Description

Technical Field

[0001] This application relates to the field of powder spraying medicine bottles, and more particularly to a sealing structure for powder spraying medicine bottles. Background Technology

[0002] Powder spray bottles are packaging containers commonly used in medical, personal care, and household hygiene fields. They are mainly used to hold powdered medicines or chemicals. The cap design of existing powder spray bottles is mainly to ensure a seal when unopened. However, the cap and bottle body are connected by a simple screw. After opening, the threads between the cap and bottle body may wear down during repeated opening and closing, resulting in a poor seal. This can cause the powder inside the bottle to be affected, thus affecting the quality of the powder, causing it to deteriorate, and increasing the risk of use. Utility Model Content

[0003] The purpose of this invention is to provide a sealing structure for powder spraying medicine bottles in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a sealing structure for a powder spraying medicine bottle, including a bottle body and a bottle cap. The bottle body has a protrusion, and the bottle cap is movably mounted on the protrusion to connect the bottle body and the bottle cap. A powder suction guide is movably mounted on the bottle body. The powder suction guide includes a conduit, a tube head is provided on the conduit, and a spray head is connected to the top of the tube head. The conduit has a through hole that extends through the tube head to the outside of the spray head. An annular gasket is provided at the connection between the tube head and the spray head.

[0006] When the conduit is inside the bottle, the nozzle is embedded in the boss, so that the annular pad abuts against the top of the boss;

[0007] The inner wall of the boss is provided with a limiting groove, and the outer circumference of the tube head is provided with a protrusion that matches the limiting groove. When the tube head is located inside the boss, the protrusion is embedded in the limiting groove.

[0008] The nozzle assembly is equipped with a powder limiting seat, which has a nozzle orifice and is connected to a through hole;

[0009] The bottle cap has a sleeve and a core component inside. The core component is located inside the sleeve. When the bottle cap is installed on the boss, the core component is embedded in the nozzle orifice of the spray head component, so that part of the spray head component is located inside the sleeve.

[0010] In one embodiment, the outer periphery of the boss is provided with a protruding thread, and the inner wall of the bottle cap is provided with a concave thread that matches the protruding thread. Through the cooperation of the protruding thread and the concave thread, the bottle cap and the boss are threadedly connected.

[0011] The bottom ring of the bottle cap has a slit, and the inner wall of the bottle cap has a snap-fit ​​block. The slit is located between the snap-fit ​​block and the concave thread. Several snap-fit ​​blocks are provided and are distributed at intervals along the circumference of the bottle cap. The slit is located above the snap-fit ​​block.

[0012] The outer periphery of the boss is provided with several evenly distributed sliders, each slider having a ramp. By rotating the bottle cap on the boss, the locking block moves along the ramp between the two sets of sliders.

[0013] In one embodiment, the inner ring of the powder limiting seat is provided with an inclined end, so that the diameter of the powder limiting seat near the nozzle opening gradually increases from the diameter near the other end away from the nozzle opening.

[0014] The outer circumference of the core component is provided with an inclined opening, so that the outer circumference of the core component fits with the inclined end.

[0015] In one embodiment, the bottom of the core component has a protruding pin portion, which passes through the nozzle orifice and is located inside the through hole when the bottle cap is installed on the protrusion.

[0016] In one embodiment, a pull strip is also provided inside the bottle cap. Several pull strips are provided and evenly distributed along the circumference of the bottle cap. The pull strip has an inclined guide end, one end of which abuts against the outer circumference of the sleeve.

[0017] When the nozzle is inside the bottle cap, the nozzle is positioned between several pull strips.

[0018] In one embodiment, the outer diameter of the annular pad is the same as the outer diameter of the boss.

[0019] In one embodiment, the tube head has a cavity, and when the conduit is located inside the tube head, a gap is formed between the cavity and the conduit.

[0020] In one embodiment, the outer periphery of the bottle cap is provided with a groove, and the grooves are provided in a plurality of places and distributed at intervals along the circumference of the bottle cap, forming an anti-slip texture on the outer periphery of the bottle cap.

[0021] The advantages or beneficial effects of the above technical solutions include at least the following:

[0022] This application discloses a sealing structure for powder-spraying medicine bottles. By installing the conduit of the powder-absorbing guide inside the bottle body, the head of the conduit is embedded in a protrusion on the bottle body. Since the protrusion on the head of the conduit is embedded in the limiting groove of the protrusion, the head of the conduit is confined within the protrusion, thus completing the initial sealing of the bottle body. Furthermore, the annular gasket on the head of the conduit abuts against the protrusion, thereby further improving the airtightness of the installation. Since the bottle cap is provided with a sleeve and a core component, when the bottle cap and bottle body are installed, the nozzle of the powder-absorbing guide is embedded in the sleeve for limiting, and the core component is embedded in the nozzle orifice of the nozzle component, thereby completing the sealing of the powder-absorbing guide. This solves the problem of insufficient sealing of existing medicine bottles, which easily leads to problems with the quality of the medicine powder. Attached Figure Description

