Description

Technical Field

[0001] This utility model relates to the field of packaging structure, and in particular to a multifunctional bottle cap. Background Technology

[0002] Bottle caps, as a key component for sealing containers, are widely used in packaging bottles for beverages, food, chemicals, and pharmaceuticals. In aerosol packaging, caps are used to seal the spray valve and bottle opening, preventing leakage, evaporation, or external contamination of the contents. For aerosol bottles containing adhesive removers and other chemicals, after opening and use, the adhesive remover will remove the adhesive from the surface of the object. However, some residue will remain after removing the adhesive. If this residue is not cleaned in time, it will gradually dry and solidify, forming a solid residue that adheres to the surface of the object.

[0003] Traditional bottle caps typically employ a single-seal design, commonly including an annular sealing ring inside the cap, threaded compression seals on the outside of the bottle opening, or snap-on seals. However, these single-seal structures have significant technical drawbacks: Firstly, the seal only targets a single area at the bottle opening, lacking dual protection. When the seal wears or deforms due to long-term use, or if it doesn't fit tightly during installation, it can easily fail, leading to leakage of contents and intrusion of external impurities. This is particularly problematic for bottled products subjected to high pressure storage, frequent opening and closing, or prolonged storage. Secondly, existing sealing structures are not easy to install and remove. Some seals are fixedly connected to the cap body, meaning that once the seal ages, it cannot be replaced individually, requiring the entire cap to be replaced, increasing operating costs. On the other hand, detachable sealing structures often suffer from unstable connections and inconsistent rebound after pressing, affecting the consistency of the seal.

[0004] Meanwhile, to address the issue of residue left on surfaces after aerosol spraying, users typically need to find additional tools, such as knives, spoon handles, or specialized scrapers, for cleaning, a cumbersome process that is inconvenient to carry. While some bottle cap designs with simple scrapers exist, these designs often have significant shortcomings: either the scraper structure is too simple to effectively remove stubborn residue, or the connection between the scraper and the cap is not secure enough, making it prone to detachment or damage during use. Furthermore, these simple scraper caps often fail to achieve ideal sealing performance, making it difficult to simultaneously provide both reliable sealing and immediate cleaning.

[0005] In summary, existing bottle caps suffer from technical problems such as insufficient sealing reliability, limited functionality, lack of integrated auxiliary cleaning functions, and inconvenient replacement of seals. They cannot meet users' needs for sealing stability, ease of use, and multi-functional integration. Therefore, developing a multi-functional bottle cap that combines reliable dual sealing, integrated scraping and cleaning functions, and a reasonable structure has become a pressing technical challenge in this field. Utility Model Content

[0006] This invention provides a multifunctional bottle cap that can simultaneously and effectively seal the mouth of an aerosol bottle and conveniently scrape off adhesive residue from the surface of an object, thus solving the problem that existing bottle caps have only one function and cannot simultaneously provide reliable sealing and immediate cleaning.

[0007] To solve the above problems, this utility model provides a multifunctional bottle cap, comprising: The bottle cap body has a first sealing structure located in the inner cavity of the bottle cap body. When the bottle cap body covers the bottle mouth through the inner cavity, the first sealing structure seals the outside of the bottle mouth. The bottle cap body also has a first mating part. The second sealing structure is provided with a second mating part. The second sealing structure is installed on the bottle cap body through the first mating part and the second mating part. The second sealing structure is provided with a sealing part corresponding to the position of the bottle mouth. The sealing part is used to seal the inside of the bottle mouth. A scraping structure is provided on the second sealing structure, and the scraping structure is used to scrape off the residue.

