and longitudinally slidably connected with the mounting platform 13. A limit baffle 22 is provided on the extension rod 21, and the limit baffle 22 is located at the upper end of the mounting platform 13. A compression spring 53 is abutted between the mounting platform 13 and the pressure cap 2, and the compression spring 53 is sleeved on the extension rod 21. Before the pressure cap 2 abuts against the cover body 92, the limit baffle 2 abuts against the mounting frame 13 longitudinally to limit the downward movement of the pressure cap 2 before the clamping block 3 is combined. Based on the above device, in the process of the mounting frame 1 moving to the process of the pressure cap 2 abutting against the cover body 92 longitudinally, the pressure cap 2 is raised to a preset height h to allow the downward displacement of the pressure cap 2 during the combination of the clamping block 3. If the sensor detects that the height of the pressure cap 2 being raised is greater than h, it means that the cover body 92 has not entered the circular cavity 20, and it can be judged that the positioning of the medicine bottle 91 is unqualified. In this embodiment, a linear bearing 131 is installed on the mounting platform 13 , and the extension rod 21 is slidably disposed in the linear bearing 131 .

[0027] Combination Figure 2 As shown, in this embodiment, the sensor includes a Hall sensor 61 and a magnetic block 62 which are longitudinally opposite to each other, and the Hall sensor 61 and the magnetic block 62 are respectively arranged on the limit baffle 22 and the mounting platform 13. Compared with the photoelectric ranging sensor, it has the advantages of simple installation and low cost. In this embodiment, a limit groove 132 is provided on the mounting platform 13, and the extension rod 21 is inserted into the annular cavity of the limit groove 132. The upper end of the limit groove 132 is used to limit the limit baffle 22 from moving downward, and the magnetic block 62 is arranged at the bottom of the annular cavity of the limit groove 132.

[0028] Combination Figure 3 , Figure 6 combine Figure 8 As shown, in this embodiment, the clamp block 3 includes: A housing 35, wherein a transverse partition 351 is disposed in the housing 35, the transmission plate 33 is disposed on the upper side of the transverse partition 351, and an air inlet 350 is disposed on the housing 35; The air distributor 36 is installed in the housing 35. The air distributor 36 abuts against the lower end of the transverse partition 351. A distribution channel 360 is provided between the air distributor 36 and the housing 35. The air inlet 350 is connected to the distribution channel 360. The air distributor 36 is provided with a group of air distribution outlets 361 connecting the distribution channel 360 and the air cavity 31. The chuck 37 is mounted on the radial inner side of the gas distribution cover 36. The chuck 37 is semi-circular in shape. The chuck 37 includes a clamping portion 371 abutting against the side wall of the medicine bottle 91 and / or the cover body 92 and an air guide portion 372 located at the lower end of the clamping portion 371. The inner wall of the clamping portion 371 forms a clamping cavity 30. The air cavity 31 includes an air inlet cavity 311 located at the upper end of the clamping portion 371 and an air outlet cavity 312 located at the inner side of the air guide portion 372, and an air guide groove 313 provided on the inner wall of the clamping portion 371. The air guide groove 313 connects the air inlet cavity 311 and the air outlet cavity 312. In this embodiment, the material of the chuck 37 is elastic plastic.

[0029] Combination Figure 4 As shown, in this embodiment, the inner wall of the air guide portion 372 is provided with a steam blocking groove 373, which is semi-circular and includes a tapered surface 3731 that is wide at the top and narrow at the bottom and a horizontal semi-circular blocking surface 3732 at the upper end of the tapered surface 3731. The steam blocking groove 373 is used to block water vapor from rising through the air outlet cavity 312.

[0030] Combination Fig. 9 As shown, in this embodiment, the bottom of the pressure cap 2 is provided with a first annular flange 23 and a second annular flange 24, and the first annular flange 23 and the second annular flange 24 correspond to the inner diameter and outer diameter of the mouth of the medicine bottle 91, respectively. When the pressure cap 2 is pressed on the cover body 92, the first annular flange 23 and the second annular flange 24 are sunken into the end surface of the cover body 92, so that the cover body 92 can be closely fitted with the inner and outer diameter positions of the mouth of the medicine bottle 91 to improve the sealing performance.