[0038] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0039] Reference Figures 1-6A sealing structure for a powder spraying medicine bottle includes a bottle body 1 and a bottle cap 2. The bottle body 1 has a protrusion 11, and the bottle body 1 and the protrusion 11 are integrally formed. The bottle cap 2 is movably installed on the protrusion 11, so that the bottle body 1 and the bottle cap 2 are connected. A powder suction guide 3 is movably installed on the bottle body 1. The powder suction guide 3 includes a conduit 31, a tube head 32 is provided on the conduit 31, and a spray head 33 is connected to the top of the tube head 32. The conduit 31 has a through hole 311, which extends through the tube head 32 to the outside of the spray head 33. The through hole 311 allows the medicine powder in the bottle body 1 to extend to the outside of the spray head 33 after being squeezed, thus completing the spraying of the medicine powder. An annular gasket 321 is provided at the connection between the tube head 32 and the spray head 33. The bottle body 1, the bottle cap 2 and the powder suction guide 3 are all made of the same PE, PP or PET material.

[0040] When the conduit 31 is inside the bottle body 1, the nozzle 33 is embedded in the protrusion 11, so that the annular pad 321 abuts against the top of the protrusion 11. The annular pad 321 can act as a barrier when the conduit 31 is installed inside the bottle body 1, preventing part of the nozzle 33 from falling into the bottle body 1, and can also play a certain role in sealing and protecting.

[0041] The inner wall of the boss 11 is provided with a limiting groove 111, and the outer circumference of the tube head 32 is provided with a protrusion 322 that matches the limiting groove 111. When the tube head 32 is located in the boss 11, the protrusion 322 is embedded in the limiting groove 111. The cooperation between the limiting groove 111 and the protrusion 322 can further improve the reliability of the seal, thereby avoiding the problem that the bottle body 1 will generate air pressure after being squeezed and deformed, and the air pressure will impact the annular gasket 321 after the squeezing is released, causing the annular gasket 321 to fall off and reduce the sealing performance.

[0042] The nozzle component 33 is provided with a powder limiting seat 331. The powder limiting seat 331 has a nozzle orifice and communicates with the through hole 311. The powder extruded from the through hole 311 can be buffered by the powder limiting seat 331 and discharged from the nozzle orifice.

[0043] The bottle cap 2 has a sleeve 21 and a core component 22 inside. The bottle cap 2, sleeve 21 and core component 22 are integrally formed together. The core component 22 is located inside the sleeve 21. When the bottle cap 2 is installed on the boss 11, the core component 22 is embedded in the nozzle orifice of the nozzle component 33, so that part of the nozzle component 33 is located inside the sleeve 21.

[0044] Based on the above structure, by placing the conduit 31 in the powder-absorbing guide 3 inside the bottle body 1, the annular pad 321 is made to fit against the top of the protrusion 11, with the tube head 32 located inside the protrusion 11 and the protrusion 322 embedded in the limiting groove 111. This allows the powder-absorbing guide 3 to be installed on the bottle body 1, achieving initial sealing of the powder inside the bottle body 1. Subsequently, the bottle cap 2 is installed on the protrusion 11 on the bottle body 1, so that the nozzle 33 is located inside the bottle cap 2, and part of the nozzle 33 is embedded in the sleeve 21 inside the bottle body 1. This allows the sleeve 21 to limit the nozzle 33, preventing shaking that could cause the nozzle 33 to detach from the bottle body 1. When the nozzle 33 is located in the sleeve 21, the core 22 is embedded in the powder limiting seat 331 of the nozzle 33, thereby sealing the through hole 311 of the guide tube 31. When the bottle body 1 is squeezed and air pressure is generated, the powder flows through the through hole 311 and is blocked by the core 22, thereby preventing the leakage of the powder. This solves the problem that existing powder spraying bottles need to be fitted with a sleeve on the nozzle 33 after opening to prevent powder leakage and make it inconvenient to use. Through the cooperation of the sleeve 21, the core 22 and the annular gasket 321, multiple sealing operations are achieved for the bottle, thereby improving the overall sealing performance of the bottle.

[0045] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 The outer periphery of the boss 11 is provided with a protruding thread 112, and the inner wall of the bottle cap 2 is provided with a concave thread 23 that matches the protruding thread 112. Through the cooperation of the protruding thread 112 and the concave thread 23, the bottle cap 2 and the boss 11 are threadedly connected. The initial connection between the bottle cap 2 and the boss 11 is achieved through the threaded connection. The threaded connection also makes it less likely for the bottle cap 2 to become loose when it is installed on the boss 11.