[0008] The multifunctional bottle cap provided by this utility model has the following advantages compared with the prior art: When the bottle cap body is installed on the bottle mouth, as the bottle cap body closes, the first sealing structure located in the inner cavity of the bottle cap body comes into contact with the outer wall or end face of the bottle mouth and generates compression. Through this tight contact, the first sealing structure effectively blocks the communication between the bottle mouth and the external environment, thereby achieving the sealing of the contents of the bottle mouth. At the same time, the second sealing structure is connected and installed to the first mating part on the bottle cap body through its second mating part. After installation, the second sealing structure becomes part of the bottle cap body. Ensure that the sealing part on the second sealing structure is positioned directly opposite the bottle mouth after installation. Holding the bottle cap body with the second sealing structure installed, the sealing part is pressed against the bottle mouth, which not only retains the basic sealing function of the traditional bottle cap, but also adds a second sealing structure to increase the sealing strength. At the same time, the scraping structure set on the second sealing structure can scrape off any residual adhesive substances attached to the outside.

[0009] Preferably, the first sealing structure includes: A sealing groove is arranged in a ring shape within the inner cavity of the bottle cap body; A sealing element is located within the sealing groove, and the sealing element seals the edge of the bottle opening.

[0010] Preferably, the seal includes: A vertical sealing ring is disposed in the sealing groove, and the vertical sealing ring is fixed to the bottle cap body through the sealing groove; A horizontal sealing ring is perpendicularly connected to the vertical sealing ring. The horizontal sealing ring and the vertical sealing ring are connected, and the horizontal sealing ring seals the edge of the bottle opening through the vertical sealing ring.

[0011] Preferably, a first fixing member is provided on the bottle cap body at a position corresponding to the horizontal sealing ring, and the first fixing member abuts against the horizontal sealing ring.

[0012] Preferably, the second sealing structure includes a pressing part, on which a second mating part is provided. The pressing part is disposed on the bottle cap body through the second mating part, and the sealing part is disposed on the pressing part facing the bottle opening.

[0013] Preferably, the first mating part is configured as a limiting cavity, and the limiting cavity is arranged around the inner side of the bottle cap body; The second pairing part is configured as a limiting member, which is arranged around the periphery of the pressing part. The limiting member is located inside the limiting cavity, and an elastic member is provided at the position of the limiting member and the inner wall of the limiting cavity. The elastic member pushes the limiting member to move within the limiting cavity.

[0014] Preferably, the limiting cavity is composed of a first limiting ring and a second limiting ring, which are connected to the bottle cap body.

[0026] like Figures 1 to 5As shown in the figure, a multifunctional bottle cap provided by this utility model includes a bottle cap body 100, a second sealing structure 300, and a scraping structure 400. The bottle cap body 100 is provided with a first sealing structure 200, which is located in the inner cavity 110 of the bottle cap body 100. When the bottle cap body 100 covers the bottle mouth through the inner cavity 110, the first sealing structure 200 seals the outside of the bottle mouth. The bottle cap body 100 is provided with a first mating part 120. The second sealing structure 300 is provided with a second mating part 311. The second sealing structure 300 is installed on the bottle cap body 100 through the first mating part 120 and the second mating part 311. The second sealing structure 300 is provided with a sealing part 320 corresponding to the position of the bottle mouth, which is used to seal the inside of the bottle mouth. The scraping structure 400 is provided on the bottle cap body 100 and is used to scrape off residue.

[0027] In this embodiment of the application, a multifunctional bottle cap mainly includes a bottle cap body 100 and a second sealing structure 300. The bottle cap body 100 has a first sealing structure 200 in its inner cavity 110. When the bottle cap body 100 covers the bottle mouth, the first sealing structure 200 contacts the bottle mouth to form a seal, preventing the fluid in the bottle from spilling out and preventing external air from entering the bottle through the bottle mouth, thus preventing the fluid from deteriorating.

[0028] A first mating part 120 is provided on the bottle cap body 100, and a second mating part 311 is provided on the second sealing structure 300. The bottle cap body 100 is detachably installed by the docking of the first mating part 120 and the second mating part 311. A sealing part 320 is provided on the second sealing structure 300 at the position corresponding to the bottle mouth. The sealing part 320 is used to perform annular sealing on the bottle mouth to prevent the contents of the bottle from overflowing from the bottle mouth.