[0031] In other embodiments, it is necessary to press-fit the sleeve 93 onto the cover body 92 , and the sleeve cavity of the sleeve 93 is adapted to the shape of the upper end of the cover body 92 . After the sleeve 93 is wrapped around the cover body 92 , the first annular flange 23 and the second annular flange 24 can press the sleeve 93 onto the cover body 92 .

[0032] Example 2 Based on Example 1, in this example, Fig. 9As shown, a suction cup 25 is provided on the pressing cap 2 corresponding to the inner side of the first annular flange 23, and a suction cup airway 251 connecting the suction cup 25 longitudinally passes through the pressing cap 2 and the extension rod 21. The suction cup 25 is used to suck the envelope 93, and the envelope 93 is put on the cover body 92 by moving the mounting frame 1 as a whole, and then the clamping block 3 is driven to move to fit, so that the envelope 93 is tightly pressed on the cover body 92. In the natural state, the suction cup 25 protrudes from the lower end of the first annular flange 23, and a suction cup groove 230 is provided on the inner side corresponding to the first annular flange 23 for accommodating the squeezed suction cup 25 when the first annular flange 23 presses the envelope 93. Therefore, a capping type medicine bottle clamp can also transfer the envelope 93 and press the envelope 93 on the cover body 92, and has the advantage of high integration. The method of using the clamping block 3 includes the following steps: S1: The moving device (not shown) moves the mounting frame 1 as a whole to take the envelope 93, so that the envelope 93 enters the circular cavity 20, and the envelope 93 is sucked by the suction cup 25; S2: Combination Fig.10 As shown in the left figure to the middle figure, the mobile device moves the mounting frame 1 as a whole to the top of the medicine bottle 91, and moves the mounting frame 1 from top to bottom until the cover body 92 enters the sleeve cavity of the envelope 93. During this process, the pressure cap 2 is lifted up, and the elastic force of the compression spring 53 can ensure that the envelope 93 and the cover body 92 are longitudinally fitted, avoiding the friction between the sides of the envelope 93 and the cover body 92 causing the envelope 93 and the cover body 92 to be loosely fitted longitudinally; S3: The sensor detects whether the pressing cap 2 rises to a preset height h relative to the mounting frame 1 in step S2. If the rising height of the pressing cap 2 is greater than the preset height h, it indicates that the positioning of the medicine bottle 91 is deviated, and the machine stops and alarms; if the rising height of the pressing cap 2 is equal to h, step S4 is executed; S4: Combination Fig.10 As shown in the right figure, the pair of clamping blocks 3 are driven by the driving assembly 4 to move to the engaged state, at which time the medicine bottle 91 is clamped and the envelope 93 is tightly pressed onto the cover 92; S5: Move the mounting frame 1 to the cleaning station to rinse the body of the medicine bottle 91. During the rinsing process, the valve between the air inlet 350 and the air source is opened, and the air cavity 31 covers the gap between the medicine bottle 91 and the cover body 92 to prevent moisture from intruding. S6: After the cleaning is completed, the mounting frame 1 is moved to the discharging station, the driving assembly 4 drives a pair of clamping blocks 3 to move to a separated state, and the medicine bottle 91 is placed at the discharging station.

[0033] Repeat steps S1 to S6 to achieve automatic cycle operation.

[0034] In this embodiment, combined with Figures 6 to 8As shown, the lower end of the corresponding cover 92 of the medicine bottle 91 is provided with an annular retaining edge 911 for limiting the position. After the cover 92 is longitudinally pressed, it contacts the annular retaining edge 911. The inner wall of the clamping surface of the corresponding clamping portion 371 includes, from top to bottom, a first fitting surface 3711 that fits with the side wall of the cover 92, a second fitting surface 3712 that fits with the bottom of the annular retaining edge 911, and a third fitting surface 3713 that fits with the side wall of the bottleneck of the medicine bottle 91. When the cover 92 enters the sleeve cavity of the envelope 93 and the cover 92 and the envelope 93 fit tightly longitudinally, at this time, the lower edge of the envelope 93 goes downward over the annular retaining edge 911. Therefore, after step S4 is executed, combined with Fig.10 As shown in the right figure in FIG. , the sleeve 93 wraps around the lower end surface of the annular retaining edge 911.