[0046] The bottom ring of the bottle cap 2 has a slit 24, which reduces the thickness of part of the bottle cap 2. A locking block 25 is provided on the inner wall of the bottle cap 2. The slit 24 is located between the locking block 25 and the concave thread 23. Several locking blocks 25 are provided and spaced apart along the circumference of the bottle cap 2. The slit 24 is located above the locking blocks 25. Several evenly distributed sliders 113 are provided on the outer periphery of the boss 11. Each slider 113 has a ramp 1131. The ramp 1131 of the slider 113 is designed with an inclination angle to provide progressive resistance. As the bottle cap 2 rotates on the boss 11, the locking block 25 moves along the ramp 1131 between the two sets of sliders 113. The number of sliders 113 is greater than the number of locking blocks 25. When the bottle cap 2 rotates clockwise on the boss 11 along the thread direction, the bottle cap... The bottom of the cap 2 gradually approaches the top of the protrusion 11, causing the locking block 25 to gradually approach the slider 113. Through the setting of the ramp 1131, the locking block 25 moves along the ramp 1131 of the slider 113 during clockwise rotation. When the locking block 25 is between the two sets of sliders 113, the locking between the cap 2 and the bottle body 1 is completed. When the cap 2 rotates counterclockwise, the locking block 25 will abut against the end face of the slider 113. As the user gradually applies counterclockwise rotation force, the locking block 25 will resist the slider 113, causing the cap 2 to generate a torsional force, which will pull on the cut 24 part and cause the cut 24 part to break, thereby separating the sealed medicine bottle, so that it can be sealed or opened according to the user's actual situation.

[0047] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The powder limiting seat 331 has an inclined end 3311 on its inner ring, so that the diameter of the powder limiting seat 331 gradually increases from the end near the nozzle to the end far from the nozzle. The outer circumference of the core member 22 has an inclined opening 222, so that the outer circumference of the core member 22 fits with the inclined end 3311. When the core member 22 is inserted into the powder limiting seat 331, the inclined opening 222 can correct the positional deviation of the core member 22, improve the sealing performance during installation, and when some powder adheres to the powder limiting seat 331, the inclined end 3311 guides the powder to concentrate towards the nozzle, avoiding waste of resources.

[0048] The bottom of the core component 22 has a protruding needle portion 221. When the bottle cap 2 is installed on the protrusion 11, the protruding needle portion 221 passes through the nozzle and is located in the through hole 311. The protruding needle portion 221 occupies the space of the through hole 311, which can prevent the powder from re-moistening and solidifying. When the bottle cap 2 is opened, the protruding needle portion 221 can scrape off the clumps of powder attached to the inner wall of the through hole 311 during the process of being pulled away from the through hole 311, which plays a role in unblocking.

[0049] In one embodiment, reference is made to Figure 1 and Figure 7 The bottle cap 2 is also provided with a pull strip 26. Several pull strips 26 are provided and are evenly distributed along the circumference of the bottle cap 2. The pull strip 26 has an inclined guide end 261. One end of the guide end 261 abuts against the outer circumference of the sleeve 21. Several evenly distributed pull strips 26 form a symmetrical clamping structure to ensure uniform constraint force on the nozzle 33 and avoid wear or deformation caused by local stress concentration.

[0050] When the nozzle 33 is inside the bottle cap 2, it is positioned between several pull strips 26. The guide end 261 is inclined and abuts against the outer periphery of the sleeve 21, forming an inclined guide structure. When the nozzle 33 is inserted into or removed from the bottle cap 2, the inclined surface can guide it to move along a predetermined trajectory, reducing insertion and removal resistance. At the same time, the elastic deformation of the inclined surface generates a dynamic sealing force. When the nozzle 33 is positioned between the pull strips 26, it is limited by multiple pull strips 26, which not only prevents its circumferential shaking, but also achieves axial sealing through the clamping force of the pull strips 26, thereby achieving positioning constraint on the nozzle 33, enhancing sealing performance, and improving ease of use.

[0051] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The outer diameter of the annular pad 321 is the same as the outer diameter of the boss 11. The same size can prevent powder from overflowing from the gap between the annular pad 321 and the side wall of the boss 11. The alignment of the outer edge of the annular pad 321 with the boss 11 can serve as a positioning function during installation and avoid the annular pad 321 being limited when the bottle body 1 is installed.

[0052] In one embodiment, reference is made to Figure 1 and Figure 4 The tube head 32 has a cavity 323. When the conduit 31 is located inside the tube head 32, a gap is formed between the cavity 323 and the conduit 31. The gap allows external air to enter the bottle body 1 through the cavity 323 during powder spraying, balancing the air pressure inside and outside the bottle body 1. The airflow compensation through the gap can ensure a continuous and stable output of powder. Furthermore, the gap between the conduit 31 and the tube head 32 can absorb minor deformations caused by external impacts or assembly tolerances, thereby preventing the conduit 31 from breaking due to rigid contact when subjected to external collisions.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5The bottle cap 2 has a groove 27 on its outer periphery. Several grooves 27 are provided and distributed at intervals along the circumference of the bottle cap 2. Several grooves 27 form an anti-slip texture on the outer periphery of the bottle cap 2. The anti-slip texture can enhance the friction when the user holds the bottle cap 2 and rotates it, and prevent the bottle cap 2 from sliding when the user operates with wet hands.