[0029] Meanwhile, a scraper structure 400 is provided on the bottle cap. This scraper structure 400 can remove adhesive residue. It can reach into the crevices of residue on external surfaces, prying up and scraping away stubborn residue. When users need to clean residue from external surfaces, they simply rotate the bottle cap body 100 to a suitable angle, align the scraper structure 400 with the residue, apply appropriate pressure, and move the bottle cap to easily scrape off the residue. The operation is simple and quick, requiring no additional cleaning tools and greatly improving ease of use.

[0030] In the above, the bottle cap of this application is installed on an aerosol bottle containing adhesive remover.

[0031] In this embodiment of the application, the first sealing structure 200 includes a sealing groove 210 and a sealing element 220. The sealing groove 210 is arranged in a ring in the inner cavity 110 of the bottle cap body 100. The sealing element 220 is located in the sealing groove 210 and seals the edge of the bottle opening.

[0032] The design of the sealing groove 210 allows the sealing element 220 to be securely installed in the inner cavity 110 of the bottle cap body 100. When the bottle cap body 100 covers the bottle mouth, the sealing element 220 fits tightly against the edge of the bottle mouth, forming an effective sealing barrier. This sealing method can effectively prevent the liquid inside the bottle from leaking, while preventing external air, moisture, etc. from entering the bottle, ensuring the quality and safety of the contents.

[0033] In this embodiment, the sealing element 220 includes a vertical sealing ring 221 and a horizontal sealing ring 222. The vertical sealing ring 221 is disposed in the sealing groove 210 and is fixed to the bottle cap body 100 through the sealing groove 210. The horizontal sealing ring 222 is vertically connected to the vertical sealing ring 221 and is connected to the vertical sealing ring 221. The horizontal sealing ring 222 seals the edge of the bottle opening through the vertical sealing ring 221.

[0034] The combined design of the vertical sealing ring 221 and the horizontal sealing ring 222 creates a dual sealing effect. The vertical sealing ring 221 primarily serves to fix and provide a preliminary seal, ensuring the stability of the sealing element 220 within the sealing groove 210. The horizontal sealing ring 222, on the other hand, directly contacts the edge of the bottle opening for sealing. This design significantly improves the reliability and durability of the seal, maintaining excellent sealing performance even under high pressure or prolonged use.

[0035] In this embodiment of the application, a first fixing member 130 is provided on the bottle cap body 100 at the position corresponding to the horizontal sealing ring 222, and the first fixing member 130 abuts against the horizontal sealing ring 222.

[0036] The first fixing member 130 further enhances the stability of the horizontal sealing ring 222, ensuring that it is not easily displaced or deformed when subjected to external forces, thereby maintaining the durability of the sealing effect. In this application, the first fixing member 130 can be a protruding structure integrally formed with the bottle cap body 100, or a fixing ring installed later, etc., so that the first fixing member 130 cooperates with the bottle mouth to support the horizontal sealing ring 222, so that the horizontal sealing ring 222 effectively seals the edge of the bottle mouth.

[0037] In this embodiment of the application, the second sealing structure 300 includes a pressing part 310, on which a second mating part 311 is provided. The pressing part 310 is disposed on the bottle cap body 100 through the second mating part 311, and the sealing part 320 is disposed on the pressing part 310 facing the bottle opening.

[0038] The pressing part 310 makes the installation and removal of the second sealing structure 300 easier. Users can connect the second sealing structure 300 to the bottle cap body 100 simply by pressing. The sealing part 320 is located at the position of the pressing part 310 facing the bottle mouth. When the pressing part 310 is pressed, it will fit into the bottle mouth, so that the outer periphery of the pressing part 310 slightly abuts against the bottle mouth to seal the bottle mouth. This ensures that the sealing part 320 can accurately contact the bottle mouth to form an effective seal.

[0039] This design not only ensures a tight seal but also provides users with noticeable feedback during operation, ensuring the sealing part 320 is accurately positioned. Simultaneously, the surface of the pressing part 310 can be designed with an anti-slip texture to increase friction between the user's fingers and the pressing part 310, preventing slippage during pressing and further enhancing ease of operation and safety.

[0040] In this embodiment, the pressing part 310 and the sealing part 320 are magnetically connected.

[0041] The magnetic connection makes installing or replacing the sealing part 320 more convenient. When installation is needed, simply bring the sealing part 320 close to the pressing part 310; under magnetic force, the sealing part 320 will automatically adhere to the pressing part 310 facing the bottle opening, achieving quick installation. Furthermore, the magnetic connection ensures the stability of the connection between the sealing part 320 and the pressing part 310 during use, preventing the sealing part 320 from falling off due to bottle shaking or external force, thus ensuring a durable seal. This magnetic connection design also facilitates individual cleaning or replacement of the sealing part 320. When the sealing part 320 wears down or its sealing performance deteriorates due to prolonged use, the user can easily remove the sealing part 320 from the pressing part 310 and replace it with a new one, extending the overall lifespan of the multi-functional bottle cap and reducing usage costs.

[0042] In this embodiment, the first mating part 120 is configured as a limiting cavity 121, which is arranged around the inner side of the bottle cap body 100; the second mating part 311 is configured as a limiting member 3111, which is arranged around the periphery of the pressing part 310. The limiting member 3111 is located inside the limiting cavity 121, and an elastic member 330 is provided at the position of the limiting member 3111 and the inner wall of the limiting cavity 121. The elastic member 330 pushes the limiting member 3111 to move within the limiting cavity 121.

[0043] The mating design of the limiting cavity 121 and the limiting member 3111 provides positioning and support for the installation of the second sealing structure 300 on the bottle cap body 100. The limiting cavity 121 is arranged around the inner side of the bottle cap body 100, providing a movable vertical movement space for the limiting member 3111. At the same time, the vertical sidewall of the limiting cavity 121 abuts against the outer periphery of the limiting member 3111, ensuring that the second sealing structure 300 maintains a certain degree of accuracy and stability during installation. The limiting member 3111 is arranged around the periphery of the pressing part 310, matching the limiting cavity 121, thus enhancing the stability of the connection.

[0044] The elastic element 330 allows the limiting element 3111 to have a certain degree of mobility within the limiting cavity 121. When the user presses the pressing part 310, the elastic element 330 is compressed, and the limiting element 3111 moves within the limiting cavity 121, causing the sealing part 320 to seal the bottle opening. When the pressing part 310 is released, the elastic element 330 returns to its original shape, pushing the limiting element 3111 and the sealing part 320 back to their initial positions, preparing for the next operation. This design not only improves the ease of operation of the product but also ensures the stability and durability of the second sealing structure 300 during repeated use.

[0045] To ensure an effective seal on the bottle opening, the pressing part 310 engages with a force greater than the elastic force of the elastic element 330. This ensures an effective seal and prevents the pressing part 310 from being pushed away by the elastic element 330, guaranteeing that the sealing effect is unaffected by the elastic force of the elastic element 330. Furthermore, this design makes the pressing part 310 more stable during pressing and rebound, reducing the shaking or jamming of the pressing part 310 caused by uneven or excessive elastic force of the elastic element 330, thus improving the user experience.

[0046] In this embodiment of the application, the limiting cavity 121 is composed of a first limiting ring 1211 and a second limiting ring 1212, and the first limiting ring 1211 and the second limiting ring 1212 are connected to the bottle cap body 100.

[0047] In this embodiment of the application, the limiting cavity 121 is composed of a first limiting ring 1211 and a second limiting ring 1212, and the first limiting ring 1211 and the second limiting ring 1212 are connected to the bottle cap body 100.

[0048] The first limiting ring 1211 and the second limiting ring 1212 further refine the structure of the limiting cavity 121. The first limiting ring 1211 and the second limiting ring 1212 work together to provide more precise positioning and restriction for the limiting member 3111. The first limiting ring 1211 and the second limiting ring 1212 can be integrally formed on the bottle cap body 100, or they can be fixed to the bottle cap body 100 by welding, snap-fitting, or other methods. The distance and shape between them can be designed according to the size and shape of the limiting member 3111 to ensure that the limiting member 3111 can move smoothly within the limiting cavity 121, while preventing the limiting member 3111 from shifting or falling off during movement. This design not only improves the accuracy of the installation of the second sealing structure 300, but also enhances the structural stability of the entire multi-functional bottle cap, making the bottle cap less prone to loosening or damage during long-term use and extending the product's service life. Furthermore, by adjusting the position and size of the first limiting ring 1211 and the second limiting ring 1212, the installation position of the second sealing structure 300 can be finely adjusted to meet the sealing requirements of bottle mouths of different specifications, thereby improving the versatility and applicability of the product.

[0049] In this embodiment of the application, a scraping inclined surface 140 is provided on the outer position of the second sealing structure 300 corresponding to the position of the scraping structure 400, and the scraping structure 400 is located on the scraping inclined surface 140.

[0050] The design of the scraping bevel 140 provides a more reasonable operating angle and point of force for the scraping structure 400. When the user uses the scraping structure 400 to clean residue from the surface of an external object, the scraping bevel 140 guides the second sealing structure 300 on the bottle cap body 100 to contact the residue at a suitable angle, allowing the scraping structure 400 to penetrate deeper into the gaps in the residue on the object, more effectively prying up and scraping away stubborn residue. Furthermore, the scraping bevel 140 increases the contact area between the scraping structure 400 and the residue, improving cleaning efficiency and reducing the time and effort required. Simultaneously, the surface of the scraping bevel 140 can be specially treated, such as polishing smooth or adding anti-slip textures, to adapt to different cleaning needs. If the residue is viscous, the smooth scraping bevel 140 can reduce the adhesion of the residue during the scraping process, making it easier to clean; if the residue is dry and hard, the scraping bevel 140 with anti-slip texture can increase friction, allowing the scraping structure 400 to function better and completely remove the residue.

[0051] In this embodiment of the application, the scraping structure 400 includes a plurality of scraping parts 410, which are evenly arranged on the scraping inclined surface 140, and the scraping parts 410 protrude from the scraping inclined surface 140.

[0052] The multiple scraper heads 410 make the cleaning process more efficient and comprehensive. Each scraper head 410 has a unique shape and angle design, enabling precise cleaning of residues of different shapes and sizes. They are evenly distributed on the scraper bevel 140, ensuring that residues from all directions are effectively scraped off when the second sealing structure 300 is rotated. The scraper heads 410 protrude from the scraper bevel 140, increasing their contact force with the residues and better peeling them off the object's surface. Moreover, this protruding design makes the scraper heads 410 more wear-resistant and less prone to damage during use, extending the service life of the scraper structure 400.

[0053] In the above, the object is the object from which residue needs to be removed, such as glass, marble tabletops, etc.

[0054] In this embodiment of the application, the scraping part 410 includes a plurality of scraping cones 411 and a plurality of scraping strips 412, the scraping cones 411 and the scraping strips 412 being used to scrape off the residue.

[0055] The combined design of the scraper cone 411 and the scraper blade 412 fully leverages the advantages of both in cleaning residues. The scraper cone 411, with its sharp shape, can penetrate deep into the tiny crevices of residues on the surface of an object, prying up stubborn and difficult-to-remove residues. Its sharp tip can apply significant pressure, easily overcoming the adhesion of residues and laying the foundation for subsequent cleaning work.

[0056] The scraper blade 412 has a relatively long shape and a large contact area. After the scraper cone 411 pries up the residue, the scraper blade 412 can quickly follow up and thoroughly scrape the residue off the object's surface. The edges of the scraper blade 412 can be designed in different shapes, such as straight lines or wavy lines, to adapt to the cleaning needs of residues of different shapes and textures. For example, for softer residues, a straight scraper blade 412 can quickly scrape them off; for harder and more angular residues, a wavy scraper blade 412 can better conform to the surface of the residue through its undulating edges, improving the cleaning effect.

[0057] The design of the scraper cone 411 and the scraper strip 412 working together makes the cleaning work more comprehensive and efficient. Whether it is small particulate residue or large stubborn residue, it can be easily cleaned, which greatly improves the practicality and cleaning effect of the multi-functional bottle cap.

[0058] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
